Изобретение относитс к производству иэ изделий из бетопа и железобетона.The invention relates to the manufacture of concrete products from concrete and reinforced concrete.

Известна виброплошадка, содержаща подвижную pavy, установленную на упругих опорах , и возбудитель колебаний, например, электромагн итны{ подвешенный к подвижной раме с помощью упругих элементов 1J . Недостатком такой виб роплощадки вл етс низка эффективность уплотнени безударного характера колебаний. The vibratory plate is known, containing a movable pavy mounted on elastic supports and a vibration exciter, for example, an electromagnetic [not suspended to a movable frame by means of elastic elements 1J. The disadvantage of such a vibration platform is the low efficiency of the compaction of the unstressed nature of oscillations.

Наиболее близка к предлагаемому изобретению виброплощадка содержит установленную на упругих опорах подвижную раму с центральным окном, к которой при помощи упругих элементов подвешен ударник с дебалансным возбудителем колебашш и буферными элементами, взаимодействуюшими с формой через окно в подвижной раме, путем ударов о днище формы 2 .Closest to the proposed invention, the vibrating platform contains a movable frame mounted on elastic supports with a central window to which a drummer with an unbalanced oscillator and buffer elements interacting with the form through a window in the movable frame is suspended by means of blows against the bottom of the form 2.

Однако необходимость креплени формы с бетонной к подвижной раме с помощью Отдельного захватного механизма усложн ет конструкцию такой виброплощадкиHowever, the need to attach the mold from the concrete to the movable frame using a Separate gripping mechanism complicates the design of such a vibrating plate.

Цель изобретени - упрощение конструкции виброплошадки..The purpose of the invention is to simplify the design of the vibrating plate.

Это достигаетс тем, что в виброплошаоке , содержащей установленную на упругих опорах подвижную раму с центральным окном к которой при помощи упругих элементов подвешен ударник с возбудителем колебаний и буферными элементами, возбудитель колебаний выполт1ен электромагни THUNI, а корь его размещен в окне подвижной рамм и закреплен на днище формы.This is achieved by the fact that in a vibrating plate containing a movable frame mounted on elastic supports with a central window to which, using elastic elements, a drummer with an exciter and buffer elements is suspended, the exciter is removed by a THUNI electromagnet, and the measles are placed in the movable frame window and fixed to bottom of the form.

На чертеже схематически изображена предлагаема виброплошадка, общий вип.The drawing shows schematically the proposed vibrating plate, a common VIP.

Claims

The vibrating plate contains a movable frame 1. mounted on elastic supports 2. A drummer 4 is suspended on the movable frame on elastic elements 3, on which is mounted an electromagnet) and an exciter exciter 5. The movable 1 is made with a constant window 6 located opposite the electromagnetic exciter of oscillation 5 The anchor 7 of the electromagnetic excitement exciter is placed in OKTie 6 and is fixed on the bottom of the form 8, freely mounted on the movable frame 1. The buffer elements 0 are located on the impactor. The vibrating plate works as follows. A movable frame 1 is installed on the form 8. A pulsating current is applied to the winding of the electromagnetic exciters 5. creating a pulsating power of gi between, an electromagnetic exciter of oscillations 5 and its core 7; The variable component of the electromagnetic vibration exciter exciter 5 excites the impactor 4, antiphase oscillations of the form 8 and the moving frame 1 and is accompanied by blows through the buffer elements 9 The constant electromagnetic propulsion force 5 of the oscillator 5 oscillates the form 8 against the mobile frame 1, preventing the mold from taking off the frame. Fixing the core 7 of the electromagnetic exciter at the bottom of the mold 8 simplifies the construction of the vibration platform, since it allows one to get rid of the gripping mechanism for fastening the mold. Claims of the invention A vibrating platform for compacting concrete mixes in a mold containing a movable frame mounted on elastic supports with a central window to which a hammer with oscillator and buffer elements is suspended by elastic elements, in order to simplify the design, the oscillator is electromagnetic , and its measles is placed in a window of a mobile frame and fixed on the bottom of a form.
