For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the following description will be made by way of specific embodiments with reference to the accompanying drawings.
Referring to fig. 2 and fig. 3 together, a rod storage warehouse of a drilling machine according to an embodiment of the present invention includes: the rod magazine 10, upper support 20, lower support 30, actuator 40, angle sensor 50, control valve 60, and controller (not shown).
Wherein, both ends of the rod storage bin 10 are respectively connected with the upper supporting device 20 and the lower supporting device 30 in a rotating way.
The actuating mechanism 40 is arranged on the upper supporting device 20, the output end of the actuating mechanism is connected with the rod storage bin 10 through a pin shaft, and the input end of the actuating mechanism is connected with the control valve 60.
An angle sensor 50 is provided on the lower support device 30 and is communicatively connected to the controller.
The control valve 60 is also electrically connected to the controller.
During operation, the controller monitors a preset rotation direction signal and an angle value fed back by the angle sensor 50, controls the control valve 60 to switch to a preset valve position corresponding to the preset rotation direction signal according to the monitored preset rotation direction signal, and the actuating mechanism 40 drives the rod storage bin 10 to rotate forward or backward according to the preset valve position; when the angle value indicates that the rod storage bin 10 rotates to a preset stopping angle, the controller controls the control valve 60 to switch to a stopping valve position, and the actuator 40 stops rotating the rod storage bin 10 according to the stopping valve position.
According to the embodiment of the invention, the two ends of the rod storage bin are respectively connected with the upper supporting device and the lower supporting device in a rotating way, and the switching of the drill rods can be realized through the rotation of the rod storage bin. The actuating mechanism is arranged on the upper supporting device, the output end of the actuating mechanism is connected with the rod storage bin through a pin shaft, the input end of the actuating mechanism is connected with the control valve, the angle sensor is arranged on the lower supporting device and is in communication connection with the controller, the control valve is further electrically connected with the controller, and can enable the controller to monitor a preset rotation direction signal and an angle value fed back by the angle sensor during operation so as to control the control valve to switch to a preset valve position corresponding to the preset rotation direction signal according to the monitored preset rotation direction signal, further enable the actuating mechanism to drive the rod storage bin to rotate forward or reverse according to the preset valve position, and enable the controller to control the control valve to switch to a stop valve position when the angle value indicates the rod storage bin to rotate to a preset stop angle, and further enable the actuating mechanism to enable the rod storage bin to stop rotating according to the stop valve position. Furthermore, the actuating mechanism and the angle sensor can be used for replacing an oil cylinder-connecting rod mechanism in the existing rod storage device, the structure is simplified, and the rod storage warehouse of the drilling machine only needs to operate according to a preset rotation direction signal and an angle value fed back by the angle sensor when rotating, so that related operation of the oil cylinder is not needed, the operation steps are reduced, the time is saved, the possibility of error in the operation process is reduced, and the operation efficiency of the drilling machine is improved.
Optionally, the preset rotation direction signal may include a forward rotation signal and a reverse rotation signal; the preset valve positions may include a forward valve position and a reverse valve position.
The controller may control the control valve 60 to switch to a preset valve position corresponding to the preset rotation direction signal according to the monitored preset rotation direction signal, and may include:
the controller controls the control valve 60 to switch to the forward valve position according to the forward signal.
Alternatively, the controller controls the control valve 60 to switch to the reverse valve position in accordance with the reverse signal.
In this embodiment, the rotation direction of the rod storage bin 10 can be selected through the electric control handle, corresponding actions are executed through the controller, the control valve 60 and the actuating mechanism 40, and the angle value of the rod storage bin 10 is detected through the angle sensor 50, so that whether the rod storage bin 10 rotates in place is determined.
By way of example, the electric control handle can select forward rotation or reverse rotation, so that the controller can monitor a corresponding preset rotation direction signal of forward rotation or reverse rotation. When the electric control handle selects forward rotation, namely, the controller monitors a forward rotation signal, the controller controls the control valve 60 to switch to a forward rotation valve position according to the forward rotation signal, and the executing mechanism 40 drives the rod storage bin 10 to forward rotate according to the forward rotation valve position of the control valve 60. When the controller monitors the forward rotation signal and the angle value detected by the angle sensor indicates that the rod storage bin is rotated into position (i.e., rotated to a preset stopping angle), the controller controls the control valve 60 to switch to the stopping valve position, and the actuator 40 stops the rotation of the rod storage bin 10 according to the stopping valve position of the control valve 60. When the electric control handle is selectively reversed, that is, the controller monitors a reversing signal, the controller controls the control valve 60 to switch to a reversing valve position according to the reversing signal, and the actuating mechanism 40 drives the rod storage bin 10 to reverse according to the reversing valve position of the control valve 60.
