Description

The utility model relates to load-gripping equipment, in particular to devices for gripping a container lid, and can be used in slotting devices for slotted lids of containers for storing radioactive waste (RAW) forming slotted cavities with them, and used on their packaging processing lines, as well as in the equipment of manipulators, in slotted grips during loading and unloading operations in lifting and transport equipment in various industries.

An analysis of the state of the art in this area showed that a gripping device for closing and opening the lid of a container for storing solid radioactive waste is known, comprising a traverse with gripping mechanisms fixed to it, a locking mechanism for locking the position of the gripping mechanisms connected to the lifting and lowering device (Japanese Patent No. 2 -33120 B4, IPC: G21F 9/36, publ. 12/20/84)

The impossibility of the said device achieving a technical result provided by the claimed design is caused by the fact that the product of the analog device is designed for the presence of a bandage on the cover, which complicates the design, and is also equipped with additional electromagnetic elements, which complicates the design and increases its cost. In addition, it does not provide for the possibility of gripping a cover forming a slotted cavity with a container.

A device for capturing the lid of a container with radioactive waste, containing a traverse with a gripping mechanism fixed to it, a mechanism for fixing the position of the gripping mechanisms connected to the lifting and lowering device (German Patent No. 4034719 A1, IPC: G21F 5/14, B66B 1/00, publ May 7, 1992).

The impossibility of the said device achieving a technical result provided by the claimed design is caused by the fact that the gripper of the analog cover is structurally complicated due to the functional need to move it not only vertically to raise and lower, but also to move in the horizontal plane, which requires additional structural elements and increases the cost of the gripper. In addition, the analog product captures by attaching a cover in its central part, which reduces the safety of the operation.

Known gripping mechanism for opening the lid of containers with radioactive waste, containing a traverse with gripping levers fixed to it with clamping ends, a locking mechanism for locking the position of the gripping levers mounted on a traverse connected to a lifting and lowering device (Japanese Patent No. 5083160 B4, IPC: G21F 9/36 5/14, publ. 12/25/87).

The inability to achieve the technical result by the said device, provided by the claimed design, is caused by the fact that the analog design requires an additional mechanism on it in the form of a central handle to capture the cover, which complicates the design and reduces the reliability of the grip. This design is not designed to capture the lid, forming a slot cavity with the container.

Of the known technical solutions, the closest to the claimed one is a gripping device containing at least one yoke with gripping arms pivotally attached to it with clamping ends, and movably articulated at the other ends

by means of horizontal axes of interaction with rods pivotally connected to the slider of the mechanism for fixing the position of the gripping levers mounted on the traverse, and connected to the lifting and lowering device, the limiting mechanism (USSR Author's Certificate No. 446460, IPC: В66С 1/30, 1/44, publ 10/15/1974 Bull. No. 38).

The impossibility of the said device achieving a technical result provided by the claimed design is due to the fact that the prototype design provides for the lifting of goods without tipping above the center of gravity of the cargo with shortening of the gripping levers and rods, which reduces the reliability of the grip. The presence of spring elements in the structure of the prototype when lifting concrete covers can lead to structural failure, which also reduces the reliability of the load and the safety of the work. In addition, when lifting goods, in the form of a slotted lid forming a slotted cavity along the perimeter with the container in which it is installed, it will take considerable time to get into the cavity with gripping levers.

When developing the claimed design, the task was to ensure the capture of slotted covers with their vertical raising and lowering while improving reliability and ensuring quick capture.

In solving this problem, a technical result was achieved, consisting in the development of the design of the gripping device equipped with locking devices that allow you to roughly guide the gripping device, as well as slotted latches entering the slotted cavity, which allows you to simultaneously accelerate the entry of the clamping ends of the lever system into it, fix them position relative to the cover and at the same time prevent jamming in the cavity of the gap, which increases the reliability of the device.

The technical result is achieved by the fact that the gripping device of the slotted lid of the container contains at least one traverse with gripping arms pivotally attached thereto with clamping ends and movably articulated by other ends by means of horizontal axes of interaction with rods pivotally connected to the slide of the fixing mechanism the position of the gripping levers mounted on the traverse, and connected to the lifting and lowering device, a limiting mechanism.

