Embodiment 1

[0080] In view of the fact that the construction efficiency of the pile-anchor structure of the existing assembled subway station is low, the construction of the center column 11, the center longitudinal beam and the center plate needs to be carried out separately, and the application range is small. However, the construction of the pile-support structure has difficulty in cross-supporting and supports safety. In the case of hidden dangers, this embodiment is optimized to solve the problems existing in the prior art.

[0081] Specifically, such as figure 1 , figure 2 As shown, the present embodiment provides a trolley that can straddle the steel support and assemble the subway station, including several bottom assembling frames 2, the bottom assembling frame 2 is provided with a traveling mechanism 1; the bottom assembling frame 2 is provided with a Turn over the middle plate assembly mechanism 3 of the middle plate, and the bottom plate assembly frame is also provided with ...

Embodiment 2

[0088] The above-mentioned embodiment 1 discloses the overall structure of the trolley, and this embodiment optimizes and discloses the running mechanism 1 therein.

[0089] Such as Figure 3 ~ Figure 8 As shown, due to the large volume of the trolley, the force required by the traveling mechanism 1 to drive the trolley should be balanced and stable. The traveling mechanism 1 at the bottom of the trolley is used as a structure for driving the trolley, and can be set in a variety of ways that can stabilize the trolley. The driving structure is not uniquely limited, so it is optimized here and one of the feasible options is given: the number of the running gear 1 is several, and the running gear 1 includes a bottom track 6 formed by continuous splicing of several track standard sections, The bottom track 6 is provided with a pushing mechanism for promoting the bottom assembly frame 2 to walk and a guide device 9 for guiding the walking direction. When such a scheme is adopted, ...

Embodiment 3

[0101] This embodiment discloses the bottom assembly frame 2 used on the trolley.

[0102] Specifically, such as Figure 9 ~ Figure 12 As shown, the bottom assembly frame 2 used for assembling the bottom plate in this embodiment carries out the assembly and assembly of the bottom plate in the process of advancing, cooperates with the bottom rail 6 and advances along the bottom rail 6. In this embodiment, the bottom assembly machine The structure of the frame 2 is not uniquely limited, it is optimized here and a feasible option is given as follows: the bottom assembly frame 2 includes a number of lower longitudinal beams 10 that are connected with the running gear 1, and the upper side of the lower longitudinal beams 10 A column 11 is provided, and a platform structure 12 is provided at the top of the column 11 . When such a solution is adopted, the lower longitudinal beam 10 is used as a weight support, the column 11 is used as an extension of the height, and the platform str...

Abstract

The invention relates to the technical field of fabricated subway station construction, in particular to a trolley capable of crossing a steel support assembled subway station. The trolley comprises a plurality of bottom plate assembling racks; walking mechanisms are arranged at the lower parts of the bottom plate assembling racks; a middle plate assembling mechanism used for turning over a middle plate is arranged on each bottom plate assembling rack; a cross supporting mechanism is further arranged on each bottom plate assembling rack; each cross supporting mechanism comprises a rack body and an adjustable supporting mechanism connected with the rack body; the adjustable supporting mechanisms are connected with the bottom plate assembling racks and is fixedly connected with or separated from the rack bodies in an adjustable mode; and a top plate assembling mechanism is further arranged above the cross supporting mechanisms. The trolley capable of crossing the steel support assembled subway station can stride over a steel support structure in the advancing construction process, frequent assembly and disassembly are avoided, the efficiency of subway station splicing construction is greatly improved, meanwhile, supporting force is kept in the steel support striding process, and safety guarantee is improved.

Description

technical field [0001] The invention relates to the technical field of construction of a prefabricated subway station, in particular to a trolley capable of spanning steel supports and assembling a subway station. Background technique [0002] In the construction of the original open-cut subway station, the foundation pit of the subway station assembled with prefabricated components is reinforced with a pile-anchor structure. The interior of the foundation pit is open, and no steel support is required between the walls of the foundation pit. The subway station foundation pit in the form of pile-anchor structure is suitable for areas with relatively hard soil and rock strata, and its scope of application is limited, which is not conducive to national promotion. The assembly trolley in this construction process can only assemble the side wall and roof of the prefabricated components. The middle plate, central column and central longitudinal beam of the prefabricated components...
