Abstract

The invention provides an automatic adjustable safety protection vehicle for underground mines and its use method. U-shaped steel frame, direction converter, adjustable length cross bar, U-shaped steel frame fixed rod, hydraulic frame, threaded knob, wire, controller and power unit fixed body. The invention adopts a node-connected structure, does not occupy a large amount of work space, greatly saves the safety protection cost of the mine, and combines a high-power motor and a gear transmission structure to endow the whole device with power that can move freely. At the same time, the safety protection vehicle Equipped with an all-terrain hydraulic frame, the size of the protective vehicle can be adjusted by adjusting the threaded knob on the rod. At the same time, the hydraulic support rod can freely expand and contract, ensuring that the protective device can better adapt to complex road conditions in the mine. working environment.

Description

technical field [0001] The invention belongs to the technical field of safety protection for underground drilling in mines, and in particular relates to an automatic adjustable safety protection vehicle for underground mines and a use method thereof. Background technique [0002] In the process of mining resources, the roof caving accident is one of the high-occurrence safety accidents in the underground, especially after gradually moving towards deep mining, the high ground stress environment makes the top rock more broken. During the underground excavation, drilling and blasting operations The vibration generated can easily lead to the further extension and development of the cracks inside the rock mass, and the layer separation phenomenon occurs in the rock. This construction technology has greatly increased the risk of roof fall accidents underground, which seriously threatens the life, health and safety of underground construction technicians. Therefore, it is necessary...
