Description
Technical Field
The invention relates to the technical field of cargo transportation, in particular to a novel telescopic interlocking pin shaft device of a gangway of a car and an airplane.
Background
In consideration of maximization of loading capacity of the car, most manufacturers are equipped with a lifting type single car loading platform (commonly called an aircraft gangway) on the car loading platform, and after the transported car is driven on the aircraft gangway and fixed firmly, one end of the aircraft gangway is lifted until a certain angle is formed with the horizontal plane, so that the space occupied by the transported car in the length direction is shortened, and more vehicles can be loaded on the transported car in the length direction. Considering the multipurpose type of the aircraft springboard, part of manufacturers can design the aircraft springboard into a structure form with two reversible ends, one end can be fixed at will and then the other end can be driven to be turned upwards to rise (the front end is fixed to turn over the rear end/the rear end is fixed to turn over the front end, hereinafter, the front turning over or the rear turning over is abbreviated as a front turning over mode), but if the front turning over mode is changed into the rear turning over mode, the aircraft springboard must be changed into the front hinging and fixing state from the rear hinging and fixing state, the traditional mode is that the hinging positions on the left side and the right side of the rear end of the aircraft springboard are firstly manually loosened, and then the hinging positions on the two sides of the front end of the aircraft springboard are manually locked, so that an operator can finish unlocking and locking operations on the 4 positions (the front hinging position and the rear hinging positions are positioned at four corners of the aircraft springboard) by winding around the aircraft springboard, the time is more, the efficiency is lower, and misoperation is easy.

A novel telescopic interlocking pin shaft device of a car transporting airplane springboard is characterized in that a push-pull flexible shaft is U-shaped in overlooking mode.
A novel telescopic interlocking pin shaft device of a car transporting airplane springboard is characterized in that an operating handle is arranged at the bottom of a push-pull flexible shaft.
Compared with the prior art, the invention has the beneficial effects that:
the invention can realize single-handle operation to drive the hinge pins at the two sides of the front end of the aircraft springboard to simultaneously extend and the hinge pins at the two sides of the rear end to simultaneously retract, or the hinge pins at the two sides of the rear end to simultaneously extend and the hinge pins at the two sides of the front end to simultaneously retract, thereby realizing the rapid switching of forward turning and backward turning modes of the aircraft springboard.
According to the invention, only a single person is required to operate the aircraft gangway from the front end hinged fixed state to the rear end hinged fixed state, so that the operation efficiency is improved; the invention realizes that the front and rear of the aircraft springboard can not be in an unlocked state or an unlocked misoperation state, and always ensures that the front and rear are in an interlocking state, namely the rear end is automatically in an unlocking state when the front end is locked, and vice versa.

Detailed Description
Example 1:
referring to fig. 1-5, the novel telescopic interlocking pin shaft device of the car and airplane springboard comprises an airplane springboard 1, telescopic pin shafts 2 on two sides of the front end, connecting rods 3 on two sides of the front end, a front end center rotating shifting sheet 4, a push-pull flexible shaft 5, a rear end center rotating shifting sheet 6, connecting rods 7 on two sides of the rear end and telescopic pin shafts 8 on two sides of the rear end.
Front end center rotation plectrum 4 is installed in the front end crossbeam central point of aircraft springboard 1 with articulated mode, and front end both sides connecting rod 3 contains two front end connecting rods, two front end connecting rods bilateral symmetry set up in front end center rotation plectrum 4 both sides and articulated with front end center rotation plectrum 4, front end both sides telescopic pin axle 2 contains two front end telescopic pin axles, two front end telescopic pin axles set up respectively in two front end connecting rods and articulated with front end both sides connecting rod 3.
The rear end center rotation plectrum 6 is installed in the rear end crossbeam central point of aircraft springboard 1 with articulated mode, and rear end both sides connecting rod 7 contains two rear end connecting rods, two rear end connecting rods bilateral symmetry set up in rear end center rotation plectrum 6 both sides and articulated with rear end center rotation plectrum 6, and rear end both sides flexible round pin axle 8 contains two rear end flexible round pin axles, two rear end flexible round pin axles set up respectively in two rear end connecting rods and articulated with rear end both sides connecting rod 3.
The push-pull flexible shaft 5 is U-shaped in overlook, two ends of the push-pull flexible shaft 5 are respectively hinged with the front end center rotating shifting piece 4 and the rear end center rotating shifting piece 6, and an operating handle is arranged at the bottom of the push-pull flexible shaft 5.
Working principle:
when the operating handle of the push-pull flexible shaft 5 is pulled forwards, one end of the push-pull flexible shaft 5 near the front is lengthened, the other end near the rear is shortened, the front end is pushed to rotate to a certain angle by the lengthened front center rotary pulling piece 4, the front end center rotary pulling piece 4 pushes the front end two side connecting rods 3 to extend outwards in the rotating process, and the front end two side connecting rods 3 push the front end two side telescopic pin shafts 2 to extend outwards in the extending process and insert into holes formed in nearby structural members, so that the hinge points of the front end two sides are locked. At the same time of the above actions, the rear end of the push-pull flexible shaft 5 is shortened to pull the rear end center rotary pulling piece 6 to rotate to a certain angle, the rear end center rotary pulling piece 6 pulls the rear end two side connecting rods 7 to retract inwards in the rotating process, and the rear end two side connecting rods 7 pull the rear end two side telescopic pin shafts 8 to retract inwards in the retracting process, so that the rear end two side telescopic pin shafts 8 are separated from holes formed in nearby structural members, and the hinge points of the two sides of the rear end are unlocked.
If the handle of the push-pull flexible shaft 5 is pulled backwards, the actions are all opposite, and finally, the telescopic pin shafts 2 at the two sides of the front end of the aircraft springboard 1 retract inwards to unlock, and the telescopic pin shafts 8 at the two sides of the rear end extend outwards to lock.
The foregoing is merely a specific application example of the present invention, and the protection scope of the present invention is not limited in any way. All technical schemes formed by equivalent transformation or equivalent substitution fall within the protection scope of the invention.
