DETAILED DESCRIPTION

[0019] In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and are not an exhaustive list of all the embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other unless they conflict.

[0020] This embodiment provides a station assembly trolley suitable for assembling subway stations, improving construction efficiency and shortening construction period. The trolley can assemble double-layer stations, three-layer stations, four-layer stations, etc.

[0021] Figure 1 The figure shows a double-deck subway station. The station includes side wall blocks 91, center columns 92, center roof slabs 93, roof slabs 94, center longitudinal beams 95, top longitudinal beams 96, and bottom slabs 97. During construction, the platform's bottom slab 97 and the bottom longitudinal beam 98 located in the middle of the bottom slab 97 are first cast. The longitudinal direction is the length of the platform and also the direction of travel. Along the longitudinal direction, multiple side wall blocks 91 are sequentially spliced together to form the side walls. Multiple center columns 92 are arranged at intervals. Multiple center longitudinal beams 95 are sequentially spliced together, with each center longitudinal beam 95 overlapping two adjacent center columns 92. The center roof slabs 93 are transversely spliced between the side wall blocks 91 and the center longitudinal beams 95. Multiple center roof slabs 93 are sequentially spliced together along the longitudinal direction. The above-mentioned side wall blocks 91, center columns 92, center longitudinal beams 95, and center roof slabs 93 constitute the station's lower structure. After the lower structure is completed, the station's upper structure is constructed. The transverse direction is the direction from the side wall to the center column.

[0022] In the station's upper structure, upper center columns 92 are spaced longitudinally above the center longitudinal beams 95, and top longitudinal beams 96 are installed between adjacent upper center columns 92. Upper side wall blocks 91 are sequentially arranged on top of the lower side wall blocks 91, and top panels 94 are installed between the upper side wall blocks 91 and the top longitudinal beams 96. The top panels 94 are sequentially spliced longitudinally.

[0023] Figure 2 The station shown here is a three-story station. Similar to a two-story station, the station is divided into a top structure, a middle structure, and a bottom structure. The bottom structure is the same as the lower structure in a two-story station, while the middle and top structures refer to the upper structures in a two-story station, respectively.

[0024] like Figure 3As shown, the assembly trolley 10 is used to construct the lower structure. After the construction is completed or after the construction meets certain conditions, the assembly trolley 10 is used to construct the upper structure.

[0025] The station assembly trolley provided in this embodiment is particularly suitable for scenarios with steel temporary beams. The presence of the steel temporary beams precludes the use of gantry cranes for assembling the various structures. An open-air opening is provided at one end of the steel temporary beam, through which components are hoisted onto the trolley using a gantry crane. The trolley then allows the various structures to be transported and assembled autonomously beneath the steel temporary beam.

[0026] The station assembly trolley provided in this embodiment can be used to carry and assemble the center column in a scene with a steel beam. Figure 4 and Figure 5 As shown, the station assembly trolley provided in this embodiment includes: a main frame 1 and a center column installation device 2.

[0027] Wherein, main frame 1 serves as the main frame structure of trolley, and each component of trolley is all installed on main frame 1. The bottom end of main frame 1 is provided with running wheels, can walk on platform floor.

[0028] The center column mounting device 2 is located on one side of the main frame 1 and is used to secure the station center column and facilitate its transport and assembly. The center column mounting device 2 comprises a mobile platform mounted on the main frame 1 and capable of moving laterally relative to the main frame 1. The mobile platform has an opening that allows the center portion of the center column 92 to pass through. The opening is smaller than the top of the center column 92. The top of the center column 92 is larger than the center portion of the center column 92.

[0029] A gantry crane is used to lift the center column 92 from the opening at one end of the steel beam and lower it through the opening of the mobile platform. Because the opening is smaller than the top of the center column 92, the center column 92 can be clamped above the mobile platform, which supports the center column 92. As the trolley travels on the track, it carries the center column 92 to the assembly location for assembly.

[0030] The technical solution provided in this embodiment is that the trolley adopts a main frame and a center column installation device, and the center column installation device is arranged on one side of the main frame, and is used to fix the center column of the station and carry out transportation and assembly; the center column installation device includes: a mobile platform, which is arranged on the main frame and can be moved horizontally relative to the main frame; an opening is provided on the mobile platform for the middle part of the center column to pass through, and the opening is smaller than the top of the center column, which can realize the transportation and assembly of the center column. It is suitable for the scenario where a steel temporary beam is laid above, and is used to assemble the center column of the station, and can improve the assembly efficiency.

