Abstract

The utility model relates to a built-in multi-motor concrete tampering vibrator which uses two or more than three AC or DC motors, or medium frequency motors, and the motors are connected in series up and down, and fixed in a stick body. An eccentric vibration generator or a planetary motion vibration generator is directly driven to work without a flexible shaft, so that the vibration of high power is obtained. The utility model provides building construction with a simple and practical concrete tampering device which has the functions of energy saving, low noise and high vibration.

Description

Built-in type multiple-motor concrete tamping vibrator

The utility model belongs to the building machinery category, is a kind of electrodynamic type vibrator.For building operations provides a kind of easy, practical, energy-conservation, low noise, high efficiency stamped concrete equipment.

Existing electric vibrator, generally be divided into large, medium and small three kinds of forms: the large-scale vibrating device of vibrating head diameter more than 80 millimeters, go into formula for the direct connection skewer, because of the vibrating head size bigger, enough spaces are arranged, motor directly can be contained in the vibrator head, directly drive off-centred dipole work, need not through the flexible axle transmission; Diameter medium and small vibrator, its head space size below 70 millimeters is less, select for use the sized motor that satisfies the vibration performance requirement to have any problem, especially the miniature electric acc power is little, do not reach the vibration index, so all be that motor is contained in the outside for many years, the form of structure of centre off-centred dipole in flexible axle drives vibrating head is called for short cable type.

The cable type electric vibrator, relative weight is big, complex structure, operator's both hands are held the central siphon by the high speed rotary flexible shaft, will follow together during work and be shaken, and are easy to fatigue, draw occupational disease, and one also needs two people to handle sometimes; Particularly the flexible axle transmission can not reverse, and bent intermediate is serious wear partly, and often twists off, and needs to shut down to change, and mistakes and delays work; The motor energy can not transmit fully, and loss is more.

The purpose of this utility model provides that a kind of profile is little, and power is big, and is easy and simple to handle, do not have and follow the sense of shaking, without flexible axle, motor directly drives off-centred dipole or planetary motion oscillator, thereby cuts down the consumption of energy, reduces the stamped concrete vibrator of noise, raising utilization rate.

The purpose of this utility model is achieved in that in order to install motor in the medium and small vibrating head below 70 millimeters at diameter at first must possess enough power and rotating speed.Select two or three above interchanges or dc motor or intermediate frequency motor, the upper and lower ticker both sides that uprightly are installed in for use, directly give a plurality of motor power supplies from power supply grid or converter power supply with lead, drive off-centred dipole or the work of planetary motion oscillator simultaneously by a plurality of motor, just can satisfy the requirement of small-volume large-power, high rotating speed strong vibration, need not the flexible axle transmission, thereby reach the purpose of this utility model.

Operating principle of the present utility model, the following example of form of structure and accompanying drawing thereof illustrate.

Figure one. and adopt two interchanges or dc motor to drive the vibrator schematic diagram of oscillator work

The multiple-motor vibrator partly is made up of vibrating head, supply line two as can be seen from figure one: the power switch (1) of energy waterproof is equipped with in one of supply line, be connected with attaching plug (3) by plastic wire (2), the other end is connected with vibrating head for the rubber hose (4) of band iron wire sheath, and the flexible pipe inner lead directly is connected with respective motor; Vibrating head is made up of excellent root (5) barred body (6) caput (7) etc., upper and lower uprightly being fixed in the housing of two or more interchanges or dc motor or intermediate frequency motor (8) [this example adopts two the dual-purpose series excitation formula of AC and DC motor], motor directly drives mass eccentricity oscillator or planetary motion oscillator (9) work.The ticker position can be adjusted by the vibration shape is different, and shown in the illustration, motor mounting is on the upper and lower both sides of ticker.

Select for use micromotor to make many motor oscillatings device, motor (8) directly is contained in the barred body (6), installs insulating layer (10) additional between motor (8) and the barred body (6), leakproof when guaranteeing work.

When many vibration generators were operated: at first attaching plug is inserted on the socket securely, connects switch then, each motor promptly drove off-centred dipole or planetary motion oscillator (9) rotation at a high speed, because the out-of-balance force effect makes vibrating head produce dither.Vibrator insert is mixed in the concrete that mixes, through this dither, smash concrete with consolidation be consolidated.

Claims

1. many motor oscillatings of stamped concrete device is characterized in that the interchange more than two or three, direct current or intermediate frequency motor (8) are directly installed in the barred body (6) of vibrating head.

2. according to right 1 described vibrator, it is characterized in that the upper and lower upright series connection of each motor directly drives off-centred dipole or planetary motion oscillator (9) rotates.

3. according to the described vibrator of right (1), it is characterized in that increasing between motor and the barred body (6) dielectric isolation layer (10).
