Abstract
The utility model relates to the device that power industry clamps for the U-shaped winding of instrument transformer, it by support body, screw mandrel, turn round rod, bearing, clamp assembly form, support body is provided with screw mandrel; Screw mandrel is connected with clamp assembly by bearing; Turning round rod is arranged on screw mandrel, and described clamp assembly at least forms by two; Owing to being provided with neonychium in chuck, thus effectively protect the outer surface of winding when clamping; Be provided with skid resistant course owing to turning round rod, thus guarantee when clamping that operating personnel hold with a firm grip and turn round excellent uniform force application; Be provided with stop nut owing to turning round rod, thus ensure that turn round rod not easily drops on screw mandrel; Owing to being provided with bearing, thus reduce the friction between holder and screw mandrel, guarantee that holder can not follow rotation because screw mandrel rotates, make the chuck on holder and winding keep relative illegal state, protect winding outer surface further; Due to rational in infrastructure, easy to use, so there is very large practical and popularizing value.
Description
Technical field
The utility model relates to when power industry is installed for instrument transformer winding and clamps shaping device, the specifically U-shaped winding clamping apparatus of a kind of instrument transformer.
Background technology
Through retrieval Patent documents of interest, not yet retrieve a kind of instrument transformer U-shaped winding clamping apparatus for instrument transformer U-shaped winding installed identical with the utility model structure at present.When the U-shaped winding of existing power industry to instrument transformer is installed, need first U-shaped winding to be clamped shaping, the method that staff generally adopts rope to tie up is installed after making U-shaped winding shaping, these class methods are not only time-consuming but also require great effort, and while use rope is tied up U-shaped winding, rope is in the mantle friction of winding, the surface of winding is made to cause damage, thus U-shaped winding can not normally use, cause serious economic loss, so be necessary to design the U-shaped winding clamping apparatus of a kind of instrument transformer, make high-quality, the U-shaped winding of each instrument transformer is installed rapidly, to enhance productivity, reduce the labour intensity of staff.
Summary of the invention
The purpose of this utility model will provide a kind of to protect U-shaped winding clamping in process, improves the installation effectiveness of the U-shaped winding of instrument transformer, reduce the U-shaped winding clamping apparatus of a kind of instrument transformer of labour intensity.
Technical characteristic of the present utility model is: install in consideration, easy to use, the basis that bulk strength is high is designed to by support body, screw mandrel, turns round rod, the U-shaped winding clamping apparatus of a kind of instrument transformer that bearing, clamp assembly form, and support body is provided with screw mandrel; Screw mandrel is connected with clamp assembly by bearing; Turning round rod is arranged on screw mandrel, described clamp assembly at least two.
The described outer surface turning round rod is provided with skid resistant course, and two ends are respectively equipped with stop nut.
Described clamp assembly is made up of holder, chuck, neonychium, and chuck is packed on holder; Neonychium is arranged in chuck; Described chuck is a semi-circular ring adopting metal material to make, and the concave profile of its semi-circular ring and the outer arcuate face of U-shaped winding match, and are convenient to U winding in chuck inner position; Described neonychium for adopt rubber, nylon wherein a kind of material make and match with chuck.
During use, rod is turned round in rotation, screw mandrel drives two chucks to be flared to suitable distance, the exterior arc surface of the inner arc surface of chuck and U-shaped winding is fitted, rotary screw rod turns round rod, screw mandrel rotary motion, under the effect of bearing, two chucks do relative movement, thus clamp shaping by U-shaped winding, are convenient to the installation of later process.
The utility model has the advantages that: owing to being provided with neonychium in chuck, thus effectively protect the outer surface of winding when clamping; Be provided with skid resistant course owing to turning round rod, thus guarantee when clamping that operating personnel hold with a firm grip and turn round excellent uniform force application; Be provided with stop nut owing to turning round rod, thus ensure that turn round rod not easily drops on screw mandrel; Owing to being provided with bearing, thus reduce the friction between holder and screw mandrel, guarantee that holder can not follow rotation because screw mandrel rotates, make the chuck on holder and winding keep relative illegal state, protect winding outer surface further; Due to rational in infrastructure, easy to use, so there is very large practical and popularizing value.
