Supporting tube wall analysis method and supporting tube

Abstract

The invention relates to a supporting tube wall analysis method and a supporting tube, and a shearing model of a structure center line is generated by establishing communication connection with a database of the center line of a supporting tube composite structure. When the supporting pipe bears shearing force, if the geometrical shape of the supporting pipe changes suddenly, such as a shaft shoulder, a hole and the like, the stress concentration phenomenon can be generated. In a high shear stress concentration area, the actual shear stress borne by the material is far higher than nominal shear stress. The local high shear stress enables a crystal structure in the material to distort and slip, and after a certain number of cycles, fatigue cracks are generated in weak links such as defect positions or grain boundaries of the material. And the pipe wall parameters of the center line of each supporting pipe combination structure are obtained, so that the weight of the supporting pipes under the same load is reduced, and the defects that the weight of the supporting pipes is large, and the strength of the supporting structures is small are overcome.

Description

Technical Field

[0001] The present application relates to the technical field of simulation, and particularly to a method for analyzing the wall of a support pipe and a support pipe. Background Art

[0002] During the process of emergency rescue, scenarios such as building collapse, ground subsidence, and tunnel collapse often occur. At this time, rescue personnel cannot predict the possibility of secondary disasters occurring to damaged structures, so a support device composed of discrete support pipes is used to build temporary safety supports. Facing a relatively poor rescue environment, it is difficult for the support pipe transportation tools of emergency rescue personnel to transport the support pipes to the designated rescue environment in a timely manner. These designated rescue environments are generally key areas where disasters have occurred. These areas often have relatively poor traffic conditions. Therefore, it is necessary to solve the current dilemma that the support pipes are heavy, but the structural strength of the supports is small, and large-load professional transportation equipment is required, and to propose a method for analyzing the wall of a support pipe and a support pipe. Summary of the Invention

[0003] Based on this, it is necessary to solve the current dilemma that the support pipes are heavy, but the structural strength of the supports is small, and large-load professional transportation equipment is required, and to propose a method for analyzing the wall of a support pipe and a support pipe.

[0014] This application relates to a load-bearing threaded support device, including:

[0015] A support column, including a sleeve, a threaded pipe, and a limit nut. The threaded pipe is arranged inside the sleeve. The inner ring surface of the limit nut is threadedly connected to the outer peripheral surface of the threaded pipe, and the limit nut is clamped at the top end of the sleeve;

[0016] A medium valve, connected to the bottom of the sleeve. The medium valve is arranged at one end away from the limit nut.

[0019] This application relates to a method for analyzing the wall of a support pipe and a support pipe. By establishing a communication connection with a database of the center line of the support pipe combined structure, a shear model of the structure center line is generated. When the support pipe bears shear force, if there are sudden changes in the geometric shape of the support pipe, such as at parts like shoulders and holes, stress concentration phenomena will occur. In high shear stress concentration areas, the actual shear stress borne by the material will be much higher than the nominal shear stress. This local high shear stress will cause distortion and slip of the crystal structure inside the material. After a certain number of cycles, fatigue cracks will initiate at weak links such as material defects or grain boundaries. Based on the shear model of the structure center line, a force model of the support pipe and a force model of the support pipe combination are constructed, and the forces of different support pipe materials can be simulated, simulating the force models of the support pipe and the support pipe combination based on the shear model of the structure center line. Simply put, obtain the data vector of the center line of the selected support pipe combined structure. Based on the data vector and the target load-bearing upper limit of the support pipe wall, incorporate the data vector into the analysis script to obtain the wall parameters of each support pipe combined structure center line, thereby reducing the weight of the support pipe under the same load, which solves the defect that the support pipe has a large weight while the structural strength of the support is small.

[0034] In order to make the objectives, technical solutions, and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. 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.

[0035] The present application provides a method for analyzing the wall thickness of a support pipe.

[0036] AsFigure 1 As shown in Figure 1 , in an embodiment of the present application, a method for analyzing the wall of a support pipe includes:

[0037] S100, establishing a communication connection with the database of the center line of the support pipe combined structure.

[0038] S200, generating a shear model of the structural center line.

[0039] S300, constructing a force model of the support pipe and a force model of the support pipe combination based on the shear model of the structural center line.

[0040] S400, selecting the material of the support pipe.

[0041] S500, determining the data vector of the center line of the support pipe combined structure based on the force model of the support pipe and the selected material of the support pipe.

