Description
Technical field
The utility model is related to climbing tool, more particularly to steps on bar cat ladder.
Background technology
In power construction, maintenance process, power worker generally requires climbing electric pole and carries out operation, and electric pole is general
It is molded using cast in concrete, it is in integrally taper type and smooth in appearance, many power workers need to use cat ladder to climb.But
Existing cat ladder has two parallel columns, and the cross bar at several 30-40 centimetres of intervals is set between two columns, horizontal
The two ends of bar are separately fixed on two columns, and whole cat ladder is flatness structure.This cat ladder is leaned to when on utility poles, its
The strong point only has at the laminating points of two one cross bars in bottom and the superiors of column and electric pole, due to the surface ratio of electric pole
More smooth, fitting (put laminating) between the upper end of cat ladder and electric pole is very unstable, and then easily causes cat ladder double swerve,
Power worker is easy to topple over because of ground out-of-flatness or the bad balance of grasp after climbing up alone, or even triggers personal injury
Accident；Need to expend more human cost if a power worker is increased again if cat ladder is helped in lower section, and reduce construction
Efficiency, it is therefore necessary to be improved to existing cat ladder.
The content of the invention
The utility model is for the poor shortcoming of stationarity in the prior art, there is provided step on bar cat ladder.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：
Bar cat ladder, including ladder bars body are stepped on, ladder bars body includes at least two rod members, and rod member is hollow pipe and covers successively
Connect, the top of rod member is equipped with hole, and the bottom of rod member is equipped with locating slot, spring is mounted in locating slot, and spring is all connected with
There is the projection coordinated with hole；The side of rod member is equipped with storage tank, storage tank and is hinged with pedal；The top of rod member is respectively mounted
There is a retaining ring, retaining ring includes the first semi-ring and the second semi-ring, one end of one end of the first semi-ring and the second semi-ring is hinged on
On rod member, the opening of the first semi-ring and the second semi-ring is oppositely arranged, and the other end of the first semi-ring is provided with extension spring, tension bullet
Drag hook is installed, the other end of the second semi-ring is provided with the latch closure coordinated with drag hook on spring.Realize stepping on bar by the cooperation of rod member
Stretching for cat ladder, reduces storage and takes up an area, convenient to transport and storage；By the design of retaining ring, make to step on bar cat ladder and electric pole
Realize being connected for multi-point, it is ensured that the utility model has stronger stability during use, is not susceptible to climb
The rollover of ladder, protects the personal safety of staff.
Preferably, the first semi-ring and the second semi-ring are rigid semi-ring.
Preferably, being equipped with antiskid groove on pedal.The design of antiskid groove increased the coefficient of friction of pedal, effectively
Protect the safety of staff.
Preferably, being provided with the location-plate of control pedal rotational angle in storage tank.The design of location-plate prevents pedal
Transition is rotated, and is caused it to accommodate staff and is trampled.
The utility model as a result of above technical scheme, with significant technique effect：By the cooperation reality of rod member
The flexible of bar cat ladder is now stepped on, storage is reduced and is taken up an area, it is convenient to transport and deposit；By the design of retaining ring, make to step on bar cat ladder with
Electric pole realizes being connected for multi-point, it is ensured that the utility model has stronger stability during use, is difficult
There is the rollover of cat ladder, protect the personal safety of staff.

Specific embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Embodiment 1
Bar cat ladder is stepped on, as illustrated, including ladder bars body 1, ladder bars body 1 includes three rod members 2, and rod member 2 is hollow
Pipe and it is socketed successively, lifting and fixing device is provided between neighbouring two rod members 2, lifting and fixing device is, lower section one
The top of rod member 2 is equipped with hole 21, and the bottom of rod member 2 is equipped with locating slot 22, locating slot 22 and is mounted on spring 3, spring 3
The projection 4 coordinated with hole 21 is respectively connected with, projection 4 is mobile between hole 21 and locating slot 22 to form lifting fixed position, by bar
Part 2 is elongated upwards, when the locating slot 22 on interior rod member 2 and the level of hole 21 on outer rod member 2 to it is corresponding when locating slot 22 in
Projection 4 is outwards ejected and is stuck in hole 21 by the effect of spring 3, so as to the elongation for realizing rod member 2 is fixed, prevents rod member 2 from retracting,
If desired telescopic ladder bar body 1, need to only press inward against the projection 4 in hole 21 and simultaneously in interior rod member 2, force makes downwards
It is retracted；The side of rod member 2 is equipped with storage tank 23, storage tank 23 and is hinged with pedal 5, when ladder bars body 1 extends
Afterwards, the pedal 5 in storage tank 23 is rotated, horizontal level is at, facilitates trampling for staff；Pacify on the top of rod member 2
Equipped with retaining ring 6, retaining ring 6 includes the first semi-ring 61 and the second semi-ring 62, one end of the first semi-ring 61 and the second semi-ring 62
One end is hinged on rod member 2, and the opening of the first semi-ring 61 and the second semi-ring 62 is oppositely arranged, the other end peace of the first semi-ring 61
Equipped with extension spring 7, drag hook 8 is installed on extension spring 7, the other end of the second semi-ring 62 is provided with the ring coordinated with drag hook 8
Button 9, the surface of pinching of the first semi-ring 61 and the second semi-ring 62 is fitted on utility poles, pulls drag hook 8, drag hook 8 is buckled into ring
In button 9, so as to ladder bars body 1 be fixed on utility poles, due to being mounted on retaining ring 6 on each rod member 2, therefore make ladder bars
