Abstract
The utility model discloses a big bandwidth bearing roller crossbeam, including ground sole (1), crossbeam body (2), crossbeam body (2) are rectangular pipe (3), rectangular pipe (3) fixed connection is on ground sole (1) upper portion, rectangular pipe (3) upper portion fixed connection limit pillar (4), well pillar (5). The utility model provides a big bandwidth bearing roller crossbeam adopts the rectangular pipe to replace the angle steel as the bearing roller crossbeam, when the same every meter weight, and the width of rectangular pipe and highly bigger, rigidity and intensity are better, because the rectangular pipe is high bigger than the angle steel, the corresponding height that has reduced well pillar and limit pillar has improved its rigidity, add the bracing band steel between both sides limit pillar and rectangular pipe crossbeam, further improved the rigidity and the intensity of limit pillar, oblique angle and with shrouding closure is fallen at rectangular pipe crossbeam both ends, prevents to advance in the rectangular pipe ash or dust pollution and the corrosion.
Description
Technical field
The utility model relates to the technical field of a large bandwidth, the greatly belt conveyer of operational throughput, specifically a kind of large bandwidth carrying roller crossbeam using rectangular tube structure.
Background technology
Along with the development of technology, the Application of large bandwidth, large operational throughput is more and more general.The DTII(A edited by Beijing handling machinery research institute and Wuhan Feng Fan scientific and technological development limited liability company) bandwidth 500 to the 1400mm of original general fixed belt conveyer expands to 500 to 2400mm by design of belt conveyor handbook (the 2nd edition).Idler machining beam structure in bandwidth 1600 to 2400mm scope has still followed little bandwidth structure, and this exists following problem:
One to be mounted in the base anchor span of the left and right sides on middle frame larger, and when every meter of weight on an equal basis, the rigidity of angle steel crossbeam is relative with intensity poorer.Two is that zone face height is larger, and the height of corresponding edge pillar and B-C post adds, and requires higher to the strength and stiffness of B-C post and quarter line pillaring.The operational throughput of three large bandwidth belt conveyers own is just larger many, the corresponding gravity be applied on carrying roller crossbeam, and because rubbing and pressing the impulsive force along service direction falling into resistance generation to increase considerably, the requirement of the strength and stiffness to large bandwidth carrying roller crossbeam can be strengthened.Therefore, how to design a kind of large bandwidth carrying roller crossbeam rational in infrastructure and become the problem needing solution badly.
Summary of the invention
For now at present Problems existing and deficiency, provide a kind of large bandwidth carrying roller crossbeam, concrete technical scheme is as follows:
A kind of large bandwidth carrying roller crossbeam, comprise base anchor 1, cross-beam body 2, described cross-beam body 2 is rectangular tube 3, and described rectangular tube 3 is fixedly connected on base anchor 1 top, and described rectangular tube 3 top is fixedly connected with quarter line pillaring 4, B-C post 5.
Alternately, above-mentioned a kind of large bandwidth carrying roller crossbeam, also comprises diagonal brace band steel 6, and described diagonal brace band steel 6 one end is welded on rectangular tube 3, and the other end is welded on quarter line pillaring 4, and two diagonal brace band steels 6 are symmetrical arranged.
Alternately, above-mentioned a kind of large bandwidth carrying roller crossbeam, described rectangular tube 3 two ends are set to oblique angle structure.
Alternately, above-mentioned a kind of large bandwidth carrying roller crossbeam, described rectangular tube 3 two ends use shrouding 7 to close.
Alternately, above-mentioned a kind of large bandwidth carrying roller crossbeam, the side roller 8 of both sides snaps in the flat side's breach on B-C post 5 and quarter line pillaring 4; Middle idler roller 9 snaps in the flat side's breach on B-C post 5, forms a complete groove profile carrier roller group.
Alternately, above-mentioned a kind of large bandwidth carrying roller crossbeam, described rectangular tube 3 is fixedly connected on base anchor 1 top in a welding manner, and described rectangular tube 3 top is fixedly connected with quarter line pillaring 4, B-C post 5 in a welding manner.
Alternately, above-mentioned a kind of large bandwidth carrying roller crossbeam, two quarter line pillarings 4 are symmetrical arranged, and two B-C posts 5 are symmetrical arranged.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
The first, the utility model proposes and adopt rectangular tube to replace angle steel as carrying roller crossbeam, when identical every meter of weight, the width of rectangular tube and highly more greatly, rigidity and intensity better.
The second, the aspect ratio angle steel due to rectangular tube is large, correspondingly reduces the height of B-C post and quarter line pillaring, improves its rigidity.
Three, for improving rigidity and the intensity of quarter line pillaring further, between dual-side pillar and rectangular tube crossbeam, having added diagonal brace band steel, further increased rigidity and the intensity of quarter line pillaring.
Four, bevelling, rectangular tube crossbeam two ends closing with shrouding, prevents from entering in rectangular tube ash or dust pollution and corrosion.

Reference numeral: 1 be base anchor, 2 be cross-beam body, 3 be rectangular tube, 4 be quarter line pillaring, 5 be B-C post, 6 be diagonal brace band steel, 7 be shrouding, 8 be side roller, 9 for middle idler roller.
Detailed description of the invention
All features disclosed in this specification sheets, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
As shown in Figure 1 and Figure 2, in conventional confguration, the cross-beam body of large bandwidth carrying roller crossbeam adopts angle steel to be welded, the rigidity of this heavy angle steel crossbeam is relative with intensity poor, also add the height of quarter line pillaring and B-C post simultaneously, largely can reduce rigidity, the intensity of quarter line pillaring and B-C post while the height of quarter line pillaring and B-C post increases.
As shown in Figure 3, Figure 4, the utility model provides a kind of large bandwidth carrying roller crossbeam, comprises base anchor 1, cross-beam body 2, and described cross-beam body 2 is rectangular tube 3, described rectangular tube 3 is fixedly connected on base anchor 1 top, and described rectangular tube 3 top is fixedly connected with quarter line pillaring 4, B-C post 5.Described rectangular tube 3 is fixedly connected on base anchor 1 top in a welding manner, and described rectangular tube 3 top is fixedly connected with quarter line pillaring 4, B-C post 5 in a welding manner.Certainly, also can be fixedly connected with by other connection mode, such as, being fixedly connected with by fastener.Two quarter line pillarings 4 are symmetrical arranged, and described two B-C posts 5 are symmetrical arranged.
Described large bandwidth carrying roller crossbeam also comprises diagonal brace band steel 6, and described diagonal brace band steel 6 one end is welded on rectangular tube 3, and the other end is welded on quarter line pillaring 4.The diagonal brace band steel 6 arranged can increase the rigidity of crossbeam and quarter line pillaring 4 from large bandwidth carrying roller crossbeam inside.The quantity of described diagonal brace band steel 6 can set according to actual needs.If the quantity of diagonal brace band steel 6 is two, then described two diagonal brace band steels 6 are symmetrical arranged.
