Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of road surface crack repair, in particular to a crack pouring device for asphalt pavement crack repair. BACKGROUND

[0002] Asphalt pavement is a road surface paved with asphalt material. The asphalt material improves the ability of the paving granules to resist the damage of driving and natural factors to the road surface, making the road surface flat, less dusty, water-resistant and durable. The noise of the car driving on the asphalt pavement is relatively weak. Nowadays, asphalt pavement is a kind of senior pavement most widely used in road construction. During a long period of use, cracks may occur on the road surface due to pressure, and a crack pouring device is needed to fill the cracks.

[0003] When the road is repaired by using the repair device body, the material is first placed in the stirring tank through the feeding port for stirring to ensure the fluidity of the asphalt concrete and facilitate the subsequent discharging work. Then, the valve is opened to make the material enter the feeding hopper. When the material is accumulated in the feeding hopper, the control valve is opened to make the pouring hose fill the asphalt pavement.

[0004] Most of the existing crack pouring devices are manually held by the repair pipe to pour the slurry into the cracks. It is not convenient to control the speed and the amount of the slurry of the crack pouring device. The widths of the cracks are different. The uniform amount of the slurry may not be enough in the wider cracks, and the device may pour too much slurry in the narrower cracks, resulting in uneven crack repair, unevenly repaired road surface, waste of slurry, and the height of the crack pouring pipe cannot be adjusted on the road surface with different heights, which may cause asphalt splashing during the repair of the asphalt pavement. In addition, the temperature of the slurry in the asphalt bucket decreases after a period of time during the crack pouring process, which may gradually solidify and affect the subsequent use.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of the present invention will now be described.

[0040] A crack filling device for repairing asphalt pavement cracks, such as Figures 1 to 10 As shown, the device includes a crack filling cart 100, an adjustment mechanism 200 on the inner wall of the crack filling cart 100, a heating mechanism 300 fixedly connected to the top of the crack filling cart 100, a stirring mechanism 400 rotatably connected to the inner wall of the heating mechanism 300, a drying mechanism 600 fixedly connected to the bottom of the crack filling cart 100, a booster pump 500 fixedly connected to the top of the crack filling cart 100, and a scraper 800 fixedly connected to the bottom of the crack filling cart 100.

[0041] In the repair of asphalt pavement cracks, the staff pushes the crack pouring vehicle 100, inserts the slurry outlet of the adjusting mechanism 200 into the crack, and pushes the crack pouring vehicle 100. The adjusting mechanism 200 adjusts the flow of slurry according to the width of the crack, and the adjusting mechanism 200 changes the height of the slurry outlet in the crack at different depths. In order to prevent the unused slurry on the crack pouring vehicle 100 from cooling and solidifying for a long time, the heating mechanism 300 can heat the unused slurry, and the stirring mechanism 400 makes the heating of the heating mechanism 300 more uniform, prevents the slurry in the heating mechanism 300 from appearing solidified block due to uneven heating in some places, and blocks the pipeline, affects the normal discharge of the slurry. In the process of moving the crack pouring vehicle 100, the scraper 800 will scrape the filled slurry to be flush with the ground, and the air drying mechanism 600 will dry the slurry in the crack to a certain extent under the driving of the heating mechanism 300, and the air drying mechanism 600 will clean some dust in the crack before the adjusting mechanism 200 discharges the slurry. The part not involved in the device is the same as the existing technology or can be realized by adopting the existing technology.

[0042] Please refer to Figures 2 to 6The adjusting mechanism 200 comprises a sliding groove 210 opened in the inner wall of the crack pouring vehicle 100, a moving assembly 220 is slidably connected in the groove of the sliding groove 210, a fixed pipe 230 is fixedly connected to the inner wall of the moving assembly 220, an adjusting assembly 240 is fixedly connected to the bottom end of the fixed pipe 230, a connecting hose 270 is fixedly connected to the top end of the fixed pipe 230, a discharge pipe 250 is fixedly connected to the bottom end of the adjusting assembly 240, a fixed plate 280 is fixedly connected to the outer wall of the discharge pipe 250, a first spring 260 is fixedly connected in the groove of the sliding groove 210, the first spring 260 is provided in four groups, one end of the connecting hose 270 is fixedly connected in communication with a booster pump 500, the sliding groove 210 and the fixed plate 280 are both provided in two groups, and two groups of the sliding groove 210 are symmetrically arranged on the two sides of the moving assembly 220 and the fixed plate 280. The adjusting assembly 240 comprises a first circular plate 241 fixedly connected to the bottom end of the fixed pipe 230, a second circular plate 242 is rotatably connected to the bottom end of the first circular plate 241, a rotating groove 243 is opened in the second circular plate 242, a moving shaft 244 is slidably connected in the groove of the rotating groove 243, an outer gear strip ring 249 is fixedly connected to the outer wall of the second circular plate 242, a third circular plate 245 is rotatably connected to the bottom end of the second circular plate 242, a guide groove 246 is opened in the third circular plate 245, a moving block 247 is slidably connected in the guide groove 246, an opening and closing plate 248 is fixedly connected to the top end of the moving block 247, and the opening and closing plate 248 is fixedly connected between the moving shaft 244, the rotating groove 243, the moving block 247 and the opening and closing plate 248 are all provided in six groups, and six groups of the rotating groove 243, the moving shaft 244, the moving block 247 and the opening and closing plate 248 are arranged in a circumferential array with the center of the first circular plate 241 as the axis.

