[0006] The present application provides an electric hook of an airport tractor to solve the above problems in the prior art. The technical problem to be solved by the present application is how to improve the simplicity, stability and reliability of the hook in the airport tractor and reduce pollution.

[0007] The object of the present application can be achieved by the following technical solutions:

[0008] The electric hook of the airport tractor comprises a traction bolt base and a sliding plate; the traction bolt base is provided with vertical guide rails; the sliding plate is slidably connected to the traction bolt base through the guide rails; the traction bolt base is fixedly provided with an electric push rod capable of driving the sliding plate to move up and down; the traction bolt base is fixedly provided with a horizontal first limiting plate and a horizontal second limiting plate on the side facing the sliding plate; the first limiting plate and the second limiting plate are arranged in an up-down spaced manner; the first limiting plate is provided with a first through hole; the second limiting plate is provided with a second through hole opposite to the first through hole; the sliding plate is connected with a vertical bolt pin; the bolt pin is opposite to the first through hole and the second through hole and can pass through the first through hole and the second through hole in sequence; and the length of the bolt pin is greater than the spacing distance between the first limiting plate and the second limiting plate.

[0009] The implementation principle is as follows: the electric hook is fixedly installed at the rear end of the tractor through the traction bolt base, which can be welded or fixedly connected through bolts. The forward direction of the tractor is regarded as the front, and the backward direction of the tractor is regarded as the rear. The sliding plate is installed at the rear side of the traction bolt base. When in use, the front end of the device to be towed is provided with a hook ring. When the hook is automatically connected, the electric push rod drives the sliding plate and the bolt pin to move upward. When the lower end of the bolt pin is flush with the first limiting plate, the hook ring is clamped between the first limiting plate and the second limiting plate. Then, the electric push rod drives the sliding plate and the bolt pin to move downward. After the bolt pin passes through the hook ring and continues to descend, the bolt pin is inserted into the second through hole of the second limiting plate, thereby achieving the locking of the hook ring. When the hook is automatically disconnected, the electric push rod drives the sliding plate and the bolt pin to move upward. When the lower end of the bolt pin is flush with the first limiting plate, the hook ring can be disconnected from between the first limiting plate and the second limiting plate. The technical solution has a simple structure, the action of the bolt pin driven by the electric push rod is accurate and reliable, and the whole process can realize the automatic insertion and extraction of the bolt pin without manual operation.

[0010] In the electric hook of the airport tractor, the top of the traction bolt base is provided with an upward extending vertical plate; the upper end of the vertical plate is bent to form an installation platform on the side of the sliding plate; the installation platform is fixedly provided with an installation support on the upper side; the electric push rod is fixedly arranged on the installation support and vertically arranged downward; the installation platform is provided with a third through hole; and the driving rod of the electric push rod passes through the third through hole and is connected with the sliding plate. The electric push rod directly pushes the sliding plate and the bolt pin to move upward and downward without additional transmission components or conversion components, thereby simplifying the structure and making the action accurate and reliable.

The detection sensor is mounted on the first detection bracket, and when the bolt moves downward to the position, the detection sensor can detect, so as to transmit the signal to the main controller, thereby judging whether it can work normally.

[0016] In the electric hook of the airport tractor, the bottom of the two sliding plates is fixedly connected with a second bottom plate, one side of the second bottom plate is provided with a gap for staggering with the first bottom plate, and the other side of the second bottom plate is provided with a first guide plate extending downward. The second bottom plate moves up and down with the sliding plate, and by providing the gap, interference between the second bottom plate and the first bottom plate during the up-and-down movement of the second bottom plate is avoided, and the movement range of the second bottom plate is expanded.