[0042] S600, returning the material of the support pipe until all the materials to be selected for the support pipe are selected. S700, obtaining the data vector of the selected center line of the support pipe combined structure.

[0043] S800, incorporating the data vector into the analysis script based on the data vector and the target bearing capacity upper limit of the support pipe wall.

[0044] S900, obtaining the wall parameters of each center line of the support pipe combined structure.

[0045] This embodiment relates to a method for analyzing the wall of a support pipe. By establishing a communication connection with the database of the center line of the support pipe combined structure, a shear model of the structural center line is generated. When the support pipe bears shear force, if there are sudden changes in the geometric shape of the support pipe, such as at the shoulder, hole and other parts, stress concentration will occur. In the high shear stress concentration area, the actual shear stress borne by the material will be much higher than the nominal shear stress. This local high shear stress will cause distortion and slip of the crystal structure inside the material. After a certain number of cycles, fatigue cracks will initiate at the defects or grain boundaries and other weak links of the material. Based on the shear model of the structural center line, a force model of the support pipe and a force model of the support pipe combination are constructed, which can simulate different materials of the support pipe, and simulate the force model of the support pipe and the force model of the support pipe combination based on the shear model of the structural center line. Simply put, obtaining the data vector of the selected center line of the support pipe combined structure, incorporating the data vector into the analysis script based on the data vector and the target bearing capacity upper limit of the support pipe wall, and obtaining the wall parameters of each center line of the support pipe combined structure, thereby reducing the weight of the support pipe under the same load, which solves the defect that the support pipe has a large weight while the supporting structural strength is small.

[0046] In an embodiment of the present application, after S100, the method includes:

[0047] S111, call the data database based on the center line of the support pipe combination structure.

[0048] S112, based on the structural center line in the database of the support pipe combination structure center line, call the microscopic characterization database of metal materials.

[0049] S113, use the center line shear force curvature analysis data in the database of the support pipe combination structure center line to call the analysis script.

[0050] Specifically, the damping characteristics of different metals vary greatly. For example, common structural metal materials such as steel have relatively moderate damping performance, and their damping mainly comes from the dislocation movement and grain boundary slip inside the metal. When the metal is vibrated, dislocations move in the metal lattice and interact with other defects in the lattice, thereby consuming vibration energy. Some special alloys, such as aluminum metal, aluminum alloy, etc., may have higher damping performance due to their special crystal structure and composition, and are suitable for support instrument components with higher vibration reduction requirements.

[0051] In an embodiment of the present application, after S100, the method further includes:

[0052] S121, establish a data storage pool.

[0053] S122, incorporate the data of the received data database and the data of the microscopic characterization database of metal materials into the data storage pool.

[0054] S123, establish a mapping relationship between the data in the data storage pool and the analysis script.

[0055] Specifically, for metal materials, a smaller grain size usually leads to higher damping performance. This is because smaller grains mean more grain boundaries, and during vibration, grain boundaries can effectively hinder dislocation movement, increase internal friction, and thus improve the damping ability. For example, metal materials produced by the grain refinement treatment process can better absorb and consume energy in a vibrating environment.

[0056] Defects such as dislocations, vacancies, and impurities in crystals have an important impact on damping performance. Dislocations interact with defects during movement, forming various complex microstructural changes, thereby consuming vibration energy. For example, in a metal material containing a large number of dislocations, when vibrated, the interaction between dislocations will be more intense, causing energy to be dissipated in the form of heat energy, etc., improving the damping effect.

[0057] When fitting the damage caused by the shear force generated by mechanical external forces such as these vibrations to the support pipe, the microscopic characterization database of metallic materials can provide raw data.

[0058] In one embodiment of the present application, S123 includes:

[0059] S131, based on the data in the material database, select length parameters regarding different length values of the structural centerline.

[0060] Specifically, the unit of the length parameter is decimeter. The length parameter of the structural centerline is a length value.

[0061] The length value of a structural centerline can be 1 decimeter or 2 decimeters.

[0062] S132, select a length parameter with a length value. The unit of the length parameter is decimeter.

[0063] S133, generate a structural centerline regarding this length parameter.

[0064] S134, based on the length parameter of the structural centerline and the analysis script, determine the optimal metallic material in the microscopic characterization database of metallic materials.

[0065] S135, return the length parameter with the selected length value until all length values are selected.

[0066] Specifically, different length values of the structural centerline will affect two issues. One is the resonance of the external mechanical vibration to the support pipe under the centerline with different length values, and the other is the influence of the resonance on the material crystal.

