FIELD OF THE INVENTION The invention relates to the field of industrial transport, in particular to picking edges and stackers for warehousing.

Pick-up stacker stackers are known, which contain a vertical column with a movably fixed pa pay by a load carrying capacity carrying an installed operator's cab in the guides.

A disadvantage of the known stacker cranes is a poor view of the working area, since when the cab is displaced relative to the forklift, the installation level of the container with the cargo rises above the cab floor.

The purpose of the invention is to improve the design of the stacker crane, i.e., increase the view of the working area and the height of the service.

This is achieved by the fact that on the rear wall of the cabin a single end of a pivoting single arm is reinforced, the second end of which is curved and has two rollers. One roller is located in the bend of the lever, and the second is directly at its end. The forklift is equipped with a sloping projection, HOSLT, acting on the first roller, and the column in the upper part is made with a notch, which serves to fix the second roller.

FIG. 1 shows a picking stacker, general view; in fig. 2 - the same view

from the side; in fig. 3 - a forklift with a cabin in the extreme upper and middle positions; in fig. 4 shows a section along A-A in FIG. 3

The picking stacker crane contains a vertical column 1 mounted on a frame 2 having two running wheels 3 and 4. On the column 1 a forklift 5 is movably mounted, moving along the pipe with the help of

rope drive 6 lift. The forklift has a frame 7, formed by four rollers 8, which roll along the guides 9 of the column, keeping the lifting capacity horizontally. On the frame of the forklift there are cargo telescopic grips 10 and 11, which serve to pack the tared goods in the racks, and in the frame window there is an operator's cab 12 equipped with a seat 13 and control panels 14.

A bracket 15 is attached to the rear steppe of the cab 12, one of which is pivotally attached to one end of the pivoting single-arm lever 16, the second end of which is curved and has two rollers 17 and 18. The roller 17 is located in the bend of the lever 16, and the roller 18 is at its end. In the frame of the forklift between the column and the cabin there is a jumper 19, bounded above by an inclined projection 20, acting on the roller 17 and forming with

vertical plane angle a.

In the upper part of the column there is a recess 21 serving to fix the roller 18 and formed by the lower plane 22, wall 23 and the upper plane 24. The plane 22 serves as a support for roller 18 and should have a slope allowing the lever 16 to rotate. For this, the tangent of angle ai, formed by plane 22 and vertical wall 23, should be less than the ratio of the vertical distance a from the axis of the hinge of the lever 16 to the axis of the roller 18 to the horizontal distance b from the axis of the hinge to the axis of the roller 18, t . e.

. To the rear wall of the operator's cabin b

guide bars 25 are attached on both sides, along which four rollers 26 mounted on a forklift frame are rolled.

Pick crane stacker works as follows.

The load placed in the container is fed by means of electric floor trucks or by a conveyor to the working area of the stacker crane to the loading device. The operator of one of the grippers takes the goods and sets it in the rack. When the lift actuator 6 is turned on, the forklift lifts, which rests against the upper plane 24 on the roller 17. The lever cannot turn because the roller 18 is locked with a column. There is a simultaneous lifting of the forklift with the operator's cab. At the same time, the cabin is positioned relatively high to the grippers 10 and 11, and it is convenient for the operator, after the crane stacker stops at the rear cell, to install the pallet with a load using a telescopic gripper and perform other operations.

In the case of a load of goods to the upper ranks of the rack, the lever 16 under the action of the horizontal component of the reaction of the roller 17 at its contact with the inclined protrusion 20

turns and goes out into recess 21. The weight of the cab is transmitted through the lever to the roller 18 resting on the bottom plane 22, the cab stops and the forklift continues to lift. Cab lever is provided

locked up from turning up

with jumper 19 upwards, the cabin maintains its

position thanks to roller 26 which

cut by guide channel 25.

When lowering the forklift jumper

19 releases the roller 17 of the lever 16, and the latter, under the action of the horizontal component of the reaction of the roller 18, at its contact with the inclined plane 22, rotates and exits the recess. The weight of the cab is now transferred to the forklift and the cab is lowered with it.

Subject invention

A pick-up stacker crane, containing a vertical column with a movable forklift mounted on it, carrying an operator cab installed in guides, characterized in that, in order to improve the design of the stacker crane by increasing the view of the working area and the height of the service, one is fixed on the rear wall of the cab the end of the pivoting one-arm lever, the second end of which is made curved and has two rollers,

one of which is located in the bend of the lever, and the second is directly at its end, the forklift being provided with an inclined projection acting on the first roller, and the column in the upper part is made with a notch serving to fix the second roller.
