Description

Technical Field

[0001] This utility model belongs to the field of road surface maintenance technology, and specifically relates to a road surface maintenance device. Background Technology

[0002] With the rapid advancement of global urbanization, urban road networks are constantly expanding, and traffic flow is increasing dramatically. This not only leads to greater load pressure on road surfaces, accelerating their aging and damage, but also places higher demands on road surface durability and maintenance efficiency. Cracks are an early manifestation of various road defects, making crack treatment particularly important. Currently, common cracks in concrete pavements are generally repaired by manually pouring concrete pavement repair material into the cracks.

[0003] For example, Chinese patent CN 218492252 U discloses a road surface maintenance crack repair device. The device includes a base with a rectangular slot on its surface. A discharge pipe is fixedly connected to the inner wall of the slot via two symmetrically arranged connecting blocks. One end of the discharge pipe is fixedly connected to a mixing tank, and the other end is fixedly connected to a discharge pipe. A motor is mounted on the upper surface of the mixing tank, and a rotating rod is fixedly connected to the output shaft of the motor. This road surface maintenance crack repair device can pour concrete repair material into the mixing tank for mixing, and then, with the rotation of the rotating plate, discharge the mixed concrete repair material wave by wave to the cracks in the road surface for repair. By using machinery to replace manual labor, it reduces the burden on workers and avoids the need to pour concrete repair material onto the road surface for on-site mixing and subsequent road surface cleaning, thus improving repair efficiency.

[0004] Problems with existing technology:

[0005] In the above-mentioned process, after crack repair, during the process of moving the equipment to the next repair point, the motor drives the rotating rod and mixing rod to continuously rotate, stirring the concrete repair material in the mixing tank to prevent the concrete repair material in the mixing tank from solidifying. This practice may not only lead to an unnecessary increase in motor energy consumption, but may also increase the overall operating cost and maintenance requirements of the equipment due to long-term operation. Utility Model Content

[0006] The purpose of this utility model is to provide a road surface maintenance device that can mix the concrete repair material in the mixing tank while the device is moving, thus preventing the concrete repair material in the mixing tank from solidifying during movement and reducing the energy consumption of the device, making it more energy-efficient and environmentally friendly.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A road surface maintenance device includes a base plate, on the top of which is a mixing tank for loading concrete repair material. The mixing tank is integrally formed from top to bottom by a holding bucket, a conical hopper, and a discharge pipe. The discharge port at the bottom of the mixing tank extends below the base plate. A bearing is rotatably mounted at the center of the top of the mixing tank. A mixing shaft extending into the mixing tank is inserted into the bearing. A limiting groove is formed on the inner surface of the bearing. A limiting protrusion that slides through the limiting groove is fixed on the outer wall of the mixing shaft. A conical sealing cover is rotatably mounted at the bottom of the bearing. A sealing groove that mates with the conical sealing cover is formed at the discharge port of the mixing tank. A sealing ring is provided on the inner side of the sealing groove to increase the sealing performance of the connection between the conical sealing cover and the sealing groove.

[0009] A hydraulic cylinder for driving the stirring shaft to move up and down is provided on the top of the mixing tank and on one side of the stirring shaft. The output shaft of the hydraulic cylinder is fixed with a fixed plate that is rotatably connected to the stirring shaft. A first gear is fixed on the outer wall of the stirring shaft and above the fixed plate. A motor is provided on the top of the mixing tank. A second gear that cooperates with the first gear is fixed on the output shaft of the motor.

[0010] A third rotating shaft is rotatably mounted on the top of the mixing tank, and a third gear that meshes with the first gear is provided on the outer wall of the mixing tank above the second gear;

[0011] The bottom of the base plate is provided with mounting shafts on both sides, and rollers are provided at both ends of the mounting shafts. The third rotating shaft is provided with a linkage component for rotating the rollers to drive the third gear to rotate.

