Technical Field

The utility model relates to a tunnelling machine especially relates to a tunnelling equipment operation panel shelter from protection mechanism.

Background

In the process of roadway driving construction in China, most rock roadways adopt a blasting excavation process, and the broken stones flying out during blasting easily break unprotected parts on equipment, particularly important parts such as an operating handle and instruments on an operating platform. In order to avoid blasting flying stones to break equipment in mines, construction equipment is required to be withdrawn from a blasting surface for a distance of dozens of meters before blasting, and because a roadway is narrow and light rays are not good, and the traveling speed of the equipment is not high, the time required for the equipment to withdraw from the working surface and enter the working surface again after blasting is long in order to avoid blasting, so that the real working time is short, and the tunneling efficiency of the roadway is severely limited; sometimes, because of the non-standard of the drilled blast hole, the rock and explosive, etc., the phenomenon that the blasting ballast flies out farther and smashes the handle or the instrument on the operation table is also caused.

Therefore, it is an urgent need to solve the problem of providing a shielding protection mechanism for an operation table of drilling, loading and anchoring roadway excavation equipment.
