2.5-circle fixed screw position equal circumference winding friction winch wheel

Abstract

The invention discloses a 2.5-circle fixed screw position equal circumference winding friction winch drum. The 2.5-circle fixed screw position equal circumference winding friction winch drum is characterized in that the surface of a circular drum (1) is circumferentially recessed to form a spiral semi-circular rope groove (2), and a steel wire rope (3) is clamped in the rope groove (2) in a winding mode. According to the 2.5-circle fixed screw position equal circumference winding friction winch drum, the rope enters and exits in a fixed screw position mode, no phenomenon of steel wire rope returning forced by extrusion caused by discharging and winding the rope at one end of a shaft exists, winding of each circle of the rope is equal circumference winding, no instantaneous detachment rotating loss phenomenon of the rope and the drum exists, and the rope speed is uniform.

Description

technical field [0001] The invention relates to the technical field of winches, in particular to a 2.5-circumference fixed screw position and equal circumference winding friction winch drum. Background technique [0002] Multi-rope friction hoist is one of the important equipment in mines, and it is the main means of transportation connecting the underground and the ground. equipment. In the prior art, the multi-rope friction hoisting winch puts a plurality of steel wire ropes on the friction lining of the capstan, and the hoisting container is suspended on both ends of the steel wire ropes, and a balance tail rope is suspended on the bottom of the container. When the hoist is working, the pulling The tight steel wire rope must be pressed against the friction lining with a certain positive pressure. When the capstan is driven by the motor to rotate in a certain direction through the reducer, a large friction force will be generated between the steel wire rope and the fricti...

Problems solved by technology

During this process, the oblique extrusion of the steel wire rope to the small diameter, the drawstring locking of the loose coils of the steel wire rope, etc., cause the rope bite of the steel wire rope, the sliding friction between the ropes, the sliding friction between the rope and the drum, and the moment when the rope and the drum are separated. The loss of rotation will cause unstable movement, severe sharp friction and sparks, etc. Therefore, its application is greatly restricted in the presence of flammable and explosive substances and in occasions with strict requirements for motion accuracy.
