And when using threaded fasteners in the design, it is possible to install different axle mounting brackets that allow the wheels to be pushed back, thereby freeing the frontal plane for installing bulky goods.

Description

The universal lifting trolley refers to the means of transporting liquids in standard cans with a capacity of 25 l and 38 l, as well as liquefied propane gas in cylinders with a capacity of 27 l and 50 l for short distances. If necessary, the trolley can be equipped with a removable body, which allows bulk materials and small piece loads to be transported, and when using threaded fasteners in the design, it is possible to install different axle mounting brackets that allow the wheels to be pushed back, thereby freeing the frontal plane for installing bulky loads.

The purpose of the invention is to improve the operational characteristics of existing manual wheeled means of transportation and increase the convenience of using cans with a capacity of 25 l and 38 l, gas cylinders of 27 l and 50 l in domestic conditions, in beekeeping, agriculture, and production.

The level of technology.

The closest analogue of the utility model is: Hand truck of the USSR 1736800 A2 05/30/1992

The design of this trolley contains: a horizontal axis with wheels rigidly connected to the drawbar; hook for hanging the flask; handles made in the form of a pipe segment, perpendicularly welded to the drawbar, allowing them to be gripped by hands to transport the cart; a bracket for fixing the flask on the trolley, made in the form of a cylindrical part of the flask; supporting platforms welded on the ends of the bracket, made in the form of hooks having the ability to engage with the U-shaped bevels of a quick-detachable scraper; a separate socket in which bolts are screwed to lock the detents of the swap body.

This design allows transporting a 38 liter can and technical flasks, bulk or piece goods in a mounted body. The design drawback is that the can is grabbed by one handle and the entire load is transferred to it during transportation. If there are bumps on the road, the can handle made of cast silumin can break off.

The second drawback is the drawbar design made of only one vertical stand with a pipe section welded at its upper end, forming handles. For transportation, you need to twist your hands behind your back, or drive the cart with only one hand, which is possible only if there is a solid, very smooth surface of the asphalt surface or poured concrete floors in the warehouse. Moving cargo on it on rough dirt roads in rural areas is becoming very difficult.

The third drawback: the design does not have the ability to transport a gas cylinder with a capacity of 50 liters.

The essence of the utility model.

The universal manual lifting trolley contains a chassis made in the form of an axis 4 with wheels 5, two vertical posts I forming a drawbar, in the lower part of which two pieces of a rectangular profile pipe 15 are welded with round holes in the middle for installation of an axis 4 in them, in the upper part of the drawbar it has handles of a curved shape 6 for gripping by hands during transportation, in the middle between the vertical racks there is a crossbeam 2 with a removable hook 7 for gripping and pulling when the trolley tilts the can onto itself onto the lower support ru 3 welded to vertical racks and equipped with a removable tool tray 8 for fixing the can during transportation.

Vertical posts 1, transverse crossbeam 2 (or two transverse crossbars upper and lower), lower support 3, axis 4 form a rigid metal frame whose components are joined together by welding or connected using a combination of threaded fasteners with rivets and U-shaped brackets installed inside profile tubes (used as transverse crossbars) from both ends. Mounted elements are installed on the rigid frame, depending on the need to transport this or that cargo. To transport the cans, hook 7 and the lower lodgement 8 are installed, for transporting a gas cylinder with a capacity of 50 l, it is necessary to remove the hook 7 and install a wooden lodgement 16 with the thumbscrews 12. To transport a gas cylinder with a capacity of 27 l, it is necessary to install a lodgement 17 and fix it with bolts and lamb 12. For the transport of bulk materials, it is necessary to install a removable body 18, having previously removed the hook 7 and all installed lodgements from the frame.

The universal rigging trolley is designed to facilitate the transportation of milk cans with a capacity of 25 l and 38 l in rural (country) areas, when in view of the lack of water supply, they are used to transport drinking water from a well to a house along a bumpy dirt road, so the trolley has two parallel handles for grip with both hands. At the same time, the hands of a person carrying this trolley remain in a natural position along the body, and not turned out behind the back, as is the case with the prototype.

In addition, the trolley can transport gas cylinders with a capacity of 27 l and 50 l, for which quickly installed lodgements and fixing rubber tows are used, which rigidly fix the cylinder on the trolley. If it is necessary to transport bulk materials: such as sand, gravel, gravel or small piece items: such as brick, paving slabs, cobblestone or cement in bags, a hinged body is used.

Depending on the type of wheels installed, on the condition of the road and the physical data of a person, this trolley allows you to carry goods weighing from 40 kg (can with water) to 150 kg (wet sand).

