Introduction to the working principle and classification of the gate

Two questions for everyone to introduce the working principle and main classification of the gate:

Working principle

According to the different control methods of the movement, it is divided into mechanical, semi-automatic and fully automatic. Some manufacturers refer to semi-automatic as electric and automatic as automatic.

The mechanical type controls the movement of the blocking body (connected to the movement) by manual control, and the mechanical limit controls the movement of the movement;

Semi-automatic is to control the movement and stop of the movement by electromagnet;

Fully automatic is to control the movement and stop of the movement through the motor.

The opening and closing of the blocking body is further controlled by controlling the movement and stopping of the movement.

According to the number of movements and blocking bodies included in the same gate, the gate can be divided into a single movement (including one movement and one blocking body) and a double movement (including two movements and two blocking bodies). , in a bilaterally symmetric form).

According to the different obstacles and blocking methods, it can be divided into three roller gates, swing gates, wing gates, translation gates, turn gates, and one-word gates.

Two main types

Swing gate

The swing gate is generally called the flapping door in the rail transit industry. The shape of the blocking body (swing pendulum) is a plane with a certain area, perpendicular to the ground, and is blocked and released by rotating the swing. The material of the blocking body is commonly used in stainless steel, plexiglass, tempered glass, and some also use metal plates to outen special flexible materials (to reduce the impact of pedestrians).

It is divided into mechanical and automatic type from the movement control method. It is divided into vertical type, bridge type and cylindrical type. The vertical and cylindrical type are small in size and easy to install, but the channel length is short, the pedestrian detection module function is limited; the bridge type swing gate is long, pedestrian detection The module has stronger functions and higher security.

【advantage】

1, the range of channel width is the largest of all gates, generally between 550mm-1000mm, some high-end products can be 1500mm, more suitable for pedestrians or bicycles carrying luggage packages, can also be used for mobility Private channel.

2. Compared with the three-roll gate, the bridge swing gate has added a pedestrian pass detection module, which can effectively detect the traffic target and has strong anti-tailing capability.

3. The plasticity of the appearance form is the strongest among all the gates. The material of the blocker is rich, the shape of the box is also diversified, and it is easy to design a very beautiful shape. Therefore, it is often used in high-end occasions such as office buildings, intelligent buildings and clubs. .

4. There is no mechanical collision during the operation of the sway and the noise is relatively small.

[disadvantage]

1, the cost is higher, especially for some special customized models, such as increasing the channel width, using special material brakes, the technical difficulty will increase a lot.

2. Some models are insufficient in waterproof and dustproof capacity. They are only suitable for indoor use, and there is no three-roll gate strength for environmental adaptability.

3. Due to the limitation of the shape of the blocking body, the impact resistance of the swing gate is lower than that of the three-roller gate, and pedestrians are illegally and quickly pass to easily damage the brake pendulum and the movement.

4. If the manufacturer's design is not good, it will greatly reduce the reliability of the product, and reduce the ability of anti-pinch and anti-collision to avoid personal injury.

[Applications]

It is suitable for occasions where the channel width requirements are relatively large, including occasions where there are more pedestrians or bicycles carrying baggage packages, and dedicated passages for people with reduced mobility. It is also suitable for occasions where the aesthetic requirements are high.

Wing gate

Wing gates are generally referred to as scissor doors in the rail transit industry. Many places in foreign countries are also called speed-pass doors. The blockers (brakes) are generally fan-shaped planes, perpendicular to the ground, and are blocked and released by telescopic expansion. The material of the blocker is usually made of plexiglass or tempered glass, and some of them are also made of metal plate to wrap a special flexible material (to reduce the impact of pedestrians).

The movement control method is only fully automatic. The form is also only bridge type, and the pedestrian detection module has a strong function.

【advantage】

1. The traffic speed is the fastest among all the gates.

2. The width of the channel is between the three roller gate and the swing gate, generally between 550mm and 900mm.

3, the appearance of the shape is more beautiful, the material of the brake wing is more abundant.

4. In an emergency, the wings will be quickly retracted into the box, which can easily form barrier-free passages, improve the speed of passage, and facilitate pedestrian evacuation.

[disadvantage]

1. The control method is more complicated and the cost is higher.

2. Insufficient waterproof and dustproof capacity.

3. The appearance is relatively simple and the plasticity is not strong.

4. Due to the limitation of the shape of the blocking body, the impact resistance of the wing gate is lower than that of the three roller gate. Pedestrians can easily damage the gate and the movement.

5, the technical requirements of the manufacturer is relatively high, if the design is not good will greatly reduce the reliability of the product, as well as the ability to avoid personal injury.

[Applications]

It is suitable for indoor occasions with large traffic, such as subway and train station check-in. Also suitable for occasions where high aesthetics are required.

