Problems solved by technology

[0006] Therefore, testing the overall performance of the existing seat belts to ensure the quality of seat belt products is an important link in the production of seat belts; in the existing testing equipment, usually only the performance test of a single type of seat belt can be realized, or only the static tension can be realized The test of a single performance parameter such as numerical value is inconvenient to test. To test a variety of different seat belts, it is necessary to set up a variety of different test equipment, which is costly and inconvenient to operate.

Embodiment 1

[0070] figure 1 It is a schematic diagram of the multi-station safety belt overall performance testing device disclosed in Example 1.

[0071] In Embodiment 1, the multi-station safety belt overall performance testing device includes a device chassis 1, which is a square structure, and the square structure device chassis 1 is the load-bearing structure of the test device, and is also a setting structure for some components. The motor is arranged inside the device chassis 1 with a square structure; the bottom of the device chassis 1 is provided with a first support foot 12, which is used to place the device chassis 1 stably and smoothly;

[0072] The device column 2 is set and fixed on the device chassis 1. The two device columns 2 are arranged parallel to each other and spaced apart, perpendicular to the device chassis 1. The two device columns 2 form a pillar for installing the stretching rod 3. The device column 2 is equipped with precision Ball screw pair;

Abstract

A multi-station safety belt overall performance testing device comprises a device chassis; two device stand columns which are fixedly connected to the device chassis in parallel at intervals in a perpendicular mode; a stretching rod which has two ends movably connected with the two device stand columns respectively and is driven by external force to move up and down along the two device stand columns; an alternating current servo motor which is arranged in the device chassis and is used for driving the stretching rod to move; a first pull ring which is arranged on and connected with the stretching rod and is used for hanging a safety belt to be tested; a tension sensor which is arranged on the stretching rod and is used for testing the tension borne by the safety belt; and a multi-stationrotary test platform, wherein the multi-station rotary test platform is matched with the two device stand columns, and a platform rotating disc rotates to rotate a station to the position below the stretching rod, so that the overall performance of the safety belt is tested through a simulated dummy arranged on the station.

Description

technical field [0001] The application belongs to the technical field of safety equipment, and in particular relates to the testing technology of individual safety equipment, in particular to a device for testing the overall performance of a multi-station safety belt. Background technique [0002] The safety belt is a protective product that prevents the operator from falling or hangs the operator safely in the air after the fall occurs. Usually safety belts include pole work safety belts, area restriction safety belts and fall suspension safety belts. [0003] The pole work safety belt binds the operator near the component through a rope or belt around the fixed component, so that the operator's hands can perform other operations. The overall static tension should not be less than 4.5KN, and there should be no webbing Tear, open wires, broken metal parts, open connectors, broken ropes, plastic deformation of metal parts, slipping of the simulated human, etc. [0004] Area...
