[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] Please also read Figures 1 to 4 Now, a rotating device with large torque continuous output for an open-pit drilling rig provided by the present invention is described. The rotary device for continuous output of large torque for open-pit drilling rigs comprises a rotary cylinder 1, a reciprocating piston 2, a control console 3, two groups of transmission gear assemblies 4 and a main shaft 5. The rotary cylinder 1 is divided into two groups, which are arranged at intervals and the power output ends are arranged opposite to each other. Both groups are used to output power, and the two groups of rotary cylinders 1 run alternately; driving gears 6 are sleeved on both ends of the reciprocating piston 2, and the reciprocating piston 2 has the freedom of reciprocating movement along its axial direction. The reciprocating movement of the reciprocating piston 2 makes the two groups of driving gears 6 alternately meshed and connected with the power output ends of the two groups of rotary cylinders 1; the control console 3 is connected to the two groups of rotary cylinders 1 and the reciprocating piston 2, and is suitable for controlling the start and stop of the two groups of rotary cylinders 1 and the reciprocating movement of the reciprocating piston 2 respectively; when the reciprocating piston 2 reciprocates, the two groups of driving gears 6 are alternately meshed and connected with the two groups of transmission gear assemblies 4; the main shaft 5 is meshed and connected with the two groups of transmission gear assemblies 4, and when the two groups of transmission gear assemblies 4 run alternately, both are used to transmit power to the main shaft 5 to continuously drive the main shaft 5 to rotate with a large torque.

[0022] The present invention provides a rotating device with large torque continuous output for open-pit drilling rigs. The rotating device is essentially a power device or a power output device. After being connected to the drilling tool, it can drive the drilling tool to realize rotational operation. Compared with the prior art, the present invention uses the reciprocating movement of the reciprocating piston 2 to make two groups of rotating cylinders 1 alternately drive two groups of transmission gear assemblies 4 to rotate and operate, thereby driving the main shaft 5 to output power with large torque rotation, replacing the rotary machine in the prior art, solving the technical problem of insufficient rotational torque of the drilling rig when drilling large holes or extra-large holes, which affects the drilling construction of the drilling rig, and has the technical effect of being able to continuously provide a large rotational torque, which is beneficial to drilling large holes or extra-large holes and improving the construction efficiency of the drilling rig.

[0023] As a specific embodiment of the rotary device for continuous output of large torque for open-pit drilling rig provided by the present invention, please refer to Figures 1 to 4 The rotary device for continuous output of large torque of open-pit drilling rig also includes a housing 7, which is connected to the open-pit drilling rig slide, and two groups of rotary oil cylinders 1 are respectively connected to the two ends of the housing 7, and the power output end of the rotary oil cylinder 1 is inserted into the housing 7; a closed chamber 8 is formed inside the housing 7, and the reciprocating piston 2 is slidably arranged in the closed chamber 8, and the reciprocating direction of the reciprocating piston 2 is along the direction of the connection line of the power output ends of the two groups of rotary oil cylinders 1; the transmission gear assembly 4 and the main shaft 5 are both rotatably connected to the housing 7. The housing 7 plays a role in facilitating the installation of the rotary oil cylinder 1, the reciprocating piston 2, the control console 3, the two groups of transmission gear assemblies 4 and the main shaft 5, and can provide space and power for the reciprocating movement of the reciprocating piston 2. By forming the closed chamber 8 inside the housing 7, the reciprocating piston 2 can be reciprocated, and then the two groups of rotary oil cylinders 1 alternately drive the two groups of transmission gear assemblies 4 to operate.

