[0020] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0021] like Figure 1-4 As shown, the utility model provides a bridge anti-collision wall template trolley, including a walking mechanism 1, a support frame 2 arranged on the top of the walking mechanism, two parallel beams 3 installed on the top of the support frame 2 by bolts, a hanging basket mechanism 4 and a counterweight box 5 are respectively arranged at both ends of the beam 3, and a hoisting mechanism 6 is arranged on the side of the beam 3 close to the hanging basket mechanism 4. The walking mechanism 1 includes a chassis frame 11, a rainproof chassis working plate 12 installed on the top of the chassis frame 11, and a steering system 13 and a driving system 14 respectively arranged at both ends of the bottom of the chassis frame 11. The front end of the outer side of the chassis frame 11 is equipped with two front wheels 16 through a steering support 15, and the rear end of the outer side of the chassis frame 11 is equipped with two rear wheels 18 through a bridge bearing seat 17. The steering system 1 The steering wheel 130 comprises a steering motor 131 and a transmission rack 132. The output end of the steering motor 131 is connected to a steering gear 133 meshing with the transmission rack 132. Both ends of the transmission rack 132 are connected to a steering tie rod 134. One end of the steering tie rod 134 is connected to a steering shaft 136 through a steering link 135, that is, one end of the steering link 135 is hinged to the steering tie rod 134, and the other end of the steering link 135 is fixedly connected to the axial surface of the steering shaft 136. The axial surface of the steering shaft 136 is connected to the front wheel 16 through a connecting shaft, that is, one end of the connecting shaft is fixedly connected to the axial surface of the steering shaft 136, and the other end of the connecting shaft is rotatably connected to the front wheel 16. The steering shaft 136 is rotatably mounted on a steering support 15, and the two steering supports 15 are connected by a cross bar 137.

[0022] like Figure 1 and 2 As shown, the steering system 13 is arranged between the two front wheels 16 to control the rotation direction of the front wheels 16. The driving mechanism 14 is arranged between the two rear wheels 18 to drive the chassis frame 11 to move. When the steering system 13 is working, the steering gear 133 on the steering motor 131 drives the transmission rack 132 to move. When the transmission rack 132 moves, the steering shaft 136 is rotated through the steering rod 134 and the steering connecting rod 135. The steering shaft 136 drives the front wheels 16 to rotate to realize the steering of the front wheels 16. The steering system adopted in the utility model is not only flexible in steering, but also can prevent rain from falling on the steering motor 131 and damaging it by arranging the steering motor 131 at the bottom and covering it with the rainproof chassis working plate 12.

[0023] The hanging basket mechanism 4 includes a hanging basket 41, and ladders 42 are hinged on the left and right ends of the upper surface of the hanging basket 41. A limit rod is installed on the top of the ladder 42, which can be used to limit the extreme position of the ladder's downward slide to ensure safety and reliability during use. The ladder 42 is slidably connected to the beam 3 through a slide seat. The slide seat includes two pulley fixing frames 43 and four pulleys 44 arranged in a rectangular shape between the two pulley fixing frames 43. The pulley fixing frame 43 near one end of the beam 3 is installed on the beam 3 by bolts. The ladder 42 is vertically arranged between the four pulleys 44 and is located in the wheel groove of the pulley 44. A hand winch 45 is installed on the beam 3, and the chain of the hand winch 45 is connected to the hanging basket 41.

[0024] like Figure 4 As shown, four pulleys 44 are rotatably installed between two pulley fixing frames 43, and the ladder 42 slides between the four pulleys 44, so that the ladder 42 can only slide up and down in the vertical direction between the four pulleys 44, and cannot move laterally or longitudinally, thereby preventing the hanging basket 41 from shaking during the construction process, thereby improving the stability of the hanging basket 41 during construction operations, and the ladder 42 is smoother and will not get stuck during the lifting and lowering process under the action of the hand winch 45.

