Description

Adjustable lug lifting device

Technical field

The utility model relates to a hoisting device, in particular to a hoisting device with adjustable lifting lug positions for ensuring stable hoisting.

Background technique

At present, the known lifting device structure is made up of steel bracket, lifting lug, lifting hole. The lifting position is fixed. Although the center of gravity of the product has been accurately calculated in the design, the lifting point after manufacture and the center of gravity of the lifted product may still not be on the same plumb line. The product cannot be kept horizontal in the air during lifting, resulting in It may damage the parts of the lifting product, especially when the product needs to be lifted and lowered in the air in a horizontal state during assembly. It is still impossible to accurately control the center of gravity of the hoist, and sometimes it is necessary to increase the counterweight to achieve balance. Although this can keep the hoisted product in a horizontal state, it is very troublesome, inefficient, and brings certain safety hazards.

Contents of the invention

In order to overcome the non-adjustable lugs of the existing lifting device, the product cannot be kept horizontal in the air during lifting, eliminate potential safety hazards, and improve the efficiency of logistics and transportation within the factory.

The utility model provides a lifting device with adjustable lifting lugs, which can keep the lifting position and the center of gravity of the product on a vertical line, and keep the lifting product in a horizontal state in the air without the action of external force, which can avoid lifting Damage to parts during the process and eliminate potential safety hazards.

The technical scheme that the utility model solves its technical problem adopts is:

The lifting device with adjustable lugs includes a rigid bracket, a hoisting part and an adjusting part. There are two ear forks in the middle of the rigid bracket, and the hoisting part is installed in the middle of the rigid bracket between the two ear forks; the hoisting part consists of lifting lugs, The connecting plate I, the bottom plate, and the connecting plate II are composed of the two sides of the bottom of the lifting lug and the connecting plate I and the connecting plate II are bolted and fixed; the bottom plate is located under the rigid bracket and is connected and fixed with the connecting plate I and the connecting plate II; The adjustment screw, the adjustment handle, the slider, and the ear fork are composed. The adjustment screw passes through the holes of the two ear forks and the slider, and cooperates with the slider thread. The slider is fixed between the connecting plate I and the connecting plate II. The adjusting screw The left end of the handle is shaped on a stepped surface whose diameter is larger than the hole of the ear fork. The stepped surface of the adjusting screw fits on the inner surface of the ear fork, and the adjusting handle is set on the left end of the adjusting screw outside the ear fork and fixed.

In the lifting device with adjustable lugs of the present invention, steps are formed on the connecting plate I and the connecting plate II corresponding to the bottom of the bottom plate for supporting the bottom plate.

In the lifting device with adjustable lugs of the present invention, bosses (11) are formed at both ends of the slider (3), and connecting plate I and connecting plate II are formed with oblong holes (10) matching the bosses, so that the sliding Block (3) can move up and down along oblong hole (10).

In the lifting device with adjustable lugs of the present invention, the adjusting handle is fixed on the adjusting screw with a stop pin.

In the lifting device with adjustable lugs of the present invention, the rigid bracket is provided with a scale, and the connection plate I and the connection plate II are respectively provided with observation holes corresponding to the scale.

The lifting lugs, connecting plate I, bottom plate and connecting plate II of the adjustable lifting lug lifting device can move along the rigid bracket after being combined, and the bosses at both ends of the slider can move up and down along the oblong hole, adding a set of lugs to the rigid bracket. Fork hole, the adjusting screw passes through the ear fork hole, screwed into the threaded hole of the slider, and unscrewed from the other ear fork hole until the step surface of the adjusting screw fits the inner surface of the ear fork, and the adjustment handle is sleeved from the other side of the ear fork Insert the adjusting screw and fix it with a stop pin. After fixing, the step surface of the adjusting screw and the end surface of the adjusting handle act on the two ends of the ear fork hole to limit the movement of the adjusting screw along the axis of the ear fork hole. It can only rotate freely along the axis of the fork ear hole. The rotation of the adjusting screw and the adjusting handle can be converted into translational movement along the ear fork hole and the axis of the ear fork hole, and at the same time drive the ear fork to translate along the rigid bracket. A scale is set on the rigid bracket. An observation hole is used to determine the precise position of the lifting lug and play a role in adjusting the position of the lifting lug.

The beneficial effect of the utility model is that the improved adjustable lifting lug lifting device is reasonable in structure, convenient and reliable, does not require manual intervention, keeps the lifting product in a horizontal state in the air, is beneficial to the assembly of parts, and avoids damage to parts during the lifting process. Eliminate security risks.
