In the rock drilling construction process, the rock drill needs deslagging, heat dissipation and lubrication. These functions require the cooperation of the integrated water circuit system, the air circuit system and the lubrication system to ensure the normal use of the rock drill.
Specifically, on one hand, different cleaning modes have different effects due to different rock stratum conditions. For example, in the case of poor rock conditions, such as direct use of water in mudstones for cleaning, too small an amount of water can cause water and soil to mix, resulting in mud water accumulation and plugging the hole site, resulting in difficulty in loading, too large an amount of water can damage surrounding rocks, resulting in hole collapse, and even in face collapse. Under the harder circumstances of stratum environment, if use the gas circuit direct cleaning, then because the cleaning performance of gas circuit is relatively poor in the water route washs, thereby probably can lead to because the sediment is not smooth to block the boring, increase consumptive material loss.
Besides the disadvantage of poor cleaning effect, the air path slag discharge has to be configured with air cooling heat dissipation and consider dust removal treatment.
On the other hand, if the lubrication system of the rock drill fails, such as oil shortage, insufficient oil mist pressure or low oil mist pressure of the lubrication system of the rock drill equipment, the rock drill is damaged due to the fact that lubrication is not available, lubrication is insufficient or a sealing element is damaged.
Therefore, when the normal operation of the rock drilling equipment is ensured, the response is timely made when the water path system, the air path system and the lubrication system are in failure, and the rock drilling bit is prevented from being frequently clamped.

However, the fault of the rock drill is not reliable only by visual observation of a machine hand and a cooperator and experience judgment, and correct coping operation cannot be made in time according to the fault state, so that the equipment safety of the rock drill cannot be ensured, and the consumable loss and the equipment damage probability are increased.
Based on the above problems, the present application provides a control method of a rock drill, which is applied to a control module of a rock drill device, the rock drill device further comprises a waterway module, a gas circuit module, a lubrication module and a rock drilling assembly, the control module controls a waterway detection unit of the waterway module to detect water inflow and water inflow pressure of the waterway module through the waterway module, controls a gas circuit detection unit of the gas circuit module to detect gas storage tank air pressure of the gas circuit module through the gas circuit module, controls a lubrication detection unit of the lubrication module to detect liquid level and oil pressure of an oil storage tank of the lubrication module through the lubrication module, determines a current running state according to preset thresholds corresponding to each parameter, and determines whether to start the rock drilling assembly according to the current running state, if yes, controls the rock drilling assembly to start and run. By the method, whether the waterway module, the gas circuit module and the oil circuit module fail or not can be detected in real time before the rock drill equipment is started and in the running process, so that the equipment safety of the rock drill is ensured, and the consumable loss and the equipment damage probability are reduced.

It should be noted that, the control module may be connected to the communication end of the waterway module, the communication end of the air path module, and the communication end of the lubrication module by way of control lines, or may be connected to the communication end of the waterway module, the communication end of the air path module, and the communication end of the lubrication module by way of wireless methods, such as bluetooth connection. Optionally, the control module may receive a control instruction of a control person, where the instruction includes: the device comprises a starting waterway module, a stopping waterway module, a starting air circuit module, a stopping air circuit module, a starting lubrication module and a stopping lubrication module. The starting and stopping waterway module can be used for controlling the input of an external water source and the starting and stopping of the detecting unit and the executing unit in the waterway module, the starting and stopping waterway module can be used for controlling the input of external air and the starting and stopping of the detecting unit and the executing unit in the waterway module, and the starting and stopping lubrication module can be used for controlling whether the oil storage tank outputs lubricating oil or not.
As an alternative embodiment, the water outlet end and the air outlet end of the water channel module and the air channel module may be led into the tail of the drilling assembly as the same pipe, so as to clean the drilling bit.

For example, the reservoir pressure may be measured by a pressure gauge.

In this embodiment, the water inflow rate and the water inflow pressure of the water path module in the rock drill equipment are obtained, so as to determine the first current operation state of the water path module, then the air pressure of the air storage tank of the air path module in the rock drill equipment is obtained, so as to determine the second current operation state of the air path module, then the liquid level and the oil pressure of the oil storage tank of the lubrication module in the rock drill equipment are obtained, so as to determine the third current operation state of the lubrication module, finally, whether to start the rock drill assembly is determined according to the first current operation state, the second current operation state and the third current operation state, and if yes, the rock drill assembly is controlled to start and operate. Through the steps, equipment safety of the rock drill is guaranteed from three dimensions of waterway, gas circuit and lubrication, drill rod clamping is prevented, and consumable loss and equipment damage probability are reduced.
Next, detailed description is made on how the water path module, the air path module and the lubrication module in the above steps determine the current running state in detail respectively:
optionally, in the step S201, a first current operation state of the waterway module is determined according to the inflow and the inflow pressure, specifically:
optionally, the communication end of the waterway module is used for controlling the waterway detection unit in the waterway module to detect the water inflow rate and the water inflow pressure of the waterway module, and determining the first current running state of the waterway module according to the preset water inflow rate threshold value, the preset water inflow pressure threshold value, the water inflow rate of the waterway module and the water inflow pressure of the waterway module, wherein the first current running state is used for indicating whether the waterway module runs normally or not.
