Description

Technical Field

[0001] This application relates to the field of mechanical engineering technology, and in particular to a cooling device for a rock drill test bench. Background Technology

[0002] A rock drill test bench is a device used to test the performance and quality of rock drills. During testing, the rock drill generates a large amount of heat, which can lead to overheating, affecting the accuracy of test results and the lifespan of the equipment. Therefore, the rock drill test bench needs to be cooled to ensure the stability of the testing environment, protect the equipment from heat damage, and obtain reliable test data.

[0003] In existing technologies, rock drill test benches typically employ a water-cooling system. This system includes components such as a water hose reel, filter, water cooler, safety valve, and water pump. The water hose reel connects to an external water source to ensure a continuous water supply; the filter removes impurities from the water, protecting the cooling system; and the water cooler reduces the temperature of the hydraulic oil through heat exchange with the hydraulic system. During drilling tests, cooling water is sprayed onto the drill bit and cutting tool, lowering their temperature, and hot water is discharged from the borehole, effectively controlling the temperature of the test bench and ensuring the normal operation of the equipment and the accuracy of the test results.

[0004] In existing technologies, the utilization rate of cooling water is low. During drilling tests, used cooling water is usually discharged directly from the borehole, lacking an effective water recycling and reuse mechanism, resulting in a large amount of cooling water being wasted after completing its initial function.

[0084] It should be noted that the phrase "at...time" in the embodiments of this application can refer to the instant at which a certain situation occurs, or to a period of time after the occurrence of a certain situation; the embodiments of this application do not specifically limit this. Furthermore, the cooling device for a rock drill test bench provided in the embodiments of this application is merely an example; the cooling device for a rock drill test bench may include more or fewer components.

[0085] To facilitate a clear description of the technical solutions in the embodiments of this application, some terms and technologies involved in the embodiments of this application will be briefly introduced below:

[0086] A rock drill is a tool used to drill holes in hard materials such as rock or concrete. It is commonly used in mining, construction, and geological exploration. It uses mechanical impact and rotational motion to propel the drill bit into the rock, thus achieving efficient drilling operations.

[0087] A rock drill test bench is a device used to evaluate and verify the performance and durability of rock drills. By simulating actual working conditions, the test bench can measure parameters such as impact force, drilling speed, energy consumption, and vibration of the rock drill, ensuring that it meets design specifications and safety standards. This testing helps optimize the design of the rock drill, improving its efficiency and reliability.

[0088] Rock drill test bench cooling system: This system controls the temperature of the equipment during testing, ensuring that the rock drill will not overheat and be affected or damaged under simulated actual working conditions. The system rapidly removes generated heat through circulating coolant or airflow, maintaining the test bench and rock drill within a safe temperature range, thereby ensuring the accuracy of test results and the long-term reliability of the equipment.

[0089] Test bench: A test bench is a structure used to support and secure equipment or components during testing. It is typically made of robust materials to ensure stability and safety during testing. It can accommodate different types and sizes of equipment, helping to precisely position and hold the equipment under specific test conditions, enabling the accurate measurement and evaluation of various performance parameters.

[0090] A punch is a tool component that withstands impact forces during stamping or forging, typically used in dies or stamping equipment. It comes into direct contact with the workpiece, transmitting mechanical pressure to deform or cut the material. Punches need to possess high strength and wear resistance to withstand repeated impacts and friction while maintaining precise shape and dimensions to ensure processing quality and efficiency.

[0091] Drill bits are tools used for rock drilling, hole drilling, or breaking hard materials, typically used in conjunction with rock drills or drilling rigs. They are made of high-strength alloy steel and feature a sharp cutting head and a robust shaft to withstand high impact forces and abrasion. Drill bits are designed in diverse ways to adapt to different geological conditions and operational needs, and are widely used in mining, construction, and geological exploration.

