Title (EN) DEVICE FOR CLEANING INNER SURFACE OF PIPE
(FR) DISPOSITIF DE NETTOYAGE DE SURFACE INTÉRIEURE DE TUYAU
(ZH) 一种管道内表面清洁装置
Abstract:
(EN) A device for cleaning the inner surface of a pipe, comprising a transmission flexible shaft (100), a support (200), a driving device (300), and a cleaning assembly (500). The transmission flexible shaft (100) is provided with opposite first and second ends; the support (200) is circular and is coaxially connected to the first end; several rollers in contact with the inner wall of the pipe (1) are arranged at the periphery of the support (200) at intervals; the driving device (300) is connected to the second end, and can transfer a torque force to the support (200) by means of the transmission flexible shaft (100), so as to drive the support (200) to move along the length direction of the pipe (1); the cleaning assembly (500) is positioned at one side of the support (200) away from the driving device (300), and is coaxially connected to the support (200). The device for cleaning the inner surface of a pipe can convey the cleaning assembly (500) to a preset position so as to observe the inner surface of the pipe (1) by means of the cleaning assembly (500), and can also place an object to be conveyed in front of the support (200) along a movement direction thereof so that the support (200) conveys the object to be conveyed to a target position. Compared with the prior art, it is not required to dismount or cut a pipe, and thus a lot of manpower, material resources, and time can be saved.
(FR) Dispositif de nettoyage de la surface intérieure d'un tuyau, comprenant un arbre flexible de transmission (100), un support (200), un dispositif d'entraînement (300) et un ensemble de nettoyage (500). L'arbre flexible de transmission (100) est pourvu de première et seconde extrémités opposées ; le support (200) est circulaire et est relié de manière coaxiale à la première extrémité ; plusieurs rouleaux en contact avec la paroi intérieure du tuyau (1) sont agencés à la périphérie du support (200) à des intervalles ; le dispositif d'entraînement (300) est relié à la seconde extrémité, et peut transférer une force de couple au support (200) au moyen de l'arbre flexible de transmission (100), de manière à entraîner le support (200) à se déplacer le long de la direction de la longueur du tuyau (1) ; l'ensemble de nettoyage (500) est positionné sur un premier côté du support (200) à l'opposé du dispositif d'entraînement (300), et est relié de manière coaxiale au support (200). Le dispositif de nettoyage de la surface intérieure d'un tuyau peut transporter l'ensemble de nettoyage (500) vers une position prédéfinie de façon à observer la surface intérieure du tuyau au moyen de l'ensemble de nettoyage (500), et peut également placer un objet devant être transporté devant le support (200) le long d'une direction de déplacement de celui-ci de telle sorte que le support (200) transporte l'objet à transporter vers une position cible. Par comparaison avec l'état de la technique, il n'est pas nécessaire de démonter ni de couper un tuyau, ce qui permet d'économiser beaucoup de main d'oeuvre, de ressources matérielles et de temps.
(ZH) 一种管道内表面清洁装置,包括传动软轴(100)、支架(200)、驱动装置(300)及清洁组件(500),传动软轴(100)具有相对的第一端和第二端;支架(200)为圆形且与第一端同轴连接,支架(200)的外周间隔设置有若干与管道(1)的内壁接触的滚轮;驱动装置(300)与第二端连接,驱动装置(300)可通过传动软轴(100)将扭力传递至支架(200),以驱动支架(200)沿管道(1)的长度方向运动;清洁组件(500)位于支架(200)远离驱动装置(300)的一侧,并与支架(200)同轴连接。该管道内表面清洁装置,可以实现将清洁组件(500)输送至预定位置,通过清洁组件(500)对管道(1)的内表面进行观察,还可以将待运输的物体放置在支架(200)的运动方向的前方,通过支架(200)将待运输的物体运输至目标位置,与现有技术相比,不需要对管道进行拆除或者切割处理,可以节省大量的人力、物力及时间。
