Steel belt type buffer variable force energy-absorbing device for preventing cart from running out for inclined shaft

Abstract

The invention discloses a steel belt type buffer variable force energy-absorbing device for preventing a cart from running out for an inclined shaft, belonging to the field of mining equipment. The device comprises a cart baffling fence, a variable force energy-absorbing device and a connecting device. The cart baffling fence comprises a plurality of buffer steel wire ropes, C-shaped casing pipes and suspending chains. The variable force energy-absorbing device comprises a bottom plate combined part, a lateral plate, an upper supporting rod, a mandrel, idler wheels, a screw rod, a nut, a sliding block, a lower supporting rod, a top plate, a top cover and a steel belt. The screw rod is meshed with the nut and connected with the sliding block by bolts and the pressing pins. The nut is arranged between the two lateral mandrels close to the top plate and connected with the lateral plate and the top plate by bolts. The screw rod is meshed with the nut and connected with the sliding block by bolts and pressing pins. The sliding block is semicircular and tightly glued on the steel belt. The steel plate passes through the middle parts of the two idler wheels, and the left end of the steel plate is connected with the steel wire ropes by the connecting device. The steel belt type buffer variable force energy-absorbing device is adjustable in buffering power and reliable in property, and the potential safety hazards caused by cart running out can be further reduced when the steel wire ropes are broken in inclined drifts of coal mines in the conveying process.

Description

Technical field [0001] The invention relates to a variable force energy absorbing device, in particular to a steel belt buffer variable force energy absorbing device for inclined shafts to prevent sports cars, belonging to the field of mining equipment. Background technique [0002] At present, there are mainly two types of anti-sports equipment transported in the inclined lanes of coal mines: one is relatively simple and low-cost equipment, which is welded into a fence gate shape by steel pipes or I-beams, and two sides are installed on one side of the fence gate. A fence gate assembled with vertical shafts and bushings is installed at the lower entrance of the inclined roadway. When a rope-broken sports car occurs during the transportation of the inclined road, the worker pulls the rope to close the fence door and intercept the rope-broken sports car. However, it requires manual activation to produce an action. The interception effect is not good, and it has no cushioning perfo...

Problems solved by technology

Its disadvantages are: the infrared detection equipment is prone to malfunction and cause accidents, and the reliability of the single-chip microcomputer is not high. The buffer device is a linear pressure plate buffer, the buffer force cannot be reliably calibrated, and the buffer performance is poor
