Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of road maintenance, and in particular relates to a crack repairing device for road maintenance. Background Art
[0002] In the field of road maintenance, crack repair is an important task to ensure road safety and extend road service life. Currently, there are various crack repair devices on the market. They usually include a pipeline system for delivering repair agent. The main working principle of these systems is to deliver the repair agent through the pipeline into the road cracks to fill the cracks and prevent further damage.
[0003] However, existing crack repair devices have certain limitations when treating curved cracks. Since the degree of curvature and direction of cracks may vary, the fixed pipe cannot adapt to the shape of all cracks when the repair vehicle moves. As a result, the repair agent cannot fill the cracks evenly, or cannot reach certain bends, or even gets stuck, thus affecting the repair effect.
[0004] For example, conventional repair devices typically use straight pipes. When encountering a curved crack, the repair agent can only directly contact the straight portion of the crack at the end of the pipe and cannot follow the curved path of the crack. This results in uneven distribution of the repair agent in the crack, making it impossible to form a continuous and uniform repair layer. In extreme cases, if the crack is very curved, the end of the pipe may not even be able to contact certain parts of the crack, resulting in an incomplete repair.
[0005] Therefore, the prior art urgently needs a repair device that can automatically adapt to the degree of crack curvature. Utility Model Content
[0006] The purpose of the utility model is to provide a crack repair device for road maintenance, which can effectively repair cracks of different curvature degrees and directions, improve the repair quality, and extend the service life of the road.

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.
[0023] like Figure 1-4 As shown, a crack repair device for road maintenance includes a repair vehicle 1, a repair agent tank 2 and a liquid pump 3 are installed on the top of the repair vehicle 1, a heating element such as a heating wire and a stirring paddle can be provided inside the repair agent tank 2 for heating and stirring the repair agent that needs to be heated, a sliding groove 5 is further provided inside the repair vehicle 1, a top mounting tube 4 is slidably connected inside the sliding groove 5, a bottom mounting tube 8 is installed at the bottom of the inner side of the top mounting tube 4, a threaded wire 14 is provided at the top of the outer side of the bottom mounting tube 8, a threaded groove 15 is provided on the inner side of the top mounting tube 4 and at a position corresponding to the threaded wire 14, and the threaded wire 14 is threadedly connected to the threaded groove 15, through this arrangement, the threaded wire 14 can be screwed into the top mounting tube 4, thereby adjusting the position of the bottom mounting tube 8 to move up and down, and the adjustment structure can also be achieved by using a driving component such as a push rod motor;
[0024] The repair vehicle 1 is also provided with a storage battery for temporarily supplying power to the electrical components on the repair vehicle 1. The repair vehicle 1 is mainly powered by external wires.
[0025] The input end of the liquid pump 3 is connected to the repair agent tank 2 through a hose, and the output end of the liquid pump 3 is connected to the top of the top installation pipe 4 through a hose;
[0026] When using the device, the bottom installation pipe 8 can be inserted into the position inside the crack in the road. By starting the liquid pump 3, the liquid pump 3 transports the repair agent inside the repair agent tank 2 to the top installation pipe 4 and enters the interior of the bottom installation pipe 8. The liquid is transported into the crack through the bottom installation pipe 8 to repair the crack. A bifurcated flow channel can be provided at the top of the top installation pipe 4 to avoid the position where it cooperates with the subsequent limit column 6.
[0027] A guide assembly is installed in the sliding groove 5, and the guide assembly is used to guide the top mounting tube 4 and the sliding groove 5. A rotating assembly is installed between the top mounting tube 4 and the bottom mounting tube 8.
[0028] Refer to the attached Figure 2 The guide assembly includes a limiting column 6 fixed inside the sliding groove 5, and a first spring 7 is provided on both sides of the top mounting tube 4 and between the repair vehicle 1 and on the outside of the limiting column 6;
[0029] When repairing a crack, the user can push the repair vehicle 1 to move, driving the bottom mounting tube 8 to move. When the crack bends, the crack at the bend can resist the bottom mounting tube 8, and the bottom mounting tube 8 drives the top mounting tube 4 to move in the opposite direction of the bend of the crack, and compresses the first spring 7 at that location, so that the bottom mounting tube 8 can move in the crack and completely repair the crack.
[0030] Refer to the attached Figure 3-4 , a rotating assembly is installed between the top mounting tube 4 and the bottom mounting tube 8, and the rotating assembly includes a plurality of second springs 12 fixed to the bottom of the top mounting tube 4 and located on the outside of the bottom mounting tube 8, and a mounting piece 11 is fixed to the bottom of the second spring 12, and the bottom of the mounting piece 11 is rotatably connected with a rotating body 9, and the rotating body 9 is sleeved on the outside of the bottom mounting tube 8. Through the setting of the rotating body 9, the rotating body 9 is also extended into the crack. Through the direct contact between the rotating body 9 and the external crack, the contact between the bottom mounting tube 8 and the crack can be avoided, thereby protecting the service life of the bottom mounting tube 8. The rotating body 9 can be made of iron or other materials, thereby enhancing its rotation effect and service life. A rotating ring 10 is fixed to the bottom of the rotating body 9, and the rotating ring 10 is also rotatably connected to the bottom mounting tube 8. Through the setting of the rotating ring 10, when encountering a smaller crack, the rotating ring 10 can be inserted into the crack, so that the rotating ring 10 is in contact with the crack;
[0031] Through the setting of the second spring 12, the second spring 12 can drive the rotating body 9 to move downward, always in contact with the crack, and then the entire rotating body 9 is in contact with the crack to ensure the rotation effect. Furthermore, a limiting rod 13 is installed between the mounting plate 11 and the top mounting tube 4 and inside the second spring 12, and the limiting rod 13 is fixedly connected to the mounting plate 11, and the limiting rod 13 slides inside the top mounting tube 4. Through the setting of the limiting rod 13, a stable downward driving force can be provided for the second spring 12 to avoid the second spring 12 from being completely compressed.
[0032] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
