Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] This embodiment provides a long-distance bolt removal and automatic grabbing tool, its structure is as follows figure 1 , figure 2 and image 3 As shown, it is mainly composed of three parts: main body 1, transition sleeve 2 and jacket 3, all of which are processed by stainless steel.

[0035] The main body 1 includes an intermediate body and a connecting body at the end. The intermediate body and the connecting body are two cylindrical structures with different diameters. The diameter of the intermediate body is greater than the diameter of the end; The length is determined according to the actual operation distance on site; the upper end of the connecting body has a round hole, and the main body 1 and the long rod 11 are connected together by the pin 12 .

[0036] The intermediate outer wall of the main body 1 is provide...

Abstract

The invention belongs to the technical field of field maintenance of nuclear power plants, and particularly relates to a remote bolt dismantling and automatic grabbing tool and a using method thereof.The top end of a main body of the tool is provided with a special head for removing a bolt, and a positioning mechanism at an outer wall of the main body is located in a guide sliding groove of a side wall of a transition sleeve; the lower part of the transition sleeve is provided with a connecting rod for connecting an outer sleeve; and a guiding mechanism arranged on the connecting rod is located in a guiding sliding groove of the outer sleeve. A remote bolt disengaging special waste container used in cooperation with the tool is also provided. The container comprises an unlocking groove and a waste collecting main body. When in use, a cam mechanism is pressed down to enable a gripper to be opened; then the special head is rotated for bolt anti-loosening damage and screwing, and after the bolt is completely withdrawn, the cam mechanism is lifted to enable the gripper to automatically grab the bolt; and finally, the bolt is placed in the special waste container. The tool has the beneficial effects that functions of underwater automatic centering, anti-loosening structure dismounting, screwing dismounting and automatic clamping and releasing are achieved, the tool is light and reliable, and is suitable for underwater remote operation.

Description

technical field [0001] The invention belongs to the technical field of on-site maintenance of nuclear power plants, and in particular relates to a long-distance bolt removal and automatic grabbing tool and a use method thereof. Background technique [0002] After the nuclear reactor unit is in operation, the reactor internals and other components are highly radioactive. With the continuous operation of the unit, the reactor internal components and other components under the conditions of high temperature, high pressure, and water impact in the reactor pressure vessel are gradually aging, and the reliability of the equipment is reduced. Relevant parts need to be replaced and repaired. Replacing and repairing relevant parts requires removal of some fastening bolts. All bolts of the internal components of the pile have been treated with anti-loosening treatment. Therefore, when removing relevant bolts, the anti-loosening structure of the bolts must be destroyed first, and then ...
