Abstract
The invention relates to a flexible suspension lifter of crane, wherein it is formed by a left flexible beam, middle beam and right flexible beam, while the left and right beams are at two sides of middle beam, supported by the upper and lower support wheels on the middle beam; two sides of middle beam are symmetry fixed with transmitters, connected to the flexible drawing rods; the drawing rods are connected to the flexible beams; the left and right flexible beams are connected with magnetic discs. The invention can fully utilize space with high efficiency.
Description
Technical field
The invention belongs to the parts of hoisting crane, relate to a kind of flexible beam type suspender that hoisting crane makes full use of the factory building space of being convenient to.
Background technology
Along with the fast development of modern metallurgical industry, the not only more and more large-scale change of the specification of single steel plate (grow to 52000mm most, the wideest to 5300mm, be as thin as 5mm), and output is big, and specification is many.The suspender of handling steel plate is also changing.With many long steel plates of crane combined lifting, can not rationally utilize the space in the past.The steel plate of many specifications will be stacked in the limited space of factory building, how rationally to utilize the space just to become to improve the outstanding problem of stacking efficient.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of crane telescopic suspended beam sling is provided, have and rationally utilize factory building stacking space, small investment, income is big, handling efficient advantages of higher.
The present invention is achieved through the following technical solutions:
A kind of crane telescopic suspended beam sling, comprise lifting beam and the disk that is fixed on the lifting beam, described lifting beam is a kind of by left telescopic girder, intermediate beam, the telescopic hanging beam that right telescopic girder constitutes, left and right sides telescopic girder is separately positioned on the both sides of intermediate beam, by the upper support wheel, the supporting of lower support wheel that are fixed on the intermediate beam, the both sides of intermediate beam are symmetrically fixed with transmission device, and two sets of transmission mechanism connect telescopic lever respectively, telescopic lever connects telescopic girder, is connected with disk on the telescopic girder of the left and right sides.
The inboard of described left telescopic girder, right telescopic girder respectively and track adjusting wheel is housed between the intermediate beam.On the described intermediate beam, be provided with mechanical position limitation and electric limit switch with the end position of left telescopic girder, right telescopic girder.Described transmission device is provided with the moment of torsion safety pin.
The present invention compared with prior art has the following advantages and beneficial effect:
Because drop in beam is when stretching out state, but the long steel plate of handling, and during retracted mode, but the short steel plate of handling is piled short slab with retracted mode during little space, piles long slab with stretching out state during large space, so can reach the purpose that makes full use of the space.Flexible short drop in beam adopts mechanical-stretching, by motor-driven, be with about telescopic girder and moving, so drop in beam length can change.But same drop in beam be the long steel plate of handling both, but the also short steel plate of handling has saved the link of changing drop in beam, has saved the time, handling efficient height.The setting of telescopic hanging beam can solve the problem of Metallurgical Factory's steel plate warehouse for finished product workshop stacking insufficient space, small investment, and income is big.
Along with the development of world economy, the economy of China was being advanced by leaps and bounds in recent years, especially after 2000, and the economic total volume steady-state growth.Be representativeness with the Ferrous Metallurgy industrial development especially wherein, the iron and steel output of China ranks first in the world.The production facilities that the development need of steel and iron industry is a large amount of, wherein the hoisting crane material handling equipment that is absolutely necessary.So telescopic suspended beam sling development prospect of the present invention is wide.
Description of drawings:
Fig. 1 is a kind of structural representation of crane telescopic suspended beam sling;
Fig. 2 is that the A of Fig. 1 is to view.
Below in conjunction with accompanying drawing and by preferred embodiment, the present invention is further illustrated.
The specific embodiment
As shown in Figure 1, 2, a kind of crane telescopic suspended beam sling is made up of metal construction, mechanical drive, disk three parts.Metal construction is divided into three parts: left telescopic girder 1, intermediate beam 2, right telescopic girder 3.Wherein disk 4 is fixed on the metal construction.Two sets of transmission mechanism 8 are separately fixed at the both sides of intermediate beam 2, and connect telescopic lever 7 respectively, and telescopic lever 7 connects telescopic girder.Left and right sides telescopic girder is separately positioned on the both sides of intermediate beam, and by the upper support wheel 5,6 supportings of lower support wheel that are fixed on the intermediate beam, there are track adjusting wheel 9 guiding the inboard.When flexible, the motor-driven telescopic lever is realized the variable in distance between intermediate beam and the telescopic girder.The telescopic girder two ends all are equipped with mechanical position limitation 10, electric spacing 11, in case drop in beam stretches out outside the beam.Simultaneously, in transmission link, increase by place's moment of torsion safety pin 12.When telescopic girder and intermediate beam were stuck, motor was still at output torque, and when torque during greater than setting value, the action of moment of torsion safety pin, messenger chain interrupts, and has protected motor, retarder parts.
According to flexible scope, left telescopic girder 1, the disk 4 that right telescopic girder 3 hangs can be one or more.
Obviously; those skilled in the art can change and is out of shape the present invention; if these changes and distortion do not break away from principle of the present invention, belong to the scope of claim of the present invention and equivalent technologies thereof, then protection scope of the present invention also comprises these changes and is out of shape interior.
