Description

противоположйую направлению движени устройства. Устройство работает следующим 6б разом. . - . На поверхност х лопастей 3, устано ленных под острым углом к продольной оси корпуса и к направлению потока А транспортируемой по трубопроводу образуетс сила F, разлагаема на две составл ющие: силу F , действующую по направлению качени опорных колес, и силу F, перпендикул рную к нему. СоСтавл юща Fj уравновешиваетс силой Трени FTP , образуемой между опорными колесами 5 и внутренней поверхностью трубопровода 1. в результате устройст во движетс под действием силы Р по Направлению ее действи , перемеща сь Й6 спирали . э;том плоскости качени Ъпорных колес наклонены под- острым уг лом в сторону, противоположную направлению движени устройства (аналогично ершику дл мойки бутылок). Наклонное положение вилок 4 и плоскостей качени опорных колес не мешает движению вперед, т. е. движению в направлении против потока среды. При значительных перепадах давлений среды, а также возможных резких увеличени х скоростей среды вилки с опорными колесами расклиниваютс иopposite the direction of movement of the device. The device works as follows 6b at a time. . -. On the surfaces of the blades 3, installed at an acute angle to the longitudinal axis of the housing and to the direction of flow A transported through the pipeline, a force F is formed, decomposing into two components: the force F acting in the rolling direction of the supporting wheels and the force F perpendicular to him The composition Fj is balanced by the FTP Traction force formed between the support wheels 5 and the inner surface of the pipeline 1. As a result, the device moves under the action of the force P in the Direction of its action, moving the H6 of the spiral. The rolling surface of the support wheels is inclined with an angled angle in the direction opposite to the direction of movement of the device (similar to a bottle brush). The inclined position of the forks 4 and the rolling surfaces of the support wheels does not interfere with the forward movement, i.e. the movement in the direction opposite to the flow of the medium. With significant pressure differences of the medium, as well as possible sharp increases in the velocities of the medium, the forks with the supporting wheels wedge and

Claims

785154 impede movement in the reverse direction) 1st ,; this eliminates the possible .f of the support wheels and the device itself in the direction of the actual flow of the medium. This also stabilizes the speed of movement of the device. Claim 1. Device for transporting goods through a pipeline in a stream of liquid or gas on the bus. St. No. 595938, characterized in that, in order to stabilize the speed of movement of the device against the flow by eliminating possible wheel drift in the direction of the flow of the medium with significant and abrupt pressure drops, the forks on which the support wheels are fixed are inclined at an acute angle to the longitudinal axis housing in the direction opposite to the direction of movement of the device. ,

2 .. The device according to p. 1, which is different from the fact that the support wheels and their forks are made of O: material. Sources of information taken into account in the examination 1. USSR author's certificate No. 585938, cl. B 65 G 51/00, 03.30.73.
