Description

Technical Field

[0002] Municipal road surface crack repair refers to the process of detecting, assessing, and repairing cracks in concrete or asphalt pavements in public places such as urban roads, squares, and parking lots. The main purpose of crack repair is to restore the smoothness of the road surface, extend its service life, and ensure driving safety and comfort. In the process of municipal road surface crack repair, repair materials need to be filled into the cracks. The existing technology, authorized by publication number CN222043830, involves the use of repair materials to fill and repair the cracks. U proposes a municipal road surface crack filling device, including a filling device and auxiliary components. The filling device is also fixedly installed with a material cylinder. The auxiliary components include a fixed frame fixedly installed at the center of the rear end of the filling device, and a nozzle installed at the front end of the fixed frame at the rear end of the filling device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This embodiment provides a technical solution: a municipal road surface crack repair and filling device, including a trolley 1, which facilitates the movement of the municipal road surface crack repair and filling device along the crack trajectory. The front end of the upper surface of the trolley 1 is provided with a repair material cylinder 2, which provides space for storing repair materials. The rear end of the trolley 1 is slidably connected to a filling tube 3, which fills the repair materials into the crack. The handle surface of the trolley 1 is provided with a microcontroller 16, which controls the start and stop of the entire device. The placement plate surface of the trolley 1 is provided with a conveying pump 12, which provides power for conveying repair materials. The input end of the microcontroller 16 is electrically connected to an external power source. The conveying pump 12 is connected in series between the inlet of the filling tube 3 and the outlet of the repair material cylinder 2. The input end of the conveying pump 12 is electrically connected to the output end of the microcontroller 16. It also includes an adjustment mechanism 4.

[0021] Adjustment mechanism 4 includes a sliding frame 41, a slider 42, a right adjusting slider 43, and a left adjusting slider 44. The sliding frame 41 is longitudinally slidably connected to the lower surface of the trolley 1. Inside the sliding frame 41, from left to right, the left adjusting slider 44 and the right adjusting slider 43 are slidably connected. The outer arc surface of the left adjusting slider 44 is laterally slidably connected to the slider 42. The slider 42 and the right adjusting slider 43 are elastically limited. The sliding frame 41 and the trolley 1 are also elastically limited. The filling tube 3 is vertically slidably connected to the slider 42. During the filling process, personnel push the trolley 1 to move the filling tube 3 along the crack trajectory, changing the filling position. During the movement, when there is a deviation between the movement of the filling tube 3 and the crack trajectory, the slider 42 and the right adjusting slider 43 are used to adjust the position. The elastic limit between the adjusting sliders 43 is adjusted to apply a rightward force to the slider 42, pushing the slider 42 to move to the right. The convex ring at the right end of the outer arc surface of the internal threaded tube of the left adjusting slider 44 applies a leftward force to the slider 42, pushing the slider 42 to move to the left, thus adjusting the left and right positions of the filling tube 3. The adjusting mechanism 4 also includes a contact sensor 45, which is located on the right inner wall of the sliding frame 41. The output end of the contact sensor 45 is electrically connected to the input end of the microcontroller 16. When the right adjusting slider 43 contacts the detection end of the contact sensor 45, it indicates that the slider 42 needs to be adjusted to the left. The lower surface of the trolley 1 is provided with guide frames 5. The sliding frame 41 is longitudinally slidably connected between the outer arc surfaces of the guide columns of the two guide frames 5. Springs 6 are provided between the support plate and the sliding frame 41. The springs 6 are movably sleeved on the outer arc surface of the guide column of the guide frame 5. When there is a deviation between the movement of the filling tube 3 and the trajectory of the crack, the road surface will generate resistance to the movement of the filling tube 3, overcoming the elastic force of the springs 6, and pushing the sliding frame 41 to slide backward on the outer arc surface of the guide column of the guide frame 5. When the left and right positions of the filling tube 3 are accurate, under the action of the elastic force of the springs 6, the sliding frame 41 is pushed to slide relative to the trolley 1, so that the filling tube 3 moves accurately along the trajectory of the crack. The lower surface of the trolley 1 is provided with a slanted groove frame 8, and the upper surface of the right adjusting slider 43 is provided with a sliding column 7. The sliding column 7 is slidably connected to the inside of the slanted groove of the slanted groove frame 8. A tension spring 9 is provided between the slider 42 and the right adjusting slider 43. The tension spring 9 is movably sleeved on the left The sliding frame 41 slides backward on the outer arc surface of the guide column of the guide frame 5, and the sliding column 7 slides inside the inclined groove of the inclined groove frame 8, causing the right adjusting slider 43 to slide to the right inside the sliding frame 41. This pulls the tension spring 9 to extend, and under the elastic force of the tension spring 9, a rightward force is applied to the slider 42. The system also includes a screw 10, which is rotatably connected between the left and right inner walls of the sliding frame 41. The inner threaded tube in the middle of the left adjusting slider 44 is threadedly connected to the screw 10, and the clearance hole in the middle of the right adjusting slider 43 is slidably connected to the screw 10. A motor 11 is located on the left side of the sliding frame 41, and the output shaft of the motor 11 is fixedly connected to the screw 10. The input end of the motor 11 is electrically connected to the output end of the microcontroller 16.Motor 11, screw 10, sliding frame 41, and guide frame 5 are all located inside the protective shell on the lower surface of the trolley 1. When motor 11 is started, the output shaft of motor 11 drives screw 10 to rotate. Screw 10 is connected to the internal threaded tube of left adjusting slider 44 through the screw thread, causing left adjusting slider 44 to move to the left. The internal threaded tube slides relative to slider 42. The convex ring at the right end of the outer arc surface of the internal threaded tube applies a leftward force to slider 42, pushing slider 42 and filling tube 3 to move to the left. The rear end of slider 42 is provided with a sliding cylinder 13. The screw hole at the upper end of the sliding cylinder 13 is internally threaded to an adjusting screw 14. The upper end of the outer arc surface of the adjusting screw 14 is rotatably connected to a connecting plate 15. The front end of the connecting plate 15 is fixedly connected to the outer arc surface of the filling tube 3. The lower end of the filling tube 3 passes through the guide hole on the upper surface of the slider 42. Rotating the adjusting screw 14 causes it to move downwards through the threaded connection between the adjusting screw 14 and the screw hole of the slider 13. The adjusting screw 14 rotates relative to the connecting plate 15, and under the connection of the connecting plate 15, it causes the filling tube 3 to move downwards, so that the lower end of the filling tube 3 is inserted into the crack in the municipal road surface, thus adjusting the vertical position of the filling tube 3. A corrugated pipe is provided between the lower surface of the connecting plate 15 and the upper surface of the slider 13. The corrugated pipe is movably sleeved on the outer arc surface of the adjusting screw 14, providing protection for the adjusting screw 14.

