[0002] Over long-term use, highways are prone to damage such as cracks, potholes, and settlement due to factors such as vehicle loads and the natural environment. If not repaired in time, these problems can not only affect driving comfort but also potentially lead to traffic accidents.

[0003] The basic equipment for highway pavement repair includes milling equipment, filling equipment, and compaction equipment. The milling equipment is used to clean the damaged pavement, the filling equipment is used to fill the damaged pavement with asphalt and concrete spraying material, and the compaction equipment is used to compact the pavement material.

[0004] Existing road repair equipment often suffers from limited functionality, typically only capable of performing single processes such as milling, filling, and compaction. The repair process requires frequent equipment changes or manual tool adjustments, resulting in low repair efficiency. Furthermore, the equipment is complex to operate, has poor adaptability, and struggles to meet the repair needs of different types of road damage. Therefore, a highway road repair equipment is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a highway pavement repair device, which aims to solve the problem that existing pavement repair devices have limited functions and are difficult to adapt to different types of pavement damage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a highway pavement repair device, comprising a switching base, a switching shaft rotatably connected to one side of the switching base, a plurality of repair components arranged in a circular array on the switching shaft, a driving device on the other side of the switching base, the driving device being used to drive the switching shaft to rotate, a rocker arm fixedly connected to the switching base, and an installation roller fixedly connected to the rocker arm.

[0007] As a further description of the above technical solution: the repair component includes a connecting frame, which is fixedly connected to the switching shaft. A T-shaped limiting slide rod is slidably connected to the upper part of the connecting frame. A mounting frame is fixedly connected to the end of the T-shaped limiting slide rod, and a repair component is fixedly connected to the mounting frame.

[0008] As a further description of the above technical solution: a pressure spring is fixedly connected to the mounting bracket, a connecting shaft seat is fixedly connected to the end of the pressure spring, and the end of the connecting shaft seat is fixedly connected to the switching shaft.

[0009] As a further description of the above technical solution: the switching base has a circular groove and a linear groove on the side near the switching shaft.

[0010] As a further description of the above technical solution: a limiting crank is fixedly connected to the mounting bracket, and the end of the limiting crank is slidably connected to the inner wall of the circular groove.

[0011] As a further description of the above technical solution: the driving device includes a connecting plate, the surface of the connecting plate is fixedly connected to the surface of the rocker arm, a control motor is fixedly connected to the connecting plate, a connecting rod is fixedly connected to the output shaft of the control motor, a worm is fixedly connected to the end of the connecting rod, and a worm wheel meshes with the surface of the worm.

[0012] As a further description of the above technical solution: a protective base is fixedly connected to the switching base, and the worm and worm wheel both rotate within the protective base.

[0013] As a further description of the above technical solution: the end of the switching shaft passes through the protective base and is fixedly connected to the inside of the worm gear.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the rocker arm and installation roller adjust the switching shaft and three sets of repair components on the two switching bases to a suitable working posture. The three repair components are rotated and switched by the drive device, and the corresponding repair component is rotated to the working position for corresponding repair. This further achieves the effect of automatic switching of different repair components, meeting various repair needs such as crack cleaning, pothole filling, and road compaction. It achieves the purpose of adaptive repair for different types of road damage, realizing the integration of multiple repair functions such as milling, filling, and compaction, eliminating the need for frequent equipment changes and greatly improving repair efficiency.

[0016] 2. In this utility model, when the corresponding repair component rotates to the linear groove, the pressure spring on the corresponding mounting bracket can be compressed. The pressure spring automatically extends and retracts according to the road surface undulations and slope. With the guiding effect of the T-shaped limit slide rod, it ensures that the repair component always applies stable pressure to the damaged part. The setting of the limit crank rod allows the repair component in operation to drive the corresponding limit crank rod to slide in the linear groove according to the road surface conditions, thereby performing pressure adaptive repair work. The other two repair components in the non-operating state are limited in the circular groove by the limit crank rod, thereby achieving the effect of stabilizing the repair components in the non-operating state.

[0024] 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.

[0025] Reference Figures 1-2The present invention provides an embodiment of a highway pavement repair device, comprising two symmetrical switching bases 1, a switching shaft 2 rotatably connected between the inner sides of the two switching bases 1, and three sets of circularly arrayed repair components 3 arranged on the switching shaft 2. The three repair components 3 are respectively equipped with milling cutters, leveling scrapers and compaction wheels, realizing the effect of switching multiple repair processes. A driving device 4 is arranged on the outer side of the switching base 1, which is used to drive the switching shaft 2 to rotate. A rocker arm 5 is fixedly connected to the switching base 1, and an installation roller 6 is fixedly connected to the rocker arm 5. The entire device is mounted on a repair vehicle via the installation roller 6 on the rocker arm 5. The repair vehicle adjusts the switching shaft 2 and the three sets of repair components 3 on the two switching bases 1 to a suitable working posture by driving the rocker arm 5 and the installation roller 6. The driving device 4 causes the three repair components 3 to rotate and switch, rotating the repair component 3 with the corresponding function to the working position for corresponding repair, further achieving the effect of automatic switching of different repair components 3, meeting multiple repair needs such as crack cleaning, pothole filling and pavement compaction, and achieving the purpose of adaptive repair for different types of pavement damage.

