The utility model discloses the beneficial effect who produces is: the utility model provides a promote clamping device with flange heavy object when heavy object itself does not promote with the hole, when promoting with wire rope etc. because wire rope toughness is little itself, can not reach safe clamp force when binding, this problem of solution that this device can be fine. Simultaneously, the clamp arm is hinged with the support arm, the structure is simple, the carrying is easy, the weight of a heavy object to be lifted is larger, the clamping force is larger, the cost is low due to the adoption of a sand casting, and the potential safety hazard caused by the corrosion of welding seams of the welding parts can be reduced.

Drawings

The invention will be further explained with reference to the drawings and examples, wherein:

fig. 1 is a schematic diagram of an embodiment of the present invention.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1, a lifting clamp with flanged weights includes: support arm 1 and clamping arm 2 that mutually articulate together, support arm 1 is C word column structure, support arm 1 is including hanging portion 12 and the tight portion 11 in top of holding, hang the inboard contact of portion 12 and the flange of waiting to promote heavy object 3, the tight portion 11 in top contacts with the lateral surface of waiting to promote heavy object 3, clamping arm 2 is L column structure, clamping arm 2 includes: the lifting device comprises a clamping part 21 and a lifting part 22, wherein the lifting part 22 is hinged with a lifting lug 4, the lifting lug 4 is connected with a lifting device, and the clamping part 21 is contacted with a heavy object 3 to be lifted in a lifting state.

In the preferred embodiment of the present invention, the supporting arm 1 and the clamping arm 2 are hinged by the hinge bolt 5, and the hinge bolt 5 is a hexagonal bolt that does not come off.

In the preferred embodiment of the present invention, the left side surface of the hanging part 12 contacts with the inner side of the flange of the heavy object 3 to be lifted, and the end surface of the tightening part 11 contacts with the outer side surface of the heavy object 3 to be lifted.

In the preferred embodiment of the present invention, the end surface of the tightening portion 11 is provided with a cushion pad.

In the preferred embodiment of the present invention, the clamping portion 21 is located between the hanging portion 12 and the tightening portion 11 during the lifting process.

In the preferred embodiment of the present invention, the supporting arm 1 and the clamping arm 2 are made of sand castings.

When in use, the hanging and holding part 12 of the supporting arm 1 is firstly placed on the upper surface of the heavy object 3 to be lifted, and the hanging and holding part 12 on the supporting arm 1 is contacted with the flange side surface of the heavy object 3 to be lifted; secondly, the lifting lug 4 is connected with a hoisting cable. When the lifting is carried out, the clamping arm 2 can do plane motion along with the rising of the lifting height of the lifting lug 4 until the tight pushing part 11 on the clamping arm 1 is contacted with the side surface of the heavy object 3 to be lifted, and the clamping part 21 and the tight pushing part 11 of the clamping arm 2 are positioned on the same plane and on the same straight line.
