Specific embodiment
In the present embodiment, as depicted in figs. 1 and 2, a kind of electric power tower maintenance portable working platform includes: supporting part
Part 1, support member 2, guardrail 3, suspension member 4 and fixation member 5；
Load bearing component 1 is made of n=3 block plate, and adjacent two plates are linked by hinge, the upper end of three blocks of plate
Face is evenly distributed with non-slip texture；So set, three blocks of plates can be fixed by hinge, and the plate on both sides can pass through conjunction
Page is rotated, and is folded together, and has decorative pattern on plate, and people stands on plate, it is possible to increase frictional force prevents people from slipping.
In specific implementation, the n block plate of load bearing component 1 is carbon fibre material, plate with a thickness of 10mm~15mm, this
Embodiment is preferably 10mm.This is because carbon fibre material intensity is more much higher than general aluminium intensity, and lighter weight.This
The carbon fiber sheet of thickness can bear at least 500 kilograms of weight without fractureing.
The material of the n block plate of load bearing component 1 can also be aluminium, plate with a thickness of 15mm~20mm, the present embodiment is excellent
It is selected as 6mm.The aluminium sheet of this thickness can bear at least 500 kilograms of weight without fractureing.
The hinge material of load bearing component 1 can also be steel alloy, hinge with a thickness of 5mm~10mm, this hinge can be born
At least 500 kilograms of weight is without fractureing.
The material of support member 2 is aluminium or carbon fibre material, and has reeded plate by two pieces of middle parts and constitute, two pieces
Plate is mutually perpendicular to constitute L-shaped structure and forms its " L " type bound edge by the side that groove is fixed on load bearing component 1；And it holds
The end that load component 1 and support member 2 surround has notch, so set, the indentation, there accommodates the vertical supporting beam of steel tower.
Support member 2 plays the role of improving load bearing component intensity and fixed load bearing component.
As shown in figure 3, guardrail 3 is made of two support column 3-1 and extension type flase floor 3-2, and pass through two supports
Column 3-1 is fixed in support member 2；Extension type flase floor 3-2 is provided between two support column 3-1, thus without " L "
Barrier structure is formed on the load bearing component 1 of type pack edge；Extension type flase floor 3-2 be sequentially connected by several telescopic units and
At the both ends extension type flase floor 3-2 are fixed on two support column 3-1, and each telescopic unit is by two length with a thickness of 5mm
The connecting rod 3-2a of bar shaped intersects placement, and is fixed at crossing center by pin shaft 3-2b, and the material of connecting rod 3-2a is carbon
Fiber, in the upper end of load bearing component 1, the both ends of connecting rod 3-2a also have through-hole, the latter telescopic unit and previous flexible list
The connection of member, fixes realization with pin shaft 3-2b by the through-hole at the both ends connecting rod 3-2a, i.e., passes through between two neighboring telescopic unit
The pin shaft 3-2b at both ends is fixed；So that extension type flase floor 3-2 is shrinkable and elongates；Such structure setting, guardrail is convenient for folding
It is stacked together, it is easy to carry, space is saved, and guardrail plays the purpose of protection construction personnel, if protecting without guardrail, personnel are being held
Carry astasia on component, it is possible to fall from load bearing component, damage to personnel.And this structure is solid relative to other
The guardrail that plate surrounds has light weight, with the few advantage of material.In specific implementation, the height of guardrail 3 is in 0.8m~1.5m, originally
Embodiment is preferably 1m, this highly can effectively protect personnel, and height is too high, and waste material and occupied space, height is too low, is risen not
To the purpose of protection staff.There are two guardrails 3, is separately fixed at the hanging two sides of load bearing component 1.This is because load bearing component
Other two sides all have the supporting beam on steel tower, play the role of similar guardrail and protect, there is no need to be further added by guardrail.Specifically
In implementation, also there is photosensitive LED light strip on guardrail 3, may make this operating platform that there are illumination functions, it can be in night operation.
As shown in figure 4, suspension member 4 is made of wirerope 4-1, hanging ring 4-2, hook 4-3 and supporting block 4-4, hanging ring 4-
2 one end is equipped with screw thread and is fixed on supporting block 4-4, and the hanging ring 4-2 other end is circular ring structure, and one end of wirerope 4-1 is worn
The annulus of hanging ring 4-2 is crossed, the other end connection hook 4-3, hook 4-3 of wirerope 4-1 is used to be articulated to the crossbeam of steel tower, branch
There is through slot inside bracer 4-4, and be embedded in one end of load bearing component 1, to suspend load bearing component 1 in midair；Suspension member is set, greatly
The stress condition for improving load bearing component greatly, so that load bearing component uniform force.
As shown in figure 5, fixation member 5 is made of connecting pin 5-1 and woven belt 5-2, load bearing component 1 is placed on support member
After on 2, the load bearing component 1 that connecting pin 5-1 passes through the two plates of support member 2 and is embedded in the groove of plate will be carried
Component 1 is fixed, and prevents load bearing component 1 mobile, one end of connecting pin 5-1 is threadedly secured to " L " of load bearing component 1
On type bound edge, the other end of connecting pin 5-1 is circular ring structure, and woven belt 5-2 passes through the annulus of connecting pin 5-1, passes through woven belt
5-2 will be in whole operation platform binding and fixing to steel tower.In specific implementation, the annulus end court of the connecting pin 5-1 of fixation member 5
Downwards, and highly exceed the beam thickness of steel tower, pass through connecting pin 5-1 convenient for woven belt 5-2 and bind on the crossbeam of steel tower；
Fixation member 5 plays the role of fixed load bearing component and whole operation platform is fixed on steel tower.
Working principle of the present invention is as follows: usually, to together, guardrail 3 also folds into three pieces of folded sheets of load bearing component 1
Together, folded load bearing component 1 and guardrail 3 are put together with suspension member 4, support member 2 and fixation member 5.
As shown in fig. 6, in use, the two plates of support member 2 are mutually perpendicular to be installed to the two sides of load bearing component 1,
Then load bearing component 1 is fixed in support member 2 by fixation member 5, suspension member 4 is installed the one of support member 2
End, by suspension member 4 by after fixation load bearing component 1 and support member 2 draw arrive steel tower designated position, 1 He of load bearing component
For one end notch of support member 2 against the vertical supporting beam of steel tower, the two plates of support member 2 are respectively erected in steel tower
On crossbeam, then by the woven belt 5-2 in fixation member 5, load bearing component 1 and support member 2 are fixed on steel tower, then will
The hook 4-2 of suspension member 4 is hung in the supporting beam of steel tower, then installs two guardrails 3 in the upper end of load bearing component 1, guardrail 3
Tensile elongation is adjusted according to the size of load bearing component 1.So, the installation of operating platform is just completed.Operator can incite somebody to action
Construction equipment is placed on load bearing component 1, and operator can stand and construct on load bearing component 1.The operating platform of the present embodiment can
Bear 500 kilograms of weight and not broken.
A kind of electric power tower maintenance another preferred embodiment of portable working platform, with a kind of upper embodiment base
This is identical, only difference is that, the material of three blocks of plate of the load bearing component 1 replaces with aluminium, the thickness of plate by carbon fiber
Degree is 15mm~20mm.The present embodiment is preferably 15mm.This operating platform can bear 500 kilograms of weight and not broken.
