Description

Technical Field

[0001] The present invention relates to the technical field of road maintenance equipment, and more specifically to a municipal public engineering roadbed maintenance equipment. Background Art

[0002] The roadbed is the foundation of the track or road surface, and is a geotechnical structure formed by excavation or filling. The main function of the roadbed is to provide the necessary conditions for track or road surface laying and train or vehicle operation, and to bear the static and dynamic loads of the track and locomotive vehicles or road surface and traffic loads, while transmitting and diffusing the loads deep into the foundation. In the longitudinal section, the roadbed must ensure the required elevation of the line. In the plane, the roadbed is connected with bridges and tunnels to form a complete through line. In civil engineering, the roadbed occupies an important position in terms of construction quantity, land area and investment.

[0003] After a road has been opened to traffic for a period of time, whether it is an asphalt pavement or a cement pavement, some early diseases will appear to a greater or lesser extent. Common ones include cracks, potholes, rutting, looseness, surface damage, etc. Among them, cracks are one of the most common, most prone and earliest diseases of all kinds of pavement diseases. It will accompany the entire service life of the road and worsen with the increase of road age. The harm of road cracks not only affects the appearance of the road and the driving comfort. If the cracks are not sealed and repaired in time, the cracks can easily expand further during the process of opening to traffic, allowing rainwater and other debris to enter the surface structure and roadbed along the cracks, causing structural damage to the road, resulting in a decrease in the bearing capacity of the roadbed, accelerating local or large-scale damage to the road surface, and shortening the service life of the road.

[0004] Most of the existing roadbed maintenance equipment pours the prepared asphalt mixture into a storage barrel and seals the storage barrel to place the asphalt mixture in a relatively closed space, thereby reducing its own heat dissipation, and then gradually fills the cracks. As the repair time increases, the temperature of the asphalt mixture near the wall of the storage barrel will gradually decrease, causing the asphalt mixture near the wall of the storage barrel to stick to each other and agglomerate, changing the shape of the asphalt mixture during repair, so that the asphalt mixture cannot better fit the cracks, thereby reducing the repair effect on the highway;

[0005] Moreover, most existing asphalt mixtures require specific mixing equipment for mixing and preparation. Since the road repair device only needs to repair cracks, the amount of asphalt mixture used is relatively small. If a separate mixing equipment is configured to mix and prepare the asphalt mixture, unnecessary production costs will be increased and the practical performance of the device will be poor.

[0006] On the other hand, most of the existing roadbed maintenance equipment uses visual inspection to detect cracks on the road surface and then repairs them. This method is simple and intuitive, but for large-scale damage detection, the workload is large and has a certain degree of subjectivity. Not only is the efficiency extremely low, but the repair strength is also unsatisfactory.

[0007] To this end, we designed a municipal public engineering roadbed maintenance equipment to provide another technical solution to the above technical problems. Summary of the invention

[0075] A driven gear 3 47 is meshed with the side of the driving gear 2 44 away from the driven gear 2 43, a rotating shaft 5 48 is fixedly arranged in the middle of the driven gear 3 47, and both ends of the rotating shaft 5 48 are respectively rotatably connected with the inner wall of the protective cover 1 5, a driving gear 3 49 is fixedly arranged on the side of the rotating shaft 5 48 away from the driven gear 3 47, and two transmission gears 50 for changing direction are sequentially distributed on the side of the driving gear 3 49 close to the driven gear 2 43, and the two transmission gears 50 are respectively meshed with the driving gear 3 49 and the driven gear 2 43 and are rotatably connected in the protective cover 1 5, a photoelectric sensor transmitter 51 is fixedly arranged on the top of the protective cover 1 5, and a photoelectric sensor receiver 52 matched with the photoelectric sensor transmitter 51 is fixedly arranged on the top of the storage barrel 6;

