Description

A kind of vibrator

The utility model is relevant with anti-material of indefinite form or Concrete Construction, relates to a kind of auxiliary equipment that anti-material or concrete pouring are used that is used for.

The electronic vibrator of plug-in type is adopted in domestic unsetting anti-material or the concrete cast that is used for industrial furnace at present usually.Because the space between template and the member is less, and the centre all has anchor studs or reinforcing bar etc. usually, and the effect of therefore vibrating is often very poor, and owing to there is the dead angle, and the defective of pore, cavity, pitted skin often appears in the casting quality instability.

The purpose of this utility model is, overcomes the deficiencies in the prior art, and a kind of vibrator that anti-material cast can be used for concrete pouring again that promptly can be used for is provided;

Providing a kind of is the pneumatic vibrator of power with compressed air.This vibrator can directly connect as a whole with cast template, drive template and vibrate together, need not special messenger's operation, can significantly improve the casting quality and the precision of unsetting anti-material, alleviate working strength of workers greatly, compare with the electronic vibrator of employing plug-in type and can improve work efficiency 3-4 doubly.

To achieve these goals, the utility model has adopted following technical scheme; A kind of vibrator is a power with compressed air; Mainly form by the end cap and the key combination that are fixed on cylinder shell, central axis, blade, the vibration cover on the base and are arranged at the housing two ends; The central axis that is set with vibration cover on it passes the housing with its coaxial line, is fixed on the end cap that is arranged at the housing two ends by the key that is arranged in its two ends keyway; One end of described central axis is an air inlet, other end sealing; Central axis is provided with radially gas booking groove of an axial groove that is connected with described air inlet and several; Described blade is arranged in the axial groove of central axis; Be symmetrically arranged with several steam vents on the two end cap; When the upper end that inner surface is overlapped in the upper end and the vibration of described central axis external surface was tangent, the lower end circular arc of two end cap upper air-vent was tangent with the inner surface that vibration is overlapped, and air inlet and steam vent disconnect; When the lower end that inner surface is overlapped in the lower end and the vibration of described central axis external surface is tangent, air inlet and steam vent conducting; Described base can be flat, also can be circular arc type.

Compared with prior art, the utlity model has following advantage:

1, because its base can be designed to various forms, can be directly with cast template or connected as a whole by pour mass and drive template and vibrate, need not special messenger's operation, can alleviate working strength of workers greatly.

2, pass through to change the relative angle of blade and steam vent and base, the vibration that can produce required any direction, and can realize comprehensive work, and stopped the vibration dead angle, can significantly improve unsetting anti-material or concrete casting quality; With adopt the electronic vibrator of plug-in type to compare can to improve work efficiency 3-4 doubly.

3, because the utility model is power with compressed air, aeroperformance is good, the mechanical efficiency height, be specially adapted to unsetting anti-material or concrete casting and constructing, also can be used as the instrument that vibrates in other place and the vibration source of plant equipment, can generally replace electric vibrating machinery, safe and reliable, long service life.

4, the utility model is simple in structure, and volume is little, low cost of manufacture.

5, the utility model is simple to operate, installation, convenient disassembly, and compliance is strong, can be widely used in industry, civilian construction industry.

Below in conjunction with drawings and Examples the utility model is described in further detail.

A kind of vibrator as shown in Figure 1 is a power with compressed air; Mainly combine by the end cap 1 and the key 7 that are fixed on cylinder shell 3, central axis 5, blade 4, the vibration cover 2 on the base 6 and are arranged at the housing two ends; The central axis 5 that is set with vibration cover 2 on it passes the housing 3 with its coaxial line, is fixed on the end cap 1 that is arranged at housing 3 two ends by the keys 7 that are arranged in its two ends keyway 8.As Fig. 4, shown in Figure 5, an end of described central axis is an air inlet 10, other end sealing; On central axis, be provided with radially gas booking groove 12 of an axial groove that is connected with described air inlet 10 11 and several; Described blade 4 is arranged in the axial groove 11 of central axis 5; Be symmetrically arranged with several steam vents 9 on the described two end cap 1.As shown in Figure 2, when the upper end and the upper end of vibration cover 2 inner surfaces of described central axis 5 external surfaces were tangent, the lower end circular arc of the steam vent 9 on the two end cap 1 was tangent with the inner surface of vibration cover 2, and air inlet 10 disconnects with steam vent 9; As shown in Figure 3, when the lower end and the lower end of vibration cover 2 inner surfaces of described central axis 5 external surfaces are tangent, air inlet 10 and steam vent 9 conductings; Various ways such as that described base 6 can be designed to is flat, circular arc type.

Vibrator as shown in Figure 1 forms working chamber by the inner surface that vibrates cover 2 with the inner face of end cap 1, the external surface and the blade 4 of hollow shaft 5.As Fig. 2, shown in Figure 3, compressed air is entered by air inlet 10 in the axial groove 11 of hollow shaft 5, by be arranged on the hollow shaft 55 radially gas booking groove enter into working chamber; Because this moment, working chamber was an enclosure space, constantly entered along with compressed-air actuated, the pressure in the working chamber constantly raises, and blade 4 will outwards move, and promotes 2 motions of vibration cover; Along with the motion of vibration cover 2, working chamber will be connected with 3 steam vents 9 of end cap 1, and the pressure in the working chamber descends rapidly.After vibration cover 2 moved to the limit, because the lower end of vibration cover 2 inner surfaces and the lower end of hollow shaft 5 external surfaces are close together, blade 4 was close to the upper end of vibration cover 2 inner surfaces, makes working chamber be isolated into two parts.A part is in communication with the outside air inlet 10 by the steam vent 9 of end cap 1; Another part only is communicated with the air inlet 10 of hollow shaft 5, and vibrator reaches duty as shown in Figure 3.After compressed air continues to enter into this part working chamber, along with the continuous rising of pressure, make vibration cover 2 motion round about, the volume of this part working chamber increases gradually and is separated with hollow shaft 5 gradually, be connected with another part working chamber, the interior pressure of working chamber this moment descends rapidly.When the air effect power on the blade 4 was overlapped 2 active force less than vibration, blade 4 was return in the axial groove of hollow shaft 5, and vibrator returns to duty as shown in Figure 2.Repeat above-mentioned action, can produce continuous vibration.
