Description

Изобретение относитс к производству железобетонных напорных труб.The invention relates to the production of reinforced concrete pressure pipes.

Целью изобретени вл етс улучшение качества гидропрессовани .The aim of the invention is to improve the quality of the hydraulic press.

На чертеже показана конструкци опоры. Опора содержит опорные элементы, каждый из которых выполнен в виде призматического башмака 1 с опорной поверхностью Л, наклоненной к горизонтали и во внутрь под углом 15-30°, который установлен шарнирно на стойке 2 со смеплением к его наружной стороне и имеет амортизатор 3 под основанием с внутренней стороны башмака 1. Стойка 2 закреплена на раме 4.The drawing shows the support structure. The support contains supporting elements, each of which is made in the form of a prismatic shoe 1 with a supporting surface L inclined to the horizontal and inwards at an angle of 15-30 °, which is pivotally mounted on a rack 2 with interfacing to its outer side and has a shock absorber 3 under the base on the inside of the shoe 1. The rack 2 is fixed on the frame 4.

Векторы нормальных сил от массы опираемой формы 5, приложенные к опорной поверхности А призматических башмаков 1, должны проходить через оси 6 шарниров или между ними. Из этого услови выбирают рассто ние между шарнирно-непод- вижными опорами- башмаков 1 на раме 4.The vectors of normal forces from the mass of the supported form 5, applied to the supporting surface A of the prismatic shoes 1, must pass through the axes 6 of the hinges or between them. From this condition, choose the distance between the hinge-fixed support-shoes 1 on the frame 4.

Форму 5 после заполнени литой бетонной смесью с помош.ью бетононасоса или другого устройства укладывают горизонтально на башмаки 1 и подключают к системе гидропрессовани . В процессе подъема давлени гидропрессовани до расчетной величины происходит раздвижка наружных частей формы 5 на величину 9-16 мм поAfter filling the cast concrete mix with the help of a concrete pump or other device, Form 5 is laid horizontally on the shoes 1 and connected to the hydraulic compression system. In the process of increasing the pressure of the hydraulic press to the calculated value, the outer parts of the form 5 are moved apart by an amount of 9-16 mm.

каждому из четырех разъемов в зависимости от диаметра формуемых труб, в результате чего наружный диаметр формы 5 увеличиваетс , и точки контакта формы 5 с опорной поверхностью А башмаков 1 перемешаютс к внешней стороне башмаков 1. При это.м благодар амортизаторам 3 каждый башмак 1 проворачиваетс на оси 6. За счет этого происходит перекатывание формы 5 по опорной поверхности А баш.маков 1, тем самым исключаетс ее проскальзывание по опорной поверхности А, ведущее к дополнительным энергозатратам.depending on the diameter of the tubular pipes, each of the four connectors increases as a result of which the outer diameter of the mold 5 increases and the points of contact of the mold 5 with the bearing surface A of the shoe 1 are mixed to the outside of the shoe 1. In this case, thanks to the shock absorbers 3, each shoe 1 turns on axis 6. Due to this, the mold 5 rolls over the supporting surface A of the bash.maks 1, thereby preventing it from slipping along the supporting surface A, leading to additional energy consumption.

Claims

The invention relates to the production of reinforced concrete pressure pipes. The aim of the invention is to improve the quality of the hydraulic press. The drawing shows the support structure. The support contains supporting elements, each of which is made in the form of a prismatic shoe 1 with a supporting surface L inclined to the horizontal and inwards at an angle of 15-30 °, which is pivotally mounted on a rack 2 with interfacing to its outer side and has a shock absorber 3 under the base on the inside of the shoe 1. The rack 2 is fixed on the frame 4. The vectors of normal forces from the mass of the supported form 5 applied to the supporting surface A of the prismatic shoes 1 must pass through the axes 6 of the hinges or between them. From this condition, choose the distance between the pivotally-fixed supports - shoes 1 on the frame 4. After filling the cast concrete mix with a concrete pump or other device, form 5 is placed horizontally on the shoes 1 and connected to the hydraulic pressing system. In the process of increasing the pressure of the hydraulic press to the calculated value, the outer parts of the form 5 are extended by 9-16 mm along each of the four connectors, depending on the diameter of the formed pipes, resulting in an increase in the outer diameter of the form 5 and the point of contact of the form 5 with the support surface A The shoes 1 are mixed to the outside of the shoes 1. At that, thanks to the shock absorbers 3, each shoe 1 rotates on the axis 6. Due to this, the form 5 rolls over the bearing surface A of the shoe 1, thereby eliminating Its slippage on the supporting surface A, leading to additional energy consumption. The invention of the device for hydraulic pressing of pressure pipes, contains, and supporting elements, each of which is hinged mounted on a rack mounted on a frame, characterized in that, in order to improve the quality of hydraulic pressing, each supporting element is made in the form of a prismatic shoe with a supporting surface inclined to the horizontal and inward at an angle of 15-30 °, mounted on a rack with a mixture to its outer side and has a shock absorber under the base on the inner side of the shoe.
