Description

Technical Field

[0001] The utility model relates to the technical field of wire stripping tools, in particular to a wire stripping tool for a live working robot. Background Art

[0002] During live operations on distribution networks, regardless of whether direct operation with insulating gloves or indirect operation with insulating rods is used, workers need to wear insulating gloves or use tools to indirectly contact live equipment to perform operations. Both operation methods require high physical fitness and skills of the workers. Continuous high-intensity work will also pose greater risks and hidden dangers to the safety of workers and line equipment.

[0003] The traditional method is to cut off the power and manually strip the wires with wire strippers. The wires are generally installed on electric poles at a corresponding height, and manual labor is required to climb up first before connecting and stripping the wires. In addition, the wires may fall during the connection process due to differences in strength control. This is not only inefficient and easy to damage the cables, but also increases the labor intensity of construction. Summary of the Invention

[0004] The purpose of the utility model is to provide a wire stripping tool for a live working robot to solve the above-mentioned defects caused by the prior art.

[0005] A wire stripping tool for a live working robot includes a tool base, a drive motor is provided directly above the tool base, a lifting mechanism is provided directly above the drive motor, the lifting mechanism clamps the live cable and adjusts the lowering height according to the stripping and cutting requirements of the wire, a wire stripping mechanism is provided on one side of the drive motor, the wire stripping mechanism performs a circular cutting on the rubber on the outside of the wire, and then strips the wire.

[0006] Preferably, the lifting mechanism includes a driving motor, a ball screw, a plate seat, a clamp, and an electric cylinder. The output end of the driving motor is connected to an active gear ring, the top of the active gear ring is connected to a ball screw, the outer side of the ball screw is connected to a plate seat, and clamps are symmetrically arranged in the middle of the plate seat, one side of one group of the clamps is connected to an electric cylinder, and the plate seat is arranged directly above the cutting ring body.

[0007] Preferably, the plate seat is connected to the back of one set of clamps via an electric cylinder connected to one side.

[0008] Preferably, the wire stripping mechanism includes a cutting ring body, a driven gear ring, a positioning tube body, a rolling bearing, an annular blade and a threaded rod.

[0009] Preferably, the driving motor is connected to a driving gear ring connected to an output end thereof in meshing connection with one side of a driven gear ring.

[0010] Preferably, the positioning tube body is connected to the compression pad via a threaded rod symmetrically arranged on the outside.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. The operator drives the active gear ring to rotate through the driving motor, and at the same time drives the driven gear ring and the annular blade on one side to rotate. During the rotation of the annular blade, the surface of the outer sheath is cut in an annular manner by the annular blade. There is no need to manually cut the surface of the cable, ensuring the stability of the cable during the stripping process.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figures 1 to 4 As shown, a wire stripping tool for a live working robot includes a tool base 1, a drive motor 2 is provided directly above the tool base 1, and a lifting mechanism 5 is provided directly above the drive motor 2. The lifting mechanism 5 clamps the live cable and adjusts the lowering height according to the stripping requirements and the wire cutting requirements. A wire stripping mechanism 8 is provided on one side of the drive motor 2. The wire stripping mechanism 8 performs a circular cutting on the rubber on the outside of the wire, thereby stripping the wire.

[0022] In this embodiment, the lifting mechanism 5 includes a driving motor 2, a ball screw 6, a plate seat 4, a clamp 11, and an electric cylinder 12. The output end of the driving motor 2 is connected to the active gear ring 3, the top of the active gear ring 3 is connected to the ball screw 6, the outer side of the ball screw 6 is connected to the plate seat 4, and the middle part of the plate seat 4 is symmetrically provided with a clamp 11, one side of one group of the clamps 11 is connected to the electric cylinder 12, and the plate seat 4 is arranged directly above the cutting ring body 7. The ball screw 6 and the plate seat 4 are driven by the driving motor 2 to perform vertical lifting and lowering, which is convenient for stripping or docking cables of different heights.

[0023] In this embodiment, the plate seat 4 is connected to the back of one set of clamps 11 through an electric cylinder 12 connected to one side. The electric cylinder 12 pushes one side of the clamp 11 to clamp and position the cable.

[0024] In this embodiment, the wire stripping mechanism 8 includes a cutting ring body 7, a driven gear ring 9, a positioning tube body 10, a rolling bearing 13, an annular blade 14 and a threaded rod 15. The bottom end of the cutting ring body 7 is connected to the rolling bearing 13, and the outer side of the rolling bearing 13 is fitted with the positioning tube body 10. The bottom end of the positioning tube body 10 is connected to the top of the tool base 1, the inside of the cutting ring body 7 is connected to the annular blade 14, and the outer side of the positioning tube body 10 is annularly connected with a threaded rod 15.

[0025] In this embodiment, the driving motor 2 is meshed with one side of the driven gear ring 9 through the active gear ring 3 connected to the output end, and the driven gear ring 9 and the annular blade 14 are driven to rotate through the active gear ring 3 to rotate the cable.

[0026] In this embodiment, the positioning tube body 10 is connected to the compression pad 16 via a threaded rod 15 symmetrically arranged on the outside. The threaded rod 15 drives the compression pad 16 to move inward, and then the compression pad 16 compresses the cable sheath.

[0027] The practical application of this live working robot stripping tool includes the following tasks:

[0028] Step 1: The operator first inserts the driven cable directly into the cutting ring body 7 and the positioning tube body 10, and adjusts the insertion depth according to the cutting requirements. The operator then holds the threaded rod 15 and uses the threaded rod 15 to drive the pressing pad 16 to rotate and move inward, and the pressing pad 16 presses the outer sheath of the cable. The operator also adjusts the width of the corresponding annular blade 14 according to the diameter of the cable so that the annular blade 14 contacts the outer sheath of the cable.

[0029] Step 2: At the same time, the cable is inserted into the inside of the two groups of clamps 11, and then the electric cylinder 12 is used to push one group of clamps 11 laterally. The guide rods are provided on the outside of the plate base 4 to guide the outside of the clamps 11. By adjusting the distance between the two groups of clamps 11, the clamps 11 are used to clamp and position the outside of the cable to prevent the cable from shaking when the annular blade 14 cuts the top of the cable.

[0030] Step 3: Then, the driving motor 2 is turned on to drive the active gear ring 3 to rotate, which in turn drives the driven gear ring 9 and the cutting ring body 7 to rotate, which in turn drives the annular blade 14 to rotate, and the annular blade 14 is used to switch the outer side of the rubber and peel off the surface of the cable. During the cutting process, the ball screw 6 and the top of the active gear ring 3 can be threadedly separated.

[0031] Step 4: After the circular cutting of the cable sheath is completed, the driving motor 2 drives the active gear ring 3 and the ball screw 6 to rotate, and the ball screw 6 drives the plate seat 4 to be vertically lifted and lowered, and the plate seat 4 and the clamp 11 are vertically lifted and lowered, and the clamp 11 drives the cable to be vertically pulled up, and the compression pad 16 presses the cable sheath after switching, so that the cable sheath is separated from the metal core inside the cable, and the operator connects the connector to the metal core.

[0032] Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
