Abstract

FIELD OF THE INVENTION The invention relates to lifting and handling equipment and concerns the design of the telescopic gripping of the stacker crane. The aim of the invention is to simplify the grip structure. The telescopic grip contains base 1 and platforms. When the gearmotor 19 is turned on, the screw 21 is driven into rotation, moving the nut 22 together with the platforms that are included in the container opening installed in the cell of the rack. When lifting the stacker carriage and moving the platforms, the container is removed from the rack. The implementation of chain bodies in the form of open loops reduces the required number of stars and thereby simplifies the design of the grip. 6 Il.

WITH

The invention relates to lifting and handling equipment, namely, to telescopic grippers of a lifting machine, preferably a stacking crane.

The gripper to the stacker crane is known, which contains dual composite rods, each of which includes intermediate and load-carrying sections equipped with rollers and moving from a single drive.

A disadvantage of the known grip is the complexity of the design.

The closest in technical essence to the invention is a telescopic grip of a lifting machine, comprising a base, parallel platforms installed one on another, lifting platforms each connected to a corresponding intermediate platform and base by means of at least one chain organ enveloping sprockets mounted on the base and connected to one of the intermediate platforms, and a device for connecting one of the sliding platforms between a boom mounted on the side of one of these platforms and placed with a free end in a groove made on the side of an adjacent sliding platform.

The disadvantage of the known telescopic capture is the complex structure of the chain organ.

The purpose of the invention is to simplify the design.

This goal is achieved by the fact that the chain bodies are connected with the asterisks of the corresponding platform and the base to form open loops directed against adjacent parallel platforms in opposite directions, with the bar fixed on one of the load carrying platforms and the groove on the other similar platform.

Figure 1 shows a telescopic grip, a general view; figure 2 is a view of And figure 1; on fig.Z - section bb in figure 1: on figure 4 - section bb In figure 2: on figure 5 - section d-y on figure 2: on figure 6 - section d- D in figure 2.

The telescopic grip of a lifting machine, preferably a crane-bebel, contains base 1, parallel to each other intermediate platforms 2 and 3 mounted on it, lifting platforms 4 and 5, each connected to a corresponding intermediate platform and base by means of a chain link 6 or 7, connected with asterisks 8 and 9 with the formation of open loops (chains 10 and 11) directed at adjacent parallel spaced platforms in opposite directions, while the rod 12 is fixed on the platform 4, and the groove 13 is nen in the platform 5. The intermediate platform 2 and 3 and the base 1 are provided with guides 14-16 interacting with rollers

17 and 18, fixed on the axles in platforms 4 and 5. The movement of the platforms includes a gear motor 19, a flexible gear 20 and a screw 21. The nut 22 of the screw 21 is fixed to the bottom of the platforms 2 and 3. The chain 10 is single

end mounted on the platform 5, goes around the stars 8 and 9 and the other end attached to the base 1. Chain 11 goes around the stars 8 and 9 mounted on the opposite side of the platform 4 and

bases 1.

Telescopic capture works as follows.

When the gearbox motor 19 is turned on, the screw 21 is moved into rotation, moving the nut 22 together with the platforms 2-5, the latter entering the container opening (not shown) installed in the cell of the rack. When the stacker carriage is lifted and the platforms move, the container with the load is removed from the rack and moved according to the stacker's specified work program. Thus, the implementation of chain bodies in the form of open loops reduces the required number of stars and simplifies the design of the telescopic grip.
