Abstract
The utility model relates to a noiseless concrete vibrating platform. The utility model is characterized in that board-shaped electromagnets are arranged on the full face of the upper side of a platform face, and a vibration generator is arranged under the platform face; the platform face is connected with a platform seat via a cylindrical or oblong vibration damper, and the platform seat is connected with a vibration amplitude adjustor via a cylindrical or oblong vibration damper; the vibration damper is sheathed in a corresponding vibration damping seat, and one end of the vibration amplitude adjustor is fixed on the platform seat by adjusting bolts. The vibration amplitude of the vibrating platform face can be adjusted by the vibrating platform, when the utility model vibrates, testing molds are sucked on the platform face; the vibration noise of the platform face and the testing molds and the impact noise generated at the time of idle vibration are eliminated; therefore, noiseless vibration is achieved, and the working environment of workers is improved.
Description
The utility model belongs to a kind of vibration moulding machinery, especially for the forming machine of concrete sample.
Available coagulation soil vibration platform is with the driven by motor eccentric block concrete die trial or mould on the table top to be vibrated, and realizes the closely knit moulding of concrete sample.When vibration, noise is very big, and the noise when its sky shakes surpasses 90 decibels, and die trial or mould and vibration table during vibration, reach more than 100 or 120 decibels noise without any fixing, and its noise makes operating personnel's health be subjected to infringement.Existing shake table mainly comprises table top, pedestal, vibrator, be connected with pretension bolt by spring between its table top and the pedestal, because the bolt behind the pretension is a fixed length, so when the upper and lower motion of table top, two end faces of bolt have just produced bump inevitably, thereby have caused high-frequency resonance.In addition, existing vibrator adopts articulated form, and its hinged place also can produce impact noise.
The purpose of this utility model is to provide a kind of noiselessness concrete vibrating stand, makes the noise index be lower than 70 decibels, and to the infringement of operating personnel's noiselessness, the noise when making concrete formation reaches the requirement of national defined.
Noiselessness concrete vibrating stand of the present utility model, mainly form by the connector between table top, vibrator, pedestal, table top and the pedestal, shock absorber, it is characterized in that: the top at table top is provided with tabular electromagnet comprehensively, between table top and pedestal, between pedestal and the amplitude modulator, be connected by cylindrical or rectangular shock absorber, shock absorber is inserted in the corresponding vibration proof mounting, and an end of amplitude modulator is bolted on the pedestal by adjustment.
When shake table is worked,, concrete die trial or mould are inhaled on table top owing in full court face scope, be provided with electromagnet; therefore eliminated the vibrating noise of die trial and table top; when stopping to vibrate, the suction of shake table is eliminated, and die trial can arbitrarily be taken off from table top.Adjust the compress degree of amplitude modulator with bolt, can adjust the amplitude of shake table,, improved the workman and be work situation because the reasonable setting of shock absorber and vibration proof mounting has been eliminated the impact noise when the shake table sky shakes, thereby reached the noiselessness vibration to table top.The utility model is applicable to various shake tables.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is the structural representation in the utility model cross section.
Fig. 2 is the structural representation in the utility model vertical section.
As shown in the figure: the utility model mainly is made up of connector and shock absorber between table top 2, vibrator 3, pedestal 4, table top and the pedestal, top at table top 2 is provided with rectangular plate shape electromagnet 1 comprehensively, between table top 2 and pedestal 4, between pedestal 4 and the amplitude modulator 5, be connected by cylindrical or rectangular shock absorber 6, shock absorber 6 is inserted in the corresponding vibration proof mounting 7, and an end of amplitude modulator 5 is fixed on the pedestal 4 by adjusting bolt 8.
