Abstract
A novel girder for an overhead traveling crane with an electric hoist relates to devices used on an overhead traveling crane with an electric hoist, and mainly comprises an upper cover plate, a web plate and a lower cover plate, wherein the web plate is arranged between the upper cover plate and the lower cover plate and connects the upper cover plate and the lower cover plate into a whole to form a box-type structure; a heavy plate serving as a guide rail is arranged at the joint of the web plate and the lower cover plate and welded on the lower cover plate; and angle iron is arranged in the middle of the web plate. The utility model has the benefits that as the Q345 heavy plate is arranged at the joint of the lower cover plate and the web plate to serve as the guide rail, the abrasion resistance is increased, the service life of the girder is prolonged, and the cross sectional moments of inertia, Ix and Iy, of the girder are improved to the utmost extent. Therefore, the average dead weight of the girder adopting the structure provided by the utility model is more than 15 percent smaller than that of a girder wrapped by an I-beam, and the load ratio of a crane is greatly reduced.
Description
Technical field
The utility model relates on the overhead crane with electric hoists and installing, and specifically is a kind of electric cucurbit bridging crane main beam.
Background technology
Overhead crane with electric hoists adopts integral solder with girder and end carriage in the indoor and outdoor hoisting operation that just is widely used in China's industry, enterprise in the early days of foundation on hoisting crane, transport very inconvenient.The seventies Renewal Design becomes job contract word die (referring to Fig. 1 a), to be 10t * 19.5m to the maximum.For meeting consumers' demand, if during greater than 10t * 19.5m, crane girder changes π type job contract word die (referring to Fig. 1 b) into.To entering 21st century, indivedual areas are expendable weight, adopt half root I-shaped die (referring to Fig. 1 c), though structure design has been saved the part material, resistance to overturning is bad, progressively eliminates now.Also having a kind of employing box-structure (referring to Fig. 1 d, 1e) mainly is to be used for external supporting design, because girder deadweight is bigger, and cost height and not seen widespread use.
The utility model content
The utility model has proposed a kind of electric cucurbit bridging crane main beam for the technical solution problem, has both prolonged the service life of girder, has improved the moment of inertia of girder again to greatest extent, reduces the deadweight of crane girder.
The utility model is achieved through the following technical solutions:
A kind of electric cucurbit bridging crane main beam, mainly comprise upper cover plate, web and lower cover, described web is arranged between upper cover plate and the lower cover, upper cover plate and lower cover fused be case structure, it is characterized in that: the junction of described web and lower cover is provided with the slab as guide rail, and described slab is to be welded on the lower cover, in the centre of described web angle steel is set also, be used for the horizontal drag of strengthening web, avoid the web deformation in compression.
The described thickness that is welded on the thickness of slab on the lower cover greater than vertical web on slab.
The quantity that angle steel is set on the described web is at least a pair of.
Described upper cover plate, web and lower cover adopt the Q235B steel to make, and the described slab that is provided for guide rail adopts the Q345 steel to make, and is used to strengthen the rigidity of guide rail, and and hoisting crane electric block wheel between fastness to rubbing.
The beneficial effects of the utility model are in the junction of lower cover and web the Q345 slab to be set to do guide rail, have not only increased fastness to rubbing, have improved the life-span of girder, and improve girder section moment of inertia I to greatest extent
x, I
yTherefore on average having reduced more than 15% from anharmonic ratio job contract word die girder of structure greatly reduces the California bearing ratio of hoisting crane.Good manufacturability helps realizing mechanization, automated production simultaneously.Also can satisfy user's low clearance selection according to mill construction.

The specific embodiment
In order further to understand goal of the invention, characteristics and the content of this utility model, describe in detail again below in conjunction with accompanying drawing:
As Fig. 2, Fig. 3 and shown in Figure 4, a kind of electric cucurbit bridging crane main beam, mainly comprise upper cover plate 1, web 2 and lower cover 3, web 2 is arranged between upper cover plate 1 and the lower cover 3, upper cover plate 1 and lower cover 3 fused be case structure, upper cover plate 1, web 2 and lower cover 3 all adopt the Q235B steel to make, be used as the slab 4 of guide rail by welding setting in the junction of web 2 and lower cover 3, the slab 4 of guide rail adopts the Q345 steel to make, be used to strengthen the rigidity of guide rail, and and hoisting crane electric block wheel between fastness to rubbing, slab 4 is welded on the lower cover 3, and is welded on the thickness of the thickness of slab 4 on the lower cover 3 greater than vertical web 2 on slab 4, in the centre of web 2 a pair of angle steel 5 is set also simultaneously, the specification of angle steel 5 selects for use the Q235 steel to make, specification is greater than 50 * 50 * 5mm, when girder height 〉=1200mm, adopts the angle steel 5 less than 50 * 75 * 6mm, in order to reinforce web 3, avoid web 3 deformation in compressions.
As shown in Figure 3 and Figure 4, a kind of electric cucurbit bridging crane main beam, mainly comprise upper cover plate 1, web 2 and lower cover 3, web 2 is arranged between upper cover plate 1 and the lower cover 3, upper cover plate 1 and lower cover 3 fused be case structure, upper cover plate 1, web 2 and lower cover 3 all adopt the Q235B steel to make, be used as the slab 4 of guide rail by welding setting in the junction of web 2 and lower cover 3, the slab 4 of guide rail adopts the Q345 steel to make, be used to strengthen the rigidity of guide rail, and and hoisting crane electric block wheel between fastness to rubbing, slab 4 is welded on the lower cover 3, and is welded on the thickness of the width of slab 4 on the lower cover 3 greater than vertical web 2 on slab 4.Because the length of web is too high, also add in the centre of web 2 this moment and put two pairs of angle steel 5, the specification of angle steel 5 selects for use the Q235 steel to make, usual angle steel 5 specifications of selecting for use of using are less than 50 * 50 * 5mm, when girder height 〉=1200mm, employing in order to reinforce web 3, is avoided web 3 deformation in compressions less than the angle steel 5 of 50 * 75 * 6mm.
