    [0004] FIELD OF THE INVENTION
    [0005]
    [0006] The present invention relates to a canopy boarding gangway powered by a highly integrated, self-locking canopy drive mechanism.
    [0007]
    [0008] BACKGROUND OF THE INVENTION
    [0009]
    [0010] The boarding gangway canopy is a part where a forward end of the boarding gangway interacts with an airplane door. The canopy revolves around a control room located between the canopy and the rest of the boarding bridge. In the prior art, the boarding gangway canopy is driven to rotate around the control room by a reduction motor through the sprocket or chain drive, which constitutes a drive chain. With the interaction of the canopy with an airplane door the engine can receive a certain force of inertia by impact, causing a failure of a certain link in the transmission chain, which will carry potential safety risks for the airplane and passengers , such as, for example, breakage of the chain, detachment of the sprocket and breakage of the shaft of the rotary motor, etc., during the operation of said transmission chain.
    [0011]
    [0012] In order to prevent the canopy from having an uncontrolled movement when a mechanical system failure occurs in the canopy, an improvement is proposed for the boarding bridge both inside and outside the country. In view of this, the invention provides a highly integrated self-locking drive mechanism for canopy and a boarding gangway that applies it, in order to solve the above technical problem.
    [0013]
    [0014] SUMMARY OF THE INVENTION
    [0015]
    [0016] In order to solve the above technical problems, the invention provides a boarding gangway that includes a canopy arranged at a forward end of the boarding bridge. Said canopy can rotate relative to the rest of the boarding walkway around a center driven by means of a highly integrated self-locking drive mechanism for canopy.
    [0017]
    [0018] The invention adopts the following technical solutions to solve its technical problems:
    [0019]
    [0020] The highly integrated self-locking canopy drive mechanism comprises a bracket with one end secured to the canopy and with another end pivotally connected to a lower end of the boarding walkway via a rotary drive device that drives the bracket to produce the rotation of the canopy, and also includes traction bars with one end secured to the canopy and with another end pivotally connected to an upper end of the boarding gangway.
    [0021]
    [0022] The rotary drive device comprises a worm gear driven by a motor secured to the boarding bridge and a gear ring secured to the support, said gear ring being driven by said worm screw, constituting as a whole a self-locking mechanism.
    [0023]
    [0024] The rotary drive device may further comprise a support base including a first housing containing the ring gear, a second housing containing the worm gear, the first and second housings being interconnected allowing the drive of the ring gear by the worm gear, and the ring gear is connected to the support through an opening in the first housing.
    [0025]
    [0026] Said support base may further include a rotary encoder to detect the rotation of the worm screw.
    [0027]
    [0028] The worm gear can be driven by a hydraulic motor or a servo motor or a reduction motor.
    [0029]
    [0030] The support base may further comprise a protective casing and an inner bushing, in which the protective casing is cylindrical in shape, and the outer diameter of the inner bushing is smaller than the inner diameter of the protective casing, a bolt passes to Through the inner bushing and the bottom of the protective casing to connect with the boarding bridge, and a gap between the internal bushing and a side wall of the protective casing forms the first housing.

    [0032]
    [0033] The invention has the beneficial effects that a bracket and a rotary drive device are used to directly support and drive the canopy to rotate, and the pull bars serve to cause the canopy to cooperate with the boarding gangway, so that the Complete mechanism is simple and compact. The rotary drive device has a self-locking mechanism, which can lock relative movement between the canopy and the boarding gate when a failure of the rotary drive device occurs, thus avoiding uncontrolled actions after the failure of the rotary drive device. Both the rotary drive device and bracket adopt a heavy-duty structure that provides enough strength to achieve an extremely low failure rate, and cooperation between them can ensure that relative movement between the canopy and the boarding walkway is blocked immediately when a fault occurs so that it plays the protective role.

    [0051]
    [0052] DETAILED DESCRIPTION OF THE REALIZATIONS
    [0053]
    [0054] Referring to Figures 1 to 7, the invention provides a canopy boarding gangway operated by a highly integrated self-locking drive mechanism for canopy.
    [0055]
    [0056] Said drive mechanism comprises a support 3a, with one end secured to the canopy 2 and with another end pivotally connected to a lower end of the gangway 1 through a rotary drive device 5, 6, 7, 8 which actuates the support 3a to produce the rotation of the canopy 2, and several drawbars 3, with one end fastened to an upper end of the canopy 2, and with another end pivotally connected to an upper end of the gangway boarding 1 using a rotating shaft 4.
