Overwinding buffer and tank supporting device for elevating systems of mine vertical shaft and hydraulic system

Abstract

The invention relates to the technical field of mine transportation, in particular to an overwinding buffer and tank supporting device for elevating systems of a mine vertical shaft and a hydraulic system. The overwinding buffer and tank supporting device comprises a transverse beam buffer part and a hydraulic tank supporting part. The transverse beam buffer part comprises hydraulic buffer cylinders fixed to a derrick and a transverse beam located above the hydraulic buffer cylinders. The top of a piston rod of each hydraulic buffer cylinder is hinged to the corresponding end of the lower portion of the transverse beam through three buffer chain links. The invention further provides the hydraulic system matched with the overwinding buffer and tank supporting device. The overwinding buffer and tank supporting device has the advantages that the overwinding collision impact is small, the buffer braking power is stable, the falling distance is short, and tank supporting is reliable and recyclable, and the overwinding buffer and tank supporting device is suitable for overwinding protection for the various elevating systems of the mine vertical shaft.

Description

technical field [0001] The invention relates to an over-rolling buffer support tank device and a hydraulic system of a mine vertical shaft hoisting system, and relates to the technical field of mine transportation, in particular to an over-roll buffering device that adopts crossbeam blocking, a buffer chain plate, and a hydraulic buffer part to perform over-roll buffering, and the support tank hydraulic cylinder lifts the support tank. Zaw's mine shaft hoisting system over-roll buffer support tank device and hydraulic system. Background technique [0002] During the operation of the mine hoist system, if the mine hoist is not stopped in time, the hoist will be over-rolled, so the over-roll buffer device and the tank support device are often used for over-roll buffer and tank support. The overwinding buffer device generally uses a beam to block the lifting container, and the two ends of the beam are connected with a steel wire rope, but the steel wire rope is relatively flexi...

AI Technical Summary

Problems solved by technology

The role of the steel belt is to achieve cushioning and energy absorption, but it cannot achieve reliable tank support. If the hoisting wire rope breaks or the steel belt breaks, the lifting container falls, and the steel belt is difficult to provide sufficient support. Difficulty reliably holding containers within a safe drop distance effectively

At the same time, the steel strip will undergo plastic deformation during use. If an over-rolling accident occurs, the steel strip must be replaced.

[0004] To sum up, the current over-roll buffer support device has the disadvantages of large over-roll collision of the lifting container, some unusable in the case of flexible tanks, the distance of the support device is not variable, or the support tank is unreliable, etc.
