Description

Technical Field

[0001] This utility model relates to the field of power testing technology, specifically to a high-altitude wiring device for high-voltage testing. Background Technology

[0002] High-voltage testing aerial wiring devices are mainly used to safely connect conductors to equipment at high altitudes during high-voltage testing in power systems. The aerial wiring devices can be operated from the ground, avoiding the need for operators to climb high, thus completing the wiring task quickly and conveniently, saving time and manpower.

[0003] Existing high-altitude wiring pliers require force to push or pull the handle of the pliers to close the jaws and clamp the wire when clamping the wire. After clamping the wire, the operator needs to check whether the jaws are fully closed and whether the wire is firmly clamped. Sometimes it is also necessary to gently shake the wire or the jaws to ensure the stability of the connection.

[0004] Secondly, after clamping the wire, it is necessary to manually lock it through a locking mechanism to prevent the pliers from accidentally opening. When releasing the wire after completing the wiring task, the opposite operation is required. As a result, the multi-step operation and complex locking mechanism of the existing high-altitude wiring pliers may lead to longer operation time and increased uncertainty in the test, especially in temporary operations that require quick clamping and release, such as on-site testing and short-term wiring.

[0005] Therefore, how to design a high-voltage testing high-altitude wiring device that can quickly perform clamping and releasing operations during on-site testing or short-term wiring is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the purpose of this utility model is to provide a high-altitude wiring device for high-voltage testing, so as to solve the technical problem that the existing high-altitude wiring clamps cannot clamp and release quickly and well to meet the requirements during on-site testing or short-term wiring.

[0007] This utility model is achieved through the following technical solution:

[0008] A high-altitude wiring device for high-voltage testing includes an operating rod and a clamp head mounted on the top of the operating rod. The clamp head includes a jaw A and a jaw B for cooperating with the jaw A to clamp a wire. An elastic support mechanism is installed below the jaw B. In the initial state, the jaw B abuts against the lower part of the jaw A under the action of the elastic support mechanism.

[0009] A pulling mechanism is installed at the bottom of the gripper B, and a handle is installed at the bottom of the operating rod. The handle can control the gripper B to open away from the gripper A through the pulling mechanism.

[0010] Furthermore, the pliers head also includes a pliers body fixedly connected to the operating lever, the pliers body having an inner cavity for mounting the grippers;

[0011] Sliding grooves are provided on the opposite two side walls of the inner cavity, and a slider is slidably connected in the sliding groove. The slider is fixedly connected to the gripper B.

[0012] An installation block is also fixedly connected to the slide groove, and the installation block is fixedly connected to the gripper A.

[0013] Furthermore, the elastic support mechanism includes a sleeve fixedly connected to the bottom wall of the inner cavity, an elastic element installed in the sleeve, and a support rod inserted in the sleeve, the support rod abutting against the slider under the force of the elastic element.

[0014] Furthermore, the pulling mechanism includes a pulling seat fixedly connected to the bottom of the slider, a pulling rope connected to the pulling seat, the other end of the pulling rope extending out of the clamp head, and a hook for hooking with the handle fixedly connected to its end.

[0015] Furthermore, a mounting base is fixedly connected to the outer surface of the operating lever.

[0016] Furthermore, a guide seat is fixedly connected to the clamp body, and the guide seat is located on the movement trajectory of the pulling rope;

[0017] The guide seat is concave, and two guide rods are rotatably connected to the guide seat at a distance from each other. The pull rope is threaded between the two guide rods.

[0018] Furthermore, the handle includes a grip portion connected to the operating lever, and an operating portion hinged to the grip portion, the operating portion being hooked to the hook.

[0019] Furthermore, the operating lever includes a lever body, the top of which is a threaded portion;

[0020] The pliers head also includes a connecting sleeve fixedly connected to the bottom of the pliers body, and the bottom of the connecting sleeve has a connecting port for threaded connection with the threaded portion.

[0021] The handle controls the pulling mechanism to pull the jaw B downwards and slide it away from the jaw A, causing the clamp head to open. Then, the jaw head is hooked onto the wire. After hooking, the handle is released, and the jaw B is pushed upwards and reset under the action of the elastic support mechanism. It cooperates with the jaw A to quickly clamp the wire. To release the wire, simply squeeze the handle to achieve quick release.

