Stone conveying mechanism in tunnel drilling and blasting engineering

Abstract

The invention discloses a stone conveying mechanism in tunnel drilling and blasting engineering. The stone conveying mechanism comprises a transport vehicle which comprises a vehicle hopper and wheels. A telescopic inclined supporting rod is arranged at the rear end of the vehicle hopper and provided with a spiral telescopic driving mechanism, a motor is arranged below the vehicle hopper and drives the wheels, the spiral telescopic driving mechanism and the motor are provided with a wireless receiving device, and the wireless receiving device is provided with a remote controller so as to control the transport vehicle to move and conduct inclined supporting. Nowadays, the tunnel blasting technology is greatly developed, and stones on a blasting surface can fall down in a relatively mild manner after cracks are formed. The stone conveying mechanism can be tightly attached to the blasting surface; after blasting, most of stones falling forwards fall into the vehicle hopper, and through awireless control mode, the transport vehicle can retreat from a tunnel backwards along a track, so that workers are prevented from entering places with a large amount of dust and fume for operation after blasting, and the stones formed by blasting can be quickly and voluntarily loaded.

Description

Background technique [0001] The drill and blast method is a method of excavating rock by drilling, charging, and blasting. It is a common method for tunneling. After drilling and blasting blasting, a large amount of gun smoke will be produced, containing fine particles and harmful gases. Only when the particles and harmful gases are reduced to a reasonable level can construction personnel enter the construction. As the tunnel deepens, ventilation and smoke exhaust will be very difficult. Therefore, the speed of loading and transportation of stones is affected, and the loading and transportation of stones formed by blasting is also very time-consuming and laborious. Contents of the invention [0002] The technical problem to be solved by the present invention is to provide a stone transportation mechanism in tunnel drilling and blasting engineering, which can use blasting to form natural falling rocks to load stones, and can allow the transport vehicle to automatically operat...
