Background technology
Existing electricity meter-reading and maintenance ladder, the double ladder obtained mostly using that can purchase on the market, specific
In, there is problems with：Need the area of meter reading larger, stand and want on ladder when stretching laterally, without handrail, people
Body loses support, and control can only be gone to balance by Equilibrium ability, and safety coefficient is low；In addition, when human body stretches laterally, ladder
Sub- center of gravity is changed, and ladder is easily toppled over, therefore, and a kind of ladder for providing arm supports and preventing ladder from toppling over needs to be opened
Hair.
In order to solve the problem of above is present, people are seeking a kind of preferable technical solution always.
The content of the invention
The purpose of this utility model is in view of the shortcomings of the prior art, so as to provide a kind of design science, increase rotatably
The handrail of angle make it that hand steered space is big, increases safe tensioning apparatus so that being difficult to topple over, lifted a kind of safety electricity of security
Power meter reading and maintenance ladder.
To achieve these goals, the technical scheme that the utility model is used is：A kind of security power meter reading and maintenance
With ladder, it includes two main ladders of composition herringbone ladder, two main terraced upper articulations, and it also includes high-order hand steered device and limit
Position device, the high-order hand steered device includes four curved bars, and each curved bar includes the connecting portion of straight line and the handhold portion of bending,
The connecting portion of the curved bar is arranged on main terraced upper outside by hinge post, and the stopping means includes rotating around the hinge post
And the ratchet fixed with the connecting portion of curved bar, the ratchet that is hinged on main terraced upper outside and coordinates with ratchet and control the ratchet
Depart from the operation knob of ratchet, the main terraced lower outside sets the neck for being caught in the curved bar.
Described on base, it also includes safe tensioning apparatus, and the safe tensioning apparatus includes upper articulation on main ladder
Two supporting legs and the drawstring being connected on each supporting leg, two supporting legs are separately positioned on the main ladder above main terraced front and rear sides, supporting leg
Place opens lower opening, and the upper hole that drawstring is penetrated in lower opening and opened up from the main terraced a certain position in top is stretched out, the extension connection of drawstring
Roller is installed in one cranse, the lower end of supporting leg, and the supporting leg turns to roller lower surface when being alignd with main ladder and is higher than main terraced lower surface
The limitation supporting leg is set to be rotated up to the limiting plate of angle on 2-4cm, the main ladder.
The utility model has substantive distinguishing features and progress compared with the prior art, and specifically, the utility model is in main ladder
Upper to install high-order armrest system, handrail can be carried out the positioning of angle by stopping means, when standing high-order, helped with rotational angle
Hand is raised, during standing low level, handrail reduction, and comprehensive protection, the position-limit mechanism angle with ratchet device are carried out to human body
Scope of compromise is wider.
Further, safe tensioning apparatus is increased, cranse hoop is on the person, when human body extends laterally, drawstring is tensed,
Supporting leg is pulled to lift, triangle is formed on bottom, even if ladder center of gravity itself is offset, the supporting part of triangle also can be by ladder
Son is propped up, it is to avoid toppled over.

Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
As shown in figure 1, a kind of security power meter reading and maintenance ladder, it includes two main ladders of composition herringbone ladder
1, two main terraced 1 upper articulations, it also includes high-order hand steered device and stopping means, and the high-order hand steered device includes four curved bars
2, each curved bar 2 includes the connecting portion 3 of straight line and the handhold portion 4 of bending, and the connecting portion 3 of the curved bar 2 is installed by hinge post 5
In main terraced 1 upper outside, the hunting range of curved bar 2 is larger, disclosure satisfy that the demand of different height.
As shown in Fig. 2 the stopping means includes the spine for rotating and being fixed with the connecting portion 3 of curved bar 2 around the hinge post 5
Wheel 6, the ratchet 7 for being hinged on main terraced 1 upper outside and coordinating with ratchet 6 and the control ratchet 7 depart from the operation knob of ratchet 6
8, main terraced 1 lower outside sets the neck for being caught in the curved bar 2, during using handrail, will be lifted on curved bar 2, due to ratchet
The presence of detent mechanism, curved bar 2 can realize one-directional rotation, and the positioning of many gears, adjustable angle solution is in extensive range.
When in use, main terraced 1 is supportted, curved bar 2 is taken out out of neck, certain angle is put on hinge post 5, reach work
Make the position of height, then climb up main terraced 1 and operated, curved bar 2 both can also support human body with hand steered, be easy to adjust
Balance, when needing to arrive higher position, is rotated further curved bar 2, reaches higher position；When need to pack up curved bar 2 or
When person turns down curved bar 2, ratchet 7 is departed from ratchet 6 by rotation process knob 8, and ratchet 6 is turned back into relevant position, operation letter
It is single.
In order to lift security, it also includes safe tensioning apparatus, and the safe tensioning apparatus includes upper articulation in master
Two supporting legs 11 and the drawstring 10 being connected on each supporting leg 11 on ladder 1, two supporting legs 11 are separately positioned on front and rear the two of main terraced 1
Side, the top of supporting leg 11 main terraced 1 at open lower opening, drawstring 10 penetrates the upper hole opened up in lower opening and from the main terraced a certain position in 1 top
Stretch out, the extension of drawstring 10 connects a cranse 9, and roller is installed in the lower end of supporting leg 11, and the supporting leg 11 is turned to and main terraced 1
Roller lower surface, which is higher than on main terraced lower surface 2-4cm, described main terraced 1, during alignment sets the limitation supporting leg 11 to be rotated up to angle
Limiting plate 12.
In use, cranse 9 is bundled in the waist of people, during human body flare, drawstring 10 is pulled, drawstring 10 pulls supporting leg 11 to rotate again
Upper lift, forms the support of triangle, not in contact with the ground in normal state after supporting leg 11 is propped up, only in ladder centre-of gravity shift
When causing to topple over, supporting leg contact ground is supported, it is to avoid topple over.
Finally it should be noted that:Above example is only to illustrate the technical solution of the utility model rather than it is limited
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
