[0058] The jacking mechanism 4 is arranged on the top of the trolley body 1 , and the jacking mechanism 4 is located at one side of the waterproof board laying mechanism 2 .

[0059] In this embodiment, a waterproof sheet laying mechanism 2 is installed on the trolley body 1 to drive the waterproof sheet roll to move from one side of the tunnel to the other side, thereby completing the laying construction of the waterproof sheet. At the same time, the waterproof sheet laying mechanism 2 also supports the transportation of longitudinal steel bars from the bottom of the tunnel to the top.

[0060] Finally, the circular steel bar conveying mechanism 3 provided on the side of the trolley body 1 is used to convey the circular steel bar, and the movement of the circular steel bar is restricted by the circular steel bar conveying mechanism 3, so that one end of the circular steel bar is conveyed onto the trolley from one side of the tunnel and moves to the other side of the tunnel to form an arc structure. Then, the lifting mechanism 4 is used to lift the circular steel bar, and the longitudinal steel bar is automatically laid on the top of the tunnel for workers to tie and construct.

[0061] Through this embodiment, the functions of the trolley body 1 are diversified, a convenient conveying mechanism is provided for conveying steel bars, the number of operators is reduced, and the labor intensity is lowered.

[0064] Specifically, the arc track 21 is a double-track structure, one end of the arc track 21 is arranged on one side of the trolley body 1 , and the other end of the arc track 21 is arranged on the other side of the trolley body 1 , and the arc track 21 is mounted on the trolley body 1 .

[0065] The carrying trolley 22 is disposed on the arc track 21 , and the carrying trolley 22 moves back and forth on the arc track 21 by being pulled by a chain or a steel wire rope.

[0066] The paving assembly is arranged on the carrying trolley 22, and the pressing assembly is arranged on the paving assembly.

[0067] The paving assembly includes a truss 23 and a rotating shaft 24. The truss 23 is connected to the carrying trolley 22. At the same time, a rotating shaft 24 is rotatably provided on the top of the truss 23. The two ends of the rotating shaft 24 are respectively rotatably connected to the two ends of the truss 23.

During the movement of the carrying trolley 22, all the pressing wheels 25 press the unrolled waterproof sheet on the top of the tunnel.

[0070] Repeat this cycle to complete the installation of the waterproof board.

[0071] In another specific embodiment:

[0072] The annular steel bar conveying mechanism 3 comprises a first conveying assembly 31, a first conduit 32, a guide wheel 33, a second conduit 34 and a second conveying assembly 35. Specifically, the first conveying assembly 31 is installed on one side of the trolley body 1, and the input part and the output part of the first conveying assembly 31 are respectively oriented towards the two ends of the trolley body 1.

[0073] A motor and a driving wheel are disposed inside the first conveying assembly 31 . The motor drives the two driving wheels to rotate simultaneously, so that the annular steel bars pass through between the two driving wheels, thereby enabling the annular steel bars to obtain the power for movement.

[0074] The structure of the second conveying assembly 35 is the same as that of the first conveying assembly 31 . The second conveying assembly 35 is installed on the side of one end of the trolley body 1 , and the input part and the output part of the second conveying assembly 35 are distributed on the longitudinal plane.

The axes of all guide wheels 33 are parallel to each other and arranged in the horizontal direction, and are distributed in pairs at the same position, and there is a gap between the two guide wheels 33 in each pair for the annular steel bars to pass through.

[0077] During the construction process, one end of the annular steel bar is sent into the first conveying assembly 31 from the end of the bell-mouth of the second conduit 34. Under the action of the first conveying assembly 31 and the first conduit 32, the annular steel bar smoothly reaches the second conveying assembly 35. The second conveying assembly 35 relays the annular steel bar so that the annular steel bar is embedded in each pair of guide wheels 33, thereby transporting the annular steel bar to the trolley body 1. When the workers are working, they only need to transport the annular steel bar to the appropriate spacing position and tie it to the top of the tunnel.

[0078] In another specific embodiment:

The hand wheel 43 is connected to the support rod 42 by power, and the support rod 42 can be driven to move in the vertical direction by rotating the hand wheel 43.

[0080] The longitudinal steel bar temporary storage component 44 is disposed on the carrying trolley 22 , and the longitudinal steel bar temporary storage component 44 has at least one strip-shaped temporary storage portion for placing the longitudinal steel bars.

[0081] During the construction process, workers place the longitudinal steel bars inside the longitudinal steel bar temporary storage assembly 44, and the carrying trolley 22 moves according to the spacing of the longitudinal steel bars. Each time the longitudinal steel bars are in place, the workers take out the longitudinal steel bars and tie them up until the tying of the annular steel bars of the entire second lining is completed.

[0082] After the longitudinal steel bars are transported to the trolley body 1 by the carrying trolley 22, they are stored in the longitudinal steel bar temporary storage assembly 44. The workers move to a suitable position, and then use the support rods 42 to lift the longitudinal steel bars and support them on the top of the tunnel to facilitate the workers' binding construction.

[0083] Preferably, the axis of the handwheel 43 is arranged on the support frame 41 in the horizontal direction, a worm gear is provided on one end of the handwheel 43 located in the support frame 41, and the bottom end of the support rod 42 is a worm structure. The engagement of the worm gear and the worm can achieve the purpose of driving the support rod 42 to move up and down when the handwheel 43 rotates.

[0084] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
