[0018] The technical scheme of the present application will be described clearly and completely in combination with the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.
[0019] Embodiment 1
[0020] Reference Figure 1 A bridge maintenance mobile operation platform, comprising a right-angle hanging arm 10 and guide wheels A 11 and B 12 arranged on the inner side of the right angle of the right-angle hanging arm 10 for contacting the top and side of the bridge protection wall, respectively, the end of the right-angle hanging arm 10 is provided with a ladder 20, the bottom of the ladder 20 is provided with a basket frame 30, and the ladder 20 is further provided with a guide wheel C 41 contacting the other side of the bridge protection wall.
[0021] The right-angle boom 10 is a critical structural component of the bridge maintenance mobile operation platform, designed in a right-angle shape to support the entire gondola system. The guide wheel A 11 and the guide wheel B 12 are set inside the right angle of the right-angle boom 10, respectively, to contact the top and side of the bridge parapet. Such a design helps the gondola move horizontally along the bridge parapet through the guide wheel A 11 and the guide wheel B 12. The end of the right-angle boom 10 is equipped with a ladder 20, which not only provides access to the gondola for workers, but also can serve as an auxiliary structure for the gondola to move and position. Set at the bottom of the ladder 20 is the main work area for gondola operations, which can accommodate workers and construction materials. The guide wheel C 41 is set on the ladder 20 to contact the other side of the bridge parapet, working with the guide wheel A 11 and the guide wheel B 12 to ensure stable movement and positioning of the gondola on the bridge parapet.
[0022] The design of the right-angle boom 10 ensures the stability and load-bearing capacity of the gondola structure. The guide wheel A 11 and the guide wheel B 12 allow the gondola to move in a direction on the bridge parapet, while reducing friction with the parapet and reducing wear. The ladder 20 not only provides access to the gondola for workers, but also may assist in positioning and stabilizing the gondola on the bridge through its structural design. The gondola frame 30 serves as a work platform, carrying construction personnel and materials, while the guide wheel C 41 works with the guide wheels A 11 and B 12 to ensure smooth movement of the gondola on the bridge parapet, preventing the gondola from shifting or tilting during construction. Overall, the combination of these technical features provides a more stable, flexible and safe solution for bridge construction gondolas.
[0023] The ladder 20 is equipped with a balancing component 40 that pushes against its reverse movement in the inclined direction, making the ladder 20 perpendicular to the vertical line; the side of the balancing component 40 away from the ladder 20 is connected to the guide wheel C 41.
[0024] The balancing component 40 is a newly added structural component that functions to push against the reverse movement of the ladder 20 in the inclined direction, maintaining the vertical state of the ladder. This component is important for maintaining the stability of the gondola. The side of the balancing component 40 away from the ladder 20 is connected to the guide wheel C 41, ensuring that the balancing component 40 can effectively exert a reverse force on the ladder 20.
[0025] The balancing component 40 is designed to address the problem of tilting of the gondola due to gravity shift in the prior art. When the gondola shifts due to uneven load or other factors during construction, the balancing component 40, through its connection with the guide wheel C 41, exerts a reverse force on the ladder 20. This force counteracts the effects of gravity shift, ensuring that the ladder 20 remains perpendicular to the vertical line, thereby maintaining the stability and horizontal state of the gondola.
[0026] Specifically, when one side of the basket is tilted due to an increase in load, the balancing component 40 will exert a pushing force on the ladder 20 through its connection with the guide wheel C 41. This force will push the ladder 20 to move in the opposite direction to reduce or eliminate the tilt caused by uneven load. In this way, the basket can remain stable even in the case of load changes, reducing the safety risks during construction and improving construction efficiency.
[0027] The balancing component 40 is a component with telescopic function. The telescopic function of the balancing component 40 is to provide a dynamic balancing mechanism to adapt to different loads and gravity distribution that the basket may encounter in different construction stages. When the load of the basket changes or the position of the basket on the bridge changes, the telescopic balancing component 40 can adjust the length or height according to the actual needs. Its design needs to consider various factors in actual use, including the simplicity of operation and functionality in the case of durability. The telescopic balancing component design ideas include but are not limited to the following:
[0028] Mechanical telescopic arm: similar to the principle of crane or telescopic ladder, the balancing component 40 can be designed to consist of multiple telescopic metal rods, which can be achieved by manually rotating or turning the knob or wrench on the rod. Screw lifting mechanism: similar to the working principle of jack, the balancing component 40 can be built-in screw mechanism, by rotating the screw rod to push or pull the telescopic component to realize the length adjustment. Hydraulic or pneumatic telescopic: if compressed air is available on site, consider using pneumatic cylinders to achieve telescopic function.
[0029] The connection between the balancing component 40 and the ladder 20 is hinged. Hinge is a kind of connection that allows two components to rotate relative to each other in a plane, similar to the working principle of door hinge. Hinged connection provides the necessary flexibility, so that the balancing component 40 can be connected with the ladder 20 at different positions and angles, while allowing the balancing component to perform telescopic motion. Hinged connection ensures that the ladder 20 can maintain stable connection with the balancing component when the balancing component 40 telescopes or adjusts, without affecting the stability of the overall structure due to loose or sliding connection.
