Detailed Implementation

[0032] 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.

[0033] 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.

[0034] Figure 1 The image 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. The aforementioned side wall blocks 91, central columns 92, central longitudinal beams 95, and central roof slab 93 constitute the lower structure of the station. After the lower structure is completed, the upper structure of the station is constructed.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] like Figures 4 to 11 As shown, the station assembly trolley provided in this embodiment includes: a wheel-rail running device 1, a frame 2, a side wall mounting device 3, a longitudinal beam mounting device 4, and a top plate mounting device 5.

[0040] The wheel-rail traveling device 1 is located at the bottom of the frame 2 and can travel along the tracks on the platform floor. Specifically, after the floor 97 is formed, temporary tracks are laid on both sides of the bottom longitudinal beam 98 on the floor 97, with the tracks extending longitudinally. The wheel-rail traveling device 1 travels along the tracks on the floor 97, allowing the trolley to move longitudinally and be assembled step by step. The frame 2 is located above the wheel-rail traveling device 1 and serves as the main frame structure of the trolley; all components of the trolley are mounted on the frame 2.

[0041] The side wall mounting device 3 is mounted on the frame 2. At the open-air opening, the side wall block 91 is lifted by a gantry crane onto the side wall mounting device 3. The side wall mounting device 3 fixes the side wall block 91 and moves it to the side wall mounting position for assembly. In this embodiment, the platform side wall includes multiple side wall blocks 91, which are arranged longitudinally to form the station's side wall. During construction, the trolley travels longitudinally, assembling the side wall blocks 91 sequentially.

[0042] The longitudinal beam installation device 4 is mounted on the frame 2 and is used to fix the longitudinal beam and move it to the target position for assembly. The gantry crane lifts the longitudinal beam onto the trolley at the open-air opening. The trolley travels along the track, carrying the longitudinal beam, and assembles it at the target position. During construction, the trolley travels longitudinally, assembling the longitudinal beams sequentially.

[0043] The roof plate installation device 5 is mounted on the frame 2 to support the roof plate and move it to the target position for assembly. The gantry crane lifts the longitudinal beams onto the trolley at the open-air opening. The trolley travels along the track, carrying the longitudinal beams, and assembles them at the target position. During construction, the trolley travels longitudinally, assembling the longitudinal beams sequentially.

[0044] The technical solution provided in this embodiment includes a station assembly trolley comprising: a wheel-rail traveling device, a frame, a side wall mounting device, a longitudinal beam mounting device, and a roof plate mounting device. The wheel-rail traveling device is located at the bottom of the frame and can travel along the track on the platform floor. The side wall mounting device is mounted on the frame and is used to fix the side wall blocks and move them to the side wall mounting position for assembly. The longitudinal beam mounting device is mounted on the frame and is used to fix the longitudinal beams and move them to the target position for assembly. The roof plate mounting device is mounted on the frame and is used to support the roof plate and move it to the target position for assembly. This solution is suitable for scenarios where steel temporary beams are laid above the station, utilizing the trolley to transport and assemble the side wall blocks, longitudinal beams, and roof plate, and has high construction efficiency.

[0045] Based on the above technical solutions, this embodiment provides an implementation method for the sidewall mounting device 3: like Figure 5 As shown, the sidewall mounting device 3 includes a sidewall support mechanism 31, a sidewall mounting mechanism 32, and a sidewall fine-tuning mechanism 33. The sidewall support mechanism 31 is located at the lower part of the frame 2 and extends to one side of the frame 2, specifically towards the direction where the sidewall will be assembled. A gantry crane lifts the sidewall block 91 onto the sidewall support mechanism 31, which supports the sidewall block 91 from the bottom.

[0046] The side wall mounting mechanism 32 is located on the top of the frame 2. When the gantry crane lifts the side wall block 91 onto the side wall support mechanism 31, the side wall mounting mechanism 32 is connected to the side wall block 91. The side wall mounting mechanism 32 is used to apply a pushing force to the side wall block 91 to move the side wall block 91 and achieve assembly.

