Description
Technical field
The present invention relates to a kind of crane span structure, belongs to for distribution technique field.
Background technology
Crane span structure is as the device for being used for fixed cable for field of power distribution, and its application is very extensive, current crane span structure knot
Structure is generally the trench structure being made up of bottom plate and two side plates, and the structure is integrated formed structure, the width on lateral dimension
It is fixed, the width requirement of different cables in actual installation can not be met.In addition, existing portal structure shape is generally fixed
It formula, can not deform, space-consuming can not be reduced by deforming in transit, so as to realize convenient and transport in a larger amount
It is defeated.
The content of the invention
Present invention solves the technical problem that it is adjustable to be to provide a kind of lateral dimension, can be according to different cables in actual installation
Width requirement carry out width adjustment crane span structure；Further, the present invention provides one kind can reduce space-consuming, fortune by deformation
Throughput rate is big, and more easy to maintain in transport after deformation, is not susceptible to due to caused deformation, the damaged crane span structure of colliding with.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of crane span structure, including：Two side plates being oppositely arranged, the bottom of the side plate are provided with inside lower flange, the side plate
Top be provided with inside upper overturning, the lower surface of the upper overturning is provided with the stepped projection of N levels, the stepped projection
Be first order step at the side plate, be N level steps at the stepped raised remote side plate, two it is described under turn over
It is connected between side by expansion link.
The expansion link includes two outer bars positioned at interior bar both ends described in middle interior bar and difference outsourcing, the outer bar
To be slidably connected between interior bar, the end of the outer bar is connected with lower flange.
Described be slidably connected connects including slide rail chute type.
N is >=3 natural number.
Reinforcement is provided with the side plate.
The reinforcement includes broken line type or linear pattern.
The both ends of the expansion link and the junction of the lower flange are provided with circular hole, after screw passes through two circular holes
Fixed by nut, the small 3 ~ 6mm of diameter of the diameter circular hole of the bar portion of the screw, the diameter on the head of the screw is big
In the diameter of the circular hole.
A kind of crane span structure provided by the invention, the setting of expansion link, make the lateral dimension of the present invention adjustable, can be according to actual peace
The width requirement of different cables carries out width adjustment in dress, and versatile, flexibility is strong；Stepped raised setting, effectively keeps away
Exempt from cable to slip from wire casing, and prevent plowing from cable；It is flexibly connected between the both ends of expansion link and lower flange by screw
Set, by adjusting the longitudinal separation between biside plate, expansion link can be in oblique, make twice flange and/or two upper overturnings
Side can be in contact, even if this crane span structure can deform, the crane span structure width after deformation diminishes, and takes up space and diminishes, fixed
The freight volume of crane span structure can be effectively increased in transport space, and after deformation, the side of twice flange and/or two upper overturnings is in contact
Afterwards, load-bearing space diminishes, and the inside of crane span structure is fully protected, therefore more easy to maintain in transportation, is not susceptible to due to knocking
Touch caused deformation, it is damaged the problems such as.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of crane span structure, including：Two side plates 1 being oppositely arranged, the bottom of the side plate 1 are provided with inside
Lower flange 2, the top of the side plate 1 are provided with inside upper overturning 3, and it is stepped that the lower surface of the upper overturning 3 is provided with N levels
Projection 4, described stepped raised 4 is first order step at the side plate 1, and described stepped raised 4 away from the side plate 1
Locate as N level steps, be connected between the two lower flange 2 by expansion link 5.
The expansion link 5 includes two outer bars 7 positioned at the both ends of interior bar 6 described in middle interior bar 6 and difference outsourcing, described
To be slidably connected between outer bar 7 and interior bar 6, the end of the outer bar 7 is connected with lower flange 2.
Described be slidably connected connects including slide rail chute type.
N is >=3 natural number.
Reinforcement is provided with the side plate 1.
The reinforcement includes broken line type or linear pattern.
The both ends of the expansion link 5 and the junction of the lower flange 2 are provided with circular hole 8, and screw 9 passes through two circles
Fixed behind hole 8 by nut, the small 3 ~ 6mm of diameter of the diameter circular hole 8 of the bar portion of the screw 9, the head of the screw 9
Diameter be more than the circular hole 8 diameter.
Described above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
