Description

Technical Field

[0001] This utility model belongs to the field of road roller technology and relates to a road roller that is easy to adjust the steering angle range. Background Technology

[0002] A road roller is a heavy-duty engineering machine that uses its own weight and the impact force generated by vibration to compact materials such as soil, gravel, asphalt, and concrete in engineering projects such as roads, embankments, airports, and building foundations. Its main purpose is to increase road density, enhance stability, and reduce road permeability.

[0003] The following technical problems were found in the existing technology: In the existing technology, when the road roller is used, when it encounters narrow bends, ditch edges or large obstacles, the workers often keep a certain distance from the obstacles in order to avoid collisions. This results in areas that cannot be compacted, which require manual remediation, increasing the cost of use and the construction period. Utility Model Content

[0004] The technical problem this utility model aims to solve is that, in the prior art, when a road roller encounters narrow bends, ditch edges, or large obstacles, workers often maintain a certain distance from the obstacles to avoid collisions. This results in areas that cannot be compacted, requiring subsequent manual remediation, which increases the cost and construction period.

[0005] The present invention describes a road roller that is easy to adjust the steering angle range, comprising a drive body, a front roller disposed on the outside of the drive body, and a water tank assembly disposed on the top of the outside of the front roller.

[0006] A connecting component is located at the bottom outer side of the drive body. The drive body is connected to the front pressure roller through the connecting component. The connecting component includes an angle adjustment mechanism and a fixing mechanism.

[0007] The water tank assembly includes an installation groove, a support plate, and a water tank. The installation groove is provided on one side of the front roller, and the support plates are installed on both sides inside the front roller. The water tank is provided inside the installation groove.

[0008] The connecting assembly includes a fixing plate A, a connecting block, and a fixing plate B. Two sets of fixing plates A are fixedly connected to one side of the drive body. A connecting block is fixedly connected to the outside of the fixing plate A. A fixing plate B is fixedly connected to the outside of the drive body near the fixing plate A.

[0009] The angle adjustment mechanism includes a hinge frame A, a hinge frame B, a pin, a hydraulic adjustment rod, and a hinge block. The hinge frame A is fixedly connected to the outside of the fixed plate B. The hinge frame B is hinged to the outside of the hinge frame A. The pin is slidably connected inside the hinge frame A. The hydraulic adjustment rod is hinged to the middle of the connecting block. The hinge block is fixedly connected to the outside of the hinge frame B. The end of the hydraulic adjustment rod away from the connecting block is hinged to the hinge block.

[0010] The fixing mechanism includes a mating groove, a water inlet, fixing screws, and mounting screw holes. The mating groove is provided on one side of the water tank, the water inlet is provided on the top of the outer side of the water tank, the fixing screw is provided on the outer side of the water tank away from the mating groove, and the mounting screw holes are provided on the outer side of the support plate.

[0011] The water tank is made of stainless steel inside and coated with a layer of polyethylene on the outside.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By using the connecting components, when the front pressure roller is compacting the working area, the operator can adjust the angle of the front pressure roller by controlling the extension and retraction of the hydraulic adjustment rod when facing narrow bends, ditch edges, or large obstacles. This allows the front pressure roller to be as close as possible to the obstacle or ditch edge, reducing the gap between the front pressure roller and the obstacle, reducing the workload of subsequent operators in treating uncompacted areas, and further improving the practicality and reliability of the device. The matching groove on the outside of the water tank and the position of the water tank make the front pressure roller more convenient to use, increasing the practicality of the device.

[0013] By using a composite material for the water tank—an inner stainless steel tank and an outer polyethylene tank—the inner stainless steel reduces the likelihood of corrosion and rust buildup that could clog the water pump or nozzles, extending the tank's lifespan. Meanwhile, the outer polyethylene is hydrophobic and easy to clean, while also protecting the tank from external rainwater, salt spray, and sediment corrosion. Its excellent elasticity and toughness further reduce the possibility of damage to the tank surface from flying debris, thus improving the device's practicality. Attached Figure Description

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] Example 1

[0032] like Figure 1 - Figure 11 As shown, a road roller for easy adjustment of steering angle range includes a drive body 1, a front roller 2 is provided on the outside of the drive body 1, and a water tank assembly is provided on the top of the outside of the front roller 2.

[0033] A connecting component is located at the bottom outer side of the drive body 1. The drive body 1 is connected to the front pressure roller 2 through the connecting component. The connecting component includes an angle adjustment mechanism and a fixing mechanism.

[0034] The water tank assembly includes an installation groove 3, a support plate 4, and a water tank 5. The installation groove 3 is provided on one side of the front road roller 2, and the support plate 4 is installed on both sides inside the front road roller 2. The water tank 5 is provided inside the installation groove 3.

[0035] The connecting assembly includes a fixing plate A6, a connecting block 7, and a fixing plate B8. Two sets of fixing plates A6 are fixedly connected to one side of the drive body 1. A connecting block 7 is fixedly connected to the outside of the fixing plate A6. A fixing plate B8 is fixedly connected to the outside of the drive body 1 near the fixing plate A6.

[0036] The angle adjustment mechanism includes a hinge frame A9, a hinge frame B10, a pin 11, a hydraulic adjustment rod 12, and a hinge block 13. The hinge frame A9 is fixedly connected to the outside of the fixed plate B8. The hinge frame B10 is hinged to one side of the outside of the hinge frame A9. The pin 11 is slidably connected inside the hinge frame A9. The hydraulic adjustment rod 12 is hinged to the middle of the connecting block 7. The hinge block 13 is fixedly connected to the outside of the hinge frame B10. The end of the hydraulic adjustment rod 12 away from the connecting block 7 is hinged to the hinge block 13.