[0047] The side wall fine adjustment mechanism 33 is located at the lower part of the frame 2 and is used to apply force to the lower part of the side wall block 91 to finely adjust the pitch angle of the side wall block 91.

[0048] The station assembly trolley provided in this embodiment includes: a wheel-rail traveling device, a frame, and a side wall mounting device; the wheel-rail traveling device is located at the bottom of the frame and can travel along the track on the platform floor; the side wall mounting device is located on the frame and is used to fix the side wall blocks and move the side wall blocks to the side wall mounting position for assembly; the side wall mounting device includes: a side wall support mechanism, located at the bottom of the frame and extending to one side of the frame, for supporting the side wall blocks from the bottom; a side wall mounting mechanism, located at the top of the frame, for applying a pushing force to the side wall blocks to move the side wall blocks and achieve assembly; and a side wall fine-tuning mechanism, located at the bottom of the frame, for applying a force to the bottom of the side wall blocks to finely adjust the pitch angle of the side wall blocks, thereby assembling the side walls of the station and solving the problems of low efficiency and poor quality in cast-in-place construction.

[0049] Furthermore, the above solution uses a side wall support mechanism to support the side wall blocks, a side wall installation mechanism to apply a pushing force to the side wall blocks to move them and achieve assembly, and a side wall fine-tuning mechanism to finely adjust the pitch angle of the side wall blocks, which can ensure stable installation of the side wall blocks and improve accuracy, thereby improving the assembly quality.

[0050] Based on the above technical solution, the side wall mounting device 3 further includes a side wall clamping mechanism 34. The side wall clamping mechanism 34 is located in the middle of the frame 2, extends from both sides of the side wall block 91 to the side of the side wall block 91 away from the trolley, and applies clamping force to the side wall block 91 to prevent the side wall block 91 from tipping over during movement.

[0051] This embodiment provides an implementation method: the side wall mounting device 3 is located on one side of the frame 2, specifically the side close to the side wall to be assembled. The side wall block 91 is lifted onto the side wall mounting device 3 by a gantry crane, and the side wall mounting mechanism 32 moves the side wall block 91 into position for assembly by moving it in the horizontal, longitudinal and vertical directions.

[0052] For the side wall support mechanism 31, this embodiment provides a specific example: such as Figure 7 As shown, the side wall support mechanism 31 includes at least two side wall support beams 311, which extend laterally. The at least two side wall support beams 311 are arranged longitudinally at intervals. Side wall blocks 91 are placed on each side wall support beam 311, and each side wall support beam 311 supports the side wall blocks 91.

[0053] The side wall support beam 311 can be a steel beam with a U-shaped cross section, an I-shaped steel beam, or a steel beam of other shapes.

[0054] Furthermore, the upper surface of the side wall support beam 311 is flat, and the upper surfaces of each side wall support beam 311 are at the same height to adapt to the bottom shape of the side wall block 91.

[0055] The above-described scheme, which uses at least two side wall support beams 311 spaced apart, leaves a gap between adjacent side wall support beams 311 to facilitate observation and operation. Of course, in addition to the above scheme, support plates can also be used to replace the aforementioned side wall support beams 311.

[0056] For the side wall clamping mechanism 34, this embodiment provides a specific example: such as Figure 7 As shown, the sidewall clamping mechanism includes: at least one pair of clamping claws 341 and at least one clamping claw driver 342, wherein one clamping claw driver 342 is connected to one clamping claw 341 and is used to drive the clamping claw 341 to move.

[0057] Specifically, one pair, two pairs, or three pairs of grippers 341 can be used. When one pair of grippers 341 is used, the grippers 341 are located in the middle of the side wall block 91; when two or three pairs of grippers 341 are used, they are arranged at vertical intervals. This embodiment only uses one pair of grippers 341 as an example for explanation.

[0058] Two grippers 341 in a pair are arranged longitudinally at intervals, both of the same height, and there is space between them to accommodate the side wall block 91. The inner side of the gripper 341 is provided with a groove for the side of the side wall block 91 to be inserted.