[0022] 2. The high-altitude wiring device of this utility model can automatically clamp the wire by the clamp head driven by the elastic element, without the operator having to manually push or pull the complicated mechanical handle, which simplifies the operation steps. Furthermore, the deformation of the elastic element enables the clamp head to respond quickly to the operation, making the operation simpler. The wiring operation can be performed simply by squeezing the operating part.

[0023] 3. When clamping the wire, simply loosen the elastic element of the operating part and it will automatically reset to close the clamping head and clamp the wire. This greatly reduces the operation time and complexity, and the operator does not need to apply force frequently.

[0024] Meanwhile, no additional locking mechanism is required, making operation simpler and faster, saving the manufacturing and maintenance costs of the locking mechanism. The constant pressure provided by the elastic element can ensure that the wire is firmly clamped, reducing the risk of slippage. This makes the high-altitude wiring device of this utility model more suitable for clamping lightly loaded wires or cables, such as home electrical repair, small appliance assembly, or temporary operations that require quick clamping and release, such as on-site testing and short-term wiring.

[0035] Typical embodiments embodying the features and advantages of this utility model will be specifically described in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0036] In the description of this application, the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0037] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a high-altitude wiring device for high-voltage testing, including an operating rod 1 and a clamp head 2 installed on the top of the operating rod 1. The operating rod 1 is hollow, and both the operating rod 1 and the clamp head 2 are made of high-strength insulating material. As for how to ensure insulation, this is existing technology and will not be elaborated on here.

[0038] Please see Figure 1 and Figure 2 The operating lever 1 includes a lever body 11, the top of which is a threaded portion 12. The pliers head 2 includes a pliers body 26 and a connecting sleeve 31 fixedly connected to the bottom of the pliers body 26. The bottom of the connecting sleeve 31 has a connecting port 32 for threaded connection with the threaded portion 12. Specifically, the lever body 11 is threadedly connected to the connecting port 32 through the threaded portion 12, allowing it to be detachably installed below the connecting sleeve 31 for easy storage and carrying. The pliers body 26 is inserted into the top of the connecting sleeve 31 and is fixed to the connecting sleeve 31 by bolts.

[0039] Please see Figure 3 The clamp body 26 has an inner cavity 27 for mounting the gripper. Slide grooves 28 are provided on the opposite side walls of the inner cavity 27. A slider 29 is slidably connected in the slide groove 28, and a gripper B22 is fixedly connected to the slider 29.

[0040] A mounting block 30 is also fixedly connected to the slide groove 28 by bolts. A clamping claw A21 is fixedly connected to the mounting block 30. The clamping claw A21 is located above the clamping claw B22. The clamping claw A21 is used to cooperate with the clamping claw B22 to clamp the wire. The clamping claw in this utility model is composed of multiple clamping blocks spaced apart to achieve lateral widening. Compared with the single-headed clamping claw in the prior art, the laterally widened clamping claw can provide a larger clamping area, thereby enhancing the clamping force and better dispersing the pressure, making the clamping head 2 more stable when clamping the wire.

[0041] Secondly, the single-head chuck in the prior art may wear down after long-term use, resulting in a decrease in clamping force. However, the widened jaws of this invention can distribute wear and extend the service life of the chuck head 2. Furthermore, when the chuck head 2 is damaged, the damaged jaws can be disassembled and replaced individually, which is convenient for maintenance and saves maintenance costs.

[0042] Please see Figure 3 and Figure 4 An elastic support mechanism 23 is installed below the gripper B22. In the initial state, the gripper B22 abuts against the lower part of the gripper A21 under the action of the elastic support mechanism 23.

[0043] The elastic support mechanism 23 includes a sleeve 231 fixedly connected to the bottom wall of the inner cavity 27. An elastic element 232 is installed in the sleeve 231, and a support rod 233 is inserted into the sleeve 231. The support rod 233 abuts against the slider 29 under the force of the elastic element 232, so that in the initial state, the gripper B22 and the gripper A21 abut and close. In this application, the elastic element 232 is a spring. By assembling the elastic element 232 in the sleeve 231, the influence of the external environment on the service life of the elastic element 232 can be reduced, so as to provide a stable clamping force.

