Accumulating conveyor for shield segment

Abstract

The invention relates to a tube storage machine in shield construction, which comprises a movable platform, a support platform, a drawing hydraulic cylinder and several support hydraulic cylinders. Wherein, the support platform is arranged on the following bracket of shield construction; the movable platform is arranged on the support platform with moving front and back on the support platform; one end of drawing hydraulic cylinder is connected to the support platform while another end is connected to the movable platform; the support hydraulic cylinders are distantly fixed on two sides of the upper part of support platform. The invention uses mechanical transmission to replace traditional manned operation, uses the movable platform and several support hydraulic cylinders to realize the stepped frontward or backward transmission on the movable platform. The invention has high efficiency and safety.

Description

Technical field: [0001] The invention relates to a construction engineering machine for tunnel construction, in particular to a segment storage and transportation machine for shield tunneling used for tunnel construction. Background technique: [0002] At present, many municipal facilities need to be renovated and expanded. Especially with the large-scale construction of subways and highways, shield boring machines have become the preferred choice for tunnel excavation construction in such projects due to their advantages such as fast excavation speed and small impact on the surrounding environment. Machinery preferred. In the previous shield excavation construction, the double-beam mechanism is generally used to transport the tunnel segments, that is, two connecting beams welded by section steel are erected between the shield and the first frame at the rear of the shield. An electric hoist is installed on the parallel guide rails of the connecting beam. By manually operat...

AI Technical Summary

Problems solved by technology

However, the load capacity of the electric hoist of the double-beam mechanism is generally small, which can no longer meet the needs of lifting large tunnel segments; in addition, the double-beam mechanism can only lift one segment at a time. When the segment is in the wrong position, the segment assembly machine must rotate it 180° before assembling. This operation seriously reduces the construction efficiency; thirdly, the segment is also prone to safety hazards due to the shaking of the segment during hoisting and transportation. , causing construction accidents

Therefore, the segment transportation method of the double-beam mechanism is limited by its small bearing capacity, low construction efficiency and unsafe factors, and is no longer suitable for the transportation of large tunnel segments in shield construction.
