Embodiment Construction

[0032] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0033] As a first aspect of the present invention, a suspension beam for a railway crane is provided. Such as Figure 1 to Figure 12 As shown, the hanging beam includes a beam body 10 and lifting lugs 20 . There are two lifting lugs 20 . Since the lifting lugs 20 are movably connected with the beam body 10, the span between the two lifting lugs 20 will be adaptively adjusted according to the span of the lifting object during the lifting operation, so that the lifting beam can meet the needs of different sizes. According to the requirement of hoisting heavy objects, the stress concentration at the junction of the beam body 10 and the lifting lug 20 is avoided, and the structural damage of the hanging beam is avoided, thereby improving the reliabilit...

Abstract

The invention provides a lifting beam for a railway crane and the railway crane. The lifting beam comprises a beam body and two lifting lugs, wherein the two lifting lugs correspond to the two ends of the beam body one to one, and are movably connected with the beam body. According to the lifting beam and the railway crane, the lifting lugs are movably connected with the beam body, and the span between the two lifting lugs can be adaptively regulated according to the span of a lifted object during lifting operation, so that the using requirements of lifted objects with different sizes on the lifting beam can be met, stress concentration at joints of the beam body and the lifting lugs is avoided, damage to the structure of the lifting beam is avoided, and the operational reliability of the lifting beam is further improved; in addition, the lifting beam has the characteristics of simple structure and low manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of railway cranes, in particular to a suspension beam for a railway crane and the railway crane. Background technique [0002] Railway cranes, such as telescopic boom railway rescue cranes, are mainly used for the rescue of railway rolling stock derailment, overturning and other traffic accidents, and are one of the basic equipment to ensure fast and smooth railway transportation. The railway accident rescue spreader is an important part to ensure that the railway crane can carry out the rescue work conveniently and quickly. TB / T3123.1-2005 "Railway Traffic Accident Rescue Equipment - Part 1 - Spreader" stipulates the type, performance parameters and technical requirements of the railway traffic accident rescue spreader. [0003] A suspension beam used for a railway crane in the prior art includes a beam body and lifting lugs, and the lifting lugs are fixedly arranged on the beam body. Since the lifting lu...
