Description

Technical Field

[0001] This application relates to the technical field of leveling devices, and in particular to a large-area multi-unit base leveling device. Background Technology

[0002] Three-ring assembly of tunnel segments refers to assembling three tunnel segments into a single unit to verify the dimensions and precision of the tunnel segment mold. For tunnel segments with a diameter greater than 6 meters, three-ring splicing is performed every 2-3 segments along the diameter direction. In special cases, such as in subway sections, three-ring splicing is performed every two rings. Reinforced concrete tunnel segments for subways are made using high-precision steel molds. Due to insufficient dimensional accuracy of the steel molds themselves or deformation caused by vibrations during production and use, GB50299-1999 "Code for Construction and Acceptance of Underground Railway Engineering" stipulates that a set of three-ring horizontal assembly inspections should be performed every 200 rings produced for each mold set to ensure that the precision of the tunnel segments and molds meets the standards specified in the code. In the actual three-ring assembly inspection process, even slight differences in ground flatness can have a significant adverse impact on the final assembly effect. Therefore, three-ring tunnel segment assembly inspection requires a device that can ensure the horizontal assembly of the tunnel segments to avoid the adverse effects of ground elevation differences on the assembly effect.

[0003] Currently, the assembly platform used for the three-ring segment assembly includes an assembly platform base, an adjustment plate, and an inspection platform. The tunnel segments are set on the adjustment plate. The inspection platform includes columns and crossbeams; adjacent columns are connected by crossbeams. The adjustment plate includes an upper adjustment plate and a lower adjustment plate, connected by an adjustment device. Both the inspection platform and the adjustment plate are installed on the assembly platform base. The height of the tunnel segment is adjusted using the adjustment device on the adjustment plate, ensuring a consistent horizontal height. This effectively adjusts the height of the tunnel segment and avoids the problem of large inspection errors caused by uneven settlement of the assembly platform foundation.

[0004] During the process of leveling the assembly platform, two methods are commonly used to detect its levelness: the first is using a level, and the second is using a horizontal string to mark points. The laser line emitted by the level and the marked points provide horizontal positioning points for the assembly platform, but manual adjustment is required to align the platform with these points. Due to different viewing angles (such as looking down or up), the platform may appear level to the viewer, but there is still some error in the actual alignment. This method results in low precision in leveling the assembly platform. Furthermore, as the inner diameter of existing tunnel segments increases, the precision requirements for leveling the assembly platform also rise. The two methods mentioned above are insufficient to meet the precision requirements for three-ring assembly of large-diameter tunnel segments. Summary of the Invention

[0005] This application provides a large-area multi-unit base leveling device, the purpose of which is to improve the accuracy of base adjustment level.

[0006] In a first aspect, this application provides a large-area multi-unit base leveling device, which adopts the following technical solution: A large-area multi-unit base leveling device includes a base, on which horizontal plates are spaced apart, and between the base and the horizontal plates are a plurality of adjustment mechanisms, which are used to drive the horizontal plates to move toward or away from the base; a detection mechanism is also provided on the horizontal plates, which includes a plurality of liquid level tubes, the axial direction of which is arranged along the spacing direction between the base and the horizontal plates, the plurality of liquid level tubes are all connected to the horizontal plates, the upper ends of the plurality of liquid level tubes are interconnected, the lower ends of the plurality of liquid level tubes are interconnected, and the outer wall of the liquid level tube is provided with a scale indicating the liquid level along its own axial direction.

[0007] By adopting the above technical solution, the base is used to support the entire leveling device, while the leveling plate supports the segments or the platform under the segments during the assembly of the three-ring segments. The adjustment mechanism is used to support the leveling plate and simultaneously raise and lower it. Several adjustment mechanisms can be independently controlled to adjust the different raising and lowering heights of each position of the leveling plate, thus adjusting the levelness of the leveling plate.

[0008] The detection mechanism consists of several liquid level tubes, interconnected at both ends, forming a communicating vessel. Following the principle of communicating vessels, the liquid levels in all the tubes are at the same horizontal level. Therefore, when the level plate is horizontal, the liquid levels in all the tubes are at the same height. When the level plate is not horizontal, the liquid level readings in the tubes on the higher side of the level plate are lower, and vice versa, because the tubes have scales for reading the liquid level. Based on this principle, the detection mechanism can reflect the horizontal state of the level plate in real time.