[0059] One end of the gripper actuator 342 is connected to a gripper 341, and the other end is fixed to the frame 2. The gripper actuator 342 is used to drive the gripper 341 to swing, so that the two grippers 341 move closer or further apart. When the two grippers 341 move closer together, they grip the side wall blocks 91 from both sides; when the two grippers 341 move further apart, they release the side wall blocks 91. The gripper actuator 342 can be a drive mechanism such as a cylinder, hydraulic cylinder, or motor.

[0060] For the sidewall fine-tuning mechanism 33, this embodiment provides one implementation method: as follows Figure 7 As shown, the sidewall fine-tuning mechanism 33 includes a fine-tuning connector 331 and a fine-tuning actuator 332. One end of the fine-tuning actuator 332 is connected to the frame 2, and the other end is connected to the fine-tuning connector 331. The fine-tuning connector 331 is connected to the sidewall block 91. The fine-tuning actuator 332 drives the fine-tuning connector 331 to move laterally, acting on the lower part of the sidewall block 91, thereby achieving fine adjustment of the pitch angle of the sidewall block 91 to meet the needs of sidewall assembly.

[0061] The fine-tuning actuator 332 can be a pneumatic cylinder, a hydraulic cylinder, or other actuators. This embodiment uses a hydraulic cylinder as an example. The end of the fine-tuning connector 331 is fastened to the side wall block 91 by bolts. Two side wall fine-tuning mechanisms 33 are arranged at intervals. With the cooperation of the two side wall fine-tuning mechanisms 33, the side wall block 91 is finely adjusted forward and backward, and left and right, so that the H-beam at the bottom of the side wall block 91 aligns with the groove on the bottom plate. After alignment, the side wall block 91 is lowered and inserted into the groove.

[0062] Based on the above technical solution, the side wall mounting device 3 further includes a side wall mounting frame 35, which is disposed on one side of the frame 2. The side wall mounting frame 35 is a hollow structure, which is formed by connecting vertical beams, longitudinal beams and transverse beams to form a hollow frame structure.

[0063] The side wall fine-tuning mechanism 33 is located inside the side wall mounting bracket 35. The fine-tuning driver 332 in the side wall fine-tuning mechanism 33 can be fixed to the side wall mounting bracket 35 or to the frame 2. The side wall fine-tuning mechanism 33 extends laterally and can extend or retract from the inside of the side wall mounting bracket 35.

[0064] The side wall support mechanism 31 is located at the lower part of the side wall mounting bracket 35 and extends out of the side wall mounting bracket 35. One side surface of the side wall block 91 is attached to the side wall mounting bracket 35. The side wall clamping mechanism 34 is located above the side wall mounting bracket 35, and the gripper 341 extends out of the side wall mounting bracket 35 to clamp the side wall block 91.

[0065] Based on the above technical solutions, this embodiment provides an implementation method for the sidewall mounting mechanism 32: as follows Figure 8 As shown, the sidewall mounting mechanism includes: a sidewall longitudinal moving frame 321, a sidewall lifting frame 322, a sidewall transverse moving frame 323, a transverse moving arm 324, a longitudinal moving driver 325, a vertical moving driver 326, and a transverse moving driver 327.

[0066] The side wall longitudinal shifting frame 321 is mounted on the vehicle frame 2 and extends longitudinally. The side wall lifting frame 322 is slidably mounted on the side wall longitudinal shifting frame 321 and can move longitudinally relative to the side wall longitudinal shifting frame 321. The longitudinal drive 325 is mounted on the side wall longitudinal shifting frame and connected to the side wall lifting frame 322, providing longitudinal driving force to the side wall lifting frame 322.

[0067] The sidewall lateral movement frame 323 is slidably mounted on the sidewall lifting frame 322 and can move vertically relative to the sidewall lifting frame 322. The vertical drive 326 is mounted on the sidewall lifting frame 322 and connected to the sidewall lateral movement frame 323, providing vertical driving force to the sidewall lateral movement frame 323.

