DETAILED DESCRIPTION

[0054] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0055] like Figures 1 to 8 As shown, an embodiment of the utility model provides a road bridge crack repair device, comprising:

[0056] Electric box 1;

[0057] Base 101, connected to the electrical box 1;

[0058] A spraying part, arranged on the base 101, so that the repairing agent covers the crack surface;

[0059] The telescopic part is arranged at one side of the spraying part and connected to the electrical box 1 to scrape the repair agent at the crack;

[0060] The smearing part is arranged on one side of the telescopic part;

[0061] The driving part is arranged in the electrical box 1 and connected with the applying part to drive the applying part to eliminate the redundant repairing agent at the crack.

[0062] More preferably, two push handles 102 are installed on the back of the electrical box 1, and two universal wheels 103 are installed on the bottom of the electrical box 1 and the base 101 respectively. The user can first pour the repair agent needed to repair the road or bridge into the spraying part, and then hold the two push handles 102 to push the electrical box 1 and the base 101 to move by external force. When the electrical box 1 and the base 101 move to the cracks on the road surface or bridge surface, the spraying part can spray the repair agent into the cracks, and then use the telescopic part to scrape the repair agent sprayed on the road surface or bridge surface, and then use the driving part to drive the coating part to reciprocate left and right to evenly apply the scraped repair agent, which can ensure that the repair agent evenly fills the cracks, and at the same time, the sprayed repair agent can be leveled immediately to eliminate surface unevenness and excess repair agent.

[0063] like Figures 1 to 8 As shown, the spraying part includes:

[0064] A grouting part, disposed on the base 101;

[0065] A spray barrel 202 connected to the grouting part;

[0066] There are multiple spray heads 203 connected to the spray barrel 202.

[0067] In the embodiment of the utility model, the user pours the repair agent required for repairing the crack into the inner side of the grouting part. When the device moves and passes through the cracks on the road surface or bridge deck, the user controls the spray head 203 to open, so that the repair agent temporarily stored in the spray barrel 202 is sprayed onto the cracks on the road surface or bridge deck through the spray head 203, so that the subsequent telescopic part and the coating part can apply the repair agent to the cracks for repair work.

[0068] like Figures 1 to 8 As shown, the grouting unit includes:

[0069] A grouting bucket 2 is fixed on the base 101 to contain the repairing agent required for road repair;

[0070] One end of the square tube 201 is connected to the grouting bucket 2 , and the other end extends to the outside of the base 101 and is connected to the spraying bucket 202 .

[0071] In the embodiment of the utility model, the liquid repair agent in the grouting barrel 2 can be transferred to the spraying barrel 202 through the square tube 201. More preferably, an electromagnetic valve is provided at the connection between the spraying head 203 and the spraying barrel 202 to accurately control the spraying timing of the repair agent.

[0072] like Figures 1 to 8 As shown, the telescopic part includes:

[0073] The telescopic rod 3 is located on one side of the square tube 201, and one end of the telescopic rod is connected to the base 101;

[0074] A spring 301 is sleeved on the telescopic rod 3;

[0075] The triangular plate 302 is connected to the telescopic rod 3 so that the other end of the spring 301 is fixedly connected to the triangular plate 302;

[0076] The rubber rod 303 is connected to the triangular plate 302 to scrape the repair agent sprayed by the spraying part.

[0077] Wherein, the telescopic rod 3 is a freely telescopic rod.

[0078] In the embodiment of the utility model, after the repairing agent for repairing cracks is sprayed on the cracks on the road surface or bridge deck, the user pushes the device to move. At this time, the pressure exerted on the rubber rod 303 in contact with the road surface or bridge deck squeezes the telescopic end of the telescopic rod 3 through the triangular plate 302 and the spring 301 contracts, so that the rubber rod 303 is close to the road surface or bridge deck, and then the rubber rod 303 is close to the road surface or bridge deck to scrape the repairing agent sprayed on the cracks flat, so that the repairing agent fills the cracks.

[0079] like Figures 1 to 8 As shown, the driving unit includes:

[0080] A support portion, disposed in the electrical box 1;

[0081] A movable plate 403 is disposed on the support portion so as to impose longitudinal restrictions on the movable plate 403 through the support portion;

[0082] The rotating plate 402 is rotatably disposed in the moving plate 403 via a bearing, wherein the central axis of the rotating plate 402 coincides with the central axis of the moving plate 403;

[0083] A mounting groove is formed on the rotating plate 402 and deviates from the central axis of the rotating plate 402;

[0084] The eccentric wheel 401 is rotatably disposed in the mounting groove via a bearing;

[0085] The motor 4 is disposed in the electrical box 1 and connected to the eccentric wheel 401 , wherein the connection point between the motor 4 and the eccentric wheel 401 deviates from the central axis of the eccentric wheel 401 .

