Description

Technical Field

[0001] The present application relates to the field of building foundation pit support systems, and in particular to a composite diagonal bracing pile support method, system, storage medium and intelligent terminal. Background Art

[0002] With the development of national economic construction, the construction of underground space has become more and more frequent, and the construction technology of foundation pit support system, which is used to support, reinforce and protect underground space, has also made great progress. In recent years, in order to avoid exceeding the red line of construction projects, relevant policies have prohibited the use of soil anchor support for deep foundation pits in soft soil; and the cost of using retaining piles plus horizontal inward support is relatively high; therefore, the combined support form of retaining piles, top beams and inclined support piles in the foundation pit has been increasingly widely used.

[0003] The diagonal brace piles are composed of combined diagonal piles extending under the foundation pit floor and steel pipe diagonal braces located above the foundation pit floor; the upper end of the steel pipe diagonal brace is against the top pressure beam, and the lower end of the steel pipe diagonal brace is supported on the upper end of the combined diagonal piles; the combined diagonal piles are composed of a precast concrete square pile in the center and a cement soil pile wrapped on the outside.

[0004] The following problems exist in the prior art: since the bottom of the foundation pit is a soil area, the diagonal support piles are in a stressed state for a long time, which promotes the sinking of the diagonal support piles, resulting in insufficient supporting force of the diagonal support piles on the top crown beam corbels, and they cannot play a supporting role. There is still room for improvement. Summary of the invention

[0005] In order to improve the problem that the diagonal bracing piles are in a stressed state for a long time, which promotes the sinking of the diagonal bracing piles, resulting in insufficient supporting force of the diagonal bracing piles on the corbels of the top crown beams and inability to play a supporting role, the present application provides a composite diagonal bracing pile support method, system, storage medium and intelligent terminal.

[0006] In the first aspect, the present application provides a composite diagonal bracing pile support method, which adopts the following technical solution: A composite diagonal bracing pile supporting method, comprising: Obtaining the supporting axial force of the inclined support pile on the supporting device, the supporting device includes an inclined support pile obliquely inserted into the bottom plate of the foundation pit and a hydraulic station on one side of the foundation pit, the inclined support pile is coaxially provided with a plurality of hydraulic jacks abutting against the corbel of the capping crown beam, the hydraulic jacks and the hydraulic station are interconnected so that the hydraulic oil flows between the hydraulic jacks and the hydraulic station; When the supporting axial force does not fall within the preset stable supporting force range, the axial force deviation direction is determined based on the supporting axial force and the stable supporting force range; Determine the hydraulic oil flow direction based on the axial force deviation direction; Control the hydraulic station to transmit hydraulic oil according to the hydraulic oil flow direction and obtain the supporting shaft force in real time; When the supporting shaft force is equal to the preset appropriate supporting force, the control hydraulic station stops working.

[0007] By adopting the above technical solution, the supporting axial force of the diagonal support pile is detected to determine whether the diagonal support pile sinks. If it sinks, oil is automatically used in the hydraulic station to compensate until the supporting axial force reaches the required value, thereby ensuring the stability of the supporting axial force and improving the controllability of the supporting axial force and the support stability.

[0008] Optionally, the method of controlling the hydraulic station to transmit the hydraulic oil according to the hydraulic oil flow direction includes: Get the amount of hydraulic oil in the hydraulic jack; Based on the hydraulic oil volume and the supporting shaft force, the corresponding supplementary oil volume is found from the preset standard database; Correcting the preset speed-time curve based on the amount of supplementary oil to obtain a corrected speed-time curve; The hydraulic station is controlled to transmit the hydraulic oil according to the hydraulic oil flow direction, and at the same time, the speed of the hydraulic oil transmission is controlled according to the modified speed-time curve, and the supplementary oil amount and the modified speed-time curve are continuously analyzed.

[0009] By adopting the above technical scheme, the oil injection speed is first controlled to increase slowly, then slowly decrease, and finally the oil injection speed is zero when the oil is full. On the one hand, the initial speed is slow, which avoids the unstable situation of oil overflow caused by rapid injection, thereby improving the stability of oil injection; on the other hand, the middle speed is relatively large, which reduces the oil injection time and improves the oil injection efficiency when the oil injection process is stable; finally, the final speed is relatively small, so that the final stop will not produce bubbles.

