Description

Technical Field

[0001] This utility model relates to the field of cable auxiliary equipment technology, and in particular to a boarding bridge cable retraction device. Background Technology

[0002] Boarding bridges are retractable and rotatable passageways installed between airport terminals and aircraft. They connect the terminal departure and arrival halls with the aircraft doors, providing passengers with a safe and convenient passageway unaffected by weather. Their function is to replace traditional boarding stairs and shuttle buses, allowing passengers to walk directly from the terminal to the aircraft and back without being exposed to the outdoors, thus improving boarding efficiency and passenger experience.

[0003] The cable retraction device of the boarding bridge is a mechanical device installed inside the boarding bridge to automatically retract and release various cables connecting the terminal building and the boarding bridge. Its function is to synchronously and orderly retract and release the cables on the boarding bridge to ensure the normal operation of the power supply, signal transmission and control system of the boarding bridge. However, in the existing boarding bridge cable retraction devices, the boarding bridge shakes and deviates, and the installation position of the retraction device is limited by the structure, which causes the cable to deviate and entangle during retraction, especially when the boarding bridge is at its limit of extension and retraction length. The braking system of the retraction device reacts slowly, and the cable continues to retract and release due to inertia, which can lead to safety accidents. Utility Model Content

[0030] 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.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a boarding bridge cable retraction device, comprising a fixed frame 1, a retraction mechanism 2 fixedly connected to one side of the outer wall of the fixed frame 1 for cable retraction, and a fixed mechanism 3 rotatably connected to the top of the outer wall of the retraction mechanism 2 for fixing the connecting device; the retraction mechanism 2 includes a support frame 201 rotatably connected to one side of the outer wall of the fixed frame 1, and a fixed shaft 202 rotatably connected to the top of the inner wall of the support frame 201; springs 204 are fixedly connected to the left and right ends of the outer wall of the fixed shaft 202, and the outer sides of the two springs 204 are... Support plates 203 are rotatably connected to both the front and rear sides of the wall. A connecting plate 205 is fixedly connected to the top of the outer wall of the support frame 201. A drive assembly 206 is fixedly connected to one side of the outer wall of the fixed frame 1. The drive assembly 206 includes a motor 2061. The motor 2061 is fixedly connected to one side of the outer wall of the fixed frame 1. A cable 2062 is fixedly connected to the output end of the motor 2061. The other end of the cable 2062 passes through the middle of the inner wall of the connecting plate 205. A guide wheel 2063 is rotatably connected to the top of the outer wall of the connecting plate 205. An auxiliary wheel 2064 is rotatably connected to the bottom of the inner wall of the connecting plate 205.

[0032] Specifically, when cable winding and unwinding operations are required, the motor 2061 of the drive assembly 206 starts, and its output end drives the cable 2062 to move. The other end of the cable 2062 passes through the middle of the inner wall of the connecting plate 205. Under the guidance and assistance of the guide wheel 2063 and the auxiliary wheel 2064, the connecting plate 205 is pulled, which drives the support frame 201 fixed thereto to rotate around the fixed frame 1. At this time, the spring 204 on the outer wall of the fixed shaft 202 in the winding mechanism 2 deforms with the rotation of the support frame 201. The support plate 203, which is rotatably connected to the front and rear sides of the spring 204, supports and cooperates with the deformation of the spring 204 to ensure that the cable is wound and unwinded in an orderly manner under the action of the fixed shaft 202, the spring 204 and the support plate 203. At the same time, the fixing mechanism 3 fixes the whole when the device is working to ensure operational stability.

[0033] Reference Figure 1 , Figure 2 and Figure 5The fixing mechanism 3 includes a fixing plate 301, which is rotatably connected to the top of the outer wall of the support frame 201. A support shaft 302 is fixedly connected to the front and rear sides of the inner wall of the fixing plate 301. An adjusting plate 304 is rotatably connected to one side of the outer wall of the support shaft 302. A gear 305 is rotatably connected to the other side of the support shaft 302. A gear 306 is fixedly connected to the left and right sides of the bottom of the fixing plate 301. The gear 306 meshes with the gear 305. The bottom of the outer wall of the gear 305... Adjustment plate 303 is fixedly connected to both the first and second adjustment plates 304. Adjustment assembly 307 is fixedly connected to the top of the outer wall of the fixed plate 301. Adjustment assembly 307 includes a rotating shaft 3071, which is rotatably connected to the top side of the fixed plate 301. A threaded rod 3072 is threadedly connected to the middle of the inner wall of the rotating shaft 3071. The threaded rod 3072 is rotatably connected to the other side of the fixed plate 301. Connecting brackets 3073 are slidably connected to the bottom of the outer walls of the first adjustment plate 303 and the second adjustment plate 304.

