Abstract
The utility model relates to a sine-corrugation web box type main beam for a crane and belongs to the field of hoisting devices. The sine-corrugation web box type main beam is composed of an upper flange plate, a lower flange plate, sine-corrugation webs and lateral plates. The upper flange plate and the lower flange plate are arranged parallelly, the two identical sine-corrugation webs are connected between the upper flange plate and the lower flange plate and the lateral plates in opposite and vertical mode, and a reinforcing plate is connected with the bottom of the lower flange plate. The sine-corrugation webs replace flat webs in the prior art, the sine-corrugation web box type main beam is good in stability, shearing resistance and fatigue resistance. Use amount of steel can be greatly reduced under the condition of the same strength, self-weight is reduced, implementation and installing are convenient, and the sine-corrugation web box type main beam has good economy and practicality.
Description
Technical field
The utility model is used for the sine bellows web box type girder of hoisting crane, belongs to the weight-lifting equipment field.
Background technology
Hoisting crane is as the main mechanical of material lifting, transportation, loading and unloading or installation, in the national economic development of China, obtained extensive utilization, strengthened research and the improvement of hoisting crane are of great significance improving China's material lifting, transportation, loading and unloading or the horizontal tool of installation.The hoisting crane that present China is widely used in the industries such as machinery, metallurgy, transportation, electric power, coal, building mainly is crane in bridge type, and the crane span structure of crane in bridge type is main load-carrying element, and it mainly bears deadweight and hoisting heavy weight.Box type girder then is one of base model of crane in bridge type metal crane span structure.Present common employing be flat web box type girder, avoiding local buckling, but the unrelieved stress of welding has also caused a little less than the bending resistance of flat web girder, shearing resistance, the local compression ability simultaneously the flat web of prior art by the welding ribbed stiffener; And the existing flat web manufacturing cycle is long, and consumable material is many, and productive costs is high, can not adapt to growing demand.
The utility model content
The purpose of this utility model provides a kind of sine bellows web box type girder for hoisting crane, stability, shearing resistance, fatigue durability that can not only the lift crane box type girder, and save material, easily manufactured.
The purpose of this utility model is achieved through the following technical solutions:
The utility model sine bellows web box type girder, by upper and lower flange plate, sine bellows web and side plate form, and it is characterized in that upper and lower flange plate be arranged in parallel, and two blocks of identical sine bellows webs are vertically connected between top flange plate and bottom wing listrium, the side plate in opposite directions.
Described bottom wing listrium bottom surface is connected with brace panel.
The creative sine bellows web that adopts of the utility model has replaced the flat web of prior art, the design has good stability, shear resistance, fatigue resistance, and, under equality strength, can greatly reduce the steel use amount, alleviate deadweight, implement easy for installationly, good economy and practicality are arranged.

Fig. 3 is that the A-A of above-mentioned Fig. 1 is to cutaway view
The specific embodiment
Now 1-3 further specifies the utility model and how to implement by reference to the accompanying drawings.
Top flange plate 1 and the bottom wing listrium 3 of the design's hoisting crane box type girder be arranged in parallel, the two ends of top flange plate 1 and bottom wing listrium 3 are connected with respectively side plate 4, two blocks of identical sine waveform webs 2 arrange along the flange plate length direction, be vertically welded in opposite directions between top flange plate 1 and bottom wing listrium 3, the side plate 4, bottom wing listrium 3 two bottom sides are welded with reinforcement plate steel plate 5, to increase its local resistance to shear, the middle part of girder web plate 2 is provided with hole for hoist 6, electric block dolly 7 is installed on the bottom wing listrium 3, as shown in Figure 1, 2; The design's sine bellows web 2 is continuous sine waveform at length direction, referring to Fig. 3.
Claims (2)
