Abstract

The invention discloses a self-propelled tunnel maintenance vehicle, which comprises a second-class chassis of a car, a sub-frame, a self-propelled device and an operating device. The sub-frame is connected to the second-class chassis of the car. The self-propelled device includes a The four outriggers at the bottom of the sub-frame are connected to the movable legs through the oil cylinder, and the traveling wheels are installed on the bottom of the movable legs; the working device is a multi-platform foldable working device, including a horizontal and vertical Multiple operating platforms, the expanded state of the multiple operating platforms can cover a quarter of the circular arc surface, and the maintenance vehicle can realize low-speed and controllable walking speed during construction operations, which solves the problem of the current tunnel maintenance work. There are a series of problems such as non-adjustable range, point-to-point operation, low carrying capacity of the operation bucket, inability to walk during operation, road occupation during operation, low operation efficiency and low safety.

Description

Technical field [0001] The present invention relates to a self-propelled tunnel maintenance operation vehicle, belonging to the field of tunnel maintenance technology. Background [0002] With the progress of science and technology, the number of road tunnels is increasing, and even the growth rate of tunnels is higher than the growth rate of highways themselves. The tunnel is limited by geological conditions, design and construction technology, and there are many problems. Judging from the road tunnels that have been built, the phenomena of water leakage, cracking of the lining, hollow arch back, insufficient thickness of the lining, and deterioration of the strength of the concrete are more serious. At present, some road tunnels are in a sub-healthy state of disease development, and many tunnels have entered the maintenance and repair period. Common tunnel maintenance contents include: civil engineering maintenance (lining cracking, water leakage, etc.); lighting, ventilation,...
