Description

Track centering correction device

Technical Field

The invention belongs to the field of track centering correction, and particularly relates to a track centering correction device.

Background

The trolley may not be perfectly aligned with the track before entering the track due to positional deviations during travel. Therefore, a track centering correction device is required to be designed, so that the wheel set of the trolley and the track are centered and corrected firstly, and the trolley can enter the track smoothly.

Disclosure of Invention

In order to solve the problem that the trolley is not completely aligned with the track to be entered, the invention provides a track centering correction device which enables the wheel set of the trolley to be centered with the track first so as to ensure that the trolley smoothly enters the track.

In order to achieve the above purpose, the invention is realized by the following technical scheme:

The track centering correction device comprises a frame and is characterized in that a center support is arranged on the frame, pushing arms are respectively arranged on two sides of the center support, the bottom ends of the pushing arms are respectively rotatably arranged on the frame, pushing wheels are rotatably arranged on the top ends of the pushing arms, the middle section of the pushing arms is rotatably arranged at the end part of an extending shaft of an oil cylinder, and the oil cylinders are respectively rotatably arranged on two sides of the frame.

It is further characterized by:

limit switches are respectively arranged on two sides of the center support;

the three rotation centers on the push arm form a triangle.

The trolley has the beneficial effects that when the wheel set of the trolley advances to the track, the oil cylinders at the two sides respectively push the push arms to rotate, the push wheels at the top ends of the push arms respectively hug the beam under the trolley from the two sides, so that the wheel set of the trolley and the track are centered and corrected, the trolley can be ensured to smoothly enter the track, the limit switch is used for detecting the hugging position and the opening position of the push arms, and the three rotation centers on the push arms form a triangle, so that the stress is convenient.

Drawings

FIG. 1 is a schematic view of the overall structure of the present invention;

in the figure, a frame 1, a center support 2, a push arm 3, a push wheel 4, an oil cylinder 5 and a limit switch 6.

Detailed Description

The present invention will be further described in detail with reference to the drawings and examples, which are only for the purpose of illustrating the invention and are not to be construed as limiting the scope of the invention.

The rail centering correction device comprises a frame 1, wherein a center support 2 is arranged on the frame 1, push arms 3 are respectively arranged on two sides of the center support 2, the bottom ends of the push arms 3 are respectively rotatably arranged on the frame 1, push wheels 4 are rotatably arranged on the top ends of the push arms, the middle section of the push arms is rotatably arranged on the end part of an extending shaft of an oil cylinder 5, and the oil cylinder 5 is respectively rotatably arranged on two sides of the frame 1. The two sides of the center bracket 2 are respectively provided with an oil cylinder 6, and three rotation centers on the pushing arm 3 form a triangle.

The trolley has the beneficial effects that when the wheel set of the trolley advances to the track, the oil cylinders 5 on two sides respectively push the push arms 3 to rotate, the push wheels 4 on the top ends of the push arms 3 respectively hug the beams under the trolley from two sides, so that the wheel set of the trolley and the track are centered and corrected, the trolley can be ensured to smoothly enter the track, the oil cylinders 6 are used for detecting the hugging position and the opening position of the push arms 3, and three rotation centers on the push arms 3 form a triangle, so that stress is convenient.

Claims

1. A track centering correction device, comprising a frame, characterized in that: a central support is mounted on the frame, push arms are respectively arranged on both sides of the central support, the push arms are respectively rotatably mounted on the frame at the bottom ends, push wheels are rotatably mounted on the top ends, the middle sections are rotatably mounted on the extended shaft ends of the oil cylinders, and the oil cylinders are respectively rotatably mounted on both sides of the frame;

The three rotation centers on the push arm form a triangle.
