Description
Technical field
The utility model relates to flight-line maintenance utensil, particularly a kind of combined trolley step stool.
Background technology
It is higher owing to showing meter installation site that work of transformer substation personnel make a copy of table timing every day, and staff checks, operation needs ascend operation, takes the measure using ascending table at present; O&M record made a copy of by outdoor equipment in addition, hangs dismounting ground wire, takes to use ladder ascend operation.These two kinds of ascending tool function singlenesses, and carrying gets up to waste time and energy.When going to place of working, the tool equipment that staff needs other means of transport to come needed for loading operation, so both adds manpower and turn increases cost of transportation.
Utility model content
Ascending tool function singleness when the purpose of this utility model is to solve work of transformer substation personnel ascend operation, and carrying gets up to waste time and energy, and increases the shortcomings such as cost of transportation, and a kind of combined trolley step stool proposed.
To achieve these goals, the utility model have employed following technical scheme:
A kind of combined trolley step stool, it is characterized in that: comprise insulation combination casing, combination box connects at least one group of roller, described combination box comprises lower box, described lower box to be connected upper box by connector, described upper box can fold to the side of lower box, the lower chamber of one end open is provided with in described lower box, described upper box is provided with the upper cavity of one end open, upper cavity and described lower chamber are in the same side, in two cavitys, equal activity is connected one group of pedal, two groups of pedals are engaged in respectively in corresponding cavity and form trapezoidal-structure, after described upper box and lower box fold, lower chamber and upper cavity form closed cavity.
On the basis of technique scheme, following further technical scheme can be had:
Described lower box is by least one keeper and described upper box location fit.
The inwall of described lower chamber and upper cavity is respectively equipped with at least one group of block, each block is equipped with draw-in groove, described pedal is movable to be respectively engaged in corresponding draw-in groove.
Described roller is universal wheel, casing wheel skeleton steel prepared material, and plastic roller is smooth not fragile.
Described combination box adopts the wooden boards with comparatively strong insulation, and density is large, and intensity is high, and supporting power is large, and hinges steel material, abrasion hardness is large.
In draw-in groove, pedal can conveniently extract, and installs;
Burst preferred hinge connects detachable, assembling, and the location such as burst alignment pin, combination fasteners are fixing, turn back, rock after preventing people from stepping on.
The cavity capacity of combination box is large, is convenient to deposit operation instrument.
Diverse in function, singlely just can combine as required.
Advantage of the present utility model: this device is convenient to combination and is simple and easy to dress, roller design, and pulling is light, securely, time saving and energy saving, and diverse in function is easy to use, and then promotes maintenance craft, shortens the repair time, greatly improves overhaul efficiency, reduce entreprise cost.
