Description

Technical Field

[0001] The present invention relates to process manufacturing, and particularly to a cable force self-monitoring cable clip system suitable for double-cable free connection. Background Art

[0002] In civil engineering, for two intersecting stay cables, fixtures are often used to connect and fix them. At present, most cable clips adopt a two-piece design, and the stay cables are fixed at the intersection of the two stay cables by connecting the upper and lower two cover plates. On the one hand, these cable clips cannot achieve free transformation of the connection angle and connection height. On the other hand, they only have a simple connection function. Aiming at the technical problem that the existing two-piece cable clip structure cannot achieve free changes in angle and height, a Chinese invention patent with the publication number CN201620512430 discloses a cross cable clip, which is applied to the confluence position of cross stay cables. The stay cables in two extending directions are fixed by a first stay cable fixture and a second stay cable fixture. At the same time, since the third clip on the second stay cable fixture is rotatably connected to the second clip on the first stay cable fixture, the first stay cable fixture and the second stay cable fixture can rotate adaptively to adapt to the relative angle between the stay cables, avoiding the bending of the stay cables. However, this cross cable clip has a simple structure and can only adjust the connection angle of the stay cables, and cannot adjust the connection height of the stay cables and damp vibration, and cannot be used in special environments. Therefore, the applicability of the cross cable clip is not high.

[0003] At the same time, in civil engineering, it is often necessary to monitor the cable force in the stay cables. Currently, common methods include the pressure sensor method, the vibration frequency method, the magneto-elastic effect method, etc. Among them, the magneto-elastic effect method has been widely used due to its non-contact measurement method, strong anti-interference ability, high measurement accuracy and other advantages. However, when the magneto-elastic effect method is currently used to monitor the cable force of stay cables, it is necessary to pre-penetrate an integrated magnetic flux sensor into the stay cable or wind a coil on the cable body on site, and the operation process is cumbersome. Therefore, proposing a clamp-type magnetic flux sensor can effectively improve the monitoring efficiency. The design of the clamp-type magnetic flux sensor is highly similar to the form of the cable clip in form. Introducing the connection function and the monitoring function into the cable clip at the same time has great application prospects.

[0004] Therefore, it can be seen that how to improve the applicability of the cross cable clip and quickly realize the monitoring of the cable force is a problem to be solved in this field. Summary of the Invention

[0005] Aiming at the technical problems that the existing cross cable clip has low applicability and only has a simple connection function, the purpose of the present invention is to provide a cable force self-monitoring cable clip system suitable for double-cable free connection, which can achieve the connection angle and connection gap of different double stay cables, and has a cable force self-monitoring function, which can enhance the applicability of the cable clip.

[0006] To achieve the above object, a cable force self-monitoring cable clip system applicable to double-cable free connection provided by the present invention includes a first fixing component, a second fixing component, a damping connection component, and several electromagnetic induction components; the several electromagnetic induction components are respectively arranged axially in the first fixing component and the second fixing component and are attached to the cables arranged in the first fixing component and the second fixing component to form a cable force self-monitoring structure; both ends of the damping connection component are respectively rotatably connected to the first fixing component and the second fixing component and generate relative acting forces on the first fixing component and the second fixing component, and the connection angle and gap between the two cables are controlled by the depth and angle of the relative rotation of the first fixing component and the second fixing component with respect to the damping connection component.

[0007] Further, the first fixing component or the second fixing component includes a magnetic flux cover plate and a cable magnetic flux fixing component, and the magnetic flux cover plate and the cable magnetic flux fixing component are relatively cooperatively connected to form an installation space for the cable.

[0010] Further, the first magnetic flux split body and the second magnetic flux split body cooperate with each other to form a cylindrical installation space for installing the cable.

[0011] Further, the electromagnetic induction component includes an excitation coil, an insulator, an induction coil, and an inner shaft body, the excitation coil is attached to the inner groove wall of the outer sleeve hose, the insulator is arranged on the excitation coil, the induction coil is attached to the insulator, and the inner shaft body is attached to the induction coil.

