Tunnel hanging bracket for coal mine overhead man-riding device

Abstract

The invention discloses a tunnel hanging bracket for a coal mine overhead man-riding device. The tunnel hanging bracket comprises a cross beam, a first support is arranged on one side of the bottom ofthe cross beam, and a second support is arranged on the side, away from the first support, of the bottom of the cross beam; a first damper is installed between the first arc-shaped clamping block andthe third arc-shaped clamping block through bolts, and a second damper is installed between the second arc-shaped clamping block and the fourth arc-shaped clamping block through bolts; a third damperis installed between the fifth arc-shaped clamping block and the sixth arc-shaped clamping block through a bolt, and a fourth damper is installed between the seventh arc-shaped clamping block and theeighth arc-shaped clamping block through a bolt; and lifting clamping structures are installed at the two ends of the top of the cross beam. Under the supporting effect of the dampers, the hanging bracket can be more stable and has better anti-seismic stability; and meanwhile, under the cross supporting effect of tensile inclined rods, the overall stability of the hanging bracket is better, the hanging bracket is not prone to deformation when a tunnel is subjected to seismic vibration, so that the safety of the overhead man-riding device in the tunnel is improved.

Description

technical field [0001] The invention relates to the technical field of mine cableways, in particular to a tunnel hanger for a coal mine overhead passenger device. Background technique [0002] The mine cableway is mainly composed of driving device, tail wheel and tensioning device, passenger part, steel wire rope, supporting (pressing) wheel part, electric control part and comprehensive protection device. The protection devices should be equipped with: head and tail offside protection, heavy hammer lower limit protection device, steel wire rope life limit protection, emergency stop protection along the entire roadway, protection device for falling rope on uphill and down slopes, voice prompts when people get on and off the station, and rope broken protection , hanging chair anti-overswing reducer temperature oil level and other safety devices. [0003] Mining cableways are installed in underground coal mines. Due to the low stability of some hangers during earthquakes, when...

Problems solved by technology

[0003] Mining cableways are installed in underground coal mines. Due to the low stability of some hangers during earthquakes, when facing shock waves, the structure of the hangers is unstable and prone to deformation. The safety factor is low, and the traditional hangers It is difficult to effectively adjust the height of itself, and it is inconvenient to use. At the same time, some hangers are bulky and inconvenient for long-distance transportation
