Embodiment Construction

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described more clearly and completely below in conjunction with the accompanying drawings in the embodiments. Of course, the described embodiments are only a part of the present invention. Not all, based on this embodiment, other embodiments obtained by those skilled in the art without creative efforts are all within the protection scope of the present invention.

[0025] Such as Figure 1-Figure 6 As shown, an automatic lifting fixture includes a lifting part 1 for hoisting and a clamping part suspended below the lifting part 1 for clamping the barrel body 9. The clamping part drives the shears through the built-in hydraulic cylinder 3. One end of the fork 4 is opened and closed, and the position of the L-shaped plate 5 and the straight bar 6 at the other end of the scissors 4 is controlled.

Abstract

The invention relates to an automatic hoisting clamp. The automatic hoisting clamp comprises a hoisting portion used for hoisting and a clamping portion which is hung below the hoisting portion and used for clamping a barrel body. The clamping portion drives one ends of shear fork pieces to be opened and closed through a built-in hydraulic cylinder, position change of an L-shaped plate and a straight rod at the other end of each shear fork piece is controlled, and position change of each straight rod drives a telescopic ring connected with the straight rod fixedly to stretch out and draw backto fix the barrel body. According to the automatic hoisting clamp, the three shear fork pieces distributed annularly are controlled through the hydraulic cylinder to synchronously expand and draw back, a first plate of each shear fork piece drives the corresponding L-shaped plate to move, each L-shaped plate and a second plate of the corresponding shear fork piece jointly limit the moving direction of the corresponding straight rod, so that each straight rod carries out inward-retracting and upward operation during clamping, the corresponding telescopic ring connected with the straight rod fixedly is driven to be folded for clamping and move upwards simultaneously, and an inclined supporting plate on each telescopic ring is driven to move upwards to carry out attaching supporting and clamping on a diameter change transition portion of the outer wall of the barrel body.

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...
