Description

Technical Field

[0001] The utility model relates to the technical field of electric power installation, and more specifically to a lead clamp for installing electric power equipment. Background Art

[0002] In the field of power equipment installation, lead clamps, as a key connection and fixing device, bear the important responsibility of ensuring that power leads are stably and safely connected to power equipment. With the continuous development of power technology, power equipment has increasingly higher requirements for the performance and reliability of lead clamps.

[0003] Chinese utility model patent CN220934412U discloses a lead clamp for installing power equipment, including a fixed frame, on which a plurality of wire grooves are provided; a clamping assembly, wherein a plurality of the clamping assemblies correspond one to one with the plurality of wire grooves, and the clamping assembly includes a screw, a rotating block, a buffer spring, a sliding block, and an arc block. In the utility model, by setting the clamping assembly, when the screw is rotated, the position of the rotating block in the limit groove can be adjusted, thereby changing the position of the buffer spring away from one end of the sliding block, facilitating the formation of a clamping effect with different forces on the lead through the arc block, while improving the clamping effect on the leads of different diameters, forming a buffering effect on the lead, and effectively avoiding damage to the lead when it fluctuates.

[0004] During the installation of power equipment, connecting cables is a crucial step, which directly affects the stability and safety of power transmission. Although traditional lead clamps can fix and connect cables, there are many inconveniences in actual use. For example, when using a C-type wire clamp to connect the main conductor and the lead wire, the main notch of the wire clamp is usually hung on the main conductor first, and then the lead wire is inserted into the lead groove of the wire clamp. When connecting the lead wire, the staff needs to pull the lead wire by hand to make the lead wire pass through the lead groove of the wire clamp. However, if the main conductor is live, there are great difficulties and safety risks in manual operation by the staff, which not only affects work efficiency, but also may increase the risk of operational errors, thereby affecting the safe operation of the power system.

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0022] Figure 1-Figure 4 It is the best embodiment of the utility model, and the following Figure 1-Figure 4 The utility model is further described.

[0023] A lead wire clamp for installing electric power equipment comprises a mounting frame 1 and a wire clamp 3 arranged inside the mounting frame 1. The mounting frame 1 is U-shaped, and the shape of the inner wall of the top thereof matches the wire clamp 3. The wire clamp 3 is provided with a main wire groove 301 and a lead wire groove 302. Push plates are provided in the main wire groove 301 and the lead wire groove 302. By screwing the fixing bolts of the wire clamp 3, the push plates in the main wire groove 301 and the lead wire groove 302 can be actuated to clamp the cables. The above structure is a structure of the prior art. The wire clamp 3 can be a C-type aluminum alloy wire clamp of the prior art with the model number ct813.

[0024] The lead clamp for installing the power equipment also includes a positioning component 2, a pushing component 4, a movable frame 5 and a limiting component 6. The positioning component 2 is arranged at the bottom of the mounting frame 1, and a positioning frame 204 is arranged on the top of the positioning component 2. The positioning frame 204 can clamp the wire clamp 3 in the mounting frame 1.

[0025] The positioning assembly 2 includes a slide groove 201, the inner side of the mounting frame 1 is provided with the slide groove 201, a guide rod 202 is fixedly installed inside the slide groove 201, a sliding plate 203 is slidably connected to the surface of the guide rod 202, and a positioning frame 204 is fixedly installed on the side of the sliding plate 203. A bearing seat 205 is fixedly installed at the bottom of the positioning frame 204, a threaded rod 206 is rotatably installed inside the bearing seat 205, the threaded rod 206 is threadedly connected to the bottom wall of the mounting frame 1, and a knob 207 is fixedly installed at the bottom of the threaded rod 206.

[0026] In this embodiment, when the positioning frame 204 moves up and down, it will drive the sliding plate 203 to slide in the sliding groove 201, and cooperate with the guide rod 202 to play a guiding and limiting role. In this embodiment, the threaded rod 206 can be driven to rotate by rotating the knob 207 using the rotating tool 7, so that the threaded rod 206 drives the positioning frame 204 to move up and down, so that the clamping gap of the mounting frame 1 can be adjusted, so that the present application can adapt to wire clamps 3 of different sizes.

