Description

Technical Field

[0001] The present invention relates to the technical field of power maintenance, and particularly to an automatic locking type anti-loosening grounding wire clamp. Background Art

[0002] The grounding wire clamp is a key component used to connect the grounding conductor in the power system, electrical equipment and lightning protection project. Its main function is to reliably connect the equipment or line to the grounding network, ensure the safe discharge of fault current, lightning current or static electricity, and guarantee the safety of personnel and equipment. During the power maintenance operation, the line is often connected to the grounding wire clamp after power-off to avoid residual electricity or sudden power-off in the wire, thereby ensuring the safety of the maintenance personnel during the maintenance process.

[0003] For example, a throwing and pulling type grounding wire clamp disclosed in the publication number CN214378924U includes a first clamping handle, a second clamping handle, and also includes a first rotating shaft, a tension spring, a movable clamping plate, a second rotating shaft, a support pin and a support clamping block; the ends of the first clamping handle and the second clamping handle are hinged through the first rotating shaft; the tension spring is arranged between the first clamping handle and the second clamping handle; the movable clamping plate is arranged on the first clamping handle, one end of the movable clamping plate is rotatably connected to the first clamping handle through the second rotating shaft, and the first clamping handle and the second clamping handle are always opened to form a hook shape. When in use, it can be thrown onto the transmission wire by using an insulating wire. After hooking the transmission wire, the connection and disconnection with the high-voltage wire can be realized by pulling the flexible connecting wire, and the operation is simple and convenient, reducing the labor intensity of the maintenance personnel.

[0004] Another example is a grounding wire clamp for convenient hanging and removing of the grounding wire disclosed in the publication number CN220731809U, which includes an operating rod. A sliding cavity is arranged in the operating rod, and a grounding body is slidably arranged in the sliding cavity. A hook is fixedly arranged at the top end of the grounding body, and the bottom of the grounding body is connected to the grounding wire. An adjusting section is fixedly arranged between the grounding body and the grounding wire. A clamping plate detachably connected to the operating rod is arranged above the adjusting section, and an adjusting member is arranged on the right side of the adjusting section. The adjusting member includes a rotating gear, and both ends of the rotating gear are respectively hinged to the clamping plate and the operating rod; an adjusting tooth meshing with the rotating gear is arranged on the right end face of the adjusting section. By adjusting the adjusting member to adjust the adjusting section, the axial position of the grounding body in the operating rod can be adjusted, and then the operation of hanging and removing the grounding wire can be conveniently controlled by controlling the hook.

[0005] In the prior art such as the above patents, the wire clamp has the advantages of simple and convenient operation and reduced labor intensity of the maintenance personnel. However, the simple setting of the clamping assembly may lead to unstable clamping, and then the phenomenon of poor contact with the wire may occur. In the actual use of the grounding wire clamp, the operator needs to rotate the rotating rod threadedly installed on the mounting bracket to push the clamping block to clamp the wire to achieve installation. During the operation, the rotating rod needs to be rotated many circles to achieve clamping. Although the clamping is stable, the operation is too time-consuming. Summary of the Invention

[0006] The object of the present invention is to provide an automatic locking type anti-loosening grounding wire clamp to solve the deficiency in the prior art that a large number of turns of the rotating rod are required during the installation process to achieve clamping.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Please refer to Figures 1-7 , an automatic locking and anti-loosening grounding wire clamp provided by an embodiment of the present invention includes a hook-shaped chuck 1, a rotating frame 2, a first arc-shaped clamp 3, a second arc-shaped clamp 4 and a slide bar 5. Among them, the hook-shaped chuck 1 is generally in an inverted "J" shape, specifically composed of a straight rod portion and a hook portion connected to each other. The rotating frame 2 is rotatably connected near the hook portion of the hook-shaped chuck 1. The rotating frame 2 includes two struts with an included angle. The first arc-shaped clamp 3 is fixedly connected to the rotating frame 2. The first arc-shaped clamp 3 is composed of a linear array of a plurality of first clamping pieces 31 with a curved side surface. The second arc-shaped clamp 4 is horizontally slidably connected to the hook-shaped chuck 1. The second arc-shaped clamp 4 is composed of a linear array of a plurality of second clamping pieces 41 with a curved side surface. The first clamping piece 31 and the second clamping piece 41 are arranged alternately. During the process of the first arc-shaped clamp 3 rotating along the mounting seat, each first clamping piece 31 can just pass through the gap between two second clamping pieces 41 (refer to Figure 7 ). A first elastic member 42 is provided between the second arc-shaped clamp 4 and the hook-shaped chuck 1. The first arc-shaped clamp 3 has two limit working positions during the rotation process on the hook-shaped chuck 1 through the rotating frame 2, namely the preparatory working position and the clamping working position. When the first arc-shaped clamp 3 is in the preparatory working position, the opening of the first arc-shaped clamp 3 faces downward; when the first arc-shaped clamp 3 is in the clamping working position, the opening of the first arc-shaped clamp 3 faces the opening of the second arc-shaped clamp 4.

