Description

Technical Field

[0001] The utility model relates to the field of aviation equipment, and particularly relates to a manual bridge-removing auxiliary device for a boarding bridge. Background Technique

[0002] A boarding bridge is a device used to connect the waiting hall and the aircraft, extending from the boarding gate to the aircraft cabin door to facilitate passengers to enter and exit the cabin. Since the boarding bridge is the only passage for passengers to board the airliner, its safety is particularly important. In case of unpredictable risks of the boarding bridge, an emergency bridge-removing method should be adopted in time to protect the lives and property of passengers, so as to avoid extremely serious consequences.

[0003] Due to the complexity of the current bridge-removing device of the boarding bridge, the walking wheels need to work synchronously during the bridge-removing process to complete the bridge-removing activity of the boarding bridge. When one of the walking wheels in the boarding bridge fails (such as chain breakage, sprocket damage, etc.) and cannot remove the bridge by turning the crank, and the other walking wheel is running normally, since the two walking wheels are horizontally connected by a cross beam, when the normal side walking wheel moves, the boarding bridge deflects with the abnormal walking wheel as the center. In order to prevent the impact accident caused by the abnormal rotation of the boarding bridge, it is necessary to synchronize the abnormal working walking wheel with the normal walking wheel. In addition, when both walking wheels of the boarding bridge fail and cannot be driven by the motor, two people need to turn two cranks respectively to drive the two walking wheels to move synchronously for manual bridge removal. Due to the difference in the speed of manual cranking, it is very likely that the two walking wheels will move inconsistently, resulting in the deflection accident of the boarding bridge, which is likely to cause emergencies of the boarding bridge and endanger the lives and property of the public. Content of the Utility Model

[0004] The purpose of the utility model is to provide a manual bridge-removing auxiliary device for a boarding bridge. The device is connected to two walking wheels. When one of the walking wheels moves, a force opposite to the deflection direction of the boarding bridge is applied to the first operating rod to inhibit the deflection movement of the boarding bridge, so as to achieve the effect of synchronizing the abnormal walking wheel with the normal walking wheel.

[0005] The technical solution adopted by the utility model to solve the above problems is:

[0006] A manual bridge-removing auxiliary device for a boarding bridge includes a first operating rod, a connecting rod and a stress rod. The connecting rod is fixed at the rear end of the first operating rod and is perpendicular to the first operating rod. There are two stress rods, and the front ends of the two stress rods are respectively fixed at the left and right ends of the connecting rod. The stress rod is parallel to the first operating rod, and a connecting ring is provided at the rear end of the stress rod.

[0007] In the above technical solution, preferably, a reinforcing rod is provided between the first operating rod and the connecting rod. There are two reinforcing rods, and both ends of the reinforcing rods are fixedly connected to the end of the connecting rod and the first connecting rod respectively.

[0012] Compared with the prior art, the present invention has the following advantages and effects:

[0013] (1) When a failure occurs in one of the walking wheels of the boarding bridge and it is impossible to complete the bridge retraction using the crank, the two link rings are respectively connected to the traction points inside the two walking wheels by riveting. The normal walking wheels are driven by the motor to move. At this time, by applying a force to the first operating rod in the direction opposite to the deflection direction of the boarding bridge to inhibit the deflection movement of the boarding bridge, the effect of synchronous movement of the abnormal walking wheel and the normal walking wheels is achieved, thereby realizing the bridge retraction process when a certain walking wheel of the boarding bridge cannot be used to retract the bridge normally using the crank.

[0014] (2) When both walking wheels cannot be driven by the motor to move, one person shakes the crank corresponding to one of the walking wheels, and another person uses the present invention to inhibit the deflection movement of the boarding bridge through the above operation method, so as to ensure that the actions of the two walking wheels are consistent during manual bridge retraction, and reduce the occurrence of deflection accidents of the boarding bridge. Description of the Drawings

[0015] Figure 1 is a schematic diagram of the use state of the manual bridge retraction auxiliary device for the boarding bridge in the embodiment of the present invention.

[0016] Figure 2 is a disassembled schematic diagram of the manual bridge retraction auxiliary device for the boarding bridge in the embodiment of the present invention.

[0017] Among them, there are a first operating rod 1, a first external thread 11, a connecting rod 2, a stress rod 3, a connecting ring 31, a reinforcing rod 4, a second operating rod 5, a first internal thread 51, a second external thread 52, a tail rod 6, a second internal thread 61, a handle 62, a universal wheel fixing rod 7, a universal wheel 71, a jack 72, a traveling wheel 8, an abnormal traveling wheel 81, a normal traveling wheel 82, and a cross beam 83. Specific embodiments

[0018] The present utility model will be further described in detail below in conjunction with the accompanying drawings and through embodiments. The following embodiments are explanations of the present utility model, and the present utility model is not limited to the following embodiments.

[0019] See Figure 1 - Figure 2 , an auxiliary device for manually withdrawing a boarding bridge in this embodiment includes a first operating rod 1, a connecting rod 2, and a stress rod 3. The connecting rod 2 is fixed to the rear end of the first operating rod 1 and is perpendicular to the first operating rod 1. There are two stress rods 3, and the front ends of the two stress rods 3 are respectively fixed to the left and right ends of the connecting rod 2. The stress rod 3 is parallel to the first operating rod 1, and a connecting ring 31 is provided at the rear end of the stress rod 3.

