Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the polishing device for the inner wall of the pressure pipeline comprises actuating mechanisms 1 arranged at two ends, wherein the actuating mechanisms 1 at the two ends are connected through a driving mechanism 3.
As shown in fig. 3 and 4, the specific structure of the actuator 1 is a regular polygon link structure formed by hinging a plurality of links 101, in the specific embodiment, the link structure is a regular hexagon star-shaped regular polygon link structure formed by hinging twelve links 101, the hinge joints at the outer sides of the links 101 are rotatably provided with the polishing wheels 106, and the regular polygon link structure can perform telescopic motion, so that all the polishing wheels 106 perform equidistant position change, and thus the outer circumferences of all the polishing wheels 106 can be tangent to circles with different diameters, that is, all the polishing wheels 106 can be pressed on the inner wall of a pressure pipeline at the same time, and can adapt to pressure pipelines with different pipe diameters.
The articulated department in the outside of connecting rod 101 still rotates screw axis 2 that is provided with rubber material, and helical screw thread has been seted up to the periphery of screw axis 2, and when screw axis 2 rotated, can drive this device wholly and can also carry out axial translation when carrying out the circumferential rotation in pressure conduit, this device wholly realizes screw motion promptly in pressure conduit. The rubber material has certain elasticity and large friction force with the inner pipe wall, so that the reliable rolling of the screw shaft 2 on the inner pipe wall can be ensured, and two ends of the screw shaft 2 are respectively and rotatably connected with the outer hinged parts of the connecting rods 101 of the actuating mechanisms 1 at two ends. In order to balance the stress and make the device operate more smoothly, the screw shaft 2 and the polishing wheel 106 are arranged at intervals, in the specific embodiment, three screw shafts 2 and three polishing wheels 106 are arranged, and the screw shaft 2 and the polishing wheel 106 are arranged at intervals to just occupy six external hinges of the regular polygon connecting rod structure in the shape of a regular hexagon star.
In specific implementation, the outer circumference of the screw shaft 2 is slightly larger than the outer circumference of the polishing wheel 106, so that when the regular polygonal connecting rod structure is extended, when the polishing wheel 106 is slightly contacted with the inner pipe wall, the screw shaft 2 is tightly pressed against the inner pipe wall, and when polishing, the friction force between the polishing wheel 106 and the inner pipe wall is far smaller than the friction force between the screw shaft 2 and the inner pipe wall, so that when polishing is performed, the screw shaft 2 rotates to drive the whole device to perform stable and reliable screw motion in the pressure pipeline.
In order to drive each screw shaft 2 and the polishing wheel 106 to rotate, a motor can be independently arranged on each screw shaft 2 and each polishing wheel 106, and the rotation speed synchronization between the motors is also required to be ensured. The application adopts a specific mode that a first rotating wheel 102 and a third rotating wheel 107 are rotatably arranged at the hinged position of the outer side of a connecting rod 101, the first rotating wheel 102 and the third rotating wheel 107 are arranged at intervals, a spiral shaft 2 is arranged on the first rotating wheel 102, and a polishing wheel 106 is arranged on the third rotating wheel 107, namely, the spiral shaft 2 and the polishing wheel 106 are also arranged at intervals. A second rotating wheel 103 is rotatably arranged at the inner side hinge joint of the connecting rod 101; the second rotating wheel 103 and the adjacent first rotating wheel 102 are driven by a driving belt 104, and the second rotating wheel 103 and the adjacent third rotating wheel 107 are driven by the driving belt 104, so that all the first rotating wheel 102, the second rotating wheel 103 and the third rotating wheel 107 are connected by the driving belt 104 to form a whole capable of synchronously rotating together. Each first rotating wheel 102 is provided with an actuating motor 105 arranged on the connecting rod 101 for driving, the rotation of the first rotating wheel 102 can drive all the first rotating wheel 102, the second rotating wheel 103 and the third rotating wheel 107 to synchronously rotate, the motive power for rotation is the resultant force of all the actuating motors 105, and the actuating motors 105 with a plurality of smaller powers can jointly drive the screw shaft 2 to realize rotation with larger torque and drive the polishing wheel 106 to realize rotation with larger rotating speed, so that the device can move more stably in a pipeline, and the polishing effect on the inner wall of the pipeline is better. Compared with the method that the motor is separately arranged on each screw shaft 2 and each polishing wheel 106, the synchronous rotation of all the screw shafts 2 and the synchronous rotation of all the polishing wheels 106 at the same speed can be realized more conveniently, and the number of the motors is saved. The rotation speeds of the screw shaft 2 and the polishing wheel 106 can be adjusted by exchanging the first and third pulleys 102 and 107 of different sizes, respectively.
As shown in fig. 5 and 6, in order to drive the regular polygon link structure to extend and contract while maintaining the shape of the regular polygon, and to achieve a larger extension and contraction stroke while saving space, the apparatus further includes a driving mechanism 3 for driving the regular polygon link structure to extend and contract.

The output shafts 305 at both ends of the drive motor 306 are threaded in opposite directions and at the same pitch, thereby enabling the threaded sleeves 304 at both ends to perform synchronous mirror-image motion.
The main frame 301 is provided with a guide groove 307, a supporting shaft 302 which can slide along the guide groove 307 penetrates through the guide groove 307, the guide groove 307 can prevent the supporting shaft 302 from moving in the circumferential direction relative to the driving motor 306, and the outer end of the supporting shaft 302 is rotatably connected with the second rotating wheel 103. The threaded sleeve 304 is connected with the support shaft 302 through a support rod 303, two ends of the support rod 303 are hinged with the threaded sleeve 304 and the support shaft 302 respectively, and the support rods 303 at the two ends are arranged in a splayed shape.
