Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary devices for distribution network construction, in particular to a cable lifting device for distribution network construction. Background Art

[0002] With the continuous development and progress of society, people's lives are gradually improving, and therefore, the facilities around them are also constantly improving. Currently, my country is vigorously carrying out a distribution network construction and renovation plan, focusing on the construction of distribution networks in rural areas. Distribution is the link in the power system that directly connects to users and distributes electrical energy to them. The distribution system consists of distribution substations, high-voltage distribution lines, distribution transformers, low-voltage distribution lines, and corresponding control and protection equipment. The cables used in distribution construction are power or signal transmission devices, usually composed of several or several groups of conductors. During distribution network construction, cable hoists are usually required to lift the cables for construction.

[0003] An existing patent (publication number: CN213505337U) discloses a cable lifting device for distribution network construction, including a base, a winding roller, a fixed pulley, a movable plate, a locking bolt, a slide, a screw, a fixed column, a slide rail, a sliding sleeve, a slider, a drive slot, a motor, a mounting slot, casters, a connecting column, a connecting rod, a pressure plate, a piston rod, a spring, a connecting shaft, a second slider, a fastening bolt, a connecting screw, a positioning sleeve, and a fastening pad. The utility model can quickly raise the cable height through the motor, screw, sliding sleeve, slide rail, and slider, facilitating distribution network construction. The connecting column, connecting rod, pressure plate, piston rod, and spring can conveniently act as a shock absorber during cable transportation to prevent the cable from falling off or scattering. The slide, second slider, fastening pad, movable plate, connecting screw, and positioning sleeve can quickly secure the cable. It can also conveniently secure cables of different diameters. The connecting shaft and locking bolt can conveniently adjust the angle, facilitating distribution network construction.

[0004] When the above patented technology is in use, it guides the cable through the fixed pulley, passes the cable around the bottom of the fixed pulley, and supports the cable. When the cable is lifted, the force of pulling the cable causes the winding roller to spit out the cable. When the winding roller rotates to spit out the cable due to friction and cannot withstand the tension, when the cable passes through the fixed pulley, one end of the cable is lifted upward, which will cause the cable to generate a pulling force on the fixed pulley. Since the fixed pulley and the base are fixedly connected, the cable may be torn off and damaged. Therefore, a cable lifting device for distribution network construction is proposed.

After lifting to the specified height, you only need to pull the pull rod 18 to contact the limit on one end of the cable, which is convenient for construction workers to operate at height.
