Description

Technical Field

[0001] This utility model relates to the field of engineering machinery and equipment technology, and in particular to a tire spraying protection device and a tire roller. Background Technology

[0002] A pneumatic tire roller, also known as a rubber-tired roller, is an indispensable compaction machine in highway, municipal, and national defense construction. The rollers of a pneumatic tire roller use inflatable tires; typically, the front wheel has 3-5 tires, and the rear wheel has 4-6 tires. The ground pressure can be adjusted by changing the tire inflation pressure, with a typical adjustment range of 0.11-1.05 MPa. Pneumatic tire rollers utilize the properties of inflatable tires to compact the material being compacted.

[0003] In practice, asphalt easily adheres to the tires of pneumatic tire rollers. Existing pneumatic tire rollers have liquid spraying devices that spray liquid onto the tires during operation to wet them and prevent adhesion. However, due to a lack of flow guidance, the sprayed liquid tends to splash, resulting in only a small amount remaining on the tires. This leads to poor wetting, asphalt adhesion, poor compaction, waste, and increased construction costs. Utility Model Content

[0004] This invention addresses the problem that current liquid spraying devices lack flow guidance, easily causing splashing of the sprayed liquid, resulting in poor wetting effect, waste, and increased construction costs. It proposes a tire spraying protection device and a tire roller.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a tire spraying protection device for installation on the frame of a road roller located above the tire. It includes a mounting base, which is fixedly connected to the frame. The mounting base is connected to a spraying mechanism, which is used to spray liquid at least. The mounting base is also connected to a flow guiding and protection mechanism, which is used to guide the liquid sprayed by the spraying mechanism to the surface of the tire at least.

[0007] Furthermore, the flow guidance and protection mechanism includes a flow guide cover, which includes a fixing part and a connected flow guide port and a receiving cavity. The fixing part is fixedly connected to the mounting base to cover the spraying mechanism inside the receiving cavity, and the flow guide port faces the tire.

[0008] Furthermore, the fairing body includes a brush skirt, which includes a brush portion and a connecting portion connected together. The connecting portion is fixedly connected to the periphery of the air intake, and the brush portion is in contact with the surface of the tire.

[0009] Furthermore, the spraying mechanism includes a drive control module and a nozzle. The drive control module is fixedly connected to the mounting base. The drive control module is equipped with a liquid infusion tube. The nozzle is connected to the drive control module and faces the tire. The drive control module is used at least to pressurize and deliver external liquid to the nozzle through the liquid infusion tube. The nozzle is used at least to atomize and spray the liquid.

[0010] Furthermore, a partition is provided inside the receiving cavity, which divides the receiving cavity into a first receiving space and a second receiving space. The drive control module is located in the first receiving space, and the nozzle is located in the second receiving space.

[0011] Furthermore, an observation window is provided at one end of the flow guide body relative to the flow guide port, and the observation window is connected to the second accommodating space.

[0012] Furthermore, the cross-sectional length of the guide shroud gradually increases along the spray direction of the nozzle.

[0013] Furthermore, the spraying mechanism includes a drive control module, and the flow guiding and protection mechanism includes an infusion brush. The drive control module is fixedly connected to the mounting base. The drive control module is provided with an infusion tube body. The infusion brush is connected to the drive control module. A flow chamber is provided at the root of the infusion brush. The infusion tube body communicates with the flow chamber. The infusion brush contacts the surface of the tire.

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

[0017] (1) This utility model, by setting up a flow guiding and protective mechanism, directs the liquid sprayed by the spraying mechanism to the surface of the tire, effectively reducing liquid splashing and increasing the amount of liquid retained on the tire, thereby improving the tire wetting effect. This reduces adhesion between the tire and asphalt during the operation of the tire roller, thus ensuring the compaction and flatness. At the same time, it effectively avoids waste of spraying liquid, reduces construction costs, and effectively reduces environmental pollution caused by liquid splashing.

[0018] (2) This utility model has a brush skirt fixed at the periphery of the guide port.

[0025] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0026] Example 1

[0027] Please see Figures 1-3A tire spraying protection device and a tire roller are disclosed, which are installed on a frame 410 of the roller above a tire 420. The device includes a mounting base 100, which is fixedly connected to the frame 410. A spraying mechanism 200 is connected to the mounting base 100. The spraying mechanism 200 is used to spray liquid at least. A flow guiding and protection mechanism 300 is connected to the mounting base 100. The flow guiding and protection mechanism 300 is used to guide the liquid sprayed by the spraying mechanism 200 to the surface of the tire 420 at least.