[0022] The working principle of the municipal road surface crack repair and filling device provided by this utility model is as follows: During the municipal road surface crack repair process, firstly, the adjusting screw 14 is rotated. Through the threaded connection between the adjusting screw 14 and the screw hole of the slide cylinder 13, the adjusting screw 14 is driven to move downward. The adjusting screw 14 rotates relative to the connecting plate 15. Under the connection of the connecting plate 15, the filling tube 3 is driven to move downward, so that the lower end of the filling tube 3 is inserted into the crack of the municipal road surface. Then, the single-chip microcomputer 16 starts the material pump 12, so that the repair material in the repair cylinder 2 flows out from the filling tube 3 into the road surface crack to fill the municipal road surface crack. During the filling process, personnel push the trolley 1 to move the filling tube. 3. The filling tube 3 moves along the crack trajectory, changing the filling position. During the movement, when the movement of the filling tube 3 deviates from the crack trajectory, the road surface will generate resistance to the movement of the filling tube 3, overcoming the elastic force of the spring 6, and pushing the sliding frame 41 to slide backward on the outer arc surface of the guide column of the guide frame 5. At this time, the sliding column 7 slides inside the inclined groove of the inclined groove frame 8, driving the right adjusting slider 43 to slide to the right inside the sliding frame 41, pulling the tension spring 9 to extend. Under the elastic force of the tension spring 9, a rightward force is applied to the slider 42. When the movement of the filling tube 3 deviates to the left from the crack trajectory, there is space for the filling tube 3 to move to the right. At this time, under the rightward force applied to the slider 42 by the tension spring 9, the slider 42 is moved to the right. Block 42 moves the filling tube 3 to the right. When the filling tube 3 moves to the accurate position, under the elastic force of spring 6, it pushes the sliding frame 41 to slide relative to the trolley 1, so that the filling tube 3 moves accurately along the trajectory of the crack. When the movement of the filling tube 3 deviates to the right from the trajectory of the crack, the filling tube 3 cannot move to the right. At this time, as the right adjusting slider 43 moves, the tension spring 9 will be stretched. When the right adjusting slider 43 contacts the detection end of the contact sensor 45, the contact sensor 45 sends a signal to the microcontroller 16. The microcontroller 16 controls the motor 11 to start. The output shaft of the motor 11 drives the screw 10 to rotate. The screw 10 is connected to the internal thread of the left adjusting slider 44, driving the left adjusting slider 44. Slider 44 moves to the left, and the internal threaded tube slides relative to slider 42. The convex ring at the right end of the outer arc surface of the internal threaded tube applies a leftward force to slider 42, pushing slider 42 and filling tube 3 to move to the left. When the filling tube 3 moves to the accurate position, under the elastic force of spring 6, it pushes the sliding frame 41 to slide relative to the trolley 1, so that the filling tube 3 moves accurately along the crack trajectory. At this time, the right adjusting slider 43 separates from the detection end of the contact sensor 45, stops the rotation of screw 10, and at the same time, screw 10 reverses, driving the left adjusting slider 44 to reset. The above operation is repeated, and the left and right positions of filling tube 3 are automatically adjusted according to the deviation of the moving trajectory of filling tube 3 from the crack trajectory.

[0023] It is worth noting that the microcontroller 16 disclosed in the above embodiments can be an AT89C4051 microcontroller. The feed pump 12, contact sensor 45 and motor 11 can be freely configured according to the actual application scenario. The feed pump 12 can be a 2ZBQ-30 / 3 grouting pump, the contact sensor 45 can be an M109-RM contact sensor, and the motor 11 can be a 5IK40RGU-CF motor. The microcontroller 16 controls the operation of the feed pump 12, contact sensor 45 and motor 11 using methods commonly used in the prior art.

[0024] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
