Side cantilever tunnel self-propelled concrete maintenance vehicle

Abstract

The invention discloses an edge-on cantilever type self-traveling concrete curing vehicle for a tunnel, which comprises a main framework, a spraying maintenance device and a traveling device, wherein the main framework comprises a chassis frame, a support frame, a support frame bearing plate and a spraying arc arch frame; the spraying maintenance device comprises a self-priming pump, a steel water storage tank, a water pipe, a water sprinkling pipe and a nozzle; and the traveling device comprises a traveling track wheel mounting frame, a track wheel and a gear motor. The edge-on cantilever type self-traveling concrete curing vehicle is of an edge-on type, a bizarre design is carried out on the spraying arc arch frame, the requirements for normal ventilation of a ventilating pipe in a tunnel and traveling clearance are met, the vehicle travels along one side during operation in the tunnel, a traveling clearance for passing other engineering vehicles is reserved on the other side, the vehicle can be operated along with other working procedures simultaneously with no mutual interference generating, and the construction progress is guaranteed effectively; the vehicle adopts a hinged type chassis frame, and thus has stronger trafficability when the ground is uneven or a small barrier is on the ground; and the vehicle is provided with a crosswise limiting device in the traveling direction to guarantee that the curing vehicle does not deflect, and is equipped with an automatic traveling and time control device, so that a specially-assigned person is not required for guarding and control.

Description

technical field [0001] The invention relates to a side-standing cantilever type tunnel self-propelled concrete maintenance vehicle. Background technique [0002] With the stricter control of tunnel lining concrete construction quality standards, it is necessary to find new technologies, new processes or new equipment to meet the quality requirements of lining concrete maintenance. Traditional manual watering maintenance has the following disadvantages: First, there are artificial maintenance blind spots, manual cooperation The sprinkling of water pipes cannot be sprayed in place on some corners, resulting in maintenance blind spots; second, it is greatly affected by human factors. Due to the responsibility of operators and management problems, it is easy to cause the maintenance quality to fail to meet the design requirements and specification requirements. For example, insufficient maintenance time, Wet maintenance cannot be formed, and the maintenance does not operate acco...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the current tunnel concrete maintenance vehicles are of wide-body symmetrical structure. On the one hand, manpower or mechanical cooperation is required to move and walk; Section, the degree of automation is low; the third aspect, the walking trajectory is unstable, and the passability is poor when the ground is uneven or small obstacles, which affect the technical problems of spray maintenance efficiency and quality
