The preferred material of insulated platform body 1 is glass-felt plastic, and guide rail 3 preferred material is aluminum alloy, and the preferred material of assembly pulley, support pulley 9 and pulley chain 10 is nylon pulley.Wherein, glass-felt plastic, i.e. epoxy glass stringing, add peptizer primarily of glass woven fabric and epoxy resin and form, its density is 1.5-2.0, lighter than steel 3-4 times, and intensity is higher than steel 1.7 times, and therefore, mechanical characteristics and physical property are all good.Diameter is the glass fibre of 10 microns, tensile strength is 3600 MPas, be equivalent to bear on the sectional area of every square millimeter 360 kilograms pulling force and constantly, except intensity height, the plurality of advantages such as quality is light, anticorrosive, insulation, easy to clean that it has.Therefore, glass steel material is adopted to make insulated platform most suitable.Pulley chain 10 required for the adjustment of platform left and right directions and dead sheave 9 and the Guide rollers needed for lifting platform 7 and lifting pulley 8 are nylon material, have that intensity is high, insulativity, lightweight feature.The guide rail 3 of lifting mode rail insulation operation platform have employed aluminum alloy material, and its density is low, but intensity ratio is higher, close to or exceed high-quality steel, and the good non-corrodibility of plasticity is good.
Lifting mode rail insulation operation platform of the present invention uses flow process as follows:
First, by electrician in electric pole appropriate location, work in coordination and fix chain 11 and pulley chain 10 by tightening up metal, platform mobile device is mounted on electric rod column, and oscilaltion device is dropped to bottom, and then work in coordination by insulated platform body 1 combination be mounted to insulated platform support 2 and guide rail 3 etc. form mobile device on, by bolt and nut fixation.
Wherein, the sway device of lifting mode rail insulation operation platform of the present invention, by metal fix chain 11, pulley chain 10, support pulley 9 coordinate, mobile device and insulated platform body 1 are fixed on electric rod column.It is fixed by insulated platform when hot line work that metal fixes chain 11 Main Function, prevents its left-right rotation.Now pulley chain 10 and support pulley 9 and electric rod column close contact, plays the effect supporting whole insulated platform.And when insulated platform needs left and right adjustment direction, only metal need be fixed chain 11 slightly just can adjust after pine, now pulley chain 10 and support pulley 9 and electric rod column still close contact, not only play the effect supporting whole insulated platform, can also make insulated platform can left and right adjustment direction and insulated platform can not be made to glide, after adjustment, tighten up sway device just serve fixation again, simple and effective.
The insulated platform body 1 that electrician enters lifting mode rail insulation operation platform carries out hot line work, and No. two electricians, to lifting mode rail insulation operation platform place beneath, adjust the hot line work position of an electrician by adjustment oscilaltion device.
When needs oscilaltion adjusts, push lifting limiting device 6 aside, rotate worm gear device 4 and drive lifting pulley 3 to rotate, tighten up or loosen lifting rope 5, insulated platform support about 2 is adjusted.Close lifting limiting device 6 to prevent platform maloperation after adjustment.When adjusting oscilaltion position, 6 Guide rollerses 7 are had due to what clamp guide rail 3,2, its middle and upper part Guide rollers 7 is installed on inside guide rail 3, bottom is totally 2 to 4 Guide rollerses 7, often pair of Guide rollers 7 is installed on the inside and outside with high side of guide rail 3 respectively, clamping while guide rail 3 facilitates oscilaltion, the effect of stable insulation platform can be played.2 Guide rollerses 7 of guide rail 3 upper inner bear the downward pulling force of insulated platform simultaneously, 2 Guide rollerses 7 of guide rail 3 lower outside bear the downward pressure of insulated platform, and all downward pulling force and pressure all conduct to guide rail 3 by Guide rollers 7 and is applied on electric rod column.The use of oscilaltion device, makes an electrician be in all the time within the scope of the available protecting of fence 1-1 when hot line work, avoids the operational method of trampling on fence 1-1 because operation height is inadequate.
Hot line work is complete, and after fence insulated platform drops to bottom, an electrician departs from insulated platform, and No. two electricians work in coordination and dismantle lifting mode rail insulation operation platform, and dismounting flow process is contrary with installation procedure.
