To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: in the no-load state, the device takes the connecting point of the lifting rope and the elastic rope as a lifting point, the lifting point is the gravity center of the whole device, the suspender, the lifting rope and the elastic rope form a triangular stable state, and the suspender and the lifting hook are relatively horizontal, so that the lifting hook can be conveniently inserted into an object to be lifted subsequently; under the state of lifting the object, the elastic rope extends, and the gravity center of the device moves to the connecting point of the lifting rope and the lifting rod, so that the device and the object to be lifted can be smoothly lifted. The operator does not need to manually move the device in the process of hanging the objects, so that the consumption of manpower is relatively reduced, and potential safety hazards are relatively avoided under the condition that the objects to be hung are stacked in multiple layers.

Drawings

Fig. 1 is a schematic structural diagram of a double hook balancing sling.

The labels in the figure are: the lifting device comprises a lifting rod 1, a lifting hook 2, a lifting rope 3, an elastic rope 4, an extension frame 5, an auxiliary rope 6, a connecting frame 7 and an anti-skid edge 8.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, a double-hook balance hanger includes a suspension rod 1 and two suspension hooks 2 parallel to each other, and further includes a lifting rope 3 and a stretch rope 4 connected to the suspension rod 1, the lifting rope 3 is a chain, the stretch rope 4 is a spring, one end of the lifting rope 3 and one end of the stretch rope 4 are respectively close to two ends of the suspension rod 1, the other end of the lifting rope 3 and the other end of the stretch rope 4 are connected to each other, and the double-hook balance hanger is lifted by using a connection point of the lifting rope 3 and the stretch rope 4 as a lifting point.
