Description

The utility model relates to the field of mechanical engineering, in particular to a lifting device / device mounted on a vehicle (small, medium and large motor vehicles).

A prior art autonomous truck loading / unloading system is known (DE 2811797, 09/27/1979). the truck inside is equipped with parallel guides along the entire length of the cargo space under the roof. The mobile shelf is supported on rails and has a lifting mechanism for lifting any loads. The elevator has a bracket at the end so that the elevator protrudes from the rear of the truck and lifts weights to and from the ground.

The disadvantage of this system is its complexity, which affects the operational characteristics and reduces the reliability of operation, also this system can only be installed in a buried van, which reduces its functionality and scope.

Known crane lifting apparatus containing a first frame with many beams, each of which has a duration, width, depth, and a second frame. The first frame is supported by the vehicle body. The second frame has a beam with a span, width and depth, and is made with the possibility of sliding along the first frame in a transverse orientation. The winch with the carriage is slideable on the second frame (US 7048491, 05.23.2006).

However, the aforementioned disadvantages are not resolved in this apparatus.

A device for a vehicle with a mounted lifting system is known, including a support frame mounted on a vehicle. A pair of sliding retractable parallel rails are mounted on a support frame. The front ends and the rear ends of the parallel rails can be connected. The crossbar, which supports the lifting mechanism with the possibility of sliding, is suspended from a pair of rails. The supporting frame can be collapsible mounted for transport. The support frame is mounted on the vehicle, at a height above the vehicle cabin or, alternatively, is included in the car racks (US 5743702, 04/28/1998). This source is selected as a prototype.

The disadvantage of this device is the design complexity and unreliability in operation.

The problem to which the proposed utility model is directed is to create a lifting device for installation on a vehicle (automobile transport), which would eliminate the above disadvantages.

The technical result achieved by the implementation of this utility model is to increase the operational performance / characteristics of the device by simplifying the design and installing on a rack (for example, arches or U-shaped) of a loading platform (on-board platform / body) or in a truck / transport van facilities.

The specified technical result is achieved in a lifting device for installation on a vehicle, containing two (parallel to each other) guide rails, each of which is made with a rail rotatable in a vertical plane, and a transverse two-support beam, made with the possibility of movement along the guide rails and rotary rails by support rollers mounted on a transverse double-beam, on which a lifting device is installed.

Guide rails and pivot rails may have a C-shaped cross section.

The swivel rail can be made with the possibility of folding for unobstructed closing of the awning or door of the vehicle body, and when unfolded, it ensures that the cargo is carried outside the vehicle body for the entire length of the rail track.

The lifting device may be a carriage or a trolley on which a winch with a hook is mounted.

The essence of the utility model is illustrated by drawings, where in FIG. 1 shows a general view of a lifting device with rotary rails spread out, mounted on U-shaped racks of a vehicle body; in FIG. 2 is a general view of a hoisting device with pivoting rails folded along body racks mounted on U-shaped racks of a vehicle body; in FIG. 3 is a side view of a lifting device; in FIG. 4 is a top view of a lifting device; in FIG. 5 is a view A of FIG. 3; in FIG. 6 is a section AA in FIG. four

The lifting device for installation on a vehicle 1 (automobile transport) consists of two C-shaped guide rails 2 installed on the top of a vehicle van 1 or on special U-shaped racks (elements) 10 and between which a transverse double support beam 4 is installed .

Each guide rail 2 is made with a rail 3 that rotates in a vertical plane (two folding sections of a C-shaped cross-section), each of which, when folded, allows you to freely close the awning or doors of the body 11 of the vehicle 1, and in the open state it provides the removal of the rail track, and therefore the load 9, outside the body 11 of the vehicle 1 for the entire length of the rail track (the length of the guide rail 2 and the rotary rail 3).

The rail (rotary section) 3 is fixed to the guide rail (fixed section) 2 with the help of an axis and a finger inserted into the eye of the working position. The rail 3 rotates about an axis fixed to the guide rail 2 after removing the finger 4 inserted in the eye. After rotation, the removed finger is inserted into the eye of the transport position, fixing the rail 3 at the required rotation angle.

The transverse (movable) two-support beam 4 is made with support rollers 5 that move the beam 4 along the rails 2 and 3, and a lifting device 6 is installed on it. The lifting device 6 is a carriage or trolley on which a winch 7 with a hook 8 is mounted.

Work description:

The driver moves to the required distance with the installed beam 4 in the retracted position and in the folded state of the rotary rails 3. After stopping, the rotary rails 3 are expanded, creating a section of the rail track along which the beam 4 with the lifting device 6 is carried outside the body 11 of the vehicle 1, so lifted by a winch 7 mounted on a lifting device 6, the load 9 can be moved outside the body 11 of the vehicle 1 for unloading or loading. After that, the beam 4 is moved inside the body 11 and the section of the rail track is folded (the rotary rails 3 are folded). After that, the vehicle 1 is ready for further movement.

Raising and lowering the winch hook can be with manual, electric, hydraulic or pneumatic drives.

The proposed solution has fewer parts compared to similar devices, due to the presence of a special form of rails in the extended position, the movable beam plays the role of a frame, which reduces the weight of the mechanism. Therefore, it is a more effective solution for the mechanization of lifting goods.
