Segment transportation device and operation method for shield tunneling with tunnel diameter less than six meters

Abstract

The invention belongs to shield excavating equipment, and relates to a duct piece conveying device for the shield construction of a tunnel with the diameter of less than 6 meters and an operation method. The duct piece conveying device is characterized in that: a duct piece conveyor consisting of a crane combination driving mechanism, a duct piece bearing roller platform and a support mechanism is arranged on the inner bottom surface of the tunnel; the crane combination driving mechanism consists of a front dragging machine consisting of a hoist crane and a fixed pulley and a rear pulling mechanism consisting of a duct piece crane and a hanging joint rigging; the duct piece bearing roller platform is driven by the crane combination driving mechanism, so that duct pieces are conveyed to a duct piece splicer to be spliced; and the duct piece bearing roller platform is a sliding bearing roller platform, a wheel set bearing roller platform or a rail bearing roller. The duct piece conveying device has reasonable design and a compact structure, is suitable for the conveying operation of the duct pieces in low space and adjusting the self-position, has the advantages of continuous conveying, smooth and stable running, safety, reliability, high efficiency, energy conservation, small investment, convenience for operation and use and the like.

Description

technical field [0001] The invention belongs to shield tunneling equipment, in particular to a segment transport device and an operation method suitable for shield tunnel construction with a diameter of less than six meters. Background technique [0002] At present, in the construction of shield tunnels with a diameter of 6 meters and above, due to the large construction diameter, most of them adopt the sequential transportation method of two-stage segment cranes or the two-stage sequential transportation of segment cranes and segment feeders. In the above two methods, the secondary segment conveying devices have complex structures and large dimensions. One of the patent searches: Patent No. ZL200610025190.8 Segment storage and transportation machine for shield tunneling. The segment storage and transportation machine includes mobile platform, support platform, traction mechanism and jacking cylinder group and other components, and its structural size is relatively large. ,...

Problems solved by technology

With the rapid development of urbanization, more and more small-diameter shield construction projects with a diameter of less than 6 meters are used for the development of common trenches for urban pipelines. In small-scale shield construction, the space for segment transportation and picking is limited , can not accommodate complex mechanisms such as two-stage segment cranes or segment feeders, and the efficiency of manually transporting segments is low. Segment transportation device for construction is very necessary
