Abstract
The invention discloses an installing and positioning method of a drum rope climbing block, and belongs to the field of crane accessories. The method includes the steps that the expanded view of a drum is drawn; the intersection point of a rope groove line and a side plate is used as the 0-degree position, and the 0-degree position is adjusted to be the midpoint of the circumferential-direction expansion line of the drum in the expanded view of the drum, wherein two axial expansion lines in the expanded view of the drum are the positions of a 180-degree angle; the installation position of the rope climbing block is determined; the positioning angle of the rope climbing block is calculated to be L3 / L2x360 degrees; the 0-degree position of the drum is drawn on the drum; the 180-degree angle is measured in the circumferential direction of the drum according to the drawn 0-degree position of the drum, and the position of the 180-degree angle of the drum is drawn; the installation position of a first bottom face is drawn; and the rope climbing block is installed on the drum according to the position of the first bottom face of the rope climbing block. The method is simple, accurate, rapid and easy to implement, the installation precision of the rope climbing block can be ensured, and efficiency of workers is improved.
Description
technical field [0001] The invention relates to the field of crane accessories, in particular to a method for installing and positioning reel climbing rope blocks. Background technique [0002] With the in-depth development of construction machinery technology, human activities have increasingly strong demand for cranes with large lifting heights. The hoisting height of the crane directly affects the rope capacity of the hoisting mechanism, and the rope capacity of the drum of the crane directly restricts the hoisting height of the crane. In order to achieve the purpose of increasing the lifting height of the crane without increasing the weight and overall size of the crane, the crane generally adopts a double-layer winding drum. The rope block achieves double-layer winding. A key issue of the double-layer winding reel is the installation and positioning of the climbing rope block. The more accurate the positioning of the climbing rope block on the double-layer winding ree...