[0043] The booster pump 500 is started, and the slurry in the heating mechanism 300 enters the connecting hose 270 through the booster pump 500. The adjusting assembly 240 adjusts the size of the gap through which the slurry flows under the driving of the moving assembly 220, thereby adjusting the flow rate of the slurry discharged from the discharge pipe 250 into the crack. The positioning plate 226 is inserted into the asphalt pavement crack, thereby driving the moving assembly 220 to move longitudinally in the chute 210, and further driving the first spring 260 to be compressed. Since the crack sealing vehicle 100 is in contact with the ground, the depth of the crack changes the degree of compression of the first spring 260. When the crack is deeper, the first spring 260 is compressed to a smaller degree, and the position of the moving assembly 220 is lower, thereby driving the position of the lowest end of the discharge pipe 250 to be lower. When the crack is shallower, the first spring 260 is compressed to a larger degree, and the position of the moving assembly 220 is higher, thereby driving the position of the lowest end of the discharge pipe 250 to be higher. Thus, the height of the position of the discharge pipe 250 discharging the slurry can be adjusted according to the height of the crack.

[0044] During the movement of the crack sealing vehicle 100, the width of the crack changes the distance between the two groups of positioning plates 226, so that the two groups of positioning plates 226 move relatively, thereby driving the rack plate 225 to move, and further driving the moving strip 223 to move along the limiting groove 222. At this time, the second spring 224 is compressed. When the width of the crack becomes wider, the degree of compression of the second spring 224 becomes smaller, and the restoring force of the second spring 224 drives the moving strip 223 to move, thereby driving the rack plate 225 to move, and further driving the positioning plate 226 to move and fit the crack. The positioning plate 226 always fits the crack, thereby driving the rack plate 225 to move according to the width of the crack.

[0045] The rack plate 225 moves to drive the outer gear rack ring 249 to rotate, thereby driving the rotating groove 243 to rotate, and further driving the moving shaft 244 to move, and the moving shaft 244 moves to drive the opening and closing plate 248 to move, and the opening and closing plate 248 moves the moving block 247 to move, but under the limitation of the guide groove 246, the moving block 247 moves along the track of the guide groove 246, thereby the tip of the opening and closing plate 248 simultaneously moves towards or away from the center of the second circular plate 242, and six groups of the opening and closing plate 248 move between each other, and the slurry can pass through the gap between the six groups of the opening and closing plate 248 after being adhered, when the crack width is narrow, the two positioning plates 226 move close to each other to drive the rack plate 225 to move, thereby driving the second circular plate 242 to rotate, at this time, the six groups of the opening and closing plate 248 move close to the center of the second circular plate 242, thereby the gap in the adjusting assembly 240 for the slurry to pass through becomes smaller, at this time, the amount of slurry passing through the discharge pipe 250 is less, and when the crack width is wide, the second circular plate 242 drives the six groups of the opening and closing plate 248 to move away from the center of the second circular plate 242, thereby the gap in the adjusting assembly 240 for the slurry to pass through becomes larger, at this time, the amount of slurry passing through the discharge pipe 250 is more.

In order to heat the slurry more uniformly, the slurry in some places of the asphalt bucket 310 is not hot and the slurry in some places is cold and clumps, the motor 700 is started to drive the second rotating shaft 447 to rotate, thereby driving the worm gear 450 to rotate, and further driving the worm gear 460 to rotate. The worm gear 460 drives the third gear 471 to rotate, thereby driving the fourth gear 472 to rotate. Since the clamping block 473 is clamped in the clamping groove 474, the fourth gear 472 drives the clamping groove 474 to rotate when rotating, thereby driving the main shaft 410 to rotate under the driving of the fourth gear 472, and further driving the stirring plate 480 to rotate. The main shaft 410 drives the cross shaft 320 to rotate when rotating, thereby driving the large gear 330 to rotate, and further driving the first gear 340 to rotate around the fixed shaft 380 as the axis. The first gear 340 drives the inner gear strip ring 370 to rotate when rotating, thereby driving the rotating barrel 350 to rotate, and further driving the heating pipe 360 to rotate, so that the heating pipe 360 heats the asphalt bucket 310 more uniformly.

[0048] When the second rotating shaft 447 rotates, the second rotating block 446 rotates around the second rotating shaft 447 as the axis, thereby driving the second positioning shaft 445 to rotate, and further driving the connecting rod 444 to rotate, while driving the first positioning shaft 443 to rotate, thereby driving the first rotating block 442 to rotate around the first rotating shaft 441 as the axis, and further driving the first rotating shaft 441 to rotate, while driving the second gear 430 to rotate, thereby driving the cylindrical gear rack 420 meshed with the second gear 430 to move longitudinally, and further driving the main shaft 410 to move longitudinally while being driven to rotate by the rotating assembly 470.