Optionally, the controller may be further configured to monitor a preset stall signal; when the preset stall signal is detected and the angle value indicates that the rod storage bin 10 does not rotate to the preset stall angle, the controller controls the control valve 60 to switch to a stop valve position, and the execution mechanism 40 stops rotating the rod storage bin 10 according to the stop valve position.
In this embodiment, when the rod storage of the drilling machine fails or needs to stop, the electric control handle may also select the middle position (i.e. select to stop), at this time, the controller monitors a preset stop signal, and if the angle value received by the controller at this time indicates that the rod storage 10 does not rotate to the preset stop angle, the controller may control the control valve 60 to switch to the stop valve position, so that the rotation of the rod storage 10 may be suspended. If the drill rod storage bin is out of order or can continue to rotate, the electric control handle can select the forward rotation again, so that the controller can continue to rotate the rod storage bin 10 from the place where the controller is interrupted last time until the rod storage bin 10 reaches a preset stopping angle. If the fault of the drill rod storage warehouse is not removed or needs to be reset, the drill rod storage warehouse can be selectively reversed through the electric control handle so as to reset to the position before interruption.
Wherein, store the pole storehouse 10 can store many drilling rods according to actual need, every drilling rod can correspond a preset stall angle in storing the pole storehouse 10. Taking the example that the rod storage bin 10 stores 5 rods as an example, the initial angle (i.e., the preset stall angle) corresponding to the first rod is set to 10 °, and the two adjacent rods are different by 50 °, the preset stall angle corresponding to each rod in the rod storage bin 10 may be as shown in table 2.
TABLE 2
It should be noted that, the initial angle corresponding to the first drill rod and the angle difference between two adjacent drill rods may be set according to actual needs, which is not limited in this embodiment.
Taking a phase difference of 50 ° between two adjacent drill rods as an example, in this embodiment, considering that there is a certain hysteresis of the hydraulic driving actuator 40, an error exists in the angle of each rotation, which may not be exactly 50 °, for example, may be 50.5 ° or 49 °, etc., so that the preset stall angle corresponding to the required drill rod is directly determined, whether the rod storage bin 10 rotates to the preset stall angle is determined according to the angle value fed back by the angle sensor 50, and when the angle value fed back by the angle sensor 50 does not reach the corresponding preset stall angle, the controller is combined to monitor the preset stall signal or the preset rotation direction signal, so as to control the rod storage bin 10 to stop rotating or continue rotating. When the angle value fed back by the angle sensor 50 reaches the corresponding preset stopping angle, the controller controls the control valve 60 to switch to the stopping valve position, so that the actuating mechanism 40 controls the rod storage bin 10 to stop rotating under the control of the stopping valve position. Instead of recording the starting angle at each rotation of the rod storage bin 10, the controller determines whether the rod storage bin 10 stops rotating based on the starting angle and the angle difference between two adjacent rods, thereby avoiding error accumulation.
Optionally, before operation, the controller may be further configured to:
whether the angle sensor 50 is broken or shorted is detected, if the angle sensor 50 is broken or shorted, a prompt signal is sent to indicate that the angle sensor 50 is faulty, and if the angle sensor 50 is not broken or shorted, a preset rotation direction signal is waited to be received.
In this embodiment, before the rod storage of the drilling machine works, the controller detects whether the angle sensor 50 breaks a line or short-circuits, so as to avoid the influence of the angle sensor 50 fault on the work.

In this embodiment, the actuator 40 may have a braking function, for example, the actuator 40 is a combination of a hydraulic motor 41 and a turbine reduction mechanism 42. By using the combination of the hydraulic motor 41 and the turbine reduction mechanism 42 as the actuating mechanism 40, the influence of the hydraulic motor 41 on the rod storage bin 10 can be reduced by using the transmission ratio of the turbine reduction mechanism 42, and even if a control valve for driving the hydraulic motor 41 has an untimely response, the rotating deviation of the hydraulic motor 41 can be reduced to the minimum through the transmission ratio of the turbine reduction mechanism 42, and the rod storage bin 10 can be quickly stopped rotating by virtue of the self-locking function of the turbine reduction mechanism 42 when the hydraulic motor 41 is stopped, so that accurate angle switching is realized.