[0037] The fixing mechanism includes a mating groove 14, a water inlet 15, a fixing screw 16, and a mounting screw hole 17. The mating groove 14 is provided on one side of the water tank 5, the water inlet 15 is provided on the top of the outer side of the water tank 5, the fixing screw 16 is provided on the outer side of the water tank 5 away from the mating groove 14, and the mounting screw hole 17 is provided on the outer side of the support plate 4.

[0038] During operation, the fixing plate A6 is first fixed to the outside of the drive body 1 by welding or bolting. The specific connection method is not limited in this technical solution. The fixing plate B8 covers the outside of the fixing plate A6 and is fixedly connected to the drive body 1. Then, the hinge frame A9 is fixed to the outside of the fixing plate B8. Then, the hinge frame B10 is fixedly connected to the outside of the front roller 2, so that when the front roller 2 is close to the drive body 1, the position of the hinge frame B10 can be close to the hinge frame A9. When the hinge frame B10 and the hinge frame A9 are brought close together, the hydraulic adjusting rod 12 is connected to the connecting block 7. The other end of the hydraulic adjusting rod 12 is hinged to the hinge block 13 of the hinge frame B10. Then, a pin is used. 11. Limit the articulation frame A9 and articulation frame B10 so that articulation frame B10 can be connected to articulation frame A9 while also rotating. By controlling the extension and retraction of hydraulic adjustment rod 12, articulation frame B10 can be angled around articulation frame A9 with pin 11 as the center. Furthermore, articulation frame B10 is fixedly connected to front road roller 2. When hydraulic adjustment rod 12 drives articulation frame B10 to rotate, articulation frame B10 moves front road roller 2 to adjust its angle. This allows for angle adjustment when using drive body 1 to compact the ground, enabling drive body 1 to more flexibly change the forward path of the device when facing more complex tasks, further increasing the practicality and flexibility of the device.

[0039] When using the front roller 2 to compact the working area, the water tank 5 is fixed to the mounting groove 3 via the support plate 4. The mounting groove 3 is located above the front roller 2 and close to the drive body 1. The water stored inside the water tank 5 can wet the surface of the front roller 2 while it is working, and at the same time, the water seeps into the soil. The soil containing an appropriate amount of moisture will be easier to compact. The water tank 5 is located above the front roller 2, so that the water tank 5 can wet the front roller 2. This design makes it more convenient to clean and cool the front roller 2. The water tank 5 is located on the side of the front roller 2 close to the drive body 1. When the front roller 2 is working, if it encounters hard stones and splashes, the front roller 2 will block the stones from hitting the water tank 5 and causing damage. When the water tank 5 is full of water, it can act as a counterweight for the front roller 2, increasing its overall weight and static pressure, which helps to improve the compaction effect.

[0040] The water tank 5 has a groove 14 on its exterior, which transforms the surface of the water tank 5 from a two-dimensional plane into a three-dimensional reinforced structure. This can effectively resist deformation, increase the bending and deformation resistance of the inner wall of the water tank 5, and increase the service life of the water tank 5. At the same time, it increases the outer surface area of ​​the water tank 5, enhances the heat exchange between the water tank 5 and the outside world, and can dissipate the heat generated by the front roller 2 during operation, indirectly improving the cooling efficiency of the engine. The uneven surface can also provide footholds for maintenance personnel when inspecting the water tank 5, improving the safety of the operation.

[0041] The shape of the support plate 4 matches the water tank 5. Mounting screw holes 17 are provided on the outer side of the support plate 4, raising the mounting screw holes 17 to ensure a tighter connection between the support plate 4 and the water tank 5. During use, the front roller 2 generates continuous and high-intensity vibrations. If there is a gap between the support plate 4 and the water tank 5, high-frequency vibrations will occur, damaging the structure of both the water tank 5 and the support plate 4 and reducing the lifespan of the device. Therefore, the shape of the support plate 4 is designed to fit snugly against the water tank 5, reducing the gap between them and further mitigating the impact of high-frequency vibrations on the device's lifespan. Water is injected into the water tank 5 through the water inlet 15, and the support plate 4 is then connected to the water tank 5 using fixing screws 16.

[0042] By using the connecting components, when the front roller 2 is compacting the work area, the operator can adjust the angle of the front roller 2 by controlling the extension and retraction of the hydraulic adjusting rod 12 when facing narrow bends, ditch edges, or large obstacles. This allows the front roller 2 to be as close as possible to the obstacle or ditch edge, reducing the gap between the front roller 2 and the obstacle. This reduces the workload of subsequent operators in treating uncompacted areas, further improving the practicality and reliability of the device. The position of the mating groove 14 on the outside of the water tank 5 and the water tank 5 makes the front roller 2 more convenient to use, increasing the practicality of the device.

[0043] Example 2

[0044] like Figure 1 - Figure 3 As shown,

[0045] The interior of the water tank 5 is made of stainless steel, and the exterior is coated with a layer of polyethylene.

[0046] By using a composite material of stainless steel inside and polyethylene outside, the stainless steel inside reduces the possibility of water corrosion causing rust and clogging of the water pump or nozzle, thus extending the service life of the water tank. Meanwhile, the outer polyethylene is hydrophobic and easy to clean, and it also isolates the water tank from external rainwater, salt spray and silt. Its excellent elasticity and toughness can reduce the possibility of splashed gravel damaging the surface of the water tank, further improving the practicality of the device.
