Description
[technical field]
The present invention relates to a kind of building implement, refer to a kind of portable safe electric control vibrating bar especially.
[background technology]
At present, the tradition vibrating head that is used for the concrete tamping generally has following two kinds of forms:
First kind is the vibrating head of split-type structural, in vibrating head peripheral hardware common asynchronous moter, motor connects transmission with flexible axle, and flexible axle drives off-centred dipole and forms vibration, owing to adopt the flexible axle transmission, efficient is low, be tending towards more obvious along with the increase of flexible axle length, therefore, power of motor is bigger, the energy consumption height causes the energy excess waste.
Second kind is the vibrating head of monolithic construction, common asynchronous moter or non-brush permanent-magnet DC motor are directly embedded barred body, directly drive off-centred dipole by the rotor of motor and form vibration, the operating voltage of this motor is 220V, even higher, makes progress on the structure, but because operating voltage is 220V, even higher, electric leakage easily, harm people's life.The patent No. is that 02210407.0 " a kind of new concrete vibrator " utility model patent and the patent No. are " backpack dither rod machine " utility model patent of ZL 200820018497.X, provide 42V safety power supply with generating set for vibrating head, improve safety, but the generating set heaviness is carried trouble, working strength is big, and generator is longer to line between the vibrating head, because electric current is big, line pressure falls just big, the line loss consumption is big, and efficient is low.
At second kind of vibrating head, the novel vibrating rod has been done some improvement, and vibrating head barred body and variable-frequency power sources are done together.The patent No. is ZL's 200520018353 " the integrated concrete vibration bar of brshless DC motor " utility model patent, in the 3rd page of the 8th row record of its manual " because in brushless direct current motor controller; lead links to each other by rubber hose barred body motor ", though barred body can be taken apart mutually with the controller part, lower percent defective in the use, but because the middle rubber hose of using links to each other, thereby, the heat radiation of controller can only be by the heat radiation of controller part shell, and flexible pipe will be arrested barred body earlier when operation, takes controller behind the aligned position again, use inconvenience, simultaneously, though some adopts the electric leakage power switch, import power supply and motor side power sourced electric and do not realize isolating fully, in case the situation of operating personnel's life security then can appear endangering in detection of electrical leakage disabler in the electric leakage power switch.Application number is " concrete vibration bar " patent of invention of 02111133.2, pass through tubular compliant conductive glued membrane between barred body and the controller, though handled easily, owing to barred body can not be taken apart mutually with the controller part, the vibrating head barred body is bad easily, even disconnected, if barred body has been broken, the controller of vibrating head also needs to change, thereby percent defective is very high in the use.Application number is " concrete vibration bar " patent of invention of 200510021917.0, and these pluses and minuses and application number are that 02111133.2 patent is identical.Application number is 03103067.X's " energy-saving hand-held concrete vibrator " patent of invention, also is by long cable between its controller and the motor, and corresponding shortcoming is identical with patent No. ZL 200520018353 patents.