[0009] The system, consisting of several detection mechanisms and several adjustment mechanisms, can adjust the level plate to a horizontal state and read the specific value of the liquid level in the level tube to reflect the levelness of the level plate. Because a specific value reflects the levelness of the level plate, the accuracy of the level plate adjustment can be improved.

[0010] Optionally, the detection mechanism further includes a liquid storage tank, with the upper end of the liquid level tube connected to the upper end of the liquid storage tank and the lower end of the liquid level tube connected to the lower end of the liquid storage tank.

[0011] By adopting the above technical solution, the liquid level tank can store liquid and facilitate the interconnection between liquid level pipes.

[0012] Optionally, the detection mechanism further includes a mounting frame, on which a plurality of the liquid level tubes are mounted;

[0013] A plurality of parallel connecting components are provided between the mounting bracket and the horizontal plate. The parallel connecting components include connecting bolts and pressure gauges. The mounting bracket has a first connecting hole, and the horizontal plate has a second connecting hole. The first connecting hole and the second connecting hole are interconnected. The connecting bolt passes through the first connecting hole, and one end of the connecting bolt is inserted into the second connecting hole. The connecting bolt is connected to the inner wall of the second connecting hole by threads.

[0014] The pressure gauge is located between the mounting bracket and the horizontal plate. Both ends of the pressure gauge abut against the horizontal plate and the mounting bracket, respectively. The detection end of the pressure gauge abuts against the horizontal plate or the mounting bracket.

[0015] By adopting the above technical solution, the mounting bracket is used to install the liquid level tube.

[0016] The parallel connection components between the mounting bracket and the horizontal plate are designed to enable the mounting bracket to be installed through the cooperation of the first connecting hole, the second connecting hole, and the connecting bolt.

[0017] The pressure gauge installed between the mounting bracket and the horizontal plate can detect the distance between the mounting bracket and the horizontal plate, thereby improving the parallelism between the mounting bracket and the horizontal plate, ensuring that the mounting bracket and the horizontal plate are parallel to each other, and thus improving the detection accuracy of the detection mechanism.

[0018] Optionally, the pressure gauge is coaxially arranged with the connecting bolt and the pressure gauge is sleeved on the outside of the connecting bolt.

[0019] By adopting the above technical solution, the pressure gauge is sleeved on the connecting bolt. When the connecting bolt is tightened, the pressure gauge can provide real-time feedback on the pressure between the mounting bracket and the horizontal plate.

[0020] Optionally, the pressure gauge includes an installation sleeve and an indicating sleeve, wherein the installation sleeve and the indicating sleeve are coaxially arranged, the installation sleeve is sleeved on the outside of the indicating sleeve, and the indicating sleeve is slidably connected to the inner wall of the installation sleeve along its own axial direction.

[0021] The mounting sleeve is provided with a first sealing plate at the end away from the indicator sleeve, and the first sealing plate is connected to the mounting sleeve. The indicator sleeve is provided with a second sealing plate at the end away from the first sealing plate, and the second sealing plate is connected to the indicator sleeve.

[0022] A compression spring is provided between the first sealing plate and the second sealing plate, and the two ends of the compression spring are respectively connected to the first sealing plate and the second sealing plate.

[0023] An indicator window is provided through the side wall of the mounting sleeve, and several pressure indication scales are provided at intervals along the axial direction of the mounting sleeve on the side wall of the indicator window.

[0024] By adopting the above technical solution, the indicating sleeve and the mounting sleeve are slidably connected, so the compression spring ensures that the second sealing plate on the indicating sleeve and the first sealing plate on the mounting sleeve can respectively abut against the mounting bracket and the horizontal plate. The position of the indicating sleeve within the mounting sleeve can be viewed through the scale on the indicating window. Therefore, when the connecting bolts are tightened, the scale on the indicating window indicates the distance between the mounting bracket and the horizontal plate. Thus, when the leveling device is not powered, the pressure gauge can reflect the distance between the mounting bracket and the horizontal plate, ensuring that the mounting bracket and the horizontal plate are parallel.

[0025] Optionally, the adjustment mechanism includes a lead screw and a mounting box. One side of the mounting box is connected to the base, and the other side of the mounting box is connected to a threaded sleeve. The lead screw is inserted into the threaded sleeve and is threadedly connected to the inner wall of the threaded sleeve. The end of the lead screw away from the mounting box is connected to the horizontal plate. An adjustment drive assembly capable of driving the lead screw to rotate is provided inside the mounting box.

