Abstract

A winch rope guider of a well drilling rope comprises a pulley yoke assembly and rope blocking wheels, wherein a vertical shaft of the pulley yoke assembly is installed between two horizontal shafts of the pulley yoke assembly through shaft sleeves on two ends of the vertical shaft, and an axial guiding groove is arranged in the vertical shaft. Each rope blocking wheel is composed of a pulley, an antifriction bearing, a sliding copper bush, a guiding key, a left cover plate and a right cover plate, wherein the pulley is installed on the sliding copper bush through the antifriction bearing, the guiding key is fixed in the sliding copper bush through a bolt, and the antifriction bearing is fixed in the pulley by the left cover plate and the right cover plate through a bolt. The well drilling rope can slide in a round space formed by two rope blocking wheels arranged side by side, the radial rotation of the rope blocking wheels is achieved through the antifriction bearing installed in the pulley, and the axial slide of the rope blocking wheels in the guiding groove in the vertical shaft is achieved through the guiding key on the sliding copper bush. The abrasion of the sliding copper bush and the vertical shaft is reduced due to the rotation of the antifriction bearing, so the service life of the rope guider is prolonged.

Description

The large rope Winch rope arranger of a kind of drilling well
Technical field:
The utility model relates to oil-well rig with the rope guide of the large rope of drilling well, can be applicable to petroleum drilling machine winch, exploration drill winch and other big or middle winch rope-discharging technical field.
Background technology:
The large rope rope winding jib of the drilling well of using in the prior art, comprise that pulley yoke assembly, back-moving spring, open auger are buckled, pulley set assembly, steel rope, U-shaped attachment bolt form, be installed on one section back of the body fan steelframe of derrick or the upset Shears, the high-order installation affects safe in operation; The other types rope winding jib has by structures such as gearbox drive, motor-driven, chain gears, and its complex structure is bulky and fragile; Pulley and the copper sheathing of some Winch rope arranger gear rope sheaves are structure as a whole, rely on copper sheathing in the gear rope sheave to endwisely slip and radial rotating is realized effective arrangement of the large rope of drilling well at the longitudinal axis of pulley yoke assembly, in the use procedure, be in for a long time the situation of high-speed operation between copper sheathing in the gear rope sheave and the longitudinal axis, so the copper sheathing quick abrasion needs often to change, if the excessive clearance between copper sheathing and the longitudinal axis, rope sheave be can cause keeping off and card, the large rope of severe wear drilling well met.
Summary of the invention:
Technical problem to be solved in the utility model is for the situation that is in for a long time high-speed operation between the copper sheathing in the gear rope sheave in the above-mentioned prior art and the longitudinal axis, copper sheathing quick abrasion, short defective of life-span, provide a kind of and can with orderly being arranged on the winch of the large rope of drilling well, satisfy the large rope Winch rope arranger of a kind of drilling well that oil-well rig uses.
The utility model is comprised of pulley yoke assembly, gear rope sheave, and the longitudinal axis of pulley yoke assembly is installed between the transverse axis of pulley yoke assembly by the axle sleeve at its two ends, has axially directed groove at the longitudinal axis; The gear rope sheave is comprised of pulley, antifriction-bearing box, slip copper sheathing, feather key, left cover, right cover plate, pulley is installed on the slip copper sheathing by antifriction-bearing box, feather key is bolted in the slip copper sheathing, and left cover and right cover plate are fixed on antifriction-bearing box in the pulley by bolt.
Compared with prior art, gear rope sheave of the present utility model is by the rotation of antifriction-bearing box, avoid keeping off the situation that is in for a long time high-speed operation between the interior copper sheathing of rope sheave and the longitudinal axis, and the gear rope sheave is by slip copper sheathing and feather key, can be free to slide at the longitudinal axis, the neat actv. of the large rope of drilling well is aligned on the winch, is prolonging the service life of Winch rope arranger and the large rope of drilling well.
Description of drawings:
Fig. 1 is the utility model general assembly structural representation.
Fig. 2 is the utility model gear rope sheave A-A cross-sectional view.
The specific embodiment:
1 and 2 pair of the utility model is done following narration by reference to the accompanying drawings.
The utility model is comprised of pulley yoke assembly 1, gear rope sheave 5, between the first transverse axis 2a and the second transverse axis 2b that the first axle sleeve 3a and the second axle sleeve 3b of the longitudinal axis 4 of pulley yoke assembly 1 by its two ends is installed in pulley yoke assembly 1, have axially directed groove at the longitudinal axis 4; Gear rope sheave 5 is comprised of pulley 11, antifriction-bearing box 10, slip copper sheathing 7, feather key 6, left cover 9, right cover plate 13, pulley 11 is installed on the slip copper sheathing 7 by antifriction-bearing box 10, feather key 6 is fixed in the slip copper sheathing 7 by bolt 8, and left cover 9 and right cover plate 13 are fixed on antifriction-bearing box 10 in the pulley 11 by bolt 12.
The large rope of drilling well can slide in the circular space that is comprised of two gear rope sheaves 5 that are arranged side by side, the antifriction-bearing box 10 of pulley 11 interior installations is realized the radial rotating of gear rope sheave 5 on the longitudinal axis 4, feather key 6 on the slip copper sheathing 7 can be realized keeping off in the guide groove of rope sheave 5 on the longitudinal axis 4 and endwisely slip, slip copper sheathing 7 is by the rotation of antifriction-bearing box 10, can reduce the wearing and tearing of slip copper sheathing 7 and the longitudinal axis 4, prolong the service life of rope winding jib.
