Description

Technical Field

[0001] This invention belongs to the field of engineering construction technology, specifically a device and method for detecting the amount of material used in ultra-deep vibratory drilling. Background Technology

[0002] In vibro-compaction pile construction, it is necessary to continuously and quantitatively add stones into the formed hole. Currently, vibro-compaction devices mainly use two feeding methods: one is internal feeding through the internal channel of the drill rod, and the other is direct feeding at the hole opening. When direct feeding at the hole opening is used, the stones are poured at the hole opening, and the amount added usually relies on experience estimation or post-construction measurement, making it difficult to achieve real-time and accurate measurement during construction. This leads to inaccurate control of the filling amount, affecting the pile quality and material costs. When internal feeding is used, the stones are transported to the bottom of the hole through the hollow rod in the center of the vibro-compaction device. Although this method is advantageous for deep hole feeding, due to the closed transport path and severe environmental vibration, existing technologies lack a real-time material quantity detection device and method that can be integrated into this structure and adapt to complex working conditions. This makes it impossible to accurately grasp the actual filling progress and material quantity during construction, which not only affects construction efficiency but may also pose potential risks to the uniformity of pile quality. Therefore, a device and method that can be matched with the internal feeding method and achieve accurate feeding calculation is proposed. Summary of the Invention

[0003] To address the above problems, this invention provides a device and method for detecting the material quantity of ultra-deep vibratory drills, which solves the problem that it is inconvenient to detect and calculate the material quantity of vibratory drill rods used for internal hole cutting.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A material quantity detection device for ultra-deep vibratory drilling includes a counterweight for being placed on the material surface and moving with the material as it descends. A flexible connector is connected to the counterweight, and the upper end of the flexible connector is housed in a receiving component. The receiving component can roll up the flexible connector to control the descent height of the counterweight. A sensor for detecting the extension length of the flexible connector is connected to the receiving component. A first detector is connected to the receiving component. The first detector is used to detect the first tension value at the initial material surface position of the counterweight and the second tension value at the material surface position after discharge. The release length of the flexible connector is determined by the position of the first tension value and the position of the second tension value, so as to determine the descent height of the material surface.

[0005] As a further improvement to the above solution, the storage component is rotatably connected to the outer shell, and the outer shell is connected to a drive source that drives the storage component to reciprocate. The first detector is positioned between the storage component and the outer casing to measure the tensile force on the storage component.

[0006] As a further improvement to the above solution, the receiving component is a winding roller, and both ends of the receiving component are provided with outwardly protruding flanges, on which transmission teeth are provided; A pressure roller is movably mounted on the outer casing. The surface of the pressure roller contacts and presses against the flexible connector on the storage component. A gear with meshing transmission teeth is fixed on the rotating shaft of the pressure roller for stretching and combing the flexible connector when it is released.

[0007] As a further improvement to the above solution, the side of the outer shell is provided with an inclined groove, which is inclined toward the side of the flexible connector extending outward, and a slide seat is slidably provided on the inclined groove and is rotatably disposed relative to the rotating shaft of the pressure roller. A lever is rotatably mounted on the outer side of the housing. One end of the lever contacts the side of the slide. A torsion spring is also provided between the lever and the housing to push the slide to the inclined side of the chute so as to press the pressing roller against the flexible connector.

[0008] As a further improvement to the above solution, the pressure roller includes an inner ring and an outer ring, which rotate in one direction, and a protective layer is also provided on the outer ring.

[0009] As a further improvement to the above solution, the outer shell is fixedly mounted on the base on which the drill rods are fixed to each other. The base is provided with a guide tube to facilitate the passage of the flexible connector and to guide the up and down movement of the flexible connector. A horn tube is installed below the guide tube, and a second detector is installed between the guide tube and the horn tube to detect the tension when the counterweight presses against the horn tube, so as to limit the top position of the counterweight.

