Description

Technical Field

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

[0002] Currently, cables are prone to aging during prolonged use, which can lead to a decline in cable performance and even damage equipment. Existing cable aging detection methods mainly focus on visual inspection of the cable's exterior or the use of traditional electrical testing methods. However, these methods cannot provide accurate monitoring of the cable's internal condition and cannot perform real-time detection during operation.

[0003] However, existing testing devices have certain drawbacks. They cannot change the influence of external ambient temperature during testing, and they cannot adjust the influence of the tensile force that the cable can withstand, which has a certain impact. Therefore, there is an urgent need for a cable aging testing device to solve the above problems. Utility Model Content

[0004] To solve the above problems, this utility model provides a cable aging test device, which is achieved through the following technical solution.

Inside the test chamber is a movable cable clamping frame with positioning holes on both sides. A compression plate on the cable clamping frame is movably engaged with the frame. A fastening bolt is passed through the cable clamping frame, with one end rotating on the compression plate. A hydraulic cylinder is fixedly connected to the cable clamping frame, and a pressure sensor is fixedly connected to the telescopic end of the hydraulic cylinder. A compression roller is fixedly connected to the pressure sensor. The device also includes:

[0006] A power mechanism for driving the cable clamp frame to move up and down inside;

[0007] A temperature control mechanism is used to regulate the temperature inside the test chamber.

[0008] Furthermore, the power mechanism includes a transmission box and a lead screw. The lead screw is rotatably connected inside the test box via a fixed plate. A second helical gear is fixedly connected to one end of the lead screw that extends into the transmission box.

A worm gear is fixedly connected to the middle of the transmission rod, and a servo motor is fixedly connected to the bottom of the transmission box. The worm gear fixed to the output shaft of the servo motor meshes with the worm gear.

[0010] Furthermore, the lead screw passes through and is threaded into the cable clamp, and the second helical gear meshes with the first helical gear.

[0011] Furthermore, the temperature control mechanism includes a temperature controller, which is fixedly connected to the rear side of the test chamber. The temperature controller is connected to the test chamber and interconnected with it through a transmission pipe. A temperature sensor is fixedly connected inside the test chamber.

[0012] Furthermore, the top of the test chamber is covered with a lid, and the test chamber and the lid are hinged together.

[0013] The beneficial effects of this utility model are that, during the operation of this device, the cable to be tested is first inserted into the positioning hole on the cable clamp frame. By rotating the fastening bolt, the extrusion plate is moved. The extrusion plate, together with the cable clamp frame, clamps and fixes the cable. Then, the temperature inside the test chamber is adjusted by the temperature control mechanism. Next, the extrusion roller is pushed up by the hydraulic cylinder. The rising extrusion roller can extrude the fixed cable to be tested. The pressure sensor can monitor the extrusion force, thereby enabling the testing of the aging degree of the cable to be tested based on the tensile force and the influence of external temperature.
