After the preliminary sealing is finished, a constructor starts the servo motor 103, the servo motor 103 starts to drive the threaded rod 104 to rotate, the threaded rod 104 drives the upper sliding frame 105 and the lower sliding frame 105 to move towards the middle through two threaded parts on the threaded rod, meanwhile, the upper sliding frame 105 and the lower sliding frame 105 slide along the fixed rod 1041, the upper sliding frame 105 and the lower sliding frame 105 respectively drive the supporting plate 106 on the upper sliding frame and the lower sliding frame to move relatively, the supporting plate 106 drives the adjacent press rollers 108 to move towards the middle through the adjacent two first elastic pieces 107, in the process of moving the two press rollers 108 towards the middle, when the two press rollers 108 contact the hose 109, the two press rollers 108 continue to move towards the middle, meanwhile, the adjacent first elastic pieces 107 on the two press rollers 108 compress to deform, when the upper and lower four first elastic pieces 107 are in a half-compression state, the constructor closes the servo motor 103 at the moment, secondary sealing of the hose 109 is finished, the hose 109 is clamped through the first sliding rod 202, the second sliding rod 204 and the two press rollers 108 clamp the hose 109, tightness in the inflation process is guaranteed, and the condition that the hose 109 cannot be completely inflated is avoided, and the inner wall of the hose 109 cannot be completely inflated is completely due to the fact that the two press rollers 108 can not guarantee sealing the hose 109 is inflated, and the hose 109 is completely inflated.
After the hose 109 is clamped twice, as a distance exists between the two press rollers 108 and the first sliding rod 202 and the second sliding rod 204, the two press rollers 108 and the first sliding rod 202 and the second sliding rod 204 divide the hose 109 into three parts, wherein the end part of the left part is fixedly connected with the pipe to be repaired, the end part of the right part is an opening, the middle part is extruded by the two press rollers 108 and the first sliding rod 202 and the second sliding rod 204 to form a cavity, after the hose 109 is clamped, impurities on the hose 109 can possibly adhere to the inside or the outside of the hose 109, the impurities on the hose 109 can play a supporting role on the two press rollers 108, so that the two press rollers 108 cannot clamp the hose 109, and further the sealing of the two press rollers 108 on the hose 109 cannot be ensured, therefore, a constructor needs to detect whether the hose 109 is clamped and sealed or not firstly, and the following specific operations are performed:
the constructor opens the air pump 302, and the air pump 302 pumps air into the left part of the hose 109 through the air duct 303, and two situations, namely: when the two compression rollers 108 completely seal the hose 109, the gas at the left part of the hose 109 cannot enter the "cavity" in the middle of the hose 109, and the middle "cavity" and the right part of the hose 109 remain the same and cannot expand, and two: when the two press rolls 108 do not completely seal the hose 109, a gap exists between the positions of the hose 109 pressed by the two press rolls 108, and thus, the gas entering the left part of the hose 109 enters the "cavity" in the middle of the hose 109 through the gap between the hoses 109, and the "cavity" in the middle of the hose 109 expands after being inflated with the gas.
After the middle part of the hose 109 is inflated, the hose 109 is inflated continuously along with the continuous inflation of the air, when the inflated hose 109 contacts the trigger switch 301, the hose 109 is inflated continuously and presses the trigger switch 301, when the inflated hose 109 is opened, the trigger switch 301 controls the servo motor 103 and opens the servo motor 103, at the moment, the constructor closes the air pump 302, the servo motor 103 is opened and drives the adjacent press rollers 108 to move towards the middle through the parts of the threaded rod 104, the two sliding frames 105, the two support plates 106 and the like, the two press rollers 108 further clamp the hose 109, then due to the supporting effect of impurities on the hose 109 on the two press rollers 108, the two press rolls 108 cannot move continuously to the middle, in the process, the servo motor 103 continues to work and drives the two slide frames 105 to move continuously to the middle, at this time, the first elastic pieces 107 distributed up and down continue to compress, in the process of moving the two slide frames 105 relatively, the two slide frames 105 drive the straight racks 401 on the two slide frames respectively to move downwards, in the process of moving the straight racks 401 distributed up and down relatively, when the straight racks 401 are meshed with the adjacent straight racks 402, the straight racks 401 drive the adjacent straight racks 402 to rotate along with the movement of the straight racks 401, the two straight racks 402 distributed in front and back mirror images drive the adjacent press rolls 108 to rotate, and the rotating directions of the two press rolls 108 are opposite.
In the process of rotating the upper press roller 108 and the lower press roller 108, as the surfaces of the two press rollers 108 are made of rubber, friction is generated between the press roller 108 and the surface of the hose 109, so that the two press rollers 108 and the hose 109 can move relatively, meanwhile, as the left part of the hose 109 is in a fixed state, the two press rollers 108 move leftwards along the hose 109 in the rotating process, in the leftwards moving process of the two press rollers 108, the two press rollers 108 drive the two rotating frames 102 to deflect through the two supporting plates 106, the two sliding frames 105 and the threaded rods 104, in the deflecting process of the two rotating frames 102, the rotating frames 102 drive the adjacent sliding blocks 403 to deflect synchronously, the sliding blocks 403 slide along the adjacent arc grooves 1011 and squeeze the adjacent second elastic pieces 404, and the second elastic pieces 404 compress.
When all the first elastic pieces 107 are in a fully compressed state, the constructor closes the servo motor 103, the servo motor 103 stops working, the straight rack 401 does not move relatively any more, the straight rack 401 does not drive the straight gear 402 to rotate any more, the two press rolls 108 do not rotate any more, meanwhile, the two press rolls 108 do not move leftwards any more, the contact positions of the two press rolls 108 and the hose 109 are changed by moving the two press rolls 108 leftwards, the contact between the two press rolls 108 and the part, where the hose 109 is attached with impurities, of the two press rolls 108 is lost, and the situation that the hose 109 cannot be clamped by the two press rolls 108 due to the fact that impurities are attached to the part, which is originally clamped by the two press rolls 108, of the hose 109 is avoided.
In the process of deflection of the two rotating frames 102, the two rotating frames 102 rotate by taking the joint of the two rotating frames 102 and the shell 101 as the center of a circle, in the process of rotation of the two rotating frames 102, the two rotating frames 102 drive the two press rolls 108 to synchronously rotate, in the process, the motion trail of the two press rolls 108 moves leftwards and downwards, therefore, the two press rolls 108 drive the hose 109 to deflect downwards, the hose 109 is in a tight state, in the process of deflection of the hose 109 downwards, the contact mode of the hose 109 and the two press rolls 108 is changed from a line to a surface, the contact area of the two press rolls 108 and the hose 109 is further increased, the clamping sealing degree of the two press rolls 108 on the hose 109 is further improved, after the clamping sealing operation of the hose 109 is completed, a constructor starts maintenance work on a pipeline, after the maintenance of the pipeline is completed, when the clamping part of the hose 109 needs to be loosened, a constructor starts the servo motor 103 and the first push rod 207, the servo motor 103 works reversely and drives the two sliding frames 105 to move back, all the first elastic pieces 107 restore to the original position, then the sliding frames 105 drive the adjacent pressing rollers 108 to move back through the first elastic pieces 107 on the sliding frames and lose contact with the hose 109, then the two rotating frames 102 restore under the action of the adjacent second elastic pieces 404, after the two pressing rollers 108 restore to the original position, in the process, the first push rod 207 drives the first sliding rod 202 and the second sliding rod 204 to restore to the original position through the two limiting frames 206, then the constructor closes all the electric elements, and all the parts restore to the original position at the same time, and the use of the device is ended.
