[0021] See also Figure 1-5 As shown, a front fulcrum hanging basket of a cable-stayed bridge comprises a moving track 1, which is used to determine the moving distance and position of the top parts. Both sides of the top of the moving track 1 are slidably connected with a moving seat 2, and the moving seat 2 is used in conjunction with the moving track 1. A diamond frame 3 is installed on the top of the moving seat 2, and a mounting shell 4 is fixedly connected to the top of the inner wall of the moving seat 2. The bottom of the mounting shell 4 is slidably connected to the inner wall of the moving track 1. A hydraulic cylinder 5 is installed on one side of the mounting shell 4, and the hydraulic cylinder 5 is used to provide power for movement. The output shaft of the hydraulic cylinder 5 passes through the mounting shell 4 and is fixedly connected to a connecting bracket 6. Both sides of the connecting bracket 6 are fixedly connected with connecting rods 7. Both sides of the inside of the mounting shell 4 are provided with limiting mechanisms 8, and the limiting mechanisms 8 are used to determine the position of the moving seat 2 and its top parts to avoid the moving seat 2 and the diamond frame 3 being moved during work. The position of the frame 3 changes, and the position of the limit mechanism 8 components is changed by the hydraulic cylinder 5, so the state of the moving seat 2 can be changed, and it can be adjusted according to work needs. Both sides of the inner wall of the moving track 1 are fixedly connected with fixed rods 9, and the fixed rods 9 are used in conjunction with the limit mechanism 8. Both sides of the moving seat 2 are slidably connected with mounting plates 10, and the mounting plate 10 is L-shaped. A connecting plate 11 is fixedly connected to one side of the mounting plate 10, and a guide mechanism 12 is provided on one side of the mounting plate 10. The guide mechanism 12 is used to guide the mounting plate 10 and the parts on one side thereof when they move, so as to improve the stability of the parts on one side when they move, and improve the positioning effect. A positioning mechanism 13 is provided on the other side of the mounting plate 10, and the positioning mechanism 13 is used to position the device during work, so as to facilitate the staff to punch holes and fix the bridge deck, and improve convenience.

[0022] The limiting mechanism 8 includes a limiting rod 81 that passes through both sides of the mounting shell 4, the limiting rod 81 is slidably connected to the inner wall of the mounting shell 4, and compression springs 82 are fixedly connected to both sides of the mounting shell 4. One end of the compression spring 82 is fixedly connected to the limiting rod 81, and one end of the limiting rod 81 located inside the mounting shell 4 is fixedly connected to a moving block 83, and the moving block 83 is slidably connected to the inner wall of the mounting shell 4. A sliding groove 84 is provided on the surface of the moving block 83, and the sliding groove 84 is inclined to the outside, and the sliding grooves 84 on both sides are mirrored. The connecting rod 7 is slidably connected to the inner wall of the sliding groove 84, and a limiting groove 85 is provided on one side of the fixed rod 9. The limiting rod 81 and the limiting groove 85 The inner wall is slidably connected, and the limit groove 85 is used in conjunction with the limit rod 81. The hydraulic cylinder 5 pulls the connecting bracket 6 to control the connecting rod 7 to slide inside the slide groove 84, thereby driving the moving block 83 to push the limit rod 81 to one side, so that one end of the limit rod 81 is embedded in the interior of the slide groove 84, and the moving seat 2 and the diamond frame 3 on the top of the moving seat 2 are limited and fixed to avoid the position of the diamond frame 3 changing during the bridge construction process. Similarly, the hydraulic cylinder 5 pushes the connecting bracket 6 to control the limit rod 81 to disengage from the interior of the slide groove 84, release the limit on the moving seat 2, and move the position of the diamond frame 3, which is convenient for the position of the mobile device at the bridge construction node and improves the fixing effect.

[0023] The guide mechanism 12 includes a guide block 121 fixed on both sides of the moving seat 2. A guide groove 122 is opened on one side of the mounting plate 10. The guide block 121 is slidably connected to the inner wall of the guide groove 122. When the moving track 1 is installed on the bridge deck, the staff controls the guide block 121 to slide inside the guide groove 122 by pushing and pulling the connecting plate 11, thereby controlling the positioning mechanism 13 to locate the punching position, which is convenient for the staff to punch holes.

[0024] The positioning mechanism 13 includes an electric telescopic rod 131 installed on the top of the mounting plate 10, and the bottom of the output shaft of the electric telescopic rod 131 is fixedly connected with a positioning plate 132, and the positioning plate 132 is slidably connected to the mounting plate 10.

The number of the positioning rods 134 and the positioning groove 133 are the same, and the positions correspond to each other. The position where the pit needs to be dug is determined by moving the mounting plate 10, which is convenient for subsequent positioning of the device. Then, the staff digs the pit on the bridge deck through the positioning groove 133. After the pit is dug, the mounting plate 10 is moved again to make the position of the positioning rod 134 correspond to the position of the pit on the bridge deck, and then the positioning plate 132 and the positioning rod 134 are driven by the electric telescopic rod 131 to descend to the inside of the positioning pit, so as to position the device. The operation is simple, manpower is saved, and the staff can locate the pit conveniently while reducing the labor intensity of the staff.

Similarly, the hydraulic cylinder 5 pushes the connecting bracket 6 to control the limiting rod 81 to disengage from the inside of the slide groove 84, releasing the limit on the moving seat 2 Position, convenient for moving the device, then install the diamond frame 3 on the ground site, then hoist the diamond frame 3 on the top of the mobile seat 2, and then move the mounting plate 10 to determine the position where the pit needs to be dug. After positioning, the staff will dig a pit on the beam body through the positioning groove 133. After the pit is dug, move the mounting plate 10 again, and make the position of the positioning rod 134 correspond to the position of the pit on the bridge deck. Then, the positioning plate 132 and the positioning rod 134 are driven by the electric telescopic rod 131 to descend to the inside of the positioning pit, so as to position the device, facilitate anchoring of the load-bearing frame of the hanging basket, and then assemble the other components of the hanging basket.