[0010] This application also provides a method for measuring the material consumption of ultra-deep vibratory drilling, characterized by comprising the following steps: Step S1: Hole Formation Construction: Start the vibratory compactor and drive the vibratory drill rod vertically down to the preset pile depth; Step S2: Material feeding construction preparation and initial parameter calibration. Position the self-weighing hopper and material quantity detection device, and debug and calibrate the first detector. Weigh the material to be fed through the self-weighing hopper, record the weighed weight M, and lift it into the feed port of the drill rod for feeding. Fill the inner rod feeding channel of the vibratory drill rod with stone, control the release of the flexible connector of the receiving part, and lower the counterweight to the surface of the stone. When the reading of the first detector of tension gradually decreases, record the tension reading at this time as F0, and set the length of the flexible connector (2) released at the height position of the counterweight (1) at this time as the initial material surface height H0. At the same time, record the cross-sectional area S of the inner rod feeding channel and the stone bulk density ρ parameters. Step S3: The material feeding and quantity of the inner rod are monitored in real time. The vibratory compactor continues to vibrate, and the stone inside the drill rod is filled into the pile hole. The drill rod is raised in sections at a preset speed so that the stone continuously fills the pile hole space formed by the raising of the drill rod. During this process, the counterweight descends synchronously with the material surface. The first detector collects the tension value Ft in real time and controls the release of the flexible connector to keep Ft less than F0 until Ft drops to 0 and the release stops. The length of the flexible connector released by the sensor when Ft drops to 0 is recorded, i.e., the height H1. Calculate the material level drop height ΔH1: ΔH1 = H0 - H1; Then, according to the formulas: V=S×ΔH and m=ρV, The discharge volume V1 = S × ΔH and the discharge mass m1 = ρV1 were calculated separately. Step S4: Testing the compaction of the pile body with stone: After the stone inside the drill rod fills the pile hole section corresponding to the current drill rod lifting height, control the drill rod to press down and vibrate to compact the filled stone. During the compaction process, the amount of stone consumed is the amount of stone when the drill rod slowly rises from the downward pressure position to the position when the drill rod starts to feed material in step S2. The measurement method is calculated according to the detection method in step S3. Ultimately, the amount of stone used in the pile hole corresponding to the drill rod lifting height is the sum of the stone material used during the feeding process and the stone material used during the compaction process; Step S5: Material replenishment and circulation. After completing the material feeding and compaction corresponding to one drill rod lifting height, control the storage component to retract the flexible connector and lift the counterweight to the highest position; fill the drill rod with stone material, and then repeat steps S2 to S4 to perform the next material feeding and detection cycle until the entire pile hole is filled; accumulate the amount of stone material calculated in each cycle to obtain the total material consumption of the entire pile.

[0011] As a further improvement to the above scheme, in step S2, debugging and calibrating the first detector includes the following steps: First, when the counterweight is completely lifted and detached from the material surface and the flexible connector is in a vertically tensioned state, the reading of the first detector is set to zero. Subsequently, the control unit slowly releases the flexible connector, causing the counterweight to descend at a constant low speed, and continuously records the changes in the reading of the first detector; when the reading first shows an inflection point from continuous increase to decrease, it is confirmed that the counterweight is just in contact with the material surface, and the reading corresponding to this inflection point is determined as F0.

[0012] As a further improvement to the above scheme, in step 5, since the vibratory impactor continuously vibrates during the process of the counterweight being raised to the highest position and during the material unloading, the drill rod is continuously unloaded. Therefore, the actual unloading height within the height range of the drill rod being raised should be: ΔH5 = Δ1H + ΔH2, ΔH2 is the height difference of the material surface drop during the process from the completion of the first feeding to the start of the second feeding; Therefore, the actual volume of material discharged into the pile hole should be: V2 = S × ΔH5, Actual material feed mass: m2=ρV2.

