Description

The invention relates to the field of shipbuilding and can be used for loading (unloading) of various cargoes on an underwater technical vehicle (PTS), including goods having a safety device and located in an uninhabited room located below the PTS waterline.

Known load-gripping devices (see the book under the editorship of II Artobolevsky “Mechanisms in modern technology”, volume 1, p.120 ... 123, M., Science, the main edition of the physical and mathematical literature, 1970), the main unit in which is a lever grip. When the device is lifted with cargo by the load bracket, the load is lifted automatically.

The disadvantage of these devices is their low operational reliability due to the automatic disclosure of the capture upon contact with the surface, as well as the large dimensions that make it difficult to load cargo into an uninhabited premises of the PTS. In addition, when loading and unloading goods with a safety device (see the album “Arms of Russia”, M., Publishing House “Military Parade”, 2000, p.105, for example hand grenade RGO and RGN, assault grenade RShG-1, RShG-2), these devices cannot safely lower (lift) goods into an uninhabited room located below the PTS waterline. Known automatic grips of lifting devices (see the book under the editorship of S. M. Melamed "Automatic captures for piece goods," M., Mechanical Engineering, 1965, p.24), in which the tick capture consists of two captures, pivotally mounted in the body of the rod, and spring-loaded levers. The capture of cargo in these devices is carried out automatically when the capture with the load is moving upward, and the cargo is opened when the load is lowered to the surface.

The disadvantage of these analogues is the large size, which complicates the operation of loading (unloading) of goods into an uninhabited room located below the PTS waterline. In addition, when loading (unloading) cargo with a safety device, additional difficulties arise in providing loading and unloading operations “blindly” into an uninhabited room located below the PTS waterline.

Known load gripping device comprising a housing with an eye (load bracket) for suspension to a load-lifting mechanism (see AS No. 852760, MKI B66C 1/42, bulletin No. 29 dated 08/08/81), a grip pivotally mounted on the housing in the form of spring-loaded gripping levers (hooks) and a vertically spring-loaded expansion wedge interacting with the shanks of the gripping levers, the expansion wedge is pivotally mounted on the housing by an axis and spring-loaded, and the wedge rotation limiter is fixed on the housing. Upon reaching the designated height when lifting the load, the grip automatically opens and the load is released from the device. This device is accepted by the applicant as the closest analogue.

Device by A.S. No. 852760, upon reaching a certain height, leads to the automatic opening of the gripper and the cargo is freed from the device, which is unsafe and does not allow handling of the cargo, which is especially unacceptable when loading (unloading) cargo having a safety device into an uninhabited room located below the PTS waterline.

The objective of the present invention is to ensure operational reliability, as well as expanding the operational capabilities of the device by providing loading (unloading) of cargo with a safety device in the absence of cargo visibility and its installation location (blindly) in an uninhabited room located below the PTS waterline.

The problem is solved due to the fact that in the known device for loading (unloading) cargo, comprising a housing with a cargo bracket for suspension to a lifting device at one end and with a grip, its body and spring-loaded hooks (levers) at the other end, according to the invention, the grip equipped with a stopper, which is installed by means of a casing on the capture housing with the possibility of rotation and interaction with the safety device provided on the load, and the device housing is made in the form of a hollow rod, on which it is possible In order to prevent rotation, a horizontal movable support is installed, as well as two fixed end stops and a guiding shell, while the gripper and stopper are equipped with actuators with a control unit, which are made in the form of a gripper and stopper rod, are installed in the hollow rod and are connected at the bottom with spring-loaded gripping hooks and with a casing with a stopper, respectively, and in the upper part - with a control unit, and the gripping rod is installed with the possibility of longitudinal movement, and the stopper rod is rotatable ota.

In addition, the gripping rod is installed inside the stopper rod and is made of interconnected upper rod with a gripper control handle, a transitional threaded rod, a main rod with a threaded tip and a lower rod with a handle for opening the gripping hooks mounted on it.

