Description

Technical Field

[0001] This utility model relates to the field of asphalt paving, specifically to a road asphalt paving edge trimming device. Background Technology

[0002] During the cooling process of the paved asphalt pavement, the edges may lift due to thermal expansion and contraction. It is necessary to use an edge pressing device to trim and press the edges of the asphalt pavement before it is completely cooled. Edge pressing includes two types: bevel pressing and flat pressing. Bevel pressing occurs when the edge of the pavement is required to be at an angle of about 45 degrees to the flat pressing edge (using a bevel pressing roller), and when it is impossible to approach the curb, but it is necessary to compact the surface layer near the curb.

[0003] However, when using a ramp roller to trim and press the edges of an asphalt pavement, it must be done while the asphalt pavement is not completely cooled and hardened. This allows the asphalt pavement to be pressed into a ramp shape. However, the asphalt pavement still has a certain amount of heat at this time. In high outdoor temperatures, when the roller comes into contact with the asphalt pavement, the not-fully-softened asphalt can easily adhere to the roller surface, causing the roller surface temperature to rise. This requires frequent manual cleaning after stopping the machine, which is time-consuming and labor-intensive. Furthermore, if the roller surface temperature is too high, the asphalt may harden due to delayed cleaning, making cleaning difficult.

[0004] Therefore, it is necessary to invent a road asphalt paving edge trimming device. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a road asphalt paving edge trimming device, comprising a connecting arm, a fixed frame, and an inclined roller. The fixed frame is fixedly installed on one side of the connecting arm, and the inclined roller is rotatably connected to the middle of the side of the fixed frame away from the connecting arm. A cleaning scraper is installed on one side of the outer end of the fixed frame. A water storage tank is provided above the connecting arm, and a water spraying assembly is connected below the water storage tank.

[0007] Based on the above features: the water spraying assembly can draw cooling water from the water tank to cool the inclined roller, and the cleaning scraper can scrape and clean the surface of the inclined roller, minimizing the adhesion of asphalt to the surface of the inclined roller.

[0008] Preferably, the fixing frame has symmetrical connecting holes on both sides of its surface, and a through hole is provided on the surface of the fixing frame near the connecting arm.

[0009] Based on the above features: the cleaning scraper is connected to the mounting frame through the connecting hole, and the end of the water spraying component away from the water storage tank can pass through the through hole to the middle of the mounting frame.

[0010] Preferably, the cleaning scraper has symmetrical lugs welded to both sides at one end, and a movable hole is provided in the middle of the lug, with a fastening screw movably connected inside the movable hole.

[0011] Based on the above features: when installing the cleaning scraper, align the movable hole in the middle of the lugs on both sides with the connecting hole, and then use fastening screws to fix it through, so as to facilitate the cleaning scraper's movement and disassembly.

[0012] Preferably, the lower end of the cleaning scraper is configured as an inclined surface, and the lower part of the cleaning scraper matches the surface of the inclined pressure roller.

[0013] Based on the above features, it is convenient for the lower end of the cleaning scraper to adhere to the surface of the inclined pressure roller for scraping.

[0014] Preferably, the water spraying assembly includes a micro water pump and a water pumping pipe connected to the output end of the micro water pump, and a water delivery hose is connected to the output end of the micro water pump.

[0015] Based on the above characteristics: when the micro water pump is started, it can draw cooling water from the water storage tank through the pumping pipe and then transport it through the water delivery hose.

[0016] Preferably, a power cord is electrically connected to the rear of the micro water pump, and a contact switch is installed at the end of the power cord away from the micro water pump.

[0017] Based on the above features: when the drive connecting arm drives the fixed frame and the inclined pressure roller to descend and rise, the micro water pump can be automatically turned on or off by a contact switch without manual operation.

[0018] Preferably, a guide tube is installed at the end of the water delivery hose away from the micro water pump, and a two-way valve is installed at the other end of the guide tube. An atomizing nozzle is threadedly connected to the lower end of the two-way valve.

[0019] Based on the above characteristics: after the cooling water is introduced into the guide pipe through the water supply hose, it is diverted by the two-way valve, and finally the cooling water will be sprayed out through the atomizing nozzle.

