Description

Technical Field

[0001] The present invention relates to the field of subway construction, and particularly to an assembling device for middle-layer components of an assembled subway station. Background Art

[0002] Existing subway stations and diaphragm walls are all constructed by in-situ casting, that is, by pouring concrete slurry to wrap the steel reinforcement cage, and after the concrete solidifies, it closely combines with the steel reinforcement cage to form the floor slab, wall panel or diaphragm wall of the station. However, it is difficult to ensure the concrete mix ratio during in-situ casting, and the casting site environment is uncontrollable, and it is very easy for foreign objects to invade the unfixed concrete, resulting in the station or diaphragm wall not meeting the design indicators, leaving potential safety hazards for subsequent construction.

[0003] In order to ensure the quality of the building body of the station and the diaphragm wall and improve the construction efficiency, several precast wall panels are now planned to be precast. The precast factory can control the production environment of the precast wall panels and ensure the accurate concrete mix ratio of the precast wall panels or precast floor slabs.

[0004] For an assembled subway station composed of precast components, each precast component of the station needs to be accurately installed in the appropriate position, but existing hoisting equipment such as gantry cranes cannot meet the positioning accuracy requirements for the installation of precast components.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will further describe in detail the specific embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0024] Combined Figures 1 to 3 As shown, it schematically shows the assembling device for the middle-layer components of the prefabricated subway station of the present invention, including a guide rail 1, a rack 2, a side splicing mechanism 3 and an intermediate splicing mechanism 4.

[0025] The guide rail 1 is laid on the top surface of the bottom component 5 of the prefabricated subway station and is arranged along the length direction of the prefabricated subway station. In this embodiment, the number of guide rails 1 is two, and the two guide rails 1 are arranged in parallel.

[0026] The frame 2 is slidably connected to the guide rail 1, which enables the frame 2 to move along the length direction of the prefabricated subway station on the guide rail 1.

[0027] The lateral assembly mechanism 3 is arranged at the end of the frame 2. In this embodiment, the above-mentioned lateral assembly mechanisms 3 are arranged at both ends of the frame 2. The lateral assembly mechanism 3 includes a first positioning device 31 and a pressing device 32. The lateral member 7 of the middle component of the prefabricated subway station is placed on the first positioning device 31. The first positioning device 31 is used to adjust the position of the lateral member 7, and the pressing device 32 is used to press two adjacent lateral members 7 in the length direction of the prefabricated subway station, that is, to press the lateral member 7 to be assembled and the assembled lateral member 7.

[0028] The middle assembly mechanism 4 is arranged on the frame 2. The middle member 6 of the middle component of the prefabricated subway station is placed on the middle assembly mechanism 4. After the lateral member 7 is assembled, the middle assembly mechanism 4 overlaps the middle member 6 on the lateral member 7 to complete the assembly of the middle component of the prefabricated subway station.

[0029] Specifically, the first positioning device 31 includes a first driving component 311, a second driving component 312, a third driving component 313, and a bearing bracket 314 movably connected to the frame 2. The first driving component 311 is used to drive the bearing bracket 314 and the frame 2 to move relative to each other in the X-axis direction. The second driving component 312 is used to drive the bearing bracket 314 and the frame 2 to move relative to each other in the Y-axis direction. The third driving component 313 is used to drive the bearing bracket 314 and the frame 2 to move relative to each other in the Z-axis direction. The X-axis, Y-axis, and Z-axis are perpendicular to each other in pairs. Among them, the first driving component 311, the second driving component 312, and the third driving component 313 can adopt existing hydraulic cylinders. The first driving component 311, the second driving component 312, and the third driving component 313 can drive the bearing bracket 314 to move relative to the frame 2, and then drive the lateral member 7 on the bearing bracket 314 to move, realizing the precise positioning of the lateral member 7.

