Title (EN) NOVEL LIFTING CLAMP
(FR) NOUVELLE PINCE DE LEVAGE
(ZH) 一种新型吊钳
Abstract:
(EN) A novel lifting clamp, comprising a first clamping plate (1) and a second clamping pate (2) which are overlapped. The first clamping plate (1) and the second clamping plate (2) are each provided with an overlapping area for mutual overlapping; the first clamping plate (1) and the second clamping plate (2) are detachably connected by means of connecting members (4, 5) at the overlapping areas; the connecting members (4, 5) are located at one side of the overlapping areas close to the first clamping plate (1); there are at least two connecting members (4, 5); the at least two connecting members (4, 5) are together connected to the first clamping plate (1) and the second clamping plate (2). The first clamping plate (1) and the second clamping plate (2) in the lifting clamp are connected by means of the connecting members (4, 5) at the same side, and after lifting, the second clamping plate (2) per se is fully stressed since no connecting member is provided at the other side; moreover, the side provided with the connecting members (4, 5) is fixedly connected by means of at least two connecting members (4, 5). Compared with traditionally designed lifting clamps, two connecting members (4, 5) now share the force originally stressed on one connecting member, such that the force applied on the connecting members (4, 5) is reduced, and the coefficient of safety in transport by a crane is increased.
(FR) L'invention concerne une nouvelle pince de levage, comprenant une première plaque de serrage (1) et une seconde plaque de serrage (2) qui se chevauchent. La première plaque de serrage (1) et la seconde plaque de serrage (2) sont chacune pourvues d'une zone de chevauchement pour un chevauchement mutuel ; la première plaque de serrage (1) et la seconde plaque de serrage (2) sont reliées de façon amovible au moyen d'éléments de liaison (4, 5) au niveau des zones de chevauchement ; les éléments de liaison (4, 5) sont situés sur un côté des zones de chevauchement proches de la première plaque de serrage (1) ; il y a au moins deux éléments de liaison (4, 5) ; les deux éléments de liaison minimum (4, 5) sont reliés ensemble à la première plaque de serrage (1) et à la seconde plaque de serrage (2). La première plaque de serrage (1) et la seconde plaque de serrage (2) dans la pince de levage sont reliées au moyen des éléments de liaison (4, 5) sur le même côté, et après levage, la seconde plaque de serrage(2) en elle-même est entièrement contrainte étant donné qu'aucun élément de liaison n'est prévu de l'autre côté ; en outre, le côté pourvu des éléments de liaison (4, 5) est relié de manière fixe au moyen d'au moins deux éléments de liaison (4, 5). Par rapport aux pinces de levage conçues de manière classique, deux éléments de liaison (4, 5) partagent maintenant la force appliquée à l'origine sur un élément de liaison, de telle sorte que la force appliquée sur les éléments de liaison (4, 5) est réduite, et le coefficient de sécurité lors du transport par une grue est augmenté.
(ZH) 一种新型吊钳,包括部分重叠的第一卡板(1)以及第二卡板(2),第一卡板(1)与第二卡板(2)具有相互重叠的重叠区域,于重叠区域第一卡板(1)与第二卡板(2)通过连接件(4、5)进行可拆卸连接,连接件(4、5)位于重叠区域靠近第一卡板(1)的一侧,连接件(4、5)为至少两个,至少两个连接件(4、5)共同连接第一卡板(1)与第二卡板(2)。吊钳中的第一卡板(1)与第二卡板(2)通过位于一侧的连接件(4、5)进行连接,起吊后另一侧由于无连接件,由第二卡板(2)本身完全受力;而设置有连接件(4、5)的一侧通过至少两个连接件(4、5)进行固定连接,与传统设计的吊钳相比较,原来由一个连接件承受的力现在由两个连接件(4、5)来承担,能够减少连接件(4、5)的受力,吊运安全系数增大。
