Abstract
The utility model discloses a high-strength ladder type bridge frame for laying cables, comprising ladder strings and ladder ledges. The utility model is characterized in that: the bridge frame is provided with the ladder strings which have 3-shaped cross sections with hooks outward; ladder ledges, which have cross sections shaped like a Chinese character 'ao' and is provided with uniformly distributed holes lengthwise, are arranged vertically and uniformly on the bottom ends of the tow parallel ladder strings with the backs upward and hooks downward; The bridge frame of the utility model is enforced in terms of strength and rigidity, so the carrying capacity of the bridge is improved enormously and effectively by more than 25 percent compared with the prior bridge frame. The utility model is simple in structure and light in weight, and overcomes the drawbacks of the prior making method bridge frame, such as increasing the thickness of the board materials of the bridge frame, the number of the ladder strings and consequently the weight of the bridge frames.
Description
Technical field
The utility model is a kind of electrical equipment facility of usefulness of cabling, especially a kind of high-strength ladder type crane span structure.
Background technique
Under factories and miness and relevant occasion, adopt crane span structure to come cabling mostly, the weight of cable is born by crane span structure, and when more or cable size was big when the quantity of cable, the load that crane span structure bore was just very big, and at this moment, conventional crane span structure tends to produce deformation.For overcoming the above problems, traditional way is the thickness that increases crane span structure sheet material, and in fact this increased the deadweight of crane span structure, and the trailing arm that supports crane span structure and I-steel or channel-section steel have been had higher requirement again.
Summary of the invention
Technical problem to be solved in the utility model: be that a kind of deadweight that do not increase will be provided, can strengthen the high-strength ladder type crane span structure of bearing capacity again effectively.
For solving the technological scheme that above technical problem adopts is such: the utility model comprises ladder side and terraced Guang, it is characterized in that: this crane span structure is provided with and is figure of three section and crotch ladder side inwardly, between the two parallel ladder side lower ends, be provided with vertically uniform, the back side down, crotch up, be the terraced Guang of " recessed " font section.
Owing to adopt above technological scheme, produced useful effect:
1, simple in structure, in light weight.
2, under the situation that does not increase sheet metal thickness, strengthened the strength and stiffness of crane span structure, greatly improved the load-carrying ability of crane span structure simultaneously, to compare with traditional crane span structure, the utility model can improve load-carrying ability more than 25%.

Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the utility model comprises ladder side (1) and terraced Guang (2), it is characterized in that this crane span structure is provided with is figure of three section and crotch ladder side (1) inwardly, between the two parallel ladder side lower ends, be provided with vertically uniform, the back side down, crotch up, be the terraced Guang (2) of " recessed " font section.At first, ladder side (1) bending is the figure of three, terraced Guang (2) bending is " recessed " font, then, terraced Guang vertical welding is connected between the two parallel ladder side lower end crotches by design pitch.During welding, note inwardly, and with the back side of terraced Guang down, crotch up the crotch of ladder side.
Claims (1)
1. high-strength ladder type crane span structure, it comprises ladder side (1) and terraced Guang (2), it is characterized in that: this crane span structure is provided with and is figure of three section, and crotch ladder side (1) inwardly, between the two parallel ladder side lower ends, be provided with vertically uniform, the back side down, crotch up, be the terraced Guang (2) of " recessed " font section.
