Description

Technical Field

[0001] This utility model relates to the field of road repair technology, and in particular to a pothole filling device for road construction. Background Technology

[0002] The current method of filling potholes in road construction is usually manual. The steps of manual pothole filling are as follows: First, the construction workers use various breaking tools to modify the edges of the pothole and shape it into a roughly regular shape. Then, the debris and waste inside the pothole are cleaned up. The repair material is poured into the pothole and leveled and compacted using tools such as a tamping machine. In order to ensure the quality of the repair, the construction workers need to repeat the two steps of pouring material and compacting, repeating it every 3-5 centimeters.

[0003] For example, Chinese invention patent with announcement number "CN116537026A" discloses a "pothole filling device for highway construction", which includes a trimming component, a guide hopper, a leveling component and a roller pressing component. The trimming component can be adjusted up and down and uses a planer wheel to trim the edge of the pothole into a regular rectangle. The guide hopper, the leveling component and the roller pressing component work together to compact the repair material into the pothole to be repaired.

[0004] The pothole filling device used in highway construction has components that can be optimized. However, due to the lack of a "cleaning component" between the "repairing component" and the "material guide hopper", after the construction workers use the device to repair the pothole, they need to remove the device and then manually clean up the debris and waste. This makes it impossible to achieve the integrated "pothole digging-compacting" steps, and the degree of manual involvement is relatively high. Utility Model Content

This device incorporates a cleaning component, eliminating the need for construction workers to remove the device and clean debris and waste after pothole repair. The cleaning component automatically cleans the debris and waste directly from the pothole, integrating the "trimming-compacting" steps, reducing manual intervention, improving work efficiency, and saving manpower.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a pothole filling device for road construction, including a device frame, a trimming component, a cleaning component, a guide hopper, a leveling component, and a roller pressing component; the trimming component, cleaning component, leveling component, and roller pressing component are all fixed inside the device frame and distributed along the FR direction; the height of the trimming component and the cleaning component can be adjusted up and down, and because they are fixed on the same horizontal plane, the height of the two is adjusted synchronously; the leveling component and the roller pressing component can be adjusted up and down; the guide hopper is located between the cleaning component and the leveling component and penetrates through the upper surface of the device frame.

Both the fourth and fifth driven gears are spur bevel gears, and they mesh perpendicularly. A cleaning brush is fixedly connected to one end of the gear shaft of the fifth driven gear. A debris collection box is placed on the upper surface of the third ear plate, and an inclined plate is connected to the side near the cleaning brush.

[0010] The aforementioned road construction pothole filling device has a guide hopper made of stainless steel, with a rectangular inlet and a circular outlet.

[0034] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0035] In the specific embodiments of this utility model, the directional terms such as "front" and "rear" are all used to describe... Figure 2 The directions indicated in the text are the references, where "F" corresponds to "forward" and "R" corresponds to "backward".

[0036] like Figure 1-7As shown, a pothole filling device for road construction includes a device frame 1, a trimming component 2, a cleaning component 3, a guide hopper 4, a leveling component 5, and a roller pressing component 6. The trimming component 2, cleaning component 3, leveling component 5, and roller pressing component 6 are all fixed inside the device frame 1 and distributed along the FR direction. The heights of the trimming component 2 and cleaning component 3 are adjustable, and since they are fixed on the same horizontal plane, their heights are adjusted synchronously. The leveling component 5 and roller pressing component 6 are also adjustable. The guide hopper 4 is located between the cleaning component 3 and the leveling component 5 and penetrates the upper surface of the device frame 1.

[0037] The device frame 1 includes a vehicle body 101 and wheels 102. The vehicle body 101 is hollow inside, and a control console 103 is fixed to one side of the vehicle body 101. The control console 103 can adjust the various motors and electro-hydraulic rods in the entire device. The vehicle body 101 is supported by an axle formed by the wheels 102. A first electro-hydraulic rod 104 is fixed to the upper surface inside the vehicle body 101. The other end of the first electro-hydraulic rod 104 is fixed to a first horizontal plate 105. A trimming component 2 and a cleaning component 3 are respectively fixed to the two ends of the lower surface of the first horizontal plate 105. When the control console 103 controls the first electro-hydraulic rod 104 to work, the first electro-hydraulic rod 104 synchronously adjusts the trimming component 2 and the cleaning component 3 to move in a direction perpendicular to the horizontal plane through the first horizontal plate 105.

[0038] like Figure 3 As shown, the trimming assembly 2 includes a second horizontal plate 201. The upper surface of the second horizontal plate 201 is fixedly connected to one end of the first horizontal plate 105. Second electro-hydraulic rods 202 are fixed to the lower surfaces of both ends of the second horizontal plate 201, and the second electro-hydraulic rods 202 are placed perpendicular to the horizontal plane. The other end of the second electro-hydraulic rods 202 is fixed to a first ear plate 203. A planer wheel 204 is installed inside the first ear plate 203. A first motor 205 is fixedly installed on the upper surface of the first ear plate 203. The output end of the first motor 205 is connected to a first drive gear. 206. The first driving gear 206 meshes with the first driven gear 207, and the first driven gear 207 meshes with the second driven gear 208. The second driven gear 208 is fixed on the rotating shaft of the planer wheel 204. When the first motor 205 works, it drives the first driving gear 206 to rotate, which in turn drives the first driven gear 207 to rotate. The first driven gear 207 then drives the second driven gear 208 to rotate, thereby driving the planer wheel 204 to rotate. The rotating motion of the planer wheel 204 shapes the pit to be repaired into a regular rectangle.

