[0028] In order to better understand the above technical solutions, the exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0029] A method and device for judging and locating the fault of a hydraulic support liquid supply system according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0030] Figure 1This is a flowchart illustrating a method for judging and locating faults in a hydraulic support fluid supply system, according to an embodiment of this application.

[0031] like Figure 1 As shown in the embodiments of this application, the method for judging and locating faults in the hydraulic support fluid supply system specifically includes the following steps:

[0032] S101. Collect the pressure and flow rate of the inter-stand fluid supply line to obtain the pressure and flow rate of the inter-stand fluid supply line.

[0033] In this embodiment of the application, when collecting data on the pressure and flow rate of the inter-rack fluid supply pipeline, the collection period for the pressure and flow rate of the inter-rack fluid supply pipeline can be obtained, and the pressure and flow rate of the inter-rack fluid supply pipeline can be collected according to the collection period.

[0034] It should be noted that after collecting the pressure and flow rate of the inter-frame liquid supply pipeline in the fully mechanized mining face, other data of the fully mechanized mining face can also be collected.

[0035] For example, the pressure of the supply pump station, the pressure of the high-pressure filter station, the pressure of the return filter station, the pressure of the return pipeline between the racks, the flow rate of the scraper conveyor trough supply end, the flow rate of the scraper conveyor trough return pipeline, and the flow rate of the return pipeline between the racks can be collected.

[0036] It should be noted that when collecting the pressure of the inter-support fluid supply line and the inter-support fluid return line, optionally, the pressure of the inter-support fluid supply line and the inter-support fluid return line of all hydraulic supports can be collected; optionally, the pressure of the inter-support fluid supply line and the inter-support fluid return line of the head and tail of the hydraulic support can be collected separately.

[0037] It should be noted that when collecting the flow rate of the inter-stand fluid supply pipeline, if the number of fluid supply sub-pipelines is greater than 1, the flow rate of each sub-pipeline is accumulated as the flow rate of the inter-stand fluid supply pipeline.

[0038] For example, when the number of liquid supply sub-pipes is x, the flow rate of the inter-rack liquid supply pipeline is Qg = Qg1 + Qg2 + ... + Qgx. Where Qg is the flow rate of the inter-rack liquid supply pipeline, Qg1 is the flow rate of liquid supply sub-pipe 1, Qg2 is the flow rate of liquid supply sub-pipe 2, and Qgx is the flow rate of liquid supply sub-pipe x.

[0039] S102. Obtain the pressure threshold and flow threshold of the inter-stand fluid supply pipeline.

[0040] It should be noted that this application does not impose any restrictions on the setting of pressure threshold and flow threshold for inter-stand fluid supply lines, which can be set according to actual conditions.

[0041] For example, an inter-stand liquid supply pipeline pressure threshold value P b and an inter-stand liquid supply pipeline flow threshold value Q gb can be set.

[0042] Further, due to the large number of liquid supply sub-pipelines, a liquid supply sub-pipeline flow threshold value can also be set.

[0043] S103, judging whether the hydraulic support liquid supply system fails according to the inter-stand liquid supply pipeline pressure, the inter-stand liquid supply pipeline flow, the inter-stand liquid supply pipeline pressure threshold value and the inter-stand liquid supply pipeline flow threshold value.

[0044] It should be noted that the type of failure is not limited in the present application. Optionally, the failure of the support liquid supply system can be a pipe burst failure or a working face leakage failure.

[0045] It should be noted that the pipe burst failure of the hydraulic support liquid supply system is often caused by the wear and tear of the liquid supply pipeline, the reduction of the pressure resistance level caused by the collision, and the like. When the high-pressure liquid pressure in the pipeline reaches the breaking pressure, the pipeline will burst or the pipeline seal will completely fail, causing the liquid in the pipeline to splash. Due to the pipeline covering or protective connection, some pipeline pipe bursts are not easy to observe, and in the unmanned automatic working face, the personnel have limited observation angle from the real-time video and cannot judge whether the hydraulic support liquid supply system fails.

