Description

Technical Field

[0001] This application relates to the field of wire cutter technology, and in particular to an insulated operating lever type electro-hydraulic cutter for cutting wires during uninterrupted power supply operations. Background Technology

[0002] During the long-term operation of the power system, due to various reasons such as equipment aging, fault handling, and line renovation, it is necessary to cut the conductors in the power lines. The traditional approach is to first cut off the power and then carry out the cutting operation, but this will cause inconvenience to users and even cause significant economic losses. Therefore, the live-line cutting operation has emerged, which can maintain and renovate the power lines while ensuring the normal power supply to users.

[0003] The existing patent document "CN214626132U A Quick Wire Processing Tool with Integrated Stripping and Cutting" discloses a processing tool. Although the processing tool in the above technical solution can cut the wire, some wires are located at high positions, requiring manual climbing for operation, which is quite troublesome. At the same time, after the wire is cut, the disconnected wire may suddenly fall off and slip, which may easily lead to risk problems.

[0004] In other words, existing technologies have the following technical problems: after ordinary cutting tools cut the wire, the severed wire may suddenly detach and slip off. Therefore, to address the above problem, an insulated operating rod type electro-hydraulic cutter for cutting wires during uninterrupted power supply operations is proposed. Summary of the Invention

[0005] This embodiment provides an insulated operating lever type electro-hydraulic cutter for cutting wires without power interruption, which solves the problem that in ordinary processing tools in the prior art, the disconnected wire may suddenly fall off and slip after the wire is cut.

[0008] A hydraulic electric motor is fixedly mounted at the bottom end of an insulating rod. The hydraulic electric motor is connected to the cutting blade assembly. A battery is fixedly connected to the bottom end of the hydraulic electric motor, and the battery is electrically connected to the hydraulic electric motor.

[0009] A wire auxiliary fixing component is fixedly installed on the side wall of the cutter assembly, and is used to assist in fixing the cut wire.

[0010] Furthermore, the cutter assembly includes a fixed head, a fixed plate frame, a fixed shaft, a cutter head, a tail end, a triangular top head, and a movable push rod. The fixed head is fixedly disposed at the front end of the insulating rod, and the movable push rod is slidably connected in the inner cavity of the fixed head. One end of the movable push rod is fixedly connected to the hydraulic electric host.

[0011] Furthermore, a triangular apex is fixedly connected to one end of the movable push rod.

[0018] Furthermore, one end of a connecting spring is fixedly connected to the side wall of the circular plate, and the other end of the connecting spring is fixedly connected to the side wall of the fixed leg.

[0019] In order to solve the problem that ordinary wire cutting equipment in the prior art requires working at height when cutting wires at high positions, this application provides a convenient way to cut wires at heights by holding an insulating rod. The hydraulic electric motor is used for driving, which is more labor-saving and convenient. At the same time, in order to avoid the phenomenon that the cut wire will fall off directly when ordinary cutting equipment cuts the wire, this application further designs a wire auxiliary fixing component.

[0034] Please see Figure 1-4 As shown, an insulated operating lever type electro-hydraulic cutter for cutting power lines during uninterrupted power supply operations includes:

[0035] An insulating rod 1, with a cutter assembly 4 fixedly connected to its front end, the cutter assembly 4 being used to cut the wire;

[0036] The hydraulic electric motor 2 is fixedly installed at the bottom end of the insulating rod 1. The hydraulic electric motor 2 is connected to the cutting blade assembly 4. A battery 3 is fixedly connected to the bottom end of the hydraulic electric motor 2. The battery 3 is electrically connected to the hydraulic electric motor 2.

[0037] The wire auxiliary fixing component 5 is fixedly installed on the side wall of the cutter assembly 4, and is used to assist in fixing the cut wire.

[0038] Through the above technical solution, the wires at high places can be easily cut by holding the insulating rod 1. The hydraulic electric host 2 is used for driving, which is more labor-saving and convenient. At the same time, in order to avoid the phenomenon that the cut wires will fall off directly when ordinary cutting equipment cuts the wires, this application further designs a wire auxiliary fixing component 5. The wire auxiliary fixing component 5 can help fix the cut wires while cutting the wires, avoiding the phenomenon that the wires will fall off directly when cutting, thus making the safety higher.

[0039] The cutting blade assembly 4 includes a fixed head 401, a fixed plate frame 402, a fixed shaft 403, a cutting head 404, a tail end 405, a triangular top head 406, and a movable push rod 407. The fixed head 401 is fixedly installed at the front end of the insulating rod 1. The movable push rod 407 is slidably connected in the inner cavity of the fixed head 401. One end of the movable push rod 407 is fixedly connected to the hydraulic electric host 2. Through this technical solution, the movable push rod 407 can be moved by the operation of the hydraulic electric host 2.

[0040] A triangular jack 406 is fixedly connected to one end of the movable push rod 407.

[0041] A fixing plate frame 402 is fixedly connected to both sides of the fixing head 401, and a fixing shaft 403 is fixedly connected to the fixing plate frame 402.

[0042] Two cutting heads 404 are rotatably connected to the fixed shaft 403. The bottom of the two cutting heads 404 is fixedly provided with tail ends 405. Through this technical solution, the movement of the moving push rod 407 can push the triangular top 406 to move. The movement of the triangular top 406 can contact the tail ends 405, thereby driving the cutting heads 404 to perform a cutting motion, thereby realizing the cutting operation of the wire.

[0043] The wire auxiliary fixing assembly 5 includes a fixing bracket 501, a moving rod 502, an arc-shaped clamping plate 503, a circular plate 504, and a connecting spring 505. Four fixing brackets 501 are provided, and the four fixing brackets 501 are respectively fixed to the two side walls of the cutter head 404.

[0044] A movable rod 502 is slidably connected to the fixed bracket 501; an arc-shaped clamping plate 503 is fixedly connected to one end of the movable rod 502; and a circular plate 504 is fixedly connected to the other end of the movable rod 502.

[0045] One end of a connecting spring 505 is fixedly connected to the side wall of the circular plate 504, and the other end of the connecting spring 505 is fixedly connected to the side wall of the fixed bracket 501. Through this technical solution, when the cutting head 404 cuts the wire, the shearing movement of the cutting head 404 will also drive the arc-shaped clamping plate 503 to move. Thus, the inward clamping movement of the arc-shaped clamping plate 503 can clamp both sides of the wire, playing an auxiliary fixing role. After the wire is cut, the arc-shaped clamping plate 503 clamps and fixes the cut wire, avoiding accidents caused by the wire suddenly loosening and falling after cutting, and realizing the function of automatic fixing.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
