Description

Technical Field

[0001] This utility model belongs to the technical field of highway maintenance equipment, and specifically relates to a rubber-tired roller anti-sticking device. Background Technology

[0002] Asphalt mixture compaction is the final step in asphalt pavement construction. During asphalt pavement maintenance, the problem of asphalt mixture adhering to the roller tires frequently occurs. To address this common issue and ensure better pavement compaction and construction quality, a designated person typically follows the roller, using a mop or roller brush dipped in clear oil to apply it to the tire surface. This prevents asphalt from adhering to the tires. If asphalt mixture sticks to the tires, it must be manually removed before continuing construction. However, due to the large size of rubber-tired rollers and their correspondingly large blind spots, maintenance personnel closely following the rollers to apply oil pose a significant safety risk.

[0003] To address the aforementioned problems, existing technologies include adding an oil spraying mechanism to the front and rear rubber tires of the road roller, replacing manual oil application. For example, Chinese utility model patent (CN119021063A) discloses an anti-sticking device for asphalt pavement compaction tire rollers. This patent features an integrated windproof cover on the outer side of the front and rear rubber tires of the road roller, covering all the tires, with an oil spray nozzle at the corresponding position on each tire. Simultaneously, a heating structure is installed inside the windproof cover to reduce the viscosity of the asphalt by blowing hot air into the cover, thus further reducing adhesion.

[0004] However, the aforementioned existing technologies have many problems in practical use.

[0005] 1. Although each rubber tire has an independent fuel injector, the fuel spray range of the fuel injector is distributed in a cone shape, resulting in dense fuel in the middle area of ​​the tire tread, while the fuel coverage in the edge area of ​​the tread is insufficient, and some edge areas even have no effective fuel film, resulting in large fluctuations in the anti-sticking effect.

[0006] 2. The bottom of the wind shield needs to have a large opening to accommodate the rotation of the rubber wheel. This causes the oil sprayed by the nozzle to splash into the gaps on both sides of the rubber wheel after colliding with it. Some of the oil is sprayed directly into the gaps between the rubber wheels and cannot be recycled, resulting in a large loss of oil.

[0007] 3. Since the wind shield is an integral structure covering multiple sets of rubber tires and is rigidly connected to the roller body by bolts, when asphalt adheres to a single set of rubber tires, the fixing bolts of the wind shield must be removed first and the entire shield must be removed before the sticky asphalt can be cleaned. The whole process takes a long time and requires interrupting the rolling operation, which is not conducive to the construction progress. Utility Model Content

[0008] The purpose of this utility model is to provide a rubber-tired anti-sticking device for rubber-tired rollers, aiming to solve the problems existing in the prior art mentioned above.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A rubber-tired roller anti-sticking device includes an oil storage tank, an oil pump, and a nozzle, which are installed on the roller and connected in sequence via an oil supply pipe. The nozzle is used to spray oil onto the surface of the rubber tire. A cover with a bottom opening is fitted over the outside of the nozzle. The cover is adapted to the width of the rubber tire surface of the roller. Brushes and oil outlet holes are provided on both sides of the bottom opening of the cover. The brushes are arranged along the width direction of the rubber tire surface. An oil collection chamber is provided inside the cover. An oil inlet hole is provided on the surface of the cover for connection with the oil pump via an oil supply pipe. The oil inlet hole and the oil outlet hole are respectively connected to the oil collection chamber. The oil outlet hole is used to supply oil to the brushes and to brush the oil onto the surface of the rubber tire through the brushes.

[0010] Furthermore, the cover is provided with a scraper, which is located on the outside of the brush bristles and spaced apart from the rubber tire surface. The scraper is used to scrape off the asphalt adhering to the rubber tire surface.

[0011] Furthermore, it also includes a support frame, which includes a U-shaped fixed frame and a mounting frame. The fixed frame includes a fixed rod and fixed sleeves vertically arranged at both ends of the fixed rod. The fixed sleeves are provided with a first fixed hole that runs vertically through the top and bottom. The mounting frame includes a support rod and connecting rods vertically arranged at both ends of the support rod. The connecting rods slide through the fixed sleeves. The sliding rods are provided with two sets of second fixed holes spaced apart along the axial direction. The first fixed holes and the second fixed holes are connected by bolts. The cover is arranged on the support rod.

[0012] Furthermore, the inner side of the cover is a semi-circular arc surface, and an oil collection groove is provided on the semi-circular arc surface, the oil collection groove extending along the circumference of the semi-circular arc surface.

[0013] Furthermore, it also includes a controller, with a first solenoid valve and a second solenoid valve respectively provided on the outside of the cover. The first solenoid valve is used to control the opening and closing of the oil supply pipe for supplying oil to the nozzle, and the second solenoid valve is used to control the opening and closing of the oil supply pipe for supplying oil to the oil collection chamber. The controller is electrically connected to the first solenoid valve, the second solenoid valve and the oil pump respectively.

