Description

Technical Field

[0001] This utility model relates to the technical field of freight elevators, specifically to a rope-stopping protection device for the bottom wheel of a machine-room-less freight elevator. Background Technology

[0002] Machine room-less freight elevators are a type of modern freight elevator. Their main feature is that the electrical control system and mechanical equipment are all installed inside the elevator shaft, eliminating the need for a separate machine room. This design gives machine room-less freight elevators significant advantages in terms of space utilization, energy conservation, environmental protection, and operation and maintenance costs. Because they do not require a separate machine room, machine room-less freight elevators save building space and are particularly suitable for space-constrained locations. They are a highly efficient, energy-saving, and safe freight transport device applicable to various situations, significantly improving the efficiency and safety of freight transport.

[0003] Traditional rope protection in machine-room-less freight elevators uses a fixed rope guard plate structure. However, the rope guard plate and the wire rope experience sliding friction. When the wire rope wobbles and contacts the guard plate, it generates severe friction, continuously abrading the rope surface like a file, shortening its service life. Furthermore, when the force of the wire rope jumping out of the groove is large, it may bump or bounce on the guard plate, and there is still a risk of failure at certain extreme angles. The friction and impact between the wire rope and the fixed guard plate generate continuous hissing or clicking metallic friction noise, which has a certain adverse effect on people's use. To address this, we propose a rope protection device for the bottom wheel of a machine-room-less freight elevator. Utility Model Content

[0004] Technical Problem Solved: Addressing the shortcomings of existing technologies, this utility model provides a machine room-less freight elevator bottom wheel rope-stopping protection device, which has advantages such as reduced wear, extended service life, and reduced safety hazards. The moving frame is sleeved on both sides of the outer wall of the opposing adjusting rod through a through-threaded hole, positioning the rolling guide rollers on both sides of the inner wall of the wire rope penetration opening. The central dividing block acts as a separator on the inner wall of the opposing adjusting groove. The control motor drives the central rotating rod to rotate the central rotating gear. Through the action of the linkage chain, the adjusting control gear and the side rotating rod can be rotated. When the side rotating rod rotates, it can drive the opposing adjusting rod to rotate on the inner wall of the opposing adjusting groove, causing the moving frame to move in opposite directions on the outer wall of the opposing adjusting rod. Simultaneously, it drives the rolling guide rollers to move in opposite directions on the inner side of the wire rope penetration opening. The rolling guide rollers and the wire rope experience rolling friction. When the wire rope wobbles and contacts the rolling guide roller, it drives the rolling guide roller to rotate. The rolling guide roller can move on the outer wall of the limit connecting rod through the action of the bearing, transforming harmful sliding friction into efficient rolling friction. This reduces wear, significantly extends the service life of the wire rope, and lowers replacement costs and safety hazards. Moreover, the opposing rolling guide rollers can actively meet the wobbling wire rope. The guide grooves of the two rolling guide rollers can more gently and smoothly clamp the rope and guide it back to the correct rope groove position. This dynamic and flexible clamping action is more reliable and efficient than a fixed wall. When the wire rope is in the guide groove of the rolling guide roller, the rolling friction is almost noiseless. Eliminating this major noise source makes the elevator operation quieter, improves the overall quality of the elevator and the user experience, and can effectively solve the problems in the background technology.

[0024] Working Principle: A machine room-less freight elevator bottom wheel rope protection device, in use, the main protective cover 1 is connected and positioned by the connecting base 2, the movable frame 19 is sleeved on both sides of the outer wall of the opposing adjusting rod 9 through the through threaded hole 20, so that the rolling guide roller 23 is positioned on both sides of the inner wall of the wire rope through-hole 4, the central dividing block 8 acts as a separator on the inner wall of the opposing adjusting groove 7, the control motor 10 drives the central rotating rod 11 to drive the central rotating gear 12 to rotate, and through the action of the linkage chain 15, it can drive the adjusting control gear 14 and the side rotating rod 13 to rotate.

The guide grooves of the two rolling guide rollers 23 can more gently and smoothly clamp the rope and guide it back to the correct groove position. This dynamic and flexible clamping action is more reliable and efficient than a fixed wall. When the wire rope is within the guide groove of the rolling guide roller 23, the rolling friction is almost noiseless, eliminating this major noise source and making the elevator quieter, thus improving the overall quality and user experience.
