[0023] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the exemplary embodiments of the present application are further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0024] The embodiment provides a superimposed station construction system, which is suitable for assembling a superimposed subway station, can improve construction efficiency, and shorten the construction period. The system can assemble a single-layer station, a double-layer station, and also can assemble a three-layer station or a four-layer station.

[0025] The superimposed subway station comprises a side wall block, a middle column, a longitudinal beam and a top plate. The side wall block and the middle column are distributed on both sides of the station along the vertical direction, the longitudinal beam is located between two adjacent middle columns, and the top plate is located between the side wall block and the longitudinal beam.

[0026] For a station with more than two layers, the top plate is divided into a middle top plate located in the lower layer and a top plate located in the upper layer; and the longitudinal beam is divided into a middle longitudinal beam located in the lower layer and a top longitudinal beam located in the upper layer.

[0027] Figure 1 It is shown that the double-layer station, the superimposed subway station comprises a side wall block 91, a middle column 92, a middle top plate 93, a top plate 94, a middle longitudinal beam 95, a top longitudinal beam 96 and a bottom plate 97. In the construction process, the bottom plate 97 of the platform and the bottom longitudinal beam 98 located in the middle of the bottom plate 97 are first poured to form. The longitudinal direction is the length direction of the platform and also the driving direction. Along the longitudinal direction, a plurality of side wall blocks 91 are sequentially spliced to form a side wall, a plurality of middle columns 92 are arranged at intervals, and a plurality of middle longitudinal beams 95 are sequentially spliced and the middle longitudinal beams 95 are overlapped on the adjacent two middle columns 92. The middle top plate 93 is overlapped between the side wall block 91 and the middle longitudinal beam 95 along the transverse direction, and a plurality of middle top plates 93 are sequentially spliced along the longitudinal direction. The above-mentioned side wall block 91, middle column 92, middle longitudinal beam 95 and middle top plate 93 constitute the lower layer structure of the station. After the lower layer structure construction is completed, the upper layer structure of the station is started to be built.

[0028] In the upper structure of the station, upper intermediate columns 92 are arranged along the longitudinal direction above the intermediate beams 95, and then top longitudinal beams 96 are arranged between the adjacent upper intermediate columns 92. The upper side wall blocks 91 are arranged in sequence on the top of the lower side wall blocks 91, and the top plates 94 are arranged between the upper side wall blocks 91 and the top longitudinal beams 96, and the top plates 94 are sequentially spliced along the longitudinal direction.

[0029] Figure 2 It is shown that the station is three-layer. Similar to the double-layer 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 the double-layer station, and the middle structure and the top structure are respectively referred to the upper structure in the double-layer station.

[0030] As shown in Figure 3 The assembling trolley 10 is used to construct the lower structure, and after the construction is completed or meets certain conditions, the assembling trolley 10 is used to construct the upper structure.

[0031] The construction system includes a first assembling trolley, a second assembling trolley and a gantry crane. In the early stage of construction, the construction pit is formed by open excavation, and the gantry crane is installed in the pit to hoist and transport the components in the construction process.

[0032] In the above, the bottom longitudinal beams 98 divide the bottom plates 97 of the platform into two platform areas (referred to as station areas), and the tracks extending along the longitudinal direction are arranged on the bottom plates 97 in each station area. The first assembling trolley and the second assembling trolley are used to install in the two station areas and can walk along the tracks. The first assembling trolley and the second assembling trolley are respectively used to assemble the side wall blocks, the intermediate columns, the longitudinal beams and the top plates in the two station areas. The two assembling trolleys can independently assemble or cooperate with each other.

[0033] The first assembling trolley and the second assembling trolley can have the same structure or slightly different structures according to needs.

[0034] The first assembling trolley includes a frame, a wheel track walking device, a side wall mounting device and an operation platform. The wheel track walking device is located at the bottom of the first assembling trolley and is arranged on the track in the area of one side of the bottom plate of the station (i.e. one station area) to walk along the track in the longitudinal direction. The side wall mounting device is used to carry the side wall blocks and sequentially splice the side wall blocks to form the side wall on one side of the station. In the construction process, the construction personnel can stand on the operation platform to assist in observation and cooperation.

[0035] The second assembling trolley comprises a trolley frame, a wheel-rail running device, a side wall mounting device and an operation platform. The wheel-rail running device is arranged at the bottom of the second assembling trolley and is arranged on the track in the other area of the station bottom plate, and can run longitudinally along the track. The side wall mounting device is used for carrying the side wall blocks and sequentially assembling the side wall blocks to the other side of the station to form a side wall. During the construction process, the construction personnel can stand on the operation platform to perform auxiliary observation and cooperation operation.

