Abstract

CONVEYOR FOR VERTICAL MOVEMENT OF CARGO, including sprockets mounted on the frame, bending around two traction chains with levers, pairwise and hinged with one ends on the bushes of the traction chains, the other ends of which are located outside the trajectory of the traction chains and are connected by suspension axles which load-carrying shelves are fixed, characterized in that, in order to simplify installation and increase the degree of unification, it is provided with strips having lugs at one end with radius grooves for bushings the traction chains, and the levers on one side at the junction with the bushings of the traction chains are made with grooves, while one of the levers is made with a groove on the side surface, and the others with a lug located in the groove, and the other ends of the planks are rigidly fixed in the slots of the levers, and the protrusions on the slats are made with a height equal to the distance between the plates of the drag chains and with a bevel for the teeth of the sprockets.

Description

The invention relates to industrial transport, namely to conveyors for the vertical movement of goods.

The purpose of the invention is to simplify installation and increase the degree of unification.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 - lever with boss; in fig. 5 - the same, top view; in fig. 6 - lever with recess; in fig. 7 - the same, top view; in fig. 8 - plank, general view; in fig. 9 is a view of B in FIG. eight; in fig. 10 is a view of FIG. eight; in fig. 11 view D in FIG. eight; in fig. 12 is a view of E in FIG. 8; in fig. 13 is a view of FIG. 12.

The conveyor for the vertical movement of goods contains a frame 1 with asterisks 2 fixed on it, enveloping them endlessly closed traction chains 3 with horizontal load carrying shelves 4, in which the suspension axles 5 are mounted on the ends of the support arms 6 and 7. The levers 6 and 7 on their other the ends are made with a groove 8 having a width equal to the diameter of the sleeve 9. One lever 6 is made with a boss 10, the other 7 - with a groove 11. The levers 6 and 7 are aligned so that the boss 10 of the lever 6 enters the groove 11 of the lever 7. Levers 6 and 7 put on groove 8 on the sleeve 9 of the chain 3 on its internal h nce between the plates 12. On the side surface of one of the levers (lever with lug 10 b) is fixedly secured at its one end plate 13 at the other end having a projection 14 with a radiused notch 15 formed across the height of the projection 14. Strap 13

the recess 15 covers the sleeve 9, overlapping the groove 8 of the levers 6 and 7 with the protrusion 14. The height of the protrusion 14 of the bar 13 corresponds to the distance between the plates 12 of the chain 3, thereby eliminating the possibility of displacement of the levers along the sleeve of the chain. A part of the protrusion 14 of the bar 13 is made with a bevel 16 for the uninterrupted passage of the tooth of the sprocket 2. Thus, the arms with the bar form a permanent connection,

 allowing the levers 6 and 7 to rotate relative to the sleeve 9 and securely hold the load carrying shelf 4 in the extreme upper and lower position when one of the pair of levers is under the sleeve

5 9 groove 8 up.

 In order to arrange the movement of the load carrying shelves 4 when they come off the curved section on the end surface of each shelf 4, an emphasis 17 is installed in its middle part, in the form of a plate bent at an angle, with an angle upwards.

The device works as follows.

When the motor is turned on (not

5 is shown) the sprockets 2, rotated on frame 1 and engaging with the drag chain 3, begin to rotate. The movement is transmitted to the load-carrying shelves 4, which are connected to the axes of the suspension 5 connected to the ends of the chains 3.

0 levers 6 and 7. When the load carrying shelves 4 exit the curvilinear section, the stops 17 interact with the suspension axles 5 of the lower carrying load shelf 4, preventing them from swinging.