[0076] By adopting the above technical solution, the staff only needs to pour asphalt, coarse aggregate, fine aggregate and mineral powder into the storage barrel 6, and start the drive motor 3 46 to drive the drive gear 2 44 to rotate, thereby driving the driven gear 2 43 meshing with the drive gear 2 44 to rotate, and the stirring shaft 1 40 fixedly connected in the middle thereof rotates under the drive of the driven gear 2 43, thereby driving the stirring blades to stir on the inner wall of the storage barrel 6 and rub against the inner wall of the storage barrel 6, thereby increasing the temperature inside the storage barrel 6, increasing the molecular activity inside the asphalt, and improving the preparation efficiency of the asphalt mixture. While the stirring shaft 1 40 rotates, the drive gear The driven gear three 47 meshed with the other side of the wheel two 44 rotates accordingly, and drives the driving gear three 49 to rotate through the rotating shaft five 48. While the driving gear three 49 rotates, the driven gear two 43 on the other side of the storage barrel 6 is driven to rotate through the two transmission gears 50 for changing direction meshed with one side thereof, and the storage barrel 6 is driven to rotate in the opposite direction to the stirring shaft one 40 through the rotating shaft four 42 fixed in the middle of the driven gear two 43, thereby accelerating the preparation speed of the asphalt mixture in the storage barrel 6, and the temperature generated by the friction between the stirring blades and the inner wall of the storage barrel 6 in the mixing barrel, further improving the preparation speed of the asphalt mixture;

[0077] Through the design of the protective cover 5, the parts of the asphalt mixing mechanism 7 exposed on the engineering vehicle body 1 are protected to avoid wear caused by direct contact between external dust or other solid impurities and the parts, effectively extending the service life of the asphalt mixing mechanism 7. At the same time, through the design of the photoelectric sensor transmitter 51 and the photoelectric sensor receiver 52, the position of the storage barrel 6 when it stops is controlled so that the subsequent processes can run steadily.

[0078] See also Fig. 9 A friction plate 53 that contacts the inner wall of the material storage barrel 6 is movably provided on the outer side of the stirring blade 1 41 and the stirring blade 2 82, and a limit installation cavity 54 that matches the friction plate 53 is provided on the stirring blade 1 41 and the stirring blade 2 82, and a plurality of compression springs 55 are fixedly connected to the inner side of the friction plate 53, and one end of the compression spring 55 away from the friction plate 53 is fixedly connected to the inner wall of the installation hole;

[0079] By adopting the above technical solution, it is convenient to make up the length of the friction plate 53 lost by the friction between the friction plate 53 and the inner wall of the storage barrel 6, so that the friction plate 53 can always abut against the inner wall of the storage barrel 6, ensuring the stable operation of the asphalt mixing mechanism 7;

[0080] It should be noted that, in the present embodiment, the friction plate 53 and the inner wall of the storage barrel 6 are both made of 2A12 wear-resistant aluminum alloy material, thereby ensuring the corrosion resistance of the friction plate 53 and the inner wall of the storage barrel 6 while increasing the temperature generated by the friction between the friction plate 53 and the inner wall of the storage barrel 6, so that the asphalt mixture in the storage barrel 6 can always maintain a high fluidity, thereby improving the practical performance of the device.

[0081] Please refer to 10- Fig.11 The upper and lower ends of the storage barrel 6 are respectively provided with a feed port 56 and a discharge port 57, and the protective cover 5 is provided with a feed port 58 matching the feed port 56, and the external thread of the feed port 58 is connected with a sealing cover 59;