[0067] Vibration frequency is one of the important factors affecting the damping performance of materials. In different frequency ranges, the damping mechanism of materials may change. In the low-frequency range, the damping of materials mainly comes from the viscosity of the materials and the relaxation process of the internal structure. For example, some viscoelastic materials show high damping performance during low-frequency vibration as their molecular chain segments have enough time to adjust and move.

[0068] As the frequency increases, the material may undergo resonance, resulting in a sharp drop in the damping performance. In the high-frequency range, the damping performance of the material may also change due to the internal microscopic inertia effect and the wave propagation characteristics. For example, some composite materials show specific damping characteristics during high-frequency vibration due to the inertia difference between different phases and the wave scattering effect.

[0069] For metallic materials, smaller grain sizes generally result in higher damping performance. This is because smaller grains mean more grain boundaries, and during vibration, grain boundaries can effectively hinder dislocation movement, increase internal friction, and thus improve the damping capacity. For example, metallic materials produced through grain refinement treatment processes can better absorb and dissipate energy in a vibrating environment.

[0070] Defects such as dislocations, vacancies, and impurities in crystals have an important impact on damping performance. Dislocations interact with defects during movement, forming various complex microstructural changes, thereby consuming vibration energy. For example, in metallic materials containing a large number of dislocations, when subjected to vibration, the interaction between dislocations will be more intense, causing energy to be dissipated in the form of heat energy, etc., improving the damping effect.

[0071] Different phase compositions and phase interface characteristics have a significant impact on damping performance. For example, in metal matrix composites, the type, distribution of the reinforcement phase, and the interfacial bonding state with the matrix all affect damping performance. If the interfacial bonding between the reinforcement phase and the matrix is strong, the interface can effectively transfer loads and generate friction during vibration, thereby increasing damping. Conversely, if the interfacial bonding is weak, relative sliding may occur at the interface, which can also consume vibration energy.

[0072] In an embodiment of the present application, S200 includes:

[0073] S210, calling a length parameter of a length value.

[0074] S220, using a topological algorithm to perform vector analysis on the three-dimensional structure data.

[0075] Specifically, the topological algorithm includes one or more of the Poisson surface reconstruction algorithm and the Delaunay triangulation algorithm.

[0076] S230, obtaining a data vector of the centerline of the selected support tube combination structure.

[0077] S240, returning the length parameter of the called length value until all length values have been called.

[0078] S250, generating at least one shear model of the structure centerline.

[0079] Specifically, the Poisson surface reconstruction algorithm is based on implicit functions and Poisson equations. This algorithm converts point cloud data into a voxel representation and uses Poisson equations to reconstruct the surface. The Poisson equation is a partial differential equation that describes the relationship between the Laplace operator and the divergence of a function. By solving the Poisson equation, a smooth surface model can be obtained to match the original point cloud data as closely as possible.

[0080] The function of the topology algorithm is to define an indicator function for the topology algorithm, which takes positive values inside the model and negative values outside. The zero isosurface is the surface of the model. However, directly calculating the gradient field will cause infinite values at the surface edges of the vector field. Therefore, first perform a smoothing filter convolution on the indicator function, and then calculate the gradient field of the smoothed function. According to Gauss divergence theory, the gradient of the smoothed indicator function is equal to the vector field obtained from the smoothed surface normal field. This can obtain at least one shear model of the structural centerline.

[0081] In an embodiment of the present application, the topology algorithm includes one or more of the Poisson surface reconstruction algorithm and the Delaunay triangulation algorithm.

[0082] In an embodiment of the present application, S300 includes:

[0083] S310, call the shear model of the structural centerline.

[0084] S320, receive the three-dimensional environment of the point traces of the analysis script based on the RGB-D analysis program.

[0085] S330, determine the connection function of the three-dimensional environment of the point traces of the analysis script based on the RGB-D analysis program.

[0086] S340, based on the connection function and the Delaunay triangulation algorithm, obtain the vector analysis of the shear model of the structural centerline.

[0087] S350, use the vector analysis results of the three-dimensional structure data to construct the force model of the support pipe and the force model of the support pipe combination.

[0088] Specifically, it combines a color camera and a depth sensor, can simultaneously obtain the color information and depth information of an object, and generate a point cloud containing color attributes. It is commonly used in fields such as robot vision and augmented reality to help robots or virtual scenes better understand the surrounding environment.

