Description
Technical field
The utility model relates to a kind of core exploring equipment, particularly a kind of novel hoist engine of all-hydraulic core exploratory drilling rig.
Background technology
The hoist engine of full hydraulic rock core drilling machine is generally selected the crane of using on the crane for use in the prior art, by equalizing valve control lifting, the decline drilling tool has reached and has pulled out sleeve pipe.Because it is at the uniform velocity in lifting or decline process all the time, adopts same rotating speed, along with the increase of drilling depth, the weight of drilling tool is increasing, and its efficient reduces greatly, and causes runaway accident easily.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of novel hoist engine of safe in utilization, all-hydraulic core exploratory drilling rig that efficient is high.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of novel hoist engine of all-hydraulic core exploratory drilling rig, comprise reel and planet gear transmission system, one end of reel is provided with the descending system actuation mechanism, the other end of reel is provided with the lifting arrestment mechanism, be characterized in: power transmission shaft one end of planet gear transmission system is connected with hydraulic motor by a planetary gear reducing gear, the other end at above-mentioned power transmission shaft is provided with one and reel stationary output shaft, and output shaft is connected with a hydromatic brake by clutch.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, described clutch comprises the ring gear that is located on the output shaft, on the power shaft of hydromatic brake, be provided with the clutch gear that is slidingly matched by spline, the clutch driving lever is housed on the clutch gear.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, promotes arrestment mechanism and comprises lifting system circle and promote brake that described lifting system circle is fixedlyed connected with the planetary gear carrier of planetary transmission system.
The utility model discloses a kind of novel hoist engine of all-hydraulic core exploratory drilling rig, be mainly used in lifting, the decline drilling tool has reached and pulled out sleeve pipe.Adopt the hoist engine of planetary gear structure, an end of hoist engine is equipped with the hydromatic brake device, and cooperates with lifting, descending system actuation mechanism.When drilling tool weight is little, can unclamp the descending system actuation mechanism, drilling tool descends under the deadweight effect fast.When drilling depth increases, when drilling tool weight increases, be connected with the hydromatic brake device, braking moment by the hydromatic brake generation, regulate the decrease speed of drilling tool, when the driving moment of action of gravity on reel of the braking moment of hydromatic brake and drilling tool tended to balance, drilling tool was with at the uniform velocity or near at the uniform velocity descending.When drilling tool reaches certain weight, also need to be used with the decline check mechanism again, reach safer decrease speed.Compared with prior art, the utility model compact conformation, safe in utilization, efficient is high.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
The specific embodiment
A kind of novel hoist engine of all-hydraulic core exploratory drilling rig, adopt traditional planetary gear hoist engine, comprise reel 4 and planet gear transmission system 6, one end of reel 4 is provided with descending system actuation mechanism 3, the other end of reel 4 is provided with and promotes arrestment mechanism 5, power transmission shaft 9 one ends of planet gear transmission system 6 are connected with hydraulic motor 8 by a planetary gear reducing gear 7, the other end at above-mentioned power transmission shaft 9 is provided with one and reel 4 stationary output shaft 2, and output shaft 2 is connected with a hydromatic brake 1 by clutch.By the speedup casing of hydromatic brake 1, hoist engine one end is installed on the forebay of rig, and its structure is typical 2K-H planetary gear mechanism.By the series connection of two-stage epicyclic transmission mechanism, realized great speed reducing ratio.
Described clutch comprises the ring gear 12 that is located on the output shaft 2, is provided with the clutch gear 11 that is slidingly matched by spline on the power shaft of hydromatic brake 1, and clutch driving lever 10 is housed on the clutch gear 11.Promote arrestment mechanism 5 and comprise that the system of lifting is enclosed and the lifting brake, described lifting system circle is fixedlyed connected with the planetary gear carrier of planetary transmission system 6.
The hoist engine right-hand member promotes to be equipped with on the system circle and promotes brake 5, on the left end reel brake wheel decline brake 3 is housed.Handle respectively and promote brake or decline brake, can realize that hoist engine promotes, descends, brakes three kinds of different technological requirements such as drilling tool.
Promote drilling tool: unclamp the decline brake, handle and promote brake, check and promote the system circle, planetary gear is raised the train tie-rod of system circle, planetary gear carrier composition and fixes, can only rotation can not revolve round the sun (playing the intermediate setting wheel effect), this moment, power reached reel by elevator arbor, central gear, planetary gear, ring gear, reel was just being changeed and lay winding wire ropes, reached the purpose that promotes drilling tool.
Drilling tool weight light (as promoting empty elevator) needs again can suitably loosen the lifting brake when the lifting state is adjusted hoisting velocity, and this moment, planetary gear was that rotation is revolved round the sun again, can realize reducing the purpose of hoisting velocity.The decline drilling tool: unclamp when promoting brake, suitable release brake or be totally released brake, reel bores under the speed limit realizing in counter-rotating under the drilling tool deadweight effect.Planetary gear was in and promptly revolved round the sun and the motion state of rotation this moment.
Hydromatic brake is in the process of decline drilling tool, regulates the device of drilling tool decrease speed.Under when boring, it has absorbed the portion of energy that drilling tool descends and produced, the work that has alleviated friction brakes, thereby prolong the brake strap of the brake and promote life-span of system circle.
When reel reverses, the output shaft that is connected together with reel, drive clutch gear, by handling shift fork, clutch gear is meshed with output gear, drive rotor in the hydromatic brake relative stator and liquid in hydroecium and do gyration, produce the braking moment that constitutes by circulation moment and moment of friction.When the braking moment of hydromatic brake and the action of gravity of decline drilling tool on reel during the driving moment balance, drilling tool is with at the uniform velocity or near at the uniform velocity descending.
The braking moment of the fast more hydromatic brake of drilling tool decline is just big more, and hydromatic brake is provided with draining valve simultaneously, and the size that the control water yield flows out can make the different braking moment of hydromatic brake generation, thereby regulate the speed that drilling tool descends.
The braking moment of hydromatic brake is directly proportional with the quadratic power of rotor speed, have only when rotating speed reaches identical numerical value, decline moment that can the balance drilling tool, the balancing speed of the big more hydromatic brake of drilling tool weight is high more, and obviously the drilling tool lowering velocity should be than slow phase contradiction when heavily loaded with deep hole.Thereby, when heavy duty, often need to be used with brake, just can reach safe decrease speed.
