[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a bridge maintenance and construction platform, including a base 1. The base 1 provides basic support for the entire construction platform, enabling it to be stably placed at the relevant location on the bridge. A vertical pole 2 is fixedly connected to the upper side of the base 1, connecting the base 1 and a shelf 3, providing vertical support for the shelf 3. The shelf 3 is fixedly connected to the upper side of the vertical pole 2, serving as the operating surface for workers performing bridge maintenance and construction. A side rail 19 is fixedly connected to the upper side of the shelf 3, surrounding the shelf 3 and providing protection against workers or objects falling from it. A connecting shaft 14 is elastically connected to the inner wall of the shelf 3 via a torsion spring 15. The torsion spring 15 allows the connecting shaft 14 to return to its initial state after being subjected to external force. The connecting shaft 14 is rotatably connected to the inner wall of the shelf 3, allowing it to rotate within the inner wall of the shelf 3, facilitating the movement of the fall arrestor 12 and the rotating plate 7. The system provides support and a base for rotation. One end of the torsion spring 15 is fixedly connected to the outer wall of the connecting shaft 14, and the other end of the torsion spring 15 is fixedly connected to the inner wall of the shelf 3. A fall arrestor 12 is fixedly connected to the outer wall of the connecting shaft 14. The fall arrestor 12 plays a protective role in preventing falls and preventing the basket 11 from falling and causing danger due to the sudden breakage of the rope 5. The lower side of the fall arrestor 12 contacts the upper side of the fixing strip 13. The fall arrestor 12 is at a 90-degree angle to the rotating plate 7. The rotating plate 7 is fixedly connected to the outer wall of the connecting shaft 14. The rotating plate 7 can drive the connecting shaft 14 to rotate, thereby controlling the state of the fall arrestor 12. A fixing strip 13 is fixedly connected to the inner wall of the shelf 3. The fixing strip 13 is fixed to the inner wall of the shelf 3 to provide limit and support for the fall arrestor 12. A delivery component is provided on the front side of the side rail 19. The delivery component is used to transport items. A support component is provided on the inner wall of the base 1. The support component is used to support the construction platform.

[0033] Reference Figure 1 , Figure 5 and Figure 6The support assembly includes a support plate 9, which can slide on the inner wall of the base 1. It provides support by cooperating with a rack 10, etc. The outer wall of the support plate 9 is slidably connected to the right inner wall of the base 1. A rack 10 is fixedly connected to the upper side of the support plate 9, and the rack 10 meshes with a gear 16. The rack 10 can move by rotating the gear 16. A connecting block 8 is rotatably connected to the inner wall of the base 1. The connecting block 8 can rotate on the inner wall of the base 1, providing a base for the installation and rotation of the gear 16, locking pin 17, etc. The outer wall of the connecting block 8 is fixedly connected to... There is a gear 16, which meshes with the rack 10. When it rotates, it can drive the rack 10 and the support plate 9 to move. A locking post 17 is elastically connected to the outer wall of the connecting block 8 by a spring 18. The spring 18 provides elastic force to the locking post 17, so that the locking post 17 can be locked into the locking groove on the inner wall of the base 1. The locking post 17 passes through and is slidably connected to the inner wall of the connecting block 8. The lower side of the locking post 17 is locked to the upper inner wall of the base 1. One end of the spring 18 is fixedly connected to the outer wall of the locking post 17, and the other end of the spring 18 is fixedly connected to the outer wall of the connecting block 8.

[0034] Reference Figure 1 and Figure 2 The delivery component includes a motor 6, which provides power to the delivery component and drives the winding roller 4 to rotate. The motor 6 is fixedly connected to the front of the side rail 19. The winding roller 4 is rotatably connected to the inner wall of the side rail 19. A rope 5 is wound on the winding roller 4. The rope 5 can be wound and unwound by the rotation of the winding roller 4, thereby controlling the lifting and lowering of the lifting basket 11. One end of the rope 5 is fixedly connected to the lifting basket 11. The lifting basket 11 is used to place the items to be transported. The lifting and lowering of the items is achieved by the winding and unwound of the rope 5.

[0035] Working principle: The motor 6 starts, driving the winding roller 4 to rotate. When the winding roller 4 rotates, it will wind and unwind the rope 5. When the winding roller 4 winds up the rope, the rope 5 pulls the lifting basket 11 upward, and the lifting basket 11 presses against the anti-fall plate 12, causing it to rotate. The lifting basket 11 enters the shelf 3. When it is necessary to lower the lifting basket 11, the rotating plate 7 is stepped on counterclockwise. The rotating plate 7 drives the anti-fall plate 12 to rotate through the connecting shaft 14, opening the opening to facilitate the lowering of the lifting basket 11.

[0036] When the support position needs adjustment, first pull the locking post 17 upwards to compress the spring 18, causing the lower side of the locking post 17 to disengage from the slot on the upper inner wall of the base 1. Then rotate the connecting block 8, which drives the gear 16 to rotate. The gear 16 meshes with the rack 10, thereby causing the rack 10 and the support plate 9 to slide on the inner wall of the base 1. When the support plate 9 slides to the appropriate position, release the locking post 17. The spring 18 returns to its original deformation, pushing the lower side of the locking post 17 back into the slot on the upper inner wall of the base 1, fixing the position of the connecting block 8, and thus fixing the position of the support plate 9, thereby achieving support for the construction platform.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