[0026] Reference Figure 3 The repair component 3 includes a connecting frame 31, which is fixedly connected to the switching shaft 2. A sliding hole is provided on the connecting frame 31, and a T-shaped limiting slide rod 32 is slidably connected within the sliding hole. A mounting frame 33 is welded to the end of the T-shaped limiting slide rod 32. The mounting frame 33 is detachably connected to the corresponding repair component via bolts, facilitating the replacement and maintenance of the repair component. A pressure spring 34 is welded to the mounting frame 33, and a connecting shaft seat 35 is welded to the end of the pressure spring 34. The connecting shaft seat 35 is fixed to the switching shaft 2 via bolts. The pressure spring 34 is initially in a slightly compressed state to ensure the initial contact pressure between the repair component and the road surface. The control system sets the repair process, and the drive device 4 starts according to the preset program, driving the switching shaft 2 to rotate and switch the corresponding repair component 3 to the working position. During the operation, the pressure spring 34 adjusts the repair pressure in real time to ensure the repair effect. When switching processes, the drive device 4 rotates in the opposite direction to achieve rapid switching of the next repair component 3. The entire process is highly automated and suitable for efficient repair of various types of road surface damage on highways.

[0027] Reference Figures 3-4The switching base 1 has a circular groove 11 and a linear groove 12 on one side near the switching shaft 2. A limiting crank 36 is fixedly connected to the mounting bracket 33. The end of the limiting crank 36 is slidably connected to the inner wall of the circular groove 11. The linear groove 12 is distributed in a state perpendicular to the ground. When the corresponding repair component 3 rotates to the linear groove 12, the pressure spring 34 on the corresponding mounting bracket 33 can be compressed. The pressure spring 34 automatically extends and retracts according to the road surface undulation and slope. With the guiding effect of the T-shaped limiting slide bar 32, it ensures that the repair component always applies stable pressure to the damaged part. The setting of the limiting crank 36 allows the repair component 3 in operation to slide the corresponding limiting crank 36 in the linear groove 12 according to the road surface conditions, and then perform pressure adaptive repair work. The other two repair components 3 in the non-operating state are limited in the circular groove 11 by the limiting crank 36, thereby achieving the effect of stabilizing the repair component 3 in the non-operating state.

[0028] Reference Figure 5 The drive device 4 includes a connecting plate 41, which is fixedly connected to the surface of the rocker arm 5 by bolts. A control motor 42 is fixedly installed on the connecting plate 41 by bolts. The control motor 42 is a servo motor, which can achieve precise speed control. The output shaft of the control motor 42 is fixedly connected to a connecting rod 43 by a coupling. A worm gear 44 is welded and fixed to the end of the connecting rod 43. A worm wheel 45 meshes with the surface of the worm gear 44. A protective base 7 is welded to the switching base 1. The worm gear 44 and the worm wheel 45 rotate within the protective base 7. The end of the switching shaft 2 passes through the protective base 7 and is fixedly connected to the inside of the worm wheel 45.

[0029] Working principle: First, according to the type of road damage, the control motor 42 in the drive device 4 is started by the control system. The control motor 42 drives the connecting rod 43 and the worm gear 44 to rotate. The worm gear 44 drives the worm wheel 45 and the switching shaft 2 to rotate, rotating the corresponding repair component 3 to the working position. At this time, the limiting crank 36 slides along the circular groove 11 on the switching base 1 into the linear groove 12. The repair vehicle drives the rocker arm 5 and the mounting roller 6 through the drive component, so that the three sets of repair components 3 move to the appropriate working posture. The pressure spring 34 in the repair component 3 at the working position can automatically extend and retract according to the road surface undulation and slope. The corresponding limiting crank 36 slides adaptively back and forth towards the switching shaft 2 in the linear groove 12. The other two repair components 3 at the non-working position are fixed in the circular groove 11 by the limiting crank 36.

[0030] During operation, the repaired parts are always subjected to stable pressure by the pressure spring 34. When it is necessary to switch repair processes, the repair vehicle drives the rocker arm 5 through the drive component to move the three sets of repair components 3 into a non-operational posture. The drive device 4 is restarted and drives the repair components 3 to rotate through the switching shaft 2, so that the repair components 3 of the next function enter the work station, realizing continuous repair operation.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
