Description

Technical Field

[0001] This utility model relates to the field of charging pile cable testing technology, specifically a charging pile cable testing device. Background Technology

[0002] Charging pile cables are key components connecting charging piles and electric vehicles, responsible for power transmission; their selection and maintenance are crucial. Tensile testing of charging pile cables is an important step in ensuring cable quality and safety. The purpose of this test is to verify the cable's mechanical strength and structural stability, ensuring that the cable can withstand mechanical and thermal stresses without failure under normal use and emergency conditions.

[0003] The existing Chinese patent announcement number CN218974020U, entitled "A Testing Device for the Tensile Performance of Charging Pile Cables," explicitly states in its abstract that "this application uses a bidirectional threaded rod. When materials are placed, the motor is turned on to drive the bidirectional threaded rod to rotate. When the bidirectional threaded rod rotates, it drives the second moving blocks on both sides to move to a limit position. Then, the second moving blocks drive the first clamping plate to clamp and fix the cable. If the cable is small, the second clamping plate and the rubber pad are clamped by rotating the bolts to prevent the cable from falling off during the test and to improve the efficiency of the test."

[0004] However, this technology only measures tensile performance through simple tensile tests, lacking the ability to test the tensile performance of cables under high-temperature environments, resulting in incomplete test results. Furthermore, during tensile testing, the cable may suddenly break due to excessive tension, and the device lacks sufficient protective measures, causing broken cables or components to fly out and injure operators. Utility Model Content

[0005] The purpose of this utility model is to provide a charging pile cable testing device to solve the problems mentioned in the background art, such as the lack of testing capability for the tensile performance of cables under high temperature environment and the lack of sufficient protective measures of the device, which leads to broken cables or components flying out.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A charging pile cable testing device includes a mounting base and a protective shell, wherein a heating component is provided on the mounting base;

[0008] The heating assembly includes a rotating groove, inside which a rotating component is rotatably disposed, and a heating element is disposed at the bottom inner side of the rotating component.

[0009] In a preferred embodiment of this utility model, a tension sensor is provided on the front side above the mounting base, and a sliding groove is provided on one side of the rotating groove.

[0010] In a preferred embodiment of this utility model, a first fixing groove is provided at the tension detection point of the tension sensor, and a second fixing groove is slidably provided above the sliding groove.

[0011] In a preferred embodiment of this utility model, a pressure plate is provided inside the first fixing groove and the second fixing groove, and an electric push rod is provided at the top of the first fixing groove and the second fixing groove, with the telescopic end of the electric push rod connected to the pressure plate.

[0012] In a preferred embodiment of the present invention, a threaded opening is provided at the bottom of the second fixing groove, and a threaded rod is rotatably provided inside the sliding groove, the threaded rod being threadedly connected to the threaded opening.

[0013] In a preferred embodiment of this utility model, slide rails are provided on both sides of the outer side of the slide groove, and the protective shell is slidably connected to the slide rails.

[0014] In a preferred embodiment of this utility model, a ball bearing is provided on the side of the rotating groove connected to the rotating component, and a first gear is provided on the outer front side of the rotating component.

[0015] In a preferred embodiment of the present invention, a motor is provided at the top of the rotating groove, and a second gear is provided on the motor drive shaft, the second gear meshing with the first gear.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0017] Beneficial effects: By pushing the pressure plate with electric push rods on both sides, the two ends of the cable can be fixed in the first and second fixing slots respectively. During tensile testing, the protective shell is slid above the groove. The protective shell effectively prevents the cable from breaking and flying out, thus avoiding injury to the operator. The cable is preheated by the heating element. The motor drives the second gear to rotate. Through gear transmission, the first gear and rotating parts are rotated. The heating element heats the cable 360°, thus simulating the tensile performance testing capability under high temperature environment, making the test results more comprehensive.

