Abstract

The invention provides a drum and hoisting equipment. The drum comprises a drum body, drum skin and two baffles, wherein the drum skin is arranged on the periphery of the drum body and is provided with a plurality of parallel rope grooves with the outer diameter matched with that of ropes, and the rope grooves are spirally arranged in the circumferential direction of the drum body; and the two baffles are separately arranged at the two ends of the drum body in the circumferential direction of the ends of the drum body, and an obtuse angle is formed between the side face, towards the drum body,of each baffle and the outer circumferential surface of the drum body. According to the drum provided by the embodiment of the invention, the ropes can be prevented from being out of order, the friction between the ropes and the drum body and the friction between the ropes are reduced, and the service life of the ropes is prolonged.

Description

technical field [0001] The invention relates to the technical field of ropes for cranes, in particular to a reel and lifting equipment. Background technique [0002] Steel wire rope is a general hoisting rope for all kinds of cranes. It has good structural stability, anti-rotation, extrusion resistance, fatigue resistance and multi-layer winding performance, but it also has self-heavy, poor flexibility, easy to wear, easy to corrode, Disadvantages of using tangled rope in multi-layer winding. [0003] High-strength polyethylene fiber is an ideal material for making ropes, especially marine ropes: its specific gravity is low, only 0.97g / cm3, and the ropes made of it can float on water; The fracture length is 8 times that of steel rope and 2 times that of aramid fiber; it has good light resistance and can withstand sunlight for a long time, and the strength retention rate can still reach more than 80% after 1500 hours of sunlight; its chemical stability is good, It is resist...
