Description

The invention relates to loading devices, namely to devices for loading a transport and launch container (TLC) into a vertical launcher (VLU), for example, a ship, and can be used for lifting, tilting and loading into a TLU combined into a block (package) of a multi-seat TPK using universal lifting equipment.

Known suspended tilter according to copyright certificate SU No. 796151 (B66C 1/10, 1981). The known device contains a traverse, to which a frame is suspended with a drive mechanism mounted in it, which transmits synchronous rotation through a system of gears to drums, on which movable slings are wound. At the ends of the traverse, brackets are installed symmetrically perpendicular to its longitudinal axis, in which deflecting blocks are mounted in pairs on each side, interacting with the carrier blocks through movable slings. These blocks are installed in the groove of the traverse, one on each side parallel to its longitudinal axis. At the ends of the traverse, a number of holes are made for rearranging the brackets with blocks when changing the dimensions of the canted load. Slings of constant length are fixed into the holes adjacent to the bracket. The brackets on the traverse are pivotally fixed with the help of semi-axes.

However, said suspended tilter does not involve tilting long loads along the transverse axis. The presence of a bulky traverse makes it difficult to operate the specified hanging tilter.

A suspension tilter is known according to the RF patent for the invention RU No. 2531640 (В66С 1/00, B66F 19/00, 2014), hung on a crane hook, consisting of a housing with internal teeth, the lower middle part of which has a cutout for the output of an endless chain, hung on the gear shaft sprocket. Said sprocket is connected through bearings to two carriers having a counterweight or a spring mechanism, which are pressed onto an axle having end journals for brake pulleys, mounted on flanges having platforms for brakes, which are bolted to the housing with internal teeth. Lugs, legs and a ring gear are also welded to the body, and a stop is fixed on the ring gear with the help of a latch, which regulates the height of the gear shaft lifting along the body with internal teeth to control the length of the gear shaft rolling path and, thereby, the angle of rotation of the product, while the brakes have a two-speed hydraulic pusher motor.

A disadvantage of the known device is that for tilting products of great length, it is necessary to have two overhead cranes or one crane with two trolleys.

The closest in terms of essential features to the claimed invention is the cargo suspension of equipment according to the RF patent for the invention RU No. 2502664 (B66C 1/00, 2013). The device contains at least one sling associated with the load-bearing element and with the equipment. At least one sling is connected to the load-carrying element through a hinged mechanism having mutually movable bearing parts provided with a rotary mechanism, the first element of which is rigidly fixed on the first bearing part of the hinged mechanism, and the second element is rigidly fixed on the second bearing part of the hinged mechanism. The first bearing part of the articulated mechanism is intended for connection with the load-carrying element, and the second bearing part of the articulated mechanism is intended for connection with the sling and includes at least two pulleys zigzagly covered by the sling, mounted on the second bearing part of the articulated mechanism, and an insert located between them, part of the contour of which in the section perpendicular to the axes of the pulleys is made in the form of an arc. One pulley is installed coaxially with the second element of the rotary mechanism.

The disadvantage of the known device is the impossibility of tilting the product from a horizontal to a vertical position, the lack of adaptation to different weight and size parameters of products.

The problem solved by the invention is to create a reliable and simple unified device that allows safe tilting of a multi-seat or single TPK of various sizes during their transfer to the loading site, having minimal weight and size characteristics and ease of operation.

This problem is solved by the fact that in the device for tilting and loading a multi-seat TPK in the TLU, containing the tilter housing, an eye is fixed in the upper part of which, and a chain block is fixed in the lower part, through which a chain is thrown, the ends of which are fixed on the traverses, while the specified chain the unit is connected to the electric motor by means of a multi-stage gearbox. Said traverse includes a beam fixed on a load-bearing frame made in the form of a collapsible structure by means of quick-release fasteners. Said beam is fixed on the power frame by means of articulated rods, providing free rotation of the transport-launch container.

The technical result is the adaptability of the device for tilting and loading a multi-seat TPK into a TLU for various types of TPK, providing the possibility of tilting from a horizontal position to a vertical position and vice versa, reducing the cycle time of loading a TPK, due to the possibility of tilting during its movement to the place of loading.

The invention is illustrated by drawings. In FIG. 1 - general view of the device; in fig. 2 - view of the tilter; in fig. 3 - kinematic diagram of the tilter; in fig. 4 - view A in Fig. 1 (view of the traverse from the side of the TPK cover), where a is a multi-seat TPK, b is a single TPK; in fig. 5 - view B in Fig. 4, a.

The device for tilting and loading a multi-seat TPK in the TLU contains a tilter body 1 in the upper part of which an eye 2 is fixed to interact with the hook of the lifting device on (not shown in the drawing) and a power cable 3, and a chain block 4 is fixed in the lower part, through which the chain is thrown 5. The ends of the chain 5 are fixed on the traverse 6, with the possibility of interaction with the TPK 7.

