RU16353U1 - CARGO HOOK - Google Patents

Abstract

A cargo hook containing an eye for securing a lifting mechanism to an actuator, characterized in that the eye is removable and provided with a glass containing a bracket for the suspension, and a bearing is mounted in the cavity of the glass, on which a cylindrical rod with a transverse hole at the lower end rests, kinematically connected with the detachable element of the hook and eye.

Description

The claimed technical solution relates to the production of crane manipulators mounted on land vehicles, in particular, to cargo hooks

It is well known that a cargo hook contains an eye for securing a lifting mechanism to an actuator. Moreover, the eye is made with a cargo hook in the form of a monolithic structure. A disadvantage of the known technical solution is that the known cargo hook does not allow to turn the lifted load at significant turning angles.

Closest to the claimed one is a cargo hook containing an eye for securing a lifting mechanism (1) to an executive body. In the known cargo hook, the eye is removable and connected to the cargo hook via an axis. fixed in the holes of the cargo hook and eye.

A disadvantage of the known technical solution is the insufficient reliability of securing the eye, since with a large lifting capacity of the hook, friction between the axis and the flange of the joint of this axis increases

with a cargo hook and with an eye, which reduces the possibility of manipulating the load around this axis. In addition, due to increased friction and wear, the known hook has a low service life.

The purpose of the proposed technical solution is to eliminate this drawback, namely, improving the efficiency of cargo handling and improving the reliability of the cargo hook ..

This goal is achieved by the fact that in the cargo hook containing an eye for securing the lifting mechanism on the actuator, the eye is removable and provided with a glass, containing an arm for suspension, and a bearing is mounted in the cavity of the glass, on which a cylindrical rod with a transverse shaft is supported a hole at the lower end, kinematically connected with the detachable connection element of the hook and eye.

The proposed technical solution is illustrated by the drawing.

FIG. 1 - General view of the cargo hook, section.

The cargo hook 1 contains a removable eye, made in the form of a glass 2 with an arm 3 for suspension on the executive body of the lifting mechanism. Bearing 4 is mounted in the cup 2 and is fixed by means of the cover 5 using a threaded connection. A cylindrical rod b with a fifth 7 is supported on the bearing 4. The lower end of the rod 6 is made with a groove 8 in which an axis 9 is installed, by means of which the detachable connection element 10 of the hook and the eye is jointed. Moreover, the element 10 is made in the form of an eye connected to the cargo hook by means of a threaded connection. The proposed solution has new functionality for handling raised loads. In the drawing, the arrows show the directions for handling the load, i.e. the claimed cargo hook has three

degrees of freedom with increased reliability of its elements. None of the known analogues has such properties.

The use of the claimed technical solution is carried out by traditional methods used in the operation of hoisting mechanisms in the national economy. The authors conducted experimental work on the manufacture and testing of the claimed technical solution. The test results showed the reliability and effectiveness of the proposed cargo hook.