In addition, the guiding shell and the capture housing are fixed in the lower part of the device body, made in the form of a hollow rod, while the capture housing is fixed from a turn and is equipped with overlays between which the capture hooks are pivotally mounted on the axes of the capture hook, which are connected to the lower capture rod of the capture by means of earrings and preloaded by a spring mounted on the lower rod of the gripping rod, which has a stop for interacting with the stopper rod and limiting the stroke of the gripping rod, while the limiting straps are fixed on said overlays the possibility of interaction with the adjustment of the cargo, while in one of the limiting slats made a slot.

In addition, the stopper rod is made of interconnected couplings, the main shaft and the sleeve, on which a leash is mounted with the possibility of interaction with the casing, which is mounted on the gripper body with the possibility of rotation by means of a flange, while the stopper control handle is mounted on the coupling.

In addition, the stopper is made in the form of a sector, which is mounted on the casing, while on the sector a foot is made with the possibility of interaction with a safety device provided on the load.

In addition, the control unit is made in the form of a housing in which a stop clutch rod with an upper gripper rod installed in it is mounted with a possibility of rotation and fixing, and also a rack with the possibility of fixation with said clutch, while on the stop rod the stopper control handle is fixed to the horizontal plane, and the capture control handle is mounted in a vertical plane in the upper part of the said strut and the upper rod of the capture rod with the possibility of rotation, and in the upper part and a lock screw is installed in the clutch, and a U-shaped groove is made in the upper rod of the gripper rod to fix the gripper rod from vertical movement, while a ball lock is installed in the rack for fixing the clutch rod lock when turning to the extreme positions.

In addition, the horizontal movable support is equipped with a rotation lock device, which is made in the form of hinged spacers with spring-loaded latches, mounted to rotate in a vertical plane and interact with the receiving device of the underwater technical equipment on the axes mounted on the horizontal support, while the hinged spacers are made with the possibility of locking in vertical and horizontal positions using ball clamps and hooks, respectively.

The proposed technical solution of the loading and unloading device allows to improve the operational capabilities of the device due to the loading (unloading) of cargo with a safety device in the absence of visibility of the place of its installation (blindly) in an uninhabited room located below the PTS waterline, to increase the reliability of the device by introducing a stopper in its design, stopper rods and grips with a control unit for them, which allows to ensure a trouble-free transfer of the aforementioned cargo into working position, as well olyaet operator to simplify the operation to seize the cargo.

The device for loading (unloading) (see Fig. 1) contains a housing 1, designed for loading and unloading cargo 2 through a receiving device 3 into an uninhabited premises of the PTS through a crane 4. The device can be used for loading (unloading) of ordinary cargo, and cargo having a cargo trim 5 (see figure 2) and a safety device with a strap 6 to bring the load 2 into working condition (for example, preparing it for an explosion, see figures 2 and 3, see the album "Weapons of Russia", M., Military Parade Publishing House, 2000, p.105, for example, hand grenade RGO and RGN, assault grenade RShG-1, RShG-2), in a transport cup 7, which is also located in the uninhabited part of the housing 8 of the TCP below its water line 9.

The housing 1 is made in the form of a hollow rod 10. At the lower end of the housing 1, a gripper 11 and a stopper 12 are fixed (see Figs. 2, 3, 4, 5, 6, and 8), and a control unit 13 with a load bracket 14 is fixed at the upper end (see Fig.6 and 7). A horizontal movable support 15 is installed on the housing 1 (see FIG. 6), fixed from a horizontal turn by a key 16 (see FIGS. 6 and 16), and stops 17 and 18 are fixed, and a guide shell is fixed in the lower part of the housing 10 19.

The gripper 11 and the stopper 12 (see Figs. 12 and 13) are connected to the control unit 13 by means of a rod 20 and a rod 21, respectively, passing inside the hollow rod 10. The rod 20 is designed to interact with the hooks 22 of the gripper 11, and the rod 21 is for turning stopper 12, while the rod 20 is installed inside the rod 21. The rod 20 in the upper part is docked to the rod 23, and in the lower part by means of a threaded pair 24, 25 to the lower rod 26 (see Fig. 12, 13). The lower rod 26 is preloaded by the spring 27 and connected by the earrings 28 and the axis 29 to the handle 30 and the hooks 22. In the upper rod 23 (see Fig. 13) there is an axis 31 on which the handle 32 is held to control the grip 11. The rod 20 is designed to clamp-razgimy cargo adjustment 5 cargo 2 (see figure 2) by means of hooks 22 of the gripper 11 and it can move in the thrust (pipe) 21 only in the vertical direction.

