Abstract
The utility model discloses an auxiliary tool for replacing an outdoor T-shaped fuse, and relates to the technical field of electric power overhaul tools. The auxiliary tool comprises a screw rod, a supporting frame, a sleeve head and an adjustable flexible fastening belt. The screw rod penetrates through a screw hole in the supporting frame and is movably connected with the sleeve head, a sleeve hole with the inner diameter matched with a fuse outer shell is formed in the sleeve head, and the adjustable flexible fastening belt is fixedly connected to the two ends of the supporting frame through two flexible connection belts. The auxiliary tool is simple in structure and flexible in operation, the fuse can be quickly and conveniently mounted and dismounted, the fuse outer shell can be precisely pressed to prevent the phenomenon that a spring props the fuse outer shell out, potential damage of the fuse due to falling is avoided, and the purpose that mounting and dismounting save time and labor and are safe and reliable is achieved.
Description
Technical field
The utility model relates to electric power overhaul technical field of tools.
Background technology
Current outdoor 35kV high-voltage insurance body is apart from ground 4-5m, is fastened on and supported on porcelain vase by sleeve pipe retainer ring, work high above the ground face is liftoff about 3m, and insurance both sides connect PT and bus by connecting line.35kV high-voltage insurance body is in the time of normal mounting position, and inner both sides spring is in compressive state.While changing operation at the scene, because the intrinsic spring force of insurance is very large, the single end cap that cannot make in high-altitude reaches normal mounting position, and because of the restriction of the scope of operation, cannot realize the one-sided many people operation in high-altitude, causes insurance body cannot assemble in high-altitude.Insurance body must be dismantled to ground, the auxiliary spring force of offsetting of a people, people's dismounting insurance body, completes the replacing of protective tube.Therefore this insurance often needs to expend a large amount of time in replacing, and easily causes insurance body to damage.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of outdoor T-shaped fuse replacement aid, simple in structure, flexible operation, the insurance of dismounting efficiently and easily, and can accurately compress insurance shell, prevent that spring handle insurance shell from ejecting, avoid the hidden danger that drops and damage, reach time saving and energy saving, the safe and reliable object of dismounting.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of outdoor T-shaped fuse replacement aid, comprise screw mandrel, bracing frame, pullover and adjustable flexible restraint zone, described screw mandrel is flexibly connected with pullover through the screw in the middle of bracing frame, this is pullover is provided with the trepanning that internal diameter and insurance shell match, and adjustable flexible restraint zone is connected and fixed by two flexible link belts and bracing frame two ends.
Preferably, described flexible connection adopts universal drive shaft to connect.
Preferably, described adjustable flexible restraint zone and flexible link belt are woven belt.
Preferably, described adjustable flexible restraint zone is belt fastener adjustment structure.
Preferably, the free end of described screw mandrel is provided with handle.
Preferably, described screw mandrel is full thread structure.
The beneficial effect that adopts technique scheme to produce is: this instrument utilizes adjustable flexible restraint zone to be fixed on insurance shell, utilizes screw mandrel to rotate pullover compression insurance shell, and screw mandrel is flexibly connected and makes compacted position more accurate with pullover employing; Adjustable flexible restraint zone is fastening, flexible link belt is and is flexible coupling, and screw mandrel and pullover between be flexibly connected, make operation more flexible, be not subject to the restriction of locus.
Utilize this instrument dismounting efficiently and easily insurance, and can accurately compress insurance shell, prevent that spring handle insurance shell from ejecting, avoid the hidden danger that drops and damage, make dismounting operation time saving and energy saving, safe and reliable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1, flexible link belt; 2, pullover; 3, bracing frame; 4, screw mandrel; 5, handle; 6, trepanning; 7, adjustable flexible restraint zone; 8, belt fastener.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The replacing of current outdoor 35kV insurance need two people to carry out, and limited space on framework cannot provide two people safety work simultaneously simultaneously.At present, mainly adopt a people to change, a people is auxiliary, due to the particularity of outdoor 35kV insurance, changes and often needs to expend a large amount of time, and easily cause damage.The utility model is on the basis of existing technology, holds for overcoming when existing T-shaped insurance is difficult for changing and changes the improvement that caducous deficiency is carried out.
Structure of the present utility model as shown in Figure 1, adopt the screw mandrel 4 energy full adjustment strokes of full thread structure, screw mandrel 4 is flexibly connected with pullover 2 through the screw in the middle of bracing frame 3, pullover 2 trepanning 6 matches with insurance shell, adjustable flexible restraint zone 7 links together by two flexible link belts 1 and bracing frame 3 two ends, make operation more flexible, be not subject to the restriction of locus.
Described flexible connection adopts universal drive shaft to connect or is hinged; Described adjustable flexible restraint zone 7 and flexible link belt 1 are woven belt, and described adjustable flexible restraint zone 7 is belt fastener 8 adjustment structures, simple in structure, be easy to fastening adjustment, make field-strip more flexible.
The handle 5 that the free end of described screw mandrel 4 arranges, facilitates rotary screw 4 operations.
When concrete operations, first pass through to regulate belt fastener 8 fastenings on outdoor insurance porcelain urceolus adjustable flexible restraint zone 7, pullover 2 are pressed on the shell of insurance one end, and rotary screw 4 compresses insurance, insures shell and falls in trepanning 6, screws out screw mandrel 4.
The concrete advantage of implementing: adopt this new utility model can conveniently change outdoor 35kV insurance, and can one man operation, the replacing time shortened to average 0.5 hour by average 2.5 hours before.