[0068] A transverse arm 324 is mounted on a side wall transverse frame 323 and can slide laterally relative to the side wall transverse frame 323. A transverse actuator 327 is mounted on the side wall transverse frame 323 and connected to the transverse arm 324, providing a transverse driving force to the transverse arm 324. The end of the transverse arm 324 is connected to the side wall block 91, and through the coordinated action of the above components, the side wall block 91 is moved longitudinally, laterally, and vertically.

[0069] The aforementioned side wall block 91 is placed on the side wall support mechanism 31, and the side wall clamping mechanism 34 clamps the side wall block 91. The trolley can move the side wall block 91 longitudinally for transport. After moving into position, the side wall clamping mechanism 34 releases the side wall block 91, and the side wall mounting mechanism 32 moves the side wall block 91 to the assembly position in the horizontal, longitudinal, and vertical directions for assembly. During this process, the position of the side wall block 91 can be finely adjusted by the side wall fine-tuning mechanism 33 so that the bottom end of the side wall block 91 is aligned with the assembly interface 20 (e.g., ...). Figure 12 ).

[0070] After the side wall block 91 is installed, an adjustment rod is installed on the top of the side wall block 91 to connect and fix it to the diaphragm wall. Concrete can then be poured between the side wall block 91 and the diaphragm wall.

[0071] Based on the above scheme, the side wall lifting frame 322 may specifically include a lifting top plate 3221 and lifting outriggers 3222 disposed at the bottom of the lifting top plate 3221. There are four lifting outriggers 3222, with two lifting outriggers forming a group. A gap is left between the two groups of lifting outriggers 3222 to accommodate the side wall longitudinal sliding frame 321. The two groups of lifting outriggers 3222 are arranged on both sides of the side wall longitudinal sliding frame 321. The gap between the lifting outriggers 3222 and the side wall longitudinal sliding frame 321 is only sufficient to allow for relative sliding between them. This scheme improves the stability of the side wall mounting mechanism 32 and prevents tipping.

[0072] The sidewall transverse sliding frame 323 may specifically include a lifting slide beam 3231 and a transverse sliding beam 3232. The lifting slide beam 3231 extends vertically and is retractably disposed within the internal space of a lifting outrigger 3222. The transverse sliding beam 3232 is connected to the top of each lifting slide beam 3231 and extends laterally. A transverse sliding arm 324 is retractably disposed within the internal space of the transverse sliding beam 3232.

[0073] For structures with steel walers or concrete waist beams on the side walls, the gantry crane cannot directly lift the side wall block 91 vertically onto the trolley due to the obstruction of the steel walers or concrete waist beams. To address this issue, this embodiment further optimizes the trolley, allowing the frame 2 to move laterally relative to the wheel-rail traveling device 1, thus supplementing the lateral travel of the side wall block 91.

[0074] Figure 13 The image shows two assembly trolleys assembling the side wall blocks on both sides of the platform. This embodiment uses the positions of these two trolleys to assemble the blocks in a case with a concrete lintel beam. Specifically, as shown... Figure 13 As shown, the frame 2 moves approximately 1.5m laterally away from the side wall, and the side wall block 91 is lifted downwards onto the trolley by a gantry crane (as shown). Figure 13 (The right-side trolley in the middle), during this process, the side wall block 91 can avoid the concrete waist beam 30. Specifically, the side wall block 91 is placed on the side wall support mechanism 31, and the side wall block 91 is held tightly by the side wall clamping mechanism 34. At this time, the height of the side wall block 91 is lower than the concrete waist beam 30, and the gantry crane is removed. Afterwards, the frame 2 moves laterally about 1.5m relative to the wheel-rail traveling device, close to the side wall (such as the right-side trolley). Figure 13 The right-hand trolley continues to move about 1 meter to the right, and then the side wall block 91 is assembled via the side wall installation mechanism 32, which solves the problem of the concrete waist beam obstructing the view. The left-hand trolley is in the assembled state of one side wall block.