[0036] The gantry crane is used for hoisting the side wall blocks to the first assembling trolley or the second assembling trolley, and specifically to the side wall mounting device.

[0037] The technical scheme provided in the embodiment comprises the following steps: the first assembling trolley, the second assembling trolley and the gantry crane are used to assemble the side wall blocks of the station; the gantry crane is used for hoisting the side wall blocks to the first assembling trolley or the second assembling trolley; the first assembling trolley comprises a trolley frame, a wheel-rail running device, a side wall mounting device and an operation platform; the wheel-rail running device is arranged at the bottom of the first assembling trolley and is arranged on the track in the area of one side of the station bottom plate, and can run longitudinally along the track; the side wall mounting device is used for carrying the side wall blocks and sequentially assembling the side wall blocks to one side of the station to form a side wall; the second assembling trolley comprises a trolley frame, a wheel-rail running device, a side wall mounting device and an operation platform; the wheel-rail running device is arranged at the bottom of the second assembling trolley and is arranged on the track in the area of the other side of the station bottom plate, and can run longitudinally along the track; the side wall mounting device is used for carrying the side wall blocks and sequentially assembling the side wall blocks to the other side of the station to form a side wall; the above scheme realizes the assembly of the side wall of the superimposed station, and the first assembling trolley and the second assembling trolley are used to assemble the two station areas respectively, and work in parallel, so that the construction efficiency can be doubled.

[0038] The above scheme can be applied to the scene that there is no steel temporary beam on the top of the construction area, and the gantry crane can hoist the parts in the whole construction area.

[0039] On the basis of the above technical scheme, the gantry crane is also used for sequentially hoisting the middle columns to the target positions in the middle of the station, and the first assembling trolley or the second assembling trolley correspondingly runs to the target positions and adjusts the position of the operation platform to cooperate with the gantry crane to install the middle columns in the middle of the station bottom plate, and the middle columns are arranged in the longitudinal direction.

[0040] Further, the gantry crane is also used for sequentially hoisting the longitudinal beams to the target positions in the middle of the station, and the first assembling trolley or the second assembling trolley correspondingly runs to the target positions and adjusts the position of the operation platform to cooperate with the gantry crane to install the longitudinal beams between the adjacent two middle columns; the longitudinal beams extend in the longitudinal direction, and the longitudinal beams are sequentially arranged in the longitudinal direction.

[0041] Further, the gantry crane is also used to hoist the top plates to the target positions between the center column and the side wall one by one, and the first assembling trolley or the second assembling trolley is correspondingly moved to the target positions and the position of the operation platform is adjusted to cooperate with the gantry crane to overlap the top plates between the longitudinal beams and the side wall; the top plates are arranged in sequence along the longitudinal direction.

[0042] In the process of hoisting and assembling the center column, the longitudinal beam and the top plate, the construction personnel can observe and cooperate on the operation platform.

[0043] In the above scheme, the assembling trolley is only used for assembling the side wall blocks, and the structure design meets the requirements of carrying and assembling the side wall blocks, so the structure is relatively simple, and the installation and disassembly process is relatively simple and fast.

[0044] On the basis of the above technical scheme, in the embodiment, the first assembling trolley and the second assembling trolley can adopt the same structure, and the frame, the wheel rail running device, the side wall mounting device and the operation platform adopt the same structure. The embodiment also gives a specific implementation manner: As shown in Figures 4 to 11 The assembling trolley comprises a wheel rail running device 1, a frame 2 and a side wall mounting device 3. After the bottom plate 97 of the station is formed, temporary tracks are laid on both sides of the bottom longitudinal beam 98 on the bottom plate 97, and the tracks extend along the longitudinal direction. The wheel rail running device 1 can run along the tracks on the bottom plate 97, so that the trolley can move longitudinally to gradually assemble. The frame 2 is arranged above the wheel rail running device 1 and serves as the main frame structure of the trolley, and all components of the trolley are mounted on the frame 2.

[0045] The side wall mounting device 3 is arranged on the frame 2. The side wall block 91 is hoisted to the side wall mounting device 3 by the gantry crane, and the side wall mounting device 3 fixes and moves the side wall block 91 to the side wall mounting position for assembly. In the embodiment, the side wall of the station comprises a plurality of side wall blocks 91, which are arranged in sequence along the longitudinal direction to form the side wall of the station. During construction, the trolley runs longitudinally to assemble the side wall blocks 91 in sequence.