New in the device is that it contains mounted on the traverse, at least a pair of locking devices with coaxial guide rails made with the possibility of their free passage and with beveled installation planes and at least a pair of coaxially located slotted retainers made with the possibility of their free passage and the lower ends of which are located above the lower ends of the guide clips, and each rod is equipped with a longitudinal groove optimal length, made with the possibility of movement in each of them corresponding to the horizontal axis of interaction.

In addition, the locking device may include support racks rigidly connected to the guiding latches and mounted on the traverse, the locking mechanism for locking the position of the gripping levers may include a hollow strut with a hole interacting with a rotary axle mounted on a hollow strut, with a ratchet sprocket installed with the possibility of interaction with the pusher mounted on the slider, and with the hole of the slider made telescopically connected with the cavity of the hollow pillar, the lower edge of the pusher The la and the upper edge of the slider opening are located in the same plane, and the hollow pillar can be equipped with a viewing window.

The restrictive mechanism can be made in the form of a vertical groove of a hollow rack with a horizontal axis located in it, mounted on a slider.

The gripping levers and rods may be mutually symmetrical with respect to the longitudinal axis of the locking mechanism of the gripping levers, and the locking devices and slotted latches may be mutually symmetrical with respect to the ends of the beam.

The lifting and lowering device can be made in the form of a hook, freely located on a horizontal frame, movably mounted in vertical guides.

The possibility of free passage of the guides and slotted clips can be ensured by the presence of gaps between the guide clip and the container and, respectively, the container and the lid, and the optimal length of the longitudinal groove may be due to the height and width of the slotted cavity between the lid and the container.

The articulated-movable fastening of the gripping levers on the traverse can be performed at its respective ends, and the mechanism for fixing the position of the gripping levers can be connected to the lifting and lowering device by means of a holder.

The gripping device for the slotted lid of the container is shown in the drawings, which depict:

Figure 2 is a top view of the device;

Figure 3 is a view of the device on the left;

Figure 4-7 - corresponding cycles 1-1U of the operation of the locking mechanism;

Fig.8 is a section aa in Fig.5.

The gripping device is designed for the slotted lid 1 of the container 2, forming along its perimeter a slotted cavity 3 with the container, which is subsequently to be sealed, for example

technological line (not shown) of the packaging of the container with radioactive waste. It is freely suspended on a lifting and lowering device containing a gripping hook 4 mounted on a horizontal frame 5 movably mounted in vertical guides (not shown in the drawing). The slotted lid 1 with the container 2 is made, for example, of concrete. The gripping device comprises at least one traverse 6 (FIG. 1), a linkage mechanism and a four-stroke locking mechanism 7 of the position of the gripping levers. Traverse 6 is a supporting structure of two parallel horizontal channel beams 8 and 9 (Figure 2), in the central part of which there is a locking mechanism 7 of the position of the gripping levers, including a box-shaped hollow vertical rack 10 (Figure 1, 8), mounted on the traverse 6, and made with a hole 11 (Figs. 4, 6), for example, in the form of a rectangular cutout in the side wall 12 (Fig. 4), a vertical groove 13 and a viewing window 14 (Fig. 8) on the front wall 15, and, located inside the rack, telescopically connected with it box slider 16 ( ig. 1, 8), as well as a fixing unit, including a rotary sprocket-ratchet 17 mounted on a horizontal axis 18, mounted on the inner wall of the strut 10 (Fig. 8), and with the possibility of its interaction with the pusher 19, mounted on the inner wall the slider 16, and with the lower plane of the hole 11. In the side wall 20 (Figure 5) of the slider 16, interacting with the wall 12 of the rack 10, a hole 21 is made, for example, in the form of a rectangular cutout corresponding to the hole 11 and configured to interact with the sprocket ratchet 17. Pusher L 19 is located so that its lower edge and the plane of the upper edge of the holes 21 of the slide are in the same horizontal plane. In the vertical groove 13 of the rack 10 there is a horizontal axis 22 mounted on the inner wall of the slider 16. In the body of the slider 16, a hole 23 is made on its rear wall (Fig. 8) for the passage of the axis 18 of the sprocket-ratchet 17, and on the front wall

a vertical groove 24 and a window 25, the location of which corresponds to the location of the vertical groove 13 and the viewing window 14 of the rack 10.