[0092] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0093] The technical solutions of this application will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0094] To clearly understand the technical solution of this application, the existing technology solutions will first be described in detail. In the prior art, the cooling of the rock drill test bench is mainly achieved through a water cooling system, which includes components such as a water hose reel, a filter, a water cooler, a safety valve, and a water pump. The water hose reel is connected to an external water source to ensure a continuous water supply, the filter removes impurities from the water to protect the system, and the water cooler reduces the temperature of the hydraulic oil through heat exchange with the hydraulic system. During the drilling test, cooling water is sprayed onto the drill bit and drill string to reduce the temperature, and hot water is discharged from the borehole, thereby effectively controlling the temperature of the test bench, ensuring the normal operation of the equipment and the accuracy of the test results.

[0095] However, existing rock drill test benches suffer from low cooling water utilization rates. During drilling tests, used cooling water is typically discharged directly from the borehole, lacking an effective water recycling and reuse mechanism. This results in a significant amount of cooling water being wasted after fulfilling its initial function.

[0096] Therefore, addressing the issue of low cooling water utilization in existing rock drill test benches, the research found that a cooling water recycling system can be added to improve its utilization rate: ① A collection tank can be installed on the test bench to collect used cooling water. ② A multi-stage filtration system, including coarse and fine filtration, can be introduced to remove particulate impurities and micro-pollutants from the cooling water, ensuring the water quality meets reusable standards. ③ A high-efficiency heat exchanger can be installed in the circulation system to exchange heat between the collected hot water and the cooling medium, rapidly reducing the water temperature for reuse in the cooling process.

[0097] Specifically, a closed-loop water circulation system can be established, with a collection tank to gather used cooling water and a multi-stage filtration system to remove impurities. A high-efficiency heat exchanger lowers the water temperature, making it suitable for reuse. The entire process is managed by an automated control system that monitors water quality and temperature in real time and adjusts the water circulation speed and filtration frequency to ensure efficient system operation. High-efficiency, energy-saving water pumps maintain a stable water flow, thereby improving cooling water utilization.

[0098] The cooling device of the rock drill test bench in this embodiment of the application transmits cooling water to the drill bit and the punch head through a first water pipe and a second water pipe, directly cooling these high-temperature components locally to ensure they maintain a suitable temperature during testing. The used cooling water is not directly discharged but is further cooled by an air cooler to a temperature suitable for reuse. Subsequently, this cooled water is returned to the water tank, forming a closed-loop recycling system. This design effectively reduces cooling water waste.

[0099] Based on the above-mentioned inventive discovery, the technical solution of this application is proposed.

[0100] The embodiments of this application are described below with reference to the accompanying drawings.

[0101] Figure 1 A schematic diagram of the cooling device for the rock drill test bench provided in this application embodiment. Figure 1 .like Figure 1 As shown, in this embodiment, the cooling device of the rock drill test bench includes: a water tank 100, a water cooler 200, a test bench 300, an air cooler 400, and a hydraulic system 500.

[0102] Specifically, the water tank 100 is a water storage device used to store and circulate cooling water. The water cooler 200 is a cooling device used to reduce the temperature of the hydraulic system 500 to ensure its normal operation. The test bench 300 is a structure for fixing and supporting the rock drill, including the drill bit 302 and the punch head 301, which receive cooling water through water pipes for cooling. The air cooler 400 is an air cooling device used to further reduce the temperature of the cooling water to improve cooling efficiency. The hydraulic system 500 is the power system of the rock drill test bench, responsible for driving the operation of the rock drill, and needs to be connected to the water cooler 200 for cooling to prevent overheating.

[0103] The test bench 300 includes a punch head 301 and a drill bit 302. The drill bit 302 is connected to the punch head 301. The drill bit 302 is provided with a first water guide pipe, and the punch head 301 is provided with a second water guide pipe.

