Hoisting container rope-loosening and rope-tightening suspension device and rope-loosening rope-tightening method thereof

Abstract

The invention relates to a hoisting container rope-loosening and rope-tightening suspension device and a rope-loosening and rope-tightening method thereof. The suspension device comprises a rope ring and a hydraulic pressurization system capable of loosening and tightening the rope ring, wherein both sides of a clamp board of the rope ring are symmetrically provided with wedge-shaped block loosening and tightening devices; the hydraulic pressurization system is provided with a manual pressurization cylinder, a hydraulic pump and a plurality of pressurization cylinders connected in series, oiloutlets of the pressurization cylinders and oil inlets A of the wedge-shaped block loosening and tightening devices are connected with a loosened rope, and oil inlets B of the pressurization cylinders are connected with a tightened rope. The device has the advantages of rapid connection and rapid disconnection of a hoisting rope end, simple structure and reliable performance, is easy for machining and convenient for installation and maintenance and is applicable to suspension connection of a large hoisting container and a hoisting rope of a mine well hoisting system.

Description

technical field [0001] The invention relates to a hoisting container slack rope tight rope suspension device and a slack rope tight rope method thereof, and is especially suitable for the suspension connection of a hoisting container with a large depth in a mine and a hoisting wire rope. Background technique [0002] The production of large-scale coal enterprises (Zhangji Mine in Huainan, Zhaozhuang Mine in Jincheng, Hujiahe Mine of Shaanxi Binchang Company, Shaqu Mine in Shanxi, Huangyuchuan Mine, etc.), super-large equipment (such as heavy-duty flatbed trucks weighing up to 39 tons, skips up to 40 tons, etc.) are used in mines, and the reliability of the connection and the convenience of disassembly between the hoisting rope and the hoisting container are gradually being paid attention to. At present, although the suspension device connected between the hoisting rope and the hoisting container adopts a wedge-shaped rope loop to be connected reliably, it has the following d...

AI Technical Summary

Problems solved by technology

At present, although the suspension device connected between the hoisting rope and the hoisting container adopts a wedge-shaped rope loop to be connected reliably, it has the following disadvantages: (1) When the lifting rope is replaced or the position of the rope end is changed, the self-locking wedge-shaped rope loop is applied to The high extrusion force of the hoisting rope makes disassembly difficult; (2) During the process of connecting the hoisting rope, the rope ring cannot be pre-tightened, so it needs to drive the winch several times for pre-tightening and correction, which affects the production efficiency of coal enterprises. had a greater impact