[0030] A guide slot is provided on one of the supporting rods of the rotating frame 2, and the slide bar 5 is movably arranged in the guide slot, so that the slide bar 5 can slide relative to the rotating frame 2 through the guide slot, but the slide bar 5 will not completely leave the guide slot, and a compression spring 511 is installed in the guide slot, one end of the compression spring 511 abuts against the bottom of the guide slot, and the other end abuts against the end of the slide bar 5. Of course, the compression spring 511 can be replaced by other first elastic members 42, such as tension springs, air springs, etc., and it is required that the elastic force of the first elastic member 42 is released to drive the slide bar 5 to slide outside the guide slot.

[0031] The hook-shaped clamp 1 is provided with an arc-shaped slide groove 53 for use with the slide rod 5. The arc-shaped slide groove 53 is below the mouth of the locking groove 52. When the first arc-shaped clamp 3 is rotated and switched from the preparation position to the clamping position, the rotating frame 2 and the slide rod 5 rotate together with the first arc-shaped member. When it rotates to the vicinity of the clamping position, a sliding contact occurs between the end of the slide rod 5 away from the compression spring 511 and the arc-shaped slide groove 53, so that the slide rod 5 slides into the guide groove and squeezes the compression spring 511. The compression spring 511 accumulates energy until the first arc-shaped clamp 3 rotates to the clamping position. At this time, the slide rod 5 is opposite to the locking groove 52. The elastic potential energy accumulated in the compression spring 511 is released, so that the slide rod 5 is quickly inserted into the locking groove 52, thereby locking the first arc-shaped clamp 3 in the clamping position, and the position of the rotating clamp is also fixed.

[0032] A tension spring 421 is installed in the hook-shaped clamp 1, one end of the tension spring 421 is fixedly connected to the second arc clamp 4, and the other end is fixedly connected to the hook-shaped clamp 1. Of course, the tension spring 421 can be replaced by other second elastic members 51, such as compression springs, air springs, etc., and it is required that when the elastic force of the second elastic member 51 is released, the second arc clamp 4 is driven to slide in a direction away from the first arc clamp 3.

[0033] The transmission member 6 includes a rotating sleeve 61 rotatably mounted on the hook-shaped clamp 1, one end of the rotating sleeve 61 is slidably connected to the first connecting rod 62, and the other end is slidably connected to the second connecting rod 63. A force transmission block 64 is slidably installed in the lock groove 52 along the depth direction. The first connecting rod 62 is rotatably connected to the second arc clamp 4, and the second connecting rod 63 is rotatably connected to the force transmission block 64.

[0034] When the first arc-shaped clamp 3 is in the clamping station, the sliding rod 5 is embedded in the locking groove 52. During the process of the compression spring 511 releasing elastic potential energy, the sliding rod 5 slides inward and pushes the force transmission block 64 to slide into the locking groove 52 along the horizontal direction. When the force transmission block 64 moves and the rotating sleeve 61 is rotatably installed, through the first connecting rod and the second connecting rod 63, the force is transmitted to push the second arc-shaped clamp 4 to move. At this time, the first connecting rod 62 and the second connecting rod 63 slide away from the rotating sleeve 61. Since the first connecting rod 62 is rotatably connected to the second arc-shaped clamp 4 and the second arc-shaped clamp 4 is horizontally slidably installed, the second arc-shaped clamp 4 slides along the horizontal direction, moves towards the direction close to the wire and locks the wire.

[0035] It further includes a reset assembly 7. The reset assembly 7 includes an unlocking member 72 and a third elastic member 71. The unlocking member 72 includes a rope 721 and a push rod 722. The push rod 722 is vertically slidably installed at the lower end of the straight rod part of the hook-shaped chuck 1. One end of the rope 721 passes through the guide groove and is fixedly connected to the end of the sliding rod 5 located in the guide groove. The other end of the rope 721 is fixedly connected to the end of the push rod 722 located in the hook-shaped chuck 1. Two fixed pulleys for guiding the sliding of the rope 721 are rotatably installed in the hook-shaped chuck 1. The two fixed pulleys are arranged vertically. The rope 721 respectively passes around the two fixed pulleys. When the push rod 722 moves upward, it drives the rope 721 to move and pulls the sliding rod 5 to slide into the guide groove. A grip 8 is fixedly connected to the bottom of the push rod 722. Push the grip 8 upward, the grip 8 drives the push rod 722 to slide along the sliding installation direction of the push rod 722. The sliding of the push rod 722 drives the rope 721 to move. The rope 721 pulls the sliding rod 5 to move along the guide groove until the sliding rod 5 moves to a position where it is no longer embedded in the locking groove 52. It is worth mentioning that during the reset process of the sliding rod 5, the elastic potential energy of the tension spring 421 is released. During the movement of the sliding rod 5, the tension spring 421 drives the second arc-shaped clamp 4 to move and reset.

