Description

Technical Field

[0001] The utility model relates to the technical field of steel strand detection, in particular to a stretching device used for steel strand detection. Background Art

[0002] Steel strands are the main load-bearing members of load-bearing components such as building structures and power facilities. In order to ensure that their strength reaches the set value, they need to be strength tested before leaving the factory and before use. Since steel strands are multi-strand structures, traditional tensile clamps are not suitable as clamps for steel strands. According to publication number CN220625992U, a tensile testing device for steel strands is disclosed, which includes a testing table, on which a bracket and a hydraulic cylinder are installed, one clamp is installed on the side of the bracket facing the hydraulic cylinder, and the other clamp is installed on the piston rod of the hydraulic cylinder through a tension sensor. Each clamp includes a conical locking hole and a clamp installed in the locking hole, and the small end of the locking hole faces the other clamp; the wire clamping hole of the clamp has an inner surface that simulates the twisting of the steel strand, and the first clamp and the second clamp of the clamp are cut from the same section of steel pipe through a virtual plane passing through the center line of the steel pipe; the clamp has an outer circumference with the same shape as the inner circumference of the locking hole, and the large end of the clamp extends outward from the large end of the locking hole. The present application utilizes the inner surface of the wire clamping hole to simulate the twisted steel strand, and stably connects the steel strand to the clamp, so that the steel strand is evenly squeezed, can maintain its shape, and will not slip, thereby ensuring the accuracy of the test results. However, it is relatively laborious to manually tighten the steel strand during operation, and it may not be possible to tighten it. When the clamp is loose, the final tensile data will be affected. In addition, when one end of the steel strand is fixed and stretched, the other end will affect its final data, and when the position is changed, it needs to be re-fixed, which is time-consuming and affects efficiency. Therefore, it is urgent to design a stretching device for steel strand detection to solve the above problems. Utility Model Content
