Description

Technical Field

[0001] This utility model relates to the field of bridge construction equipment technology, specifically to a mobile suspended platform device for bridge construction. Background Technology

[0002] With the increasing number of bridge projects in municipal engineering, highways, and railways, the investment in auxiliary construction facilities at the bottom or sides of bridges is also gradually increasing. Bridge auxiliary construction typically involves erecting temporary scaffolding or using cranes to transport construction workers. However, using temporary scaffolding usually requires erecting temporary steel pipe frames throughout the entire area under the bridge, which is labor-intensive, costly, and time-consuming. Crane-assisted construction is limited by the bridge construction environment; it cannot be implemented in complex environments such as excessively high bridges or construction on rivers, lacks flexibility, and has limited applicability. Furthermore, neither of these two methods can meet the need for continuous operation at different locations on the bridge.

[0003] Therefore, there is an urgent need to develop a mobile suspended platform device for bridge construction. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a mobile suspended platform device for bridge construction.

[0005] The technical solution of this utility model is: a mobile suspended platform device for bridge construction, comprising a vehicle body, a driver, an auxiliary support frame, a vertical frame, a lifting seat, and a work platform. A horizontal mounting shell is fixed to the top of the vehicle body. The mounting shell has openings on the left and right sides, and horizontal sliding grooves are provided on both the front and rear sides of its inner cavity. A vertical rotating shaft is rotatably mounted at the center of its inner cavity. The upper end of the rotating shaft extends through to the top of the mounting shell, and a gear is fitted on the rotating shaft in the inner cavity of the mounting shell. The driver is mounted on the top of the mounting shell, and its output end is connected to the upper end of the rotating shaft. A crossbeam is slidably mounted in each of the two sliding grooves, and a rack that meshes with the gear is fixed on the opposite surface of the two crossbeams.

[0006] The two auxiliary support frames are located on the left and right sides of the vehicle body, respectively, and are symmetrically arranged. Each of them is fixedly connected to the end of a crossbeam. A horizontal frame is fixed to the outside of the auxiliary support frame. The upper end of the vertical frame is detachably connected to the outer end of the horizontal frame. The lifting seat is vertically slidably mounted on the vertical frame. The two are connected by a lifting drive mechanism. The tail end of the worktable is hinged to the lifting seat. The two are connected by a swing drive mechanism.

[0007] Preferably, the driver is a geared motor.

[0008] Preferably, the auxiliary support frame is arranged longitudinally and includes a main body and a base plate; stiffening plates are provided between the front and rear sides of the main body and the base plate, and a caster wheel is installed on the front and rear sides of the bottom of the base plate.

[0009] Preferably, the worktable is a telescopic worktable with its front end retractable.

[0010] Preferably, the swing drive mechanism includes a hydraulic cylinder, which is horizontally arranged, with one end hinged to the lifting seat and the other end hinged to the worktable.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0018] Reference Figure 1-3As shown, a mobile suspended platform device for bridge construction includes a vehicle body 1, a driver, an auxiliary support frame, a vertical frame 13, a lifting seat 14, and a work platform 15. A horizontally oriented mounting housing 2 is fixed to the top of the vehicle body 1. The mounting housing 2 has openings on both sides, and horizontal sliding grooves 201 are provided on both the front and rear sides of its inner cavity. A vertical rotating shaft 4 is rotatably mounted at the center of its inner cavity. The upper end of the rotating shaft 4 extends through to the top of the mounting housing 2, and a gear 5 is fitted onto the rotating shaft 4 within the inner cavity of the mounting housing 2. The driver is mounted on the top of the mounting housing 2, and its output end is connected to the upper end of the rotating shaft 4 for transmission. A crossbeam 6 is slidably mounted within each of the two sliding grooves 201, and racks 7 that mesh with the gears 5 are fixed to the opposite surfaces of the two crossbeams 6. More specifically, in this embodiment, the driver is a geared motor 3.

[0019] Two auxiliary support frames are located on the left and right sides of the vehicle body 1, respectively. They are symmetrically arranged and each is fixedly connected to the end of a crossbeam 6. A transverse frame 12 is fixed to the outside of the auxiliary support frame. The upper end of the vertical frame 13 is detachably connected to the outer end of the transverse frame 12. The lifting seat 14 is vertically slidably installed on the vertical frame 13. The two are connected by a lifting drive mechanism. The tail end of the worktable 15 is hinged to the lifting seat 14. The two are connected by a swing drive mechanism.

[0020] The auxiliary support frame can improve the overall stability of the device. It is arranged longitudinally and includes a main body 8 and a base plate 9. The front and rear sides of the main body 8 are provided with stiffening plates 11 between the main body 8 and the base plate 9. A caster wheel 10 is installed on the front and rear sides of the bottom of the base plate 9.

[0021] In use, the device is placed on the centerline of the bridge. Then, the positions of the auxiliary support frames on both sides are adjusted according to the bridge width. The reduction motor 3 drives the gear 5 to rotate. Under the transmission of the gear 5 and rack 7, the two auxiliary support frames move in opposite directions under the drive of the crossbeam 6 until they approach the bridge's crash barrier 17. At this point, the transverse frames 12 on both sides extend outwards across the crash barrier 17. Then, the upper end of the vertical frame 13 is connected to the outer end of the transverse frame 12, so that the worktable 15 is suspended at the bottom of the bridge, allowing construction workers to perform bridge construction work on the worktable 15. The height of the worktable 15 is adjusted by the lifting drive mechanism using the lifting seat 14, enabling the device to adapt to bridges of different thicknesses. The vehicle body 1 drives the entire device to move back and forth, allowing it to meet the needs of continuous operation at different locations on the bridge. During the overall movement, when encountering a pier 18, the swing drive mechanism adjusts the worktable 15 from the transverse to the longitudinal direction to prevent interference with the pier 18.

[0022] This device has a simple structure, strong applicability, and is not limited by the construction environment. It can be used on bridges of different widths and thicknesses. The device can be moved back and forth by the vehicle body 1, which enables it to meet the needs of continuous operation at different positions on the bridge. Example 2

[0023] As a preferred embodiment of this utility model, this embodiment modifies the worktable 15 based on Embodiment 1 and designs the swing drive mechanism, specifically as follows:

[0024] To increase the working range of construction workers, the workbench 15 in this embodiment is a telescopic workbench with its front end extendable.

[0025] The swing drive mechanism includes a hydraulic cylinder 16, which is horizontally positioned with one end hinged to the lifting seat 14 and the other end hinged to the worktable 15. When the hydraulic cylinder 16 extends or retracts, it can drive the worktable 15 to swing.

[0026] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
