Description

Изобретение относитс  к сварке пластмасс, а именно к устройствам дл  сварки трубопроводов из полимерных материалов.The invention relates to the welding of plastics, in particular to devices for welding pipelines of polymeric materials.

Известно устройство дл  стыковой сварки термопластических труб, содержсццее инструмент - нагреватель, вьшолненный в виде двух одинаковых пластин с полукруглыми вырезами, установленных с возможностью пр молинейного возвратно-поступательного движени  l3.A device for butt welding of thermoplastic pipes is known; the tool containing the heater is made in the form of two identical plates with semicircular cuts installed with the possibility of a straight-forward reciprocating motion l3.

Недостаток ус.тройства состоит в высокой стоимости проклгщки трубопроводов .The disadvantage of the device is the high cost of pipelines.

Этот недостаток обусловлен повышенными габаритами устройства, влекущими за собой увеличение объема земл ных работ при прокладке траншеи .This disadvantage is due to the increased dimensions of the device, which entail an increase in the volume of earthworks during the laying of the trench.

Известно устройство дл  сварки пластмассовых труб, содержащее разжимные элементы смонтированные на трубчатом корпусе, и нагревательные элементы Г21.A device for welding plastic pipes is known, comprising expanding elements mounted on a tubular body and heating elements G21.

Недостатком такого устройства  вл етс  также высока  стоимость прокладки трубопроводов. Это недостаток обусловлен большими габаритами устройства, так как нагреватель после оков 1ани  процесса нагрева удал етс  с внешней стороны трубы и дл  обеспечени  этой операции требуетс  широка  и глубока  транше .The disadvantage of such a device is also the high cost of laying pipelines. This disadvantage is due to the large dimensions of the device, since the heater after the shackles of the heating process is removed from the outside of the pipe and a wide and deep trench is required for this operation.

Целью изобретени   вл етс  снижение стоимости-при прокладке трубопроводов за счет уменьшени  габаритов устройства.The aim of the invention is to reduce the cost-when laying pipelines by reducing the size of the device.

The device consists of a tubular body 1, on which are mounted, expanding elements 2 and hollow guides 3, in which are mounted spring-loaded rods 4, to which heating elements 5 and cables 6 passing in grooves 7 and placed in tubular body 1 are attached. The proposed device works as follows. The tubular body 1 rolls into the inside of the pipes to be welded, and the heating elements 5 are pressed against the surfaces to be welded. The minimum number of heating elements ensuring the uninterrupted operation of the device is three or more. The heating elements are nichrome, wafer plates bent along a certain radius of curvature. The installation of the heating element 5 in the desired position is achieved by adjusting the position of the spring-loaded rod 4 using a cable b attached to the rod 4 and passing in the groove 7. When heated, the expandable elements 2 abut against the pipes to be welded. After the heating process is completed, the heating elements 5 are retracted inwards by pulling the cables, the spring-loaded rods 4 go into the hollow guides 3. Then, by displacing the expanding elements 2 relative to the tubular body 1, the final pressing of the welded surfaces is achieved. the housing rolls out of the pipe. The proposed device has the following advantage: all the nodes of the inner heating apparatus are located inside the welded uruba, due to which the dimensions of the device and, consequently, the trenches are reduced. Claims of the invention A device for welding plastic-plastic pipes containing expansion elements mounted on a tubular body and heating elements, characterized in that, in order to reduce the cost of laying pipelines due to the reduction of the dimensions of the device, it is provided with spring-loaded rods installed in hollow directions. mounted on a tubular body and cables fixed at one end on spring-loaded rods and placed in a tubular body, and the heating elements mounted on rods .
