Изобретение относитс к производству напорных железобетонных труб со сталь-ным сердечником.This invention relates to the production of pressure reinforced concrete pipes with a steel core.

Известны тележки установок дл нанесени защитного покрыти на тела вращени , содержащие соединенные между собой жесткой т гой переднюю и заднюю части с закрепленными соответственно приводами перемещени тележки и вращени издели , закрепленного в упорах 1.Carts of installations for applying a protective coating on bodies of revolution are known, which comprise interconnected rigid, hard front and rear parts with, respectively, mounted drives for moving the carriage and rotating the product fixed in the stops 1.

Недостатком известных тележек вл етс невозможность изготовлени изделий различных диаметров.A disadvantage of the known carts is the impossibility of manufacturing products of various diameters.

Цель изобретени - обеспечение возможности изготовлени изделий различного диаметра.The purpose of the invention is to enable the manufacture of products of different diameters.

Указанна цель достигаетс тем, что тележка, к установке дл нанесени защитного покрыти на тела вращени , содержаща соединенные между собой жесткой т гой переднюю и заднюю части с закрепленными соответстврнно приводами перемещени тележки и вращени издели , за .крепленного в упорах, снабжена приспособлеиием вертикальных и поперечных горизонтальных перемепюнин в виде закрепленных на ее передней и .1дней част х нелодвижных клиньев и опертых на них приводных подвижных клиньев, причем на последних жестко закреплены упоры и привод вращени изделий.This goal is achieved by the fact that the carriage, to the installation for applying a protective coating on rotation bodies, containing interconnected rigid front and rear parts with appropriately mounted drives for moving the carriage and rotating the product fastened in stops, is equipped with vertical and transverse horizontal remepyunin in the form of non-movable wedges fixed on its front and .1 days, and movable driving wedges supported on them, with stops and a drive fixed on the latter rotation of products.

На фиг. 1 схематично изображена тележка к установке дл нанесени защитногоFIG. 1 schematically shows a trolley for a protective installation.

5 покрыти на тела вращени , общий вид; на фиг. 2 - вид А на фиг. 1.5 coatings on rotating bodies, general view; in fig. 2 is a view A of FIG. one.

Тележка к установке дл нанесени защитного покрыти на тела вращени установлена на рельсовом пути 1 и состоит изA trolley to the installation for applying a protective coating on the bodies of rotation is mounted on the track 1 and consists of

.- двух тележек 2 и 3, на которых соответственно закреплен привод 4 перемещени тележки и привод 5 вращени издели , соединенные между собой жесткой т гой 6. Изменение длины жесткой т ги позвол ет производить |1анесение защитного покрыти .- two carts 2 and 3, on which, respectively, the drive 4 of the trolley and the drive 5 of rotation of the product are fixed, interconnected by a rigid thrust 6. Changing the length of the hard thrust allows the protective coating to be applied.

5 на трубы различной длины. На каждой из тележек 2 и 3 установлено устройство, выполненное в виде двух пар клиньев 7 и 8. При этом клинь 7 вл ютс основанием дл передней 9 и задней 10 бабок, в которых закрепл етс труба 11, а клинь 85 on pipes of various lengths. On each of the carts 2 and 3, a device is installed, made in the form of two pairs of wedges 7 and 8. In this case, the wedge 7 is the basis for the front 9 and the rear 10 of the heads in which the pipe 11 is fixed, and the wedge 8

Claims

20 are installed on trolleys 2 and 3. The movement of the wedges 7 relative to the wedges 8 is carried out by the feeding mechanism 12. A fixed connection of the wedges 7 and 8 relative to each other after adjustment is provided by the stops 13. And the fixed wedge 8 is mounted on the scale 14, on which divisions are applied , corresponding to the diameters of the pipes, and pas movable wedge 7 - arrow 15. The installation of the installation for applying a protective coating on the body of rotation, such as a pipe, is carried out as follows. It is necessary to loosen the fasteners of the stops 13. The feeding mechanism 12 moves the movable wedge 7 relative to the fixed wedge 8 until the arrow 15 is aligned with the division of the boards 14 corresponding to the given pipe diameter. In this case, the axis of symmetry of the torch always passes through the center of the pipe 11, and the length of the torch (the distance from the base of the torch to the surface of the pipe) is constant, independent of the diameter of the pipe being manufactured. Then tighten stops 13. The unit is ready for operation. The use of the invention makes it possible to manufacture pipes of different diameters in one installation for applying a protective coating. The claims to the installation for applying a protective coating on the rotation bodies, comprising interconnected rigid front and rear parts with fixed respectively to the movement of the trolley movement and rotation of the product fixed in stops, characterized in that products of various diameters, it is equipped with a device of vertical and transverse horizontal displacements in the form of fixed wedges fixed on its front and back parts and supported on. They are driven by moving wedges, with the stops and the drive of the rotation of the products fixed on the latter. Sources of information taken into account during the examination 1.
