Abstract

The utility model relates to a main girder of a double girder crane and double girder crane using the same, the main girder of the double girder crane comprises a top cover plate, a bottom cover plate and two web plates arranged between the top cover plate and the bottom cover plate. at least one of the top cover plate, the bottom cover plate and two web plates is in an integrally-formed structure, According to the main girder of the double girder crane, the conventional assembly and welding top cover plate, bottom cover plate and two web plates are changed into the integrally-formed structure, thus the rigidity of the main girder of the double girder crane is greatly increased, the downwarping of the main girder of the double girder crane in the work is effectively reduced, moreover, the production cost of the main girder is reduced, the service life of the main girder is increased, and the service life of the double girder crane is also increased.

Description

Double girder crane girder and use the double girder crane of this girder
Technical field
The utility model relates to the large lifting equipment field, especially a kind of double girder crane girder and use the hoisting crane of this girder.
Background technology
At present, known two-beam type hoisting crane comprises two girders that be arranged in parallel, the cooresponding end of described two girders connects by end carriage respectively, described end carriage bottom is provided with hoist frame, be provided with guide rail and actuating unit between described end carriage and the described hoist frame, realize that with this described hoisting crane moves along the axis direction of described end carriage, described girder top is provided with vehicle guide, and be provided with the lifting dolly that can move by described guide rail along the axis direction of described girder, because described lifting dolly is arranged on the described girder, when dolly is sling weight, girder has carried very big gravity, especially when dolly carrying weight travels centre portion to described girder, the downwarp phenomenon usually can take place because load is overweight in described girder, after in case this phenomenon occurring, in order to guarantee safety in production, must shut down finishing, this has brought great inconvenience for normal production, simultaneously, because the rectification of described girder requires a great deal of time and money, this has also brought enormous economic loss to the user; Yet the girder of existing two-beam type hoisting crane mostly is to be welded by the multistage assembly unit, and the rigidity of the described crane girder that this further reduces makes its easier generation downwarp phenomenon; In addition, owing to adopt the multistage assembly unit to be welded, wasted a large amount of welding materials, and because welder's technical merit is uneven, the butt weld poor welding quality tends to produce local deformation, make precision and be difficult to control, make the intensity of described crane girder be difficult to be difficult to more guarantee.
The phenomenon of above-mentioned crane girder downwarp has also seriously influenced the normal operation of hoisting crane simultaneously, has improved the production and the maintenance cost of two-beam type hoisting crane.
Summary of the invention
The purpose of this utility model is to provide a kind of double girder crane girder, to solve existing crane girder because the downwarp phenomenon that multistage is spliced and causes; Simultaneously, the purpose of this utility model also is to provide a kind of hoisting crane that uses above-mentioned girder.
For achieving the above object, double girder crane girder of the present utility model adopts following technical scheme: the double girder crane girder, this double girder crane girder comprises top, bottom plate and is arranged at two webs between top, the base plate, and at least one is the global formation structure in four of described top, base plate and described two webs.
Described two webs are the global formation structure.
Described top, base plate are the global formation structure.
Described top, base plate and described two webs are the global formation structure.
Double girder crane of the present utility model adopts following technical scheme: a kind of double girder crane, this double girder crane comprises two girders that be arranged in parallel, described girder comprises top, base plate and is arranged at two webs between top, the base plate, and at least one is the global formation structure in four of described top, base plate and described two webs.
Described two webs are the global formation structure.
Described top, base plate are the global formation structure.
Described top, base plate and described two webs are the global formation structure.
Two-beam type crane girder of the present utility model changes top, base plate and the web of the two-beam type crane girder of traditional assembly unit welding into integrated formed structure, this has increased the rigidity of described double girder crane girder greatly, actv. has slowed down the downwarp phenomenon that described two-beam type crane girder occurs when work, simultaneously, also reduce the productive costs of described girder, increased the service life of described girder; Can only all change integrated formed structure to one in described top, base plate and the biside plate or any two or three into.
Two-beam type hoisting crane of the present utility model changes top, base plate and the web of the two-beam type crane girder of traditional assembly unit welding into integrated formed structure, this has increased the rigidity of described double girder crane girder greatly, actv. has slowed down the downwarp phenomenon that described two-beam type crane girder occurs when work, simultaneously, also reduce the productive costs of described girder, increased the service life of described hoisting crane; Can only all change integrated formed structure to one in described top, base plate and the biside plate or any two or three into.

The specific embodiment
As Fig. 1-shown in Figure 5, the two-beam type crane girder, comprise top board 1, base plate 2 and be arranged at described top, two webs 3 between the base plate, described top, base plate is captiveed joint with the form of welding with described two webs 3, described top, base plate and described web constitute a box body, described top, the width of base plate is greater than the distance between described two webs 3, described top, base plate has one section respectively at the outside of described two webs and goes out the edge, described top, base plate has one section and is used for and crane end carriage bonded assembly sponson 4, described top in the two ends of described double girder crane girder, base plate and described two webs 3 all are the global formation structure.
In the above-described embodiments, can also be only arbitrary, two or three employing global formation structures in four of described top, base plate and described two webs.
As shown in Figure 6, double girder crane comprises girder 5, and described girder 5 is identical with the structure of the double girder crane girder shown in Fig. 1-5.
