Abstract

The attached vibrator consists of motor and speed increasing mechanism, and has one first large gear on the outer end of the motor shaft meshed to the first small gear on the middle shaft, one second large gear on the middle shaft meshed to the second small gear on the high speed shaft, and eccentric block fixed to the outer end of the high speed shaft. Compared with the existing high-frequency attached vibrator, the high-frequency attached vibrator has the advantages of low manufacturing cost, high vibration frequency, large vibration force, small amplitude and high compactness of concrete members.

Description

Form vibrator

The utility model relates to a kind of form vibrator, the usefulness of jolt ramming when mainly supplying large-sized concrete (concrete) element precast.

The medium-and-large-sized concrete member of present domestic science of bridge building prefabricated uses common form vibrator as T type beam etc.Vibration frequency low (50HZ).Amplitude big (2.8MM), the moment energy is most of during vibration consumes in the deformation of steel form, is delivered to concrete mixed material excited vibration little energy, inefficiency, consumption is big, the cost height.And another is the high frequency form vibrator of the generator frequency conversion unit power supply of particular power source 150HZ, though it has remedied the shortcoming of common form vibrator, but it is too high that the shortcoming of itself maximum is exactly a cost, the volume heaviness, the price of every cover is 30 times of common form vibrator price approximately, to the user can't be accepted, be exactly to accept reluctantly, give country's waste a large amount of funds undoubtedly.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art and the form vibrator that performance is good and price is lower is provided.

The purpose of this utility model can reach by following measure:

The utility model is made up of motor and speed increasing mechanism, is loaded on the one-level pinion on the one-level gear wheel engagement jackshaft of motor shaft outer end, the secondary pinion on the secondary gear wheel engagement high speed shaft on the jackshaft, and the high speed shaft outer end is fixedly connected with eccentric block.

The motor cabinet two ends are fixedly connected with bearing block and gearbox, and jackshaft is loaded on bearing block and the gearbox by rolling bearing.

High speed shaft is loaded on motor shaft and the gearbox by rolling bearing, and gearbox and eccentric block are set with cover outward.

Accompanying drawing 1 is always schemed for broken section of the present utility model.

The accompanying drawing piece number is represented:

1, motor 2, motor shaft 3, bearing block 4, jackshaft

5, rolling bearing 6, one-level pinion 7, one-level gear wheel 8, secondary gear wheel

9, gearbox 10, secondary pinion 11, eccentric block 12, motor cabinet

13, cover

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Fig. 1 represents structure of the present utility model, mainly is made up of motor 1 and speed increasing mechanism, and motor is that prior art two go out shaft type.At motor shaft 2 two ends bearing block 3 is housed, jackshaft 4 is housed on the bearing block 3, rolling bearing 5 is arranged outside jackshaft the inner, be set with one-level pinion 6 and secondary gear wheel 8 on the jackshaft.One-level gear wheel 7 engagement and the transmission one-level pinions of motor shaft outermost end are to obtain the one-level speedup.Outside the bearing block 3 gearbox 9 is housed, the outer end of jackshaft is loaded on the gearbox 9 by rolling bearing 5.Be set with secondary pinion 10 on the high speed shaft 10 at gearbox center, secondary pinion and 8 engagements of secondary gear wheel are to obtain the secondary speedup.High speed shaft the inner is loaded on the motor shaft by rolling bearing, and the high speed shaft outer end is loaded on the gearbox by rolling bearing, and the high speed shaft outer end is fixedly connected with eccentric block 11.Gearbox and eccentric block are equipped with cover 13 outward.

During use, the present embodiment motor rotational shaft speed is 2870 rev/mins, through the one-level speedup, and 5087 rev/mins of jackshaft turn ups, through the secondary speedup, 9000 rev/mins of high speed shaft turn ups.Flat heart piece obtains vibration at high speed under high speed shaft drives, motor cabinet is fixedly connected with the plate (expression on the figure) that places on the prefabricated concrete for 12 times, by this plate with the jolt ramming concrete.

The existing technology of the utility model contrast has following advantage:

Cost than existing high-frequency attached vibrator is much lower; Than present common form vibrator vibration The frequency height; Vibration force is big; Amplitude is little; Concrete member packing height.
