[0032] In the telescopic cable laying support of the embodiment, the several rollers 3 are uniformly distributed on the tray 2. Through this setting, the balance of the support is ensured.

[0033] In the telescopic cable laying support of the embodiment, the rollers 3 are four.

[0034] In the telescopic cable laying support of the embodiment, the tray 2 is rotatably installed on the lifter 1. The tray 2 is rotatably installed on the lifter 1, and can work at an angle of 360 degrees without dead angle.

[0035] In the telescopic cable laying support of the embodiment, the lifter 1 comprises a base 11 and a telescopic sleeve 12; the bottom end of the telescopic sleeve 12 is fixedly installed on the base 11, the tray 2 is arranged on the telescopic sleeve 12 and is lifted together with the telescopic sleeve 12, the telescopic sleeve 12 is composed of several sleeve sliding sleeves, and the adjacent sleeves are fixedly connected through first fasteners 13. Through this setting, the height of the tray 2 is adjusted by adjusting the height of the telescopic sleeve 12, so as to adapt to different working heights, and the structure is simple and the operation is convenient.

[0036] Optionally, the adjacent telescopic sleeves 12 are fixedly connected through bolt cooperation with nuts, and different numbers of sleeves can be selected according to different working heights.

[0037] In the telescopic cable laying support of the embodiment, the lifter 1 further comprises an adjusting screw 14, the upper part of the adjusting screw 14 is threadedly connected with the bottom of the telescopic sleeve 12 and is locked through a second fastener 15, and the lower part of the adjusting screw 14 is threadedly connected with the base 11 and is locked through a third fastener 16. The telescopic sleeve 12 and the base 11 are connected through the adjusting screw 14, so that the height of the telescopic sleeve 12 can be finely adjusted, and more working heights can be adapted.

[0041] In the telescopic cable laying support of the embodiment, the height of the threading hole 211 is higher than the height of the cable 5.

[0042] The telescopic cable laying support meets the two forms of ground operation and high-altitude operation. When the socket circuit is threaded at a distance of 300mm from the ground, the support is lifted to more than 550mm, so that the cable 5 enters the pipe opening more smoothly. When the lighting line is threaded at the top, the support is lifted to more than 1600mm from the top, so as to ensure the safe bending radius of the cable 5 and make the threading operation easier. Three to five rollers 3 can be arranged on each support to meet the simultaneous operation of multiple persons. The telescopic cable laying support can save resources and ensure the quality of threading.

[0043] In the telescopic cable laying support of the embodiment, four 50*50*4 hot-dip galvanized angle steels are welded to form the base 11, so as to ensure the stability of the bottom. The telescopic sleeve 12 is made of a plurality of steel pipes, and the telescopic sleeve 12 and the base 11 are fastened by fasteners. The tray 2 is rotatably arranged on the telescopic sleeve 12 through a shaft sleeve, so as to realize rotation at any angle. The cable laying rack 4 is welded by 50*50*4 hot-dip galvanized angle steels, and the tray 2 can also be welded by angle steels. The roller 3 comprises a reinforcing bar 31 and a rotating pipe 32.

The reinforcing bar 31 is a threaded M32 reinforcing bar 31, and the outside of the reinforcing bar 31 is covered with a rubber sleeve. The steel pipe is a rotating point, and can simultaneously meet the requirements of 3-5 discs and 1-4mm 2 The electric wire is placed and unified from the coil. When working in the air, the telescopic sleeve 12 is pulled out. In order to ensure the stability of working in the air, the wood cushion plate 6 is arranged at the joint of the telescopic sleeve 12 and the floor, the upper part of the telescopic sleeve 12 is fastened with the wood cushion plate 6 by the screw rod 7, the fastening can be locked by the nut, the lower part of the base 11 is fastened with the ground by the jack in cooperation with the screw rod 7. The hydraulic jack is placed at the bottom of the support, the telescopic amount of 200mm is provided to make the support fixed and disassembled more quickly, the hydraulic fastening is safe and reliable, the screw rod 7 is cooperated with the hydraulic jack to make the disassembly and assembly quickly.

[0044] The construction process of the telescopic cable laying support of the embodiment is as follows:

[0045] 1, preparation stage:

[0046] The electric wire pipe is laid along the reasonable direction, the elbow is bent by the pipe bender and fixed, the pipe installation meets the specification; the support base 11 is pushed to the position near the position where the wire operation is needed, the jack is placed stably; the telescopic sleeve 12, the tray 2 and the accessories are assembled; the cable 5 is placed on the cable laying frame 4; the telescopic sleeve 12 is fastened by adjusting the adjusting screw rod 14 and the jack according to the required height; the wire drawing device is passed through the pipe at one end and pulled out at the other end; the wire heads of the electric wires needed to enter the pipe are cut off about 5cm, then one end of the electric wire is wound on the small coil at the end of the wire drawing device, or the small hole ring is used to fix it; if there are multiple wires needed to enter the same pipe, they can be twisted together and wrapped with adhesive tape.

[0047] 2, wire drawing stage:

[0048] Two people cooperate to operate, one person pulls one end of the wire drawing device, and the other person slowly puts the electric wire into the pipe at the other end of the pipe. The cable 5 is lifted to the appropriate height by the liftable tray 2, the cable 5 enters the pipe opening with a certain arc to ensure the safe bending radius of the cable 5, reduce the resistance of the cable 5 at the pipe opening, make the tension of the cable 5 not damage the protective layer and the insulation layer, and ensure the safety of the cable 5. If the electric wire is stuck, it can be gently knocked or retreated from the pipe for a small section (about 200mm) of the cable 5 to loosen it and continue to pull it out. Because the cable laying frame 4 and the tray 2 can rotate around the telescopic sleeve 12 as the shaft, the fixed support can pull out the cable 5 at multiple angles to complete the multiple loop wire drawing construction.

[0049] 3, finishing stage:

[0050] After the electric wire is completely drawn into the pipe, check whether the electric wire is firm and the pipe is damaged; loosen the jack screw to release the pressure, rely on the weight of the remaining cable 5 on the support and the self weight of the support, reset the jack, loosen the fastening screw of the screw rod 7, remove the sleeve, and disassemble the support; clean the site, and properly store the excess electric wire and the wire drawing device.
