Detailed implementation mode

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] A connecting structure of a boarding bridge lifting mechanism is used to connect the lifting mechanism with the boarding bridge main body 1, as Figures 1-7 shown, including a first connecting plate 9 and a second connecting plate 11. The lifting mechanism includes a base 3. Two oil cylinders 4 are fixedly installed on the upper surface of the base 3. U-shaped brackets 2 are fixedly connected to both ends of the outer wall of the boarding bridge main body 1. The first connecting plate 9 is fixedly installed on the bottom surface of the U-shaped bracket 2. The second connecting plate 11 is arranged below the first connecting plate 9. The bottom surface of the second connecting plate 11 is fixedly connected with an outer shell 10. The outer shell 10 is fixedly connected with the oil cylinder 4. Two fixing plates 26 are fixedly connected to both outer side walls of the U-shaped bracket 2. Short rods are rotatably connected to the outer side walls of the two fixing plates 26. A support rod 8 is fixedly connected between the two short rods. An auxiliary mechanism is arranged inside the outer shell 10.

[0032] The auxiliary mechanism includes a mounting plate 12. The mounting plate 12 is fixedly installed inside the outer shell 10. A central gear 14 and several first transmission gears 13 are rotatably connected to the upper surface of the mounting plate 12 through a shaft rod. And several first transmission gears 13 are meshed with the central gear 14. A first motor is installed on the bottom surface of the mounting plate 12. And the output end of the first motor is connected to the central gear 14 through a shaft rod. Connecting rods 29 are fixedly connected to the upper surfaces of several first transmission gears 13. Insert rods 15 are inserted into several connecting rods 29.

[0033] The inner wall of the connecting rod 29 is provided with two limiting vertical grooves. Limiting sliders 23 are inserted into both of the two limiting vertical grooves, and one end of each of the two limiting sliders 23 is fixedly connected to the inserting rod 15. When the connecting rod 29 rotates with the first driving gear 13, limited by the limiting slider 23 and the limiting vertical groove, the inserting rod 15 can rotate simultaneously, and the inserting rod 15 can slide along the inside of the connecting rod 29. The limiting slider 23 slides along the limiting vertical groove following the inserting rod 15.

[0034] Bolts 16 are fixedly connected to the upper ends of a plurality of inserting rods 15. A plurality of round holes are penetratingly opened on the upper surface of the second connecting plate 11. A plurality of screw holes 17 are opened on the bottom surface of the first connecting plate 9, and the screw holes 17 cooperate with the bolts 16. A first thread is opened on the inner wall of the screw hole 17, and a second thread is opened on the outer wall of the bolt 16. The first thread and the second thread cooperate with each other.

[0035] During use, when connecting the boarding bridge main body 1 and the lifting mechanism, first place the first connecting plate 9 and the second connecting plate 11 closely. At this time, each bolt 16 passes through each round hole and is inserted into the screw hole 17, and is located at a position close to the bottom end inside the screw hole 17. Then, the first motor installed on the bottom surface of the mounting plate 12 drives the central gear 14 to rotate, thereby driving each first driving gear 13 to rotate. Each second connecting plate 11 rotates following the first driving gear 13, thereby driving the inserting rod 15 and the bolt 16 to rotate. Under the cooperation of the first thread of the screw hole 17 and the second thread on the outer wall of the bolt 16, the bolt 16 can rotate and be inserted into the screw hole 17 to connect and fix the second connecting plate 11 and the first connecting plate 9, thereby realizing the operation of automatically connecting the upper end of the oil cylinder 4 to the bottom surface of the U-shaped bracket 2, and conveniently and automatically completing the connection of the boarding bridge main body 1 and the lifting mechanism.

[0036] Driving gears two 18 are fixedly connected to one ends of two short shafts. A rack 20 is meshed with one side of each of the two driving gears two 18. A telescopic connecting rod 19 is fixedly connected to the upper end of the rack 20, and the upper end of the telescopic connecting rod 19 is fixedly connected to the boarding bridge main body 1. A support spring is sleeved outside the telescopic connecting rod 19. Vertical plates 28 are fixedly installed on the outer side wall and the bottom surface of the boarding bridge main body 1. Motors two are installed on the outer side walls of the two vertical plates 28, and the output ends of the two motors two are respectively connected to the two driving gears two 18. By driving the driving gears two 18 to rotate through the motors two, the short shafts are driven to rotate, thereby driving the support rod 8 to rotate, so that the support rod 8 in the initial vertical state rotates to a certain angle.

[0037] Two cross bars 25 are fixedly connected to the outer side wall of the U-shaped bracket 2. U-shaped plates 24 are sleeved outside both of the two cross bars 25. Two triangular blocks 21 are fixedly connected to the bottom surface of the U-shaped plate 24, and the triangular blocks 21 are slidably connected to the bottom end of the rack 20. Two fixing rods 22 are fixedly connected to the outer side wall of the U-shaped plate 24. A jack is formed on the outer side wall of the bolt 16, and the jack is fitted with the fixing rod 22. A return spring is sleeved on the cross bar 25 at a position between the U-shaped bracket 2 and the U-shaped plate 24. One end of the support rod 8 is rotatably connected to a connecting block 7 through a shaft rod. An electric telescopic rod 6 is installed on the bottom surface of the connecting block 7. The bottom end of the electric telescopic rod 6 is fixedly connected to a support plate 5.

[0038] Specifically, after the connection between the boarding bridge main body 1 and the lifting mechanism is completed, the motor two drives the transmission gear two 18 to rotate, drives the short shaft to rotate, and thus drives the support rod 8 to rotate, so that the support rod 8 in the initial vertical state rotates to a certain angle. During this process, the transmission gear two 18 simultaneously drives the rack 20 to move downward, drives the triangular block 21 to translate toward the direction close to the connecting plate two 11, drives the U-shaped plate 24 to translate along the cross bar 25 toward the direction close to the U-shaped bracket 2 at the same time, and the return spring is compressed, thereby driving one end of the fixing rod 22 to insert into the jack, further fixing the bolt 16, and thus effectively improving the connection stability.

[0039] Finally, the electric telescopic rod 6 installed on the bottom surface of the connecting block 7 drives the support plate 5 to move downward, so that the support plate 5 moves downward until the bottom surface is closely attached to the bottom surface. Cooperating with the support rod 8, the position of the U-shaped bracket 2 can be supported, further improving the support stability of the boarding bridge main body 1.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