[0010] Optionally, the method further includes controlling the hydraulic station to control the transmission of the hydraulic oil according to the hydraulic oil circulation direction when the hydraulic oil circulation direction is a preset oil-increasing direction, the method comprising: Get viscosity requirements; Based on the viscosity requirement, the corresponding suitable viscosity is found from the preset characteristic database; The oil in the hydraulic jack is controlled to be detected by a preset pressure drop device to obtain the actual viscosity inside the jack, wherein the pressure drop device comprises an oil pipe, pressure sensors are arranged at both ends of the oil pipe, and a flow meter is arranged inside the oil pipe; The oil in the control hydraulic station is tested by a pressure drop device to obtain the actual viscosity in the station, wherein the hydraulic station is provided with a circulating oil tank, a high-viscosity oil tank and a low-viscosity oil tank, wherein the actual viscosity in the station is the viscosity of the hydraulic oil in the circulating oil tank, wherein the high-viscosity oil tank contains a preset high-viscosity hydraulic oil, and wherein the low-viscosity oil tank contains a preset low-viscosity hydraulic oil; When the actual top viscosity does not match the appropriate viscosity, the actual supplementary oil quantity is determined based on the supplementary oil quantity and the hydraulic oil quantity; Calculate and determine the mix ratio based on actual in-station viscosity, suitable viscosity, high viscosity and low viscosity; Control the hydraulic jack to discharge the hydraulic oil into the circulating oil tank after passing through the preset filtering system, and then control the hydraulic oil in the hydraulic station to proportion the hydraulic oil according to the proportioning scheme, and finally control the transmission of the proportioned hydraulic oil; When the actual top viscosity matches the appropriate viscosity, the hydraulic oil in the hydraulic station is controlled to be proportioned according to the proportioning plan, and then the hydraulic station is controlled to transmit the hydraulic oil according to the flow direction of the hydraulic oil.

[0011] By adopting the above technical solution, when the internal viscosity is different from the required viscosity, it means that the hydraulic oil does not meet the requirements. At this time, it is necessary to mix hydraulic oil with corresponding viscosity from the hydraulic station to ensure the corresponding viscosity and the viscosity inside the hydraulic jack.

[0012] Optionally, the method for calculating and determining the proportioning scheme based on the actual in-station viscosity, suitable viscosity, high viscosity and low viscosity includes: Get the oil usage time in the station; When the oil usage time in the station exceeds the preset service life, the oil in the circulating oil tank will be directly discharged to the preset waste area, and the proportioning scheme will be calculated and determined based on the appropriate viscosity, high viscosity and low viscosity; When the service life of the oil in the station is less than the preset service life, the flow relationship between the oil flow in the station, the high viscosity oil flow and the low viscosity oil flow is obtained based on the ratio scheme; Analyze the flow relationship to obtain the maximum value of the oil flow in the station, and define this value as the maximum oil flow in the station; The mixing ratio is calculated and determined based on the maximum oil flow rate within the station, the actual viscosity within the station, the appropriate viscosity, the high viscosity and the low viscosity.

[0013] By adopting the above technical solution, when the oil in the circulating oil tank is of poor quality due to long-term use, it is discharged and replaced with new oil, thereby ensuring the quality of the hydraulic oil; on the other hand, if the oil in the circulating oil tank is of good quality, the oil in the circulating oil tank is used as much as possible to avoid wasting new oil and save material costs.

[0014] Optionally, when the actual top viscosity matches the appropriate viscosity, after the hydraulic oil in the hydraulic station is controlled to be proportioned according to the proportioning scheme, the method of controlling the hydraulic station to transmit the hydraulic oil according to the hydraulic oil flow direction includes: Determine the actual oil flow rate, actual high-viscosity oil volume and actual low-viscosity oil volume in the station based on the proportioning scheme; Determine the first theoretical viscosity based on the appropriate viscosity, hydraulic oil volume, low viscosity and actual low viscosity oil flow rate; Determine the second theoretical viscosity based on the first theoretical viscosity, the hydraulic oil volume, the actual low-viscosity oil flow, the actual station viscosity and the actual station oil flow; When the actual oil flow in the station exists, the hydraulic oil in the low-viscosity oil tank in the hydraulic station is controlled to flow into the hydraulic jack according to the actual low-viscosity oil flow, and the hydraulic oil in the hydraulic jack is tested through a pressure drop device to obtain the first supplementary viscosity; When the first supplementary viscosity is different from the first theoretical viscosity, continue to test through the pressure drop device until the first supplementary viscosity is the same as the first theoretical viscosity; When the first supplementary viscosity is the same as the first theoretical viscosity, the hydraulic oil in the circulating oil tank in the hydraulic station is controlled to flow into the hydraulic jack according to the actual oil flow in the station, and the hydraulic oil in the hydraulic jack is tested through a pressure drop device to obtain the second supplementary viscosity; When the second supplementary viscosity is different from the second theoretical viscosity, continue to test through the pressure drop device until the second supplementary viscosity is the same as the second theoretical viscosity; When the second supplementary viscosity is the same as the second theoretical viscosity, the hydraulic oil in the high viscosity oil tank in the hydraulic station is controlled to flow into the hydraulic jack according to the actual high viscosity oil volume, and the hydraulic oil in the hydraulic jack is tested through a pressure drop device to obtain the third supplementary viscosity; When the third supplementary viscosity is different from the suitable viscosity, continue to test through the pressure drop device until the third supplementary viscosity is the same as the suitable viscosity; Stop oiling when the viscosity is equal to the appropriate viscosity after the third replenishment.

[0015] By adopting the above technical solution, the proportioned oil is first mixed into the low-viscosity oil, so that the oil is more fluent and mixing is more convenient, thereby improving the efficiency of hydraulic oil mixing.

