Abstract

The utility model provides a vibrator for concrete construction. The vibrator is additionally provided with a power frequency converter, a miniature motor is directly installed in a casing of a vibrating rod, and simultaneously, an eccentric block which has small eccentricity and large eccentric quality is fixed on an output shaft of the motor. In addition, the shaft section of the casing of the vibrating rod is made into a regular polygon shape or a regular polygonal shape. The vibrator has the advantages of simple structure, small transmission loss, low energy consumption, high vibration frequency, large vibration amplitude, improved concrete compactness, low noise and no vibration damage to operators.

Description

A kind of special type concrete vibrator

The utility model relates to vibrator used in a kind of building operations.

At present, the motor of conventional vibrator separates with its vibrating head.The power of motor is to be input in the vibrating head by Bowden cable.Its high vibration frequency be by the oscillator in the vibrating head in the motion of rotation and revolution, and bump between the raceway in the vibrating head, rubbing obtains.Therefore this conventional vibrator noise is big, and environment is wrecked, and its power transmission loss is big simultaneously, needs motor power (output) bigger.And when using, the operator is holding the gum sleeve of the flexible axle outside that runs up, and makes operator's sense of shaking strong, suffers from the vibration occupational disease easily.93 years inventors have invented " a kind of new concrete vibrator " (ZL93239452.3) once at the weak point of existing vibrator.This novel vibrating device is that motor is placed in the housing of vibrating head, does not have the transmission Bowden cable, so its noise is little, and energy consumption is low, and the operator is not had the sense of shaking by force.The geometry of its eccentric block has determined that eccentric mass is too little.The profile face of cylinder of vibrating head determines that again its amplitude is little.Thereby this vibrator can't improve concrete compactness greatly.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provide a kind of not only power transmission loss little, energy consumption is low, and is simple in structure, easy to operate, noise-less pollution, the operator is not produced the sense of shaking by force, and vibration frequency is higher, amplitude is bigger, exciting force is stronger, can improve the concrete vibrator of concrete density greatly.

The purpose of this utility model is to arrive by following measure: this vibrator is that micromachine is directly placed in the housing of vibrating head.And it is little on the output shaft of motor eccentric throw to be housed, the eccentric block that eccentric mass is big.Simultaneously between the input cable of this vibrator and output cable, be connected in series a power converter.The vibrating head of this vibrator is formed by connecting by front portion, middle part and afterbody in addition.

Eccentric block in the utility model, its axial section can be fan-shaped, and central angle is 40 °～90 °.The axial section of eccentric block can also be for arc, and its central angle is 90 °～140 °.

The enclosure axis section of the vibrating head front portion in the utility model can be regular polygon, also can be just many prismatics, can also be rounded.The axial section of the axial section of middle housing and afterbody shell also is both can be regular polygon, also can be just many prismatics, also can be rounded.

The drawing of accompanying drawing is described as follows:

The utility model is described in further detail below in conjunction with embodiment: this vibrator is that vibrating head (5), micromachine (6), eccentric block (7), sebific duct (4), input cable (1), output cable (3) and power converter (2) are formed.Wherein vibrating head (5) is assembled successively by anterior (5-1), middle part (5-2) and afterbody (5-3), and the axial section of the shell of anterior (5-1), middle part (5-2) and afterbody (5-3) all is regular polygon.Micromachine (6) is directly installed in the housing of vibrating head (5).Axial section is fan-shaped eccentric block (7) and is positioned at vibrating head (5) housing, and is fixed on the output shaft of micromachine (6), as the exciting piece.Input cable (1) one end and plug join, and the input of the other end and power converter (2) joins.And the output of output cable (3) one ends and power converter (2) joins, and after allowing it pass through sebific duct (4), directly enters in the vibrating head (5), joins with micromachine (6).The combination collocation of the shell section configuration of the front portion (5-1) of whole elsewhere vibrating head (5), middle part (5-2), afterbody (5-3) can be varied.Can be anterior (5-1), middle part (5-2), afterbody (5-3) all for just polygon, also can be that anterior (5-1) and middle part (5-2) is regular polygon, afterbody (5-3) is a circle.Equally, the combination collocation of above four kinds of forms is arranged also when the shell section configuration of front portion (5-1), middle part (5-2) and afterbody (5-3) during for many prismatics just.

When this vibrator uses, earlier attaching plug is inserted in the electrical socket, the civil power of 50Hz is directly inputted on the motor through bringing up to more than 10000 times/minute after the power converter frequency conversion, motor is reached run up.Drive eccentric block then and also begin to run up, produce frequency height, exciting force that amplitude is big along with the rotation of eccentric block, thus the concrete puddling is real.

The utility model is compared calamity has technology to have following advantage: this vibrator structure is simple, and driving-chain is few, machine Tool usefulness height, obvious energy conservation. Vibration frequency height, amplitude are big, can greatly improve concrete packing. Every Have the soil of single-phase 220V power supply to use, so it is easy to use, scope is wide. And its operation both Simply again laborsaving, all little than existing vibrator to operator's noise and hazard of vibration.