[0075] If it is a steel waler, the frame can be moved 1m laterally so that the hoisting process of the side wall block 91 can avoid the steel waler.

[0076] Based on the above scheme, two trolleys can be used simultaneously to assemble the side walls on both sides of the bottom longitudinal beam 98. After the lower-level station is assembled, the trolley moves up to assemble the upper-level station.

[0077] Based on the above technical solution, for scenarios with steel temporary beams, this embodiment further optimizes the trolley, enabling the longitudinal beam installation device 4 to transport and assemble the middle longitudinal beam 95 and the top longitudinal beam 96. In this embodiment, the longitudinal beams mentioned below are all described using the middle longitudinal beam 95 as an example. Those skilled in the art can apply the solution of this embodiment to splicing the top longitudinal beam 96.

[0078] like Figures 14 to 16 As shown, the longitudinal beam mounting device 4 includes a moving platform 41 and a lifting frame 42. The moving platform 41 is located on the top of the vehicle frame 2 and can move laterally relative to the vehicle frame.

[0079] A lifting frame 42 is positioned above the mobile platform 41, with sufficient space between the lifting frame 42 and the mobile platform 41 to accommodate the longitudinal beam. At least two connecting parts are provided on the outer end of the lifting frame 42 for temporarily connecting the longitudinal beam. At the open-air opening, the gantry crane lifts the longitudinal beam (e.g., the middle longitudinal beam 95) and moves it to the area between the mobile platform 41 and the lifting frame 42. Then, the connecting parts on the lifting frame 42 are connected to the middle longitudinal beam 95, and the gantry crane is removed after the connection is complete. The trolley can transport the middle longitudinal beam 95 by traveling along the track using a wheel-rail traveling device.

[0080] When moving to the target position, the moving platform 41 extends laterally toward the longitudinal beam 95 to be assembled. After reaching the accurate position, the longitudinal beam 95 is lowered and overlapped between two adjacent central columns 92. The connection between the connecting part of the hoisting frame 42 and the longitudinal beam 95 is disassembled to complete the assembly of the longitudinal beam 95.

[0081] The technical solution provided in this embodiment includes a trolley equipped with a wheel-rail traveling device, a frame, and a longitudinal beam installation device. The wheel-rail traveling device is located at the bottom of the frame and can travel along the track on the platform floor. The longitudinal beam installation device is located on the frame and is used to fix the longitudinal beam and move it to the target position for assembly. The longitudinal beam installation device includes: a moving platform located on the top of the frame and capable of moving laterally relative to the frame; a lifting frame located above the moving platform, with space between the lifting frame and the moving platform to accommodate the longitudinal beam; the outer end of the lifting frame is provided with at least two connecting parts for temporarily connecting the longitudinal beam, enabling the assembly of the station's longitudinal beams in application scenarios where a gantry crane cannot be used, and has high operational efficiency.

[0082] Based on the above technical solution, the longitudinal beam installation device 4 further includes a longitudinal beam support frame 43. The longitudinal beam support frame 43 is disposed above the mobile platform 41 and extends vertically, with a space for accommodating the longitudinal beam left between the top of the longitudinal beam support frame 43 and the connecting part on the hoisting frame 42.

[0083] Considering the long travel distance of the trolley, in order to reduce the risks during the hoisting process, the longitudinal beam can be placed on the longitudinal beam support frame 43, and the longitudinal beam can be supported by the longitudinal beam support frame 43.

[0084] The longitudinal beam support frame 43 can be formed by multiple rod-shaped mechanisms arranged and connected to each other along the vertical, transverse and longitudinal beams respectively, which can support the weight of the longitudinal beam and ensure the stability of the longitudinal beam during the movement of the trolley.

[0085] Furthermore, the lifting frame 42 can move laterally relative to the moving platform 41. When the lateral movement of the moving platform 41 is limited, the lifting frame 42 can be further moved laterally to increase the lateral movement of the longitudinal beam, thereby meeting the assembly requirements of the longitudinal beam.