[0028] In this embodiment, as Figure 1 As shown, the device is installed on the frame 410 above the tire 420 of the tire roller. The device is located on the front side of the tire roller in the direction of travel. First, the mounting base 100 is fixed on the frame 410, and then the spraying mechanism 200 is fixed on the mounting base 100. During the travel of the tire roller, the spraying mechanism 200 can spray the spraying liquid onto the tire 420. In addition, a flow guiding and protection mechanism 300 is also fixed on the mounting base 100. The flow guiding and protection mechanism 300 can guide the liquid sprayed by the spraying mechanism 200 to the surface of the tire 420, thereby effectively reducing the amount of spraying liquid remaining on the tire 420 due to splashing.

[0029] In the above structure, the flow guiding and protective mechanism 300 directs the liquid sprayed by the spraying mechanism 200 to the surface of the tire 420, effectively reducing liquid splashing and increasing the amount of liquid retained on the tire 420. This improves the wetting effect of the tire 420, thereby reducing adhesion between the tire and asphalt during the operation of the pneumatic tire roller and ensuring compaction smoothness. Simultaneously, it effectively avoids waste of spraying liquid, reduces construction costs, and effectively reduces environmental pollution caused by liquid splashing.

[0030] The liquid sprayed by the spraying mechanism 200 can be oil, water, or an oil-water mixture, and the spraying liquid is existing technology.

[0031] In the specific structure of the flow guiding and protection mechanism 300, the flow guiding and protection mechanism 300 includes a flow guiding cover 310, which includes a fixing part 311 and a communicating flow guiding port and a receiving cavity. The fixing part 311 is fixedly connected to the mounting base 100 to cover the spraying mechanism 200 in the receiving cavity, and the flow guiding port faces the tire 420. The flow guiding cover 310 includes a brush skirt, which includes a brush part 320 and a connecting part 330 connected to each other. The connecting part 330 is fixedly connected to the periphery of the flow guiding port, and the brush part 320 is in contact with the surface of the tire 420.

[0032] In this embodiment, as Figure 2As shown, the flow guide shroud 310 can be a hollow shroud structure with an opening on one side. The hollow part inside forms a receiving cavity, and the opening forms a flow guide. The upper part of the flow guide shroud 310 is provided with a fixing part 311. During installation, the spraying mechanism 200 is first fixed on the mounting base 100, and then the fixing part 311 of the flow guide shroud 310 is fixedly connected to the mounting base 100, so that the spraying mechanism 200 is covered inside its receiving cavity. The flow guide of the flow guide shroud 310 faces the tire 420. By installing the spraying mechanism 200 in the receiving cavity, when the spraying mechanism 200 sprays liquid onto the tire 420 and splashes, the splashed liquid splashes back onto the inner wall of the receiving cavity, effectively preventing splashing to the outside. The liquid splashed onto the inner wall of the receiving cavity can accumulate again and flow back to the surface of the tire 420 through the flow guide, improving the wetting effect of the tire 420.

[0033] In addition, a brush skirt is fixed around the periphery of the flow inlet, and the connecting part 330 of the brush skirt is fixed at the edge of the flow inlet. The tail end of the brush part 320 contacts the surface of the tire 420, and the brush part 320 and the tire 420 can slide relative to each other. When the liquid splashed onto the inner wall of the receiving cavity flows back to the flow inlet, the liquid wets the brush part 320 and is brushed onto the surface of the tire 420 through the brush part 320, which is conducive to the formation of an oil film on the tire 420 and further improves the wetting effect of the tire 420. In addition, the brush part 320 can evenly coat the liquid on the tire 420, improving the uniformity of the oil film formation. At the same time, during the operation of the tire roller, the brush part 320 contacts the surface of the tire 420, which facilitates the cleaning of mud and sand on the surface of the tire 420, improves the cleaning effect of the tire 420, and further wets the tire 420.

[0034] In the specific structure of the spraying mechanism 200, such as Figure 1 , 2 As shown, the spraying mechanism 200 includes a drive control module 210 and a nozzle 220. The drive control module 210 is fixedly connected to the mounting base 100. The drive control module 210 is provided with an infusion tube 211. The nozzle 220 is connected to the drive control module 210 and faces the tire 420. The drive control module 210 is at least used to pressurize and deliver external liquid to the nozzle 220 through the infusion tube 211. The nozzle 220 is at least used to atomize and spray the liquid.

