Preferably, the driving element on the inner ring of the one-way bearing is a ball embedded in the inner circumferential surface of the one-way bearing, and can freely roll around the center of the ball; thereby minimizing frictional losses between the drive member and the helical steel strip.
The concrete vibrator that above-mentioned first technical scheme relates has: the hydraulic controller makes the sliding plug reciprocate along the axis of the base shell in the process of periodically pressurizing and decompressing the hydraulic cavity, namely, in the process of periodically filling and pumping oil into the hydraulic cavity, so that the spiral steel bar drives the inner ring of the one-way bearing to periodically rotate forwards and backwards; the inner ring of the one-way bearing drives the outer ring in forward rotation and is independent from the outer ring in reverse rotation, so that the spiral steel bar can drive the outer ring of the one-way bearing periodically and directionally in the reciprocating process, the rotating pipe is accelerated continuously and is increased to a higher level gradually, and the vibrator can generate a good vibrating effect; because no external mechanical driving mechanism is arranged, the vibrator has extremely low noise when working, does not influence the surrounding environment and has good energy-saving effect.
The second technical scheme adopted by the invention for solving the technical problems is as follows: the hydraulic concrete vibrator comprises a rod-shaped base shell; a hydraulic cavity is formed in the rear half section of the interior of the base shell, a sliding plug is arranged in the hydraulic cavity, an oil liquid area is arranged behind the sliding plug, and the oil liquid area is communicated to a hydraulic controller through a hydraulic pipe; the hydraulic controller periodically pressurizes and depressurizes the hydraulic cavity; the sliding plug is forwardly connected with a spiral steel bar extending along the axis of the base shell; a one-way bearing is sleeved outside the spiral steel bar, and a driving piece matched with the spiral steel bar is arranged on an inner ring of the one-way bearing so as to drive the inner ring of the one-way bearing to rotate when the spiral steel bar moves along the axial direction; the outer ring of the one-way bearing is fixed with the inner ring of an outer bearing sleeved on the periphery of the one-way bearing, and the outer ring of the outer bearing is fixed with the base shell, so that the outer ring of the one-way bearing can freely rotate; the outer ring of the one-way bearing is connected with a twist pipe which can synchronously rotate along with the outer ring of the one-way bearing, a twist-shaped circulating channel is formed in the twist pipe, and a counterweight ball which can freely move is arranged in the circulating channel.
Preferably, the driving element on the inner ring of the one-way bearing is a ball embedded in the inner circumferential surface of the one-way bearing, and can freely roll around the center of the ball; thereby minimizing frictional losses between the drive member and the helical steel strip.
Preferably, the weight ball is a shot ball.
The concrete vibrator that above-mentioned second kind technical scheme relates has: similar to the first solution, the twist tube is gradually accelerated to rotate; in the process of accelerating the twist pipe, the counterweight balls do reciprocating motion in the twist-shaped circulating channel; in the process, the center of gravity of the whole twist tube rotates around the axis continuously and does axial reciprocating motion, so that the whole rod-shaped base shell outputs circumferential and axial vibration simultaneously, the vibration mode is richer, and the vibration effect is further improved.

Fig. 2 is a schematic view of a second embodiment of the hydraulic concrete vibrator.
Detailed Description
The invention is further illustrated with reference to the following figures and examples:
the first embodiment is as follows:
in the first embodiment shown in fig. 1, the hydraulic concrete vibrator includes a rod-shaped base shell 1; a hydraulic cavity 10 is formed in the rear half section of the interior of the base shell 1, a sliding plug 2 is arranged in the hydraulic cavity 10, an oil liquid area is arranged behind the sliding plug 2, and the oil liquid area is communicated to a hydraulic controller (not shown) through a hydraulic pipe 101; the hydraulic controller periodically pressurizes and depressurizes the hydraulic cavity 10, namely periodically fills and pumps oil; the sliding plug 2 is connected with a spiral steel bar 3 extending along the axis of the base shell 1; a one-way bearing 4 is sleeved outside the spiral steel bar 3, and a driving piece 41 matched with the spiral steel bar 3 is arranged on the inner ring of the one-way bearing 4, so that the inner ring of the one-way bearing 4 is driven to rotate when the spiral steel bar 3 moves along the axial direction; the outer ring of the one-way bearing 4 is fixed with the inner ring of an outer bearing 5 sleeved on the periphery of the one-way bearing, and the outer ring of the outer bearing 5 is fixed with the base shell 1, so that the outer ring of the one-way bearing 4 can freely rotate; the outer ring of the one-way bearing 4 is connected with a rotating pipe 6 which can rotate synchronously with the outer ring of the one-way bearing 4, and one side of the rotating pipe 6 extends axially to form an eccentric balancing weight 61, so that the center of gravity of the rotating pipe 6 is positioned on one side of the rotating pipe.
In the hydraulic concrete vibrator, the driving member 41 on the inner ring of the one-way bearing 4 is a ball embedded in the inner circumferential surface of the one-way bearing 4, and can freely roll around the center of the ball; thereby minimizing frictional loss between the driving member 41 and the spiral steel rod 3. The front end of the rotary tube 6 is fitted in a front end bearing 60 at the front end of the base housing 1. The shape of the spiral steel strip 3 is the same as that of the spiral strip in the rotary mop.
In the vibrator, the hydraulic controller makes the sliding plug 2 reciprocate along the axis of the base shell 1 in the process of periodically pressurizing and decompressing the hydraulic cavity 10, so that the spiral steel strip 3 drives the inner ring of the one-way bearing 4 to periodically rotate forwards and backwards; because the inner ring of the one-way bearing 4 drives the outer ring in the forward rotation process and is independent from the outer ring in the reverse rotation process, the spiral steel bar 3 can drive the outer ring of the one-way bearing 4 periodically and directionally in the reciprocating motion process, so that the rotating pipe 6 is accelerated continuously and is gradually improved to a higher level, and the vibrator can generate a good vibrating effect; because no external mechanical driving mechanism is arranged, the vibrator has extremely low noise when working, does not influence the surrounding environment and has good energy-saving effect.
Example two:
for the second embodiment shown in fig. 2, it is different from the first embodiment in that the outer ring of the one-way bearing 4 is connected forward with a twist tube 7 which can rotate synchronously with the outer ring of the one-way bearing 4, a twist-shaped circulation channel is formed inside the twist tube 7, and a freely movable counterweight ball 71 is arranged in the circulation channel; the weight-balancing ball 71 is preferably a shot ball, having a relatively large weight.
In the second embodiment, the twist tube 7 is fixed in a tube 72, and the tube 72 is fixedly connected to the outer ring of the one-way bearing 4 and the inner ring of the front end bearing 60.
In the second embodiment, the twist tube 7 is gradually accelerated to rotate; during the acceleration process of the twist tube 7, the counterweight balls 71 do cyclic reciprocating motion in the twist-shaped circulating channel; in this process, the center of gravity of the entire twist tube 7 not only rotates continuously around the axis, but also reciprocates axially, so that the entire stick-like base shell 1 outputs circumferential and axial vibrations at the same time, and the vibration mode is made richer to further improve the vibrating effect.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, but rather as the subject matter of the invention is intended to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.
