Description
Technical field
The utility model belongs to petroleum well workover plant machinery field, particularly tractor hoist field, particularly relates to a kind of sledge and fills rotary tractor hoist.
Background technology
Offshore production platform on a platform or land cluster well is distributed in for there being Duo Koujing, due to more at an area distribution oil well, workover treatment is more frequent, a workover rig is fixed on cluster well region, a land or an offshore production platform, making this workover rig is for a long time the well services in this region, be a kind of not only economy but also practical operational method, the remote driving functions of wheeled workover rig is no longer applicable; At present, cluster well both domestic and external mainly adopts sledge to fill the mode of workover rig translation in orbit, realizes a workover rig to the workover treatment of many mouthfuls of wells.
But, for the simple and easy offshore production platform of a large amount of shallow seas, shallow well or the remote land cluster well of a part of geographical location comparison, adopt sledge dress rail mounted workover rig to there is many defects: one is that track can take a large amount of platforms or ground space, make natively narrow and small platform or ground space more crowded; Two is that sledge dress rail mounted workover rig build is comparatively large, and weight is subject to the load-bearing restriction of simple and easy offshore production platform; Three is sledge dress rail mounted workover rig complex structures, and operation and maintenance cost is higher.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provide a kind of rotated by upper bed-plate and then solve the sledge laying track, weight restricted problem and realize many well operations fill rotary tractor hoist.
The purpose of this utility model is achieved in that a kind of sledge fills rotary tractor hoist, comprise actuating unit, control the operating room of actuating unit work and the operation wellhead device be connected with actuating unit by wire rope, wherein actuating unit comprises motor, the gearbox be connected with engine power output, the angle gear-box be connected with gearbox by front propeller shaft, by the winch that inter-axle shaft is connected with angle gear-box, wherein said motor, gearbox, angle gear-box, winch and operating room are fixedly mounted on upper bed-plate, lower bottom base is equipped with in the underneath of upper bed-plate, circular hole is offered in the middle of upper bed-plate, the circular hole that corresponding upper bed-plate is offered is installed with central axis in the centre of lower bottom base, the circular hole that upper bed-plate is offered matches with the central axis of lower bottom base and is sleeved on the central axis of lower bottom base, and upper bed-plate rotates on lower bottom base around the central axis of lower bottom base.
Described operation wellhead device is arranged on each well head place of cluster well, comprise and be arranged on ground workover derrick and lower sheave, lower sheave is fixed on the ground below workover derrick, traveling system on workover derrick is connected with one end of wire rope, the wire rope other end walks around lower sheave coiling on winch, sledge fills rotary tractor hoist and is placed on centre position, cluster well region, the different rotary angle of adjustment upper bed-plate on lower bottom base, make winch rope outlet direction towards the well head of different wells needing operation, and to upper bed-plate, lower bottom base is reliably fixed, prevent the tractor hoist when operation from producing mobile or rotating.
The utility model has following good effect: 1, without the need to track, solves the problem of laying the large quantity space of orbit occupancy, saves platform and ground space; 2, small, lightweight, solve problem by simple and easy offshore production platform load-bearing restriction; 3, adopt rotary, achieve the workover treatment of same position to around many mouthfuls of wells, structure is simple, easy to use, decreases operation and maintenance cost.

Detailed description of the invention
A kind of sledge fills rotary tractor hoist as shown in Figure 1,2,3, 4, comprises lower bottom base 1, upper bed-plate 2, motor 3, gearbox 4, angle gear-box 5, winch 6, operating room 7, front propeller shaft 8, inter-axle shaft 9.Described gearbox 4 is connected with motor 3, and described angle gear-box 5 is connected with gearbox 4 by front propeller shaft 8, and described winch is connected with angle gear-box 5 by inter-axle shaft 9; Described motor 3, gearbox 4, winch 6, angle gear-box 5 are fixed on upper bed-plate 2, circular hole is provided with in the middle of described upper bed-plate 2, central axis is provided with in the middle of described lower bottom base 1, circle hole sleeve in the middle of upper bed-plate 2 is contained on lower bottom base 1 central axis, circular hole in the middle of upper bed-plate 2 coordinates with the central axis of lower bottom base 1, and upper bed-plate 2 can rotate on lower bottom base 1 around central axis.
Workover derrick 12 and lower sheave 11 are installed near each well head of cluster well, sledge is filled rotary tractor hoist and be placed on appropriate location in the middle of cluster well region, adjustment upper bed-plate 2 angle, make winch rope outlet direction towards the well head of well needing operation, and upper bed-plate 2, lower bottom base 1 are reliably fixed, prevent the tractor hoist when operation from producing mobile or rotating; Wire rope 10 on winch is walked around lower sheave 11 and is connected with the traveling system on workover derrick 12, just can carry out workover treatment; When a bite well operations is complete, when needing to carry out operation to other any a bite well of cluster well region, do not need the position of mobile tractor hoist, as long as rotate upper bed-plate 2 to suitable angle, just can carry out workover treatment to another mouthful of well.