[0025] The driving system 14 includes a rotating shaft 141, both ends of which are rotatably mounted on the bridge bearing seat 17 and connected to the rear wheel 18 through the bridge bearing seat 17. Two transmission gears 142 are installed on the rotating shaft 141. Two driving motors 143 that respectively drive the transmission gears 142 to rotate are provided at the bottom of the chassis frame 11. The output end of the driving motor 143 is connected to a driving gear 144 that meshes with the transmission gear 142.

[0026] like Figure 2 As shown, the utility model drives the rotating shaft 141 to rotate by two driving motors 143 to ensure the driving power of the rear wheel 18. When in use, the driving motor 143 drives the transmission gear 142 to rotate, and the transmission gear 142 drives the rear wheels 18 at both ends of the rotating shaft 141 to rotate, thereby realizing the operation of the walking mechanism 1.

[0027] In this embodiment, the steering system 13 and the driving system 14 are both operated by wireless remote control, and the electric hoist 62 and the motor 64 are also operated by wireless remote control, which can effectively improve the flexibility of use of the utility model.

[0028] The hoisting mechanism 6 includes a walking beam 61 and an electric hoist 62. The walking beam 61 is installed between two cross beams 3 by bolts. The lower part of both ends of the walking beam 61 and the electric hoist 62 travel on the cross beam 3 and the walking beam 61 respectively through a trolley 63. The trolley 63 is driven by a motor 64. The tops of the trolley 63 and the electric hoist 62 are connected with rain shields 65 by bolts.

[0029] like Figure 1As shown, the electric hoist 62 is used to hoist the anti-collision wall formwork. The electric hoist 62 can be moved longitudinally on the walking beam 61 through the walking beam 61. The trolley 63 under the two ends of the walking beam 61 travels on the crossbeam 3, which can make the electric hoist 62 move laterally on the crossbeam 3, so as to facilitate the adjustment of the position of the anti-collision wall formwork and the disassembly of the formwork; the rain shield 65 can prevent the motor 64 and the electric hoist 62 from being exposed to the outside, and they are easily damaged by rain in thunderstorm weather, which affects their service life.

[0030] A variable frequency starting electrical box 7 is installed at one end of the top of the rainproof chassis working plate 12 , and the output end of the variable frequency starting electrical box 7 is electrically connected to the input end of the driving motor 143 .

[0031] like Figure 1 As shown, the variable frequency starting electrical box 7 can control the driving motor 143 to start slowly, reduce the current impact during starting, reduce the impact on the transmission gear 142, and extend the service life.

[0032] A canopy 8 is mounted on the top of the crossbeam 3 via a mounting frame and bolts.

[0033] like Figure 1 As shown, the canopy 8 can prevent the items on the rain tray working plate 12 from being exposed to the outside and being eroded by rainwater during thunderstorms.

[0034] The support frame 2 includes columns 21 installed at four corners of the top of the rainproof chassis working plate, and two adjacent columns 21 are connected by reinforcing ribs 22.

[0035] like Figure 3 As shown, the support frame 2 includes columns installed at the four corners of the top of the rainproof chassis working plate 12. Compared with the traditional two-column support frame, the present invention has higher stability; in this embodiment, the depth of the hanging basket is deepened to ensure the safety of the construction workers.

[0036] Principle of use: When in use, the chassis frame 11 is moved to the place where it is needed by controlling the driving motor 143. When steering is required during the movement, the steering motor 131 can be controlled to rotate forward or reverse. When the steering motor 131 rotates forward or reverse, it drives the transmission rack 132 to move to one side of the chassis frame 11, and the transmission rack 132 prompts the steering rod 134 and the steering connecting rod 135 to move in the same direction. The steering connecting rod 135 drives the steering shaft 136 to rotate in the same direction, and the steering shaft 136 drives the two front wheels 16 to steer in the same direction; the hanging basket 41 is lifted and lowered along the slide by manually pulling the hand winch 45. During the lifting process, the ladder 42 slides between the four pulleys 44, so that the ladder 42 can only slide up and down in the vertical direction between the four pulleys 44, and cannot move horizontally or longitudinally, so as to avoid the hanging basket from shaking during the construction process, thereby improving the stability of the hanging basket 41 during construction operations, and the ladder 42 is smoother and will not get stuck during the lifting process.

[0037] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