[0046] In the embodiments of the present application, whether the hydraulic support liquid supply system fails can be judged according to the inter-stand liquid supply pipeline pressure, the inter-stand liquid supply pipeline flow, the inter-stand liquid supply pipeline pressure threshold value and the inter-stand liquid supply pipeline flow threshold value.

[0047] It should be noted that according to the inter-stand liquid supply pipeline pressure, the liquid supply pipeline pressures P1, P2, P3…, Pn of different stands can be obtained. When the hydraulic support liquid supply system fails, the inter-stand liquid supply pipeline pressure will be released at a certain moment, resulting in a sudden drop in pressure and the propagation of the pressure to both sides along the liquid inlet pipeline. At the same time, it will also cause the inter-stand liquid supply pipeline flow to abnormally increase.

[0048] Optionally, when the inter-stand liquid supply pipeline pressure of at least one stand is less than the inter-stand liquid supply pipeline pressure threshold value, and the inter-stand liquid supply pipeline flow of at least one stand is greater than the inter-stand liquid supply pipeline flow threshold value, it is judged that the hydraulic support liquid supply system fails.

[0049] It should be noted that the hydraulic support liquid supply system working face leakage failure is often due to static seal failure and seal pair failure. The static seal failure is mainly due to the breakage of the O-shaped sealing ring, which is common in high-pressure liquid supply pipeline sealing and hydraulic valve chamber sealing. The seal pair failure is mainly due to the damage or wear of the sealing parts, which is common in frequently operated hydraulic components. Due to the complexity and large scale of the fully mechanized working face pipeline system, pipeline leakage is inevitable. In related technologies, the leakage is mainly identified by artificial judgment of liquid leakage sound.

[0050] Optionally, when at least one of the inter-stand liquid supply pipeline pressures is less than the inter-stand liquid supply pipeline pressure threshold, and at least one of the inter-stand liquid supply pipeline flows is greater than the inter-stand liquid supply pipeline flow threshold, it is determined that the hydraulic support liquid supply system has a failure.

[0051] It should be noted that the working face leakage failure is often opened for a long time, and is often opened during maintenance.

[0052] Further, after determining that the hydraulic support liquid supply system has a failure, corresponding processing measures can be taken, such as closing the working face liquid inlet, controlling the oil cylinder to stop acting, etc., to reduce the safety hidden danger of the hydraulic support liquid supply system.

[0053] S104, determining that the hydraulic support liquid supply system has a failure, acquiring the action data of the hydraulic support, and positioning the failure position of the hydraulic support liquid supply system according to the inter-stand liquid supply pipeline pressure and the action data of the hydraulic support.

[0054] It should be noted that the hydraulic support liquid supply system failure is often caused by the action of the hydraulic support, such as moving the stand, pushing the slide, pushing the section, collecting the support, and stretching the support.

[0055] In the embodiments of the present application, after determining that the hydraulic support system has a failure, the action data of the hydraulic support can be acquired, and the failure position of the hydraulic support liquid supply system can be positioned according to the inter-stand liquid supply pipeline pressure and the action data of the hydraulic support.

[0056] The hydraulic support liquid supply system fault judgment and positioning method provided in the application collects the inter-support liquid supply pipeline pressure and the inter-support liquid supply pipeline flow to obtain the inter-support liquid supply pipeline pressure and the inter-support liquid supply pipeline flow; obtains the inter-support liquid supply pipeline pressure threshold and the inter-support liquid supply pipeline flow threshold; judges whether the hydraulic support liquid supply system has a fault according to the inter-support liquid supply pipeline pressure, the inter-support liquid supply pipeline flow, the inter-support liquid supply pipeline pressure threshold and the inter-support liquid supply pipeline flow threshold; determines that the hydraulic support liquid supply system has a fault, obtains the action data of the hydraulic support, and positions the fault position of the hydraulic support liquid supply system according to the inter-support liquid supply pipeline pressure and the action data of the hydraulic support. The application can accurately judge and position the fault of the liquid supply system, and can take corresponding processing measures after the fault occurs, thereby reducing the safety hidden danger of the hydraulic support liquid supply system.