The hinged-lever mechanism is made in the form of a pair of two-arm levers, each of which contains an upper link 26, the upper end articulated with a slider 16 connected to the hook 4, and the lower end pivotally movable through the horizontal axis of interaction 27 with the upper ends of the gripping levers 28, the lower ends of which are pivotally mounted on the corresponding ends of the channel beams 8 and 9 of the traverse 6, and on the inclined edges 29 of which the clamping ends 30 are mounted. The shape of the clamping ends 30 can be made from the side under imaemoy cap corresponding to the shape of its surface, e.g., a zigzag. The gripping levers 28 and rods 26 are arranged mutually symmetrically with respect to the vertical longitudinal axis O-O of the locking mechanism 7 of the position of the gripping levers.

In the lower part of the rods 26, a longitudinal groove 31 is made in each, the lower cutout of which covers the horizontal axis of interaction 27, with the possibility of its movement in each groove along it to the distance of the optimal groove length, determined by the dimensions of the height and width of the slot cavity 3 between the lid 1 and the container 2 to eliminate jamming stop clamping ends 30 on the wall 32 of the container 2 in the slotted cavity 3 (Figure 1).

At the respective ends of the channel beams 8 and 9 of the traverse 6, fixing devices 33 are rigidly fixed at least in a pair at each end of the traverse 3, including each guide pin 34 coaxially located relative to the vertical axis OO of the gripping device, made with a beveled installation plane 35 from the side the location of the container, and rigidly mounted on the support posts 36, rigidly attached to the traverse, as well as at least a pair of coaxially located relative to the axis OO

slotted latches 37, rigidly fixed to the support racks 38, mounted on the traverse. The locking devices 33 with the guide clips 34 and the slotted clips 37 are mutually symmetrical with respect to the ends of the beam. The horizontal lengths of the support posts 36 and 38, as well as the removal of the guides 34 and the slotted 37 latches from each other, are selected in each case depending on the dimensions of the container and the lid, but it is always possible to freely pass the guides 34 and the slotted 37 latches due to the presence of the gap, respectively, between adjacent walls of the container and the latch 34, for example, within 50 mm, and also between the walls of the container 32 and the side wall of the lid within, for example, 50 mm. Moreover, the lower end 39 of each slotted latch 37 is made vertically above the lower end 40 of the guide latch 34, taking into account the height of the slotted cavity 3, which allows for faster and more reliable installation.

The vertical groove 13 and the horizontal axis 22 form a restrictive mechanism that prevents dangerous pressing of the lid clamping ends 30.

To ensure safety during the shift of the axis 18, it is possible to install a stop 41 fixed on a slider, the upper plane of which must coincide with the lower plane of the opening 21 of the slider.

The locking mechanism 7 of the position of the gripping levers is connected to the hook of the lifting and lowering device through, for example, its holder 42.

It is possible that there is a traverse in the gripping device when using, for example, heavy containers more than one, for example two, located mutually perpendicular to each other, structurally made similarly as described above.

The gripping device for the slotted lid of the container operates as follows.

The operation of the device is characterized by a four-cycle cycle: 1 and 1 (Figs. 4 and 5) - lowering the gripping mechanism for gripping and lifting the lid, 111 and 1U (Figs. 6 and 7) - lowering the lid and closing the lid of the container. At the same time, at each cycle cycle, the asterisk-ratchet 17 and the elements of the gripper occupy a strictly defined position.

The operation of lowering and lifting the lid, wiring of the gripping levers and rods, and the free passage of the guides 34 and the slotted 37 latches is carried out under visual inspection from two sides by the moulders.

The gripping device is hung on the hook 4 of the lifting and lowering device and in the opened position of the levers is lowered onto a container with a lid. At the same time, since the gripper is freely suspended on the hook, its position is manually adjusted by the molders.

