Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to a road cavity detection device. Background Art

[0002] Road holes are spaces or holes that appear below the road surface. This can be caused by a variety of reasons, such as poor material quality, wear and tear caused by frequent vehicle traffic, and underground water pipe leakage. Road holes pose a serious threat to driving safety as they can cause road surface collapse, leading to traffic accidents.

[0003] Road holes are a serious traffic safety hazard that requires regular inspection and timely repair. In the existing technology, ground penetrating radar is usually used to detect road holes. Ground penetrating radar is an effective means of detecting underground targets developed in recent decades. It is a non-destructive detection technology. Compared with other conventional underground detection methods, it has the advantages of fast detection speed, continuous detection process, high resolution, convenient and flexible operation, and low detection cost. It is increasingly widely used in the field of engineering survey. Ground penetrating radar is a detection device that uses an antenna to transmit and receive high-frequency electromagnetic waves to detect the material properties and distribution patterns inside the medium.

[0004] At present, there are cart-type ground penetrating radars on the market, which are mainly moved by manual pushing. However, the manual pushing method is slow, resulting in slow detection speed, which affects the efficiency of detecting road holes. And because the transmitter on the ground penetrating radar is close to the ground, stones and other debris on the ground can easily interfere with the detection effect of the radar, and may even damage the radar equipment, reducing its service life and detection accuracy. Therefore, there is a need for an improved road hole detection device that can increase the moving speed and remove road obstacles. Utility Model Content

[0005] In view of the existing deficiencies, the utility model provides a road hole detection device, which solves the problems raised by the above background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A road hole detection device comprises a frame, a push handle is fixedly connected to the left side of the frame, walking wheels are installed at the four corners of the frame, a ground penetrating radar is fixedly provided on the lower side of the inner part of the frame, an antenna is installed on the frame on the right side of the push handle, two groups of quick connection mechanisms are symmetrically arranged at the right end of the frame, an obstacle clearing mechanism is arranged at the lower side of the quick connection mechanism, and a spraying mechanism is arranged on the upper side of the frame.

[0008] Furthermore, the quick connection mechanism includes an active sleeve, a right-angle connecting rod, a telescopic rod, an adjusting bolt, a connecting plate and a positioning hole. The active sleeve is mounted on the frame, and a right-angle connecting rod is fixedly connected to the ring surface of the active sleeve.

[0009] Furthermore, a ring groove is provided on the frame at a connection position with the movable ferrule, the movable ferrule is sleeved in the ring groove, and the movable ferrule is rotatably connected to the frame through the ring groove.

[0010] Furthermore, the obstacle clearing mechanism includes a push plate, a back plate, a connecting arm and a fixed sleeve. Two sets of fixing sleeves are fixedly provided at the lower side of the right end of the frame. A connecting arm is fixedly connected to the right side of the fixing sleeve ring surface. The right end of the connecting arm is fixed to the back plate. A push plate is fixedly provided on the right side of the back plate.

[0011] Furthermore, the push plate is configured as a triangular structure with its sharp corner facing outward, the upper end of the push plate is inclined to the left, and the longitudinal width of the push plate is greater than the spacing width between the two sets of walking wheels.

[0012] Furthermore, the spraying mechanism includes a base plate, a storage tank, a suction hose, a spray pump, a feed hose, a nozzle and a fixed plate. The base plate is fixedly arranged on the upper side of the frame, and the storage tank is fixedly arranged on the base plate. A spray pump is installed on the base plate on the right side of the storage tank.

The right end of the feed hose is connected to the nozzle, and the nozzle is assembled at the bottom of the fixed plate, and the fixed plate is fixed between the two sets of connecting arms.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model can be quickly connected to an external two-wheeled electric vehicle through the quick connection mechanism, and a fixed connection between the two is achieved through the quick connection mechanism, and then the cart-type ground penetrating radar is driven to move by the two-wheeled electric vehicle, without the need for manual pushing by the operator, thereby reducing the labor intensity of the operator and increasing the moving speed of the cart-type ground penetrating radar, thereby accelerating the detection speed of the cart-type ground penetrating radar and improving the detection efficiency.

[0015] 2. The obstacle-clearing mechanism provided in the utility model can clear obstacles on the road, such as stones, solid debris, etc., during the process of moving forward, so as to ensure that the ground-penetrating radar can detect smoothly and avoid obstacles from causing damage to the radar equipment. When the frame drives the ground-penetrating radar to move, the push plate will move forward with it. When encountering an obstacle, the push plate will push it away, ensuring that the ground-penetrating radar can continue to detect without obstacles. The back plate and the connecting arm ensure the stability and rigidity of the push plate when pushing away obstacles, and the fixing sleeve ensures that the entire obstacle-clearing mechanism can be firmly mounted on the frame and will not fall off or shift during the obstacle-clearing process.

[0016] 3. The push plate is set to a triangular structure with its sharp corners facing outwards, the upper end of the push plate tilted to the left, and the longitudinal width of the push plate is greater than the spacing width of the two sets of running wheels. The push plate with a triangular structure enhances its structural strength and stability. At the same time, the push plate is designed to be triangular so that obstacles can be pushed to both sides during obstacle removal to prevent obstacles from accumulating in front of the push plate.