[0089] Based on the RGB-D analysis program, a three-dimensional environment of the point traces of the shear model of the structural centerline can be formed.

[0090] In an embodiment of the present application, the selected material of the support pipe includes one or more of aluminum metal, iron metal, and steel alloy in the microscopic characterization database of metal materials.

[0091] In an embodiment of the present application, S800 includes:

[0092] S810, based on the elastic modulus reduction algorithm, obtain the target force range of the three-dimensional structure data of the support pipe combination structure centerline.

[0093] S820. Determine the upper limit of the target bearing capacity of the support pipe wall using the generalized yield function and the target stress range.

[0094] In an embodiment of the present application, S800 further includes:

[0095] S830. Establish a mapping relationship between the data in the data storage pool and the analysis script.

[0096] S840. Import the upper limit of the target bearing capacity of the support pipe wall into the analysis script.

[0097] S850. Import the microscopic characterization database of the metal material into the analysis script.

[0098] S860. Import the centerline shear stress curvature analysis data into the analysis script.

[0099] Specifically, in an actual mechanical structure, it often bears the combined action of multiple loads such as tensile force, pressure, and shear force. This multi-tube stress state makes the fatigue behavior of the material more complex. For example, a beam under a bending load has both normal stress (generated by the bending moment) and shear stress (generated by the shear force) on its cross-section. In this complex stress state, the direction and magnitude of the principal stress of the material change continuously, making the initiation and propagation directions of fatigue cracks in the material more complex.

[0100] When the normal stress and shear stress have the same sign (i.e., both are tensile or compressive), they will promote each other and accelerate the initiation and propagation of fatigue cracks. When they have different signs, although they will cancel out part of the stress to a certain extent, they will still have an adverse effect on the fatigue performance of the material.

[0101] S870. Obtain the analysis script to be analyzed.

[0102] Specifically, under the action of shear force, the material will undergo shear deformation. For metal materials, this repeated shear deformation will cause the dislocations inside the material to continuously move and multiply. The movement of dislocations intersects and tangles with each other, forming microscopic structures such as dislocation cells. The changes in these microscopic structures will cause the material to exhibit work hardening or softening phenomena.

[0103] When the material is in a work-hardened state, its hardness increases but its toughness decreases, which makes the material more prone to brittle fracture under subsequent shear force cycles; while material softening will cause the shape of the part to change, affecting the normal fit and operating accuracy of the machine. As the number of shear force cycles increases, the fatigue damage of the material accumulates continuously. When the damage reaches a certain level, the part will undergo fatigue failure.

[0104] The present application provides a heavy-thread support device.

[0105] Such as Figure 2As shown, in an embodiment of the present application, a load-bearing threaded support includes a support column 100 and a medium valve 200.

[0106] The support column 100 includes a sleeve 110, a threaded pipe 120, and a limit nut 130. The threaded pipe 120 is disposed inside the sleeve 110. The inner ring surface of the limit nut 130 is threadedly connected to the outer peripheral surface of the threaded pipe 120, and the limit nut 130 is clamped at the top end of the sleeve 110.

[0107] Specifically, in some usage states, the sleeve 110 and the threaded pipe 120 can both be connected to a stepped ring platform (not shown in the figure) through connecting pins 410.

[0108] In fact, the stepped ring platform can be a pipe fitting, and annular grooves are provided on the outer sidewall of these pipe fittings, thereby forming the stepped ring platform.

[0109] The medium valve 200 is connected to the bottom of the sleeve 110. The medium valve 200 is disposed at one end away from the limit nut 130. A through groove 140 is provided at the bottom of the sleeve 110. The central axis of the through groove 140 coincides with the central axis of the sleeve 110, and the medium valve 200 is in communication with the through groove 140.

[0110] The first connecting member 300 is connected to the end of the threaded pipe 120. The first connecting member 300 is disposed at one end away from the medium valve 200.

[0111] The second connecting member 400 is connected to the bottom of the sleeve 110. The second connecting member 400 is disposed at one end away from the limit nut 130.

