Abstract
The utility model relates to a pulley gear, and in particular relates to a pulley gear capable of preventing a cable from breaking away from a groove. The pulley gear capable of preventing the cable from breaking away from the groove comprises a supporting shaft, a pulley yoke, a pulley body, a self-lubricating bearing, a pulley shaft, a shock isolation sleeve and an anti-jump pipe, wherein the upper end of the pulley yoke is connected to the middle part of the supporting shaft, the pulley body is arranged at the middle part of the pulley yoke, the pulley shaft penetrates through the pulley yoke and the pulley body in sequence, the self-lubricating bearing is arranged between the pulley shaft and the pulley body, the anti-jump pipe is arranged at the lower end of the pulley yoke, and the shock isolation sleeve is arranged outside the pulley shaft. The pulley gear capable of preventing the cable from breaking away from the groove also comprises a roller wheel for preventing the cable from breaking away from the groove, wherein the roller wheel for preventing the cable from breaking away from the groove is arranged at a pulley inlet. The pulley gear disclosed by the utility model is simple in design and solves the problem that the cable breaks away from a pulley groove when being subjected to a large external force, the cable is in contact with the roller wheel for preventing the cable from breaking away from the groove, only rolling friction exists, and the cable can be effectively protected at the same time to prevent the cable from being abraded.
Description
Technical field
The utility model relates to pulley gear, is specifically related to the de-groove pulley gear of a kind of anti-hawser.
Background technique
The anti-hawser of pulley or wire rope disengaging at present just arranges the steel pipe that prevents that rope breaks away from the cornerite district, but this kind of device only allows, hawser enters pulley and is no more than 5 ° and uses, but when hawser is subject to larger External Force Acting, the angle that hawser can be offset is larger, even over 5 °, thereby pulley is produced to larger axial force, and hawser may rub on pulley frame, destroy hawser.
Summary of the invention
In order to address the above problem, the utility model proposes the de-groove pulley gear of a kind of anti-hawser, can effectively prevent that hawser from taking off groove, reduce the friction of hawser.
In order to reach the foregoing invention problem, the utility model proposes following scheme:
The de-groove pulley gear of anti-hawser, it comprises back shaft, pulley frame, pulley body, self oiling bearing, pulley spindle, shock insulation cover and anti-jump pipe, the pulley frame upper end is connected in the middle of back shaft, pulley body is contained in the middle of pulley frame, pulley spindle passes successively from pulley frame and pulley body, and between pulley spindle and pulley body, self oiling bearing is housed, anti-jump pipe is equipped with in the pulley frame lower end, the shock insulation cover is equipped with in the pulley spindle outside, the de-groove pulley gear of described anti-hawser also comprises the de-grooved roller of anti-hawser, and the de-grooved roller of anti-hawser is arranged on pulley inlet.
The de-grooved roller of described anti-hawser is divided into transverse-roller and vertical roller, and transverse-roller is installed near pulley, and vertical roller is contained in the transverse-roller outside, and transverse-roller and vertical roller all are loaded on pulley hawser inlet.
The two ends of described back shaft and the two ends of pulley spindle all are installed on support.
Described transverse-roller has two, be divided into transverse-roller and lower transverse-roller, described vertical roller has two, is divided into left vertical roller and right vertical roller, and two transverse-rollers are installed near pulley side by side, two vertical rollers are contained in the transverse-roller outside side by side.
The de-grooved roller of described anti-hawser adopts engineering plastic alloy.Adopt engineering plastic alloy frictional force little, can use the plurality of advantages such as water lubrication.
The utility model has the advantages that simplicity of design, break away from the problem of pulley groove when solving hawser and being subject to larger external force, and hawser contact with the de-grooved roller of anti-hawser, only have rolling friction, the while can effectively be protected hawser, prevents that hawser from wearing and tearing.
The accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is side view of the present utility model.
