[0001] This application relates to construction technology for underground railway stations, and more particularly to a station assembly trolley and trolley for assembling the central columns of a station. Background Technology

[0002] The construction of subway stations is an important part of subway lines. The traditional method of all-concrete cast-in-place construction can no longer meet the requirements of efficient construction. There is an urgent need for a technical solution that can achieve rapid, efficient and high-quality completion of subway station construction.

[0003] In addition, gantry cranes can be used to lift various components during open-cut construction. However, in some cases where it is necessary to lay temporary steel beams to avoid affecting ground traffic, gantry cranes cannot be used for lifting, which causes great inconvenience to the construction of subway stations.

[0049] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0050] This embodiment provides a station assembly trolley, suitable for assembling subway stations, improving construction efficiency and shortening the construction cycle. This trolley can assemble double-layer, triple-layer, or quadruple-layer stations, etc.

[0051] Figure 1The diagram shows a two-level subway station, comprising: side wall blocks 91, central columns 92, central roof slab 93, roof slab 94, central longitudinal beams 95, top longitudinal beams 96, and a base slab 97. During construction, the base slab 97, forming the platform, and the bottom longitudinal beam 98 located in the center of the base slab 97 are poured first. The longitudinal direction represents the length of the platform and also the direction of train travel. Along the longitudinal direction, multiple side wall blocks 91 are sequentially assembled to form side walls, multiple central columns 92 are spaced apart, and multiple central longitudinal beams 95 are sequentially assembled, with each beam overlapping an adjacent central column 92. The central roof slab 93 overlaps laterally between the side wall blocks 91 and the central longitudinal beams 95, and multiple roof slabs 93 are sequentially assembled longitudinally. These side wall blocks 91, central columns 92, central longitudinal beams 95, and central roof slabs 93 constitute the lower structure of the station. After the lower structure is completed, the upper structure of the station is constructed. The transverse direction is from the side walls to the central columns.

[0052] In the upper structure of the station, upper-level central columns 92 are set longitudinally at intervals above the central longitudinal beam 95, and then top longitudinal beams 96 are set between adjacent upper-level central columns 92. Upper-level side wall blocks 91 are arranged sequentially on top of lower-level side wall blocks 91, and top plates 94 are set between the upper-level side wall blocks 91 and the top longitudinal beams 96. The top plates 94 are spliced ​​together longitudinally.

[0053] Figure 2 This shows a three-level station. Similar to a double-decker station, the station is divided into a top-level structure, a middle-level structure, and a bottom-level structure. The bottom-level structure is the same as the lower-level structure in a double-decker station, while the middle-level and top-level structures refer to the upper-level structures in a double-decker station.

[0054] like Figure 3 As shown, the assembly trolley 10 is used to construct the lower structure. After the construction is completed or after certain conditions are met, the assembly trolley 10 is used to construct the upper structure.

[0055] The station assembly trolley provided in this embodiment is particularly suitable for scenarios with steel temporary beams. The presence of the steel temporary beams prevents the use of gantry cranes to assemble the various structures. An open-air opening is provided at one end of the steel temporary beam, through which a gantry crane is used to hoist the components onto the trolley. The trolley then enables the self-carrying and assembly of the various structures under the steel temporary beam.

[0056] The station assembly trolley provided in this embodiment can be used to transport and assemble central columns in scenarios with steel temporary beams. Specifically, as follows... Figure 4 and Figure 5 As shown, the station assembly trolley provided in this embodiment includes: a main frame 1 and a central column mounting device 2.

[0057] The main frame 1 serves as the main framework of the trolley, and all components of the trolley are mounted on the main frame 1. The bottom of the main frame 1 is equipped with wheels, allowing it to travel on the platform floor.

[0058] The central column mounting device 2 is located on one side of the main frame 1 and is used to fix the station's central column and for transporting and assembling it. The central column mounting device 2 includes a movable platform, mounted on the main frame 1, which can move laterally relative to the main frame 1. The movable platform has an opening through which the middle of the central column 92 can pass, the opening being smaller than the top of the central column 92. The top of the central column 92 is larger than the middle of the central column 92.

[0059] At the opening at one end of the steel temporary beam, the central column 92 is lifted by a gantry crane and passed through the opening of the mobile platform from top to bottom. Because the opening is smaller than the top of the central column 92, the central column 92 can be secured above the mobile platform, which supports it. As the trolley moves along the track, the central column 92 is transported to the assembly position for assembly.

