Abstract

The invention tends to handle the handling and storage equipment, in particular, storage facilities. The aim of the invention is to increase reliability. In the device rails, in the initial positions of the rear wheels of the movable platforms and gantry carriages, grooves with inclined guide sections 18 are made, whose tangent is determined from the condition tgjib4o6 (f + | Ud / 2) / D + 0.005, where ft is the angle of inclination; Ck - the coefficient of friction fenders on the rail; f is the rolling friction coefficient; / U is the coefficient of friction in the axles of the wheels; d is the diameter of the wheel axle; D - wheel diameter. When the winch stops, the carriage with fixed fists stops, and the mobile form with the portal connected to it. Continues to go over section 18; at the same time, the pivot of the mobile platform departs from the corresponding fixed fist, occupying a middle position between them, which ensures a guaranteed rise of the pin. .7 il with

Description

The invention relates to cargo handling and storage equipment, in particular to devices for the storage of goods, and is an improvement of the known device described in auth. No. 507496.

The aim of the invention is to increase reliability.

Figure 1 shows the proposed device; figure 2 - section aa in figure 1; in FIG. 3, node I in FIG; figure 4 - view B in figure 2; Fig 5 shows view B in Fig. 4; figure 6 - node II in figure 1; Fig. 7 is a diagram of the forces due to the pressure of the wheel on the rail on a slope.

The device for storing cargo is a few Rus

 gantry carts 1, moved cix along rails 2 with assistance to the cable-block system 3 equipped with carriage 1-sh 4 with fixed fists 5. Rope 6 passes through blocks 7 and 8, and the free ends are fixed on drums 9 of winch 10. Under portal carts I are installed Mobile platforms I1, equipped with a solenoid 12 with a pin 13 and end beams 14 o. Trolleys 1 are equipped with grippers 15 with a solenoid 16 o. The rails 17 of the mobile platform 11 have recesses with guiding inclined sections 18 with locking inclined sections 19.

The device works as follows

If it is necessary to roll out one or another cart I on the control panel, press the button with the corresponding number of the rus and the portal-type cart. This turns on the solenoid 12 and winds the pin 13 between the cams 5 of the carriage 4 of the corresponding mobile platform 1 1, but also includes solenoids 16, which turn the grippers 15 of the corresponding carriage 1 to engage them at the end beams 14. Then the winch 10 turns on and the carriage 4 rolls out cart in the international space. Upon completion of work with this cart, i.e. after unloading it or loading cargo onto it, the trolley rolls over to the initial position zone and when the rear wheels hit the recess section 18, the winch 10 is disconnected and the carriage 4 with fixed fists 5 stops and the mobile platform 11 and the portal cart 1 coupled with it 15 are stopped They move along section 18 until the rear wheels take up the position indicated in Fig. 6. In this case, the pin 13 moves away from the corresponding fixed fist 5, occupying a middle position between them, which ensures a guaranteed rise of the pin 13 by the solenoid 12 and lowering it to roll out the next rack. After that, all mechanisms return to their original position.
