Abstract
The invention relates to a main beam structure of a heavy explosionproof crane. The main beam structure comprises a main beam body; the main beam body includes two I-shaped cross beams symmetrically arranged; upper and lower transverse plates of the two cross beams are connected through welding; the inner sides of the transverse plates are covered and welded with inner reinforcing plates; the outer side surfaces of the transverse plates are welded and fixed with outer reinforcing plates; the transverse plates between vertical plates of the two cross beams are fixedly connected with mounting blocks; tension springs are arranged between the mounting blocks of the upper and lower transverse plates; reinforcing bars are staggered, welded and fixedly connected between the mounting blocks, and are in a cross arrangement; and the crossed parts of the reinforcing bars are connected through welding. The double-I-shaped main beam structure has the characteristics of simple structure and high bearing capacity through reinforcing connection of the inner and outer reinforcing plates, the reinforcing bars and the tension springs due to the double I-shaped main-beam structure thereof.
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 main beam structure of a kind of heavy 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 main beam structure of heavy 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；
Being fixed with mounting blocks on transverse slat between the riser of two crossbeams, between the mounting blocks of upper lower cross plate, device has extension spring, and between mounting blocks, staggered welding is fixed with reinforcing strip, and in arranged crosswise between reinforcing strip, its cross part is welded to connect.
The method have technical effect that:
The present invention, by duplex font main beam structure, adds strong ties by interior external reinforcement plate, reinforcing strip and extension spring, 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 main beam structure of the heavy 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；
Being fixed with mounting blocks 4 on transverse slat 11 between the riser 12 of two crossbeams 1, between the mounting blocks 4 of upper lower cross plate 11, device has extension spring 5, and between mounting blocks 4, staggered welding is fixed with reinforcing strip 6, and in arranged crosswise between reinforcing strip 6, its cross part is welded to connect.
The present invention, by duplex font main beam structure, adds strong ties by interior external reinforcement plate, reinforcing strip and extension spring, the feature that it has simple in construction, bearing capacity is big.