The carcass frame is a welded or collapsible structure of two vertical and three (or four) horizontal stiffeners, on which all other elements are installed. The vertical posts forming the drawbar are made of a profile tube with a cross section of 20 × 40 mm (20 × 50 mm; 25 × 50 mm), the middle rung has a cross section of 40 × 40 mm or 25 × 4 mm (40 × 50 mm or 25 × 50 mm ), and in the case of using a design with four horizontal stiffeners, both transverse crossbars are made of a profile pipe with a cross section of 25 × 40 mm or 20 × 40 mm (20 × 50 mm or 25 × 50 mm). The lower support is made from a corner with a section of 70 × 70 mm (63 × 63 mm) or from a corner bent at right angles from a strip of sheet metal. The axis is made of a bar with a diameter of 20 mm (16 mm), at both ends it has a thread of 20 × 1.5 mm (16 × 1.5 mm) for fastening the wheels. Vertical racks on top have handles made of a bent pipe with a section of 1/2 inch or a curved bar with a diameter of 20 mm, on which rubber handles are put on. Also, to improve the manufacturability of the product, the handles can be injection-molded in molds and have a rectangular parallelepiped at their base for installation in existing cavities of the upper ends of the uprights. At the bottom of the vertical posts are welded, or screwed with screws and nuts, or mounted on rivets lengths of 14-20 cm, made of a rectangular profile pipe of the same section as the vertical posts or wider, which allows you to move the axis slightly further from the frame . These segments have through holes with a diameter of 20 mm (16 mm) through which the axis is mounted, and in the case of fixing the axis with a bracket, there are no through holes in the side walls of this segment.

When transporting the can, the main advantage of this design is that its entire mass is transferred to the lower support, and the hook is used only to grab the can at the time of pulling on the lower support. During transportation, the hook only supports the can, preventing it from tipping over, and the lodgement made of two corners screwed to the lower support prevents the can (or gas cylinder) from rolling from side to side.

The design of the hooks provides for their different lengths. For a can with a capacity of 25 l, the hook is slightly longer, and for a can with a capacity of 38 l it is slightly shorter in view of the significant difference in the height level of the cans themselves. In addition, the hooks can be attached to the frame either through round holes that provide it with a strictly specified position, or through elongated holes that allow you to adjust its lifting height, which makes it possible to fine-tune the height of the can handle. Which, in turn, depends on the accuracy of fixing the lower support hoop of the can, which can be welded with an error of several millimeters and thereby significantly complicate the subsequent transportation of cans using this trolley.

As the initial structural material, a steel profile pipe with a thickness of 1.5-2 mm, a corner with a thickness of 4-5 mm, a steel bar with a diameter of 16-20 mm and a round floor inch pipe are used.

With the whole simplification of the design and giving it a more aesthetic appearance, you can use the aluminum profile: a profile pipe with a thickness of 2-3 mm, a corner with a thickness of 4-5 mm, a duralumin rod with a diameter of 20 mm.

When using rivets or threaded connectors to connect the components of the carcass frame, we get the opportunity to produce a set of components (essentially an adult constructor) from which the product is assembled on site, whether in the home workshop or assembly takes place directly behind the counter in the store by the seller in the presence of the buyer. In addition, transportation and storage of an unassembled product always takes up less space than an assembled structure, which has a significantly larger volume.

When using a collapsible circuit i.e. the use of threaded attachment of the chassis to the frame, we get the opportunity to change the lower brackets securing the axis. Thus, installing brackets of different heights made of a corner or of segments of a rectangular profile pipe, we move the axis a greater distance from the frame. Which in turn pushes the wheels from the front of the frame on which the load is installed. This makes it possible to install (and therefore transport) bulky goods, the installation of which was not possible due to the protruding wheels forward. Such goods can include large-sized household appliances packed in cardboard boxes.

To give the most aesthetic appearance and to prevent moisture from getting inside the profile tubes used in this design, rectangular and round plastic end caps are used that are installed on the upper and lower ends of the vertical posts and on the axle mounting brackets made of pieces of a rectangular profile pipe. Also, round-shaped plugs are installed on the underside of handles made of segments of a round pipe.

Information confirming the possibility of implementing a utility model.

The lifting truck of FIG. 1, FIG. 2, FIG. 3 has two vertical racks 1 forming a drawbar, a transverse crossbeam 2, a lower support for transported goods 5 made of a corner, an axle 4, two wheels 5, handles 6 with rubber handles 14 on, removable screams 7. lower lodgement for can 8, two lock nuts 9, two fixing nuts 10, bolts 12 with flaps for fixing the hook and the upper lodgement, mounting brackets made in the form of two pieces of a rectangular profile pipe 15 with holes for fixing the axis 4. In addition to the above poses The product can be equipped with a lodgement 16 for transporting a gas cylinder with a capacity of 50 l, and a lodgement 17 for transporting a household gas cylinder with a capacity of 27 l, a body 18 for bulk materials and small obese objects.

