The utility model aims to provide a: to the problems existing in the prior art, the overturning lifting appliance is low in cost and convenient to use.

The purpose of the utility model is realized through the following technical scheme:

a roll-over spreader comprising: the crane hook is arranged on a movable crane in the upper space of the workshop; the first hoisting piece comprises a connecting end and a hoisting end, wherein the connecting end is hoisted to the crane hook, and the hoisting end is used for hoisting a workpiece; the hoisting equipment comprises a hoisting part, an installation part connected to the upper end of the hoisting part and a hoisting part connected to the lower end of the hoisting part, wherein the hoisting part drives the hoisting part to hoist, and the installation part is hoisted to the crane hook; and the second hoisting piece comprises a connecting end hoisted to the hoisting part and a hoisting end for hoisting the workpiece.

Furthermore, the hoisting equipment is an electric hoist, a manual hoist or other hoisting equipment.

Further, hoist and mount portion is the electric block lifting hook, electric block's jack-up portion drives the electric block lifting hook and promotes or transfers.

Furthermore, the first hoisting piece is a flexible hoisting cable, the connecting end of the first hoisting piece is an annular connecting sleeve hoisted on the hoisting hook, and the hoisting end of the first hoisting piece is an annular hoisting sleeve penetrating through a hoisting point on the workpiece.

Furthermore, the second hoisting piece is a flexible hoisting cable, the connecting end of the second hoisting piece is an annular connecting sleeve hoisted on the hoisting part of the hoisting equipment, and the hoisting end of the second hoisting piece is an annular hoisting sleeve penetrating through a hoisting point on the workpiece.

Further, the length of the first lifting piece is larger than that of the second lifting piece.

The beneficial effects of the utility model are mainly embodied in that: the common travelling crane, hoisting equipment and hoisting piece in the workshop environment are directly combined to form the turnover lifting appliance of the workpiece, so that the existing resources are fully utilized, special equipment is not needed, the lifting appliance is not needed to be replaced, and the cost is low; the turnover is stable, and the use is convenient and reliable.

Detailed Description

The following describes specific embodiments of the present invention with reference to the drawings.

As shown in fig. 1, the turning sling mainly comprises a crane hook 1, a hoisting device, a first hoisting member 3 and a second hoisting member 4. Wherein the crane hook 1 is arranged on a movable crane in the upper space of the workshop. The hook-shaped part of the service hook 1 hooks the first lifting element 3, in particular a flexible hoisting cable, and the hoisting device.

Hoisting equipment specifically is electric block 2, and electric block 2 includes jack-up portion, connects in the installation department of jack-up portion upper end and connects in the hoist and mount portion of jack-up portion lower extreme, specifically is electric block lifting hook d, jack-up portion drives hoist and mount portion jack-up, the installation department hang connect in driving hook 1. Alternatively, the lifting device may be a hand hoist or other lifting device that is easily found and interchanged in a workshop environment.

The first hoisting member 3 is a flexible cable, which includes a connecting end connected to the crane hook 1 and a hoisting end for hoisting a workpiece, more specifically, the connecting end is an annular connecting sleeve hoisted to the hook, and the hoisting end is an annular hoisting sleeve passing through a hoisting point on the workpiece, however, the connecting end and the hoisting end may be other structures for facilitating connection and hoisting. (ii) a The second hoisting member 4 is also a flexible hoisting cable, which includes a connecting end suspended to the hoisting portion of the electric hoist 2 and a hoisting end for hoisting a workpiece, more specifically, the connecting end is an annular connecting sleeve suspended to the hoisting portion, and the hoisting end is an annular hoisting sleeve passing through a hoisting point on the workpiece, however, the connecting end and the hoisting end may be other implementation structures for facilitating connection and hoisting. Alternatively, the first lifting element 3 and the second lifting element 4 may be booms, booms or other lifting devices that are easy to find and replace in a workshop environment. In order to facilitate the overturning after hoisting, the length of the first hoisting piece is larger than that of the second hoisting piece.

The turning spreader described above is used for lifting and turning large workpieces in a workshop, in this embodiment a gearbox 5. As shown in fig. 1, the gear box 5 has a center of gravity c, and two lifting points, a first lifting point b and a second lifting point a, respectively, are located on both sides of the center of gravity c. When the hoisting and overturning work is required, the first hoisting member 3 and the second hoisting member 4 can be respectively hoisted to the first hoisting point b and the second hoisting point a of the gear box 5. Then start electric block 2, make its electric block lifting hook 4 of lower extreme promote or transfer to drive and transport second lifting and hanging 4 and promote or transfer, thereby make the first lifting point a of gear box 5 (or other work pieces) take place to overturn around second lifting point b, finally realize the arbitrary angle upset of gear box 5 (or other work pieces) within 180.

In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