Step 1. Lowering the gripper. The cycle of operation of the device begins with its lowering. At the initial moment, the gripping levers 28 and rods 26 are divorced and fixed with a ratchet asterisk 17, locked by a pusher 19 and the upper edge of the slider opening 21 in a horizontal position (Figure 4). Lowering of the gripping device is done before installing the traverse on the cover. At the moment when the traverse has not yet been mounted on the lid, the molders direct guiding latches 34 on the outer wall of the container due to the free hanging on the hook of the gripping device, while the beveled plane 35 of each retainer 34 slides along the edge of the wall, preventing its damage and chips, as well as speeds up their smooth installation. At the same time, slotted clamps are simultaneously installed in cavity 3 with some adjustment by the moulders due to the presence of 50 mm gaps for guide clamps 34 and 50 mm for slotted clamps 37. Thanks to the installation of slotted clamps, the clamping ends 30 quickly fall into the slotted cavities 3 and begin to abut against wall 32 of the container.

Step 11. Capturing and raising the cover, as well as holding it in a raised position. After installing the traverse with a stand on the surface of the lid, the hook of the gripping device continues to lower further, as a result of which the slider 16 moves, the pusher 19 of which pushes the ratchet sprocket 17, which, turning on the axis 18, occupies a vertical position, disengaging from holes 11 of the rack and 21 of the slider, and without interfering with the free movement of the gripping levers (Figure 5), which, under the influence of rods diverge with their upper ends, compressing the lower. Due to the presence of a longitudinal groove 31, the position of the endings 30, which abutted during the execution of Step 1 against the walls 32, is adjusted due to the fact that the gripping levers 28, having a degree of freedom to raise their axis 27 by the length of the longitudinal groove 31, exit the jamming position, then they capture the cover, squeezing it and holding it under further lifting under its own weight. To exclude the clamping cap, which is dangerous for the material of the cover, by its ends 30 and to prevent cracking in it, a limiting mechanism is provided in the device, which allows the further lowering of the slide to stop due to the horizontal axis 22 resting on the lower edge of the vertical groove 13 and thereby stop the compressive force of the wall gripping levers 28 covers.

When lifting the gripping device, the slider 16 moves freely upward, since the ratchet asterisk 17, when in a vertical position, does not interfere with the movement of the slide with rods 26 fixed on it with gripping levers 28. In this case, the lid is torn off the container and lifted upward by holding the grippers leverage under her own weight.

After capturing the lid, the container, if, for example, the gripping device is used on its packaging line, is diverted to fill its internal cavity with radioactive waste, and then returns under the gripping device to place the lid back to its original place.

Step 111. Lowering the lid into the container and releasing it from the grip. When lowering the gripping device with the cover with the lifting and lowering device, the moulders again direct it in such a way that the guides 34 and slotted latches 37 fall into their proper places, as described above, and the clamping ends 30 fall into the slot cavity 3. At the same time, the crosshead 6 again reaches the surface of the container, and the lid falls into the recess of the container in its original place. Further lowering of the slider leads to the fact that the pusher 19 presses on the ratchet sprocket 17, turning it (Fig.6), but not jamming. At the same time, the gripping arms are loosened. Moulders give a signal to raise the slider. The rods 26 divert gripping levers from the wall of the lid, lifting them up, and also removing the slotted and guiding latches. In this case, the clamping ends 30 are reinsured with a longitudinal groove 31.

1U beat. Lifting the gripper. The slider continues to rise, moving the pusher 19 out of engagement with the ratchet asterisk 17 (FIG. 7), and engages it with the lower edge of the edge of the slider opening 23, fixing the gripping arms in the raised position of the gripping device. Subsequently, the slotted cavity 3 on the packaging production line is filled with sealing material.

Next, the cycle is repeated when a new container with a lid is installed on the line. All operations with the gripper are made from the hand control panel of the molder.

If it becomes necessary to inspect the state of the device elements located inside the rack and the slider and repair them, a viewing window 14 and a window 25 are provided, which are compatible during inspection.

The ability to implement the container device is confirmed by the use of known means and non-deficient materials, including signs presented at the level of functional generalization, with the achievement of the technical result, which consists in increasing

reliability of capture of the slotted cover, due to the presence of additional gripping devices that take into account the design of the cover and its location, as well as to accelerate the capture process.