[0013] As a further improvement to the above scheme, in step 5, the zero point of the counterweight is checked using the guide tube and horn tube structure: Before each construction cycle begins, when the counterweight is retracted to its highest position and contacts the horn tube, the tension value of the second detector at this time is read and compared with the pre-stored benchmark value. If there is a deviation and it continues to exceed the limit, it is determined that there is foreign matter deposit in the guide mechanism or the counterweight shape is abnormal, and it needs to be cleaned or inspected.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, by employing a counterweight, a flexible connector, a storage component, and utilizing sensors and a first detector, the position of the counterweight (i.e., material surface position detection) and the release length of the flexible connector (i.e., material surface descent height detection) are achieved. This allows for more accurate calculations during subsequent stone material statistics. Furthermore, it makes operation more convenient for material feeding methods such as internal hole feeding, which are not easily observed directly. Moreover, it allows for complete data-driven statistics, making management easier. In this invention, the pressure roller can press the flexible connector on the receiving component, keeping the flexible connector fully stretched on the receiving component. When the flexible connector is released, it prevents the flexible connector on the receiving component from being sent off, and maintains the accurate consistency between the length of the flexible connector being transported and the length detected by the sensor. In this invention, the amount of stone material fed into the pile hole is calculated, as is the consumption of stone material during the compaction process. This allows for accurate control of the amount of material fed into each section while ensuring that the pile foundation meets the requirements. The material calculation is more precise and convenient. This invention enables real-time, continuous, and precise measurement of the material feed rate into the inner hole of the vibratory drilling rod. By dynamically tracking changes in material level height and automatically calculating the data, it completely changes the traditional experience-based estimation method, allowing for precise control of the filler quantity during construction. The device structure design fully considers the strong vibration, deep hole, and stone flow characteristics of vibratory drilling. Through methods such as counterweight follow-up, flexible connection, tensile inflection point judgment, and stability point sampling, interference is effectively filtered out, ensuring the reliability and accuracy of measurements under complex working conditions. Through standardized segmented feeding detection and cyclic process, the feeding, compaction, and replenishment processes are quantified, significantly improving the controllability of the construction process and the uniformity of pile quality, while also achieving precise material delivery and cost savings.

[0017] To enable those skilled in the art to better understand the technical solution, the present invention will be described in detail below with reference to embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0018] like Figure 1-5 As shown, the specific solution of this embodiment is as follows: a material quantity detection device for ultra-deep vibratory drilling includes a counterweight 1, which is placed on the material surface and moves with the material as it descends. A flexible connector 2 is connected to the counterweight 1. Specifically, the flexible connector 2 can be a steel wire rope or an iron chain. In this embodiment, a steel wire rope is used. The upper end of the flexible connector 2 is stored in a storage component 3, which is a winding roller. The storage component 3 can store and roll up the flexible connector 2 to control the descent height of the counterweight 1. A sensor 32 for detecting the extension length of the flexible connector 2 is connected to the storage component 3. The sensor 32 is a rope displacement sensor. The sensor 32 is connected to a data collector. After collecting the data, the data collector transmits it to the relevant equipment in the control room for subsequent data analysis and processing calculations. Specifically, it is used to detect the extension length of the flexible connector 2. This is existing technology, and the specific structure will not be described here. The first detector 4 is connected to the receiving component 3. The first detector 4 is used to detect the first tension value at the initial material surface position of the counterweight 1 and the second tension value at the material surface position after discharge. The length released by the flexible connector 2 is judged by the position of the first tension value and the position of the second tension value to determine the descent height of the material surface. By determining the discharge height of the material surface during the discharge process, the amount of stone used in the drill rod is calculated, which is the amount of stone to be detected.

[0019] As a preferred embodiment of the above, the storage component 3 is rotatably connected to the outer shell 5, and the outer shell 5 is connected to a drive source for driving the storage component 3 to reciprocate. Specifically, the drive source is a drive motor, which is connected to a reducer and is mutually driven with the storage component 3 to drive the storage component 3 to rotate, thereby realizing the retraction and expansion of the flexible connector 2. The first detector 4 is disposed between the storage component 3 and the outer shell 5 and is used to measure the tensile force on the storage component 3. Specifically, the first detector 4 is a pressure sensor. In this embodiment, the first detector 4 is connected to the data collector. The data collector collects the pressure changes detected by the first detector 4 in real time. The pressure sensor detects the pressure on the storage component 3 and converts it into the tensile force of the storage component 3 on the counterweight 1. When the counterweight 1 is on the material surface or not on the material surface, the pressure detected by the first detector 4 will change, and the change in the position of the counterweight 1 can be determined based on the pressure change of the first detector 4.

