[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in Figure 1 A schematic diagram of a preferred embodiment of a sliding support for a large steel bridge provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the first sleeve and the connecting rod. Figure 3 for Figure 1 The enlarged structural schematic diagram of area A shown illustrates a sliding support for a large steel bridge structure, including: a base 1;
[0021] The base 1 has two sets of supports. A hydraulic cylinder support column 2 is fixedly connected to the upper end of the base 1. Two sets of hydraulic cylinder support columns 2 are also provided. A top beam 3 is fixedly connected to the upper end of each hydraulic cylinder support column 2. A first sleeve 4 is fixedly connected to the right side of one set of top beams 3. A connecting rod 5 is slidably connected to the right end of the first sleeve 4. Limit plates 6 are fixedly connected to both ends of the connecting rod 5. A second sleeve 7 is slidably connected to the right end of the connecting rod 5. The second sleeve 7 is fixedly connected to the top beam 3 of the other set. A first spring 8 is installed inside the first sleeve 4, located on the inner wall of the first sleeve 4. A second spring 9 is installed inside the second sleeve 7 between one side and the corresponding limiting plate 6. The second spring 9 is located between one side of the inner wall of the second sleeve 7 and the corresponding limiting plate 6. A first threaded cylinder 10 is fixedly connected to the right side of the top beam 3 of one group. A positive and negative threaded rod 11 is threadedly connected to the right end of the first threaded cylinder 10. A second threaded cylinder 12 is threadedly connected to the right end of the positive and negative threaded rod 11. The second threaded cylinder 12 is fixedly connected to the top beam 3 of another group. A motor 13 is installed on the left side of the top beam 3 of one group. The output end of the motor 13 is fixedly connected to the positive and negative threaded rod 11.
[0022] A first hydraulic cylinder 14 is provided on the upper end of the base 1. The first hydraulic cylinder 14 is fixedly connected to the base 1. A connecting plate 15 is fixedly connected to the output end of the first hydraulic cylinder 14. A universal wheel 16 is fixedly connected to the bottom of the connecting plate 15, and two sets of universal wheels 16 are provided.
[0023] The upper end of the connecting plate 15 is fixedly connected to a limit rod 17, and there are two sets of limit rods 17. The two sets of limit rods 17 are slidably connected to the base 1. The setting of the limit rods 17 can prevent the connecting plate 15 from rotating, which is beneficial to protecting the first hydraulic cylinder 14.
[0024] The base 1 has a mounting plate 18 fixedly connected to its bottom, and there are four sets of mounting plates 18. Rollers 19 are rotatably connected between two sets of corresponding mounting plates 18.

[0027] The working principle of the sliding support for a large steel structure bridge provided by this utility model is as follows:
[0028] Step 1: During use, the distance between the first threaded cylinder 10 and the second threaded cylinder 12 can be adjusted by rotating the forward and reverse threaded screws 11 driven by the motor 13. At this time, the distance between the two sets of top beams 3 can be adjusted. When the two sets of top beams 3 move, the two sets of limiting plates 6 slide inside the first sleeve 4 and the second sleeve 7 respectively.
[0029] Step 2: The first hydraulic cylinder 14 drives the connecting plate 15 to move downward so that the caster wheel 16 can contact the ground. At this time, it is convenient for the two sets of bases 1 to move. Align the second slot 21 with the first slot 20 of the first set and then insert the rod 22 into the second slot 21 and the corresponding first slot 20. At this time, the roller 19 can be prevented from rotating.
[0030] Compared with related technologies, the sliding support for a large steel structure bridge provided by this utility model has the following advantages:
[0031] The distance between the first threaded cylinder 10 and the second threaded cylinder 12 can be adjusted by rotating the positive and negative threaded rods 11 driven by the motor 13. At this time, the distance between the two sets of top beams 3 can be adjusted. When the two sets of top beams 3 move, the two sets of limiting plates 6 slide inside the first sleeve 4 and the second sleeve 7 respectively. This structure makes it easy to adjust the distance between the two sets of top beams 3, so that the device can be used for bridge precast components of different widths. The connecting plate 15 can be moved downward by the first hydraulic cylinder 14, so that the caster wheel 16 can contact the ground. At this time, it is convenient for the two sets of bases 1 to move. The second slot 21 is aligned with the first slot 20 of a set, and then the insertion rod 22 is inserted into the second slot 21 and the corresponding first slot 20. At this time, the roller 19 can be prevented from rotating. This structure makes it easy to move and fix the equipment.