[0057] It should be noted that, in the application, when judging whether the hydraulic support liquid supply system has a fault according to the inter-support liquid supply pipeline pressure, the inter-support liquid supply pipeline flow, the inter-support liquid supply pipeline pressure threshold and the inter-support liquid supply pipeline flow threshold, the following method can be used, that is, in response to the inter-support liquid supply pipeline pressure of at least one support in the inter-support liquid supply pipeline pressure being less than the inter-support liquid supply pipeline pressure threshold and the inter-support liquid supply pipeline flow of at least one support in the inter-support liquid supply pipeline flow being greater than the inter-support liquid supply pipeline flow threshold, it is judged that the hydraulic support liquid supply system has a fault.

[0058] The specific process of judging whether the hydraulic support liquid supply system has a fault according to the inter-support liquid supply pipeline pressure, the inter-support liquid supply pipeline flow, the inter-support liquid supply pipeline pressure threshold and the inter-support liquid supply pipeline flow threshold proposed in the application is explained below.

[0059] Optionally, in response to the inter-support liquid supply pipeline pressure of at least one support in the inter-support liquid supply pipeline pressure being less than the inter-support liquid supply pipeline pressure threshold and the inter-support liquid supply pipeline flow of at least one support in the inter-support liquid supply pipeline flow being greater than the inter-support liquid supply pipeline flow threshold, it is judged that the hydraulic support liquid supply system has a fault.

[0060] For example, when the inter-stand liquid supply pipeline pressure Pm of the mth stand in the inter-stand liquid supply pipeline pressure decreases to the inter-stand pipeline pressure threshold Pb, and the inter-stand liquid supply pipeline flow or the inter-stand liquid supply pipeline flow increases to the inter-stand liquid supply pipeline flow threshold Qgb, the inter-stand liquid supply pipeline pressure Pm-1 of the m-1th stand, the inter-stand liquid supply pipeline pressure Pm of the mth stand, the inter-stand liquid supply pipeline pressure Pm+1 of the m+1th stand, the inter-stand liquid supply pipeline flow Qgm-1 of the m-1th stand, the inter-stand liquid supply pipeline flow Qgm of the mth stand, and the inter-stand liquid supply pipeline flow Qgm+1 of the m+1th stand can be obtained in the next acquisition cycle. When Pm≤Pb, Pm-1≤Pb, Pm+1≤Pb, Qgm-1≥Qgb, Qgm≥Qgb, and Qgm+1≥Qgb, it can be judged that the hydraulic support system fails.

[0061] It should be noted that the inter-stand liquid supply pipeline pressure, the inter-stand liquid supply pipeline pressure threshold, the inter-stand liquid supply pipeline flow, and the inter-stand liquid supply pipeline flow threshold can also be used to judge whether the support system fails.

[0062] For example, when the inter-stand liquid supply pipeline pressure of at least one stand in the inter-stand liquid supply pipeline pressure is less than the inter-stand pipeline pressure threshold, and the inter-stand liquid supply pipeline flow of at least one stand in the inter-stand liquid supply pipeline flow is greater than the inter-stand liquid supply pipeline flow threshold, it is judged that the hydraulic support liquid supply system fails.

[0063] Further, the inter-stand liquid supply pipeline pressure and the inter-stand liquid supply pipeline flow of different stands of the hydraulic support can be continuously extracted, and then the above judgment method is used to judge whether the hydraulic support system fails.

[0064] The judgment and positioning method of the hydraulic support liquid supply system failure provided in the present application judges that the hydraulic support liquid supply system fails when the inter-stand liquid supply pipeline pressure of at least one stand in the inter-stand liquid supply pipeline pressure is less than the inter-stand liquid supply pipeline pressure threshold, and the inter-stand liquid supply pipeline flow of at least one stand in the inter-stand liquid supply pipeline flow is greater than the inter-stand liquid supply pipeline flow threshold. Therefore, the present application can judge whether the hydraulic support liquid supply system fails based on the inter-stand liquid supply pipeline pressure, the inter-stand liquid supply pipeline flow, the inter-stand liquid supply pipeline pressure threshold, and the inter-stand liquid supply pipeline flow threshold, thereby improving the accuracy and reliability of judging whether the hydraulic support system fails, and laying a foundation for reducing the safety hidden danger of the hydraulic support liquid supply system.

