In order to avoid the steel wire rope from being piled up and wound, a guide wheel is generally additionally arranged at the middle upper part of the drilling tower, and the additional arrangement of the guide wheel also has a problem: if the guide wheel is aligned with the center of a winding drum of the hoisting machine during drilling, the drilling machine moves backwards by 460mm, and when the drilling tool is lifted to drill, the steel wire rope is also accumulated and wound; if the guide wheel is aligned with the center of the winding drum of the hoisting machine during the drilling process under the condition of lifting, the steel wire rope can be piled up and wound as usual when the drilling machine moves forwards by 460mm for normal drilling.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the problem that exists among the above-mentioned prior art, provide a horizontal device of core drill hoist engine, can be horizontal with the hoist engine, the hoist engine central line is perpendicular with rig transmission direction, and is parallel with the overhead traveling crane axle, no matter the rig is bored or is carried the brill, and hoist engine wire rope smoothly neatly twines throughout, longe-lived, safe and reliable.

The utility model discloses a specific technical scheme be: the utility model provides a horizontal device of core drill hoist engine, includes the base, installs drive arrangement, transmission and hoist engine on the base, and the key is: the winch is transversely arranged, the shaft of the winch is perpendicular to the transmission direction of the drilling machine, and the shaft of the winch is parallel to the shaft direction of the crown block of the drilling tower; the driving device comprises a motor driven by a diesel engine; the transmission device comprises a clutch, a gear box, a transfer case and a transmission case, wherein the clutch is connected with the output end of the motor, the gear box is connected with the output end of the clutch, the output end of the gear box is connected with the transfer case, two output ends of the transfer case are respectively connected with the gyrator and the transmission case, and the output end of the transmission case is connected with the winch.

And a water brake is connected above the winch.

The utility model has the advantages that: the winding speed of the winch is adjusted and reduced by changing the pole number of the motor, the triangular belt speed reduction transmission and the transmission box speed reduction transmission, the winch has the advantages of speed reduction and stable transmission, the rope can be smoothly arranged without accumulation, and the service life is long.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic structural diagram of a vertical shaft type hydraulic drilling machine;

in the attached drawing, the device comprises a base 1, a base 2, a clutch 3, a gear transmission case 4, a transfer case 5, a transmission case 6, a gyrator 7, a winch 8, a derrick crown block 9 and a rope guide wheel.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings and specific embodiments: the utility model provides a horizontal device of core drill hoist engine, includes base 1, installs drive arrangement, transmission and hoist engine 7 on base 1, and the key is: the winch 7 is transversely arranged, a crankshaft of the winch 7 is vertical to the direction transmission of the drilling machine, the crankshaft of the winch 7 is parallel to the direction of the shaft of the crown block of the drilling tower, and the diameter of a winding drum of the winch 5 is 40 mm; the driving device comprises a motor driven by a diesel engine; the transmission device comprises a clutch 2, a gearbox 3, a transfer case 4 and a transmission case 5, wherein the clutch 2 is connected with the output end of a motor, the gearbox 3 is connected with the output end of the clutch 2, the output end of the gearbox 3 is connected with the transfer case 4, two output ends of the transfer case 4 are respectively connected with a gyrator 6 and the transmission case 5, and the output end of the transmission case 5 is connected with a winch 7.

The specific embodiment is shown in figure 1, a motor provides power for the whole device, the motor rotates a transmission clutch 2, the power is transmitted to a transfer case 4 through a gearbox 3 in a speed reduction manner, the transfer case 4 divides the force into two parts, one part of the force is transmitted to rear-end equipment through a gyrator 6 to provide power, the other part of the force is transmitted to a winch 7 through a transmission case 5 in a speed change manner and a direction change manner, the rotating speed of a winding drum is controlled, the gear transmission is more stable, the bearing force is larger, the winch 7 is transversely arranged, the shaft of the winch 7 is in the same transmission direction as that of a drilling machine, the shaft of the winch 7 is perpendicular to the shaft of a crown block of a drilling tower, the central line of the winch 7 is perpendicular to the transmission direction of the drilling machine and parallel to the shaft of the crown block, no matter whether the drilling machine drills or lifts the drilling machine;

as shown in fig. 2, the shaft of the hoist of the vertical shaft type hydraulic drilling machine is parallel to the direction transmission of the drilling machine and is vertical to the shaft direction of the crown block of the drilling tower, the shaft center of the gyrator of the drilling machine has a distance a with the hoisting center, and the upper part of the drilling machine can integrally move backwards by a distance B for the convenience of wellhead operation. Therefore, the distance between the hoisting center and the center line of a wellhead is changed into A + B, in order to ensure that a crown block pulley can be aligned to the wellhead and a steel wire rope led out of the crown block can be aligned to the hoisting center, thereby avoiding the phenomenon of hoisting disorder, the middle upper part of the drilling tower is provided with a rope guide wheel, the center distance of the center wellhead of the rope guide wheel is A + B, but if the guide wheel is aligned to the center of a winding drum of the hoisting machine during drilling under the condition that the drilling machine moves forwards by 460mm for normal drilling, the steel wire rope is piled up and wound as usual; and this application is through the improvement of horizontal device after for 7 drum shafts of hoist engine's direction is parallel with 8 axle directions of rig overhead traveling crane, does not need structures such as rope guide pulley, no matter how the rig antedisplacement or backward shift, can not form indiscriminate rope phenomenon, and the winding displacement is neat, safe and reliable.
