[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] In the specific implementation process, such as Figure 1 and Figure 2As shown, a mounting base 1 is provided, with a top plate 2 fixedly mounted on its top. A placement pad 3 is fixedly mounted at the center of the top of the top plate 2. A protective plate 4 is fixedly mounted at the center of the upper surface of the placement pad 3. Rotating wheels 5 are rotatably connected to both sides of the bottom of the mounting base 1 via rotating shafts. Auxiliary wheels 6 are symmetrically provided on both sides of the two rotating wheels 5, and the auxiliary wheels 6 are mutually connected to the lower surface of the mounting base 1. Connecting mechanisms 7 are snapped into both ends of the mounting base 1, and mating grooves 8 are opened at both ends of the mounting base 1 to cooperate with the connecting mechanisms 7. The connecting mechanism 7 includes a connecting rod 9, with mounting grooves 10 opened at both ends of the connecting rod 9. Insert rods 11 are slidably connected in the mounting grooves 10 at both ends of the connecting rod 9. Mounting posts 12 are fixedly mounted at the bottom of the inner parts of the two insert rods 11. An auxiliary spring 13 is sleeved on the outer side of the mounting post 12. An expansion mechanism 19 is symmetrically provided on one side of the mounting base 1.

[0025] It should be noted that when the bridge needs to be assembled, the workers assemble the assembly platform according to the actual assembly requirements. The workers can connect several mounting bases 1 end to end through the connecting mechanism 7 to complete the horizontal assembly of the platform. After that, the workers will extend the mounting bases 1 that have been connected end to end through the expansion mechanism 19 for vertical expansion. In addition, the number of mounting bases 1 can be arbitrarily assembled according to actual needs, which improves the convenience and adaptability of the equipment when using it and can increase the coordination of the bridge during assembly.

[0026] refer to Figure 3 As shown, the connecting mechanism 7 further includes: a sliding column 14, which is slidably connected to the interior of the insertion rod 11; a limiting bolt 15 is threadedly connected to the top end of the insertion rod 11; the bottom end of the limiting bolt 15 is rotatably connected to the top end of the sliding column 14 via a rotating shaft; a plurality of snap-fit ​​balls 16 are slidably connected to the bottom end of the insertion rod 11; and mating seats 17 are fixedly installed at both ends of the lower surface of the connecting rod 9, and the mating seats 17 and the plurality of snap-fit ​​balls 16 are mutually snap-fitted together.

[0027] It should be noted that when connecting the two mounting bases 1 using the connecting mechanism 7, first position the two mounting bases 1. Then, connect the two ends of the mounting base 1 with the connecting rod 9. Subsequently, insert the insertion rod 11 into the mounting groove 10 of the connecting rod 9. As the insertion rod 11 continues to be pressed down, it will contact the mating seat 17 installed at the bottom of the connecting rod 9. Then, the operator moves the mounting post 12, which is slidably connected in the insertion rod 11, downward by using the limiting bolt 15. This will push the snap ball 16, which is slidably connected at the bottom of the insertion rod 11, outward, thereby achieving the snap-fit ​​between the insertion rod 11 and the mating seat 17, thus achieving the connection between the two mounting bases 1 and better assembling the assembly platform.

[0028] refer to Figure 3 As shown, the inner ring of the mating seat 17 has a slot that engages with the locking ball 16, which facilitates the locking of the insertion rod 11 and the mating seat 17.

[0029] refer to Figure 3 As shown, both ends of the connecting rod 9 are symmetrically provided with rotating grooves 18.

[0030] It should be noted that the two mounting bases 1 are connected by the connecting mechanism 7, and the two mounting bases 1 can be rotated through the connecting mechanism 7.

[0031] refer to Figure 4 and Figure 5 As shown, the expansion mechanism 19 includes: two limiting springs 20, which are symmetrically arranged inside the bottom end of the mounting base 1. The ends of the two limiting springs 20 away from the mounting base 1 are fixedly connected to one end of the expansion connecting rod 21, and the expansion connecting rod 21 is slidably connected to the mounting base 1. A pin 22 is slidably connected to the side of the mounting base 1 away from the limiting springs 20, which engages with the expansion connecting rod 21. The bottom end of the pin 22 is provided with a magnetically attracted engagement with the pin 22. The mounting base 1 has a magnet 23 that is fixedly installed inside the mounting base 1. The top of the mounting base 1 is provided with a slot 24 that cooperates with the pin 22 on the side near the pin 22. The bottom of the mounting base 1 is provided with a limiting spring 25 on the side near the extension rod 21. The top of the limiting spring 25 is fixedly connected to the bottom of the locking block 26. The bottom of the locking block 26 is fixedly installed with a pull rod 27. The bottom of the extension rod 21 is provided with a locking groove 28 that cooperates with the locking block 26.

[0032] It should be noted that when two mounting bases 1 need to be assembled longitudinally, the operator pulls the lever 27 downwards, thereby moving the locking block 26 downwards and releasing the restriction of the locking block 26 on the extension link 21. At this time, the extension link 21 extends out of the interior of the mounting base 1 under the elastic force of the limiting spring 20. Then, the distance between the two mounting bases 1 is shortened, and the extension link 21 is inserted into the pin 22 of the mounting base 1. The pin 22 then connects one end of the extension link 21. In addition, the magnet 23 can magnetically restrict the pin 22, thereby completing the position restriction of the pin 22.

[0033] refer to Figure 1 As shown, the mounting base 1 has symmetrical slots on one side that cooperate with the extension link 21.

[0034] It should be noted that this facilitates the longitudinal connection of the two mounting bases 1 via the extension link 21.

[0035] refer to Figure 4 As shown, the end of the extension link 21 away from the limiting spring 20 has a slot that cooperates with the pin 22.

[0036] It should be noted that the extension link 21 can be restricted by the pin 22.

[0038] 1) Equipment assembly: Based on the required bridge size, multiple pieces of equipment are assembled into a platform through the cooperation between the connecting mechanism 7 and the expansion mechanism 19, thus facilitating subsequent bridge assembly work;

[0039] 2) Bridge assembly: The bridge is assembled on the assembled platform. After the bridge assembly is completed, the staff can move the entire platform using the traction device, which allows for the rapid assembly of multi-unit bridges.