The capture 11 and the stopper 12 (see Fig. 1, 2, 3, 4, 5, 6, 8, 10, 11 and 12) are used to capture the load 2 by the load trim 5 for loading and unloading, holding the load 2, locking safety bar 6 of cargo 2 and disconnection (undocking) of cargo fitting 5 of cargo 2 from UPVG.

The rod 21 of the stopper 12 along the entire length of the hollow rod 10 covers the rod 20 from the outside and, like the rod 20, is assembled from separate parts: in the area of the control unit 13 (see Fig. 13), the upper part of the rod 21 is made in the form of a sleeve 33, which is end-contacted in contact with a trunnion 34, which is rigidly connected directly to the pipe-rod 21, and in the area where the grip 11 is located (see Fig. 12), the rod 21 is rigidly connected to the tip 35, which is connected via a dowel 36 to the sleeve 37, on which the leash 38 is fixedly mounted for interaction I'm with a casing 39, on which the stopper 12 is fixed.

In the clutch 33, the handle 40 (see Fig. 13) for controlling the stopper 12 is fixedly mounted by imparting a rotational movement to the rod 21. The rod 21 is designed to rotate the casing 39 with the stopper 12 (see Figs. 2, 3, 4, 5, 10 and 11 ), which, interacting with the safety strip 6 of the safety device of the load 2 (see figure 2 and 3), leads, if necessary, to the working position of the load 2.

The grip 11 (see Fig.11 and 12) includes a housing 41 with pads 42 attached to it with fasteners. Between the plates 42, two hooks (gripping levers) 22 are pivotally mounted on the axis 29 through the earrings 28. The hooks 22 are pressed by a spring 27 mounted on the lower rod 26 of the rod 20. A stop 43 is installed in the upper part of the lower rod 26, which, when interacting with the shoulders of the tip 35 the traction of the stopper 21 limits the stroke of the traction 20 from the excessive opening of the hooks 22. The housing 41 is mounted on the housing 1, made in the form of a hollow rod 10. The gripper 11 is closed by a casing 39, which is mounted by means of a flange 44 and fasteners in the housing 41 with the possibility of rotation. The flange 44 consists of two parts, for ease of assembly, which are held assembled by the casing 39 by means of fasteners. The flange 44 is mounted rotatably in a groove made in the housing 41 of the gripper 11. On the plates 42 (see Fig. 11), the fastened curved plates 45 and 46 are attached for contact with the conical surfaces of the load adjustment 5 of the load 2, and in the plate 46 (see Fig. 2, 3, 4, 5, 11, and 12) a slot 47 is made for accommodating the legs 48 of the cargo fitting 5 therein for the purpose of orienting the cargo 2 relative to the transport cup 7 and fixing it from turning the rod 20 relative to the cargo fitting 5 of cargo 2. K the housing 41 of the capture 11 is fixedly mounted flange 49 with a guide shell 19, with tinned to guide the UPVG in the receiving device 3 during loading and unloading operations of cargo 2. An insert 50 is installed in the upper part of the lower rod 26, which enables the rod 21 of the stopper 12 to rotate around the lower rod 26 of the gripping rod 20 with the smallest frictional resistance forces. The capture 11 from a turn around its vertical axis is fixed through the insert 50 with a pin 51. The handle 30 is designed to carry out, if necessary, the operation of opening the hooks 22 (see Fig. 12) when the operator is on the pier. The earrings 28 are fixed at one end to the lower stem 26 and the other at the hooks 22 by means of the axles 52. The grip 11 is constantly in the “CLOSED” position by means of a spring 27 acting by the stem 26, the axles 52, the earrings 28 and the axes 29 on the hooks 22. The transfer of the gripper 11 to the “RELEASED” position is performed by the handle 30 or the handle 32 by turning down. The handle 32 is connected to the hooks 22 of the grab 11 by the thrust 20, and the handle 30 is mounted directly on the grab 11. The stop 12 (see Fig. 2, 3, 4, 5, 6, 10 and 11) is designed to turn and hold the safety strap 6 of the load 2 during loading and unloading, as well as for bringing cargo 2 into operational (explosive) condition, if necessary. The stopper 12 is a sector (see figure 10) with a foot 12, which is mounted on the outer wall of the casing 39 using fasteners. The rotation of the stopper 12 is possible due to the rotation of the handle 40 for controlling the stopper of the control unit 13 (see Fig. 13). The safety strip 6 of the load device 2 is pre-checked with a check 53 (see figure 3) to prevent unauthorized activation of the load 2.

