Description

TECHNICAL FIELD

[0001] The utility model relates to rock drilling equipment technical field, concretely is a rock drilling machine pipeline system and rock drilling machine. BACKGROUND

[0002] In the tunnel or mine support engineering, most of the trolley provides high pressure air for itself through the air compressor and the gas tank on the vehicle. The rock drilling machine is an important component of the rock drilling trolley. Generally, the rock drilling machine has a high-pressure water cleaning drilling function. In addition, the rock drilling machine needs to be continuously blown with oil mist during work to ensure the lubrication of the internal moving parts. Generally, the high-pressure cleaning water is opened simultaneously with the impact of the rock drilling machine. If the cleaning water is opened slightly slowly, the water outlet hole at the drill bit will be blocked by the stone slag, the cleaning water cannot be discharged, and the stone slag in the drill hole will cause the drill to be stuck. In addition, the internal parts of the rock drilling machine need to be lubricated with pneumatic lubricating oil. If the rock drilling machine does not continuously spray oil mist into the interior during impact, the parts between the parts will accelerate wear and overheating, and the parts will be abnormally damaged, which will cause serious economic losses and delay of construction period.

[0003] There is gaseous water in the air, which will form liquid water after being compressed and accumulate in the gas tank. The gas tank is equipped with a manual blowdown drain valve, which needs to be manually opened by workers. Many times, the water in the gas tank is not discharged in time, and the water will occupy the space in the gas tank, causing the capacity of the gas tank to be reduced. In addition, water will flow into the lower-level elements. For example, after the water enters the oil mist lubrication system, due to the structure of the rock drilling machine, the water and hydraulic oil will come into contact. Under the high-speed movement of the parts, the hydraulic oil will quickly emulsify, causing the system performance to decline, and even causing damage to critical components such as rock drilling machines and hydraulic pumps, resulting in significant economic losses. In addition, there is a lot of dust in the mine, which easily enters the pneumatic system, causing the electromagnetic air valve to be stuck and damaged. During the daily construction process, if the operator does not maintain the system properly and does not discharge the water in the gas tank in time, once this situation occurs, most of the water will enter the lower-level components, causing damage to the components and leading to a decline in the performance of the rock drilling machine system and a delay in the construction period.

The gas valve 1 in the embodiment is an electromagnetic gas valve, which is used for controlling the on-off of the fourth pipeline 7. When the fourth pipeline 7 is turned on, the clean gas output by the filter assembly enters the gas-controlled water valve 2 through the second output end and the fourth pipeline 7, so that the gas-controlled water valve 2 is opened, and then the clean water in the water supply assembly enters the cleaning circuit of the rock drill 19, so that the drilling hole is cleaned during the drilling process. In this process, the pipeline on-off of the water pump is controlled by using the clean gas after filtration, thereby reducing the risk of jamming of the gas-controlled water valve 2 and the gas valve 1.

The output end of the air compressor 8 is connected with the input end of the air tank 9 through the fifth pipeline 10. The output end of the air tank 9 is connected with the input end of the filter assembly through the first pipeline 4. The fifth pipeline 10 is provided with a one-way valve 11 and a pressure gauge 12. The one-way valve 11 and the pressure gauge 12 are connected with the fifth pipeline 10 through a three-way pipe respectively. The one-way valve 11 is used for protecting the air compressor 8. The pressure gauge 12 is used for reading the air pressure.

[0045] As a preferred implementation manner, the height of the air tank 9 is lower than the air compressor 8 and the filter assembly. The input end and the output end of the air tank 9 are located at the top. Thus, the liquid water and impurities can be effectively prevented from entering the lower elements such as the filter assembly and the oil atomizer 3. Further preferably, the bottom of the air tank 9 is connected with a first automatic drainage valve 13 through a thread or a pipeline.

[0047] In the embodiment, the filter 14 adopts the configuration shown in Figure 2 The filter 14 adopts the configuration shown in Figure 2 The filter 14 adopts the configuration shown in

[0048] As a preferred implementation manner, along the direction from the input end to the first output end of the filter assembly, the filtering accuracy of each filter 14 increases in turn. For example, the filter assembly shown in Figure 1 The filter assembly shown in

[0049] As a preferred embodiment, the bottom of the filter 14 is provided with a second automatic drainage valve 15, so that the water accumulated in the filter 14 can be continuously drained during the construction process without human intervention.

[0050] It is worth noting that the first automatic drainage valve 13 and the second automatic drainage valve 15 in the embodiment can be mechanical valves with a floating ball, or can be realized by using an electrically controlled electromagnetic valve.

[0051] As a preferred embodiment, the drill pipe system further comprises a pressure sensor 16 and an electromagnetic hydraulic valve 17. The pressure sensor 16 is connected to the first pipe 4 through a tee joint, the input end of the electromagnetic hydraulic valve 17 is connected to an external hydraulic system, the output end of the electromagnetic hydraulic valve 17 is connected to the hydraulic oil inlet of the drill 19, and the pressure sensor 16 and the electromagnetic hydraulic valve 17 are electrically connected through a host computer such as a PLC, so that when the air pressure is lower than the required oil mist air pressure of the drill 19, the drill 19 cannot be impacted to avoid dry grinding of the drill 19 structure when there is no oil mist lubrication, and premature wear. For example, the drill 19 requires an oil mist air pressure of 2 bar, and when the pressure sensor 16 measures that the air pressure is lower than 2 bar, the PLC sends a command to close the electromagnetic hydraulic valve 17 according to the preset logic. As for the automatic opening and closing of the electromagnetic hydraulic valve 17 controlled by the PLC according to the pressure signal, it is a conventional technical means in the art, and the embodiment will not be described in detail.

[0052] In the specific implementation process, the second pipe 5 is provided with a pressure reducing valve 18, so as to avoid excessive air pressure.
