Abstract
The utility model provides a transformer high-tension bushing cone fastening device which comprises a handle and a movable clamp, the top of the handle is provided with a fixed clamp, and the movable clamp is arranged on the handle and matched with the fixed clamp. The transformer high-tension bushing cone fastening device is characterized in that the movable clamp is arranged in a sliding sleeve on the handle, and a locking screw is arranged on the sliding sleeve. After the locking screw is conveniently unlocked, the sliding sleeve and the movable clamp can jointly and movably move in a reciprocating mode along the handle to be in the required opening size, then the sliding sleeve and the movable clamp can be fixed on the handle through the locking screw, then the sliding sleeve can easily extend into a gap of a cone flange, and fixation of a cone threaded rod is achieved; the opening size between the fixed clamp and the movable clamp can be adjusted at will according to requirements, the flange cannot be damaged during inward extending, the sealing performance of the flange is guaranteed, and meanwhile mendaciously-fastening conditions are avoided.
Description
Technical field
The utility model relates to a kind of fastener, and particularly a kind of transformer high-voltage bushing, by army cap fastener, belongs to fastened tools design and manufacturing technology field.
Background technology
Large-scale power transformer bushing top is commonly called as " by army cap ", and it is not only the only way which must be passed of high-tension current, but also is the necessary device of the interior transformer oil of transformer and extraneous seal isolation.In the transformer course of work, often there will be phenomenon loosening army cap, once and loosening can cause D.C. resistance to exceed standard and generate heat, can make moisture, Air infitration simultaneously and affect the quality of transformer oil, and then affect the safe and stable operation of electrical network and equipment thereof.At present transformer is carried out army cap when fastening, large size spanner need to be stretched into by army cap flange, and be connected on its screw rod and just can be fixed.Because the gap between flange is less, when large size spanner stretches into, time-consuming effort again, careless slightly, can make flange damage and reduce its sealing property.In addition, the spanner stretching into easily causes empty tight situation, army cap is still loosening after causing spanner to be withdrawn from.Therefore be necessary prior art to be improved.
Summary of the invention
Existing when terminal operation is carried out to by army cap in bushing shell for transformer top for solving, can only adopt large size spanner to be fixed its screw rod, easily cause the problem that army cap damage is affected to its sealing, the utility model provides a kind of transformer high-voltage bushing by army cap special fastening device.
The utility model completes by following technical proposal: a kind of transformer high-voltage bushing is by army cap fastener, comprise the handle of the fixing pincers of its top band, and be located at the adjustable clamp coordinating with fixing pincers on handle, it is characterized in that adjustable clamp is placed in the sliding sleeve on handle, sliding sleeve is provided with lock-screw, to move back and forth along handle together with adjustable clamp by sliding sleeve, thereby adjust the distance between fixing pincers and adjustable clamp, complete by the clamping of army cap screw rod.
Described sliding sleeve is provided with longitudinal hole, handle is placed in longitudinal hole, longitudinal hole outside is provided with horizontal screw, this horizontal screw is communicated with longitudinal hole, in horizontal screw, be provided with lock-screw, longitudinal hole inner side is made as up big and down small taper hole, adjustable clamp is made as up big and down small cone pincers, adjustable clamp bottom is placed in the taper hole of sliding sleeve inner side, to unclamp lock-screw, sliding sleeve is moved back and forth to required opening size along handle together with adjustable clamp, then by lock-screw, sliding sleeve, adjustable clamp are fixed on handle.
Described fixing pincers lower surface is provided with the sawtooth matching with adjustable clamp upper surface, and adjustable clamp upper surface is provided with the sawtooth matching with fixing pincers lower surface.
The thickness of described handle, fixing pincers and adjustable clamp is made as 5 ~ 8mm, stretches in the ring flange gap of army cap, thereby complete fixing army cap screw rod to facilitate.
The utlity model has following advantages and effect: adopt such scheme, can unclamp easily after lock-screw, sliding sleeve is moved back and forth to required opening size along handle together with adjustable clamp, by lock-screw, sliding sleeve, adjustable clamp are fixed on handle again, thereby stretch into like a cork in the gap of army cap ring flange, complete fixing army cap screw rod, can adjust arbitrarily as required the opening size between fixing pincers and adjustable clamp, can in the time stretching into, not cause damage to flange again, guarantee the sealing of flange, avoided the appearance of empty tight situation simultaneously.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the right view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As Fig. 1, Fig. 2, the transformer high-voltage bushing that the utility model provides is by army cap fastener, comprise the handle 2 of the fixing pincers 1 of its top band, and be located on handle 2 with fixing pincers 1 adjustable clamp coordinating 5, adjustable clamp 5 is placed in the sliding sleeve 3 on handle 2, sliding sleeve 3 is provided with lock-screw 4, wherein: sliding sleeve 3 is provided with longitudinal hole, handle 1 is placed in longitudinal hole, longitudinal hole outside is provided with horizontal screw, this horizontal screw is communicated with longitudinal hole, in horizontal screw, be provided with lock-screw 4, longitudinal hole inner side is made as up big and down small taper hole, adjustable clamp 5 is made as up big and down small cone pincers, this cone pincers bottom is placed in the taper hole of sliding sleeve 3 inner sides, fixing pincers 1 lower surface is provided with the sawtooth matching with adjustable clamp 5 upper surfaces, and adjustable clamp 5 upper surfaces are provided with the sawtooth matching with fixing pincers 1 lower surface, the thickness of handle 2, fixing pincers 1 and adjustable clamp 5 is made as 5 ~ 8mm, to unclamp lock-screw 4, sliding sleeve 3 is moved up and down to required opening size along handle 1 together with adjustable clamp 5, by lock-screw 4, sliding sleeve 3, adjustable clamp 5 are fixed on handle 1 again, stretch in the ring flange gap of army cap to facilitate, thereby complete fixing army cap screw rod.
