Description

Nut follower type electromechanical lift boarding bridge

technical field

The utility model relates to a lifting boarding bridge, in particular to a nut-following electromechanical lifting boarding bridge.

Background technique

The boarding bridge is usually composed of several sections of retractable channel sockets, which can be extended to the door of the aircraft and docked with it when the aircraft is getting on and off the passengers, so that passengers can transfer between the aircraft parking place and the terminal building in the airport , and the aircraft models are different, the height of the aircraft door is also different, so it is necessary to use a lifting device to adjust the height of the passage.

At present, the electromechanical boarding bridge adopts the structure that the screw rod is connected with the outer conduit, and the nut is connected with the inner conduit. However, no matter whether it is the design of screw screw lifting or screw nut lifting, the vertical distance of the nut relative to the ground remains unchanged, and the screw rod is connected with the outer conduit. Under the action of the driving force, the screw rod drives the outer conduit to move up and down to achieve Purpose of lift boarding bridge. However, this structure is basically that the speed reducer and the motor are located at the top of the channel. Because of the high position, it is inconvenient to repair and maintain the motor and the speed reducer, and there are certain unsafe factors. It is also necessary to use the cooperation of truck cranes and the cooperation of special operators and crane workers, which makes the required cost higher.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a nut-lifting electromechanical bridge with a drive mechanism placed underneath.

The technical scheme that the utility model solves its technical problem adopts is:

The nut-following type electromechanical lifting boarding bridge is characterized in that it includes a bottom support and a driving mechanism. The driving mechanism is arranged on any position of the bottom support. The outer conduit connected to the passage of the boarding bridge has a screw rod inside the inner conduit. One end of the screw rod is installed in the inner conduit through a bearing, and the screw rod is connected to the output end of the driving mechanism through a coupling. A screw nut is provided, and a connecting pipe is set outside the screw rod, and the two ends of the connecting pipe are respectively connected with the screw nut and the outer conduit.

A guide slider is provided on the outer wall of the inner conduit.

The drive mechanism is a geared motor.

The beneficial effects of the utility model are: the utility model includes a bottom support and a driving mechanism, the drive mechanism is arranged on any position of the bottom support, an inner conduit is provided on the bottom support, and the inner conduit is sleeved with a boarding bridge. The outer conduit connected with the channel, the inner conduit is provided with a screw rod, one end of the screw rod is connected to the inner conduit through a bearing, and the screw rod is connected to the output end of the driving mechanism through a coupling, and a screw nut is provided on the screw rod , the outer cover of the screw rod is provided with a connecting pipe, and the two ends of the connecting pipe are respectively connected with the screw nut and the outer conduit. In the above structure, the screw nut and the channel are integrated through the connecting seat, and as the screw rotates, the screw nut drives the channel to realize the lifting function. The installation and maintenance of the motor and the reducer of the utility model only need to be carried out on the ground, and a manual forklift can be used to cooperate, and the maintenance is convenient. Safety, reduced manpower and material consumption, and improved economy make the electromechanical boarding bridge more adaptable to the requirements of a low-carbon economy.
