Description

The invention relates to refueling technology, in particular to devices designed to combine the axes of one product with another when overloading products located in any containers, and can preferably be used in a fast fast neutron nuclear reactor with a heavy liquid metal coolant to extract side reflectors.

The prior art is known induction device (patent RU No. 2487832 C1, B66C 1/66, publ. 07/20/2013), containing a base, large and small rotary plates with offset axes of rotation and drives, providing access to a given coordinate, and a guide pipe for direction of movement of the capture. The guide tube is made with the possibility of passage through the covers of the control and protection system (CPS) and docking with the head of the spent fuel assembly, installed in the housing associated with a small rotary plate. The drive movement of the guide tube is made in the form of a screw mechanism.

However, the disadvantage of this guidance device is the inability to place the guide tube of the guidance device along the axis of the side reflector near the wall of the reactor monoblock, because The CPS cover interferes, which is due to the tightness of the layout elements of the reactor monoblock.

Known induction device for extracting side reflectors (patent RU No. 2581100 C1, B66C 1/66, publ. 04/10/2016) containing a base, a rotary plate with a drive that provides access to a given coordinate, a guide tube for the direction of movement of the capture in the form of a telescope and telescope movement mechanism. In this case, the telescope is a telescope column formed by at least two telescopically connected pipes, with an element to ensure engagement with the grip. The telescope is mounted on a trolley of the telescope moving mechanism, linearly moving along the rolling guides located on the turntable. The drive mechanism for moving the telescope is made in the form of a screw mechanism.

However, due to the fact that the clutch engages with the telescope with its console, due to the significant dimensions of the telescope column, as well as the misaligned location of the screw drive relative to the telescope, jamming is possible during operation of the device. And the presence of a linear mechanism for moving the telescope trolley greatly complicates the design, especially if it becomes necessary to seal the operation of this device.

The basis of this technical solution is the task of expanding the arsenal of technical equipment of a similar purpose, which consists in developing a device for combining the axes of one product with another, which allows overloading products located on the periphery (near the walls) of the tank, with the possibility of positioning the guiding element with the required accuracy.

The technical result consists in expanding technological capabilities while improving the accuracy of guidance, reliability and safety.

The problem is solved in that the positioning device contains a large and small turntable with drives that provide access to a given coordinate in the service area. Moreover, a large rotary plate concentrically rotates relative to the axis of the container from which you want to remove the product. A cover is installed on the large rotary plate to cover the small rotary plate, with a docking device mounted on it, and having a seat for docking with the transfer container. The small rotary plate is provided with a through figured groove for the passage of the gripper with the removable product. The axis of rotation of the small turntable is eccentric relative to the axis of rotation of the large. A double telescopic device for carrying out cargo operations is installed on a small rotary plate, driven, in the particular case of execution, by a chain transmission. The telescopic device is made in the form of cylindrical guides with sliding rods mounted in them, driven by a chain drive from a drive mounted on the lid. At the same time, a fork is installed at the ends of the sliding rods and between the telescopic rails, which ensures its adhesion to the gripping device when turning a small turntable. The fork of the telescopic device is equipped with catchers and receiving cylindrical grooves, which provide a combination of gripping and telescopic devices with the possibility of joint movement.

When using the invention, technical results can be additionally obtained, which in particular are expressed in simplifying the design and improving the manufacturability of the positioning device.

Technical results are achieved:

- the implementation of the movement mechanism with the possibility of movement around the circumference of 360 °, which allows access to the coordinate of products located on the periphery (near the walls) of the tank, which in turn expands technological capabilities in terms of the unique positioning of the device relative to the walls of the tank while improving the accuracy of pointing telescopic device;

- the use of a small rotary plate located under the cover and a docking device placed on it, which simplifies the design of the device and improves the manufacturability of the manufacturing positioning device;

- the use of a dual telescopic device, which increases the reliability and safety of work;

- supplying the telescopic device with a fork with catchers, which prevents the fall of the grip with the unloaded product, and accordingly also increases the safety of work.

The positioning device (Fig. 1, 2 and 3) contains a base 1 (Fig. 1, 2 and 3), a large 2 turntable (Fig. 2 and 3) with a supporting rotary device 3 and a drive 4 (Fig. 3), a small 5 a rotary plate (Fig. 3) with a supporting rotary device 6 and a drive 7 (Fig. 3), a cover 8 (Fig. 3) with a docking device 9 (Figs. 1 and 3), which ensure docking and fixing with a transfer container (conditionally not shown), a telescopic device 10 (Fig. 1) with extendable rods 11 (Fig. 1 and 3), controlled in the particular case of chain drive 12 (Fig. 3). On the lower part of the pull-out rods 11 of the telescopic device 10, a fork 13 is mounted (Figs. 3, 4 and 5), which is equipped with catchers 14 and receiving elements 15 (Fig. 5).