[0086] The lifting frame 42 can also move vertically relative to the moving platform 41 to accommodate longitudinal beams of different thicknesses. For example, the vertical support column 44 is vertically mounted on the moving platform 41 or on the vehicle frame 2, and the lifting frame 42 is mounted at the top of the vertical support column 44. The lifting frame 42 can move up and down relative to the vertical support column 44.

[0087] For the lifting frame 42, this embodiment provides an implementation method: the lifting frame 42 includes a lifting arm 421 and two auxiliary arms 422. The two auxiliary arms 422 are parallel and side-by-side, extending laterally and spaced apart longitudinally. The lifting arm 421 is connected between the outer ends of the two auxiliary arms 422, and a connecting portion 423 for connecting the longitudinal beam is provided on the lifting arm 421. Specifically, the lifting arm 421 and the two auxiliary arms 422 are connected to form a rectangular frame with one open end, the open end being away from the position where the longitudinal beam to be assembled is to be placed. The lifting arm 421 is close to the position where the longitudinal beam to be assembled is to be placed.

[0088] Based on the above scheme, a sliding guide structure is provided between the top of the auxiliary arm 422 and the top of the moving platform 41, allowing the auxiliary arm 422 to move laterally relative to the moving platform 41 via the sliding guide structure. The sliding guide structure can be located at the top of the vertical support column 44 and can be a slider and a slide rail, or a slider and a slide groove. A hydraulic cylinder or other driving mechanism is used to provide lateral driving force to the auxiliary arm 422.

[0089] The connecting part 423 on the lifting frame 42 can be a lifting ring, with at least two lifting rings spaced apart along the length direction (i.e., longitudinal direction) of the lifting arm 421, sufficient to meet the lifting requirements of the longitudinal beam. The lifting rings can be connected to the longitudinal beam via ropes.

[0090] Alternatively, the connecting part 423 can also be a hook, which is hooked onto the lifting ring at the top of the longitudinal beam.

[0091] The above technical solution enables the hoisting of longitudinal beams. During construction, a trolley is used to first assemble the central columns 92 in the middle of the station, with multiple central columns 92 arranged longitudinally at intervals. Then, the trolley carries the longitudinal beams 95 to the position between two adjacent central columns 92. The longitudinal beams 95 are then lifted using a hoisting frame 42, moved laterally between and above the two central columns 92, and lowered after positioning, overlapping between the two adjacent central columns 92. A longitudinal clamping force is then applied to the central columns 92 to longitudinally tighten the longitudinal beams 95, completing the longitudinal beam assembly.

[0092] In the above scheme, all the central columns can be installed before assembling the central longitudinal beams; alternatively, one central longitudinal beam can be assembled after each pair of adjacent central columns are completed.

[0093] Based on the above technical solution, the longitudinal beam installation device 4 can also be used to hoist, transport, and install the central column 92. Specifically, a lifting ring or other structure can be installed on the top of the central column 92 and connected to the connecting part on the hoisting frame 42 to realize the hoisting of the central column 92.

[0094] Furthermore, the mobile platform 41 is optimized to enable it to support and fix the central column 92. For example... Figure 9 As shown, the mobile platform 41 includes two mobile platforms 411, which are arranged parallel to each other and extend laterally. A space is left between the two mobile platforms 411 to accommodate the central column 92. The central column 92 is placed between the two mobile platforms 411, and the mobile platforms 411 are used for temporary fixation and transport of the central column 92.

[0095] One specific implementation is as follows: the cross-section of the middle section of the central column 92 and the cross-section of the top section of the central column 92 are both rectangular, and the length of the cross-section of the middle section of the central column 92 is less than the length of the cross-section of the top section. The distance between the two movable platforms 411 is less than the length of the cross-section of the top section of the central column 92, but greater than the length of the cross-section of the middle section of the central column 92. Thus, the middle section of the central column 92 enters through the gap between the two movable platforms 411 and is secured between them, preventing it from falling downwards. Therefore, the two movable platforms 411 effectively fix and support the central column 92.

