Description

Technical Field

[0001] The utility model relates to the technical field of roller compactors, in particular to a roller with replaceable pressing teeth for a roller compactor. Background Technique

[0002] A roller compactor, also known as a soil compactor, is a road construction equipment, mainly applicable to compact sandy, semi-viscous and viscous soils, subgrade stabilized soils and asphalt concrete pavement layers. During its operation, the road surface is mainly compacted by the roller. To prevent the roller from slipping on the ground, an anti-slip layer with pressing teeth is generally provided on the outside of the roller.

[0003] Chinese Patent Authorization Publication No. CN 219297893 U discloses a roller for a roller compactor, which includes two mounting frames and a roller main body. The roller main body is arranged in the two mounting frames, and the tops of the two mounting frames are fixedly connected with the same protective shell. A scraping component is arranged on the protective shell. The scraping component includes a frame and a screw rod. Through the wear-resistant layer, the material of which is high manganese steel, through the scraping plate, the cleaning mechanism and the dust suction mechanism, the soil and sand on the roller main body can be effectively removed, improving the compaction effect of the roller compactor. The above existing technical solutions have the following deficiencies: in the structure of this roller, the cleaning of the roller is mainly achieved by the scraping plate and the cleaning and dust suction methods. However, due to the unevenness of the roller surface, the scraping effect of the scraping plate will be reduced. And as the use time increases, due to serious wear of the pressing teeth, generally the whole roller needs to be disassembled. Its disassembly operation is inconvenient, and at the same time the replacement cost is relatively high. Therefore, there is a certain room for improvement. Content of the Utility Model

Specific embodiments

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 4 , an embodiment provided by the present utility model: a roller of a road roller with replaceable pressing teeth, including a roller 1 of the road roller, and a plurality of pressing tooth assemblies 2 are uniformly arranged along the radial direction on the outer side of the roller 1 of the road roller;

[0023] The pressing tooth assembly 2 includes a steel wire 201, and pressing teeth 202 are uniformly sleeved outside the steel wire 201. Welding pieces 203 are welded on both sides of the pressing teeth 202, and the inside of the welding pieces 203 is welded to the outer wall of the steel wire 201;

[0024] The bottom end of the pressing tooth 202 is connected to the top end of the limiting block 8, and the two are of an integral structure;

[0025] One end of the steel wire 201 is welded to one end of the connecting ring 9. The outer diameter of the steel wire 201 is adapted to the inner diameter of the clamping groove 5, and the steel wire 201 is clamped and connected to the locking rod 4 through the cooperation of the clamping groove 5;

[0026] Specifically, as Figure 1 , Figure 4As shown in the figure, during use, the steel wire 201 is used to limit the pressing teeth 202, and in combination with the welding piece 203, the fixing of the pressing teeth 202 and the steel wire 201 is achieved to prevent the random movement of the pressing teeth 202. By installing the steel wire 201 and the roller of the road roller 1, the separate disassembly and replacement of the pressing teeth 202 can be realized.

[0027] Moreover, a plurality of limiting blocks 8 are evenly installed on the inner side of the pressing tooth assembly 2 close to the roller of the road roller 1, and a plurality of limiting grooves 7 are evenly formed on the outer side of the roller of the road roller 1.

[0028] There are multiple groups of limiting grooves 7, and each group has multiple. The quantity difference between adjacent limiting grooves 7 is one. Each group of limiting grooves 7, the fixing rods 6, and the positioning grooves 3 are collinear along the axial direction of the roller of the road roller 1.

[0029] The bottom end of the limiting block 8 extends into the interior of the limiting groove 7 and abuts against the inner wall of the limiting groove 7. One end of the roller of the road roller 1 is evenly installed with fixing rods 6.

[0030] The fixing rod 6 is of an L-shaped structure, and the L-shaped bend of the fixing rod 6 faces the axial center direction of the roller of the road roller 1. The fixing rods 6 and the positioning grooves 3 are evenly distributed in an annular shape at both ends of the roller of the road roller 1.

[0031] Specifically, as Figure 2 shown, during use, under the action of the fixing rod 6, one end of the steel wire 201 can be fixed, so that the steel wire 201 can be axially distributed on the roller of the road roller 1.

[0032] Moreover, a connecting ring 9 is sleeved inside each fixing rod 6. One side of each connecting ring 9 is welded to one end of the corresponding pressing tooth assembly 2. A positioning groove 3 is evenly formed at the other end of the roller of the road roller 1, and a locking rod 4 penetrates through the interior of each positioning groove 3.

[0033] The locking rod 4 is threadedly connected to the positioning groove 3. After the steel wire 201 is clamped into the interior of the clamping groove 5, through the screwing action of the locking rod 4, the tensioning of the steel wire 201 is realized.

[0034] A clamping groove 5 is formed at the outer end of each locking rod 4, and the clamping groove 5 is engaged and wound with one end of the pressing tooth assembly 2 far from the connecting ring 9.

[0035] Specifically, as Figure 1 、 Figure 3 shown, during use, the locking rod 4 drives the clamping groove 5 to rotate, thereby winding one end of the steel wire 201. In combination with the threaded connection function of the positioning groove 3, the tensioning and fixing of the steel wire 201 are realized.

[0036] Working principle: When the utility model is in use, first, the connecting ring 9 is sleeved outside the fixing rod 6, and then the steel wire 201 is tightened, so that the steel wire 201 is tensioned along the axial direction of the roller 1 of the road roller, and the pressing teeth 202 are located above the corresponding limiting grooves 7. Press the pressing teeth 202 downward so that the limiting blocks 8 are correspondingly inserted into the internal of the limiting grooves 7 to realize the preliminary fixation of the pressing teeth 202;

[0037] Secondly, pull the other end of the steel wire 201 to the other side of the roller 1 of the road roller, and press and snap the steel wire 201 into the outer end of the locking rod 4 through the card slot 5 to realize the preliminary fixation between the steel wire 201 and the roller 1 of the road roller. Then, use a tool to rotate the locking rod 4 so that the locking rod 4 is screwed into the internal of the positioning groove 3. As the screwing deepens, the locking rod 4 drives the steel wire 201 to wind up, thereby tensioning the steel wire 201 to prevent the steel wire 201 from loosening and spreading, and then realizing the installation and fixation of the pressing teeth 202, and this fixing method is detachable.
