[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0015] A support device for bridge construction, such as Figure 1-3 When the distance between the two support seats 1 becomes far away, the two control mechanisms can no longer be in contact with each other. At this time, one control mechanism is operated separately to control the operation of one connection mechanism, that is, the screw rods above the two support seats 1 can be controlled to rotate separately. The driving mechanism works to drive the support seat 1 to move to the bottom of the bridge, and then adjusts the distance between the two support seats according to the width of the bridge. When the width of the bridge is small, the two groups of control mechanisms are contacted. By operating one group of control mechanisms, the two groups of control mechanisms are driven to move synchronously, and then the two groups of connecting mechanisms are driven to work, controlling the screw rods 2 on the two support seats 1 to rotate synchronously. The screw rod 2 cooperates with the thread of the nut to control the vertical rod 3 and the support block 4 to move upward. The support block 4 contacts the bridge to provide auxiliary temporary support for the bridge. When the width of the bridge is large, the adjustment mechanism adjusts the distance between the two support seats, and then through the control mechanism, the screw rod on a support seat is separately controlled to rotate, so that the two support blocks can also support the bridge at a long distance. By adjusting the distance between the two support seats, auxiliary support can be provided for bridges of different widths to meet the support requirements of different building materials for the construction of bridges of different widths.

[0016] Specifically, the drive mechanism described in this embodiment includes several grooves 5 formed in the bottom of the support base 1. Cylinders 6 are disposed on the inner walls of the top ends of the grooves 5, and movable wheels 7 are disposed at the bottom ends of the movable ends of the cylinders 6. During operation, the cylinders 6 extend, pushing the movable wheels 7 downward. After the movable wheels 7 contact the ground, the support base 1 begins to separate from the ground. The movable wheels 7, in turn, drive the upper support base 1 to move, moving the support base 1 and other components below the bridge.

[0017] Furthermore, the adjustment mechanism described in this embodiment includes a threaded groove 8 formed on opposing surfaces of the two support blocks 1. A threaded rod 9 is disposed within the threaded groove 8. Opposite ends of the two threaded rods 9 are connected by a connecting block. The threads of the two threaded rods 9 are opposite to each other. Two through holes are formed on opposing surfaces of the two support blocks 1. A guide rod is disposed within the two through holes. The through holes are located at the rear of the side portions of the support blocks, while the threaded groove 8 is located at the front of the side portions of the support blocks. Rotating the connecting block drives the two threaded rods 9 to rotate. Through the threaded engagement of the threaded rods 9 with the threaded groove, and the movement of the movable wheel out of the groove, the distance between the two support blocks 1 can be varied, allowing adjustment according to the width of the bridge.

[0018] Furthermore, the connection mechanism described in this embodiment includes several mating sprockets 10 mounted at the bottom end of the screw rod 2. The sprockets 10 located above the same support block 1 are movably connected by a first chain. The number of mating sprockets 10 corresponds to the number of screw rods 2. A control mechanism controls the rotation of the sprockets 10, driving the synchronous rotation of the several screw rods located above the same support block 1, thereby adjusting the height of the support block according to the height of the bridge.

[0019] Furthermore, the control mechanism described in this embodiment includes a placement groove 11 provided on the inner side of the support base 1, a fixing rod 12 is provided on the inner wall of one side of the placement groove 11, a long strip 13 is provided in the placement groove 11, a matching groove is provided on one side of the long strip 13, the fixing rod 12 is inserted into the matching groove, a rotating rod 14 is movably provided on the top surface of the long strip 13, a gear 15 and a first sprocket 16 are fixedly installed on the rotating rod 14, the gear 15 is located above the first sprocket 16, and a guide groove 17 is provided on the inner wall of the bottom end of the placement groove 11. A guide block is set in the groove 17, and one side of the guide block is connected to the inner wall of one side of the guide groove 17 by a spring. A second sprocket 18 is movably set at the top of the guide block, and a connecting shaft 19 is movably set on the inner wall of the bottom end of the placement groove 11. A third sprocket 20 and a fourth sprocket 21 are fixedly mounted on the connecting shaft 19. The third sprocket 20 is located in the placement groove 11, and the fourth sprocket 21 is located above the support seat 1 and engages with the first chain. The first sprocket 16, the second sprocket 18, and the third sprocket 20 are connected by a second chain. The openings of the two placement slots 11 are opposite to each other, and the guide blocks always move in the guide slots. Magnets are set on the opposite surfaces of the two long plates 13. After the two long plates 13 are pulled out relative to each other, the two magnets generate an adsorption force, causing the two long plates 13 to move relative to each other. At this time, the distance between the two support seats 1 is relatively close, and the two gears 15 are engaged and matched. Rotating one of the rotating rods 14 can drive the two gears to rotate. Through the rotation of the second chain, the connecting shaft 19 can be driven to rotate, which drives the fourth sprocket 21 to rotate, and drives the first chain to rotate, controlling the two The screw on the block support seat 1 rotates synchronously to achieve the effect of controlling the lifting of the two support blocks. The tightness of the second chain can be adjusted by moving the guide block in the guide groove 17 and the action of the spring, that is, the long plate drives the third sprocket 20 to move outward, and the guide block drives the second sprocket 18 to move to avoid the second chain from loosening. Moreover, after the two support seats 1 move in opposite directions and the two gears 15 can no longer engage, the rotating rod can be controlled separately to control the screw on one support seat 1 to rotate synchronously, thereby controlling the support block to perform lifting and lowering movements.

[0020] Furthermore, a buffer plate 22 is positioned above the support block in this embodiment. Several buffer grooves are defined on the top surface of the support block. Several rods are positioned at the bottom of the buffer plate 22. The rods are inserted into corresponding buffer grooves and connected to the inner wall of the bottom end of the buffer grooves via buffer springs. After the buffer plate 22 contacts the bridge, it moves downward. The buffer springs prevent the support block from making hard contact with the bridge, resulting in a more effective operation.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
