Abstract
The utility model relates to a noise-free type concrete vibrating rod, mainly comprising a vibrating rod body (4). One end of the rod body (4) is connected with a working head (1), and the other end is connected with a frequency increase device (5) and a hose connection head (6). The utility model is characterized in that the inner of the wall of the rod body (4) the inner of the wall of the working head (1) are aggregately provided with three fixing bearings (2), both ends of a centrifugal shaft (3) are fixed to the bearings (2), and the right end is connected with a flexible shaft by the frequency increase device (5), a bearing (8) and a flexible shaft connection head (7). When the utility model works, it has no noise, and it has high intensity of vibration and long service life.
Description
Technical field
The utility model relates to a kind of building machinery, and a kind of noiselessness vibrating head of concrete vibrator particularly is provided.
Background technology
Existing vibrator mainly is made up of motor, flexible axle flexible pipe and vibrating head three parts.Mainly contain two kinds, a kind of tapper raceway that is suspended wall supports is made irregular constraint vibration and is produced vibration, because tapper pounding on raceway produces very big noise.Another kind is the low-noise vibrating rod that utilizes eccentric structure to make, and its noise is reduced, but oscillation intensity is little, and power and operating frequency do not reach instructions for use.
Summary of the invention
Produce noise effect environment and the low shortcoming of vibration frequency in order to overcome existing vibrating head, the utility model provides the concrete vibration bar of a kind of simple in structure, noiselessness, long service life.
The technical solution of the utility model is: main involving vibrations rod barred body, end at its barred body connects working head, the other end connects frequency raiser and hose coupling, it is characterized in that in the barred body wall He in the working head wall, being provided with three rigid bearings altogether, the centrifugal shaft two ends are fixed on the bearing, right-hand member is connected with flexible axle by frequency raiser, bearing, flexible shaft end, and flexible shaft end, be need not any attachment device and just can reach the noiseless requirement of high frequency efficient in hose coupling by bearing fixing.
The utility model is because the centrifugal shaft two ends connect stress balance, the effect of frequency raiser in addition with bearing fixing, power significantly improves, and makes oscillation intensity improve 3 times, simultaneously, the centrifugal shaft rotation produces vibration during work, does not have and beats the barred body phenomenon, does not have any noise, its intensity reaches the technical standard of concrete vibrator fully, need not any maintaining in the use, long service life has been improved the noisy environment of operator and construction working greatly, reach environmental requirement, continuous construction is had no effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among Fig. 1, working head 1, rigid bearing 2, centrifugal shaft 3, barred body 4, frequency raiser 5, hose coupling 6, flexible shaft end 7, bearing 8.
The specific embodiment
The vibrating head of the concrete vibrator among Fig. 1, main involving vibrations rod barred body 4, one end of barred body 4 is connected with working head 1, the other end connects frequency raiser 5 and hose coupling 6, two has three rigid bearings 2 in barred body 4 walls and in working head 1 wall, centrifugal shaft 3 two ends are fixed on the bearing 2, and flexible shaft end 7 is fixed in the hose coupling 6 by bearing 8.Working head 1 and hose coupling 6 are connected with barred body 4, all adopt static seal to connect, in case muddy water is invaded.The utility model can be connected use with existing various model vibrators.
Claims (2)
1, a kind of noiselessness concrete vibration bar, main involving vibrations rod barred body (4), end at its barred body (4) is connected with working head (1), the other end is connected with frequency raiser (5), hose coupling (6), it is characterized in that: be provided with three rigid bearings (2) altogether in barred body (4) wall and in working head (1) wall, centrifugal shaft (3) two ends are fixed on the bearing (2), and right-hand member is connected with flexible axle through frequency raiser (5), bearing (8), flexible shaft end (7).
2, a kind of noiselessness concrete vibration bar according to claim 1 is characterized in that: centrifugal shaft (3) right-hand member connects frequency raiser (5), makes it improve 3 times vibration frequency.