[0020] like Figure 2 , 3 As shown in Figure 4, the two ends of the receiving component 3 are provided with outwardly protruding flanges 31, and the flanges 31 are provided with transmission teeth; a pressure roller 6 is movably provided on the outer shell 5, and the surface of the pressure roller 6 contacts and presses against the flexible connector 2 on the receiving component 3. Through the provided pressure roller 6, the flexible connector 2 can be pressed tightly onto the receiving component 3 to prevent loosening, especially when the flexible connector 2 is released, to prevent the flexible connector 2 from loosening, and to avoid the problem of the displacement detected by the sensor 32 and the release length of the flexible connector 2 being inconsistent during the release process. A gear that meshes with the transmission teeth is fixedly provided on the rotating shaft of the pressure roller 6 for stretching and combing the flexible connector 2 during release. Figure 3 As shown, the pressure roller 6 can also rotate synchronously by the drive of the storage component 3. And through the transmission between the two gears, the linear speeds of the storage component 3 and the pressure roller 6 are different. When the flexible connector 2 is released, the pressure roller 6 rotates quickly to comb the flexible connector 2 outward, keeping the flexible connector 2 from being completely straightened.

[0021] As a preferred embodiment of the above, the outer shell 5 is provided with a sloping groove 8 on its side, the sloping groove 8 being inclined toward the side extending from the flexible connector 2, and a slide seat 7 being slidably disposed on the sloping groove 8 and rotatably disposed relative to the rotating shaft of the pressing roller 6; a lever 9 is also rotatably disposed on the outer side of the outer shell 5, one end of the lever 9 being in contact with the side of the slide seat 7, and a torsion spring is also provided between the lever 9 and the outer shell 5, for pushing the slide seat 7 to move toward the inclined side of the sloping groove 8, so as to press the pressing roller 6 against the flexible connector 2. Under the pull of the torsion spring, a thrust can be generated on the lever 9, and the thrust of the lever 9 acts on the slide seat 7, so that the pressing roller 6 can be further pressed between itself and the flexible connector 2, maintaining the effect during the combing process.

[0022] As a preferred embodiment of the above, the pressure roller 6 includes an inner ring and an outer ring, which can rotate unidirectionally. Specifically, the inner ring and the outer ring are driven by a ratchet mechanism. The inner and outer rings of the pressure roller 6 can rotate relative to each other only when the flexible connector 2 is being retracted. A protective layer is also provided on the outer ring, which can increase the friction between the outer ring and the flexible connector 2 to achieve a better combing effect.

[0023] like Figure 1 As shown, in a preferred embodiment, the outer shell 5 is fixedly mounted on the base 10 on which the drill rods are fixed. The base 10 is provided with a guide tube 11 for the flexible connector 2 to pass through, which guides the up and down movement of the flexible connector 2 and ensures that the flexible connector 2 lifts the counterweight 1 vertically. A horn tube 12 is provided below the guide tube 11, and a second detector 13 is provided between the guide tube 11 and the horn tube 12 to detect the pressure when the counterweight 1 presses against the horn tube 12, so as to limit the top position of the counterweight 1. Specifically, the second detector 13 is also provided with a pressure sensor, which is also connected to the data collector signal connected to the first detector 4. It can detect whether the counterweight 1 has moved to the highest limit position. In addition, the pressure value of the second detector 13 can be compared with the reference value to detect whether there is a blockage in the guide tube 11 or whether there are foreign objects stuck or damaged on the counterweight 1.

[0024] A method for detecting material feeding using a device for detecting the material quantity of an ultra-deep vibratory drilling machine includes the following steps: Step S1: Hole Formation Construction: Start the vibratory compactor and drive the vibratory drill rod vertically down to the preset pile depth; the high-frequency vibration generated by the vibratory compactor enables the drill rod to effectively penetrate the soil layer and form a pile hole of the predetermined depth, laying the foundation for subsequent stone filling.

