Closest to the proposed is a centrifuge for forming bodies of revolution from concrete mixtures, containing a drive horizontal form with an additional shell mounted on a support with elastic collars and restrictive rollers in contact with the additional shell of the form and located symmetrically to its longitudinal axis.

Недостатками указанных центрифуг является сложность конструкции, а «отсюда сложность в обслуживании и ненадежность .The disadvantages of these centrifuges are the complexity of the design, and "hence the difficulty in maintenance and unreliability.

Цель изобретения - упрощение конструкции и повышение надежности.The purpose of the invention is to simplify the design and increase reliability.

Указанная цель достигается тем, что в центрифуге для формования тел · вращения из бетонных смесей, содержащей приводную горизонтальную форму с дополнительной оболочкой, установленной на опоре с эластичными воротниками и ограничительными катками, контактирующими с дополнительной оболочкой формы и расположенными симметрично ее продольной оси, опора выполнена в виде заполненной жидкостью камеры, дополнительная оболочка формы - герметичной, а ограничительные катки - подпружиненными.This goal is achieved by the fact that in a centrifuge for molding bodies of revolution · from concrete mixtures containing a horizontal drive form with an additional shell mounted on a support with elastic collars and restrictive rollers in contact with the additional shell of the form and located symmetrically to its longitudinal axis, the support is made in in the form of a chamber filled with liquid, the additional shell of the mold is sealed, and the limiting rollers are spring-loaded.

На фиг. I схематически изображена центрифуга для формования тел вращения из бетонных смесей, общий вид в разрезе; на фиг. 2 - разрез А-А на фиг. I.In FIG. I schematically shows a centrifuge for forming bodies of revolution from concrete mixtures, a General view in section; in FIG. 2 is a section AA in FIG. I.

Центрифуга для формования тел вращения из бетонных смесей состоит из опорной рамы I, камеры 2, заполненной ' жидкостью 3, кронштейнов 4, пружин 5, ограничительных катков 6 и 7, эластич-The centrifuge for forming bodies of revolution from concrete mixtures consists of a support frame I, a chamber 2 filled with fluid 3, brackets 4, springs 5, restriction rollers 6 and 7, elastic

10. Камера 2 установлена на опорной раме 1.10. The camera 2 is mounted on a support frame 1.

, Форма 10 выполнена с дополнительной наружной цилиндрической оболочкой ₅11', внутренняя и наружная обечайки которой образуют герметичную полость. Оболочка 11 смонтирована между ограничительными катками 6 и 7., Form 10 is made with an additional outer cylindrical shell ₅ 11 ', the inner and outer shells of which form an airtight cavity. The shell 11 is mounted between the limiter rollers 6 and 7.

II

Ограничительные катки 6 и 7 установлены на горизонтально подвижных кронштейнах 4 симметрично продольной · оси формы 10 и оперты .на пружины 5 с целью постоянного контакта с формой 10 при загрузке ее бетонной смесью.Limit rollers 6 and 7 are mounted on horizontally movable brackets 4 symmetrically to the longitudinal axis of the mold 10 and are supported on the spring 5 in order to constantly contact the mold 10 when loading it with concrete mix.

Работает центрифуга для формования тел вращения следующим образом.A centrifuge operates to form bodies of revolution as follows.

Подготовленную форму 10 с наружной герметичной цилиндрической оболочкой 11 устанавливают в камеру 2, наполненную жидкостью. При этом ограничительные катки 6 и 7 препятствуют перемещению формы в продольном и поперечном направлениях» Оболочка 11 выполняет роль поплавка и погружена в жидкость на величину, определяемую весом формы и оболочки.The prepared form 10 with the outer sealed cylindrical shell 11 is installed in the chamber 2 filled with liquid. At the same time, the limiting rollers 6 and 7 prevent the mold from moving in the longitudinal and transverse directions. ”Shell 11 acts as a float and is immersed in the liquid by an amount determined by the weight of the mold and shell.

