Problems solved by technology

However, this method needs to add a suitable independent oil cylinder and install it under the turntable of the crane, and there are also requirements for the road surface where the oil cylinder base is placed, that is, it is flat and the foundation has sufficient strength. It retracts and turns to be placed horizontally so that it will not affect the rotation of the turntable or collide with other things around it, and the operation is relatively cumbersome

Embodiment Construction

[0022] Now further illustrate how the present invention is implemented in conjunction with accompanying drawings:

[0023] The curved beam 5 of the curved beam leveling device T in this design is composed of a lower bottom plate 5-1 and an upper curved plate, and the upper curved plate is composed of two parallel curved plates 5-2, and the curved plate 5-2 The outer cylindrical surface of each arc-shaped plate faces upwards, and a sliding shoe 2 is arranged on the left and right sides above each arc-shaped plate. The outer cylindrical surface of -2 fits and can slide along it. The double extension rod oil cylinder 4 is arranged in parallel between the two arc-shaped plates 5-2, and the short shafts 4-1 on both sides of the cylinder are installed in the corresponding recesses of the arc-shaped plates respectively. In the groove 5-3, the groove opening is closed with clamps and bolts. The axis direction of the minor axis is perpendicular to the axis direction of the cylinder. Th...

Abstract

The invention provides a railway crane with outer rail superelevation levelling function and belongs to the crane field. The crane realizes levelling by arranging an arched beam levelling device between an upper vehicle frame and a lower steering frame. The device pushes the vehicle frame by a piston rod base matched with a double-boom oil cylinder such that the vehicle frame relatively slides along an arched beam matched therewith through skid shoes so as to gradually reduce the inclination degree of the vehicle frame above the arched beam to realize levelling; synchronously, as the double-boom oil cylinder can rotate with certain angle around the short shafts at the two sides of a cylinder with respect to the arched beam and the arched beam base plate can also slightly rotate with respect to the steering frame, the vehicle frame and the upper components can be levelled to be horizontal even though the arched beam and the steering frame connected to the lower portion of the arched beam are inclined. The invention solves the problem that the crane integrally inclines when the crane works at a railway curve by an integrated levelling device and ensures the rated hoisting performance and working safety when the crane works at a railway curve.

Description

technical field [0001] The invention relates to a railway crane with an outer rail super-high leveling function, which belongs to the field of cranes. Background technique [0002] Railway cranes are mainly used for railway rescue, and are also suitable for loading and unloading of large cargo, equipment installation, railway construction, laying rail rows, replacing turnouts, erecting bridges and other engineering operations. [0003] When the railway crane is working on the curve, the whole crane is in a tilted state due to the super high outer rail, which not only makes the crane overturn easily and cannot reach the rated lifting capacity, but also may It will cause part of the outline of the crane to exceed the prescribed railway rolling stock limit, which will affect the operation of adjacent line vehicles and bring great safety hazards. Therefore, it is necessary to adjust the inclined crane to a level state in order to guarantee its rated lifting capacity and keep it...
