Description

[0002] Bridges and culverts are collectively referred to as bridges and culverts. Bridges are buildings built on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly, and are mainly used to cross obstacles. In the construction of bridges and culverts, in order to facilitate use and improve construction efficiency, an assembled bridge and culvert was invented. Its function is a bridge and culvert structure that is pre-processed and manufactured in a prefabrication yard and then transported to the site for assembly. This structure has the advantages of fast construction speed, good engineering quality, and little impact on the environment.

DETAILED DESCRIPTION

[0025] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] like Figure 1-Figure 6 As shown, the quick assembly device of the assembled bridge culvert provided in this embodiment includes a fixing frame 1 and a connecting frame 2. The fixing frame 1 includes two vertical plates 101 and a horizontal plate 102. The two vertical plates 101 are fixedly connected with the horizontal plate 102 by bolts. A clamping assembly 3 for clamping the passively connected bridge culvert components is provided in the fixing frame 1. Different vertical plates 101 or horizontal plates 102 are used according to the approximate size of the bridge culvert components, and then they are mechanically connected by bolts for easy replacement.

[0027] The connection frame 2 includes two vertical plates 201 and a horizontal plate 202. The two vertical plates 201 are fixedly connected to the horizontal plate 202 by bolts. Different vertical plates 201 or horizontal plates 202 are used according to the approximate size of the bridge culvert components, and then bolts are used to mechanically connect them. The lower end surface of the horizontal plate 202 is fixedly connected with a track strip block 4. A long groove 5 is provided in the track strip block 4. A double-headed threaded rod 6 is rotatably connected in the long groove 5. A sliding block 7 is threadedly connected on the double-headed threaded rod 6. A rotating wheel base 8 is fixedly connected to the sliding block 7. A rotating shaft 9 is rotatably connected to the rotating wheel base 8. A rotating wheel 10 is fixedly connected to the rotating shaft 9. By rotating the double-headed threaded rod 6, the two sliding blocks 7 can move in opposite or opposite directions at the same time.

[0028] The two vertical plates 101 are both fixedly connected with a fixed connecting plate 11 on one side of the side wall by bolts, and the end of the fixed connecting plate 11 away from the vertical plate 101 is fixedly connected with the side wall of the vertical plate 201 by bolts, and the fixed frame 1 is placed on the passively connected bridge culvert component, and then the passively connected bridge culvert component is clamped by the clamping assembly 3, so that the fixed frame 1 can be fixed, and the connecting frame 2 can be fixed by the fixed connecting plate 11, and then according to the size and width of the bridge culvert component that is actively connected, the double-headed threaded rod 6 is rotated through the sliding block 7 to adjust the two rotating wheels 1 0, and then move the actively connected bridge culvert component from the space between the rotating wheels 10. While moving, the side walls of the bridge culvert component rub against the rotating wheels 10, and the rotating wheels 10 can fix the positional relationship of the bridge culvert component, so that it can move along the center line of the passively connected bridge culvert component, and stop after moving to the moving position. At this time, the device can be removed, or the status quo can be maintained. While maintaining the status quo, it can effectively prevent the position between the components from being displaced due to other factors on the construction site, avoiding the trouble of subsequent movement.

[0029] Further, such as Figure 1 as well as Figure 5 As shown, a threaded rod 12 is threadedly connected to the vertical plate 101, one end of the threaded rod 12 is fixedly connected to the rotating shaft 191, two sliding rods 13 are slidably connected to the vertical plate 101, and the two sliding rods 13 both penetrate the vertical plate 101, one end of the sliding rod 13 is fixedly connected to the moving plate 14, the end of the rotating shaft 91 away from the threaded rod 12 penetrates the moving plate 14 and is rotatably connected to the moving plate 14, two threaded rods 2 15 are threadedly connected to the moving plate 14, and the two threaded rods 2 15 are symmetrical and respectively located at the upper and lower positions of the threaded rod 12, and the end of the threaded rod 2 15 away from the moving plate 14 penetrates the vertical plate 10 1, and the threaded rod 15 is not in contact with the vertical plate 101. Both threaded rods 15 penetrate the movable plate 14. The threaded rod 12 and the end of the threaded rod 15 away from the movable plate 14 are fixedly connected with a spline 16 for connecting external power for input and a hand wheel 18 for manual rotation. Rotating the threaded rod 12 can drive the movable plate 14 to move, and then drive the two threaded rods 15 to move. When moving, they do not contact the vertical plate 101, and the spline 16 is convenient for external power equipment to input power, or use the hand wheel 18 to manually rotate the threaded rod 12 or the threaded rod 15.

[0030] Furthermore, Figure 1 , Figure 2 as well as Figure 4As shown, the clamping assembly 3 includes a clamping plate 1 301 and two clamping plates 2 302. The two clamping plates 2 302 are symmetrical and respectively located at the upper and lower positions of the clamping plate 1 301. The side walls of the two clamping plates 2 302 are respectively hinged to the side walls of the clamping plate 1 301. The clamping plate 1 301 is rotatably connected to one end of the rotating shaft 1 91 passing through the movable plate 14. The clamping plate 2 302 is hinged to one end of the threaded rod 2 15 passing through the movable plate 14. The side surfaces of the clamping plate 1 301 and the clamping plate 2 302 away from the movable plate 14 are fixedly connected with elastic anti-skid pads 22. When the threaded rod 12 is moved, the moving plate 14 is driven to move, and then the clamping plate 1 301 and the clamping plate 2 302 are driven to move. When the clamping plate 1 301 contacts the bridge culvert component, according to the shape of the bridge culvert component, if the outer surface is circular, the threaded rod 2 15 can be used to drive the clamping plate 2 302 to move and deflect until it contacts and fits with the outer surface of the bridge culvert component. At this time, the bridge culvert component can be clamped, thereby improving the stability and tightness of the fixed connection of the fixing frame 1 on the bridge culvert component, and facilitating the connection and movement of the bridge culvert component that is actively connected later.

[0031] Furthermore, if Figure 3 as well as Figure 6 As shown, one end of the double-headed threaded rod 6 passes through the long track block 4 and is fixedly connected to the second spline 17. A rotating through hole 19 is opened on the second vertical plate 201. A torsion shaft 20 is movably connected in the rotating through hole 19. One end of the torsion shaft 20 is snap-fitted with the second spline 17, and the other end of the torsion shaft 20 is fixedly connected with a handle 21. The torsion shaft 20 is placed in the rotating through hole 19 and snap-fitted with the second spline 17. Then the handle 21 is used to rotate the double-headed threaded rod 6, which is convenient for loading and unloading and use.

[0032] like Figure 1-Figure 6 As shown, the principle of the quick assembly device of the assembled culvert provided in this embodiment is as follows: when in use, the fixing frame 1 is placed on the passively connected culvert component, and then the clamping assembly 3 is used to clamp the passively connected culvert component, so that the fixing frame 1 can be fixed, and the connecting frame 2 is fixed by fixing the connecting plate 11. According to the size and shape of the passively connected culvert component, the clamping plate 2 302 is used to further tighten it to improve the tightness of the fixing frame 1 fixedly connected to the culvert component. Then, according to the size and width of the actively connected culvert component, the double-headed threaded rod 6 is rotated through the sliding block 7 to adjust the positional relationship between the two rotating wheels 10, and then the actively connected culvert component is moved from the space between the rotating wheels 10. While moving, the side walls of the culvert component on both sides rub against the rotating wheels 10, and the rotating wheels 10 can fix the positional relationship of the culvert component, so that it can move along the center line of the passively connected culvert component, and stop after moving to the moving position. At this time, the positions of the two culvert components correspond.