[0026] By adopting the above technical solution, the screw and the threaded sleeve are matched so that when the adjustment drive assembly drives the screw to rotate, the screw can move along the axial direction of the threaded sleeve, thus enabling the horizontal plate to be raised and lowered in the vertical direction.

[0027] Optionally, a insertion slot is provided at one end of the lead screw away from the horizontal plate, and the insertion slot is provided along the axial direction of the lead screw;

[0028] The adjustment drive assembly includes a connecting shaft, which is coaxially arranged with the lead screw and has a plug-in post at one end facing the lead screw. The plug-in post is inserted into the plug-in slot along the axial direction of the lead screw, and the plug-in post and the inner wall of the plug-in slot are slidably connected along the axial direction of the lead screw.

[0029] The end of the connecting shaft away from the lead screw is coaxially connected to a drive source capable of rotating the connecting shaft;

[0030] When the connecting shaft rotates, the side wall of the plug-in post abuts against the inner side wall of the plug-in groove.

[0031] By adopting the above technical solution, the connection between the plug-in pin on the connecting column and the plug-in slot on the lead screw is such that, when the connecting column rotates, the side wall of the plug-in pin abuts against the inner wall of the plug-in slot, allowing the connecting column to drive the lead screw to rotate synchronously. Meanwhile, the plug-in pin slides along its own axial direction against the inner wall of the plug-in slot, so when the connecting column drives the lead screw to rotate, the lead screw moves along its own axial direction within the threaded sleeve. Therefore, under the drive of the drive source, the connecting column can achieve the raising and lowering of the lead screw.

[0032] Secondly, another large-area multi-unit base leveling device provided in this application adopts the following technical solution: A large-area multi-unit base leveling device includes a base, with horizontal plates spaced apart on the upper side of the base, and a plurality of adjustment mechanisms arranged between the base and the horizontal plates. The adjustment mechanisms are used to drive the horizontal plates to move toward or away from the base. A detection mechanism is also provided on the horizontal plate, and the detection mechanism includes a plurality of liquid level tubes. The axial direction of the liquid level tubes is arranged along the spacing direction between the base and the horizontal plates. The plurality of liquid level tubes are all connected to the horizontal plates. The upper ends of the plurality of liquid level tubes are interconnected, and the lower ends of the plurality of liquid level tubes are interconnected. A liquid level sensor is provided on the liquid level tube.

[0033] By adopting the above technical solution, the base, level plate, and adjustment mechanism have the same structure and function as the aforementioned base leveling device. A liquid level tube is installed in the detection mechanism to detect the level of the level plate, and a liquid level sensor on the liquid level tube can automatically detect the liquid level inside the tube. Compared to manual reading of the liquid level, the liquid level sensor can read the liquid level more accurately, thus improving the leveling accuracy of the level plate.

[0034] Optionally, the adjustment mechanism further includes a plurality of hydraulic cylinders, which are arranged along the interval between the horizontal plate and the base. The plurality of hydraulic cylinders are disposed between the base and the horizontal plate, and both ends of the hydraulic cylinders are respectively connected to the base and the horizontal plate.

[0035] By adopting the above technical solution, the liquid level cylinder can automatically adjust the level plate according to the reading results of the liquid level sensor, so that the level plate can automatically adjust the level.

[0036] Optionally, a precision compensation component is provided between the hydraulic cylinder and the horizontal plate. The precision compensation component includes a mounting base and a compensation screw. The compensation screw is axially arranged along the axis of the hydraulic cylinder and its two ends are rotatably connected to the mounting base. The end of the hydraulic cylinder away from the base is connected to the mounting base.

[0037] A connecting platform is threaded onto the compensating screw, and the connecting platform is connected to the horizontal plate. A drive motor is coaxially connected to one end of the compensating screw.

[0038] By adopting the above technical solution, a precision compensation component is set between the hydraulic cylinder and the horizontal plate. The precision compensation component, through the setting of the compensation screw, mounting base, connecting platform and drive motor, can achieve higher precision adjustment of the horizontal plate. Therefore, it can compensate for the positioning accuracy of the hydraulic cylinder on the horizontal plate and improve the horizontal adjustment accuracy of the horizontal plate.