The control unit 13 (see Fig.6, 7 and 13) is designed to actuate the gripper 11 and the stopper 12. The control unit 13 is made in the form of a housing 54, in which the coupling 33 of the rod 21 of the stopper 12, the upper rod 23 of the rod 20 of the capture 11, the stand 55, the grip control handle 32 and the stop control handle 40. The grip control handle 32 is fixed to the stand 55 by an axis 56 and is connected to the upper rod 23 of the rod 20 by the axis 31. The grip control handle 32 can rotate in vertical plane, and the stopper control handle 40 12 - rotational movement in the horizontal plane. In the rack 55 there is a ball retainer 57 for fixing the coupling 33 when turning it to the extreme positions. The handle 32 is designed to actuate the gripper 11 when the operator is on the PTS, in the area of the receiving device 3, and the handle 40 is used to rotate the casing 39 together with the stopper 12 when the operator is above the receiving device 3. The coupling 33 has two fixed positions: LOCKED ”, in which (see FIGS. 3 and 4) the safety bar 6 of load 2 is locked and rests against the stopper 12 (dashed line in FIG. 3), and“ FASTENED ”, in which the safety bar 6 of load 2 (see figure 5) is chiseled and abuts against the wall of the conveyor Nogo nozzle 7. The stops 58 (see. Figure 13) mounted on the housing 54, serve to limit rotation of handle 40 in the extreme positions. The handle 32 is used to bring the gripper 11 to the “CLOSED” and “RELEASED” positions, while duplicating the movement of the gripper handle 30 11. The cup-bearing 59 is installed in the housing 54 to facilitate rotation of the coupling 33, which is held by the fastener through the flange 60. In the upper part of the clutch 33, a locking screw 61 is mounted for fixing the rod 20 (see Fig. 13) through the upper rod 23 from moving it up and down and, accordingly, setting the gripper 11 to the “CLOSED” and “RELEASED” positions. To this end, a U-shaped groove 62 is made in the upper stem 23 (see Fig. 14), which prevents unauthorized opening of the hooks 22 when the arms 30 and 32 are in extreme positions.

The horizontal movable support 15 (see Fig. 1, 6, 15, 16 and 17) is designed to direct the movement of the rod 10 in the receiving device 3 of the TCP when performing loading and unloading operations using UPVG and orienting it in the horizontal plane (bow-feed) . The horizontal movable support 15 is made in the form of a housing 63 (see FIGS. 15 and 16), in which the hinged spacers 65 with latches 66, preloaded by springs 67 are movably fixed on the axles 64. The spacers 65 can be rotated on the axes 64 to disconnect the support 15 from the receiving device 3 when you press the stop 18 (see Fig.6) on the hooks 68 (see Fig.15) when moving UPVG with focus up. In the upright position (see FIG. 17), the spacers 65 are locked with a ball retainer 69. In the upright position, the spacers 65 are held by hooks 68 sitting on the axles 70 and supported by the spring stops 71. The horizontal movable support 15 is able to be fixed in the receiving device 3 by means of latches 66 that enter the corresponding holes 72 (see FIG. 1) in the receiving device 3. On the housing 63 (see FIG. 16) there is a threaded hole for installing the locking screw 73 therein for emergency stop or fixing the rod 10 when moving her up and down. To ensure reliable docking of the UPVG with the load 2 and prevent the turn of the load 2 relative to the transport cup 7, a key 74 is provided on the load 2, interacting with the corresponding groove 75 (see Figs. 3, 4 and 5) of the transport cup 7.

