Multilayer broken line rope groove winding drum

Abstract

The invention discloses a multilayer broken line rope groove winding drum with more than four rope climbing tables for lifting equipment. The multilayer broken line rope groove winding drum comprises a drum, flange plates and rope climbing tables above a fourth layer, the flange plates are arranged on two sides of the drum, rope grooves in the drum are broken line rope grooves formed by staggering two parallel portions and two crossing portions, rope climbing tables below a third layer are arranged at the joints of the drum and the flange plates, and rope shifting tables are arranged on the inner sides of the flange plates on the two sides of the drum. The rope climbing tables above the fourth layer are positioned on side wall boards of the flange plates of the drum and are arc-shaped projections on the wall boards of the flange plates, and the rope climbing tables above the fourth layer and the rope shifting tables are separately positioned in sector regions corresponding to the rope grooves of the two crossing portions. The number of the rope climbing tables above the fourth layer can be set as needed according to the number of steel wire ropes needing to be controlled not to be disordered in winding, the problem of disorder of ropes arranged by a plurality of drums with high rope capacity can be solved, and the service lives of the steel wire ropes are prolonged.

Description

1. Technical field [0001] The invention relates to a reel used for hoisting equipment, in particular to a reel wound with multi-layer steel wire ropes of broken line grooves. 2. Background technology [0002] With the increase of large-scale equipment and super-high buildings, high-lift hoisting equipment has been widely used, which requires the hoisting hoisting device to have a longer steel wire rope and a drum with a large rope capacity. The multi-layer wire rope winding reels used in existing cranes and other lifting equipment mostly use broken line grooved drums. The current broken line rope grooved drums have two sections of broken line rope grooves and two sections of straight lines within the circumference of the drum. The rope groove, and the straight rope groove (parallel part) and the broken line rope groove (intersection part) are arranged alternately, which are generally called double broken line rope grooves. When the wire rope is wound along the circumferenti...

Problems solved by technology

[0003] The object of the present invention is to provide a multi-layer winding reel with broken line rope grooves, which uses more than four layers of rope climbing platforms to control the arrangement of the wire ropes so that the wire ropes are not disordered, so as to solve the problem of disordered wire ropes in the multi-layer winding wire rope reel.
