Description

Technical Field

[0001] The present invention relates to the technical field of steel wire rope detection, in particular to an anti-slip type steel wire rope mechanical property detection device. Background Art

[0002] As a material that can withstand large forces, wire rope can be used in many fields, as well as in the construction of related special equipment and construction projects. After the wire rope is processed, in order to ensure that the performance of the wire rope meets the needs of subsequent safe use, the mechanical properties of the wire rope need to be tested. Currently, common testing equipment uses tensioning to test the load that the wire rope can withstand.

[0003] Prior art 1 (publication number CN221260658U, Chinese patent published on July 2, 2024) A wire rope strength detection device with an anti-loosening structure, including a workbench, two movable seats are symmetrically slidably provided on the top of the workbench, and a driving assembly is provided on the workbench for controlling the two movable seats to approach or move away from each other, and a clamping assembly is provided inside the two movable seats; the clamping assembly includes a box body hingedly engaged with the movable seat, and two clamping members are symmetrically slidably provided inside the box body. By setting up a movable seat, a driving assembly, a clamping assembly and a linkage assembly, the purpose of facilitating the placement of the wire rope between two adjacent clamping parts or taking it out from between two adjacent clamping parts is achieved, thereby effectively ensuring the detection efficiency of the equipment. At the same time, when stretching or relaxing the wire rope, the two adjacent clamping parts can maintain a tightly clamped state, simulating the real scene of the wire rope in daily use, and effectively ensuring the detection accuracy of the wire rope; Prior art 2 (publication number CN118111806A, Chinese patent published on May 31, 2024) A wire rope strength detection device is provided, and a fixing part is installed on the mounting plate. When in use, one end of the wire rope is passed through the cavity The wire rope is connected and then fixed to one end of the wire rope by the inner wall of the cavity through the connection between the sleeve and the elastic sheet, and the other end of the wire rope is fixed to the wheel through the fixing part of the pulling member. When the wheel rotates, the wire rope is pulled for testing. When it is pulled to the maximum limit, the rotation of the wheel is limited by the limiting member, so that the wire rope is in the maximum tension state and is maintained, thereby completing the strength test of the wire rope. When in use, the wire rope is fixed by the rotation of the wheel. During the rotation of the wheel, even if the fixing part slips, the wire rope can be fixed by the winding of the wire rope itself, thereby reducing the possibility of separation of the wire rope from the device during the detection process and improving the practicality of the device.

[0004] When current testing equipment is testing wire ropes, the wire rope is tensioned after clamping the ends of the wire rope. When the subsequent tensioning force increases, the clamping point is prone to slippage, affecting the detection accuracy. In addition, the two ends of the wire rope need to be fixed in sequence, which reduces the efficiency of the installation and subsequent removal of the wire rope. At the same time, there is a lack of effective protection during testing, and the accidental disconnection of the wire rope can easily cause damage to the outside world. Summary of the Invention