[0012] The linkage assembly includes a worm gear fixed to the outer wall of one of the mounting shafts, a first rotating shaft at the bottom of the base plate, a worm wheel at one end of the first rotating shaft that cooperates with the worm gear, a second rotating shaft on one side of the mixing tank, the second rotating shaft being connected to the first rotating shaft via a set of bevel gears, and the top end of the second rotating shaft being connected to the third rotating shaft via a belt drive mechanism.

[0013] The top of the base plate has multiple observation ports around the mixing tank.

[0014] A blowing mechanism for blowing away road surface cracks is provided on the top of the base plate and on one side of the mixing tank, and a flattening mechanism for flattening the concrete repair material in the cracks after patching is provided on the top of the base plate and on the other side of the mixing tank.

[0015] The outer surface of the conical sealing cap is provided with anti-slip protrusions to increase friction.

[0016] Multiple first stirring blades are fixed on the outer wall of the stirring shaft and inside the holding tank. Telescopic stirring blades that can extend and retract with the change of the inner wall of the conical hopper are fixed on the outer wall of the stirring shaft and inside the feeding pipe. Spiral stirring blades are fixed on the outer wall of the stirring shaft and inside the feeding pipe.

[0017] The technical effects achieved by this utility model are as follows:

[0018] The linkage component of this utility model, after repair, drives the stirring shaft upward via a hydraulic cylinder, causing the first gear and third gear to mesh. At this time, the stirring shaft causes the conical sealing cover to fit tightly against the sealing groove, closing the discharge port of the mixing tank. Simultaneously, when the equipment moves, the rollers rotate, driving the mounting shaft to rotate. Through the cooperation of the worm gear and worm wheel, the first rotating shaft rotates. The first rotating shaft drives the second rotating shaft to rotate via a bevel gear set. The second rotating shaft drives the third gear on the third rotating shaft to rotate via a belt drive mechanism. The third gear meshes with the first gear, driving the stirring shaft to rotate. The stirring shaft drives the first stirring blade, the spiral stirring blade, and the conical sealing cover to rotate, preventing the concrete repair material in the mixing tank from solidifying. The structure is simple. When the equipment moves, the concrete repair material in the mixing tank can be stirred by the movement of the equipment, preventing the concrete repair material in the mixing tank from solidifying during movement. This also reduces the energy consumption of the equipment operation, making it relatively energy-saving and environmentally friendly. Attached Figure Description

It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figures 1-5 As shown, a road surface maintenance device includes a base plate 1. A mixing tank 2 for loading concrete repair material is provided on the top of the base plate 1. The mixing tank 2 is integrally made from top to bottom by a holding bucket, a conical hopper, and a discharge pipe. The discharge port at the bottom of the mixing tank 2 extends below the base plate 1. A bearing 3 is rotatably installed at the center of the top of the mixing tank 2. A mixing shaft 4 extending into the mixing tank 2 is inserted into the inside of the bearing 3. A limiting groove is opened on the inner surface of the bearing 3. A limiting protrusion 5 that slides and connects with the limiting groove is fixed on the outer wall of the mixing shaft 4. A conical sealing cover 25 is rotatably installed at the bottom end of the bearing 3. A sealing groove 28 that cooperates with the conical sealing cover 25 is opened at the discharge port of the mixing tank 2. A sealing ring 26 for increasing the sealing performance of the connection between the conical sealing cover 25 and the sealing groove 28 is provided on the inner side of the sealing groove 28.

[0028] Multiple first stirring blades 23 are fixed on the outer wall of the stirring shaft 4 and inside the holding tank. Telescopic stirring blades 29, which can extend and retract with the change of the inner wall of the conical hopper, are fixed on the outer wall of the stirring shaft 4 and inside the conical hopper. The telescopic stirring blades 29 are composed of a plug rod and a sleeve. One end of the plug rod slides inside the sleeve, and the other end contacts the inner wall of the conical hopper. A spring connected to the plug rod is fixed on the inner side of the sleeve. Spiral stirring blades 24 are fixed on the outer wall of the stirring shaft 4 and inside the feeding pipe.

