Electric power fitting abrasion test device

Abstract

The invention discloses an electric power fitting abrasion test device. The electric power fitting abrasion test device comprises a rack, a positioning box, a limiting plate, a hydraulic machine, a movable plate, a mounting plate, fixed hinges, a clamp, fixed plates, mounting holes, fixed holes, clamping grooves, a test box, a supporting rod, pull rods, positioning rods, rotating shafts, a motor,a bearing and a rotating rod; the positioning box is welded at the top of the rack; the inner wall of the positioning box is fixedly welded with the outer wall of the limiting plate; the hydraulic machine is fixedly mounted at the top of the positioning box; and the bottom of the hydraulic machine is welded and fixed to the top of the mounting plate. According to the device, the fixed holes are formed in the clamp, so that a U-shaped ring are mounted and fixed; the mounting holes are formed in the fixed plates, so that a suspension clamp is mounted and fixed; the clamping grooves are formed inthe clamp, so that the bottom of the clamp is clamped with a test part, and the abrasion test of electric power fittings is achieved; and the clamp part is suitable for various different electric power fittings, so that the test requirements are met, and the replacement frequency of the clamp is reduced.

Description

technical field [0001] The invention belongs to the technical field of test devices, in particular to a wear test device for electric fittings. Background technique [0002] Power fittings such as U-shaped rings and suspension clamps commonly used in the construction of transmission lines need to bear large vertical loads and large swings during their use. In such cases, many power fittings use Less than a year later, serious wear and tear occurred, thereby posing potential safety hazards and requiring regular replacement. While consuming manpower, financial and material resources, it also affected normal production and life. Therefore, users must clearly grasp the wear resistance of the above-mentioned power fittings before use, and conduct wear tests on power fittings from different companies and even different batches of power fittings, so as to select power fittings with better wear resistance. The existing test fixtures are not suitable for various electric fittings, c...
