Description

The invention relates to a lifting machinery industry and can be used for interoperational transportation.

The aim of the invention is to reduce the metal intensity of the conveyor.

FIG. 1 shows a step conveyor, side view; in fig. 2 - the same cross section; in fig. 3 - conveyor, top view.

The stepping conveyor comprises a fixed frame 1 on which the support rollers 2 are mounted, a drive of reciprocating movement in the form of a power cylinder 3, side guides 4 for the load 5 mounted on the fixed frame 1 with the possibility of reciprocating movement of the rod 6 with articulated fixed on it by pushers 7 of one-sided action with an offset center of gravity, the rod is equipped with a rear 8 fixed on it and front 9 stops for each pusher mounted on the rod with the possibility of and with rear stop 8 when the working stroke of the rod 6, and with the front stop 9 - when idling the rod 6, On one of the walls 10 of the fixed frame 1 mounted mechanism for lifting the pushers 7 in the working position, made in the form {stops 11, each installed with the ability to interact with the corresponding pusher 7 at the beginning of the stroke of the rod 6.

The free end 12 of each pusher 7 is made of elastic material. In this case, each pusher 7 is made with a slot 13 for passing; e- a corresponding stop 11, and the axis 14 of the stops 11 and the axis of the slots 13 of the pushers 7 are at the same level with the working stroke of the rod 6. The center of gravity of the pushers 7 is shifted

relative to their vertical axis to the right.

Shagovy conveyor works as follows.

When the working stroke, the piston rod 3 (from left to right) moves the movable rod 6. The pushers 7, which were previously in a tilted position on the front stops 9, are turned by means of auxiliary stops 11 (since the free end of 12 pushers is above the stops 11) , adopting a vertical position. In this case, the axis of the slot 13 coincides with the axis 14 of the stop 11 and the pusher 7 in the vertical position passes this stop against the load 5, moves it along the support rollers

2 one step from left to right. When idling the power cylinder rod

3 (right to left) moves the movable rod 6 in the opposite direction. In this case, the pushers 7 under the action of the overturning moment of their own weight are lowered onto the front stops 9. Their free end 12 is located 2 to 3 mm stops 11, however, elastically deformed, the pushers pass these stops under the load without hitting it. For this, the free end of the 12 pushers 7, folded on the front stops 9, is below the load surface 5. The stroke of the movable rod 6 must be greater than the step of moving the load by an amount sufficient to install the pushers 7 in the vertical position. The lateral guides 4 prevent lateral displacement of the load 5. The location of the stops 8, 9, 11 and the tappets 7 must be provided for adjustable. Pushers 7 can be made in the form of elastic plates or elastic wire.
