Duct piece transporter for small-diameter shield machine and operating method of duct piece transporter

Abstract

The invention belongs to shield driving equipment, and particularly relates to a duct piece transporter for a small-diameter shield machine and an operating method of the duct pipe transporter. The duct piece transporter is characterized in that: the duct piece transporter, which consists of an electro-hydraulic push rod, a movable roller platform, roller platform rails and a towing shackle and is driven by the electro-hydraulic push rod, is arranged on a jogged duct piece inner bottom surface between a duct piece crane and a duct piece assembling machine; the electro-hydraulic push rod of the duct piece transporter is connected to a supporting frame at the tail ends of two rails, and the extension bar end of the duct piece transporter is hinged on a hinging seat at the tail part of the movable roller platform; the movable roller platform of the duct piece transporter consists of a roller set, a guide wheel and a wheel set, and the roller set consists of a side plate, a baffle plate and a roller; and an electric or manual towing shackle for connecting a lifting device is arranged in the middle of the baffle plate at the front end of the movable roller platform. The duct piece transporter is reasonable in design and compact in structure, realizes the transportation of secondary duct pieces, can automatically adjust the position of the roller platform, and has the advantages of easiness in manufacturing, expedite and smooth transportation, safety, reliability, high efficiency, energy conservation, less investment, convenience in operation and use and the like.

Description

technical field [0001] The invention belongs to shield tunneling equipment, in particular to a segment conveyor for small-diameter shield machines and an operating method thereof, which is suitable for transporting second-stage segments in small-diameter shield tunneling. 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. The second-stage segment conveying devices of the above two methods 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 component...

AI Technical Summary

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. The transportation device for the transportation of the secondary segment is very necessary
