Abstract

FIELD: transport.

SUBSTANCE: invention relates to transport vehicles for moving large-size products, in particular, radio-technical products. The cart is made as rectangular wheeled platform, stands installed vertically at platform corners. The platform has not less than eight mutually independent wheels mounted using swivel eccentric brackets with possibility to alternately lift each wheel over bottom of platform. When overcoming obstacles each wheel starting from front wheels is alternately lifted and lowered after obstacle has been overcome without touching the obstacle. When front and rear pair of wheels are lowered the platform horizontal position is provided by lifting or lowering individual wheels.

EFFECT: possibility is achieved to move large-size products over thresholds of door openings in rooms with floors of different heights while preserving horizontal position of cart platform.

Description

The invention relates to vehicles for moving large-sized products, in particular radio engineering products.

Known hand truck for the transport of goods containing a pair of wheels and a U-shaped frame, while forks are welded on the bottom of the U-shaped frame for swivel braces with the axle of the pair of wheels and with a strut and brace on an additional self-aligning wheel support, which is also a counterweight during installation rotation with the load in the vertical plane, while under the transshipment load the frame is equipped with a lodgement in the form of a bracket, giving the U-shaped frame an L-shape, and the hinged connection of the U-shaped frame braces and counter ensures that the U-shaped frame adjustment and quick unloading site podrazborku for transporting trolleys with lesser height dimensions (2312033, IPC 7 V62V 3/02, 2007.12.10).

The disadvantages of this trolley are its low carrying capacity and difficulty in overcoming indoor thresholds.

A trolley for transporting and docking blocks is also known, comprising wheels and a drive interacting with one pair of racks mounted on racks, pairwise crossed and articulated to one another, the wheels being pivotally mounted on the lower ends of the racks, and rollers mounted on their upper ends grooves around the circumference, pairs of racks are pivotally connected by longitudinal ties, the platform is made with two vertical bends in the form of segments mounted in grooves of the rollers with the possibility of movement, and on the other In addition to the racks, a second drive is installed, both drives being made in the form of jacks that move and slide the paired racks (No. 2273587, B62B 3/02, 2006.04.10).

The disadvantage of this trolley is the inability to ensure the horizontal position of the platform of the trolley when overcoming the thresholds of rooms or when moving in rooms with uneven floors.

The closest in technical essence is a transport trolley for transporting goods, made in the form of a rectangular platform on a wheeled drive, racks vertically mounted at the corners of the platform, equipped with additional racks installed on the platform two on each greater side, shelves with holes for mounting on racks in a predetermined position, which is determined by spacers inserted into the device, located between the shelves or between the platform and the lower shelf, and at least on one shelf The element for fixing the partition is pulled. At the transport cart, the racks are made telescopic, and each spacer is made in a cubic form with an opening for the rack and marked for a separate type of product, while the elements for fixing the partition are located on the shelf parallel to one of its sides, and the shelves themselves are made in different sizes - according to the size of the platform and reduced to half its length (No. 2189919, BVB 3/02, 2002.09.27).

The disadvantage of this trolley is the inability to ensure the horizontal position of the platform of the trolley when overcoming the thresholds of rooms or when moving in rooms with uneven floors.

The technical result of the invention is the ability to move large items by means of a trolley through the thresholds of doorways of rooms with uneven floors while ensuring the horizontal position of the trolley platform.

To achieve the technical result, a trolley is proposed, made in the form of a rectangular platform on a wheeled drive, racks vertically mounted at the corners of the platform, containing at least eight wheels independent from each other, secured by rotary eccentric brackets with the possibility of alternately lifting each wheel above the bottom of the platform .

Figure 1 shows the functional diagram of the trolley for transporting bulky products.

1 - trolley platform;

2 - trolley wheel;

3 - guard post;

4 - wheel lifting mechanism;

5 - transported product.

The trolley for transporting large-sized products contains a platform 1, to which are attached at least eight wheels 2 independent from each other via rotary eccentric brackets, racks 3 enclosing the product are placed at the corners of the platform, the wheels can be lifted using device 4. A transportable product 5 is mounted on the trolley .

Trolley for transporting bulky products operates as follows.

The transported product is placed on the platform 1, the racks 3 protect the product during transportation from accidental shock and damage. When the trolley approaches the threshold, the wheel raising mechanism 4 alternately raises the front wheels to a height above the threshold, then the trolley moves forward, the front wheels lower to the floor in the next room to the floor level of the neighboring room, then the second pair of wheels rises, etc. When lowering the front and the last pair of wheels on the floor of the adjacent room, the horizontal position of the trolley platform is set by the wheel lifting mechanisms.

Figure 2-5 shows the sequence of movement of the trolley for transporting bulky products from one room to another with uneven floors and moving across the threshold.

The design of the trolley allows for the transportation of large-sized products from room to room with floors of different levels, to overcome thresholds in rooms, ensuring the horizontal position of the transported product.

Claims (1)

A trolley for transporting large-sized products, made in the form of a rectangular platform on a wheeled drive, racks vertically mounted at the corners of the platform, characterized in that it contains at least eight wheels independent from each other, fixed by means of rotary eccentric brackets with the possibility of alternately lifting each wheel higher bottom of the platform, while overcoming an obstacle, each wheel, starting from the front, alternately rises and lowers after overcoming an obstacle without touching epyatstviya, and when lowering the front and rear pair of wheels raising or lowering of the individual wheels provided horizontal platform.
