Description

Technical Field

[0001] This utility model belongs to the technical field of steel plate hoisting auxiliary equipment, and specifically relates to a steel plate hoisting tool. Background Technology

[0002] Flat steel (referred to as steel plate) is widely used in the machinery manufacturing industry due to its excellent mechanical properties and processing characteristics. With industrial development and technological progress, the demand for steel plates is not only reflected in quantity but also in higher requirements for size and weight. Especially during processing and production, the transfer of steel plates has become a critical link. For steel plates with large lengths or heavy weights, traditional handling methods are insufficient to meet practical needs, thus requiring specially designed lifting tools.

[0003] Currently, commonly used lifting tools on the market primarily achieve steel plate lifting operations through a support structure connected to the lifting equipment. These support structures can be rod-type or frame-type structures, with suspended hooks installed at their lower parts. However, in practical applications, it has been found that this design has certain limitations. For example, during the lifting process, if the strength of the support structure is insufficient to withstand the weight of the steel plate, it may lead to damage to the support structure, resulting in a safety accident. Furthermore, the installation position of the hooks on existing lifting tools is usually fixed, which limits their applicability to lifting steel plates of specific sizes, failing to flexibly address the lifting needs of steel plates of different sizes. This not only reduces work efficiency but also increases operational difficulty and safety risks. Utility Model Content

[0004] In view of the shortcomings of existing technologies, a steel plate lifting tool is proposed to solve the technical problems of low support structure strength that is easily damaged and fixed hook installation position that cannot meet the lifting needs of steel plates of different sizes.

[0007] The technical solution is further configured such that the upper lifting ear plate is provided with an upper lifting hole, and the upper lifting hole is configured as an elliptical hole.

[0008] The technical solution is further configured such that the first end of the side-mounted ear plate is connected to the support plate, and its second end extends away from the support plate and extends to the outside of the support beam.

[0009] The technical solution is further configured such that the second end of the side-mounted ear plate is configured as a structure that is narrow at the top and wide at the bottom, and a side-mounted hole is provided at the bottom of the second end.

[0010] The technical solution is further configured such that a lifting ring is provided at the side lifting hole, the lifting ring is locked by bolts and nuts, and the lifting ring is connected to the steel plate clamp by a wire rope.

Figures 1 to 4 The system includes a supporting beam 100, with an upper lifting lug 200 above the supporting beam 100. The upper lifting lug 200 is connected to a lifting device. Side lifting lugs 300 are symmetrically arranged on the sides of the supporting beam 100. The side lifting lugs 300 are connected to steel plate clamps, which are used to hold the steel plates to be lifted. Several side lifting lugs 300 are arranged along the length of the supporting beam 100, and a fixing plate 400 connects adjacent side lifting lugs 300.

[0018] Furthermore, several side-mounted ear plates 300 are arranged at equal intervals, and the side-mounted ear plates 300 located on both sides of the supporting crossbeam 100 are arranged symmetrically.

[0019] Furthermore, steel plate clamps are a mature existing technology, and their structure can be referenced in CN208732457U, an L-shaped steel plate clamp with a self-locking function.

[0020] By setting up several side lifting lugs 300, the appropriate position of the side lifting lugs 300 can be selected and connected to the steel plate clamp according to the size of the steel plate to be lifted, so as to carry out the lifting operation of the steel plate to be lifted, thereby improving flexibility; by setting up the fixing plate 400, the stability of the side lifting lugs 300 and the supporting beam 100 is enhanced, thereby improving the overall strength.