[0031] Based on the above technical solution, the middle cross section of the center column 92 is rectangular, and the cross section of the top of the center column 92 is also rectangular. The length of the middle cross section of the center column 92 is shorter than the length of the top cross section.

[0032] Regarding the center column 92, the mobile platform in this embodiment may specifically include two telescopic platforms 21 and an external limit assembly 22. The two telescopic platforms 21 are arranged parallel and side by side, and the distance between the two telescopic platforms 21 is greater than the length of the middle cross-section of the center column 92, and the distance between the two telescopic platforms 21 is less than the length of the top cross-section of the center column 92, so that the middle of the center column 92 can enter between the two telescopic platforms 21, and the center column 92 cannot fall through the gap between the two telescopic platforms 21, so that the two telescopic platforms 21 can support the center column 92 for piggyback transportation.

[0033] The outer limit assembly 22 is connected between the outer ends of the two telescopic platforms 21, and is used to limit the center column 92 from moving outward from the gap between the two telescopic platforms 21, preventing the center column 92 from falling out, thereby improving the stability and reliability of the center column 92 during the carrying process, and also helping to improve assembly efficiency.

[0034] Based on the above solution, this embodiment provides an implementation of an external limit assembly 22: the external limit assembly 22 includes a limit seat 226 and a limit beam 227. The limit seat 226 is arranged at the end of the telescopic platform 21, and is provided with a slot for accommodating the limit beam 227.

[0035] During the lifting process of the center column, the limiting beam 227 is removed from the limiting seat 226, and the passage between the two telescopic platforms 21 is opened, so that the center column enters between the two telescopic platforms 21. Then the limiting beam 227 is placed in the slots of the limiting seats 226 of the two telescopic platforms 21, so that the limiting beam 227 blocks the outside of the center column 92 to prevent the center column from falling out.

[0036] In one embodiment, the position limiting seat 226 is formed by welding a triangular steel plate and a square steel plate to form a set of position limiting members. The two position limiting members are arranged opposite each other, and a distance is left between them to accommodate the position limiting beam 227 as a slot. The position limiting beam 227 is a hollow steel beam with a rectangular cross section.

[0037] Based on the above scheme, this embodiment provides another implementation method of the external limit assembly 22: the external limit assembly includes: two flip arms 221, one end of the flip arm 221 is rotatably connected to the outer end of a telescopic platform 21, and the flip 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.

[0038] A specific implementation method: a flip arm 221 is connected to the telescopic platform 21 on the left side. Specifically, one end of the flip arm 221 is connected to the outer end of the telescopic platform 21 on the left side. The flip arm 221 can be rotated downward to extend to the right and extend into the gap between the two telescopic platforms 21; the flip arm 221 is rotated upward to be vertical.

[0039] Another flip arm 221 is connected to the telescopic platform 21 on the right side. Specifically, one end of the flip arm 221 is connected to the outer end of the telescopic platform 21 on the right side. The flip arm 221 can be rotated downward to extend to the left and extend into the gap between the two telescopic platforms 21; the flip arm 221 is rotated upward to be vertical.

[0040] Based on the above solution, one flip arm 221 is connected to each telescopic platform 21, and the two flip arms 221 rotate in the same vertical plane. When the two flip arms 221 rotate downward to the first position, the ends of the two flip arms 221 butt joint and close the gap between the two telescopic platforms 21, thereby restricting the center column 92 from moving outward from the gap between the two telescopic platforms 21. When the two flip arms 221 rotate upward to the second position, the gap between the two telescopic platforms 21 is connected to the outside, and the center column 92 can enter the gap between the two telescopic platforms 21 in this position.

[0041] During operation, the center column 92 is lifted by a gantry crane, and the two tilting arms 221 are rotated upward, so that the center column 92 enters the gap between the two telescopic platforms 21. The two tilting arms 221 are then rotated downward until they are aligned, completing the lifting of the center column 92. A trolley can then be used to carry the center column 92.

