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
[0005] In the grouting process, a special high-pressure grouting vehicle is usually used, but the commonly used high-pressure grouting vehicle is mainly used for flat construction, and it is inconvenient to use in the tunnel construction process

Embodiment Construction

[0038] Such as Figure 1~6 Among them, a trolley for tunnel bolt grouting construction, including a trolley frame 1, on which a plurality of rock bolt drilling rigs are arranged;

[0039] 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.

[0040] The rock bolt includes on...

Abstract

The invention provides a tunnel anchor rod grouting construction trolley which comprises a trolley frame, wherein a plurality of anchor rod drilling machines are arranged on the trolley frame. The anchor rod drilling machines at least comprise mechanical arms each with two joints, and drilling mechanisms are mounted at the top ends of the mechanical arms. The anchor rod drilling machines compriseone or more of a horizontal moving type anchor rod drilling machine, a fixed type anchor rod drilling machine and a swing type anchor rod drilling machines. The tunnel anchor rod grouting constructiontrolley is further provided with a grouting trolley which is connected with the trolley frame. A stirring tank is arranged on the grouting trolley and connected with a grouting pump, wherein the grouting pump is connected with a grouting pipe. The multiple anchor rod drilling machines are arranged on one trolley frame, and the multiple anchor rod drilling machines can carry out construction at the same time, so that the efficiency of construction is greatly improved. Matched grouting construction can be realized through the arrangement of the grouting trolley, and the efficiency of the integral construction is greatly improved.

Description

technical field [0001] The invention relates to the field of tunnel support construction equipment, in particular to a tunnel bolt grouting 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.
