Description

Technical Field

[0001] This utility model relates to the field of power detection clamping, specifically a power detection clamping device. Background Technology

[0002] Power wires and cables are wire products used to transmit electrical energy, information and realize electromagnetic energy conversion. In a broad sense, wires and cables are also simply referred to as cables. In a narrow sense, cables refer to insulated cables, which can be defined as one or more insulated conductors, as well as their respective sheaths, overall protective layers and outer protective layers. Cables may also have additional uninsulated conductors.

[0003] A search of patent publication number CN222261950U reveals a power testing clamping device, comprising a testing box. The front of the testing box has a strip-shaped groove, and sliding plates are slidably connected to both sides of the groove. This utility model relates to the field of power testing technology. This power testing clamping device, by rotating a first threaded rod, causes the clamping plate to move downwards, clamping the cable on an L-shaped plate. This allows for convenient clamping of two cables onto two L-shaped plates, eliminating the need for continuous manual clamping by power personnel. Rotating a rotating rod then drives a first bevel gear, which in turn drives a second threaded rod via a second bevel gear. The second threaded rod, through a threaded sleeve and sliding plates, moves the L-shaped plates towards the center, thereby pulling the two cables towards the center for testing. This significantly frees up the hands of power personnel for testing, improving efficiency.

[0004] The existing clamping structure uses a threaded rod knob to move the clamping plate downwards to clamp the cable on the L-shaped plate. However, in actual operation, it is sometimes necessary to rotate many times to clamp and fix the cable. In addition, the clamping force of this clamping structure is difficult to control. Over-clamping can easily damage the cable, while insufficient clamping force will lead to unstable clamping. Secondly, for the detection of two cables being pulled towards the middle by two L-shaped plates, the distance between the two cables is adjusted by turning, which is time-consuming and labor-intensive, greatly reducing the detection efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4 In the embodiment of the present utility model, a power detection clamping device includes a base 1. A strip-shaped groove 11 is formed in the front part of the base 1. It is characterized in that a sliding rod 2 is arranged inside the base 1. The sliding rod 2 is arranged parallel to the strip-shaped groove 11, and both ends of the sliding rod 2 are fixedly connected to the two opposite inner walls of the base 1 respectively. Two clamping components 4 are slidably connected in the length direction of the strip-shaped groove 11 for clamping two cables respectively; Two sliding seat components 3 are slidably connected in the length direction of the sliding rod 2. The sliding seat components 3 are fixedly connected to the back of the clamping components 4 by welding, and are used to limit or release the sliding of the clamping components 4 to facilitate controlling the fixed distance between the two clamping components 4.

[0019] In this embodiment: By setting the clamping component 4, the cable can be quickly clamped and fixed. The spring is used to pre-clamp the cable, and then the second extrusion block 411 is pushed by air pressure to apply a clamping force to the cable, thereby forming a quick clamping of the cable and ensuring firm clamping; Secondly, by setting the sliding seat component 3 on the back end face of the clamping component 4, the sliding seat component 3 also uses a pneumatic method to push the first extrusion block 305 to press against the sliding rod 2, restricting the movement of the clamping component 4, and thus facilitating controlling the fixed distance between the two clamping components 4.

[0020] Please pay special attention to Figures 1-4 The clamping component 4 includes a base frame 401. The base frame 401 is in a "U" - shaped structure. A guiding rod 402 is arranged inside the base frame 401. Both ends of the guiding rod 402 are fixedly connected to the upper and lower inner walls of the base frame 401 respectively. A movable block 403 is slidably connected in the length direction of the guiding rod 402; A cylinder 404 is connected to the top of the movable block 403. The cylinder 404 movably penetrates through the top of the base frame 401. A handle 406 is integrally formed at the upper end of the cylinder 404. And a spring 405 is sleeved on the outer wall of the lower end of the cylinder 404. The spring 405 is located between the top inner wall of the base frame 401 and the movable block 403; The clamping component 4 further includes a guiding groove 407 opened at the bottom of the movable block 403. A second air groove 408 is opened at the top of the guiding groove 407. A second piston 409 is installed inside the second air groove 408. A second connecting rod 410 is connected to the lower end of the second piston 409. A second extrusion block 411 is connected to the lower end of the second connecting rod 410; The cylinder 404 and the top of the base frame 401 are movably and penetratingly connected; The second air groove 408 is communicated with the cylinder 404. The top of the cylinder 404 is connected to a second air pipe 6 through a conduit joint. The second extrusion block 411 is located inside the guiding groove 407; One end of the slide assembly 3 is connected to the first air pipe 5 via a conduit connector. Both the first air pipe 5 and the second air pipe 6 are equipped with an air pumping system.

[0021] In this embodiment: Since there are various cable specifications and sizes, when it is necessary to clamp and fix the cable, the movable block 403 is lifted by the handle 406, and then the cable is placed between the lower end of the base frame 401 and the movable block 403. After releasing the handle 406, the movable block 403 is pressed down by the elastic force of the spring 405, so that the movable block 403 presses down on the cable, forming a pre-clamping of the cable. Next, air is supplied to the second air pipe 6 through the air pumping system. The air enters the second air groove 408 through the cylinder 404 and pushes the second piston 409 downward, so that the second extrusion block 411 forms an extrusion force on the cable, thereby applying a clamping force to the cable to ensure that the cable is firmly clamped and fixed. Conversely, when there is no air, the second extrusion block 411 is in a loose state and will not form a clamping effect on the cable. The pre-clamping of the cable can be released by lifting the movable block 403.

[0022] It should be noted that the existing pneumatic system in this solution, the existing pneumatic clamping system, mainly consists of an air source, pneumatic actuators such as cylinders, control elements such as solenoid valves and throttle valves, auxiliary elements such as air pipes and silencers, together with the clamping assembly 4 and the slide assembly 3 in this solution to form a pneumatic clamping system, which will not be described in detail here.

[0023] Please refer to this carefully. Figures 1-4 The slide assembly 3 includes a seat 301, one end of which is slidably connected to the slide rod 2, and the other end of the seat 301 is provided with a first air groove 302. A first piston 303 is installed inside the first air groove 302, and a first connecting rod 304 is connected to one end of the first piston 303. A first extrusion block 305 is connected to the end of the first connecting rod 304 away from the first piston 303. The side of the first pressing block 305 facing the slide bar 2 is a concave arc surface, and the concave arc surface of the first pressing block 305 matches the outer contour of the slide bar 2. The contact surface between the first pressing block 305 and the slide bar 2 is a rough surface.

[0024] In this embodiment: when it is necessary to restrict the movement of the clamping assembly 4, air is supplied to the first air pipe 5 through the air pumping system. The gas enters the first air groove 302 and pushes the first piston 303 to move to one side of the slide rod 2. This pushes the first pressing block 305 to press against the slide rod 2, restricting the sliding of the seat 301 and the slide rod 2, thus restricting the movement of the clamping assembly 4. This makes it easier to control the fixed distance between the two clamping assemblies 4.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