[0046] As shown in Figure 5 The side wall mounting device 3 comprises a side wall supporting mechanism 31, a side wall mounting mechanism 32 and a side wall fine adjustment mechanism 33. The side wall supporting mechanism 31 is arranged at the lower part of the frame 2 and extends to one side of the frame 2, specifically towards the direction of the side wall to be assembled. The side wall block 91 is hoisted to the side wall supporting mechanism 31 by the gantry crane, and the side wall supporting mechanism 31 is used to support the side wall block 91 from the bottom.

[0047] The side wall mounting mechanism 32 is arranged on the top of the frame 2. When the gantry crane hoists the side wall block 91 to the side wall supporting mechanism 31, the side wall mounting mechanism 32 is connected with the side wall block 91, and 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 to realize assembly.

[0048] The side wall fine adjustment mechanism 33 is arranged on the lower part of the frame 2, and is used to apply a force to the lower part of the side wall block 91 to finely adjust the pitch angle of the side wall block 91.

[0049] In the above scheme, the side wall supporting mechanism is arranged on the lower part of the frame, extends to one side of the frame from the bottom, and is used to support the side wall block from the bottom; the side wall mounting mechanism is arranged on the top of the frame, and is used to apply a pushing force to the side wall block to move the side wall block to realize assembly; and the side wall fine adjustment mechanism is arranged on the lower part of the frame, and is used to apply a force to the lower part of the side wall block to finely adjust the pitch angle of the side wall block, so as to realize assembly of the side wall of the station and solve the problems of low efficiency and poor quality in cast-in-place.

[0050] In addition, in the above scheme, the side wall block is supported by the side wall supporting mechanism, the side wall mounting mechanism applies a pushing force to the side wall block to move the side wall block to realize assembly, and the side wall fine adjustment mechanism is used to finely adjust the pitch angle of the side wall block, so as to ensure stable installation of the side wall block and improve accuracy, thereby improving assembly quality.

[0051] On the basis of the above technical scheme, the side wall mounting device 3 further includes a side wall clamping mechanism 34. The side wall clamping mechanism 34 is arranged on the middle part of the frame 2, extends to the side of the side wall block 91 away from the trolley from both sides of the side wall block 91, and applies a clamping force to the side wall block 91 to avoid tilting of the side wall block 91 during movement.

[0052] The embodiment provides an implementation manner: 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 hoisted to the side wall mounting device 3 by the gantry crane, and is moved to the position by the side wall mounting mechanism 32 along the horizontal direction, the longitudinal direction and the vertical direction to realize assembly.

[0053] For the side wall supporting mechanism 31, the embodiment provides a specific example: as shown in Figure 7 The side wall supporting mechanism 31 includes at least two side wall supporting beams 311, and the side wall supporting beams 311 extend along the horizontal direction. The at least two side wall supporting beams 311 are arranged at intervals along the longitudinal direction. The side wall block 91 is placed on each side wall supporting beam 311, and each side wall supporting beam 311 supports the side wall block 91.

[0054] The side wall supporting beam 311 can be a steel beam with a cross section in the shape of a mouth, can be an I-shaped steel beam, or can be a steel beam with other shapes.

[0055] Further, the upper surface of the side wall supporting beam 311 is flat, and the upper surfaces of the side wall supporting beams 311 are at the same height to adapt to the shape of the bottom surface of the side wall block 91.

[0056] The above-mentioned scheme of spacing the side wall supporting beams 311 at intervals of at least two side wall supporting beams 311 leaves a gap between adjacent two side wall supporting beams 311, facilitating observation and operation. Of course, in addition to the above-mentioned scheme, a supporting plate can also be used instead of the above-mentioned side wall supporting beams 311.

[0057] For the side wall clamping mechanism 34, the embodiment provides a specific example: the side wall clamping mechanism comprises at least one pair of clamping claws 341 and at least one clamping claw driver 342, one clamping claw driver 342 corresponding to one clamping claw 341 is connected to drive the clamping claw 341 to act.

[0058] Specifically, one pair of clamping claws 341, two pairs of clamping claws 341 or three pairs of clamping claws 341 can be used, when one pair of clamping claws 341 is used, the clamping claws 341 are located in the middle of the side wall block 91; when two pairs of clamping claws 341 or three pairs of clamping claws 341 are used, they are arranged at intervals along the vertical direction. The embodiment is only described by taking one pair of clamping claws 341 as an example.