[0060] The technical solution provided in this embodiment uses a main frame and a central column installation device on the trolley. The central column installation device is located on one side of the main frame and is used to fix the central column of the station and to carry and assemble it. The central column installation device includes a mobile platform, which is set on the main frame and can move laterally relative to the main frame. The mobile platform has an opening through which the middle part of the central column can pass. The opening is smaller than the top of the central column, which enables the carrying and assembly of the central column. It is suitable for scenarios where steel temporary beams are laid above, and is used to assemble the central column of the station, thereby improving the assembly efficiency.

[0061] Based on the above technical solution, the central cross-section of the central column 92 is rectangular, and the top cross-section of the central column 92 is also rectangular. The length of the central cross-section of the central column 92 is less than the length of the top cross-section.

[0062] Regarding the aforementioned central column 92, the mobile platform in this embodiment may specifically include two telescopic platform plates 21 and an outer limiting component 22. The two telescopic platform plates 21 are arranged parallel and side-by-side. The distance between the two telescopic platform plates 21 is greater than the length of the middle cross-section of the central column 92, and less than the length of the top cross-section of the central column 92. This allows the middle part of the central column 92 to enter between the two telescopic platform plates 21, and prevents the central column 92 from falling through the gap between the two telescopic platform plates 21, thus enabling the two telescopic platform plates 21 to support the central column 92 for transport.

[0063] The outer limiting component 22 is connected between the outer ends of the two telescopic platforms 21 to restrict the central column 92 from moving outward from the gap between the two telescopic platforms 21, thereby preventing the central column 92 from falling out and improving the stability and reliability of the central column 92 during the transportation process, and also helping to improve assembly efficiency.

[0064] Based on the above solution, this embodiment provides an implementation method for an external limiting component 22: the external limiting component 22 includes a limiting seat 226 and a limiting beam 227. The limiting seat 226 is disposed at the end of the telescopic platform 21, and the limiting seat 226 is provided with a slot for accommodating the limiting beam 227.

[0065] During the hoisting of the central column, the limiting beam 227 is removed from the limiting seat 226, opening the channel between the two telescopic platforms 21, allowing the central column to enter between the two telescopic platforms 21. Then, the limiting beam 227 is placed in the slot of the limiting seat 226 of the two telescopic platforms 21, so that the limiting beam 227 blocks the outside of the central column 92, preventing the central column from detaching.

[0066] One specific implementation: The limiting seat 226 is a set of limiting components welded from triangular and square steel plates. The two limiting components are arranged opposite to each other, and a gap is left between them to accommodate the limiting beam 227 as a slot. The limiting beam 227 is a hollow steel beam with a rectangular cross-section.

[0067] Based on the above scheme, this embodiment provides another implementation of the outer limiting component 22: the outer limiting component includes two flipping arms 221, one end of which is rotatably connected to the outer end of a telescopic platform 21. The flipping arm 221 can rotate relative to the telescopic platform 21 in a vertical plane, rotating downward to a first position extending toward the other telescopic platform 21 or rotating upward to a second position extending upward.

[0068] One specific implementation: A flip arm 221 is connected to the left telescopic platform 21. Specifically, one end of the flip arm 221 is connected to the outer end of the left telescopic platform 21. The flip arm 221 can rotate downward to extend to the right and extend into the gap between the two telescopic platforms 21; the flip arm 221 can rotate upward to the vertical position.

[0069] Another tilting arm 221 is connected to the right telescopic platform 21. Specifically, one end of the tilting arm 221 is connected to the outer end of the right telescopic platform 21. The tilting arm 221 can rotate downward to extend to the left and into the gap between the two telescopic platforms 21; the tilting arm 221 can rotate upward to the vertical position.

[0070] Based on the above scheme, one flipping arm 221 is connected to one telescopic platform 21, and the two flipping arms 221 rotate in the same vertical plane. When the two flipping arms 221 rotate downward to the first position, the ends of the two flipping arms 221 are joined together and close the gap between the two telescopic platforms 21, so as to restrict the central column 92 from moving outward from the gap between the two telescopic platforms 21; when the two flipping arms 221 rotate upward to the second position, the gap between the two telescopic platforms 21 is connected to the outside, and the central column 92 can enter the gap between the two telescopic platforms 21 in this position.

[0071] During operation, the central column 92 is lifted by a gantry crane, and the two tilting arms 221 are rotated upwards, allowing the central column 92 to enter between the two telescopic platforms 21 through the gap. Then, the two tilting arms 221 are rotated downwards until they align, completing the lifting of the central column 92. A subsequent trolley can then carry the central column 92.

