Abstract: A scraper for removing deposits from the exterior of a tubular member includes elements defining an outer jacket which has an inwardly open circumferential recess and two aligned axial openings, and a scraper element in the form of an elongate resilient wire bent to define a series of integral, concatenated, resilient segments, each pair of adjacent segments being connected through a bend or geniculation. All geniculations are received within the recess, and each segment of wire extends generally along a chord of the aligned axial openings. The positions of the chords are distributed around the circumference of the axial openings such that, in order for the tubular member to be accommodated through the aligned openings, the various segments must be deformed outwardly, whereby the resilience of the thus deformed segment urges it inwardly against the tubular member, and causes it to clean the tubular member as the scraper moves axially.
Abstract translation: 用于从管状构件的外部去除沉积物的刮刀包括限定外护套的元件，外护套具有向内开口的周向凹部和两个对准的轴向开口，以及细长弹性线形式的刮板元件，其被弯曲以限定一系列积分 连接的弹性片段，每对相邻的片段通过弯曲或铰链连接。 所有的接合处都被容纳在凹槽内，并且每个丝线段大致沿对齐的轴向开口的弦线延伸。 弦杆的位置围绕轴向开口的圆周分布，使得为了使管状构件通过对准的开口容纳，各个片段必须向外变形，由此变形的片段的弹性将其向内推动 抵靠管状构件，并且当刮刀沿轴向移动时使其清洁管状构件。

Abstract: Un raspador (9) para la eliminación de depósitos del exterior de un miembro tubular, que comprende: una envuelta (10) exterior que define un entrante (30) circunferencial abierto hacia dentro y dos aberturas (32) axiales alineadas; un elemento (12) de raspador en forma de alambre resiliente alargado doblado para definir una serie de segmentos (26) resilientes concatenados integrales, estando conectados cada par de segmentos por medio de una doblez (28) siendo recibida la doblez dentro de dicho entrante (20) con al menos un segmento (26a) extendiéndose sustancialmente a lo largo de una cuerda de las aberturas (32) axiales alineadas por medio de lo cual, para dar cabida al miembro tubular a través de dichas aberturas axiales alineadas, el miembro tubular debe deformar dicho al menos un segmento hacia fuera, de manera que la elasticidad del segmento lo fuerza hacia dentro contra el miembro tubular y hace que limpie el miembro tubular a medida que el raspador se desplaza axialmente respecto delmiembro tubular.

Abstract: Un raspador (9) para retirar depositos del exterior de un miembro (34) tubular incluye elementos que definen un casquillo (10) exterior el cual tiene un rebajo circunferencial abierto hacia adentro y dos aberturas alineadas en forma axial, y un elemento (12) raspador en forma de un alambre elastico alargado doblado para definir un grupo de segmentos (26) elasticos concatenados e integrales, cada par de segmentos adyacentes esta conectado a traves de una curva o articulacion (28) doblada. Todas las articulaciones (28) dobladas se reciben dentro del rebajo y cada segmento (26a) de alambre se extiende por lo general a lo largo de un cordon de las aberturas alineadas en forma axial. Las posiciones de los cordones estan distribuidas alrededor de la circunferencia de las aberturas axiales, con el fin de que el miembro (34) tubular se acomode a traves de las aberturas alineadas, los diversos segmentos (26a) se deben deformar hacia afuera, por lo cual la elasticidad del segmento deformado lo impulsa hacia adentro contra el miembro (34) tubular y provoca que limpie el miembro (34) tubular conforme el raspador se mueve en forma axial.

Abstract: A scraper 9 for removing deposits from the exterior of a tubular member 34 includes elements defining an outer jacket 10 which has an inwardly open circumferential recess and two aligned axial openings, and a scraper element 12 in the form of an elongate resilient wire bent to define a series of integral, concatenated, resilient segments 26, each pair of adjacent segments being connected through a bend or geniculation 28. All geniculations 28 are received within the recess, and each segment 26a of wire extends generally along a chord of the aligned axial openings. The positions of the chords are distributed around the circumference of the axial openings such that, in order for the tubular member 34 to be accommodated through the aligned openings, the various segments must be deformed outwardly, whereby the resilience of the thus deformed segment urges it inwardly against the tubular member 34, and causes it to clean the tubular member 9 as the scraper moves axially.
