Description

Technical Field

[0001] The present invention belongs to the technical field of circuit maintenance, and specifically relates to a parallel groove clamp installation tool. Background Art

[0002] Parallel groove clamps are mainly used for the connection of aluminum stranded wires or aluminum conductor steel-reinforced stranded wires with medium and small cross-sections, as well as the steel stranded wires of overhead lightning protection wires at positions not under tension, and are also used for the jumper connection of non-straight towers. It is an important component for connecting wires in electrical engineering materials (fittings) and is widely used in electrical line projects.

[0003] According to different structures and uses, parallel groove clamps can be divided into various types, mainly including: bolt-type parallel groove clamps: adopting a plate-plate structure, made of aluminum alloy materials, and relying on the fastening pressure of bolts to fix the connected wires in the upper and lower grooved splints to complete the connection. Bolt-type parallel groove clamps are further divided into equal-diameter parallel groove clamps and different-diameter parallel groove clamps. H-type (or C-type) parallel groove clamps: belonging to a compression structure, made of pure aluminum or aluminum alloy materials, and cannot be disassembled after installation. With the help of a special hydraulic press, the clamp and the two connected wires can be pressed into a whole. Wedge-type parallel groove clamps: provide stable contact pressure to fix the wires through the wedging of the wedge block and the elastic deformation of the body, and can connect two wires with equal diameter and different diameters. In addition, there are also spiral-type parallel groove clamps, clamping-type parallel groove clamps, pipe-piercing-type parallel groove clamps, and extrusion-type parallel groove clamps, etc. These classifications are mainly based on factors such as their clamping methods, applicable cable types, and installation environments.

[0004] When performing live work using an insulating operating rod, there is a lack of an installation tool for parallel groove clamps. Currently, when fixing wires during live wire connection, clamps are required. At present, many installations can be completed through an insulating operating rod, but most are for special-shaped clamps such as monkey head clamps, and there are very few for bolt-type parallel groove clamps. When using existing parallel groove clamps during operation, they need to be pre-fixed on the operating head, and if not fixed firmly, it is extremely easy to cause the problem of the parallel groove clamp falling off. Existing parallel groove clamps can only complete the installation of single parallel groove clamps, which does not meet the actual on-site requirements. Three operating rods are required to work simultaneously, and it is a pure manual installation, with a large operation difficulty. Summary of the Invention

[0005] In order to solve the problem that the installation of bolt-type parallel groove clamps requires manual operation with multiple insulating rods in cooperation, resulting in a large operation difficulty, the present invention provides a parallel groove clamp installation tool.

[0006] The present invention is realized through the following technical solutions: A parallel groove wire clamp installation tool comprises an insulating rod, an electric screwdriver is fixedly mounted on the top of the insulating rod, an upper chuck mounted on the insulating rod is arranged above the electric screwdriver, and a bottom surface of the upper chuck is provided with a limiting groove adapted to the parallel groove wire clamp; a parallel groove wire clamp is preset between the electric screwdriver and the upper chuck, and the electric screwdriver drives a nut on the parallel groove wire clamp to lock the parallel groove wire clamp; a switch button of the electric screwdriver is arranged at the bottom thereof, and a pull rod body rotatably arranged on the insulating rod is provided below the electric screwdriver, one end of the pull rod body corresponds to the switch button, and the other end is connected to a pull rope extending downward to the bottom of the insulating rod.

[0007] The parallel groove wire clamp is squeezed and fixed by cooperating with the electric screwdriver and the upper chuck. After lifting it to the specified height, the pull rod body is rotated to trigger the electric screwdriver to tighten the nut on the parallel groove wire clamp. This can achieve quick operation and reduce the manpower input and cumbersome operation caused by the participation of multiple insulating rods.

[0008] A further improvement of the present invention is that the end of the pull rod body away from the pull rope is provided with an inclined section for reducing the rotation angle of the pull rod body when the switch button is triggered, and the other end of the pull rod body is provided with an anti-slip protrusion for preventing the pull rope from slipping. The inclined section helps to reduce the rotation amplitude of the pull rod body when the switch button is triggered, and while completing the triggering of the switch button of the electric screwdriver, not only the operating efficiency is improved, but also the structural strength of the pull rod body is improved by means of the inclined section.

[0009] A further improvement of the present invention is that a pressing metal piece acting on the switch button is provided on the free end of the inclined section, and the pressing metal piece helps to improve the success rate of triggering the switch button.

[0010] A further improvement of the present invention is that the portion of the inclined section that carries the pressing metal piece is a deformable elastic contact, and the deformation of the elastic contact can ensure that the switch button is triggered while providing flexible protection for the switch button.

[0011] A further improvement of the present invention is that a pull rod rotating head plugged into the insulating rod is provided in the middle of the pull rod body. The pull rod body is plugged into the insulating rod through the pull rod rotating head to realize the turning of the pull rod body on the insulating rod.

[0012] A further improvement of the present invention is that a sleeve is provided on the tool head fixture at the top of the electric screwdriver, and the sleeve is adapted to the nut on the parallel groove wire clamp. A suitable sleeve is selected according to the model of the nut on the parallel groove wire clamp to complete the fast locking of the nut.

[0013] A further improvement of the present invention is that a general support extending downward is connected to the upper chuck. The lower end of the general support is connected to a base that supports the bottom of the electric screw rod. The upper chuck, the general support, and the base form a C-shaped structure as a whole. This C-shaped structure can pre-clamp and fix the electric screwdriver and the parallel groove clamp.