[0082] A mounting block 60 is fixedly provided on one side of the feed port 1 56 and the feed port 58. A blocking component 61 for blocking the feed port 1 56 and the discharge port 57 is provided inside the mounting block 60. The blocking components 61 at the feed port 1 56 and the discharge port 57 are designed to be symmetrical up and down. The blocking component 61 includes a blocking plate 62 slidably arranged inside the mounting block 60. An opening 63 matching the blocking plate 62 is opened on the feed port 1 56 and the discharge port 57. A slider 64 is fixedly provided on the side of the blocking plate 62 away from the storage barrel 6. The mounting block The interior of the second block 60 is provided with a slide groove 65 matching the slider 64, the middle of the slider 64 is rotatably connected to the third link 66, the side of the third link 66 away from the slider 64 is rotatably connected to the fourth link 67, the end of the fourth link 67 away from the third link 66 is rotatably connected to the trigger pressure plate 68, the mounting block 60 is provided with a concave hole 69 matching the trigger pressure plate 68, the interior of the mounting block 60 is rotatably connected to an elastic steel coil 70 matching the blocking plate 62, and the opening 63 end of the elastic steel coil 70 is fixedly connected to the trigger pressure plate 68;

[0083] By adopting the above technical solution, when the staff needs to pour asphalt, coarse aggregate, fine aggregate and mineral powder into the storage barrel 6, they only need to insert the hopper along the feeding port 58 into the feed port 1 56, and the trigger pressure plate 68 can be squeezed by the bottom end of the hopper to drive the trigger pressure plate 68 to move downward. During the downward movement of the trigger pressure plate 68, the connecting rod 4 67 rotatably connected thereto tilts upward and swings, and drives the slider 64 to slide inward along the slide groove 65 through the connecting rod 3 66, so that the blocking plate 62 fixedly connected to the top of the slider 64 gradually retracts into the mounting block 2 60 along the opening 63. When the trigger pressure plate 68 moves down to the concave hole 69, the blocking plate 62 is completely retracted into the mounting block 2 60. At this time, the asphalt, coarse aggregate, fine aggregate and mineral powder can be poured into the feed port 1 56 along the hopper.

[0084] At the same time, during the process of the sealing plate 62 contracting inwardly, the elastic steel coil 70 fixedly connected to the bottom of the trigger pressure plate 68 extends along with the movement of the trigger pressure plate 68, thereby sealing the hollow area of ​​the mounting block 2 60, preventing asphalt, coarse aggregate, fine aggregate and mineral powder from entering the mounting block 2 60 during pouring, thereby affecting the normal use of the sealing assembly 61.

[0085] See also Figure 12-Figure 15 The crack repair mechanism 8 includes an auxiliary discharge box 71 arranged at the bottom of the storage barrel 6, a feed port 72 is provided at the top of the auxiliary discharge box 71, a cylindrical ring 73 for pressing the trigger pressure plate 68 is fixedly provided inside the feed port 72, and a moving block 74 is fixedly provided on both sides of the auxiliary discharge box 71, and a moving groove 75 matching the moving block 74 is provided inside the engineering vehicle body 1, a screw 76 and a guide limit rod 77 are penetrated on the moving block 74, and the screw 76 is threadedly connected to the moving block 74, and both ends of the screw 76 and the guide limit rod 77 are rotatably connected to the inner wall of the moving groove 75, a pulley 78 is fixed at the bottom end of the screw 76, and a transmission belt 79 is sleeved on the outside of the pulley 78, and the bottom end of one of the screws 76 penetrates the moving groove 75 and is connected to a driving motor 80 for driving the screw 76;

[0086] By adopting the above technical scheme, when material needs to be fed inside the auxiliary discharge box 71, the staff controls the drive motor 4 80 in the cab to start, drives the screw 76 fixedly connected to its output end to rotate, and drives the screw 76 on the other side to rotate synchronously through the pulley 78 and the transmission belt 79, thereby controlling the auxiliary discharge box 71 to move horizontally upward, so that the cylindrical ring 2 73 at the top of the auxiliary discharge box 71 is gradually inserted into the discharge port 57, and the trigger pressure plate 68 in the discharge port 57 is squeezed, so that the sealing plate 62 in the discharge port 57 is retracted into the mounting block 2 60, so that the discharge port 57 is connected with the feed port 2 72 through the cylindrical ring 2 73, thereby realizing the feeding of the auxiliary discharge box 71.

