Description

Technical Field

[0001] This invention relates to the field of suspended platform technology, specifically to a mobile suspended platform for elevated bridge operations. Background Technology

[0002] A suspended platform is a construction tool used for high-altitude operations in building construction, specifically for curtain wall installation and exterior wall cleaning. It is a construction facility erected on a building or structure, using a lifting mechanism to drive a suspended platform that moves up and down along the facade of the building or structure via steel wire ropes; it also serves as a work platform for operators. In the installation of pipelines (water pipes, electrical conduits, and cables) on elevated bridges, drainage pipes and some electrical cables are laid on both sides of the bridge. However, due to the height of the bridge and the fact that the foundation is generally impassable for aerial work platforms, the installation of pipelines is very difficult. Often, suspended platforms are needed to install water pipes, electrical conduits, and cables. However, traditional suspended platforms mostly use steel wire ropes as traction tools. Steel wire ropes have limited ability to resist wind force and will sway when encountering slightly strong winds, resulting in poor safety.

[0003] Therefore, we propose a mobile elevated bridge work platform. Summary of the Invention

[0004] The purpose of this invention is to provide a mobile elevated bridge work platform to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mobile elevated bridge work platform, comprising a mobile vehicle, a suspended platform located beneath the mobile vehicle, and a railing provided on the upper outer surface of the suspended platform. The lifting assembly is located between the mobile vehicle and the lifting platform. The lifting assembly consists of multiple sets of chains and a self-locking motor. The traction of the chains reduces the swing amplitude of the lifting platform during lifting. A safety component is located on one side of the outer surface of the suspended platform, and a sensing component is provided on the lower outer surface of the suspended platform to control the adjustment of the position of the railing by the safety component.

[0006] The self-locking motor is fixedly connected to the outer surface of the mobile vehicle. One end of the output shaft of the self-locking motor is fixedly connected to a drive wheel. The annular outer surface of the drive wheel has an annular groove. The inner surface of the annular groove is fixedly connected to one end of a chain. The end of the chain away from the drive wheel is fixedly connected to the hanging plate. There are two sets of drive wheels, and the two sets are set at a perpendicular angle to each other.

[0007] The lifting assembly also includes a gear, which is fixedly connected to the inner surface of the annular groove. The chain meshes with the gear, and a counterweight is fixedly connected to the end of the chain away from the lifting plate. The chain is U-shaped overall.

[0008] The sensing component includes a ball groove, a rotating ball is rotatably connected inside the ball groove, a conductive sheet is fixedly connected to the inner surface of the ball groove, and a conductive terminal is fixedly connected to the outer surface of the rotating ball.

[0009] The lower end of the wind resistance rod is designed in the shape of a fan blade, and an electromagnet is fixedly connected to the outer surface of the ball groove located on the axis.

[0010] The safety component includes a slide groove, which is formed on the outer surface of the upper end of the suspended platform. A slider is slidably connected inside the slide groove. The upper end of the slider is fixedly connected to a railing. The railing and the suspended platform are slidably connected to the slide groove via the slider. A motor is fixedly connected to the outer surface of one side of the suspended platform. A threaded rod is fixedly connected to the output end of the motor. The threaded rod passes through the slider and is threadedly connected to the slider. There are two sets of railings and sliders.

[0011] The lower outer surface of the suspended platform is fixedly connected to an air storage box. An air inlet is provided on the side of the air storage box away from the motor. A compression plate is slidably connected inside the air storage box. An air supply pipe is fixedly connected on the side of the compression plate away from the air inlet. The air supply pipe passes through the air storage box. An air inlet is provided through the annular outer surface of the air supply pipe. A traction pipe is fixedly connected to the end of the air supply pipe away from the compression plate. The end of the traction pipe away from the air supply pipe is fixedly connected to a set of railings. A ventilation groove is provided at the corresponding position of the railings and the traction pipe. The ventilation groove is connected to the traction pipe. An airbag is fixedly connected to the outer surface of the railings near the inner side. The airbag is connected to the ventilation groove.

