Description

Technical Field

[0001] The utility model relates to the field of cable repair, in particular to an insulation layer winding machine for cable repair. Background Art

[0002] During long-term use of the cable, if the cable is damaged due to high-voltage breakdown or environmental factors, or if the length of the cable is less than the required length of the cable, and the cable needs to be continued, the surface layer of the cable needs to be peeled off first, and then the conductors of the cable are connected, and then the insulation layer, strength layer and other structures are wrapped on the surface of the conductor to ensure the insulation and sealing of the cable to comply with electrical insulation regulations.

[0003] Traditionally, insulation layer wrapping is mostly done manually, but the winding force of manual wrapping is uneven, resulting in uneven thickness of the insulation layer, which can easily cause cable structural defects and high-voltage breakdown. At the same time, some long-distance winding operations can easily fatigue operators, resulting in poor uniformity and neatness of the wrapping, and can also easily cause cable structural defects and high-voltage breakdown. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide an insulation layer winding machine for cable repairing, which can wind an insulation layer on the conductor surface of a damaged cable or a cable that needs to be connected.

[0005] The technical solution adopted by the utility model to solve the above-mentioned problem is: an insulation layer winding machine for cable repair, comprising a main body, the main body comprising a movable seat and an insulation layer winder, the movable seat is provided with a movable guide rail, the insulation layer winder is movably connected to the movable guide rail through a connecting arm, one end of the connecting arm is movably connected to the movable guide rail, and the other end of the connecting arm is fixedly connected to the insulation layer winder, the main body also includes a clamp assembly for fixing the cable, and the fixed cable is parallel to the movable guide rail.

[0006] Compared with the prior art, the advantages of the utility model are: through the design of the movable seat and the movable guide rail, the stability of the movement of the insulation layer winder can be guaranteed, thereby ensuring the uniformity of the insulation layer winding and the winding quality, and the design of the clamp assembly can ensure the position stability of the cable to be wound with the insulation layer, and then when the insulation layer is wound on the conductor, it can be ensured that the insulation layer winder moves along the cable, ensuring high-quality winding of the insulation layer on the conductor.

[0007] As an improvement of the utility model, the connecting arm is composed of multiple universal damping rotating joints connected end to end. Through the improvement, the insulation layer winder can be more applicable. When the distance and angle between the clamp assembly and the movable seat change, the position of the insulation layer winder can be adjusted by changing the connecting arm to ensure high-quality winding of the insulation layer winder without adjusting the clamp assembly or the movable seat.

[0008] As an improvement of the present invention, the insulation layer winder includes a connecting seat and a winding disk, the connecting seat is used to be fixedly connected to the connecting arm, the winding disk is rotatably connected to the connecting seat, and a winding belt is installed in the winding disk. Through the improvement, the insulation layer winding of the insulation layer winder is realized.

[0009] As an improvement of the utility model, a winding hole is provided in the axial direction of the winding disk, a winding embedding groove is provided on the side of the connecting seat away from the connecting arm, and an embedding directional groove is provided on the winding disk. When the winding embedding groove and the embedding directional groove are in the same direction, the cable can enter the winding hole from the radial direction. Through the improvement, the cable can be placed in the axial direction of the winding disk in the radial direction of the cable without having to put the winding disk on the cable from the end of the cable, which is more suitable for repair work.

[0010] As an improvement of the utility model, a transmission connecting tooth is provided on the circumference of the winding disk, and at least two transmission driving teeth meshing with the transmission connecting teeth are provided in the connecting seat. At least two of the transmission driving teeth are connected by the same winding motor drive. Through the improvement, the rotation of the winding disk is realized to ensure that the winding disk can wind the insulating layer. At the same time, due to the design of embedding the directional groove, there will be a transmission gap in the winding disk, so the design of at least two transmission driving teeth is required to ensure the continuity of the drive.

[0011] As an improvement of the utility model, the clamp assembly includes two fixing clamps for clamping the cable and two supporting clamps for ensuring the horizontality of the cable in the clamped state, and the two supporting clamps are arranged between the two fixing clamps. Through the improvement, through the design of the supporting clamps and the fixing clamps, the straightness of the cable during the clamping process can be better guaranteed, thereby better ensuring that the insulation layer winder always moves with the cable as the axis during the movement process.

[0012] As an improvement of the utility model, an adjusting screw is provided between the two fixing clamps, and the distance between the two fixing clamps is adjusted by rotating the adjusting screw. Through the improvement, during the process of clamping the cable, the cable between the two fixing clamps may sink. At this time, by rotating the adjusting screw, the distance between the two fixing clamps is increased to lengthen the cable and eliminate the sinking, thereby ensuring that the insulation layer winder always moves with the cable as the axis during the movement.