[0030] The hinged connection enables the balancing member 40 to rotate freely within a plane, which provides an additional degree of adjustment freedom for the balancing basket. When the basket needs to be rebalanced due to a change in load or position, the operator can adjust its length by telescoping the balancing member 40, and the hinge point allows the balancing member to remain connected to the ladder 20 while telescoping and adapting to different angles of adjustment. The balancing member 40 extends through its telescopic function, and the hinge point allows the balancing member to rotate along the hinge axis to adapt to the tilt angle of the ladder 20. The hinge point allows it to remain connected to the ladder 20 during contraction or extension, while adapting to new positions and angles.
[0031] Furthermore, the balancing member 40 is provided with a level gauge 42. This is an instrument for measuring and indicating horizontality, typically consisting of a transparent glass tube filled with liquid and air bubbles. The level gauge 42 is mounted on the balancing member 40 in a convenient location for observing and determining the position of the balancing member. The level gauge 42 is used to monitor and indicate the horizontality of the balancing member 40 in real time, ensuring that the hanging basket remains balanced and stable during construction.
[0032] The spirit level 42 is introduced to provide an intuitive feedback mechanism to help the operator determine whether the balancing component 40 is in the correct extended state, thereby ensuring the balance of the hanging basket. When the hanging basket needs to be adjusted due to changes in load or position, the operator can determine whether the balancing component 40 needs further extension and contraction adjustment by observing the position of the bubble in the spirit level 42. If the bubble is located in the center of the spirit level 42, this usually indicates that the balancing component 40 is in a horizontal state and the hanging basket is also balanced accordingly. If the bubble deviates from the center, this indicates that the balancing component 40 needs further adjustment, and the operator can extend or retract the balancing component 40 accordingly according to the offset direction of the bubble.
[0033] Example 2
[0034] like Figure 3 As shown, the difference from Example 1 is that a pressure equalizing plate 43 is provided on the side of the balancing component 40 close to the guide wheel C 41, and the guide wheel C 41 is set on the pressure equalizing plate 43 and there are multiple guide wheels C 41.
[0035] The pressure equalizing plate 43 is a newly added plate-like structure on the side of the balancing component 40 near the guide wheel C 41. The function of this plate-like structure is to evenly distribute the pressure exerted by the hanging basket frame 30 on the balancing component 40 and the guide wheel C 41. The guide wheel C 41 is no longer provided separately, but is instead mounted on the pressure equalizing plate 43. This design allows multiple guide wheels C 41 to work together to improve the stability and smoothness of the hanging basket on the bridge guard wall. The increased number of guide wheels C 41 helps to disperse the pressure exerted by the hanging basket frame 30 on the pressure equalizing plate 43, while also potentially providing better support and guidance.
[0036] In embodiment 2, the introduction of the equalizing plate 43 is to improve the pressure distribution of the basket frame 30 on the balancing component 40 and the guide wheels C 41. When the basket frame 30 carries construction personnel and materials, the equalizing plate 43 can bear these loads more evenly, reducing the local pressure on the balancing component 40 and the guide wheels C 41, thereby reducing the risk of wear or damage caused by pressure concentration.
[0037] The load of the basket frame 30 is dispersed to multiple guide wheels C 41 through the equalizing plate 43. These guide wheels C 41 are installed on the equalizing plate 43, which can provide smooth sliding and guiding when the basket needs to move along the bridge parapet. Due to the increase in the number of guide wheels C 41, the pressure on each guide wheel is reduced, which helps to reduce friction and wear, improve the service life of the basket and the safety of operation. In addition, the design of the equalizing plate 43 also helps to improve the adhesion of the basket on the bridge parapet, preventing the basket from sliding or deviating during construction.
[0038] It should be noted that the guide wheels C 41 are provided with floating joints, which can be used to connect the equalizing plate 43 or the balancing component 40 to meet the application in embodiment 1 and embodiment 2.
[0039] The design of the guide wheels C 41 adds a floating joint. This joint allows the guide wheels to move or float freely within a certain range, rather than being fixed in a certain position. Due to the presence of the floating joint, the guide wheels C 41 can adapt to different load and pressure conditions while maintaining stability with the connected components.
[0040] The design of the floating joint is to provide additional flexibility and adaptability, especially when the load and pressure of the basket change under different working conditions. When the basket frame 30 carries different weights of load, the floating joint allows the guide wheels C 41 to make slight movements on the equalizing plate 43 or the balancing component 40 to adapt to the changes in load. This slight adjustment helps to maintain the balance and stability of the basket.
[0041] In embodiment 1, if the balancing component 40 needs to be adjusted in length to maintain the balance of the basket, the floating joint can allow the guide wheels C 41 to adjust their position accordingly as the balancing component expands or contracts, ensuring that the guide wheels always maintain good contact with the bridge parapet.
[0042] In embodiment 2, due to the presence of the equalizing plate 43, multiple guide wheels C 41 are installed on the equalizing plate through the floating joint, which can more evenly distribute the load of the basket frame 30. The floating feature of the floating joint allows the guide wheels to adapt to possible slight deformation or displacement of the equalizing plate, ensuring continuous contact of the guide wheels with the parapet and reducing wear caused by uneven load or pressure changes.
[0043] In summary, the introduction of the floating joint enhances the adaptability and flexibility of the guide wheel C 41, and can improve the stability and durability of the hanging basket in both embodiment 1 and embodiment 2, and ensure the safety and efficiency in the construction process.
[0044] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