[0035] In this embodiment, the infusion tube 211 of the drive control module 210 can be connected to an external liquid storage mechanism to facilitate the delivery of spray liquid. The drive control module 210 can use a built-in pump or high-pressure gas as a power source to quantitatively deliver liquid to the nozzle 220 through the infusion tube 211 and control the nozzle 220 to atomize and spray the liquid. The nozzle 220 sprays towards the tire 420. This structure is simple, easy to control and spray, and improves spraying efficiency and spraying effect.

[0036] Furthermore, a partition is provided inside the receiving cavity, dividing it into a first receiving space and a second receiving space. The drive control module 210 is housed in the first receiving space, and the nozzle 220 is housed in the second receiving space. During installation, the drive control module 210 is installed in the first receiving space, and the nozzle 220 is installed in the second receiving space, thereby separating the drive control module 210 and the nozzle 220. This effectively prevents liquid sprayed by the nozzle 220 from splashing onto the drive control module 210, causing it to become damp. By setting up the partition to achieve dry and wet separation, the service life of the spraying mechanism 200 is effectively improved.

[0037] In particular, such as Figure 2 As shown, the guide shroud 310 has an observation window 314 at one end opposite the guide port, and the observation window 314 is connected to the second accommodating space. The cross-sectional length of the guide shroud 310 gradually increases along the spraying direction of the nozzle 220.

[0038] In this embodiment, the flow guide shroud 310 can be a trapezoidal shroud structure, wherein the shorter end is positioned away from the tire 420, and the longer end is positioned close to the tire 420. Since the nozzle 220 sprays liquid toward the tire 420, the closer it is to the tire 420, the larger its spray area. Therefore, positioning the longer end close to the tire 420 can improve the blocking of splashes. In addition, an observation window 314 is provided on the flow guide shroud 310 at one end opposite the flow guide port. This observation window 314 is connected to the second accommodating space, thereby allowing real-time monitoring of the spraying status of the nozzle 220 and facilitating timely maintenance.

[0039] In addition, such as Figure 3 As shown, the mounting base 100 has at least two mounting portions 110 along the width direction of the tires 420. Each mounting portion 110 connects the spraying mechanism 200 and the flow guiding and protection mechanism 300. Since a tire group 420 on one side of the pneumatic tire roller may be formed by combining two or more small tires 420, two or more mounting portions 110 are provided on the mounting base 100. Each mounting portion 110 is used to fix the spraying mechanism 200 and the flow guiding and protection mechanism 300, thereby meeting the needs of pneumatic tire rollers with different numbers of tires 420 and improving the applicability of the device.

[0040] It should be noted that all of the above-mentioned fixed connection methods can be bolted. In the connection between the mounting base 100 and the frame 410, the mounting hole of the mounting base 100 can be an oblong hole, which allows for a small adjustment of the installation direction. In addition, the mounting holes of oblong holes can be provided in the fixing of the spraying mechanism 200, the flow guiding and protection mechanism 300 and the mounting base 100 for easy adjustment.

[0042] A tire spraying protection device is provided in Embodiment 2. The structure is generally the same as that in Embodiment 1, except for the following: the spraying mechanism 200 includes a drive control module 210, and the flow guiding protection mechanism 300 includes an infusion brush. The drive control module 210 is fixedly connected to the mounting base 100. The drive control module 210 is provided with an infusion tube 211. The infusion brush is connected to the drive control module 210. A flow chamber is provided at the root of the infusion brush. The infusion tube 211 communicates with the flow chamber. The infusion brush contacts the surface of the tire 420. The drive control module 210 is at least used to transport external liquid to the flow chamber through the infusion tube 211, and the infusion brush is at least used to coat the tire 420 with liquid.

[0043] In this embodiment, the spraying mechanism 200 includes a drive control module 210, and the flow guiding and protection mechanism 300 includes an infusion brush. The infusion tube 211 of the drive control module 210 can be connected to an external liquid storage mechanism to facilitate the delivery of spraying liquid. The drive control module 210 can use a built-in pump or high-pressure gas as a power source to quantitatively deliver liquid through the infusion tube 211 to the flow chamber of the infusion brush, so that the liquid can continuously wet the infusion brush. The infusion brush is always in contact with the surface of the tire 420, effectively playing a guiding role, preventing liquid splashing, thereby improving the wetting effect on the tire 420, and also effectively cleaning the mud and sand on the tire 420.
