The utility model discloses a novel combined lifting lug, which comprises two lifting lug plates and a lifting lug shaft. The plate is divided into the upper part and the lower part. The upper part has a round hole in the center, and the lower part is the fixed part of the lifting lug installation equipment; the lifting lug shaft is a hollow structure in the shape of a round shaft; The hollow structure of the trunnion shaft is interference fit. The one weld used in the traditional lifting lug is changed to two welds, which increases the welding area between the lifting lug and the equipment, improves the connection strength between the lifting lug and the equipment, and reduces the cost in equipment manufacturing, installation, use and maintenance. The amount of deformation of the ear when moving. The device has the advantages of low cost, simple overall structure, convenient manufacture, and high structural strength. It uses non-standard lifting lugs without changing the shape and size of the lifting lugs. It is suitable for equipment that allows welding of lifting lugs and is easy to popularize.

Description

A new type of combined lifting lug

technical field

The utility model belongs to lifting lug components, in particular to a novel combined lifting lug.

Background technique

Lifting lug refers to the lifting point structure installed on the equipment or other hanging objects for lifting, which has a wide range of uses, especially plays a very important role in the manufacture, installation, use and movement of equipment. The welding area between the traditional lifting lug and the equipment is small, the lifting lug is easy to deform, and the space between the lifting lug and the lifting rope is easy to wear. During the lifting process, not only accidents and property losses are likely to occur, but also seriously threaten the safety of workers.

Utility model content

In order to solve the above-mentioned problems existing in the existing lifting lug, the utility model provides a novel combined lifting lug.

The technical solutions adopted are:

A new type of combined lug, including two lug plates, a lug shaft, the lug plates are arranged on the left and right, the lug shaft is in the middle, and the left and right lug plates are fixedly connected to the lug shaft; the left and right lug plates are divided into The upper part and the lower part, the central part of the upper part is provided with a round hole, and the lower part is the fixing part of the lifting lug; the lifting lug shaft is a hollow structure in the shape of a round shaft, and the round holes of the left and right lifting lug plates are connected with the hollow structure. surplus cooperation. This combination method changes the traditional lifting lug from one welding seam to two welding seams, which increases the welding area between the lifting lug and the equipment, improves the connection strength between the lifting lug and the equipment, and reduces the cost in equipment manufacturing, The amount of deformation of the lifting lug during installation, use and movement.

The inner diameter of the hollow structure of the lug shaft is consistent with the diameter of the round hole of the lug plate.

The shape of the lug plate is trapezoidal.

The upper edge of the lug plate is arc-shaped.

The shape of the lifting lug has advantages in saving materials. According to actual needs, the shape of the lifting lug plate can be changed, and both rectangle and square are acceptable, which is still more advantageous than the previous single-piece lifting lug.

The utility model has beneficial effects: the combination of two lug plates and one lug shaft is adopted, and the suspension rope is fixed through the middle suspension lug shaft, without taking protective measures, and the mutual wear between the suspension rope and the suspension lug can be directly avoided The damage to the sling improves the safety factor. According to the finite element analysis, under the same working conditions (the hoisting weight, hoisting position, hoisting angle, and the number of lifting lugs are all the same), the strength of the structure is twice as high as that of the single-wall lifting lugs, which ensures that when lifting heavy objects It has the advantages of high safety and stability, allowing the fatigue times of hoisting to be greatly increased, the overall structure is simple, and the structural strength is high. This structure uses non-standard lifting lugs without changing the shape and size of the lifting lugs. It is suitable for equipment that allows welding of lifting lugs, such as storage tanks in the pressure vessel industry, station bottle sets and other equipment, and is easy to promote.

Detailed ways

The utility model is described in detail below in conjunction with accompanying drawing

As shown in Figure 1, a new type of combined lug includes two lug plates 1, a lug shaft 2, the lug plate 1 is arranged left and right, the middle is the lug shaft 2, the lug plate 1 and the lug shaft 2 It is connected by welding; the lifting lug plate 1 is divided into an upper half and a lower half, as shown in Figure 2, a round hole 3 is provided in the center of the upper half, and the lifting lug shaft 2 is a circular shaft-shaped hollow structure. The hole 3 of the plate is interference fit with the hollow structure of the lug shaft, the inner diameter of the hollow structure of the lug shaft 2 is consistent with the diameter of the hole 3 of the lug plate, the shape of the lug plate 1 is trapezoidal, and the upper edge of the lug plate 1 is a circular arc shape. The lifting rope is fixed by the lifting lug shaft 2 in the middle, which avoids the mutual wear between the lifting rope and the lifting lug. The lower half of the left and right lifting lug plates 1 are installed with fixed parts of the equipment and welded with the equipment to increase the welding area and ensure the connection strength.

Force analysis and comparison of traditional single plate lifting lugs and combined lifting lugs:

(Note: The data in the above table is when the weight of the hoisting equipment is 14 tons, the hoisting angle is 45°, and the 4 lifting lugs are hoisted at the same time)

Although, the utility model has been described in detail with the general description and the specific embodiment above, but on the basis of the utility model, some modifications or improvements can be made to it, which will be obvious to those skilled in the art . Therefore, the modifications or improvements made on the basis of not departing from the spirit of the utility model all belong to the protection scope of the utility model.
