Description

Technical Field

[0001] The utility model relates to the field of road rollers, in particular to a paving road roller for road construction. Background Technique

[0002] The paving road roller in road construction actually covers two different construction machinery, namely a paver and a road roller. The paver is responsible for evenly laying materials such as asphalt mixture and cement concrete on the roadbed according to specific specifications, laying the foundation for subsequent compaction operations. The road roller then uses its own gravity and vibration function to compact the newly laid road surface closely following the paver, so as to improve the density and stability of the road surface. These two kinds of machinery complement each other in road construction, jointly ensuring the efficiency and quality of road construction.

[0003] In the existing paving road roller for road construction, the main way to increase the weight of the road roller is to pour a large amount of concrete in the vehicle to improve the overall weight. However, since the weight of the pressing wheel itself cannot be adjusted, there are still certain defects. For example, the flexibility of the road roller is affected because it cannot flexibly adjust its own weight according to different construction environments and material characteristics, and thus may not achieve the optimal compaction effect. Secondly, the fixed weight may make the road roller appear clumsy and inconvenient during transportation and transfer, especially at the construction site where the working location needs to be frequently changed. Moreover, the non-adjustable weight may cause over-compaction or damage to some fragile or special road surface materials, increasing the construction risk. Finally, this fixed weight design may also accelerate the wear of the components of the road roller and increase the maintenance cost. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a paving road roller for road construction, so as to solve the technical problems that the weight of the pressing wheel of the road roller cannot be adjusted, thereby affecting flexibility, transportation convenience, possibly causing over-compaction damage to road surface materials, and increasing maintenance costs.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A paving road roller for road construction, including a road roller, the road roller includes a vehicle body and a pressing wheel frame. A pressing wheel is installed inside the pressing wheel frame, and the pressing wheel is used to flatten the road surface. Adjusting mechanisms are arranged on both sides of the pressing wheel frame. The adjusting mechanism includes a counterweight frame. A plurality of installation slots are opened at the top of the counterweight frame. Rotating wheels are arranged on both sides of the inner walls of the plurality of installation slots, and the rotating wheels are used to ensure that the weight increasing mechanism can be quickly put in and taken out;

[0006] A rotating shaft is arranged on one side of the plurality of installation slots, and a binding ring is arranged on the other side of the plurality of installation slots. A binding belt is arranged on the rotating shaft and one end of the binding belt is tied to the binding ring, and the binding belt is used to fix a plurality of weight increasing mechanisms.

[0007] By adopting the above technical solutions, the overall design of the roller is compact and practical. In particular, the design of the adjustment mechanism enables the roller to flexibly adjust the counterweight according to different construction requirements. The rotating wheel ensures that the weight adding mechanism can be quickly and conveniently put in and taken out, improving work efficiency.

[0008] Furthermore, a weight adding mechanism is placed inside multiple of the installation grooves. The weight adding mechanism includes counterweight blocks, and a hook ring is arranged on the top of the counterweight blocks.

[0009] By adopting the above technical solutions, the design of the weight adding mechanism enables the roller to increase or decrease the counterweight as needed to adapt to different compaction requirements. The hook ring on the top of the counterweight block facilitates the handling and installation of the counterweight block.

[0010] Furthermore, the hook ring is adapted to the hook of an external crane, and the hook ring can ensure that the external crane hooks out or puts in the weight adding mechanism.

[0011] By adopting the above technical solutions, the loading and unloading of the counterweight block becomes easier and more efficient, can be quickly completed with the help of an external crane, saving labor and time costs.

[0012] Furthermore, the adjustment mechanism and the weight adding mechanism can effectively change the counterweight of the pressing wheel.

[0013] By adopting the above technical solutions, the roller can adapt to more types of construction environments and materials, improving the applicability of the equipment and the construction quality.

[0014] Furthermore, two groups of the adjustment mechanisms are provided, and the two groups of adjustment mechanisms are arranged in a mirror image along the length center line of the pressing wheel.

[0015] By adopting the above technical solutions, the mirror image arrangement of the two groups of adjustment mechanisms ensures the stability and balance of the roller during operation, is beneficial to improving the compaction quality, and reduces the wear of the equipment.

[0016] Furthermore, wheels are arranged on both sides of the vehicle body, and a driver's seat is arranged on the top of the vehicle body.

[0017] By adopting the above technical solutions, the wheels make it convenient for the roller to move and transfer, while the driver's seat provides a comfortable working environment for the operator, facilitating the precise control of the roller.

[0018] Furthermore, a pressing wheel frame is arranged on one side of the vehicle body, and the driver's seat can effectively drive the wheels and control the pressing wheel frame.

[0019] By adopting the above technical solutions, the operation convenience and work efficiency of the roller are improved, enabling the operator to easily control various functions of the roller, ensuring the construction quality and safety.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0028] Next, the embodiments of the utility model will be described according to its overall structure.