[0104] Specifically, the test bench 300 can mechanically connect the drill bit 302 to the punch head 301. Cooling water flows through the first and second water guide pipes, directly contacting the drill bit 302 and the punch head 301, thereby effectively reducing the heat generated during operation. This design ensures that the rock drill maintains a suitable temperature under high-intensity operation, preventing equipment damage or performance degradation due to overheating.

[0105] The first outlet 101 of the water tank 100 is connected to one end of the water cooler 200, and the other end of the water cooler 200 is connected to one end of the first water guide pipe and one end of the second water guide pipe respectively. The other ends of the first water guide pipe and the second water guide pipe are both connected to the first inlet 102 of the water tank 100.

[0106] Specifically, the first outlet 101 of the water tank 100 is connected to one end of the water cooler 200 via a pipe, and the other end of the water cooler 200 is connected to one end of the first and second water guide pipes via pipes. These two water guide pipes are connected to the drill bit 302 and the punch 301 respectively, for transmitting cooling water. The other ends of the first and second water guide pipes are connected to the first inlet 102 of the water tank 100 via pipes, completing the circulation of cooling water. This design is used to reduce the temperature of the drill bit 302 and the punch 301 by circulating cooling water when the rock drill test bench is working, thereby preventing the equipment from overheating and improving its working efficiency and service life.

[0107] The water cooler 200 is also connected to the hydraulic system 500.

[0108] Specifically, the water cooler 200 is connected to the hydraulic system 500 via pipes or connection interfaces, forming a cooling circuit. This connection allows cooling water to flow through the critical components of the hydraulic system 500, absorbing and carrying away heat generated due to hydraulic operation. By lowering the temperature of the hydraulic system, the water cooler 200 ensures that the hydraulic system remains within a safe operating temperature range under high loads or during prolonged operation. This design prevents the hydraulic system from overheating, thereby improving its reliability and performance and extending the service life of the equipment.

[0109] The second outlet 103 of the water tank 100 is connected to one end of the air cooler 400, and the other end of the air cooler 400 is connected to the first inlet 102 of the water tank 100.

[0110] Specifically, the second outlet 103 of the water tank 100 is connected to one end of the air cooler 400 via a pipe, and the other end of the air cooler 400 is connected back to the first inlet 102 of the water tank 100 via a pipe. This design allows the cooling water in the water tank to circulate through the air cooler, which uses airflow to lower the temperature of the cooling water. In this way, the cooling water is further cooled before returning to the water tank, thereby improving the cooling efficiency of the entire system. This design ensures that the cooling water maintains a low temperature during circulation to effectively cool the various components of the rock drill test stand and prevent the equipment from overheating.

[0111] When the rock drill test stand is in operation, the water cooler 200 is used to cool the hydraulic system 500, the first water pipe and the second water pipe are both used to transmit cooling water to cool the drill bit 302 and the punch 301, and the air cooler 400 is used to cool the cooling water.

[0112] This embodiment provides a cooling device for a rock drill test bench. Cooling water in the water tank flows into a water cooler through a first outlet, which cools the hydraulic system. Subsequently, the cooling water is delivered to the drill bit and the punch head via a first and second water guide pipe, directly reducing the temperature of these components. After absorbing heat, the cooling water returns to the water tank through the water guide pipe. Simultaneously, the second outlet of the water tank introduces the cooling water into an air cooler, which further reduces the water temperature using airflow. The cooled water then returns to the water tank. This cooling device for the rock drill test bench achieves the following technical effects: The cooling device transmits cooling water to the drill bit and the punch head through the first and second water guide pipes, directly cooling these high-temperature components locally to ensure they maintain a suitable temperature during testing. Used cooling water is further cooled by the air cooler. The cooled water is then returned to the water tank, forming a closed-loop recycling system and reducing cooling water waste.

[0114] The cooling device for the rock drill test bench also includes: an oil separator 600, a first check valve 700, a second check valve 800, a first solenoid valve 900, and a pressure sensor 1000.