[0029] A hydraulic cylinder 7 for driving the stirring shaft 4 to move up and down is provided on the top of the mixing tank 2 and on one side of the stirring shaft 4. The output shaft of the hydraulic cylinder 7 is fixed with a fixed plate 6 that is rotatably connected to the stirring shaft 4. A first gear 8 is fixed on the outer wall of the stirring shaft 4 and above the fixed plate 6. A motor 9 is provided on the top of the mixing tank 2. A second gear 10 that cooperates with the first gear 8 is fixed on the output shaft of the motor 9.

[0030] A third rotating shaft is rotatably mounted on the top of the mixing tank 2, and a third gear 18 that meshes with the first gear 8 is provided on the outer wall of the mixing tank 2 above the second gear 10.

[0031] The bottom of the base plate 1 is provided with mounting shafts 11 on both sides, and rollers 19 are provided at both ends of the mounting shafts 11. The third rotating shaft is provided with a linkage component for rotating the rollers 19 to drive the third gear 18 to rotate.

[0032] The linkage assembly includes a worm gear 12 fixed to the outer wall of one of the mounting shafts 11, a first rotating shaft 13 at the bottom of the base plate 1, a worm wheel 14 that cooperates with the worm gear 12 at one end of the first rotating shaft 13, a second rotating shaft 16 on one side of the mixing tank 2, the second rotating shaft 16 being connected to the first rotating shaft 13 through a set of bevel gears 15, and the top end of the second rotating shaft 16 being connected to a third rotating shaft through a belt drive mechanism 17.

[0033] According to the above structure, when the concrete repair material in the mixing tank 2 needs to be discharged, the hydraulic cylinder 7 is activated. The hydraulic cylinder 7 drives the mixing shaft 4 to move downward through the fixing plate 6. The mixing shaft 4 drives the first gear 8 to mesh with the second gear 10. At the same time, when the hydraulic cylinder 7 drives the mixing shaft 4 to descend, it will drive the conical sealing cover 25 to move downward, causing the conical sealing cover 25 to disengage from the sealing groove 28, thus opening the discharge port of the mixing tank 2. The motor 9 is then activated, driving the mixing shaft 4 to rotate. The mixing shaft 4 drives the first mixing blade 23, the spiral mixing blade 24, and the conical sealing cover 25 to rotate, facilitating the discharge of the concrete repair material, avoiding blockage, and also preventing the concrete repair material from being stirred during discharge, thus preventing it from solidifying. After the repair is completed, the hydraulic cylinder 7 is activated again, driving the mixing shaft 4 to move upward through the fixing plate 6, causing the first gear 8 to mesh with the third gear 18. When the equipment moves, the mixing shaft 4 drives the conical sealing cover 25 to fit tightly with the sealing groove 28, and closes the discharge port of the mixing box 2. At the same time, when the equipment moves, the roller 19 will rotate, and the roller 19 will drive the mounting shaft 11 to rotate. Through the cooperation of the worm gear 12 and the worm wheel 14, the first rotating shaft 13 will rotate. The first rotating shaft 13 will drive the second rotating shaft 16 to rotate through the bevel gear set 15. The second rotating shaft 16 will drive the third gear 18 on the third rotating shaft to rotate through the belt drive mechanism 17. The third gear 18 will mesh with the first gear 8 to drive the mixing shaft 4 to rotate. The mixing shaft 4 will drive the first mixing blade 23, the spiral mixing blade 24 and the conical sealing cover 25 to rotate, which will prevent the concrete repair material in the mixing box 2 from solidifying. The structure is simple. When the equipment moves, the concrete repair material in the mixing box 2 can be stirred by moving the equipment. It is relatively energy-saving and environmentally friendly.

[0034] The first mixing blade 23 and the telescopic mixing blade 29 can mix the concrete repair material in the mixing tank 2 to prevent it from solidifying. The spiral mixing blade 24 can mix the concrete repair material in the discharge pipe. It can also facilitate the discharge of the material and prevent the concrete repair material from clogging the discharge port of the mixing tank 2, thus increasing the practicality of the equipment.