[0024] One side of the outer wall of the housing 7 is connected to the slide, and the two groups of rotating oil cylinders 1 are located at both ends of the housing 7. The rotating oil cylinders 1 are respectively located on the left and right sides of the closed chamber 8. The control console 3 is connected to the closed chamber 8 to realize filling and extracting hydraulic oil into the closed chamber 8, thereby realizing the action of driving the reciprocating piston 2 to form a reciprocating movement. When the reciprocating piston 2 moves to one side, its driving gear 6 will be meshed and connected with the power output end of the rotating oil cylinder 1, so that the power of the rotating oil cylinder 1 can drive the driving gear 6 to rotate, and then drive a group of transmission gear components 4 to rotate, and finally drive the main shaft 5 to rotate, and output power with a large torque. When the rotation of the rotating oil cylinder 1 on this side reaches its set rotation angle, the rotating oil cylinder 1 on this side stops rotating at this time, and the reciprocating piston 2 is immediately driven to move to its other end, so that the driving gear 6 at the other end of the reciprocating piston 2 can mesh and drive with the rotating oil cylinder 1 on the other side, and the power output of the rotating oil cylinder 1 on this side can drive another group of transmission gear components 4 to rotate, and finally drive the main shaft 5 to rotate, and output power with a large torque. When the rotation of the rotary cylinder 1 on that side reaches its set rotation angle, the rotation of the rotary cylinder 1 on that side is stopped, and the reciprocating piston 2 is immediately driven to move to its other end. Then, the driving gear 6 at the other end of the reciprocating piston 2 can mesh with the rotary cylinder 1 on the other side. The two groups of rotary cylinders 1 are repeatedly moved in this way, so that the two groups of rotary cylinders 1 output power alternately, so that the main shaft 5 continuously outputs power with a large torque, providing the open-pit drilling rig with a large torque output power for construction.

[0025] As a specific embodiment of the rotary device for continuous output of large torque for open-pit drilling rig provided by the present invention, please refer to Figures 1 to 4The control console 3 includes a hydraulic pump station 33, multiple hydraulic pipelines, two groups of rotary cylinder solenoid valves 31, two groups of reciprocating piston solenoid valves 32 and an encoder. One end of the multiple hydraulic pipelines is connected to the hydraulic pump station 33, and the other end is connected to the two groups of rotary cylinders 1 and the closed chamber 8 respectively. The hydraulic pipeline is used to pump hydraulic oil into the rotary cylinder 1 and the closed chamber 8; the two groups of rotary cylinder solenoid valves 31 (respectively the left end rotary cylinder solenoid valve and the right end rotary cylinder solenoid valve) are respectively connected to the hydraulic pipelines between the hydraulic pump station 33 and the rotary cylinder 1, and the rotary cylinder solenoid valve 31 is used to control the rotation and stop of the rotary cylinder 1; the two groups of reciprocating piston solenoid valves 32 are respectively connected to the hydraulic pipelines between the hydraulic pump station 33 and the closed chamber 8, and the reciprocating piston solenoid valve 32 is used to control the reciprocating movement of the reciprocating piston 2; the encoders are electrically connected to the two groups of rotary cylinder solenoid valves 31 and the two groups of reciprocating piston solenoid valves 32, and control the operation respectively to drive the main shaft 5 to rotate continuously with large torque. The hydraulic pump station 33 provides hydraulic power oil, which can drive the reciprocating piston 2 to reciprocate and drive the two sets of rotary cylinders 1 to rotate. The encoder can control the actions of the two sets of rotary cylinder solenoid valves 31 and the two sets of reciprocating piston solenoid valves 32, so that the two sets of rotary cylinders 1 can alternately drive the main shaft 5 to rotate, achieving a large torque output. The hydraulic oil of the hydraulic pump station 33 flows to the closed chamber 8 and the rotary cylinder 1 through the hydraulic pipeline.

