Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4This utility model provides a TBM inverted arch precast block aerial tilting device, including a main housing 1. Lifting arms 2 are provided on both the left and right sides of the main housing 1. A hydraulic cylinder 3 is located inside the main housing 1 on one side, and the other side of the hydraulic cylinder 3 is connected to the upper inner side of the lifting arm 2. A lifting beam 4 is located at the middle of the upper inner end of the main housing 1. A transmission box 5 is located at the lower end of each of the two lifting arms 2. A tilting motor 6 is located at the power input end of the transmission box 5, and a tilting seat 7 is located at the power output end of the transmission box 5. A main lifting pin 8 is located at the middle of the inner surface of each of the two tilting seats 7, and limiting pins 9 are located on the inner surface of each of the two tilting seats 7 and on both sides of the main lifting pin 8.

[0017] In use, the overall tilting device is connected to the external lifting equipment via the lifting beam 4. The lifting equipment then lifts the overall tilting device. Under the power of the hydraulic cylinder 3, the lifting arm 2 rotates around the main box 1, with the lower ends of the two lifting arms 2 moving away from each other. The lifting equipment then lowers the overall tilting device to the position of the precast block. Subsequently, under the power of the hydraulic cylinder 3, the lifting arm 2 rotates around the main box 1, with the lower ends of the two lifting arms 2 moving closer together, thus clamping the tilting seat 7 to the lower slot of the precast block. The main lifting pin 8 is inserted into the lower slot of the precast block, and the limiting pin 9 is inserted into the lower limiting groove of the precast block. The lifting equipment then lifts the precast block, and the tilting device carries it up. The tilting motor 6 then starts, and the power of the tilting motor 6 is transmitted to the tilting seat 7 through the transmission box 5, causing the tilting seat 7 to rotate, thereby tilting the overall precast block structure at an angle, which facilitates the inspection and maintenance of the precast blocks by the staff.

[0018] The lower ends of the left and right sides of the main housing 1 and the inner end of the lifting arm 2 are all provided with pivot seats 10. The lifting arm 2 is rotatably connected to the main housing 1 through the pivot seats 10 via a pivot shaft. The inner side of the main housing 1 and the inner side of the lifting arm 2 are provided with connecting seats 11 at positions corresponding to the hydraulic cylinder 3. The two ends of the hydraulic cylinder 3 are rotatably connected to the connecting seats 11 via a pivot shaft. By setting pivot seats 10 on the main housing 1 and the lifting arm 2, and by splicing the pivot shaft with the pivot seats 10, the lifting arm 2 is rotatably connected to the main housing 1. By setting connecting seats 11 on the main housing 1 and the lifting arm 2, and by splicing the pivot shaft with the connecting seats 11, the two ends of the hydraulic cylinder 3 are respectively rotatably connected to the main housing 1 and the lifting arm 2.

[0019] The two transmission boxes 5 have a rotating groove 12 at the lower inner end corresponding to the flip seat 7. The flip seat 7 is rotatably connected to the inside of the rotating groove 12. By setting the rotating groove 12 at the lower end of the transmission box 5, space is left for the rotation of the rotating seat 7.

[0020] A through groove 13 is provided on the side wall of the main housing 1 at the position corresponding to the hydraulic cylinder 3. The hydraulic cylinder 3 passes through the main housing 1 through the through groove 13. By providing a through groove 13 on the side wall of the main housing 1, the hydraulic cylinder 3 passes through the main housing 1 through the through groove 13.

[0021] A reinforcing plate 14 is provided at the middle position of the outer surface of the front and rear walls of the main box 1, corresponding to the position of the hoisting beam 4. By providing a reinforcing plate 14 on the outer surface of the main box 1, the connection strength between the hoisting beam 4 and the main box 1 is improved.
