Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, and in particular to a high-voltage cable testing device. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals, typically composed of several or groups of conductors. A cable is made of one or more insulated conductors and an outer insulating protective layer, transmitting electricity or information from one point to another. It is usually a rope-like cable made of several or groups of conductors twisted together. Because cables serve as a conductive carrier, they are exposed to wind and rain for extended periods outdoors. If damage or breakage occurs due to quality issues, it can easily cause significant personal injury and property damage. Therefore, for safety reasons, cables need to undergo quality testing before leaving the factory.

[0003] Currently, quality inspection devices in cable production typically require the cable to be securely fixed during inspection. Traditionally, this process relies on threaded rods or electric actuators. However, with increased usage time, threaded rods are prone to stripping, leading to instability in clamping and affecting the accuracy and reliability of the inspection. Electric actuators, on the other hand, often require four or more actuators to simultaneously fix both ends of the cable, increasing both equipment complexity and production costs. Therefore, a high-voltage cable testing and inspection device is urgently needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-voltage cable testing and inspection device.

[0007] The clamping mechanism includes U-shaped fixing frames at both ends of the top of the base. Fixing cylinders are fixed to the top of both sides of the inner wall of the U-shaped fixing frames. Two arc-shaped clamping plates are provided on both sides of the inner wall of each fixing cylinder. Fixing rods are fixed to the opposite sides of the two arc-shaped clamping plates.

Racks are provided on the adjacent sides of the two fixing blocks, and the two racks mesh with the gears. The two fixing blocks are staggered.

The other ends of the two connecting rods are fixedly connected to the outer walls of the corresponding fixing rods. Through the gears, the two arc-shaped clamping plates can be moved away from or closer together to clamp and fix the cable.

[0008] Preferably, the inner wall of the through groove is provided with trapezoidal grooves at the top and bottom, and trapezoidal sliders are slidably provided inside the two trapezoidal grooves. The two trapezoidal sliders are respectively fixedly connected to the corresponding fixed blocks.

[0009] Preferably, a first motor is installed at the bottom of the two U-shaped fixing frames on their opposite sides, and the output shafts of the two first motors are respectively fixedly connected to one end of the corresponding rotating rod.

[0010] Preferably, the top two ends of the base are provided with limiting mounting grooves, and the inner walls of the two limiting mounting grooves are rotatably connected to the same bidirectional screw. The sides of the two limiting mounting grooves that are close to each other are provided with holes for the bidirectional screw to pass through. The outer walls of both ends of the bidirectional screw are slidably provided with matching sliding blocks with sliding sleeves, and the sliding blocks with sliding sleeves are adapted to the limiting mounting grooves. The tops of the two sliding blocks with sliding sleeves are respectively fixedly connected to the bottoms of the two U-shaped fixing frames. The bidirectional screw can drive the two U-shaped fixing frames to move away from each other, and realize the tensile testing of the cable.

[0011] Preferably, a second motor is installed at one end of the base, and the output shaft of the second motor is fixedly connected to one end of a bidirectional lead screw.

[0012] Preferably, the pressing mechanism includes a mounting bracket fixed to the top of the base, and a pressure plate is provided on the top of the inner wall of the mounting bracket. The pressure plate can press down on the cable to further test its compressive strength.

[0013] Preferably, an electric push rod is mounted on the top of the mounting bracket, and the output shaft of the electric push rod is fixedly connected to the top of the pressure plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Due to the adoption of a clamping mechanism, the first motor drives the rotating rod to rotate, and then the rack and gear mesh to bring the two arc-shaped clamping plates close to each other to clamp and fix the outer wall of the cable. This achieves clamping and fixing of both ends of the cable through a separate drive, saving the manufacturing cost of the detection device, potentially reducing equipment wear, and thus reducing the cost of later maintenance and replacement.