[0017] 4. The spraying mechanism can spray the paint onto the road surface and can mark the holes in time when they are detected, so that the subsequent construction personnel can quickly identify and locate the holes. When a hole is detected, the spraying pump is started, and the spraying pump extracts the spraying material from the storage tank through the suction hose, and after pressurization, it is delivered to the nozzle through the delivery hose. The nozzle sprays the spraying material at a certain pressure and speed, thereby forming an obvious mark on the road for subsequent construction processing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] like Figures 1 to 5 As shown, a road hole detection device includes a frame 7, a push handle 1 is fixedly connected to the left side of the frame 7, walking wheels 2 are installed at the four corners of the frame 7, a ground penetrating radar 6 is fixedly provided on the lower side of the frame 7, an antenna 8 is installed on the frame 7 on the right side of the push handle 1, two groups of quick connection mechanisms 4 are symmetrically arranged on the right end of the frame 7, an obstacle removal mechanism 5 is arranged on the lower side of the quick connection mechanism 4, and a spraying mechanism 3 is arranged on the upper side of the frame 7. This design solves the problem that the existing ground penetrating radar 6 is mainly moved by manual pushing, and the manual pushing method is slow, resulting in slow detection speed, affecting the detection efficiency of road holes, and because the transmitter on the ground penetrating radar 6 is close to the ground, stones and other debris on the ground are easy to interfere with the detection effect of the radar, and may even damage the radar equipment, reducing its service life and detection accuracy.

[0027] The quick connection mechanism 41 includes a movable ferrule 41, a right-angle connecting rod 42, a telescopic rod 43, an adjusting bolt 44, a connecting plate 45 and a positioning hole 46. The movable ferrule 41 is sleeved on the frame 7. The right-angle connecting rod 42 is fixedly connected to the ring surface of the movable ferrule 41. The right end of the right-angle connecting rod 42 is fixedly provided with a telescopic rod 43. The right end of the telescopic rod 43 is penetrated by an adjusting bolt 44, and the adjusting bolt 44 is connected to the telescopic rod 43 by screw thread engagement. The end of the adjusting bolt 44 is sleeved with a connecting plate 45, and a positioning hole 46 is opened at the right end of the connecting plate 45. The quick connection mechanism 4 can be quickly connected to the external two-wheeled electric vehicle, and the fixed connection between the two is realized by the quick connection mechanism 4, and then the radar is driven to move by the two-wheeled electric vehicle, without the need for manual pushing by the operator, which reduces the labor intensity of the operator, and increases the moving speed of the cart-type ground penetrating radar 6, thereby accelerating the detection speed of the cart-type ground penetrating radar 6 and improving the detection efficiency. When making the connection, first adjust the length of the telescopic rod 43 so that the positioning hole 46 on the connecting hanging plate 45 is aligned with the rear wheel axle of the two-wheeled electric vehicle, and then adjust the distance between the connecting hanging plate 45 and the rear wheel axle by rotating the adjusting bolt 44 so that the positioning hole 46 can be sleeved on the rear wheel axle, and then tighten the connecting hanging plate 45 with the nut.

[0028] The frame 7 is provided with an annular groove at the connection with the movable ferrule 41, and the movable ferrule 41 is sleeved in the annular groove, and the movable ferrule 41 is rotatably connected to the frame 7 through the annular groove. The design can realize the rotational connection between the movable ferrule 41 and the frame 7 through the provided annular groove, which is convenient for adjusting the angular position of the entire quick connection mechanism 4, so that the quick connection mechanism 4 has a certain flexibility and can adapt to different usage scenarios and needs. At the same time, the annular groove plays a role of limiting the movable ferrule 41, preventing the movable ferrule 41 from moving forward and backward on the frame 7, and can ensure the stability of the connection.

[0029] The obstacle-clearing mechanism 5 includes a push plate 51, a back plate 52, a connecting arm 53 and a fixing sleeve 54.

The push plate 51 is fixedly arranged on the right side of the back plate 52. The obstacle-clearing mechanism 5 can remove obstacles on the road surface, such as stones, solid debris, etc., during the process of moving forward, so as to ensure that the ground-penetrating radar 6 can be detected smoothly, while avoiding obstacles from causing damage to the radar equipment. When the frame 7 drives the ground-penetrating radar 6 to move, the push plate 51 will move forward. When encountering an obstacle, the push plate 51 will push it away, ensuring that the ground-penetrating radar 6 can continue to detect without obstacles. The back plate 52 and the connecting arm 53 ensure the stability and rigidity of the push plate 51 when pushing away the obstacle, and the fixing sleeve 54 ensures that the entire obstacle-clearing mechanism 5 can be firmly mounted on the frame 7 and will not fall off or shift during the obstacle-clearing process.

[0030] The push plate 51 is set to a triangular structure, with its sharp corner facing outward, the upper end of the push plate 51 tilted to the left, and the longitudinal width of the push plate 51 is greater than the spacing width of the two sets of running wheels 2. The push plate 51 with a triangular structure can enhance its structural strength and stability. At the same time, the push plate 51 is designed to be triangular so that obstacles can be pushed to both sides during obstacle removal to prevent obstacles from accumulating in front of the push plate 51.

The bottom plate 31 is fixedly arranged on the upper side of the vehicle frame 7. The material storage tank 32 is fixedly arranged on the bottom plate 31. The spraying pump 34 is installed on the bottom plate 31 on the right side of the material storage tank 32. The input end of the spraying pump 34 is connected to the material storage tank 32 through the suction hose 33. The output end of the spraying pump 34 is connected to the material delivery hose 35.

The spraying mechanism 3 is set up to spray the paint on the road surface, and can mark the cavity in time when it is detected, so that the subsequent construction personnel can quickly identify and locate the cavity position. When a cavity is detected, the spray pump 34 is started, and the spray pump 34 draws the spray material from the storage tank 32 through the suction hose 33, and delivers it to the nozzle 36 through the delivery hose 35 after pressurization. The nozzle 36 sprays the spray material at a certain pressure and speed, thereby forming an obvious mark on the road for subsequent construction processing.
