Abstract
The utility model relates to a trapezoid-shaped corrugated web box type main beam for a crane and belongs to the field of hoisting machinery. The trapezoid-shaped corrugated web box type main beam is composed of an upper flange plate, a lower flange plate, trapezoid-shaped corrugated webs and lateral plates. The trapezoid-shaped corrugated web box type main beam for the crane is characterized in that the upper flange plate and the lower flange plate are arranged parallelly, the two identical trapezoid-shaped corrugated webs are connected between the upper flange plate and the lower flange plate and the lateral plates in opposite and vertical mode, and a T-shaped steel reinforcing piece is connected between the trapezoid-shaped corrugated webs and the lower flange plate. The trapezoid-shaped corrugated webs replace flat webs in the prior art, the trapezoid-shaped corrugated 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 trapezoid-shaped corrugated web box type main beam has good economy and practicality.
Description
Technical field
The utility model is used for the ladder shaped corrugation web box type girder of hoisting crane, belongs to the elevator machinery 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 ladder shaped corrugation 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 utility model is achieved through the following technical solutions: this ladder shaped corrugation web box type girder, by upper and lower flange plate, ladder shaped corrugation web and side plate form, it is characterized in that upper and lower flange plate be arranged in parallel, two blocks of identical ladder shaped corrugation webs are vertically connected between top flange plate and bottom wing listrium, the side plate in opposite directions.
Be connected with the T-steel reinforcement between above-mentioned trapezoidal corrugated web and the bottom wing listrium.
The creative ladder shaped corrugation 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.
Description of drawings
Fig. 1 is the structural representation of the utility model casing girder
Fig. 2 is that the B-B of above-mentioned Fig. 1 is to schematic cross-section
Fig. 3 is that the A-A of above-mentioned Fig. 1 is to schematic cross-section
The specific embodiment
How now further specify by reference to the accompanying drawings the utility model implements:
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 ladder shaped corrugation webs 2 arrange along the flange plate length direction, be vertically welded in opposite directions top flange plate 1 and bottom wing listrium 3, between the side plate 4, be connected with T-steel reinforcement 5 between trapezoidal web 2 and the bottom wing listrium 3, the vertical plane of T-steel and 2 welding of trapezoidal web, the face of steel under water of T-steel and 3 welding of bottom wing listrium, with its local resistance to shear of further increase, the middle part of ladder shaped corrugation web 2 is provided with hole for hoist 6, electric block dolly 7 is installed on the bottom wing listrium 3, such as Fig. 1, shown in Figure 2; The design's ladder shaped corrugation web 2 is continuous ladder shaped corrugation at length direction, referring to Fig. 3.
Claims (2)
