Hoist Parts Lbs Winch Rope Drum With Nylon Polymer Or Steel Sleeves

LBS drum is a kind of groove form suitable for multi-layer winding of wire rope introduced from abroad. Because this kind of rope groove is kept parallel with the flange end face in most sections of the drum circumferential direction, and only intersects with the flange end face in a very small section, the rope groove must be turned, hence the name "folding rope groove".

Years of practical use show that this kind of special rope groove structure of the drum, can well solve the problem of wire rope multi-layer winding rope about double folded cord slot system, to ensure that the multilayer on the drum winding rope fully involved in and roll out the reel smoothly, and can greatly prolong the service life of wire rope, the system is still the most effective method and the most perfect. Tests have shown that the Lebus drum can prolong the life of the wire rope by more than 500% with the rope groove matching the specifications of the wire rope.

the use of environment:

1. Outdoor use is allowed;

2. The altitude does not exceed 2000M;

3. Ambient temperature -30℃ ~ +65℃;

4. It is allowed to work under rain, splash and dust conditions.

This LBS reel model is: LBSZ1080-1300

Represents the diameter of the Ribas drum is 1080mm, the length is 1300mm,

Provide wire rope laying service, in the site with the ship winch wire rope chain connection or drilling rig, crane link cable laying operation, to better protect the wire rope.

Winch drum is an important part of oil rig winch, winch drum

One end of the wound wire rope is fixed at the drum rope socket through a rope clip, and the other end

The guide wheel of the sky car is introduced into the trolley pulley group, and the trolley pulley group is installed

Equipped with hooks, faucets and drill pipe strings. When the winch works, it is wound

The steel wire rope on the drum realizes the action of winding and releasing the rope through positive and negative rotation of the drum

The drum bears the fast rope tension of the wire rope, and the drum structure must meet the strength

Outside, but also to ensure that the wire rope winding neatly.

With the development of oil drilling winches in recent decades, winches appear more

The transmission form and the structure form, but the winding rope rule of the winch drum is not change, our company developed LEBUS rope groove has obvious advantages. LEBUS rope groove double line form, suitable for multi-layer winding, can effectively reduce or avoid steel wire Rope disorder phenomenon. In the design process of the drawworks drum, the drawworks drum has a large opening range Small, bottom diameter selection, position of guide block, rope socket structure, rope groove spacing, rope groove the spiral Angle of the parallel section and the climbing section will affect the effect of drum rope winding, becauset this, the study of winch drum structure and characteristics, will help to reduce or avoid oil field field hoist drum disorderly rope phenomenon, prolong the use of wire rope and drum life.

Features: LBS double fold rope grooves are composed of straight rope grooves and diagonal rope grooves for each round of the drum, and the position of the straight rope grooves and diagonal rope grooves for each round is exactly the same. When the wire rope is wound in multiple layers, the position of the crossing transition point between the upper wire rope and the lower wire rope is fixed through the diagonal rope groove, so that the crossing of the upper wire rope is completed in the diagonal section. In the straight rope groove segment, the upper wire rope completely falls into the groove formed by two lower wire ropes, forming line contact between the ropes, so that the contact between the upper and lower wire ropes is stable. When the rope is returned, the step retaining ring with return flange at both ends of the drum is used to guide the rope to climb up and return smoothly, avoid the disorderly rope caused by the rope cutting and squeezing each other, so that the rope is arranged neatly and smoothly transition to the upper layer, and realize multi-layer winding.

Advantages: LBS folding rope groove, solve the rope in the process of winding rope disorderly rope, rope biting major problems. The folding rope groove makes the wire rope winding smooth, the load evenly distributed between the layers, this technology greatly extends the service life of the wire rope, can prolong the life of the wire rope more than 500%, reduce the damage of the wire rope, improve the safety of equipment operation, and reduce the mechanical equipment for rope replacement stop problem.

When the split type drum fence skin is installed, the split fence skin sleeve is wrapped on the smooth slotless drum, and is closely connected with the drum through bolts or welding, so that the original smooth surface of the drum outside the surface becomes the form of lebus double folding rope groove, which is convenient for the application of winch modification or replacement of the drum.

LBS rope groove drum also requires certain operating conditions. The most important of these conditions is the deflection Angle of the wire rope, which is the Angle between the wire rope from the reel to the first fixed pulley. Generally speaking, this deflection Angle should not be greater than 1.5° and should not be less than 0.5°. There are some slight differences (about a 0.25° variation), but it is good to remember this general statistic. The optimal deflection Angle also depends on the load, cable structure and lifting speed. This deflection Angle indicates that for every 10m from the drum to the pulley, the distance between the wire rope and the midpoint of the drum should not be greater than 260mm (520mm between the two flanges). 9 Q2 ` 2 L! For LBS groove reels, if the deflection Angle exceeds the recommended range, a special rope called Angle compensator can be used to relax and be damaged by extruding or twisting of the outer wire rope onto the groove
