Abstract
The utility model provides an attachment water-cooling electric high-frequency vibrator under a plurality of improvements. The prior high-frequency vibrator has the problems that the structure is complex; the service life is short; and the stator windings are needed to be repaired and replaced frequently, thereby impacting production and increasing cost. On the basis of the prior attachment electric high-frequency vibrator, the utility model has the characteristics that the housing of the vibrator is double-layered; and the middle part of the housing is cooled by water. Therefore, the temperature of the housing of the vibrator is greatly reduced; the service life of the vibrator is prolonged; the troubles of frequent repairing and stator winding replacement are avoided; the production efficiency is improved; and the use cost is reduced. Moreover, the tamping vibration intensity of the vibrator is increased by 20 to 30% than that of a general vibrator; the outer surface of the concrete is smooth after a tamping vibration; the bubbles and the shrinkage holes of the concrete are small and less; and the investment is saved by 5 to 6 times than a high-frequency vibrator with a variable-frequency power supply, so that the high-frequency vibrator is the most ideal high-frequency vibrator used at the external of concrete.
Description
One, affiliated technical field
The utility model relates to a kind of electric vibrator, especially relates to a kind of attached to the adhesion type water-cooling electric dither that on the concrete blinding concrete is carried out jolt ramming.
Two, background technology
Concrete in casting process in order to improve concrete casting quality and intensity, domesticly used a kind of novel attached electric dither, the patent No. is 01204859.3, this utility model has proposed a kind of the rotor axis of electric two ends to be manufactured the taper shape, and it is placed in attached electric dither in the bigger conical raceway (roll sleeve) that adapts with it.
This vibrator has overcome the patent No. 92244008.5 adhesion type dithers and has existed part many, complex structure, the malfunctioning problem of exciting; Also overcome the short circuit of the electronic dither stator winding insulation of patent No. 99232971.X and burnt problem.
Use proof; there is a very big deficiency in this novel high-frequency vibrator: use certain hour (about 20-30 minute) the excessive temperature rise of stator winding; must shut down cooling; influence work production; stator winding is shorter service life; to often repair replacing, make troubles, increase cost thus, lower efficiency.
Three, summary of the invention
In order to overcome above-mentioned deficiency, it is a kind of through after improving that the utility model provides, casing is inner with water-cooled adhesion type water-cooling electric dither, can effectively solve the excessive temperature rise of stator winding, can avoid often repairing and change the trouble that stator winding brings, improve vibrator works efficient, increase the service life.
The purpose of this utility model reaches by following measure: adhesion type water-cooling electric dither comprises internal layer casing, outer casing, sealing ring, stator, stator winding, rotor, end cap, supporting base, water pipe head.Stator and stator winding are contained in the internal layer casing, and conical raceway is housed in the supporting base, and supporting base is contained in internal layer casing and outer casing two ends.Lay armature spindle (together with rotor) in the conical raceway, the armature spindle two ends are conical shaft, its tapering and conical raceway adapt, the conical shaft diameter is than the little gap of conical raceway diameter, this gap has guaranteed conical shaft (rotor) rotation also revolution rolling in conical raceway simultaneously during energising, produces dither.Leave the gap between the end face of armature spindle two terminal circle diminished shaft and the end cap internal face, this gap has been avoided the friction between armature spindle two ends and the end cap internal face.
The casing that is characterised in that of the present utility model is designed to bilayer, form by internal layer casing and outer casing, internal layer casing and outer casing connect into an integral body with dividing plate, between inside and outside layer casing, form several gardens arc space of cutting apart by dividing plate, the garden arc space is communicated with one by one by the hole at place, dividing plate end, be convenient to the cooling water garden arc space of flowing through one by one in order, the internal layer casing is implemented cooling, reduce winding temperature rise.Stator and stator winding are contained in the internal layer casing, and the internal layer casing is surrounded by outer casing.The vibrator outer surface has water pipe head.All there is the sealing ring sealing on internal layer casing, outer casing and supporting base composition surface and supporting base and end cap composition surface, form a hermetic structure, can prevent effectively that cooling water flow is to the inside and outside portion of vibrator.During vibrator works, connect cooling water from water pipe head, cooling water flows out from another water pipe head after the mobile in order circulation in the arc space of garden.
Use proof, the beneficial effects of the utility model are: with the most simple and practical water-cooling method, by existing vibrator structure is done suitably to improve, make it can effectively solve the excessive temperature rise of vibrator stator winding and bring the trouble that often to repair replacing, but the vibrator continuous operation has improved service efficiency; Reduce stator temperature during use, prolonged the vibrator life-span, reduced use cost, produced beyond thought practical function and economic benefit.
