The length direction of the supporting arc plate 31 extends along the length direction of the underframe 1, and during use, the supporting arc plate 31 can be used for being attached to the outer wall of a shield body or the outer wall of a duct piece of the shield machine so as to support the shield body or a back support placed on the duct piece. The whole station transfer equipment is mainly suitable for shield type shield machines, such as shield type tunnel boring machines, slurry balance shield machines and earth pressure balance shield machines in TBMs.
From this, the equipment of changing station in this embodiment, the shield body and the back of shield formula shield structure machine are supported effectively through chassis 1 and support frame 3 to utilize the flexibility of universal wheel 2, can possess the straight line simultaneously and empty push, the side moves and the function of turning to, the function is more and easy operation, and then has increased the efficiency of construction, realizes changing the station fast, has effectively solved current equipment function singleness of crossing station, and the process is complicated, problem that the efficiency of construction is low.
In a specific implementation, the universal wheel 2 is preferably a self-driving universal wheel. The concrete structure of self-driven universal wheel is current structure, and self-driven universal wheel not only can 360 rotations by hydraulic drive, can also realize transferring in step to, and the efficiency of construction is higher.
In order to facilitate driving the supporting arc plate 31 to move up and down, as shown in fig. 2, each supporting frame 3 further includes a driving mechanism, a horizontal plate 32 and a plurality of triangular plates 33 vertically arranged on the plate surface, the horizontal plate 32 is arranged below the supporting arc plate 31, the plurality of triangular plates 33 are arranged at intervals along the length direction of the supporting arc plate 31 and clamped between the supporting arc plate 31 and the horizontal plate 32, the supporting arc plate 31, the triangular plates 33 and the horizontal plate 32 are fixedly connected to each other, and the driving mechanism is used for driving the horizontal plate 32 to move up and down.
