the lowering table, made in the form of two, not connected to each other, bar- lok 4, located along the cart. The frame 1 is provided with stops 5 with rollers, mating with the end surfaces of the beams 4. On the frame 1 at the ends: The control arms of the control device for the trolley driving mechanisms, made in the form of a three-link hinge consisting of end 6, are articulated. , intermediate 7 and support 8 links. The end link 6 has a shank 9 with a T7-shaped groove, 10 that mates with the hinge 11 of the end and intermediate links, and is provided with rollers 12 and 13.

The intermediate link 7 has a shank, 14, connected with him by the hinge 15.

In the lower part, the pin 14 has a groove L6 AND mates with an 8-mm supporting link. In the upper part, intermediate link 7 has lateral protrusions 17 and 18 of tubular shape located in the plane of the hinge 19 of the intermediate and supporting links.

The support link 8 has stops 20 and 21 in the lower part, while its hinge 22 is provided with a return mechanism, made in the form of torsion springs 23, and is associated with cams 24, each having projections 25 and 26. The stop 27 is mounted on frame 1.

- The transfer trolley is equipped with limit switches 28-37 for controlling the nature of movement and the pumping station. Beams 4 are fitted with stops 38 that interact with limit switches 28-31. The switch switches 32-35 interact with the cams 24 of the control levers. The end switches 36 and 37 cooperate with the end stops 39 installed at the end loading and unloading positions. The cams 24 are placed in pairs in the zone of the support link 8 of each control knob, and the protrusions 25 on each of them are placed so that when the lever is rotated clockwise, the support link 8 interacts with one cam through the protrusion 25, and when turned counterclockwise, with the other cam 24 through the same protrusion. 25, the protrusions 26 of one cam are placed on opposite sides of the support 27 for engagement with the latter.

The cart in the front part has a control panel 40, on the panel of which are located the switch 41 of the type of operation Loading - Unloading, the loading and unloading voltage switch 42, buttons 43 and 44 respectively moving the cart to the left and right, button 45 Stop, Lift button, button 47 Lowering cargo platform.

The transfer trolley is mounted on the rail track 48 between the rails 49 of the storage rack, which are supports for the load.

The operation of the trolley and its control device is as follows.

Depending on the direction of loading (on the right or left side of the warehouse), a switch 42 is installed. Button 43 or 44 is pressed depending on the direction of movement of the cart, after which the pumping station is driven and the hydraulic cylinders 3 are raised. which raise 4 along with the freight package

the shank 9 of the end link 6 is removed from the cavity of the protrusion 18 by moving its groove 10 relative to the hinge 9 until it stops into it, then rotates, the end link 6 at the joint 11 and the shank 9 is inserted into the cavity of the protrusion 17 of the intermediate star by 7, then the switch 41 is set to the unload position.

Depending on the direction of unloading (on the right or on the left side of the warehouse), a switch 42 is set, a button 43 or 44 is pressed depending on the direction of the switch

over the guides 49. When the beams 4 reach the extreme position, the stops 38 act on the limit switches 28 and 30, the movement actuator 2 is turned on, and the pumping station is turned off, after which the cart with the lifting freight package moves in a predetermined direction.

When the cart reaches a predetermined position or a previously laid load package, the control lever is rotated clockwise relative to the hinge 22 and one of the cams 24

5 acts on limit switch 33 or 34 depending on the direction of movement. The drive 2 is turned off, and the pump station is turned on and the hydraulic cylinders 3 are lowered,

When the beams 4 reach the lowest position, the stops 38 act on the limit switches 29 and 31, after which the drive of the pumping station is turned off, the drive 2 of the movement is turned on and the carriage returns to its original position. Upon reaching

0, the limit stop switch 39 or the limit switch 36 triggers and the actuator 2 is turned off.

Unloading from the warehouse. The cart is at the end position with the beams 4 lowered, the control levers when unloading from the left side of the warehouse are set to the position shown in FIG. 7, and when unloading from the right side to the position shown in figure 9,

The NIN rises the intermediate link 7 from the support link 8 relative to the hinge 19 and turns downwards relative to the hinge 15 and is laid on

the shank 9 of the end link 6 is removed from the cavity of the protrusion 18 by moving its groove 10 relative to the hinge 9 until it stops into it, then rotates, the end link 6 at the joint 11 and the shank 9 is inserted into the cavity of the protrusion 17 of the intermediate star by 7, then the switch 41 is set to the unload position.

Depending on the direction of unloading (on the right or on the left side of the warehouse), a switch 42 is installed, a button 43 or 44 is pressed depending on the direction of movement of the carriage, after which the Drive 2 moves and the carriage moves in a predetermined direction from 1 beams 4. The cart passes; it lies under the cargo rack lying on the guides 49 and rests against the rear control lever, while the beams 4 are under the freight package. The control lever is turned relative to the hinge 22 and the cam 24 acts on the limit switch 32 or 35 depending on the direction of movement.

I Drive 2 is turned off, {the pump station drive is turned on and hydraulic cylinders 3 are lifted, Beams 4 are lifted with a freight package over rails 49. When beams 4 reach the extreme upper position, the stops 38 act on the end switches ™ gels 28 and 30, the pump station turns off and the drive 2 is turned on and the tee moves in the given direction of the contribution. When the cart reaches the koi ™ end stop 39, the limit switch 38 or -37 is triggered, the actuator 2 is lowered and the hydraulic cylinders 3 are lowered, Beams 4 with a load package Lower and the last sets - from to the rails 49 When reaching (end 4)

The pores 38 affect the end switches |: the switches 29 and 31 j, after which the nature of the pumping station turns off.

To transport the carriage to the final position under the lying cargo packages on the steering 49 of the warehouse, the control levers are placed in the position shown in FIG. 11. For cJToro, intermediate links 7 lift from support links 8, turn down relative to hinge 22 and lay on the frame 1o Beams 4 find | mc in the lowered position. Press the button 43 or 44 depending on the desired direction of movement, switch-on 2, after which the cart moves in a given direction. When the car reaches the end stop 39, the limit switch 36 AND is activated; 37 and the actuator 2 is turned off,

Thus, the described control device allows the transfer chute to carry out the following technical & nical operations: loading from the right or left side of the warehouse, transfer from the left or right side of the warehouse to the right or left side to unload cargo The trolley travels to the final positions under the load lying on the storage rails.