[0065] In the embodiments of the present application, when it is determined that the hydraulic support liquid supply system fails, the action data of the hydraulic support can be obtained, and the failure position of the hydraulic support liquid supply system is positioned according to the inter-stand liquid supply pipeline pressure and the action data of the hydraulic support.

[0066] As a possible implementation manner, as shown in Figure 2As shown, on the basis of the above embodiment, the specific process of locating the fault position of the hydraulic support liquid supply system according to the inter-aisle liquid supply pipeline pressure and the action data of the hydraulic support in step S104 includes the following steps:

[0067] S201, obtaining the support action times of the hydraulic support action data when the fault occurs.

[0068] It should be noted that the action type, action time, and action times of the hydraulic support can be obtained from the action data of the hydraulic support.

[0069] It should be noted that the fault of the hydraulic support liquid supply system is often caused by the action of the hydraulic support, and then the action times of the support action when the fault occurs can be obtained, for example, the actions of the hydraulic support such as moving the support, pushing the support, pushing the section, collecting the support, and extending the support.

[0070] S202, locating the fault position of the hydraulic support liquid supply system according to the inter-aisle liquid supply pipeline pressure and the support action times.

[0071] In the embodiment, after obtaining the inter-aisle liquid supply pipeline pressure and the support action times, the fault position of the hydraulic support liquid supply system can be located according to the inter-aisle liquid supply pipeline pressure and the support action times.

[0072] For example, the inter-aisle liquid supply pipeline pressure Pm-2 of the m-2 support, the inter-aisle liquid supply pipeline pressure Pm-1 of the m-1 support, the inter-aisle liquid supply pipeline pressure Pm of the m support, the inter-aisle liquid supply pipeline pressure Pm+1 of the m+1 support, and the inter-aisle liquid supply pipeline pressure Pm+2 of the m+2 support can be obtained, and when the above pressures are all less than the inter-aisle liquid supply pipeline pressure threshold, it can be judged that the fault occurs between the m support and the m+1 support in the hydraulic support liquid supply system, and if the support action times are the n support, and n is between (m, m+1), then the fault position of the hydraulic support liquid supply system is near the n support.

[0073] Further, when the plurality of inter-aisle liquid supply pipeline pressures drop to the inter-aisle liquid supply pipeline pressure threshold Pb, and the inter-aisle liquid supply pipeline flow rate rises to the inter-aisle liquid supply pipeline flow rate threshold Qgb, the inter-aisle liquid supply pipeline pressures of all the supports on the working face can be obtained, the two support times (x1, x2) with the lowest pressures first dropping and the two support times (x1', x2') with the lowest pressures after the fault can be obtained, if the above intervals are consistent, then the fault position of the hydraulic support liquid supply system is between the support times (x1, x2), and if the above intervals are inconsistent, then the fault position of the hydraulic support liquid supply system is between the support times (x1, x2) or (x1', x2').

[0074] In the embodiment of the present application, after determining that the hydraulic support system fails, a failure warning can be generated, and then the relevant personnel can be reminded to replace the inter-stand pipeline according to the failure warning.

[0075] Further, after determining that the hydraulic support liquid supply system fails, corresponding processing measures can be taken to reduce the safety hazards existing in the hydraulic support liquid supply system.

[0076] As a possible implementation manner, as shown in the figure, Figure 3 the specific process after determining that the hydraulic support liquid supply system fails in the above embodiment includes the following steps:

[0077] S301, the liquid supply system outputs a liquid path cutoff signal and a hydraulic support action stop signal.

[0078] It should be noted that the liquid path cutoff signal acts on the electro-hydraulic control liquid path cutoff valve of the liquid inlet main pipeline and the pump station power supply.

