Description

Technical Field

[0001] This utility model belongs to the field of vibratory rollers, specifically relating to a vibratory roller wheel protrusion wheel skin. Background Technology

[0002] Vibratory rollers are engineering machines that use their own weight and vibration to compact various building and road construction materials. They are widely used in the construction of highways, railways, airports and other projects.

[0003] Currently, vibratory rollers mainly consist of rollers, a vibration excitation mechanism, a vibration damping system, and a traveling mechanism. Among these, the rollers, as the core component of the vibratory roller, mostly adopt a smooth wheel structure. Therefore, they can only perform compaction operations on relatively flat road surfaces. When encountering different types of soil, they cannot achieve the goal of both compacting and breaking up the soil layer, especially when compacting cohesive soils and frozen soils, where the compaction effect is often unsatisfactory. Therefore, existing vibratory rollers typically employ the measure of adding protruding wheel skins to the outer circumference of the rollers when compacting special types of soil to improve the compaction effect of cohesive soils and frozen soils.

[0004] However, the existing bump wheel structure still has some defects in practical applications: the bump wheel of the existing vibratory roller is often equipped with a split structure for easy disassembly and assembly, and the compaction effect is optimized by setting the bumps of each ring in a staggered manner; however, since the joint of each arc shell in the existing bump wheel is often a straight edge structure, the number of split bumps set at the joint of adjacent arc shells is small, which can easily lead to the problem of low connection strength of the entire bump wheel, and problems such as loosening and uneven gaps are likely to occur in actual compaction operations, thus affecting the overall compaction quality. Utility Model Content

[0005] The purpose of this invention is to address the problems of low connection strength and poor compaction effect of existing vibratory rollers during use, and to propose and design a vibratory roller wheel protrusion wheel skin to overcome the above problems, thereby ensuring that the vibratory roller has stable and powerful crushing and compaction capabilities.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a vibratory roller wheel protrusion wheel skin, comprising at least two arc-shaped wheel skins connected end to end in sequence, wherein at least two layers of fixed tooth blocks are spaced apart along the axial direction on the outer surface of the arc-shaped wheel skin, and any two adjacent layers of fixed tooth blocks are staggered; the edge on the arc-shaped wheel skin used to connect with the adjacent arc-shaped wheel skin is a curved edge, and at least one layer of fixed tooth blocks in any two adjacent layers has connecting tooth blocks at both ends at the curved edge, and the connecting tooth blocks are detachably connected to the corresponding connecting tooth blocks on the adjacent arc-shaped wheel skin by fasteners. Because this utility model adopts a unique tooth block arrangement structure, it can not only ensure that there are no dead corners during the compaction process through the staggered arrangement of fixed tooth blocks, thus adapting to various compaction conditions; it can also ensure that there is sufficient connection structure between adjacent arc-shaped wheel skins and no large gaps between tooth blocks through the curved edge and the connecting tooth blocks set at the curved edge, thereby avoiding problems such as loosening and uneven gaps in the entire roller protrusion wheel skin during actual operation, so as to ensure the overall compaction quality.

[0007] Furthermore, any two layers of fixed toothed blocks on the same arc-shaped wheel skin are staggered to ensure that the entire roller protrusion wheel skin has no dead angles during actual construction and can adapt to various compaction conditions.

[0008] Furthermore, connecting tooth blocks are provided at each turning point of the curved edge. The connecting tooth blocks are located at both ends of the corresponding layer of fixed tooth blocks and can be detachably connected to the connecting tooth blocks provided on the adjacent arc-shaped wheel skin by bolts and nuts.

[0009] Furthermore, the curved edges are sequentially set as hypotenuse one, hypotenuse two, and hypotenuse three. The lower end of hypotenuse two coincides with the lower end of hypotenuse one, and the upper end of hypotenuse two coincides with the upper end of hypotenuse three, thus forming a structure similar to a "Z" shape. This ensures that enough connecting teeth can be set between adjacent arc-shaped wheel skins, and that there is sufficient connection strength.

[0010] Furthermore, ten layers of fixed tooth blocks are arranged at axial intervals on the outer surface of the arc-shaped wheel skin. All the fixed tooth blocks are numbered sequentially along the axial direction. Connecting tooth blocks are provided at both ends of the first, third, fifth, sixth, eighth, and tenth fixed tooth blocks, and the fifth and sixth fixed tooth blocks are located at both ends of the second hypotenuse.

[0011] Furthermore, the fixed tooth block has a hollow structure, and the wall thickness of the fixed tooth block is preferably 10mm.

[0012] Furthermore, a protective groove is provided at the end of the connecting tooth block away from the connecting tooth block it is connected to. A connecting through hole runs through the bottom of the protective groove, and the corresponding bolt is installed through the connecting through hole. The protective groove protects the bolts and nuts connected to it, preventing them from being damaged during the compaction operation.

[0013] Furthermore, a wear-resistant layer is provided at the top of the fixed tooth block and / or the top of the connecting tooth block, and the wear-resistant layer is preferably welded by D-65 wear-resistant welding rod to enhance the wear resistance of the fixed tooth block and / or the connecting tooth block.

[0014] Furthermore, each arc-shaped wheel skin has a lifting plate on its outer surface, which facilitates the operator to lift the arc-shaped wheel skin during the assembly process of the entire roller protrusion wheel skin.