[0016] Optionally, when the actual jack internal viscosity does not match the appropriate viscosity, the method of controlling the hydraulic jack to discharge the hydraulic oil into the circulating oil tank after passing through the filtering system includes: The hydraulic oil in the hydraulic jack passes through the filter system and then passes through the pressure drop device for testing to obtain the actual viscosity inside the filter jack; When the actual viscosity in the filter top matches the appropriate viscosity, the hydraulic oil after the filtration system flows back to the hydraulic jack and controls the hydraulic oil in the hydraulic station to mix the hydraulic oil according to the ratio scheme, and then transmits the hydraulic oil according to the flow direction of the hydraulic oil; When the actual viscosity inside the filter top matches the high viscosity, the hydraulic oil after passing through the filter system is controlled to be discharged into the high viscosity oil tank; When the actual viscosity inside the filter top matches the low viscosity, the hydraulic oil after passing through the filter system is controlled to be discharged into the low viscosity oil tank; When the actual viscosity in the filter top and the actual viscosity in the station, high viscosity and low viscosity do not match, the viscosity deviation value is calculated based on the actual viscosity in the filter top and the actual viscosity in the station; When the viscosity deviation value falls into the preset unreasonable deviation range, the hydraulic oil after passing through the filtration system is controlled to be directly discharged to the preset waste area; When the viscosity deviation value does not fall into an unreasonable deviation range, the hydraulic oil after passing through the filtration system is controlled to be discharged into the circulating oil tank.

[0017] Optionally, when the viscosity deviation value falls into an unreasonable deviation range, the method of controlling the hydraulic oil after passing through the filtration system to be directly discharged to the waste area includes: Determine the adjustment viscosity range based on the actual filter top viscosity, high viscosity and low viscosity; When the adjustment viscosity range and the preset reasonable deviation range partially overlap, determining the overlapping range; Determine the trim oil amount corresponding to the high-viscosity or low-viscosity hydraulic oil based on the overlap range, the actual filter top viscosity, the hydraulic oil amount, the high viscosity and the low viscosity, define the trim oil amount corresponding to the high-viscosity hydraulic oil as the high-viscosity trim oil amount, and define the trim oil amount corresponding to the low-viscosity hydraulic oil as the low-viscosity trim oil amount; When the amount of high-viscosity trim oil or low-viscosity trim oil exceeds the preset reasonable critical oil amount value, the hydraulic oil after passing through the filtration system is controlled to be directly discharged to the waste area; When the amount of high-viscosity trim oil or low-viscosity trim oil is lower than a reasonable critical oil amount, the hydraulic oil after passing through the filtration system is controlled to be discharged into the circulating oil tank, and the high-viscosity oil tank or low-viscosity oil tank is discharged into the circulating oil tank according to the corresponding amount of high-viscosity trim oil or the corresponding amount of low-viscosity trim oil, and then the contents of the circulating oil tank are mixed evenly.

[0018] By adopting the above technical solution, if the filtered oil is directly discharged because of its large viscosity difference, we can first check whether it can be optimized by low-viscosity oil or high-viscosity oil, that is, viscosity adjustment. If it can be done, it can be added to the circulating oil tank. If not, it can be discharged directly, saving material costs.

[0019] In the second aspect, the present application provides a composite diagonal bracing pile support system, which adopts the following technical solution: A composite diagonal bracing pile support system, comprising: The acquisition module is used to obtain the support shaft force, hydraulic oil volume, current temperature, actual top viscosity, actual station viscosity and station oil usage time; A memory for storing a program of a control method of any of the above-mentioned composite diagonal bracing pile supporting methods; The program in the processor memory can be loaded and executed by the processor to implement any of the above-mentioned control methods of the composite inclined bracing pile support method.

[0020] By adopting the above technical solution, the supporting axial force of the diagonal support pile is detected to determine whether the diagonal support pile sinks. If it sinks, oil is automatically used in the hydraulic station to compensate until the supporting axial force reaches the required value, thereby ensuring the stability of the supporting axial force and improving the controllability of the supporting axial force and the support stability.

[0021] In the third aspect, the present application provides a smart terminal, which adopts the following technical solution: The intelligent terminal comprises a memory and a processor, wherein the memory stores a computer program which can be loaded by the processor and execute any one of the composite bracing pile supporting methods.

[0022] By adopting the above technical solution, the supporting axial force of the diagonal support pile is detected to determine whether the diagonal support pile sinks. If it sinks, oil is automatically used in the hydraulic station to compensate until the supporting axial force reaches the required value, thereby ensuring the stability of the supporting axial force and improving the controllability of the supporting axial force and the support stability.

[0036] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 9 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0037] The present application embodiment discloses a composite diagonal bracing pile support method. Figure 1 A composite diagonal bracing pile support method comprises: Step 100: Obtain the supporting axial force of the diagonal bracing piles on the supporting device.

[0038] The support device includes a diagonal support pile and a hydraulic station. The diagonal support pile is inserted obliquely into the bottom plate of the foundation pit, and a number of hydraulic jacks are coaxially fixedly installed on the diagonal support pile. The hydraulic jacks abut against the corbels of the crown beam to support the corbels of the crown beam. The hydraulic station is on one side of the foundation pit, and the hydraulic jacks and the hydraulic station are connected to each other so that the hydraulic oil can flow between the hydraulic jacks and the hydraulic station.