The two fixing blocks 208 are equipped with racks 209 on their sides that are close to each other. The two racks 209 mesh with the gear 205 respectively. The two fixing blocks 208 are staggered. Two connecting rods 212 are fixed at both ends of the sides of the two fixing blocks 208 that are far apart from each other. The other ends of the two connecting rods 212 are fixedly connected to the outer wall of the corresponding fixing rod 211 respectively. Through the gear 205, the two arc-shaped clamping plates 210 can be driven to move away from each other or move closer to each other to clamp and fix the cable 4.

[0024] In this utility model, trapezoidal grooves 206 are provided at the top and bottom of the inner wall of the through groove 203, and trapezoidal sliders 207 are slidably provided inside the two trapezoidal grooves 206. The two trapezoidal sliders 207 are respectively fixedly connected to the corresponding fixing blocks 208.

[0025] In this utility model, a first motor 202 is installed on the bottom of the two U-shaped fixing frames 2 on the side away from each other, and the output shafts of the two first motors 202 are respectively fixedly connected to one end of the corresponding rotating rod 204.

[0026] In this utility model, the top two ends of the base 1 are provided with limiting mounting grooves 101. The inner walls of the two limiting mounting grooves 101 are rotatably connected to the same bidirectional screw 5. The side of the two limiting mounting grooves 101 that is close to each other is provided with a hole for the bidirectional screw 5 to pass through. The outer walls of both ends of the bidirectional screw 5 are slidably provided with matching sliding blocks 502. The sliding blocks 502 are adapted to the limiting mounting grooves 101. The limiting mounting grooves 101 can limit the sliding blocks 502. The tops of the two sliding blocks 502 are respectively fixedly connected to the bottoms of the two U-shaped fixing frames 2. The bidirectional screw 5 can drive the two U-shaped fixing frames 2 to move away from each other and realize the tensile test of the cable 4.

[0027] In this utility model, a second motor 501 is installed at one end of the base 1, and the output shaft of the second motor 501 is fixedly connected to one end of the bidirectional lead screw 5.

[0028] In this utility model, the pressing mechanism includes a mounting bracket 3 fixed to the top of the base 1. The top of the inner wall of the mounting bracket 3 is provided with a pressure plate 302, which can press down on the cable 4 to further test its compressive strength.

[0029] In this utility model, an electric push rod 301 is installed on the top of the mounting bracket 3, and the output shaft of the electric push rod 301 is fixedly connected to the top of the pressure plate 302.

[0030] Working principle: In use, one end of cable 4 is passed through one of the fixed cylinders 201, and the other end of cable 4 is passed through the other end of the fixed cylinder 201. The two ends of cable 4 are respectively positioned between the arc-shaped clamping plates 210. Then, the first motor 202 is activated, which drives the rotating rod 204 to rotate and drives the gear 205 to rotate. The gear 205 will mesh with the two racks 209 respectively, and drive the two fixed blocks 208 to move closer to each other. The fixed blocks 208 will drive the corresponding trapezoidal sliders 207 to slide in the trapezoidal grooves 206, providing a certain degree of stability for the fixed blocks 208. When the two fixed blocks 208 move closer to each other, they will drive the corresponding connecting rod 212 to move. The connecting rod 212 will drive the fixed rod 211 to move. At this time, the two fixed rods 211 will move closer to each other, and drive the two arc-shaped clamping plates 210 to move closer to the outer wall of cable 4 and clamp and fix it. This achieves the effect of clamping and fixing the cable 4. The two ends of the cable 4 can be effectively clamped and fixed by two driving devices. When the two ends of the cable 4 are clamped and fixed, the second motor 501 is operated, which drives the bidirectional lead screw 5 to rotate. The bidirectional lead screw 5 drives the two sliding blocks 502 to move. Then, the bidirectional lead screw 5 moves the two sliding blocks 502 away from each other. The sliding blocks 502 drive the corresponding U-shaped fixing frame 2 to move. The two U-shaped fixing frames 2 move away from each other and perform tensile testing on the cable 4. Then, the electric push rod 301 is operated, which drives the pressure plate 302 to move up and down. When the pressure plate 302 moves down, it presses down on the outer wall of the cable 4, thereby achieving further repeated bending and compression testing of the cable 4. The cable 4 is tested from multiple angles, which improves the testing efficiency.
