Description

Trailer loading and unloading linkage bridge plate mechanism of damaged aircraft rapid dragging system Technical Field The invention relates to the technical field of aviation, in particular to a linkage bridge plate mechanism for loading and unloading a trailer of a rapid dragging system of a damaged aircraft. Background The aircraft is abnormal in the lifting process, so that the landing gear is damaged, the normal operation of an airport is affected, and special moving equipment is needed for emergency moving rescue of the accident aircraft. In the prior art, a plurality of related patent technologies for the trailer for the fault movement of the landing gear have technical defects, which are not stable enough, not fast enough and not safe enough, so that a novel emergency dragging device capable of being fast and safely assembled and disassembled needs to be designed. Disclosure of Invention The invention aims to provide a trailer loading and unloading linkage bridge plate mechanism of a damaged aircraft rapid hauling system, which is used for solving at least one of the problems in the prior art. In order to achieve the above purpose, the present invention adopts the following technical scheme: The utility model provides a damaged aircraft drags system trailer loading and unloading linkage bridge plate mechanism, includes the automobile body, the front end and the rear end of automobile body are equipped with the drive wheel of liftable respectively, the left and right sides symmetry of automobile body is equipped with the bearing wheel elevation structure, the bearing wheel elevation structure includes first pneumatic cylinder, second pneumatic cylinder, first bearing wheel, second bearing wheel, first swivel mount and second swivel mount all include the first articulated position, second articulated position and the third articulated position that are triangle-shaped and distribute, two first articulated positions are connected with the rotation between the automobile body respectively, two second articulated positions are connected with first bearing wheel and second bearing wheel rotation respectively, first pneumatic cylinder sets up between the first articulated position of first swivel mount and the third articulated position of second swivel mount, the second pneumatic cylinder sets up between the third articulated position of first swivel mount and the first articulated position of second swivel mount; The rear end rotation of automobile body is connected with liftable bridge plate, and liftable bridge plate includes bridge plate, pivot and pressure portion, the bridge plate rotates with the rear end of automobile body through the pivot and is connected, pressure portion sets up the position that is close to the pivot and extends towards the outside, thereby the second runing rest clockwise rotation in-process with pressure portion butt and continuously exert pressure thereby the driving bridge plate with the pivot as center of rotation towards the direction swing of keeping away from the ground, the anticlockwise rotation in-process with pressure portion break away from gradually so that the bridge plate swings with the pivot as center of rotation towards the direction of being close to the ground under the effect of dead weight. In the technical scheme, the lifting driving wheels are respectively arranged at the front end and the rear end of the vehicle body, the bearing wheel lifting structures are symmetrically arranged at the left side and the right side of the vehicle body, the lifting driving wheels and the bearing wheel lifting structures are combined, the use of the driving wheels and the bearing wheels can be switched according to the use requirement, the driving wheels are easy to control in the driving process, the vehicle body can move to a position suitable for loading the landing gear more accurately, meanwhile, when the landing gear is loaded on the vehicle body, the landing gear is heavier, at the moment, the bearing wheels are put down to lift the driving wheels, and under the action of an external trailer, the bearing wheels are used as follower wheels, so that the landing gear can be transferred reliably and efficiently. When the bearing wheel is in a lifting state, the driving wheel is in a descending state and is contacted with the ground, and the size of the driving wheel is smaller than that of the bearing wheel and the driving wheel is provided with a self-driving system, so that the steering and movement of the driving wheel are more flexible, and the vehicle body can be more efficiently moved to a position convenient for loading the landing gear. Specifically, when the undercarriage is loaded on the car body and the undercarriage needs to be transferred, the first hydraulic cylinder and the second hydraulic cylinder simultaneously drive the first rotating support and the second rotating support to rotate respectively by taking the first hinging position as a fulcrum,