[0039] The supporting axial force is the supporting force of the diagonal bracing pile against the corbel of the capping beam, which can be obtained by arranging a pressure sensor at the end of the hydraulic jack away from the diagonal bracing pile.

[0040] Step 101: When the supporting axial force does not fall within a preset stable supporting force range, determining the axial force deviation direction based on the supporting axial force and the stable supporting force range.

[0041] The stable support force range is the reasonable range of the support force of the diagonal bracing pile on the upper corbel, which can be measured manually according to the actual situation, that is, within this range, the corbel and the pile row will basically not collapse. The axial force deviation direction is the direction of the deviation between the support axial force and the stable support force range, that is, the positive and negative values. If the support axial force is less than the stable support force range, the axial force deviation direction is negative, and vice versa.

[0042] Step 102: Determine the hydraulic oil flow direction based on the axial force deviation direction.

[0043] The hydraulic oil flow direction is the direction of the hydraulic oil flow. The determination method is that if the axial force deviation direction is negative, the hydraulic oil flow direction is the hydraulic station supplying oil to the hydraulic jack, and if the axial force deviation direction is positive, the hydraulic oil flow direction is the hydraulic station pumping oil from the hydraulic jack.

[0044] Step 103: Control the hydraulic station to transmit the hydraulic oil according to the hydraulic oil flow direction and obtain the supporting shaft force in real time.

[0045] Step 104: When the supporting shaft force is equal to the preset appropriate supporting force, the hydraulic station is stopped from operating.

[0046] The suitable supporting force is a suitable supporting force within the range of stable supporting force. At this supporting force, the machine will not easily deviate from the range of stable supporting force and work frequently.

[0047] Reference Figure 3 The method of controlling the hydraulic station to transmit the hydraulic oil according to the hydraulic oil flow direction includes: Step 200: Obtain the amount of hydraulic oil in the hydraulic jack.

[0048] The hydraulic oil volume is the amount of hydraulic oil in the hydraulic jack. It can be obtained by obtaining the depth through a depth gauge and then multiplying it by the size of the hydraulic jack. It can also be obtained by obtaining the inlet and outlet flow through the inlet and outlet flow meters and then calculating.

[0049] Step 201: Based on the hydraulic oil volume and the supporting shaft force, the corresponding supplementary oil volume is searched from a preset standard database.

[0050] The supplementary oil volume is the hydraulic oil that needs to be added to reach the appropriate supporting force based on the supporting shaft force. The database stores the mapping relationship between the hydraulic oil volume, supporting shaft force and supplementary oil volume. The staff in this field records the internal hydraulic oil volume and supporting shaft force according to the actual situation of the hydraulic jack, and then starts to add oil until the supporting shaft force is equal to the appropriate supporting force, and then stops adding oil. The amount of oil added is counted, and this amount of oil is the supplementary oil volume.

[0051] Step 202: Correcting the preset speed-time curve based on the amount of supplementary oil to obtain a corrected speed-time curve.

[0052] The speed-time curve is a curve of speed and time. Here, the horizontal axis of the curve is time, the vertical axis is speed, and the entire area is the total oil volume. In addition, the speed of the curve gradually increases with time at the beginning, and then gradually decreases when it reaches the peak, which is similar to the cosine function curve. The corrected speed-time curve is the speed-time curve corrected according to the amount of supplementary oil. Here, the entire corrected area is the amount of supplementary oil. The correction method is to take the area enclosed by the speed-time curve and the horizontal axis as a unit size, and then enlarge or reduce it proportionally according to the amount of supplementary oil.

[0053] Step 203: Control the hydraulic station to transmit the hydraulic oil according to the hydraulic oil flow direction and control the speed of the hydraulic oil transmission according to the modified speed-time curve, and continue to analyze to obtain the replenishment oil amount and the modified speed-time curve.

[0054] The purpose of controlling the speed of hydraulic oil transmission according to the modified speed-time curve is, firstly, that the initial speed is slow to avoid the unstable situation of oil overflow caused by rapid injection, thereby improving the stability of oil injection; on the other hand, the middle speed is relatively large to reduce the oil injection time and improve the oil injection efficiency under the condition of stable oil injection process; finally, the final speed is relatively small, so that there will be no sudden stop and bubbles generated.

[0055] Reference Figure 4 , and also includes a method for controlling the hydraulic station to transmit the hydraulic oil according to the hydraulic oil flow direction when the hydraulic oil flow direction is a preset oil increase direction, the method comprising: Step 300: Obtain viscosity requirement.

[0056] The viscosity requirement is the viscosity requirement of the hydraulic oil in the current hydraulic jack. It can be obtained by recording the characteristics of the supporting force and internal viscosity. For example, in order to achieve a certain supporting force, the viscosity of the internal hydraulic oil needs to be a certain amount, and it usually changes according to the temperature. High-viscosity oil is thicker at low temperatures, which increases the flow resistance and may cause difficulty in starting the equipment or require more power when starting; low-viscosity oil tends to become thinner at high temperatures and cannot form an effective oil film between moving parts, resulting in insufficient lubrication and accelerated wear.

