Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a walking device for bridge construction. Background Technology

[0002] Hanging baskets are the main equipment in cantilever construction. According to their structural forms, they can be divided into four types: truss type, cable-stayed type, steel type, and hybrid type. Based on the requirements of concrete cantilever construction process and design drawings for hanging baskets, we comprehensively compare the characteristics, weight, type of steel used, and construction process of various types of hanging baskets. The design principles of hanging baskets are: light weight, simple structure, sturdy and stable, easy to move forward and disassemble, strong reusability, small deformation after stress, etc. In addition, the space under the hanging basket is sufficient to provide a large construction working surface, which is conducive to the construction and operation of steel reinforcement and formwork.

[0003] Chinese Patent No. 201910264248.1 discloses an automatic walking device for bridge hanging baskets, which includes a hydraulic cylinder and a towing slide. The cylinder barrel of the hydraulic cylinder is hinged to the top of the towing slide, and the piston rod is hinged to the front base of the hanging basket. An anchor block is hinged in the middle of the towing slide. The anchor block has pin holes at both ends, and a detachable pin is installed in the pin hole. When the pin is inserted into the pin hole, it is used to prevent the anchor block from rotating in that direction. When the hanging basket needs to move forward, the piston rod of the hydraulic cylinder extends, and the cylinder barrel drives the towing slide forward to the top of the next rectangular hole under the reaction force. Then the piston rod of the hydraulic cylinder retracts, and the anchor block is blocked from clockwise rotation, and its bottom foot is locked into the rectangular hole. The towing slide is temporarily locked on the track, and the hydraulic cylinder drives the hanging basket forward one step. The extension and retraction are repeated in this way to bring the hanging basket into the target construction position. This invention has the characteristics of strong operability, safety and reliability, high construction efficiency, and high degree of automation with manual assistance.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following issues exist: the aforementioned devices move slowly and the anchor blocks are prone to getting stuck, making it impossible to move forward. Therefore, there is an urgent need to design a walking device for bridge construction to solve the above problems. Utility Model Content

The other end of the drive rod 18 is movably connected to the other end of the driven rod 12 through a second rotating shaft 19. Using a bridge construction walking device, the entire hanging basket system can be moved, which is convenient to operate and has good stability.

[0018] Specifically, the drive assembly includes a connecting seat 20, a second connecting block 21, and a cylinder 22.

The bottom surface of the two fixing blocks 31 has a limiting rod 32, which is slidably connected to the two limiting slots 30.

[0022] Optionally, the bottom ends of both limiting rods 32 pass through the limiting slots 30 and are fixed with limiting blocks 33.

[0023] Operating procedures 1. Start the drive motor 15: The rotating rod 16 drives the ring 17 and the drive rod 18 to rotate, and the drive rod 18 pushes the driven rod 12, so that the moving seat 9 moves horizontally along the guide rod 28; 2. The hanging basket 8 moves: The starting cylinder 22 and the piston rod push the slide rod 6 up and down along the slide groove 5 through the fifth connecting block 25, thereby driving the hanging basket 8 to move; 3. Limit protection: The limit rod 32 slides within the limit groove 30, and the limit block 33 prevents the slide rod 6 from disengaging from the horizontal plate 4.

[0024] Beneficial effects The bridge construction walking device, through the rigid connection of the first side plate 1 and the second side plate 2, combined with the reinforcement design of the vertical plate 3 and the horizontal plate 4, significantly improves the stability and load-bearing capacity of the overall structure, effectively resisting vibration and dynamic loads during construction. The moving seat 9, through the sliding cooperation of the guide block 29 and the guide rod 28, ensures the smoothness and accuracy of horizontal movement, avoiding the problem of easy deviation in traditional devices. The drive motor 15 drives the driven rod 12 through the linkage structure of the rotating rod 16, the ring 17 and the drive rod 18, realizing efficient power transmission. Its mechanical transmission method is simpler and more reliable than the hydraulic system, reducing energy loss and maintenance requirements. The linkage design of the cylinder 22 and the slide rod 6 makes the height adjustment of the hanging basket 8 flexible and convenient. Through the hinged structure of the connecting seat 20, the third connecting block 23 and the fifth connecting block 25, stable lifting and lowering actions are achieved to adapt to the needs of different construction heights. The cooperation of the limiting slot 30 and the limiting rod 32 effectively restricts the movement range of the slide rod 6. Combined with the anti-detachment design of the limiting block 33, it prevents safety hazards caused by the hanging basket moving beyond its limits. The sliding groove 5 and limiting plate 7 on the horizontal plate 4 further enhance the guiding properties of the sliding rod 6, ensuring stability during the lifting process. In addition, the layout of the hanging basket 8 below the guide rod 28 optimizes the center of gravity distribution and reduces the risk of swaying during construction.

[0025] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
