Specifically, when the moving frame 3 drives the flange to move to a position close to the valve body, the electromagnetic ring 8 is started to generate magnetic repulsion to push the follow-up magnetic ring 10 to move, so that the flange is pushed to move to be further close to the surface of the valve body (because the diameter of the follow-up magnetic ring 10 is larger than the diameter of the through hole on the surface of the flange) until the flange is attached to the connecting port on the surface of the valve body.
Embodiment 2:
Fig. 9-11 show that the middle part of the surface of the hanging rod 66 is provided with a connecting rod 12 which is vertically arranged, the tail end of the connecting rod 12 is connected with a circular ring 13, the outer side of the guide rope 63 is provided with a limiting pipe 14, and the top end of the limiting pipe 14 is connected with a limiting ring 11 with the diameter larger than that of the circular ring 13.
The sum of the weight values of the suspension rod 66, the two clamping arms 62, the restraining spring 65 and the electromagnetic plate 64 is smaller than the weight value of the weight round rod 7.
The surface of the guide rope 63 is fixedly sleeved with a constraint ball 16, the top of the surface of the pulley 61 is fixedly provided with an interception rod 15, and the vertical clearance value between the interception rod 15 and the surface of the pulley 61 is smaller than the diameter of the constraint ball 16 but larger than the diameter of the guide rope 63.
Specifically, the length of the limiting tube 14 is equal to the vertical gap between the limiting ring 11 and the counterweight circular rod 7, so that the limiting ring 11 moves upwards synchronously when the counterweight circular rod 7 is lifted up, is not interfered, but is influenced by the limiting ring 11 when the counterweight circular rod 7 falls down, and the tail end of the limiting tube 14 can fall to a state of being attached to the surface of the counterweight circular rod 7;
The movement direction of the guide rope 63 is limited under the influence of the limiting pipe 14, so that the balance weight round rod 7 is kept not to horizontally deviate in the vertical direction, further, the balance weight round rod 7 is prevented from shaking and deviating from a valve body surface connecting port, and the balance weight round rod 7 cannot be effectively lifted when a subsequent flange is close;
Because the gravity of the counterweight round bar 7 acts, after the flange and the connecting port on one side are bolted and fixed, the electromagnetic sheet 64 is closed, so that the two clamping arms 62 are opened, the rotating seat 4 is utilized to drive the valve body to rotate, the working face is switched, at the moment, the counterweight round bar 7 loses the bearing effect of the flange after lifting, falls down and drives the clamping arm 62 on the other side to lift to the original position, but due to the clamping effect of the constraint ball 16 (the distance between the constraint ball 16 and the interception rod 15 is equal to the movable distance of the hanging rod 66, effective interception constraint can be achieved during resetting), the lifting height of the guide rope 63 at one end of the clamping arm 62 is limited, and then the guide rope is matched with the limiting ring 11, so that the counterweight round bar 7 can be autonomously restored to the original state (namely, less than half of the height coincides with the position of the connecting port on the surface of the valve body, and is extruded and lifted when waiting for the flange to approach), and the clamping constraint of the next round is waited.
The present application is not limited to the above-described embodiments, which are adopted in connection with the actual demands, and various changes made by the person skilled in the art without departing from the spirit of the present application are still within the scope of the present application.
