DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] As Figure 1 shown, in the embodiment of the present application, an emergency steering wheel structure for a hangar door includes a guide wheel 1, a motor drive wheel set, a driven meshing runner 12, and a cam wrench and connecting rod assembly. Among them, the guide wheel 1 is arranged at the bottom of the hangar door leaf. The motor drive wheel set includes a motor 6 and a sprocket chain assembly. Among them, the input end of the sprocket chain assembly is connected to the output shaft of the motor 6, and the output end of the sprocket chain assembly is connected to the guide wheel 1. The driven meshing runner 12 is installed on the rotating shaft of the motor 6. The manual steering wheel assembly includes a steering wheel 9, a speed reducer 10, and a driving meshing runner 11. The steering wheel 9 is connected to the input shaft of the speed reducer 10 through a steering wheel shaft, and the output end of the speed reducer 10 is fixedly connected to the driving meshing runner 11. The cam wrench and connecting rod assembly includes a cam wrench 8, a connecting rod 7, and a wrench locking rod 13. The cam wrench 8 is connected to the wrench locking rod 13 through the connecting rod 7. The wrench locking rod 13 is connected to the driven meshing runner 12. When the cam wrench 8 is pulled, the wrench locking rod 13 is driven by the connecting rod 7 to tilt towards the driving meshing runner, so that the driven meshing runner 12 extends towards the driving meshing runner and meshes with the driving meshing runner 11.

[0022] As Figure 1 shown, in the embodiment of the present application, the guide wheel 1 is installed on the drive frame 14, and the drive frame 14 is connected to the door leaf (not shown in the figure).

[0023] When a power system failure occurs and the push-pull type hangar door cannot be opened and closed by the motor 6, at this time, the hangar door can be opened and closed through the emergency steering wheel structure of the hangar door. The specific operation is as follows:

[0024] First, rotate the cam wrench 8 to make the driven meshing runner 12 extend towards the driving meshing runner 11 and mesh with the driving meshing runner 11. Then manually rotate the steering wheel 9. When the steering wheel 9 rotates, it will drive the gears in the speed reducer 10 to rotate through the steering wheel shaft, thereby driving the driving meshing runner 11 to rotate. When the driving meshing runner 11 rotates, it will drive the driven meshing runner 12 to rotate, and the motor 6 is driven to rotate through the driven meshing runner 12. The motor 6 then drives the steering wheel to rotate through the sprocket chain assembly, thereby realizing the pushing and pulling action of the door leaf. Since a speed reducer 10 is provided in the emergency steering wheel structure of the hangar door, the push-pull type hangar door can be opened and closed with a relatively small force.

[0025] As Figure 1As shown, in a possible embodiment, a protective collar (not shown in the figure) that does not rotate with it is installed on the outer side of the driven meshing runner 12, and the protective collar is connected to the wrench lock rod 13. Installing a protective collar that does not rotate with it on the outer side of the driven meshing runner 12 can effectively prevent external objects from colliding with and damaging the driven meshing runner 12, improving the safety and service life of the equipment. Connecting the protective collar to the wrench lock rod 13 increases the structural stability, enabling the driven meshing runner 12 to mesh more accurately with the driving meshing runner 11 during emergency operations and improving the reliability of emergency operations.

[0026] As Figure 1 shown, in a possible embodiment, the sprocket chain assembly includes a first sprocket 5, a first chain 4, a second sprocket 3, and a second chain 2; the first sprocket 5 is connected to the output shaft of the motor 6; the first sprocket 5 and the second sprocket 3 are connected by the first chain 4; the second sprocket 3 and the guide wheel 1 are connected by the second chain 2. Using the sprocket chain assembly composed of the first sprocket 5, the first chain 4, the second sprocket 3, and the second chain 2 realizes the efficient transmission of the power of the motor 6 to the guide wheel 1, reduces power loss, and improves the operating efficiency of the system. The design of the sprocket chain assembly makes the entire transmission system more flexible, capable of adapting to different working environments and load conditions, and enhancing the adaptability and stability of the system.

[0027] As Figure 2 shown, in the embodiment of the present application, threads are provided on the connecting rod 7. When the cam wrench 8 is turned clockwise to mesh the driven meshing runner 12 with the driving meshing runner 11, through the cooperation of the nut 16 and the threads on the connecting rod 7, the driven meshing runner 12 is kept in the meshing state with the driving meshing runner 11. When the driven meshing runner 12 and the driving meshing runner 11 need to be separated, the nut 16 can be loosened. Since a return spring 17 is sleeved on the connecting rod 7, when the nut 16 is loosened, under the action of the return spring 17, the driven meshing runner 12 returns to its original position and separates from the driving meshing runner 11.

[0028] As Figure 1 shown, in a possible embodiment, the cam wrench 8 is hingedly installed on the reducer mounting seat 15.

[0029] In the embodiment of the present application, a push-pull type hangar door adopts the hangar door emergency steering wheel structure as described in the embodiment of the present application.

[0030] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
