Abstract
Description
Technical Field
[0001] The invention relates to the technical field of waste treatment in radioactive sites, and more particularly to a gravity disconnection device used in high-radiation sites. Background Art
[0002] In high-dose places, such as equipment rooms and hot rooms, some cables (such as optical fiber cables for cameras, power cables for power devices, etc.) are inevitably introduced inside. After these cables are used, they cannot be directly transferred out of the hot room. They usually need to be cut and sorted before they can be transferred out of the barrel. This patent designs a gravity tangent device for hard cables that cannot be directly stored. Summary of the invention
[0003] The purpose of the present invention is to design a gravity tangent device so as to meet the requirements of high-dose places, long distances and indirect operations.
[0004] The technical solution of the present invention is as follows: a gravity wire breaking device used in high radiation fields, including a fixed plate, a lifting lug installed on the fixed plate, the lower end of the fixed plate is connected and fixed to a guide rod, a gravity block is sleeved on the guide rod, and a weight block operating ring is connected to the gravity block, and the upper end of the cutter head passes through the guide sleeve and is connected to the lower end of the guide rod.
[0005] The upper end of the cutter head passes through the guide sleeve and is connected with the lower end of the guide rod by a quick connection structure.
[0006] The guide sleeve is connected with the support plate and the support leg as a whole and is used to fix the guide rod so that the guide rod is in a plumb state.
[0007] A slide groove is arranged on the upper end of the cutter head, which is assembled with a top screw installed on the guide sleeve.
[0008] The distance between the lower end surface of the guide rod and the bottom of the cutter head is A, the height from the lower end of the support leg to the upper surface of the support plate is B, and A>B.
[0009] The distance from the fixed plate to the lower end of the gravity block is H, and the height of the gravity block is h. The gravity block is lifted to the upper part of the guide rod through the weight block operating ring. At this time, the height of the gravity block rises to the sliding height Hh, allowing the gravity block to fall freely.
[0010] The total height of the gravity disconnect device used in the high radiation field is determined according to the size of the storage barrel and the hot chamber item transfer interface.
[0011] The lifting lug, lifting lug fixing plate, guide rod, guide sleeve, support plate and support leg are made of stainless steel.
[0012] The gravity block is made of stainless steel with lead sand filled inside.
[0013] The cutter head is made of 07Cr 17 Ni 7AL.
[0014] The significant effect of the present invention is that the device does not require driving forces such as electricity, hydraulic pressure, and air pressure. With the assistance of the master and slave manipulators, it can cut the hot chamber cable in a high-dose place, over a long distance, and indirectly. At the same time, the device can be quickly disassembled and assembled to meet the requirements of storage. It has the characteristics of simple structure and strong applicability.
