Description

Technical Field

[0001] The utility model relates to insulator tension testing equipment, in particular to an insulator tension testing machine. Background Art

[0002] Composite insulators are essential insulating materials for high-voltage power transmission. They can also avoid arc climbing and improve electricity safety. However, in order to ensure the quality of the insulators during the production process, they need to be tested for tensile strength, bending strength and other stress strengths. In order to ensure the quality of the products, specific testing equipment is required to test the products. However, conventional testing equipment is a vertical testing machine. During the testing process, the insulator products need to be manually lifted onto the fixture and placed vertically before clamping. The safety of the operation cannot be guaranteed during single-person operation, which is time-consuming, labor-intensive and inefficient. In addition, when defective insulator products appear, they are prone to bursting and fragments flying everywhere, and the broken insulators will fall into the equipment at will, which is time-consuming and labor-intensive to clean up. Therefore, it is a technical problem that needs to be solved urgently. Utility Model Content

[0005] The advantage of this solution is that by setting the machine tool into a horizontal structure, the safety of the manual loading and unloading process is effectively reduced. At the same time, there is no need to stand the insulator upright, which reduces the cumbersome operation and labor intensity. The insulator only needs to be clamped horizontally into the fixture, which is simple to operate. In addition, defective products after the explosion can be directly collected through the collection trough without frequent cleaning. Protection is achieved by closing the cover to avoid debris splashing during the tensile test, thereby ensuring detection safety.

Preferably, the through hole is a cone-shaped structure and extends downward, and the upper opening of the collecting bucket is sleeved outside the through hole, so as to prevent the debris from splashing out during the falling process. In addition, during the cleaning process, it is only necessary to take the collecting bucket out from the front of the machine tool, which reduces the cleaning work intensity.

[0008] Furthermore, the collecting tank includes a first collecting tank and a second collecting tank, the fixing fixture is arranged between the first collecting tank and the second collecting tank, and fixtures are arranged on both sides of the fixing fixture, and the fixtures are respectively provided with pressure sensors. Preferably, the fixing fixture is arranged in the middle so that a single insulator can be detected, and both ends of the fixing fixture can also detect the insulators at the same time, thereby improving the detection efficiency.

In order to improve the convenience of using the sleeve, a wrench hole is arranged on the sleeve to facilitate the rotation of the sleeve, ensure the tightening effect of the insulator, and avoid excessive looseness that affects the detection accuracy of its tension.

[0010] Furthermore, the connecting rod is detachably connected to the connecting block on the pressure sensor via a thread, thereby ensuring the connection strength and also enabling the replacement of the fixture to detect insulators of different models, thereby improving its adaptability.

[0011] Furthermore, a driving device is provided on one side of the first collecting trough and the second collecting trough away from the fixing fixture.

[0012] Furthermore, the front end of the machine tool is provided with a door, a PLC control system and a display screen, and the drive devices are all controlled by the PLC control system, which improves the efficiency of product inspection and the convenience of operation, and the inspection data of the product can be intuitively understood and stored.
