[0019] 1, maintenance hook load-bearing steel beam, 2, load-bearing beam reinforcing plate. DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] WITH REFERENCE Figs. 1-2 to the drawings, the utility model provides an embodiment: a novel hidden maintenance hook, including maintenance hook load-bearing steel beam 1 and load-bearing beam reinforcing plate 2, maintenance hook load-bearing steel beam 1 is H-shaped steel, I-beam or channel steel cross section, has higher load-bearing performance and bending strength, ensures that when using, can stably bear the load of hanging. The web middle position of maintenance hook load-bearing steel beam 1 is prefabricated or set in later period maintenance hook hole, the design diameter of the hole is not more than one third of the height of steel beam, to effectively control the weakening of the overall strength of steel beam, meet the fixing demand of maintenance equipment simultaneously, improve the practicability of hook.

[0022] The load-bearing beam stiffener 2 is arranged around the hole as a reinforcing measure, has a ring structure, is tightly welded with the hole periphery, can significantly improve the local carrying capacity of the steel beam web, prevent local failure caused by concentrated load, and enhance the overall safety. In order to ensure safety and structural stability, the position of the maintenance hook hole avoids the beam end or the area with larger stress of the steel beam. This arrangement method can reduce the weakening risk of the key stress area of the steel beam caused by the opening, and maximize the overall stiffness and strength of the steel beam.

[0023] The load-bearing beam stiffener 2 is tightly welded with the maintenance hook hole periphery, which can form a stable structural unit, so that the stress distribution of the maintenance hook when bearing the hanging force is more uniform, thereby avoiding the structure crack or failure caused by local stress concentration. The maintenance hook load-bearing steel beam 1 and the load-bearing beam stiffener 2 are made of high-strength steel, which can provide excellent tensile and shear resistance, ensuring the long-term safe operation of the hook and its supporting components. Further, the spacing of the maintenance holes on the same beam is not less than one-fourth of the height of the steel beam. This design can effectively avoid the problem of local strength weakening caused by too concentrated maintenance holes, and improve the reliability and service life of the overall structure of the steel beam.

[0024] Working principle: First, the maintenance hook load-bearing steel beam 1 is used as the load-bearing main body of the maintenance hook, and adopts H-shaped steel, I-shaped steel or channel steel section. These section forms of steel beams have excellent carrying capacity and bending strength, which can ensure that they can bear large load without deformation or damage during the operation of the hanging equipment. In the middle position of the steel beam web, maintenance hook holes are arranged according to the specific maintenance requirements, and the diameter of the hole is controlled within one-third of the height of the steel beam. This diameter design can not only meet the installation requirements of the hook, but also effectively reduce the weakening of the overall structural strength of the steel beam caused by the hole.

[0025] Secondly, the load-bearing beam stiffener 2 is arranged around the maintenance hook hole as a key reinforcing measure. The load-bearing beam stiffener 2 adopts a ring structure, the material is consistent with the steel beam, and is connected with the steel beam by tight welding. This ring-shaped reinforcing design can significantly improve the carrying capacity of the steel material around the hole and optimize the stress distribution, thereby preventing the local area from failing due to concentrated load. The role of this stiffener is particularly important, as it not only compensates for the local strength weakening caused by the opening, but also improves the structural stability of the entire steel beam.

[0026] In addition, the specific position of the maintenance hook hole is precisely arranged to avoid the beam end and the area with larger stress of the steel beam. This design concept effectively avoids the weakening of the key stress part while maintaining the overall stiffness and stress balance of the steel beam. The spacing between multiple maintenance holes on the same beam is also controlled to be more than one-fourth of the height of the steel beam, so as to ensure that the distribution of the maintenance holes will not adversely affect the overall structure of the steel beam.

[0027] It should be pointed out finally that: the above only for the preferred embodiments of the utility model have, and do not for limiting the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or make equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principle of the utility model, should be included in the protection scope of the utility model.
