Background

The method for transferring the waste barrel by adopting the roller way and the trolley is a popular waste barrel transfer method in the radioactive waste treatment of the nuclear power station at present.

At present, a waste barrel is widely applied to radioactive solid waste treatment as a solid waste outer package, and in order to reduce the exposure dose of workers and improve the automation level of waste treatment, a roller way and a trolley are generally used for realizing the transportation of the waste barrel at each radioactive waste treatment station.

The roller way and the trolley are centered and generally controlled by an electric switch or a mechanical limit switch. In practical application, the waste barrel is toppled when the roller way transfers to the trolley for a plurality of times due to the fault of the electric control system. The waste barrel transfer between the roller way and the trolley is controlled by the electric control system to have the waste barrel dumping risk, although the risk is very small, once the waste barrel dumping event occurs, consequences such as ground injury, waste barrel damage, radioactive waste scattering, factory building radioactive pollution and the like can be caused, and due to the particularity of radioactive operation, subsequent remedial treatment activities are very complex.

Detailed Description

The invention is further illustrated by the accompanying drawings and the detailed description.

As shown in fig. 1 and 2, the device is arranged between the roller way and the trolley.

The first roller way guide device 1 and the second roller way guide device 4 are arranged on two sides of the roller way rollers 2 and used for guiding and positioning the roller way rollers 2. The waste barrel 3 is arranged on the roller way rollers 2, and the rotation of the roller way rollers 2 drives the waste barrel 3 to move.

The trolley and the trolley rollers 7 below the trolley move through a trolley track I14 and a trolley track II 15 which are arranged on the ground, and are guided and positioned through a trolley guide device I5 and a trolley guide device II 6 on two sides.

The anti-tipping device 8 in this application is mounted between the trolley and the roller table.

As shown in fig. 2 and 3, the anti-toppling device 8 includes a base 16 fixedly installed (fixable to the ground), a guide 11 fixedly provided on the base 16, a spring 12 installed at the bottom of the guide 11, a stopper 10 installed above the spring 12 and located inside the guide 11, and a stroke controller 9 connected to the stopper 10.

The side wall of the guide 11 is formed with an opening having a length in the length direction, the stopper 13 is formed by horizontally fixing and welding the stopper in the side direction of the stopper rod 10, and the stopper 13 is located within the length range of the opening.

The stroke controller 9 is installed on the trolley, when the trolley moves along the trolley track I14 and the trolley track II 15, the stroke controller 9 and the stopper 13 are driven to run relatively, when the stopper 9 moves to the stopper 13 and continues to move, the stroke controller 9 generates downward pressure on the stopper 13, the stopper 13 is caused to move downwards, and meanwhile, the stop rod 10 is driven to move downwards.

The stroke controller 9 is installed on the trolley, and the installation height and the installation position of the stroke controller 9 ensure that when the trolley is aligned with the roller way, the lowest point, namely the lower edge of the stroke controller 9 is in contact with the limiting stopper 13, and at the moment, the anti-toppling device 8 is in a passing state.

The extension and contraction of the spring 12 will drive the stopper rod 10 to move up and down in the guide 11, and the stopper 13 is located in the opening, and the opening has a length, so that the guide 11 moves within the length range of the opening, and the upper and lower positions are both limited.

The anti-toppling device 8 has two states by the design of the structure: the first state is a 'blocking' state, namely the stop lever 10 is pushed to the highest position by the spring 12, the upper end of the stop lever 10 is higher than the upper surface of the roller way roller 2 or the trolley roller 7, and the stroke controller 9 is not pressed on the limiter 13; the second state is a 'pass' state, namely the spring 12 is compressed, the lowest point of the stroke controller 9 is pressed on the stopper 13, and the upper end of the stop lever 10 is lower than the upper surface of the roller way roller 2 or the trolley roller 7.

As shown in fig. 4, the blocking lever 10 installed on the guide 11 can move only up and down under the restriction of the guide 11, and there is a proper gap between the blocking lever 10 and the guide 11 for moving up and down flexibly. The spring 12 is arranged in the lower end of the guider 11, and the spring 12 gives the stop lever 11 a sufficient upward force to enable the ejector rod 11 to be at the highest position, so that the anti-toppling device is in a blocking state. At this moment, if the roller way is provided with the waste barrel 3, the roller way is started to rotate towards the direction of the trolley, and the waste barrel 3 is blocked, so that the waste barrel 3 is prevented from being toppled.

When the roller way and the trolley are not centered, the stroke controller 9 does not roll the limiter 13, the compression amount of the spring 12 is minimum, the stop lever 10 is located at the highest position, and the upper end of the stop lever is higher than the upper surfaces of the roller way roller 2 and the trolley roller 7. At this moment, the anti-dumping safety device is in a blocking state, the roller way is started, the waste barrel 3 is blocked by the stop lever 10, and the waste barrel 3 is prevented from being dumped from the roller way and falling to the ground.

As shown in fig. 5, when the trolley moves to the roller way along the trolley track one 14 and the trolley track two 15, the stroke controller 9 also moves along the roller way in the same direction because the stroke controller 9 is fixed on the trolley. When the stroke controller 9 moves to contact the stopper 13 and continues to move forward, the stopper 13 moves downward under the pressure of the stroke controller 9, the spring 12 is compressed, and the stopper 10 descends accordingly. When the lowest point of the stroke controller 9 contacts with the stopper 13, the stopper 13 is at the lowest point, the spring 12 reaches the maximum compression amount, the stop lever 10 descends to the lowest point, and the upper end of the stop lever is lower than the upper surface of the roller way roller 2. At this moment, the roller way and the trolley are aligned, the anti-dumping device is in a passing state, the roller way is started, and the waste barrel 3 is moved to the trolley.

