Abstract
Description
Technical Field
[0001] The present invention relates to the field of tunnel boring, and particularly to a core acquisition device based on a rope fishing tool. Background Art
[0002] During the process of tunnel boring, if sudden large-area water inrush or broken zone strata occurs, it will bring inestimable losses to the entire tunnel boring project. Therefore, before tunnel boring, generally a core drilling device is used to take out a certain number of cores from the tunnel. By analyzing and studying the cores, a certain range of exploration of the strata around the tunnel is carried out to understand the properties and variation laws of the rock strata around the tunnel, and then to guide the tunnel boring operation, which can improve the safety and boring efficiency during the tunnel boring process.
[0003] In the prior art, a core acquisition device based on a rope fishing tool is provided for acquiring cores. The rope fishing tool is respectively connected to a centrifugal pump and a winch. The centrifugal pump is connected to a water joint. The rope fishing tool is sent to the front end of the drill bit of the core drilling rod by using water pressure. The inner pipe drilling tool is extracted by the rope fishing tool; then the rope fishing tool is pulled back by the winch, so as to obtain the cores obtained by the inner pipe drilling tool. Before taking out the rope fishing tool, it is necessary to disconnect the centrifugal pump from the water joint and drain the water in the core drilling rod in order to take out the rope fishing tool. The process of frequently disassembling and assembling the water joint connected to the centrifugal pump is time-consuming, laborious and labor-intensive. Especially when drilling horizontal holes or upward holes, due to the large water return pressure, during the process of disassembling and assembling the pipeline connected to the water joint, the water column will splash everywhere, seriously affecting the environment and safety of the drilling site. In addition, there are many rock debris at the drilling site, and the debris entrained in the pipe threads makes it difficult to unscrew the threads. Frequent disassembly and assembly of the pipeline will not only reduce the service life of the threads, but also reduce the sealing performance of the pipeline.
[0004] Therefore, how to improve the convenience of obtaining cores by the rope fishing tool, reduce the consumption of manpower and time, and ensure the sealing performance of the pipeline is a technical problem that needs to be solved by those skilled in the art at present.

[0031] Figure 2 It is a schematic structural diagram of another apparatus for obtaining a core based on a wireline retrievable tool provided by an embodiment of the present invention. Detailed Embodiments
[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0033] The core of the embodiment of the present invention is to provide a core acquisition device based on a rope fishing tool, which can improve the convenience of obtaining cores through the rope fishing tool, reduce the consumption of manpower and time, and ensure the sealing of the pipeline.
[0034] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0035] Figure 1 It is a schematic structural diagram of a core acquisition device based on a rope fishing tool provided by an embodiment of the present invention. As Figure 1 shown, a core acquisition device based on a rope fishing tool includes:
[0036] A centrifugal pump 13 connected to the core drill pipe 11 through a first pipeline, which is used to use water pressure to send the rope fishing tool 12 placed in the core drill pipe 11 to the front end of the drill bit of the core drill pipe 11, and a winch 14 connected to the rope fishing tool 12, which is used to fish out the rope fishing tool 12 from the front end of the drill bit of the core drill pipe 11 by retracting and releasing the rope. It also includes:
[0037] A regulating valve 15 connected to the core drill pipe 11 through a second pipeline, which is used to control the on-off of the second pipeline according to the operation requirements of the rope fishing tool 12;
[0038] A check valve 16 connected to the centrifugal pump 13, which is used to close the first pipeline when draining water through the second pipeline.
[0039] Specifically, the centrifugal pump 13 refers to a pump that transports liquids by the centrifugal force generated when the impeller rotates. It mainly consists of an impeller, a pump body, a pump shaft, bearings, a sealing ring, and a stuffing box, etc. It can be understood that in actual operation, the centrifugal pump 13 must be connected to a water source to use water pressure to push the rope fishing tool 12. The water supply equipment used as the water source in this embodiment is not limited. By connecting the core drill pipe 11 to the centrifugal pump 13 through the first pipeline, and then placing the rope fishing tool 12 into the core drill pipe 11, the centrifugal pump 13 uses water pressure to send the rope fishing tool 12 to the front end of the drill bit of the core drill pipe 11. It should be noted that in actual operation, the speed of the centrifugal pump 13 can be adjusted to control the speed of sending the rope fishing tool 12. More specifically, when the rope fishing tool 12 is at the entrance of the core drill pipe 11 or in the middle of the core drill pipe 11, the speed of the centrifugal pump 13 can be increased to accelerate the sending of the rope fishing tool 12. When the rope fishing tool 12 is close to the front end of the drill bit of the core drill pipe 11, the speed of the centrifugal pump 13 needs to be reduced to reduce the speed of sending the rope fishing tool 12.
