Description

Technical Field

[0001] This utility model relates to the technical field of prefabricated railway stations, and in particular to a prefabricated railway station roof installation mechanism. Background Technology

[0002] Underground stations in urban rail transit engineering refer to station structures built underground. They are core facilities for passengers to board, alight, and transfer in urban rail transit systems such as subways and light rails. The roof slab is an important component of underground stations in urban rail transit engineering.

[0003] When constructing the roof slab, a gantry crane can be used to lift the precast roof slabs one by one from the ground down into the well, where workers can then install them. However, there are multiple horizontal steel pipe supports inside the well, and when the gantry crane moves and lifts the precast roof slabs down into the well, collisions between the precast roof slabs and the horizontal steel pipe supports can easily occur, leading to significant safety hazards. Utility Model Content

[0004] The present invention aims to provide a prefabricated station roof installation mechanism to solve the aforementioned problems that pose significant safety hazards.

[0005] Therefore, the technical solution adopted by this utility model is as follows: a prefabricated station roof installation mechanism, including a car body, a support frame, a U-shaped sliding beam, a roof horizontal hydraulic cylinder, and a roof installation assembly. The roof installation assembly includes a support beam and a roof vertical hydraulic cylinder. The support frame is mounted on the car body, the sliding beam is slidably connected to the support frame, the roof vertical hydraulic cylinder is fixedly connected to the sliding beam and the support beam, and the roof horizontal hydraulic cylinder is fixedly connected to the support frame and the sliding beam.

[0006] As a preferred embodiment of the above scheme, the vehicle body includes two longitudinal steel beams, two first frame beams, and a second frame beam. Three wheels are mounted on the longitudinal steel beams. Frame columns are fixedly mounted on the first frame beams and are fixedly connected to the longitudinal steel beams. The second frame beam is fixedly connected to the two first frame beams, and the support frame is fixedly connected to the two first frame beams.

[0007] More preferably, an outer sliding column is fixedly installed on the sliding beam, and an inner sliding column is fixedly installed on the supporting crossbeam, with the inner sliding column slidably connected to the outer sliding column.

[0008] More preferably, the number of the top plate mounting assemblies is two, and the two top plate mounting assemblies are respectively located at both ends of the sliding beam.

[0009] A further preferred embodiment is that a top abrasion-reducing plate is fixedly provided at the top of the supporting beam.

[0010] More preferably, the wheel is connected to a running motor.

[0011] More preferably, the wheel is connected to a braking device.

[0012] The beneficial effects of this utility model are as follows: This utility model uses a vehicle body, support frame, sliding beam, top plate horizontal hydraulic cylinder, and top plate installation components to enable a gantry crane to lift prefabricated top plates to the underground shaft from a location far from the horizontal steel pipe support. This prefabricated station top plate installation mechanism can be moved underground to the installation position of the top plate for installation, preventing collisions between the prefabricated top plate and the horizontal steel pipe support, reducing safety hazards, and improving construction safety.

[0015] Figure 3 yes Figure 1 Top view. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1-3 As shown, a prefabricated station roof installation mechanism includes a vehicle body, a support frame 5, a U-shaped sliding beam 6, a roof horizontal hydraulic cylinder 14, and a roof installation assembly. The roof installation assembly includes a supporting crossbeam 11 and a roof vertical hydraulic cylinder 7. The support frame 5 is mounted on the vehicle body, the sliding beam 6 is slidably connected to the support frame 5, the roof vertical hydraulic cylinder 7 is fixedly connected to the sliding beam 6 and the supporting crossbeam 11, and the roof horizontal hydraulic cylinder 14 is fixedly connected to the support frame 5 and the sliding beam 6.

[0018] When installing the roof panel, first move the vehicle body to the roof panel installation location, then operate the roof panel horizontal hydraulic cylinder 14. The roof panel horizontal hydraulic cylinder 14 will push the sliding beam 6 to move on the support frame 5. The sliding beam 6 will move the roof panel vertical hydraulic cylinder 7, the support beam 11, and the prefabricated roof panel placed on the support beam 11 together until the roof panel moves to the predetermined position. Then operate the roof panel vertical hydraulic cylinder 7, which will push the support beam 11 and the roof panel upward together until the roof panel moves to the predetermined installation height, at which point the roof panel can be installed.

[0019] The vehicle body includes two longitudinal steel beams 1, two first frame beams 4 and a second frame beam 13. Three wheels 2 are installed on the longitudinal steel beams 1. Frame columns 3 are fixedly installed on the first frame beams 4. The frame columns 3 are fixedly connected to the longitudinal steel beams 1. The second frame beam 13 is fixedly connected to the two first frame beams 4. The support frame 5 is fixedly connected to the two first frame beams 4.

[0020] Two first frame beams 4, two second frame beams 13, and frame columns 3 can connect two longitudinal steel beams 1. Wheels 2 are set on the steel rails underground to facilitate the movement of the vehicle body underground. A planar connection protective net can be connected between the two longitudinal steel beams 1.

[0021] An outer sliding column 9 is fixedly installed on the sliding beam 6, and an inner sliding column 8 is fixedly installed on the supporting crossbeam 11. The inner sliding column 8 is slidably connected to the outer sliding column 9.

[0022] When the supporting beam 11 moves upward, the inner sliding column 8 will move upward together with the supporting beam 11, so that the inner sliding column 8 and the outer sliding column 9 slide relative to each other, and form a guide for the upward movement of the supporting beam 11.

[0023] There are two top plate mounting components, which are located at both ends of the sliding beam 6.

[0024] The two top plate mounting components can support both ends of the top plate, making the position of the top plate more stable.

[0025] A top abrasion reducing plate 10 is fixedly installed at the top of the supporting beam 11.

[0026] The top plate is placed directly on the top wear-reducing plate 10. The top wear-reducing plate 10 can prevent the top plate from directly contacting the support beam 11 and causing wear on the support beam 11, thereby increasing the service life of the support beam 11.

[0027] Wheel 2 is connected to a travel motor 12.

[0028] The traveling motor 12 can provide the rolling power for the wheel 2.

[0029] Wheel 2 is connected to a braking device.

[0030] The braking device can control wheel 2 to stop rolling.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
