[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] See also Figures 1 to 6 A bridge deck guardrail aerial work platform includes a walking trolley 1, which is a prior art and will not be described in detail here, and further includes:

[0033] The mounting frame 2 is fixedly mounted on the traveling trolley 1;

[0034] Two transverse trusses 3 are fixedly mounted on both sides of the top of the mounting frame 2, and the length direction of the transverse trusses 3 is perpendicular to the moving direction of the traveling trolley 1;

[0035] Two vertical trusses 4, which are respectively arranged at one end of the two transverse trusses 3 away from the traveling trolley 1, and the length direction of the vertical trusses 4 is perpendicular to the length direction of the transverse trusses 3;

[0036] A mobile driving mechanism 5, one side of which is connected to the two vertical trusses 4, and is used to drive the two vertical trusses 4 to move synchronously along their own length direction or synchronously along the length direction of the transverse truss 3;

[0037] A hanging basket 6 is provided at the bottom of the two vertical trusses 4;

[0038] Two counterweights 7 are respectively fixedly mounted on one end of the two transverse trusses 3 away from the hanging basket 6 .

[0039] To ensure safe and smooth operation of U-beams in rail transit, an outward-expanding guardrail design is adopted. This requires high-altitude operations, which poses high safety risks, low operating efficiency, and high economic costs. The existing operation method involves using climbing equipment under the bridge to reach the bridge deck for formwork installation and removal and related operations. However, due to the influence of the original ground topography, some locations cannot be operated with climbing equipment, resulting in serious delays in construction schedules and increased economic costs.

[0040] To this end, the present application sets the hanging basket 6 at the bottom of the vertical truss 4, and drives the vertical truss 4 to move along the length direction of the transverse truss 3 through the mobile driving mechanism 5, even if the hanging basket 6 is extended out of the bridge deck for operation, and drives the vertical truss 4 to move along its own length direction through the mobile driving mechanism 5, that is, the height of the hanging basket 6 can be adjusted to adapt to the installation and disassembly of the template and related operations, and the walking trolley 1 can move along the bridge deck, so that the entire working platform can move along the direction of the bridge deck for operation, thereby improving the efficiency of high-altitude operations, and by providing two counterweight blocks 7, the working platform can be made more stable, ensuring safety during operation.

[0041] In one embodiment of the present invention, the mobile drive mechanism 5 includes two mobile drive components, which are respectively arranged on opposite sides of the two vertical trusses 4. The mobile drive components include a guide 50, a fixed frame 51, a winding roller 52, a sling 53, a rotation drive member 54 and a transverse drive member. The guide 50 is arranged on the fixed frame 51. The guide 50 is used to limit the vertical truss 4 on one side to move along its own length direction. The outer side walls of the two ends of the winding roller 52 are respectively rotatably connected to the fixed frame 51. One end of the sling 53 is wound around the outside of the winding roller 52, and the other end of the sling 53 is wound around the outside of the winding roller 52. One end is fixedly connected to the bottom end of the adjacent vertical truss 4, and one end of the winding roller 52 is connected to a rotary drive member A 54 for driving it to rotate around its own axis. The rotary drive member A 54 includes a motor and a reducer. The motor is fixedly mounted on the fixed frame 51, and the output shaft end of the motor is connected to the input end of the reducer. The output end of the reducer is connected to the end of the winding roller 52, so that the winding roller 52 can be driven to rotate under the drive of the motor and the transmission of the reducer to realize the retraction and release of the sling 53. One side of the fixed frame 51 is connected to a horizontal drive member for driving it to move along the length direction of the horizontal truss 3;

[0042] Driven by the A rotating drive member 54, the winding roller 52 rotates, that is, the sling 53 is retracted and extended. At the same time, the guide member 50 limits the vertical truss 4 from moving along its own length direction, so that under the pulling of the sling 53, the vertical truss 4 drives the hanging basket 6 to move up and down, effectively realizing the adjustment of the staff's working area, and under the drive of the horizontal drive member, the fixed frame 51 is moved along the length direction of the horizontal truss 3. When the fixed frame 51 moves, the fixed frame 51 drives the hanging basket 6 to move horizontally through the guide member 50, the sling 53 and the vertical truss 4, realizing the extension and retraction of the hanging basket 6 and adjusting the distance between the hanging basket 6 and the edge of the bridge deck.

[0043] In one embodiment of the present invention, the guide members 50 are two guide rails, one side of each guide rail is fixedly connected to the fixing frame 51 adjacent thereto, and the inner side walls of each guide rail are slidably connected to the vertical trusses 4 adjacent thereto;

[0044] By fixing the two guide rails on the fixing frame 51 , under the limitation of the guide rails, the vertical truss 4 can only move along its own length direction relative to the fixing frame 51 .