[0040] Specifically, the hoist 14 refers to a light and small lifting device that winds a wire rope or chain around a drum to lift or tow heavy objects, also known as a winch. In this embodiment, by connecting the rope salvage device 12 to the hoist 14, the rope salvage device 12 can be retrieved from the front end of the drill bit of the core drill pipe 11 by winding and unwinding the rope through the hoist 14. When retrieving the core, the core is obtained through the inner pipe drill tool, and then the inner pipe drill tool is extracted through the rope salvage device 12, thereby obtaining the core.
[0041] It should be noted that the first pipeline in this embodiment refers to the pipeline for sending water into the core drill pipe 11, and the second pipeline refers to the pipeline for discharging water from the core drill pipe 11, and "first" and "second" are not used as specific limitations.
[0042] It can be understood that since the rope salvage device 12 is sent to the front end of the drill bit of the core drill pipe 11 by using water pressure, a large amount of water will be stored in the core drill pipe 11. Therefore, before retrieving the rope salvage device 12, the water in the core drill pipe 11 needs to be discharged. In this embodiment, the regulating valve 15 is connected to the core drill pipe 11 through the second pipeline, and then the on-off of the second pipeline is controlled according to the operation requirements of the rope salvage device 12. More specifically, when the rope salvage device 12 needs to be sent in, the second pipeline is closed by controlling the regulating valve 15, and at this time, the centrifugal pump 13 is used to send water into the core drill pipe 11; when the rope salvage device 12 needs to be retrieved, the second pipeline is opened by controlling the regulating valve 15 to discharge the water in the core drill pipe 11.
[0043] In actual operation, when discharging the water in the core drill pipe 11, the first pipeline needs to be closed at the same time. Therefore, in this embodiment, a check valve 16 is further provided on the second pipeline connected to the centrifugal pump 13 to prevent water from flowing back and protect the components.
[0044] A core acquisition device based on a rope salvage device provided by an embodiment of the present invention further includes a regulating valve connected to the core drill pipe through a second pipeline. The on-off of the second pipeline can be controlled through the regulating valve according to the operation requirements of the rope salvage device. That is to say, when the rope salvage device needs to be taken out, the regulating valve can be opened to discharge the water in the core drill pipe by using the second pipeline. Therefore, this device can avoid frequently disassembling and assembling the water joint connected to the centrifugal pump, thereby reducing the consumption of manpower and time, ensuring the sealing of the pipeline, and improving the convenience of obtaining the core through the rope salvage device.
[0045] Figure 2 This is a schematic structural diagram of another core acquisition device based on a rope salvage device provided by an embodiment of the present invention. As Figure 2 shown, on the basis of the above embodiment, this embodiment further explains and optimizes the technical solution. Specifically, this embodiment further includes:
[0046] A pressure sensor 17 connected to the centrifugal pump 13 for detecting the water pressure value in the first pipeline;
[0047] A calculator 18 connected to the pressure sensor 17 for receiving the water pressure value and calculating the feeding force of the centrifugal pump 13 based on the water pressure value;
[0048] A controller 19 connected to the calculator 18 for adjusting the rotational speed of the centrifugal pump 13 or the rope pulling force of the winch 14 according to the feeding force and the rope pulling force of the winch 14.
[0049] First of all, it should be noted that in actual operation, the pressure sensor 17, the calculator 18 and the controller 19 can also be integrated, and this embodiment does not limit this.
[0050] Specifically, the pressure sensor 17 is used to detect the water pressure value in the first pipeline, and this embodiment does not limit the specific type of the pressure sensor 17.
[0051] Specifically, the calculator 18 receives the water pressure value obtained by the pressure sensor 17, and then calculates the feeding force of the centrifugal pump 13 to send the rope fishing tool 12 to the front end of the drill bit of the core drill pipe 11 based on the water pressure value. It should be noted that specifically, it can be calculated according to factors such as the water pressure value, the inner diameter of the feeding pipeline, and the water quality, and this embodiment does not limit the specific calculation method.
[0052] Specifically, the controller 19 adjusts the rotational speed of the centrifugal pump 13 or adjusts the rope pulling force of the winch 14 according to the feeding force calculated by the calculator 18 and the rope pulling force of the winch 14, so as to achieve the balance between the feeding force and the rope pulling force, so as to realize the acceleration and deceleration adjustment of the feeding speed of the rope fishing tool 12 during the process of sending the rope fishing tool 12 to the front end of the drill bit of the core drill pipe 11, thereby reducing the collision force between the rope fishing tool 12 and the front end of the drill bit of the core drill pipe 11 and protecting the rope fishing tool 12 and the core drill pipe 11.
[0053] On the basis of the above embodiment, this embodiment further explains and optimizes the technical solution. Specifically, in this embodiment, the water supply device for supplying water to the centrifugal pump 13 and the water storage device for storing the return water are specifically the water tank 20.
[0054] Specifically, the water tank 20 refers to a device capable of storing water. Therefore, in this embodiment, the water tank 20 can be used as both a water supply device and a water storage device. In actual operation, the centrifugal pump 13 and the regulating valve 15 are respectively connected to the water tank 20 through corresponding pipelines, and the water in the water tank 20 is used to supply water to the centrifugal pump 13. At the same time, when draining water from the core drill pipe, the discharged water is stored in the water tank, thereby realizing the recycling of water and avoiding waste of water resources.
[0055] Based on the above embodiments, the technical solution in this embodiment is further described and optimized. Specifically, this embodiment further includes:
[0056] A liquid level switch 21 disposed on the side wall of the tank body of the water tank 20, used to detect the water level in the water tank 20 and control the closing of the centrifugal pump 13 when the water level is lower than a preset water level threshold.
[0057] It can be understood that as the centrifugal pump 13 sends the water in the water tank 20 into the core drill pipe 11 through the first pipeline, the water level in the water tank 20 will gradually drop. In this embodiment, the liquid level switch 21 is disposed on the side wall of the tank body of the water tank 20, and the liquid level switch 21 is used to detect the water level in the water tank 20. The position where the liquid level switch 21 is set is the preset water level threshold. When the water level drops below the position where the liquid level switch 21 is set, it means that the current water level is lower than the preset water level threshold, that is, it means that the water volume in the water tank 20 is insufficient. Therefore, the centrifugal pump 13 is controlled to close by disconnecting the circuit of the liquid level switch 21, so as to avoid dry suction of the centrifugal pump 13 caused by too low water level in the water tank 20 and damage to the centrifugal pump 13.
[0058] As a preferred implementation manner, this embodiment further includes:
[0059] A prompting device connected to the liquid level switch 21, used to send a corresponding prompting message when the water level is lower than a preset water level threshold.
[0060] Specifically, when it is detected by the liquid level switch 21 that the water volume in the water tank 20 is insufficient, a corresponding prompting message is further sent through the prompting device connected to the liquid level switch 21 to notify the user that the water level in the current water tank 20 is relatively low and water needs to be replenished in time.
[0061] It should be noted that the specific type of the prompting device in this embodiment is not limited. As a preferred implementation manner, the prompting device can be a buzzer and / or an indicator light. It can be understood that the buzzer and the indicator light, as common prompting devices, can not only simply and intuitively achieve the prompting effect, but also are simple to use and inexpensive. Therefore, the buzzer and / or the indicator light are preferably used as the prompting device in this embodiment.
[0062] It can be seen that in this embodiment, by further using the prompting device to prompt the current water level situation, the damage to the centrifugal pump is further avoided.
[0063] Based on the above embodiments, the technical solution in this embodiment is further described and optimized. Specifically, this embodiment further includes:
[0064] A filter 22 disposed in the second pipeline between the regulating valve 15 and the water tank 20, used to filter the return water.
[0065] It can be understood that in this embodiment, since the water in the core drill pipe 11 is discharged through the second pipeline and recycled into the water tank 20, this embodiment further includes a filter 22 disposed in the second pipeline between the regulating valve 15 and the water tank 20. The filter 22 is used to filter out impurities in the return water in the second pipeline, ensuring the cleanliness of the return water returned to the water tank 20, so as to facilitate the recycling of the water in the water tank 20.
[0066] It can be seen that by further providing the filter 22 in the second pipeline between the regulating valve 15 and the water tank 20 in this embodiment, the cleanliness of the water in the water tank 20 can be improved, the recycling of water can be achieved, and water resources can be saved.
[0067] Based on the above embodiment, this embodiment further explains and optimizes the technical solution. Specifically, this embodiment further includes:
[0068] A flowmeter 23 disposed in the first pipeline for real-time measurement of the water flow value in the first pipeline;
[0069] A display 24 connected to the flowmeter 23 for receiving and displaying the water flow value.
[0070] Specifically, the flowmeter 23 refers to an instrument used to test the water flow condition in the first pipeline, specifically indicating the total fluid volume of the water in the first pipeline within a selected time interval. It can be understood that there are various types of flowmeters 23, and the specific type of the flowmeter 23 is not limited in this embodiment.
[0071] It can be understood that during the process of sending the rope fishing device 12, the water flow in the first pipeline may change due to external factors such as the environment or the working voltage of the centrifugal pump 13. Therefore, this embodiment further sets a flowmeter 23 in the first pipeline to real-time measure the water flow value in the first pipeline.
[0072] Specifically, after obtaining the water flow value by using the flowmeter 23, the obtained flow value will be further displayed through the display 24. It should be noted that the display 24 can specifically be a TFT (Thin Film Transistor) liquid crystal display or a UFB (Ultra Fine & Bright) liquid crystal display or an OLED (Organic Light-Emitting Diode) display, etc.
[0073] It should be noted that in actual operation, the display 24 can be set in the main control room. Therefore, according to the matching relationship between the running speed of the rope salvage device 12 and the water flow value, the water flow value can be controlled by adjusting the rotation speed of the centrifugal pump 13, so as to more accurately control the running speed of the rope salvage device.
[0074] It can be seen that in this embodiment, by further using the display screen to display the real-time monitored water flow value, it is more convenient for users to view and further improves the user experience.
[0075] On the basis of the above embodiments, this embodiment further explains and optimizes the technical solution. Specifically, this embodiment further includes:
[0076] A safety valve connected to the pressure sensor 17, used to set the rated water pressure in the first pipeline and open when the water pressure value is greater than the rated water pressure value to control the water pressure value in the first pipeline not to exceed the rated water pressure value.
[0077] Considering that in actual operation, there may be a situation where the water pressure value in the current first pipeline is too high, resulting in damage to the instrument. In this embodiment, a safety valve 25 is further provided. By setting the rated water pressure value in the first pipeline in the safety valve 25, if the detected water pressure value in the current first pipeline is less than the rated water pressure value, it means that the current first pipeline is in a normal state and the safety valve is closed; if the detected water pressure value in the current first pipeline is greater than the rated water pressure value, by opening the safety valve 25, some water in the first pipeline is discharged, so as to achieve the effect of reducing the water pressure in the first pipeline, that is, controlling the water pressure value in the first pipeline not to exceed the rated water pressure value.
[0078] It can be seen that in this embodiment, a safety valve is further provided in the first pipeline to ensure the water pressure safety of the entire device.
[0079] On the basis of the above embodiments, this embodiment further explains and optimizes the technical solution. Specifically, this embodiment further includes:
[0080] Pressure gauges 26 respectively arranged in the first pipeline and the second pipeline, used to display the water pressure values in the corresponding pipelines.
[0081] Specifically, in this embodiment, pressure gauges 26 are respectively arranged in the first pipeline and the second pipeline to respectively display the pressure values in the first pipeline and the second pipeline. It should be noted that since the pressure gauges 26 are suitable for detecting the pressure values in the first pipeline and the second pipeline, the pressure gauges 26 are generally arranged in the middle position of the pipeline to avoid deviation of the detection results caused by the influence of the water pressure values at the water inlet or the water outlet.
[0082] It can be understood that there are various types of pressure gauges 26. For example, according to the display type, there are digital and pointer pressure gauges. According to the accuracy type, there are also pressure gauges with various different accuracies. The specific type of the pressure gauge in this embodiment is not limited and is generally selected according to actual needs.
[0083] It can be seen that in this embodiment, the water pressure values in the first pipeline and the second pipeline are further detected by the pressure gauge, enabling the user to directly and clearly know the water pressure situation in the current pipeline, so as to adjust the centrifugal pump or the check valve and ensure the safety of the pipeline.
