Description

A kind of new concrete vibrator

Affiliated technical field

This is novel to relate to a kind of safety, low noise is used for the closely knit vibrating spear of building operations industry cement concrete.

Background technology

In the construction of building building or structure, use vibrating spear to insert in the cement concrete and make it closely knit, to guarantee the engine request of building or structure.The internal vibration rod of present domestic use is driven Great Wall Software's axle and is rotated the operation of vibrating with ticker in the vibrating spear by common 380V/50Hz threephase asynchronous.During construction, the hand-held vibrating spear of operating personnel vibrates thereupon, human body is worked the mischief, and because high voltage, the time have personal injury to take place.The vibrating spear noise reaches the 80-90 decibel, and no matter the noise serious environment pollution particularly at municipal construction, is all surrounding environment to be worked the mischief on daytime or carry on construction work at night, and therefore influences the job execution progress.

Summary of the invention

The utility model purpose is to solve the uneasy congruent problem of aforesaid operations, and a kind of operating personnel are provided the hand-held new concrete vibrator that does not have the direct-type of shake sense, safety, low noise

This novel vibrator, it comprises vibrating spear, is connected and exports the power converter of 42V/200Hz safe voltage with vibrating spear; Described vibrating spear comprises and places 42V/200Hz high-speed electric expreess locomotive, temperature controller, eccentricity excitation axle that is made of stator and rotor in its housing and the vibration head that is threaded with vibrating spear end bearing bell and spigot joint; The 42V high speed rotor of motor adopts crossing spline directly to be connected with the eccentricity excitation axle, and the stator of its motor directly is fixed on the vibrating spear inner walls, and the rotor of motor is supported by bearing and bearing support, and the eccentricity excitation axle is by bearing and bearing holder (housing, cover) connection supports; Described temperature controller is serially connected on the high-speed electric expreess locomotive input line and is fixed on the end face of bearing support, and motor input line passes flexible rubber hose by electric machine joint and is connected with the power switch of frequency converter; Lubrication oil is housed in the vibrating spear, adopts the rubber seal sealing between high-speed electric expreess locomotive and the vibrating spear, adopt two rubber seal sealings between bearing holder (housing, cover) joint and the vibrating spear; Described vibration head is conical and replaceable, and its vibration head and bearing holder (housing, cover) joint oil filler point are sealed by the taper pipe thread plug.

This novel compared with prior art effect is as follows:

A, this vibrator are safe and reliable, noise is low, mainly be on the basis of former vibrating spear, to have additional the frequency converter that can offer high-speed electric expreess locomotive 42V safe voltage, it is coaxial and place vibrating spear with the eccentricity excitation axle to drive the stator of the high-speed electric expreess locomotive that vibrating spear rotates and rotor in addition, motor and frequency converter voltage coupling can prevent the motor electric leakage that human body is damaged like this; The logical input of high-speed electric expreess locomotive line passes flexible rubber hose and is connected with frequency converter, when operating personnel use, make the flexible rubber hose friction of handgrip part, there is not the sense of shaking yet, make it to guarantee more safety to human body, and make the construction noise value below 65 decibels, can satisfy the requirement of various varying environments and various concrete cement construction operations.

B, this vibrator are simple in structure, practicality is easily promoted, owing in the vibrating spear spindle oil is housed, when rotor and eccentricity excitation axle were rotated at a high speed, its mechanical loss was very little.Owing on motor shaft bearing end face temperature controller is housed, burnt out in the time of can preventing motor overheating or overload again, owing to adopt said structure, it is very big convenient to bring to installation and maintenance, therefore can easily promote.

Description of drawings

Fig. 1 is the overall structure figure that this novel vibrating spear is connected with frequency converter.

The specific embodiment

Referring to Fig. 1, this vibrator comprises vibrating spear 8, is connected with vibrating spear and exports the power converter 29 of specialized voltages 24V/200Hz for it; Described vibrating spear 8 comprises the high-speed electric expreess locomotive that is made of stator 13 and rotor 14 that places in its housing 17, temperature controller 18, eccentricity excitation axle 7 and the vibration head 1 that is threaded with vibrating spear 8 end axis bearing sleeves 4, its high-speed electric expreess locomotive is miniature individual event capacitor-operated motor, can mate with frequency converter 29 output voltages, described rotor 14 adopts cruciate flower directly to be connected with eccentricity excitation axle 7, the stator 13 of its motor directly is fixed on vibrating spear housing 17 inwalls, the rotor 14 of motor is by bearing 12,15 and bearing support 11,16 support, its eccentricity excitation axle 7 is by bearing 6, bearing holder (housing, cover) joint 4,9 support, and eccentricity excitation axle 7 can be selected trapezoidal eccentricity excitation axle or crank type eccentric shaft for use; Said vibration head 1 is conical and replaceable, and tightens up with two clamp-screws 3, prevents that vibration head 1 from coming off; Said bearing holder (housing, cover) joint 4 ends are provided with oil filler point, by this oil filler point is to be marked with lubrication oil in the vibrating spear 8, and rubber seal 5 is used by 2 sealings of taper pipe thread plug in this hole between described motor and the vibrating spear, 10 sealings seal with rubber double density seal 5 between bearing holder (housing, cover) joint 4 and the vibrating spear; Temperature controller 18 is serially connected on the motor power input line 22 and is fixed on the end face of bearing support 16, and motor input line 22 is connected with the power switch 23 of frequency converter through flexible rubber hose 21 by electric machine joint 19.When motor temperature was raised to 120 ℃, temperature controller 18 auto-cutouts can prevent that this motor from burning out.
