Abstract

The utility model discloses an automatic trailer parking device, including traction frame, spout, link means, braking single arm -drag, the traction frame lower extreme is equipped with the spout, and the spout is arranged in to link means one end head, and the braking single arm -drag is connected to the link means other end, and left and right coaster brake hub is connected respectively at both ends about the braking single arm -drag. Its simple structure need not the operating personnel handle and stops in the use, utilize simple mechanical transmission to turn into the brake force of brakeing the single arm -drag with the gravity of traction frame, realizes parking braking, convenient to use.

Description

An automatic trailer parking device

technical field

The utility model belongs to a special device for aviation ground support, in particular to a device which enables a trailer to produce a parking brake through simple mechanical transmission.

Background technique

The trailer parking brake device is mainly used in cargo trailers at airports or railway stations. When the existing trailer is parked, the operator needs to pull the handbrake. If the operator forgets to pull the handbrake after improper use, the trailer will continue to move forward, causing a series of problems.

Utility model content

Aiming at the deficiencies of the prior art, the purpose of this utility model is to provide an automatic trailer parking device, which avoids the need to pull the handbrake to park the trailer when it is in use.

In order to achieve the above object, the utility model adopts the following technical solutions:

An automatic trailer parking device, comprising a traction frame, a chute, a T-shaped connecting rod device, and a brake pull arm; Both ends of the bottom of the rod device are respectively connected to brake pull arms, and the brake pull arms are respectively connected to the left and right brake hubs.

Further, a locking nut is provided on the T-shaped connecting rod device.

When the operator releases the traction frame from the traction seat at the back of the tractor and lowers it slowly, under the action of gravity, the head of the T-shaped link device slides down in the chute, making the T-shaped link device move and suppress the brake pull. The arm acts on the left and right brake hubs to produce a parking brake effect. If the brake shoes in the brake hub are severely worn due to long-term use, which makes the braking effect worse, you can adjust the lock nut on the connecting rod device to make the connecting rod device longer, which can improve the braking effect. car braking effect.

The beneficial effect of the utility model lies in that the structure is simple, the operator does not need to pull the handbrake during use, the gravity of the traction frame is converted into the braking force of the brake pull arm by simple mechanical transmission, and the parking brake is realized, which is convenient to use.

detailed description

Below in conjunction with accompanying drawing, the utility model is further elaborated.

Example 1

As shown in Figure 1-2, an automatic trailer parking device is mainly composed of a traction frame (1), a chute (2), a T-shaped connecting rod device (3), a lock nut (4), and a brake pull arm (5) Composition. The lower end of the traction frame (1) is provided with a chute (2), the head of the T-shaped connecting rod device (3) is placed in the chute (2), and the T-shaped connecting rod device (3) is provided with a lock nut (4) , the two ends of the bottom of the T-shaped connecting rod device (3) are respectively connected to the brake pull arm (5), and the brake pull arm (5) is connected to the left and right brake hubs (6 and 7).

When the operator releases the traction frame (1) from the traction seat at the back of the tractor and lowers it slowly, under the action of gravity, the head of the T-shaped linkage device (3) slides down in the chute (2), making the T-shaped linkage The rod device (3) moves, suppresses the brake pull arm (5), and acts on the left and right brake hubs (6 and 7) to produce a parking brake effect. If the brake shoes in the brake hub are severely worn due to long-term use, making the braking effect worse, you can adjust the lock nut (4) on the connecting rod device to make the connecting rod device longer, so that Can improve the parking brake effect.

Claims (2)
