Conventionally, the length is selected as 1 m, and external threads M24X3 are turned at both ends by 300 mm each. The combined rods are inserted into the combined rod connection holes 14 of the guide rail base 1 to combine the two guide rail bases 1 in parallel into one body. 4 sets of M24 nuts including flat washers and spring washers are used inside and outside to ensure the stability and firmness of the combined bracket.

[0062] To further optimize the structure of this embodiment, the guide roller 3 includes a guide wheel shaft 31 and a guide wheel 32;

[0063] The guide wheel shaft 31 is concentrically combined by a shaft and a shaft sleeve, with external threads provided at both ends of the shaft.

Thus, the guide rollers 3 lift the cable pulley to roll, and the operation of coiling the cable is smooth.

[0069] The working process of this embodiment:

[0070] First, before the construction operation, the wire laying device is transported to the operation site in a split manner. At the operation site, the double guide rail bases 1 are first placed parallel on the laying area planks; first measure the distance between the cable pulley discs and the diameter. According to the distance between the cable pulleys, determine the distance between the two guide rail bases 1. Insert the two sets of combined rods 2 into the combined rod connection holes 14 of the guide rail bases 1, and tighten the combined rods 2 and the two ends of the guide rail bases 1 with connection nuts to form a combined bracket firmly.

[0071] Secondly, then select the distance between the cable pulley support points according to the cable pulley diameter, determine the front and rear distance points of the guide rollers 3 on the guide rail base 1. Assemble a set of guide rollers 3 on the guide roller limiting grooves 13 of the guide rail base 1, and tighten the locking nuts at both ends of the guide wheel shaft 31; select the corresponding positions to fix the other set of guide rollers 3 in the arrayed guide roller limiting grooves 13. There are three gear positions to choose from to ensure the ground clearance of the cable pulley. The guide rollers 3 support the rotation of the cable pulley, and the winding stress of the cable coiled on the cable pulley during the cable pulling process is completely released.

[0072] Thirdly, the size of the guide wheels 32 in the guide rollers 3 can be adjusted synchronously according to the weight, size parameters of the applied cable pulley and the guide rail base 1.

[0073] Thirdly, when laying the cable, the construction workers push the cable pulley, and it rolls along the 30° slope 12 of the guide rail base 1 and lands at the center of the guide wheel 32, then the wire laying work can start. It can meet the convenient erection of the cable pulley without hoisting operation.

[0074] Finally, after the cable laying construction is completed, roll the cable pulley down along the 30° slope 12 of the guide rail base 1; disassemble the guide rollers 3 and the combined rods 2 and put them away for standby.

[0075] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
