Abstract
The utility model relates to self return oil tube slide cars for oilfield operation. The utility model is characterized in that a right slide rail and a left slide rail are installed in parallel, the left slide car and the right slide car are connected by pull wires, both ends of each of the right slide rail and the left slide rail are provided with rail pulleys, the pull wires are wound on the rail pulleys, pulleys are arranged between the left slide car and the left slide rail and between the right slide car and the right slide rail, springs are arranged on the pull wires, lateral pulleys are arranged between the left slide car and the left slide rail and between the right slide car and the right slide rail, and the lateral pulleys are installed on the left slide car and the right slide car. One end of the oil tube is placed on the right slide car, when the other end of the oil tube is hoisted or lowered by a well repairing machine, the right slide car is frontward walked or is backwards walked, and simultaneously the left slide car is backwards walked or is frontward walked under the action of the pull wires, and alternative walk continues in the manner to complete the transportation task of the oil tube. A worker doesn't need to push back the utility model from one end of the rail to the other end of the rail, which reduces work amount of the worker. The lateral pulleys are arranged between the left slide car and the left slide rail and between the right slide car and the right rail, so the utility model has the advantage of very high stability.
Description
One, technical field
The utility model be the on-the-spot usefulness of oil field operation well workover return the oil pipe coaster certainly, belong to engineering goods.
Two, background technology
During oil well operation well workover, oil pipe be tripped out horizontal drain in the well and put on ground, also the oil pipe that lies in a horizontal plane in ground will be lowered in the oil well again, this two procedures all will make oil pipe from vertically becoming level or level becomes vertically.Oil pipe is being become the vertical process from vertically becoming level or level, and an end of oil pipe need slide on ground rail, and in sliding process, the screw thread and the track of oil pipe one end that weares and teares easily cause the screw thread blow-by, cause that oil well is not fuel-displaced.For addressing this problem, the operation team that has at present adopts simple oil pipe coaster between tubing round thread end and track, but this oil pipe coaster needs operating worker that it is back into the other end of track again from track one end after being drawn to the other end of track by the power of workover rig from track one end.When this oil pipe coaster used at the scene, the operating worker workload was big, the labour intensity height, and job scheduling is slow.Therefore, this oil pipe coaster seldom uses at the scene, and operating worker would rather the wear and tear screw thread and the track of oil pipe one end do not adopt this oil pipe coaster yet.
Three, summary of the invention
The purpose of this utility model provides a kind of from returning the oil pipe coaster, this from returning the oil pipe coaster after it is drawn to the other end of track by the power of workover rig from track one end, do not need operating worker that it is back into the other end of track again from track one end, it can turn back to the other end of track automatically from track one end, make it reduce the operating worker workload, reduce labor intensity, improve job scheduling, and have very high stability.
The purpose of this utility model is achieved in that by left coaster, right slide rail, left slide rail, draught line, right coaster to be formed, right slide rail, the parallel installation of left slide rail, right coaster is on right slide rail, and left coaster is on left slide rail, and left coaster, right coaster are connected by draught line.Right slide rail, left slide rail two ends attachment rail pulley, draught line is around on the track pulley.Between left side coaster and left slide rail, right coaster and the right slide rail pulley is arranged, pulley is installed on left coaster, the right coaster.Spring is arranged on the draught line.Between left side coaster and left slide rail, right coaster and the right slide rail side direction pulley is arranged, the side direction pulley is installed on left coaster, the right coaster.This from returning the oil pipe coaster in use, it is placed on operation field, one end that need trip out in the well with the oil pipe of G.I.H is placed on the right coaster, the other end of oil pipe is sling by the operation workover rig or when putting down, right coaster is walked forward or walking backward, under the effect of draught line, left side coaster is walking or walking backward forward simultaneously, left side coaster, right coaster move towards the other end of slide rail separately respectively, so alternately walk, and finish the conveying task of oil pipe.
The beneficial effects of the utility model are: do not need operating worker that it is back into the other end of track again from track one end, reached minimizing operating worker workload, reduce labor intensity, improve the purpose of job scheduling.Owing between left coaster and left slide rail, right coaster and the right slide rail side direction pulley is arranged, therefore, has very high stability.
Four, description of drawings
Fig. 1 is the utility model embodiment assembled view.
Fig. 2 is the utility model embodiment slide rail profile.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Form by left coaster 1, right slide rail 3, left slide rail 4, draught line 5, right coaster 6, right slide rail 3, the 4 parallel installations of left slide rail, right coaster 6 is on right slide rail 3, and left coaster 1 is on left slide rail 4, and left coaster 1, right coaster 6 are connected by draught line 5.Right slide rail 3, left slide rail 4 two ends attachment rail pulleys 7, draught line 5 is around on the track pulley 7.Between left side coaster 1 and left slide rail 4, right coaster 6 and the right slide rail 3 pulley 8 is arranged, pulley 8 is installed on left coaster 1, the right coaster 6.Spring 2 is arranged on the draught line 5.Between left side coaster 1 and left slide rail 4, right coaster 6 and the right slide rail 3 side direction pulley 9 is arranged, side direction pulley 9 is installed on left coaster 1, the right coaster 6.This from returning the oil pipe coaster in use, it is placed on operation field, one end that need trip out in the well with the oil pipe of G.I.H is placed on the right coaster, the other end of oil pipe is sling by the operation workover rig or when putting down, right coaster is walked forward or walking backward, under the effect of draught line, left side coaster is walking or walking backward forward simultaneously, left side coaster, right coaster move towards the other end of slide rail separately respectively, so alternately walk, and finish the conveying task of oil pipe.
