Aerobridge lifting device and method for adjusting same

Abstract

The invention discloses an aerobridge lifting device and a method for adjusting same. The aerobridge lifting device comprises a first upright post and a second upright post which are arranged on two sides of a channel; each upright post comprises an inner sleeve, an outer sleeve and a control device, wherein the inner sleeve is fixed with a traveling gear; the outer sleeve is sleeved on the innersleeve and can be driven to lift relatively to the inner sleeve and is fixed with the channel; and the control device is respectively provided with an automatic leveling mode unit, a manual leveling mode unit and a single post correcting mode unit. The method comprises the following steps: a first stage limit switch is arranged at the lower end of the outer sleeve close to each upright post, wherein the first stage limit switch acts when the offset of the height of the first or second upright post reaches a first preset threshold; the first stage limit switch is monitored; in the moving process of the aerobridge lifting device, the action of the first stage limit switch from any upright post is judged, if the fist stage limit switch acts, one of the upright posts is delayed for one presettime and then moves along with the other upright post.

Description

technical field [0001] The invention relates to a boarding bridge for transporting passengers, in particular to an adjustment method for a lifting device of the boarding bridge and the lifting device thereof. Background technique [0002] The boarding bridge is the main airport auxiliary equipment for transporting passengers which has been widely used. FIG. 1 shows a schematic diagram of an electromechanical boarding bridge 10 . Since the passage 12 needs to be docked with the cabin door of an aircraft, the lifting device 14 for supporting the passage 12 is one of the important components of the boarding bridge 10 . The lifting device has uprights 142 arranged on both sides of the channel 12 , therefore, ensuring the synchronous lifting of the two uprights is the guarantee for the safe operation of the boarding bridge 10 . [0003] Chinese patent ZL96250710.5 discloses a synchronous adjustment device for boarding bridges, such as figure 2 As shown, the left and right colum...

AI Technical Summary

Problems solved by technology

[0005] Although the boarding bridge synchronous adjustment device in the above-mentioned patent can better automatically correct the lifting of the boarding bridge, these travel switches are arranged on the top of the column, which is inconvenient in installation, adjustment and maintenance.

In addition, the adjustment device of this structure has high requirements on the operating skills of the operators, and the operators need to undergo professional training.

If due to the misoperation of the operator, or other untrained personnel not adjusting according to the specifications, it will cause the transitional lifting or lowering of the single column, resulting in mechanical damage to the lifting column.
