[0016] Figure 2 It is the front view of the driving mechanism;

[0017] Figure 3 It is a side view of the driving mechanism;

[0018] Figure 4 It is a structural diagram of the translation seat. DETAILED DESCRIPTION

[0019] like Figure 1-4 As shown, the present invention provides a tarpaulin handling vehicle, comprising a mast 1 with two lanes of space within. Oppositely disposed swivel seats are provided on either side of the mast 1's upper portion. A swivel shaft 2 is rotatably connected between the two swivel seats. Extending from the swivel seats at both ends of the swivel shaft 2 are respectively secured to support frames 3. Each support frame 3 is provided with a telescopic arm 4 (the telescopic arm utilizes a multi-section telescopic sleeve structure, enabling a wide range of telescopic movement). A crossbar 5 is secured between the top ends of the two telescopic arms 4.

[0020] A transition shaft 21 is fixed in the middle of the rotary shaft 2. The transition shaft 21 is rotatably connected to the slewing bearing in the middle of the gantry 1. The gantry 1 is connected to a driving mechanism for driving the transition shaft 21 to rotate. The driving mechanism includes two driving oil cylinders 6. The cylinder ends of the two driving oil cylinders 6 are respectively hinged to the gantry 1. The front ends of the piston rods of the two driving oil cylinders 6 are respectively fixed with traction ropes 7 (traction ropes 7 are steel wire ropes). The free ends of the two traction ropes 7 are respectively fixed to the outer wall of the transition shaft 21. The transition shaft 21 is driven to rotate through the cooperation of the two driving oil cylinders 6. Specifically, Figure 2-3 As shown, two driving cylinders 6 are located on either side of the slewing bearing. Two traction ropes 7 are looped around the transition shaft 21 in opposite directions, and the free ends of the two traction ropes 7 are fixedly riveted to the transition shaft (the two traction rope riveting points 71 are axially offset). This allows for high-load driving. During operation, one driving cylinder 6 extends while the other retracts, driving the slewing shaft 2 back and forth. When both driving cylinders 6 cease operation (hydraulic oil flow stops), the transition shaft 21 and the slewing shaft 2 are immediately stopped.

[0021] The bottom of the gantry 1 is connected to a moving wheel set, which includes two driving wheels 8 on both sides of one end of the gantry 1 and two driven wheels 9 on both sides of the other end of the gantry 1. The movement of the entire operating trolley can be achieved by the moving wheel set.

[0022] The four bottom legs of the gantry 1 are each equipped with a translation base 10, which comprises a sliding sleeve 101, a support leg 102, a lifting cylinder, a base 104, and a translation cylinder 103. The sliding sleeve 101 is vertically fixed to the bottom of the gantry 1. The support leg 102 is slidably connected to the sliding sleeve 101 and is driven up and down by the lifting cylinder. The lifting cylinder is hinged within the sliding sleeve 101. The bottom of the support leg 102 is slidably connected to the translation guide rail at the top of the base 104. The ends of the translation cylinder 103 are respectively hinged to the top of the base 104 and the lower side of the support leg 102. During operation, the support leg 102 is lowered to the base 104 for support on the tunnel floor, and the translation cylinder 103 drives the entire gantry 1 to move laterally.

[0023] The top of the gantry 1 is provided with an upper platform 11, and side platforms 12 with a stepped structure are provided on both sides of the upper platform 11. Stairs 13 leading to the side platforms 12 are provided on both sides of the gantry 1. Telescopic platforms 14 that can move horizontally are provided on both sides of the stairs 13. Workers can assist in laying and hanging waterproof cloth on the inner wall of the tunnel on the upper platform 11, the side platform 12 and the telescopic platform 14, thereby improving the laying quality and construction efficiency of the waterproof cloth. The telescopic platform 14 can be driven by the rotating cylinder 6 to telescopically slide, or it can be driven by a gear rack and a motor. By driving the telescopic platform 14 to move, workers can maintain a suitable working distance from the tunnel surface when assisting in the work. In order to ensure safety, protective railings are provided on the sides of the telescopic platform 14, the upper platform 11 and the side platform 12.

[0024] The above describes a specific embodiment of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of the present invention. For example, according to needs, the two driving cylinders 6 can also be arranged on the same side of the slewing support at the same time, one of the driving cylinders 6 extends and the other driving cylinder 6 retracts, thereby driving the slewing shaft 2 to rotate back and forth. At the same time, the slewing arm structure can also be used on engineering machinery with similar needs, but these changes and modifications fall within the scope of protection of the present invention.
