Through radially opening, the balanced centre gripping of the second shaft 22 can be realized to every locking block 35, and the setting that the number of activity holes 241 is no less than five, that is to say, the number of corresponding locking blocks 35 is no less than five, can guarantee that the locking intensity between the second shaft 22 and the second gear 24 is guaranteed. When the temperature is reduced, the reset adjustment can be carried out, and the support is also released.
The working principle is as follows: when the fixed bridge head of the boarding bridge is installed and used by a supporting device with an adjusting function, the whole device is supported, protected and insulated by the shell 1; when the boarding bridge is used, the shell 1 is placed under the boarding bridge head 18, the motor 3 is powered on, and an output shaft on the motor 3 drives the first shaft 4 to rotate; the cylindrical cam 5 is driven to rotate through the first shaft 4; because the piston 9 can only slide up and down in the vertical section of the three-way pipe 8, the motion trails of the transmission arm 7 on the piston 9 and the sliding block 6 on the top of the transmission arm 7 are limited, when the cylindrical cam 5 rotates, the sliding groove of the outer contour on the cylindrical cam 5 and the surface of the sliding block 6 can slide relatively, and the sliding block 6 can realize the reciprocating lifting of the piston 9 through the transmission arm 7 under the guidance of the sliding groove; when the piston 9 moves downwards in the vertical section of the three-way pipe 8, the gas in the middle space of the three-way pipe 8 enters the sleeve 11 through the one-way valve one 10 close to one side of the sleeve 11 and finally enters the air bag 12, when the piston 9 moves upwards in the vertical end of the three-way pipe 8, the air pressure in the middle space of the three-way pipe 8 is reduced, the air at the normal pressure outside enters the middle space of the three-way pipe 8 through the one-way valve one 10 in the three-way pipe 8 far away from the sleeve 11, namely, the air in the three-way pipe 8 is discharged and sucked through one-time downward movement and upward movement, when the transmission arm 7 drives the piston 9 to reciprocate in the vertical section of the three-way pipe 8, the outside air is continuously sucked into the three-way pipe 8 and then discharged into the air bag 12, the gas in the air bag 12 is increased, the volume is continuously expanded, and the supporting block 13 can be pushed out downwards from the shell 1, the supporting block 13 contacted with the ground is continuously exposed out of the shell 1, so that the overall height of the shell 1 is continuously increased, and a transverse plate II 17 at the top of the shell 1 can be contacted with the surface of a boarding bridge head 18; when the boarding bridge head 18 is used, the boarding bridge head 18 can incline at a certain angle through continuous adjustment, and a transverse plate II 17 in contact with the lower surface of the boarding bridge head 18 can drive a transverse plate I15 on a supporting plate 14 to drive the transverse plate II 17 to rotate through a connecting rod 16 along with the continuous upward movement of the shell 1; at this time, the boarding bridgehead 18 is already matched with the airplane cabin door, so that the boarding bridgehead 18 cannot be extruded with high strength, the matching accuracy is stable, and the boarding bridgehead 18 is prevented from being rubbed with the airplane cabin door. At the moment, the rotation of the transverse plate II 17 is slowly carried out, so that the boarding bridge head 18 is not severely extruded; in the initial rotating process, the transverse plate I15 and the transverse plate II 17 rotate according to the inclination degree of the boarding bridge head 18, so that the lower surface of the transverse plate I15 is matched with the auxiliary device 19, the auxiliary device 19 can be continuously adjusted in a lifting mode, a self-adaptive supporting effect is achieved, three-point support is formed by the auxiliary support of the transverse plate II 17 through the auxiliary device 19, pin shaft connection at the supporting plate 14 and contact of the transverse plate II 17 and the lower surface of the boarding bridge head 18, high stability is achieved, and the inclined plane of the transverse plate II 17 and the inclined plane of the boarding bridge head 18 are completely attached, so that the integrity degree of support can be further improved; the supported transverse plate II 17 is only in contact with the boarding bridge head 18 and does not generate substantial upward lifting for the boarding bridge head 18, so that the boarding bridge head 18 can be prevented from deviating, but once a passenger moves downwards and shakes when passing through the boarding bridge head 18, the self-adaptive adjusted transverse plate II 17 can lift the boarding bridge head 18 when moving downwards, and the expanded air bag 12 can play a role in buffering and damping, so that the boarding bridge head 18 is supported more fully and completely; through the cooperation use between the above-mentioned structure, solved in the in-service use, because traditional boarding bridge head is located the tip of boarding bridge, often can have the slope of certain angle when adjusting and aircraft hatch butt joint use, and because the support of boarding bridge head department exists inadequately, when the passenger passes through the boarding bridge head, often can cause slight rocking of boarding bridge head, bring inconvenience for passenger's walking, have the problem of potential safety hazard.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
