Description
Technical field
The present invention relates to the auxiliary used when a kind of substation operation and service personnel's tour, inspection, operation, repair apparatus
A kind of tool, and in particular to insulation stool of substation's fixed deformable stair of safe self-locking.
Background technology
Substation operation and service personnel understand periodical inspection, inspection, operation, maintenance power supply unit, are often met in work
See provisional operation of ascending a height, for example makes an inspection tour and check ammeter, checks that anomalous line, interim operation replace electric appliance, maintenance power supply is set
It is standby.Staff is awkward in standing, and be easy to cause electric shock accidents, needs to be aided with stool or ladder class work
Tool could work.If in no ladder, it is superimposed stool with chair, since center of gravity improves, stool is easy to rock, dangerous
It is easy to happen, it is therefore necessary to there is special messenger to help.But if the people that climbs to a higher point falls down, it can also weigh wounded and help people.Therefore, stool everywhere
As it can be seen that the stair not insulated still, carry out it cannot be guaranteed that construction is normal, it is necessary to assign the special function of stool, exploitation one
The insulation stool of the kind fixed deformable stair of safe self-locking.
This technology seeks to the insulation stool processed using the insulating materials of electrical power demand.Both it can insulate, it can be with
Stair are deformed into, simplicity is used in power construction, it is ensured that safety.
Invention content
It is fixed with safe self-locking that in view of the above problems existing in the prior art, the purpose of the present invention is to provide a kind of substations
Deformable stair, the technical problem to be solved by the present invention is to how stair be enable to be deformed into stool.
Object of the invention can be realized by the following technical scheme：A kind of substation fixed deformable building of safe self-locking
Ladder, which is characterized in that this deformable stair includes half terraced body one and half terraced body two, and the half terraced body one includes two inclination foot of ladders
One and two vertical foot of ladder one, two inclination foot of ladders one and two tops for tilting foot of ladders two are fixed by a crossbeam one
It is connected, the bottom of two inclination foot of ladders one and two vertical foot of ladders one is fixedly linked by a rectangular bottom plate, and four
A foot of ladder is separately fixed at four edges and corners of bottom plate, the middle part of the middle part for tilting foot of ladder one and vertical foot of ladder one by one with
The parallel transverse slat one of bottom plate is fixedly linked；Described half terraced body two includes two and tilts foot of ladders two and two vertical foot of ladders two, two
The inclination foot of ladder two is connected with the top of two vertical foot of ladders two by a crossbeam two, it is described tilt foot of ladder two middle part and
The middle part of vertical foot of ladder two is fixedly linked by a transverse slat two parallel to the base plate, and the inclination foot of ladder one and inclination foot of ladder are second-class
Height, the vertical foot of ladder one and vertical foot of ladder two are contour, and the bottom plate is close to the side and two selectivity of crossbeam for tilting foot of ladder one
It is hinged, the stretching, extension knot that vertical foot of ladder one can be made to extend toward the lower section of vertical foot of ladder one is provided in two vertical foot of ladders one
Structure.
As ladder：After bottom plate is hinged close to the side for tilting foot of ladder one with crossbeam two, setting in two vertical foot of ladders one
There is the stretched out structure that vertical foot of ladder one can be made to extend toward the lower section of vertical foot of ladder one so that the lower section of vertical foot of ladder one extends to
Contour in vertical foot of ladder two, three pedals of bottom plate, transverse slat one, transverse slat two as this stair can during construction of transformer substation
It is very convenient and practical to be used as stair.
As stool：Two tilt foot of ladder one and two vertical foot of ladders two against inclination foot of ladder one and inclination foot of ladder are second-class
Height, vertical foot of ladder one and vertical foot of ladder two are contour, that is to say, that half terraced body one can be deformed into after merging with half terraced body two
One rectangular stool.
In the above-mentioned substation deformable stair fixed with safe self-locking, the stretched out structure is respectively set including two
In two vertical foot of ladders one and the longitudinal chute of lower ending opening, supporting rod is slidably connected in the longitudinal chute, it is described to stretch
Exhibition structure further includes two horizontal concrete chutes being arranged in bottom plate, and one end of two horizontal concrete chutes is described vertical with two respectively
It is communicated to sliding slot, is inserted with a positioning rod in two longitudinal chutes respectively, the upper end of the supporting rod and longitudinal chute
It is connected by drawstring between top surface, several locating slots is additionally provided on the supporting rod, one end of the locating rod can be plugged in
In the locating slot, the other end of the locating rod has a baffle, and a compression spring is arranged in the locating rod, the compression spring
Both ends are born against between the medial surface of the baffle and the lateral surface of bottom plate, and the lower end for tilting foot of ladder sets an evacuation
Mouthful, there are two step surfaces for the escape port tool, and the upper surface of the crossbeam two and a side can be born against described
On two step surfaces and keep the transverse slat one parallel with the transverse slat two.
When as stair, against ground, upper end passes through drawstring and longitudinal chute for the supporting rod lower end skidded off in longitudinal chute
Top be connected, locating rod one end in horizontal concrete chute is inserted into locating slot, and the baffle of the other end and crossbeam two are against locating rod
The status slot of selection different location can adjust the length that supporting rod stretches out in vertical foot of ladder direction, so as to adjust entire stair
Smoothness, this regulatory function improve the use of this stair but also this stair can steadily stand on uneven terrain
Range, the effect of compression spring enabled in the insertion locating slot that locating rod can be tightly, ensures stair in use
Stationarity and safety.
In the above-mentioned substation deformable stair fixed with safe self-locking, two upper ends for tilting foot of ladder two are all provided with