The load bracket 14 (see figures 1, 6 and 7) is designed to connect the UPVG with a crane 4 through loops 76 mounted on the housing of the control unit 13.

The stop 17 (see figures 1 and 6) is intended to limit the upward movement of the horizontal movable support 15 and the fencing of the handles 32 and 40 of the control unit 13 from grazing them during operation of the UPVG.

The guide shell 19 (see Figs. 1, 6, 8, 11 and 12) is designed to guide the UPVG when loading and unloading cargo 2 into the receiving device 3 and is held on the housing 1 (or 10) by means of a flange 49 (see Fig. 12 )

The operation of the UPVG for loading cargo 2, which is in an upright position on the base pier in a transport cup 7, located in an uninhabited room of the PTS case 8, located above the surface, is as follows (see figure 1).

The UPVG is fixed by means of a bracket 14 on the hook of the base crane 4. At the base pier, the UPVG is lowered onto the load 2 located vertically. Under the influence of the UPVG mass, the gripping case 41 (see Figs. 11 and 12) presses on the spring 27, the latter abuts against the shoulders of the lower rod 26 and through the earrings 28 acts on the upper parts of the hooks 22, which, turning about the axis 29, automatically open their hooked ends. At this moment, the UPVG contacts through the gripper 11 with the load adjustment 5 (see FIG. 2) of cargo 2. Further, when the UPVG is lifted, when its mass is received through the load bracket 14 by the crane 4, the hooks 22 are compressed by their spring 27 and horizontal hook-shaped ends go under the horizontal plane (see Fig. 12) of cargo fitting 5 (see Fig. 2) of cargo 2. Docking of UPVG with cargo 2 and capture of cargo 2 by capture 11 are made. Next, it is necessary to lock the safety strip 6 of the safety device of the load 2 (see figure 3, 4 and 5) from moving. To do this, on the pier turn the handle 40 of the control unit 13 against the direction of clockwise movement (see Fig. 9). In this case, the casing 39 (see Fig. 2, 3, 4, 5, 10 and 11) with the stopper 12 are turned in the same direction and the tab 12 contacts the safety bar 6, and at the same time, the locking rod 20 is locked (see 12 and 13) through the upper rod 23 with a groove 62 (see FIG. 14) of the control unit 13 by the locking screw 61 from moving up and down. Next, you need to strike the safety strip 6 (see figure 2, 3, 4 and 5) of the safety device of the load 2 in order to bring the load 2 in working condition. To do this, manually remove the pin 48 from the bar 6. On the pier, lift the UPVG with a load of 2 by a crane 4 and lower it into the receiving device 3 of the 8 PTS building. Next, the horizontal movable support 15 of the UPVG is docked with the receiving device 3 so that the spacers 65 of the horizontal movable support 15 enter the corresponding holes 72 (see Fig. 1) of the receiving device 3. Lower the UPVG with the load 2 into the transport cup 7 until it stops in its bottom . The safety bar 6 is unlocked by the handle 40 of the control unit 13 by turning the handle 40 in the clockwise direction (see FIGS. 3 and 9), the catch stopper 12 of the gripper 11 (see FIGS. 3 and 10 by the dash-dot line) has returned to its original position. By turning the knobs 30 or 32, the grip 11 is set to the “UNLOADED” position. Cargo 2 is disconnected from the UPVG. Using a lifting crane 4, the UPVG is lifted from the receiving device 3. When the stopper 18 (see Fig. 6) is pressed on the tabs of the hooks 68 of the horizontal movable support 15 (see Fig. 15), the latter rotate around the axes 70 and disengage the spacers 65, the latches 66 of the horizontal support 15 come out of the holes 72 (see Fig. 1) of the receiving device 3, the spacers 65 occupy a vertical position, which is fixed by the latches 69 (see Fig. 17).