[0025] Step S2: Material preparation and initial parameter calibration. Position the self-weighing hopper and the aforementioned material quantity detection device, and debug and calibrate the first detector 4. During debugging and calibration, first, when the counterweight 1 is completely lifted by the housing 3 and detached from the material surface, and the flexible connector 2 is in a vertically tensioned state, reset the reading of the first detector 4 to zero. Weigh the material to be discharged through the self-weighing hopper, record the weighed weight M, and then lift it into the feed inlet of the drill rod for discharge. Subsequently, stones are loaded into the inner rod feeding channel of the vibratory drill rod. After all the stones in the self-weighing hopper are put into the drill rod, the receiving component 3 is controlled to slowly release the flexible connector 2, so that the counterweight 1 descends at a constant low speed, and the reading changes of the first detector 4 are continuously recorded. When the reading first shows an inflection point from continuous increase to decrease, it is confirmed that the counterweight 1 just contacts the material surface, and the reading corresponding to the inflection point is determined as F0. The length of the flexible connector 2 released at the height position of the counterweight 1 at this time is the initial material surface height H0. At the same time, the cross-sectional area S of the inner rod feeding channel and the stone bulk density ρ parameters are recorded. Step S3: The material feeding and quantity of the inner rod are monitored in real time. The vibratory compactor continues to vibrate, and the stone inside the drill rod is filled into the pile hole. The drill rod is raised in sections at a preset speed so that the stone continuously fills the pile hole space formed by the raising of the drill rod. During this process, the counterweight 1 descends synchronously with the material surface. The first detector 4 collects the tension value Ft in real time and controls the release of the flexible connector 2 to keep Ft less than F0 until Ft drops to 0 and the release stops. The length of the flexible connector 2 released, i.e., the height H1, is recorded by the sensor 32 when Ft drops to 0. Calculate the material level drop height ΔH1: ΔH1 = H0 - H1; Then, according to the formulas: V=S×ΔH and m=ρV, The discharge volume V1 = S × ΔH and the discharge mass m1 = ρV1 were calculated separately. This segmented real-time monitoring method allows for precise control over stone consumption at each stage of construction.

[0026] Step S4: Testing the compaction of the pile body with stone: After the stone inside the drill rod fills the pile hole section corresponding to the current drill rod lifting height, control the drill rod to press down and vibrate to compact the filled stone. During the compaction process, the amount of stone consumed is the amount of stone when the drill rod slowly rises from the downward pressure position to the position when the drill rod starts to feed material in step S2. The measurement method is calculated according to the detection method in step S3. Ultimately, the amount of stone used in the pile hole corresponding to the drill rod lifting height is the sum of the stone used during the feeding process and the stone used during the compaction process; thus, while ensuring the required compaction of the pile body, it also accurately records the additional stone consumption during the compaction process. Step S5: Material replenishment and circulation. After completing the material feeding and compaction corresponding to one drill rod lifting height, control the storage component 3 to retract the flexible connector 2 and lift the counterweight 1 to the highest position. In this embodiment, the zero point verification of the counterweight 1 is carried out using the structure of the guide tube 11 and the horn tube 12: that is, before the start of each construction cycle, when the counterweight 1 is retracted to the highest position, it contacts the horn tube 12. By reading the pressure value of the second detector 13 at this time and comparing it with the pre-stored benchmark value, if there is a deviation and it continues to exceed the limit, it is determined that there is foreign matter deposition in the guide mechanism or the shape of the counterweight 1 is abnormal, and it needs to be cleaned or inspected.

[0027] After counterweight 1 is raised to its highest position, fill the drill rod with stone. It should be noted that because the vibratory compactor vibrates continuously during the process of raising counterweight 1 to its highest position and during the feeding process, the drill rod is continuously being fed. Therefore, the actual feeding height within the height the drill rod is raised should be: ΔH5 = ΔH1 + ΔH2, ΔH2 is the height difference of the material surface drop during the process from the completion of the first feeding to the start of the second feeding; Therefore, the actual volume of material discharged into the pile hole should be: V2 = S × ΔH5, Actual material feed mass: m2=ρV2.

[0028] Please refer to the appendix. Figure 5 As shown, During the first feeding process inside the drill pipe, the calculated amount of stone used is: V=S×ΔH1, m1=ρV1; During the second feeding process inside the drill pipe, there is a loss of height ΔH2, because the material level continuously decreases until it reaches position H3. Figure 5 In (b), H0' represents the initial material level height detected by counterweight 1 during the second feeding process: Specifically, in the calculation process, the mass of the material to be fed, M, is first weighed using a self-weighing hopper to calculate the required material level difference ΔH3 within the drill rod. Based on the last detected material level position during the first feeding, after feeding a mass of stone M, the height within the drill rod should be H4. However, the initial material level position detected after the second feeding was actually H0'. The material loss is ΔH2 = ΔH3 - (H0' - H1), which means ΔH2 = ΔH3 - ΔH4. ΔH4 represents the difference between the material level height detected when counterweight 1 is lifted during the first feeding process and the initial material level height detected by the counterweight during the second feeding process. Therefore, the actual amount of material fed into the drill pipe can be calculated.

