Description

A bridge pushing and sliding device

Technical Field

The utility model relates to the technical field of jacking and sliding, in particular to a jacking and sliding device for a bridge.

Background Art

At present, in the bridge construction technology, due to the complexity of the site, such as crossing expressways, urban railways, high-speed railways, railways, urban main roads, ports with navigation requirements, and important roads with safe driving requirements, etc., affected by such complex working conditions, in order to ensure the safety of construction, it is generally necessary to adopt the method of pushing and sliding to achieve displacement splicing. During the bridge pushing and sliding operation, ensuring the balance of the bridge structure and uniform force on each support point is the key to the successful completion of the pushing and sliding operation.

When some existing bridge pushing and sliding devices are in use, due to factors such as elevation errors generated during the construction of the slideway beams and the asynchronous flexural deformation of multiple slideway beams, the support points of the bridge will be subjected to uneven force during the pushing and sliding process, which will in turn cause the position of the bridge to deviate, resulting in errors at both ends when spliced, causing the end faces of the bridge to not face up. For this reason, the position and angle of the bridge need to be corrected, which is time-consuming and labor-intensive and is not conducive to the subsequent construction and splicing of the bridge.

Therefore, it is necessary to provide a new bridge pushing and sliding device to solve the above technical problems.

The working principle of the bridge pushing and sliding device provided by the utility model is as follows:

When in use, the hydraulic telescopic machine 31 is first retracted to drive the support plate 33 to be lowered to a height lower than the support platform 41, and then the prefabricated bridge is erected on the top of the support platform 41 by a crane for support, and then the hydraulic telescopic machine 31 is driven again to make the support plate 33 installed on the top contact with the bottom surface of the bridge, and the plurality of hydraulic telescopic machines 31 fixed on the surface of the bottom plate 1 are started at the same time to lift the bridge placed on the load-bearing plate 2 out of contact with the support platform 41, and at the same time, the bottom surface of the load-bearing plate 2 is installed in the center. The top block 51 installed will be lifted up together, and at the same time, the driving block 61 will also rise together, so that the bridge is only in contact with the support plate 33 supported by the bottom end, and then the first motor 64 is connected to an external power supply to drive the first screw rod 63 and the driving block 61 to rotate, so that the driving block 61 will move to one end through the first screw rod 63, so that it drives the top block 51 to move to one end, driving the load-bearing plate 2 to slide on the ball 34 installed on the surface of the support plate 33, so that it can lower the load-bearing plate 2 and the support plate 33. The larger part of the friction between the support plates 33 allows the bridge to slide to one end. When it is spliced with another bridge, since the crane cannot be aligned with the bridge at the other end during initial lifting, some angle or distance errors will occur during splicing. At this time, the second motor 71 is first connected to an external power supply to drive the second screw rod 73 to rotate, so that the second screw rod 73 drives the slide plate 72 threadedly connected to it to move laterally, so that the positioning plate 52 connected to the top drives the top block 51 to move laterally, and drives the top block 51 to drive the load-bearing plate 2 to move laterally on the surface of the support plate 33, so that it adjusts the horizontal position of the bridge to align with the other end, and then respectively controls the hydraulic telescopic machines 31 supporting the two lateral ends of the load-bearing plate 2, so that the hydraulic telescopic machines 31 at both ends are slightly extended and retracted, so that the load-bearing plate 2 can be rotated through the top block 51, so that the angle of the bridge can be corrected, and the bridge can be docked.

The utility model provides a bridge pushing and sliding device, firstly, the bridge is hoisted and placed on the top surface of the limiting structure 4 by a crane, and all the supporting structures 3 are driven at the same time to push the load-bearing plate 2 up to contact the bottom surface of the bridge placed on the limiting structure 4, and the bridge is pushed up and separated from the contact with the limiting structure 4 by the combined force of many supporting structures 3 through the load-bearing plate 2, and then the first driving structure 6 is connected to an external power supply to drive the first driving structure 6 to move vertically through the positioning structure 5 installed at the center of the bottom surface of the load-bearing plate 2, so that the bridge slides to one end. When the bridge is spliced, first, By connecting the second driving structure 7 to an external power source, it drives the positioning structure 5 to move laterally, so that the load-bearing plate 2 drives the bridge to move laterally, and the position of the bridge is adjusted. Then, the supporting structure 3 supported by the bottom surface of the load-bearing plate 2 is controlled laterally to make the supporting structures 3 at the left and right ends shrink slightly up and down, so that the load-bearing plate 2 can be driven to rotate slightly through the positioning structure 5, and the angle of the bridge can be adjusted so that the bridge can be docked.
