Cage supporting and stabilizing device based on dead points of two four-bar mechanisms

Abstract

The invention discloses a cage supporting and stabilizing device based on dead points of two four-bar mechanisms. The cage supporting and stabilizing device based on the dead points of the two four-bar mechanisms comprises a machine frame (1), a supporting four-bar mechanism (14), a stabilizing four-bar mechanism (15) and a rocker arm rear platform (13). According to the cage supporting and stabilizing device based on the dead points of the two four-bar mechanisms, by means of the dead point characteristic of the four-bar mechanisms, a cage can be supported smoothly and safely and stabilized firmly, the situation that the cage moves up and down due to the elasticity of suspension steel wire ropes is effectively avoided, the cage can be loaded and unloaded more stably and more reliably, the safety performance of equipment is effectively improved, the structure is simple and reliable, operation is flexible, a large power source is omitted, and the effect is obvious.

Description

technical field [0001] The invention relates to a cage receiving and stabilizing device based on the dead point of a double four-bar linkage mechanism, in particular to a cage lifting device used in mine vertical shafts to prevent up and down movement due to the elasticity of steel wire ropes during loading and unloading, and to ensure the loading and unloading process of the cage stable and safe. Background technique [0002] Mine vertical hoisting is an indispensable way of transporting personnel, equipment and materials in mineral production activities, and plays a decisive role in the coal mining process. In the work and production of mine vertical hoisting, the hoisting system adopts friction hoisting more widely than winding hoisting. In the deep vertical mine friction hoisting system, due to the large depth and heavy load of the hoisting system, the elastic elongation of the hoisting wire rope is relatively large, and the cage rebounds seriously due to the elastic fo...

Problems solved by technology

The patent application number is 200810020506.3, which discloses a tank stabilization mechanism and tank stabilization device for vertical shaft cage lifting. It has the functions of tank holding and tank stabilization, and can accurately and safely realize docking when the load difference between the in and out of the cage is large. , but its price is too high, the operation is cumbersome, and it cannot be adjusted to compensate for the change in the length of the hoisting wire rope during loading and unloading; the patent application number is 200810150559.7, which discloses a vertical mine hoisting container lock tank stabilization tank and over-winding and over-discharging braking device. During use, it needs to work in coordination with the cradle, and during the working process, the brake action can be performed when the cage is over-rolled or over-discharged due to equipment failure or improper operation. Since the brake plates are installed on both sides of the lifting container, the invention In practical application, it may affect the layout of the wellbore section; the patent application number is 201010170178.2, which discloses a two-way sensory compensation tank lock device for lifting the container, which has the functions of automatic compensation for the elastic-plastic elongation of the steel wire rope, accurate positioning of the cage, and adjustable It has the advantages of stopping the tank error, reducing the impact and deformation of the cage, and convenient unlocking, etc., but its structure is relatively complicated and the cost is high

[0004] These tank-holding and stabilizing devices are relatively complex and more or less dependent on the load to a certain extent, requiring the help of a large power source to complete the required functions, which greatly increases the cost of the equipment