[0112] This embodiment relates to a load-bearing threaded support. The sleeve 110, the threaded pipe 120, and the limit nut 130 of the support column 100 in the load-bearing threaded support form a relatively compact load-bearing body. The threaded pipe 120 and the limit nut 130 are threadedly connected to each other to form a threaded connection load-bearing structure, and the threaded connection can withstand relatively large longitudinal and transverse stresses. The limit nut 130 is clamped at the top of the sleeve 110, and the force between the limit nut 130 and the sleeve 110 can be unidirectional, which greatly reduces the probability of separation between the limit nut 130 and the sleeve 110 in the vertical direction. The medium valve 200 can fill the inner cavity of the sleeve 110 with pressure medium to enhance the connection force between the threaded pipe 120 and the limit nut 130. In this application, the inner cavity of the sleeve 110 can be filled with low-pressure air, or the air in the inner cavity of the sleeve 110 can be extracted to form a negative pressure in the inner cavity of the sleeve 110. The first connector 300 is connected to the end of the threaded pipe 120, and the second connector 400 is connected to the bottom of the sleeve 110. It solves the problem that the structural strength of the support structure built by traditional discrete rods is weak, and it is often unable to effectively provide support and protection force in scenarios such as building collapse, ground subsidence, and tunnel collapse.

[0113] As Figure 1 shown, in an embodiment of the present application, the outer peripheral surface of one end of the threaded pipe 120 close to the medium valve 200 is smooth. A first accommodation ring groove 121 is provided at one end of the threaded pipe 120 close to the medium valve 200. The first accommodation ring groove 121 is connected with a sealing ring 122. The sealing ring 122 abuts against the inner peripheral surface of the sleeve 110.

[0114] Specifically, the outer peripheral surface of one end of the threaded pipe 120 is smooth. A first accommodation ring groove 121 can be provided at this end, and the first accommodation ring groove 121 is connected with a sealing ring 122. The sealing ring 122 is used to seal the medium between the sealing ring 122 and the medium valve 200.

[0115] The sealing ring 122 is arranged between the outer peripheral surface of the smooth threaded pipe 120 and the inner side wall of the sleeve 110.

[0116] It is worth mentioning that by using the space plane passing through the central axis of the threaded pipe 120 to intersect with the threaded part of the threaded pipe 120, the intersecting section of the threaded part of the threaded pipe 120 is trapezoidal, and this trapezoidal threaded part can greatly enhance the load-bearing level of the load-bearing threaded support in the plumb line direction.

[0117] Using high-pressure medium can also enhance the load-bearing level of the load-bearing threaded support in the plumb line direction.

[0118] In an embodiment of the present application, the medium between the sealing ring 122 and the medium valve 200 includes normal-pressure air, high-pressure air, or hydraulic oil.

[0119] Specifically, in one usage scenario, the medium between the sealing ring 122 and the medium valve 200 can be high-pressure air or hydraulic oil, which can enhance the load-bearing magnitude of the load-bearing threaded support in the plumb line direction.

[0120] In another usage scenario, the medium between the sealing ring 122 and the medium valve 200 can be normal-pressure air, which can utilize the trapezoidal-threaded portion to enhance the load-bearing magnitude of the load-bearing threaded support in the plumb line direction.

[0121] In the third usage scenario, the medium between the sealing ring 122 and the medium valve 200 can be evacuated to form a negative pressure between the sealing ring 122 and the medium valve 200. This makes it difficult for the sleeve 110 and the limit nut 130 to become detached.

[0122] As Figure 1 shown, in an embodiment of the present application, the sleeve 110 is provided with at least one connecting groove 111. The connecting groove 111 is arranged away from the limit nut 130. The connecting groove 111 is arranged close to the medium valve 200.

[0123] Specifically, the connecting groove 111 can be used to accommodate the connecting pin 410 so that the end of the sleeve 110 can be connected to other functional connecting parts.

[0124] In an embodiment of the present application, the sleeve 110 is provided with a plurality of connecting grooves 111, and the plurality of connecting grooves 111 are in the same working plane. The extension line of the central axis of each connecting groove 111 passes through the central axis of the sleeve 110.

[0125] Specifically, the plurality of connecting grooves 111 are in the same working plane, and the extension line of the central axis of each connecting groove 111 passes through the central axis of the sleeve 110. This type of connecting groove 111 is used to fixedly connect other functional connecting parts.

[0126] As Figures 3 to 5 shown, it is also possible to use one connecting groove 111. In this case, the connecting groove 111 is hinged to other functional connecting parts through the connecting pin 410.

[0127] As Figure 7As shown, in an embodiment of the present application, the load-bearing threaded support further includes a profiled steel 510 and a secondary support beam 520. The profiled steel 510 includes a bottom wall 511, a first side wall 512, and a second side wall 513. The bottom wall 511 is fixedly connected between the first side wall 512 and the second side wall 513. The bottom wall 511 is perpendicular to the first side wall 512. The bottom wall 511 is perpendicular to the second side wall 513. The first side wall 512 and the second side wall 513 are both disposed on the same side of the bottom wall 511. The secondary support beam 520 has the same structure as the support column 100.

