Abstract

The utility model discloses a steel pipe support for a contact network and relates to the technical field of the contact network. The inner wall of a steel pipe body is fixedly provided with at least one arc liner plate for improving the bearing capacity of the steel pipe body. The liner plate extends to the end part of the steel pipe body along the axis of the steel pipe body. The liner plate is closely attached to the inner wall of the steel pipe body. Therefore, by the design, the thickness of the steel pipe body can be less than the thickness of the steel pipe body in the prior art, steels are saved, the different positions of the steel pipe body can have different bearing capacities by the supporting effect of the liner plate, the positions with high stresses have large bearing capacities by the liner plate, the positions with small stresses have small bearing capacities, the steel pipe body is stressed more reasonably, the using effect is not influenced, and under the condition of the same stress of the contact network, compared with the prior art, fewer steels used by the liner plate and the steel pipe body are used.

Description

The contact net tubular steel post

Technical field

The utility model relates to a kind of contact net technical field, relates in particular to a kind of contact net tubular steel post.

Background technology

The tubular steel post of present contact net normally by everywhere all the steel pipe of uniform thickness make, because the design feature of contact net decision, usually be subjected to the power of both direction on the tubular steel post, one is along circuit, one is horizontal path, the size of the power that is subjected on this both direction is different, when adopting the steel pipe of uniform thickness, the thickness of steel pipe must design according to the thickness of the described needs of power of its maximum of bearing, steel pipe bearing capacity everywhere is identical, can cause the thickness of steel pipe in stressed less place blocked up like this, cause waste.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of contact net tubular steel post is provided, and it is reasonable in design, can reduce the thickness of tubular steel post, saves steel, and does not reduce its result of use.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of contact net tubular steel post, comprise the steel pipe body, described steel pipe inner body wall is installed with at least one block of arc liner plate that is used to improve described steel pipe body bearing capacity, described liner plate extends to the end of described steel pipe body along the axis of described steel pipe body, and described liner plate is posted by the inwall of described steel pipe body.

As a kind of preferred version, described liner plate has two and be relatively arranged on the described steel pipe inner body wall.

As a kind of preferred version, described steel pipe body comprises two curved steel tube halfbodies that are fixed together.

After having adopted technique scheme, because described steel pipe inner body wall is installed with at least one block of arc liner plate that is used to improve described steel pipe body bearing capacity, because what the steel pipe body thickness can design is lower than the required thickness of its required maximum load capacity that bears greater than minimum bearing capacity desired thickness, so compared with prior art save steel, improve the bearing capacity of steel pipe body corresponding site by liner plate, make the stressed position that surpasses steel pipe body bearing capacity can sustain suffered maximum load capacity by the support of liner plate, the stressed bearing capacity at other position of steel pipe body less than the steel pipe body, therefore compared with prior art do not influence result of use, because described arc liner plate is posted by the inwall of described steel pipe body, therefore the circumferential total length of the described steel pipe inner body wall of described liner plate is less than the girth of described steel pipe body, can make the amount of the amount of liner plate and the two used steel of steel pipe body by reasonable computation less than steel used in the prior art, thereby saving steel, even according to actual conditions, thickness by appropriate design steel pipe body and liner plate, can be with same steel material, the bigger bearing capacity than tubular steel post of the prior art of maximum load capacity that the utility model can be carried is bigger, and the power that other position of steel pipe body is subjected to is no more than its bearing capacity, obtains better result of use.

Because setting up of contact net all is normalized, form is more unified, usually tubular steel post is stressed has only both direction, one is along line direction, therefore one is the horizontal path direction, and both direction is vertical, and described liner plate is set to two and be relatively arranged on the described steel pipe inner body wall, can conveniently design a large amount of production of being convenient to standardize like this.

Because described steel pipe body comprises two curved steel tube halfbodies that are fixed together, the manufacturing that can make things convenient for the steel pipe body is set so again.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is along the sectional view of A-A direction among Fig. 1;

Among the figure: 1, the steel pipe body; 11, the steel pipe halfbody; 2, liner plate; 3, base plate; 4, gusset.

The specific embodiment

Shown in Fig. 1 and Fig. 2 are common, a kind of contact net tubular steel post, comprise steel pipe body 1, described steel pipe body 1 inwall is installed with at least one block of arc liner plate 2 that is used to improve described steel pipe body 1 bearing capacity, described liner plate 2 extends to the end of described steel pipe body 1 along the axis of described steel pipe body 1, described liner plate 2 is posted by the inwall of described steel pipe body 1, by shown in Figure 2, described liner plate 2 has two and be relatively arranged on described steel pipe body 1 inwall, described steel pipe body 1 comprises two curved steel tube halfbodies 11 that are fixed together, described two steel pipe halfbodies 11 are fixed by welding in together, for easily manufactured two steel pipe halfbodies, 11 shapes identical, its cross section is semi arch.

When making, at first to calculate according to the load that tubular steel post will bear, through calculating steel pipe body 1 needed thickness, and liner plate 2 needed thickness, length and width, by calculating steel pipe body 1 and liner plate 2 used steel are lacked compared to existing technology as far as possible, according to calculating good data to the blanking of straight slab plate, the straight slab plate of following honest material is bent into steel pipe halfbody 11 and the liner plate 2 that needs, two steel pipe halfbodies 11 match and can constitute a steel pipe body 1, its one side fits tightly with the intrados of steel pipe halfbody 11 behind liner plate 2 bending formings, being welded on the steel pipe halfbody 11 liner plate 2 then, each steel pipe halfbody 11 is corresponding to be welded with a liner plate 2, and when guaranteeing that 11 pairs of two steel pipe halfbodies are welded together, liner plate 2 position symmetries, processing is fairly simple like this, and it is more durable, after steel pipe body 1 is made, itself and base plate 3 are welded together, loading characteristic according to contact net, usually when base plate 3 is installed, make all being positioned on the contact net horizontal path direction of two liner plates 2, be welded with gusset 4 around steel pipe body 1 outer circumferential side, gusset 4 is with 1 firm being fixed on the base plate 3 of steel pipe body.

The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