[0015] Furthermore, the two ends of the lifting plate are welded and fixed to the corresponding two fixed tooth blocks, and the position of the lifting plate on each arc-shaped wheel skin is preferably set to the same position to facilitate the lifting of the arc-shaped wheel skin.

[0016] As can be seen from the above technical solutions, this utility model has the following advantages:

[0017] 1. Because this utility model sets up the fixed tooth blocks in staggered layers and adopts a trapezoidal structure for each fixed tooth block, it can ensure that there are no dead corners in the entire roller protrusion wheel skin during the compaction operation, so as to adapt to various compaction conditions; moreover, based on the tooth block arrangement structure, this utility model can have a strong climbing ability to meet the climbing requirements of large tonnage road rollers and realize the compaction of cohesive soil.

[0018] 2. Because the edge of the arc-shaped wheel skin is designed as a curved edge, the curved edge and the connecting tooth block set at the curved edge can ensure that there is a sufficient connection structure between adjacent arc-shaped wheel skins, but there is no large gap between the tooth blocks. This avoids problems such as loosening and uneven gaps in the entire roller protrusion wheel skin during actual operation, so as to ensure the overall compaction quality.

[0019] 3. Because the present invention has a protective groove on the end of the connecting tooth block away from the connecting tooth block it is connected to, the bolts and nuts connected to it can be protected by the protective groove to prevent them from being damaged during the compaction operation.

[0020] 4. Since this utility model has a lifting plate on the outer surface of each arc-shaped wheel skin, the operator can easily lift the arc-shaped wheel skin during the assembly process of the entire roller protrusion wheel skin through the lifting plate. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 5 As shown, this utility model provides a vibratory roller protrusion wheel skin, which includes at least two arc-shaped wheel skins 1 connected end to end in sequence. The arc-shaped wheel skins 1 are made of 6mm thick rolled steel plates, and preferably there are three arc-shaped wheel skins 1. The shape of the arc-shaped wheel skins 1 after being connected is circular.

[0030] Specifically, such as Figure 3 As shown, the edge on the arc-shaped wheel skin 1 used to connect with the adjacent arc-shaped wheel skin 1 is a curved edge. The curved edge is set as a first hypotenuse, a second hypotenuse, and a third hypotenuse in sequence. The lower end of the second hypotenuse coincides with the lower end of the first hypotenuse, and the upper end of the second hypotenuse coincides with the upper end of the third hypotenuse, thus forming a structure similar to a "Z".

[0031] The outer surface of the arc-shaped wheel skin 1 is provided with 10 layers of staggered fixed tooth blocks 2 along the axial direction. The outermost fixed tooth block 2 is 40mm away from the edge of the arc-shaped wheel skin 1. The distance between adjacent fixed tooth blocks 2 is 130mm. Any two layers of fixed tooth blocks 2 are staggered. A lifting plate 4 is welded between the corresponding two fixed tooth blocks 2. Meanwhile, to facilitate the description of each fixed tooth block 2 layer, this embodiment also sequentially numbers the 10 layers of fixed tooth blocks 2 arranged axially at intervals on the outer surface of the arc-shaped wheel skin 1. Among them, the second, fourth, seventh, and ninth layers are each evenly provided with 5 fixed tooth blocks 2, the fifth and sixth layers are located at both ends of the second inclined side, and the first, third, fifth, sixth, eighth, and tenth layers are each evenly provided with 3 fixed tooth blocks 2. Connecting tooth blocks 3 are provided at both ends of the first, third, fifth, sixth, eighth, and tenth layers at the curved edge. The connecting tooth blocks 3 are detachably connected to the corresponding connecting tooth blocks 3 on the adjacent arc-shaped wheel skin 1 by fasteners 5.

[0032] Moreover, as a preferred option, such as Figure 2 , Figure 5 As shown, in this embodiment, the fastener 5 is preferably a combination of M22 high-strength bolt and nut. In this embodiment, a protective groove 6 is provided on the end of the connecting tooth block 3 away from the connecting tooth block 3 it is connected to. The bottom of the protective groove 6 is penetrated by a connecting through hole 7, so that the corresponding bolt can be installed through the connecting through hole 7. The protective groove 6 protects the bolt and nut connected to it, preventing them from being damaged during the compaction operation.

[0033] like Figure 4 As shown, the fixed tooth block 2 is trapezoidal in shape, and its external dimensions are: upper length of 100mm, lower arc length of 200mm, thickness of 60mm, and tooth height of 100mm. The interior of the fixed tooth block 2 preferably adopts a hollow structure with a wall thickness of 10mm. The top of the fixed tooth block 2 and / or the top of the connecting tooth block 3 are provided with a wear-resistant layer, which is preferably welded by D-65 wear-resistant welding rod to enhance the wear resistance of the fixed tooth block 2 and / or the connecting tooth block 3.

[0034] At this point, because the present invention adopts a unique tooth block arrangement structure, it can not only ensure that there are no dead corners in the compaction operation through the staggered fixed tooth block structure, so as to adapt to various compaction conditions; it can also ensure that there is a sufficient connection structure between adjacent arc-shaped wheel skins 1 through the curved edge and the connecting tooth block 3 set at the curved edge, while there is no large gap between the tooth blocks, thereby avoiding problems such as loosening and uneven gaps in the entire roller protrusion wheel skin during actual operation, so as to ensure the overall compaction quality.