[0012] The thickness of the airbag on the side closer to the suspended platform is less than the thickness on the side farther from the suspended platform. The outer surface of the motor away from the suspended platform is rotatably connected to a guide wheel via a rotating shaft. The traction tube is restricted by the guide wheel, and a steel wire rope is embedded inside the traction tube on the side closer to the guide wheel.

[0013] This invention has at least the following beneficial effects: By setting up lifting components and using multiple chains at different angles, the thrust generated by wind at different angles can be countered, thereby improving the stability of the suspended platform under wind conditions. At the same time, when the wind force reaches a certain level, the safety component will reduce the area on the suspended platform that can be used for standing, which, together with the safety rope (existing technology), further increases safety.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1 Please see Figure 1-9 The present invention provides a technical solution: a mobile elevated bridge work platform, including a mobile vehicle 1, a suspended platform 10 below the mobile vehicle 1, and a railing 11 on the upper outer surface of the suspended platform 10. The lifting assembly 2 is located between the mobile vehicle 1 and the lifting platform 10. The lifting assembly 2 consists of multiple sets of chains 23 and a self-locking motor 22. The traction of the chains 23 reduces the swing amplitude of the lifting platform 10 during lifting. The multiple sets of chains 23 are wound up from two directions to limit the swing in other directions. This increases the stability of the bottom lifting platform 10 during lifting and lowering of the lifting platform 10 and in strong winds. Safety component 3 is located on one side of the outer surface of the hanging plate 10. The lower outer surface of the hanging plate 10 is provided with a sensing component 4 for controlling the safety component 3 to adjust the position of the railing 11.

[0018] The self-locking motor 22 is fixedly connected to the outer surface of the mobile vehicle 1. One end of the output shaft of the self-locking motor 22 is fixedly connected to a drive wheel 20. The annular outer surface of the drive wheel 20 is provided with an annular groove 21. The inner surface of the annular groove 21 is fixedly connected to one end of the chain 23. The end of the chain 23 away from the drive wheel 20 is fixedly connected to the hanging plate 10. There are two sets of drive wheels 20, and the two sets are set at a perpendicular angle to each other. The self-locking motor 22 drives the drive wheel 20 to rotate. The annular groove 21 winds the chain 23 inside the annular groove 21. As the amount of chain 23 wound inside the annular groove 21 gradually increases, the lifting speed of the hanging plate 10 will increase. The two sets of chains 23 wound by the two sets of drive wheels 20, one set restricts the swing in the left and right direction, and the other set restricts the swing in the front and back direction, thereby increasing the stability of the hanging plate 10.

[0019] In Embodiment 2, the lifting assembly 2 further includes a gear 24, which is fixedly connected to the inner surface of the annular groove 21. The chain 23 meshes with the gear 24, and a counterweight 25 is fixedly connected to the end of the chain 23 away from the lifting plate 10. The chain 23 is U-shaped. In Embodiment 1, the chain 23 occupies a large volume because it is wound around the drive wheel 20. Therefore, in this embodiment, the chain 23 is no longer wound around the surface of the winding wheel. The chain 23 is driven by the meshing of the gear 24, and the counterweight 25 pulls the chain 23 on the other side tight.

[0020] The sensing component 4 includes a ball groove 40, a rotating ball 41 rotatably connected inside the ball groove 40, a conductive sheet 45 fixedly connected to the inner surface of the ball groove 40, and a conductive terminal 44 fixedly connected to the outer surface of the rotating ball 41. When the working environment is windy, the wind force blows the wind resistance rod 42, causing the rotating ball 41 to rotate inside the ball groove 40. When the conductive terminal 44 contacts the conductive sheet 45, it controls the safety component 3.

