Description

Technical Field

[0001] The utility model relates to the technical field of steel structure and steel component hoisting, and in particular to a lifting eye reinforcement device for a steel structure. Background Art

[0002] Steel structure hoisting is a common task in construction, electromechanical, and marine engineering, and the lifting lug is an important part of steel structure hoisting. In steel structure hoisting, the lifting lug is usually welded to the steel structure being hoisted as an important component connecting the sling and the steel structure. When hoisting a large steel structure, four lifting points are generally arranged. Since the spacing between the lifting points is larger than the spacing between the hooks, the sling and the plumb line usually present a certain angle. Due to the limitations of the lifting equipment and the form of the lifting lug, the lifting lug is subjected to oblique tension. The larger the angle and the heavier the steel structure, the greater the oblique tension of the lifting lug. This situation can easily cause deformation of the lifting lug and cracking of the weld. In severe cases, it can cause the lifting lug to fall off and hoisting accidents to occur. Whether the lifting lug is firm or not has become an important issue of concern in hoisting. Therefore, it is very important to reinforce the lifting lug of the steel structure and improve the anti-oblique tension strength of the lifting lug to ensure the hoisting operation.

[0003] After the steel structure lifting lugs are installed, they cannot be modified. If the lifting lugs are subjected to large diagonal tension, they need to be reinforced. The existing methods of adding toggle plates, increasing the lifting height, and using balance beams are, firstly, cumbersome to operate, heavy in structure, and ineffective; secondly, the design and production cycle is long, the cost is high, and the applicability is poor. In summary, it is necessary to invent a reinforcement device that is easy to install and use, widely applicable, and small in weight and volume. Utility Model Content

[0020] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0023] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the utility model. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0024] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.

[0025] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0026] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