[0057] Step 301: searching for a corresponding suitable viscosity from a preset characteristic database based on the viscosity requirement.

[0058] The appropriate viscosity is the viscosity for normal operation. The mapping relationship between viscosity requirements and appropriate viscosity is stored in the characteristic database. Inappropriate oil viscosity usually means that the oil viscosity used in the hydraulic system does not match the working conditions of the equipment, which may affect the normal operation of the hydraulic system. It is designed by the staff in this field based on actual experience and experiments. When the system receives the corresponding viscosity requirement, it automatically finds the corresponding appropriate viscosity from the database.

[0059] Step 302: Control the oil in the hydraulic jack to pass through a preset pressure drop device for detection to obtain the actual viscosity inside the jack.

[0060] The pressure drop device includes an oil pipe, and pressure sensors are provided at both ends of the oil pipe to detect the oil pressure of the hydraulic oil passing through the part. A flow meter is provided inside the oil pipe to detect the flow rate.

[0061] The actual internal viscosity is the viscosity of the hydraulic oil in the actual hydraulic jack. The purpose of setting the pressure drop device here is to use the pressure drop method to detect the viscosity of the fluid. The basic principle of the pressure drop method is that when the fluid flows in the pipeline, due to the friction between the fluid and the pipeline wall and the internal friction (i.e. viscosity) inside the fluid, a certain pressure loss will be generated. According to the theory of fluid mechanics, this pressure loss is related to factors such as the viscosity of the fluid, the flow rate, and the geometric dimensions of the pipeline (such as diameter and length). For laminar flow conditions (Reynolds number Re<2100), the Poiseuille equation can be used; for turbulent flow conditions, the Darcy-Weisbach equation is usually used.

[0062] Step 303: Control the oil in the hydraulic station to pass through the pressure drop device for detection to obtain the actual viscosity in the station.

[0063] The hydraulic station has a circulating oil tank, a high-viscosity oil tank and a low-viscosity oil tank. The actual viscosity in the station is the viscosity of the hydraulic oil in the circulating oil tank. The high-viscosity oil tank contains high-viscosity hydraulic oil. The high viscosity is a certain set viscosity value. The low-viscosity oil tank contains low-viscosity hydraulic oil. The low viscosity is a certain set viscosity value. The high viscosity is greater than the low viscosity.

[0064] Step 304: When the actual top viscosity does not match the appropriate viscosity, determine the actual supplementary oil amount based on the supplementary oil amount and the hydraulic oil amount.

[0065] The actual amount of oil to be replenished is the amount of oil that actually needs to be replenished. Here, the amount of oil is the sum of the replenished oil amount and the hydraulic oil amount. When the actual top viscosity does not match the appropriate viscosity, it means that the internal hydraulic oil does not meet the oil quality, so the internal hydraulic oil is discharged, and then the required viscosity is re-proportioned. Therefore, in addition to the replenished oil amount, the hydraulic oil amount needs to be replenished.

[0066] Step 305: Calculate and determine the mixing ratio based on the actual in-station viscosity, suitable viscosity, high viscosity and low viscosity.

[0067] The proportioning scheme is to mix the oil in the circulating oil tank, high viscosity oil tank and low viscosity oil tank to obtain a hydraulic oil with a suitable viscosity. Here are two three-variable linear equations, so the mapping relationship between the three will be obtained. Any scheme that can be established by the three can be taken, or the steps in the subsequent process can be taken to determine, which will not be repeated here.

[0068] Step 306: Control the hydraulic jack to discharge the hydraulic oil into the circulating oil tank after passing through a preset filtering system, and then control the hydraulic oil in the hydraulic station to proportion the hydraulic oil according to the proportioning scheme, and finally control the transmission of the proportioned hydraulic oil.

[0069] The filtration system is a system for filtering impurities, and it can be in the form of any kind of filter net.

[0070] Step 307: When the actual top viscosity matches the appropriate viscosity, the hydraulic oil in the hydraulic station is controlled to be proportioned according to the proportioning scheme, and then the hydraulic station is controlled to transmit the hydraulic oil according to the hydraulic oil flow direction.

[0071] When they match, it means that the hydraulic oil in the hydraulic jack can continue to be used, and you only need to replenish the hydraulic oil.

[0072] Reference Figure 5 , the method of calculating and determining the proportioning scheme based on the actual in-station viscosity, suitable viscosity, high viscosity and low viscosity includes: Step 400: Obtain the oil usage time in the station.

[0073] The usage time of the oil in the station is the existence time of the oil in the circulating oil tank. It should be noted here that the oil in the circulating oil tank is the same as the oil in the hydraulic jack. Normally, the oil in the circulating oil tank is circulated between the two, so the oil in the circulating oil tank is basically the hydraulic oil in use, which is easy to deteriorate. The oil in the high-viscosity oil tank and the low-viscosity oil tank is basically not in use and basically belongs to the situation of output without input. It is not easy to deteriorate, so it is only necessary to obtain the usage time of the oil in the station. Here, the cumulative time starts from the initial existence of oil in the circulating oil tank to ensure the quality of the oil in the tank.