[0115] Specifically, the oil separator 600 is a device for separating and storing oil in the cooling water, ensuring the purity of the cooling water. The first check valve 700 and the second check valve 800 are both devices for preventing backflow of cooling water, ensuring unidirectional flow. The first solenoid valve 900 is a switching device for controlling the flow of cooling water, controlling its flow by energizing or de-energizing. The pressure sensor 1000 is a device for monitoring the cooling water pressure, ensuring the system operates within a safe pressure range.

[0116] One end of the oil separator 600 is connected to the first inlet 102 of the water tank 100. The other end of the oil separator 600 is connected to one end of the first one-way valve 700 and one end of the second one-way valve 800. The other end of the second one-way valve 800 is connected to the other end of the second water guide pipe. The other end of the first one-way valve 700 is connected to one end of the first solenoid valve 900. The other end of the first solenoid valve 900 is connected to one end of the pressure sensor 1000. The other end of the pressure sensor 1000 is connected to the other end of the first water guide pipe. The oil separator 600 is used to separate and store oil in the cooling water. The first one-way valve 700 and the second one-way valve 800 are both used to prevent backflow of cooling water. The first solenoid valve 900 is used to control the flow and disconnection of cooling water. The pressure sensor 1000 is used to monitor the pressure of the cooling water.

[0117] Specifically, by integrating an oil separator 600, a check valve, a solenoid valve, and a pressure sensor 1000 into the cooling water circulation path, effective management and control of the cooling water are achieved. The oil separator 600 separates and stores oil in the cooling water, ensuring the system's clean and efficient operation. The first check valve 700 and the second check valve 800 prevent backflow of cooling water, maintaining the unidirectional and stable flow. The first solenoid valve 900 controls the flow of cooling water as needed, achieving precise control of the cooling process. The pressure sensor 1000 monitors the cooling water pressure, ensuring the system operates within a safe pressure range, thereby improving the cooling efficiency and safety of the rock drill test bench.

[0149] Specifically, the level switch 2800 is a sensor device installed on the water tank 100 to monitor the level of cooling water in the tank. When the level reaches a preset first level, the level switch can trigger the control system to take corresponding measures. The drain valve 2900, also installed on the water tank, is used to automatically or manually open to drain excess cooling water when the level is higher than the preset first level, thereby preventing the tank from overfilling and ensuring the normal operation and safety of the system.

[0150] The level switch 2800 and the drain valve 2900 are both installed on the water tank 100. The level switch 2800 is used to monitor the level of the water tank 100.

[0151] Specifically, both the level switch 2800 and the drain valve 2900 can be installed at appropriate locations in the water tank 100 by welding or riveting to monitor and control the water level in the tank. The level switch 2800 detects the level of cooling water in the tank using technologies such as a float, conductive probe, or ultrasonic waves, and transmits the signal to the control system. When the level exceeds a preset first level, the system can trigger the drain valve 2900 to open, automatically draining excess cooling water to prevent the tank from overflowing or affecting the normal operation of the cooling system. This mechanism ensures that the cooling device operates safely and efficiently.

[0152] When the liquid level is higher than the preset first liquid level, the drain valve 2900 is used to drain the cooling water in the water tank 100.

[0153] Specifically, when the level switch 2800 detects that the cooling water level in the water tank 100 is higher than a preset first level, the level switch sends a signal to the control system, triggering the opening of the drain valve 2900. The drain valve 2900 is typically an electrically or pneumatically controlled valve that automatically opens upon receiving a signal, allowing excess cooling water to drain from the water tank. This process aims to prevent the water tank from overfilling, avoiding equipment damage or reduced cooling efficiency due to overflow, and ensuring the normal and safe operation of the cooling system.

[0154] The technical advantages of this embodiment are as follows: the introduction of a level switch and a drain valve enhances the automated management and safety of the cooling device. The level switch monitors the liquid level in the tank in real time. When the liquid level exceeds a preset first level, the drain valve automatically discharges excess cooling water to prevent the tank from overflowing. This effectively prevents system failures or damage that may be caused by excessively high liquid levels, thus improving the operational stability and safety of the device.