[0039] In summary, this application includes at least one of the following beneficial technical effects:

[0040] 1. The coordinated arrangement of several level tubes allows for real-time monitoring of the level plate's horizontal status through specific numerical values. After the level plate is adjusted, its levelness can also be determined using these values, ensuring that the levelness meets the requirements.

[0041] 2. The pressure gauge in the parallel connection assembly can detect the distance between the mounting bracket and the horizontal plate, thus improving the parallelism between the mounting bracket and the horizontal plate, and therefore improving the detection accuracy of the liquid level tube.

[0042] 3. A liquid level sensor installed on the liquid level tube can automatically detect the liquid level inside the tube, and together with the liquid level cylinder, it can automatically adjust the level plate to be horizontal. Attached Figure Description

[0057] The following is in conjunction with the appendix Figure 1 -Appendix Figure 11 This application will be described in further detail below.

[0058] Example 1:

[0059] A large-area multi-unit base leveling device, referring to Figure 1 The system includes a base 1, with horizontal plates 2 spaced apart vertically on the upper side of the base 1. An adjustment mechanism 3 is provided between the horizontal plates 2 and the base 1, with both sides of the adjustment mechanism 3 vertically connected to the horizontal plates 2 and the base 1 respectively. A detection mechanism 4 is also provided on the horizontal plates 2. First, the detection mechanism 4 detects the levelness of the horizontal plates 2, and then the adjustment mechanism 3 raises and lowers the horizontal plates 2 at various positions to ensure that the horizontal plates 2 are in a horizontal state.

[0060] Reference Figure 1 and Figure 2The detection mechanism 4 includes a mounting frame 43, which is located below the horizontal plate 2. Several liquid level tubes 41 are fixed on the mounting frame 43. The liquid level tubes 41 are axially arranged in the vertical direction, and several graduations are spaced along the axial direction on the outer wall of each liquid level tube 41. The graduations on the liquid level tubes 41 facilitate reading the liquid level height within the tubes.

[0061] A liquid storage tank 42 is also provided on the lower side of the mounting bracket 43. The upper ends of several liquid level tubes 41 are all connected to the upper end of the liquid storage tank 42, and the lower ends of several liquid level tubes 41 are all connected to the lower end of the liquid storage tank 42. Thus, a communicating vessel is formed between the liquid storage tank 42 and the several liquid level tubes 41. Therefore, following the principle of communicating vessels, the liquid level in the liquid storage tank 42 is at the same height as the liquid level in the several liquid level tubes 41. Therefore, when the level plate 2 is in a horizontal state, the liquid level in the several liquid level tubes 41 is at the same height. When the level plate 2 is not in a horizontal state, the liquid level reading in the liquid level tube 41 on the higher side of the level plate 2 is lower, and conversely, the liquid level reading in the liquid level tube 41 on the lower side of the level plate 2 is higher. Based on this principle, the detection mechanism 4 can reflect the horizontal state of the level plate 2 in real time.

[0062] Reference Figure 2 The mounting bracket 43 has several liquid level tubes 41 at different positions on the lower side of the horizontal plate 2. In this application, the number of liquid level tubes 41 is not less than three, and the three liquid level tubes 41 cannot be on the same straight line.

[0063] Reference Figure 3 and Figure 4 A plurality of parallel connecting components 44 are provided between the mounting bracket 43 and the horizontal plate 2. Each parallel connecting component 44 includes a connecting bolt 441. A plurality of first connecting holes 443 are formed through the mounting bracket 43 along its thickness direction on its lower side. A plurality of second connecting holes 444 are formed on the lower side of the horizontal plate 2. The first connecting holes 443 and the second connecting holes 444 are arranged in a one-to-one correspondence and are vertically interconnected. The connecting bolts 441 pass through the first connecting holes 443 and are inserted into the second connecting holes 444. The inner wall of the second connecting hole 444 is threadedly connected to the connecting bolts 441. Therefore, the connecting bolts 441 enable the mounting bracket 43 to be installed on the lower side of the horizontal plate 2.

[0064] Reference Figure 3 and Figure 4The parallel connection assembly 44 also includes a pressure gauge 442. The pressure gauge 442 is a pressure sensor and is sleeved on the outside of the connecting bolt 441. The two ends of the pressure gauge 442 along the axial direction of the connecting bolt 441 respectively abut against the horizontal plate 2 and the mounting bracket 43. The detection end of the pressure gauge 442 abuts against either the horizontal plate 2 or the mounting bracket 43. Therefore, by setting the pressure gauge 442, the distance between the horizontal plate 2 and the mounting bracket 43 can be detected, thereby ensuring that the mounting bracket 43 and the horizontal plate 2 are parallel to each other, thus improving the detection accuracy of the detection mechanism 4 in detecting the levelness of the horizontal plate 2.