[0074] Step 401: When the usage time of the oil in the station is longer than the preset service life, the oil in the circulating oil tank is directly discharged to the preset waste area, and the mixing ratio is calculated and determined based on the appropriate viscosity, high viscosity and low viscosity.

[0075] The service life is the service life of the hydraulic oil, which is obtained by the staff based on their own experience and observation of actual conditions. The waste area is the area for recycling waste oil. When the oil usage time in the station is longer than the service life, it means that the oil in the circulating oil tank can no longer be used, so the oil in the circulating oil tank is directly discharged to the waste area. At this time, it means that the circulating oil tank no longer provides hydraulic oil, and can only be supplied by the high-viscosity oil tank and the low-viscosity oil tank.

[0076] Step 402: When the usage time of the oil in the station is less than the preset service life, an analysis is performed based on the ratio scheme to obtain the flow relationship between the oil flow in the station, the high viscosity oil flow and the low viscosity oil flow.

[0077] The flow relationship is the relationship between the oil flow rate, high viscosity oil flow rate and low viscosity oil flow rate within the station.

[0078] When the usage time of the oil in the station is less than the service life, it means that the hydraulic oil in the circulating oil tank can be used for oil supply. Therefore, the flow relationship can be obtained at this time to determine the range of all flow rates.

[0079] Step 403: Analyze the flow relationship to obtain the maximum value of the oil flow in the station, and define this value as the maximum oil flow in the station.

[0080] The analysis method is to set any low-viscosity oil flow or high-viscosity oil flow to 0, then calculate the oil flow in the station respectively, and finally take the larger value of the two results.

[0081] Step 404: Calculate and determine a mixing ratio based on the maximum in-station oil flow, actual in-station viscosity, suitable viscosity, high viscosity and low viscosity.

[0082] When the maximum oil flow rate in the station is obtained, the other non-zero low-viscosity oil flow rate or high-viscosity oil flow rate is also determined, so the ratio scheme can be directly determined. When the amount of hydraulic oil in the circulating oil tank is the largest, the oil already in use in the circulating oil tank can be used as much as possible.

[0083] Reference Figure 6 When the actual top viscosity matches the appropriate viscosity, the method of controlling the hydraulic oil in the hydraulic station to mix the hydraulic oil according to the ratio scheme and then controlling the hydraulic station to transmit the hydraulic oil according to the hydraulic oil flow direction includes: Step 500: Determine the actual in-station oil flow, the actual high-viscosity oil volume, and the actual low-viscosity oil volume based on the proportioning scheme.

[0084] The actual oil flow rate in the station is the oil flow rate in the station in the final determined mixing scheme. The actual high viscosity oil volume is the high viscosity oil volume in the final determined mixing scheme. The actual low viscosity oil volume is the low viscosity oil volume in the final determined mixing scheme. The determination method here has been explained in the above steps 400-404 and will not be repeated here.

[0085] Step 501: Determine the first theoretical viscosity based on the appropriate viscosity, hydraulic oil volume, low viscosity and actual low viscosity oil flow rate.

[0086] The first theoretical viscosity is the theoretical viscosity of the oil already in the hydraulic jack and the oil in the low-viscosity oil tank after mixing. The calculation method is to multiply the appropriate viscosity by the hydraulic oil volume, the low viscosity by the actual low-viscosity oil flow, and the sum of the products divided by the sum of the hydraulic oil volume and the actual low-viscosity oil flow.

[0087] Step 502: Determine the second theoretical viscosity based on the first theoretical viscosity, the hydraulic oil volume, the actual low-viscosity oil flow, the actual in-station viscosity and the actual in-station oil flow.

[0088] The second theoretical viscosity is the theoretical viscosity of the hydraulic oil in the hydraulic jack after it is mixed with the oil in the low-viscosity oil tank and then mixed with the oil in the high-viscosity oil tank. The calculation method here is to multiply the sum of the hydraulic oil volume and the actual low-viscosity oil flow by the first theoretical viscosity, the viscosity in the station and the actual oil flow in the station, and the sum of the products of the two divided by the sum of the hydraulic oil volume, the actual low-viscosity oil flow and the actual oil flow in the station.

[0089] Step 503: When the actual oil flow in the station exists, the hydraulic oil in the low-viscosity oil tank in the hydraulic station is controlled to flow into the hydraulic jack according to the actual low-viscosity oil flow, and the hydraulic oil in the hydraulic jack is tested through a pressure drop device to obtain the first supplementary viscosity.

[0090] The first replenishment viscosity is the viscosity of the mixed oil after the hydraulic oil in the low viscosity oil tank in the hydraulic station flows into the hydraulic jack according to the actual low viscosity oil flow rate. There are two purposes for testing through the pressure drop device here, one is to detect the viscosity, and the other is to mix the two.

