Lifting workbench for mounting bridge stay cable
The invention discloses a lifting workbench for bridge stay cable installation, and relates to the technical field of lifting protection equipment, the lifting workbench comprises a brake assembly, a lifting table and a vertical guide rail, a first rotating wheel set is coaxially integrated with a drum brake structure, and the first rotating wheel set is composed of a first abutting wheel and a hollow second abutting wheel; the first abutting wheel and the fixed cylinder are arranged into a whole through a threaded rod, a sliding sleeve is axially arranged on the threaded rod in a sliding mode, the threaded rod is in threaded connection with the second abutting wheel, the opposite faces of the fixed cylinder and the sliding sleeve are inclined, and a brake block is arranged between the fixed cylinder and the sliding sleeve. The lifting platform has the technical advantages that relative rotation is generated between the first abutting wheel and the second abutting wheel through the drum brake structure during stall, and then the brake block is pushed out and abuts against the second abutting face to complete braking of the lifting platform; through linkage between the drum brake structure and the turning plate piece, the lifting table still slides downwards after the sliding base is braked, so that the wheel body abuts against the side groove to generate secondary braking on the lifting table.
本申请公开了一种桥梁斜拉索安装用升降工作台，涉及升降保护设备技术领域，包括刹停组件、升降台和竖向导轨，第一转动轮组同轴集成有鼓刹结构，第一转动轮组由第一抵接轮和空心状的第二抵接轮组成，第一抵接轮通过螺纹杆与固定筒设于一体，螺纹杆上轴向滑动设有滑动套筒，且螺纹杆丝接于第二抵接轮，固定筒与滑动套筒的对立面设置为倾斜状，且两者之间设有刹停块，本申请的技术优势是：面对失速时通过鼓刹结构使得第一抵接轮与第二抵接轮之间产生相对转动，进而刹停块被推出并抵接于第二抵接面完成对升降台的刹停；通过鼓刹结构与翻板件之间的联动，滑动基座刹停后升降台仍然向下滑动，使得轮体抵接于侧部凹槽产生对升降台的二次刹停。