[0026] The reciprocating movement or motion of the reciprocating piston 2 is realized by controlling two sets of reciprocating piston solenoid valves 32. The signal of the movement of the reciprocating piston 2 is controlled by the signal sent by the encoder. When the rotation angle of the rotary cylinder 1 on one side is rotated to the angle set for starting the reciprocating piston 2, the rotary cylinder solenoid valve 31 on this side loses power and returns to the middle position. At the same time, the reverse reciprocating piston solenoid valve 32 that controls the movement of the reciprocating piston 2 is energized, and the hydraulic oil immediately pushes the reciprocating piston 2 and the drive gear 6 to the other side. At the same time, after the rotary cylinder solenoid valve 31 on the other side is energized, the rotary cylinder 1 starts to drive the reciprocating piston 2 and the drive gear 6 to the other side. At the same time, after the rotary cylinder solenoid valve 31 on the other side is energized, the rotary cylinder 1 starts to drive the drive gear on this side of the reciprocating piston 2. 6 starts to rotate, and finally continues to rotate in the same direction after multiple stages of deceleration. Similarly, when the rotation angle of the rotary cylinder 1 on this side reaches the set angle, the rotary cylinder solenoid valve 31 on this side loses power and returns to the middle position. At the same time, the reverse reciprocating piston solenoid valve 32 that controls the movement of the reciprocating piston 2 is energized and quickly acts, pushing the driving gear 6 to quickly mesh with the rotary cylinder 1 on the other side and the transmission gear assembly 4 and start rotating. In short, the alternating reciprocating motion of the rotary cylinder 1 and the reciprocating piston 2 enables the present invention to achieve continuous rotation. In this process, after the rotary cylinder 1 rotates to its full position, it is controlled by the rotary cylinder solenoid valve 31 to complete the return stroke, preparing for the next rotation.

[0027] As a specific embodiment of the rotary device for continuous output of large torque for open-pit drilling rig provided by the present invention, please refer to Figures 1 to 4 The transmission gear assembly 4 includes an intermediate gear 41 and a terminal gear 42. The intermediate gear 41 is divided into two groups, which are respectively rotatably connected to the housing 7 and located on both sides of the main shaft 5. The two groups of intermediate gears 41 are alternately meshed and connected to the two groups of transmission gear assemblies 4; the terminal gear 42 is divided into two groups, which are respectively rotatably connected to the housing 7 and located on both sides of the main shaft 5. The two groups of terminal gears 42 are respectively meshed and connected to the two groups of intermediate gears 41, and the two groups of terminal gears 42 are meshed and connected to the main shaft 5. The intermediate gear 41 is equivalent to the role of transmitting power, and also plays the role of deceleration. When the power is output to the main shaft 5, it is a kind of deceleration and large torque output.

[0028] As a specific embodiment of the rotary device for continuous output of large torque for open-pit drilling rig provided by the present invention, please refer to Figures 1 to 4 , half shafts 43 are respectively arranged on both sides of the main shaft 5 inside the housing 7, and two groups of terminal gears 42 are respectively sleeved on the two groups of half shafts 43, and a small bevel gear 44 is arranged on one end of the half shaft 43 close to the main shaft 5, and a large bevel gear 45 is sleeved on the main shaft 5, and the two groups of small bevel gears 44 are meshed and connected with the large bevel gear 45. A plurality of bearings 46 are installed inside the housing 7, and the half shaft 43 is sleeved in the bearing 46 to realize circumferential rotation, and the small bevel gear 44 is provided at one end of the half shaft 43, and the terminal gear 42 is meshed with the intermediate gear 41 to realize deceleration, and the meshing transmission of the small bevel gear 44 and the large bevel gear 45 also realizes deceleration transmission, so that the main shaft 5 can output power at a low speed and with a large torque.

[0029] In order to realize the reasonable layout of the rotating device on the open-pit drilling rig and reduce the space occupation, as a specific implementation of the rotating device with large torque continuous output for the open-pit drilling rig provided by the present invention, please refer to Figures 1 to 4 The half shaft 43 is arranged axially perpendicular to the main shaft 5, the main shaft 5 is arranged through the housing 7, and the large bevel gear 45 is located inside the housing 7. At least one end of the main shaft 5 extends out of the housing 7, and can be connected with a drilling tool, etc., so that the rotation of the drilling tool is driven by the main shaft 5. Moreover, this arrangement does not occupy space on the open-pit drilling rig, and can also drill large-diameter holes to achieve ultra-large torque power output.

