Embodiment 1

[0022] see figure 1 — Figure 7 , a high-strength rope wheel, the overall structure of the rope wheel is a forging, including a main shaft 0, a wheel rim 3, a wheel spoke 1, a wheel hub 2, a wheel lining, and a tension wire rope 4, and the main shaft 0 and the wheel hub 2 are installed There are four rows of cylindrical bearings 5, and dust-proof and grease-proof seals 11 are arranged on the end faces on both sides of the bearings; the sheave body is mounted on the fixed bracket 9 through bolts, and there are at least 4 stress-relief holes in the circumferential direction of the spokes. Hole 11 of Ø50mm. The main reason for the cracking of the sheave is that the positional relationship of the three sheaves leads to an eccentric load, which causes the stress at the root of the sheave groove to rise sharply and cause damage. The stress at the dangerous part of the improved sheave decreases significantly, making the sheave have Sufficient strength, the improved sheave works wel...

Embodiment 2

[0024] see Figure 7 , 8 , as an improvement of the present invention, the wheel liner is divided into three structures: the wheel liner 6, the wheel liner 7 and the special-shaped connecting wheel liner 8, and the wheel liner 6, the wheel liner 7 and the special-shaped connecting wheel liner 8 are matched and embedded in the In the wheel groove 12, the middle of the wheel linings 6 and 7 has a split asymmetric structure; the special-shaped connecting wheel lining 8 has a three-splitting structure, and the upper edge arcs of the wheel linings 6, 7, and 8 are in line with the Zhang Tighten the wire rope 4 in direct contact.

Embodiment 3

[0026] As an improvement of the present invention, the transition fillet on the outside of the rim 3 is set to R50mm. Improve its fatigue resistance.

Abstract

The invention relates to a high-strength rope wheel. The rope wheel is characterized in that the integral structure of the rope wheel is made of a forging; the rope wheel comprises a main shaft, a wheel edge, a wheel spoke, a wheel hub, wheel linings and a tension steel wire rope, wherein four lines of cylindrical bearings are arranged between the main shaft and the wheel hub, the end surfaces of two sides of each bearing are respectively provided with a dustproof and grease leakage-preventing seal, a rope wheel body is arranged on a fixing bracket by bolts, and the periphery of the wheel spoke is provided with at least four phi 50mm holes for relieving stress. Compared with the traditional rope wheel, the high-strength rope wheel and a rope wheel lining replacement method have the beneficial effects that (1) the strength of the wheel edge of the rope wheel is greatly improved; (2) the service life of the wheel lining is greatly prolonged; (3) as the circular arc surface of the inside surface of each wheel lining is embedded in a wheel groove, the slippage between the corresponding wheel lining and the corresponding wheel groove is avoided, the abrasion of the steel wire rope and the corresponding wheel lining is little, and the easiness in damage of the rope wheel is avoided; (4) the detachment and installation of each wheel lining are simple and convenient.

Description

technical field [0001] The patent relates to a cold-rolled high-strength horizontal looper sheave and an improved sheave liner replacement method. Background technique [0002] In order to ensure continuous production, modern metallurgical cold-rolling and steel-rolling enterprises all adopt looper devices. The cold-rolled pickling-continuous rolling unit of Meishan Iron and Steel Co., Ltd. is also equipped with 3 horizontal loopers. When the scissors are changed and the rolls of the rolling mill are changed, other equipment can continue to produce normally. The forms of the three loopers are the same, and the difference is only in the storage volume of the strip steel. The wire rope traction system of the looper trolley is driven by a motor with three sheaves. The sheaves drive the wire rope to move through friction, and finally drive the looper trolley to move on the track. One end of the wire rope is fixed, and the other end is connected to the hydraulic cylinder to prov...