[0014] Furthermore, the bristles are made of nylon 66 material.

[0015] Furthermore, the distance between the scraper and the tire tread is 0.5-1cm.

[0016] Compared with the shortcomings and deficiencies of the prior art, the present invention has the following beneficial effects.

[0017] 1. This utility model provides a rubber-tired roller anti-sticking device, employing a dual oil supply method combining atomized spraying from a nozzle and uniform brushing. The atomizing nozzle sprays oil onto the tire surface, while the brushes on both sides of the cover are moistened with oil through the oil collection chamber. As the tire rotates, the oil is evenly brushed along the width of the tire tread, forming a continuous and uniform oil film. The bottom opening of the cover is semi-closed, preventing oil sprayed from the nozzle and splashing from collisions with the tire tread. The oil collection groove on the inner wall of the cover collects the oil and guides it to the brushes on both sides, allowing the oil that would otherwise be lost to be reused for tire tread brushing, thereby reducing oil waste.

[0018] 2. In this utility model, when asphalt adheres to a single set of rubber wheels, there is no need to remove any overall cover. The adhered material can be scraped off simultaneously during the compaction operation by a scraper without interrupting construction, thus ensuring the continuity of the compaction operation and guaranteeing construction efficiency.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] Example 1

[0028] Refer to Figure 1 and Figure 7 This embodiment discloses a rubber-tired roller anti-sticking device, including a support frame 300 and a plurality of oil spraying components 200 disposed on the support frame 300. The number of oil spraying components 200 is the same as that of the rubber tire 110 and their positions correspond. The oil spraying components 200 are used to spray oil onto the rubber tire 110 to prevent asphalt from adhering to the rubber tire 110. The roller 100 is equipped with an oil storage tank 600 and an oil pump 400. The oil storage tank 600, the oil pump 400 and the oil spraying components 200 are connected in sequence through an oil supply pipe.

[0029] A protective frame 120 is installed on the outer side of the front and rear rubber tires 110 of the road roller 100. The protective frame 120 includes a guardrail located on the outer side of the rubber tires 110, and a mounting rod for connecting the road roller 100 and the guardrail. The mounting rod passes over the gap between adjacent rubber tires 110.

[0030] Reference Figure 2 The support frame 300 includes a U-shaped fixing frame 310 and a mounting frame 320. The fixing frame 310 includes a fixing rod 311, with fixing sleeves 312 vertically connected to both ends of the fixing rod 311. The fixing sleeves 312 can be rigidly connected to the fixing rod 311 by welding or bolting. A first through-hole is provided near the end of the fixing sleeve 312. The fixing rod 311 is fixed to the upper edge of the guardrail, and the end of the fixing sleeve 312 faces the road roller 100. The mounting frame 320 includes a support rod 321, which is parallel to the fixing rod 311. The two ends of the support rod 321 are vertically connected to... The connecting rod 322 slides through the fixed sleeve 312, and the relative position of the mounting bracket 320 with respect to the fixed bracket 310 is adjusted by sliding. The connecting rod 322 is provided with a second fixing hole 323 that runs vertically through it. Two sets of the second fixing holes 323 are arranged at intervals along the axial direction of the connecting rod 322. When the connecting rod 322 slides to different positions, the second fixing hole 323 is aligned with the first fixing hole and fixed by bolts, thereby realizing the position adjustment of the mounting bracket 320. A stop ring 324 is provided at the end of the connecting rod 322 away from the support rod 321. The stop ring 324 is used to prevent the connecting rod 322 from coming out of the fixed sleeve 312.

[0031] Reference Figure 3 - Figure 5 The oil spraying component 200 includes a cover 210 with an opening at the bottom. A nozzle 220 is inserted through the center of the top of the cover 210. The nozzle 220 is an atomizing nozzle and is connected to the oil pump 400 via an oil supply pipe. The cover 210 has the same width as the tread of the rubber wheel 110, that is, the lateral dimension of the cover 210 is consistent with the width of the rolling working surface of the rubber wheel 110. Brushes 230 are provided on both sides of the opening of the cover 210. The brushes 230 are evenly distributed along the width direction of the tread of the rubber wheel 110. Multiple sets of brushes 230 units are arranged laterally to form a continuous covering strip. An oil inlet is provided on the top surface of the cover 210. An oil collection chamber 232 is provided inside the cover 210. The oil inlet is connected to the oil collection chamber 232 and is connected to the oil pump 400 via an oil supply pipe. Multiple oil outlets 233 are evenly distributed on the end face of the cover 210 where the brushes 230 are located. The oil outlets 233 are connected to the oil collection chamber 232. The oil is discharged through the oil outlet 233 and wets the brush bristles 230. When the brush bristles 230 come into contact with the tire surface of the rubber wheel 110, as the rubber wheel 110 rotates, the brush bristles 230 evenly brush the oil onto the surface of the rubber wheel 110.