Двигатель 9 приводит форму во .вращение и в нее подается бетонная смесь.The motor 9 rotates the mold and concrete mixture is fed into it.

* Величина погружения оболочки 11 с формой 10 увеличивается, при этом контакт ограничительных катков 6 и 7 с формой обеспечивается за счет пру18 4 ясин 5. Бетонная смесь равномерно уплотняется пс внутренней поверхности формы.* The immersion value of the casing 11 with the mold 10 increases, while the contact of the limiter rollers 6 and 7 with the mold is ensured by the rod 18 4 yasin 5. The concrete mixture is uniformly compacted ps the inner surface of the mold.

Применение предлагаемого устройства позволит упростить конструкцию и повысить надежность центрифуг, применяемых для формования тел вращения из бетонных смесей.The application of the proposed device will simplify the design and increase the reliability of the centrifuges used for forming bodies of revolution from concrete mixtures.

Claims

This invention relates to the manufacture of precast concrete and reinforced concrete products. A known centrifuge for molding rotational bodies from concrete mixes, containing a frame with restrictive rollers and a support for setting the CO shape. The closest to the present invention is a centrifuge for molding rotational bodies from concrete mixes, containing a driven horizontal FO1... with an additional casing installed on a support with elastic collars and restrictive rollers in contact with an additional shell of the form and located symmetrically to its longitudinal axis C2j. The disadvantages of these centrifuges are the complexity of the design, and "hence the difficulty in servicing and the lack of reliability. The purpose of the invention is to simplify the design and increase reliability. This goal is achieved by the fact that in a centrifuge to form rotation bodies from concrete mixes, containing a horizontal drive form with an additional shell mounted on a support with elastic collars and restrictive rollers that are coded with an additional shell form symmetrically arranged in its longitudinal axis, the support is as in the chamber filled with liquid, the additional form-in-1 shell is hermetic, and the limiting rollers are spring-loaded. FIG. I schematically depicts a centrifuge for forming rotation bodies from concrete mixtures, a general view in section; Fig. 2 shows a section A-A on, 1. A centrifuge for forming rotation bodies from concrete mixtures consists of a support frame 1, a chamber 2 filled with liquid 3, brackets 4, springs 5, limiting rollers 6 and 7, elastic collars 8, drive 9 and form 10. Chamber 2 is mounted on support frame I with Form 10 is made with an additional cylindrical outer shell 11, the inner and outer shells of which form an airtight cavity. The shell 11 is mounted between the limiting rollers 6 and 7, Restrictive rollers 6 and 7 are mounted horizontally movable the brackets 4 are symmetrical to the longitudinal axis of the form 10 and supported on the spring 5 in order to make permanent contact with the form 10 when it is loaded with a concrete mix. A centrifuge is used to form the bodies of rotation as follows. The prepared form 10 with an externally hermetic cylindrical shell 1 is installed in the chamber 2, on the filled with liquid. In this case, restriction rollers 6 and 7 prevent the form from moving in the longitudinal and transverse directions. The shell 11 plays the role of a float and is immersed in a liquid by an amount determined by the weight of the form and the shell. Engine 9 leads form in. rotation and a concrete mixture is fed into it. The amount of immersion of the shell 11 with the mold 10 is increased, while the contact of the restriction rollers 6 and with the mold is ensured by the spring of the core 5. The concrete mix is uniformly compacted by the inner surface of the mold. The use of the proposed device will simplify the design and increase the reliability of the centrifuges used to form rotation bodies from concrete mixtures. Claims of the invention A centrifuge for forming rotational bodies from concrete mixes, comprising a drive horizontal form with an additional shell mounted on a support with elastic collars and restriction rollers in contact with the additional shell of the form and located symmetrically with its longitudinal axis, so that construction and increase of reliability, the support is made in the form of a chamber filled with liquid, the additional shell of the form is hermetic, and the restraining rollers - the spring by the data.
