The invention relates to a lifting appliance, in particular to a lifting appliance for a wide strip steel coil. The lifting appliance comprises an upper cross beam, a vertical beam and a lower cross beam, a lifting stop block is arranged on the upper portion of the outer end of the lower cross beam, and a first guide rod and a first transmission rod on the inner side of the first guide rod are fixedly connected to the bottom of the lifting stop block and inserted into a first guide hole of the lower cross beam. A transmission plate is arranged above the lower cross beam on the inner side of the lifting stop block, a second transmission rod and a second guide rod are fixedly connected to the bottom of the transmission plate and inserted into a second guide hole of the lower cross beam, and the second transmission rod is adjacent to the first transmission rod; a first rack and a second rack are mounted on the opposite sides of the first transmission rod and the second transmission rod below the lower cross beam respectively, a gear meshed with the two racks is arranged between the first rack and the second rack, and the gear is rotationally connected with the lower cross beam; and in a to-be-hoisted state, the top surface of the lifting stop block is flush with the top surface of the transmission plate. A lifting worker can conveniently observe the position of the lifting appliance, the lifting efficiency is improved, and the safety is improved during lifting.
本发明涉及吊具,特别是一种用于宽带钢卷的吊具。吊具包括上横梁、竖梁和下横梁,所述下横梁外端的上部设有升降挡块,第一导向杆和其内侧的第一传动杆固接于升降挡块的底部并插装在下横梁的第一导向孔内;所述升降挡块内侧的下横梁的上方设有传动板,第二传动杆和第二导向杆固接于传动板的底部并插装在下横梁的第二导向孔内,第二传动杆紧邻第一传动杆;所述下横梁下方的第一传动杆和第二传动杆的相对侧分别安装第一齿条和第二齿条,第一齿条和第二齿条之间设置与两个齿条啮合的齿轮,齿轮置与下横梁转动连接;待吊装状态下,升降挡块的顶面与传动板的顶面平齐。本发明便于起重工观测吊具的位置,提高吊装效率,吊装时提高安全性。