[0014] A further improvement of the present invention is that a button through-hole corresponding to the switch button is provided on the base. That is to say, the switch button extends downward into the button through-hole, which can prevent misoperation of the switch button and guide the rotation of the pull rod body into the button through-hole to trigger the switch button, ensuring the triggering success rate.

[0015] As can be seen from the above technical solutions, the beneficial effects of the present invention are as follows: By cooperating the electric screwdriver with the upper chuck, the extrusion and fixation of the parallel groove clamp are completed. After lifting to the specified height position, rotating the pull rod body causes the electric screwdriver to trigger the locking operation of the nut on the parallel groove clamp, which can achieve fast operation, reduce labor input, and solve the problem of cumbersome operation caused by the cooperation of multiple insulating rods.

[0021] In order to make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the specific embodiments. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this patent.

[0022] As Figure 1-2 shown, a parallel groove clamp installation tool includes an insulating rod 8. A power screwdriver 5 is fixedly installed at the top of the insulating rod 8. An upper chuck 1 installed on the insulating rod 8 is provided at an interval above the power screwdriver 5. A limiting groove adapted to the parallel groove clamp 2 is provided on the bottom surface of the upper chuck 1. A parallel groove clamp 2 is preset between the power screwdriver 5 and the upper chuck 1. The power screwdriver 5 drives the nut on the parallel groove clamp 2 to lock the parallel groove clamp 2. A sleeve 3 is provided on the tool head fixture 4 at the top of the power screwdriver 5. The sleeve 3 is adapted to the nut on the parallel groove clamp 2. Select a suitable sleeve 3 according to the model of the nut on the parallel groove clamp 2 to complete the quick locking of the nut. The switch button of the power screwdriver 5 is arranged at its bottom, and the switch button is a trigger-type physical button. A pull rod body 9 is rotatably arranged below the power screwdriver 5 on the insulating rod 8 to trigger the switch button. One end of the pull rod body 9 corresponds to the switch button, and the other end is connected to a pull rope 10 extending downward to the bottom of the insulating rod 8. Through the cooperation of the power screwdriver 5 and the upper chuck 1, the extrusion fixation of the parallel groove clamp 2 is completed. After being lifted to the specified height position, rotate the pull rod body 9 to trigger the power screwdriver 5 to lock the nut on the parallel groove clamp 2, which can achieve quick operation and reduce the cumbersome operation caused by the participation of manual labor and the cooperation of multiple insulating rods 8.

[0023] Pre-adjust the clamping degree of the parallel groove clamp 2 so that the formed size after locking after sleeving the cable is smaller than the thickness of the nut. Therefore, through the cooperation of the driven sleeve 3, the locking and fixation of the parallel groove clamp 2 can be realized.

[0024] A total support 7 extending downward is connected to the upper chuck 1. The lower end of the total support 7 is connected to a base 6 that supports the bottom of the electric screw rod. The upper chuck 1, the total support 7, and the base 6 as a whole form a C-shaped structure. This C-shaped structure can realize the pre-clamping and fixation of the power screwdriver 5 and the parallel groove clamp 2. Specifically, the power screwdriver 5 is pre-bundled together with the total support 7 on the insulating rod 8 through a cable tie. The upper chuck 1 mainly pre-assembles the parallel groove clamp 2 and the power screwdriver 5, and the base 6 supports the bottom of the power screwdriver 5. The base 6 as a whole has a right-angled bent structure, and the base 6 is detachably installed on the total support 7 through a locking member, which helps to improve the structural strength of the base 6.

[0025] The middle part of the pull rod body 9 is provided with a pull rod rotating head 94 plugged into the insulating rod 8. The pull rod body 9 is plugged into the insulating rod 8 through the pull rod rotating head 94 to realize the turning of the pull rod body 9 on the insulating rod 8.

[0026] The end of the pull rod body 9 facing away from the pull rope 10 is provided with an inclined section 93 for reducing the rotation angle of the pull rod body 9 when the switch button is triggered, and the other end of the pull rod body 9 is provided with an anti-slip protrusion for preventing the pull rope 10 from slipping. The inclined section 93 helps to reduce the rotation amplitude of the pull rod body 9 when the switch button is triggered. While completing the triggering of the switch button of the electric screwdriver 5, it not only improves the operating efficiency, but also improves the structural strength of the pull rod body with the help of the inclined section. The free end of the inclined section 93 is provided with a pressing metal part 91 that acts on the switch button. The pressing metal part 91 helps to improve the success rate of triggering the switch button.

[0027] The end of the pull rod body 9 connected to the pull rope 10 may also be provided with a rope threading hole to replace the anti-slip protrusion.

[0028] The part of the inclined section 93 that carries the pressing metal piece 91 is a deformable elastic contact 92. The deformation of the elastic contact 92 can ensure that the switch button is triggered while providing flexible protection for the switch button.

[0029] The elastic contact 92 is specifically a compression spring disposed in a groove of the pull rod body 9 .

[0030] The base 6 is provided with a button through hole 61 corresponding to the switch button, and the pressing metal piece 91 passes through the button through hole 61 and contacts the switch button. In other words, the switch button extends downward into the button through hole 61, which can prevent the switch button from being misoperated, and can also guide the pull rod body 9 to rotate into the button through hole 61 and trigger the switch button, thereby ensuring the success rate of triggering.

[0031] The parallel groove wire clamp installation tool described in the present invention completes the extrusion and fixation of the parallel groove wire clamp through the cooperation of an electric screwdriver and an upper clamp. After lifting it to a specified height position, the pull rod body is rotated to trigger the electric screwdriver to lock the nut on the parallel groove wire clamp, which can achieve quick operation and reduce the manpower input and cumbersome operation caused by the cooperation of multiple insulating rods.
