Description

Technical Field

[0001] This utility model belongs to the field of nuclear power waste container transfer technology, and in particular relates to a nuclear power waste container transfer device. Background Technology

[0002] Nuclear waste containers are primarily used to store nuclear waste generated during the production process of nuclear power plants. At this stage, the nuclear waste has already been cooled and needs to be mixed with special materials before being packed into containers and placed in suitable areas for deep burial. During the transfer of nuclear waste containers onto and off vehicles or for deep burial, mechanical structures are used for lifting and rigging to minimize the distance between operators and the containers.

[0003] In existing technologies, non-powered grippers are typically used to lift nuclear waste containers. The diameter of the lid on top of these containers is usually larger than the diameter of the container itself. The grippers can lift the containers by opening and closing the lid. However, most non-powered grippers in existing technologies use a single structure and can only grip nuclear waste containers within a certain diameter range, thus limiting their applicability.

[0005] A connector, comprising a floating sleeve, a main rod, and a base; the floating sleeve is nested around the periphery of the main rod and slides along the axial direction of the main rod.

[0006] The linkage rod and the support form a clamping unit and are arranged in a ring array around the connector; one end of the support is fixedly connected to the base, one end of the linkage rod is hinged to the floating sleeve, and the end of the support away from the base is provided with several sets of limiting holes. The linkage rod is hinged to different limiting holes according to the clamping diameter.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] This utility model embodiment provides a nuclear power waste container transfer device, such as... Figures 1-6 As shown, the nuclear waste container transfer device is used for lifting and moving nuclear waste containers. The nuclear waste container includes a container body 420 and a cover 410 larger than the container body 420. Here, the diameter of the cover 410 is larger than that of the container body 420. The nuclear waste container transfer device includes:

[0028] Connector 100, comprising a floating sleeve 110, a main rod 120 and a base 130; the floating sleeve 110 is nested around the main rod 120 and slides along the axial direction of the main rod 120.

[0029] The linkage rod 300 and the support 200 constitute a clamping unit. The number of clamping units is not less than four and they are arranged in a circular array around the connector 100. One end of the support 200 is fixedly connected to the base 130, and one end of the linkage rod 300 is hinged to the floating sleeve 110. The end of the support 200 away from the base 130 is provided with several sets of limiting holes 202. The linkage rod 300 is hinged to different limiting holes 202 according to the clamping diameter.

[0030] The linkage 300 includes a clamping rod 310, a support rod 320 and a hinge seat 330. The hinge seat 330 is fixed to the side wall of the floating sleeve 110. The support rod 320 and the hinge seat 330 are connected by a hinge. The other end of the support rod 320 is also hinged to the clamping rod 310.

[0031] The floating sleeve 110 is provided with a lifting ring connecting seat 140 for connecting ropes at the end away from the base 130. Generally, a crane or other lifting equipment is used to tie the lifting ring connecting seat 140 with ropes. When the nuclear waste container transfer device is lowered as a whole, the base 130 will abut against the upper surface of the cover 410. As the floating sleeve 110 descends, the linkage rod 300 will be activated due to the traction of the floating sleeve 110, and the clamping rod 310 will move away from the base 130, thereby allowing the clamping rod to move away from the base 130. The rod 310 is nested on the outside of the cover 410. When the floating sleeve 110 is lifted again under the action of external force, the floating sleeve 110 will lift the clamping rod 310 closer to the base 130. At this time, the clamping rod 310 is already nested on the outside of the cover 410. When it re-performs centripetal movement, it will engage on the outside of the cover 410. As the floating sleeve 110 rises, the clamping rod 310 will abut against the part of the cover 410 that exceeds the barrel 420 and provide lifting force to the nuclear waste barrel.

[0032] In this embodiment, the number of limiting holes 202 is several groups and they are arranged on the support 200. The support 200 is provided with a deflection groove 201 at the end away from the base 130. The deflection groove 201 is equivalent to an opening in the support 200. The opening is used to accommodate the clamping rod 310 passing through the support 200.

[0033] The clamping rod 310 passes through the deflection groove 201 and is hinged to the support 200 via the limiting hole 202. By changing the relative position of the clamping rod 310 and the support 200, the distance between the clamping rod 310 and the base 130 can be changed. This allows the clamping rod 310 to clamp more sizes of nuclear waste containers, increasing the application range of the equipment. During the hoisting process, the size of the clamping area formed by several sets of clamping rods 310 can be adjusted to meet the clamping needs of more sizes of nuclear waste containers.

[0034] In a preferred embodiment of this invention, the second hinge hole 302 is provided at the connection between the inclined rod 311 and the L-shaped rod 312, and the connection between the inclined rod 311 and the L-shaped rod 312 is the middle section of the clamping rod 310; the inclined rod 311 is provided with a first hinge hole 301 at the end away from the second hinge hole 302, and the inclined rod 311 is hinged to the support rod 320 through the first hinge hole 301;

[0035] In this embodiment, the pin used to fix the clamping rod 310 and the support 200 extends through the limiting hole 202 to the deflection groove 201, and passes through the clamping rod 310 located in the deflection groove 201 using the second hinge hole 302; the hinge structure in this application is implemented using the existing pin structure.

[0036] In a preferred embodiment of this invention, the main rod 120 includes a limiting rod 121 and a sliding rod 122. The diameter of the limiting rod 121 is larger than the diameter of the sliding rod 122. The floating sleeve 110 is provided with a partition plate near the base 130. The partition plate is integrally formed with the floating sleeve 110. The partition plate accommodates the through hole through which the sliding rod 122 passes. The limiting rod 121 is located inside the floating sleeve 110. One end of the sliding rod 122 is fixedly connected to the limiting rod 121, and the other end extends out of the floating sleeve 110 through the through hole and is connected to the base 130.

[0037] In this embodiment, the outer diameter of the base 130 is larger than the outer diameter of the floating sleeve 110. The lifting ring connecting seat 140 is composed of a bolt segment, an outer plate and a lifting ring. The bolt segment is assembled inside the floating sleeve 110 by a threaded connection. The inner wall of the floating sleeve 110 is provided with a thread that matches the bolt segment.
