A hinged double propulsion beam propulsion mechanism

Abstract

The invention belongs to the technical field of tunnel drilling facing the empty surface, and relates to a hinged double-propelling beam propelling mechanism. A hinged double propulsion beam propulsion mechanism involved has a propulsion beam support; the propulsion beam support has a bottom plate and an isosceles triangular plate connected to both ends of the bottom plate; the front end of the propulsion beam support is fixed with a tip; Hole drill propulsion beam, water mill drill propulsion beam; submersible drill propulsion beam is used to install submersible drilling system; water mill drill propulsion beam is used to install water mill drill system; The propulsion beam is provided with an opening and closing oil cylinder II; the opening and closing oil cylinder I and the opening and closing oil cylinder II are installed at the front end inside the propulsion beam support. The invention improves the drilling efficiency, and avoids the problem of emptying the empty surface around the tunnel face by using the down-the-hole drill alone and the problem of low drilling speed when the water mill drill is used alone to manufacture the empty surface around the tunnel face.

Description

technical field [0001] The invention belongs to the technical field of tunnel tunnel face drilling technology, and mainly relates to a hinged double propulsion beam propulsion mechanism. [0002] technical background [0003] At present, the technical requirements for the construction of urban underground tunnels are becoming more and more stringent. Therefore, the non-explosive construction method has been widely promoted and applied in the construction of urban underground tunnels. It has the characteristics of safety, environmental protection, and noise reduction. Among them, using a splitting rod to break the hard rock of the tunnel face is a very effective way. On the air side, the splitting stick can split the rock. Prior to this, the equipment for drilling the air surface included down-the-hole drills and water mill drills. The down-the-hole drills have a fast opening speed, but the disadvantage is that they cannot drill occlusal holes, because when drilling occlusal ...

Problems solved by technology

Before that, the drilling equipment for air surface includes down-the-hole drill and water grinding drill. The down-the-hole drill has a fast opening speed, but the disadvantage is that it cannot drill the occlusal hole, because when drilling the occlusal hole, part of the down-the-hole drill is not constrained by the rock. , which will make the down-the-hole drill shift towards the unconstrained direction, that is, channeling, so the down-the-hole drill can only drill holes with a certain hole spacing, and the undrilled rock between the holes can only rely on the water mill drill For coring, the water mill drill has stable drilling and less vibration. The disadvantage is that the drilling speed is slow, and each exchange between the down-the-hole drill and the water mill drill requires manual disassembly and assembly, resulting in low drilling efficiency and large labor investment.
