Abstract
The utility model provides a novel rigid plastic bridge frame. The bridge frame comprises a cover plate and a groove body; two side plates of the groove body is respectively connected with the cover plate through connecting devices; each connecting device comprises a flange fixedly arranged at the upper end of the corresponding side plate of the groove body, and a convex edge vertically and fixedly arranged on the bottom surface of the cover plate; a groove is formed on the flange; and the convex edge is clamped in the groove. Through the close fit of the convex edge and the groove on the edge, the cover plate is connected with the groove body to form a whole, thereby facilitating the mounting of the bridge frame; and when the bridge frame works in a severe environment, rainwater permeating into the bridge frame can only be gathered in the groove and has low probability of entering the bridge frame, thereby improving the water-proof performance of the bridge frame.
Description
Technical field
The utility model relates to a kind of crane span structure, and the crane span structure that particularly a kind of rigid plastics is made belongs to the technical field of equipment for power transmission and distribution.
Background technique
Cable testing bridge is extensive in sector applications such as oil, chemical industry, electric power, light industry, telecommunications, is mainly used in laying of empty power cable, actuating cable, illuminating line, telecommunication cable, has relatively high expectations for intensity, the bearing capacity of crane span structure.Traditional cable testing bridge is processed by steel material, therefore need not only consume a large amount of energy through multi-step process such as overpickling, phosphatization, spraying or hot galvanizings, and heavy contamination; In addition, also make processing more loaded down with trivial details.
A kind of plastic-steel crane span structure has appearred in processing recently for convenience, comprises cover plate, cell body, cover plate is arranged on the upper end of described cell body by connection set, wherein, connection set is generally padlock, the plastic-steel crane span structure of this structure, because cover plate is connected by padlock with cell body, fitting surface between cover plate and the cell body is the plane, and therefore, water-proof performance is relatively poor, and install loaded down with trivial detailsly, cost is higher.
The content of model utility
Technical problem to be solved in the utility model provides good, the with low cost and simple in structure novel rigid plastics crane span structure of a kind of water-proof performance.
In order to solve the problems of the technologies described above, a kind of novel rigid plastics crane span structure of the utility model, comprise cover plate, cell body, the biside plate of described cell body is connected by connection set respectively with described cover plate, wherein, described connection set comprises the flange that is fixedly installed on described cell body side plate upper end, and vertical fixing is arranged on the chimb on the described cover plate bottom surface, described flange is provided with groove, and described chimb is stuck in the described groove.
Above-mentioned a kind of rigid plastics crane span structure, wherein, described cell body is an overall structure, is made up of side plate and base plate, groove shaped is processed in described side plate and described base plate once-through.
The utility model can be realized following beneficial effect:
1, because described connection set comprises the flange that is fixedly installed on described cell body side plate upper end, vertical fixing is arranged on the chimb on the described cover plate bottom surface, during connection, drive fit by chimb and flange upper groove links into an integrated entity cover plate and cell body, thereby made things convenient for the installation of crane span structure, and when crane span structure when working under the rugged environment, rain penetration is gone into crane span structure and is accumulated in the groove only, and be not easy to enter in the crane span structure, thereby, improved the water-proof performance of crane span structure, and can play the better protect effect the cable in the crane span structure, thereby, the Security that has improved whole crane span structure greatly; In addition, the utility model has reduced the use of padlock, has reduced cost and simple in structure.
2, because described cell body is an overall structure, is processed into groove shaped by side plate and base plate once-through and forms, reduced the input of mould, reduced the cost of production of enterprise, improved the intensity of cell body; And the utility model is simple in structure.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure; in order to solve the problems of the technologies described above; a kind of novel rigid plastics crane span structure of the utility model; comprise cover plate 1; cell body 2; the biside plate 21 of described cell body 2 is connected by connection set respectively with described cover plate 1; described connection set comprises flange 22; chimb 12; flange 22 is fixedly installed on side plate 21 upper ends of described cell body; chimb 12 is fixedly installed on described cover plate 1 bottom surface; and be connected with the bottom surface of cover plate 1 is vertical, described flange 22 is provided with groove 221, and described chimb 12 is stuck in the groove 221 of described flange 22; by the drive fit of chimb 12 cover plate 1 and cell body 2 are linked into an integrated entity with flange upper groove 221; thereby made things convenient for the installation of crane span structure, and when crane span structure when working under the rugged environment, rain penetration is gone into crane span structure and is accumulated in the groove only; and be not easy to enter in the crane span structure; thereby, improved the water-proof performance of crane span structure, and can play the better protect effect the cable in the crane span structure; thereby, the Security that has improved whole crane span structure greatly.
Described cell body 2 can be overall structure, also can be the branch body structure, in the present embodiment, in order to improve the intensity of crane span structure, preferably cell body 2 is designed to overall structure, cell body 2 is made up of side plate 21 and base plate 20, groove shaped is processed in described side plate 21 and 20 once-throughs of described base plate, cover plate 1 and cell body 2 process by rigid plastics, because described cell body 2 is an overall structure, be processed into groove shaped by side plate 21 and base plate 20 once-throughs and form, reduced the input of mould, reduced the cost of production of enterprise; And cell body 2 of the present utility model forms for once-through, and is not only simple in structure, and easy to process.
In sum, the utility model compared with prior art has advantage simple in structure, with low cost, easy to process and that intensity is good.
Here description of the present utility model and application are illustrative; be not to want in the above-described embodiments with scope restriction of the present utility model; therefore, the utility model is not subjected to the restriction of present embodiment, and the technological scheme that any employing equivalence replacement obtains is all in the scope of the utility model protection.