[0059] The two clamping claws 341 in a pair are arranged at intervals along the longitudinal direction, and have the same height and leave a space for accommodating the side wall block 91. The inner side of the clamping claw 341 is provided with a groove for embedding the side surface of the side wall block 91.

[0060] One end of the clamping claw driver 342 is connected to one clamping claw 341, and the other end is fixed to the vehicle frame 2. The clamping claw driver 342 is used to drive the clamping claw 341 to swing, so that the two clamping claws 341 move close to or away from each other. When the two clamping claws 341 move close to each other, the side wall block 91 is clamped from both sides; when the two clamping claws 341 move away from each other, the side wall block 91 is released. The clamping claw driver 342 can be a driving mechanism such as a pneumatic cylinder, a hydraulic cylinder or a motor.

[0061] For the side wall fine adjustment mechanism 33, the embodiment provides an implementation: the side wall fine adjustment mechanism 33 comprises a fine adjustment connecting head 331 and a fine adjustment driver 332. One end of the fine adjustment driver 332 is connected to the vehicle frame 2, and the other end is connected to the fine adjustment connecting head 331. The fine adjustment connecting head 331 is connected to the side wall block 91. The fine adjustment driver 332 is used to drive the fine adjustment connecting head 331 to move along the transverse direction, and acts on the lower part of the side wall block 91, so as to finely adjust the pitch angle of the side wall block 91 to meet the needs of side wall assembly.

[0062] The fine adjustment driver 332 can be a pneumatic cylinder, a hydraulic cylinder or other driver. In this embodiment, the hydraulic cylinder is taken as an example, and the end of the fine adjustment connector 331 is connected and fastened to the side wall block 91 by bolts. Two side wall fine adjustment mechanisms 33 are arranged at intervals, and the side wall block 91 is fine adjusted in front and back and left and right under the cooperation of the two side wall fine adjustment mechanisms 33, so that the H-shaped steel at the bottom end of the side wall block 91 is aligned with the groove on the bottom plate block, and the side wall block 91 is then inserted into the groove after alignment.

[0063] On the basis of the above technical solutions, the side wall mounting device 3 further comprises a side wall mounting frame 35 arranged on one side of the vehicle frame 2. The side wall mounting frame 35 is a hollow structure, and is connected by vertical beams, longitudinal beams and transverse beams into a hollow frame structure.

[0064] The side wall fine adjustment mechanism 33 is located in the internal space of the side wall mounting frame 35, and the fine adjustment driver 332 in the side wall fine adjustment mechanism 33 can be fixed to the side wall mounting frame 35 or the vehicle frame 2. The side wall fine adjustment mechanism 33 extends in the transverse direction and can extend out of or retract into the internal space of the side wall mounting frame 35.

[0065] The side wall supporting mechanism 31 is located at the lower part of the side wall mounting frame 35 and extends out of the side wall mounting frame 35. One side surface of the side wall block 91 is attached to the side wall mounting frame 35. The side wall clamping mechanism 34 is located above the side wall mounting frame 35, and the clamping claws 341 extend out of the side wall mounting frame 35 to clamp the side wall block 91.

[0066] On the basis of the above technical solutions, this embodiment provides an implementation of the side wall mounting mechanism 32: as shown in Figure 8 the side wall mounting mechanism comprises a side wall longitudinal moving frame 321, a side wall lifting frame 322, a side wall transverse moving frame 323, a transverse moving arm 324, a longitudinal moving driver 325, a vertical driving driver 326 and a transverse moving driver 327.

[0067] The side wall longitudinal moving frame 321 is arranged on the vehicle frame 2 and extends in the longitudinal direction. The side wall lifting frame 322 is slidingly arranged on the side wall longitudinal moving frame 321 and can move relative to the side wall longitudinal moving frame 321 in the longitudinal direction. The longitudinal moving driver 325 is arranged on the side wall longitudinal moving frame and connected to the side wall lifting frame 322 to provide a longitudinal moving driving force to the side wall lifting frame 322.

[0068] The side wall transverse moving frame 323 is slidingly arranged on the side wall lifting frame 322 and can move relative to the side wall lifting frame 322 in the vertical direction. The vertical driving driver 326 is arranged on the side wall lifting frame 322 and connected to the side wall transverse moving frame 323 to provide a vertical driving force to the side wall transverse moving frame 323.

