Abstract

The invention relates to a main girder structure for an anti-explosion crane. The main girder structure comprises a main girder body. The main girder body comprises two I-shaped transverse girders arranged symmetrically. An upper transverse plate and a lower transverse plate of each transverse girder are in welded connection with each other. Inner reinforcing plates are welded to the inner sides of the transverse plates in a covering mode. Outer reinforcing plates are welded to the outer sides of the transverse plates in a fixed mode. According to the main girder structure for the anti-explosion crane, by arranging the main girder structure which is in a double-I shape and reinforced and connected through the inner reinforcing plates and the outer reinforcing plates, the main girder structure has the characteristics of being simple in structure and large in bearing capacity.

Description

The main beam structure of explosion-proof crane

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 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 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 method have technical effect that:

The present invention, by duplex font main beam structure, adds strong ties by interior external reinforcement plate, 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 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 present invention, by duplex font main beam structure, adds strong ties by interior external reinforcement plate, the feature that it has simple in construction, bearing capacity is big.

Claims (1)
