Description

The utility model relates to the field of mechanical engineering, namely to loading and unloading devices, and can be used for transportation of cylindrical heavy containers with critical cargo (for example, explosive).

Currently, there are many devices for transporting barrels that can be used at any enterprises in conditions where there is a need to move goods over short distances (for example, for research purposes in laboratories, warehouses and bases, etc.) without using hoisting machines. However, having certain advantages, they cannot provide the required safety during transportation of predominantly heavy drums with explosives.

A known cart for transporting barrels [RF patent No. 2167076, IPC BV 3/06, publ. 05/20/2001 g] containing a frame, wheels, means for raising and lowering barrels. The frame of this trolley is made in a U-shape, two front wheels are rigidly fixed on their vertical axles, and the rear wheel is mounted with the possibility of rotation on the vertical axis. Two racks are rigidly connected to the frame, on which are mounted means for raising and lowering the barrel, including a crank with a drive handle, and means for gripping the barrel in the form of two plates connected to each other by a bridge. To prevent the barrel from falling out after its capture, a rod with a counterweight was used. The weight of the counterweight and its mounting location on the rod are selected in such a way as to balance the weight when the barrel is in the locked and raised position.

This trolley can transport cargo weighing more than 50 kgf without the use of complex lifting equipment (crane equipment, for example).

However, the drawback of this trolley is that the support frame of the U-shape is not sufficiently “rigid” and can be deformed during loading when transporting a heavy drum (for example, when moving along uneven ground) due to the influence of torque and bending moments. Moreover, in an unbalanced position due to the displacement of the center of gravity, the barrel can tilt to the side and, due to the small lifting height, catch on the floor surface and impede free transportation, which is ultimately unsafe when transporting heavy drums with critical cargo, including explosives .

Known hand truck for moving barrels and draining liquids from them, adopted as a prototype [RF patent No. 2375228, IPC VV 3/04, V 3V 3/10, publ. 12/10/2009 g] containing a frame, wheels, means for raising and lowering barrels.

The frame of the well-known trolley is made in a U-shape from rigidly interconnected horizontal and vertical tubular elements and four swivel wheels fixed to it. On the horizontal tubular frame elements, the first pair of support plates is rigidly fixed. The second pair of support plates is perpendicular to the support plates of the first pair, rigidly connected with the gap by means of corner scarves and has upper and lower vertical slots. A third pair of support plates is placed above the lower hoops of the barrel. The gripping device is made in the form of two flat plates, to the lateral ends of which in the upper and lower parts from the side of the rear wheels arcuate lodgements are rigidly attached, and from the side of the front wheels are flexible belts with coupling locks, in the center of which there are rotation axes. Means for lifting the barrel in the vertical plane is made in the form of a two-link mechanism, one ends of the first links of which are rigidly connected to the supporting plates of the third pair, and placed in the lower slots of the second pair of supporting plates with the possibility of vertical movement. And the other ends of the first links are rigidly connected to the second links with the formation of a right angle, the top of which is facing down and on which the movable roller is fixed, while the free ends of the second links are rigidly connected with the pressure pedal. The control unit of the gripping device is made in the form of a handle on which a lock of its position is fixed.

This trolley is designed to move containers, mainly metal barrels, and to drain liquids from them in warehouses and bases, that is, in conditions where there are no restrictions on height, angle of transportation and tipping.

The disadvantages of the prototype are:

- relatively low reliability in the case of transportation of cargo of large mass. To carry out the operation of draining the liquid from the barrel, the frame of the cart made of tubular elements is U-shaped, which in the case of transporting a cargo of large mass can lead to the possibility of deformation and divergence of the ends of the frame, which is unacceptable when transporting containers with critical cargo (for example, explosive substance);

- the complexity of the design. The presence of a lifting device in the form of two-link mechanisms, a control unit for the capture and rotation of the barrel significantly complicates the design of the cart;

- the design and large dimensions of the trolley reduce its mobility;

- besides this, the possible likelihood of the barrel overturning makes it impossible to use it for transporting containers with responsible cargo.

The objective of the claimed utility model is to create a simple mobile lifting device that provides safety and ease of operation during transportation of a heavy cylindrical container with critical cargo, such as explosives.

The technical result, which is achieved by the claimed utility model, is to ensure the reliability and safety of transportation of a heavy cylindrical container with responsible cargo while increasing mobility and simplicity of design.

The technical result is achieved in that the device for transporting a heavy cylindrical container containing a frame, wheels, means for lifting and lowering the container, according to a useful model, the frame is formed by two rolling platforms in the form of half rings, fastened by fasteners into a ring covering the transported container, from the outside to at least two L-shaped support brackets are rigidly attached to each half ring and, through radially arranged brackets, two support posts connected to the track s, each column represents a jack, serves as a means for raising and lowering the container.

