First, the preparation of the lower tape When the two ends of the tape are overlapped with each other, the upper tape should be aligned with the running direction. Mark the upper tape and the lower tape.
1. Cut the end of the tape neatly, and cut the diagonal line according to the width of the tape and cut it.
2. In the working section, mark the length of the connection parallel to the beveled edge, draw a line parallel to the beveled edge, and use the layering knife to layer the first layer of fabric layer along the line and tear off the first layer. Layer fabric layer. Then draw a second line parallel to the beveled edge and tear off the rubber cover layer with a certain width, and cut the rubber layer with a knife to retain the edge of the tape.
3. In the empty section, draw a straight line parallel to the beveled edge from the beveled edge of the tape, tear off the rubber cover and chamfer the rubber layer with a knife to retain the edge of the tape.
4. Other fabric layers are scratched and peeled off according to the number of layers, and the edges of the tape are retained.
Second, the preparation of the upper tape is the same as above.
3. Inspection The two ends of the tape are stacked and the joints or braids are checked for proper fit or rest. In addition, it should be noted that the edges of the ends of the tape should be aligned.
4. Stack the two connecting faces 1. Carefully clean the bonding surface and clean it without damaging the fabric layer.
2. Brush the SC2000 cold vulcanized adhesive twice with a brush on the fabric layer and the edge of the tape. The first part must be completely dry, and the second time it is dried to a semi-dry state.
3. Align the upper tape to the lower tape accurately so that the two bonding faces are completely overlapped.
4. Compact with a compaction roller to vent air.
V. Seam The two joints are painted with a mixed SC2000 cold vulcanized adhesive, or a hot vulcanized rubber + vulcanized film, and dried to a semi-dry state. Seal the seal with a sealing strip, compact the roller to discharge the air, and heat the vulcanized upper machine. Baidu included
The all-hydraulic crawler drill is a multi-purpose, internal combustion engine driven/electrically driven crawler-type full hydraulic drill that not only completes open-air blasting large-aperture drilling operations and ultra-deep hole drilling, but also achieves loose grit, alluvial, etc. The downhole impactor of the hole stratum is drilled with the pipe; it can be widely used in the anchoring hole, drainage hole, grouting hole construction of railway, highway, water conservancy, hydropower station landslide control project and dangerous rock anchoring project, and also used in blasting engineering. Construction of blastholes and tunnel pipe support holes.
The drilling rig is composed of a main machine, a hydraulic station, a console, a crawler walking device and an air compressor; the hydraulic hoses of the main machine, the hydraulic station and the operating table are connected to each other as a whole.
The power head consists of low-speed high-torque hydraulic motor, power head frame, main shaft, gear, faucet, drill pipe, and unloader.
The power head is driven by a hydraulic motor and transmitted directly to the main shaft through a gear to perform a rotary motion, thereby driving the drill pipe and the impactor to rotate. In the middle of the main shaft, a side of the power head has an outer wire joint for connecting the high-pressure hose, and an air outlet pipe of the operation table. Connected, the compressed air enters the inner hole of the main shaft through the wind faucet, and is sent to the bottom of the hole to drive the impactor through the drill pipe, and carries the cuttings formed outside the hole.
The rig structure is monolithic with a track walking chassis and a grip shackle. The crawler chassis moves quickly and the hole position is convenient; the clamping shackle can automatically remove the drill pipe and the casing, which reduces the labor intensity of the workers and improves the construction efficiency.