[0042] Based on the above technical solution, the external limit assembly 22 further includes a pulling assembly connected to the flip arm 221 for applying a rotational driving force to the flip arm 221. Specifically, the pulling assembly applies a pulling force to the flip arm 221, causing the flip arm 221 to rotate upward; when the pulling force of the pulling assembly disappears, the flip arm 221 rotates downward under the action of its own gravity.

[0043] One implementation method is: Figure 6 As shown, the pulling assembly includes: a wire wheel 222 and a wire wheel driving member, which are arranged at the outer end of the telescopic platform 21. A pulling wire 224 is wound around the wire wheel 222, and the pulling wire 224 is connected to the pull ring 2211 on the upper surface of the flip arm 221.

[0044] A reel driver is connected to the reel 222 and is used to provide rotational driving force to the reel 222. The reel driver can be manually driven or electrically driven. If manually driven, a crank can be provided on the reel 222 as the reel driver. An operator manually cranks the crank to rotate the reel 222, which in turn drives the tilting arm 221 upward via the pulley 224. If electrically driven, a motor can be used as the reel driver to drive the reel 222 to rotate.

[0045] In addition to the above technical solution, the pulling assembly may further include a pulley support column 225, vertically disposed at the outer end of the telescopic platform 21. A pulley 222 is rotatably mounted on the top of the pulley support column 225; the rotational axis of the pulley 222 is parallel to the length of the telescopic platform 21. Lifting the pulley 222 via the pulley support column 225 facilitates applying pulling force to the flip arm 221.

[0046] In addition to the above technical solution, the mobile platform further includes an inner limit assembly connected between the two telescopic platforms 21. A space is left between the inner limit assembly and the outer ends of the telescopic platforms 21 to accommodate the middle of the center column 92, thereby limiting the inward movement of the center column 92 within the gap between the two telescopic platforms 21.

[0047] One specific embodiment is as follows: the inner limit assembly is a steel plate connected between the two telescopic platforms 21, with a space between the outer end of the steel plate and the flip arm of the outer limit assembly 22 to accommodate the center column 92. The inner limit assembly can extend or retract laterally along with the two telescopic platforms 21.

[0048] Based on the above technical solution, the mobile platform further includes: a first clamping assembly 24, which is provided on the side of the telescopic platform 21 facing the other telescopic platform 21. The first clamping assembly 24 is provided on both telescopic platforms 21, and is used to contact the center column 92 and apply a clamping force to the center column 92 to prevent the center column 92 from moving during the carrying process.

[0049] One approach is to have the first clamping assembly 24 comprise a clamping driver 241 and a clamping head 242. The clamping driver is secured 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, with the first clamping assemblies 24 on two telescopic platforms 21 facing each other.

[0050] The clamping driver 241 drives the clamping heads 242 to move closer to each other to clamp the center column; and releases the center column when the clamping heads 242 move away from each other.

[0051] In another embodiment, the first clamping assembly includes a first clamping plate and a first clamping member. The first clamping plate is vertically positioned on the side of the telescopic platform 21 facing the other telescopic platform 21. The first clamping member is mounted on the first clamping plate and is movable relative to the first clamping plate in a direction perpendicular to the first clamping plate. The first clamping members on the two telescopic platforms 21 move toward each other, applying a clamping force to the center column 92.

[0052] Furthermore, the first clamping assembly also includes: a first clamping pad, which is provided at the end of the first clamping member, and is used to contact the center column 92 and has a buffering ability to avoid scratches and other damages to the surface of the center column 92.

[0053] Based on the above technical solution, the inner limit assembly is provided with a second clamping assembly 25, which extends in a direction perpendicular to the first clamping assembly 24 and is used to clamp the center column from the inside. The specific implementation of the second clamping assembly 25 can refer to the first clamping assembly 24.

[0054] Specifically, the second clamping assembly 25 also adopts the solution of the clamping driver 241 and the clamping head 242, or adopts the solution of the first clamping plate and the first clamping member.

[0055] Based on the above technical solutions, this embodiment further provides a station assembled using any of the above-mentioned station assembly trolleys. The station includes side wall blocks 91, center columns 92, center top plates 93, top plates 94, center longitudinal beams 95, top longitudinal beams 96, and bottom plates 97.

[0056] The station provided in this embodiment has the same technical effect as the above-mentioned station assembly trolley.
