Description

Известны устройства дл  удалени  из тела коллектора или барабана парового котла обрезанных труб посредством самозаклинивающегос  захвата, развальцованной части трубы и извлечени  трубы винтовым домкратом.Devices are known for removing cut-off pipes from a collector body or a drum of a steam boiler by means of a self-jamming gripping part of a pipe and extracting the pipe with a screw jack.

Отличительной особенностью устройства по данному изобретению  вл етс  применение закрепленных на винте домкрата с помощью пружины клиньев, расположенных Л1ежду наклонными плоскост ми, образованными нижней частью винта и внутренней поверхностью трубы.A distinctive feature of the device according to the present invention is the use of wedges fixed on the screw of the jack by means of a spring, arranged between the inclined planes formed by the lower part of the screw and the inner surface of the pipe.

Конструкци  устройства по данному изобретению представлена на прилагаемом черт-еже.The structure of the device according to the invention is shown in the attached hell.

Колпачок 1 надеваетс  на развальцованную часть трубы. Через отверстие колпачка внутрь трубы пропущен винт 2. колпачком и развальцованной частью трубы закладываетс  прокладка 3, закрепленна  посредством пружины 6.The cap 1 is put on the flared portion of the pipe. A screw 2 is passed through the opening of the cap into the pipe. A cap 3 is laid by the cap and the flared part of the pipe, fixed by means of a spring 6.

Между наклонными плоскост ми нижней части винта 2 и внутренней поверхностью трубы установлены клинь  4, закрепленные на винте с помощью пружины 5. Опора 7 с приваренным донышком 8 воспринимает через сферическую шайбу 5 усилие от гайки 10. Дл  вращени  гайки предусмотрен универсальный шарнир, состо щи из кольца //, винтов 12 и вилки J3. К вилке 13 приварено донышко 14, к которому крепитс  скалка 15 с квадратом на верхнем конце под вороток или ключ-трещетку .A wedge 4 is mounted between the inclined planes of the bottom of the screw 2 and the inner surface of the pipe using a spring 5. The support 7 with the welded bottom 8 receives through the spherical washer 5 the force from the nut 10. A universal hinge is provided for rotating the nut. rings //, screws 12 and forks J3. A bottom 14 is welded to the plug 13, to which is attached a rolling pin 15 with a square at the upper end under the key or ratchet key.

Предмет изобретени Subject invention

Устройство дл  извлечени  отрезков развальцованных труб из коллекторов с применением винтового домкрата, отличающеес  тем, что, с целью самозаклинивани  трубы при извлечении ее из коллектора, применены закрепленные на винте домкрата с помощью пружины клинь , расположенные между наклонными плоскост ми нижней части винта и внутренней поверхностью трубы.A device for extracting flared pipe sections from collectors using a screw jack, characterized in that, in order to self-jam the pipe when removing it from the collector, a wedge fixed to the screw of the jack is used, located between the inclined planes of the lower part of the screw and the inner surface of the pipe .