The chain block 4 of the body of the tilter 1 is connected to the electric motor 8 by means of a multi-stage gearbox 9. The transmission of torque from the electric motor 8 to the gearbox 9 is carried out through the limit torque clutch 10, which is structurally combined with the locking electromagnetic brake 11 mounted on the high-speed shaft 12. To create a braking torque is used axial force of the worm gear 13 of the gearbox 9, which is created by the gravity of the load being lifted. The low-speed shaft 14 of the gearbox 9 interacts with the chain block 4 through the clutch 15.

Traverse 6 includes a beam 16 with a bracket 17 mounted for movement along the beam 16 and interacting with 13 holes 18 using locking fingers (not shown).

The number of holes 18 is due to all possible cases when the center of mass of the TPK 7 is displaced relative to the center (various options for loading the TPK 7). The beam 16 is fixed on the load-bearing frame 19 with the help of rods 20 pivotally rotating in the horizontal plane with the ability to move apart in the longitudinal axis. The power frame 19 serves to fix the TPK 7 and is made in the form of a collapsible rectangular structure, including a removable jumper 21, mounted on the power frame 19 by means of quick-release fasteners 22. The rod 20 has a position lock 23 that interacts with the support 24 mounted on the power frame nineteen.

The device works as follows. TPK 7 is delivered and stored in a known manner at the place of work, which is equipped with a crane (hereinafter referred to as the crane). Then the device, using eyelet 2, is fixed on the crane, the power cable 3 is connected to a voltage source and moved over the TPK 7. The traverses 6 are fixed at the attachment points located at the ends of the TPK 7, for which the power frame 19 is moved apart and placed at the attachment point. After that, the jumper 21 and fasteners 22 fix the power frame 19 on the TPK 7. Further, depending on the load of the TPK 7, the bracket 17 is moved along the beam 16 and installed in one of the possible places, fixing the beam 16 with fixing fingers and holes 18. Then, with a crane raise the body of the tilter 1, which leads to the tension of the chain 5 and the rotation of the rods 20.

For transportation of TPK 7, the device with TPK 7 fixed on it is lifted by a crane and moved to the loading site. At the same time, a signal is sent through the power cable 3 to the electromagnetic brake 11 and the electric motor 8. In this case, the electromagnetic brake pads 11 are unclenched and the engine starts to rotate. Through the torque limit clutch 10, mounted on the high-speed shaft 12, the torque from the electric motor 8 is transmitted to the multi-stage gearbox 9. The low-speed shaft 14 of the gearbox 9 drives the chain block 4 through the clutch 15, which interacts with the chain 5. Rotating, the chain block 4 moves the chain 5 by engaging the chain links 5 with the teeth of the chain block 4, while one end of the chain 5 (left in Fig. 1) rises to the body of the tilter 1, and the other is lowered, transferring the TPK 7 from a horizontal to a vertical position. In this case, the rods 20 of the traverse 6 rotate: the left one (in Fig. 1) is transferred to a vertical position, and the right one (in Fig. 1) is fixed, providing a predetermined position of the rod 20 at a safe angle relative to the TPK 7. Fixation of the rod 20 is carried out by stopping the latch position 23 on the support 24. When the TPK 7 reaches the vertical position, the electric motor 8 is turned off, and the electromagnetic brake 11 fixes the high-speed shaft 12, while the right branch (in Fig. 1) of the circuit 5 becomes free (not loaded). To avoid uncontrolled movement of the chain block 4, a worm gear 13 is installed in the gearbox 9 on the high-speed shaft 12.

At the end of the tilting process, TPK 7 is hung at a predetermined height above the opening of the loading cell of the launcher coaxially with the latter. Then the lower traverse 6 is removed from the TPK 7 by removing the jumper 21 from the fasteners 22 and expanding the power frame 19. Having freed the lower end of the TPK 7 from the traverse 6, the TPK 7 is lowered into the opening of the cell until it contacts the thrust pad of the launcher, after which the upper traverse 6 is disconnected from TPK 7 in the above way and the device moves to the next TPK.

Unloading TPK 7 from the launcher cell is carried out in reverse order.

In the version of the traverse 6 for a single TPK 7, the beam 16 does not have holes 18, and the bracket 17 is fixed non-separable.

Thus, due to the peculiarities of the device for tilting and loading a multi-seat TPK into the TLU, the invention provides adaptability to various types of TPK, providing the possibility of safe tilting from a horizontal position to a vertical one and vice versa. At the same time, the invention reduces the cycle time of loading the TPK into the TLU due to tilting during the movement of the TPK to the place of loading. In addition, the invention provides ease of operation, has minimal weight and size characteristics and high reliability. The above allows you to expand the operational capabilities of the set of devices for loading the transport-launch container into the vertical launcher of the ship.