[0069] The transverse moving arm 324 is arranged on the side wall transverse moving frame 323 and can slide relative to the side wall transverse moving frame 323 in the transverse direction. The transverse moving driver 327 is arranged on the side wall transverse moving frame 323 and connected with the transverse moving arm 324 to provide a transverse driving force for the transverse moving arm 324. The end of the transverse moving arm 324 is connected with the side wall block 91, and through the cooperation of the above components, the side wall block 91 can be moved in the longitudinal direction, the transverse direction and the vertical direction.

[0070] The side wall block 91 is placed on the side wall supporting mechanism 31, the side wall block 91 is clamped by the side wall clamping mechanism 34, and the trolley can drive the side wall block 91 to move in the longitudinal direction to realize the carrying operation. After moving to the position, the side wall block 91 is released by the side wall clamping mechanism 34, and the side wall block 91 is driven by the side wall mounting mechanism 32 to move in the transverse direction, the longitudinal direction and the vertical direction to the assembling position for assembling. In this process, the position of the side wall block 91 can be finely adjusted by the side wall fine adjustment mechanism 33, so that the bottom end of the side wall block 91 is aligned with the assembling interface 20 (for example Figure 12 ).

[0071] After the side wall block 91 is installed, the adjusting pull rod connected with the diaphragm wall is installed on the top of the side wall block 91 to connect and fix with the diaphragm wall. Subsequently, concrete can be poured between the side wall block 91 and the diaphragm wall.

[0072] Based on the above scheme, the side wall lifting frame 322 can specifically include a lifting top plate 3221 and lifting legs 3222 arranged at the bottom of the lifting top plate 3221. The number of the lifting legs 3222 is four, wherein two lifting legs 3222 form a group, and the two groups of lifting legs 3222 leave a gap that can accommodate the side wall longitudinal moving frame 321, and the two groups of lifting legs 3222 are arranged on both sides of the side wall longitudinal moving frame 321. The gap between the lifting legs 3222 and the side wall longitudinal moving frame 321 can only satisfy the relative sliding of the two. The above scheme can improve the stability of the side wall mounting mechanism 32 and avoid tilting.

[0073] For the side wall transverse moving frame 323, it specifically can include lifting sliding beams 3231 and a transverse moving beam 3232. The lifting sliding beams 3231 extend in the vertical direction, and one lifting sliding beam 3231 is telescopically arranged in the inner space of one lifting leg 3222. The transverse moving beam 3232 is connected to the top of each lifting sliding beam 3231, and the transverse moving beam 3232 extends in the transverse direction. The transverse moving arm 324 is telescopically arranged in the inner space of the transverse moving beam 3232.

[0074] For the structure that the side wall is provided with a steel enclosing purlin or a concrete waist beam, the gantry crane cannot directly hoist the side wall block 91 vertically downward to the trolley due to the obstruction of the steel enclosing purlin or the concrete waist beam. To solve this problem, the trolley is further optimized in this embodiment. The vehicle frame 2 can move relative to the wheel rail running device 1 in the transverse direction, which can compensate for the transverse travel of the side wall block 91.

[0075] Figure 13 Two assembling trolleys are shown to assemble the side wall blocks on both sides of the platform. In this embodiment, the two trolleys are used to assemble the side wall blocks with the concrete waist beam. Specifically, as shown in Figure 13 , the trolley frame 2 is moved about 1.5m away from the side wall in the transverse direction, and the side wall block 91 is hoisted down by the gantry crane to the trolley (e.g. the right trolley in Figure 13 ). 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 supporting mechanism 31, and the side wall block 91 is clamped 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. Then the trolley frame 2 is moved about 1.5m in the transverse direction relative to the wheel rail running device, and approaches the side wall (e.g. the right trolley in Figure 13 continues to move about 1m to the right, and then the side wall block 91 is assembled by the side wall mounting mechanism 32, which can solve the problem of obstruction by the concrete waist beam. The left trolley is in the state of completing the assembly of a side wall block.

[0076] If it is a steel surrounding purlin, the trolley frame is moved 1m in the transverse direction, so that the hoisting process of the side wall block 91 can avoid the steel surrounding purlin.

[0077] Based on the above scheme, two trolleys can be used to assemble the side walls on both sides of the bottom longitudinal beam 98 simultaneously. After the assembly at the lower station is completed, the trolleys are moved upward to assemble the upper station.

