Embodiment Construction

[0030] The following will be further described in detail through specific embodiments.

[0031] For ease of understanding, a brief introduction to the pneumatic jaw actuator is given first. Pneumatic claw actuators are the components with the highest safety requirements for positioning robots, and because domestic evaporator models include M310, AP1000, Hualong No. 1 and many other models, a pneumatic claw actuator based on a conversion mechanism is particularly important. In this way, the model replacement can be completed quickly through the quick replacement of the conversion mechanism, which can greatly expand the application range of the positioning robot, reduce maintenance costs, shorten maintenance time, and reduce the radiation dose received by equipment personnel due to equipment maintenance.

[0032] Such as figure 1 As shown, the present invention provides a pneumatic claw actuator 1 , including a cylinder 2 and a claw head 3 . Cylinder 2 is made up of two layers...

Abstract

The invention provides a pneumatic clamping jaw actuating mechanism based on a switching mechanism, which comprises an air cylinder and a clamping jaw head, the air cylinder comprises an outer layer cylinder and an inner layer cylinder, the inner layer cylinder can move in the outer layer cylinder, the clamping jaw head is detachably connected to the inner layer cylinder, and the inner layer cylinder drives the clamping jaw head to act. According to the pneumatic clamping jaw executing mechanism based on the switching mechanism, a positioning robot can achieve the clamping function on a heat transfer pipe of a steam generator, the application range of the positioning robot is expanded, the maintenance cost is reduced, the maintenance time is shortened, and the irradiation dose borne by equipment personnel due to equipment maintenance is reduced.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing of steam generators, in particular to a pneumatic jaw actuator based on a conversion mechanism. Background technique [0002] Nuclear power plants have a wide variety of heat exchangers and pressure-bearing equipment, which must be non-destructively tested in accordance with certain specifications before they are put into operation and after they are put into operation. Due to the characteristics of the nuclear industry, these devices either operate under radioactive conditions, or are subject to high temperature and high pressure (tension) and fluctuate frequently, so their inspection cycles are more frequent than other industries. At the same time, in order to avoid the consequences of radioactive leakage, its inspection technology, inspection specifications and other related requirements are also more stringent. The heat transfer tubes of steam generators in nuclear power plant...