[0091] The purpose of adding the hydraulic oil in the low-viscosity oil tank first is to reduce the viscosity of the mixed oil, thereby making it more fluid and easier to mix later.

[0092] Step 504: When the first supplementary viscosity is different from the first theoretical viscosity, continue to test through the pressure drop device until the first supplementary viscosity is the same as the first theoretical viscosity.

[0093] The first supplementary viscosity is different from the first theoretical viscosity, indicating that the mixing is not sufficient at this time, and then continue to pass through the pressure drop device to continue mixing.

[0094] Step 505: When the first supplementary viscosity is the same as the first theoretical viscosity, the hydraulic oil in the circulating oil tank in the hydraulic station is controlled to flow into the hydraulic jack according to the actual oil flow in the station, and the hydraulic oil in the hydraulic jack is tested through a pressure drop device to obtain a second supplementary viscosity.

[0095] The second supplementary viscosity is the viscosity when the low viscosity oil is added to the hydraulic jack first and then the hydraulic oil in the circulating oil tank is added. If they are the same, it means that the mixing is complete and the hydraulic oil in the circulating oil tank can be mixed, and then the mixing is checked to see if it is complete.

[0096] Step 506: When the second supplementary viscosity is different from the second theoretical viscosity, continue to test through the pressure drop device until the second supplementary viscosity is the same as the second theoretical viscosity.

[0097] The difference between the second supplementary viscosity and the second theoretical viscosity indicates that the mixing is not sufficient at this time, so it continues to pass through the pressure drop device to continue mixing.

[0098] Step 507: When the second supplementary viscosity is the same as the second theoretical viscosity, the hydraulic oil in the high viscosity oil tank in the hydraulic station is controlled to flow into the hydraulic jack according to the actual high viscosity oil volume, and the hydraulic oil in the hydraulic jack is tested through a pressure drop device to obtain the third supplementary viscosity.

[0099] The third supplementary viscosity is the viscosity when the low viscosity oil is added to the hydraulic jack first, then the hydraulic oil in the circulating oil tank, and finally the high viscosity oil is added. If they are the same, it means that the mixing is complete, and the hydraulic oil in the high viscosity oil tank can be mixed, and then check whether the mixing is complete.

[0100] Step 508: When the third supplementary viscosity is different from the suitable viscosity, continue to test through the pressure drop device until the third supplementary viscosity is the same as the suitable viscosity.

[0101] If the third supplementary viscosity is different from the appropriate viscosity, it means that the mixing is not sufficient at this time, and then continue to pass through the pressure drop device to continue mixing.

[0102] The purpose of comparison with the optimum viscosity here is that the final viscosity should be the optimum viscosity in theory.

[0103] Step 509: Stop oil injection when the third supplementary viscosity is the same as the appropriate viscosity.

[0104] When the third supplementary viscosity is the same as the suitable viscosity, it means that the mixing is complete and the viscosity requirement of the suitable viscosity has been reached.

[0105] Reference Figure 7 When the actual viscosity inside the jack does not match the appropriate viscosity, the method of controlling the hydraulic jack to discharge the hydraulic oil into the circulating oil tank after passing through the filtering system includes: Step 600: After the hydraulic oil in the hydraulic jack passes through the filtering system, it passes through the pressure drop device again for detection to obtain the actual viscosity in the filter jack.

[0106] The actual viscosity of the filter top is the annual viscosity of the hydraulic oil in the hydraulic jack after passing through the filter system and then passing through the pressure drop device for detection. The purpose of passing through the filter system here is to remove some impurities.

[0107] Step 601: When the actual viscosity in the filter top matches the appropriate viscosity, the hydraulic oil after passing through the filtration system flows back into the hydraulic jack and controls the hydraulic oil in the hydraulic station to mix the hydraulic oil according to the ratio scheme, and then transmits the hydraulic oil according to the flow direction of the hydraulic oil.

[0108] When the actual viscosity inside the filter top matches the appropriate viscosity, it means that there are impurities in the hydraulic oil in the hydraulic jack before filtration, causing the viscosity to not meet the requirements. Then it can continue to be used after filtration, thus existing in the hydraulic jack.

[0109] Step 602: When the actual viscosity in the filter top matches the high viscosity, the hydraulic oil after passing through the filter system is controlled to be discharged into the high viscosity oil tank.

[0110] When the actual viscosity in the filter top matches the high viscosity, it means that the filtered hydraulic oil meets the requirements of high-viscosity hydraulic oil, so it can be discharged into the high-viscosity oil tank and used as high-viscosity hydraulic oil. It should be noted here that the oil will also be distinguished according to its usage time. If the usage time is short and there is no difference from new hydraulic oil, it will be discharged into the high-viscosity oil tank. If the usage time is not that short and there is a clear difference from new hydraulic oil, it will still be discharged into the waste area.

[0111] Step 603: When the actual viscosity in the filter top matches the low viscosity, the hydraulic oil after passing through the filter system is controlled to be discharged into the low viscosity oil tank.

