Description
Technical field
A kind of crane span structure is the utility model is related to, is belonged 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.
Utility model content
It is adjustable that the technical problem that the utility model solves is to provide a kind of lateral dimension, can be according to different in actual installation
The width requirement of cable carries out the crane span structure of width adjustment;Further, the utility model provides one kind and can accounted for by deformation reduction
With space, freight volume is big, and more easy to maintain in transport after deformation, is not susceptible to due to caused deformation, the damaged bridge of colliding with
Frame.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of crane span structure, including:Two side plates being oppositely arranged, the bottom of the side plate is provided with inside lower flange, described
The top of side plate is provided with inside upper overturning, and the lower surface of the upper overturning is provided with the stepped projection of N levels, described stepped
Raised is first order step at the side plate, is N level steps at the stepped raised remote side plate, described in two
It is connected between lower flange 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 utility model, the setting of expansion link, make lateral dimension of the present utility model adjustable, can root
Width adjustment is carried out according to the width requirement of different cables in actual installation, versatile, flexibility is strong;Stepped raised sets
Put, effectively avoid cable from being slipped from wire casing, and prevent plowing from cable;Lived between the both ends of expansion link and lower flange by screw
The setting of dynamic connection, by adjusting the longitudinal separation between biside plate, expansion link can be in oblique, make twice flange and/or two
The side of upper overturning 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,
The freight volume of crane span structure can be effectively increased in fixed transport space, and after deformation, the side of twice flange and/or two upper overturnings
After face is in contact, load-bearing space diminishes, and the inside of crane span structure is fully protected, therefore more easy to maintain in transportation, is not easy to send out
It is raw due to caused deformation of colliding with, it is damaged the problems such as.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model 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 preferred embodiment of the present utility model, it should be pointed out that:For the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
