Description

Technical Field

[0001] This utility model relates to the field of cable straightening technology, specifically to a cable straightening device. Background Technology

[0002] Power cables can be classified into low-voltage cables, medium-voltage cables, high-voltage cables, and ultra-high-voltage cables according to their withstand voltage. Low-voltage cables have a withstand voltage of less than 1KV, medium-voltage cables have a withstand voltage of 1KV to 10KV, high-voltage cables have a withstand voltage of 10KV to 35KV, and ultra-high-voltage cables have a withstand voltage of 35KV to 220KV. After the cables are recycled, they need to be straightened, and cable straightening devices are used to straighten the cables.

[0003] Currently, the straightening devices used in cable recycling are bulky and inconvenient to carry. They are generally set up in the factory and used in conjunction with stripping machines. Moreover, straightening devices are generally lacking during cable construction, and the cables are usually unloaded and pulled manually. The installed cables are generally in a bent state in the winding rollers, which increases the labor required for workers to pull the cables. Furthermore, the existing bulky straightening devices are not very practical and are not convenient for straightening construction on-site. Utility Model Content

[0004] The purpose of this utility model is to provide a cable straightening device, which solves the problems of the large size and inconvenience of the straightening devices used in the cable recycling process. These devices are generally set up in the factory and used in conjunction with the stripping machine. Furthermore, the cable straightening device is usually lacking during cable construction, and the cable is usually bent in the winding roller during installation, which increases the labor required for workers to pull the cable. In addition, the existing large straightening devices are not very practical and are not convenient for straightening construction on site.

[0005] This application provides a cable straightening device, including a straightening housing. A threaded block is fixedly installed at the lower end of the straightening housing. A lead screw is threaded onto the inner wall of the middle part of the threaded block. Fixed plates are rotatably installed at both ends of the lead screw. A guide mechanism for guiding the threaded block is provided between the two fixed plates. A reciprocating motor is installed on the outer wall of one of the fixed plates. The output shaft of the reciprocating motor is fixedly connected to the lead screw. Mounting holes are respectively opened on the outer walls of the two fixed plates away from the straightening housing. Multiple sets of straightening wheels are provided inside the straightening housing.

[0006] By adopting the above technical solution, the device can be installed on the bracket of the take-up roller through the mounting holes on the fixed plate and the bolts of the external equipment. During construction, the take-up roller feeds the material, and the reciprocating screw drives the screw to move back and forth, which in turn drives the threaded block and the straightening housing to move back and forth. This facilitates the straightening wheel to straighten the cable during construction. When retrieving the cable, the take-up roller rewinds, which facilitates the straightening and retrieval of twisted cables. The straightening housing is small in size, easy to carry for outdoor work, easy to install, and suitable for working in different places, thus enhancing the practicality of the straightening device.

[0007] Optionally, a set of fixed U-shaped frames is fixedly installed on two adjacent inner walls inside the straightening shell, and the two sets of fixed U-shaped frames are staggered.

The telescopic end of each set of electric push rods slides through the inner wall of the straightening housing, and a movable U-shaped frame is fixedly installed on the telescopic end of each set of electric push rods.

[0010] By adopting the above technical solution, the straightening housing can fix the electric push rod, and the electric push rod can drive the movable U-shaped frame to move, which facilitates the straightening of cables of different diameters.

[0011] Optionally, the inner walls of the movable U-shaped frame and the fixed U-shaped frame are respectively rotatably mounted to the corresponding straightening wheels.

[0012] By adopting the above technical solution, the movable U-shaped frame and the fixed U-shaped frame can respectively provide rotational support for the straightening wheel, and the straightening wheel can straighten the cable.

[0013] Optionally, a drive motor is fixedly mounted on the upper end of one of the fixed U-shaped frames, and the output shaft of the drive motor is fixedly connected to one of the straightening wheels.

[0014] By adopting the above technical solution, the drive motor can be fixed by the fixed U-shaped frame, and the drive motor can drive one of the straightening wheels to rotate. Under the frictional force between the straightening wheel and the corresponding straightening wheel, the cable is moved.

[0015] Optionally, the guiding mechanism includes two guide rods, with each end of the two guide rods being fixedly installed to a corresponding fixing plate.

[0016] By adopting the above technical solution, the guide rod can be fixed by the fixing plate.

[0017] Optionally, the two guide rods slide through the threaded block respectively, and the lead screw is located between the two guide rods.

[0018] By adopting the above technical solution, the guide rod can guide the movement of the threaded block and enhance the stability of the threaded block's movement.

[0019] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0020] 1. The technical solution of this application can be installed on the bracket of the take-up roller through the mounting holes on the fixed plate and the bolts of the external equipment. During construction, the take-up roller feeds the material, and the reciprocating screw drives the screw to move back and forth, which in turn drives the threaded block and the straightening housing to move back and forth. This facilitates the straightening wheel to straighten the cable during construction. When the cable is retrieved, the take-up roller rewinds, which facilitates the straightening and retrieval of twisted cables. This makes cable winding and retrieval convenient. In addition, the straightening housing is small in size, easy to carry for outdoor work, easy to install, and suitable for working in different places, thus enhancing the practicality of the straightening device.

[0021] 2. The drive motor can drive one of the straightening wheels to rotate. The friction between the straightening wheel and the corresponding straightening wheel will drive the cable to move.
