Abstract
The utility model discloses an immersion concrete vibrator with a built-in motor, belonging to a vibrating-densifying machine used in pouring constructions, and is characterized in that the utility model changes the structure that a rolling conical roller path supported by a cantilever in an existing vibrating rod does irregular constrained rotations to generate vibrations, but adopts the structure that the motor is directly coupled with an eccentric shaft with double supporting points to generate forced exciting force with high speed and high frequency. Therefore, the vibrating rod can not bring about automatic vibration stopping phenomena either in starting up or in work process, which improves the stress situation of rotary pieces in the vibrating rod, enhances the productivity and the service life of the vibrating rod, and reduces noise to below 70dB (A).
Description
The utility model belongs to vibration compacting machinery used in the pouring concrete construction, is applicable to the dense concrete work in the engineerings such as building, railway, bridge, hydraulic engineering, port and pier.
Known this type of concrete vibrator normally is made up of power source (motor or motor), flexible axle assembly and vibrating head.In vibrating head, tapper is made rolling movement along raceway, causes the centrifugal action of mass unbalance, to obtain dither.The deficiency that this vibrator exists is difficulty (motor start then need manually knock assist starting of oscillation), unlubricated (then depressed if any oil, water in the rod), quick abrasion, a fault rate height of starting of oscillation; Dark when breaking concrete easily by reinforcing bar or closely knit after concrete clamp, cause failure of oscillation, and the vibrating head after clamping is difficult for taking-up; Noise height after it starts in addition, giving does not disturb residents in the construction at a high speed brings insoluble problem.
The purpose of this utility model provides a kind of efficient, long-lived, low noise and has strong exciting force, safe and reliable novel vibrating device.
The utility model is realized by following technique measures:
A kind of concrete vibrator of being made up of power source (high frequency low voltage generating set), flexible pipe, lead, vibrating head is characterized in that vibrating head directly drives eccentric shaft and forms by being loaded on motor in the barred body, and its operating principle is as follows:
When generating set sends the high frequency low-voltage by lead, make built-in motor get electric rotation, during rotor rotation, connect eccentric shaft by steel ball and rotate, produce the exciting force with the motor synchronous frequency, and produce amplitude and the vibration compacting concrete by barred body.
The utility model has the advantages that: do irregular constraint with the tapper of cantilever support along tapered raceway in the change past vibrating head and rotate vibrative structure, and the structure that adopts motor directly to connect with two fulcrum eccentric shafts, thereby produce mandatory high-speed high frequency exciting force, make no matter vibrating head is in the start or the course of work failure of oscillation phenomenon voluntarily not to take place all, improved the stressing conditions of revolving part in the vibrating head simultaneously greatly.And noise is reduced to 70dB(A) below, national standard is 85dB(A) ］, other performance reaches the GB8529-87 standard.
Below by embodiment and accompanying drawing the utility model is described in further detail, accompanying drawing is depicted as the utility model concrete vibration bar schematic diagram.
A kind of concrete vibrator, form by power source (high frequency low voltage generating set), flexible pipe, lead and vibrating head, it is characterized in that vibrating head is by shaking point 1, barred body 2, hose coupling 14, flexible pipe 15 and be installed in bearing support 13, lining 8, bearing 3,6,12 in the barred body 2, be loaded on eccentric shaft 5 and built-in rotor 11 on the bearing 3,6,12, the built-in motor stator 9 that is loaded in the lining 8 is formed, wherein eccentric shaft 5 and rotor 11 connect by hexagon socket head cap screw 4, and the moment of torsion between them transmits by steel ball 7.
The utility model mainly is the improvement to ZN50 type vibrating head in the existing vibrating head specification, so its barred body is by 50 type specification manufacturings.
Claims (2)
1, a kind of concrete vibrator, by power source (high frequency low voltage generating set), flexible pipe, lead and vibrating head are formed, it is characterized in that vibrating head is by shaking point 1, barred body 2, hose coupling 14, flexible pipe 15 and be installed in bearing support 13, lining 8, bearing 3,6,12 in the barred body 2, be loaded on eccentric shaft 5 and built-in rotor 11 on the bearing 3,6,12, the built-in motor stator 9 that is loaded in the lining 8 is formed, wherein eccentric shaft 5 and rotor 11 connect by hexagon socket head cap screw 4, and the moment of torsion between them transmits by steel ball 7.
