Description

Technical Field

[0001] The invention belongs to the technical field of electric power fittings, and particularly relates to a drainage wire clamp convenient for locking. Background Art

[0002] The drainage wire clamp is one of the devices used in live working in the power system and plays a very important role. Most of the common drainage wire clamps currently adopt a hook form, and the main wire and the drainage wire are pressed tightly by a screw rod pushing a plug block.

[0003] For example, Chinese invention CN117394058B discloses a self-locking shooting gun drainage wire clamp. By rotating the shooting gun type operating rod to tighten the eyebolt, the wire slides into the wire clamp groove and upwardly presses against the elastic self-locking column. After the wire enters the groove, the mechanical spring pops out the self-locking column, and together with the pressing plate, forms a full-wrap structure full-press connection to the wire, so as to increase the contact surface and reduce the contact resistance; by arranging stainless steel threads in the threaded holes of the wire clamp housing, the force load is more evenly distributed on the threads, reducing the distance difference between the internal and external threads and increasing the thread contact area, greatly improving the anti-loosening ability of the wire clamp fastening.

[0004] However, the drainage wire clamps of the prior art often use a rotating bolt or screw rod to clamp the wire. During operation, an insulating operating rod is required to rotate the bolt or screw rod, and it needs to be rotated multiple times, which not only makes the operation process more cumbersome, but also easily causes fatigue of the operator's arm, resulting in poor overall usability.

Detailed implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0022] Please refer to Figures 1 to 3 As shown, the present invention is a drainage wire clamp convenient for locking, including a bottom plate 1, the bottom plate 1 is fixedly connected with a vertical plate 2, and two guide rods 301 are movably inserted. The upper ends of the two guide rods 301 are fixedly connected with a top block 3, the guide rods 301 are sleeved with springs 302, and the top block 3 is fixedly connected with a vertically arranged rack 303.

[0023] Among them, as Figure 4 and 5 shown, the upper surface of the bottom plate 1 is provided with step holes 106 that cooperate with the guide rods 301 one by one, and the lower end of the spring 302 abuts against the step surface of the step hole 106, which is beneficial to limit the position of the spring 302. The upper end of the spring 302 abuts against the lower surface of the top block 3, generating an upward pushing force on the top block 3.

[0024] The upper end of the vertical plate 2 has a hook - shaped structure 201, and the hook - shaped structure 201 is located directly above the top block 3; a clamping assembly 5 for connecting the drainage wire is fixedly connected to the side of the vertical plate 2. The clamping assembly 5 includes a lower clamping plate 501 fixedly connected to the vertical plate 2, and the lower clamping plate 501 is connected to an upper clamping plate 502 by four bolts, for clamping and fixing the drainage wire through the lower clamping plate 501 and the upper clamping plate 502.

[0025] The bottom plate 1, the vertical plate 2, and the lower clamping plate 501 are of an integral structure, formed by integral casting. Moreover, clamping grooves 503 are provided on the opposite surfaces of the lower clamping plate 501 and the upper clamping plate 502. The clamping grooves 503 can increase the contact area with the drainage wire, facilitating the clamping and limiting of the drainage wire through the clamping grooves 503.

[0026] As Figure 6 shown, a transmission shaft 401 is rotatably connected to the vertical plate 2. For example, an arc-shaped convex structure 202 is fixedly connected to the side surface of the vertical plate 2. The vertical plate 2 and the arc-shaped convex structure 202 are also of an integral structure to ensure the overall strength. An installation hole 203 matching the transmission shaft 401 is provided in the arc-shaped convex structure 202, and the transmission shaft 401 is rotatably connected to the installation hole 203 through a bearing.

[0027] The transmission shaft 401 is fixedly connected with an incomplete gear 4 meshing with the rack 303. Through grooves 101 with a clearance fit with the incomplete gear 4 are provided on both the bottom plate 1 and the vertical plate 2. The provision of the through grooves 101 can avoid the incomplete gear 4, not only reducing the overall volume but also achieving the effect of hollowing and weight reduction.

[0028] One end of the transmission shaft 401 is connected to a transmission component for driving the incomplete gear 4 to rotate, driving the top block 3 to move up and down through the rack 303. For example, when the incomplete gear 4 drives the rack 303 to move downward, a sufficient distance is left between the top block 3 and the hook-shaped structure 201, facilitating the hooking of the hook-shaped structure 201 on the power transmission wire.