[0087] See also Fig.12 The auxiliary discharge box 71 is internally rotatably connected with a stirring shaft 81, and the external fixed sleeve of the stirring shaft 81 is provided with a plurality of stirring blades 82. One end of the stirring shaft 81 passes through the auxiliary discharge box 71 and is connected with a driving motor 83. The driving motor 83 is embedded in one of the moving blocks 74.

[0088] By adopting the above technical solution, when the auxiliary discharge box 71 is connected to the storage barrel 6 for filling the asphalt mixture, the staff controls the drive motor 5 83 in the cab to start, so that the stirring shaft 2 81 drives the stirring blade 2 82 to stir inside the auxiliary discharge box 71, thereby accelerating the fluidity of the asphalt mixture in the auxiliary discharge box 71, and further improving the efficiency of repairing road cracks;

[0089] It should be noted that, in the present embodiment, in order to prevent the asphalt mixture from solidifying and sticking inside the storage barrel 6 and the auxiliary discharge box 71, the staff can control the drive motor three 46 and the drive motor five 83 to start from time to time, so that the stirring shaft one 40 and the stirring shaft two 81 drive the stirring blade one 41 and the stirring blade two 82 to stir inside the storage barrel 6 and the auxiliary discharge box 71, thereby effectively preventing the asphalt mixture from solidifying and sticking inside the storage barrel 6 and the auxiliary discharge box 71, and improving the practical performance of the device.

[0090] See also Figure 12-15 , a plurality of leakage holes 84 are provided at the bottom of the auxiliary discharge box 71, a sleeve rod 85 is connected to the bottom end of the plurality of leakage holes 84, a wedge-shaped repair sleeve 86 is movably connected inside the sleeve rod 85, a repair ball 87 is connected to the bottom end of the wedge-shaped repair sleeve 86, a plurality of wear-resistant particles 88 and leakage repair holes 89 are uniformly distributed on the outside of the repair ball 87, a leakage ring 90 is fixedly provided at the top end of the wedge-shaped repair sleeve 86, the holes on the leakage ring 90 are connected to the inner hole of the wedge-shaped repair sleeve 86, a wedge-shaped blocking column 91 matching the top end of the sleeve rod 85 is fixedly provided in the middle of the leakage ring 90, a groove 92 is symmetrically provided inside the top end of the sleeve rod 85, a signal trigger switch 93 is fixedly provided inside the groove 92, and an arc-shaped spring piece 94 for pressing the signal trigger switch 93 is fixedly provided inside the groove 92;

[0091] By adopting the above technical solution, when the staff drives the engineering vehicle body 1 on the road, the wedge-shaped repair sleeve 86 and the repair ball 87 always contact the road surface under the action of gravity. At this time, the leakage ring 90 and the wedge-shaped blocking column 91 at the top of the wedge-shaped repair sleeve 86 are movably inserted into the top of the sleeve rod 85 and abut against the inner wall of the sleeve rod 85 to block the inside of the sleeve rod 85, thereby preventing the asphalt mixture in the auxiliary discharge box 71 from flowing into the repair ball 87 through the sleeve rod 85 and the wedge-shaped repair sleeve 86 to cause unnecessary loss. When there are cracks on the road surface, the wedge-shaped repair sleeve 86 and the repair ball 87 fall into the cracks under the action of their own gravity. At this time, the leakage ring 90 and the wedge-shaped blocking column 91 at the top of the wedge-shaped repair sleeve 86 move downward and gradually separate from the inner wall of the top of the sleeve rod 85. As the wedge-shaped plugging column 91 moves downward, the top of the wedge-shaped plugging column 91 gradually squeezes the arc-shaped spring piece 94, causing it to shrink into the groove 92 and press the signal trigger switch 93, so that the engineering vehicle body 1 stops driving, and then the wedge-shaped repair sleeve 86 and the repair ball 87 continue to move downward under the action of gravity and collide with the bottom wall of the crack. In this process, the asphalt mixture in the auxiliary discharge box 71 gradually flows into the repair ball 87 through the leakage hole 84, the sleeve rod 85, the leakage ring 90 and the wedge-shaped repair sleeve 86, and flows into the gap through the repair leakage hole 89 opened on the repair ball 87 to repair the crack. In the process of continuously filling and repairing the crack, the repair ball 87 and the wedge-shaped repair sleeve 86 gradually float up with the continuous filling of the asphalt mixture, and re-block the sleeve rod 85 to complete the filling and repair of the road surface crack.

