Description
Technical field
The utility model is related to one kind and ascended a height equipment, more particularly, to transformer station and the operation of ascending a height of High-Voltage Electrical Appliances measuring station
Halfpace.
Background technology
Operation of ascending a height is the common homework type of transformer station and High-Voltage Electrical Appliances testing agency.High-tension apparatus, extra-high voltage equipment
With bulky feature, personnel need aloft to carry out operation.Carry out stepping on used in electric power overhaul or testing operation at present
High equipment has electric power ladder truck, vertical ladder, telescopic vertical ladder, step ladder etc..Electric power ladder truck involves great expense, it is necessary to which professional grasps
Make.And common vertical ladder, telescopic vertical ladder and contracted-pole ladder are required to place by mode, or winding fastening is placed, easily to examination
Test sample or power equipment causes to damage.Common step ladder is highly fixed, and height, job platform proportional with its volume
Height is higher, and required space is more, and move mode is more inconvenient.Accordingly, it would be desirable to design a kind of cheap, simple in construction, square
Just the equipment of ascending a height of property by force.
Utility model content
The utility model is for equipment travelling performance difference or the valency of being ascended a height used in existing transformer station and High-Voltage Electrical Appliances testing agency
A kind of step ladder that may span across obstacle movement of the expensive present situation of lattice there is provided cheap, simple in construction, convenience by force.
A kind of step ladder that may span across obstacle movement of the utility model, primary structure includes：It is ladder, workbench, flexible
Formula vertical ladder, universal wheel, lowering or hoisting gear.Characterized in that, workbench is fixed at the top of ladder；Telescopic vertical ladder is with certain angle
Degree is fixed on ladder, and pedal is installed on ladder, above and below staff, can adjust overall high by manually above pushing away telescopic vertical ladder
Degree；Be staggered installation of in the ladder bottom left and right sides six it is universal, can by lowering or hoisting gear carry out universal wheel lift and fall it is dynamic
Make.
Lowering or hoisting gear of the present utility model includes stepper motor, shaft coupling, screw mandrel, fixed base plate, and stepper motor passes through connection
Axle device is fastened on fixed base plate with screw mandrel, and screw mandrel lower end is directly fixedly connected with universal wheel.By setting stepper motor
Rotating, drives screw mandrel to make vertical direction up and down motion so that can be moved up and down with the universal wheel being connected, and realization is lifted and fallen
Under action.
The step ladder described in the utility model that may span across obstacle movement is compared with existing step ladder and ladder truck, knot
Structure is simple, travelling performance is good, with higher application and popularization value.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the front view of the present utility model that may span across obstacle moveable step ladder.
Fig. 2 is the schematic diagram of lowering or hoisting gear in Fig. 1.
In figure, 1 is ladder, and 2 be workbench, and 3 be telescopic vertical ladder, and 4 be lowering or hoisting gear, and 5 be universal wheel, and 6 be stepping
Motor, 7 be shaft coupling, and 8 be fixed base plate, and 9 be screw mandrel.
Embodiment
As shown in Figure 1, 2, the step ladder described in the utility model that may span across obstacle movement, primary structure includes：Ladder
1, workbench 2, telescopic vertical ladder 3, lowering or hoisting gear 4, universal wheel 5.Workbench 2 is fixed on the top of ladder 1, telescopic straight
Ladder 3 is fixed on the side of ladder 1 at a certain angle, and whole height, stepper motor 6 are adjusted by manually above pushing away telescopic vertical ladder 3
It is fastened on by shaft coupling 7 and screw mandrel 9 on fixed base plate 8, the lower end of screw mandrel 9 is directly fixedly connected with universal wheel 5, fixed seat
Plate 8 carries out bolt connection with ladder 1 and fixed.
The rotating of stepper motor 6 can be set in lowering or hoisting gear 4, drives screw mandrel 9 to move up and down, so that the universal wheel being attached thereto
5 can also move up and down, and realize the action lifted and fallen.
The moveable step ladder specific implementation method described in the utility model that may span across obstacle is as follows：
First, barrier is run into during staff's moveable step ladder, control stepper motor is rotated forward, and rotation drives screw mandrel
Motion upwards so that the universal wheel being attached thereto realizes after the action lifted, across obstacle that control stepper motor is inverted, rotation
Turn drive screw mandrel to move downward so that the universal wheel being attached thereto realizes the action fallen；
Second, six universal wheels for controlling the left and right sides to be interspersed successively are lifted and fallen action, so that
Step ladder is completely across obstacle；
3rd, by step ladder movement by test specimen, operating personnel can carry out operation on workbench, or pass through
Telescopic vertical ladder is above manually pushed away, step ladder is regulated to proper height, operating personnel carries out operation on ladder.
Claims (4)
