A transition beam suitable for lifting slings for large objects

Abstract

The invention belongs to the technical field of intelligent hoisting and particularly relates to a transition beam for a sling suitable for hoisting large objects. In the current intelligent hoistingtechnological field, the sling plays an important role, the transition beam serves as a key part of the sling, and safe operation of the current intelligent hoisting technology is guaranteed. The structures of lateral lifting lugs serving as key parts for bearing the sling in the transition beam are subjected to optimal design, and the bearing stability is guaranteed through dual actions of welding and mechanical connection; upper connecting pieces of the lateral lifting lugs can be connected with limiting holes in a clamped manner, an upper reinforcing plate can further play a pressing role on the upper connecting pieces, and the role of secondary fixing is achieved; and lower connecting pieces stretch into inserting holes to play bottom supporting and transverse stabilizing roles, and alower reinforcing plate further plays a supporting role on the lower connecting pieces. Through a series of the above structural optimization, the transition beam for the sling can meet the hoisting requirements for the large objects which are large in weight and size through strict calculation, type selection and load testing.

Description

technical field [0001] The invention belongs to the technical field of intelligent hoisting, relates to a sling accessory for logistics, transportation and construction, and in particular to a transition beam suitable for a sling used for hoisting large objects. Background technique [0002] The sling, the connection between the main body of the hoist or the hoisted object and the hoisted object is also a general term covering slings and slings. According to the specific use, the slings mainly include wire rope slings, chain slings, hook slings and so on. For the hoisting of large objects, the structure of the sling mainly includes a transition beam, a sling and a hook, wherein the transition beam is connected to the upper crane with its own sling, and the lower part is connected to several slings; each sling The other end of each is linked with a suspension hook, and the suspension hook is used for hooking the outer periphery of the large price. However, large objects are...

Problems solved by technology

[0004] The parts in the transition beam of the above-mentioned patent are still only combined by welding, wherein the lower lifting lug that plays a connecting and supporting force for the sling is made of two metal plates (the long plate of the lower lifting lug and the lower hanging lug). The upper, lower and inner side of the lower lifting lug are combined with other parts by welding. This kind of structure requires extremely high welding technology, otherwise the risk of solder joint breakage will easily occur, which determines that it cannot Meet heavy lifting
