Abstract

This invention relates to a lifting and transport machinery. The purpose of the invention is to increase reliability. The gripping device for goods with a pin and a figure head 18 includes a housing 1 in which a rod 5 is mounted, spring-loaded 24 with copier teeth 6 and 9, cooperating with a finger 12 mounted in the housing. At the end of the rod 5 with the possibility of rotation relative to the housing 1 in the bearings 26 mounted gripping body 15, while the end of the rod enters the cavity of the gripping body on the value of its stroke. When the load is gripped, the head 18 rests on the end of the stem 5, moving it upwards and through the teeth 6 and 9 and the finger 12 turning it. At the same time, the gripping body 15 only rotates at the required angle, not moving upwards, which allows for securely gripping the loads that are out of alignment.

FIELD OF THE INVENTION The invention relates to hoisting and transport machinery, namely, load handling devices.

The purpose of the invention is to increase the reliability of work.

FIG. 1 shows the device, a general view; in fig. 2 - view with captured cargo; in fig. 3 is a section A-A in FIG. 2

The gripping device comprises a housing 1 mounted on a carrier beam 2 of the lifting and transporting machine. Adjustable stops 4 are installed coaxially to the body 1 on the floor of the frame 3 of the hoisting and transporting system.

In the housing 1, axial movement and rotation are provided with a brush 5, on which the upper sleeve 6 is rigidly fixed with four copying teeth 7 and the lower sleeve 8 with similar teeth 9.

In the housing 1 opposite to each other, there are two glasses 10, in which fingers 12 are mounted on the bearings 11 for engagement with teeth 7 and 9. The upper part 1 of the flow 5 has a finger 13 for turning with a key. In the lower part of the rod 5 are made slots 14, on which is mounted a gripping body 15 placed in the housing 1 with the possibility of rotation. On the lower end surfaces of the housing 1 and the gripping body 15 there are conical surfaces 16 and 17 for the pin 18 of the load 19. In the lower part of the gripping body 15 there is a groove 20 formed by the projections 21 with the supporting surface 22. On the rod 5 there is a supporting surface 23. The housing 1 has a spring 24 which, through the thrust bearing 25, pushes the rod 5 down. The axial movement of the gripping body 15 is limited by the stops 26, which are made in the housing 1. In the place of contact of the lugs with the gripping body 15, sliding bearings can be installed. The lower end of the rod with the splines 14 is placed in the cavity of the gripping organ 15 by a distance equal to the stroke of the rod. .

The device works as follows.

Lower the device so that the pin 18 of the load 19 rests on the tapered top

Body 16 of the housing 1. The head of the pin 18 passes through the groove 20 into the cavity of the gripping body 15, centering relative to it. In this case, since the gripping body is fixed without the possibility of axial movement, itc-KJ allows it to be activated prematurely. Upon further lowering of the device, the pin 18 acts on the lower bearing surface 23 of the rod 5, which compresses the spring 24. The tooth 9 of the lower sleeve 8, interacting with the iMH 12 bar, rotate the rod 5 by approximately 4 j °. Through the rod 5, the gripping opr.iH 15 is rotated, and its protrusions 21 extend under the head consoles of the pin 18.

When the device is raised, the tooth 7 of the sleeve 6, interacting with the axles, turns the brush 5 and the gripping body 15 by 45 ° further, while the head of the pin rests fully on the surface 22.

After lifting the beam 2 to the upper position, the upper end of the rod 5 with a flat 13 abuts against the stop 4 on the frame 3, which eliminates the arbitrary actuation of the device during transport.

Cargo release is carried out in reverse order.
