Abstract

The invention relates to lifting transport equipment, in particular, to load handling devices. The purpose of the invention is to reduce metal content and increase safety in operation. The load gripping device contains two shoulders intersecting levers 1 with longitudinal apertures 2 fixed on a central common axis 3 rigidly fixed on the ends T {tr 4, the other ends of which are connected by a cross member 5 to the stem 6 of the power cylinder 7. The power cylinder 7 is connected to the cheeks 9 At the ends of the cheeks, a horizontal transverse axis 10 is fixed, the ends of which are mounted in the longitudinal grooves 11, and the middle part is located in the longitudinal holes, 2 slugs.

Description

The invention relates to a lifting machinery, in particular to a lifting device.

The purpose of the invention is the reduction of metal consumption and increased safety of operation.

Figure 1 shows the lifting device in the open position, a General view; FIG. 2 is a section A-A in FIG. 1,

A load gripping device hinged on a hook of a load-lifting mechanism or a boom of a manipulator contains a double arm with crossed arms 1 with longitudinal holes

2, reinforced ha central common axis 3, fixed motionless on. the ends of t g 4, the other ends of which are connected by a cross-member 5 fixed on the end of the rod 6 of the power cylinder 7. The rod has the possibility of reciprocating motion, and the power cylinder is connected by means of a pin

8 with cheeks 9 hung on the hook of the load gripping mechanism or a crane arm. At the ends of the cheeks

9 has a horizontal transverse axis 10J the middle part of which enters the longitudinal apertures of 2 levers 1

with the possibility of free movement, and the ends are fixed on the ends of the cheeks 9, In this case the gi 4 have longitudinal grooves 11 for the ends of the horizontal transverse axis 10,

Load handling device operation em as follows.

The device, hinged on a hook of the lifting mechanism or a boom of the manipulator, is in the closed position. When the device is lowered onto the rod 6 of the power cylinder 7, it pulls in, moving the cross member 5 with t 4 and 4 and the central axis

3. At the same time, the central axis 3 prnbli

extends toward the transverse axis 10, and thereby the levers 1 with the longitudinal apertures 2 slide along the transverse axis 10 and their ends diverge to the sides. The device is open

In order to grip the load, the bmill of the power cylinder .7 extends, moving down the crossmember 5 with tangles D and the central axis 3, which is removed from the transverse axis 10, bringing the ends of the levers 1 closer to each other sa by moving their longitudinal orifices along the spring axis ten
