Abstract
A crane girder with corrugated webs relates to the field of cranes. The cross section of the girder is formed by integrating two webs, an upper flange and a lower flange, the upper flange is parallel to the lower flange, the flat webs are arranged near supports close to two ends of a crane, the double webs are disposed between the upper flange and the lower flange, and the double webs are disposed in symmetry and in a honeycomb structure. The crane girder has the advantages that the webs include the corrugated webs and the flat webs so that the crane girder is fine in shear resistance and fatigue resistance, higher structural rigidity and better economy are achieved for the crane girder with hosting capacity of 50 tons and below and a height below 2000, and manufacture of pre-arch is easier. The crane girder is capable of substituting common welded box type steel girders with flat webs, and is wider in usage as compared with the common welded box type steel girders.
Description
Technical field
The utility model relates to the elevator machinery field, is specifically related to a kind of corrugated web hoisting crane crossbeam.
Background technology
Hoisting crane has irreplaceable effect as the major equipment of material handling in the big production of modernization, strengthen the research of hoisting crane and the material handling level of improving improving China are had great importance.The crane in bridge type that China is widely used in industries such as machinery, metallurgy, transportation has at present accounted for about 40% of China's hoisting crane.The crane span structure of crane in bridge type is a kind of mobile metal construction, it is main load-carrying element, it is bearing the wheel load effect of fully loaded crane carriage on the one hand, it is by the cart operation wheel of supporting crane span structure on the other hand, the total weight of fully loaded hoisting crane has been passed to factory building track and building structure, and the weight of crane span structure generally accounts for more than 60% of hoisting crane deadweight.Box girder is one of base model of crane in bridge type metal crane span structure, and the crane safety coefficient of common box girder structure is big, and consumption of raw material is many, and structure is reasonable inadequately, and efficient is low, can not well adapt to the big needs of producing of modernization.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of have good shearing resistance, fatigue performance, has the better rigidity of structure and good and economic, and it makes the corrugated web hoisting crane crossbeam of the easier realization of pre-arch camber.
Technical problem to be solved in the utility model realizes by the following technical solutions,
Corrugated web hoisting crane crossbeam, its section degree of lip-rounding is made of two blocks of webs and top flange, lower flange disjunctor, top flange and lower flange be arranged in parallel, it is characterized in that: described near adopting flat web near the bearing at hoisting crane two ends, two webs are set between described top flange and lower flange, two web symmetries are placed, and are cellular structure.
Adopt the single face fillet weld to be connected between the described pair of web and top flange, the lower flange.
Described pair of web is corrugated web.
The beneficial effects of the utility model are: because web adopts corrugated web peace web to combine, make it have good shearing resistance, fatigue performance, for the hoisting crane crossbeam of load-carrying ability below 50 tons and 50 tons, the height 2000 with interior, have the better rigidity of structure and good and economic, and it makes the easier realization of pre-arch camber, and this product can replace the welding box steel beam of common flat web, and more extensive than purposes.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, corrugated web hoisting crane crossbeam, its section degree of lip-rounding is made of two blocks of webs and top flange 2, lower flange 3 disjunctors, and top flange 2 is parallel with lower flange 3, near close two end bearings 1 of hoisting crane, adopt flat web 4, adopt two webs 5 between top flange 2 and the lower flange 3, two web 5 symmetries are placed, and are cellular structure, and two webs 5 adopt the single face fillet weld to be connected with top flange 2 or lower flange 3, and are corrugated web.
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
