Abstract
The invention relates to a stiffened girder of an explosion-proof crane. The stiffened girder of the explosion-proof crane comprises a girder body. The girder body comprises two I-shaped beams arranged symmetrically. Upper transverse plates of the two beams are connected by welding and lower transverse plates of the two beams are connected by welding. The inside of the transverse plates is covered and welded with inner stiffening plates and the outside surfaces of the transverse plates are welded and fixed with outer stiffening plates. Two ends of each beam are connected with stiffening strips in a staggered mode and the two stiffened strips are arranged in a cross mode. According to the dual-I-shaped-girder structure provided by the invention, and by means of reinforcing the connection by the inner stiffened plates, the outer stiffened plates and the crossed stiffened strips, the stiffened girder has the characteristics of being simple in structure, good in carrying capacity and like.
Description
Technical field:
The present invention relates to explosion-proof crane, particularly to the girder of explosion-proof crane.
Background technology:
In prior art, the girder of explosion-proof crane is I-shaped structure, and its bearing capacity is less, is not suitable for large-scale, heavy equipment conveying.
Summary of the invention:
The disadvantages mentioned above that the applicant exists for prior art, carries out studying and designing, it is provided that the reinforcement type girder of a kind of explosion-proof crane, the feature that it has simple in construction, drafting efficiency is high, dustproof and waterproof is effective.
In order to solve the problems referred to above, the present invention adopts following scheme:
A kind of reinforcement type girder of explosion-proof crane, including girder body, described girder body includes the two I shape crossbeams being arranged symmetrically with, and the upper lower cross plate of two crossbeams is welded to connect, the inner side of transverse slat covers and is welded with interior reinforcing plate, and the lateral surface of transverse slat is welded with external reinforcement plate；
The two ends of two crossbeams have been cross-linked reinforcing strip respectively, in arranged crosswise between two reinforcing strip.
The method have technical effect that:
The present invention, by duplex font main beam structure, adds strong ties by the reinforcing strip of interior external reinforcement plate and intersection, the feature that it has simple in construction, bearing capacity is big.
Accompanying drawing illustrates:
Fig. 1 is the main sectional view of the present invention.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, the reinforcement type girder of the explosion-proof crane of the present embodiment, including girder body, girder body includes the two I shape crossbeams 1 being arranged symmetrically with, the upper lower cross plate 11 of two crossbeams 1 is welded to connect, the inner side of transverse slat 11 covers and is welded with interior reinforcing plate 2, and the lateral surface of transverse slat 11 is welded with external reinforcement plate 3；
The two ends of two crossbeams 1 have been cross-linked reinforcing strip 4 respectively, in arranged crosswise between two reinforcing strip 4.
The present invention, by duplex font main beam structure, adds strong ties by the reinforcing strip of interior external reinforcement plate and intersection, the feature that it has simple in construction, bearing capacity is big.
