Abstract
The utility model provides a tread of a dedicated cable bridge for nuclear power, which comprises a tread body. The tread body is an integral plate of which the longitudinal cross-section is shaped like the Greek letter 'Omega', so that the tread frame and the tread are in surface contact instead of the point contact in the prior art, resulting in the increase of contact area of the tread frame and the tread, enhancing the load-carrying capacity of the cable bridge, improving the overall shock resistance of the cable bridge, and effectively avoiding the problems of false welding and undercut of the welding process. Besides, the tread has the function of protecting the insulation coating of the cable, and greatly prolongs the service life and improves the safety property of the cable. Furthermore, as the longitudinal cross-section of the tread is shaped like the Greek letter 'Omega', the space of the cable is increased to form a special open-type tread frame structure, thereby promoting the heat dissipation of the cable, improving the management of the cable, providing convenience for maintenance and upgrading of the cable distribution, and greatly improving the safety property of the cable bridge.
Description
Technical field
The utility model relates to a kind of terraced Guang of crane span structure, belongs to the technical field of cable testing bridge parts.
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.Crane span structure comprises terraced limit, terraced Guang, and described terraced limit and described terraced Guang are fixed into one.Traditional terraced Guang is generally plate element, and some radiation holes evenly distribute on the terraced Guang.Because the crane span structure span is bigger, in order to guarantee the intensity of crane span structure, terraced Guang just must adopt thicker material to make, and can meet the demands the difficulty of bringing so just for transportation and construction just the thickness of common terraced Guang will reach 3mm; In addition, in the using process, because the weight of crane span structure is bigger, occur sinking easily, therefore, the maintenance of crane span structure has increased difficulty.
For intensity, bearing capacity and the bending resistance that improves crane span structure, recently, a kind of crane span structure has appearred, the terraced Guang of this crane span structure is provided with stiffening rib, like this, can make crane span structure keep reducing the weight of crane span structure on the original intensity based, thereby greatly reduce the transportation and the difficulty of construction of crane span structure, and efficiently solve the problem that crane span structure sinks.
The content of model utility
Technical problem to be solved in the utility model provides a kind of intensity height, and bearing capacity is strong and simple in structure, the terraced Guang of the bridge frame dedicated for nuclear power of convenient transportation.
In order to solve the problems of the technologies described above, the terraced Guang of a kind of bridge frame dedicated for nuclear power of the utility model comprises terraced Guang body, and wherein, described terraced Guang body is that the longitudinal section is the whole plate of Ω type.
The terraced Guang of above-mentioned a kind of and bridge frame dedicated for nuclear power wherein, evenly is provided with some mounting holes on the bottom surface of described terraced Guang.
The utility model can be realized following beneficial effect:
1, because the longitudinal section of described terraced Guang is the whole plate of Ω type, traditional terraced limit is connected with terraced Guang, become the face contact by a contact, increased the area of contact of terraced limit and terraced Guang, thereby increased the load-carrying ability of crane span structure, improve the whole anti-seismic performance of crane span structure, and solved defectives such as the rosin joint that produces in the welding procedure, undercut effectively; In addition, owing to adopt Ω type ladder Guang to reduce friction, the isolation layer of cable is played a protective role, improved the working life and the Safety performance of cable greatly cable; And because the longitudinal section of described terraced Guang is the Ω type, make the cable space become big, formed distinctive open terraced limit structure, thereby helped the heat radiation of cable, and can better the management and control cable, be convenient to the maintenance and the upgrading of circuit, improved the Safety performance of crane span structure greatly; In addition, the utility model only is that the terraced Guang shape of crane span structure has been made improvement, and is therefore, easy to process and simple in structure.
2, owing to evenly be provided with some mounting holes on the bottom surface of described terraced Guang, during installation, cable is installed by this mounting hole, thereby has made things convenient for the cable laying operation of cable and fixing.
Description of drawings
Fig. 1 is a structural representation of the present utility model
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, the terraced Guang of a kind of bridge frame dedicated for nuclear power of the utility model comprises terraced Guang body 1, wherein, described terraced Guang body 1 is the whole plate of Ω type for the longitudinal section, because the longitudinal section of terraced Guang body 1 is the whole plate of Ω type, has increased the terraced limit of crane span structure and the area of contact of terraced Guang, thereby has increased the load-carrying ability of crane span structure, improve the whole anti-seismic performance of crane span structure, and solved defectives such as the rosin joint that produces in the welding procedure, undercut effectively; In addition, owing to adopt Ω type ladder Guang to reduce friction, the isolation layer of cable is played a protective role, improved the working life and the Safety performance of cable greatly cable; And because the longitudinal section of terraced Guang is the Ω type, make the cable space become big, formed distinctive open terraced limit structure, thereby helped the heat radiation of cable, and can better the management and control cable, be convenient to the maintenance and the upgrading of circuit.For convenience cable is fixing, some mounting holes 3 that also can evenly distribute in the bottom surface of terraced Guang 1, thus be convenient to the installation, fixing of cable.
In sum, the utility model compared with prior art has the intensity height, and bearing capacity is strong, the good and advantage of simple structure of anti-seismic performance.
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.
Claims (2)
1. the terraced Guang of a bridge frame dedicated for nuclear power is characterized in that, described terraced Guang is that the longitudinal section is the whole plate of Ω type.
2. a kind of terraced Guang of bridge frame dedicated for nuclear power according to claim 1 is characterized in that, evenly is provided with some mounting holes on the bottom surface of described terraced Guang.
