A kind of tunnel digging equipment with protective structure

Abstract

The invention discloses a tunnel excavation equipment with a protective structure, comprising a buffer assembly, a chassis, a fixed frame, a dustproof net, a driving box, a supporting leg, a U-shaped plate, a pull block, a fixed rod, a movable plate and a connecting rod , slider, first spring, first fixed column, fixed block, connecting column, sliding rod, fixed seat, block seat, rotating plate, block rod, hydraulic telescopic rod, second fixed column, support rod, sliding seat and block The top of the center of one side of the chassis is welded to one side of the fixing rod, and the two sides of the bottom end of the fixing rod are welded to the two sides of the top of the fixing frame respectively, and one end of the side center of the fixing rod is respectively connected to the fixing block Welding on one side of the invention, the invention has a simple structure and is easy to use. The installed dustproof net reduces the damage rate of the chassis, which is beneficial to the normal operation of the invention. At the same time, the additional buffer components prevent the falling rocks from being directly connected to the driving box. The body collides, causing damage to the driving box and endangering the life of the driver.

Description

technical field [0001] The invention relates to the technical field of excavating equipment, in particular to a tunnel excavating equipment with a protective structure. Background technique [0002] A tunnel refers to a channel dug out of an existing building or earth-stone structure. It is an engineering building buried in the ground and is a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mine tunnels. In the process of tunnel excavation, tunnel excavation equipment is indispensable, including excavators. When excavators excavate tunnels, excavators do not It is beneficial to protect the rockfall falling from the top of the tunnel, which will cause damage to the driving box and is not conducive to protecting the driver. At the same time, when excavating inside the tunnel, due to the small space inside the tunnel and the low ventilation efficiency, the dust inside the tunnel will fly, causing the...
