Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] A chute safety protection device includes an upper cover 4 , a lower cover 5 , and an airbag 1 . The airbag 1 is arranged below the upper cover 4 and surrounds the outer side of the lower cover 5 . The outer ring of the airbag 1 is provided with a waterproof cushion 6, and the waterproof cushion must be tightly wrapped or pasted on the outer ring of the inflatable airbag. The cross section of the air bag is circular or oval. The air bag is corrugated, and the number of curved bags is 13. The size of the air bag is slightly smaller than the radius of the lower cover plate 5, because the air bag has elasticity, so the air bag can be tightly fixed on the lower cover plate.

[0024] The edge of the upper cover plate 4 is provided with an air intake hole 2, and the air intake nozzle of the airbag 1 communicates with the air intake hole 2, so as to facilit...

Abstract

The invention discloses a chute safeguard device and aims to solve the problems that over-simplicity of a traditional treatment method of a discarded chute causes great potential hazards to production safety and a traditional closure wall for closing access roads, having no waterproof function, contaminates the chute. The chute safeguard device comprises an upper cover plate, a lower cover plate and a balloon; the balloon is disposed below the upper cover plate and surrounds the circumference of the lower cover plate. The balloon is disposed below the upper cover plate and surrounds the outer side of the lower cover plate. The underground mine operational safety condition is greatly improved, and the chute safeguard device has the advantages that contact tightness is good, water resistance is good, universality is good, mounting is time saving and labor saving, and the device is reusable.

Description

technical field [0001] The invention belongs to the field of mining engineering, and in particular relates to a shaft safety protection device. Background technique [0002] The chute is a facility for storing and transporting minerals in an underground mine, and the minerals are transported through the chute. When a certain middle section of minerals is mined, the chute is abandoned thereupon. Over the years, mines have only dealt with the abandoned chute by simply sealing the connection between the transport roadway and the chute with waste rocks or wood, so as to prevent accidents caused by mine workers entering the chute by mistake. [0003] The traditional way to deal with abandoned chutes is too simple. Due to the incomplete closure of the connecting road or the collapse of the closed wall due to the vibration of underground blasting, underground workers accidentally entered the chute and caused accidents. Great hidden danger. [0004] On the other hand, the chute h...