[0020] The beneficial effects of this utility model are:

[0021] 1. The cleaning scraper and water spraying components can clean and cool the inclined roller. When the inclined roller is pressing and trimming the edge of the asphalt pavement, the micro water pump can be started to draw cooling water from the water tank. Then, the cooling water is delivered to the atomizing nozzle through the water delivery hose, guide pipe and double valve. Finally, the cooling water will be sprayed out through the atomizing nozzle to cool the inclined roller. The cleaning scraper on the outer side of the fixed frame can scrape and clean the surface of the inclined roller, so as to avoid the asphalt that is not fully softened adhering to the roller surface and eliminate the need for frequent machine shutdowns for cleaning.

[0022] 2. The miniature water pump can be automatically started and stopped by a contact switch. When the operator controls the hydraulic rod to retract, the hydraulic rod can drive the end of the connecting arm away from the inclined roller to move upward. At this time, the upward-moving end of the connecting arm will contact the contact switch, causing the miniature water pump to start and draw cooling water from the water storage tank. Meanwhile, the inclined roller at the other end of the connecting arm can move downward until it contacts the ground, pressing and trimming the edge of the asphalt pavement. When the operator controls the hydraulic rod to extend, the hydraulic rod can drive the end of the connecting arm away from the inclined roller to move downward. At this time, the downward-moving end of the connecting arm will gradually move away from the contact switch, and the miniature water pump will also shut down and stop pumping water. No manual operation is required to start it. Attached Figure Description

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] See attached document Figure 5 The existing product structure includes a road roller body, a roller on one side of the road roller body, a connecting frame on the top of the roller, a base on the outer surface of the connecting frame, a mounting plate on the bottom of the base, a hydraulic rod on the outside of the mounting plate, a first connecting shaft and a second connecting shaft on both ends of the hydraulic rod, the hydraulic rod is connected to the mounting plate through the first connecting shaft, and the other end of the hydraulic rod is movably connected to the connecting arm 1 through the second connecting shaft. A movable shaft is provided on the side of the connecting arm 1 adjacent to the support frame, so that the connecting arm 1 forms a lever structure. A fixed frame 2 is fixedly welded to the end of the connecting arm 1 away from the hydraulic rod, and a rotatable inclined roller 3 is installed in the middle of the fixed frame 2.

[0031] In use, when the operator controls the hydraulic rod to retract, the hydraulic rod can drive the end of the connecting arm 1 away from the inclined roller 3 to move upward, while the inclined roller 3 at the other end of the connecting arm 1 can move downward until the inclined roller 3 contacts the ground (edge ​​of the asphalt pavement). When the roller body moves on the asphalt pavement, the inclined roller 3 will be located at the edge of the asphalt pavement. At this time, due to the self-weight and friction of the inclined roller 3, it can rotate around its own axis to achieve the work of pressing the inclined edge. When the operator controls the hydraulic rod to extend, the hydraulic rod can drive the end of the connecting arm 1 away from the inclined roller 3 to move downward, while the inclined roller 3 at the other end of the connecting arm 1 can move upward until the inclined roller 3 is away from the ground, and then the inclined roller 3 can be stored.

[0032] See attached document Figure 1-4 A road asphalt paving edge trimming device includes a connecting arm 1, a fixing frame 2, and an inclined roller 3 (with an inclined angle of 45 degrees). The fixing frame 2 is fixedly installed on one side of the connecting arm 1, and the inclined roller 3 is rotatably connected to the middle of the side of the fixing frame 2 away from the connecting arm 1. A cleaning scraper 4 is installed on one side of the outer end of the fixing frame 2 to facilitate scraping and cleaning the surface of the inclined roller 3. A water storage tank 5 is provided above the connecting arm 1. The water storage tank 5 is fixed to one side of the outer end of the connecting frame by bolts, and a water inlet is provided above the water storage tank 5. Cooling water can be poured into the inner cavity of the water storage tank 5 through the water inlet. A water spraying component 6 is connected below the water storage tank 5 to facilitate the delivery of the cooling water inside the water storage tank 5 to the inside of the fixing frame 2 for spraying. This not only facilitates the cooling of the inclined roller 3 but also facilitates the cleaning scraper 4 to clean and scrape the material.

[0033] The fixing frame 2 has symmetrical connecting holes 21 on both sides to facilitate the positioning and fixing of the cleaning scraper 4. The cleaning scraper 4 has lugs 41 symmetrically welded on both sides at one end. The lugs 41 have a movable hole 42 in the middle. When the cleaning scraper 4 is installed, the movable hole 42 in the middle of the lugs 41 on both sides is aligned with the connecting hole 21, and then the fastening screw 43 is used to fix it through, which facilitates the cleaning scraper 4 to be moved and disassembled. At this time, the fixed cleaning scraper 4 will be located on one side of the outer end of the fixing frame 2 and above the inclined pressure roller 3. The lower end of the cleaning scraper 4 is set as an inclined surface. The lower part of the cleaning scraper 4 matches the surface of the inclined pressure roller 3, which makes it easy for the lower end of the cleaning scraper 4 to stick to the surface of the inclined pressure roller 3 for scraping.

