Description
Technical field
The present invention relates to a kind of fireproof bridge frame, 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 one
As without fire-proof function, and cable fire spreading speed on fire is fast, deals with improperly and easily causes very big economic loss, if without and
When processing fire development seriously can then cause personal casualty loss, therefore there is potential safety hazard in existing crane span structure.Further, 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 be to provide it is a kind of with fire-proof function, once alert occurs to put out a fire immediately,
The condition of a fire and Risk health behavior in minimum crane span structure；Further, a kind of lateral dimension of present invention offer is adjustable, can be according to actual peace
The width requirement of different cables carries out the fireproof bridge frame of width adjustment in dress；Further, the present invention provides one kind and can passed through
Deformation reduces space-consuming, and freight volume is big, and more easy to maintain in transport after deformation, is not susceptible to due to caused change of colliding with
Shape, damaged fireproof bridge frame.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of fireproof bridge frame, 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 some cross-arms；Fine sand is filled with the stepped projection, the bottom surface of the N level steps is activity
Door, one side of the dodge gate is hinged with the N level steps, the another side of the dodge gate and the N levels step it
Between be connected by electromagnetic switch, the electromagnetic switch is connected with controller, the controller and the fire being arranged on the side plate
Alert alarm is connected.
The cross-arm is 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.
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.
The controller includes MCU or CPU.
The fire alarm includes temperature sensing warner and/or smoke-sensitive alarm device.
A kind of fireproof bridge frame provided by the invention, the fine sand of stepped raised interior filling, dodge gate, electromagnetic switch, control
The combination settings of device and fire alarm, caught fire once cable occurs, after fire alarm detects, be sent to controller, controlled
Device processed control electromagnetic switch opens dodge gate, and fine sand is quickly dropped down onto on cable by gravity, realizes quick extinguishing, so the condition of a fire with
Risk health behavior is in minimum；The setting of expansion link, make the lateral dimension of the present invention adjustable, can be according to different cables in actual installation
Width requirement carries out width adjustment, and versatile, flexibility is strong；Stepped raised setting, cable is effectively avoided to be slided from wire casing
It is de-, and prevent plowing from cable；The setting being flexibly connected between the both ends of expansion link and lower flange by screw, pass through adjustment two
Longitudinal separation between side plate, expansion link can be in oblique, the side of twice flange and/or two upper overturnings is in contact, i.e.,
This crane span structure is set to deform, the crane span structure width after deformation diminishes, and takes up space and diminishes, can be effective in fixed transport space
Increase the freight volume of crane span structure, and after deforming, after the sides of twice flange and/or two upper overturnings is in contact, load-bearing space diminishes,
The inside of crane span structure is fully protected, therefore more easy to maintain in transportation, is not susceptible to due to caused deformation, the breakage of colliding with
The problems such as.
