Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel wire ropes, in particular to a stainless steel wire rope tensile testing device. Background Art

[0002] Wire rope, a flexible, spiral-structured steel product, is widely used in mining machinery, construction, bridges, and other fields. It is widely used in major industries and sectors of the national economy, including coal, metallurgy, transportation, construction, and tourism. Its reliability is crucial to the safe and reliable operation of equipment. It offers many advantages, including high strength, light weight, excellent elasticity, stable and reliable operation, strong ability to withstand dynamic loads and overloads, high-speed operation, and silent winding. Wire rope is a crucial construction tool in coal mine construction sites, and it must be tested using a tensile testing device before being put into use.

[0003] Patent number CN216117111U is a tensile testing device for coal mine wire ropes. By setting a box body, a box body and a box door, the wire rope is provided with a protective function during the wire rope tensile testing, so as to avoid the fragments generated when the wire rope breaks during stretching and causing harm to personnel. The two ends of the wire rope to be tensile tested are respectively placed between the first clamp and the second clamp in the first fixing mechanism and the second fixing mechanism, and the second clamp is driven to move downward by rotating the fixing bolt until the rubber pads on the first clamp and the second clamp are completely and tightly fitted with the wire rope, thereby completing the fixation of the wire rope and improving the firmness of the device in fixing the wire rope. The electric push rod is set to drive the fixed plate to move, and then the connecting rod in the first moving mechanism and the second moving mechanism is driven to rotate and hinge, and then the vertical rod is rotated through the hinge seat, so that the walking wheel is retracted and extended in the groove body, thereby improving the convenience of using the device.

[0004] However, research has found that the existing wire rope tensile testing device still has certain defects:

This clamping is relatively poor in firmness. At the same time, the debris generated when the wire rope is broken needs to be manually collected and cleaned, which is quite troublesome. Therefore, it is necessary to optimize a stainless steel wire rope tensile testing device through technological innovation and design optimization. Utility Model Content
