Description

Technical Field

[0001] The utility model relates to the technical field of lifting tools, and particularly relates to a portable sheet metal part lifting tool. Background Technique

[0002] Sheet metal is a comprehensive cold working process for metal sheets (usually below 6 mm), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming, etc. Its remarkable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts. Currently, for the forming of sheet metal parts, stamping devices are usually used for stamping and forming. Through the mutual cooperation of the upper die and the lower die, the sheet can be stamped into a sheet metal with a shape that meets the requirements.

[0003] The sheet metal box body is welded by sheet metal parts. After the sheet metal box body is welded, it needs to be lifted to other areas. During this process, lifting tools are usually used to lift the sheet metal box body. A lifting tool refers to a device for lifting heavy objects in a hoisting machine. The most commonly used lifting tools for lifting finished items are hooks and slings. There are also other lifting rings, lifting suction cups, clamps, and forklift tines, etc., which are widely used in the hoisting and lifting industry.

[0004] In the prior art, such as a Chinese patent with the application number 202322787159.X, the authorized announcement number CN220845109U, and the name of a new type of portable lifting tool. In the above patent, a new type of portable lifting tool is disclosed, including a drum and a disc motor. The drum is a hub structure. A number of spokes are equidistantly arranged on the circumferential inner wall of the drum, and the spokes are all arranged along the radial direction of the drum. A central ring is arranged between the inner ends of the spokes, and the central ring is concentric with the drum. The outer diameter of the disc motor is adapted to the inner diameter of the drum. The disc motor is nested inside the drum, and the transmission shaft of the disc motor is fixedly connected to the central ring. An annular groove B is opened on the circumferential side wall of the disc motor, and an annular groove A is opened on the circumferential inner wall of the drum. A number of balls are arranged between the annular groove A and the annular groove B. A connecting seat is fixedly arranged at the end of the disc motor, and the connecting seat is located outside the drum. A lifting rope is arranged on the drum, and a hook is connected to the end of the lifting rope.

[0005] The lifting tool in the above patent has the advantages of simple and compact structure, light weight, easy to carry and handle, etc. As is known, in the prior art such as the above patent, for the sheet metal part lifting tool during use, generally, after the outside of the workpiece is fixed by fastening components, the workpiece is lifted by the lifting tool. However, due to the large size of the sheet metal box body, it is not only inconvenient to install the fastening components, but also because the outer surface of the sheet metal box body is relatively smooth, during the lifting operation, the fastening components are likely to fall off, which has certain deficiencies. Content of the Utility Model

[0006] The purpose of the present utility model is to provide a portable sheet metal part hoist to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the present utility model provides the following technical solution: A portable sheet metal part hoist, including a lifting ring, both sides of the bottom of the lifting ring are fixedly connected with mounting rods, each mounting rod is provided with a mounting ring, the mounting ring is fixedly connected with a lifting plate, and a lifting space is arranged at the bottom of the lifting plate for clamping a workpiece; a lifting part is arranged on the top of the lifting ring.

[0008] Further, the mounting ring is rotatably connected with the mounting rod.

[0009] Further, a torsion spring is arranged between the mounting ring and the mounting rod, and the elastic force of the torsion spring drives the lifting plate to be in a retracted state.

[0010] Further, a damping member is arranged between the mounting ring and the mounting rod.

[0011] Further, the lifting part is arc-shaped.

[0012] Further, a backing plate is fixedly connected to the lifting part, and a lifting groove is formed in the backing plate.

[0013] Further, a protective plate is welded at the connection between the lifting ring and the mounting rod, and the protective plate is triangular.

[0014] Further, the bottom of the lifting plate is U-shaped for mounting a workpiece.

[0015] Further, a friction block is fixedly connected inside the lifting space, and multiple groups of friction stripes are formed on the friction block.

[0016] Further, the friction block is made of an elastic material.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: for this portable sheet metal part lifting tool, through the cooperation among the lifting ring, mounting rod, mounting ring, lifting plate and lifting part, when it is necessary to use this lifting tool, first drive the lifting plate to rotate and drive the lifting plate to be clamped on the inner wall of the sheet metal part box body, and then drive the lifting plate to rotate so that the lifting plate is in a clamped state with the sheet metal part box body, avoiding the situation of the lifting plate falling off. After the clamping is completed, use an external device to lift the lifting ring through the lifting part. During the upward lifting stroke of the lifting ring, drive the lifting plate to slide upward, and lift the sheet metal part box body through the lifting plate. At this moment, since the lifting plate is in a clamped state with the sheet metal part box body and there is an upward force on the lifting plate due to the external force, the lifting plate cannot be separated from the sheet metal part box body. Therefore, the risk of the sheet metal part box body falling off during the hoisting process can be reduced, and the effect is better. When the hoisting is completed, after driving the lifting ring to be unlocked, remove the lifting plate from the sheet metal part box body. Therefore, the practicability of this sheet metal part lifting tool can be greatly improved, and this lifting tool has a simple structure and low cost, and is suitable for wide promotion and use.
