Description

TECHNICAL FIELD

[0001] The utility model relates to a tunnel construction equipment, especially a tunnel operation vehicle and a trestle. BACKGROUND

[0002] In recent years, tunnel construction technology in China has made great progress, and higher requirements are put forward for construction efficiency and quality. In the construction of tunnel inverted arch and side wall, various operations are often required on the operation platform, such as laying geotextile and waterproof board on both sides of the tunnel, laying cable on both sides of the tunnel, and installing inverted arch reinforcement. The existing operation platform mainly includes an automatic operation platform with an extension mechanical arm installed on the trestle trolley, and a simple operation platform fixed on the trestle trolley. The construction personnel can stand in the basket to work. The height of the simple operation platform fixed on the trestle trolley cannot be freely adjusted, and the simple support is set up at the bottom of the tunnel for construction operation. This method needs to manually move the support longitudinally (i.e. in the length direction of the tunnel), which is inconvenient to use.

[0003] Although the automatic operation platform with an extension mechanical arm can freely adjust the horizontal position and vertical height of the basket, it does not have the function of laying waterproof board / geotextile. The simple operation platform fixed on the trestle trolley also does not have the function of laying waterproof board / geotextile, and the height cannot be freely adjusted, which can only meet one kind of construction operation, and other construction operations are not suitable in height, affecting the construction efficiency. SUMMARY

[0004] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art, and to provide a tunnel operation vehicle with simple structure, convenient to use, and can be used for laying waterproof board / geotextile.

[0013] As a further improvement of the above technical solution: a telescopic guide rail is arranged on the telescopic platform, and a plurality of telescopic guide wheels are arranged on both sides of the telescopic guide rail.

[0014] As a further improvement of the above technical solution: a lifting support is arranged on the longitudinal moving trolley, a transition platform and an inclined ladder are arranged on the lifting support, the working platform is arranged on the side of the lifting support away from the longitudinal moving trolley, and the inclined ladder is arranged between the transition platform and the working platform.

[0015] As a further improvement of the above technical solution: the lifting support is an L-shaped support, the transition platform is arranged on the vertical part of the lifting support, the working platform is arranged on the horizontal part of the lifting support, and a maintenance area is formed below the transition platform and the inclined ladder.

[0016] A trestle bridge comprises a main bridge and the tunnel working vehicle, and the main bridge is provided with longitudinal moving guide rails on both sides in the transverse direction, and the longitudinal moving trolley is arranged on the longitudinal moving guide rails.