[0032] The bristles 230 are made of nylon, specifically nylon 66 (PA66). Nylon has moderate oil absorption, which allows the oil delivered through the oil outlet 233 to fully wet the bristles 230, ensuring the oil supply during brushing, without wasting oil due to excessive absorption.

[0033] The inner side of the cover 210 is semi-circular, and an oil collection groove 211 is provided on the semi-circular surface. The oil collection groove 211 extends along the circumference of the semi-circular surface to guide the oil to flow in the circumferential direction to the brush bristle 230 area on both sides. When the brush bristles 230 contact the tire tread of the rubber wheel 110, the cover 210 covers the outside of the rubber wheel 110. The bottom edge of the cover 210 is close to the tire tread. The nozzle 220 sprays oil onto the tire tread. The splashed oil can be effectively collected on the inner wall of the cover 210 and guided to the brush bristles 230 on both sides through the oil collection groove 211, thereby effectively improving the oil utilization rate.

[0034] The top of the cover 210 is provided with a connector 250, which is used to connect with the support rod 321. The connector 250 can be a stainless steel sleeve, which is fitted onto the support rod 321 and fixed by welding. Alternatively, it can be a semi-encircling structure with an open top, the opening width of which is set to 1 / 3 of the outer diameter of the support rod 321, ensuring that the sleeve can be easily fitted onto the support rod 321 through the opening while providing a stable enclosure for the support rod 321. Two symmetrical clamping lugs extend radially outward from the opening of the sleeve, with the thickness of the lugs being the same as the wall thickness of the sleeve. Corresponding coaxial bolt holes are opened on the lugs, and the sleeve is fixed to the support rod 321 by bolts.

[0035] One side of the brush bristles 230 is fixed by a fixing plate 234. The bottom of the fixing plate 234 is used to fix the brush bristles 230, and the top two ends are provided with connecting plates 235. Correspondingly, the two sides of the cover 210 are provided with corresponding slots. The connecting plates 235 are inserted into the slots and fixed by bolts. The fixing plate 234 is provided with a through hole 236 that communicates with the oil outlet hole 233. The top surface of the through hole 236 is provided with a sealing ring. When the fixing plate 234 is installed at the bottom of the cover 210, the through hole 236 communicates with the oil outlet hole 233. Under the action of the sealing ring, the oil flows into the through hole 236 through the oil outlet hole 233 and flows out to the brush bristles 230.

[0036] The bottom of the fixing plate 234 has multiple sets of bristle fixing grooves along its length. The roots of the bristle bundles 230 are bonded to and embedded in the fixing grooves with epoxy resin, and the tops of the bristle bundles 230 extend out of the fixing grooves. Connecting plates 235 extend vertically upwards from both ends of the top of the fixing plate 234, with bolt holes at the ends of the connecting plates 235 away from the fixing plate 234. Correspondingly, the bottom of both sides of the cover 210 has slots adapted to the connecting plates 235, and coaxial threaded holes are formed on the sidewalls of the slots corresponding to the bolt holes of the connecting plates 235. During installation, the connecting plates 235 at both ends of the fixing plate 234 are horizontally inserted into the slots along the opening direction until the connecting plates 235 are flush with the bottom of the slots. Then, bolts are passed through the bolt holes of the connecting plates 235 and screwed into the threaded holes of the slots in the cover 210, achieving detachable fixing of the fixing plate 234 and the cover 210, facilitating subsequent replacement and maintenance of the bristles 230 after wear.

[0037] Multiple sets of circular through holes 236 are formed along the length of the fixed plate 234. The diameter of the holes is the same as that of the oil outlet holes 233, and the positions of the through holes 236 correspond one-to-one with the oil outlet holes 233, forming an oil flow channel. At the same time, a rubber sealing ring is provided around each set of through holes 236 on the top surface of the fixed plate 234. The sealing ring is fixed to the fixed plate 234 by adhesive bonding. When the fixed plate 234 is fixed to the cover 210 by the connecting plate 235 and the slot bolts, the sealing ring is tightly squeezed between the fixed plate 234 and the cover 210, completely sealing the gap at the connection between the through holes 236 and the oil outlet holes 233, preventing oil leakage. At this time, the oil in the oil collection chamber 232 of the cover 210 can flow through the oil outlet holes 233 and the through holes 236 of the fixed plate 234 in sequence, accurately flowing to the root of the bristle bundle 230, ensuring that the bristles 230 are evenly wetted and guaranteeing the brushing effect.