[0036] A third elastic member 71 is provided in the hook-shaped chuck 1. The third elastic member 71 includes an arc-shaped sliding sleeve 711, an arc-shaped rod 712 and an arc-shaped spring 713. The arc-shaped sliding sleeve 711 is fixedly installed near the hook part of the hook-shaped chuck 1. The arc-shaped rod 712 is slidably installed in the arc-shaped sliding sleeve 711. One end of the arc-shaped spring 713 abuts against the arc-shaped sliding sleeve 711, and the other end of the arc-shaped spring 713 abuts against the arc-shaped rod 712. The end of the arc-shaped rod 712 located outside the arc-shaped sliding sleeve 711 is the abutting end.

[0037] The elastic potential energy of the arc spring 713 inside the arc sliding sleeve 711 is released, driving the arc rod 712 to slide. The arc rod 712 drives the abutting end to move, and the abutting end pushes the side wall of the first arc clip 3 to rotate along the rotation direction of the rotating seat until the first arc clip 3 rotates to the preparatory position. Of course, the arc spring 713 can be replaced by other elastic components, such as compression springs, air springs, etc. It is required that when the elastic force of this elastic component is released, it drives the arc rod 712 to slide away from the arc sliding sleeve 711.

[0038] Working principle: During use, the first arc clip 3 is in a state with the opening facing vertically downward, that is, the preparatory position. The operator holds the grip 8 and moves the hook-shaped clip head 1, so that the first arc clip 3 approaches the wire downward from above the wire until the wire is embedded in the opening of the first arc clip 3. At this time, the operator pulls the grip 8 downward, and the first arc clip 3 rotates together with the rotating frame 2 to the clamping position under the obstruction of the wire. The rotating frame 2 drives the slide bar 5 to rotate together. During the rotation process, on the one hand, the first clip piece 31 passes through the gap formed by the second arc clip pieces. On the other hand, the side wall of the support rod fixedly connected to the first arc clip 3 pushes the abutting end and drives the arc rod 712 to slide along the arc sliding sleeve 711, and the arc spring 713 is energy-stored. On the third hand, when approaching the clamping position, the end of the slide bar 5 far from the compression spring 511 makes a sliding contact with the arc-shaped chute 53, causing the slide bar 5 to slide into the guide groove and compress the compression spring 511, and the compression spring 511 is energy-stored.

[0039] Then, when the rotating frame 2 rotates until the slide bar 5 is aligned with the locking groove 52, that is, the first arc clip 3 moves to the clamping position, the compression spring 511 releases energy, pushes the slide bar 5 to slide, the slide bar 5 is embedded in the locking groove 52, and pushes the force transmission block 64 to slide along the horizontal direction. The force transmission block 64 drives the second arc clip 4 to move towards the first arc clip 3 under the cooperation of the transmission member 6, so that the second arc clip 4 and the first arc clip 3 cooperate to clamp and lock the wire. At this time, the tension spring 421 is in an energy-stored state, and the installation operation of the grounding wire clip on the wire is completed.

[0040] After the electric power maintenance operation is completed, it is necessary to remove the grounding wire clip. Push the grip 8 upward, so that the push rod 722 moves upward. The push rod 722 pulls the slide bar 5 to move along the guide groove and withdraw from the locking groove 52 through the rope 721. At the same time, after the force transmission block 64 loses the extrusion of the slide bar 5, the elastic potential energy of the tension spring 421 is released, driving the second arc clip 4 to move away from the wire and reset, and the force transmission block 64 also slides to a position close to the notch of the locking groove 52.

[0041] After the sliding rod 5 exits the locking groove 52, the elastic potential energy of the arc-shaped spring 713 in the arc-shaped sliding sleeve 711 immediately begins to be released, driving the arc-shaped rod 712 to slide. The arc-shaped rod 712 drives the abutting end to move, and the abutting end pushes the side wall of the first arc-shaped clamp 3 to rotate along the rotation direction of the rotating seat until the first arc-shaped clamp 3 rotates back to the preparatory position with the rotating frame 2. Then, continue to push the grip 8 upward until the wire leaves the first arc-shaped clamp 3, remove the grounding wire clamp, and the operation ends.

[0042] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
