Rope adjusting suspension device and method

Abstract

The invention discloses a rope adjusting suspension device and method. The rope adjusting suspension device comprises a rope adjusting suspension framework composed of two suspension main vertical plates, a guide sliding cavity is formed in the rope adjusting suspension framework, an oil cylinder supporting seat is arranged at the top end of the rope adjusting suspension framework, pushing and adjusting oil cylinders are symmetrically arranged in the rope adjusting suspension framework through the oil cylinder supporting seat, and piston rods of the pushing and adjusting oil cylinders are connected with a main clamping wedge component for adjusting the tensile force of the steel wire rope. The rope adjusting suspension device has the beneficial effects that the defects of existing steel wire rope clamping operation are overcome, stability is improved through the design of the double pushing and adjusting oil cylinders, when the main clamping wedge component and an auxiliary clamping wedge component conduct synchronous tensioning force adjustment on the steel wire rope, rope locking and rope releasing stress balance is achieved, the dislocation phenomenon of internal clamping is avoided, the service life of the clamping mechanism and the steel wire rope is prolonged, and the rope can be locked and released conveniently and quickly; and meanwhile, the internal tension of the steel wire rope is automatically adjusted and balanced, the automatic rope adjusting function is achieved, and the working efficiency and the safety performance are improved.

Description

technical field [0001] The invention relates to the technical field of coal mine equipment shaft hoisting and transportation industry, and in particular relates to a rope adjustment suspension device and method. Background technique [0002] In most coal mine hoisting shafts in China, there are two methods of rope adjustment suspension devices commonly used for lifting containers, mainly with spiral rope adjustment device and with hydraulic rope adjustment device. The main disadvantage is that the balance wire rope cannot be automatically adjusted. The internal tension makes the wire rope and the drum groove have different degrees of wear, which increases the amount of maintenance and reduces production efficiency. [0003] Furthermore, when adjusting the tension force of the steel wire rope of the rope-adjusting suspension device, due to the limitation of its structure, although the wedge-shaped connection device is used to clamp and adjust the tension force of the steel wi...

[0002] In most coal mine hoisting shafts in China, there are two methods of rope adjustment suspension devices commonly used for lifting containers, mainly with spiral rope adjustment device and with hydraulic rope adjustment device. The main disadvantage is that the balance wire rope cannot be automatically adjusted. The internal tension of the steel wire rope and the drum rope groove have different degrees of wear, increasing the amount of maintenance and reducing production efficiency

[0004] When adjusting the rope in the shaft, sometimes the phenomenon of "squatting in the pot" often occurs, which makes the two oblique wedges inside the existing hydraulic rope adjustment device out of sync, resulting in dislocation clamping and damage to the clamping oblique wedge, resulting in failure to clamp Wire rope, causing safety hazards or accidents, and readjustment is time-consuming and laborious

In addition, every time the rope is adjusted, the locking rope clamp must be repeatedly disassembled, which is slow and inefficient, and has a great impact on safety performance.