Detailed Implementation

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Please refer to Figures 1-5 This utility model discloses a charging pile cable testing device, including a mounting base 1 and a protective shell 3. The mounting base 1 is the bottom structure of the device, used to support and install the overall structure. The protective shell 3 is a protective structure, which effectively prevents the cable from breaking and flying out during tensile testing, thus avoiding injury to the operator.

[0028] A tension sensor 11 is provided on the front side above the mounting base 1. A sliding groove 12 is provided on one side of the rotating groove 31. A first fixing groove 13 is provided at the tension detection point of the tension sensor 11. A second fixing groove 14 is slidably provided above the sliding groove 12. The bottom structure of the second fixing groove 14 is stuck in the sliding groove 12 and slides. A pressure plate 21 is provided inside the first fixing groove 13 and the second fixing groove 14. An electric push rod 2 is provided at the top of the first fixing groove 13 and the second fixing groove 14. The telescopic end of the electric push rod 2 is connected to the pressure plate 21. By placing both sides of the cable in the first fixing groove 13 and the second fixing groove 14 respectively, the pressure plate 21 is pushed by the electric push rods 2 on both sides. The pressure plate 21 squeezes the cable, and the two ends of the cable can be fixed in the first fixing groove 13 and the second fixing groove 14 respectively.

[0029] The bottom of the second fixing groove 14 is provided with a screw hole 22, and a threaded rod 23 is rotatably provided inside the slide groove 12. The threaded rod 23 is threadedly connected to the screw hole 22. That is, by rotating the threaded rod 23 on the outside, the second fixing groove 14 is moved backward. By tightening the cable and continuously pulling it, the tensile performance of the cable can be detected by the tensile sensor 11. Slide rails 24 are provided on both sides of the outside of the slide groove 12, and the protective shell 3 is slidably connected to the slide rails 24. That is, the protective shell 3 slides, which facilitates the installation and disassembly of the cable in the second fixing groove 14. When performing tensile testing, the protective shell 3 is slid above the slide groove 12.

[0030] The mounting base 1 is equipped with a heating component for heating the cable to simulate the tensile strength test under high temperature conditions. The heating component includes a rotating groove 31, inside which a rotating element 32 is rotatably mounted. During installation, the cable passes through the rotating element 32. A heating element 33, which is a heating tube, is located at the bottom inner side of the rotating element 32, forming a complete heating structure including a heating control element. The cable is heated via the heating element 33. A ball bearing 34 is rolled along the connection between the rotating groove 31 and the rotating element 32. The rotating part 32 is not in direct contact with the rotating part 31. The rotating part 32 is supported by the ball bearing 34 and rotates smoothly through the ball bearing 34. A first gear 4 is provided on the outer front of the rotating part 32. A motor 41 is provided on the top of the rotating groove 31. A second gear 42 is provided on the drive shaft of the motor 41. The second gear 42 meshes with the first gear 4. The motor 41 drives the second gear 42 to rotate. Through gear transmission, the first gear 4 and the rotating part 32 rotate, so that the cable can be heated 360° through the heating element 33.

[0031] The working principle of this utility model is as follows: By placing both sides of the cable in the first fixing groove 13 and the second fixing groove 14 respectively, the electric push rods 2 on both sides push the pressure plate 21, and the pressure plate 21 squeezes the cable, thereby fixing both ends of the cable in the first fixing groove 13 and the second fixing groove 14 respectively. By rotating the threaded rod 23 on the outside, the second fixing groove 14 is moved backward. By tightening the cable and continuously pulling it, the tensile performance of the cable can be detected by the tension sensor 11. During the tensile test, the protective shell 3 is slid above the slide groove 12. The protective shell 3 effectively prevents the cable from breaking and flying out, which could cause injury to the operator. The heating element 33 preheats the cable, and the motor 41 drives the second gear 42 to rotate. Through gear transmission, the first gear 4 and the rotating part 32 rotate, so that the heating element 33 heats the cable 360°, thereby simulating the tensile performance test capability under high temperature environment, making the test results more comprehensive.