[0030] A limiting component 315 movably connected to the first positioning device 31 is arranged on the first positioning device 31. The limiting component 315 moves relative to the first positioning device 31 and penetrates into the prefabricated hole of the lateral member 7 or abuts against the lateral member 7. The limiting component 315 can temporarily fix the lateral member 7 on the bearing bracket 314 of the first positioning device 31 to prevent the lateral member 7 from falling off when the bearing bracket 314 moves.

[0031] Further, the pressing device 32 includes a fixed member 321 connected to the frame 2 and a movable member 322 slidably connected to the fixed member 321. The fixed member 321 and the movable member 322 can be driven by a hydraulic cylinder to move relative to each other. The free end of the movable member 322 is detachably connected to the assembled lateral member 7. Of course, a limiting structure is also provided on the bearing bracket 314 for clamping the lateral member 7. When the movable member 322 moves relative to the fixed member 321 to force the bearing bracket 314 to approach the assembled lateral member 7, the limiting structure forces the lateral member 7 on the bearing bracket 314 to move towards the assembled lateral member 7 to press the two adjacent lateral members 7. Among them, the fixed end of the fixed member 321 is rotatably connected to the frame 2, which enables the fixed member 321 and the movable member 322 to rotate relative to the frame 2 about a rotation axis, so as to avoid the lateral member 7 being lifted to the bearing bracket 314.

[0032] There are two pressing devices 32, which are respectively located above and below the bearing surface of the first positioning device 31 to balance the pressing force of the lateral member 7.

[0033] The intermediate assembly mechanism 4 includes a second positioning device 41. The second positioning device 41 includes a fourth driving member 411, a fifth driving member 412, a sixth driving member 413, and a bearing plate movably connected to the frame 2. The fourth driving member 411 is used to drive the bearing plate and the frame 2 to move relative to each other in the X-axis direction. The fifth driving member 412 is used to drive the bearing plate and the frame 2 to move relative to each other in the Y-axis direction. The sixth driving member 413 is used to drive the bearing plate and the frame 2 to move relative to each other in the Z-axis direction. The X-axis, Y-axis, and Z-axis are perpendicular to each other in pairs. The fourth driving member 411, the fifth driving member 412, and the sixth driving member 413 can adopt existing hydraulic cylinders. The fourth driving member 411, the fifth driving member 412, and the sixth driving member 413 can drive the bearing plate to move relative to the frame 2, and then drive the intermediate member 6 on the bearing plate to move, so as to realize the precise positioning of the intermediate member 6.

[0034] In addition, an auxiliary support foot 21 is movably connected to the frame 2. The auxiliary support foot 21 can be extended and supported on the top surface of the bottom component 5 of the prefabricated subway station to temporarily fix the top surface of the bottom component 5 of the prefabricated subway station and the frame 2.

[0035] In summary, the assembling device for the middle-layer components of the prefabricated subway station of the present invention includes a guide rail 1, a frame 2, a side assembling mechanism and an intermediate assembling mechanism. The guide rail 1 is laid on the top surface of the bottom-layer components 5 of the prefabricated subway station and is arranged along the length direction of the prefabricated subway station. The frame 2 is slidably connected to the guide rail 1. The side assembling mechanism 3 is arranged on the frame 2. The side assembling mechanism 3 includes a first positioning device 31 and a pressing device 32. The side components 7 of the middle-layer components of the prefabricated subway station are placed on the first positioning device 31. The first positioning device 31 is used to adjust the position of the side components 7. The pressing device 32 is used to press the side components 7 to be assembled and the side components 7 that have been assembled. The intermediate assembling mechanism 4 is arranged on the frame 2. The intermediate components 6 of the middle-layer components of the prefabricated subway station are placed on the intermediate assembling mechanism 4. After the side components 7 are assembled, the intermediate assembling mechanism 4 overlaps the intermediate components 6 on the side components 7 to complete the assembly of the middle-layer components of the prefabricated subway station.

[0036] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
