Description
Technical field
The utility model relates to a kind of construction implement, relates in particular to a kind of vibratory concrete equipment.
Background technology
At present, the working forms of traditional concrete vibrator is to drive flexible axle by external motor to rotate, and hammer body is made circular motion around the barrel of tup in the driving caput, because tup can not be close to the barrel operation smoothly, promptly knock generation, and make caput under the effect of knocking of tup, produce vibration.People utilize the concrete compacting of this vibration realizing.This vibrator is a planetary type vibrator.Planetary type vibrator in use owing to be to knock to produce vibration, so produce very big noise, has a strong impact on the surrounding environment of job site, unfavorable environmental protection.And because the constraint of caput structure, when vertical use, the hammer body in the rod often produces linear movement, makes tup not knock barrel, and at this moment concrete is clamped caput easily, when lifting caput, sebific duct is damaged, and make the operator that the possibility of electric shock be arranged.
At present, the enterprise of the flexible axle planet immersible concrete vibrator that China produces generally is that medium carbon steel and mild steel form through heat treatment to the vital part and the selected material material of strength member of vibrator caput.Because the material of selecting for use is limit, and causes the internal toughness of component and the needs that case hardness does not all satisfy high vibration frequency and construction, reduce application life.
The utility model content
Technique effect of the present utility model can overcome above-mentioned defective, and a kind of concrete vibration bar is provided, and it improves vibration force greatly, effectively tamped concrete.
For achieving the above object, the utility model adopts following technical scheme: it comprises tip, exciting, sleeve pipe, and tip is arranged on the end of sleeve pipe, and tip is connected with the exciting in being arranged on sleeve pipe is sub; Exciting is connected with rotor by spring.
Tip at work with stone and the round-the-clock generation friction of sand, must there be enough hardness on its surface, the cone surface that is excited at the same time son forms planet point with the pointed cone surface again and swashs, producing height shakes frequently, therefore tip and exciting not only will have high rigidity, the active force of frequency owing to shake, core also must have enough toughness, past prolongs always uses the 40Cr material, do not satisfy instructions for use far away, so tip adopts the 20CrMnTi material, exciting employing 35CrMo material, technology and method by carbo-nitriding or gas carburizing are heat-treated, and case hardness can reach more than the 62HRC.Because change material, by modifier treatment, core can reach enough toughness.Sleeve pipe is connection tip and the part that supports exciting, and what prolonged usefulness in the past is the Q235A material always, because its external surface is direct and stone and sand generation friction, so application life is low.Now sleeve pipe is adopted the 45# seamless steel pipe, high-frequency quenching is carried out in modified rear surface, and hardness can reach 50HRC, thereby has improved application life.Spring is the strength member of caput assembly, and what the past prolonged usefulness always is the 65Mn spring steel wire, and fatigue resistance is low, by changing material, selects colod-application superior alloy steel spring steel wire 60Si for use
2Mn carries out rational heat treatment technology, thereby has improved the fatigue strength of spring.
Strength members such as the tip in the vibrating head caput assembly, sleeve pipe, exciting, spring are passed through to change material and Technology for Heating Processing, under the duty of high vibration frequency, improve the fatigue strength and the abrasion resistance of part, prolong the application life of vibrator to greatest extent, and part internal toughness and case hardness have been improved, to reach the purpose of improving the quality of products with reliability performance.
Be provided with bearing between the end of exciting one side that is connected with spring and the sleeve pipe.The end of rotor is provided with bearing, and bearing contacts with sleeve pipe by bearing support.
By changing the material of four strength members in the vibrator caput assembly, the case hardness of caput assembly and the fatigue strength of core toughness and spring are greatly improved, thus the application life of having improved flexible axle planet immersion vibrator.Reliability index than national construction industry industry standard JG/T 45-1999 regulation improves 13.5 times.
The utility model device prolongs application life greatly, and the vibrational structure compactness of vibrator can produce good economic benefit.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. tip; 2. sleeve pipe; 3. exciting; 4. bearing; 5. spring; 6. bearing support; 7. rotor.
The specific embodiment
Vibrator of the present utility model comprises tip 1, exciting 3, sleeve pipe 2, and tip 1 is arranged on the end of sleeve pipe 2, is connected with exciting 3 in being arranged on sleeve pipe 2; Exciting 3 is connected with rotor by spring 5.
Be provided with bearing 4 between the end of exciting 3 one sides that are connected with spring and the sleeve pipe 2.The end of rotor 7 is provided with bearing 4, and bearing 4 contacts with sleeve pipe 2 by bearing support 6.Tip 1 adopts the 20CrMnTi material, and exciting 3 adopts the 35CrMo material, and sleeve pipe 2 adopts the 45# seamless steel pipe, and spring 5 adopts 60Si
2The Mn material.
Component in the utility model, at first the material with tip 1 and exciting 3 is optimized, and reduces the content of carbon, increases Cr, Mo composition, to guarantee high tenacity, by rational heat treatment technology, improves the hardness and the abrasion resistance of piece surface.Next changes the material of sleeve pipe 2, improves the content of carbon, by rational heat treatment technology, reaches the purpose that improves case hardness.Spring 5 is one of strength members in the caput assembly, by changing material, selects colod-application superior alloy steel spring steel wire for use, increases the content of Si and Mn, by rational heat treatment technology, improves the fatigue resistance of spring.
Strength member in the R﹠D process is the core toughness of tip 1 and exciting 3 and the fatigue resistance of case hardness and spring 5.Tip 1 and exciting 3 must quench earlier, tempering, carry out semifinishing and finishing step again.Quenching hardness and the quenching of spring 5 and the key that fatigue strength is all manufacturing procedures before the grinding.
