Car carrier aircraft springboard novel extension interlocking pin shaft device

Abstract

The invention relates to a car carrier aircraft springboard novel extension interlocking pin shaft device. The device comprises an aircraft springboard, front end two side extension pin shafts, frontend two side connecting rods, a front end center rotary poking piece, a push-pull flexible shaft, a back end center rotary poking piece, back end two side connecting rods and back end two side extension pin shafts; the front end center rotary poking piece is hinged in the center position of a front end cross beam of the aircraft springboard; the front end two side connecting rods are hinged with the front end center rotary poking piece; the front end two side extension pin shafts are hinged with the front end two side connecting rods; the back end center rotary poking piece is hinged in the center position of a back end cross beam of the aircraft springboard; the back end two side connecting rods are hinged with the back end center rotary poking piece; the back end two side extension pin shafts are hinged with the back end two side connecting rods; and the two ends of the push-pull flexible shaft are hinged with the front end center rotary poking piece and the back end center rotary poking piece. The switching of the aircraft springboard from a front end hinge fixed state to a back end hinge fixed state is only operated by one step through one person, so that the operation efficiency is improved, and the front-back interlocking state is always guaranteed.

Description

technical field [0001] The invention relates to the technical field of cargo transportation, in particular to a novel telescopic interlocking pin shaft device for a car carrier and an aircraft springboard. Background technique [0002] Considering the maximization of the loading capacity of the car carrier, most manufacturers equip the car carrier loading platform with a liftable single-vehicle loading platform (commonly known as "aircraft springboard"). One end of the springboard rises until it forms a certain angle with the horizontal plane, thereby shortening the space occupied by the transported vehicle in the length direction, so that the transport vehicle can load more vehicles in the length direction. Considering the multi-purpose type of this aircraft springboard, some manufacturers will design it as a structure that can be turned over at both ends, that is, one end can be fixed arbitrarily and then the other end can be driven up (fixed at the front end to turn over ...

Problems solved by technology

Considering the multi-purpose type of this aircraft springboard, some manufacturers will design it as a structure that can be turned over at both ends, that is, one end can be fixed arbitrarily and then the other end can be driven up to raise (fixed front end flips rear end / rear end fixed flips front end , hereinafter referred to as "front flip" or "back flip"), but if you want to change from the front flip mode to the back flip mode, you must first change the aircraft springboard from the rear-end hinged fixed state to the front-end hinged fixed state. Manually loosen the hinges on the left and right sides of the rear end of the aircraft springboard, and then manually lock the hinges on both sides of the front end of the aircraft springboard, so that the operator needs to walk around the aircraft springboard to complete the unlocking and locking of the above four places Operation (the front and rear 4 hinges are located at the four corners of the aircraft springboard), it takes a lot of time, the efficiency is low and it is easy to misuse
