Motor power of a lifting system is directly transmitted to the top driving assembly for rotation through the clutches, so that the number of equipment of the whole lifting and rotating device is reduced and the weight of the whole lifting and rotating device is lightened.
Description
Technical field
The utility model belongs to the petroleum machinery equipment technical field, relates to a kind of lifting rotary joint actuating device.
Background technology
The elevator system of conventional oil rig mainly is made up of winch, overhead traveling crane, tourist bus, hook, water cock, wireline anchor, steel rope, rope winding jib etc., drives the hook, water cock (or assembly is driven on the top) and the drilling tool up-and-down movement of suspension that are suspended on the tourist bus bottom by winch rotation lay winding wire ropes through overhead traveling crane (fixed pulley), tourist bus (movable pulley) and accomplishes enhanced feature.Rotary system generally drives assembly drop-gear box input end imput power by propulsion source through the top, drives the top and drives assembly and rotate and realize drilling tool rotary drilling function.Adopt a kind of bont at present, be matched in the tooth bar rig, solved difficult, the problems such as efficient is low, cost height of existing conventional hoisting system of rig maintenance.Because the assembly rotary power is driven respectively by motor-driven in bont power and top, supporting control system also needs two covering devices, brings whole bont equipment to increase, and weight, cost etc. all increase greatly.
Summary of the invention
The purpose of the utility model provides a kind of lifting rotary joint actuating device; Solved the elevator system and the separately-driven shortcoming of rotary system of existing conventional bont, made the minimizing of whole lifting slewing arrangement equipment, weight saving, supporting control system of while also reduce two covering devices, cost reduction accordingly.
The technical scheme that the utility model adopted is that a kind of lifting rotary joint actuating device is respectively installed one and put leading sheave about the upper end that promotes support body, leading sheave under the cover respectively is being installed about the lower end that promotes support body; In the lower end that promotes support body the top is installed and drives assembly;
In promoting the framework of support body, be horizontally disposed with four groups of drop-gear boxs, comprised upper strata totally two groups of drop-gear box A of totally two groups of drop-gear box B and lower floor, each reduction gearbox output shaft end is provided with gear separately, and each drop-gear box other end all is connected with a motor; The every group of drop-gear box A in below is built-in with a power-transfer clutch A, and the two groups of drop-gear box A in below drive assembly through the power-transfer clutch B while separately with the top in addition and are in transmission connection.
The beneficial effect of the utility model is; Compared with prior art; The drive motor of assembly is driven on cancellation top, through power-transfer clutch the motor power of elevator system is directly passed to the top and drives assembly and be rotated work, makes that whole lifting slewing arrangement equipment reduces, weight saving; Can drive the control system that the assembly motor is driven on the top, cost-cutting for the tooth bar rig saves.

Fig. 3 is that the utility model promotes the rotary device structure schematic side view;
Among the figure, 1. brake gear, 2. motor, 3. power-transfer clutch A, 4. drop-gear box A, 5. gear, 6. power-transfer clutch B, 7. assembly is driven on the top, 8. goes up leading sheave, and 9. hydraulic efficiency pressure system 10. promotes support body, 11. times leading sheaves, 12. drop-gear box B.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
With reference to Fig. 1, Fig. 2, Fig. 3, the structure of the utility model device is, about the upper end that promotes support body 10, respectively installs one and puts leading sheave 8, and leading sheave 11 under the cover respectively is being installed about the lower end that promotes support body 10; Be provided with hydraulic efficiency pressure system 9 in lifting support body 10 upper ends, in the lower end that promotes support body 10 top be installed and drive assembly 7; In the framework that promotes support body 10, four groups of drop-gear boxs have been horizontally disposed with; Comprise upper strata totally two groups of drop-gear box A4 of totally two groups of drop-gear box B12 and lower floor; Each reduction gearbox output shaft end (same end) is provided with gear 5 separately; Each drop-gear box other end all is connected with a motor 2, and each motor 2 correspondence is connected with a cover brake gear 1, and all brake gears 1 are communicated with hydraulic efficiency pressure system 9; Respectively be equipped with a power-transfer clutch A3 in the two groups of drop-gear box A4 in below, the two groups of drop-gear box A4 in below drive assembly 7 through the power-transfer clutch B6 while separately with the top in addition and are in transmission connection.
The principle of work of the utility model device is:
When making a trip; Power-transfer clutch B6 does not act on; Four motors 2 (or HM Hydraulic Motor) drive two groups of drop-gear box B12 and two groups of drop-gear box A4 driven gears 5 rotate with fixing tooth bar engagement; Leading sheave 8 also provides guiding for promoting slewing arrangement with leading sheave 11 along pulley left side track and the right orbiting motion of pulley, raises and decentralizes thereby drive drilling tool.
During boring by rotation, power-transfer clutch B6 effect, two groups of drop-gear box B12 do not work, and two groups of motors 2 are passed to the top through two groups of drop-gear box A4 and power-transfer clutch B6 separately (this moment, power-transfer clutch A3 did not act on) with power and are driven assembly 7, thereby realize the boring by rotation function.
Motor 2, drop-gear box A4 and power-transfer clutch A3, gear 5 are checked in 1 action of hydraulic efficiency pressure system 9 control brake gears during brake, guarantee to promote slewing arrangement and hover on the tooth bar.
The lifting slewing arrangement of the utility model through supporting motor, drop-gear box, gear, brake gear in pairs is installed in promoting support body, is fixed on drop-gear box, motor on the lifting support body simultaneously; Respectively arrange a cover leading sheave up and down what promote slewing arrangement, the top is driven assembly and is installed in the bont bottom.Compare with existing conventional bont; Cancelled and pushed up the drive motor that drives assembly; Through power-transfer clutch the motor power of elevator system is directly passed to the top and drives assembly and be rotated work, make that whole lifting slewing arrangement equipment reduces, weight saving, it is more flexible to work.