[0086] In the embodiment of the utility model, since the connection point between the motor 4 and the eccentric wheel 401 deviates from the central axis of the eccentric wheel 401, when the motor 4 is working, the eccentric wheel 401 can be rotated around the connection point, and then the outer periphery of the eccentric wheel 401 is restricted by the installation groove, and the force generated by the rotation of the eccentric wheel 401 around the connection point can be transmitted to the rotating plate 402. Since the installation groove deviates from the central axis of the rotating plate 402, at this time, the rotating plate 402 swings longitudinally in the movable disk 403 with the central axis as the center. Finally, since the support portion imposes longitudinal restrictions on the movable disk 403, the movable disk 403 can reciprocate in the horizontal direction.

[0087] like Figures 1 to 8 As shown, the support portion includes:

[0088] A support plate 405 is disposed in the electrical box 1;

[0089] A support rod 404, one end of which is connected to the movable plate 403, and the other end of which slides through the support plate 405;

[0090] A bent rod 406, connected to one end of the support rod 404 extending outside the support plate 405, and the other end connected to the application part;

[0091] In the embodiment of the utility model, by connecting one end of the support rod 404 to the movable disk 403 and sliding the other end through the support plate 405, a longitudinal limiting force can be applied to the movable disk 403 to prevent the movable disk 403 from being displaced in height, and at the same time, the movable disk 403 can be constrained to move only along the direction of the support rod 404.

[0092] like Figures 1 to 8 As shown, the application part includes:

[0093] A notch is provided on the inner bottom surface of the electrical box 1;

[0094] A cross bar 5 connected to the other end of the curved bar 406;

[0095] A sleeve plate 501, one end of which is sleeved on the cross bar 5, and the other end of which extends to the outside of the electrical box 1 through the notch;

[0096] A circular plate 502 connected to one end of the sleeve plate 501 extending to the outside of the electrical box 1;

[0097] The sponge 503 is disposed on the circular plate 502 .

[0098] In the embodiment of the utility model, through the connection between the cross bar 5 and the bent rod 406, when the movable disk 403 moves along the direction of the support rod 404, the cross bar 5 can be driven to move simultaneously with the movable disk 403, and then the circular plate 502 together with the sponge 503 can be driven to make the same movement as the movable disk 403 under the action of the sleeve plate 501, and the sponge 503 is in contact with the ground. At this time, the repair agent after scraping the cracks on the ground can be further evenly smoothed by the sponge 503.

[0099] In a specific embodiment, the user first needs to open the top opening of the grouting bucket 2, and then place the repair agent required for repairing the cracks in the grouting bucket 2 for storage. When the repair agent is needed to repair the cracks, the user holds the two pushers 102 and pushes the electric box 1 and the base 101 by external force to move the electric box 1 and the base 101 to the cracked part on the road surface or bridge surface. At this time, the spray head 203 is controlled to open, so that the repair agent is sprayed to the cracks on the road surface or bridge surface through the spray head 203;

[0100] Then, the user continues to push the electric box 1 and the base 101 to move. At this time, the pressure on the rubber rod 303 in contact with the road surface or bridge surface squeezes the telescopic end of the telescopic rod 3 through the triangular plate 302 and the spring 301 contracts, so that the rubber rod 303 is closely attached to the road surface or bridge surface. Then, the rubber rod 303 is closely attached to the road surface to flatten the repair agent sprayed on the crack, so that the repair agent fills the crack.

[0101] Subsequently, the user starts the motor 4 so that the output end of the motor 4 drives the eccentric wheel 401 to rotate, and the eccentric wheel 401 rotates with the output end of the motor 4 as the center. At the same time, when the eccentric wheel 401 rotates, it drives the rotating plate 402 through the bearing to generate an extrusion force on the inner side of the movable disk 403. Since the support rods 404 and the support plates 405 arranged on both sides of the outer wall of the movable disk 403 limit the movable disk 403 to move only in the horizontal direction, when the motor 4 drives the eccentric wheel 401, the movable disk 403 can drive the support rods 404, the bent rod 406 and the cross bar 5 to perform horizontal reciprocating motion at the same time under the action of the eccentric wheel 401. Since the sleeve plate 501 is mounted on the outer side of the cross bar 5, the cross bar 5 can drive the sleeve plate 501 to perform horizontal reciprocating motion, and then drive the circular plate 502 together with the sponge 503 to perform horizontal reciprocating motion. The sponge 503 is in contact with the ground. At this time, the repair agent after scraping the cracks on the ground can be further evenly smoothed by the sponge 503.

[0102] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
