The sliding block can drive the rotation of the first hinge block and the connecting rod. Since the connecting rod is hinged with the second hinge block, the second hinge block and the sliding shaft are driven to rotate. Since the sliding shaft rotates with the slide plate The cam is connected with the sliding member, and the sliding member is limited by the supporting block, so the shell body rotates, driving the threaded rod, the rotating cap, the sliding block, the first hinge block, the second hinge block, the connecting rod, and the sliding shaft to rotate around the axis of the sliding shaft, thereby driving the sliding shaft and the sliding plate to slide back and forth vertically in the two supporting blocks, thereby achieving the beneficial effect of the auxiliary grinding plate pressing and grinding the repaired crack position back and forth. The set threaded rod and sliding block can make the slider slide horizontally in the shell body when the threaded rod is rotated. The set rotating cap can facilitate the operator to rotate the threaded rod. When the slider slides close to the axis of the rotating shaft, the axis of the inclined connecting rod rotates counterclockwise and gradually tends to be vertical, but is not set vertically, thereby also driving the sliding shaft and the sliding plate to slide vertically downward in the two supporting blocks, thereby driving the auxiliary grinding plate to be close to the fitting state with the crack. When the motor is turned on, the auxiliary grinding plate can frequently press and rotate the repaired crack position to improve the efficiency of pressing and grinding.

[0029] The present invention is further described in detail below in conjunction with specific embodiments, which are intended to explain the present invention rather than to limit it.

[0030] like Figure 1 and Figure 2 As shown, a crack repair device for road maintenance disclosed by the present invention comprises a bottom plate 1, a moving device 2 is arranged at the bottom end of the bottom plate 1, a seam repairing device 3 is arranged at one side of the top end of the bottom plate 1, and an auxiliary device 4 is arranged at one side of the seam repairing device 3. By arranging the seam repairing device 3, road cracks can be repaired. By arranging the auxiliary device 4, auxiliary treatments such as grinding and pressing can be performed on the repaired cracks, so that the cracks can be quickly flattened and traffic pressure can be reduced. By arranging the bottom plate 1, the seam repairing device 3 and the auxiliary device 4 can be supported. By arranging the moving device 2, the whole device can be movable. The auxiliary device 4 comprises a vertical A vertically arranged support frame 401 is fixedly connected to the bottom plate 1, and a supporting effect is achieved through the arrangement of the support frame 401. A vertically arranged rotating shaft 402 is inserted through the top of the support frame 401, and the rotating shaft 402 can freely rotate around its axis in the support frame 401. A motor 403 is fixedly connected to the top of the rotating shaft 402, and the motor 403 is fixedly connected to the top of the support frame 401. The axis of the output shaft of the motor 403 is arranged in the vertical direction. The arranged motor 403 can provide driving force for the rotating shaft 402. A shell 404 is fixedly connected to the bottom end of the rotating shaft 402, and an opening is arranged at the bottom of the shell 404, such as Figure 4As shown, a horizontally arranged threaded rod 405 is inserted through the shell 404 and the two are rotatably connected. The threaded rod 405 is placed outside the shell 404 and one end is fixedly connected with a rotating cap 406. The arranged rotating cap 406 can facilitate the operator to rotate the threaded rod 405. The threaded rod 405 is placed in the shell 404 and a slider 407 is sleeved on one side. The two side walls of the slider 407 are slidably connected to the inner wall of the shell 404. The bottom end of the slider 407 is hinged with a first hinge block 408, and the adjacent side of the first hinge block 408 is hinged with an inclined connecting rod 409. The rotation of the motor 403 drives the rotating shaft 402 to rotate in the support frame 401, thereby driving the synchronous rotation of the shell 404 fixedly connected with the rotating shaft 402, so that The slider 407 and the threaded rod 405 in the housing 404 can be driven to rotate synchronously. The slider 407 can drive the first hinge block 408 and the connecting rod 409 to rotate. The bottom end of the connecting rod 409 is hinged with a second hinge block 410. The adjacent side of the second hinge block 410 is hinged with a vertically arranged sliding shaft 411. The axis of the sliding shaft 411 does not coincide with the axis of the output end of the motor 403. The sliding shaft 411 is sleeved with a slide plate 412 and the two are rotatably connected. A through groove 413 is vertically opened on one side of the bottom plate 1 close to the slide plate 412. Support blocks 414 are arranged on both sides of the through groove 413, wherein the length of the support block 414 on the left side is greater than that of the support block 414 on the right side. The slide plate 412 is placed between the two support blocks 414. The slide plate 412 and the support The inner wall of the block 414 is slidably connected, and the bottom end of the sliding shaft 411 is fixedly connected with an auxiliary grinding plate 415. Due to the hinge connection between the connecting rod 409 and the second hinge block 410, the connecting rod 409 drives the second hinge block 410 and the sliding shaft 411 to rotate. Since the sliding shaft 411 is rotatably connected to the slide plate 412 and the slide plate 412 is limited by the support block 414, the shell 404 rotates, driving the threaded rod 405, the rotating cap 406, the slider 407, the first hinge block 408, the second hinge block 410, the connecting rod 409, and the sliding shaft 411 to rotate around the axis of the sliding shaft 411, thereby driving the sliding shaft 411 and the slide plate 412 to slide back and forth vertically in the two support blocks 414, thereby realizing the auxiliary grinding plate 415 has the beneficial effect of reciprocatingly pressing the repaired crack position. The threaded rod 405 and the slider 407 can make the slider 407 slide horizontally in the shell 404 when the threaded rod 405 is rotated. When the slider 407 slides close to the axis of the rotating shaft 402, the axis of the inclined connecting rod 409 rotates counterclockwise and gradually tends to be vertical, but is not vertically set, thereby also driving the sliding shaft 411 and the slide plate 412 to slide vertically downward in the two support blocks 414, thereby driving the auxiliary grinding plate 415 to be close to the fit state with the crack. When the motor 403 is turned on, the auxiliary grinding plate 415 can frequently press and rotate and grind the repaired crack position, thereby improving the efficiency of pressing and grinding.