[0065] Reference Figure 1 and Figure 2 There are several adjustment mechanisms 3, and each adjustment mechanism 3 is set in a one-to-one correspondence with the liquid level pipe 41. In the horizontal direction, the connection between the adjustment mechanism 3 and the liquid storage tank 42 passes through the corresponding liquid level pipe 41, so that the adjustment mechanism 3 can adjust the level of the level plate 2 in a timely manner according to the detection result of the corresponding liquid level pipe 41.

[0066] Reference Figure 1 and Figure 5 The adjusting mechanism 3 includes a lead screw 31, which is vertically oriented and its upper end is rotatably connected to the horizontal plate 2. A mounting box 32 is provided between the lower end of the lead screw 31 and the base 1. A threaded sleeve 33 is connected to the upper end of the mounting box 32. The axial direction of the threaded sleeve 33 is along the axial direction of the lead screw 31. The threaded sleeve 33 is fitted onto the outside of the lead screw 31, and its inner wall is threadedly connected to the lead screw 31. Therefore, when the lead screw 31 is rotated, it can move vertically up and down within the threaded sleeve 33, thus adjusting the vertical height of the horizontal plate 2 at the corresponding position.

[0067] Reference Figure 5 and Figure 6 A connecting shaft 342 is provided at the lower end of the lead screw 31. The connecting shaft 342 is housed within the mounting box 32 and is coaxial with the lead screw 31. A insertion groove 341 is provided at the lower end of the lead screw 31, extending axially along the lead screw 31. A insertion post 343 is provided at the end of the connecting shaft 342 facing the lead screw 31. The insertion post 343 is axially aligned with the connecting shaft 342. The insertion post 343 and the insertion groove 341 are inserted into each other axially along the lead screw 31, and the insertion post 343 is slidably connected to the inner wall of the insertion groove 341 axially along the lead screw 31. When the lead screw 31 and the connecting shaft 342 rotate synchronously, the side wall of the insertion post 343 abuts against the inner side wall of the insertion groove 341. The shapes of the insertion slot 341 and the insertion post 343 are matched. Any shape that enables the connecting shaft 342 to drive the lead screw 31 to rotate synchronously, while the insertion post 343 slides along its own axis within the insertion slot 341, is acceptable. In this application, both the insertion slot 341 and the insertion post 343 are cross-shaped.

[0068] A drive source 344 is provided at the end of the connecting shaft 342 away from the lead screw 31. The drive source 344 includes a first gear 3441 and a second gear 3442, which mesh with each other. The first gear 3441 is coaxially connected to the connecting shaft 342 and is located at the end of the connecting shaft 342 away from the lead screw 31. A driver 3443 is coaxially mounted on the second gear 3442. In this application, the driver 3443 is a hand crank. One end of the hand crank is coaxially connected to the second gear 3442, and the other end extends beyond the mounting box 32 and is rotatably connected to the mounting box 32. Therefore, when the hand crank is turned, the second gear 3442 can drive the first gear 3441, thereby driving the connecting shaft 342 to rotate and thus driving the lead screw 31. In this application, the driver 3443 can also be driven by a motor to achieve automatic lifting and lowering of the lead screw 31.

[0069] The implementation principle of this application embodiment is as follows: The mounting bracket 43 is installed on the horizontal plate 2 through the parallel connection component 44, ensuring that the mounting bracket 43 and the horizontal plate 2 are parallel to each other. Then, the horizontal plate 2 is raised to the same height by the adjustment mechanism 3, and the liquid level value in the liquid level tube 41 at each position is read. According to the liquid level value, the corresponding adjustment mechanism 3 is driven to realize the height adjustment of each position of the horizontal plate 2. The adjustment principle is as follows: if the liquid level value in the liquid level tube 41 is low, it means that the horizontal plate 2 is at a higher position, and the horizontal plate 2 is moved down by the adjustment mechanism 3 at this position; if the liquid level value in the liquid level tube 41 is high, it means that the horizontal plate 2 is at a lower position, and the horizontal plate 2 is moved up by the adjustment mechanism 3 at this position.

