Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of tunnel excavation equipment, and specifically relates to a small-section water conservancy tunnel excavation trolley. BACKGROUND

[0002] In water conservancy construction, the trolley used for tunnel excavation is usually a scaffold or a construction trolley, and the scaffold is relatively difficult and cumbersome to move and disassemble multiple times. Moreover, due to the influence of the small space of the tunnel, the current construction process is to manually push the excavation trolley out of the tunnel first, and then manually push the trolley back into the tunnel for further excavation after the slag is cleaned. However, the existing excavation trolley is generally not equipped with an automatic walking device and relies on manual pushing and pulling to move, which is extremely inefficient. Moreover, the internal space of the tunnel is narrow and limited, and the construction platforms on both sides of the trolley will affect the trolley traffic and pose a potential threat to the construction safety of the tunnel, which not only affects the construction quality of the tunnel, but also easily increases the risk of safety hazards. Therefore, some construction units have developed self-propelled trolleys, such as:
