Description

Technical Field

[0001] This utility model relates to the technical field of tunnel cooling equipment, and in particular, to an internal circulation softening cooling system. Furthermore, this utility model also relates to a complete set of tunneling and anchoring equipment including the aforementioned internal circulation softening cooling system. Background Technology

[0002] The complete set of tunneling and anchoring equipment mainly includes an integrated tunneling and anchoring machine, a hydraulic anchor bolt transfer unit for coal mines, and a belt transfer machine for coal mines. The integrated tunneling and anchoring machine is primarily used for coal breaking and loading, and can also simultaneously perform partial roof and sidewall anchor bolt and cable support operations. The hydraulic anchor bolt drilling rig for coal mines is mainly used for anchor bolt and cable support operations on the remaining roof and sidewalls. The belt transfer machine for coal mines transfers coal to a belt conveyor, completing the continuous transportation process. During construction, the complete set of tunneling and anchoring equipment enables simultaneous operations of tunnel excavation, support, loading, and transportation, reducing the number of workers on the working face, lowering the labor intensity of workers, and improving work efficiency.

[0003] Currently, the cooling water for the motors in integrated tunneling and anchoring machines, the cooling water for the motors in hydraulic anchor bolt transfer units used in coal mines, the hydraulic system return oil cooling water, the drilling and slag removal water for anchor bolt machines, and the dust suppression spray water all utilize the roadway water intake. However, this water system has the following shortcomings:

[0004] 1) Due to the significant differences in water quality and pressure in different areas of the tunnels, the water entering the tunnels contains silt and rust, which causes scale to form in the cooling water under the influence of temperature. During use, scale can easily cause blockages in the cooling pipes, motors, and internal channels of the cooler, resulting in insufficient cooling water flow, excessively high motor and cooler temperatures that trigger overheat protection, frequent shutdowns, reduced construction efficiency of the tunneling and anchoring equipment, and even affecting the service life of the motor. Furthermore, the high local pressure after the motor is blocked poses a risk of damaging the motor.

[0005] 2) The cooling return water is directly used for drilling, slag flushing, and dust suppression spraying. However, it cannot achieve the synchronous effect of drilling and anchoring when the complete set of drilling and anchoring equipment is initially used. As a result, most of the cooling return water in the cutting and support processes is directly discharged into the roadway return water pipe, causing a large waste of water resources, low return water utilization rate, and large roadway drainage volume, which causes water accumulation in some roadways and affects construction efficiency. Utility Model Content

[0006] This utility model provides an internal circulation softening cooling system and a complete set of tunneling and anchoring equipment to solve the technical problems of existing water system such as easy blockage of cooling pipes, insufficient motor cooling leading to high temperature shutdown, low return water utilization rate, and low tunneling construction efficiency.

[0007] According to one aspect of the present invention, an internal circulation softening and cooling system is provided, comprising a water supply treatment component for purifying and softening roadway influent to supply soft water, a water storage component connected to the water supply treatment component for storing soft water, a drive pump unit connected to the water storage component for pumping soft water, a hydraulic oil cooler connected to the drive pump unit for connecting a hydraulic system and a working motor to cool the hydraulic system return oil and supply cooling water to the working motor, and a water cooler connected to the water storage component and the water supply treatment component respectively for connecting the working motor to cool the return water of the working motor and supplying cooling water to the bolting machine and the roadheader.

[0008] As a further improvement to the above technical solution:

[0009] Furthermore, the water supply treatment assembly includes a static pressure water purifier connected to a water cooler for filtering impurities in the roadway inlet water and supplying cooling water to the water cooler, a water supply ball valve connected to the static pressure water purifier for controlling the water flow, and a static pressure water softener connected to the water supply ball valve and the water storage assembly respectively for softening the filtered roadway inlet water to form soft water supplied to the water storage assembly.

[0010] Furthermore, the water storage assembly includes a water storage tank that is connected to the water supply and treatment assembly, the drive pump assembly, and the water cooler, respectively; a temperature sensor installed on the water storage tank for monitoring water temperature and transmitting control signals; a level sensor installed on the water storage tank for monitoring water level and transmitting control signals to the water supply and treatment assembly for whether to supply water; and a drain ball valve connected to the water storage tank for controlling whether to drain water from the water storage tank based on the control signals transmitted by the temperature sensor.

[0011] Furthermore, the drive pump set includes a first electric water pump and a second electric water pump connected in parallel with the water storage component, a first pump ball valve for controlling the outlet flow rate of the first electric water pump on the pipeline between the first electric water pump and the hydraulic oil cooler, and a second pump ball valve for controlling the outlet flow rate of the second electric water pump on the pipeline between the second electric water pump and the hydraulic oil cooler.

[0012] Furthermore, the drive pump assembly also includes a safety valve for overflow pressure relief, which is connected to the outlet end of the first electric water pump, the outlet end of the second electric water pump, and the return end of the water storage assembly, respectively; and / or the drive pump assembly also includes a pressure sensor for detecting water pressure, which is connected to the outlet end of the first electric water pump and the outlet end of the second electric water pump, respectively.

[0013] Furthermore, the internal circulation softening cooling system also includes a filter for filtering impurities in the water, which is installed in the pipeline between the drive pump unit and the hydraulic oil cooler.

[0014] Furthermore, the internal circulation softening cooling system also includes a pressure gauge for displaying water pressure on the pipeline laid between the drive pump set and the hydraulic oil cooler.

[0015] Furthermore, the internal circulation softening cooling system also includes a pressure reducing valve for controlling water pressure, which is installed on the pipeline between the drive pump set and the hydraulic oil cooler.

[0016] Furthermore, the internal circulation softening cooling system also includes a safety valve 2, which is installed on the pipeline between the pressure reducing valve and the hydraulic oil cooler, to connect the return end of the water storage component for overflow pressure relief.

[0017] According to another aspect of the present invention, a set of excavation and anchoring equipment is also provided, which includes the aforementioned internal circulation softening and cooling system.

[0018] This utility model has the following beneficial effects:

[0019] This utility model's internal circulation softening and cooling system, after the water supply and treatment components connect to the roadway inlet, purifies and softens the roadway inlet water before supplying soft water to the storage component until the storage component stores a preset capacity of soft water. A drive pump unit pumps the soft water from the storage component to a hydraulic oil cooler. The hydraulic oil cooler connects to the hydraulic system and the working motor, cooling the hydraulic system's return oil and supplying cooling water to the working motor. The return water from the working motor flows into the water cooler and then into the storage component, achieving internal circulation of the cooling soft water. Simultaneously, the water supply and treatment components supply cooling water to the water cooler to cool the return water from the working motor, ensuring the cooling soft water temperature remains within a set range so that the soft water in the storage component can operate continuously in internal circulation mode. The cooler also supplies cooling water from the return water of the working motor to the dust suppression spray of the roadheader and the drilling and slag removal of the bolting machine, thus realizing the secondary use of cooling water. Compared with existing technologies, this solution purifies and softens the roadway influent through a water treatment component to remove impurities. The use of soft water for circulating cooling reduces the risk of scaling and blockage in cooling pipes, working motors, and internal channels of the cooler. The working motor is adequately cooled, avoiding high-temperature shutdowns, reducing the failure rate, and improving construction efficiency. The dust suppression spray of the roadheader and the drilling and slag removal of the bolting machine use only cooling water from the water cooler. This reduces total water consumption, increases recycling rates, and prevents water accumulation in the roadway, further improving construction efficiency. It is highly practical and suitable for widespread promotion and application.

[0020] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0026] like Figure 1 As shown, the internal circulation softening and cooling system of this embodiment includes a water supply treatment component 10 for purifying and softening the roadway inlet water to supply soft water, a water storage component connected to the water supply treatment component 10 for storing soft water, a drive pump group connected to the water storage component for pumping soft water, a hydraulic oil cooler 40 connected to the drive pump group for connecting the hydraulic system and the working motor to cool the hydraulic system return oil and supply cooling water to the working motor, and a water cooler 50 connected to the water storage component and the water supply treatment component 10 for connecting the working motor to cool the return water of the working motor and supplying cooling water to the bolting machine and the anchor bolting machine.

[0027] like Figure 1As shown, specifically, the internal circulation softening and cooling system of this utility model, after the water supply treatment component 10 is connected to the roadway inlet water, purifies and softens the roadway inlet water through the water supply treatment component 10, and then supplies soft water to the water storage component until the water storage component stores a preset capacity of soft water; by driving the pump set to work, the soft water in the water storage component is pumped to the hydraulic oil cooler 40. The hydraulic oil cooler 40 is connected to the hydraulic system and the working motor to cool the hydraulic system return oil and supply cooling water to the working motor; the return water from the working motor flows into the water cooler 50 and then into the water storage component to realize the internal circulation of cooling soft water. At the same time, the water supply treatment component 10 supplies cooling water to the water cooler 50 to cool the return water from the working motor, so as to ensure that the water temperature of the cooling soft water is maintained within the set range, so that the soft water in the water storage component can be in internal circulation state. During prolonged operation, the water cooler 50 also supplies cooling water from the return water of the working motor to the dust suppression spray of the roadheader and the drilling and slag removal of the bolting machine, thus achieving secondary utilization of cooling water. Compared with existing technologies, this solution purifies and softens the roadway inlet water through the water treatment component 10 to remove impurities. The use of soft water for circulating cooling reduces the risk of scaling and blockage in the cooling pipes, working motor, and internal channels of the cooler. The working motor is adequately cooled, avoiding high-temperature shutdowns, reducing the failure rate, and improving construction efficiency. The dust suppression spray of the roadheader and the drilling and slag removal of the bolting machine are sourced solely from the cooling water of the water cooler 50. This reduces total water consumption, increases recycling rates, and prevents water accumulation in the roadway, further improving construction efficiency. It is highly practical and suitable for widespread promotion and application.

[0028] It should be understood that the hydraulic oil cooler 40 adopts heat exchange cooling, that is, the hydraulic oil in the hydraulic system is cooled by soft water pumped by the drive pump set.

[0029] It should be understood that the water cooler 50 adopts heat exchange cooling, that is, the cooling water supplied by the water treatment component 10 cools the return water of the working motor.

[0030] It should be understood that the preset capacity can be adaptively set according to the operational needs.

[0031] It should be understood that the working motor refers to the motor in the tunneling and anchoring machine and the motor in the hydraulic anchor bolt transfer unit for coal mines.

[0032] like Figure 1 As shown, in this embodiment, the water supply treatment component 10 includes a static pressure water purification component 11 connected to the water cooler 50 for filtering impurities in the roadway inlet water and supplying cooling water to the water cooler 50, a water supply ball valve 12 connected to the static pressure water purification component 11 for controlling the water flow, and a static pressure water softening component 13 connected to the water supply ball valve 12 and the water storage component for softening the filtered roadway inlet water to form soft water supplied to the water storage component.

[0033] Specifically, the roadway inlet water is filtered by the static pressure water purification component 11 to remove impurities. The static pressure water softening component 13 softens the filtered roadway inlet water, removing Ca and Mg ions, to form soft water that is supplied to the water storage component. During the water supply process, the flow rate from the static pressure water purification component 11 to the static pressure water softening component 13 is controlled by the water supply ball valve 12 to control the amount of soft water stored in the water storage component. This prevents the soft water from overflowing due to excessive soft water in the water storage component, thus avoiding water waste or excessive pressure in the internal circulation pipeline that could damage the components.

[0034] like Figure 1 As shown, in this embodiment, the water storage component includes a water storage tank 21 that is connected to the water supply treatment component 10, the drive pump group and the water cooler 50 respectively; a temperature sensor 22 installed on the water storage tank 21 for monitoring water temperature and transmitting control signals; a level sensor 23 installed on the water storage tank 21 for monitoring water level and transmitting control signals to the water supply treatment component 10 for whether to supply water; and a drain ball valve 24 connected to the water storage tank 21 for controlling whether to drain water from the water storage tank 21 according to the control signals transmitted by the temperature sensor 22.

[0035] Specifically, after storing a preset capacity of soft water supplied by the water treatment component 10, the water storage tank 21 is pumped by the drive component to receive the returned cooling soft water from the water cooler 50, thus achieving internal circulation of the cooling soft water. The temperature sensor 22 detects the temperature of the soft water in the water storage tank 21 and transmits a corresponding control signal to the drain ball valve 24. The drain ball valve 24 controls whether to drain water from the water storage tank 21 according to the control signal transmitted by the temperature sensor 22. That is, when the temperature of the soft water in the water storage tank 21 exceeds the set temperature, the drain ball valve 24 opens to release water, and the soft water in the water storage tank 21... When the temperature does not exceed the set temperature, the drain ball valve 24 is closed to ensure that the temperature of the soft water recovered by the cooling motor and hydraulic system is maintained below the set temperature, thus ensuring the cooling effect and improving the cooling efficiency. After draining the water, water can be replenished through the water supply treatment component 10. The level sensor 23 detects the water level in the water storage tank 21 and transmits a control signal to the water supply treatment component 10 to control whether to supply water. When the water level in the water storage tank 21 exceeds the preset capacity, the water supply ball valve 12 is closed to stop the water supply. When the water level in the water storage tank 21 does not exceed the preset capacity, the water supply ball valve 12 is opened to supply water.

[0036] Optionally, the internal circulation softening cooling system also includes a controller electrically connected to the temperature sensor 22, the liquid level sensor 23, the water supply ball valve 12, and the water discharge ball valve 24, respectively. The controller transmits an electrical control signal to the water discharge ball valve 24 to indicate whether the water is open or closed based on the temperature of the soft water in the water storage tank 21 detected by the temperature sensor 22; and transmits an electrical control signal to the water supply ball valve 12 to indicate whether the water is open or closed based on the water level in the water storage tank 21 detected by the liquid level sensor 23.

[0037] Optionally, the controller is a PLC controller.

[0038] Optionally, the water supply ball valve 12 is an electric ball valve, which can be switched on and off under the electrical control signal of the controller.

[0039] Optionally, the drain ball valve 24 is an electric ball valve, which can be switched on and off under the electrical control signal of the controller.

[0040] like Figure 1 As shown, in this embodiment, the drive pump set includes a first electric water pump 31 and a second electric water pump 32 connected in parallel with the water storage component, a first pump ball valve 33 for controlling the outlet flow rate of the first electric water pump 31 on the pipeline between the first electric water pump 31 and the hydraulic oil cooler 40, and a second pump ball valve 34 for controlling the outlet flow rate of the second electric water pump 32 on the pipeline between the second electric water pump 32 and the hydraulic oil cooler 40. Specifically, when the first pump ball valve 33 is opened, the first electric pump 31 starts to pump cooling soft water; when the second pump ball valve 34 is opened, the second electric pump 32 starts to pump cooling soft water. That is, the first electric pump 31 and the second electric pump 32 alternate operation by switching the working state of the first pump ball valve 33 and the second pump ball valve 34. The first electric pump 31 and the second electric pump 32 are arranged in parallel, that is, a one-in-one standby mode is adopted. That is, when the first pump ball valve 33 is connected, the second pump ball valve 34 is closed so that the first electric pump 31 pumps cooling soft water. When the first electric pump 31 fails, the first pump ball valve 33 is closed and the second pump ball valve 34 is connected so that the second electric pump 32 pumps cooling soft water. This ensures that the supply of cooling soft water is guaranteed as much as possible in special circumstances, so as to reduce the downtime rate of the tunneling and anchoring equipment and ensure construction efficiency.

[0041] Optionally, the first electric water pump 31 is a combination of a prime mover and a hydraulic pump, wherein the prime mover is an electric motor or an engine.

[0042] Optionally, the second electric water pump 32 is a combination of a prime mover and a hydraulic pump, wherein the prime mover is an electric motor or an engine.

[0043] Optionally, the controller is electrically connected to the first electric water pump 31, the second electric water pump 32, the first water ball valve 33, and the second water ball valve 34 respectively, so as to control the first electric water pump 31, the second electric water pump 32, the first water ball valve 33, and the second water ball valve 34 to work together.

