Description
Technical field:
The invention belongs to maintenance power equipment ascend operation facility technology field, relate in particular to the novel ladder of a kind of power equipment primary cut-out novel ladder.
Technical background:
In power equipment repairing high-voltage breaker operation process, the major accident of the casualties that happens occasionally is arranged during because porcelain knob ruptures.Therefore, State Grid Corporation of China sternly forbids when the electric power apparatus examination operation, the climbing porcelain insulator, and to produce [2004] No. 222 documentation requirements of peace: " conscientiously study and define P.P's measure; solve the maintainer in overhaul, the method for cleaning, disappearing and climbing porcelain vase and hanging safety belt when lacking ", and " State Grid Corporation of China's electric power safety working regulation " 13.6 regulation safety belts must not high hang and be of use, forbid be hang over move or unstable object on.During therefore domestic maintenance power equipment, can only be by crane or console mode inspection platform, the former exist space, required place big, use loaded down with trivial detailsly, time-consuming, the latter exists and moves difficulty, and is difficult near maintenance position, poor safety performance.
Summary of the invention:
The present invention is in order to solve when the repairing high-voltage breaker operation, and personnel climb porcelain insulator and safety belt is the extension problem, provides a kind of and can guarantee personal safety, reduces labour intensity, increases work efficiency, and improves the novel ladder of the repair quality of equipment.
The present invention solves its technical problem scheme: a kind of novel ladder that is used for the repairing high-voltage breaker operation, it is supported by Insulation ladder, reinforcement and base constitutes, it is characterized in that, Insulation ladder by ladder and can the two sides pedal of upset constitute, the lower end is provided with rotary reinforcement and supports, and base is made of fixing clamping plate and metal plate.On the ladder that insulating material is made, pedal is set, pedal is provided with diagonal brace and spacing stop, track by down in the ladder shelves both sides, can pack up or keep pedal to be in level, pedal can overturn to another side as required, personnel stand in operation on the pedal about ladder, needn't climb porcelain insulator; The ladder bottom links to each other with the straight pin that usefulness is supported in the reinforcement of ladder, strengthens supporting the bottom and links to each other with base with straight pin, and two ends all can be rotated; The ladder lower end is provided with and pulls many ribs pin that automatically resets, and many ribs pin inserts the pin-and-hole on the base, is used for reducing because of rocking that the accumulation of rotating shaft gap causes; Ladder, reinforcement are supported, base, constitute stable straight triangle; Keeping can also passing through shirtsleeve operation under the motionless situation of base, the upkeep operation of circuit breaker adjacent interruptions is carried out in the upright position of conversion ladder in the opposite direction; For preventing that personal height from falling, the ladder top installs buckle for safety belts additional.
Above-mentioned base is to be welded into an integral body by metal plate, many ribs pin-and-hole seat of stablizing ladder, the cylinder pin hole seat that connects the reinforcement support, train wheel bridge etc., is fixed on the circuit breaker framework by screw rod with lower plate, does not need to enlarge specially space for maintenance; Install an accessory case at the clear position of metal plate, be used for collecting annex.
One end of above-mentioned clamping plate is opened a slotted hole, and the other end bores row's circular hole, for selecting for use on the circuit breaker framework of different size; Make the teeth groove shape around the slotted hole, with the pad interlock that has teeth groove, and the anti-sliding stop of tie down screw.
The above-mentioned many ribs pin that automatically resets that pulls is made of back-moving spring, shell, pin, handle, and pin has the corner angle more than three.
For alleviating base weight, fabrication hole can be set on base plane.
The invention has the beneficial effects as follows provides a kind of novel ladder that is used for the repairing high-voltage breaker operation, at the alternate firm banking of circuit breaker, through the simple position conversion, can carry out the service work of two adjacent fractures, the personnel of having solved climb porcelain vase and be the hanging safety belt problem, the safety when ensureing maintainer's normal operation, and easy to use simple to operate, improve efficiency simultaneously, saved production cost.