[0027] The pushing assembly 4 is arranged on the side of the mounting frame 1 and is arranged near the lead groove 302 of the wire clamp 3. The pushing assembly 4 includes a limiting rod 401. The limiting rod 401 is fixedly installed on the side of the mounting frame 1. A fixing frame 402 is fixedly installed on the side of the limiting rod 401 away from the mounting frame 1. A threaded rod 2 403 is rotatably installed on the side of the mounting frame 1 and below the limiting rod 401. A knob 2 404 is fixedly installed on the side of the threaded rod 2 403 away from the mounting frame 1. The threaded rod 2 403 is rotatably connected to the fixing frame 402. The external thread of the threaded rod 2 403 is connected to a movable frame 5. The movable frame 5 is slidably connected to the limiting rod 401. A limiting groove is provided at the upper end of the movable frame 5, and the limiting assembly 6 is arranged in the limiting groove of the movable frame 5.

[0028] In this embodiment, using the rotating tool 7 to rotate the knob 2 404 can drive the threaded rod 2 403 to rotate. Under the interaction between the external thread of the threaded rod 2 403 and the internal thread of the movable frame 5, the movable frame 5 can move left and right, and the lead wire on the inner side of the movable frame 5 is sent to the wire clamp 3 in the mounting frame 1, so that the lead wire is inserted into the lead groove 302 of the wire clamp 3. In addition, in the process of the movable frame 5 moving left and right, the movable frame 5 can slide on the surface of the limit rod 401, thereby playing a role of limiting and guiding.

[0029] The limiting component 6 includes a threaded rod 3 601, a threaded hole is provided on the side of the movable frame 5, and the threaded rod 3 601 is connected to the inner thread of the threaded hole, a knob 3 602 is fixedly installed on the side of the threaded rod 3 601 away from the movable frame 5, a clamping plate 603 is provided on the side of the threaded rod 3 601, a bearing seat 2 604 is fixedly installed on the side of the clamping plate 603, and the threaded rod 3 601 is rotatably installed inside the bearing seat 2 604.

[0030] In this embodiment, the use of the rotating tool 7 to rotate the knob three 602 can drive the threaded rod three 601 to rotate, so that the threaded rod three 601 can drive the clamping plate 603 to move forward and backward, so as to clamp and fix the leads of different sizes.

[0031] The side of the clamping plate 603 is bonded with a buffer pad 605, which is made of polychloroprene rubber material. It can not only play a buffering role in the process of clamping the cable to avoid excessive clamping force to damage the lead wire, but also can increase the friction between the limit assembly 6 and the lead wire to prevent the lead wire from loosening during movement.

[0032] The mounting frame 1, positioning assembly 2, pushing assembly 4, movable frame 5 and limiting assembly 6 are all made of insulating materials. With the help of this application, the staff connects the wire clamp 3 with the main conductor and the lead wire to avoid manual contact with the wire clamp 3 and the lead wire, thereby ensuring the safety of the staff's operation.

[0033] Knob 1 207, knob 2 404 and knob 3 602 all adopt a hexagonal knob structure, which is convenient for matching with the rotating tool 7. The rotating tool 7 can be an electric wrench, and the rotating tool 7 adopts an insulating handle.

[0034] The working principle and use process of the utility model are as follows: when in use, first put the wire clamp 3 into the mounting frame 1, then rotate the knob 207 to make the positioning frame 204 move upward, fix the wire clamp 3 in the mounting frame 1, then put the lead wire into the limiting groove of the movable frame 5, and the end of the lead wire is arranged toward the wire clamp 3, and the end of the lead wire is exposed outside the limiting groove to be connected with the wire clamp 3, then rotate the knob 3 602 by rotating the tool 7, so that the threaded rod 3 601 drives the clamping plate 603 to move inward together, and clamps and fixes the lead wire; then hang the upper main wire groove 301 of the wire clamp 3 on the outside of the main wire through the mounting frame 1, and then rotate the knob 3 602 to make the threaded rod 3 601 drive the clamping plate 603 to move inward together, and clamp and fix ... The tool 7 rotates the knob two 404 to drive the threaded rod two 403 to rotate. Under the interaction of the external thread of the threaded rod two 403 and the internal thread of the movable frame 5, the movable frame 5 drives the lead wire to move in the direction of the wire clamp 3, thereby sending the lead wire on the inner side of the movable frame 5 into the lead wire groove 302 at the lower part of the wire clamp 3. Finally, the fixing bolt of the wire clamp 3 is rotated by rotating the tool 7 to make the push plate on the inner side of the wire clamp 3 move, and the main wire and the lead wire are fixed in the two grooves of the wire clamp 3, thereby completing the connection of the two cables; thereafter, the knob three 602 and the knob one 207 are turned in turn to loosen the movable frame 5 and the mounting frame 1 from the lead wire and the wire clamp 3 respectively, and the device can be removed.

[0035] When the wire clamp 3 and the lead wire need to be removed from the main wire, the operation can also be performed with the aid of the utility model. The operation method can be inferred from the above description and will not be repeated here.
