Wire rope overspeed arresting device for overhead passenger rides based on centrifugal transmission mechanism

Abstract

A centrifugal transmission mechanism based wire rope overspeed capturing device of an aerial passenger device mainly comprises a bevel gear wheel, a machine frame, a bevel pinion shaft, a bevel pinion, a supporting spring, a centrifugal sphere, an upper connection rod, a lower connection rod, an upper wedge block, a lower wedge block, an upper spring, a lower spring, a rear connection rod, a guide wheel and the like. When the device works normally, a hook in a lever mechanism hooks a wedge-caulking mechanism, certain gaps are formed between the upper wedge block and a wire rope as well as between the lower wedge block and the wire rope, a centrifugal transmission mechanism is low in rotation speed when a supporting wheel operates at low speed, the hook in the lever mechanism hooks the wedge-caulking mechanism all the time, the positions of the upper wedge block and the lower wedge block are not changed, the upper spring and the lower spring are in a compressed state, and therefore the passenger device pass through the space. When the wire rope cracks or overspeeds, the rotation speed of the supporting wheel is increased, the centrifugal sphere greatly deviates from the bevel pinion shaft, a connection rod in the lever mechanism is driven to rotate around the machine frame greatly, the hook is separated from a shrink-ring on a connection rod shaft sleeve, the upper spring and the lower spring become in a stretching state, the upper wedge block and the lower wedge block are pushed to slide, and the wire rope can be captured in time.

Description

technical field [0001] The invention relates to a steel wire rope overspeed arresting device, in particular to a steel wire rope overspeed arresting device based on a centrifugal transmission mechanism, which is suitable for overspeed protection of steel wire ropes for people transport equipment in coal mines. Background technique [0002] The overhead passenger device has the characteristics of simple structure, low investment, convenient installation, and strong applicability. Therefore, at present, the overhead passenger device has gradually become the first choice for special rapid passenger transport equipment in coal mines. However, in the process of use, the overhead passenger device wire rope Overspeed due to motor failure, and personal injury and death accidents caused by overspeed due to wire rope corrosion, wear, fatigue, shock and vibration, overload, overdue service, uneven load changes, etc., constitute a serious threat to the life safety of coal mine workers. ...

[0002] The overhead passenger device has the characteristics of simple structure, low investment, convenient installation, and strong applicability. Therefore, at present, the overhead passenger device has gradually become the first choice for special rapid passenger transport equipment in coal mines. However, in the process of use, the overhead passenger device wire rope Overspeed due to motor failure, and personal injury and death accidents caused by overspeed due to wire rope corrosion, wear, fatigue, shock and vibration, overload, overdue service, uneven load changes, etc., constitute a serious threat to the life safety of coal mine workers. A great threat, especially the high-inclination aerial passenger device, there is a great potential safety hazard

At present, domestic research on the overspeed arrest of mining overhead passenger equipment is still limited to theoretical research, and no reliable products have been put on the market. The safe operation of overhead passenger equipment has been restricted, making it difficult to guarantee the safe production of coal mining enterprises
