Description

Insulation outlet flat ladder with scalable guardrail
Technical field
The present invention relates to a kind of outlet flat ladder.
Background technology
In recent years, as power grid construction continues to develop, the problem of being frequently run onto inclination of transmission line tower, dealing with improperly can Serious consequence can be caused to the safe operation of transmission line of electricity.Powered correction insulator is needed for tilting not serious shaft tower String, for the requirement to power supply reliability, typically all uses equipotential live line work.During Equipotential live working, using insulation Flat ladder is ridden on the support of shaft tower, and operating personnel now wears screening clothing and enters operation field, operating personnel station along insulated ladder The operation on insulated ladder.Existing insulated ladder does not have guardrail mostly because flat ladder is built in the air, if there is strong wind or Other situations of person, flat ladder are easy to rock, and influence the operating efficiency and operation effectiveness of operating personnel, while there is also safety Hidden danger.For there is probably high or other problems at heart operating personnels, stand does not have the sense of security in the flat ladder of no guardrail, influences The operation of operating personnel.
The content of the invention
In order to overcome disadvantages mentioned above, the present invention provides a kind of insulation outlet flat ladder of the scalable guardrail of band, including flat ladder master Body, two guardrails and some expansion brackets;The flat ladder main body includes two mobile jibs, some cross bars and some safety ropes; The cross bar is arranged between two mobile jibs, vertical with the mobile jib;One end of each safety rope is fixed on institute One end of flat ladder main body is stated, the other end is equipped with catching device;Two guardrails are fixed on described by some expansion brackets The surface of the mobile jib of flat ladder main body, it is parallel with two mobile jibs of the flat ladder main body;Each described expansion bracket is The expansion bracket of triangle.
Further, two locking systems are housed on each guardrail;Each described locking system includes support Bar and hinge;The strut is fixed on the guardrail by the hinge;The length of the strut is stretched equal to the expansion bracket Height after length.
Further, the top of the strut is provided with neck, the shape of the neck and the flat ladder main body upper rhabd Shape it is identical.
Further, the guardrail and the strut are provided with magnet, the magnet be located at respectively the guardrail and On the face of the strut contact.
The insulation outlet flat ladder of the scalable guardrail of band provided by the invention, provided with safety rope, one end of safety rope is fixed on In flat ladder, the other end is provided with catching device, can strengthen security, while provide the sense of security to equipotential live line work personnel;Provided with can Telescopic guardrail, security performance is improved, while be also convenient for storage when not in use;Provided with locking system, for nonfloating rail, prevent Guardrail glides, and improves the stability of guardrail.
Brief description of the drawings
Fig. 1 is the structural representation of flat ladder provided by the invention.
Fig. 2 is the top view of flat ladder provided by the invention.
Fig. 3 is the schematic diagram of the strut of flat ladder provided by the invention.
Embodiment
The present invention is described in further details below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, Figure 2 and Figure 3, the insulation outlet flat ladder of the scalable guardrail of band provided by the invention, including flat ladder master 10, two guardrails 20 of body and some expansion brackets 30;The flat ladder main body 10 includes two mobile jibs, some cross bars and some Safety rope 11;The cross bar is arranged between two mobile jibs, vertical with the mobile jib;The one of each safety rope 11 End is fixed on one end of the flat ladder main body 10, and the other end is equipped with catching device 12;Two guardrails 20 pass through described in some Expansion bracket 30 is fixed on the surface of the mobile jib of the flat ladder main body 10, flat with two mobile jibs 20 of the flat ladder main body 10 OK;Each expansion bracket 30 is the expansion bracket of triangle.
Specifically, two locking systems are housed on each guardrail 20;Each described locking system includes strut 21 and hinge 22;The strut 21 is fixed on the guardrail 20 by the hinge 22;The length of the strut 21 is equal to institute State the height after expansion bracket 30 extends.
Specifically, the top of the strut 21 is provided with neck, the shape of the neck and the upper rhabd of flat ladder main body 10 Shape it is identical.
Specifically, the guardrail 20 and the strut 21 are provided with magnet 23, the magnet 23 is being located at the shield respectively On the face that column 20 and the strut 21 contact.
When in use, the flat ladder main body 10 is hung over into operating location, then operation people personnel station is in the flat ladder main body On 10, the safety rope 11 with the catching device 12 is then fastened.By the guardrail 20 by the elongation of the expansion bracket 30 and Rise;And prop up the strut 21, the neck of the bottom of strut 21 is stuck on the mobile jib in the flat ladder main body 10, will The guardrail 20 is fixed.When not in use, the strut 21 is packed up, will by the guardrail 20 and the upper magnet of the strut 21 The strut 21 is fixed on the lower section of the guardrail 20, is easy to store.
Preferred embodiments of the present invention are these are only, therefore the scope that the present invention is implemented can not be limited according to this, i.e., according to the present invention The equivalence changes and decoration that description is made, it should all belong in the range of present invention covering.
