Description

Technical Field

[0001] The utility model relates to the technical field of live working tools, in particular to a hook-type live working line clamp. Background Art

[0002] In modern industry and power engineering, live working refers to the maintenance and repair of electrical equipment without cutting off the power supply. This operation method is usually used for high-voltage power lines, substations and related electrical facilities to reduce power outage time, improve work efficiency and ensure the continuity of power supply. Therefore, the safety and reliability of live working technology are particularly important.

[0003] As a key tool for live working, the live working line clamp is mainly used to provide a safe working platform and electrical isolation for workers in high-voltage power lines. Its design aims to ensure that when carrying out live working, the staff can safely connect, fix and operate cables or electrical equipment, while effectively preventing the risks of accidental short circuit or electric shock.

[0004] In the prior art, a patent with the publication number CN216959167U discloses a self-locking shooting gun S-type line clamp. In the design of this line clamp, a right line clamp groove and a left line clamp groove are respectively formed. The left line clamp groove is used to fix the main wire, while the right line clamp groove is used to fix the lead wire. However, since the orientations of the right line clamp groove and the left line clamp groove are the same, the choice of wiring direction is restricted, resulting in the inability to flexibly adjust the wiring direction in actual use, thus affecting the versatility and practicability of the line clamp and being unable to meet the requirements in specific scenarios.

[0030] Embodiment 1:

[0031] As Figures 1 to 6 shown, this embodiment provides a hook-type live working line clamp, including a main seat body 1. The main seat body 1 includes a hook portion 10. The hook portion 10 is provided with a first clamping surface 100 facing the clamping block 2. Along the end of the hook of the outer wall of the hook portion 10 away from the first clamping surface 100, a reinforcing rib is provided to enhance the strength of the hook portion 10. A clamping block 2 is slidably arranged on the main seat body 1. The clamping block 2 is provided with a second clamping surface 20 facing the first clamping surface 100. The first clamping surface 100 and the second clamping surface 20 form a main wire clamping groove 3, which can adapt to different specifications and types of wires, and also enhances the clamping stability of the main wire, reduces the risk of loosening caused by operation vibration or external force, and improves safety.

[0032] A clamping plate 4 is provided on the back of the main seat body 1. The four corners of the clamping plate 4 are connected to the main seat body 1 through bolt structures, making the installation and disassembly of the clamping plate 4 more convenient. On one side of the clamping plate 4 facing the back of the main seat body 1, a first clamping portion 40 is provided. On the back of the main seat body 1 facing the first clamping portion 40, a second clamping portion 11 is provided. The first clamping portion 40 and the second clamping portion 11 form a cross-shaped lead clamping groove 400, and the lead clamping groove 400 penetrates the corresponding clamping portion. By adopting the cross-shaped lead clamping groove 400, the clamping ability in the vertical and horizontal directions perpendicular to the main lead for the lead is provided, and the operator can flexibly adjust the fixing direction of the lead according to needs, avoiding practical problems caused by the limitation of the wiring direction.

[0033] Both clamping surfaces of the lead clamping groove 400 are arc-shaped surfaces or V-shaped surfaces; of course, it can also be that one of the two clamping surfaces of the lead clamping groove 400 is an arc-shaped surface and the other is a V-shaped surface. Among them, both the arc-shaped surface and the V-shaped surface can evenly distribute the pressure acting on the wire during the clamping process, avoiding wire damage or deformation caused by excessive local pressure and enhancing the stability of the clamping.

[0034] It should be understood that the same is true for the first clamping surface 100 and the second clamping surface 20.

[0035] Furthermore, a handle frame 5 is also included. The handle frame 5 is square, and one side of it is clamped in the lead clamping groove 400, providing a comfortable and stable grasping area, enabling the operator to easily hold and manipulate the wire clamp during live working and reducing the fatigue during operation.

[0036] Secondly, insulating sleeves 50 are wrapped around two opposite sides of the handle frame 5.

[0037] The four corners of the clamping plate 4 are connected to the main seat body 1 through bolt structures, which can withstand greater external forces and enhance the stability of the overall structure. The bolt structure includes two first bolt connection structures 60 located on one side close to the hook portion 10 and two second bolt connection structures 61 on the other side. The first bolt connection structure 60 includes a threaded hole 600 provided on the back of the main seat body 1, a first through hole 601 provided on the clamping plate 4, and a first bolt 602. The first bolt 602 passes through the first through hole 601 and is connected to the threaded hole 600. The second bolt connection structure 61 includes a sunken hole 610 provided on the front of the main seat body 1, a second through hole 611 provided on the clamping plate 4, a second bolt 612, and a fixing nut 613. The second bolt 612 passes through the sunken hole 610 and the second through hole 611 from the front of the main seat body 1 and is connected to the fixing nut 613. The sunken hole 610 allows the head of the second bolt 612 to sink into the main seat body 1.

[0038] On one side of the main seat body 1 away from the hook part 10, a plate part 12 is provided. A threaded connection hole 120 is provided on the plate part 12. On one side of the clamping block 2 away from the hook part 10, a screw member 7 is provided. The screw member 7 is in threaded cooperation with the threaded connection hole 120, and an operation end 70 is provided thereon. By rotating the screw member 7, the clamping block 2 can be moved closer to or away from the hook part 10. The operation end 70 is hexagonal or circular and is used for cooperating with the operation rod of the injection gun.

[0039] On the screw member 7, a locking nut 8 is provided on the side close to the operation end 70. A spring washer 9 is provided on the screw member 7 between the locking nut 8 and the plate part 12. The loosening of the screw member 7 is effectively prevented by the locking nut 8 and the spring washer 9, ensuring the stability of the clamping block during use and improving the operation safety.

[0040] Further, on both sides of the main seat body 1, sliding grooves 13 are provided along the sliding direction of the clamping block 2. Corresponding to the sliding grooves 13 on the clamping block 2, sliding blocks 21 are provided. An opening 130 is provided on the upper part of the sliding groove 13 facing the front of the main seat body 1. The opening 130 allows the sliding block 21 to pass through. The sliding block 21 is assembled into the sliding groove 13 through the opening 130. The sliding grooves 13 on both sides of the main seat body 1 and the sliding blocks 21 on the clamping block 2 form a good sliding fit, enabling smooth displacement, reducing friction, and improving the operation efficiency.

[0041] Secondly, a guiding surface 131 is provided at the corner of the opening 130 and the sliding groove 13 to ensure the smooth sliding of the sliding block 21 into the sliding groove 13 and reduce the assembly difficulty. The contact surface between the sliding block 21 and the sliding groove 13 is an arc surface to ensure the smooth movement of the sliding block 21, reduce the possibility of jamming, and improve the fluency and stability of use.
