[0002] In the construction process of non-pressure box culvert, shear-resistant aluminium alloy formwork is usually used as construction formwork, and sliding construction method is used for construction. This method combines the structural characteristics of non-pressure box culvert, the superior performance of shear-resistant aluminium alloy formwork and the high efficiency of sliding construction, aiming to improve construction efficiency, ensure construction quality and reduce the impact on the surrounding environment.

[0003] In the sliding construction of non-pressure box culvert, the steel mould trolley can be transferred without waiting for the non-pressure box culvert concrete to reach the design requirement. After the transfer of the steel mould trolley, the box culvert concrete will lose support. Since the box culvert concrete has not yet reached the design strength at this time, it is necessary to continue to support the box culvert using a supporting device after the transfer of the steel mould trolley. The existing supporting device generally uses steel pipes and fasteners to support the box culvert. Although this supporting method can play a supporting role, it is very troublesome to assemble steel pipes and fasteners during use. When the box culvert concrete reaches the design strength, the supporting steel pipes and fasteners need to be removed and then reassembled in the next section of box culvert that needs to be supported. At the same time, the steel pipe supporting method requires a large number of steel pipes, making it inconvenient for construction personnel to walk inside the box culvert. Therefore, it needs to be improved. SUMMARY

Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of the utility model protection.

[0021] As Figures 1 to 5As shown, the utility model provides a kind of support device for no pressure box culvert shear aluminium alloy template sliding construction, including bottom plate 1, the top of bottom plate 1 is fixedly installed with fixed frame 2, the top of fixed frame 2 is movably connected with support plate 3, and the front and rear sides of the bottom of support plate 3 are all fixedly installed with mounting plate 4, and the outer surface of mounting plate 4 is movably connected with the inner surface of fixed frame 2, and the inside of the bottom end of mounting plate 4 is fixedly sleeved with fixed shaft 5, and the outer surface of fixed shaft 5 is movably sleeved with cylinder 6, and the top of bottom plate 1 is fixedly installed with track 7, and the outer surface of track 7 is movably sleeved with inclined block 8, and the bottom of inclined block 8 is movably connected with the top of bottom plate 1, and the top of inclined block 8 is movably connected with the outer surface of cylinder 6, and the middle of the inner chamber of fixed frame 2 is movably sleeved with double thread rod 9, and the inside of fixed frame 2 is fixedly installed with round bar 10 located at the left and right sides of double thread rod 9 respectively, and the front and rear sides of the outer surface of double thread rod 9 are all threadedly sleeved with moving plate 11, and the inner surface of moving plate 11 is movably connected with the outer surface of round bar 10, and the left and right sides of moving plate 11 are all hinged with push-pull plate 12, and the other end of push-pull plate 12 is hinged with the inner side of inclined block 8;The number of inclined block 8 is four, and every two of four inclined block 8 is a group, and each group of inclined block 8 is fixedly connected with each other, and two groups of inclined block 8 are symmetrical about double thread rod 9, since the thread direction of the front and rear sides of the outer surface of double thread rod 9 is opposite, when double thread rod 9 rotates, two moving plates 11 will be driven to move towards each other, so that push-pull plate 12 can push inclined block 8 to move away from each other, so that the inclined surface of inclined block 8 extrudes and pushes cylinder 6 to rise, so that mounting plate 4 can drive support plate 3 to rise, so that support plate 3 supports no pressure box culvert.

[0022] Wherein, the front end of the outer surface of double thread rod 9 is fixedly sleeved with first transmission wheel 13, and the front side and rear side of the left and right sides of fixed frame 2 are all fixedly installed with fixed block 14, and the inside of fixed block 14 is movably sleeved with lifting rod 15, and the top of lifting rod 15 is fixedly connected with the bottom of support plate 3;When support plate 3 rises, lifting rod 15 will be driven to rise along the inner surface of fixed block 14, so that support plate 3 can rise more stably.

[0023] Wherein, the front and rear sides of the bottom of bottom plate 1 are all fixedly installed with support rod 16, and the bottom of support rod 16 is fixedly connected with horizontal plate 17, and the bottom of horizontal plate 17 is movably installed with universal wheel 18;Through the setting universal wheel 18, after the concrete of the no pressure box culvert supported by bottom plate 1 as a whole is solidified and the strength reaches the requirement, operating personnel can move bottom plate 1 as a whole to the inside of the box culvert required to be supported next.

[0024] A support block 19 is fixedly installed on the front side of the top of the horizontal plate 17. A movable shaft 20 is movably sleeved inside the support block 19. A handle 21 is fixedly sleeved on the rear end of the outer surface of the movable shaft 20. By setting the support block 19, the support block 19 can play the role of installation and support for the movable shaft 20. The operator can rotate the handle 21 to make the movable shaft 20 rotate inside the support block 19.

[0025] The movable shaft 20 has a second transmission wheel 22 fixedly sleeved on the front side of its outer surface. The second transmission wheel 22 is connected to the first transmission wheel 13 via a transmission belt 23. When the movable shaft 20 rotates, it will drive the second transmission wheel 22 to rotate. The second transmission wheel 22, in cooperation with the transmission belt 23, will drive the first transmission wheel 13 to rotate, thereby enabling the first transmission wheel 13 to drive the double threaded rod 9 to rotate.

[0026] There are two horizontal plates 17, and a fixing plate 24 is fixedly installed on the inner side of each horizontal plate 17. By setting the horizontal plates 17 and placing them on the front and rear sides below the base plate 1, the operator can walk through the bottom of the base plate 1, which improves the convenience of construction.

[0027] The fixing plate 24 has a bolt 25 threaded inside, and a foot pad 26 is fixedly connected to the bottom of the bolt 25. The operator can rotate the bolt 25 to make the bolt 25 move downward inside the fixing plate 24, thereby driving the foot pad 26 to move downward and contact the ground, so that the bottom plate 1 can stay more stably inside the box culvert.

[0028] Working principle and usage process of this utility model:

[0029] When using the equipment, the operator first moves the base plate 1 into the pressureless box culvert that needs support. Then, by rotating the bolt 25, the foot pad 26 moves downward and contacts the ground, so that the base plate 1 can be stably placed inside the pressureless box culvert. At this time, by rotating the handle 21, the handle 21 drives the movable shaft 20 to rotate, which in turn drives the second transmission wheel 22 to rotate. The second transmission wheel 22, in cooperation with the transmission belt 23, enables the first transmission wheel 13 to drive the double threaded rod 9 to rotate.

[0030] When the double threaded rod 9 rotates, it will drive the two moving plates 11 to move towards each other under the limiting action of the round rod 10. This will allow the push-pull plate 12 to push the inclined block 8 to move away from each other under the limiting action of the track 7. This will cause the inclined surface of the inclined block 8 to press and push the outer surface of the cylinder 6, thereby pushing the cylinder 6 to rise. The cylinder 6 will then drive the support plate 3 to rise through the mounting plate 4. When the support plate 3 rises, it will drive the lifting rod 15 to rise along the inner surface of the fixed block 14, thereby making the support plate 3 rise more stably. When the support plate 3 rises and contacts the top of the inner surface of the unpressurized box culvert, it will provide support for the unpressurized box culvert.
