Embodiment 1

[0022] Such as figure 1 As shown, an electronically controlled hoisting wire rope auxiliary tensioning system, the electrically controlled hoisting wire rope auxiliary tensioning system includes a set of auxiliary tensioning device; the auxiliary tensioning device includes a controller, a support frame 1, The electric control clamping device VC1 and the electric control clamping device VC2 for clamping the steel wire rope when retracting and unwinding the rope correspond to each electric control clamping device and are used to detect the position detection sensors S1 and S2 of the electric control clamping device's moving position The supporting frame 1 is provided with a sliding bar with ball bearings 2, and the electronically controlled clamping device VC1 and the electronically controlled clamping device VC2 are arranged on the sliding bar through the ball bearings 2. The electronically controlled clamping device VC1 and the electronically controlled clamping device VC2 are...

Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that in the case where the wire rope is slack in both directions of retracting and unwinding the rope, in order to prevent the slack of the wire rope well, the electronically controlled hoisting wire rope assists tensioning The system includes two sets of auxiliary tensioning devices symmetrically arranged in the direction of wire rope retraction and release. It should be noted that, in other embodiments, the positions of the electronically controlled clamping devices in the two sets of auxiliary tensioning devices can be slightly changed to meet the control program flow.

Abstract

The invention provides an electronically controlled hoisting wire rope auxiliary tensioning system and method. The electrically controlled hoisting wire rope auxiliary tensioning system is composed of one or more sets of auxiliary tensioning devices; the auxiliary tensioning device includes a controller , a support frame, two electronically controlled clamping devices for clamping the steel wire rope when retracting and unwinding the rope, corresponding to each electronically controlled clamping device and a position detection sensor for detecting the moving position of the electronically controlled clamping device; two The electronically controlled clamping device is slidably arranged on the support frame, and a reset mechanism is respectively provided for each electronically controlled clamping device; the controller is electrically connected to the electronically controlled clamping device and the position detection sensor respectively. When taking in or releasing the rope, one electronically controlled clamping device starts and clamps the steel wire rope to move. Disconnect again, another electric control clamping device starts again, so reciprocating.

Description

technical field [0001] The invention belongs to the field of large-scale hoisting equipment in engineering machinery, and in particular relates to an electrically controlled hoisting wire rope auxiliary tensioning system and method. Background technique [0002] In the field of construction machinery, some cranes mainly undertake the construction of large-scale super-high main structures and the hoisting of large-scale equipment. Due to the high lifting height, the hoisting device usually adopts a multi-layer winding method, which often causes chaos in the actual operation process. The phenomenon that the rope or even the wire rope is damaged due to the messy rope. According to investigation and analysis, the phenomenon of rope disorder mainly occurs when the hoisting wire ropes such as fast retracting and releasing ropes with empty hooks, car dismantling, and luffing have no tension relaxation, especially on some cranes that require frequent disassembly and transfer. , suc...
