Description

/ 1./ one.

Изобретение относитс к производству трубчатых изделий из бетонных смесей.The invention relates to the production of tubular products from concrete mixtures.

Известна установка дл формовани тел вращени из бетонных смесей, содержаща ременную центрифугу с формой, возбудитель горизонтальных колебаний, установленный на резонаторе, св занном через упругие элементы, и упорный стержень с планшайбой, закрепленной на торце формы .A known apparatus for forming rotational bodies from concrete mixtures, comprising a belt centrifuge with a shape, a horizontal oscillation pathogen mounted on a resonator connected through elastic elements, and a stop rod with a face plate fixed to the end of the mold.

Недостатком указанной установки вл етс значительна трудоемкость соединени возбудител колебаний с формой, осуществл емого после установки формы на центрифугу. Другим недостатком этой установки вл етс интенсивный износ упорного стержн , с помощью которого жестко соединены планшайба и резонатор.The disadvantage of this installation is the significant complexity of the connection of the vibration exciter with the form, carried out after the installation of the form on the centrifuge. Another disadvantage of this setup is the intense wear of the stop bar, with which the faceplate and the resonator are rigidly connected.

Целью изобретени вл етс повышение надежности и удобства обслуживани установки .The aim of the invention is to improve the reliability and ease of maintenance of the installation.

Указанна цель достигаетс тем, что в установке, содержащей ременную центрифугу с формой, возбудитель горизонтальных продольных колебаний, установленный на резонаторе, св занном через упругие элементы и упорный стержень с планшайбой , закрепленной па торце формы, упорный стержень выполнен составным из соединенных при помощи приводного клинового зажима частей, одна из которых закреплена посредством подшипника на планшайбе .This goal is achieved by the fact that in a device containing a belt centrifuge with a shape, a horizontal longitudinal oscillation pathogen mounted on a resonator connected through elastic elements and an anvil rod with a faceplate fixed on the mold face, the anvil rod is made of a composite wedge-shaped wedge clamping parts, one of which is fixed by means of a bearing on the faceplate.

На чертеже схематически изображена установка дл формовани тел вращени из бетонных смесей.The drawing shows schematically an apparatus for forming rotation bodies from concrete mixtures.

Установка содержит форму 1, размещенную на ремп х 2 центрифуги (условно не показана), и возбудитель 3 горизонтальныхThe installation contains form 1, placed on a rep x 2 centrifuge (conventionally not shown), and the pathogen 3 horizontal

продольных колебаний, установленный на резонаторе 4, св занном через упругие элементы 5 и упорный стержень с планшайбой 6 формы 1. В планшайбе 6 смонтирован подшипник 7, воспринимающий радиальные и осевые нагрузки. Упорный стержень 8 выполнен составным из двух частей: правой, состо щей из вала 9 и жестко посаженной на него рабочей плиты 10, и левой, выполненной в виде вала 11, соединенного с подшипником 7. Обе части 8 и И упорного стержн соединены между собой приводным клиновым зажимом 12, св занным с приводом 13. Возбудитель 3 и резонатор 4 смонтированы на упругой подвеске 14.longitudinal oscillations mounted on the resonator 4, connected through elastic elements 5 and the stop rod with the faceplate 6 of the form 1. In the faceplate 6 is mounted a bearing 7, which perceives radial and axial loads. The thrust rod 8 is made up of two parts: the right, consisting of a shaft 9 and a working plate 10 rigidly mounted on it, and the left, made in the form of a shaft 11 connected to a bearing 7. Both parts 8 and And of a stop rod are interconnected by driving a wedge clamp 12 connected to the drive 13. The exciter 3 and the resonator 4 are mounted on an elastic suspension 14.

Установка работает следующим образом .The installation works as follows.

Claims

The wedge clamp 12 through the actuator 13 is lifted to the upper position. After installing the mold 1 on the belts 2 of the centrifuge, the shaft is connected to the right side of the anvil strut by means of a wedge clamp 12, for which it is lowered into the lower position. Then turn on the centrifuge drive and the causative agent of 3 oscillations, in a rotating form serves the concrete mix. In this case, oscillations from the exciter 3 through the resonator 4, the elastic elements 5 are transmitted to the working plate 10 and the shaft 9. The oscillations of the shaft 9 through the wedge clamp 12 are transmitted to the shaft 11 and through the bearing 7 and the faceplate 6 to the form 1. At the end of the molding process the exciter is turned off vibrations 3 and disconnect the wedge clamp 12, the form with the product is removed and transferred to the post heat treatment. Such a structure of the installation makes it possible to significantly simplify the process of joining the mold with the oscillation pathogen, also in this case the non-rotating elements are joined: shaft 11 and clamp 12. The execution of the working plate in the form of a shaft mixed in the bearings simplifies the design of the vibration exciter and raises 5 10 15 20 25 & t reliability because in this case the need for wear-resistant rods present in conventional horizontal vibration exciters is eliminated. The invention The apparatus for forming rotation bodies from concrete mixtures, comprising a belt centrifuge with a shape, a horizontal longitudinal oscillation pathogen mounted on a resonator connected through elastic elements and a stop rod with a faceplate fixed to the end of the mold, characterized in that increase reliability and ease of maintenance, the thrust rod is made of composite parts connected by means of a drive wedge clamp, one of which is fixed by means of a bearing on the faceplate.
