Description

Silencing vibrative hammer

Technical field

The utility model relates to a kind of constructional engineering machinery field, is specifically related to a kind of pile driver vibrating hammer, particularly a kind of silencing vibrative hammer.

Background technology

Vibrating hammer is claimed vibrohammer again, is widely used in the building piling on the building site.Vibrating hammer is when driving piles work; Vibrating hammer can produce high vibration; Carry out vibration damping so on vibrating hammer, be provided with damping device, the damping device on traditional vibrating hammer has generally included vibration-absorbing mounting, and vibration-absorbing mounting is installed on the gear-box of vibrator through spring assembly; Carry out vibration damping through spring, can produce bigger noise, noise surrounding environment in the spring damping process.

To the problem that above-mentioned vibration absorber exists, my company provides the improvement technical scheme at the disclosed low-noise vibrating hammer of the patent documentation of the patent No. 201120018475.5, changes traditional spring damping into rubber damping, greatly reduces vibrating noise; But still there is following defective: 1), also influenced effectiveness in vibration suppression to a certain extent though reduced noise because the effectiveness in vibration suppression of rubber does not have the good damping result of spring; 2) being used to settle the gear-box of the vibrator of vibration isolation rubber piece or spring is open setting; Not only foreign material such as external dust, stone particle are prone to get in shock-absorbing spring or the vibration isolation rubber; Influence the effectiveness in vibration suppression of shock absorber; And the open noise that is provided with down spreads easily, also strengthened external noise, severe contamination surrounding environment to a certain extent.

Summary of the invention

To the deficiency that prior art exists, the purpose of the utility model is to provide in a kind of course of work noise little, the silencing vibrative hammer of good damping result.

For realizing above-mentioned purpose, the utility model provides following technical scheme: a kind of silencing vibrative hammer, vibrator that include vibration absorber, is connected with vibration absorber and the clamping device that is connected with vibrator through Connection Block; Described vibration absorber includes vibration-absorbing mounting and spring damping mechanism, and the casing both sides gear-box of vibrator is provided with the mount pad that supplies said spring damping mechanism to install, and described spring damping mechanism includes spring shaft and is set in the spring base on the spring shaft; Spring shaft one end is connected with vibration-absorbing mounting; The other end is inserted in the mount pad, and said spring base is located at the mount pad top, and the spring base top is provided with the upper spring assembly; The below is provided with the lower spring assembly; Said upper spring assembly includes shock-absorbing spring and upper spring dish, and said lower spring assembly includes down shock-absorbing spring and lower spring dish, it is characterized in that: be provided with rubber washer between described upper spring dish and the last shock-absorbing spring; Be provided with down rubber washer between said lower spring dish and the following shock-absorbing spring; Pad is provided with rubber pad between following shock-absorbing spring and the spring base, is arranged with nylon washer on the described spring shaft, and spring socket sleeve is located on the nylon washer.

Technique scheme is all filled up between shock-absorbing spring and the spring base under reaching between upper and lower shock-absorbing spring and the upper and lower spring base and is established rubber, and spring contacts with rubber, greatly reduces rattle in the vibrating hammer course of work, reaches the purpose that reduces noise; Between spring base and the spring shaft nylon washer is set, nylon washer has avoided spring base directly to contact with spring shaft, has not only reduced noise, and has protected spring shaft to a certain extent.

The utility model further is set to: the mount pad outside on the casing both sides gear-box of described vibrator is provided with the sound insulating panel with the gear-box sealing.

Through adopting technique scheme; That sound insulating panel not only has is dustproof, the characteristics of anti-foreign material, and protection spring shock absorption mechanism works in clean environment, guarantees effectiveness in vibration suppression; And have soundproof effect, make vibrating hammer reach almost noiseless effect in the course of the work.

Below in conjunction with accompanying drawing the utility model is further described.