[0072] Based on the above technical solution, the outer limiting component 22 further includes a traction component connected to the tilting arm 221, used to apply a rotational driving force to the tilting arm 221. Specifically, the traction component applies a traction force to the tilting arm 221, causing the tilting arm 221 to rotate upward; when the traction force of the traction component disappears, the tilting arm 221 rotates downward under its own gravity.

[0073] One implementation method is as follows: Figure 6 As shown, the pulling assembly includes a spool 222 and a spool drive, which are located at the outer end of the telescopic platform 21. A pulling line 224 is wound around the spool 222, and the pulling line 224 is connected to a pull ring 2211 on the upper surface of the tilting arm 221.

[0074] The spool drive is connected to the spool 222 and provides rotational driving force to the spool 222. The spool drive can be manually driven or electrically driven. If manually driven, a crank can be installed on the spool 222 as the spool drive; the operator holds the crank to rotate the spool 222, which in turn drives the tilting arm 221 to swing upwards via the pull line 224. If electrically driven, a motor can be used as the spool drive to rotate the spool 222.

[0075] Based on the above technical solution, the traction assembly may further include a sheave support column 225, which is vertically disposed at the outer end of the telescopic platform 21. A sheave 222 is rotatably disposed at the top of the sheave support column 225; the rotation center line of the sheave 222 is parallel to the length direction of the telescopic platform 21. Raising the sheave 222 via the sheave support column 225 facilitates the application of traction force to the tilting arm 221.

[0076] Based on the above technical solution, the mobile platform also includes an inner limiting component connected between the two telescopic platform plates 21. A space is left between the inner limiting component and the outer end of the telescopic platform plate 21 to accommodate the middle part of the central column 92, thereby restricting the inward movement of the central column 92 within the gap between the two telescopic platform plates 21.

[0077] One specific method is as follows: the inner limiting component is a steel plate connected between two telescopic platforms 21, and a space is left between the outer end of the steel plate and the flip arm in the outer limiting component 22 to accommodate the central column 92. The inner limiting component can extend or retract laterally together with the two telescopic platforms 21.

[0078] Based on the above technical solution, the mobile platform further includes: a first clamping assembly 24, disposed on the side of the telescopic platform 21 facing the other telescopic platform 21. Both telescopic platforms 21 are provided with the first clamping assembly 24, which is used to contact the central column 92 and apply clamping force to the central column 92 to prevent it from moving during transport.

[0079] One embodiment is as follows: the first clamping assembly 24 includes a clamping driver 241 and a clamping head 242. The clamping driver is fixed to the telescopic platform 21 via a clamping base 243, and the clamping head 242 is located at the output end of the clamping driver 241. Each telescopic platform 21 is provided with a first clamping assembly 24, and the first clamping assemblies 24 on two telescopic platforms 21 are arranged facing each other.

[0080] The clamping driver 241 drives the clamping heads 242 to move closer together to clamp the central column; when they move away from each other, the central column is released.

[0081] Another embodiment is as follows: The first clamping assembly includes a first clamping plate and a first clamping member. The first clamping plate is vertically disposed on the side of the telescopic platform 21 facing the other telescopic platform 21. The first clamping member is disposed on the first clamping plate and is movable relative to the first clamping plate in a direction perpendicular to the first clamping plate. The movement of the first clamping members on the two telescopic platforms 21 towards each other applies a clamping force to the central column 92.

[0082] Furthermore, the first clamping assembly also includes a first clamping pad, disposed at the end of the first clamping member, for contacting the central column 92 and having a buffering capacity to avoid scratches or other damage to the surface of the central column 92.

[0083] Based on the above technical solution, a second clamping component 25 is provided on the inner limiting component. The second clamping component 25 extends in a direction perpendicular to the first clamping component 24 and is used to clamp the central column from the inside. The specific implementation of the second clamping component 25 can be referred to the first clamping component 24.

[0084] Specifically, the second clamping assembly 25 may also adopt a clamping driver 241 and a clamping head 242, or a first clamping plate and a first clamping member.

[0085] Based on the above technical solutions, this embodiment also provides a station, which is assembled using the station assembly trolley provided in any of the above contents. The station includes: side wall blocks 91, central columns 92, central roof slab 93, roof slab 94, central longitudinal beams 95, top longitudinal beams 96, and a base slab 97.

[0086] The station provided in this embodiment has the same technical effect as the station assembly trolley described above.
