Adjusting mechanism of towing hook on aircraft tractor

Abstract

The invention provides an adjusting mechanism of a towing hook on an aircraft tractor, and belongs to the technical field of aircraft traction equipment. The technical problem that connection between a traction rod and a tractor is troublesome is solved. The adjusting mechanism for the towing hook on the aircraft tractor comprises a mounting seat fixedly connected with a frame of the aircraft tractor, and a first ratchet rack and a second ratchet rack which are arranged side by side are arranged on the side face of the mounting seat. A first mounting strip extending towards the upper part of the first ratchet rack and a second mounting strip extending towards the lower part of the first ratchet rack are arranged on one side of a seat body of the traction hook; a first pawl clamped with the first ratchet rack and a second pawl clamped with the second ratchet rack are respectively arranged on the first mounting strip; a push rod capable of pushing the first pawl to be separated from the first ratchet rack and the second pawl to be separated from the second ratchet rack is arranged on the second mounting strip; and a translation hydraulic oil cylinder is arranged between the seat body of the traction hook and the mounting seat. According to the adjusting mechanism, butt joint of the aircraft tractor and the traction rod is realized very conveniently.

Description

technical field [0001] The invention belongs to the technical field of aircraft traction equipment, and relates to an adjustment mechanism for a traction hook on an aircraft tractor. Background technique [0002] Aircraft tractor is a kind of support equipment for towing aircraft on the ground of the airport, and it can also be used to move large parts of the aircraft or the aircraft during the aircraft manufacturing process. The tow bar is usually used for detachable connection between the aircraft tractor and the aircraft. The tow bar is generally set independently. When the tow bar is needed, the tow hook on the aircraft tractor is connected with the connecting ring on one end of the tow bar, and the other end of the tow bar docks with the aircraft, and then starts to drag the aircraft; A set of docking actions is observed by a special person, commanding the docking, which is very troublesome, and the labor intensity of the docking personnel is high, and both operation a...

AI Technical Summary

Problems solved by technology

[0003] The towing hook on the existing aircraft tractor is fixed on the aircraft towing vehicle, and cannot be adjusted forward and backward. On the premise that the tow bar is connected to the aircraft, if there is a certain distance between the tow bar and the tow hook, the tow bar and the tow hook cannot be adjusted. The towing hook on the tractor is connected. At this time, it is necessary to restart the tractor, adjust the position of the tractor forward and backward, and align the tow bar and the towing hook of the tractor before assembling the traction pin to realize the towing of the aircraft.

Such a docking method is very troublesome, and the position of the tractor needs to be adjusted many times. At the same time, a person is required to observe the command behind the vehicle, which affects work efficiency and increases labor costs. There is also a certain safety risk for the command personnel at the rear of the vehicle.
