The device comprises a frame, a central bracket is mounted on the frame, push arms are respectively arranged on both sides of the central bracket, the bottom ends of the push arms are rotatably mounted on the frame, the top ends are rotatably mounted with push wheels, 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.

Description

Technical Field

[0001] The present invention belongs to the field of track centering and correction, and specifically relates to a track centering and correction device. Background Art

[0002] Before the trolley enters the track, it may not be completely aligned with the track due to position deviation during the traveling process. Therefore, it is necessary to design a track centering and correction device to center and correct the wheel set of the trolley with the track first, so as to ensure that the trolley can smoothly enter the track. Summary of the Invention

[0003] To solve the problem that the trolley is not completely aligned with the upcoming track, the present invention provides a track centering and correction device, which centers and corrects the wheel set of the trolley with the track first, so as to ensure that the trolley can smoothly enter the track.

[0004] To achieve the above object, the present invention is realized through the following technical solutions:

[0005] A track centering and correction device, which includes a frame, and is characterized in that: a central support is installed on the frame, push arms are respectively arranged on both sides of the central support, the bottom ends of the push arms are rotatably installed on the frame respectively, the top ends are rotatably installed with push wheels, and the middle sections are rotatably installed at the end parts of the extending shafts of the oil cylinders, and the oil cylinders are respectively rotatably installed on both sides of the frame.

[0006] It is further characterized in that:

[0007] Limit switches are respectively installed on both sides of the central support;

[0008] The three rotation centers on the push arm form a triangle.

[0009] The beneficial effects of the present invention are as follows: when the wheel set of the trolley travels to the track, the oil cylinders on both sides respectively push the push arms to rotate, and the push wheels at the top ends of the push arms respectively hold the beam under the trolley from both sides, so as to center and correct the wheel set of the trolley with the track, so as to ensure that the trolley can smoothly enter the track; the limit switch is used to detect the holding position and opening position of the push arm; the three rotation centers on the push arm form a triangle, which is convenient for force application. Brief Description of the Drawings

[0010] Figure 1 It is a schematic diagram of the overall structure of the present invention;

[0011] In the figure: 1 frame; 2 central support; 3 push arm; 4 push wheel; 5 oil cylinder; 6 limit switch. Detailed Description of the Invention

[0012] To deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with the drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0013] The track centering and correcting device includes a frame 1. A central support 2 is installed on the frame 1. Push arms 3 are respectively arranged on both sides of the central support 2. The bottom ends of the push arms 3 are rotatably installed on the frame 1, the top ends are rotatably installed with push wheels 4, and the middle sections are rotatably installed at the end parts of the extending shafts of oil cylinders 5. The oil cylinders 5 are respectively rotatably installed on both sides of the frame 1. Oil cylinders 6 are respectively installed on both sides of the central support 2; the three rotation centers on the push arms 3 form a triangle.

[0014] The beneficial effects of the present invention are as follows: when the wheel set of the trolley travels to the track, the oil cylinders 5 on both sides respectively push the push arms 3 to rotate. The push wheels 4 at the top ends of the push arms 3 respectively hold the beam under the trolley from both sides, so that the wheel set of the trolley is centered and corrected with the track to ensure that the trolley can smoothly enter the track; the oil cylinder 6 is used to detect the holding position and the opening position of the push arm 3; the three rotation centers on the push arm 3 form a triangle, which is convenient for force application.

Claims

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