[0034] The sprinkler assembly 6 includes a miniature water pump 61 (model DC40) and a water suction pipe 62 connected to the output end of the miniature water pump 61. The end of the water suction pipe 62 away from the miniature water pump 61 is connected to the bottom of the water storage tank 5. A water delivery hose 63 is connected to the output end of the miniature water pump 61. When the miniature water pump 61 is started, it can draw cooling water from inside the water storage tank 5 through the water suction pipe 62 and then deliver it through the water delivery hose 63. A guide pipe 6 is installed at the end of the water delivery hose 63 away from the miniature water pump 61. 31. A through hole 22 is provided on the surface of the fixed frame 2 near the connecting arm 1. The guide tube 631 moves through the through hole 22. A double-way valve 632 is installed at the other end of the guide tube 631 (the double-way valve 632 is fixed to the upper end of the inner cavity of the fixed frame 2 by screws). The lower end of the double-way valve 632 is threaded with an atomizing nozzle 633. When the cooling water is introduced into the guide tube 631 through the water supply hose 63, it is diverted by the double-way valve 632, and finally the cooling water will be sprayed out through the atomizing nozzle 633.

[0035] Based on the above structural effects, this application includes the following embodiments:

[0036] When installing the cleaning scraper 4, align the movable hole 42 in the middle of its two lugs 41 with the connecting hole 21, and then fix it with the fastening screw 43. At this time, the fixed cleaning scraper 4 will be located on one side of the outer end of the fixing frame 2 and above the inclined roller 3. When the operator controls the hydraulic rod to retract, the hydraulic rod can drive the end of the connecting arm 1 away from the inclined roller 3 to move upward, while the inclined roller 3 at the other end of the connecting arm 1 can move downward until the inclined roller 3 contacts the ground (edge ​​of the asphalt pavement). When the roller body moves on the asphalt pavement, the inclined roller 3 will move downward. The surface roller 3 will be located at the edge of the asphalt pavement. At this time, due to the weight of the surface roller 3 and the friction, the surface roller 3 can rotate around its own axis to achieve the work of pressing the inclined edge. During this process, the micro water pump 61 can be started and the cooling water inside the water storage tank 5 can be drawn through the water pumping pipe 62. Then the cooling water is delivered to the atomizing nozzle 63 through the water delivery hose 63, the guide pipe 631 and the double-way valve 632. Finally, the cooling water will be sprayed out through the atomizing nozzle 633, while the cleaning scraper 4 can scrape and clean the surface of the surface roller 3.

[0037] See attached document Figure 1-2 A power cord 611 is electrically connected to the rear of the miniature water pump 61. A contact switch 612 (model B3F-1000) is installed at the end of the power cord 611 away from the miniature water pump 61. The contact switch 612 is fixed to the surface of the mounting plate with screws. The contact switch 612 is electrically connected to the miniature water pump 61 through the power cord 611. (The contact switch 612 is the on / off switch of the miniature water pump 61. The specific circuit is not described in detail. In the existing technology, when the contact switch 612 cannot be automatically opened or closed due to the influence of the surrounding environment, it can be manually operated to open or close.)

[0038] Based on the above structural effects, this application includes the following embodiments:

[0039] According to the existing technology, when the operator controls the hydraulic rod to retract, the hydraulic rod can drive the end of the connecting arm 1 away from the inclined pressure roller 3 to move upward, while the other end of the connecting arm 1, the inclined pressure roller 3, can move downward until the inclined pressure roller 3 touches the ground. At this time, the upward-moving end of the connecting arm 1 will contact the contact switch 612, causing the micro water pump 61 to start and draw cooling water from the water storage tank 5. When the operator controls the hydraulic rod to extend, the hydraulic rod can drive the end of the connecting arm 1 away from the inclined pressure roller 3 to move downward, while the other end of the connecting arm 1, the inclined pressure roller 3, can move upward until the inclined pressure roller 3 is away from the ground. At this time, the downward-moving end of the connecting arm 1 will gradually move away from the contact switch 612, and the micro water pump 61 will also shut down and stop pumping water.
