Description

(54) LOADING MACHINE

one

The invention relates to building hoisting mechanisms, in particular to load lifting devices.

A load-lifting device is known, which comprises a running carriage mounted on inclined track guides with a load gripping element associated with a drive winch, the rope of which is stocked through the upper and lower outflow blocks mounted on the structure.

However, this lifting device cannot handle the loading and unloading and horizontal movement of cargo between the means of transport and the warehouse or building.

The purpose of the invention is to expand the technological capabilities of the device without increasing the number of drives,

To achieve the goal, the winch is mounted on a undercarriage equipped with a turntable with a rigidly fixed stand on it, at the end of which a guide block is mounted, and a support

a column with a boom equipped with a block, as well as a limiter installed at the top of the rack, through which the cargo rope runs around the horizontal block, the rope being made with a hook hook.

FIG. 1 shows the device during loading and unloading; in fig. 2 - the same, when the cargo is delivered to the building side; in fig. 3 - the same, top view.

Claims (2)

The lifting device contains a wheeled trolley 2 with a rotary platform 3, a drive winch 4 mounted on it, with a drive winch 4 with a hoisting cable 8 with stock through fastened 1e to the building 5, and a hook cable 8 8, and lO mounted on the swiveling platform 3, the support kolsdana 11, the boom 12 with the block 13 and the limiter 14 of movement of the load rope 8 with the crane hook 15, the rack 16c with the forward unit 17. The console 18 is suspended on the rack 16 on which the pc is rigidly fixed vomited 19, a brake (not shown) and operator workstation 20, Placing on the turntable 3. The apparatus operates as follows. To perform loading and unloading operations, the wheeled trolley 2 is installed and braked at the end of the guide track 1 opposite the vehicle 21. The lifting and lowering of the load 22 engaged with the crane hook 15 is performed after the winch 4 is turned on by moving the rope 8 through the blocks 6, 7, 13 and 17. The horizontal movement of the load 22 between the vehicle 21 and the warehouse or building 5 is exerted by turning the boom 12 with the supporting column C, mounted on the rotating platform 3, and moving the wheel carriage 2 along the guide Uchi 1. Rotating platform 3 performs a one- Rhatore finds schiys workplace 2O via handwheel 19 that the Executive zuet Operator for this purpose as a fixed bearing for the lever force applied to them. Moving wheel bogie 2 Ive on an inclined path 1, i.e. in the direction of building 5, the fixed movement of one end of the rope to the drum of the working winch 4 is fixed, and the reverse movement is performed when winding the rope 8 and due to the slope of the guide path 1. The loading and unloading operations in the warehouse area located along the inclined path 1 with a braked wheeled cart 2. Vertical supply of cargo 22 to the openings of building 5 is carried out with the wheel trolley 2 braked near the building 5, with the end of the rope 8 fixed from moving by the limiter 14. When winch 4 is turned on, the detachable joint 9 and 10 is lowered to wind up. When winch is on 4, the operator disconnects the rope 8, retracts the block 7, which is pivotally attached to the building 5. When the winch 4 is turned on, by moving the rope 8 with the hook 9, the load 22 is lifted to the openings of the building 5. neither. In order to carry out a continuous transport-overload cycle, the preload 22 from the vehicle 21 is rotated by the boom 12 fixed on the platform 3, is moved and lowered onto the trolley 2 from the placement side of the winch 4, the trolley 2 is moved towards the building 5 and the cargo 22 is hooked from the crane hook 15 on hook 9. If necessary, operations are performed in reverse order. The present invention has an improved winch efficiency compared to known devices. Claims of the Invention A lifting device comprising a chassis trolley mounted on inclined track guides with a load gripping element associated with a drive winch, the rope of which is stored through the upper and lower diverting blocks mounted on a structure, characterized in that opportunities without increasing the number of drives, the winch is mounted on a undercarriage equipped with turntables mine with a rack rigidly fixed on it, at the end of which a direction is set The supporting unit, and the supporting column with the boom equipped with the unit, as well as the limiter installed in the upper part of the rack, through which the load contact passed, the horizontal unit, and the said rope is made with a hook-hook connector.
