[0001] The present invention relates to the field of pipe processing equipment, and in particular to a traction machine crawler adjustment device. Background Art

[0002] In the production of PPR pipes, pipe rotation has always been a significant factor affecting production efficiency and product quality. Due to concentricity deviation of the hauling machine tracks during operation, the pipes frequently rotate during hauling, resulting in inaccurate inkjet printing and high scrap rates. This not only increases production costs but also affects product competitiveness. Traditional solutions typically rely on regular maintenance and replacement of the tracks to maintain concentricity. However, this approach is not only time-consuming and labor-intensive, but also fails to fundamentally address the concentricity deviation caused by track wear.

[0003] Therefore, there is an urgent need for a technical solution that can adjust the concentricity of the track in real time during the operation of the tractor to ensure that the upper and lower tracks remain parallel after wear, thereby effectively preventing the pipe from rotating.

[0022] like Figure 1 As shown, in one embodiment, the present invention discloses a device for adjusting the upper crawler of a dual-track tractor, the device mainly comprising an upper crawler height adjustment mechanism and an upper crawler end swing mechanism. The upper crawler height adjustment mechanism controls the connection to the upper crawler and can longitudinally adjust the distance between the upper crawler and the lower crawler, so that the tractor can adapt to pipes of different sizes. The upper crawler end swing mechanism controls the pipe inlet end connected to the upper crawler and can adjust the pipe inlet end horizontally left and right in real time according to the pipe traction working conditions, thereby maintaining the concentricity of the pipe and effectively preventing it from rotating between the crawlers.

[0023] Specifically, the upper track height adjustment mechanism includes a cylinder 1 and a guide rod slider assembly 2. The cylinder 1 is vertically mounted within the tractor frame, located to one side of the center of the upper track. A connecting block 3 is mounted on the telescopic end of the cylinder and is fixedly connected to the upper track support plate on that side via the connecting block 3. The guide rod slider assembly 2 is positioned near the pipe outlet end of the upper track and is fixedly connected to the upper track support plate via its slider. The height adjustment mechanism controls the support plate by retracting and retracting the cylinder, thereby moving the entire upper track up and down, adjusting the gap between the upper track and the lower track.

[0024] The upper track end swing mechanism includes a rotating rod 4, a handle 5, a fixed block 6, and a lifting assembly. The fixed blocks 6 are equipped with bearings and are symmetrically mounted on either side of the top of the tractor frame.