[0031] like Figure 1 and Figure 3 As shown, the mobile device 2 includes two rear wheels 21, which are rotatably connected to the outer walls of both sides of the base plate 1 respectively, and the outer walls of both sides of the base plate 1 near the auxiliary device 4 are fixedly connected with universal wheels 22 respectively. The rear wheels 21 and universal wheels 22 can provide support and movement, and the universal wheels 22 can also achieve steering effects. The seam repairing device 3 includes a pouring bucket 31, which is fixedly connected to the top of the base plate 1. A guide pipe 32 is inserted through one side of the pouring bucket 31 near the auxiliary device 4, and a pump 33 is inserted on the other side of the guide pipe 32. A vertically arranged pouring pipe 34 is inserted at the bottom end of the pump 33, and the pouring pipe 34 passes through the base plate 1. A nozzle 35 is sleeved at the bottom end of the pouring pipe 34 and the two are fixedly connected. By setting the pouring bucket 31, the asphalt body for repairing the crack can be loaded, and the pump 33 is pumped through the guide pipe 32 to extract the asphalt body in the pouring bucket 31, and then sprayed to the crack area through the nozzle 35.

[0032] like Figure 1 and Figure 2 As shown, an outer wall of the base plate 1 on one side away from the auxiliary device 4 is fixedly connected with an inclined handle 11, and the handle 11 can facilitate the staff to push the repair device. A correction rod 12 is fixedly connected to the top of the base plate 1 on the side close to the auxiliary device 4. By setting the correction rod 12, the asphalt can be poured, pressed and polished on the crack more accurately after pushing the handle 11.

[0033] A crack repair method for highway maintenance includes the following process: when in use, the device is pushed to the area to be repaired by the handle 11, and the asphalt in the pouring bucket 31 is transported to the position of the nozzle 35 through the guide tube 32, the pump 33 and the pouring tube 34 by observing the correction rod 12, and poured into the cracks on the ground through the nozzle 35, and then the rotating cap 406 is rotated to drive the rotation of the threaded rod 405, and the threaded rod 405 drives the slider 407 threadedly connected thereto to move horizontally in the shell 404, when the slider 407 moves to the limit position, the rotating cap 406 is stopped, and the connecting rod 409 is in the maximum tilt state, and then the motor 403 is turned on, the motor 403 rotates, drives the rotating shaft 402 to rotate, the rotating shaft 402 drives the shell 404 to rotate, the shell 404 drives the first hinge block 408 hinged to the slider 407 to rotate, the first hinge block 408 drives the tilted connecting rod 409 to rotate, and the connecting rod 409 drives the rotation of the second hinge block 410, and the second hinge block 410 drives the sliding shaft 411 to rotate along the slide plate 412, and the slide plate 412 slides back and forth vertically along the two support blocks 414, thereby achieving the effect of intermittent grinding and pressing of the asphalt body raised on the cracked ground. When rapid grinding and pressing are required, the rotating cap 406 is rotated in the opposite direction to make the axis of the connecting rod 409 hinged to the slider 407 and the first hinge block 408 close to vertical until the auxiliary grinding plate 415 is close to the ground. The change in the inclination angle of the connecting rod 409 also drives the sliding shaft 411 and the slide plate 412 to slide vertically downward in the two support blocks 414, and finally makes the auxiliary grinding plate 415 close to the ground after the crack is repaired. Then the motor 403 is turned on, and the connecting rod 409 in a slightly tilted state rotates, driving the auxiliary grinding plate 415 to frequently and quickly grind and press the repaired ground, thereby improving efficiency.

[0034] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