[0044] Please see Figure 1 , Figure 3 and Figure 4 The bottom of the gripper B22 is equipped with a pulling mechanism 24, and the bottom of the operating lever 1 is equipped with a handle 25. The handle 25 can control the gripper B22 to open away from the gripper A21 through the pulling mechanism 24.

[0045] The pulling mechanism 24 includes a pulling seat 241 fixedly connected to the bottom of the slider 29. A pulling rope 242 is connected to the pulling seat 241. The other end of the pulling rope 242 extends out of the clamp head 2, and its end is fixedly connected to a hook 243 for hooking with the handle 25.

[0046] The handle 25 includes a gripping part 251 connected to the operating lever 1, and an operating part 252 hinged to the gripping part 251. The operating part 252 is hooked to the hook 243. By squeezing the operating part 252, the operating part 252 swings on the gripping part 251 and pulls the jaw B22 away from the jaw A21 through the pull rope 242. At this time, the clamp head 2 opens and can clamp the wire.

[0047] Please see Figure 1 , Figure 3 and Figure 5 A guide seat 245 is fixedly connected to the clamp body 26. The guide seat 245 is located on the movement trajectory of the pulling rope 242. The guide seat 245 is concave. Two guide rods 246 are rotatably connected to the guide seat 245 at intervals. The pulling rope 242 passes between the two guide rods 246. The guide rods 246 can assist the movement of the pulling rope 242 and limit the range of motion of the pulling rope 242 to prevent the pulling rope 242 from getting tangled.

[0048] A hanging seat 244 is fixedly connected to the outer surface of the operating rod 1, and multiple hooks 243 can be spaced apart on the pull rope 242. Specifically, the operating rod 1 can be a telescopic rod as in the prior art. When controlling the length of the operating rod 1 to perform wiring operations at different heights and the telescopic rod is not fully extended, the hook 243 at the very end of the pull rope 242 can be hooked onto the hanging seat 244, and one of the hooks 243 at a suitable position on the pull rope 242 can be hooked onto the operating part 252, so as to store the excess length of the pull rope 242, while ensuring that squeezing the operating part 252 can drive the jaws to open.

[0049] The working principle of this utility model is as follows: When the operating part 252 is squeezed, the operating part 252 and the holding part 251 swing relative to each other, and the hook 243 pulls the pulling rope 242. At this time, the pulling rope 242 pulls the slider 29 downward along the groove 28 through the pulling seat 241. When the slider 29 slides downward, it squeezes the support rod 233 into the sleeve 231. At this time, the elastic element 232 is in a compressed state, the gripper B22 slides downward and moves away from the gripper A21, and the clamp head 2 opens. Then, the clamp head 2 is hooked onto the wire. After the hooking is completed, the operating part 252 is released. The gripper B22 is pushed upward and reset under the action of the deformation of the elastic element 232, and cooperates with the gripper A21 to quickly clamp the wire. When releasing the wire, only the operating part 252 needs to be squeezed to achieve quick release.

[0050] Compared with existing high-altitude wiring pliers, the high-altitude wiring device of this utility model can automatically clamp the wire by the plier head 2 driven by the elastic element 232, without the need for the operator to manually push or pull the complicated mechanical handle, which simplifies the operation steps. Furthermore, the deformation of the elastic element 232 enables the plier head 2 to respond quickly to the operation, making the operation simpler. The wiring operation can be performed simply by squeezing the operating part 252.

[0051] Secondly, due to its simple operation, the risk of accidental clamping or incomplete clamping caused by improper operation is reduced. Simply loosening the operating part 252 will automatically reset the elastic element 232 to close the clamp head 2 and clamp the wire, greatly reducing the operation time and complexity. The operator does not need to exert force frequently.

[0052] Meanwhile, no additional locking mechanism is required, making operation simpler and faster, saving the manufacturing and maintenance costs of the locking mechanism. The constant pressure provided by the elastic element 232 can ensure that the wire is firmly clamped, reducing the risk of slippage.

[0053] The high-altitude wiring device of this utility model is more suitable for clamping lightly loaded wires or cables, such as home electrical repair, small appliance assembly, or temporary operations that require quick clamping and release, such as on-site testing and short-term wiring.

[0054] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
