Hydraulic pressure sideward releasing type pedestrian hole device for sharp inclined coal seam

Abstract

The invention discloses a hydraulic pressure sideward releasing type pedestrian hole device for a sharp inclined coal seam. The hydraulic pressure sideward releasing type pedestrian hole device for the sharp inclined coal seam comprises thick wall flaring barrels, connecting hinges, hydraulic supporting columns, a hanging ladder, a cover top and a door plate, wherein each thick wall flaring barrel comprises a thick wall flaring barrel neck and a thick wall flaring barrel abdomen, the diameter of each thick wall flaring barrel neck is smaller than the diameter of the corresponding thick wall flaring barrel abdomen, the thick wall flaring barrels are connected with the hydraulic supporting columns in sequence from bottom to top through the connecting hinges, the thick wall flaring barrels are arranged in a whole pedestrian hole, and the thick wall flaring barrel neck of each thick wall flaring barrel and the thick wall flaring barrel abdomen of the corresponding upper thick wall flaring barrel partially overlap; the cover top is connected to the upper port of the uppermost thick wall flaring barrel, the cover top is located in a gate road on a mining working face when used, the door plate is installed on one side of the cover top and used for allowing personnel to enter or come out of the hydraulic pressure sideward releasing type pedestrian hole device for the sharp inclined coal seam, and the hanging ladder is hung in the thick wall flaring barrels which are connected in sequence. According to the hydraulic pressure sideward releasing type pedestrian hole device for the sharp inclined coal seam, accidents such as waste rock spreading and coal falling of the pedestrian hole can be effectively prevented, and safety of pedestrians is fully guaranteed.

Description

technical field [0001] The invention relates to a coal seam pedestrian eye device, in particular to a steeply inclined coal seam pedestrian eye device. Background technique [0002] In my country's energy structure, coal accounts for 70% of my country's primary energy consumption, and is the foundation of my country's economic development and social stability. Among them, coal reserves with a coal seam dip angle greater than 30° account for 15% of the total reserves and about 10% of my country's total coal output. However, due to the poor mining conditions of the steeply inclined coal seam, the unstable occurrence of the roof, floor and coal seam, the phenomenon of toppling of the support and gangue on the working face often occurs, so it is necessary to excavate special pedestrian eyes for the workers in the working face, so that the working face can move smoothly up and down. The trough connects walking and transports auxiliary materials. [0003] However, since the pede...

Problems solved by technology

[0005] In order to solve the problems in the prior art that the eyes of pedestrians in steeply inclined coal seams are prone to gangue and coal fall, the safety of pedestrians cannot be guaranteed, the eyes of pedestrians cannot be strongly supported, and the deformation is serious. device
