Problems solved by technology

The problem with the existing bolt trolley is that the construction efficiency is too low, which seriously slows down the construction period, and the efficiency is improved by adding equipment, and there are problems of insufficient site layout space and high cost
However, the construction efficiency of the equipment is still not enough to meet the demand
Anchor drilling into a single hole is not cost-effective

Embodiment Construction

[0033] Such as Figure 1~6 Among them, a tunnel bolt construction trolley, comprising a trolley frame 1, on which a plurality of rock bolt drilling rigs are arranged;

[0034] The rock bolter includes at least a mechanical arm with two joints, and the drilling mechanism 31 is installed on the top of the mechanical arm; since the platform frame is customized according to the size of the tunnel, the mechanical arm with two joints is set, Realizing the pitching operation can satisfy the basic bolt positioning construction. Due to the reduction of the joints, the stiffness of the mechanical arm is also increased correspondingly, which is beneficial to reduce the cost. A joint in this case is a moving part that can move in at least one constrained direction and be constrained in other constrained directions. Such as hinged structure and horizontal rotation structure. The number of joints in this example is preferably no more than 4.

[0035] The rock bolt includes one or more of...

Abstract

The invention provides a tunnel anchor construction trolley which comprises a trolley frame which is provided with a plurality of anchor drills. Each of the anchor drills at least comprises a mechanical arm provided with two joints, and a drilling mechanism is installed at the top end of the mechanical arm. The anchor drills comprise one or more drills of translational anchor drills, fixed anchordrills, and swing anchor drills. By setting the multiple anchor drills in one trolley frame and using a structure with the combination of the translational anchor drills, the fixed anchor drills and the swing anchor drills according to the site conditions, the simultaneous construction of the multiple anchor drills can be achieved, and the construction efficiency is greatly improved. Since the structure of a single anchor drill is greatly simplified, especially an expensive running mechanism is omitted, and the cost performance of drilling a single hole by the anchor drill is greatly improved.

Description

technical field [0001] The invention relates to the field of tunnel support construction equipment, in particular to a tunnel bolt construction trolley. Background technique [0002] During tunnel excavation, the geological conditions of some surrounding rocks require surrounding rock support construction to avoid problems such as vault sinking and rock mass shedding. And wet spray lining construction is a necessary step. [0003] In the bolt construction in the prior art, a bolt trolley is usually driven by hydraulic pressure to drive the hollow bolt into the surrounding rock through rotation and impact. The usual bolt trolley includes a tire or crawler base. The problem existing in the existing bolt trolley is that the construction efficiency is too low, which seriously slows down the construction period, and the efficiency is improved by adding equipment, and there are problems of insufficient site layout space and high cost.
