Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.
Referring to fig. 1-3, an automatic spraying defect supplementing device comprises a mounting plate 1, a motor 3 is mounted on the outer surface of the rear end of the mounting plate 1, an output shaft of the motor 3 penetrates through the outer surface of the mounting plate 1 and is connected with an eccentric wheel 2, one end, deviating from the circle center, of the eccentric wheel 2 is connected with a connecting rod 4 used for performing front and rear feeding motion along with the rotation of the eccentric wheel 2, a main spray head 5 used for spraying is mounted at one end, far away from the eccentric wheel 2, of the front end of the connecting rod 4, a motor 6 is mounted at one end, far away from the eccentric wheel 2, of the top end of the connecting rod 4, and an output shaft of the motor 6 penetrates through the surface.
Referring to fig. 1, a limiting column is installed on one side of the outer surface of the front end of the mounting plate 1, which is far away from the eccentric wheel 2, and a sliding groove for sliding the limiting column is formed in the surface of the connecting rod 4 in a penetrating manner.
Referring to fig. 2, a circular connecting ring is welded on the outer surface of an output shaft of the second motor 6, and the auxiliary nozzle 7 is inserted into the inner surface of the connecting ring.
Referring to fig. 1, the eccentric wheel 2 is connected with the connecting rod 4 through a rotating shaft.
Referring to fig. 1, a wire inlet groove for connecting with a power line is formed on the surface of each of the first motor 3 and the second motor 6.
The rear end of the mounting plate 1 is connected with a guniting mechanical arm (not shown in the figure), and is driven by the guniting mechanical arm to carry out movable spraying.
Before the jet grouting machine is used, image recognition and image recognition are carried out on the rock wall on the inner side of the tunnel through a camera, a radar, a gyroscope and the like to obtain the rock wall patterns at different positions in the tunnel, the recognized patterns and the rock wall surface outline are drawn into a three-dimensional model drawing according to the running track actually detected by the gyroscope, meanwhile, one point is randomly selected to establish a space coordinate, then the mounting plate 1 is mounted at the top end of a jet grouting mechanical arm, a conveying pipe on the jet grouting mechanical arm is respectively connected with the rear ends of the main spray head 5 and the auxiliary spray head 7, and mounting and detection are completed.
When the device is used, the first motor 3 drives the eccentric wheel 2 to rotate, the inner connecting rod 4 provided with the main spray head 5 is connected with one end, far away from the center of a circle, of the eccentric wheel 2, so that when the first motor 3 drives the eccentric wheel 2 to rotate, the main spray head 5 moves along with the connecting rod 4, and the limiting column at the front end of the mounting plate 1 is inserted into the sliding groove in the connecting rod 4 to limit the rotating position of the connecting rod 4, so that the connecting rod 4 drives the main spray head 5 to perform front-back feeding motion, then the tunnel rock wall surface is sprayed by the main spray head 5, meanwhile, the second motor 6 drives the connecting ring provided with the auxiliary spray head 7 to rotate, so that the auxiliary spray head 7 sprays concrete slurry to the edge of the spraying position of the main spray head 5 to supplement the spraying of the main spray head 5, secondly, the concrete slurry sprayed by the main spray head 5 and the auxiliary spray head 7 impacts each other, and the spraying force and, therefore, the main spray head 5 is assisted to adjust the spraying position, and when the main spray head 5 cannot be sprayed, the second motor 6 is controlled to drive the auxiliary spray head 7 to rotate, so that dead-angle-free spraying can be performed on the rock wall from different angles during coating, and defects in spraying are avoided.
