Abstract

Usage: the invention relates to a lifting and transport equipment, in particular to grippers for loads with openings. SUMMARY OF THE INVENTION: The gripper for cargo with openings comprises a housing 1. A housing 1 is made in the lower part with an outer protrusion 6, radial grooves 2 and with a central opening 3, In the central opening 3 there is a rod 4. At the end of the rod 4 there is a spherical thickening 5, a ring 7 is located on the protrusion 6; In the radial grooves 2 of the housing 1, there are gripping levers 8 arranged with apertures 9 with which they surround the ring 7. 2 Cp. f-ly, 3 ill.

Description

The invention relates to lifting equipment.

Known grip for loads with holes, comprising a housing having on the outer surface symmetrically located open bottom radial grooves and a Central hole located in the Central hole of the housing with the possibility of vertical movement of the rod with a thickening at the lower end and a hanging element on the lifting mechanism on the upper and gripping levers , - each located with its upper end in the corresponding groove of the housing and each connected with the latter pivotally with the possibility of rotation in a vertical plane and interaction of the inner surface of working ends with a thickening of the rod while maintaining a secure grip.

The known capture is not quite convenient in operation due to the complexity of its disassembly for repair.

The aim of the invention is to improve ease of use.

To achieve the goal of a cargo grip with holes, comprising a housing having, on the outer surface, symmetrically located radially open bottom openings and a central hole located in the central housing opening with the possibility of vertical movement of the rod with a thickening at the lower end and a hanging element on the load-lifting mechanism at the upper and gripping levers, each located with its upper end in the corresponding groove of the housing and each connected with the latter pivotally with the possibility of rotation in vertical plane and the interaction of the inner surface of the working ends with a thickening of the rod while maintaining a reliable grip, the housing in the lower part is made with an annular protrusion, the gripping levers are pivotally connected to the housing by means of the last removable ring located on the said protrusion, and are made on the upper shoulder with a pharynx the radius of the cross section of the ring, covering the latter with the possibility of supporting the rear surface of the gripping levers on the rod above the thickening, made spherical.

In FIG. 1 shows a grip; FIG. 2 is the same, an embodiment; in FIG. 3 - the same, the third embodiment.

The gripper for loads with holes contains a housing 1. The housing 1 is made with radial grooves 2 located ^ symmetrically and open from below. The housing 1 is also made with a Central hole

3. In the central hole 3 of the housing 1, the rod 4 is located, the rod 4 has the ability to move vertically and is made with a spherical thickening 5 at the lower end and the hanging element A on the upper. The housing 1 in the lower part is made with an annular protrusion 6. The housing 1 covers a removable ring located on the protrusion 6. The gripping levers 8 are made in the upper part with a pharynx 9 along the radius of the cross section of the ring 7, hung by the pharynx on the ring with the possibility of supporting the back surface on the rod 4 and above the bulge 5 and placed in the grooves 2 of the housing 1. The rod 4 and the spherical bulge 5 can be made with a thread 10 for connection with each other. The protrusion of the housing can be performed on the upper surface with an annular groove. The gripper is introduced into the cargo hole, the housing 1 is lifted up the rod 4, the gripping arms 8 are in a reduced state. In the cargo hole, the housing 1 is released and, under the influence of its own weight, slides down the rod 4. The gripping levers 8 slide along the spherical bulge 5, resting against the walls of the cargo hole. The grip rises, a spherical thickening pushes the gripping arms 8. The load is held securely.

This grip, if necessary, can simply be disassembled. To do this, the spherical thickening is turned away from the rod, the housing with the gripping levers and the ring is removed from the rod, the gripping levers are removed from the ring. In the reverse sequence, the capture is collected.

Claims (3)

Claim 1. A cargo grip with holes, comprising a housing having, on the outer surface, symmetrically located radial grooves open from below and a central hole located in the central hole of the housing with vertical movement of the rod with a thickening at the lower end and a hanging element on the load-lifting mechanism at the upper and gripping levers, each located with its upper end in the corresponding groove of the housing and connected each with the latter pivotally with the possibility of rotation in the vertical plane and action of the inner surface of the working ends with a thickening of the rod while maintaining a reliable grip, characterized in that, in order to improve ease of use, the housing in the lower part is made with an annular protrusion, the gripping levers are pivotally connected to the housing by means of a female removable ring located on the said protrusion , and are made on the upper arm with a pharynx along the radius of the cross section of the ring, covering the latter with the possibility of supporting the back surface of the gripping levers on the rod above e thickening made spherical. 2. Capture pop. 1, characterized in that the rod and the thickening is made 5 respectively with external and internal threads for connection with each other. 3. Gripping on PP, 1 and 2, distinguished by the fact that the annular protrusion of the housing on the upper surface is made with an annular 10 by the groove in which the ring is located. figure 2
