Problems solved by technology

However, the current research and development technology of anti-radiation hoisting devices in China is immature and cannot meet the hoisting work of radiation devices in deep well radiation environments.
The current method has the disadvantage that the suspension rope shakes a lot, and it is easy to deviate and wind when the steel wire rope is rewound, which will damage the suspension wheel and the steel wire rope; Low, small adjustments will also give a great acceleration to the sling, increasing the sway of the rope and other deficiencies

Embodiment 1

[0049] Example 1 A hoisting device for a neutron beam window maintenance platform working under radiation

[0050] The technical scheme of the present invention is described in detail below:

[0051] Such as figure 1 , figure 2 and image 3 As shown, a neutron beam window maintenance platform hoisting device working under radiation includes a bottom plate 1, and the two ends of the bottom plate 1 are respectively provided with a wire rope winding device 2 and a driving device 3 for driving the wire rope winding device. The middle part of 1 is provided with the wire tube storage device 4 for storing the wires and gas pipes of the neutron beam window maintenance platform 6 . Since the neutron beam window maintenance platform 6 has a lot of wires and gas pipes, during the hoisting process, the present invention can rewind and retract the wires and gas pipes of the neutron beam window maintenance platform 6 in time through the wire tube storage device 4 to improve work efficie...

Embodiment 2

[0060] Example 2 A hoisting device for a neutron beam window maintenance platform working under radiation

[0061] In order to further ensure the hoisting effect, on the basis of Embodiment 1, the present invention may be provided with a wireless inclination sensor for measuring the inclination angle of the hoisting device and a height sensor for measuring the height of the hoisting device on the bottom plate 1 . The inclination sensor and height sensor are wirelessly connected to the controller. Send the tilt angle and height information to the controller, which is convenient for real-time monitoring and understanding of the general position of the hoisting device, so that the staff can keep abreast of the working status.

[0062] In order to further ensure the radiation protection effect during hoisting, on the basis of Embodiment 1, the outer surfaces of the servo motor and the reducer are sprayed with a radiation protection layer with a thickness of 1-3 mm. The anti-radia...

Abstract

The invention discloses a lifting device and a lifting method for a neutron beam window maintaining platform working under irradiation. The lifting device comprises a bottom plate, wherein the two ends of the bottom plate are equipped with a steel wire rope winding device and a drive device for driving the steel wire rope winding device; the middle part of the bottom plate is equipped with an electric wire for taking and placing a neutron beam window maintaining platform and a wire tube storage device for a gas tube; a lifting wheel and a supporting base are arranged on the steel wire rope winding device; the lifting wheel is arranged on the supporting base through a lifting wheel shaft; a plurality of threaded slots are formed in the lifting wheel; a lead screw is arranged at one side ofthe lifting wheel; a screw shaft ring sleeves the lead screw; a guide sleeve is arranged on the screw shaft ring; and the guide sleeve is adaptive to a threaded slot in the lifting wheel. According tothe lifting device disclosed by the invention, the steel wire rope is uniformly wound on the lifting wheel back and forth through the steel wire rope winding devices, so that problems such as disordering, inclined pulling, winding and stacking are avoided, and therefore, lifting balance and stability can be improved, irradiation accumulated dose of the lifting device and an operator is shortened,and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of remote control maintenance under radiation environment. More specifically, it relates to a hoisting device and hoisting method for a neutron beam window maintenance platform working under radiation. Background technique [0002] Neutrons are one of the important probes for people to understand the microstructure and motion state of matter. Neutron beam window inserts operate in high-radiation areas for a long time. It is necessary to consider the impact of radiation damage on its life, and consider routine maintenance and replacement in the design. Since component materials will cause induced radioactivity (i.e. activation) after being irradiated in high-radiation areas, the maintenance and replacement of those activated or surface-contaminated components must be operated remotely under protective conditions to avoid radiation hazards to maintenance personnel. However, the current research and developme...
