As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0031] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] Example 1:

[0033] like Figure 1-5 As shown, a supporting device for highway bridge and culvert construction includes a chassis 1 supported on the ground and a horizontal plate 3 connected to the top of the chassis 1 through a plurality of columns 2.

[0034] The inner wall of the horizontal plate 3 is slidably fitted with two symmetrically arranged movable plates 4. Multiple groups of support components 5 are provided on the top of the horizontal plate 3 and the movable plate 4. The support components 5 include a sleeve 9, a threaded rod 10 and a top block 11. The tops of the horizontal plate 3 and the movable plate 4 are fixedly connected to the mounting seat 6. The bottom of the sleeve 9 is fixedly connected to the connecting ear 8. The inner wall of the connecting ear 8 is fixedly connected to the shaft 7. The shaft 7 is rotatably connected to the inner wall of the mounting seat 6. The threaded rod 10 is connected to the inner wall of the sleeve 9 by threads. The top block 11 is fixedly connected to the top of the threaded rod 10, and the inner walls on both sides of the horizontal plate 3 are provided with avoidance grooves for avoiding the sleeve 9.

[0035] If a rectangular culvert is being constructed, the rotating threaded rod 10 drives the top block 11 to rise vertically until all the top blocks 11 are in contact with the top of the culvert and maintain a certain pressure, thereby providing support for the culvert; if an arched culvert is being constructed, the sleeve 9, threaded rod 10 and top block 11 are rotated along the axis of shaft-7 as the rotation center, and the rotating threaded rod 10 drives the top block 11 to contact the inner wall of the arched culvert. Since the sleeve 9 is rotatable, the supporting direction of the sleeve 9 can be perpendicular to the cross-section of the arched culvert. The lateral components of force acting on the symmetrical sleeves 9 offset each other, and the entire device is only subjected to longitudinal pressure.

[0036] This device drives the threaded rod 10 and the top block 11 to rotate by means of the sleeve 9, which can change the position and angle of the top block 11, so that the top block 11 can contact the inner wall of the bridge culvert of different shapes, thereby being applicable to the support of various bridge culverts and improving the flexibility of the device.

[0037] In this embodiment, a plurality of through holes 12 are formed on the inner wall of the threaded rod 10. A rod-shaped object such as a screwdriver or a plunger is inserted into the through holes 12, thereby saving effort when rotating the threaded rod 10.

[0038] In this embodiment, the inner wall of the horizontal plate 3 is fixedly connected to a guide rod 13 , and the inner wall of the movable plate 4 is rotatably connected to a bidirectional screw rod 14 , and both movable plates 4 are threadedly engaged with the bidirectional screw rod 14 .

[0039] The outer wall of the bidirectional screw 14 is fixedly connected to a bevel gear 15, and the outer wall of the bevel gear 15 is meshed with a bevel gear 2 16. The bevel gear 2 16 is rotatably connected to the inner wall of the horizontal plate 3 through the shaft 2 17. One end of the shaft 2 17 passes through the horizontal plate 3 and is fixedly connected to the adjustment handle 18.

[0040] The rotating adjustment handle 18 drives the second shaft 17 and the second bevel gear 16 to rotate, and the transmission cooperation between the second bevel gear 16 and the first bevel gear 15 drives the bidirectional screw 14 to rotate, so that the two movable plates 4 move horizontally synchronously but in different directions under the limiting guidance of the guide rod 13 and the cross plate 3.

[0041] This device realizes the rotation of the bidirectional screw 14 through the mutual cooperation of bevel gear 1 15, bevel gear 2 16, shaft 2 17 and adjustment handle 18, so that the two movable plates 4 can move outward or inward synchronously, and fold inward when not in use to reduce the occupied area. When in use, it can be flexibly adjusted according to the length of the inner wall of the culvert, thereby further improving the flexibility of the device.

[0042] Example 2:

[0043] A support device for highway bridge and culvert construction, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 1-5 As shown:

[0044] The column 2 includes a base plate 19, a support rod 20 and a top plate 21. The support rod 20 is fixedly connected to the opposite side of the base plate 19 and the top plate 21, and the inner walls of the base plate 19 and the top plate 21 are each provided with a plurality of radially arranged through holes 22. The adjacent base plates 19 and top plates 21 are connected by threads.

[0045] The bottom plate 19 at the bottom is fixed to the top of the chassis 1 by bolts, and the second through hole 22 at the top is fixed to the bottom of the transverse plate 3 by bolts.

[0046] Place the chassis 1 on the ground, then place a column 2 on the top of the chassis 1, and use bolts to fix the bottom plate 19 of the column 2 to the chassis 1. Then stack multiple columns 2 according to the required installation height, and fix two adjacent columns 2 with bolts. Finally, place the cross plate 3 on the top of the top column 2, and fix the two with bolts to complete the splicing of the device.

[0047] By providing a plurality of modular columns 2, the overall height of the device can be flexibly adjusted according to construction requirements, thereby further improving the flexibility of the device.

[0048] Working principle: When using this device, first place the chassis 1 on the ground, then place a column 2 on the top of the chassis 1, and use bolts to fix the bottom plate 19 of the column 2 to the chassis 1. Then, stack multiple columns 2 according to the required installation height, and fix two adjacent columns 2 with bolts. Finally, place the cross plate 3 on the top of the top column 2 and fix the two with bolts to complete the splicing of the device. Then, rotate the adjustment handle 18 according to the width of the culvert. The adjustment handle 18 drives the second shaft 17 and the second bevel gear 16 to rotate. Under the transmission cooperation of the second bevel gear 16 and the first bevel gear 15, it drives the two-way screw rod 14 to rotate, so that the two movable plates 4 move outward synchronously;

[0049] If a rectangular culvert is being constructed, the rotating threaded rod 10 drives the top block 11 to rise vertically until all the top blocks 11 are in contact with the top of the culvert and maintain a certain pressure, thereby providing support for the culvert; if an arched culvert is being constructed, the sleeve 9, threaded rod 10 and top block 11 are rotated along the axis of shaft 7 as the rotation center. Since the sleeve 9 is rotatable, the supporting direction of the sleeve 9 can be perpendicular to the cross-section of the arched culvert. The lateral components of force applied to the symmetrical sleeves 9 offset each other, and the entire device is only subjected to longitudinal pressure. Then the rotating threaded rod 10 drives the top block 11 to contact the inner wall of the arched culvert, thereby providing support for the culvert.

[0050] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
