[0021] In the above structure, through the structures of the main frame 1, the first bracket 2, the second bracket 3, the third bracket 4, the first connecting plate 5, the first bolt 6, and the second bolt 7, during the use of the traveling device, the user can fix the main frame 1, the first bracket 2, the second bracket 3, and the third bracket 4 by rotating the fourth bolt 16, the first bolt 6, and the second bolt 7. At the same time, the first connecting plate 5 and the second connecting plate 15 are fixedly connected by the threaded connection between the second bolt 7 and the blind hole 14, thereby achieving the effect of quickly assembling the traveling device. And transporting it in the form of parts can facilitate the user to transfer the traveling device, thereby improving the practicability of the traveling device.

[0022] In a preferred implementation mode: the first bracket 2, the second bracket 3, and the third bracket 4 are all fixedly connected to the main frame 1 through the second connecting plate 15 and the first connecting plate 5. The number of the main frames 1 is two, and the two main frames 1 are symmetrically distributed along the outer wall of the first bracket 2.

[0023] In the above structure, by setting the main frame 1, connecting plate one 5 and connecting plate two 15 structure, the running device uses the main frame 1 to bear the force borne by the running device after installation, thereby ensuring the stability of the running device. At the same time, the connecting plate one 5 and the connecting plate two 15 are used to connect the bracket one 2 and the bracket two 3, thereby ensuring that the bracket one 2, the bracket two 3 and the bracket three 4 can share the load force of the main frame 1 during use of the running device, thereby avoiding deformation or even breakage of the main frame 1, thereby improving the stability of the running device and ensuring the load-bearing capacity of the running device.

[0025] In the above structure, through the set slide groove and slide plate structure, the user can adjust the distance between the two clamps 11 by pulling the clamps 11, so that it is convenient for the user to fix the clamps 11 of different thicknesses. At the same time, there is no need for the user to assemble the running device by welding, which not only reduces the user's workload, but also ensures that the running device can perform bridge construction operations on bridge bodies of different specifications.

[0026] In a preferred embodiment, the outer wall of the strong spring 10 is in conflict with the outer wall of the slide plate, and the inner wall of the slide groove is slidably connected to the outer wall of the slide plate.

[0027] In the above structure, by providing the strong spring 10, the slide plate and the slide groove structure, when the user loosens the clamp 11, the elasticity of the strong spring 10 can automatically push the clamp 11 to return to its original position so that the clamp 11 fits tightly with the outer wall of the bracket four 12, thereby ensuring that the bracket four 12 and the clamp 11 cannot shake when the user tightens the bolt three 13, thereby improving the efficiency of the user in assembling the running device.

[0030] In a preferred embodiment, the number of bolts 6 is several, the several bolts 6 are divided into two groups, and the two groups of bolts 6 are symmetrically distributed along the outer wall of the connecting plate 5.

[0031] In the above structure, through the two sets of bolts 6 provided, after the connecting plate 1 is installed, it can not only be fixedly connected to the support 1 through the bolts 6, but also cooperate with the threaded connection between the bolt 7 and the blind hole 14 to reinforce the connection structure between the connecting plate 1 and the support 1, so as to achieve the effects of quickly assembling the traveling device and improving the stability of the traveling device.

[0032] Working principle: First, the user places the two main frames 1 on the bridge body, then places the support 1, the support 2, and the support 3 and the support 4 between the two main frames 1, and then makes the connecting plate 2 and the main frame 1 fixedly connected by tightening the bolt 16. At this time, the user can align the round holes on the support 1, the support 2, and the support 3 with the hole positions on one connecting plate 2, and tighten the bolts 6 one by one so that the three connecting plates 2 are respectively in close contact with the outer walls of the support 1, the support 2, and the support 3, so as to achieve the effect of assembling the traveling device. After tightening the bolts 6, the user can tighten the bolts 7 to make the blind hole 14 and the bolt 7 threadedly connected to achieve the effect of reinforcing the traveling device. Finally, by pulling the two clamping plates 11, the support 4 is placed between the two clamping plates 11, and the bolts 13 are tightened to make the clamping plates 11 and the support 4 fixedly connected.
