Problems solved by technology

[0005] In order to realize the above-mentioned horizontal transportation of radioactive material transfer lead tanks into and out of the hot cell, it is generally necessary to set up a fixed transportation track to connect the inside and outside of the hot cell. Although the purpose of horizontal transportation is achieved in this way, it causes problems including the requirement that the indoor and outdoor sites have the same elevation. 1. The installation position of the track cannot be used for other purposes, the radiation protection inside and outside the hot room, and the decline in the airtight function index. The present invention provides a flipping and folding track for receiving the hot room

Embodiment 1

[0032] Such as figure 1 with 2 As shown, an overturning and folding track for a heat receiving chamber includes a track body on which a steel rail for a traveling vehicle is provided. The track body includes a fixed track portion 12 and an overturned track portion 13. The fixed track The portion 12 and the turning rail portion 13 are hingedly connected by a first hinge shaft 8, and the steel rail includes a first steel rail provided on the fixed rail portion 12 and a second steel rail provided on the turning rail portion 13;

[0033] The fixed rail part 12 is further provided with a fixing part, and the fixing part is used to fix the fixed connection between the rail part 12 and the surface of the heating chamber and / or the accessories in the heating chamber;

[0034] The turning rail portion 13 is further provided with a leg 6 which is used for supporting the turning rail portion 13 in the use state of the turning and folding track.

[0035] In this embodiment, one side of the fixed...

Embodiment 2

[0040] This embodiment is further limited on the basis of embodiment 1, such as figure 1 with 2 As shown, as a specific implementation form of the fixing part, the fixing part includes a backing plate 1, a connecting bolt 3, and a pressure block 2. The pressure block 2 is bolted to the backing plate 1 by a connecting bolt 3, and the first rail The compressive stress provided by the pressing block 2 is fixed on the backing plate 1. In the above implementation form, the backing plate 1 can be fixed on the bottom surface of the cement floor of the heating chamber by anchor bolts or ground anchors, or fixed on the stainless steel cladding surface of stainless steel by welding connection, and the second is realized by connecting bolts 3 and pressing blocks 2. The fixing of a steel rail on the backing plate 1 facilitates the formation of a detachable connection form between the first steel rail and the backing plate 1. In order to facilitate compaction and fixation, the first steel ra...

Embodiment 3

[0048] This embodiment is further limited on the basis of any one of the technical solutions provided by any of the above embodiments, such as Figure 1 to Figure 3 As shown, as a technical solution that facilitates the smooth movement of the vehicle on the flip-folded track and does not require an excessively wide track surface of a single rail, there are two rails, and the two rails are parallel to each other, and the two first rails are both fixed It is connected to the fixed part and further includes a connecting rod 5 arranged between the two second steel rails, and different ends of the connecting rod 5 are respectively fixedly connected to different second steel rails.

[0049] In order to facilitate the vehicle to leave or drive onto the inverted and folded track, the free end of the second steel rail is also provided with an inclined rail 11 whose track surface is an inclined surface. The free ends of the two steel rails are connected.

Abstract

The invention discloses an overturning folding rail for a receiving hot cell, and can be used for design and application of an overturning folding rail in an open radiation laboratory or a reactor auxiliary facility, which is used in the process transportation process of entering and exiting the receiving hot cell by using a lead jar as a container for loading a radioactive substance. The overturning folding rail can organically combine process transportation of the radioactive substance in the hot cell, transshipment and receiving of the lead jar and radiation protection of the hot cell, so that a lead jar transport vehicle can easily enter and exit the hot cell, and on the basis of transportation continuity, optimization of space usage and protection of ionization radiation are ensured. The overturning folding rail has high universality when being applied to the open radiation laboratory or the reactor auxiliary facility, has functions of transshiping and receiving various radioactive substance, can optimize adaptability of process transportation and architectural layout of the facility, and finally obtains technical innovations on the process transportation and good economic benefits.

Description

Technical field [0001] The invention relates to the technical field of rail transportation of radioactive material transfer lead tank trucks in open radioactive laboratories or reactor supporting facilities, and in particular to an overturning and folding rail for receiving hot cells. Background technique [0002] In the design of open radioactive laboratories or reactor supporting facilities, process transportation is one of the very important links. A transportation organization with reliable functions and good structures that meets radiation protection requirements is a prerequisite and condition for other process operations. The key factor to ensure the smooth operation of the test facility. [0003] There are many ways and methods for the transfer of radioactive materials to the hot cell, but there are quite a few occasions that require the use of lead tanks as containers to load radioactive materials into and out of the hot cell. Generally speaking, special attention should b...