    [0057]
    [0058] The rotary drive device 5, 6, 7, 8 comprises a worm gear 5 driven by a motor secured to the boarding bridge and a ring gear 6 secured to the support 3a, said gear ring 6 being driven by said worm screw 5 constituting a self-locking mechanism.
    [0059]
    [0060] In the invention, the bracket 3a and the rotary drive device 5, 6, 7, 8 are used to directly support and drive the canopy 2 to rotate, and the draw bars 3 serve to make the canopy 2 cooperate with the gangway boarding 1, so that the entire structure is simple and compact.
    [0061]
    [0062] The rotary drive device 5, 6, 7, 8 has a self-locking mechanism, which can perform relative motion lock between canopy 2 and boarding gate 1 when a failure of the rotary drive device 5, 6, 7 occurs, 8, thus avoiding uncontrolled actions after the failure of the rotary drive device 5, 6, 7, 8.
    [0063]
    [0064] Both the rotary drive device and bracket adopt a high-strength structure that provides enough strength to achieve an extremely low failure rate, and cooperation between them can ensure that the Relative movement between canopy 2 and boarding gate 1 is immediately blocked when a fault occurs so that it plays the protective role.
    [0065]
    [0066] The complete structure of the rotary drive device is made of high strength structural steel. Therefore, the structural resistance is increased dozens of times in relation to other solutions based on sprockets and chains, and the possibility of failure is practically nil.
    [0067]
    [0068] The self-locking function of the rotary drive device can be performed by adjusting an advance angle of the worm screw 5 to be smaller than an equivalent friction angle between the ring gear teeth 6.
    [0069]
    [0070] The rotary drive device 5, 6, 7, 8 further comprises a support base 7 which includes a first housing containing the ring gear 6 and a second housing containing the worm screw 5. The first housing and the second housing are interconnected, allowing the ring gear 6 to engage the worm screw 5, and a lower end of the ring gear 6 is connected to the support 3a through an opening in the first housing.
    [0071]
    [0072] The support base 7 may further include a rotary encoder 8 which is used to detect the rotation of the worm screw 5.
    [0073]
    [0074] As shown in the figures, the worm screw 5 is driven by a hydraulic motor or a servomotor or a reduction motor 9. The angle of rotation of the worm 5 is detected by the rotary encoder 8 and the collected information is used to control the actions of the hydraulic motor or the servo motor or the gear motor 9 to achieve a goal of accurately controlling an angle adjustment of canopy twist 2.
    [0075]
    [0076] The support base 7 comprises a protective casing 10 and an internal bushing 11. The protective casing 10 is cylindrical in shape, and an external diameter of the internal bushing 11 is smaller than an internal diameter of the protective casing 10. A bolt passes into Through the inner bushing 11 and the bottom of the protective casing 10 to connect with the boarding gate 1. A space between the internal bushing 11 and a side wall of the protective casing 10 forms the first housing.
    [0077]
    [0078] A first annular groove 13 is provided in an external side wall of the internal hub 11, and a second annular groove 14 is arranged in an internal lateral wall of the ring gear 6. The first annular groove cooperates with the second annular groove to form an annular channel in which the bearings are fitted. Annular flanges 12 are arranged both on the internal hub 11 and on the side wall of the protective casing 10.
    [0079]
    [0080] The structural resistance of the rotary drive device that has the previous mechanism is very high, and is increased by dozens of times in relation to the sprockets and chains, therefore, the possibility of failure is practically nil. Even if there is a failure, there will be no relative rotation between canopy 2 and boarding gate 1 due to the presence of the self-locking function which can prevent uncontrolled movements. The specific actions of the rotary drive device with the above mechanism are as follows: the reduction motor 9 drives the rotation of the worm screw 5 that drives the ring gear 6 to rotate, then the support connected to the ring gear 6 rotates, which this in turn leads to canopy 2 to turn, thus making the turn of canopy 2 relative to boarding bridge 1.
    [0081] Referring to Figures 1 to 7, the invention also provides a boarding gangway applying the above, highly integrated, self-locking canopy drive mechanism, comprising a boarding gangway 1, a canopy 2, a walking support device and the highly integrated, self-locking drive mechanism above for canopy. The canopy 2 is installed rotatably on the boarding bridge 1 by means of the drive mechanism for the canopy, and for the specific way of connection, see the previous description. The walking support device is installed under the boarding bridge 1 to support and drive the boarding bridge 1 to move. The walking support device adopts a consolidated technique in the prior art that will not be shown in detail herein.
    [0082]
    [0083] The foregoing embodiments are only the preferred embodiments of the invention, and other embodiments may also be included in the invention. Equivalent variations or substitutions can be made by one skilled in the art without departing from the spirit of the invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of the present application.
