Description

The pinion and-rack bont
Technical field
The utility model belongs to the oil-well rig technical field, relates to a kind of pinion and-rack bont.
Background technology
The elevator system of conventional oil rig generally is made up of winch, overhead traveling crane, tourist bus, hook, water cock, wireline anchor, steel rope, rope winding jib etc.Conventional hoisting system of rig drives the hook, water cock (or drive on the top) and the drilling tool up-and-down movement of suspension that are suspended on the tourist bus bottom through winch rotation lay winding wire ropes through overhead traveling crane (fixed pulley), tourist bus (movable pulley) and accomplishes enhanced feature.This kind structure is the most frequently used hoisting system of rig form at present; Main existing problems are: complex structure, and equipment is huge, the trouble point is many, maintaining point is many, buying and use cost height, the transmission of power chain length; Mechanical efficiency is low, put forward function, the operation of can not pressurizeing on having only simultaneously.
Summary of the invention
The purpose of the utility model provides a kind of pinion and-rack bont, is matched in the tooth bar rig, has solved huge, the problems such as maintenance is difficult, efficient is low, cost height of equipment of existing conventional hoisting system of rig.
The technical scheme that the utility model adopted is; A kind of pinion and-rack bont; On the lifting support body, be symmetrically installed with double-type lift unit; The mouth that each lift unit is included in motor is connected with drop-gear box, at each reduction gearbox output shaft end gear is installed, and at the motor end joint connection brake gear is arranged; On the gadder axis, tooth bar is installed, all wheel and racks are connected with a joggle; In the gadder both sides along being provided with slide rail, about the left side that promotes support body, the right side respectively installs a cover leading sheave up and down; At lifting support body top hydraulic efficiency pressure system is installed, hydraulic efficiency pressure system is connected with all brake gears.
The beneficial effect of the utility model is to compare with background technology; 1) saves overhead traveling crane, tourist bus, hook, steel rope, wireline anchor, winch, rope winding jib etc., simple in structure, compact dimensions, in light weight, buying and use cost is low, maintaining is simple, damageable spare parts is few.2) accomplish lifting and lowering function through direct geared up-and-down movement on tooth bar, driving efficiency is high.3), not only can accomplish lifting and transfer operation, the operation of also can pressurizeing through the rack-and-gear positive drive.
Description of drawings
Fig. 1 is the utility model bont side-looking structural representation;
Fig. 2 is the utility model bont master TV structure scheme drawing;
Fig. 3 is the utility model bont plan structure scheme drawing.
Among the figure, 1. gear, 2. bearing cap shim, 3. bolt A 4. promotes support body, 5. drop-gear box, 6. motor, 7. brake gear, 8. left leading sheave, 9. bolt B, 10. hydraulic efficiency pressure system, 11. right leading sheaves, 12. tooth bars, 13. slide rails, 14. top driving devices.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
Like Fig. 1, Fig. 2, Fig. 3; The structure of the utility model is; Promoting symmetrical double-type 2 covers, 4 covers or the 6 cover lift units of being equipped with on the support body 4, the mouth that every cover lift unit is included in motor 6 is connected with drop-gear box 5, and each drop-gear box 5 is captiveed joint with lifting support body 4 through bolt A3; At each drop-gear box 5 output axle head gear 1 is installed, brake gear 7 is arranged at motor 6 end joint connections; Tooth bar 12 is installed on the gadder axis, and all gears 1 are double-type to be connected with a joggle with tooth bar 12; The edge is provided with slide rail 13 in the gadder both sides; In the left side that promotes support body 4 up and down through bolt 9 the left leading sheave of a cover 8 respectively is installed, the right side that promotes support body 4 respectively installs the right leading sheave 11 of a cover through bolt 9 up and down; All left leading sheaves 8 can slide up and down along the slide rail 13 of both sides with right leading sheave 11, are provided with bearing cap shim 2 between all pulley bases and the lifting support body 4; At lifting support body 4 tops hydraulic efficiency pressure system 10 is installed, hydraulic efficiency pressure system 10 is connected with all brake gears 7; Promoting support body 4 lower ends is connected with top driving device 14.
The utility model device; Rotatablely move with tooth bar 12 engagements that are fixed on the drilling derrick through motor 6 (or HM Hydraulic Motor) and drop-gear box 5 driven gears 1 when making a trip; Thereby driving top driving device 14 and drilling tool thereof raises and decentralizes; Left side leading sheave 8 and right leading sheave 11 move and for bont provides guiding, guarantee lifting process perpendicular movement up and down through bearing cap shim 2 along being fixed on slide rail 13 on the drilling derrick respectively, make drilling tool not depart from well head.Motor 6, drop-gear box 5 and gear 1 are checked in 7 actions of hydraulic efficiency pressure system 10 control brake gears during brake, guarantee that bont hovers on the tooth bar 12.
Conventional hoisting system of rig promotes operation through steel rope, and the winding efficient of steel rope is low, and the utility model rack-and-gear rig is accomplished enhanced feature through direct geared up-and-down movement on tooth bar, and driving efficiency is high.In addition, because steel rope is flexible, can't accomplish pressurization function, and the novel bont of the utility model not only can be accomplished lifting and transfer operation, the operation of also can pressurizeing through the rack-and-gear positive drive.
The utility model is compared with existing conventional hoisting system of rig; Save overhead traveling crane, tourist bus, hook, steel rope, wireline anchor, winch, rope winding jib etc., simple in structure, compact dimensions, in light weight, buying and use cost is low, maintaining is simple, damageable spare parts is few, driving efficiency is high.