[0029] Then repeat steps S2 to S4 to perform the next material feeding and inspection cycle until the entire pile hole is filled; accumulate the amount of stone calculated in each cycle to obtain the total amount of material used for the entire pile.

[0030] In addition, the mass of the stone weighed in the hopper can be calculated and compared with the mass of the stone calculated by measuring the material surface to accurately monitor the material usage. When the weight is less than or more than 20% of the hopper's weighing capacity, it is determined that the detection process of the measuring device has an abnormality. The abnormal data is fed back to the control room for troubleshooting. When the deviation is within 20%, it is considered normal and the equipment continues to operate.

Step S3: The inner rod is fed and the material quantity is detected in real time. The vibratory compactor is kept vibrating continuously. The stone material in the drill rod is filled into the pile hole. The drill rod is raised in sections at a preset speed so that the stone material continues to fill the pile hole space formed by the raising of the drill rod. During this process, the counterweight (1) drops synchronously with the material surface. The first detector (4) collects the tensile force value Ft in real time and controls the release of the flexible connector (2) to keep Ft less than F0 until Ft drops to 0 and the release stops. The length of the release of the flexible connector (2) detected by the sensor (32) when Ft drops to 0 is recorded, i.e., the height H1. Calculate the material level drop height ΔH1: ΔH1 = H0 - H1; Then, according to the formulas: V=S×ΔH and m=ρV, The discharge volume V1 = S × ΔH and the discharge mass m1 = ρV1 were calculated separately. Step S4: Testing the compaction of the pile body with stone: After the stone inside the drill rod fills the pile hole section corresponding to the current drill rod lifting height, control the drill rod to press down and vibrate to compact the filled stone. During the compaction process, the amount of stone consumed is the amount of stone when the drill rod rises from the downward pressure position to the position when the drill rod starts to feed material in step S2. The measurement method is calculated according to the detection method in step S3. Ultimately, the amount of stone used in the pile hole corresponding to the drill rod lifting height is the sum of the stone material used during the feeding process and the stone material used during the compaction process; Step S5: Material replenishment and circulation. After completing the material feeding and compaction corresponding to the height of the drill rod lifting, control the storage component (3) to rewind the flexible connector (2) and lift the counterweight (1) to the highest position; fill the drill rod with stone material, and then repeat steps S2 to S4 to perform the next material feeding detection cycle until the entire pile hole is filled; accumulate the amount of stone material calculated in each cycle to obtain the total amount of material used for the entire pile.

A method for detecting material feeding using a material quantity detection device for ultra-deep vibratory drilling according to claim 7, characterized in that, In step S2, debugging and calibrating the first detector (4) includes the following steps: First, when the counterweight (1) is completely lifted and detached from the material surface by the storage part (3) and the flexible connector (2) is in a vertically tensioned state, the reading of the first detector (4) is set to zero; Subsequently, the control receiver (3) releases the flexible connector (2), causing the counterweight (1) to descend at a constant low speed, and continuously records the reading changes of the first detector (4); when the reading first shows an inflection point from continuous increase to decrease, it is confirmed that the counterweight (1) just contacts the material surface, and the reading corresponding to the inflection point is determined as F0.

9. A method for detecting material feeding using a material quantity detection device for ultra-deep vibratory drilling according to claim 7, characterized in that, In step 5, since the vibratory impactor continues to vibrate during the process of lifting the counterweight to the highest position and feeding material, the drill rod is continuously feeding material. Therefore, the actual feeding height within a certain height of the drill rod lifting should be ΔH5=ΔH1+ΔH2, where ΔH2 is the difference in the material surface drop height between the completion of the first feeding and the start of the second feeding. Therefore, the actual volume of material discharged into the pile hole should be: V2 = S × ΔH5, Actual material feed mass: m2=ρV2.

A method for detecting material feeding using a material quantity detection device for ultra-deep vibratory drilling according to claim 7, characterized in that, In step 5, the zero point of the counterweight (1) is checked using the structure of the guide tube (11) and the horn tube (12): That is, before each construction cycle begins, when the counterweight (1) is pulled to the highest position, it contacts the horn tube (12); by reading the tension value of the second detector (13) at this time and comparing it with the pre-stored benchmark value, if there is a deviation and it continues to exceed the limit, it is determined that there is foreign matter deposit in the guide mechanism or the counterweight (1) has an abnormal shape, and it needs to be cleaned or inspected.
