Description

The invention relates to vehicles used for the transportation and storage of goods, in particular high-quality coal.

A device for transporting containers [a.s. SU No. 1311985, IPC В62В 1/06, В60Р 1/64, B66F / 06, publ. 05/23/1994], containing four trolleys, which are mounted on the side of the side panels of the container for lifting and installing the container on the vehicle platform, and when transporting containers by towing them with a tractor using a towing device, on the side of the container end panels. Each rolling trolley consists of a rack connected to the wheels and equipped with a rack-and-pinion lifting mechanism with a ratchet device and means of attachment to the container. In order to increase operational capabilities, the rack is made with two grooves, in which the support and the rod are placed with the possibility of vertical movement, made in the form of rails associated with ratchet dogs, located in the housing formed by the intermediate part of the rack. Moreover, the shanks of each dog are equipped with spring-loaded plungers associated with the traverse associated with the handle. Moreover, these wheels are attached to the jacks, which are pivotally connected to the rack rod.

The main disadvantage of this technical solution is the low reliability, which complicates the movement of the container on soft soils.

As the closest analogue, a vehicle was selected for transporting and storing goods [US No. 1693700 A, 04/04/1928] containing a container, two composite frames fixed to the side walls of the container, and screws on which wheel hubs are mounted and can be moved and which equipped with ratchet gears with drive handles.

A disadvantage of the known technical solution is the low reliability of the device.

The objective of the invention is the provision of maneuverability and movement of the container and the reliable design of the claimed vehicle.

The problem is solved in that in a vehicle for transporting and storing goods containing a container, two composite frames are mounted on the side walls of the container, and screws on which the wheel hubs are movably mounted and which are equipped with ratchet mechanisms with drive handles, according to the claimed technical To the solution, the container is made with uprights installed at the corners of its bottom, each frame consists of an upper threaded sleeve and a lower guide rail, in which for moving the slide, a slider is installed with a bracket on which the lower support sleeve is fixed, while in the middle on the outer surface of the wall of the lower support sleeve there is a shaft on which the wheel hub, which is removable, is mounted for rotation, in the upper threaded and lower the support sleeves are respectively mounted with the possibility of vertical movement and rotation in the horizontal plane of the first and second screws, the first screw being kinematically connected in the middle stvom first gearbox to a drive shaft rotatably mounted under the bottom of the container and is kinematically connected via a second gear unit with the second screw.

Due to the fact that the first and second composite frames are installed on the side walls of the container at the same distance relative to its bottom, high throughput and maneuverability of moving the container is ensured by installing or removing removable wheels of larger diameter on the shafts of the lower supporting bushes of the corresponding composite frames.

Due to the fact that in the upper threaded and lower support bushings of the first and second composite frames, coaxially arranged relative to each other, respectively, the first and second screws equipped with ratchet mechanisms with drive handles are installed with the possibility of vertical movement and rotation in a horizontal plane, which reduces labor costs and time to install or remove the removable wheels.

The invention is illustrated by drawings.

In FIG. 1 shows a vehicle for transporting and storing goods in a transport position, side view; in FIG. 2 is a view of FIG. 1 along section AA.

A vehicle for transporting and storing goods comprises two first and second composite frames fixed to the container.

As seen in FIG. 1, racks 1 and a support are mounted on the container bottom opposite each other and equipped with a shaft on which the wheel 2 is mounted for rotation. On the side walls 3 of the container, the first and second composite frames are installed at the same distance from its bottom.

Each of the composite frames consists of an upper threaded 4 support sleeve and a lower guide bar 5, in which a slider 6 with a bracket 7 is mounted with the possibility of vertical movement. A lower 8 support sleeve is fixed to the bracket 7. Moreover, in the middle on the outer surface of the side wall of the lower 8 of the supporting sleeve, a shaft 9 is made, on which the hub 10 of the removable wheel 11 is mounted for rotation.

As seen in FIG. 2, in the upper threaded 4 and lower 8 support bushings of the first composite frame, coaxially arranged relative to each other, the first 12 screw is mounted with the possibility of vertical movement and rotation in a horizontal plane.

In the upper threaded 4 and lower 8 support bushings of the second composite frame, coaxially located relative to each other, a second screw is installed with the possibility of vertical movement and rotation in the horizontal plane (not shown in Fig. 2).

Moreover, the upper threaded 4 support sleeve of the first composite frame is made with a right internal thread that engages with a mating thread made on the upper parts of the first screw, and the upper threaded 4 support sleeve of the second composite frame is made with a left internal thread that engages with a mating thread made on top of the second screw. The smooth lower parts of the respective screws are inserted into the lower 8 support bushings of the respective composite frames. In order for the first 12 and second screws to move vertically together with the lower 8 support bushes of the respective composite frames, the first and second screws are provided with two retaining rings 13 (see Fig. 2).

The first 12 and second screws are provided with a first 14 and a second (not shown in FIG. 2) ratchet mechanisms. The first 14 and second ratchet mechanisms are equipped with the first 15 and second (not shown in Fig. 2) drive handles.

As seen in FIG. 2, the first 12 screw of the first composite frame is kinematically connected by means of the first 16 gearbox to a drive shaft 17 rotatably mounted under the bottom of the container and kinematically connected by means of the second gearbox to the second screw of the second composite frame (not shown).

Each of the gearboxes consists of a drive gear 18 mounted on the lower end of the corresponding screws, and a driven gear 19 mounted on one of the ends of the drive shaft 17.

Adjustable lift works as follows.

In the initial position, when the container is stably supported by the uprights 1 and the wheel 2 on the vehicle platform or on the ground, and the lower 8 support bushings of the first and second composite frames mounted on the side walls 3 of the container are located at a distance greater than the diameter of the removable wheel 11, on the shafts 9 install or remove the removable wheels 11.

Then, to translate the container into the transport position, clockwise rotation of the first 15 drive handle of the first 14 ratchet mechanism causes the first 12 screw to rotate in a horizontal plane. The clockwise rotation of the first 12 screws by the drive gear 18 of the first gearbox 16 is transmitted to the drive shaft 17. By rotating counterclockwise, the drive shaft 17 rotates the second screw counterclockwise in the second composite frame.

Rotating synchronously in different directions, the first and second screws together with the lower 8 support bushes of the respective composite frames are moved downward in a vertical plane along the lower guide bars 5 by means of sliders 6. As a result, the shafts 9 are installed at a distance equal to the diameter of the removable wheels 11, and the container is driven in the transport position in which the racks 1 of the container are at a distance that ensures its movement. In this position, the container by means of the wheel 2 and the removable wheels 11 moves on the surface of the earth. Moreover, the presence of the wheel 2 provides stability of movement of the container.

To transfer the container from the transport to its original position, counterclockwise rotation of the first 15 drive handle of the first 14 ratchet mechanism rotates the first 12 screw in a horizontal plane. The counterclockwise rotation of the first 12 screws by the drive gear 18 of the first 16 gearbox is transmitted to the drive shaft 17. By rotating clockwise, the drive shaft 17 rotates the second screw clockwise in the second composite frame.

Rotating synchronously in different directions, the first and second screws together with the lower 8 support bushes of the respective composite frames are moved upward in the vertical plane along the lower guide bars 5 by means of sliders 6. In this case, the container posts 1 are lowered down in the vertical plane. As a result, the shafts 9 are installed at a distance greater than the diameter of the removable wheels 11, and the container is brought to its original position.