[0029] Embodiment 1:

[0030] A paving road roller for road construction, as Figures 1 - 4As shown in the figure, it includes a road roller 1. The road roller 1 includes a vehicle body 101 and a roller frame 104. Inside the roller frame 104, a roller 105 is installed. The roller 105 is used to flatten the road surface. On both sides of the roller frame 104, an adjustment mechanism 2 is provided. The adjustment mechanism 2 includes a counterweight frame 201. At the top of the counterweight frame 201, a plurality of installation slots 205 are provided. On both sides of the inner walls of the plurality of installation slots 205, rotating wheels 206 are provided. The rotating wheels 206 are used to ensure that the weighting mechanism 3 can be quickly inserted and taken out. On one side of the plurality of installation slots 205, a rotating shaft 202 is provided. On the other side of the plurality of installation slots 205, a tying ring 204 is provided. The rotating shaft 202 is provided with a tying band 203 and one end of the tying band 203 is tied to the tying ring 204. The tying band 203 is used to fix the plurality of weighting mechanisms 3. As an overall device, the road roller 1 provides the necessary compaction function for road construction. The vehicle body 101 is the main structure of the road roller, carrying all other components and ensuring its stability and safety. The design of the adjustment mechanism 2 enables the counterweight of the road roller to be flexibly adjusted, increasing the applicability and flexibility of the device.

[0031] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , inside the plurality of installation slots 205, a weighting mechanism 3 is placed. The weighting mechanism 3 includes a counterweight block 301. At the top of the counterweight block 301, a hook ring 302 is provided. The weighting mechanism 3 is stably placed on the counterweight frame 201 through the installation slots 205, increasing the counterweight of the road roller, thereby improving the compaction effect. Moreover, the counterweight block 301 is the main part of the weighting mechanism 3, and its weight can effectively change the pressure of the roller 105 on the road surface.

[0032] Embodiment Two:

[0033] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , the hook ring 302 is adapted to the hook of an external crane, and the hook ring 302 can ensure that the external crane hooks out or inserts the weighting mechanism 3. The hook ring 302 being adapted to the hook of the external crane means that the external crane can be used to quickly and accurately carry and install the weighting mechanism 3, greatly improving the convenience and efficiency of the operation.

[0034] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , the adjustment mechanism 2 and the weighting mechanism 3 can effectively change the counterweight of the roller 105. The cooperation of the adjustment mechanism 2 and the weighting mechanism 3 enables the counterweight of the roller 105 to be precisely adjusted according to construction requirements. This not only helps to improve the compaction effect but also protects fragile or special road surface materials from being damaged by over-compaction.

[0035] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 。 There are two sets of adjusting mechanisms 2, and the two sets of adjusting mechanisms 2 are arranged mirror-symmetrically along the length center line of the pressing wheel 105. The setting of the two sets of adjusting mechanisms 2 and the mirror-symmetric configuration along the length center line of the pressing wheel 105 ensure the stability and balance of the road roller during the compaction process, and further improve the compaction quality and efficiency.

[0036] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 。 On both sides of the vehicle body 101, there are wheels 102, and on the top of the vehicle body 101, there is a driver's seat 103. The wheels 102 enable the road roller to move flexibly at the construction site, improving the mobility of the equipment. Moreover, the driver's seat 103 provides a comfortable working environment for the operator, and at the same time, it is convenient for the operator to control and monitor the working state of the road roller.

[0037] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 。 On one side of the vehicle body 101, there is a pressing wheel frame 104, and the driver's seat 103 can effectively drive the wheels 102 and control the pressing wheel frame 104. The design of the driver's seat 103 enables the operator to conveniently drive the wheels 102 and control the pressing wheel frame 104, thereby precisely controlling the movement and compaction operation of the road roller, and improving the work efficiency and construction quality.

[0038] The implementation principle of the present utility model is as follows: First, it is necessary to check whether all the equipment and mechanisms of the road roller are intact, especially the pressing wheel 105, the adjusting mechanism 2, and the weighting mechanism 3, to ensure that the road roller is in a safe working environment, away from obstacles and personnel, so as to avoid potential safety risks;

[0039] Subsequently, the operator gets on the driver's seat 103, starts the road roller, and drives the wheels 102 to move the road roller to the road surface area that needs to be compacted through the control system on the driver's seat 103. According to the construction requirements and the characteristics of the road surface material, it is decided whether it is necessary to adjust the counterweight of the pressing wheel 105;

[0040] When changing the counterweight, the operator can use an external crane to lift the counterweight block 301 of the weighting mechanism 3 through the hook 302 and quickly place it into the installation groove 205 of the counterweight frame 201. At this time, the rotating wheel 206 will ensure that the weighting mechanism 3 can be smoothly placed in and taken out, and use the strap 203 on the rotating shaft 202 to fix the weighting mechanism 3 in the installation groove 205 to ensure that it will not move during the operation of the road roller;

[0041] After adjusting the counterweight, the operator controls the press wheel frame 104 through the driver's seat 103 to make the press wheel 105 start to roll and compact the road surface. During the compaction process, the operator needs to continuously observe the compaction condition of the road surface and adjust the counterweight of the press wheel 105 according to the actual situation. If it is found that the compaction effect is not good, the counterweight block 301 can be increased or decreased in time through the adjusting mechanism 2.

[0042] Parts not involved in the present utility model are the same as or can be implemented by using the prior art, and will not be elaborated here.

The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can, without departing from the principle and purpose of the present utility model, make modifications, substitutions and variations that do not make creative contributions to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