[0078] The above operation platform can be located at the top of the trolley frame 2, and the operation platform includes an operation base plate and a fence surrounding the operation base plate. One side of the fence is provided with an access door. The trolley frame 2 is provided with a ladder, and the top end of the ladder corresponds to the position of the access door. Construction personnel can climb up from the ladder and enter the operation platform through the access door to observe and cooperate. The access door needs to be closed and locked during the construction process.

[0079] The bottom of the operation platform is provided with a lifting fork arm, which can be driven by a hydraulic mechanism to actuate the lifting fork arm to lift the operation platform, thereby cooperating with the construction process.

[0080] On the basis of the above technical scheme, the trolley is further optimized in this embodiment, so that the trolley can also carry and assemble longitudinal beams. Specifically, the longitudinal beam mounting device 4 can carry and assemble the middle longitudinal beam 95 and the top longitudinal beam 96. In this embodiment, the longitudinal beams appearing below are taken as examples of the middle longitudinal beam 95, and those skilled in the art can apply the scheme of this embodiment to the assembly of the top longitudinal beam 96.

[0081] As shown in Figures 14 to 16 , the longitudinal beam mounting device 4 includes a moving platform 41 and a hoisting frame 42. The moving platform 41 is arranged at the top of the trolley frame 2 and can move transversely relative to the trolley frame.

[0082] The hoisting frame 42 is arranged above the moving platform 41, and a space for accommodating the longitudinal beam is left between the hoisting frame 42 and the moving platform 41. The outer side end of the hoisting frame 42 is provided with at least two connecting portions for temporarily connecting the longitudinal beam. At the open-air opening, the gantry crane hoists the longitudinal beam (for example, the middle longitudinal beam 95) and moves it to the area between the moving platform 41 and the hoisting frame 42, and then connects the connecting portions on the hoisting frame 42 with the middle longitudinal beam 95, and after the connection is completed, the gantry crane is withdrawn. The trolley can walk along the rail track walking device to carry the middle longitudinal beam 95.

[0083] When moving to the target position, the moving platform 41 extends in the transverse direction towards the direction of assembling the middle longitudinal beam 95, and after reaching the accurate position, the middle longitudinal beam 95 is lowered and overlapped between the two adjacent middle upright columns 92, the connection between the connecting portions in the hoisting frame 42 and the middle longitudinal beam 95 is disassembled, and the assembly of the middle longitudinal beam 95 is completed.

[0084] The technical scheme provided by the embodiment is that the trolley is provided with a rail track walking device, a frame and a longitudinal beam mounting device; the rail track walking device is arranged at the bottom of the frame and can walk along the track on the platform bottom plate; the longitudinal beam mounting device is arranged on the frame and is used for fixing the longitudinal beam and moving the longitudinal beam to the target position for assembly; the longitudinal beam mounting device comprises a moving platform arranged at the top of the frame and capable of moving the frame in the transverse direction; and a hoisting frame arranged above the moving platform and leaving a space for accommodating the longitudinal beam between the hoisting frame and the moving platform; the outer side end of the hoisting frame is provided with at least two connecting portions for temporarily connecting the longitudinal beam, which can realize the assembly of the longitudinal beam of the station in the application scene where the gantry crane cannot be applied, and has high work efficiency.

[0085] On the basis of the above technical scheme, the longitudinal beam mounting device 4 further comprises a longitudinal beam support frame 43. The longitudinal beam support frame 43 is arranged above the moving platform 41 and extends in the vertical direction, and a space for accommodating the longitudinal beam is left between the top of the longitudinal beam support frame 43 and the connecting portions on the hoisting frame 42.

[0086] Considering that the distance walked by the trolley is long, in order to reduce the risk existing in the hoisting and walking process, the longitudinal beam can be placed on the longitudinal beam support frame 43, and the longitudinal beam is supported by the longitudinal beam support frame 43.

[0087] The longitudinal beam support frame 43 can adopt a plurality of rod-shaped mechanisms arranged along the vertical direction, the transverse direction and the longitudinal direction and connected with each other, which can support the weight of the longitudinal beam and ensure the stability of the longitudinal beam during the walking process of the trolley.

[0088] Further, the hoisting frame 42 can move in the transverse direction relative to the moving platform 41. When the stroke of the moving platform 41 moving in the transverse direction is limited, the hoisting frame 42 can be further moved in the transverse direction to increase the stroke of the longitudinal beam, thereby meeting the assembly needs of the longitudinal beam.

