Description

The utility model relates to the field of military equipment, namely, to mobile carriers of ammunition for multi-barreled weapons, and can be used to load a launcher (PU) of a combat vehicle of a multiple launch rocket system (BM MLRS).

Known equipment for loading a launcher with rockets of a transport-loading machine (TZM) (RU, patent No. 18300 for a useful model "Transport-loading machine" according to z. No. 2000131101 from 13.08.2000, IPC F41A9 / 35, F41A9 / 87), containing a hydraulic crane-manipulator, a mechanism for loading the launcher with rockets with a load gripper and cable guides, a hydraulic manipulator control system and a remote control panel for the manipulator.

As a prototype, a crane-manipulator of a transport-loading machine was chosen for loading the launcher with rockets (RU, patent No. 27202 for a useful model "Transport-loading machine" under z. No. 2002115971 from 17.06.2002, IPC F41A9 / 35, F41A9 / 87 ), which contains a movable column mounted on a fixed base with the possibility of turning, a boom with an extension and a hydraulic manipulator control system with a hydraulic cylinder for rotating the movable column and hydraulic cylinders for lifting and bending the boom. The extension is movably fixed at the end of the boom and allows it to be bent. The hydraulic control system of the manipulator contains a hydraulic cylinder for turning the movable column and hydraulic cylinders for lifting and bending the boom. The hydraulic drive and the manipulator are controlled by an external remote control.

The disadvantages of both the prototype and the above-mentioned analogue include the fact that the process of vertical movement of the load is carried out by two working bodies of the manipulator - a hydraulic cylinder for lifting the boom and a hydraulic cylinder for boom bending, which reduces the accuracy of moving the load and, accordingly, increases the time of the loading process. In addition, the operation of these hydraulic cylinders is controlled from the control panel by different buttons, i.e. the work of the hydraulic cylinders is carried out sequentially, which also leads to an increase in the time of the loading process.

These disadvantages reduce the efficiency of the loading process.

The technical result of the utility model is to increase the efficiency of the loading process.

The technical result is achieved in that the crane manipulator of the transport and loading machine (TZM), containing, a movable column installed in a stationary body on the stern of the machine with the possibility of turning, an extension boom, which is movably fixed at the end of the boom to ensure its bending, and a hydraulic control system for a crane-manipulator, including a hydraulic cylinder for turning the movable column and hydraulic cylinders for lifting and bending the boom, made with control from a remote control panel, according to the utility model, contains a load lifting mechanism located in the boom extension body and containing a hydraulic cylinder for lifting a load, a carriage, a pulley block, including movable and fixed blocks, and a lifting cable with a hook suspension fixed at its end, while the carriage is connected to the rod of the hydraulic cylinder for lifting the load and is movably installed in the body of the extension by means of guides, and in the upper part of the extension there are holes for squares for working fluid water to the specified hydraulic cylinder.

In this case, the crane-manipulator is made with the possibility of installation on the TPM, made on the basis of a wheeled chassis.

In this case, the crane-manipulator is made with the possibility of installation on the TPM, made on the chassis of the base tank.

The analysis of the distinctive features showed the following:

the presence of a load lifting mechanism expands the possibilities for moving the working organs of the manipulator, accelerates the loading process, which increases the efficiency of the loading process;

the implementation of the load lifting mechanism in the form of a hydraulic cylinder for lifting a load, a carriage and a chain hoist, including movable and stationary blocks and a lifting cable with a hook suspension fixed at its end, is the most optimal design of a load lifting mechanism that ensures the achievement of the specified technical result;

the implementation of the carriage connected with the rod of the hydraulic cylinder for lifting the load, and its installation in the body of the extension is movable by means of guides and the implementation in the upper part of the extension of the holes for the squares of the working fluid supply to the specified hydraulic cylinder ensures the operability of the mechanism for lifting the load, ensuring the achievement of the specified technical result.

The manipulator crane (hereinafter referred to as the crane) TZM is designed to transfer the captured projectile to the loading mechanism in the process of loading the BM MLRS launcher.

The crane 1 is installed in a fixed body 2 on the stern of the machine 3 (Figs. 1, 7, 8) with the possibility of turning and contains a movable column 4, a boom 5 with an extension 6, which is movably fixed at the end of the boom 5 to ensure its bending, and a hydraulic loader crane control system. The hydraulic control system includes a hydraulic cylinder 7 for turning the movable column 4, a hydraulic cylinder 8 for lifting the boom 5 and a hydraulic cylinder 9 for bending the boom 5.