Turnover

The turn-off, also called the rotary gate, was developed from the three-roller gate and draws on the characteristics of the revolving door (the biggest difference is that the blocking body is not a glass door but a metal fence). According to the height of the blocking body, it is divided into full-height turning gate (also called full-high gate or full-height turning gate) and half-height turning gate (also called half-height turning gate), and the application of full-height turning gate is more.

The blocking body (brake) is generally composed of three or four metal rods that are parallel to the horizontal plane of the "丫" (also known as the three-bar turn) or the "ten" (also known as the cross gate or the cross brake).

It is divided into mechanical and semi-automatic types from the movement control method. It is divided into single channel, dual channel, three channel, four channel, etc. from the number of channels, and single channel and dual channel are relatively common.

【advantage】

1. The safety of the full-height turnstile is the highest among all the gates, and the only one that can be unattended in all gates.

2, can be very effective to achieve a single single pass, that is, only one person at a time, safety and reliability are relatively high.

3, strong waterproof and dustproof, adaptable to the environment, suitable for outdoor and indoor.

[disadvantage]

1. The channel width is generally around 500mm.

2. The traffic speed is relatively slow.

3, restricted by the shape of the blocker, not suitable for carrying luggage.

4. The plasticity of the appearance is not strong, and most of the styles are not aesthetically pleasing.

[Applications]

Full-height turnstiles are ideal for unattended and high-security applications, as well as for outdoor environments where the environment is harsh.

The semi-high turn gate is suitable for occasions where the order of passage is high, such as gymnasiums and prisons.

One word gate

One-word gate is one of the early gates. The blocking body (brake) is a metal rod. It is generally made of a hollow closed stainless steel tube. It is strong and not easily deformed. It is raised parallel to the horizontal plane and the falling gate by raising the gate. Retracted back into the box to achieve blocking and release.

The gate action of the one-word gate is 90 degrees up and down in the same vertical plane, which is easy to injure pedestrians. Therefore, it is gradually eliminated, and it is rarely used in China. The European and American markets have developed relatively early, and there are still some applications.

The movement control method is only fully automatic. The form is also only bridge type, and requires a strong pedestrian detection function, otherwise it is easy to hurt pedestrians.

Translation brake

The translation gate, also called the sliding door, the full-height gate, etc., is developed from the wing gate. It draws on the characteristics of the automatic door. The area of ​​the blocking body (brake wing) is larger, the blocking height is larger, perpendicular to the ground, and realized by telescopic Block and release. The material of the brake wing is usually made of plexiglass or tempered glass.

The movement control method is only fully automatic. The form is also only bridge type, and the pedestrian detection module has a strong function.

【advantage】

1. Strong security, due to the large area of ​​the blocking body, it can effectively prevent pedestrians from climbing and drilling illegally.

2, the appearance is very beautiful.

3, the speed is faster, similar to the wing gate.

4, the channel width is between the three roller gate and the swing gate, generally between 550mm-900mm.

5. In an emergency, the wings will be quickly retracted into the box, which can easily form barrier-free passages, improve the speed of passage, and facilitate pedestrian evacuation.

[disadvantage]

1. The control method is more complicated and the cost is higher.

2, inadequate waterproof and dustproof, generally only suitable for indoor use, if used outdoors, it is necessary to add a canopy.

3. The appearance is relatively simple and the plasticity is not strong.

4, the technical requirements of the manufacturer is relatively high, if the design is not good will greatly reduce the reliability of the product, as well as reduce the anti-clip ability to avoid personal injury.

[Applications]

Suitable for indoor applications where high security and aesthetics are required.

Three roller gate

The three-roll gate is also called three-bar gate, three-bar gate, three-roll gate, roller gate, and rolling gate. The blocking body (brake) consists of three metal rods, which are generally triangular hollow stainless steel tubes. They are strong and not easily deformed, and are blocked and released by rotation.

The three-roller gate is the earliest type of gate, and it is the most mature and perfect development to date, but it is gradually replaced by the subsequent swing gate and wing gate.

From the movement control method, it is divided into mechanical, semi-automatic and fully automatic. From the form of vertical and bridge type, the vertical three-roller gate is smaller in size and easier to install; the bridge type three-roller gate has longer passage and higher security.

【advantage】

1, can be very effective to achieve a single single pass, that is, only one person at a time, safety and reliability are relatively high.

2. The cost is lower.

3, strong waterproof and dustproof, adaptable to the environment, suitable for outdoor and indoor.

[disadvantage]

1, the channel width (refer to the width that allows pedestrians to pass) is relatively small, generally around 500mm.

2. The traffic speed is relatively slow.

3, restricted by the shape of the blocker, not suitable for carrying luggage.

4. The plasticity of the appearance is not strong, and most of the styles are not aesthetically pleasing.