[0035] like Figure 1 As shown, the top of the base plate 1 is provided with multiple observation ports 22 around the mixing tank 2.

[0036] Based on the above structure, staff can accurately repair cracks through the observation port 22, increasing the practicality of the equipment.

[0037] like Figures 1-2 As shown, a blowing mechanism 20 for blowing away road surface cracks is provided on the top of the base plate 1 and on one side of the mixing tank 2. The blowing mechanism 20 includes a blower, and a blowing head connected to the blower is fixed below the base plate 1. This can clean the dust from the road surface cracks in advance, improving the quality of crack repair. On the top of the base plate 1 and on the other side of the mixing tank 2, a flattening mechanism 21 for flattening the concrete repair material in the cracks after patching is provided. The flattening mechanism 21 includes a cylinder, and an installation plate is fixed to the output shaft of the cylinder. Guide rods are fixed to both sides of the bottom of the installation plate. The bottom ends of the guide rods extend to the bottom of the base plate 1 and are fixed to a pressure plate. The structure is simple and easy to operate. It can flatten and compact the repaired cracks, improving the practicality of the equipment.

[0038] like Figure 3 and Figure 5 As shown, the outer surface of the conical sealing cover 25 is provided with anti-slip protrusions 27 to increase friction.

[0039] The anti-slip protrusions 27 provided by the above structure can effectively increase the friction of the conical sealing cover 25. When the conical sealing cover 25 is sealed to the sealing groove 28, it can effectively prevent the stirring shaft 4 from driving the conical sealing cover 25 to rotate, and further improve the sealing performance of the connection between the conical sealing cover 25 and the sealing groove 28.

[0040] The working principle of this utility model is as follows: When it is necessary to discharge the concrete repair material in the mixing tank 2, the hydraulic cylinder 7 is activated. The hydraulic cylinder 7 drives the mixing shaft 4 to move downward through the fixing plate 6. The mixing shaft 4 drives the first gear 8 to mesh with the second gear 10. At the same time, when the hydraulic cylinder 7 drives the mixing shaft 4 to descend, it will drive the conical sealing cover 25 to move downward, so that the conical sealing cover 25 disengages from the sealing groove 28, opening the discharge port of the mixing tank 2. The motor 9 is activated, and the motor 9 drives the mixing shaft 4 to rotate. The mixing shaft 4 drives the first mixing blade 23, the spiral mixing blade 24 and the conical sealing cover 25 to rotate, which facilitates the discharge of the concrete repair material, avoids blockage, and also avoids stirring the concrete repair material during discharge, preventing it from solidifying. After the repair is completed, the hydraulic cylinder 7 is activated to drive the mixing shaft 4 to move upward through the fixing plate 6, so that the first gear 8 meshes with the third gear 18. At this time, the stirring shaft 4 drives the conical sealing cover 25 to fit tightly with the sealing groove 28, and closes the discharge port of the mixing tank 2. At the same time, when the equipment moves, the roller 19 will rotate, and the roller 19 will drive the mounting shaft 11 to rotate. Through the cooperation of the worm gear 12 and the worm wheel 14, the first rotating shaft 13 will rotate. The first rotating shaft 13 will drive the second rotating shaft 16 to rotate through the bevel gear set 15. The second rotating shaft 16 will drive the third gear 18 on the third rotating shaft to rotate through the belt drive mechanism 17. The third gear 18 will mesh with the first gear 8 to drive the stirring shaft 4 to rotate. The stirring shaft 4 will drive the first stirring blade 23, the spiral stirring blade 24 and the conical sealing cover 25 to rotate, so as to prevent the concrete repair material in the mixing tank 2 from solidifying. The structure is simple. When the equipment moves, the concrete repair material in the mixing tank 2 can be stirred by moving the equipment. It is relatively energy-saving and environmentally friendly.

[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
