The bottom end of each support hanging element (1) is connected on the foot treadle (4) through a bolt. Top ends are provided with bending sections (5), and gum covers are covered on the bending sections (5). A length adjusting strip (3) and a stabilizing strip (7) are connected between the two support hanging elements (1).
Description
Technical field
The utility model relates to a kind of insulator string of strain tower in UHV transmission line suspension type adjustable lifting platform, is applicable to that spacing is wide, the upkeep operation on the strain insulator string of distance.
Background technology
At present, increase day by day along with the China Power demand, at a distance, large capacity, UHV transmission line have become the high-speed channel that electric power is carried, along with putting into operation of UHV transmission line, the traditional work mode of former 500kV transmission line can not meet the demand of Maintenance of Electric Transmission Line, maintenance on the strain insulator string of ultrahigh voltage transmission line of long distance, wide spacing.In prior art, a kind of method is that the operating personnel rides and climbs on an insulator string bowl head, at height, by health, keeps balance in the air; Another kind is that operating personnel's both feet step down in respectively on two insulator string bowl heads, and upkeep operation is carried out in the action of similar squat.
Implement said method and have following difficulty: 1, because the spacing of extra high voltage line strain tower insulator string wider (1m), length are grown (13m), transmission line is with the fluctuating difference of landform, between steel tower, thereby the insulator hanging point exists the discrepancy in elevation to cause that the strain tower insulator string arranges installation with inclination angle along hillside, if staying on insulator string for a long time, the operating personnel carries out upkeep operation, repair materials, instrument heavier (15kg-20kg) are incited somebody to action greatly loss operating personnel's muscle power in addition, thereby easily cause accident to occur.2, the operating personnel adopts said method on insulator string, to carry out operation, can not carry out efficiently replacing insulator work, and operating efficiency is low.
Summary of the invention
For solving the problems referred to above of prior art, the purpose of this utility model be to provide a kind of on UHV transmission line strain tower insulator string the adjustable lifting platform, can assist the work high above the ground personnel on the strain insulator string of long distance, wide spacing, to complete the mobile assistance platform of the upkeep operations such as monolithic insulator replacing, insulator cleaning, the close collection of insulation alite, alleviate work high above the ground personnel's labour intensity and task difficulty, increase work efficiency, guarantee simultaneously the safety of work high above the ground personnel in the upkeep operation process.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of on strain insulator string of ultrahigh voltage transmission line the adjustable lifting platform, the utility model is characterised in that, comprises pedal and is connected to the support suspension member at pedal two ends; Support suspension member and be divided into two of left and right, the every bottom of supporting suspension member is connected on pedal with bolt, and top is provided with a bending section, is provided with gum cover and is enclosed within on bending section; At two, support between suspension member and be connected with length adjustment bar and firm bar.
The utility model vertically offers one and teases and ridicule knothole on the support suspension member, length adjustment bar two ends are by the inclination angle that is connected to adjust pedal with the different adjustment hole.
Operation principle and the process of described platform are:
1, the work high above the ground personnel carry and transmit rope and enter into UHV transmission line strain tower insulator string maintenance face, and the Ground Operation personnel are delivered to maintenance face to platform, the high-altitude personnel the support suspension member card of platform surely on two insulator string bowl heads.
2, after installing and supporting suspension member, the work high above the ground personnel step down on the pedal of platform and are loaded on fixed head, thereby platform is not rocked back and forth, and reach firm purpose.By pedal, the operating personnel is well stood, and can vacate both hands and on insulator, carry out work in every.
The technique effect that the utility model reaches:
1, described platform, as the Work tool of operation on strain insulator string, its security performance meets the requirement of electric power safety working regulation, can effectively improve the coefficient of safety of work high above the ground personnel while overhauling.
2, usage platform operation on insulator string, can safety, efficiently finish the work, increase work efficiency, alleviate operating personnel's labour intensity.
3, adopt the aluminum alloy materials casting, deadweight 15kg, rated load 200kg, carry out 2.5 times of running tests, and without deformation and damage, mechanical strength meets electric power instrument general technical specifications standard.
4, by platform, can on insulator string, complete fast the operations such as replacing insulator and the close collection of salt.

Embodiment
Below by drawings and Examples, the technical solution of the utility model is further described.
Contrast Fig. 1 to Fig. 3, a kind of on strain insulator string of ultrahigh voltage transmission line the adjustable lifting platform, the utility model is characterised in that, comprises pedal 4 and is connected to the support suspension member 1 at pedal 4 two ends; Support suspension member 1 and be divided into two of left and right, the every bottom of supporting suspension member 1 is hinged and connected on pedal 4, and top is provided with a bending section 5, is provided with gum cover 2 and is enclosed within on bending section 5; At two, support between suspension member 1 and be connected with length adjustment bar 3 and firm bar 7.
The utility model vertically offers one and teases and ridicule knothole 6 on support suspension member 1, length adjustment bar 3 two ends are by the inclination angle that is connected to adjust pedal 4 with different adjustment hole 6.
The utility model course of work and principle are: as shown in Figure 1, according to insulator string inclination situation, with length adjustment bar 3 and support suspension member 1, make up.
Support the termination of suspension member 1 bending section 5 and block insulator bowl head, thereby can fix platform, be beneficial to personnel's work.
Support two tops of suspension member 1 bending section 5 and entangle with gum cover 2, the frictional force in the time of can increasing whole bracing frame and contact with insulator bowl head, prevent the slip of bracing frame front and back.Adjustment hole 6 is be used to regulating two length that support suspension members 1, pedal 4 is suspended on the insulator string of inclination and also can remains on horizontal plane.
Whole bracing frame is provided with firm bar 7, and its effect is to make operating personnel's stable support suspension member when crossing insulator string, prevents from supporting suspension member and horizontally slips.
The concrete operation method step is as follows:
1, the ground staff is according to the insulator string situation that tilts, on ground length adjustment bar 3 with support suspension member 1 and assemble.
2, the work high above the ground personnel carry and transmit rope and enter into UHV transmission line strain tower insulator string maintenance face, and the Ground Operation personnel are delivered to maintenance face to platform, the high-altitude personnel the support suspension member 1 termination card of platform surely on two insulator string bowl heads.
3, after installing and supporting suspension member, the work high above the ground personnel step down on the pedal 4 of platform and buckle firm bar 7 again.By pedal, the operating personnel is well stood, and can vacate both hands and on insulator, carry out work in every.
