Description
Technical Field
The utility model relates to a lifting means's rope sheave guider.
Background
The rope pulley block part of the lifting equipment in the prior art is complex in structure, the machining of the rope pulley block part inevitably causes tolerance out-of-tolerance or deviation, at least one or more ropes of the passenger-carrying lifting equipment are worn in use according to the specification of the lifting equipment to influence the service life of the ropes and the wheels, or a bearing is damaged in advance, the maintenance cost of the machining and lifting equipment is higher, and the quality is difficult to control.
The existing rope pulley of the hoisting equipment is a pulley with two parallel deep groove ball bearings on two sides, only bears radial load, and has the defect that the service life of the pulley and the rope is shortened sharply when the rope tension is uneven. Meanwhile, the bearing has swinging after the height is increased, and the service life of the bearing is also influenced. The invention adopts the guide bearing wheel corresponding to the rope, and the guide bearing wheel adopts the double-row angular contact bearing, which has the advantages of radial load force and bidirectional axial load force; when the lifting device is in operation, the bearing wheels are not damaged if the load force is biased or there is a swing. The prior structure is a deep groove ball bearing on two sides, the bearing can only bear radial load, and the load of axial load force can not appear, and if the axial load force exists, the service life of the bearing can be reduced; when the rope tension is uneven, especially when the tension on both sides is uneven, the life of the pulley and the rope is shortened rapidly. The bearing rope wheel is integrated, the abrasion of the paired wheel and the rope is reduced, and the service life of the bearing is prolonged.
Disclosure of Invention
The utility model discloses bearing rope sheave purpose all is the life-span of extension rope and wheel and bearing, accomplishes the guide effect simultaneously.
Be suitable for lifting equipment's rope sheave guider, its characterized in that:
each rope corresponds to a guide bearing rope wheel, and the guide bearing rope wheel adopts a double-row angular contact bearing (or a double-row self-aligning roller bearing or a double-row cylindrical roller bearing, wherein the mode of the double-row angular contact bearing is related to the load capacity of lifting equipment).
The hoisting device typically has one or more ropes, the number of which is related to the load capacity of the hoisting device and the rope load capacity.
The ropes used in the hoisting device include not only: various round ropes such as steel wire ropes, rubber-coated steel wire ropes, fiber ropes, resin ropes, and the like.
Be suitable for lifting means's bearing rope sheave device, including inner circle, outer lane, rolling element, grease, holder and sealing washer, its characterized in that: the guide bearing rope wheel adopts a double-row angular contact bearing; the middle part of the outer diameter surface of the outer ring is provided with rope grooves, the number of the grooves corresponds to the number of ropes, and the types of the rope grooves are generally semicircular U-shaped grooves or semicircular U-shaped grooves with notches, and can also be V-shaped grooves; because the double-sealing long-acting heavy-load grease is adopted, the lubrication and maintenance-free can be achieved.
The structure of the utility model can reduce the wear of the rope, prolong the service life of the wheel and the bearing, and simultaneously complete the guiding function (also called a pulley or a reverse rope pulley)
The past products are that two bearings are arranged on one wheel; the invention has no independent wheel and two bearings, integrates the wheel and the bearings into a bearing wheel, only one shaft is assembled when the bearing wheel is used, and the bearing wheel can be used on site, so the structure is simplified.

Detailed Description
Be suitable for lifting equipment's rope sheave guider, its characterized in that:
the rope corresponds to a guide bearing rope pulley set, and a guide bearing rope pulley of the guide bearing rope pulley adopts a double-row angular contact bearing (or a double-row self-aligning roller bearing or a double-row cylindrical roller bearing, and the mode of the double-row angular contact bearing or the double-row cylindrical roller bearing is related to the load capacity of lifting equipment).
The number of grooves of the guide bearing wheel corresponds to the number of ropes. The hoisting device typically has one or more ropes, the number of which is related to the load capacity of the hoisting device and the rope load capacity.
The semi-circular U-shaped groove double-row angular contact sealed bearing wheel (also can be made into a semi-circular U-shaped double-row deep groove ball bearing wheel or a double-row self-aligning roller bearing wheel or a double-row cylindrical bearing wheel) is suitable for one rope or a plurality of ropes.
The guide device has the characteristics of reducing the abrasion of the rope, prolonging the service life of the wheel and the bearing and simultaneously completing the guide function.
The notched semi-circular U-shaped groove double-row angular contact sealed bearing wheel (which can also be made into a notched semi-circular U-shaped groove double-row deep groove ball bearing wheel or a double-row self-aligning roller bearing wheel or a double-row cylindrical bearing wheel) is suitable for one rope or a plurality of ropes.
The guide device has the characteristics of reducing the abrasion of the rope, prolonging the service life of the wheel and the bearing and simultaneously completing the guide function.
The V-shaped groove double-row angular contact sealed bearing wheel (which can also be made into a V-shaped groove double-row deep groove ball bearing wheel or a double-row self-aligning roller bearing wheel or a double-row cylindrical bearing wheel) is suitable for one rope or a plurality of ropes.
The guide device has the characteristics of reducing the abrasion of the rope, prolonging the service life of the wheel and the bearing and simultaneously completing the guide function.
When the rope runs on the bearing rope pulley group, the self-correcting function is realized, the deviation is prevented, the damage of the rope is prevented, and the service life of the rope can be prolonged;
