[0035] The implementation principle of the tunnel mobile folding scaffolding of the embodiment of the present application is as follows: when the tunnel mobile folding scaffolding is in use, and when the two sets of scaffolding units 1 are adjusted synchronously, the universal casters 112 are unlocked, and the tunnel mobile folding scaffolding is transferred to the tunnel construction position, and then the two sets of driving motors 113 are adjusted, and the output shafts of the driving motors 113 drive the half-thread screw 114 to rotate synchronously. Since the threaded section of the half-thread screw 114 is threadedly connected with the joint ear piece 115 of the seat plate 111, the half-thread screw 114 drives the two seat plates 111 to approach, and the seat plates 111 are brought closer. The two adjusting rods 121 are moved synchronously, so that the two adjusting rods 121 are close to each other, and the two adjusting rods 121 drive the first hinged rod 1221 connected to the adjusting rod 121 and the second hinged rod 1222 connected to the adjusting rod 121 to move closer to each other, the first hinged rod 1221 drives the first hinged rod 1221 in the adjacent group of hinged parts 122 to move, and the second hinged rod 1222 drives the second hinged rod 1222 in the adjacent group of hinged parts 122 to move, thereby driving the first hinged rod 1221 and the second hinged rod 1222 in the remaining hinged parts 122 to move. The first hinge rod 1221 and the second hinge rod 1222 in the same group move close to each other, so that the scissor-type telescopic frame 12 is stretched. The first hinge rod 1221 and the second hinge rod 1222 move, and the hinge shaft 123 and the rotating shaft 124 move synchronously. The rotating shaft 124 drives the guide slider 134 to slide along the guide groove 133, and the platform frame 131 is supported by the guide slider 134 and the limit block 132. At the same time, due to the increase in the distance between the hinge shaft 123 and the rotating shaft 124, the hinge shaft 123 drives the hinge shaft 123 to move. The strong rod 14 moves, and the strengthening rod 14 drives the sliding block 142 to slide along the sliding groove 141, so as to support the bottom wall of the platform frame plate 131; then, the driving cylinder 136 on each platform frame plate 131 is adjusted, and the piston rod of the driving cylinder 136 drives the sliding block 137 to slide along the sliding groove 135, and the sliding block 137 drives the diagonal support rod 138 to move, and the diagonal support rod 138 drives the cross frame plate 139 to rotate, so that the cross frame plate 139 rotates from a horizontal state to a vertical state, ensuring that the workers on the platform frame plate 131 are protected during the tunnel construction process.

[0036] The double-headed cylinder 22 is adjusted, and the piston rod of the double-headed cylinder 22 applies force to the platform frame plate 131 respectively, so that the two platform frame plates 131 move away from each other, and the platform frame plate 131 applies force to the sliding portion 211, so that the sliding portion 211 slides along the middle supporting portion 212, thereby stretching the transverse telescopic platform 21. At the same time, the platform frame plate 131 drives the telescopic rod 23 to stretch, so as to adjust the distance between the two scaffolding units 1, thereby facilitating the workers to construct the tunnel.

[0037] When the single-side scaffolding unit 1 is adjusted, the universal caster 112 is unlocked, and the tunnel mobile folding scaffold is transferred to the tunnel construction position. Then, one of the drive motors 113 is adjusted, and the output shaft of the drive motor 113 drives the half-thread screw 114 to rotate synchronously. Since the threaded section of the half-thread screw 114 is threadedly connected with the joint ear piece 115 of the seat plate 111, the half-thread screw 114 drives the two seat plates 111 to move closer, and the seat plate 111 drives the adjusting rod 121 to move synchronously, so that the two adjusting rods 121 are close to each other, and the two adjusting rods 121 drive The first hinge rod 1221 connected to the adjustment rod 121 and the second hinge rod 1222 connected to the adjustment rod 121 are moved closer to each other, the first hinge rod 1221 drives the first hinge rod 1221 in the adjacent group of hinged parts 122 to move, the second hinge rod 1222 drives the second hinge rod 1222 in the adjacent group of hinged parts 122 to move, and then drives the first hinge rod 1221 and the second hinge rod 1222 in the remaining hinged parts 122 to move, so that the end of the first hinge rod 1221 in the same group is connected to the second hinge rod The ends of 1222 are close to each other to realize the stretching of the scissor-type telescopic frame 12. The first hinge rod 1221 and the second hinge rod 1222 move while driving the hinge shaft 123 and the rotating shaft 124 to move synchronously. The rotating shaft 124 drives the guide slider 134 to slide along the guide slide groove 133. The platform frame plate 131 is supported by the guide slider 134 and the limit block 132. At the same time, due to the increase in the distance between the hinge shaft 123 and the rotating shaft 124, the hinge shaft 123 drives the reinforcement rod 14 to move, and the reinforcement rod 14 drives the sliding block 142 Slide along the sliding groove 141 to support the bottom wall of the platform frame plate 131; then, adjust the driving cylinder 136 of each platform frame plate 131 on the scissor-type telescopic frame 12 in the stretched state, and the piston rod of the driving cylinder 136 drives the sliding block 137 to slide along the sliding groove 135, and the sliding block 137 drives the diagonal support rod 138 to move, and the diagonal support rod 138 drives the cross frame plate 139 to rotate, so that the cross frame plate 139 rotates from a horizontal state to a vertical state, ensuring that the workers on the platform frame plate 131 are protected during the tunnel construction process.

[0038] While the scissors-type telescopic frame 12 is adjusted, the double-headed cylinder 22 is adjusted, the extended length of the piston rod of the double-headed cylinder 22 becomes longer, and the double-headed cylinder 22 is tilted. At the same time, the platform frame plate 131 on the scissors-type telescopic frame 12 in the stretched state applies force to the sliding portion 211, so that the sliding portion 211 slides along the middle supporting portion 212, thereby stretching the transverse telescopic platform 21 and tilting the transverse telescopic platform 21. At the same time, the platform frame plate 131 on the scissors-type telescopic frame 12 in the stretched state drives the telescopic rod 23 to stretch, and the telescopic rod 23 is tilted, so as to facilitate the lifting and lowering of the single-sided scaffolding unit 1, so as to facilitate the staff to construct one side of the tunnel.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