[0021] The lower end of the wind resistance rod 42 is designed in the shape of a fan blade. An electromagnet 43 is fixedly connected to the outer surface of the ball groove 40 located on the axis. The electromagnet 43 generates a frictional force on the rotating ball 41 by magnetic attraction. This allows the wind resistance rod 42 to be blown and the rotating ball 41 to rotate inside the ball groove 40 when the wind is strong. This ensures that the sensing component 4 can trigger the safety component 3 when subjected to strong winds, thereby increasing the stability of the device.

[0022] The safety component 3 includes a slide groove 35, which is formed on the upper outer surface of the hanging plate 10. A slider 36 is slidably connected inside the slide groove 35. The upper end of the slider 36 is fixedly connected to the railing 11. The railing 11 and the hanging plate 10 are slidably connected to the slide groove 35 via the slider 36. A motor 30 is fixedly connected to one outer surface of the hanging plate 10. The motor 30 is electrically connected to both the conductive terminal 44 and the conductive sheet 45. A threaded rod 37 is fixedly connected to the output end of the motor 30. The railing 11 and the slider 36 are connected by a thread. There are two sets of railing 11 and slider 36. When the conductive sheet 45 contacts the conductive terminal 44, the motor 30 is energized and drives the threaded rod 37 to rotate. The thread on the surface of the threaded rod 37 is a bidirectional thread. When the threaded rod 37 rotates, the slider 36 drives the railing 11 to move towards the center of the hanging plate 10, reducing the surface area of ​​the hanging plate 10, providing better support for people standing on the surface of the hanging plate 10, improving overall safety, and reducing the psychological burden on users.

[0023] An air storage tank 50 is fixedly connected to the lower outer surface of the hanging plate 10. An air inlet 51 is provided on the side of the air storage tank 50 away from the motor 30. A compression plate 52 is slidably connected inside the air storage tank 50. An air supply pipe 53 is fixedly connected to the side of the compression plate 52 away from the air inlet 51. The air supply pipe 53 passes through the air storage tank 50, and an air inlet 56 is provided through its annular outer surface. A traction pipe 32 is fixedly connected to the end of the air supply pipe 53 away from the compression plate 52. The end of the traction pipe 32 away from the air supply pipe 53 is fixedly connected to a set of railings 11. Ventilation grooves 33 are provided on the railings 11 at positions corresponding to the traction pipe 32, and these grooves are connected to the traction pipe 32. An airbag is fixedly connected to the outer surface of the railings 11 near its inner side. 34. The airbag 34 is connected to the ventilation groove 33. A spring 55 is fixedly connected between the compression plate 52 and the air storage box 50 to facilitate the reset of the compression plate 52. The air supply pipe 53 extends and retracts inside the air storage box 50. When the railing 11 moves towards the center of the hanging plate 10, the air supply pipe 53 and the compression plate 52 are driven to move inside the air storage box 50 through the traction pipe 32. The gas inside the air storage box 50 enters the air supply pipe 53 through the air inlet 56, and is then transported to the ventilation groove 33 through the traction pipe 32. Finally, the airbag 34 expands and opens to prevent the railing 11 from contacting people during the movement and to provide a certain buffer. After the conductive sheet 45 contacts the conductive terminal 44, the self-locking motor 22 starts at the same time to slowly raise the hanging plate 10 and trigger the alarm (the function of the mobile vehicle 1 is not described in detail).

[0024] The thickness of the airbag 34 on the side closer to the hanging plate 10 is less than the thickness on the side farther from the hanging plate 10. When inflated, it will expand along the end with the smaller thickness. The outer surface of the motor 30 away from the hanging plate 10 is rotatably connected to the guide wheel 31 via a rotating shaft. The traction tube 32 is restricted by the guide wheel 31 to prevent the traction tube 32 from deviating from its original position. The guide wheel 31 is not limited to the shape shown in the figure. The traction tube 32 is made of rubber as a whole, and a steel wire rope is embedded inside on the side closer to the guide wheel 31. The main traction force of the traction tube 32 is borne by the steel wire on the inner side to prevent the entire traction tube 32 from being subjected to excessive tensile deformation and to ensure effective gas entry and exit.
