Description

Vibration device for tube sheet pouring mold

Technical Field

The utility model belongs to subway section of jurisdiction makes the field, concretely relates to section of jurisdiction pouring die mould vibrating device.

Background

The existing subway segment manufacturing mould has an attached vibration mode and a fixed vibration motor vibration mode, and the two vibration modes respectively have advantages and disadvantages. The fixed vibrating motor shakes, and because of the exciting force of the vibrating motor is transmitted to the duct piece mould through the vibrating base upwards instead of directly acting on the mould, the concrete cannot achieve the ideal vibrating effect. The attached vibration mode is that the vibrator is attached to the bottom of the bottom plate of the duct piece mold, and the exciting force directly acts on the mold, so that the vibration effect on concrete is improved compared with the vibration mode of a fixed vibration motor.

However, the problem that bubbles exist on the side face of the duct piece cannot be well eliminated by any type of mould vibration mode, and the existence of the bubbles affects not only the appearance but also the quality of the duct piece.

Disclosure of Invention

An object of the utility model is to provide a section of jurisdiction pouring mold vibrating device effectively solves the section of jurisdiction and pours the discharge mode and the discharge quantity of in-process side bubble, and the section of jurisdiction side bubble quantity that significantly reduces the bubble diameter, improves section of jurisdiction outward appearance, improves section of jurisdiction quality.

In order to achieve the above object, the utility model provides a following technical scheme:

a vibrating device for a tube sheet pouring mold comprises a cam device and a vibrating mold connected above the cam device, and the vibrating mold is enabled to do seesaw motion by taking the cam device as a center.

Furthermore, the vibration die comprises a base, a plurality of stand columns are vertically arranged on the base, and die cavities are fixedly connected to the upper sides of the stand columns; the die cavity comprises an arc-shaped bottom plate, arc-shaped side baffles are arranged on two arc-shaped edges of the bottom plate, end baffles are arranged at two ends of each side baffle respectively, and the end baffles are connected to the base through hydraulic supports; a plurality of attached vibrators are fixed below the bottom surface of the bottom plate.

Further, the cam device comprises a motor, the motor is connected with a cam through a reduction gearbox, and the cam is connected to one end of the base through a crank.

Furthermore, two cam devices are arranged and arranged side by side.

Furthermore, protection plates are arranged on two sides of the die cavity and below the side baffle plates, and through holes are formed in the protection plates, so that the attached vibrator can be conveniently overhauled or replaced.

Compared with the prior art, the utility model discloses there is following beneficial effect:

the cam device is arranged, so that the vibration mould makes slow seesaw movement back and forth, and when the mould is inclined for a certain angle, the concrete utilizes the self weight to generate extrusion action to discharge air bubbles; meanwhile, the double functions of the self vibration of the mould are combined, so that more air bubbles in the concrete are discharged more quickly; when most of the bubbles are discharged, the density of the concrete is increased, and even a small amount of the bubbles are remained, the bubbles are compressed into very tiny small bubbles; finally, the appearance of the segment is improved, and the quality of the segment is improved.

The crank is arranged, so that the vibration die moves more stably; two cam devices which are arranged side by side are arranged, so that the cam devices alternately operate and have higher efficiency.
