[0048] refer to Figure 1 , the present application proposes a hydraulically controlled lubrication system for a raise drilling rig, the hydraulically controlled lubrication system for a raise drilling rig comprising: a first gear pump 100, a flow control valve group 200, a gear motor 300, a second gear pump 400 and a flow diversion structure 500;
[0049] The first gear pump 100 is connected in series to the motor pump unit of the raise drilling rig;
[0050] The flow control valve group 200 has a valve group oil inlet and a lubrication oil outlet, and the valve group oil inlet is connected in series with the first gear pump 100;
[0051] The gear motor 300 has an oil inlet connected to the lubrication oil outlet;
[0052] The oil inlet of the second gear pump 400 is connected to the oil storage structure at the bottom of the reduction box; the gear motor 300 is used to drive the second gear pump 400 to operate;
[0053] The flow splitting structure 500 is used to receive the gear oil from the oil outlet of the second gear pump 400 and split the oil to output to the bearing lubrication port.
[0054] The first gear pump 100 is connected in series to the motor pump group of the skydrilling rig, and the motor pump group can be directly used as the power output. The first gear pump 100 can directly pump hydraulic oil into the flow control valve group 200, and the hydraulic oil is high-pressure hydraulic oil. The motor pump group is the original motor pump group in the entire system of the skydrilling rig, for example, the main motor pump group that drives the skydrilling rig to operate and propel can be used. The first gear pump 100 can pump hydraulic oil from the main oil tank.
[0055] The oil inlet of the gear motor 300 is connected to the lubrication oil outlet, and the hydraulic oil input to the gear motor 300 can be discharged to the motor housing of the rotary motor of the skydrill through the oil discharge port of the gear motor 300 for cleaning and cooling of the rotary motor.
[0056] The high-pressure hydraulic oil flows through the flow control valve and is then input into the gear motor 300, thereby driving the gear motor 300 to rotate. The gear motor 300 can further drive the second gear pump 400 to rotate. The second gear pump 400 pumps the gear oil from the oil storage structure at the bottom of the reduction box, and then transmits the gear oil to the bearing lubrication port through the diversion structure 500. There are many parts in the gearbox bearing that need to be lubricated, and usually there are multiple bearing lubrication ports, and the gear oil can be diverted to different bearing lubrication ports through the diversion structure 500. The oil storage structure at the bottom of the reduction box has many forms, which can be a self-designed oil storage structure or the original oil pan at the bottom of the gearbox.
[0057] The hydraulic lubrication system of the skydrilling rig in the embodiment of the present application adopts a pure hydraulic drive structure, which can provide a great driving force compared to the electric drive structure, ensuring that the gear oil can be flushed to each part that needs lubrication, and because it adopts a pure hydraulic drive structure, there is no need to worry about being affected by water vapor in a humid environment, which improves the ability to apply to the environment. In addition, the hydraulic lubrication system of the skydrilling rig in the embodiment of the present application fully utilizes the original motor pump group in the skydrilling rig, and no additional motor is required, effectively controlling the overall cost.
[0058] In some embodiments, the flow diversion structure 500 may adopt a flow diversion block or other valve components with flow diversion capability.
[0059] In some embodiments, reference Figure 1 , the hydraulic lubrication system of the raise drilling rig also includes:
[0060] The filter 600 is connected between the oil outlet of the second gear pump 400 and the flow dividing structure 500 .
[0061] The filter 600 can be used to filter iron filings, slag, etc. in the gear oil to prevent the gear oil from causing damage to the parts that need to be lubricated.
[0062] In some embodiments, reference Figure 1 , the hydraulic lubrication system of the raise drilling rig also includes:
[0063] The water cooler 700 is disposed between the oil outlet of the filter 600 and the flow diversion structure 500 .
[0064] The water cooler 700 can cool the gear oil. The cooled gear oil can take away a certain amount of heat in the parts that need to be lubricated, making the overall operation of the gear box more stable.
[0065] In some embodiments, reference Figure 1 , the hydraulic lubrication system of the raise drilling rig also includes:
[0066] The first overflow valve 800 is connected between the oil outlet of the second gear pump 400 and the oil storage structure at the bottom of the reduction box.
[0067] The overflow valve has overflow capability. When the outlet pressure of the second gear pump 400 is greater than the preset pressure value due to blockage or other reasons, the first overflow valve 800 will begin to overflow and release the gear oil to the oil storage structure at the bottom of the reduction box.
[0068] In some embodiments, reference Figure 1 , the hydraulic lubrication system of the raise drilling rig also includes:
[0069] The one-way valve 900 is connected between the first gear pump 100 and the oil inlet of the valve group.
[0070] The one-way valve 900 allows flow in only one direction, thereby protecting the first gear pump 100 .
[0071] In some embodiments, reference Figure 1 The flow control valve group 200 also has at least one auxiliary oil outlet. The auxiliary oil outlet can be used for auxiliary oil supply. For example, oil can be supplied to other actuators through the auxiliary oil supply port, or oil can be supplied to the rotary Marfa housing through the auxiliary oil supply port. The specific work to be performed by using the auxiliary oil supply port is not specifically limited in this application.
[0072] In some embodiments, reference Figure 1 The auxiliary oil outlet includes an overflow oil port, which is connected to the housing of the rotary motor. The overflow oil port can achieve overflow, and can remove the pressure higher than that required by the lubrication system to avoid damage to the hydraulic pipeline caused by high pressure.

After the high-pressure hydraulic oil entering the flow control valve group 200 is regulated by the manual speed regulating valve 210, a path of oil with appropriate pressure and flow is separated and supplied to the gear motor 300; after the high-pressure hydraulic oil passes through the pressure reducing valve 220, a path of oil with fixed pressure and appropriate flow is separated and supplied to an actuator; after the high-pressure hydraulic oil passes through the relief valve, the hydraulic oil supplied by the first gear pump 100 that exceeds the pressure required by the lubrication system is discharged and flows into the rotary motor housing through the T port.
[0075] In some embodiments, reference Figure 3 , Figure 4 The flow control valve group 200 is arranged at the bottom of the reduction box through the first mounting member 201. The first mounting member 201 can be a mounting plate, and a bolt through hole is provided on the mounting plate, so that the first mounting member 201 can be fixed to the bottom of the reduction box through the bolt through hole.
[0076] In some embodiments, reference Figure 5 , Figure 6 The gear motor 300 drives the second gear pump 400 to operate through the coupling. The coupling can play a transmission role and can better transmit the output power of the gear motor 300 to the second gear pump 400.
[0077] In some embodiments, reference Figure 5 , Figure 6 The gear motor 300 is arranged at the bottom of the reduction box through the second mounting member 301. The second mounting member 301 can also be a mounting plate, and a bolt through hole is provided on the mounting plate, so that the second mounting member 301 can be fixed to the bottom of the reduction box through the bolt through hole. In addition, when the second mounting member 301 is installed, a bell cover can be used to assist in protection.
[0078] In some embodiments, reference Figure 7 The water cooler 700 can be fixedly installed by the third mounting member 701. The third mounting member 701 can also be a mounting plate, and a bolt through hole is provided on the mounting plate, so that the third mounting member 701 can be fixed on a fixed position such as a reduction box through the bolt through hole.