The stopper 13 can be designed into a shape like a Chinese character 'yi' in fig. 2, or a shape like an 'L' in fig. 6, or other shapes according to actual conditions in the field.

As shown in fig. 6, the stopper 13 is an L-shaped plate fixed to one side of the stopper 10, and the stroke controller 9 is located on the L-shaped plate.

As shown in fig. 7, the stopper 13 is in another straight shape, and has positioning devices 18 and 19 at its two ends, respectively, and a sleeve 17 is sleeved outside and above which the stroke controller 9 is located. In this design, a first positioning device 18 is fixedly connected to the stop 13 for limiting the movement of the sleeve 17. The principle of the second positioning device 19 is the same as that shown in fig. 8 and 9. Compared with the situation without the sleeve 17, the stroke controller 9 moves relative to the limiter 13, the sleeve 17 rolls under the action of the stroke controller 9, sliding friction force is converted into rolling friction force, system resistance is reduced, and system operation flexibility is improved.

The stroke controller 9 moves on the stopper 13 to control the stopper 13 to move up and down, and the stop lever 10 is driven by the up-and-down movement of the stopper 13 to move up and down. The stroke controller 9 may be a wheel with a bearing, or may be in other forms as long as it can drive the stopper 13 to move up and down.

As shown in fig. 13, a wheel 23 with a bearing 22 is used as the stroke controller 9, the wheel 23 is mounted on a shaft 24, and the wheel is rotated by mounting the bearing 22. The use of the bearing 22 reduces the frictional resistance of the stroke controller 9 and improves the operational flexibility thereof.

As shown in fig. 10 and 12, the stroke controller 9 is an inverted triangular plate, a small wheel 20 is mounted at the end of the stopper 13, the small wheel 20 is a concave wheel, and the lower end plate surface of the stroke controller 9 is in contact with the concave groove. The function of the small wheel 20 is mainly to increase the flexibility, which is similar to the sleeve 17.

As shown in fig. 11, another design of the stroke controller 9 is that it is installed below the stopper 13, and a support 21 is fixedly installed below the stopper 13, the support 21 connects the stopper 13 with the stopper rod 10 by a hinge, and by leverage of the support 21, the stopper rod 10 compresses the spring 12 and moves downward when the stroke controller 9 pushes the stopper 9 downward. The stroke of the lever 10 is amplified due to the lever action.

The stop 13 is fixed on the ground close to the roller table by a support, and the stroke controller 9 is installed on the trolley. That is, the stroke controller 9 follows the movement of the cart.

The stroke controller 9 rolls across the plane of the stopper 13, the installation height of the stopper 13 should be lower than the leftmost edge or the rightmost edge of the stroke controller 9 and higher than the lowest edge of the stroke controller 9, and the height difference h between the initial position 13 of the stopper 13 and the lowest point of the stroke controller 9 is the stroke of the stop lever 10. It can be seen that: the stroke of the stop lever 10 is related to the radius and the installation height of the stroke controller 9; the radius of the stroke controller 9 is the limit stroke of the stop lever 10; the stroke of the stopper bar 10 can be adjusted by adjusting the installation height of the stroke controller 9.

Install stopper 13 on roller bed side ground, stroke controller 9 installs on the dolly for prevent that garbage bin 3 from preventing to topple over outward from the roller bed to dolly transportation in-process, in addition the following condition:

firstly, the stopper 13 is arranged on the trolley, the stroke controller 9 is arranged on the side of the roller way, the ground stopper 13 moves along with the trolley, and the stroke controller 9 is fixed on the ground and can be used for preventing the waste barrel 3 from toppling over from the trolley to the roller way in the process of transferring;

two sets of limiters 13 and the stroke controllers 9 are oppositely arranged on the trolley and the ground on the roller way side, namely, one set of the stroke controllers 9 is arranged on the trolley, and the other set of the stroke controllers 9 is arranged on the ground on the roller way side, so that the anti-toppling problem of transferring the waste barrel in two directions can be prevented.

And a guide 11 for controlling the movement trace of the stop lever 10 so that it can move only in the direction limited by the guide 11. The side surface of the guide 11 is provided with a groove for controlling the upper limit position and the lower limit position of the limiter 13 and controlling the motion track of the limiter 13, so that the limiter can only move longitudinally and can not move transversely. The contact parts of the guider 11, the stop lever 10 and the limiter 13 are provided with proper gaps. The guide 11 is mounted on the base 16, and the connection mode can be selected according to the actual situation, such as welding.

And the spring 12 provides continuous upward force for the stop lever 10 to push the stop lever 10 to the highest position, so that the device is automated.

The automatic waste barrel transfer device has the advantages that the automation is realized by adopting the relative motion of the spring and the equipment, only when the roller way and the trolley are centered, the waste barrel can be transferred between the roller way and the trolley, the safety and reliability of the transfer of the waste barrel on the roller way are improved, and the problem that the waste barrel is toppled when the roller way and the trolley are not centered is fundamentally solved, so that the automatic waste barrel transfer device is very practical.

As long as the anti-toppling safety device is designed between the roller way and the trolley, the liftable stop lever is adopted to control the waste barrel to transfer, the stop lever is automatically reset by utilizing a spring or other automatic equipment (including gravity), and the stop lever is controlled to descend by the stroke controller through the relative position of the roller way and the trolley, and the stop lever falls within the protection range of the invention no matter the specific size, the number, the material, the shape, the connection mode and the like are different, such as an L-shaped limiter, a non-circular stroke controller and the like.

The waste barrel is transported by adopting the roller way and the trolley and is widely applied to the field of radioactive waste treatment, and the device is simple to build, convenient and reliable to use, can be widely applied to radioactive waste treatment of nuclear power stations and can also be applied to other industries with similar requirements.
