Abstract

FIELD OF THE INVENTION The invention relates to a lifting and transport equipment, in particular to lifting devices. The aim of the invention is to reduce energy consumption in the seizure of cargo from both inside and outside. The load gripping device comprises a ram 1 with a rod 2, gripping levers 4 connected to it, for end 7 connected to each other by a common horizontal axis 8 at one end, and the additional end attached to gripping levers 4, the additional end 10, the upper end connected with the power cylinder 1, and the lower one - either with gripping levers 4, or - with a common horizontal axis B, 2 Il.

ABOUT

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

The purpose of the invention is to reduce the energy intensity in the seizure of cargo as a dream.

guns, so from the inside.

Figure 1 shows the load handling device in the position for transporting cargo when it is wrapped outside, a general view; figure 2 - the same, when exposed to cargo from the inside.

The load gripping device, which is hung on the hook of the load-lifting mechanism or the crane arm, contains a power cylinder 1 with a rod 2 having the possibility of reciprocating motion and connected by means of horizontal axes 3 with gripping levers 4, the main 5 and additional 6 operating members fixed to the lower the ends of the gripping levers 4, ti gi 7, one end connected to each other by a common horizontal axis 8, and the other end hinged on the gripping levers 4 rigidly fixed in the upper x parts of the gripping fingers 9 of the arms 4, additional rods 10 fixed at one end on the housing of the actuator 1 to be attached on the other ends of the fingers 9, or on the axis 8.

The device works as follows.

Capture cargo from the outside. The device hinged on the hook of the load-lifting mechanism or the boom of the manipulator is in the unloaded state - the rod 2 of the power cylinder 1 is retracted, the additional drafts 10 are fixed to the common horizontal axis 8 by the lower ends, and the levers 4 are separated to the side. After supplying the device 9a to the load, the rod 2 is extended, while the end of the rod 2 moves downward along with the upper ends of the gripping levers 4, the lower ends of which move downwards and simultaneously converge due to the fact that the ends of the tg 7 fixed on the gripping levers 4 turn relative to a common horizontal axis 8. The main working bodies 5 cover the surface of the cargo from the outside and exert on it a force that reliably holds the load. The release of the load is carried out by pulling the rod 2.

Capture cargo from the inside. This requires disconnecting the lower KON11M additional tons of 10 from the common horizontal axis 8 and connecting them with the gripping levers 4 by means of the fingers 9. The device hung on the hook of the load-lifting mechanism or the boom arm is in the unloaded state — the rod 2 of the power cylinder 1 is retracted, the additional rods 10 lower ends are fixed on the gripping levers 4, which are close to each other. After the gripper is supplied to the load and the gripping levers 4 are lowered, the rod 2 is pushed into the load cavity, and The dry ends of the gripping arms 4. At the same time, the lower ends of the additional tg 10 are moved upwards and to the sides relative to the end of the brush 2, and the lower ends of the gripping levers 4 move away from each other, turning the circle of the axes 3 until the additional working members 6 are pressed into the walls load cavities. The load is held by the action of friction. The release of the load is carried out by retracting the rod 2 of the power cylinder 1.

Claims (1)

Claims: Load-carrying device, comprising a carrier element, gripping levers fixed on horizontal axes with working bodies at the ends of the lower arms with a side hinged on them with their ends at one end relative to the vertical axis of symmetry, the other ends being connected to each other a common horizontal axis, and a cylinder to be mounted vertically in a bearing element for moving gripping levers, characterized in that, in order to reduce energy intensity in the seizure of cargo, from the outside and from the inside, the horizontal axes of the double-arm levers are fixed at the end of the power cylinder rod, and the hinges are fixed in the lower parts of the gripping levers, and the device is equipped with additional working bodies rigidly fixed to the ends of the levers on their outer side, rigidly fixed in the upper parts of gripping levers with the fingers fixed on the body with connection to: common horizontal axis of main m M ends of additional rigid t gami. cpupSL
