Embodiment 1

[0029] A stripping device for ground decontamination of nuclear facilities, such as figure 1 As shown, it includes a frame 1, a cutting mechanism for cutting the ground, a driving mechanism for driving the cutting mechanism to cut, and a cutterhead feeding mechanism for adjusting the cutting depth of the cutting mechanism.

[0030] Wherein, cutting mechanism is installed on the frame 1 by bearing block 105, and driving mechanism is installed on the frame 1 by supporting frame 102, is connected by coupling 103 between cutting mechanism and driving mechanism.

[0031] Described knife head feeding mechanism comprises the spring seat 202 that is arranged on the frame 1, the spring 211 that is installed on the spring seat 202, is arranged on the adjustment frame on the spring 211, is arranged on the spring seat 202 and is used for controlling the adjustment frame vertically. Height adjustment assembly for vertical height.

[0032] In the present invention, the adjustment frame can...

Embodiment 2

[0041] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the height adjustment assembly on the basis of Embodiment 1, such as image 3 As shown, the specific settings are as follows:

[0042] The spring seat 202, the spring 211, the adjustment frame and the pull rod 204 are two groups, which are respectively arranged on the opposite sides of the cutting mechanism. Two pull rods 204 are hinged at the top, and the middle part of the connecting rod 205 is connected with the end of the steel wire rope 207. And, two springs 211 are arranged in each spring seat 202, four springs 211 are arranged in total, and two sides of cutting mechanism are arranged respectively, as image 3 shown. Through the setting of the above structure, the stability of height adjustment can be further improved.

[0043] At the same time, a guide shaft 208 is provided below the adjustment frame, and a position-limiting sleeve 209 that urges ...

Embodiment 3

[0045] The difference between this embodiment and Embodiment 1 and Embodiment 2 is that this embodiment further provides the structure of the driving mechanism and the cutting mechanism, such as figure 2 and image 3 As shown, the specific settings are as follows:

[0046] The driving mechanism is a motor 101, and the speed is regulated by a control system frequency converter.

[0047] Described cutting mechanism comprises the main shaft 104 that the top is connected on the coupling 103, is fixed on the flywheel disc 106 of main shaft 104 bottom by bolt 108, is fixed on the cutterhead 107 on the flywheel disc 106 by set screw 109; Connected on the frame 1 through the bearing seat 105.

[0048] In this embodiment, the cutting mechanism adopts the principle of flywheel operation, and the flywheel disc 106 adopts a butterfly structure, so that after the cutter disc 107 runs at high speed under the drive of the motor 101, it can use its own inertia to perform rotary cutting ope...

Abstract

The invention discloses a stripping device used for ground dirt removal of a nuclear facility. The problems that in the prior art, the dirt removal efficiency of a mechanical stripping dirt removal method is low, and the dirt removal depth cannot be controlled are solved. The stripping device comprises a rack, a cutting mechanism mounted on the rack through a bearing pedestal, a drive mechanism mounted on the rack through a supporting frame and used for driving the cutting mechanism to achieve cutting and a cutter disc feed mechanism mounted on the rack and used for adjusting the height of thecutting mechanism. The cutting mechanism is connected with the drive mechanism through a coupling. The cutter disc feed mechanism comprises spring seats arranged on the rack, springs mounted on the spring seats, adjusting frames arranged on the springs and a height adjusting assembly arranged on the spring seat and used for controlling the vertical height of the adjusting frame. The adjusting frame is fixedly connected with the cutting mechanism. The stripping device has the advantages that the stripping depth of ground dirt removal can be adjusted and controlled, the dirt removal work face is large, and the dirt removal efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of decommissioning of nuclear facilities, in particular to a stripping device for decontaminating the ground of nuclear facilities. Background technique [0002] In the decommissioning practice of nuclear facilities, decontamination of building structure surfaces is an important task. There are many decontamination techniques for the surface of building structures (mainly concrete), such as mechanical methods such as rough cutting, scraping, grinding, sandblasting, and explosion methods, and new technologies such as lasers and microwaves. Among them, the mechanical stripping and decontamination method is a dry decontamination technology that removes and collects the contaminated surface layer with the help of a special stripping device, and realizes the complete separation of surface pollution and internal clean walls, without causing pollution to spread deep into the wall. The amount of secondary waste gen...