[0155] The cooling device for the rock drill test bench also includes: a third solenoid valve 3000.

[0156] Specifically, the third solenoid valve 3000 is an electrically controlled valve connected between the external water inlet and the first water inlet 102 of the water tank 100.

When the level switch 2800 detects that the cooling water level in the water tank is lower than the preset second level, the third solenoid valve 3000 receives a control signal and automatically opens, allowing external water to enter the water tank to replenish the cooling water. This mechanism ensures that the cooling system is always maintained within an appropriate level range to guarantee its normal operation and cooling effect.

[0157] One end of the third solenoid valve 3000 is connected to an external water inlet, and the other end of the third solenoid valve 3000 is connected to the first water inlet 102 of the water tank 100; wherein, the third solenoid valve 3000 is used to control the flow and disconnection of cooling water.

[0158] Specifically, the third solenoid valve 3000 is connected to an external water inlet at one end through a piping system, and to the first water inlet 102 of the water tank 100 at the other end. Its function is to control the opening and closing of the valve via an electrical signal, thereby regulating the water supply process from the external water source to the water tank. When the level switch 2800 detects that the cooling water level in the tank is lower than a preset second level, the control system sends a signal to open the third solenoid valve 3000, allowing water supply; when the level reaches an appropriate level, the solenoid valve closes to stop water supply. This achieves automatic regulation of the cooling water level, ensuring the continuous and effective operation of the cooling system.

[0159] When the liquid level is lower than the preset second liquid level, the external water inlet is used to replenish cooling water to the water tank 100 through the third solenoid valve 3000.

[0160] Specifically, when the level switch 2800 detects that the cooling water level in the water tank 100 is lower than the preset second level, the level switch sends a signal to the control system, indicating that cooling water needs to be added. Upon receiving the signal, the control system activates the third solenoid valve 3000, opening it to allow water from the external water inlet to flow into the water tank 100. This process ensures that the cooling water level in the tank is always maintained within an appropriate range to maintain the normal operation and effectiveness of the cooling system, preventing a decrease in cooling efficiency or overheating of the equipment due to excessively low water levels.

[0161] The technical effect of this embodiment is that the third solenoid valve is connected to the external water inlet and the water tank. When the liquid level is lower than the preset second liquid level, it will automatically open to replenish the cooling water. This design reduces the need for manual intervention and ensures the stable operation of the cooling system.

[0162] The cooling system of the rock drill test bench also includes an air filter 3100 and a temperature sensor 3200.

[0163] Specifically, the air filter 3100 is used to balance the air pressure inside and outside the water tank.

The temperature sensor 3200 is used to monitor the temperature of the cooling water in the water tank in real time. By providing accurate temperature data, the temperature sensor 3200 helps the control system regulate the cooling process to ensure the system operates within a suitable temperature range, thereby improving cooling efficiency and equipment safety.

[0164] The air filter 3100 and the temperature sensor 3200 are both located on the water tank 100. The air filter 3100 is used to balance the air pressure inside and outside the water tank 100, and the temperature sensor 3200 is used to monitor the temperature of the cooling water in the water tank 100.

[0165] Specifically, the air filter 3100 and temperature sensor 3200 are both installed in appropriate locations within the water tank 100 to perform their respective functions. The air filter 3100 is connected to the water tank via a vent and is equipped with a filter medium to block dust and impurities from entering, while allowing free airflow to balance the air pressure inside and outside the water tank, preventing deformation or damage to the water tank due to pressure differences. The temperature sensor 3200 is in direct contact with or immersed in the cooling water in the water tank, measuring the water temperature in real time and transmitting the data to the control system. By monitoring the cooling water temperature, the system can make necessary adjustments to ensure efficient cooling and safe operation of the equipment.
