Abstract
The utility model discloses a drill-pipe carriage driving device. The drill-pipe carriage driving device comprises a drill stand and a drill pipe arranged on the drill stand. The drill-pipe carriage driving device is characterized in that one end of the drill pipe is connected with a drill pipe rotation driving assembly, and the other end of the drill pipe is connected with a lower support; the drill pipe is provided with an upper carriage and a middle carriage which are in sliding connection with the drill stand; one end of the drill stand is provided with a pulley block and a lifting pulley, the other end of the drill stand is provided with an oil cylinder and a lower pulley block, the oil cylinder is connected with a cylinder head pulley block, and the cylinder head pulley block is connected with the pulley block, the lifting pulley, a pulling-down pulley and the lower pulley block through a lifting steel wire rope, a pulling-down steel wire rope and a neutral-position steel wire rope. According to the drill-pipe carriage driving device, along with stretching-out and drawing-back of the oil cylinder, the upper carriage is lifted or descends, and meanwhile the middle carriage is lifted or descends. The drill-pipe carriage driving device is simple and compact in structure and convenient to maintain. The problem that the pulleys and sliding blocks bear force unevenly because the elongation percentages of the steel wire ropes are different can be solved effectively, and the drill pipe can be protected most effectively.
Description
technical fieldthe utility model belongs to Drill Pipe Technology field, relates to a kind of drilling rod skid actuating device.
background technologythe boom hoist cable of conventional drill and drop-down wire rope all adopt respectively two wire rope to drive, in use, the elongation rate difference of wire rope causes user frequently to regulate tightness of steel wire rope degree, otherwise will inevitably cause the excessive wear of pulley and slide block, affects its application life.
summary of the inventionthe purpose of this utility model is to solve prior art to have the technical problem of using inconvenience and pulley and slider wear, provides a kind of drilling rod skid actuating device, to overcome the deficiencies in the prior art.
A kind of drilling rod skid actuating device of the utility model, it comprises drilling cramp and is arranged on the drilling rod on drilling cramp; Its main points are that one end of drilling rod is connected with drilling rod rotary actuation assembly, and the other end is connected with lower support; Described drilling rod is provided with upper balladeur train and the middle balladeur train being slidably connected with drilling cramp; One end of described drilling cramp is provided with assembly pulley and lifting tackle, the other end of drilling cramp is provided with oil cylinder and downslide wheels, oil cylinder is connected with cylinder head assembly pulley, and cylinder head assembly pulley is connected with assembly pulley, lifting tackle, drop-down pulley and downslide wheels by boom hoist cable, drop-down wire rope and meta wire rope.
Described cylinder head assembly pulley is comprised of two double grooved pulleys, and the cylinder head of described meta wire rope and oil cylinder is connected, thereby oil cylinder shrinks the upper balladeur train of drive and the action of middle balladeur train.
The utility model drilling rod skid actuating device, flexible along with oil cylinder, balladeur train promotes or descending time in realization, the lifting of balladeur train or descending in also realizing.Simple and compact for structure, easy to maintenance.The pulley that can effectively solve rope stretch rate difference and bring and the problem of slide block unbalance stress, and can realize drilling rod is protected most effectively.
accompanying drawing explanationaccompanying drawing is the utility model structural representation.
In figure 1, drilling rod rotarilys actuate assembly 2, upper balladeur train 3, drilling rod 4, middle balladeur train 5, drilling cramp 6, downslide wheels 7, meta wire rope 8, drop-down wire rope 9, boom hoist cable 10, assembly pulley 11, oil cylinder 12, drop-down pulley 13, cylinder head assembly pulley 14, lifting tackle 15, lower support
the specific embodimentwith reference to the accompanying drawings, the utility model it comprise drilling cramp 5 and be arranged on the drilling rod 3 on drilling cramp 5; One end of drilling rod 3 rotarilys actuate assembly 1 with drilling rod and is connected, and the other end is connected with lower support 15; Described drilling rod 3 is provided with upper balladeur train 2 and the middle balladeur train 4 being slidably connected with drilling cramp 5; One end of described drilling cramp 5 is provided with assembly pulley 10 and lifting tackle 14, the other end of drilling cramp 5 is provided with oil cylinder 11 and downslide wheels 6, oil cylinder 11 is connected with cylinder head assembly pulley 13, and cylinder head assembly pulley 13 is connected with assembly pulley 10, lifting tackle 14, drop-down pulley 12 and downslide wheels 6 with meta wire rope 7 by boom hoist cable 9, drop-down wire rope 8; Described cylinder head assembly pulley 13 is comprised of two double grooved pulleys, and described meta wire rope 7 is connected with the cylinder head of oil cylinder 11, thereby oil cylinder shrinks the upper balladeur train 2 of drive and 4 actions of middle balladeur train.
the effect of each parts of the utility model and operating principle:
The utility model by oil cylinder provide upper balladeur train and in the power source of balladeur train, hydraulic motor drives drilling rod rotary actuation assembly to drive drilling rod to rotate by reductor and shaft coupling, thereby realize the function of drilling rod boring, along with stretching of oil cylinder, balladeur train promotes or descending time in realization, the lifting of balladeur train or descending in also realizing; Boom hoist cable two ends are bolted on balladeur train bottom, walk around respectively assembly pulley, cylinder head assembly pulley and lifting tackle, thereby balladeur train hoisting velocity is 2 times of oil cylinder stretching speed in realization, lifting tackle has effectively been avoided rope stretch rate in use procedure different and pulley and the over worn problem of slide block brought from the use of boom hoist cable; Drop-down wire rope two ends are bolted on balladeur train bottom, walk around respectively downslide wheels, cylinder head assembly pulley and drop-down pulley, thereby the drop-down speed of balladeur train is 2 times of oil cylinder stretching speed in realization, drop-down pulley has effectively been avoided rope stretch rate in use procedure different and pulley and the over worn problem of slide block brought from the use of drop-down wire rope; Meta wire rope two ends link together by screw rod, wire rope is connected in oil cylinder head bottom and middle balladeur train bottom by bolt and fixed block, walk around respectively assembly pulley and downslide wheels, thereby in realizing, the balladeur train speed of service equals oil cylinder stretching speed, in middle balladeur train running, be positioned at all the time the centre position of balladeur train and lower support, for drilling rod provides the most effectively protection; In upper balladeur train lifting or downdraw process, boom hoist cable equates with the linear velocity of drop-down wire rope, thus use double flute cylinder head assembly pulley, thus more effectively utilize space, make more compact structure.