[0030] As a specific embodiment of the rotary device for continuous output of large torque for open-pit drilling rig provided by the present invention, please refer to Figures 1 to 4The power output end of the rotary cylinder 1 is an output shaft, and the outer wall of the output shaft is provided with external splines along its circumference. The left half of the inner wall of the two sets of driving gears 6 is sleeved on the two ends of the reciprocating piston 2, and the inner circumference of the right half of the inner wall is provided with internal splines. The internal splines and the external splines match each other to engage or separate. The spline connection method is relatively stable, and the mutual engagement and separation operation is relatively smooth, which can adapt to the output of large torque power.

[0031] The present invention realizes orderly intermittent reciprocating motion under the control of two sets of rotary cylinder solenoid valves 31 and two sets of reciprocating piston solenoid valves 32, and realizes continuous rotation of the power spindle 5 and transmission of large torque through multi-stage transmission. The specific action process is as follows: When the rotary cylinder solenoid valve 31 receives the forward rotation instruction from the control console 3, the rotary cylinder 1 and the drive gear 6 installed on the reciprocating piston 2 (at this time, the inner spline of the drive gear 6 has been meshed with the outer spline of the rotary cylinder 1) start to rotate and transmit power to the intermediate gear 41, the terminal gear 42, the small bevel gear 44 and the large bevel gear 45 in sequence, and finally output power through the main shaft 5 to complete a rotation cycle. The size of this rotation angle is detected by the encoder installed at the bottom of the rotary cylinder 1. When the rotation angle of this rotary cylinder 1 reaches the designed angle, the encoder signal triggers the rotary cylinder solenoid valve 31 to return to the middle position, and the rotary cylinder 1 stops rotating. At the same time, the reciprocating piston solenoid valve 32 on this side is triggered to act, so that the piston pushes the drive gear 6 on the other side and the rotary cylinder 1 on the other side to engage and transmit, and at the same time, the rotary cylinder solenoid valve 31 on this side is triggered to act, and the hydraulic oil pushes the rotary cylinder 1 and the reciprocating piston 2 to move and complete the rotation. When the rotation angle of the rotary cylinder 1 on this side reaches the designed angle, the encoder signal triggers the rotary cylinder solenoid valve 31 on this side to return to the middle position, and the rotary cylinder 1 stops rotating. At the same time, the reciprocating piston solenoid valve 32 is triggered to act, so that the piston pushes the driving gear 6 on the other side and the rotating cylinder 1 on the other side to engage in transmission. The main shaft 5 is rotated continuously with large torque through repeated switching of the rotating cylinder solenoid valve 31 and the reciprocating piston solenoid valve 32 and the alternating movement of the rotating cylinder 1 and the reciprocating piston 2.

The through hole 47 is provided at the center of the intermediate gear 41 and passes through the intermediate gear 41 along its axial direction. By injecting lubricating oil into the through hole 47, the lubricating oil can gradually flow toward the main shaft 5, thereby achieving the effect of lubricating the main shaft 5.

[0033] As a specific embodiment of the rotary device for continuous output of large torque for open-pit drilling rig provided by the present invention, please refer to Figures 1 to 4The housing 7 has a plurality of oil injection holes 71 connected to the closed chamber 8. A plurality of hydraulic pipelines are connected to the plurality of oil injection holes 71, and are used to inject and extract hydraulic oil into and out of the closed chamber 8, respectively, so as to drive the reciprocating piston 2 to reciprocate inside the closed chamber 8. The oil injection holes 71 are used to facilitate the injection of hydraulic oil into the closed chamber 8, so as to drive the reciprocating piston 2 to reciprocate, and the hydraulic pipelines and the oil injection holes 71 are sealed.
