Description

Technical Field

[0001] The utility model relates to the technical field of construction suspensions, and more specifically, to a bridge side construction suspension. Background Art

[0002] After the construction of the bridge is completed, it is necessary to regularly inspect and repair the bridge, such as crack detection and modification on the side of the bridge, inspection and dredging of drain holes, etc. These are high-altitude operations and require the use of a construction suspension on the side of the bridge for construction or maintenance. Therefore, a construction suspension is proposed for the side maintenance of the bridge.

[0003] After searching, for example, a Chinese patent application with application number CN202322258028.2 discloses a bridge side construction suspension. According to the length of the bridge, the construction suspension composed of multiple connecting frames and an operating table can be combined and spliced. By adjusting the position of the lifting plate inside the rectangular hole, the height of the operating table can be adjusted to meet the needs of engineering personnel for bridge construction. The length of the first support member and the second support member is adjustable, and can be adaptively adjusted according to the characteristics of the bridge, thereby greatly improving the stability of the construction suspension.

[0004] However, when the above technical solution is used, it is necessary to adjust the height of the operating platform when installing the connecting frame. When the staff is repairing the bridge, the height cannot be easily adjusted and it is necessary to climb onto the bridge for disassembly and adjustment, which is rather troublesome. In addition, after the inspection, the suspension must be disassembled with tools, which is troublesome to operate. Utility Model Content

[0028] In order to facilitate installation and disassembly, a bridge abutment clamping device 2 capable of clamping the bridge abutment 5 is provided on one side of the suspension body 1, and is used to install the suspension body 1 on the outer surface of the bridge abutment 5;

[0029] like Figure 3 As shown, the abutment clamping device 2 includes an L-shaped plate 21, which is fixedly arranged on one side of the suspension body 1, and the L-shaped plate 21 is located at the upper end of the abutment 5. A clamping plate 22 is fixedly arranged at the lower end of the L-shaped plate 21, and the clamping plate 22 is located at one side of the abutment 5. A threaded sleeve 23 passes through one side of the L-shaped plate 21, and a threaded rod 24 is threadedly connected to the inner side of the threaded sleeve 23. A rotating handle 25 is fixedly arranged at one end of the threaded rod 24, and a push plate 26 is connected to the other end of the threaded rod 24 through a movable connecting seat. The push plate 26 is located On the other side of the abutment 5, by placing the suspension body 1 on one side of the abutment 5, the L-shaped plate 21 and the clamping plate 22 are placed on the outer surface of the abutment 5. When installing, the handle 25 is manually turned to drive the threaded rod 24 and the push plate 26 forward, so that the abutment 5 is clamped by the push plate 26 and the clamping plate 22, thereby fixing the suspension body 1. When disassembly is required, the handle 25 is reversed to loosen the clamping force of the push plate 26, thereby achieving disassembly, reducing the use of redundant tools and making the operation easier.

[0030] Furthermore, in order to reduce the trouble of manually climbing onto the bridge to dismantle and adjust the height of the operating platform 10, a height adjustment device 3 capable of adjusting the height of the operating platform 10 is provided at the lower end of the suspension body 1, which is used to automatically adjust the height of the operating platform 10 during construction;

[0031] like Figure 4As shown, the height adjustment device 3 includes two vertical frames 31, which are respectively fixedly arranged at the lower end of the suspension body 1, a tooth groove 32 is opened on one side of the vertical frame 31, and a sliding track 33 is arranged on the other side of the vertical frame 31. The outer surface of the vertical frame 31 passes through the inner side of the operating table 10, and a protection plate 36 is fixedly arranged on the inner side of the operating table 10. A gear shaft 35 is movably arranged between the protection plate 36 and the inner wall of the operating table 10, and a rotating gear 34 is fixedly arranged on the outer surface of the gear shaft 35. The rotating gear 34 is meshed and connected with the tooth groove 32. A first roller 37 is movably arranged between the protection plate 36 and the inner wall of the operating table 10, and the two ends of the first roller 37 respectively pass through one side of the protection plate 36 and one side of the inner wall of the operating table 10, and a second roller 38 is movably arranged inside the groove at the lower end of the operating table 10. The first roller 37 and the second roller 38 is movably connected to the sliding track 33, a motor controller 9 is fixedly provided on the inner side of the protection plate 36, one side of the transmission disk 8 is fixedly connected to one end of the gear shaft 35, and the two motors 6 of the same frequency are controlled by the motor controller 9, thereby driving the rotating gear 34 to rotate. Since the rotating gear 34 is meshed and connected with the tooth groove 32, and the gear shaft 35 passes through the protection plate 36 and the inner wall of the operating table 10, the operating table 10 can be driven to climb up and down, and the first roller 37 rolls on the sliding track 33 to clamp the vertical frame 31 to achieve a stable climbing effect. The second roller 38 is movably connected to the sliding track 33, which improves the stability of the operating table 10 during the lifting and climbing process. When repairing the bridge, the operating table 10 can be controlled to be adjusted up and down as a whole, reducing the trouble of manual disassembly and adjustment.

[0032] The working principle is as follows: when the utility model is in use, the utility model is fixed to the abutment 5 by the abutment clamping device 2, and the worker enters the operating platform 10 and uses the height adjustment device 3 to control the motor controller 9 to realize automatic lifting of the operating platform 10. During the lifting process, the rotating gear 34 is prevented from pinching the worker's limbs, and the worker is isolated from the rotating gear 34 by the protective plate 36. When the maintenance is completed, the operating platform 10 is raised to the highest point through the height adjustment device 3, so that the worker can climb onto the bridge body 4 by crossing the operating platform 10, reducing the climbing of ladders, improving the safety of workers, and reducing the use of tools during installation and disassembly as a whole. The efficiency of installation and disassembly is improved, and the trouble of disassembly adjustment is reduced, making the utility model more practical and convenient.
