An automated lifting fixture

Abstract

The invention relates to an automatic hoisting fixture, which includes a hoisting part for hoisting and a clamping part suspended below the hoisting part for clamping a barrel, and the clamping part drives the shears through a built-in hydraulic cylinder. One end of the fork is opened and closed to control the position change of the L-shaped plate and the straight rod at the other end of the scissors. The position change of the straight rod drives the fixedly connected telescopic ring to expand and contract to fix the barrel. In the present invention, three circularly distributed scissors are controlled by a hydraulic cylinder to expand and contract synchronously. The first plate of the scissors drives the L-shaped plate to move, and the L-shaped plate and the second plate of the scissors jointly define a straight bar. The direction of movement makes the straight rod move inward and upward when clamping, driving the fixedly connected telescopic ring to close and clamp while the telescopic ring moves up, driving the diagonal brace on the telescopic ring to move to the diameter of the outer wall of the barrel Change the transitional part for fitting support and clamping.

Description

technical field [0001] The invention relates to the field of fixtures, in particular to an automatic lifting fixture. Background technique [0002] The hoisting of large cylindrical or barreled objects is generally carried out after being fixed at the bottom, and then lifted by the hook, which makes the process of clamping the entire cylindrical object more time-consuming. [0003] The existing clamps usually use the traditional clip set as an arc, which is clamped from both symmetrical sides to form a way to hold and clamp the barrel body. Due to the small contact area, when the entire barrel is too heavy It is easy to slide down, and this method is also used for the variable diameter barrel whose upper diameter is larger than the lower diameter, resulting in poor overall clamping effect and easy to cause clamping instability. Contents of the invention [0004] Now in order to meet the above-mentioned requirements for adapting and clamping the variable-diameter barrel wh...
