Abstract

The invention discloses a cable snakelike bending machine. The cable snakelike bending machine comprises a back shore, a stress supporting tool, a pressure sensor, a jacking mechanism, a rack mechanism and a bending roller which are sequentially connected from head to tail, wherein the jacking mechanism comprises a lead screw, a turbine mechanism, a hand-cranking wheel and a rocking wheel input shaft; the lead screw is vertically arranged in the turbine mechanism in a penetrating mode, the rocking wheel wheel input shaft is transversely arranged in the turbine mechanism, and the lead screw and the rocking wheel input shaft are meshed together through a gear; the hand-cranking wheel is located on the outer side of the turbine mechanism and connected with the rocking wheel input shaft; and the upper end of the lead screw is connected with the pressure sensor, and the lower end of the lead screw extends into the rack mechanism. According to the method, the working efficiency is effectively improved, and the project expenditure is reduced; and the cable laying quality is improved, and the S-shaped laying of the cable is ensured to meet the technical requirements. According to the invention, the pressure borne by the cable and the snake-shaped wave amplitude during bending can be accurately displayed, the construction standard can be conveniently formulated, and the installation precision and the maintenance convenience are also guaranteed.

Description

technical field [0001] The invention relates to the field of cable laying engineering construction, in particular to a cable serpentine bending machine. Background technique [0002] For power cables, due to real-time changes in ambient temperature and operating load, large thermomechanical stresses will be generated inside the cables, especially for large cross-section cables, the internal stress of the cables caused by thermal expansion and contraction will cause damage to the cables , affect the normal operation of the cable, in order to effectively eliminate the thermal mechanical stress inside the cable, in accordance with the requirements of the "Power Cable and Channel Operation and Maintenance Regulations (Q / GDW1512-2014)", the serpentine amplitude of the cable laying should be accurately controlled during the construction process, effectively Offset the cable line length change caused by the thermal expansion and cold shrinkage of the cable line to ensure the safety...
