[0003] However, the cable tightening equipment used in the current cable tightening construction has a large body length, heavy weight, high cost, and complicated assembly. Usually, it is necessary to lay a track parallel to the load-bearing main cable on the ground at the lower end of the load-bearing main cable to be constructed in the main cable tightening process. , there is a track platform car on the track, a scaffold is set up on the track platform car to the lower end of the load-bearing main cable, a working platform is set on the scaffold, and a cable tightening device is placed on it, and the cable tightening device is assembled after being disassembled and transported to the working platform
This kind of cable tightening equipment has a large body, heavy weight, high cost, and complicated assembly. If the main cable breaks down, it is troublesome to repair, labor and time-consuming, high construction cost, long construction period, slow speed, low efficiency, and difficult to guarantee quality
If the distance between the load-bearing main cable and the ground is too large, or the terrain of the river is complex, it will be more difficult and costly to complete the cable tightening process

Embodiment Construction
[0019] Such as Figures 1 to 6 As shown, a cable tightening machine is mainly composed of a hydraulic system, a piercing jack and a crown block, and the cable tightening machine includes:
[0020] Running gear for moving and supporting fastening devices and hydraulic systems. The traveling device is made of crown block 1, traction lug 2, lug 17, travel pulley 3, sling 5, working platform 9, winch 20 and traction rope 19 and constitutes. The middle part of the front end of the crane is provided with traction lugs, and the hoist is located on the tower top mast 18 on the side bank of the suspension bridge. The hoist drives the crane to run through the traction rope and the traction lugs. Both sides of the lower end of the crane are provided with traveling pulleys 3, and the traveling pulleys are positioned on the load-bearing cables 21 of the catwalk. The wheel surface of the walking pulley is provided with a semicircular lower groove, which is beneficial to the running of the...

The invention belongs to a cable compacting machine comprising a travelling device, a fastening device, and a hydraulic system. The travelling device is used for moving and supporting the fastening device and the hydraulic system. The fastening device is used for rounding and compacting a plurality of parallel wire ropes into a main cable. The hydraulic system is used for providing the fastening device with rounding and compacting power. The cable compacting machine is applicable to mechanically, conveniently and quickly completing a cable rounding and compacting process for suspension bridge main cables, and has the advantages of simplicity in structure and operation, light weight, low construction cost, simplicity in assembly, time and labor saving, short construction period, safety and reliability, convenience in failure maintenance, high efficiency and good quality.
Description
technical field [0001] The invention belongs to a cable tightening machine. Background technique [0002] At present, the main cable of a suspension bridge with a large span is composed of multiple high-strength steel wire cables arranged in parallel through a round and compact cable tightening process, and then the outer parts of the round and compact multiple high-strength steel wire cables arranged in parallel The cable clips form the load-bearing main cable. The load-bearing main cable is the main load-bearing cable of the suspension bridge. There are strict requirements on the roundness and compaction of multiple high-strength steel wire cables arranged in parallel. The porosity of the main cable is below 26%. [0003] However, the cable tightening equipment used in the current cable tightening construction has a large body length, heavy weight, high cost, and complicated assembly. Usually, it is necessary to lay a track parallel to the load-bearing main cable on the ...