[0070] Example 2:

[0071] The difference between this embodiment and Embodiment 1 is that: a large-area multi-unit base leveling device, referring to... Figure 7 and Figure 8 In this embodiment, the pressure gauge 442 includes a mounting sleeve 4421 and an indicating sleeve 4424. A first sealing plate 4422 is provided at one end of the mounting sleeve 4421, which closes the opening at one end of the mounting sleeve 4421. An indicating window 4423 is provided through the outer wall of the mounting sleeve 4421. The length direction of the indicating window 4423 is arranged along the axial direction of the mounting sleeve 4421, and a plurality of pressure indicating graduations are provided at intervals along the length direction of the mounting sleeve 4421 on the side wall of the indicating window 4423. The indicating sleeve 4424 is coaxially arranged with the mounting sleeve 4421. One end of the indicating sleeve 4424 is inserted into the mounting sleeve 4421 and the inner wall of the indicating sleeve 4424 and the mounting sleeve 4421 are slidably connected along the axial direction of the mounting sleeve 4421. A second sealing plate 4425 is provided at the end of the indicating sleeve 4424 away from the mounting sleeve 4421, and the second sealing plate 4425 closes one end of the indicating sleeve 4424.

[0072] Reference Figure 7 and Figure 8 A compression spring 4426 is provided inside the mounting sleeve 4421. The compression spring 4426 is axially arranged along the axial direction of the mounting sleeve 4421, and its two ends are respectively inserted into the mounting sleeve 4421 and the indicator sleeve 4424. The two ends of the compression spring 4426 are respectively connected to the first sealing plate 4422 and the second sealing plate 4425.

[0073] Reference Figure 7 and Figure 8 A clearance hole 4427 is provided through the first sealing plate 4422 along its thickness direction, and the clearance hole 4427 passes through the first sealing plate 4422 and the second sealing plate 4425. The clearance hole 4427 is inserted into the connecting bolt 441, and the inner wall of the clearance hole 4427 is spaced apart from the outer wall of the connecting bolt 441. Along the axial direction of the connecting bolt 441, the first sealing plate 4422 abuts against the mounting bracket 43, and the second sealing plate 4425 abuts against the horizontal plate 2.

[0074] The implementation principle of this embodiment is as follows: When the pressure gauge 442 is installed on the connecting bolt 441, and the distance between the mounting bracket 43 and the horizontal plate 2 is adjusted by tightening the connecting bolt 441, the indicating sleeve 4424 will slide into the mounting sleeve 4421 along its own axis, and the compression spring 4426 can ensure that both ends of the pressure gauge 442 can abut against the mounting bracket 43 and the horizontal plate 2. The position of the indicating sleeve 4424 in the mounting sleeve 4421 can be viewed through the scale on the side of the indicating window 4423. Therefore, by using the pressure gauge 442 of embodiment 2 instead of the pressure sensor of embodiment 1, the mounting bracket 43 and the horizontal plate 2 can be manually adjusted to be parallel when power is unavailable.

[0075] Example 3:

[0076] The difference between this embodiment and Embodiment 1 is that: a large-area multi-unit base leveling device, referring to... Figure 9 and Figure 10 A liquid level sensor 45 is installed on the liquid level tube 41.

[0077] Reference Figure 10 and Figure 11 The adjustment mechanism 3 includes several hydraulic cylinders 35, which are arranged axially in the vertical direction. The lower end of the hydraulic cylinder 35 is connected to the base 1, and the upper end of the hydraulic cylinder 35 is provided with a precision compensation component 36.

[0078] Reference Figure 10 and Figure 11The precision compensation component 36 includes a compensation screw 362, a mounting base 361, and a connecting platform 363. The mounting base 361 is arranged vertically and its lower end is connected to the output shaft of the hydraulic cylinder 35. The compensation screw 362 is located on the side of the mounting base 361 facing the horizontal plate 2, and both ends of the compensation screw 362 are rotatably connected to the mounting base 361. One end of the compensation screw 362 is coaxially connected to a drive motor 364, and the compensation screw 362 is rotatably connected to the connecting platform 363, which is connected to the horizontal plate 2.

[0079] The implementation principle of this application embodiment is as follows: the liquid level in the liquid level tube 41 can be detected in real time by the liquid level sensor 45.