[0092] It should be noted that, in this embodiment, the signal trigger switch 93 is electrically connected to the controller in the cab of the engineering vehicle body 1. Through this design, it is convenient to control the engineering vehicle body 1 to stop as soon as the repair ball 87 enters the crack through the electrical connection between the signal trigger switch 93 and the controller, thereby improving the accuracy of crack repair.

[0093] Method of use: When driving the engineering vehicle body 1 to work on the road, the staff in the cab observes whether there are cracks on the road ahead through the images captured by the infrared camera 18. If there are cracks on the road ahead, the staff can reduce the forward speed of the engineering vehicle body 1 in the cab and strengthen the suction force of the dust suction motor 33 so that the cleaning dust suction head can suck out the solid impurities hidden in the cracks. As the engineering vehicle body 1 continues to move forward, the wedge-shaped repair sleeve 86 and the repair ball 87 fall into the crack under the action of their own gravity. At this time, the leakage ring 90 and the wedge-shaped blocking column 91 at the top of the wedge-shaped repair sleeve 86 move downward and gradually separate from the inner wall of the top of the sleeve rod 85. As the leakage ring 90 and the wedge-shaped blocking column 91 move downward, the top of the wedge-shaped blocking column 91 gradually squeezes the arc-shaped spring piece 94, causing it to shrink into the groove 92 and press the signal trigger switch 93, so that the engineering vehicle body 1 stops driving;

[0094] At this time, the staff controls the drive motor three 46 and the drive motor five 83 to start, so that the stirring shaft one 40 and the stirring shaft two 81 drive the stirring blade one 41 and the stirring blade two 82 to stir inside the storage barrel 6 and the auxiliary discharge box 71 to accelerate the fluidity of the asphalt mixture. In this process, the staff controls the drive motor four 80 to start, so as to drive the screw 76 fixedly connected to the output end of the drive motor four 80 to rotate, and through the pulley 78 and the transmission belt 79, drives the screw 76 on the other side to rotate synchronously, thereby controlling the auxiliary discharge box 71 to move horizontally upward, so that the cylindrical ring two 73 at the top of the auxiliary discharge box 71 is gradually inserted into the discharge port 57, and the trigger pressure plate 68 in the discharge port 57 is squeezed, so that the sealing plate 62 in the discharge port 57 is retracted into the mounting block two 60, so that the discharge port 57 and the feed port two 72 are connected through the cylindrical ring two 73, thereby completing the supply of materials from the storage barrel 6 to the auxiliary discharge box 71;

[0095] Then, the wedge-shaped repair sleeve 86 and the repair ball 87 continue to move downward under the action of gravity and collide with the bottom wall of the crack. During this process, the asphalt mixture in the auxiliary discharge box 71 gradually flows into the repair ball 87 through the leakage hole 84, the sleeve rod 85, the leakage ring 90 and the wedge-shaped repair sleeve 86, and flows into the gap through the repair leakage hole 89 opened on the repair ball 87 to repair the crack. In the process of continuously filling and repairing the crack, the repair ball 87 and the wedge-shaped repair sleeve 86 gradually float up with the continuous filling of the asphalt mixture, and re-block the sleeve rod 85 to complete the filling and repair of the road surface cracks.

[0096] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