[0089] The lifting frame 42 can also move vertically relative to the moving platform 41 to meet the needs of longitudinal beams of different thicknesses. For example, a vertical support 44 is arranged vertically on the moving platform 41 or on the vehicle frame 2, and the lifting frame 42 is arranged at the top end of the vertical support 44. The lifting frame 42 can move up and down relative to the vertical support 44.

[0090] For the lifting frame 42, the embodiment provides an implementation: the lifting frame 42 includes a lifting arm 421 and two auxiliary arms 422 arranged in parallel and side by side, the auxiliary arms 422 extend in the transverse direction, and the two auxiliary arms 422 are arranged in the longitudinal direction. The lifting arm 421 is connected between the outer ends of the two auxiliary arms 422, and the lifting arm 421 is provided with a connecting portion 423 for connecting the longitudinal beam. Specifically, the lifting arm 421 and the two auxiliary arms 422 are connected into an open rectangular frame, and the open end is away from the position where the longitudinal beam is to be assembled. The lifting arm 421 is close to the position where the longitudinal beam is to be assembled.

[0091] Based on the above scheme, a sliding guide structure is provided between the auxiliary arm 422 and the top of the moving platform 41, and the auxiliary arm 422 moves in the transverse direction relative to the moving platform 41 through the sliding guide structure. The sliding guide structure can be arranged at the top end of the vertical support 44, which can be a sliding block and a sliding rail, or a sliding block and a sliding groove. A hydraulic cylinder or other driving mechanism is used to provide a transverse driving force to the auxiliary arm 422.

[0092] For the connecting portion 423 on the lifting frame 42, it can be a lifting ring, and at least two lifting rings are arranged in the length direction of the lifting arm 421 (i.e., in the longitudinal direction), which can meet the needs of lifting the longitudinal beam. The lifting ring can connect the longitudinal beam through a rope.

[0093] Alternatively, the connecting portion 423 can also be a lifting hook that hooks the lifting ring at the top of the longitudinal beam.

[0094] The above technical scheme can realize the lifting of the longitudinal beam. In the construction process, the trolley is used to assemble the intermediate columns 92 in the middle of the station, and the intermediate columns 92 are arranged in the longitudinal direction in sequence and at intervals. Then the trolley is used to carry the intermediate longitudinal beam 95 to the position between the two adjacent intermediate columns 92. The intermediate longitudinal beam 95 is lifted by the lifting frame 42, moved transversely to the position between the two intermediate columns 92 and above the two intermediate columns 92, and then placed on the two intermediate columns 92 after moving into position. Then the intermediate longitudinal beam 95 can be longitudinally clamped by applying a longitudinal clamping force to the intermediate columns 92, and the longitudinal beam assembly is completed.

[0095] In the above scheme, all the intermediate columns can be installed first, and then the intermediate longitudinal beams are assembled; or one intermediate longitudinal beam can be assembled after every two adjacent intermediate columns are completed.

[0096] On the basis of the above technical solutions, the longitudinal beam mounting device 4 can also be used for hoisting, carrying and mounting the center pillar 92. Specifically, a lifting ring or the like structure can be arranged on the top of the center pillar 92 and connected with the connecting portion on the hoisting frame 42, so as to realize hoisting of the center pillar 92.

[0097] Further, the mobile platform 41 is optimized so as to be capable of supporting and fixing the center pillar 92. As shown in Figure 9 the mobile platform 41 comprises two mobile platforms 411 which are parallel and arranged side by side and extend in the transverse direction. The two mobile platforms 411 are spaced apart to accommodate the center pillar 92, and the center pillar 92 is placed between the two mobile platforms 411, and the mobile platforms 411 are used for temporarily fixing and carrying the center pillar 92.

[0098] A specific embodiment is that the cross section of the middle part of the center pillar 92 and the cross section of the top end of the center pillar 92 are both rectangular, and the length of the cross section of the middle part of the center pillar 92 is less than the length of the cross section of the top end of the center pillar 92. The distance between the two mobile platforms 411 is less than the length of the cross section of the top end of the center pillar 92 and greater than the length of the cross section of the middle part of the center pillar 92. Then, the middle part of the center pillar 92 enters the gap between the two mobile platforms 411 and is clamped between the two mobile platforms 411 and cannot fall downward, so that the two mobile platforms 411 realize fixing and supporting of the center pillar 92.

