Disclosed is a telescopic mast with built-in belt ropes. The telescopic mast with built-in belt ropes according to the present invention comprises: a plurality of joint bodies having different outer diameters; a plurality of belt ropes connecting the joint bodies in order to operate the joint bodies simultaneously; collar portions which are coupled to the top of each joint body and in which guide rollers for guiding the movement of the belt ropes are embedded in one side thereof and the other side on an opposite portion thereof; a belt rope stator which is coupled to the bottom of a lowermost joint body having the largest diameter among the plurality of joint bodies, and to which both ends of any one belt rope are fixed; and belt rope guides which are coupled to the bottom of each joint body excluding the lowermost joint body, and to which both ends of any one belt rope are fixed and the other belt rope is movably coupled, wherein the plurality of joint bodies are assembled to overlap each other so as to form a telescopic structure of which the length is adjustable, and wherein the belt ropes, excluding a lowermost belt rope among the plurality of belt ropes, are connected to two joint bodies spaced apart from each other with one joint body in the middle therebetween, wherein the belt ropes connected to the two bodies spaced apart from each other are configured to pass through the inside of the joint body positioned in the middle of the two joint bodies to which the belt ropes are connected.

L'invention concerne un mât télescopique à cordes de courroie intégrées. Ledit mât télescopique à cordes de courroie intégrées selon la présente invention comprend : une pluralité de corps de joint ayant différents diamètres externes ; une pluralité de cordes de courroie reliant les corps de joint afin de les faire fonctionner simultanément ; des parties de collier qui sont couplées à la partie supérieure de chaque corps de joint et dans lesquelles des rouleaux de guidage pour guider le mouvement des cordes de courroie sont intégrés d'un côté à celles-ci et de l'autre côté sur une partie opposée à celles-ci ; un stator de corde de courroie qui est accouplé au fond d'un corps de joint le plus bas ayant le plus grand diamètre parmi la pluralité de corps de joint, et auquel les deux extrémités de n'importe quel corde de courroie sont fixées ; et des guides de corde de courroie qui sont accouplés au fond de chaque corps de joint à l'exclusion du corps de joint le plus bas, et auxquels les deux extrémités de n'importe quel corde de courroie sont fixées et l'autre corde de courroie est accouplée de façon mobile. La pluralité de corps de joint est assemblé pour se chevaucher de façon à former une structure télescopique dont la longueur est réglable, et les cordes de courroie, à l'exclusion du corde de courroie la plus basse parmi la pluralité de cordes de courroie, sont reliées à deux corps de joint espacés l'un de l'autre avec un corps de joint au milieu entre eux. Les cordes de courroie reliées aux deux corps de joint espacés l'un de l'autre sont conçues pour traverser l'intérieur du corps de joint positionné au milieu des deux corps de joint auxquels lesdites cordes de courroie sont raccordées.

벨트로프 내장형 텔레스코픽 마스트가 개시된다. 본 발명에 따른 벨트로프 내장형 텔레스코픽 마스트는, 외경이 서로 다른 복수의 마디체와, 마디체들을 동시적으로 작동시키기 위해 마디체들을 연결하는 복수의 벨트로프와, 각 마디체 상단에 결합되며 벨트로프의 이동을 안내하는 가이드 롤러가 일측과 대향부 타측에 매입된 칼라부와, 복수의 마디체 중 직경이 가장 큰 최하단 마디체의 하단에 결합되며 어느 한 벨트로프의 양단이 고정되는 벨트로프 고정자 및 최하단 마디체를 제외한 각 마디체 하단에 결합되며 어느 한 벨트로프의 양단이 고정되고 다른 한 벨트로프가 이동 가능하게 결합되는 벨트로프 안내자를 포함하며, 복수의 마디체는 서로 중첩되게 조립되어 길이가 조절되는 텔레스코픽 구조로 형성되고, 복수의 벨트로프 중 최하단 벨트로프를 제외한 나머지 벨트로프가 중간에 하나의 마디체를 사이에 두고 서로 떨어진 두 개의 마디체에 연결되되, 서로 떨어진 두 개의 마디체에 연결되는 벨트로프가 연결 대상 두 개의 마디체 중간에 위치하는 마디체 내부를 통과하도록 구성되는 것을 요지로 한다.
