Abstract
The invention discloses an equalizing beam structure of a crane. The equalizing beam structure is characterized by comprising a large equalizing beam, two intermediate equalizing beams and two small equalizing beams, wherein the center of the large equalizing beam is installed on a main beam, the two intermediate equalizing beams are correspondingly installed on two ends of the large equalizing beam, and travelling wheel groups are installed on the bottoms of the two intermediate equalizing beams; the centers of the two small equalizing beams are installed on the intermediate corresponding equalizing beams, and another travelling wheel groups are installed on two ends of each small equalizing beam. The equalizing beam structure disclosed by the invention is additionally provided with the intermediate equalizing beams, thereby having the advantages of large bearing capacity and good equalizing effect.
Description
Technical field
The present invention relates to a kind of hoisting crane, relate in particular to a kind of hoisting crane equalizing bar structure.
Background technology
Hoisting crane belongs to a kind of of elevator machinery, be a kind ofly circulate, the machinery of intermittent moment.A working cycle comprises: load-engaging device is mentioned article from getting thing ground, is moved horizontally to the appointed place then and falls article, then carries out counter motion, makes the load-engaging device reposition, in order to circulate next time.
There is the shortcoming that bearing capacity is little, beam body pressure big, the requirement of track straightness accuracy is high and easily gnaw rail in the equalizing bar of the traveling gear of the traditional hoisting crane two little one big structures that adopt more.
Summary of the invention
The object of the present invention is to provide a kind of hoisting crane equalizing bar structure, it has the big and balance good effectiveness of bearing capacity, to solve the problem that the crane travelling gear equalizing bar exists in the prior art.
For reaching this purpose, the present invention by the following technical solutions:
A kind of hoisting crane equalizing bar structure, it comprises big equalizing bar, two intermediate equilibria beams and two little equalizing bars, the center of described big equalizing bar is installed on the girder, described two intermediate equilibria beam correspondences are installed on the two ends of big equalizing bar, and the walking wheels are installed in the bottom of described two intermediate equilibria beams, the center of described two little equalizing bars is installed on the intermediate equilibria beam, and the walking wheels are all installed at the two ends of described two little equalizing bars.
Especially, described big equalizing bar, intermediate equilibria beam and little equalizing bar are all installed by bearing pin, axis plate and adjustment plate.
Especially, described intermediate equilibria beam comprises connecting portion and beam body, is connected with big equalizing bar and little equalizing bar on the described connecting portion, and described beam body skew back below in the big equalizing bar is extended its end walking wheels are installed.
Beneficial effect of the present invention is that compared with prior art described hoisting crane equalizing bar structure is set up the intermediate equilibria beam, has bearing capacity greatly and the advantage of good balance effect.
Description of drawings
Fig. 1 is the structural representation of the hoisting crane equalizing bar structure that provides of the specific embodiment of the invention 1;
Fig. 2 is the scheme of installation of the intermediate equilibria beam of the hoisting crane equalizing bar structure that provides of the specific embodiment of the invention 1.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
See also illustrated in figures 1 and 2, in the present embodiment, a kind of hoisting crane equalizing bar structure comprises big equalizing bar 1, the center of described big equalizing bar 1 is installed on an end of girder 2, and the two ends of described big equalizing bar 1 are symmetrically installed with intermediate equilibria beam 3, described intermediate equilibria beam 3 comprises connecting portion 4 and beam body 5, connect big equalizing bar 1 on the described connecting portion 4, described beam body 5 extends its end to big equalizing bar 1 interior skew back below walking wheels is installed, the center of two little equalizing bars 6 is installed on the connecting portion 4 of intermediate equilibria beam 3, and the walking wheels are all installed at the two ends of described two little equalizing bars 6.
Described intermediate equilibria beam 3 is installed on the big equalizing bar 1 by bearing pin 7, axis plate 8 and adjustment plate 9, and the mounting structure of described big equalizing bar 1 and little equalizing bar 6 and the mounting structure of intermediate equilibria beam 3 are basic identical.
Above embodiment has just set forth groundwork of the present invention and characteristic; the present invention is not limited by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