[0020] When a failure occurs in one of the traveling wheels 8 of the boarding bridge and it is impossible to use a crank to complete the withdrawal of the bridge, first connect the connecting rings 31 on the two stress rods 3 to the traction points inside the two traveling wheels 8 respectively by riveting. The two traveling wheels 8 are driven to move by the motor on the boarding bridge. Among them, the abnormal traveling wheel 81 cannot move due to the damage of its transmission device and cannot achieve synchronous movement with the normal traveling wheel 82. Since the two traveling wheels 8 are horizontally connected by a cross beam 83, when the normal traveling wheel 82 moves, the boarding bridge deflects with the abnormal traveling wheel 81 as the center. At this time, a force opposite to the deflection direction of the boarding bridge is applied to the first operating rod 1 to inhibit the deflection movement of the boarding bridge, achieving the effect of synchronous movement of the abnormal traveling wheel 81 and the normal traveling wheel 82, thereby realizing the withdrawal of the bridge when a certain traveling wheel 8 of the boarding bridge cannot be withdrawn normally using a crank.

[0021] At the same time, when both of the two traveling wheels 8 cannot be driven to move by the motor, it is necessary to manually turn the crank to drive the traveling wheels 8 to move. In order to reduce the situation where the actions of the two traveling wheels 8 are inconsistent due to the difference in the manual turning speed of the crank, one person can turn the crank corresponding to one of the traveling wheels 8, and another person can use the present utility model to inhibit the deflection movement of the boarding bridge through the above operation method, so as to ensure that the actions of the two traveling wheels 8 are consistent during manual bridge withdrawal and reduce the occurrence of deflection accidents of the boarding bridge.

[0022] See Figure 2, a reinforcing rod 4 is arranged between the first operating rod 1 and the connecting rod 2. There are two reinforcing rods 4, and both ends of the reinforcing rod 4 are fixedly connected to the end of the connecting rod 2 and the first connecting rod 2 respectively.

[0023] A stable triangular structure is formed among the reinforcing rod 4, the first operating rod 1 and the connecting rod 2. Through the reinforcing rod 4, the firmness of the connection between the first operating rod 1 and the connecting rod 2 can be improved, and the situation that the connection point between the first operating rod 1 and the connecting rod 2 undergoes large deformation and breaks when the first operating rod 1 is pushed laterally can be reduced. At the same time, the situation that the first operating rod 1 bends due to excessive deformation can also be reduced. Therefore, through the reinforcing rod 4, the anti-deformation ability during the use of the present utility model can be improved, and the safety and service life during the use of the present utility model can be improved.

[0024] See Figure 2 , a second operating rod 5 is arranged at the front end of the first operating rod 1. A first external thread 11 and a first internal thread 51 which are matched with each other are arranged at the front end of the first operating rod 1 and the rear end of the second operating rod 5.

[0025] When the present utility model is in use, the second operating rod 5 is fixed on the first operation by means of the threaded connection between the first external thread 11 and the first internal thread 51. According to the lever principle, the power arm and the pushable space during the use of the present utility model are extended through the second operating rod 5, so that it is convenient for the user to apply a lateral force to the first operating rod 1 and the second operating rod 5 to maintain the synchronous movement of the two traveling wheels 8.

[0026] See Figure 2 , a tail rod 6 is arranged at the front end of the second operating rod 5. A second external thread 52 and a second internal thread 61 which are matched with each other are arranged at the front end of the second operating rod 5 and the rear end of the tail rod 6. A handle 62 is arranged on the side surface of the tail rod 6.

[0027] Through the tail rod 6, the power arm and the pushable space during the use of the present utility model are further extended on the basis of the second operating rod 5. At the same time, the handle 62 also facilitates the user to pull the present utility model from the side, improving the convenience of operation of the present utility model.

[0028] In this embodiment, multiple second operating rods 5 can be fixedly connected end to end by threads according to actual situations to extend the overall length of the first operating rod 1 and the second operating rod 5, which is convenient for the user to apply a lateral force to the first operating rod 1 and the second operating rod 5 to maintain the synchronous movement of the two traveling wheels 8.

[0029] See Figure 1 , a universal wheel fixing rod 7 is arranged on the first operating rod 1. A universal wheel 71 is arranged at the lower end of the universal wheel fixing rod 7.

[0030] The universal wheel fixing rod 7 and the universal wheel 71 can provide an upward vertical supporting force to counteract the gravity effect of the present utility model. At the same time, the universal wheel 71 can facilitate the movement of the first operating rod 1 and the second operating rod 5 in the opposite direction of the deflection movement towards the traveling wheel 8.

[0031] See Figure 1 , a jack 72 is provided on the universal wheel fixing rod 7, and the first operating rod 1 and the second operating rod 5 are slidably inserted into the jack 72 in a matching manner.

[0032] The sliding plug connection between the universal wheel fixing rod 7 and the first operating rod 1 and the second operating rod 5 can facilitate the installation of the universal wheel fixing rod 7 on the first operating rod 1 when the present utility model is in use, and drive the universal wheel fixing rod 7 to slide on the first operating rod 1 and the second operating rod 5 according to the length of the second operating rod 5 and the operating position of the user to adjust the position of the universal wheel 71, thereby improving the convenience of use of the present utility model.