The boom 5 of the crane and the extension 6 are a box-shaped welded steel structure.

To reduce the time of the loading process, a load lifting mechanism has been introduced (Figs. 2, 3, 4). The specified mechanism is located in the body of the extension 6 of the boom 5 and contains a hydraulic cylinder 10 for lifting the load, a carriage 11, a pulley block, including movable and stationary blocks, respectively 12 and 13, and a lifting cable 14 with a hook suspension 15 fixed at its end (Fig. 5). The carriage 11 is connected to the rod of the hydraulic cylinder 10 for lifting the load and is installed in the body of the extension 6 movably by means of guides (not shown in the figure). In the upper part of the extension 6, holes 16 are made for the hydraulic elbows 17 for supplying the working fluid to the hydraulic cylinder 10.

The crane is controlled by a remote control panel 18 (Fig. 6) from a place convenient for the operator. Control from the console 18 is carried out by turning on the following toggle switches: toggle switch 19 to turn on the operation of lifting and lowering the load, toggle switch 20 to turn on the pumping station, toggle switch 21 to turn on the power, toggle switch 22 to turn on the operation to raise and lower the extension 6, toggle switch 23 to turn on the operation of lifting and lowering the boom.

In the transport position, the crane 1 is fixed to the TZM body by the bracket 24 (Fig. 7).

The crane is made with the possibility of its installation on the TPM, made both on the basis of a wheeled chassis and on the chassis of a base tank. FIG. 7 shows the placement of the crane in the transport position on a TPM on a wheeled chassis. FIG. 8 shows the crane in working position on a TPM on a tank chassis. The stowage of shells on the TPM is covered with protective covers 25.

Work

When loading the launcher TZM and BM MLRS (Fig. 8) are installed at the required distance.

When the crane is operating, the boom 5 with the extension 6 is removed from the bracket 24 by controlling the hydraulic cylinder 8 from the toggle switch 23 of the console 18 and is moved to the side above the left protective casing 25 by the hydraulic cylinder 7 for turning the column 4.

With the help of a crane, the left and right casings 25 are dismantled by pressing the toggle switch 19 to turn on the operation of lifting and lowering the load. In this case, the hydraulic fluid through the square 17 (Fig. 2) enters the hydraulic cylinder 10 for lifting the load, extends the rod of the hydraulic cylinder 10, moving forward the carriage 11 with movable blocks 12. The tension of the branches of the lifting cable 14 of the pulley decreases, and the hook suspension 15 is lowered down. The presence of a load lifting mechanism alternating operation of hydraulic cylinders 8 and 9 when lowering the boom 5 of the crane to dismantle the protective covers 25.

Then on the hook suspension 15 is hung a lifting sling (not shown in the figure), the second end of which is installed in the lifting loops 26 of the protective covers 25 (Fig. 7). By moving the toggle switch 19 (Fig. 6) to the "UP" position, the rod of the hydraulic cylinder 10 returns to its original position, increasing the distance between the movable and fixed blocks 12 and 13 (Fig. 3). In this case, the hook suspension 15 with protective covers 25 moves vertically upward until it leaves the working area. Then, turning the column 4 by the hydraulic cylinder of rotation 7 (Figs. 1, 7), the manipulator crane takes the protective covers 25 to the side and places them on the ground.

Further, to carry out the process of loading into the brackets (not shown) of the launcher 27 (PU) of the BM MLRS 28, the loading mechanism 29 is installed (Fig. 8). The loading mechanism 29 is designed to capture the projectile and orient its axis with the axis of the PU pipe and feed it into the PU pipe and is made in the form of a system of racks, supports and a guide and a load-gripping device.

By controlling the hydraulic cylinders 7, 8, 9, the crane-manipulator is moved to the shells 30 and it is installed above the latter. The hook suspension 15 is lowered, a load-gripping device 31 (Fig. 8) of the loading mechanism 29 is installed on it, which, with the projectile 30, rises vertically upward, is removed from the working area and moves, and is placed on the guide of the loading mechanism and, by the grip of the loading mechanism, is sent to the pipe PU 27 ...

Then the crane with a load gripper 31 is transferred to the next projectile. By rearranging the guide and supports of the loading mechanism, the remaining pipes of the PU BM are loaded.
