[0002] When the road surface has been in use for a long period of time, cracks are prone to appear. The cracks will continue to expand under the impact of passing vehicles, causing local road surface breakage. The road administration department will generally repair the cracks in the early stages of their appearance by injecting heated asphalt repair material into the cracks, bonding both sides of the cracks and filling the cracks to prevent them from continuing to expand and break.

[0003] Existing road crack repair devices generally put the repair material into a hollow cylinder on a cart, then put an injection pipe into the crack, and move the cart by manpower to inject the repair material into the crack for repair.

[0004] However, the cracks on the road are generally irregular and crooked, while the injection tube is fixed. When injecting into these irregular cracks, people need to frequently change the direction of the cart with force. If the force of changing direction is large, the injection tube may run out of the crack, resulting in a waste of repair materials.

[0005] To this end, we proposed a road crack repair device that can fill irregular cracks with repair materials without the need to frequently adjust the position of the cart, thereby saving time and effort. Utility Model Content

[0023] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0024] like Figure 1-4 As shown, the technical solution adopted by the present invention is specifically as follows: a road crack repairing device includes two bottom plates 1, and a fixed plate 2 is provided on the side where the two bottom plates 1 are close to each other. A top plate 3 is provided on the top of the two fixed plates 2, and the two fixed plates 2 and the top plate 3 are U-shaped. The advantage of providing the top plate 3 is that the hollow cylinder 8 can be protected from external impact.

[0025] A slide groove 4 is provided at the bottom of the two fixed plates 2, a moving component is arranged inside the slide groove 4, a slider 5 is arranged on the moving component, an L-shaped rod 6 is arranged on the slider 5, an arc plate 7 is installed at the end of the L-shaped rod 6 away from the slider 5, a hollow cylinder 8 for carrying the repair material is installed on one side of the arc plate 7, a discharge pipe 9 is arranged at the bottom of the hollow cylinder 8, and the discharge pipe 9 is used to be inserted into the crack.

[0026] The hollow cylinder 8 is composed of a cylindrical shell and a conical shell. The cylindrical shell can carry the repair material, and the conical shell can quickly guide the repair material out without clogging.

[0027] Its working principle is to first put the repair material into the hollow cylinder 8, and then insert the discharge pipe 9 into the road crack. At this time, it moves so that the repair material enters the crack. When encountering irregular cracks, such as Figure 4 As shown, when moving forward, the discharge pipe 9 first contacts the inner wall of the gap for extrusion, and then the discharge pipe 9 drives the hollow cylinder 8 to drive the L-shaped rod 6 to drive the slider 5 to move the moving assembly inside the slide 4, so that the discharge pipe 9 is always in the crack, and there is no need to adjust or frequently move the position of the cart to fill the repair material in the crack. The device can fill irregular cracks with repair materials without frequently adjusting the position of the cart, achieving the effect of saving time and effort.

[0028] Among them, in order to prevent the discharge pipe 9 from being damaged when it contacts and squeezes the inner wall of the crack, a wear-resistant layer is arranged on the outside of the discharge pipe 9. The material of the wear-resistant layer is polyurethane wear-resistant. The polyurethane wear-resistant layer refers to a coating made of polyurethane and its derivatives with high strength, high toughness, wear resistance and corrosion resistance. The wear-resistant layer can prevent the discharge pipe 9 from being damaged during extrusion.

[0029] At the same time, a feed pipe is arranged on the top of the hollow cylinder 8, and a sealing cover is arranged on the feed pipe. The repair material enters the hollow cylinder 8 for support through the feed pipe. The sealing cover can prevent dust and impurities from entering the hollow cylinder 8 and causing damage to the repair material.

[0030] like Figure 2 As shown, the moving assembly includes a fixed shaft 10 arranged inside the slide groove 4, a slider 5 and a spring 11 are sleeved on the fixed shaft 10, springs 11 are arranged on both sides of the slider 5, and an L-shaped rod 6 is arranged on the slider 5.

[0031] When the discharge pipe 9 first contacts the inner wall of the gap for extrusion, an extrusion force is generated. The extrusion force drives the L-shaped rod 6 to move the slider 5 on the fixed shaft 10 to squeeze the spring 11, so that the hollow cylinder 8 drives the discharge pipe 9 to move, so that the discharge pipe 9 is always in the crack for injection.

[0032] The function of the spring 11 is to restore the original position after the crack is repaired, and to quickly respond to the irregular cracks to move the hollow tube 8.

[0033] The slider 5 matches the slide groove 4. The advantage of such arrangement is that the slider 5 can move smoothly inside the slide groove 4 without getting stuck.

[0034] like Figure 2 As shown, a motor 12 is arranged on the top of the fixed plate 2, a rotating rod 13 is installed on the output end of the motor 12, the bottom of the rotating rod 13 passes through the fixed plate 2 and the hollow cylinder 8, and a stirring rod 14 is arranged on the penetrating part of the rotating rod 13. The rotating rod 13 is driven by the motor 12 so that the stirring rod 14 stirs the repair material to prevent solidification and clogging.

[0035] Wherein, every two stirring rods 14 are arranged alternately with each other, and the advantage of such arrangement is that the stirring effect can be improved.

[0036] like Figure 1 As shown, movable pulleys are provided at the bottom of the two bottom plates 1, and the movable pulleys are used to achieve the effect of facilitating movement.

[0037] Among them, a pushing armrest is arranged on one of the base plates 1, and the whole device can be moved by pushing the armrest.

[0038] The working principle of the utility model is as follows: firstly, the repair material is placed in the hollow cylinder 8, and then the discharge pipe 9 is inserted into the road crack, and at this time, the repair material is moved so that the repair material enters the crack. When an irregular crack is encountered, Figure 4As shown, when moving forward, the discharge pipe 9 first contacts the inner wall of the gap for extrusion, and then the discharge pipe 9 drives the hollow cylinder 8 to make the L-shaped rod 6 drive the slider 5 to move on the fixed shaft 10, so that the discharge pipe 9 is always in the crack, and there is no need to adjust or frequently move the position of the cart to fill the repair material in the crack. The device can fill irregular cracks with repair materials without frequently adjusting the position of the cart, achieving the effect of saving time and effort.

[0039] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
