Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0014] Reference Figure 1-2 As shown, a bridge and culvert support device for road and bridge construction includes a box body 1 and a base 2 located directly below the box body 1. The box body 1 has openings on the left and right sides, and its bottom is connected to the base 2 via four support members and a hydraulic cylinder 5. An arched plate 6 is installed on its top. The support members consist of support columns 4 and first sleeves 3. The support columns 4 are slidably inserted into the first sleeves 3, and both are connected to the base 2 and the box body 1 respectively. Four vertical second sleeves 7 are fixed to the top of the box body 1. The arched plate 6 has various specifications, and four insertion rods 8 corresponding one-to-one with the second sleeves 7 are fixed to its bottom. The insertion rods 8 are inserted into the second sleeves 7.

[0015] It also includes a screw 9, a lifting seat 10, and two sets of side support assemblies arranged symmetrically on the left and right. The screw 9 is vertically arranged, and its upper and lower ends are rotatably connected to the center of the top plate and the bottom plate of the housing 1, respectively. The screw 9 is also connected to a drive assembly. The center of the lifting seat 10 is provided with a fixing nut 11 that is threadedly connected to the screw 9, and its front and rear ends are slidably connected to the inner wall of the housing 1. More specifically, the inner walls of the front plate and the back plate of the housing 1 are provided with vertical guide rails 21 that are slidably connected to the ends of the lifting seat 10.

[0016] The side support assembly includes a support plate 12, an upper connecting rod 13, a lower connecting rod 15, and a support rod 14. The support plate 12 is vertically arranged, and several abutments 16 are installed on its outer wall. The upper connecting rod 13 and the lower connecting rod 15 are arranged in parallel, with one end of each hinged to one side of the top plate and the bottom plate of the housing 1, respectively, and the other end of each hinged to the inner side of the support plate 12. One end of the support rod 14 is hinged to the middle of the upper connecting rod 13, and the other end is hinged to the side of the lifting seat 10. There are two upper connecting rods 13, two lower connecting rods 15, and two support rods 14. When the lifting seat 10 moves upward, it drives the upper connecting rod 13 to open outward through the support rod 14, thereby causing the support plate 12 to unfold outward.

[0017] Before use, select the appropriate arch plate 6 according to the shape of the top of the bridge and culvert, and then install the selected arch plate 6 on the top of the box body 1.

[0018] In use, place the device at the center of the bottom of the bridge culvert, then start the hydraulic cylinder 5. Its hydraulic rod extends and drives the box 1 to move upward under the support of the support members, thereby driving the arch plate 6 to move upward and make it fit against the top of the bridge culvert, thus supporting the top of the bridge culvert. Subsequently, the drive assembly drives the screw 9 to rotate, and the screw 9 drives the lifting seat 10 to move upward. The upward movement of the lifting seat 10 will drive the two sets of side support components to open outward synchronously until the abutment blocks 16 of the two support plates 12 fit against the side of the bridge culvert, thus supporting the side of the bridge culvert. Example 2

[0019] As a preferred embodiment of this utility model, this embodiment designs the driving component based on Embodiment 1, specifically as follows: The drive assembly is mounted on the top plate of the housing 1, and includes a drive shaft 17, a worm gear mechanism 18, and a mounting bracket 19. The drive shaft 17 is coaxial with the screw 9 and vertically penetrates the top plate of the housing 1. Its lower end is fixedly connected to the upper end of the screw 9. The worm gear mechanism 18 is mounted on the top plate of the housing 1 through the mounting bracket 19. Its worm gear is fixedly mounted on the drive shaft 17, and its worm is connected to a handwheel 20 at the outer end of the worm.

[0020] In use, turning the handwheel 20 drives the drive shaft 17 and screw 9 to rotate via the worm gear transmission, thereby moving the lifting seat 10 up and down. Because the worm gear mechanism 18 has a self-locking property, the support plate 12 will not be forced back after it reaches its position, effectively improving the stability of the device.

[0021] In summary, this device can use arched plates 6 of different specifications. The overall height of the device can be adjusted by hydraulic cylinder 5, and the distance between the two support plates 12 can be adjusted by drive component, thereby enabling support for bridges and culverts of different heights and widths. This device is easy to operate, requires no welding, and can be quickly installed, which helps to ensure the smooth progress of the project.

[0022] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