[0029] Moreover, when the incomplete gear 4 is separated from the rack 303, the top block 3 is pushed upward by the spring 302, causing the top block 3 to clamp under the power transmission wire. Thus, the power transmission wire is clamped by the top block 3 and the hook-shaped structure 201. At this time, only by rotating the incomplete gear 4 and pushing the rack 303 upward can the clamping force of the top block 3 and the hook-shaped structure 201 on the power transmission wire be further increased to maintain the clamping effect.

[0030] Meanwhile, an arc-shaped limiting groove 304 is provided on the upper surface of the top block 3. The arc-shaped limiting groove 304 can not only increase the contact area with the power transmission wire but also limit the position of the power transmission wire, thus facilitating the improvement of the clamping and fixing effect on the power transmission wire.

[0031] As a preferred embodiment, the transmission assembly includes a rotating shaft 102 rotatably connected to the bottom plate 1, and a worm gear 402 fixedly connected to the transmission shaft 401; a worm 103 meshing with the worm gear 402 is fixedly connected to the upper end of the rotating shaft 102, and a circular ring 104 is connected to the upper end of the rotating shaft 102 for rotating the rotating shaft 102 through an insulating operating rod. The worm 103 drives the worm gear 402 to rotate, and then drives the incomplete gear 4 to rotate through the transmission shaft 401. Moreover, by utilizing the self-locking property of the worm and worm gear, it can be ensured that after the top block 3 and the hook-shaped structure 201 clamp the power transmission wire, the rack 303 cannot move downward, thereby ensuring the clamping and fixing of the power transmission guide wire and improving the overall reliability.

[0032] The working principle of this application is as follows: The bottom plate 1 is provided with a threaded hole 105, and the upper end of the insulating operating rod is connected with a stud. By connecting the stud at the upper end of the insulating operating rod with the threaded hole 105, the position adjustment operation of the drainage wire clamp can be realized through the insulating operating rod.

[0033] Specifically, the drainage wire clamp is lifted to the position of the power transmission wire through the insulating operating rod, and the hook-shaped structure 201 is hooked on the power transmission wire. At this time, the meshing position of the incomplete gear 4 and the rack 303 is as Figure 5 and 7 shown.

[0034] Another insulating operating rod is used to hook the circular ring 104 and rotate the rotating shaft 102. The worm 103 drives the worm gear 402 to rotate, and then the incomplete gear 4 drives the rack 303 to move downward. When the notch of the incomplete gear 4 rotates to the position of the rack 303, as Figure 8 and 9 shown, at this time, the incomplete gear 4 is separated from the rack 303, so that the rack 303 loses the restriction of the incomplete gear 4. The top block 3 is pushed upward by the elastic force of the spring 302, so that the top block 3 clamps under the power transmission wire, thereby clamping the power transmission wire by the top block 3 and the hook-shaped structure 201.

[0035] As Figure 10 and 11 shown, in order to ensure the clamping stability, the rotating shaft 102 is rotated in the reverse direction, the incomplete gear 4 rotates, and a force pushing the rack 303 upward is generated, thereby increasing the clamping force of the top block 3 on the power transmission wire. Due to the self-locking property of the meshing of the worm gear 402 and the worm 103, the top block 3 can maintain the clamping effect on the power transmission wire.

[0036] Since, under the action of the spring 302, the top block 3 has clamped on the power transmission wire, only a small number of turns of the rotating shaft 102 need to be rotated to achieve locking, thereby making the overall clamping process of the drainage wire clamp more convenient and effectively improving the overall usability.

[0037] As Figure 12 and 13 shown, when it is necessary to disassemble the drainage wire clamp, rotate the rotating shaft 102 to engage the incomplete gear 4 with the rack 303, and drive the rack 303 to move downward during the rotation process, and then drive the top block 3 to move downward, so as to release the clamping of the transmission wire, and finally remove the drainage wire clamp through the insulating operating rod.

[0038] Before the next use, the incomplete gear 4 can be pre-rotated to the critical position separated from the rack 303, as Figure 5 and 7 shown, so that during the installation operation, only a slight rotation of the rotating shaft 102 is required to separate the incomplete gear 4 from the rack 303, thereby reducing the operation time of the operator's arm in the lifted state, avoiding fatigue of the operator's arm, and thus improving the overall operation convenience.
