Description

Technical Field

[0001] This utility model belongs to the technical field of bridge maintenance platforms, and in particular relates to a foldable temporary work platform device for bridge maintenance. Background Technology

[0002] Bridge maintenance projects include tasks such as dismantling existing drainage pipes, installing new drainage pipes, removing landscape lighting strips, and replacing anti-throw nets. These tasks require workers to spend extended periods of time safely working outside the bridge. For example, patent CN211713684U discloses a bridge maintenance platform, including a suspension mechanism and a working platform. The suspension mechanism includes a frame base with counterweights. Trolleys are mounted at both the front and rear ends of the frame base, rolling on tracks laid on the bridge deck along the bridge's length. A crossbeam is fixedly connected to the top of the frame base. The working platform is located at one end of the crossbeam extending beyond the bridge, and the working platform has an L-shaped structure. In this solution, workers can perform maintenance work within the working area of ​​the platform, significantly improving safety and reducing physical exertion, thus increasing efficiency. The suspension mechanism can move along the tracks, reducing the time required to set it up, further improving efficiency. Existing temporary working platform devices for bridge maintenance are bulky and difficult to transport. In view of this, we propose a foldable temporary work platform device for bridge maintenance. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned technical problems by providing a foldable temporary work platform device for bridge maintenance, enabling the bridge maintenance platform to be folded and stored.

[0004] In view of this, the present invention provides a foldable temporary working platform device for bridge maintenance, including a base, an unfolding motor fixedly connected to one end of the base, an unfolding screw fixedly connected to the output end of the unfolding motor, a sliding perforated plate threadedly connected to the outer wall of the unfolding screw, a tilting column movably connected inside the hole of the sliding perforated plate, a telescopic seat fixedly connected to one end of the tilting column, a tilting groove provided at the connection between the base and the tilting column, a push column fixedly connected to the outer wall of the telescopic seat, a sliding groove provided at the connection between the base and the push column, a rotary motor fixedly connected to the outer wall of the telescopic seat, a connecting frame fixedly connected to the output end of the rotary motor, a hydraulic rod fixedly connected to the inner wall of the connecting frame, a lifting perforated plate fixedly connected to the output end of the hydraulic rod, a tilting plate movably connected inside the hole of the lifting perforated plate, and a maintenance platform fixedly connected to one end of the tilting plate.

[0005] Based on the above structure, the sliding orifice plate slides through the tilting groove to drive the telescopic seat at one end of the tilting column to rotate, flipping the connecting frame on the outer wall of the telescopic seat to one side of the bridge. Then, the hydraulic rod works through the lifting orifice plate to drive the maintenance platform at one end of the tilting plate to rotate, rotating the maintenance platform to a horizontal state. Next, the rotary motor works through the connecting frame to drive the maintenance platform to rotate directly under the bridge, realizing the folding and unfolding operation of the temporary work platform for bridge maintenance.

[0006] Preferably, the flipping groove is arc-shaped, and the flipping groove and the sliding groove are distributed in a "Y" shape. In this embodiment, it is convenient for the sliding plate to slide and drive the flipping column to slide along the inner wall of the sliding groove. Then, the sliding plate slides through the flipping groove to drive the telescopic seat at one end of the flipping column to rotate, thereby realizing the flipping and unfolding operation of the telescopic seat.

[0007] Preferably, the telescopic seat forms a flipping structure with the base through a flipping groove and a sliding groove. In this embodiment, it is convenient for the sliding plate to slide through the flipping groove to drive the telescopic seat at one end of the flipping column to rotate, flipping the connecting frame on the outer wall of the telescopic seat to one side of the bridge.

[0008] Preferably, the cross-section of the maintenance platform is "H" shaped. In this embodiment, by setting the maintenance platform with an "H" shaped cross-section, it is beneficial to improve the structural strength of the maintenance platform and avoid deformation of the maintenance platform.

Connecting holes are provided at both ends of the lifting plate, and rotating plates that are movably connected to the inner wall of the maintenance platform are provided at both ends of the connecting holes. A lifting column is movably connected to one end of the rotating plate, and a guardrail is fixedly connected to the top of the lifting column. A limit post is provided at the bottom of the guardrail. In this embodiment, maintenance personnel use the protective screw to drive the connecting holes at both ends of the lifting plate to slide vertically. The connecting holes, through the rotating plates, lift the guardrail at the top of the lifting column to above the maintenance platform, thus achieving protective operation of the maintenance platform and preventing maintenance personnel from falling.

[0010] Preferably, the guardrail forms a telescopic structure with the maintenance platform through a rotating plate and a lifting column. In this embodiment, the connecting plate drives the guardrail at the top of the lifting column to rise above the maintenance platform through the rotating plate, thereby realizing the protection operation of the maintenance platform.

[0011] Preferably, the limiting posts are evenly distributed along the bottom of the guardrail. In this embodiment, this facilitates the vertical sliding of the limiting posts when the guardrail is raised, which helps to improve the stability of the guardrail when it is raised.

This foldable temporary bridge maintenance platform device, through the setting of a connecting frame, slides a sliding perforated plate through a tilting groove to drive the telescopic seat at one end of the tilting column to rotate, flipping the connecting frame on the outer wall of the telescopic seat to one side of the bridge. Then, the hydraulic rod works through the lifting perforated plate to drive the maintenance platform at one end of the tilting plate to rotate, rotating the maintenance platform to a horizontal state. Next, the rotary motor works through the connecting frame to drive the maintenance platform to rotate directly under the bridge, realizing the folding and unfolding operation of the temporary bridge maintenance platform.