[0038] Referring to Figure 6, a controller 500 is installed on the roller 100. A first solenoid valve 221 and a second solenoid valve 231 are respectively installed on the outer top of the cover 210. The first solenoid valve 221 is an electrically controlled valve installed on the oil supply pipe of the nozzle 220, used to switch the opening or closing state of the oil circuit of the nozzle 220. The second solenoid valve 231 is an electrically controlled valve installed on the oil supply pipe of the oil collection chamber 232. The controller 500 is electrically connected to the first solenoid valve 221, the second solenoid valve 231, and the oil pump 400. The controller 500 is used to control the start and stop of the oil pump 400, and to control the opening and closing of the first solenoid valve 221 and the second solenoid valve 231. Specifically, the controller 500 can be a Siemens S7-1200 series, which has abundant integrated I / O interfaces and can meet the connection requirements with the first solenoid valve 221, the second solenoid valve 231, and the oil pump 400.

[0039] The above settings can achieve the following: Turn on the power to the road roller 100 and set the oil supply pressure of the oil pump 400 to 0.3-0.5 MPa through the operating interface of the controller 500. Remove the bolts on the fixing sleeve 312, slide the connecting rod 322 along the axial direction of the fixing sleeve 312, and drive the support rod 321 and the cover 210 to move so that the bristles 230 at the bottom of the cover 210 just make slight contact with the tire tread of the rubber wheel 110. Tighten the bolts to fix the connecting rod 322.

[0040] The controller 500 sends a start command, and the oil pump 400 starts operating. Simultaneously, the first solenoid valve 221 and the second solenoid valve 231 open synchronously. Oil flows out of the oil tank and is divided into two paths via the oil delivery pipe: one path is delivered through the first solenoid valve 221 to the atomizing nozzle 220 on the top of the cover 210, and the other path is delivered through the second solenoid valve 231 to the oil inlet on the top surface of the cover 210 and enters the oil collection chamber 232. The oil in the oil collection chamber 232 seeps out evenly through the oil outlet 233 on the end face of the cover 210, gradually wetting the entire bristle bundle 230 until a uniform oil film forms on the surface of the bristles 230; at the same time, the atomizing nozzle 220 sprays atomized oil onto the tread of the rubber wheel 110.

[0041] The roller 100 begins to travel along the asphalt road surface, and the rubber wheel 110 rotates accordingly. As the brush bristles 230 maintain slight contact with the tire tread, during the rotation of the rubber wheel 110, the oil-soaked brush bristles 230 will slide synchronously with the direction of tire tread rotation, evenly brushing the oil onto all parts of the tire tread.

[0042] The atomizing nozzle 220 continuously sprays atomized oil onto the tire tread, working in conjunction with the brush bristles 230 to thoroughly coat the tire tread of the rubber wheel 110. Simultaneously, the splashing oil generated by the nozzle 220 is blocked by the inner wall of the cover 210 and then flows along the oil collection groove 211 on the inner wall to the brush bristles 230 on both sides, where it is reused, significantly reducing oil loss and improving oil utilization. During this process, the brush bristles 230 can be intermittently supplied with oil by opening the second solenoid valve 231 at intervals, keeping the brush bristles 230 in a moistened state.

[0043] Example 2

[0044] Example 2 is a further improvement on Example 1.

[0045] This embodiment discloses a rubber-tired roller anti-sticking device, which enables the oil spraying component 200 to scrape off asphalt blocks adhering to the surface of the rubber-tired roller 110.

[0046] Reference Figure 3 and Figure 4 A scraper 240 is installed on the outer side of the brush bristles 230 on the cover 210. The scraper 240 is connected to the cover 210 by bolts. When the brush bristles 230 contact the tire tread of the rubber wheel 110, the distance between the scraper 240 and the tire tread is 0.5-1cm. This can prevent the scraper 240 from scraping off the oil on the tire tread and ensure that the scraper 240 removes the asphalt blocks adhering to the tire tread.

[0047] The above settings can achieve the following: During the rotation of the rubber roller 110, the scraper 240 is spaced apart from the tire tread to ensure that the brush bristles 230 and the nozzle 220 work together to evenly spray the oil onto the tire tread of the rubber roller 110 to form an oil film layer. When asphalt particles that are not completely blocked by the oil film rotate with the rubber roller 110, the scraper 240 uses the relative motion generated by the rotation of the rubber roller 110 to scrape off the residual asphalt adhering to the tire tread. The scraped asphalt naturally falls off along the edge of the scraper 240 and goes outside the construction area. This process continues during the compaction operation, and the removal of adhering materials can be completed without interrupting the construction.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