[0079] S302, according to the liquid path cutoff signal, the working face liquid inlet of the hydraulic support liquid supply system is controlled to be closed, and according to the hydraulic support action stop signal, the oil cylinder of the hydraulic support liquid supply system is controlled to stop action.

[0080] It should be noted that after the liquid path cutoff signal acts on the electro-hydraulic control liquid path cutoff valve of the liquid inlet main pipeline, the working face liquid inlet can be controlled to be closed, or the liquid path cutoff signal acts on the pump station power supply to control the liquid supply to be closed, thereby realizing the control of closing the working face liquid inlet of the hydraulic support liquid supply system.

[0081] It should be noted that after the hydraulic support action stop signal acts on the electro-hydraulic control system, the oil cylinder of the hydraulic support can be controlled to stop action.

[0082] The judgment and positioning method of the hydraulic support liquid supply system failure provided in the present application, after determining that the hydraulic support liquid supply system fails, the liquid supply system outputs a liquid path cutoff signal and a hydraulic support action stop signal, according to the liquid path cutoff signal, the working face liquid inlet of the hydraulic support liquid supply system is controlled to be closed, and according to the hydraulic support action stop signal, the oil cylinder of the hydraulic support liquid supply system is controlled to stop action, thereby, after the hydraulic support control system fails, corresponding processing measures can be taken to reduce the safety hazards caused by the failure, and the production efficiency of the coal mine is ensured.

[0083] The process of the judgment and positioning method of the hydraulic support liquid supply system failure provided in the present application will be explained and described below.

[0084] For example, as shown in the figure, Figure 4As shown, the hydraulic support liquid supply system fault judgment and positioning method provided in the present application is divided into a data acquisition layer, a judgment control layer and an action execution layer. The inter- support liquid supply pipeline pressure and the inter- support liquid supply pipeline flow are collected, and the inter- support liquid supply pipeline pressure threshold and the inter- support liquid supply pipeline flow threshold are combined to judge whether the pipe burst fault and the leakage fault occur. Further, the inter- support liquid supply pipeline pressure and the support action data when the fault occurs are collected to locate the fault position of the hydraulic support liquid supply system. Further, after the hydraulic support liquid supply system fails, corresponding treatment measures can be taken to reduce the safety hazards existing in the hydraulic support liquid supply system, such as setting a high- pressure pipeline pressure relief valve, etc. After the pipe burst phenomenon occurs, warning output is performed, high- pressure liquid relief is executed, hydraulic support action is stopped, and the high- pressure emulsion pump station is shut down, etc. Treatment measures are taken to reduce the harm of pipe burst.

[0085] In summary, the hydraulic support liquid supply system fault judgment and positioning method provided in the present application collects the inter- support liquid supply pipeline pressure and the inter- support liquid supply pipeline flow to obtain the inter- support liquid supply pipeline pressure and the inter- support liquid supply pipeline flow. The inter- support liquid supply pipeline pressure threshold and the inter- support liquid supply pipeline flow threshold are obtained. According to the inter- support liquid supply pipeline pressure, the inter- support liquid supply pipeline flow, the inter- support liquid supply pipeline pressure threshold and the inter- support liquid supply pipeline flow threshold, it is judged whether the hydraulic support liquid supply system fails. When the hydraulic support liquid supply system fails, the action data of the hydraulic support is obtained. According to the inter- support liquid supply pipeline pressure and the action data of the hydraulic support, the fault position of the hydraulic support liquid supply system is located. Thus, based on the inter- support liquid supply pipeline pressure, the inter- support liquid supply pipeline flow, the inter- support liquid supply pipeline pressure threshold and the inter- support liquid supply pipeline flow threshold, the fault of the liquid supply system is judged and positioned, the accuracy and reliability of judging the fault of the liquid supply system are improved, and after the hydraulic support liquid supply system fails, corresponding treatment measures can be taken to reduce the safety hazards existing in the hydraulic support liquid supply system, and the production efficiency of the coal mine is ensured.
