Description

Technical Field

[0001] The present invention relates to the technical field of highway maintenance, and particularly to a highway crack repair device. Background Art

[0002] After a highway has been used for a long time, cracks will appear on its surface. Usually, the cracks have irregular shapes and different lengths, ranging from a few centimeters to several meters. During highway maintenance, due to the various shapes of the cracks, larger caulking devices are more limited and inflexible in use, and the position needs to be adjusted at any time, which is inconvenient to use.

[0003] For the above reasons, in many cases, manual caulking work is adopted. When manually caulking, the Laoba road glue liquid is first stored in a glue bottle, and the glue bottle is provided with a glue injection nozzle. The staff holds the glue bottle and keeps a certain distance between the glue injection nozzle and the crack to squeeze the Laoba road glue liquid into the crack. In the whole process, a certain posture needs to be deliberately maintained by humans, which is quite tiring for long-term work. As the working time increases, the work efficiency will also continue to decrease. To improve the repair efficiency of cracks, it is urgent to solve this problem. Summary of the Invention

[0004] To solve the technical problems in the background art, the present invention proposes a highway crack repair device.

[0025] As Figure 1 shown, Figure 1 Schematic diagram of the structure of an implementation manner of a highway crack repair device proposed by the present invention.

[0026] Referring to Figure 1 , a highway crack repair device proposed by the present invention includes:

[0027] A carrier 1, which has support legs 11, and the support legs 11 have rollers 111 for moving the carrier 1;

[0028] A glue cylinder 2, which is assembled on the carrier 1, and the glue cylinder 2 has a glue injection nozzle 21 for discharging the glue inside it;

[0029] A push plate 3, which is installed inside the glue cylinder 2 and is used to extrude the glue inside the glue cylinder 2 so that the glue is discharged from the glue injection nozzle 21;

[0030] An execution component 4, which is installed on the carrier 1, and its output end extends into the glue cylinder 2 and is movably installed on the push plate 3 to drive the push plate 3 to move axially along the glue cylinder 2;

[0031] The execution component 4 can be set in the structure of a traditional glue gun or in the way of worm and worm gear cooperation. There are many implementation manners of the execution component 4, which will not be elaborated here.

[0032] When the device is specifically used, first store the Laoba road glue in the glue cylinder 2, then install the glue cylinder 2 on the carrier 1, so that the glue injection nozzle 21 is kept at a certain distance from the crack, and inject the Laoba road glue into the crack to fill the road surface;

[0033] In this process, the carrier 1 keeps the appropriate distance between the glue injection nozzle 21 and the crack. By controlling the carrier 1 to move along the crack trajectory, the labor intensity of manual work can be greatly reduced, and it can maintain a good working state for a long time, thereby improving the repair efficiency of the crack.

[0034] Due to the irregular shape of the crack, there are significant differences in the width and depth of each section. At deeper or wider positions, more Laobalu glue solution is needed for filling, while at shallower or narrower positions, only a small amount of Laobalu glue solution is required. However, since the discharging speed of the injection nozzle 21 is constant, different residence times are needed at different positions of the crack, resulting in low efficiency of highway repair. To solve this problem, the following further embodiments are proposed.

[0035] Referring to Figure 1 and Figure 3 In a further embodiment, it further includes a driving assembly 5. There is an elastic block 22 inside the glue cylinder 2. The injection nozzle 21 is adaptively inserted into a through hole opened on the elastic block 22. The end of the injection nozzle 21 located inside the glue cylinder 2 is sealed. There is a feed port 211 arranged along its axial direction on the side wall of the injection nozzle 21 near its sealed end.

[0036] The carrier 1 is provided with a sleeve 12 and a fixing ring 13. The glue cylinder 2 is adaptively and movably inserted into the sleeve 12. The injection nozzle 21 is fixedly installed inside the fixing ring 13.

[0037] The driving assembly 5 is installed on the carrier 1 and is used to drive the glue cylinder 2 to move axially close to or away from the fixing ring 13 so that the area of the feed port 311 located inside the glue cylinder 2 increases or decreases.

[0038] In this embodiment, the injection nozzle 21 is fixed on the fixing ring 13, and the glue cylinder 2 is movably inserted into the sleeve 12, enabling the injection nozzle 21 to move on the glue cylinder 2. At the same time, a feed port 211 arranged along its axial direction is provided on the side wall of the injection nozzle 21. When the driving assembly 5 drives the glue cylinder 2 to move, it will change the size of the area of the feed port 211 located inside the glue cylinder 2. When the area of the feed port 211 located inside the glue cylinder 2 increases, the speed of the Laobalu glue solution in the glue cylinder 2 entering the injection nozzle 21 will also increase accordingly, thereby changing its discharging speed, making adaptive adjustments at different positions during crack repair, which can greatly reduce the difference in residence time at different positions during crack repair, and further greatly maintain the moving speed of the carrier 1, thus improving the efficiency of highway repair.

