AI Technical Summary
Existing tracked tractors cannot adjust track spacing and limits when transporting long objects that are thick or of varying widths, resulting in unstable transport.
An adjustable-width tracked traction machine was designed. The track spacing is adjusted by an adjustment mechanism, and the limiting mechanism limits the movement according to the width of the object to ensure traction stability.
It enables stable transportation of objects of varying thicknesses and widths, preventing track slippage and object deviation, thus improving transportation stability and safety.

Description
Technical Field
[0001] The utility model relates to the technical field of traction machine equipment, in particular to a crawler-type traction machine with adjustable width. Background Art
[0002] The crawler tractor uses the upper and lower rows of compression cylinders to push the crawler to apply pressure to the cable, thereby moving long linear objects forward in a balanced manner. It is an ideal traction equipment for object traction. When transporting long objects on the production line, a crawler tractor with adjustable width is required.
[0003] According to the description of a crawler tractor disclosed in the patent website (authorization announcement number: CN 208413470 U), "the utility model discloses a crawler tractor, including a tractor body, the tractor body includes a box and a crawler, the crawler includes an upper crawler and a lower crawler, a lower block is provided on one side of the box, a cutter is provided on the lower block, an upper block is provided on the top of the lower block, a switch is provided on the top of the upper block, an air pipe is provided on the box, an air intake valve is provided at one end of the air pipe, an exhaust valve is provided at the other end of the air pipe, an air distributor valve and a pressure gauge are provided on the top of the box, the air distributor valve is provided on one side of the pressure gauge, the air distributor valve is provided on the air pipe, a pressure plate is provided on the inner side of the upper crawler, a cylinder is provided at the bottom of the pressure plate, a slide plate is provided at the bottom of the cylinder, a motor is provided on one side of the upper crawler, the crawler tractor is reasonably designed, convenient to use, and suitable for object traction."
[0004] In view of the above description, the applicant believes that there are the following problems:
[0005] During use, the utility model controls the clamping force of the crawler on the supported object through air pressure, the slide plate and the roller, thereby effectively reducing the friction force of the pressurizing component on the crawler, and the lower block and the upper block can effectively control the moving distance of the towed object. However, in actual use, the distance between the upper crawler and the lower crawler is fixed. When thicker long objects need to be transported, the thicker long objects cannot be put between the upper crawler and the lower crawler, making it impossible to transport them.

[0038] In actual operation, when the device is used, the starting motor A612 drives the threaded rod 613 to rotate.
