Description

Technical Field

[0001] The invention belongs to the technical field of tension testing devices, and in particular relates to a tension testing device for a safety belt of a person working at height. Background Art

[0002] A high-altitude safety harness is a piece of protective equipment designed specifically for aerial work, securing workers in place to prevent accidental falls. Impact testing simulates the unexpected situations encountered during actual operations, verifying the belt's performance under impact and ensuring it performs effectively at critical moments to protect workers.

[0003] In the existing technology, safety belts are mostly tested by vertical tensile testing. However, the safety belts of height workers are composed of multiple cross-belts. The vertical tensile test cannot simulate the body shape of height workers, resulting in inaccurate test data. In addition, in the existing technology, when the tensile test exceeds the maximum load-bearing capacity, the safety belt will break. The broken collision of the safety belt may cause unpredictable injuries to the experimenters on site. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a safety belt tension testing device for high-altitude workers.

[0007] In the above technical solution, further, the stretching clamp mechanism includes a fixed disc fixedly installed on the lower surface of the lifting plate, a clamping platform is provided at the lower end of the fixed disc, two limiting clamping rollers are provided on the inner wall of the clamping platform, a movable roller is provided at the lower end of the limiting clamping roller, and through grooves are provided on both sides of the inner wall of the clamping platform.

[0008] In the above technical solution, further, a limiting round rod is provided in the left through slot, and a lifting screw penetrating the clamping platform is provided in the right through slot, and the lifting screw penetrating the movable roller.

[0009] In the above technical solution, further, the hanger moving mechanism includes four fixed cylinders in a square shape fixedly mounted on the upper surface of the base, and fixed screws are installed through the four corners of the upper surface of the fixed cylinders, and the fixed screws are rotatably matched with the fixed cylinders.

[0010] In the above technical solution, further, two slide rails are provided on the upper surface of the base between the fixed cylinders, a slider is provided on the lower surface of the fixed bottom plate, and a baffle is provided at the rear end of the slide rails.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The use of a protective net can effectively prevent the breakage during the test and the splashing of debris. By controlling the moving roller to clamp the safety belt, it can prevent the situation of unlocking during the test.