[0128] Specifically, for a support structure with the load-bearing threaded support as the structural basis, the stability of a triangle can be utilized to support the box body.

[0129] Holes for connecting bolts are provided on both the first side wall 512 and the second side wall 513 of the profiled steel 510. By using these holes for connecting bolts, the profiled steel 510 can be hinged to the second connecting member 400. The profiled steel 510 can be hinged to the end of the threaded pipe 120 of the secondary support beam 520.

[0130] The sleeve 110 and the threaded pipe 120 can move relative to each other to change the length of the support column 100 or the length of the secondary support beam 520.

[0131] In an embodiment of the present application, the second connecting member 400 is hinged to the top of the profiled steel 510. The secondary support beam 520 is hinged to the bottom of the profiled steel 510. The secondary support beam 520 is fixedly connected to the sleeve 110. The first connecting member 300 abuts against the ground.

[0132] Specifically, the secondary support beam 520 is fixedly connected to the sleeve 110, and the extension line of the central axis of each connecting groove 111 passes through the central axis of the sleeve 110. This type of connecting groove 111 is used for fixedly connecting other functional connecting members. One connecting groove 111 can also be used. In this case, the connecting groove 111 is hinged to other functional connecting members through connecting pins 410. In this working state, the other functional connecting members are used to connect the secondary support beam 520 and the sleeve 110.

[0133] As Figure 6 shown, in an embodiment of the present application, the first connecting member 300 includes a channel steel 310. The channel steel 310 includes a first section 311, a second section 312, and a third section 313. The first section 311 is fixedly connected between the second section 312 and the third section 313.

The second section 312 and the third section 313 are both disposed on the same side of the first section 311.

[0134] Specifically, during the emergency rescue process, scenarios such as building collapse, ground subsidence, and tunnel collapse are often encountered. The support column 100, the first connector 300, and the second connector 400 can form a separate support device.

[0135] The channel steel 310 includes a first section 311, a second section 312, and a third section 313. The first section 311 is fixedly connected between the second section 312 and the third section 313. The first section 311 is perpendicular to the second section 312, and the first section 311 is perpendicular to the third section 313. Both the second section 312 and the third section 313 are arranged on the same side of the first section 311. The first section 311, the second section 312, and the third section 313 of the channel steel 310 can surround and support the structural beam to be supported.

[0136] In an embodiment of the present application, the first connector 300 further includes an annular connection portion 320. The annular connection portion 320 is fixedly connected to the first section 311. The first section 311 is arranged between the second section 312 and the annular connection portion 320. The annular connection portion 320 is sleeved on one end of the threaded pipe 120. The annular connection portion 320 is arranged away from the medium valve 200.

[0137] Specifically, the shaped connection portion is fixedly connected to the first section 311. The first section 311 is arranged between the second section 312 and the annular connection portion 320. The annular connection portion 320 is sleeved on one end of the threaded pipe 120. The annular connection portion 320 is arranged away from the medium valve 200.

[0138] Based on the threaded connection between the threaded pipe 120 and the limit nut 130, a threaded connection force-bearing structure is formed. The threaded connection can withstand large longitudinal and transverse stresses. The limit nut 130 is clamped at the top of the sleeve 110. The force between the limit nut 130 and the sleeve 110 can be one-way, which greatly reduces the probability of separation between the limit nut 130 and the sleeve 110 in the vertical direction. The medium valve 200 can fill the inner cavity of the sleeve 110 with pressure medium to enhance the connection force between the threaded pipe 120 and the limit nut 130.

[0139] In an embodiment of the present application, the second connector 400 includes a connecting nail 410, a collar 420, and a bottom plate 430. The collar 420 is connected to the bottom of the sleeve 110. The collar 420 is connected to the bottom plate 430. The connecting nail 410 penetrates through the connecting portion of the collar 420 and the connecting portion of the bottom plate 430.

[0140] Specifically, the collar 420 and the bottom plate 430 are connected by one or more connecting nails 410.

[0141] The collar 420 and the base plate 430 are connected by a connecting pin 410, and the collar 420 and the base plate 430 can rotate relative to each other.

[0142] The collar 420 and the base plate 430 are connected by a plurality of connecting pins 410, and the collar 420 and the base plate 430 are fixed to each other.
