[0018] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 6This invention provides a technical solution: a mobile construction frame for bridge gap construction, comprising: several support rods 1 and a base plate 25. The support rods 1 are all L-shaped and symmetrically arranged at the left and right ends of the base plate 25. The base plate 25 is located at the lower end between two rows of support rods 1. A reinforcing rod 1 3 is fixedly installed between the lower ends of each row of support rods 1, and a reinforcing rod 2 4 is fixedly installed between the upper ends of each row of support rods 1. The reinforcing rods 1 3 and 2 4 fix each row of support rods 1 together and reinforce the support rods 1. The upper and lower sides of the front and rear ends of the left and right rows of support rods 1... Each support rod is equipped with a fixed cylinder 8. The base plate 25 is fixedly installed on the upper end of the fixed cylinder 8 located on the lower side. Each fixed cylinder 8 has a sliding rod 9 slidably connected to both ends on the left and right sides. The end of the sliding rod 9 away from the fixed cylinder 8 is fixed to the inner side wall of the support rod 1, thus fixing the fixed cylinder 8 and the base plate 25. When in use, the worker can stand on the upper end of the base plate 25, and the two rows of support rods 1 on the left and right sides can move inward or outward. The sliding rod 9 slides in the fixed cylinder 8, thereby changing the distance between the two rows of support rods 1, making it easier to place the support rods 1 in bridge gaps of different widths, making it more convenient to use.

[0020] Each row of support rods 1 has a shaft 6 fixedly installed on the outer side of the upper end of the front and rear ends. Each shaft 6 has a roller 7 rotatably connected to its outer wall. When the support rod 1 is placed in the gap of the bridge, the upper end of the support rod 1 overlaps with the upper end of the bridge through the roller 7, fixing the support rod 1 in place. By pushing the roller 7 of the support rod 1 to move it on the upper end of the bridge, it is easy to move the support rod 1 and facilitate construction at different locations on the bridge. The operation is simple and quick.

[0021] Each fixed cylinder 8 has an mounting plate 12 fixedly installed on its inner end side wall. Two mounting plates 12 on the same side are rotatably connected to a threaded rod 13. Several threaded sleeves 14 are threadedly fitted on the outer wall of the threaded rod 13. Each threaded sleeve 14 is rotatably connected to a drive rod 15 at both ends. The other end of the drive rod 15 is rotatably installed on the side wall of the support rod 1. The upper ends of the two threaded rods 13 are connected to a drive component. The drive component can drive the threaded rods 13 to rotate. When the threaded rods 13 rotate, they drive the threaded sleeves 14 to move. When the threaded sleeves 14 move, they push the drive rods 15 to move. The drive rods 15 drive the two rows of support rods 1 to move away from or closer to each other, so as to change the distance between the two rows of support rods 1.

[0022] The driving components include a long rod 23, a first steering gear 16, a rotating cylinder 17, and a second steering gear 21. Rotating plates are rotatably connected to both ends of the long rod 23. The lower ends of the rotating plates are fixed to the upper ends of the mounting plates 12. One end of the long rod 23 passes through the rotating plate and is fixedly mounted with a handle 24. The long rod 23 is rotatably mounted on the upper ends of the two mounting plates 12. By gripping the handle 24, the long rod 23 can be easily driven to rotate. Two rotating cylinders 17 are provided, located on the front and rear sides of the long rod 23 respectively. The rotating cylinders 17 are rotatably mounted via support seats. Mounted on the upper end of the mounting plate 12, the rotating cylinder 17 can rotate on the upper end of the mounting plate 12. A limit groove 18 is opened at the inner end of the rotating cylinder 17. A rotating rod 19 is inserted into one end of the rotating cylinder 17. A limit block 20 is fixedly installed on the outer wall of one end of the rotating rod 19. The limit block 20 slides into the limit groove 18. A fixing plate 22 is rotatably installed on the other end of the rotating rod 19. The fixing plate 22 is fixed on the outer wall of the support rod 1. When the rotating rod 19 rotates, it can drive the rotating cylinder 17 to rotate. At the same time, the rotating rod 19 can also slide inside the rotating cylinder 17.

[0023] Steering gear 16 is fixed on the outer wall of threaded rod 13 and rotating cylinder 17 respectively, and the outer walls of two adjacent steering gear 16 are meshed with each other. Steering gear 21 is fixed on the outer wall of rotating rod 19 and long rod 23 respectively, and the outer walls of two adjacent steering gear 21 are meshed with each other. Specifically, the long rod 23 is driven to rotate by rotating handle 24. When the long rod 23 rotates, it drives rotating rod 19 to rotate through steering gear 21. When rotating rod 19 rotates, it drives threaded rod 13 to rotate through steering gear 16. When threaded rod 13 rotates, it drives threaded sleeve 14 to move. When threaded sleeve 14 moves, it pushes drive rod 15 to move. Drive rod 15 drives the two rows of support rods 1 to move away from or closer to each other, so as to change the distance between the two rows of support rods 1.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, a plurality of connecting cylinders 10 are uniformly fixedly installed on the inner end sidewall of one row of support rods 1, and a plurality of moving rods 11 are uniformly fixedly installed on the inner end sidewall of another row of support rods 1. One end of the moving rod 11 is slidably inserted into the connecting cylinder 10. A connecting rod 5 is provided at the upper end of the support rod 1. The connecting rod 5 is U-shaped, and a sliding sleeve is fixedly installed on the lower side of both ends of the connecting rod 5. The two sliding sleeves are respectively slidably sleeved on the upper ends of the support rods 1 on both sides. More specifically, when the two rows of support rods 1 move, one end of the moving rod 11 slides in the connecting cylinder 10 to guide and limit the support rod 1. At the same time, the sliding sleeve slides on the upper end of the support rod 1 to limit and guide the two rows of support rods 1 again.

[0025] like Figure 3 and Figure 6As shown, in some embodiments, the left and right ends of the base plate 25 are provided with insertion slots, and a slide plate 26 is slidably connected through the insertion slots. The end of the slide plate 26 away from the insertion slot is fixed to the lower end of the support rod 1. More specifically, when the two rows of support rods 1 move, the slide plate 26 slides in the insertion slot to block the lower end between the two rows of support rods 1, making it easier for the worker to stand.

[0026] like Figure 3 As shown, in some embodiments, the lower outer wall of the support rod 1 is rotatably connected to a guide wheel 2. More specifically, when the support rod 1 is placed in the gap of the bridge, by driving the two rows of support rods 1, the guide wheel 2 on the outer side of the support rod 1 comes into contact with the outer wall of the bridge, which facilitates pushing the support rod 1 and changing its position.

[0027] When this device is in operation, during construction work on the gaps of a bridge, the lower end of the device is placed in the gap of the bridge, and the support rod 1 is placed in the gap of the bridge. The roller 7 overlaps the upper end of the bridge. By turning the handle 24, the long rod 23 is driven to rotate. When the long rod 23 rotates, it drives the rotating rod 19 to rotate through the second steering gear 21. When the rotating rod 19 rotates, it drives the threaded rod 13 to rotate through the first steering gear 16. When the threaded rod 13 rotates, it drives the threaded sleeve 14 to move. When the threaded sleeve 14 moves, it pushes the drive rod 15 to move. The drive rod 15 drives the two rows of support rods 1 to move away from each other, and guides the wheel 2 to contact the outer wall of the bridge, which facilitates the movement of this device and thus facilitates construction work on the gaps of the bridge.
