Abstract
The utility model relates to an electric machine built-in insertion type concrete vibrator. A vibrating head is arranged at the front end in a rod-shaped casing, the interior of the vibrating head is provided with a rotation eccentric block which is supported by a bearing structure and is driven by an electric machine which is arranged in the casing, wherein, the electric machine in the casing is a permanent-magnet dc electric machine which is directly connected with the rotation eccentric block through an armature, and the armature is connected in the casing through a bearing structure. A brush carrier which can be used for providing current is connected with an external power supply through a connector and a wire connector which are arranged at the tail end of the rod-shaped casing.
Description
The utility model relates to a kind of immersible concrete vibrator, specifically is the inbuilt concrete vibrator of a kind of motor.
Employed immersible concrete vibrator has motor fitted outside and motor built-in type two classes in building operations at present.Used three-phase alternating-current motor is arranged at outside the vibrator in the motor fitted outside vibrator, drives the eccentric block that is arranged in the vibrating head through 4～6 meters long flexible axle flexible pipes and clashes into excellent shell generation vibration.Its running noise is big, and efficient is low, and labor intensity of operating personnel is big.Motor built-in type vibrator is owing to be arranged at drive motors in the housing of vibrator, though cancelled the flexible axle flexible pipe, though can overcome the shortcoming that the fitted outside running noise is big and use is inconvenient, but because of it must adopt the three-phase mid-frequency motor of 150～200Hz, must require to have special-purpose three-phase intermediate frequency power supply such as variable-frequency power generation unit or frequency-variable electronic device supporting with it, the inconvenient part of himself is also arranged.
The purpose of this utility model is according to above-mentioned situation, and a kind of improved motor built in type immersible concrete vibrator is provided, to overcome the weak point of existing this class motor built in type vibrator.
The utility model motor built in type immersible concrete vibrator is identical with the structural principle of existing like product, front end in its bar-shaped housing is a vibration head, be provided with in it through the bearing arrangement supporting, and can be by the motor-driven rotating eccentricity piece that is arranged in the housing.Wherein be arranged in the housing motor for directly be connected with armature with the rotating eccentricity piece permanent magnet DC motor, its armature is in bearing arrangement is connected in housing.Can be the connector of its brush carrier that electric current is provided through being positioned at bar-shaped housing tail end is connected with external power with electric wire connecting junction.Permanent magnet in the wherein said permanent magnet DC motor is to adopt respectively by the permanent magnet of watt N that the shape Nd-Fe-B permanent magnet is formed of several piece same polarity, a pair of utmost point of S to well.It is little that common alternating current is transformed to the required general volume of fairings such as bridge rectifier of direct current, weight is lighter, can be arranged at outside the vibrator and be connected with vibrator, also can directly this fairing be arranged in this electric wire connecting junction of said vibrator afterbody through lead.For ease of producing and maintenance, said bar-shaped housing can adopt between connector shell by the electric machine casing at the vibration head housing of front end, middle part and tail end and interconnect threadably successively.
Because what the drive motors in the motor built in type immersible concrete vibrator of the utility model said structure adopted is permanent magnet DC motor, the required dc source of its work only needs can make civil power 50Hz single phase poaer supply realize conversion by a simple bridge rectifier.This volume is little, and the mode of lightweight rectifier most convenient is arranged at it within vibrator exactly.Therefore, advantage such as its noise that not only possesses existing like product equally and had is little, and cancelled present like product essential and variable-frequency power sources equipment bulky complex again, further simplify the structure, be more convenient for using, also made things convenient for the manufacturing simultaneously, reduced cost.By adopting the Nd-Fe-B rare-earth permanent magnet direct current generator, can also reach and can improve rotating speed, promptly improve vibration frequency, increase the purpose of oscillation power, volume is greatly reduced, and little and little characteristics and the requirement in space of the vibrator diameter that is content with very little is convenient to install.
Below foregoing of the present utility model is described further with example shown in the drawings.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.
Fig. 1 is the structural representation of the above-mentioned vibrator of the utility model.
Front end in the utility model motor built in type immersible concrete vibrator as shown in the figure, its bar-shaped housing is a vibration head 2, is provided with the rotating eccentricity piece 3 through bearing 1 and bearing 5 supportings in its vibration head housing 4.Be provided with the permanent magnet DC motor that is made of Nd-Fe-B permanent magnet 8, brush carrier 10 and armature 7 in the electric machine casing 9 at middle part, its armature 7 supports and is arranged in the housing 9 through bearing 6 and bearing 11, and directly is connected with rotating eccentricity piece 3.Permanent magnet 8 in the permanent magnet DC motor is respectively by watt N that the shape Nd-Fe-B permanent magnet is formed of several piece same polarity, the permanent magnet of a pair of utmost point of S.Armature 7 required electric currents provide via brush carrier 10, and the connector 12 of its lead-in wire by being positioned at tail end and conduit 13 and the bridge rectifier that is arranged at the appropriate format of electric wire connecting junction 14 are connected with the single phase poaer supply of outside 50Hz.The bar-shaped housing of vibrator then is to interconnect with screw thread successively by the connector shell of the electric machine casing 9 at the vibration head housing 4 of front end, middle part and tail end is same.After connecting with the civil power of outside, be converted to direct current, can drive rotating eccentricity piece 3 by the permanent magnet DC motor in the vibrator and produce vibration by the bridge rectifiers in the electric wire connecting junction 14, concrete vibrating is closely knit.