[0045] In one embodiment of the present invention, the transverse driving member includes four rollers 55. The lower sides of the four rollers 55 are respectively connected to the adjacent transverse trusses 3 for rolling connection. The one side of the four rollers 55 is respectively connected to a B rotating driving member 56 for driving the rollers 55 to rotate around their own axes. The B rotating driving member 56 is a motor and is fixedly mounted on the fixed frame 51.

[0046] Driven by the B rotating drive member 56 , the rollers 55 can be driven to rotate, and the four rollers 55 move along the transverse truss 3 , thereby driving the hanging basket 6 to move through the fixed frame 51 , the sling 53 , the guide member 50 and the vertical truss 4 .

[0047] In one embodiment of the present invention, a transverse tie rod is provided between the two fixing frames 51 , and both ends of the transverse tie rod are fixedly connected to the two fixing frames 51 respectively.

[0048] In one embodiment of the present invention, the bottom ends of the two vertical trusses 4 are fixedly connected to the hanging basket 6 respectively.

[0049] When designing a rail transit bridge, a long uphill or downhill section is designed according to the terrain to allow the subway to run more smoothly. However, when installing and disassembling the template and performing related operations on such a sloping bridge, since the walking trolley 1 is walking on the bridge deck, the hanging basket 6 has a certain tilt angle when operating on such a bridge with an inclined angle, which affects the safety of the workers and the efficiency during construction. For this reason, in one embodiment of the present utility model, a rotating shaft 9 is fixedly installed at the bottom end of one of the vertical trusses 4, and both ends of the rotating shaft 9 are respectively rotatably connected to the hanging basket 6. The end of the hanging basket 6 away from the rotating shaft 9 is connected to an adjusting drive assembly 8 for driving it to rotate around the axis of the rotating shaft 9, and the adjusting drive assembly 8 is installed at the bottom end of the other vertical truss 4;

[0050] By adjusting the driving component 8 to drive the hanging basket 6 to rotate around the axis of the rotating shaft 9, the inclination angle of the hanging basket 6 can be adjusted to adapt to the installation and disassembly of the template and related operations on the sloped bridge, thereby improving the safety performance and work efficiency of the equipment.

[0051] In one embodiment of the present invention, the adjustment drive assembly 8 includes a guide column 81, an adjustment drive member 82 and two guide plates 83. The two guide plates 83 are symmetrically arranged and fixedly mounted on the hanging basket 6. A guide groove 84 is formed on each of the two guide plates 83. The inner wall of the guide groove 84 is slidably connected to the outer wall of the guide column 81. One side of the guide column 81 is connected to the adjustment drive member 82 for driving it to move along the length direction of the vertical truss 4.

[0052] Driven by the adjusting drive member 82, the guide column 81 moves along the length direction of the vertical truss 4, and the guide column 81 moves along the inner wall of the guide groove 84. Under the push of the guide column 81, the two guide plates 83 jointly drive the hanging basket 6 to rotate around the axis of the rotating shaft 9, thereby realizing the adjustment of the inclination angle of the hanging basket 6 and effectively improving the practicality of the working platform.

[0053] In one embodiment of the present invention, the adjustment drive member 82 includes a mounting plate 821, a connecting frame 822, a guide rod 823 and a screw 824. The bottom end of the connecting frame 822 is fixedly connected to the guide column 81, the top end of the connecting frame 822 is slidably connected to the outer wall of the guide rod 823, the two ends of the guide rod 823 are respectively fixedly connected to the mounting plate 821, one side of the mounting plate 821 is fixedly connected to the adjacent vertical truss 4, the outer wall of the screw 824 is threadedly connected to the top end of the connecting frame 822, and both ends of the screw 824 are rotatably connected to the mounting plate 821;

[0054] When the tilt angle of the hanging basket 6 needs to be adjusted, the screw 824 is rotated. Under the restriction of the guide rod 823, the connecting frame 822 can only move along the length direction of the vertical truss 4. When the screw 824 is rotated, the connecting frame 822 drives the rotating shaft 9 to move along the length direction of the vertical truss 4. The structure is simple and stable, and easy to operate.

[0055] In one embodiment of the present invention, a corresponding control unit can be provided for use in conjunction with the present invention. The control unit can be selected from any controller and connected to the electrical components in the present application to control the opening and closing operations of the electrical components. This part is prior art. Here, a single-chip microcomputer can be provided as a control unit for demonstration. The single-chip microcomputer in this embodiment is a typical embedded microcontroller (Microcontroller Unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., and is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware required) and cost saving. Its greatest advantage is that it is small in size and can be placed inside the instrument, but it has a small storage capacity, a simple input and output interface, and low functional consumption.

[0056] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
