3 Terms and definitions
The following terms and definitions as defined in GB/T 3893-2008 apply to this document.
3.1
Wire rope declination ropefleetangle
The maximum angle at which the wire rope enters the reel or pulley (first rope pulley), that is, when the wire rope moves to the left or right side of the reel
The maximum angle between the centerline of the wire rope and the plane perpendicular to the reel or pulley axis, as shown in Figure 1, δ1 and δ2.
Figure 1 Schematic diagram of wire rope deflection
4 reel type
According to the surface rope groove form, the wire rope reel can be divided into three types. a light reel, a spiral groove reel and a polyline rope reel.
a) Optical reel. a cordless groove arrangement on the surface of the reel;
b) spiral grooved reel. the surface of the reel is machined with a spiral groove;
c) Broken rope groove. The surface of the drum is machined with a folding rope groove, and the folding rope groove is divided into a single-fold rope groove and a double-fold rope groove.
reel.
According to the installation method of the end of the wire rope, the wire rope reel can be divided into two types. single reel and double reel.
