The invention relates to lifting equipment, in particular; to the load-handling vacuum chambers of lifting devices, and is intended to capture, lift and transport piece goods.

Known vacuum capture, comprising a housing, a chamber formed by a membrane fixed along the perimeter of the housing, and a seal located between the housing and the membrane tl

A disadvantage of the known grip is the short service life of the seal due to its deformation during the formation of a vacuum in the chamber.

The purpose of the invention is to increase the durability of the grip.

To achieve this goal, in a vacuum gripping device comprising a housing, a chamber formed by a membrane fixed along the hull's perimeter, and a seal located between the housing and the membrane, the membrane is fixed on the housing to form cavities between it, the outer and inner walls of the seal, the latter of which are through channels made in the housing connected to the cavity of the camera.

FIG. 1 shows a vacuum gripper, cross section; in fig. 2 view A in FIG. one; in fig. 3 is a section BB in FIG. 2

The vacuum gripper comprises a housing 1 with a vacuum gripping chamber having a seal 2 along the perimeter, which is pressed against the housing 1 by means of an elastic membrane 3. The membrane 3 is attached to the housing 1 by an internal pressure ring 4 and an external pressure ring 5, which, in turn fixed to housing 1 with screws b. Lifting and lowering of the vacuum chamber is carried out through the board 7. To connect the chamber with a vacuum source, the housing 1 is made with a hole to which the connecting pipe 8 is connected.

Between the membrane 3 and the seal 2, the inner 9 and outer 10 annular closed cavities are formed, the inner 9 of which are connected to the vacuum-gripping chamber by channels 11 made in the housing 1.

Vacuum gripping works as follows.

Through pipe 8 begin to pump out the air. The resulting vacuum presses the seal 2 and the membrane 3 to the housing 1. Thanks to the channels 11, the seal 2 is prevented from shifting into the middle of the vacuum chamber, since vacuum also forms in the cavity 9, under the action of which the membrane 3 presses against the protrusion of the housing 1, thereby providing , permanent form of seal 2,

The proposed implementation of the vacuum pickup prevents deformation of the seal, which will increase its service life and reliable operation.
