Description
Technical field
The utility model relates to overhaul of line breaker technical fields, more particularly, to a kind of overhaul of line breaker step ladder.
Background technique
Three pole 50Hz high-tension power transmission and transformation equipment of sulfur hexafluoride breaker system outdoor AC is used for division rated current, failure
Electric current or conversion line realize protection, control and operation to power transmission and transformation system.The breaker has structure simple, small in size
The features such as consumptive material is few, high reliablity, and installation is easy, low noise, is widely used in electric system.
The breaker is when carrying out periodic preventative test, the operations such as service personnel tears open, connects primary connection, by
In the wiring of breaker top, vertical range is high from the ground and superstructure is cylinder, and service personnel uses commonly at work
Ascending tool safety is poor, easily leads to the generation of safety accident.
Utility model content
In view of the shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a kind of overhaul of line breaker with stepping on
High ladder uses easy purpose to reach safe and efficient.
In order to solve the above-mentioned technical problem, the technology employed by the present utility model is
The top of the overhaul of line breaker step ladder, including step ladder main body, the step ladder main body is equipped with for ascending a height
Step, the lower part of the step ladder main body is equipped with the opening for being stuck on the girder of breaker, and opening is equipped with for locking
The tightly movable connecting rod on girder.
Further, the step ladder main body is frame structure.
The lower part of the step ladder main body is equipped with a pair of of the snap-gauge stretched out, forms the opening between a pair of of snap-gauge.
The step surface of the step is equipped with non-slip mat.
The step surface both sides of the edge of the step are equipped with protrusion positive stop strip.
Location hole is equipped on the pair of snap-gauge at relative position, movable connecting rod is the screw rod that may pass through location hole,
The end of screw rod is equipped with locking nut.
The bottom of the step ladder main body, which is located between a pair of of snap-gauge, is equipped with rubber pad.
The utility model compared with prior art, has the advantage that overhaul of line breaker step ladder structure design is closed
Reason, can be nested on the girder of breaker and use, compact-sized, and using simplicity, the safety of maintenance greatly improved；And it ties
Structure is simple, at low cost, easy to operate.
Detailed description of the invention
Content expressed by each width attached drawing of this specification and the label in figure are briefly described below:
Fig. 1 is the utility model step ladder use state diagram.
Fig. 2 is the utility model step ladder structural schematic diagram.
In figure:
1. step ladder main body, 2. breaker girders, 3. movable connecting rods I, 4. movable connecting rods II.
Specific embodiment
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
Thin explanation.
As depicted in figs. 1 and 2, the overhaul of line breaker step ladder, including step ladder main body 1, the top of step ladder main body 1
Equipped with the step for ascending a height, the lower part of step ladder main body is equipped with the opening for being stuck on breaker girder 2, and opening is equipped with
Movable connecting rod for being locked on girder.
Step ladder main body 1 is frame structure, can be by angle steel welding production, and at low cost, stable structure is reliable；And make platform
Rank, easy access personnel selection height.
The step surface of step is equipped with non-slip mat, and the step surface both sides of the edge of step are equipped with protrusion positive stop strip, improve maintenance
The safety of personnel's operation.
The lower part of step ladder main body is equipped with a pair of of the snap-gauge stretched out, forms the opening between a pair of of snap-gauge.A pair of of snap-gauge
Location hole is equipped at upper relative position, movable connecting rod is the screw rod that may pass through location hole, and the end of screw rod is equipped with locking screw
It is female.
Movable connecting rod is two be arranged side by side, respectively movable connecting rod I 3 and movable connecting rod II 4, and two activities are even
The setting of extension bar side by side parallel, it is reliable and stable after step ladder positioning, it is not easy to shake.
The bottom of step ladder main body, which is located between a pair of of snap-gauge, is equipped with rubber pad, also further is provided on the inside of snap-gauge
Rubber pad, it is reliable and stable after step ladder locking positioning, it is not easy to shake on breaker girder, improves the safety of maintenance.
It can be nested on the girder of breaker and use, structure is too big without what is done, and using simplicity, maintenance greatly improved
Safety；And structure is simple, at low cost.
It above are only and preferred embodiments of the present invention are illustrated, above-mentioned technical characteristic can form multiple hairs in any combination
Bright example scheme.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as the improvement for the various unsubstantialities that the conception and technical scheme for using the utility model carry out,
Or it is not improved the conception and technical scheme of the utility model are directly applied into other occasions, in the guarantor of the utility model
Within the scope of shield.
