Description

Technical Field

[0001] The present invention relates to the technical field of building repair equipment, in particular to an environment-friendly building road surface crack repair equipment and method. Background Art

[0002] During the long-term use of a highway, the surface of the highway will crack due to factors such as climate and pressure. If the cracks are not treated in time, on the one hand, it will cause the driving vehicles to jolt, which will cause discomfort to the driver and is also prone to traffic accidents; most of the existing caulking machines are relatively large in size, and people are not convenient and flexible enough to operate them, making it difficult to accurately repair the crack positions, resulting in a situation where more asphalt is poured onto the surrounding road surface, causing waste of resources. In response to this, the patent with the publication number CN 117071390B discloses a highway crack repair device for traffic engineering. By driving the third gears on both sides to rotate through the first gear, the second gear can also rotate synchronously with the first gear, and the device box always moves in a position parallel to the directions of the second rollers on both sides, which is more conducive to direction control. At the same time, this front-narrow-and-rear-wide body design is also more convenient for the operator to view the crack trend at the front end. However, since the pouring part of the above device is set at the head, the operator's line of sight will be blocked by the box body, which is not conducive to the pouring operation. Moreover, when the device is repairing, it cannot remove the dust at the crack position, which is not conducive to the adhesion at the crack position and results in a reduced repair effect.

The upper end of the stirring shaft 310 is connected to a driving member for driving its rotation. The driving member includes a second gear 202 arranged at the upper end of the stirring shaft 310. One side of the second gear 202 meshes with a first gear 201. The first gear 201 is arranged at the output end of a driving motor 200. The driving motor 200 is arranged at the upper end of the mixing tank 300. The upper end of the floating sleeve 305 is connected to a reciprocating driving member for driving its reciprocating movement up and down. A plurality of stirring rods 308 for stirring are arranged outside the floating sleeve 305. The stirring rods 308 are of U-shaped structure.

In this way, during the rotation of the stirring shaft 310, the scraping inclined plate 306 will push up the material at the bottom of the mixing tank 300 and then cut it through the dividing rods. At the same time, under the action of the reciprocating driving member, the stirring rods 308 outside the floating sleeve 305 will rotate and float up and down, so as to ensure the stirring effect on the material; The second gear 202 meshes with a third gear 204; An induction heating coil 301 is sleeved outside the mixing tank 300.

When the rotating column 304 rotates along with the rotating column 304, under the cooperation of the lifting pin shaft 303 and the rotary groove 309, the rotating column 304 will drive the floating sleeve 305 to reciprocate along the axis of the stirring shaft 310; The rotation limiting member includes a guiding protrusion arranged outside the stirring shaft 310. A guiding chute matching the guiding protrusion is arranged on the inner wall of the floating sleeve 305. The guiding chute and the guiding protrusion match each other, so that the floating sleeve 305 can only slide outside the stirring shaft 310 and cannot rotate relatively; The traveling component includes traveling wheels 102 arranged at three corner positions at the lower end of the base 100.

[0033] Working principle: During actual use, the repair material is added into the mixing tank 300 along the feeding hopper 203, and then the mixing assembly stirs the repair material. The driving member drives the stirring shaft 310 to rotate. During the rotation of the stirring shaft 310, the scraping inclined plate 306 will push up the materials at the bottom of the mixing tank 300, and then the dividing rod cuts them. At the same time, under the action of the reciprocating driving member, the stirring rod 308 on the outer side of the floating sleeve 305 will rotate and move up and down, so as to ensure the stirring effect on the materials. The second gear 202 cooperates with the third gear 204 to drive the cross shaft 205 to rotate. The cross shaft 205 drives the transmission slide bar 208 to rotate through the universal joint 207. The transmission slide bar 208 drives the transmission slide sleeve 210 to rotate. The transmission slide sleeve 210 drives the first transmission wheel 419 to rotate through the universal joint 207. The friction force between the first transmission wheel 419 and the active friction disc 411 will drive the active friction disc 411 to rotate. The active friction disc 411 drives the cleaning shaft 406 to rotate. The cleaning shaft 406 drives the cleaning disc 407 to rotate. The cleaning disc 407 drives the cleaning brush 419 to rotate, so as to clean the ground. The armrest frame 405 can drive the dust removal box 400 to move up and down, so as to adjust the cleaning height of the cleaning brush 419. Since the transmission unit here can extend, there will be no interference problem. Then, the negative pressure unit and the purification unit are used to suck away the dust generated by the cleaning of the first transmission wheel 409, thus protecting the environment. After the cleaning is completed, the repair material in the mixing tank 300 is sent out along the feed pipe 104 through the delivery pump 103. The feed pipe 104 here is arranged close to the operator, which facilitates the operation.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
