Abstract

The invention provides a novel crane girder structure, which relates to the technical field of crane girders. The crane girder structure comprises a girder, a telescopic shaft, an end girder, a positioning screw, a crane guide rail, a girder box body, grooves, connection web plates and I-steel, wherein, the girder is fixed on the telescopic shaft through the positioning screw, the telescopic shaft is sleeved on the end girder, the crane guide rail is arranged below the end girder, the U-type girder box body is arranged on the end surface of the girder, two sides of the girder box body are provided with the grooves, a left connection web plate, a right connection web plate and the girder box body form an integral frame structure, which enables raw materials to be saved, the strength of the girder to be enhanced and bearing capability of the girder to be improved, and the two connection web plates are welded and fixed on the I-steel. The invention has the following advantages: the structure is simple; relative height between the girder and the end girder to be adjustable, thereby changing working height of a crane and enlarging the application scope of the crane; the structures of the U-type girder box body and the grooves enable raw materials to be saved and the strength of the girder to be enhanced.

Description

A kind of novel crane girder structure

Technical field

The present invention relates to a kind of novel crane girder structure, belong to the girder technical field of hoisting crane.

Background technology

Hoisting crane is widely used in industrial and mining enterprises, is the requisite lifting appliance of production site.Owing to often be under the extra-heavy state, the intensity of crane girder enough height could guarantee the safety of equipment and operating personnel in the operation process.Traditional crane girder and end carriage connect as one usually, and girder and end carriage relative fixed, and the spacing of cart guide rail and vehicle guide can not be adjusted, thereby cause the operation height of hoisting crane can't change limited use.

Summary of the invention

Defective in view of prior art exists the purpose of this invention is to provide a kind of novel crane girder structure, uses the operation height that this girder also can be adjusted hoisting crane.

For realizing above-mentioned purpose, the present invention solves through following technical scheme: a kind of novel crane girder structure comprises girder, telescopic shaft, end carriage, fixing screw, cart guide rail, beam box body, groove, connection web, I-beam section; Girder is fixed on the telescopic shaft through fixing screw, and telescopic shaft is socketed on the end carriage, is the cart guide rail below the end carriage; The end face of said girder is a U type beam box body, has groove on the biside plate of beam box body, about two connect web and the beam box body is the general frame structure; Saved raw material like this; Strengthened the intensity of girder, the load-carrying capacity of girder is improved, two connect the web welding and are fixed on the I-beam section.

Said telescopic shaft moving up and down on end carriage drives moving up and down of girder, changes operation height.

Of the present invention simple in structure, can adjust the relative height between girder and end carriage, thereby change the operation height of hoisting crane, enlarged the field of application of hoisting crane, the structure of U type beam box body and groove had both been saved raw material, had improved the intensity of girder again.

Description of drawings

Fig. 1 is a kind of main beam structure sketch of novel hoisting crane;

Fig. 2 is an A-A section expanded view among Fig. 1.

Among the figure: 1, girder, 2, telescopic shaft, 3, end carriage, 4, fixing screw, 5, the cart guide rail, 6, the beam box body, 7, groove, 8, connect web, 9, I-beam section.

The specific embodiment

A kind of novel crane girder structure shown in Figure 1 comprises girder 1, telescopic shaft 2, end carriage 3; Fixing screw 4, cart guide rail 5, beam box body 6; Groove 7 connects web 8, I-beam section 9; Girder 1 is fixed on the telescopic shaft 2 through fixing screw 4, and telescopic shaft 2 is socketed on the end carriage 3, is cart guide rail 5 below the end carriage 1.

The A-A section expanded view of a kind of novel crane girder structure shown in Figure 2; The end face of girder 1 is a U type beam box body 6; Have groove 7 on the biside plate of beam box body 6, about two to connect webs 8 be the general frame structure with beam box body 6, two connect webs 8 and weld and be fixed on the I-beam section 9.

Said telescopic shaft 2 moving up and down on end carriage 3 drives moving up and down of girder 1, changes operation height.
