Description

Technical Field

[0001] The utility model relates to the technical field of crawler traction machines, in particular to a row of rollers for crawler traction machines. Background Art

[0002] The row roller of crawler tractor is one of the key components used to support and guide the crawler track. The row roller is usually a group of rollers arranged in parallel, installed at the bottom or side of the crawler tractor, and in direct contact with the crawler track.

[0003] As the crawler tractor is used, the roller will constantly contact and rotate with the crawler, thus experiencing wear. Long-term use and harsh working environment will accelerate the wear process of the roller. When the surface of the roller is worn to a certain extent, its shape and size will change, resulting in poor fit with the crawler, reducing traction efficiency, and may even cause malfunctions. Therefore, after the roller has been used for a long time, it is necessary to replace the roller. However, the replacement procedures of the rollers currently on the market are relatively cumbersome and the replacement time is long, which wastes the operator's time and is not conducive to user use.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-7 A row of rollers for crawler traction machines, including a support plate 1, two support plates 1 are arranged in parallel, a plurality of rotating shafts 2 are rotatably arranged between the support plates 1 on both sides, a mounting seat 3 is fixedly arranged on the outer side of the rotating shaft 2, a plurality of mounting parts 32 are fixedly arranged on the mounting seat 3, and an outer roller 4 is sleeved on the outer side of the mounting seat 3. A second outer plate 5 is mounted on the rotating shaft 2 on one side of the outer roller 4, a limiting ring 6 is arranged on the outer side of the second outer plate 5, an inner thread 61 is arranged on the inner wall of the limiting ring 6, and an outer thread 21 is adapted to correspond to the inner thread 61 at one end of the rotating shaft 2. It is worth noting that the rotating shaft 2 is located between the support plates 1 on both sides and rotates, the rotating shaft 2 is driven by an external driving mechanism, and the outer side of the outer roller 4 can be freely customized with patterns. These are all prior arts, which do not belong to the technical problems to be solved in the present technical solution, and are common knowledge well known to those skilled in the art, so they are not elaborated in the present utility model.

[0023] Among them, a first outer plate 31 is fixedly arranged on one side of the rotating shaft 2 located at the mounting seat 3, and a reinforcing groove 33 is provided on the side of the mounting member 32 away from the first outer plate 31. The diameter of the second outer plate 5 is the same as that of the first outer plate 31, and a plurality of reinforcing columns 51 are fixedly arranged on the side of the second outer plate 5 facing the first outer plate 31, and the reinforcing columns 51 are all adapted to the reinforcing groove 33. Through the arrangement of the first outer plate 31 and the second outer plate 5, the two ends of the outer drum 4 can be limited, thereby realizing the installation of the outer drum 4.

[0024] The outer drum 4 has a mounting groove 41 extending therethrough, and the mounting groove 41 is adapted to the mounting seat 3 and the mounting member 32. By setting the mounting member 32, the outer drum 4 can be fixedly sleeved on the outer side of the mounting seat 3, so that the outer drum 4 and the rotating shaft 2 rotate synchronously.

[0025] A through hole is formed in the middle of the second outer plate 5, the diameter of which is larger than the diameter of the external thread 21, and an anti-slip member 52 is fixedly provided on the other side of the second outer plate 5. An anti-slip cavity 62 is formed inwardly on the side of the stop ring 6 facing the second outer plate 5, and the anti-slip cavity 62 is adapted to the anti-slip member 52. By providing the stop ring 6, the second outer plate 5 can be clamped, thereby achieving the installation of the outer drum 4.

[0026] In this embodiment, when the user needs to install the outer drum 4, the outer drum 4 only needs to be sleeved on the outer side of the mounting seat 3, and the outer drum 4 can be fixed by setting the mounting member 32. When one end of the outer drum 4 contacts the first outer plate 31, the user can assemble the second outer plate 5 on the other end of the outer drum 4, and insert the reinforcement column 51 on the second outer plate 5 into the reinforcement groove 33 in the mounting member 32.

[0027] Furthermore, after the second outer plate 5 is installed, the user can install the stop ring 6 on the rotating shaft 2 through the adaptation setting between the external thread 21 and the internal thread 61, so that the second outer plate 5 can be clamped by the stop ring 6. And when the stop ring 6 is assembled, the anti-slip part 52 is located in the anti-slip cavity 62, so that the internal thread 61 on the stop ring 6 is not easy to loosen with the external thread 21 on the rotating shaft 2 through the adaptation setting between the anti-slip part 52 and the anti-slip cavity 62. When the user needs to remove the outer drum 4, it only needs to be removed in the reverse direction according to the above assembly method.

[0028] In the utility model, by setting the mounting member 32, the outer drum 4 can be fixedly assembled on the outer side of the mounting seat 3, and by setting the first outer plate 31 and the second outer plate 5, the two ends of the outer drum 4 can be clamped, and by setting the limiting ring 6, the second outer plate 5 can be clamped, thereby achieving fixed assembly of the outer drum 4. This assembly method is fast and convenient, and the user only needs to replace the worn outer drum 4, which is convenient for user use.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