[0099] Further, the outer end of the mobile platform 411 is provided with a locking member 412. A locking rod 413 with a length greater than the distance between the two mobile platforms is used, and the two ends of the locking rod 413 are detachably connected with the locking members 412 on the two mobile platforms 411. The locking rod 413 is used for preventing the center pillar 92 from moving outward, and further improves the reliability during carrying and avoids the center pillar 92 from falling out of the gap between the two mobile platforms 411.

[0100] In addition, a center pillar supporting surface can also be arranged on the end upper surface of the wheel-rail running device 1 corresponding to the longitudinal beam mounting device 4, and the bottom end of the center pillar 92 abuts against the center pillar supporting surface. The center pillar supporting surface can be a concave surface, so as to position the center pillar 92 and improve the stability thereof.

[0101] On the basis of the above technical solutions, the trolley provided in the embodiment also uses a top plate mounting device 5 for realizing self-carrying and assembling of the top plate.

[0102] As shown in Figures 17 to 21 the top plate mounting device 5 comprises a top plate lifting frame 51, a top plate supporting frame 52 and a top plate lifting driving mechanism 53.

[0103] The top plate lifting frame 51 is arranged at the top end of the vehicle frame 2, and can be arranged in a hollow frame structure by a plurality of strip beams arranged along the transverse direction, longitudinal direction and vertical direction, and can be welded at the top end of the vehicle frame 2.

[0104] The top plate supporting frame 52 is arranged at the top end of the top plate lifting frame 51 and can move relative to the top plate lifting frame 51 along the vertical direction, and the top plate supporting frame 52 is used for supporting the top plate. The top plate mentioned below takes the middle top plate 93 as an example for description, and those skilled in the art can apply the technical solutions provided in the embodiment to the assembly of the top plate 94.

[0105] The top plate lifting driving mechanism 53 is arranged between the top plate lifting frame 51 and the top plate supporting frame 52, and is used for providing driving force for vertical movement of the top plate.

[0106] During the construction process, the middle top plate 93 is hoisted by the gantry crane to the top plate supporting frame 52 at the open end of the steel temporary beam, and the top plate supporting frame 52 supports the middle top plate 93. Then the trolley walks to the installation position along the track, adjusts the height of the top plate supporting frame 52 through the top plate lifting driving mechanism 53, so that the middle top plate 93 above the top plate supporting frame 52 is higher than the side wall block 91 and the middle longitudinal beam 95 on both sides. Then the trolley continues to walk towards the direction of the installed middle top plate 93 until it reaches the target position, and the top plate supporting frame 52 and the middle top plate 93 are lowered to the ends of the middle top plate 93 through the action of the top plate lifting driving mechanism 53 to complete the assembly of the middle top plate 93.

[0107] On the basis of the above technical solutions, the embodiment provides an implementation of the top plate supporting frame 52: the top plate supporting frame 52 includes two top plate supporting beams 521, which are arranged in parallel and side by side and are arranged on both sides of the top plate lifting frame 51. The distance between the two top plate supporting beams 521 is less than the length of the top plate. The top plate is placed on the two top plate supporting beams 521 along the direction perpendicular to the top plate supporting beams 521.

[0108] Further, the top plate lifting frame 51 can also move relative to the vehicle frame 2 along the transverse direction, and during the assembly process, the top plate lifting frame 51 moves transversely to adjust the transverse position of the middle top plate 93.

[0109] Further, the extrusion tool 54 is arranged on the upper surface of the middle part of the roof supporting beam 521, and the extrusion tool 54 is movable relative to the roof supporting beam 521. An extrusion driving element is arranged on the roof supporting beam 521 and connected with the extrusion tool 54 for applying a longitudinal driving force to the extrusion tool 54. During the carrying process, the middle roof 93 is placed on the extrusion tool 54. After the middle roof 93 is overlapped on the side wall block 91 and the middle longitudinal beam 95 during the assembling process, the extrusion driving element is actuated to drive the extrusion tool 54 to apply a longitudinal extrusion force to the middle roof 93, so as to press the newly assembled middle roof 93.

[0110] The side surface of the middle roof 93 is embedded with a sealing strip, and when the longitudinal extrusion force is applied to the middle roof 93, the sealing strip is tightly pressed between the adjacent middle roofs 93, thereby improving the waterproof effect.

[0111] The above trolley can also carry and assemble the longitudinal beam, the middle column and the roof, thereby reducing the dependence on the portal crane, greatly improving the construction efficiency and shortening the construction period.