[0039] Referring to Figure 2, preferably, it further includes a rotating shaft 6. The driving assembly 5 specifically includes a rack 51, a first gear 52 and a second gear 53. The vehicle 1 includes a bracket part 14 and a leg part 11. The bracket part 14 has a first connection part 141, and the leg part 11 has a second connection part 112. The first connection part 141 and the second connection part 112 are rotatably connected through the rotating shaft 6. The first gear 52 is coaxially installed on the rotating shaft 6, the second gear 53 is fixedly installed on the leg part 11, the first gear 52 and the second gear 53 are meshed, the rack 51 is installed on the rubber cylinder 2, and the first gear 52 is meshed with the rack 51. When the leg part 11 and the bracket part 14 rotate relative to each other, the first gear 52 rotates relative to the second gear 53 so that the rack 51 moves axially along the sleeve 12.

[0040] In the preferred structure of the driving assembly 5, when the vehicle 1 travels to a position where the crack is deeper or wider, the rubber cylinder 2 is rotated clockwise. At this time, the injection nozzle 21 is closer to the crack, and the filling position of the Lo-Bar glue can be controlled more precisely. When the rubber cylinder 2 is rotated clockwise, the first gear 52 rotates relative to the second gear 53. At this time, driven by the first gear 52, the rack 51 can move in the direction of the injection nozzle 21. At this time, the rubber cylinder 2 approaches the fixing ring 13, and the area of the feed port 211 located inside the rubber cylinder 2 increases, and the discharge speed of the injection nozzle 21 increases;

[0041] When the vehicle 1 travels to a position where the crack is shallower, the rubber cylinder 2 is rotated counterclockwise. At this time, the injection nozzle 21 is farther away from the crack, preventing the injection nozzle 21 from touching the edge of the crack. When the rubber cylinder 2 is rotated counterclockwise, driven by the first gear 52, the rack 51 can move in the direction away from the injection nozzle 21. The rubber cylinder 2 is away from the fixing ring 13, and the area of the feed port 211 located inside the rubber cylinder 2 decreases, and the discharge speed of the injection nozzle 21 relatively decreases;

[0042] This kind of setting can largely meet the operation habits of the staff, and at the same time can meet the filling work of different cracks.

[0043] After the crack repair work is completed, since there is Lo-Bar glue residue inside the injection nozzle 21, the Lo-Bar glue will solidify inside the injection nozzle 21 after a period of time, affecting the secondary use of the device. To solve this problem, the following further embodiments are proposed.

[0044] Refer to Figure 3 and Figure 4 , in a further embodiment, the dimension of the feed port 211 in the axial direction of the rubber cylinder 2 is smaller than the dimension of the elastic block 22. When the rubber cylinder 2 is at a first inclination angle relative to the leg part 11, the feed port 211 is at least partially located inside the rubber cylinder 2. When the rubber cylinder 2 is at a second inclination angle relative to the leg part 11, the feed port 211 is at least partially located outside the rubber cylinder 2.

[0045] In this further embodiment, the size of the feed inlet 211 is set to be smaller than the size of the elastic block 22, so that the feed inlet 211 cannot appear inside and outside the rubber cylinder 2 at the same time. After one operation is completed, the position of the injection nozzle 21 can be adjusted on the rubber cylinder 2, so that at least part of the feed inlet 211 is located outside the rubber cylinder 2. In this state, the area of the feed inlet 211 inside the rubber cylinder 2 is zero, and the Lubal glue liquid inside the rubber cylinder 2 can be sealed and stored. At the same time, at least part of the feed inlet 211 is located outside the rubber cylinder 2, so that the air pressures at both ends of the injection nozzle 21 are the same, and the Lubal glue liquid inside the injection nozzle 21 will flow out under its own gravity, effectively avoiding the situation that the Lubal glue liquid accumulates and solidifies in the injection nozzle 21, causing the injection nozzle 21 to be blocked.

[0046] In the specific structural design, there are multiple feed inlets 211, and the multiple feed inlets 211 are arranged in a circular array on the injection nozzle 21.

[0047] It should be noted that there is at least one convex portion on the outer wall of the rubber cylinder 2, and there is at least one guiding groove arranged along its axial direction on the inner wall of the sleeve 12. The convex portion is adaptively installed in the guiding groove to form a binding between the rubber cylinder 2 and the sleeve 12 in the rotational direction. The guiding groove has an extended dimension adapted to the movement track of the rubber cylinder 2 to prevent misalignment between the rack 51 and the second gear 52 when the rubber cylinder 2 moves axially along the sleeve 12.

[0048] In the specific structural design, the supporting leg 11 is provided with a counterweight block, so that when the supporting leg 11 rotates relative to the support portion 14, the roller 111 is always in contact with the ground. The push plate 3 is provided with a rubber ring, so that the push plate 3 is closely fitted with the inner wall of the rubber cylinder 2;

[0049] Setting the counterweight block can lower the center of gravity of the whole device, and can prevent the over-tight fit between the support portion 14 and the supporting leg 11, and the roller 111 from leaving the ground when the support portion 14 rotates.

[0050] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