Big 2 and small 5 rotary plates with corresponding supporting rotary devices 3 and 6 have their own independent axis of rotation. The motion paths of the docking device 9 and the telescopic device 10 are shown in FIG. 6.

Drives 4 and 7, corresponding to large 2 and small 5 rotary plates, provide access to a given coordinate in the service area.

Large 2 rotary plate concentrically rotates relative to the axis of the tank (not shown conditionally), from which it is necessary to remove the product. Small 5 rotary plate is equipped with a through curly groove E (Fig. 6) for the passage of the gripping device. The axis of rotation of the small 5 turntable is eccentric relative to the axis of rotation of the large 2 turntable.

A telescopic device 10 for carrying out reloading operations, driven by a chain gear, is mounted on a small 5 rotary plate. The telescopic device 10 is made in the form of double cylindrical telescopic guides 16 (Fig. 1) with mounted pull-out rods 11, driven by a chain drive from a chain drive 12, which is mounted on the cover 8 and located inside the telescopic guides 16. sliding rods 11 and between the telescopic rails 16 installed fork 13, which provides when turning the small 5 of the rotary plate clutch with a gripping device (not shown conditionally) in zone G (Fig. 6) its pre th location.

The catchers 14 and the receiving elements 15 of the plug 13 (Fig. 5) provide a combination of the gripping and telescopic 10 devices with the possibility of their joint movement. The receiving elements 15 are made cylindrical in accordance with the reciprocal place on the grip, which is made in the particular case of the execution of also a cylindrical shape. Another embodiment is also possible, for example, a hexagonal shape.

A cover 8 is mounted on the large 2 turntable, covering the small 6 turntable. On the cover 8 is mounted a docking device 9 (Fig. 3), having a seat for docking with a reloading container. The docking device 9 (Fig. 3) is intended for sealing the internal space of the served tank (if necessary), as well as for positioning the transfer container on it.

At the same time, the gripping device, which is used for reloading the products, is suspended on the winch cable of the reloading container (not shown conventionally) with the possibility of connecting the telescopic device 10 with the fork 13 as a whole using mounting elements in zone G (Fig. 6).

The positioning device operates as follows.

A pre-positioning device is installed on the container from which it is necessary to reload the products. Then the large 2 rotary plate is rotated to the position necessary for reloading the product from the container, after which a reloading container (not shown) is installed on the docking unit 9.

In the initial position, the telescopic device 10 is in the folded state, while the surface AND of the plug 13 (Fig. 5) abuts against the end surface K of the telescopic device 10 (Fig. 3).

First, the small 5 rotary plate is rotated by an angle a (Fig. 6) counterclockwise around the slewing device 6 by means of the actuator 7 so that its curly groove E allows the gripper to pass into the engagement zone with the fork 13 of the telescopic device 10. Then the gripping device is lowered by means of a winch of a transfer container (not shown) through the open hole of the gate 9 to the required depth. Next, the small 5 rotary plate is returned to zone G, where the catchers 14 of the fork 13 are hooked to the mounting elements (not shown conventionally) of the gripping device and fall into the location zone of the receiving elements 15 of the fork 13. There is a combination of their axes and the coupling of the fork 13 with the gripping device. The gripping device is fixed with a fork 13 of the telescopic device 10 by means of receiving elements 15 with a certain vertical movement of the gripping device until the cable loosens, which is provided by the winch of the transfer container. Next, the gripping and telescopic 10 devices are jointly set to the required coordinate by turning the small 5 swivel plate at an angle b (Fig. 6) and the large 2 swivel plates around the slewing devices 3 and 6 using the corresponding drives 4 and 7. The gripper installed in this way and the fork 13 of the telescopic device 10 are jointly lowered, for example, to the head of the unloading side reflector, by means of the winch of the transfer container, and also by means of a chain drive 12 by moving the extension rods 11 .

The release of the gripping and telescopic 10 devices occurs in the reverse order.

Thus, the claimed design of the positioning device allows you to overload products located on the periphery (near the walls) of the tank, accurately and more reliably. It also allows technological guidance to the axis of the gripper, which generally improves reliability and safety while expanding technological capabilities.