[0112] When the actual viscosity in the filter top matches the low viscosity, it means that the filtered hydraulic oil meets the requirements of low viscosity hydraulic oil, so it can be discharged into the low viscosity oil tank and used as low viscosity hydraulic oil. The remaining requirements are the same as step 602 and will not be repeated here.

[0113] Step 604: When the actual viscosity in the filter top and the actual viscosity in the station, high viscosity, and low viscosity do not match, a calculation is performed based on the actual viscosity in the filter top and the actual viscosity in the station to obtain a viscosity deviation value.

[0114] The viscosity deviation is the deviation between the actual viscosity in the filter head and the actual viscosity in the station. The calculation method is to subtract the two.

[0115] Step 605: When the viscosity deviation value falls into a preset unreasonable deviation range, the hydraulic oil after passing through the filtering system is controlled to be directly discharged to a preset waste area.

[0116] The unreasonable deviation range is the range that completely deviates from the actual viscosity in the station and affects the oil quality in the circulating oil tank. When the viscosity deviation value falls into the unreasonable deviation range, it means that the internal hydraulic oil will seriously affect the oil quality, so it cannot be discharged into the circulating oil tank in the hydraulic station.

[0117] Step 606: When the viscosity deviation value does not fall into the unreasonable deviation range, the hydraulic oil after passing through the filtering system is controlled to be discharged into the circulating oil tank.

[0118] When the viscosity deviation value does not fall into the unreasonable deviation range, it means that the viscosity of the oil in the circulating oil tank is not greatly affected, and the oil can be discharged into the circulating oil tank.

[0119] Reference Figure 8 , when the viscosity deviation value falls into an unreasonable deviation range, the method of controlling the hydraulic oil after passing through the filtration system to be directly discharged to the waste area includes: Step 700: Determine the adjustment viscosity range based on the actual filter top viscosity, high viscosity and low viscosity.

[0120] The adjustable viscosity range is the adjustable range. Here, under normal circumstances, the actual viscosity inside the filter top is between high viscosity and low viscosity, so the range is generally between high viscosity and low viscosity, but it cannot reach the values ​​of high viscosity and low viscosity.

[0121] Step 701: When there is a partial overlap between the adjustment viscosity range and the preset reasonable deviation range, determine the overlapping range.

[0122] The reasonable deviation range is the range of reasonable deviation between the actual viscosity in the filter top and the actual viscosity in the station. The overlapping range is the range where both the adjustment viscosity range and the reasonable deviation range exist.

[0123] Step 702: Determine the trim oil amount corresponding to the high viscosity or low viscosity hydraulic oil based on the overlapping range, the actual filter top viscosity, the hydraulic oil amount, the high viscosity and the low viscosity, define the trim oil amount corresponding to the high viscosity hydraulic oil as the high viscosity trim oil amount, and define the trim oil amount corresponding to the low viscosity hydraulic oil as the low viscosity trim oil amount.

[0124] The trim oil quantity is the quantity of hydraulic oil corresponding to the actual viscosity in the filter top that can be mixed to reach the required high viscosity or low viscosity hydraulic oil in the overlap range. The calculation method is to determine whether the hydraulic oil corresponding to the trim oil quantity is high viscosity or low viscosity according to the small or large viscosity in the actual filter top in the overlap range, and then establish an equation based on the overlap range, the actual viscosity in the filter top, the hydraulic oil quantity, the high viscosity and the low viscosity to obtain the trim oil quantity. Here, the trim oil quantity is a range value.

[0125] Step 703: When the amount of high-viscosity trimming oil or low-viscosity trimming oil is greater than a preset reasonable critical oil amount value, the hydraulic oil after passing through the filtering system is controlled to be directly discharged to the waste area.

[0126] The reasonable critical oil volume value is that although adding a certain amount of hydraulic oil can definitely reach the overlapping range, it will also cause waste when the amount is too much, and the cost is higher than directly discharging the corresponding hydraulic oil, so the critical value is set. This value is set by the staff in this field based on their own experience. When it is greater than, it means that the amount of oil added for adjustment is too much, which is relatively wasteful, so the hydraulic oil after passing through the filtration system is controlled to be directly discharged to the waste area.

[0127] Step 704: When the amount of high-viscosity trim oil or low-viscosity trim oil is lower than a reasonable critical oil amount, the hydraulic oil after passing through the filtration system is controlled to be discharged into the circulating oil tank, and the high-viscosity oil tank or low-viscosity oil tank is discharged into the circulating oil tank according to the corresponding amount of high-viscosity trim oil or the corresponding amount of low-viscosity trim oil, and then the contents of the circulating oil tank are mixed evenly.

[0128] When the amount of high-viscosity trim oil or low-viscosity trim oil is lower than the reasonable critical oil amount value, it means that the deviation requirement of the hydraulic oil in the circulating oil tank can be met after mixing. In this case, the hydraulic oil after passing through the filtration system can be controlled to be discharged into the circulating oil tank, and the high-viscosity oil tank or low-viscosity oil tank can be discharged into the circulating oil tank according to the corresponding amount of high-viscosity trim oil or the corresponding amount of low-viscosity trim oil, so that the overall addition will not affect the quality of the oil in the circulating oil tank.