[0096] Furthermore, a locking element 412 is provided at the outer end of the movable platform 411. A locking rod 413 with a length greater than the distance between the two movable platforms is used, and both ends of the locking rod 413 are detachably connected to the locking elements 412 on the two movable platforms 411 respectively. The locking rod 413 is used to prevent the central column 92 from moving outward, further improving the reliability during the transport process and preventing the central column 92 from coming out of the gap between the two movable platforms 411 and falling down.

[0097] Additionally, a central column support surface can be provided on the upper surface of the end corresponding to the longitudinal beam mounting device 4 in the wheel-rail traveling device 1, with the bottom end of the central column 92 abutting against the central column support surface. The central column support surface can be concave to position the central column 92 and improve its stability.

[0098] Based on the above technical solutions, such as Figures 17 to 21 As shown, this embodiment also provides an implementation of the top plate installation device 5, including a top plate lifting frame 51, a top plate support frame 52, and a top plate lifting drive mechanism 53.

[0099] Among them, the top plate lifting frame 51 is set at the top of the vehicle frame 2. It can be made of multiple strip beams arranged and connected in the horizontal, longitudinal and vertical directions to form a hollow frame structure, and can be welded to the top of the vehicle frame 2.

[0100] The top plate support frame 52 is disposed at the top of the top plate lifting frame 51 and can move vertically relative to the top plate lifting frame 51. The top plate support frame 52 is used to support the top plate. The top plate mentioned below is taken as the middle top plate 93 as an example. Those skilled in the art can apply the technical solution provided in this embodiment to the assembly of the top plate 94.

[0101] The roof lifting drive mechanism 53 is located between the roof lifting frame 51 and the roof support frame 52, and is used to provide the driving force for vertical movement of the roof.

[0102] During construction, at the open-air opening at one end of the steel temporary beam, the central roof slab 93 is lifted by a gantry crane onto the roof slab support frame 52, which supports the central roof slab 93. Then, the trolley travels along the track to the installation position, and the height of the roof slab support frame 52 is adjusted by the roof slab lifting drive mechanism 53, so that the central roof slab 93 above the roof slab support frame 52 is higher than the side wall blocks 91 and the central longitudinal beam 95. The trolley then continues to travel towards the installed central roof slab 93 until it reaches the target position. The roof slab lifting drive mechanism 53 then lowers the roof slab support frame 52 and the central roof slab 93 until both ends of the central roof slab 93 overlap the side wall blocks 91 and the central longitudinal beam 95, completing the assembly of the central roof slab 93.

[0103] Based on the above technical solution, this embodiment provides an implementation method for a roof support frame 52: the roof support frame 52 includes two roof support beams 521, which are parallel and side-by-side, respectively located on both sides of the roof lifting frame 51. The distance between the two roof support beams 521 is less than the length of the roof. The roof is placed on the two roof support beams 521 in a direction perpendicular to the length of the roof and the roof support beams 521.

[0104] Furthermore, the roof lifting frame 51 can also move laterally relative to the frame 2. During the assembly process, the lateral movement of the roof lifting frame 51 can adjust the lateral position of the middle roof 93.

[0105] Furthermore, an extrusion fixture 54 is also installed on the upper surface of the middle part of the top plate support beam 521, and the extrusion fixture 54 can move relative to the top plate support beam 521. An extrusion drive is installed on the top plate support beam 521 and connected to the extrusion fixture 54 to apply longitudinal driving force to the extrusion fixture 54. During the transport process, the middle top plate 93 is placed on the extrusion fixture 54. During the assembly process, after the middle top plate 93 is overlapped on the side wall block 91 and the central longitudinal beam 95, the extrusion drive can be activated to drive the extrusion fixture 54 to apply longitudinal extrusion force to the middle top plate 93, so as to press the newly assembled middle top plate 93 tightly.

[0106] A sealing strip is embedded on the side of the top plate 93. When longitudinal pressure is applied to the top plate 93, the sealing strip is pressed tightly between adjacent top plates 93 to improve the waterproof effect.

[0107] 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.
