Description

Technical Field

[0001] The utility model relates to the technical field of road rollers, in particular to a rolling steel wheel for road rollers. Background Art

[0002] As an essential machine for road and site compaction, rollers can effectively compact soft working surfaces to achieve the required density and make the engineering foundation more solid. There are many types of rollers. As a new type of compaction equipment, convex rollers can play a role that cannot be replaced by general light wheel rollers during the construction process due to their special structure. In recent years, convex rollers have been continuously used in construction operations in the fields of transportation, water conservancy and hydropower.

[0003] At present, the rolling steel wheels of static rollers or vibratory rollers widely used in construction have a single function. The steel wheels used are usually smooth wheels or steel wheels with bumps that cannot or are not easy to disassemble. Due to different working scenarios and construction processes, the requirements for steel wheels are different. Therefore, in actual construction, one roller cannot meet the actual needs of changing construction environments and increasing construction requirements. At the same time, the steel wheels of large-tonnage rollers are generally made of rolled plates and welded together. The manufacturing process is complicated, the manufacturing cost is high, and it is not easy to disassemble and replace. The steel wheel assembly of this type of roller has a high manufacturing cost, complex disassembly and assembly, and is difficult to replace. In the actual construction process, frequent transfer of different types of rollers is required, which not only increases the workload of construction personnel, but also brings a series of problems such as extending the construction period and increasing construction costs. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art that it is difficult to disassemble and replace, and to provide a rolling steel wheel for a road roller, which has a reasonable design, a simple and ingenious structure, a low manufacturing cost, and is easy to use. It can not only extend the service life of the rolling steel wheel, but also reduce the cost of use.

[0005] The utility model is realized through the following technical scheme: a rolling steel wheel for a road roller, comprising a steel wheel and a wheel sleeve arranged on the surface of the steel wheel, the wheel sleeve comprising a plurality of arc-shaped plates, a plurality of protrusions are evenly spaced on the surface of the arc-shaped plates, and a detachable protective sleeve is sleeved on the protrusions; the edges on both sides of the arc-shaped plates are staggered tooth structures, and a plurality of arc-shaped plates are assembled together to form a wheel sleeve with a cylindrical structure.

[0006] A further improvement of the utility model is that pin holes corresponding to each other are provided on the protrusion and the protective sleeve, and the protrusion and the protective sleeve are connected by an elastic pin.

[0007] A further improvement of the utility model is that the protrusion and the protective cover are trapezoidal structures corresponding to each other.

[0008] A further improvement of the utility model is that at least two lifting ears are arranged on the surface of the arc-shaped plate.

[0009] A further improvement of the utility model is that a plurality of connecting pieces are arranged at the edges of both sides of the arc-shaped plate, and the plurality of arc-shaped plates are connected by the connecting pieces, bolts and nuts.

[0010] A further improvement of the utility model is that at least three arc-shaped plates are provided.

[0011] From the above technical scheme, it can be seen that the beneficial effects of the utility model are: the convex wheel sleeve of the rolling steel wheel is broken down into parts and adopts an assembled structure, which is convenient for installation and replacement of partial wheel sleeves after wear, and can effectively save costs; at the same time, the protective cover on the convex block is a detachable structure, and the protective cover is a wearing part. Replacing the protective cover in the corresponding position according to the amount of wear can further save the use cost, which not only extends the service life of the rolling steel wheel, but also reduces the use cost.

[0016] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0017] Please refer to the attached Figure 1 and Figure 2, combined with a specific embodiment, it is explained as follows: the utility model is a rolling steel wheel for a road roller, comprising a steel wheel 1 and a wheel sleeve arranged on the surface of the steel wheel, the wheel sleeve comprising three arc-shaped plates 2, a plurality of protrusions 3 are welded on the surface of the arc-shaped plates 2 at even intervals, a detachable protective sleeve 4 is sleeved on the protrusions 3, the protrusions 3 and the protective sleeve 4 are trapezoidal structures corresponding to each other; the edges on both sides of the arc-shaped plates 2 are staggered tooth structures, and the three arc-shaped plates 2 are assembled together to form a wheel sleeve with a cylindrical structure; a plurality of connecting pieces are arranged at the edges on both sides of the arc-shaped plates 2, and the three arc-shaped plates 2 are connected by connecting pieces, bolts 6 and nuts 7.

[0018] The working principle of the utility model is as follows: three arc-shaped plates 2 are assembled to form a wheel sleeve of a cylindrical structure, and the arc-shaped plates 2 are fixed together by means of a staggered tooth structure and bolts 6 and nuts 7. This structure not only ensures that the arc-shaped plates 2 can be firmly sleeved on the steel wheel 1, but also is not easy to slide and fall off along the surface of the steel wheel 1 when the steel wheel 1 vibrates, thereby preventing damage to the wheel sleeve and safety accidents, but also realizes convenient disassembly and assembly of the wheel sleeve, thereby saving costs. At the same time, the protective cover 4 can also effectively protect the protrusion 3, thereby extending the service life of the protrusion 3.

[0019] In one embodiment, pin holes corresponding to each other are provided on the protrusion 3 and the protective cover 4, and the protrusion 3 and the protective cover 4 are connected by an elastic pin 5. The elastic pin 5 has elasticity variation, and when the protective cover 4 needs to be replaced, the protective cover 4 can be removed by knocking out the elastic pin 5 with a tool, which is very convenient, and the elastic pin 5 can also be reused many times.

[0020] In one embodiment, at least two lifting ears 8 are provided on the surface of the arc plate 2. The lifting ears 8 can be used to conveniently lift the arc plate 2 onto the surface of the steel wheel 1 or remove and replace it, greatly reducing the difficulty of installing the wheel sleeve.
