Abstract

The invention provides a narrow-wheelspan duct piece transportation vehicle, which relates to equipment for transporting duct pieces used for tunnels and aims at solving the problem to realize transportation of the duct pieces in the tunnels. The narrow-wheelspan duct piece transportation vehicle comprises cabs, a distance measuring sensor, a vehicle frame in a shape like a Chinese character 'ao', the duct pieces, a rubber pad block, a steel duct piece fixing device, an electric control cabinet, an engine, a hydraulic power group, a rotary supporter, a rotary driving device and four walking wheel groups, wherein the four walking wheel groups are of different structures, the vehicle frame in the shape like the Chinese character 'ao' forms a support part of the narrow-wheelspan duct piece transportation vehicle with the rotary supporter and the four walking wheel groups positioned under the vehicle frame, the head and tail two-directional cabs enable the four walking wheel groups to realize the driving and flexible steering through the control on the engine, the hydraulic power group and the electric control cabinet, and the duct piece fixing device arranged on the vehicle frame in the shape like the Chinese character 'ao' is used for fixing the carried duct pieces. Through the design of narrow wheelspan and a long vehicle body and adoption of a vehicle meeting system, the safe vehicle meeting and the safe duct piece transportation of the narrow-wheelspan duct piece transportation vehicle in the tunnels can be realized.

Description

technical field [0001] The invention relates to equipment for transporting segments for tunnels, in particular to a segment transport vehicle with narrow wheel base. Background technique [0002] With the rapid urbanization of our country, there are more and more tunnel projects such as subways and underground passages in many cities. In the current construction process, automatic excavation equipment such as shields is generally used to excavate tunnels. After the tunnels are completed, prefabricated tunnels are required. The cement segment is laid on the inner wall of the tunnel as the structure of the tunnel support system. In engineering, the prefabricated cement segment inner wall laying technology is generally used, that is, the inner wall of the tunnel support is assembled in blocks and segments of prefabricated cement segments one ring after another. A ring of the tunnel section is generally composed of 4 to 12 pieces assembled, while The length of each ring is gene...
