Description

Technical Field

[0001] The utility model relates to the technical field of wire rope locking, in particular to a wire rope locking device with adjustable pre-tightening force. Background Art

[0002] A wire rope is a helical bundle of steel wires twisted together according to specific rules, each with its own specific mechanical properties and geometric dimensions. During use, after lifting a heavy object to a certain height, the wire rope must be locked to ensure it remains at that height. This is typically achieved using a clamping-type locking device.

[0003] When using a clamping locking device, the wire rope passes through two clamping plates. The clamping plates are adjusted with bolts to lock the wire rope. The bolts can also be used to adjust the preload force. However, in the clamping locking device, the clamping force of the wire rope is unevenly distributed due to the clamping plates being used to fix the wire rope, which affects the locking effect. In addition, the clamping plates are adjusted with bolts, which has poor stability after adjustment and is prone to loosening, thus affecting the locking effect. The use effect is generally poor.
