Abstract

The utility model discloses a kind of universal guide rope device, comprise and be separately installed with two upper rollers and two lower rollers according to two-layer up and down in the holder, and " well " font that projects into of two upper rollers and two lower rollers arranges; The two ends of each upper roller and each lower roller are all sleeved in a bolt shaft by antifriction-bearing box, and one end of each bolt shaft is supported in the mounting hole of bearing by axle sleeve; Meanwhile, the other end of bolt shaft has oil hole along axle center, and oil hole inwardly leads to the antifriction-bearing box at two ends through radial hole, oil hole external port is provided with zerk.Device of the present utility model, the steel rope of any direction bending well can be subject to the constraint of four rollers, and steadily, upper roller and lower roller turn flexibly, do not exist the sideslip card rope of steel rope, reduce the wearing and tearing of steel rope guiding.

Description

Universal guide rope device

Technical field

The utility model belongs to technical field of petroleum machinery, relates to a kind of universal guide rope device.

Background technology

In offshore oil drilling operation process, on drilling floor surface, the handling of various instrument and drilling rod normally drives steel rope to be realized by the auxiliary pulley guiding on overhead traveling crane by air hoist, but by derrick inner space and rig floor layout restrictions, steel rope air hoist leading to auxiliary pulley often interferes with derrick, thus just needs on derrick, to arrange guide rope device avoid interference.Existing guide rope device is single roller structure, can only play directional tagging in one direction, can not meet the guiding demand of air hoist cylinder rope stretching back and forth, make steel rope easily occur sideslip card rope phenomenon.

Utility model content

The purpose of this utility model provides a kind of universal guide rope device, solves prior art guide rope device and there is steel rope sideslip card rope, causes the problem of steel rope abrasion quickening, the lost of life.

The technical scheme that the utility model adopts is, a kind of universal guide rope device, comprises and is separately installed with two upper rollers and two lower rollers according to two-layer up and down in the holder, and " well " font that projects into of two upper rollers and two lower rollers arranges.

Universal guide rope device of the present utility model, is further characterized in that:

The two ends of each upper roller and lower roller are all sleeved in a bolt shaft by antifriction-bearing box, and one end of each bolt shaft is supported in the mounting hole of bearing by axle sleeve; Meanwhile, the other end of bolt shaft has oil hole along axle center, and oil hole inwardly leads to the antifriction-bearing box at two ends through radial hole, oil hole external port is provided with zerk.

The riser of bearing side has four through holes.

The beneficial effects of the utility model are, two upper rollers become " well " word arrangement with two lower rollers, and antifriction-bearing box is all installed in upper roller and lower roller two ends, is fixed on bearing by bolt shaft, axle sleeve by roller; Bearing is arranged on derrick by bolt, steel rope is through the auxiliary pulley led to afterwards overhead traveling crane in the middle of " well " word roller, and " well " word boring ratio wirerope diameter is bigger, thus retrains by surrounding roller when steel rope is led, bolt spindle nose is provided with zerk simultaneously, can make bearing sufficient lubrication, roller turn is flexible, effectively reduces guiding friction force, the guiding that steel rope is gone up in any direction can be realized, steel rope is led steadily do not rock, structure is simple, easy for installation.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the utility model structure is, is included in bearing 1 and is separately installed with two upper rollers 2 and two lower rollers 3 according to two-layer up and down, and " well " font that projects into of two upper rollers 2 and two lower rollers 3 arranges;

The two ends of each upper roller 2 and lower roller 3 are all sleeved in a bolt shaft 4 by antifriction-bearing box 5, and one end of each bolt shaft 4 is supported on by axle sleeve 6 in the mounting hole of bearing 1, and this termination is provided with the nut of band safety plug; Simultaneously, the other end (positive stop end) of bolt shaft 4 has oil hole along axle center, and oil hole inwardly leads to the antifriction-bearing box 5 at two ends through radial hole, oil hole external port is provided with zerk 7, make antifriction-bearing box 5 to obtain sufficient lubrication, each upper roller 2 and lower roller 3 all rotate flexibly.

With reference to Fig. 3, the riser of bearing 1 side has four through holes 10, the rigging position abutting joint on bearing 1 with derrick.

With reference to Fig. 5, Fig. 6, Fig. 7, the utility model using method is, entirety adopts bolt to be fixedly attached on derrick beam by four through holes 10 of bearing 1, by the middle auxiliary pulley through leading to afterwards overhead traveling crane of " well " word that steel rope 8 is formed from two upper rollers 2 and two lower rollers 3, finally guide in air hoist 9, " well " word intermediate space distance is slightly larger than the diameter of steel rope 8, so that the steel rope 8 of any direction bending well can be subject to the constraint of four rollers, guiding steadily, upper roller 2 and lower roller 3 rotate flexibly, there is not the sideslip card rope of steel rope, reduce the wearing and tearing of steel rope.
