Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of maintenance and repair tools for high-voltage power transmission equipment, in particular to a high-voltage cable joint stripping and cutting device. BACKGROUND

[0002] With the rapid development of power grid construction, high-voltage cables play an important role in urban power supply systems due to their high efficiency and stability. However, due to the complex working environment of high-voltage cables, once a fault occurs, the cable joint needs to be replaced or repaired in time, which puts higher requirements on maintenance personnel.

[0003] The existing patent (announcement number: CN218678249U) discloses a stripping and cutting device for cable head manufacturing. It includes a base, a motor is installed in the middle of the inside of the base, a gear B is arranged on the output end of the motor, and a threaded rod is sleeved on the top and bottom of the base away from the motor.

[0004] The above scheme uses the mutual cooperation between the moving ring, push rod, clamping plate, limiting plate, push block, tooth ring and pawl to clamp and fix the cable. However, in the above scheme, the pawl limits the tooth ring to complete the fixation, but the limiting of the pawl on the tooth ring in a specific position makes the tooth ring only stop rotating at these positions, so the stepless adjustment of the cable limiting cannot be completed, which leads to the problem of inaccurate limiting when fixing the cable subsequently. Moreover, the above scheme does not have the cutting size of the stripping cutter, which leads to problems such as damage to the cable insulation layer or poor joint connection. CONTENT OF THE INVENTION

[0005] In view of the deficiencies of the prior art, the present application provides a high-voltage cable joint stripping and cutting device, which has the advantages of stable limiting of cables of different sizes and determination of stripping depth, and solves the problems raised in the background art.

[0006] To achieve the above object, the application provides the following technical scheme: a high-voltage cable joint stripping and cutting device, comprising an abutting plate, the left side of the abutting plate is provided with two symmetrical clamping mechanisms, the clamping mechanism comprises a fixed frame, the side of the two fixed frames close to each other is fixedly connected with three circumferentially arranged support rods, the outer surfaces of the three support rods are slidably connected with a moving ring, the inner wall of the moving ring is provided with an annular groove, the inside of the moving ring is provided with a rotating ring, the outer surface of the rotating ring is slidably connected with the annular groove in the inner wall of the moving ring, the outer surface of the rotating ring is provided with a stripping and cutting mechanism, the stripping and cutting mechanism comprises a fixed block fixedly connected to the outer surface of the rotating ring, the inner wall of the fixed block is threadedly connected with a bolt, the bottom end of the bolt is fixedly connected with a mounting plate, the bottom surface of the mounting plate is fixedly installed with a stripping cutter, the upper surface of the mounting plate is fixedly connected with a guide scale rod, and the left side of the abutting plate is provided with a high-voltage cable body.

[0008] Through the above scheme, through the action of the clamping mechanism, when the sliding ring is rotated to cooperate with the meshing of the conical gear ring and the conical gear, the internal threaded pipe can be rotated, thereby the first lead screw can be moved and the clamping plate can be moved to the middle at the same time, different sizes of high-voltage cable bodies can be limited and fixed, and the high-voltage cable body is fixed in a threaded transmission mode, so that the fixing of the high-voltage cable body can maintain high efficiency and stability under the self-locking function of the internal thread, then through the action of the guide scale rod, the depth of stripping can be adjusted when the bolt is rotated, thereby improving the accurate stripping of the high-voltage cable body and improving the work efficiency of the staff.

[0009] Further, the upper surface of the clamping plate is fixedly connected with a guide rod, and the outer surface of the guide rod is slidably connected to the inner wall of the fixed frame.

[0010] Through the above scheme, through the action of the guide rod, when the guide rod slides on the inner wall of the fixed frame, the movement of the clamping plate can be guided, so that the clamping plate can stably move to limit and fix the high-voltage cable body, and the guide rod cooperates with the clamping plate to limit the first lead screw, so that the first lead screw will not rotate with the internal threaded pipe, thereby ensuring the stable movement thereof.

[0011] Further, the outer surface of the first screw rod is slidingly connected to the inner wall of the fixed frame.

[0012] Through the above scheme, through the action of the first screw rod, the clamping plate moves stably under the swing of the first screw rod, and the clamping plate stably clamps and fixes the high-voltage cable body under the limiting and guiding of the fixed frame, thereby improving the stability of clamping.

[0015] Further, the outer surface of the fixed block is fixedly connected with a handle.

[0016] Through the above scheme, through the action of the handle, the worker can more conveniently rotate the fixed block and the rotating ring, and the work efficiency of stripping the high-voltage cable body can be improved.

[0019] Further, the second screw rod is fixedly connected with a rotating disc at the end away from the extrusion block.

[0022] Through the above scheme, through the action of the extrusion block, the matching shape of the extrusion block and the supporting rod can make the contact between the extrusion block and the supporting rod more close, thereby improving the stability of limiting.

[0023] Compared with the prior art, the technical scheme of the present application has the following advantages:

[0024] The high-voltage cable joint stripping device, through the action of the clamping mechanism, when the rotating slip ring cooperates with the meshing of the conical tooth ring and the conical gear, can drive the inner threaded pipe to rotate, thereby driving the first lead screw to move and simultaneously driving the clamping plate to move to the middle, limiting and fixing high-voltage cable bodies of different sizes, and using threaded transmission to fix the high-voltage cable body, under the self-locking function of the internal thread, the fixing of the high-voltage cable body can maintain high-efficiency stability, and then through the action of the guide scale rod, the depth of stripping can be adjusted when the bolt is rotated, thereby improving the accurate stripping of the high-voltage cable body and improving the work efficiency of the staff.