[0044] Optionally, the first pump water ball valve 33 is an electric ball valve, which can be switched on and off under the electrical control signal of the controller.

[0045] Optionally, the second pump water ball valve 34 is an electric ball valve, which can be switched on and off under the electrical control signal of the controller.

[0046] like Figure 1 As shown, in this embodiment, the drive pump set also includes a safety valve 35 for overflow pressure relief, which is connected to the outlet end of the first electric water pump 31, the outlet end of the second electric water pump 32, and the return end of the water storage component. Specifically, when the water pressure at the outlet end of the first electric water pump 31 exceeds a set value or the water pressure at the outlet end of the second electric water pump 32 exceeds a set value, the safety valve 35 overflows to relieve pressure, so that soft water flows back to the water storage component, protecting the first electric water pump 31 and the second electric water pump 32 to operate normally and preventing high-pressure damage to the first electric water pump 31 and the second electric water pump 32.

[0047] Optionally, safety valve 35 is an overflow valve.

[0048] like Figure 1 As shown, in this embodiment, the drive pump set also includes a pressure sensor 36 for detecting water pressure, which is connected to the outlet end of the first electric water pump 31 and the outlet end of the second electric water pump 32, respectively. Specifically, the pressure sensor 36 detects the water pressure at the outlet end of the first electric water pump 31 and the outlet end of the second electric water pump 32. When the pressure reaches a set value, a control signal is transmitted to issue an alarm signal or control the first electric water pump 31 and / or the second electric water pump 32 to stop, which can effectively prevent local high-pressure damage to the first electric water pump 31 and the second electric water pump 32.

[0049] Optionally, pressure sensor 36 is connected to the controller.

[0050] like Figure 1 As shown, in this embodiment, the internal circulation softening and cooling system also includes a filter 60 installed on the pipeline between the drive pump set and the hydraulic oil cooler 40 to filter impurities in the water. Specifically, the filter 60 filters impurities in the soft water pumped by the drive pump set, ensuring that the water meets the usage requirements of the hydraulic oil cooler 40, the working motor, and the water cooler 50.

[0051] like Figure 1 As shown, in this embodiment, the internal circulation softening cooling system also includes a pressure gauge 70 for displaying water pressure, which is installed on the pipeline between the drive pump set and the hydraulic oil cooler 40. Specifically, the pressure gauge 70 displays the water pressure so that the relevant ball valves can be manually controlled after observation.

[0052] like Figure 1 As shown, in this embodiment, the internal circulation softening cooling system also includes a pressure reducing valve 80 for controlling water pressure, which is installed on the pipeline between the drive pump set and the hydraulic oil cooler 40. Specifically, the pressure reducing valve 80 controls the maximum pressure of the soft water pumped by the drive pump set to prevent excessive pressure from damaging the hydraulic oil cooler 40, the working motor, and the water cooler 50, and to avoid cross-contamination between the hydraulic oil and the cooling soft water.

[0053] like Figure 1 As shown, in this embodiment, the internal circulation softening cooling system also includes a second safety valve 90 located on the pipeline between the pressure reducing valve 80 and the hydraulic oil cooler 40, for connecting the return end of the water storage component to overflow and relieve pressure. Specifically, when the water pressure inside the pipeline between the pressure reducing valve 80 and the hydraulic oil cooler 40 is too high, the second safety valve 90 opens to allow the cooling soft water to flow back to the water storage component, achieving overflow and pressure relief, preventing damage to the hydraulic oil cooler 40, the working motor, and the water cooler 50 due to excessive pressure, and avoiding cross-contamination between the hydraulic oil and the cooling soft water.

[0054] Optionally, safety valve 290 is an overflow valve.

[0055] The tunneling and anchoring equipment of this embodiment includes the aforementioned internal circulation softening and cooling system. Specifically, since the technical effects of the "tunneling and anchoring equipment" provided in this embodiment are the same as those of the "internal circulation softening and cooling system" provided in the above embodiment, they will not be described again here.

[0056] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