To transport the can with a capacity of 38 l, it is necessary: to install a can of one of the handles to the trolley, the trolley must be tilted to the can at an angle that allows you to hook 7 on the can handle, with both hands grasping the handles of the cart with one foot against the 4 axis and pulling the handles on yourself. in this way, pulling the can on the lower support 3 and in the middle of the cradle 8. After loading the can on the cart, turn your back to it (alternately grabbing the handles of the cart 6), grasp the rubber handles of the handles and carry the cart behind you. If the transportation distance is small, then you can not change the position of the body relative to the trolley and roll it in front of you.

To carry out the transportation of the can with a capacity of 25 l, it is necessary to install a longer hook of Fig. 11, Fig. 12 and rearrange the lower lodgement 8 closer to the center, thus setting a smaller distance under the smaller diameter of the can.

To transport a gas cylinder with a capacity of 50 l, it is necessary to install a lodgement 16 on the crossbar 2 with screws and flaps 12. Having installed the cylinder, it is necessary to secure it with rubber bands with hooks at the ends, hooking them to the vertical posts 1 (Fig. 4, Fig. 2. 5).

To transport a gas cylinder with a capacity of 27 l (Fig.6), a lodgement 17 must be installed. It is fastened with screws and thumbs 12 to the vertical racks I. Having installed the cylinder on the trolley, it must be fixed with a rubber luggage band to prevent it from falling.

For the transport of bulk materials or small piece items, it is necessary to install a removable body 18 (Fig.7). To do this, remove the hook 7 and the lower lodgement 8. Then fix the body with two screws to the lower support 3 and two screws to the crossbeam 2. After these simple manipulations, the trolley is ready to use it as a garden or construction one.

To increase the strength of the carriage frame (Fig. 8), an additional (second) transverse crossbeam 2 between the vertical posts 1 can be installed.

To reduce the assembly time of the trolley, handles made by the injection method of Fig. 9, Fig. 17, Fig. 18, mounted directly in the cavity of the vertical struts, can be used. Also inside these cavities can be mounted handles made of a curved duralumin wire of Fig. 13, Fig. 14 with the installation end of Fig. 15 sharpened on both sides. Which is installed (Fig. 16) in the cavity of the vertical struts I using two inserts 2 and fixed with screws and nuts through the existing through holes 3.

In Fig.19, Fig.20, Fig.21 shows the possibility of using screw connections for assembling the cart. In this case, the construction of the rigid frame is welded from two vertical posts, one or two transverse crossbars and a lower support for the transported goods (having the shape of a corner). But it is also possible to fasten the lower support with screws and nuts, which allows you to install different supports for different loads. The chassis (axle with wheels) is mounted on removable brackets with different heights. The brackets are attached to the uprights using bolts and nuts, and the axis having a thread on both sides is installed using two pairs of nuts.

In Fig.22 and Fig.23 shows the possibility of using as a mounting bracket a piece of a rectangular profile pipe 2 with an insert 4 (made of plastic or wood) clogged into the internal cavity. The axis 1 is fastened with two brackets 13, screwed to the mounting brackets with two screws 3 included in the insert 4 installed in the cavity of the bracket. The axis itself is additionally fixed with two screws 10 passing through the brackets 13, which prevents it from moving to the right and left and possible turning inside staples. Using threaded fasteners 5, the mounting bracket 2 is fastened to the vertical posts 6, to which the lower support for the transported goods 8 is also attached with screws 7 from the opposite side. Wheel 9 is mounted on the axle 1 using a lock nut 11 that determines the depth of its fit on the axis and the fixing nut 12 determining the rigidity of the wheel mounting, and the possibility of spontaneous unscrewing of the nut 12 prevents the cotter pin 15. To facilitate the fastening of the bracket 2 to the upright posts 6 using threads x 5 is applied fasteners line 14 with nuts mounted thereon, that allows for the rapid threaded connection bolts and nuts inside the shaped tube.

On Fig shows the possibility of shifting the axle with the wheels mounted back using interchangeable mounting brackets, which allows you to install and transport large loads on the trolley, how many wheels are now outside the plane defined by the front sides of the vertical

racks. The higher the bracket, the larger wheel diameter can be installed.

On Fig and Fig.26 shows the possibility of mounting the transverse crossbeams 2 to the vertical posts 1 with rivets 4 (or screw connections) by installing in the inner cavity of the transverse crossbar U-shaped bracket 3. The location of the two end fasteners can be on the outside vertical rack 1 (Fig.25), in this case, to improve the fastening plate 5 is used. If the fastening of the end of the transverse beam to the vertical rack is carried out for one wide wall, which allows you to remove sticking from the external thoron racks elements inside (Figure 26), then the Socket installation of fasteners through the holes 6.
