Abstract
The utility model discloses an abnormal-shaped joist steel which is arranged under a girder of a motor-driven single-girder crane and formed by the integration of an upper leg, a lower leg and a middle, wherein the joint parts of the legs and the middle are arc surfaces. The abnormal-shaped joist steel is characterized in that the inner side face of the upper leg and the lower leg are arc surfaces which are opposite and extend towards the outer side of the middle, and the edges of the outer ends of the legs are arc surfaces. The widths of the legs are 128mm, the thickness of the middle is 12mm, and the height of the middle is 300mm. The abnormal-shaped joist steel has the advantages of abrasion resistance, good using effects, and the like.
Description
Technical field
The utility model relates to the mechanical part technical field, more particularly relates to a kind of special-shaped I-beam section that is used on the hoisting crane.
Background technology
I-beam section also claims girder steel, is that the cross section is the rectangular steel of double-tee, is widely used in various building structure, bridge, vehicle, support, machinery etc.; At present, in the important part of the force of mono beam overhead crane girder is I-beam section, and the resistance to abrasion of its material structure, stress-bearing capability directly have influence on service life of single-beam crane girder, there is this problem mostly in the common I-beam section of on the market this type of, and the improved place of needs is arranged.
The utility model content
The purpose of this utility model is exactly in order to solve the deficiency of prior art, and a kind of resistance to abrasion that provides is good, the special-shaped I-beam section that stress-bearing capability is strong.
The utility model is to adopt following technical solution to realize above-mentioned purpose:
A kind of special-shaped I-beam section, be arranged under the mono beam overhead crane girder, connect and compose by leg up and down and middle waist integral type, in leg waist junction is arc surface, it is characterized in that: described special-shaped I-beam section shank medial surface up and down is the relative cambered surface of extending towards the waist outside, and the edge, outer end is an arc surface.
As further specifying of such scheme, the leg of described special-shaped I-beam section is wide to be 128mm, and waist is thick to be 12mm, and the waist height is 300mm.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The inner side angle of the utility model abnormity I-beam section adopts cambered surface, and side outwardly is the inclination cambered surface, and the leg plate thickness strengthens, and is stressed, load range is bigger; As the important part of the force of mono beam overhead crane girder, to compare with common I-beam section, main advantage is wear-resisting, the service life of directly improving single-beam crane is more than at least 50%.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a construction profile scheme drawing of the present utility model;
Fig. 3 is a running condition scheme drawing of the present utility model.
Description of reference numerals: 1 special-shaped I-beam section, 2 girders, 3 medial surfaces.
The specific embodiment
As shown in Figure 1, special-shaped I-beam section 1 of the present utility model, be arranged on the mono beam overhead crane girder 2 times, connect and compose by leg up and down and middle waist integral type, its inboard leg waist joint portion up and down is an arc surface, and the described medial surface 3 of shank up and down is symmetrical cambered surface, and cambered surface is extended towards the waist outside, low relatively high extension of the cambered surface of last leg, the cambered surface of following leg height is relatively extended; And edge, leg outer end is an arc surface.Described special-shaped I-beam section is the 30# I-beam section, and leg is wide to be 128mm, and waist is thick to be 12mm, and the waist height is 300mm.
Only be one of the utility model preferred embodiment shown in the utility model the foregoing description and the accompanying drawing, can not limit to the utility model with this.Under the condition that does not break away from the utility model marrow, any change that those skilled in the art did all belongs to protection domain of the present utility model.
Claims (2)
1. special-shaped I-beam section, be arranged under the mono beam overhead crane girder, connect and compose by leg up and down and middle waist integral type, in leg waist junction is arc surface, it is characterized in that: described special-shaped I-beam section shank medial surface up and down is the relative cambered surface of extending towards the waist outside, and edge, leg outer end is an arc surface.
2. special-shaped I-beam section according to claim 1 is characterized in that: the leg of described special-shaped I-beam section is wide to be 128mm, and waist is thick to be 12mm, and the waist height is 300mm.
