Background Art

[0002] At present, in geological survey tasks, fully hydraulic drilling rigs are widely used because of their stable operation, convenient and safe operation. However, when facing deep hole geological survey, the fully hydraulic drilling rig has insufficient rotational torque, which will cause risks in deep hole survey, and it is very easy to cause accidents such as drill stuck and drill buried, resulting in huge losses. If a mechanical top drive drilling rig is used for deep hole geological survey, its efficiency is not as good as that of a fully hydraulic drilling rig. Therefore, in order to prevent the occurrence of drill stuck and drill buried accidents, the power of the fully hydraulic drilling rig has to be increased, which increases the cost of shallow hole drilling.

DETAILED DESCRIPTION

[0025] The following will be combined with specific embodiments and attached Figure 1-8 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the preferred embodiments of the present invention, rather than all the embodiments. Those skilled in the art can make similar modifications without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0026] The present invention provides a steering and transmission housing 1 (such as Figure 4 , Figure 5As shown in the figure, the steering box 11 includes a steering box 11, a first power input end 12, a first power output end 13, and a first transmission assembly. Two first support shafts 111 are symmetrically arranged at the lower part of the steering box 11. In practical applications, the corresponding ends of the first support shafts 111 are flange-shaped, and the flange-shaped ends are fixedly arranged on the steering box 11 by bolt connection. The steering box 11 can be rotated around the axis of the first support shaft 111 in the circumferential direction by using the rotation support of the two first support shafts 111. The first power The input end 12 is rotatably arranged at the lower part of the steering box 11, and the axis of rotation of the first power input end 12 relative to the steering box 11 is coaxially distributed with the axis of the first support shaft 111. Since the first power input end 12 is rotatably arranged relative to the steering box 11 and the rotation axis is coaxially distributed with the rotation axis of the steering box 11, when the steering box 11 rotates around the first support shaft 111, the first power input end 12 can remain stationary. Therefore, in practical applications, this feature can be used to adjust the angle of the steering box 11 after the angle is adjusted or the angle is adjusted. During the degree adjustment process, driving force can be continuously input to the first power input end 12, and the first power output end 13 is vertically arranged on the upper left side of the steering box 11. By using the above design method, the angle of the first power input end 12 relative to the steering box 11 and the first power output end 13 is not fixed, so that when the first power input end 12 has a stable power input, the angle of the first power output end 13 can be changed according to actual needs to achieve variable-angle power output; the first transmission assembly is arranged in the steering box 11, and the power of the first power input end 12 can be transmitted to the first power output end 13 through the first transmission assembly in the steering and transmission box 1. After the steering box 11 is rotated and adjusted, the direction of the first power output end 13 is adjusted. The direction adjustability of the first power output end 13 can meet the continuous power input of the actuator with angle changes. For example, in the existing drilling rig, the direction of the mast can be adjusted according to needs. After the mast is adjusted, the steering and transmission box 1 can still meet the power requirements of some actuators located on the mast.

The hexagonal transmission rod 31 is sleeved in the hexagonal through hole in the sixth transmission shaft 541, and the rotation of the hexagonal transmission rod 31 drives the rotation of the sixth transmission shaft 541. The third transmission gear 542 is sleeved on the outside of the sixth transmission shaft 541, and the rotation of the sixth transmission shaft 541 drives the synchronous rotation of the third transmission gear 542.

The prime mover 21, the gearbox 22, the transfer case 23, the reversing case 24, and the oil pump 25 are all known mature technical products in the mechanical field, so the specific working principles and structures of the prime mover 21, the gearbox 22, the transfer case 23, the reversing case 24, and the oil pump 25 are no longer described in detail; the prime mover 21 can be a gasoline engine or a diesel engine or a gas engine. In this specific embodiment, the prime mover 21 uses a diesel engine. The prime mover 21 is arranged on the common crawler chassis 2, and the oil pump 25 is laterally connected to the left side of the prime mover 21. Specifically, the oil pump 25 is connected to the power output end corresponding to the prime mover 21 through a second universal joint coupling 251. The gearbox 22 is connected to the right side of the prime mover 21, and the transfer case 23 is arranged on the On the right side of the gearbox 22, specifically, the transfer case 23 realizes a transmission connection with the power output end corresponding to the gearbox 22 through the third universal joint coupling 232, and a shift handle 231 is arranged on the transfer case 23. The reversing case 24 is arranged on the right side of the transfer case 23, and the power output end of the reversing case 24 is connected to the third transmission shaft 122. Specifically, the power output end of the reversing case 24 adopts a first universal joint coupling 241 to realize a transmission connection with the third transmission shaft 122.

The oil pump 25 delivers or cuts off the power hydraulic oil to the mast lifting cylinder 4 and the hydraulic motor 531 through the corresponding hydraulic system pipelines, and uses the relevant hydraulic control valves in the hydraulic system pipelines to achieve forward or reverse switching of the mast lifting cylinder 4 and the hydraulic motor 531.

[0034] In actual application, outrigger cylinders are arranged around the brackets on the common crawler chassis 2. During drilling operation, the bottom of the outrigger cylinders is in contact with the ground.

During the drilling process, when it is necessary to apply mechanical driving force to the drill rod in order to increase the torque of the drill rod, the hydraulic driving force of the drill rod is cut off by operating the first shift hydraulic cylinder 5341, and then the clutch of the gearbox 22 is disengaged, and the shift handle 231 of the transfer case 23 is turned to the right end position, so as to realize the transmission of mechanical power to the reversing box 24, and the power of the reversing box 24 is transmitted to the sixth transmission shaft 541, and the second shift hydraulic cylinder 5451 is used to realize the synchronous engagement of the fourth transmission gear 544 with the second transmission gear 523 and the third transmission gear 542, and then finally the input of mechanical power to the drill rod is realized, and then further drilling operations can be continued on the basis of the previous drilling depth, thereby completing the deep hole exploration operation.
