Description
Technical field
The invention belongs to insulating ladder technical fields, and in particular to a kind of portable ladder type insulated platform.
Background technique
Double ladder is also referred to as folding step, because of it in use, preceding for a kind of ascending tool that side space in the plane works
Ladder bars and ground afterwards constitute an isosceles triangle, it appears that are known as ' herringbone as ' people ' word, thus its image
Ladder '.
Practical double ladder has fixed double ladder and moving herringbone ladder.Fixed double ladder is that people temporarily build tool；It is living
Dynamic double ladder is that the top of two ladders is connected together with loose-leaf, can be flexible due to it altogether when mobile
Property, therefore be widely used in temporarily ascending a height in operation.The double ladder of early stage is usually what timber made, with the hair of metal industry
Exhibition utilizes aluminum alloy materials more now；Aluminium alloy herringbone ladder has light, beautiful, durable feature, and cost is not high, therefore by
It is widely used.
Insulating ladder is chiefly used in power engineering, communication engineering, electrical engineering, the dedicated ascending tool such as hydroelectric project, and appearance is new
Grain husk, it is beautiful and generous, have it is non-conductive, it is corrosion-resistant, resistance to it is dry and decayed, resistance to fade, be high-strength, lightweight, the features such as saturating magnetic pole is good, it good
Insulation feature ensure that the life security of worker to the greatest extent, but insulating ladder currently on the market is mostly common glass reinforced plastic
Composite structure, length are fixed, and when for higher power equipment maintaining, generally require to replace higher insulating ladder, therefore improve ladder
The storage level of son, while the also carrying not convenient for transportation greatly of too long ladder occupied space.
Summary of the invention
The purpose of the present invention is to provide a kind of portable ladder type insulated platforms, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the invention provides the following technical scheme:
A kind of portable ladder type insulated platform, including vertical bar, two vertical bars are symmetrical set, and the vertical bar upper end is equipped with secondary perpendicular
Bar, two subvertical tops insulated platform by hinge leaf connect, formed double ladder main structure, the vertical bar bottom is set
There is insulator foot, non-slip mat is equipped with below the insulator foot, limited support is equipped in the middle part of the vertical bar, wherein the vertical bar
Corresponding subvertical position is equipped with sliding slot, and the subvertical is inserted in sliding slot, is equipped with pulley close to top in the vertical bar, described perpendicular
It is equipped with take-up reel close to bottom in bar, the subvertical bottom is equipped with rope, and the rope connection pulley to take-up reel is described perpendicular
Corresponding take-up reel position is equipped with bearing outside bar, and the bearing is equipped with hand crank, is equipped with card structure, the limit in the limited support
Left side central portion is set there are two spring in supportting, and the spring one end is fixed in limited support inner left wall, and one end is fixed on card structure；
The bottom end of the vertical bar is rotatablely connected the engaging lug of antiskid plate side welding by pin shaft, and the bottom end of vertical bar is hemispherical junction
Structure, and corresponding antiskid plate upper surface opens up arc groove, hemispherical dome structure contacts setting with arc groove, the antiskid plate
Lower end surface is bonded with two pieces of rubber pads disposed in parallel, and the ladder of two pieces of rubber pads disposed in parallel and vertical bar composition by glue
The direction that minor structure is opened is vertically arranged, and for improving stability, and is provided between two pieces of rubber pads multiple towards vertical bar composition
The inclined hangnail of ladder structure opening direction, hangnail is welded on the lower end surface of antiskid plate.
Further, the bar of trampling with anti-skid chequer, anti-skid chequer are evenly arranged between two vertical bar and two subverticals
Fortuitous event is caused to be sent out for enhancing sole and trampling the frictional force of bar, while being also prevented to trample easy foot in the wet and slippery situation of bar and slide
It is raw.
Further, the vertical bar two sides are respectively equipped with hound, and hound is used for consolidating between insulator foot and vertical bar
It is fixed, promote the overall structure stability of ladder type insulated platform.
Further, wherein the limited support is hollow structure, convenient card structure is received during trampling bar rise and fall
Enter in limited support, does not influence the using effect for trampling bar.
Further, subvertical bottom position is corresponded in the vertical bar and is equipped with sedimentation limited block, is prevented secondary in use process
Vertical bar decrease speed is too fast directly to cause insulator foot to damage with insulator foot collision.
Further, the subvertical bottom is equipped with subvertical limited block, prevents user of service to subvertical ceiling
It cannot accurately hold, subvertical is caused to deviate to cause fortuitous event out of vertical bar.
Compared with prior art, the beneficial effects of the present invention are: this practical sleeve by upper and lower major-minor ladder is gone up and down, not only
The demand that traditional double ladder is ascended a height is met, ladder height can also be adjusted according to working depth, facilitate the work of personnel
Make, when not in use, the space occupied area can be greatly reduced, while also facilitating and being transported in the secondary main ladder of ladder income
Defeated carrying；
Sheet is practical can also be by the hand crank outside shaking to tightening state, and hand crank drives the take-up reel rotation in main ladder, by
The effect of rope, secondary ladder are pulled on liter, and the card structure being arranged in the middle part of ladder under the force of a spring, when secondary ladder rises, is trampled
Bar push card structure takes in downwards in limited support the rising for not hindering secondary ladder, the protrusion when reaching proper operation position, on card structure
Position can then block support on trampling bar, and personnel carry out operation at this time；When not in use, external hand crank is shaken to loosening shape
State, by the gravity of secondary ladder, secondary ladder will be fallen into main ladder, be trampled bar push card structure at this time and taken in limited support upwards, not shadow
The limited block for ringing and falling, while being arranged in major-minor ladder can be effectively prevented caused by ladder rises excessively and slip, while ladder bottom
The hound of portion's setting expands the bearing area of ladder, substantially increases the stability of ladder, while ladder is erected at insulation
On pedestal, insulation requirements when livewire work are met.
