Description
Technical Field
[0001] This utility model relates to the field of adhesive application device technology, and in particular to an adhesive application device for a pipe burst repair robot. Background Technology
[0002] In industrial production and urban infrastructure, various pipelines are widely used to transport water, oil, and gas. Due to long-term service, pipelines are susceptible to corrosion, external damage, and aging, leading to frequent pipe bursts. Traditional pipeline repair methods typically require manual operation. In confined and harsh pipeline environments, manual adhesive application is difficult, inefficient, and of questionable quality, while also posing safety risks. With the continuous advancement of robotics technology, its application in various fields is becoming increasingly widespread. Robots offer advantages such as high automation, high precision, and adaptability to harsh environments. Applying robotics technology to pipeline burst repair has become an effective way to solve the aforementioned problems. As a key component of pipeline burst repair robots, the performance of the adhesive application device directly affects the quality and efficiency of pipeline repair. To improve the quality and efficiency of pipeline repair and reduce repair costs and safety risks, the industry has placed higher demands on pipeline burst repair robots and their adhesive application devices. These devices must be able to adapt to different types and specifications of pipelines, achieve precise, efficient, and uniform adhesive application, and possess good reliability and stability.
[0003] A search revealed Chinese Patent Publication No. CN208712081U, which discloses a high-efficiency robotic adhesive application device, comprising a base plate and a frame. The base plate is located at the bottom of the frame, and the top of the base plate is fixedly connected to the robot body via a mounting bracket. This utility model utilizes a glue-applying box, lifting structure, tray, industrial control computer bracket, industrial control computer body, camera, fixing plate, limit slider, glue-applying cylinder, push plate, lateral movement cylinder, glue-applying mechanism, cleaning mechanism, glue storage box, glue-applying valve, light source, and camera device to create a highly efficient robotic glue-applying device. This device solves the problem of reduced efficiency caused by separate installation of glue-applying and camera inspection in existing robotic glue-applying devices. It boasts the advantage of high-efficiency glue application, allowing simultaneous glue application and inspection at the same workstation. This simplifies the glue-applying and inspection structure, significantly reduces the space occupied at the workstation, shortens the production cycle, and lowers equipment costs, greatly improving glue-applying efficiency. However, if the glue is not accurately applied to the damaged area of the pipe, an effective sealing layer cannot be formed. In water pipe burst repair, deviations in the glue application position can cause water to continue to leak from the damaged area, failing to achieve the repair purpose and affecting the normal use of the pipe.

[0045] Please see the appendix Figure 3 - Appendix Figure 6 The bottom of the fixed plate 1 is fixedly connected to the four sides of the fixed plate 25, and the bottom of the fixed plate 25 is fixedly connected to the rollers 26.

[0049] Working principle: The servo motor 14 drives the rotation of the large gear 15. The rotation of the large gear 15 moves the meshing toothed strip 16 to the left, which can precisely control the position of the sprayer 7, so that it accurately reaches the glue application area of the pipe, ensuring the accuracy of the glue application position and avoiding glue application deviation and omission. At the same time, the small motor 11 drives the rotation of the small gear 12, which in turn drives the rotation of the meshing half gear 9, thereby realizing the brushing effect of the sprayer 7. The rotation of the half gear 9 can make the sprayer 7 oscillate at a specific angle and frequency, simulating the action of manual brushing, so that the glue can be applied more evenly to the pipe surface, improving the coverage and adhesion of the glue. After one side of the pipe is finished, the device can be moved to the other side of the pipe to achieve the coating effect around the perimeter of the pipe. At the same time, the paint can be replenished through the coating tube 8, which helps to maintain continuous glue application and avoid glue application interruption and uneven glue layer thickness due to insufficient paint, thus improving work efficiency and the stability of glue application quality.
[0050] Before maintenance, the cleaning position is adjusted using the telescopic rod 201 to reach a suitable height. Then, the servo motor 203 drives the reciprocating screw 204 to rotate. The rotation of the reciprocating screw 204 moves the cleaning brush 205 back and forth, thereby achieving the cleaning effect on the pipe. Driven by the reciprocating screw 204, the cleaning brush 205 moves back and forth rhythmically, which can repeatedly clean the pipe surface. It can effectively remove dirt, debris and old adhesive from the pipe surface, providing a clean surface for subsequent adhesive application and maintenance work. This helps to improve the adhesion between the adhesive and the pipe and ensure the quality of maintenance.