Unloading cargo 2 from the transport glass 7 is carried out in the reverse order.

The UPVG 1 is fixed by means of the bracket 14 (see Fig. 1) on the hook of the base crane 4. Lower the UPVG 1 over the PTS body 8 onto the receiving device 3. The horizontal movable support of the UPVG 15 is joined with the receiving device 3 so that the horizontal movable struts 65 the supports 15 entered the corresponding holes 72 (see Fig. 1) of the receiving device 3. Lower the UPVG until the gripper 11 contacts the load adjustment 5 of the load 2. Under the influence of the UPVG mass, the housing 41 of the gripper 11 (see Figs. 11 and 12) presses spring 27, the latter abuts against the shoulders of the lower rod 26 and h cut earrings 28 acts on the upper part of hooks 22 which, turning about the axis 29, are diluted automatically their hook ends. Then they begin to raise the UPVG upward, its mass is perceived through the load bracket 14 by the crane 4, the hooks 22 are compressed by the action of the spring 27 and, under their horizontal hook-shaped ends, go under the horizontal planes (see Fig. 12) of the load hatch 5 (see Fig. 2) load 2 and capture of cargo 2 by capture 11 is made. The handle 32 sets the gripper 11 to the "CLOSED" position. Next, you must open the safety strip 6 of the safety device of the load 2 (see figure 3, 4 and 5). To do this, from the receiving device 3, turn the handle 40 of the control unit 13 in a clockwise direction (see Fig. 9). At the same time, the casing 39 (see Figs. 2, 3, 4, 5, 10 and 11) with the stopper 12 also rotate in the same direction and at the same time the locking rod 20 of the gripper 11 (see Figs. 12 and 13) is locked through the upper rod 23 with a groove 62 (see Fig. 14) of the control unit 13 with the locking screw 61 from moving up and down, which prevents unauthorized opening of the hooks 22. The stopper 12 has deployed the safety bar 6 of the load safety device 2 to its original state. When lifting the load 2 together with the UPVG hoisting crane 4, the stop 18 is pressed (see FIG. 6) on the tabs of the hooks 68 of the horizontal movable support 15 (see FIG. 15), the latter rotate around the axes 70 and disengage the spacers 65 from the mesh 66 of the horizontal movable support 15 emerge from the holes 72 (see FIG. 1) of the receiving device 3, and the spacers 65 occupy a vertical position, which is fixed by the latch 69 (see FIG. 17). Upon reaching the UPVG together with the load 2 of the height available for the operator, standing above the receiving device 3, manually check the pin 53 (see figure 3) in the safety bar 6 and thereby the load 2 is removed from the working position. Further, the UPVG together with the load 2 is transferred by a crane 4 to the base pier and lowered to its surface. In this case, the handle 30 is set to the position “UNLOADED”. Under the influence of the UPVG mass, the gripping case 41 (see Figs. 11 and 12) presses on the spring 27, the latter abuts against the shoulders of the lower rod 26 and through the earrings 28 acts on the upper parts of the hooks 22, which, turning about the axis 29, automatically open their hook-shaped ends and disengage from cargo fitting 5 of cargo 2. Cargo 2 is disconnected from the UPVG. With the help of a hoisting crane 4, the UPVG is diverted from the base pier to lift the next load 2 from an uninhabited room located below the PTS waterline.

The proposed technical solution allows for the loading and unloading of cargo with a safety device in the absence of visibility of the place of its installation (blindly) in the uninhabited premises of the PTS, which expands its operational capabilities, as well as increase the operational reliability of the device due to the introduction of a stopper, as well as stopper drives and capture with the control unit them, which also allows the operator to simplify the operation to capture cargo. In the proposed technical solution, the dimensions of the device (in width) are reduced, which do not exceed the dimensions of the transported cargo, which is especially important for limited premises of the TCP.
