Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of segment transportation technology, and specifically relates to a rail-mounted electric segment transport vehicle. BACKGROUND

[0002] In the field of shield construction such as tunnels, subways and underground pipe galleries, segments as the main supporting structure have various transportation modes. At present, common segment transportation modes mainly include railless transportation and rail-mounted transportation. Railless transportation mainly relies on forklifts, flatbed trucks or dump trucks for short-distance handling, but such modes have problems of being greatly affected by ground conditions, being inconvenient to transfer and being low in transportation stability. Rail-mounted transportation widely adopts rail-mounted electric transport vehicles, fixed tracks are laid to make segments have better directional control ability in the transportation process, and to reduce the problems of inclination or falling caused by uneven ground or turning. Compared with railless transportation, rail-mounted transportation has fixed running routes and strong load capacity, and therefore becomes the mainstream mode for long-distance handling of segments in current tunnel shield construction.

[0003] However, in the existing rail-mounted segment transportation process, the conventional transportation mode mainly relies on simple supporting structures or binding methods for segment fixation, and it is difficult to effectively prevent the segments from shaking, slipping or overturning in the transportation process. In addition, due to factors such as vibration, emergency braking or turning in the transportation process, the segments are prone to displacement, affecting the overall stability, and there are problems of unstable segment fixation, poor overall stability and potential safety hazards in the transportation process.
