Description
Technical field
The present invention relates to the flat ladder of a kind of outlet.
Background technology
In recent years, along with power grid construction development, the problem being frequently run onto inclination of transmission line tower, deal with improperly and the safe operation of transmission line of electricity may be caused serious consequence.Need charged rectification insulator chain for tilting the most serious shaft tower, for the requirement to power supply reliability, the most all use isoelectric level live line work.During Equipotential live working, using insulated ladder to ride on the support of shaft tower, operating personnel now wears screening clothing and enters operation field along insulated ladder, and operating personnel stands in operation on insulated ladder.Existing insulated ladder does not has guardrail mostly, because flat ladder is built aloft, if there is strong wind or other situations, flat ladder is easy to occur rocking, and affects working performance and the operation effectiveness of operating personnel, there is also potential safety hazard simultaneously.For there being the highest or operating personnel of other problems at heart, stand in and there is no on the flat ladder of guardrail there is no the security, affect the operation of operating personnel.
Summary of the invention
In order to overcome disadvantages mentioned above, the present invention provides a kind of insulation outlet with guardrail flat ladder, including flat ladder main body, two guardrails and several support bars；Described flat ladder main body includes two side rods, some cross bars and two safety ropes；Described two side rods are parallel to each other, and described cross bar is fixed between two described side rods；Each described cross bar is all vertical with two described side rods；One end of each described safety rope connects a described cross bar, and the other end is provided with catching device；Two described guardrails are connected by described strut and two described side rods, fix the surface of two described side rods, parallel with two described side rods respectively；Each described strut is all to be connected by roller with described side rod and described guardrail.
Further, the two ends of each described strut are equipped with roller；Described roller is fixed on each described strut；Each described roller is provided with a groove；Each described guardrail is provided with several fixing devices with on side rod each described in identical position；Each described fixing device includes two pieces of baffle plates, spring, bullet block and bolt；The centre of each piece of described baffle plate is provided with through hole, and described bullet block is arranged on the centre of two pieces of described baffle plates by described spring, is fixed on described guardrail or described side rod；Described roller is arranged between two pieces of described baffle plates, and described roller and two pieces of described baffle plates are fixed by described bolt.
Further, described guardrail and described side rod are all hollow cylinders；Described guardrail and described side rod are provided with hole, described spring and described bullet block equipped with the position of described fixing device and are arranged in described hole.
The flat ladder of the insulation outlet with guardrail that the present invention provides, is provided with safety rope, and one end of safety rope is fixed on flat ladder, and the other end is provided with catching device, can strengthen safety, provides the security to equipotential live line work personnel simultaneously；It is provided with guardrail, improves security performance；Each strut is connected by roller with described guardrail and described side rod, conveniently packs up or rise described guardrail；It is provided with fixing device, for nonfloating rail, prevents guardrail from gliding, improve the stability of guardrail.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
As shown in Figure 1, Figure 2 and Figure 3, the flat ladder of the insulation outlet with guardrail that the present invention provides, including flat ladder main body, two guardrails 20 and several support bars 30；Described flat ladder main body includes two side rods 11, some cross bars 12 and two safety ropes 13；Described two side rods 11 are parallel to each other, and described cross bar 12 is fixed between two described side rods 11；Each described cross bar 12 is all vertical with two described side rods 11；One end of each described safety rope 13 connects a described cross bar 12, and the other end is provided with catching device 14；Two described guardrails 20 are connected with two described side rods 11 by described strut 30, fix the surface of two described side rods 11, parallel with two described side rods 11 respectively；Each described strut 30 is all to be connected by roller 31 with described side rod 11 and described guardrail 20.
Concrete, the two ends of each described strut 30 are equipped with roller 31；Described roller 31 is fixed on each described strut 30；Each described roller 31 is provided with a groove 32；Each described guardrail 20 be provided with several fixing devices 40 on side rod each described 11 in identical position；Each described fixing device 40 includes two pieces of baffle plates 41, spring 42, bullet block 43 and bolt 44；The centre of each piece of described baffle plate 41 is provided with through hole, and described bullet block 43 is arranged on the centre of two pieces of described baffle plates 41, is fixed on described guardrail 20 or described side rod 11 by described spring 42；Described roller 31 is arranged between two pieces of described baffle plates 41, and described roller 31 is fixed by described bolt 44 with two pieces of described baffle plates 41.
Concrete, described guardrail 20 and described side rod 11 are all hollow cylinders；Described guardrail 20 and described side rod 11 are provided with hole 21, described spring 42 and described bullet block 43 equipped with the position of described fixing device 40 and are arranged in described hole 21.