[0034] Specifically, when the boarding bridge cable retraction device is working, the fixing mechanism 3 is fixed synchronously, and the rotating shaft 3071 of the adjusting component 307 rotates. Because it is threadedly connected to the threaded rod 3072, it drives the threaded rod 3072 to move on the fixing plate 301. In turn, it drives the adjusting plate 1 303 and the adjusting plate 2 304 to move through the connecting frame 3073. The adjusting plate 2 304 rotates around the support shaft 302, which drives the coaxial gear 1 305 to rotate. The gear 1 305 meshes with the gear 2 306 at the bottom of the fixing plate 301. The adjustment plate 303 is rotated to adjust the angle. The adjustment plate 303 and the adjustment plate 304 cooperate with each other and are connected to the external structure through the connecting frame 3073 to fix the whole device and ensure the stability of cable winding and unwinding. The driving and transmission process of cable winding and unwinding is as before. The motor 2061 drives the cable 2062, which is guided and pulled by the guide wheel 2063 and the auxiliary wheel 2064 to pull the connecting plate 205, which drives the support frame 201 to rotate. The spring 204 and the support plate 203 cooperate with the fixed shaft 202 to complete the orderly winding and unwinding of the cable.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The bottom side of the support frame 201 is threaded with a screw 4. The top left and right sides of the connecting plate 205 are fixedly connected with a fixing shell 5. The outer wall of the connecting frame 3073 is rotatably connected with a bolt 6. The other side of the bolt 6 is threadedly connected with a partition plate 7. The top left and right sides of the fixing plate 301 are fixedly connected with a positioning plate 8. The inner wall of the positioning plate 8 has multiple connecting holes 9. The bottom front and rear sides of the motor 2061 are fixedly connected with support legs 10. The outer wall of the cable 2062 is provided with a gasket 11 on the side away from the other side.

[0036] Specifically, the support frame 201 is securely connected to other structures via screws 4 on one side of its bottom, providing reliable support for the entire collection mechanism 2 and ensuring it does not shake during operation. The fixing shells 5 on the top left and right sides of the connecting plate 205 protect and fix related components, maintaining the relative position stability of each part on the connecting plate 205. When adjustment or fixing is required, the bolts 6 rotatably connected to the outer wall of the connecting frame 3073 come into play. By rotating the bolts 6, the position of the threaded partition 7 can be adjusted to adapt to different working requirements and achieve the separation or limitation of related components. The top left and right positioning plates 8 have multiple connection holes 9, which are convenient for flexible fixing according to the actual installation scenario. The motor 2061 serves as the drive source, and the support legs 10 on the front and rear sides of its bottom enable it to be placed stably, ensuring the stability during operation. During the collection process, the motor 2061 starts and drives the cable 2062 to operate. The pad 11 on the outer wall of the cable 2062 away from the other side can reduce the friction between the cable 2062 and other components, protect the cable 2062 and improve its service life. At the same time, the guide wheel 2063 and the auxiliary wheel 2064 guide the movement direction of the cable 2062 to ensure the accurate collection action.

[0037] Working principle: When cable winding and unwinding operations are required, the motor 2061 in the drive assembly 206 starts, and its output end drives the cable 2062 to move. The other end of the cable 2062 passes through the middle of the inner wall of the connecting plate 205. Under the guidance and assistance of the guide wheel 2063 and the auxiliary wheel 2064, the connecting plate 205 is pulled, which in turn drives the support frame 201 fixedly connected to it to rotate around the fixed frame 1. At this time, the spring 204 on the outer wall of the fixed shaft 202 in the winding mechanism 2 will deform with the rotation of the support frame 201. The support plate 203, which is rotatably connected to the front and rear sides of the spring 204, plays the role of supporting and cooperating with the deformation of the spring 204, ensuring that the cable can be wound and unwound in an orderly manner under the joint action of the fixed shaft 202, the spring 204 and the support plate 203 during the rotation of the support frame 201. At the same time, the fixing mechanism 3 can fix the whole when the device is working, ensuring the stability of the operation.

[0038] When the entire boarding bridge cable retraction device is working, the fixing mechanism 3 plays a fixing role simultaneously. The rotating shaft 3071 in the adjusting component 307 rotates, and because it is threadedly connected to the threaded rod 3072, it will drive the threaded rod 3072 to move on the fixing plate 301. In turn, it will drive the adjusting plate 1 303 and adjusting plate 2 304 to move through the connecting frame 3073. When the adjusting plate 2 304 rotates around the support shaft 302, it will drive the gear 1 305 coaxial with it to rotate. The gear 1 305 meshes with the gear 2 306 at the bottom of the fixing plate 301, so that the adjusting plate 1 303 rotates and adjusts the angle accordingly. Finally, through the cooperation of the adjusting plate 1 303 and the adjusting plate 2 304, the connecting frame 3073 is used to achieve a stable connection with the external structure, thereby fixing the entire device.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