[0039] like Figure 4As shown, the cleaning component 3 includes a third horizontal plate 301. The upper surface of the third horizontal plate 301 is fixedly connected to the other end of the first horizontal plate 105. Third electro-hydraulic rods 302 are fixed to the lower surfaces of both ends of the third horizontal plate 301, and the third electro-hydraulic rods 302 are placed perpendicular to the horizontal plane. The other end of the third electro-hydraulic rod 302 is fixed to the upper surface of a connecting rod 303. The connecting rod 303 is placed horizontally, and a second ear plate 304 and a third ear plate 305 are fixed to its two ends respectively. A support rod is fixedly connected to the connecting rod 303. At one end of support rod 306, a second motor 307 is fixed to the other end. The output shaft of the second motor 307 is connected to a second driving gear 308, which meshes with a third driven gear 309. The third driven gear 309 extends axially to both sides, and a fourth driven gear 310 is fixedly connected to both ends of the gear shaft. The fourth driven gear 310 meshes with a fifth driven gear 311. Both the fourth driven gear 310 and the fifth driven gear 311 are spur bevel gears. The gears mesh vertically, and a cleaning brush 312 is fixedly connected to one end of the gear shaft of the fifth driven gear 311; a debris collection box 313 is placed on the upper surface of the third ear plate 305. The debris collection box 313 is detachable and can be removed and cleaned by pulling horizontally, and an inclined plate 314 is connected to the side near the cleaning brush 312; when the second motor 307 is working, its output shaft drives the second driving gear 308 to rotate, and the second driving gear 308 drives the third driven gear 309 to rotate. The teeth of the third driven gear 309... The axle drives the fourth driven gear 310 to rotate, and the fourth driven gear 310 drives the fifth driven gear 311 to rotate, thereby driving the two cleaning brushes 312 to rotate. The gear set in the cleaning assembly 3 is driven by the second motor 307. When the output shaft of the second motor 307 rotates clockwise, it ultimately drives the two cleaning brushes 312 to rotate in directions A and B respectively. The debris and waste are swept into the debris collection box 313 after passing through the inclined plate 314 by the rotating movement of the cleaning brushes 312, thus achieving the cleaning of debris and waste.

[0040] like Figure 5 As shown, the guide hopper 4 is made of stainless steel, with a rectangular inlet and a circular outlet. The construction workers guide a fixed amount of repair material into the inlet and then discharge it from the outlet, filling the regular pits with the repair material.

[0041] like Figure 6As shown, the leveling component 5 includes a fourth horizontal plate 501. Two fourth electric hydraulic rods 502 are vertically fixed to the upper surfaces of both ends of the fourth horizontal plate 501. The upper ends of the fourth electric hydraulic rods 502 are fixedly connected to the vehicle body 101 to adjust the height of the leveling component 5 in the vertical and horizontal directions. The lower surface of the fourth horizontal plate 501 extends and is fixedly connected to a third motor 504 through a motor base 503. The output shaft of the third motor 504 is perpendicular to the horizontal plane. A rotating scraper 505 is located directly below the third motor 504. The two are directly connected through the output shaft of the third motor 504. When the third motor 504 is working, its output shaft rotates clockwise, which simultaneously drives the rotating scraper 505 to rotate clockwise, thereby leveling the introduced repair material.

[0042] like Figure 7 As shown, the roller pressing assembly 6 includes a fifth horizontal plate 601. The upper surface of the fifth horizontal plate 601 is fixed to the vehicle body 101, and a pressure roller 602 is located directly below it horizontally. Two fifth electric hydraulic rods 603 are fixedly connected to both ends of the lower surface of the fifth horizontal plate 601. The lower ends of the fifth electric hydraulic rods 603 are fixedly connected to the roller shaft of the pressure roller 602, so as to realize the adjustment of the height of the pressure roller 602 in the vertical and horizontal directions.

[0043] The first driving gear 206, the first driven gear 207, the second driven gear 208, the second driving gear 308, the third driven gear 309, the fourth driven gear 310, and the fifth driven gear 311 are all protected by gear covers to prevent the trimming assembly 2 and the cleaning assembly 3 from being disturbed by the debris and waste generated during operation.

[0044] The rotary scraper 505 is zig-shaped. When the two scraper blades of the rotary scraper 505 rotate, they can evenly spread the repair material into the regular pit.

[0045] The planer wheel 204, two cleaning brushes 312, rotating scraper 505, and pressure roller 602 are all the same width, which can achieve the standardization of the filling of pits from breaking them into regular pits to compaction by pressure roller 602.

[0046] When this utility model is in operation, the construction personnel move the device to the upper end of the pit to be filled, and control the first electric hydraulic rod 104 through the control console 103 to adjust the trimming component 2 and the cleaning component 3 to a suitable horizontal height. The first motor 205 and the second motor 307 work, and drive the planing wheel 204 and the cleaning brush 312 to work through the gear system respectively, breaking the pit to be filled into regular pits while sweeping the debris and waste into the debris collection box 313.

[0047] After the debris and waste are cleaned up, the construction workers guide the repair materials into the regular pits through the guide hopper. The control console 103 controls the fourth electric hydraulic rod 502 to adjust the leveling component 5 to a suitable horizontal height. The third motor 504 drives the rotating scraper 505 to rotate, leveling the repair materials in the regular pits. After the repair materials are leveled, the control console 103 controls the fifth electric hydraulic rod 603 to adjust the pressure roller 602 to a suitable horizontal height. The repair materials are compacted by moving the roller back and forth. If the pits are deep, the above steps need to be repeated every 3-5 centimeters.

[0048] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
