The invention relates to an insulated angle lifting platform for live working. The insulated angle lifting platform comprises a movable base, support rods fixed on the base and a frame arranged on the support rods and is characterized in that two rectangular frames, namely an inner frame and an outer frame which have a similar shape are composed of longitudinal beams, transverse beams and upright columns, wherein each longitudinal beam is made of a sectional bar with a groove on the cross section, and the inner frame is inserted into the outer frame to form a telescopic frame by mutually buckling the grooves of the longitudinal beams of the inner frame and the outer frame. A pulley is arranged on each of four transverse beams of the outer frame and each of upper and lower transverse beams at one end of the inner frame, an electric winding drum and a pulley are arranged on the base, a drawing rope from the electric winding drum sequentially passes through each pulley and then returns to the electric winding drum. Each of the longitudinal beams, the transverse beams and the upright columns is made of a section bar of an insulated epoxy resin material. The insulated angle lifting platform disclosed by the invention can be used for maintaining various equipments in a substation in an electrified manner and ensuring personal safety and equipment safety of working.
Description
Technical field
The invention belongs to electric power power transformation operation technical field, particularly the specific purpose tool of transformer station's live-line maintenance operation.
Background technology
Run in professional transformer station hotline maintenance process in electric power system power transmission and transformation, need specific purpose tool to carry out the upright switch of installation and repairing, rotary switch, isolating switch and dismounting bus leading streamline etc.Because substation equipment space is little, can not meet the air gap of live line working regulations stipulate, just necessary interruption maintenance, interruption maintenance causes large-area power-cuts, can cause power industry direct economic loss.Just need hotline maintenance process if do not had a power failure, but there is no the facility that can ensure live line working air gap and combinational gap at present.
Summary of the invention
In order to solve the problem not having suitable facility in transformer station's eminence live line working, following technical scheme is proposed.
A kind of live line work insulating angle hoistable platform, it comprises moveable base, the framework being fixed on the pole on base and being arranged on pole, its special character is by longeron, crossbeam and column form the similar cuboid frame of two shape of cross sections, be called inside casing and housing, its longeron is made up of the reeded section bar of cross section tool, by the mutual hasp of groove of interior housing longeron, inside casing is inserted in housing and form telescopic framework, center stand column is equipped with at the middle part of housing two sides, two center stand column are arranged on pole by axle, separately there is a tubular nut, the screw thread at its two ends is respectively left-handed and dextrorotation, a screw rod is respectively connected at the two ends of nut, one of them screw rod is hinged on the longeron of housing, another screw rod is hinged on base, each installation pulley on four crossbeams of housing and two crossbeams of inside casing one end, base is installed electric reel and a pulley, from electric reel stay cord out successively by getting back to electric reel after each pulley.One end of inside casing is provided with job platform.Described longeron, crossbeam and column are made by the section bar of insulating epoxy material.
This live line work insulating angle hoistable platform in use, the putting position of live line work insulating angle hoistable platform is determined according to the position of setting, rotating nut makes two screw rod specific elongations, the elevation angle (angle between framework and ground) of adjustment framework, by electric reel traction stay cord, inside casing is stretched out from housing again, namely the job platform of inside casing one end is raised to job position, like this, is convenient to the equipment of maintenance personal to eminence and overhauls.
Tool of the present invention has the following advantages
Use this live line work insulating angle hoistable platform, can the various equipment of power-on serving transformer station, determine air gap and combinational gap by regulatory requirements, ensure personal safety and device security, timely treatment facility defect, ensure the safe operation of equipment, and easy to use, operating efficiency is high.

Embodiment
Embodiment
A kind of live line work insulating angle hoistable platform, the framework that it comprises the fixing pole 8 on the base 3 of the base 3, two being provided with castor 2 and is arranged on pole 8.Framework comprises the similar cuboid housing of its shape of cross section and inside casing.Housing is formed by the first longeron 9, first crossbeam 17 and the first column 12; Inside casing is formed by the second longeron 13, second cross beam 16 and the second column 15.Job platform is provided with at the left end of inside casing.At the upper and lower surface of housing, first connecting rod 10 is all installed, at the upper and lower surface of inside casing, second connecting rod 14 is all installed.Connecting rod links the longeron of the left and right sides, is equivalent to the cross bar of insulating ladder.After this live line work insulating angle hoistable platform rises, operating personnel pedals this connecting rod can climb to upper end from lower end, to job platform work.The longeron of interior housing is made by the reeded section bar of cross section tool, and the shape of its cross section is see Fig. 4, and namely a rectangular limit is again to vertical direction bending after upwards extending, and forms a hook, forms groove between this hook and rectangle.Because the groove of interior housing longeron can hasp mutually, form telescopic framework so inserted in housing by inside casing, inside casing can slide along the groove of longeron, and namely this groove is equivalent to insulating slide.Be equipped with center stand column 20 at the middle part of housing two sides, two center stand column 20 are arranged on two poles 8 by axle 19, are placed in by whole framework between two poles 8, by whole frame installation on the base 3.Separately there is a tubular nut 5, the screw thread at its two ends is respectively left-handed and dextrorotation, respectively connects a screw rod 4 at the two ends of nut 5, and one of them screw rod 4 is hinged on the first longeron 9 of housing, another screw rod 4 is hinged on reference column 6, and reference column 6 is fixing on the base 3.Make the specific elongation of two screw rods 4 by rotating nut 5, reach the object at the adjustment framework elevation angle.First pulley 1 is installed on the base 3, first crossbeam 17 on housing right-hand member is installed the second pulley 22, first crossbeam 17 on housing left end installs the 3rd pulley 18, second cross beam 16 on inside casing right-hand member installs the 4th pulley 21, second cross beam 16 below inside casing right-hand member installs the 5th pulley 23, first crossbeam 17 below housing left end installs the 6th pulley 11, first crossbeam 17 below housing right-hand member installs the 7th pulley 24, from electric reel 7 stay cord 25 out successively by the first pulley 1, second pulley 22, 3rd pulley 18, 4th pulley 21, 5th pulley 23, electric reel 7 is returned after 6th pulley 11 and the 7th pulley 24.Electric reel 7 rotates traction stay cord 25 makes inside casing stretch out from housing.So-called electric reel 7 is made up of motor and a reel.Install four castors 2 below base 3, wherein two is universal wheel.