The formation of the frame by two rolling platforms in the form of half rings fastened by fasteners into a ring covering the transported container, while at least two L-shaped support brackets are rigidly attached to each half ring and two support legs connected to the wheels through radially arranged brackets allow create a detachable, mobile structure with the simplicity of the design, and at the same time a “rigid” structure that centers the position of the load relative to the transport device ki, providing convenience and safety of operation of responsible cargo (explosive). In contrast to the prototype, where the device is complex structurally and contains a large number of nodes and parts interconnected with each other, requiring adjustment and adjustment during the manufacturing and assembly process, which is laborious to manufacture and therefore increases the cost of production, the claimed design is simple to execute and operate. In addition, the small dimensions of the lifting device make it possible to operate with a heavy container in cramped work conditions.

Each rack is a jack, which serves as a means for raising and lowering the container, which makes it easy and simple to adjust the height of the transported container, and in combination with jacks with wheels provides the lifting device sufficient mobility. At the same time, the strengths and stability, large lifting height, small dimensions, which allows the design to be compact, are among the advantages of jacks.

To make it possible to transport a large-sized container of large mass of the wheel to each jack can be installed in pairs.

In order to increase cross-country ability in case of movement on an uneven or dirt road, the wheels can be made free-wheeling, rubberized.

In order to increase the stability of the container when it moves along an inclined surface, the freely rotating wheels can be equipped with a wheel rotation lock, which allows the wheels to be fixed from a complete turn and to carry out a stable, safe movement.

Thus, the totality of all the above signs creates the conditions for creating a simple compact and mobile lifting device that ensures the safety of transportation of a heavy cylindrical container with responsible cargo (explosive).

The presence in the claimed utility model of features that distinguish it from the prototype, allows us to consider it appropriate to the condition of "novelty."

The utility model is illustrated by drawings.

in FIG. 1 shows a General view of the device with the transported container;

in FIG. 2 - shows a General view of the device, a top view;

in FIG. 3 is a section AA in FIG. 2, the design of one half ring with L-shaped brackets;

in FIG. 4 is a section BB in FIG. 2, the design of the jack stand with wheels;

in FIG. 5 shows an embodiment of the use of the device when loading a container, for example, into a cargo gate of a helicopter. The device is as follows.

A device for transporting a heavy cylindrical container 1 (Fig. 1-4) contains a frame formed by two rolling platforms in the form of half rings 2, fastened by fasteners 3 into a ring covering the transported container 1. For this, plates 4 s are welded to the ends of each half ring 2 coaxial holes 5, into which fasteners are inserted 3. Each half-ring 2 is made of a bent channel with a radius corresponding to the diameter of the cylindrical container 1. On the inner surface of the half-rings 2 are attached on a rubber gasket 6. At least two L-shaped support brackets 7 and two radially located brackets 8 with jack racks 9 are rigidly attached outside the generatrix of each half-ring 2. Each L-shaped bracket 7 with a vertical shelf is rigidly attached to the half-ring 2 in such a way that the horizontal shelf is directed towards the center of the ring - the frame. In turn, the jacks 9 are connected to the wheels 10 through a T-shaped support 11, which is fastened to the axis of rotation 12 of the wheels 10.

A device for transporting a heavy cylindrical container is used as follows.

For transportation of a large-sized container of large mass, the wheels 10 are installed in pairs to each jack 9. And in order to increase the cross-country ability to move the load-lifting device along the dirt road, the wheels 10 are freely rotating, rubberized. These wheels 10 are able to freely rotate around the axis 13 of the jack and be fixed from a complete rotation in a certain position using the locking device 14.

Both platforms are rolled up to the vertically standing cylindrical container 1 from the sides, covering the container 1 with half rings 2 and leading the free shelves of L-shaped brackets 7 under the bottom of the container 1 (barrel) (or the bottom stop flange available at the barrel 1). Then, the half rings 2 are fastened by means of fasteners 3 into a ring around the container 1, reliably fixing it in the device. Using racks-jacks 9 carry out the lifting and transportation of the "raised" container 1 to a given place of unloading. Using jacks 9 by rotation of the handles 15 make it possible to control the height of the transported container 1.

Subsequently, when moving along an inclined surface, for example, along ramps 16 to air transport (airplane or helicopter) (Fig. 5), the freely rotating wheels 10 are fixed from full rotation by means of a locking device 14, made, for example, in the form of a spring-loaded rod 17, which injected into one of the holes 11 made in the T-shaped support 11.

The compactness and small dimensions of the proposed lifting device allow you to use it, for example, when passing a large bulky container 1 through the cargo hatch 19 of the helicopter with a minimum clearance height (Fig. 5).

This device can also be used in other industries where such barrels are used, in which there is a stiffener on the bottom made in the form of an annular protrusion.

The company tested the device for transporting large-sized heavy drums. The test results confirm the simplicity, reliability and safety of transportation without the use of crane equipment. The inventive device made it possible to carry out loading and unloading of heavy drums with critical cargo when passing the cargo hatch of the MI-8 helicopter with a minimum clearance height.