[0012] Further, the cable fixing connecting piece is also provided with connection threads with a small-diameter circumference and is cooperatively connected with the damping connection component.

[0013] Further, the damping connection assembly includes two connection heads and a connection spring; the two connection heads are respectively arranged at both ends of the connection spring and are respectively connected to the first fixing assembly and the second fixing assembly.

[0014] Further, internal threads are provided inside the two connection heads, and the internal threads are respectively adapted to the connection threads on the second magnetic flux split body in the first fixing assembly and the second fixing assembly, and can form a threaded connection with the connection threads.

[0015] Further, a deformable protective sleeve is coated on the periphery of the connection spring, which can drive the connection spring to generate deformation and energy consumption when the cable vibrates.

[0016] The cable force self-monitoring cable clamp system applicable to double-cable free connection provided by the present invention can realize the connection angles and connection gaps of different double cables by controlling the threaded connection depth, and has wide engineering applicability.

[0017] Secondly, the cable clamp is combined with the magnetic flux sensor, without the need to pre-sleeve the sensor or wind the coil on site later, which provides convenience for the later cable force monitoring while realizing the cable connection.

[0018] In addition, by setting the damping connecting piece in this solution, the driven displacement of the other cable caused by the excessive displacement of one cable is weakened, and while avoiding the generation of additional cable force, the cable system is energy-dissipated and damped.

[0029] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to specific drawings.

[0030] Aiming at the technical problem that the existing cross cable clips have low applicability, the purpose of the present invention is to provide a cable force self-monitoring cable clip system applicable to double-cable free connection, which can realize the connection angles and connection gaps of different double cables and can enhance the applicability of the present cable device.

[0031] Furthermore, the cable force self-monitoring cable clip system applicable to double-cable free connection includes a first fixing component, a second fixing component and a vibration damping connection component 3.

[0032] The first fixing component and the second fixing component are used to fix two cables 4, and the first fixing component and the second fixing component are connected through the vibration damping connection component 3.

[0033] See Figure 1 , the first fixing component or the second fixing component includes a magnetic flux cover plate 1, a cable magnetic flux fixing component 2, and the magnetic flux cover plate 1 and the cable magnetic flux fixing component 2 are relatively cooperatively connected to form an installation space for the cable 4.

[0034] See Figures 2 - 3 , the magnetic flux cover plate 1 includes a cable fixing cover plate 1-1, a plurality of first locking holes 1-2 and a first magnetic flux split body 1-3.

[0035] The first magnetic flux split body 1-3 is arranged on the cable fixing cover plate 1-1, and a plurality of first locking holes 1-2 are symmetrically arranged on both sides of the first magnetic flux split body 1-3 and on the cable fixing cover plate 1-1 for connecting with the cable magnetic flux fixing component 2 by a locking piece.

[0036] The first magnetic flux split body 1-3 is in the shape of a semi-circular ring column and is embedded in the cable fixing cover plate 1-1. It is used to cooperate with the cable magnetic flux fixing component 2 to form an installation space for the cable 4. The first magnetic flux split body 1-3 includes an outer sleeve hose 1-3-1.

[0037] The outer sleeve hose 1-3-1 is in the shape of a semi-circular ring column. There is an arc-shaped groove in the middle of its whole body. The groove surface is embedded in the cable fixing cover plate 1-1 towards the outside. The groove is adapted to the cross-sectional shape of the cable 4, and can embed the cable 4 inside the groove for stable connection and installation.

[0038] See Figure 4 , the cable magnetic flux fixing component 2 includes a cable fixing connector 2-1, several second locking holes 2-2 and a second magnetic flux split body 2-3.

[0039] The cable fixing connector 2-1 is provided with a semi-cylindrical groove. The second magnetic flux split body 2-3 is arranged in the semi-cylindrical groove of the cable fixing connector 2-1. Several second locking holes 2-2 are symmetrically arranged on both sides of the second magnetic flux split body 2-3 and are arranged on the cable fixing connector 2-1, and are used to cooperate with the first locking hole 1-2 on the cable fixing cover plate 1-1 for corresponding connection with a locking piece.

[0040] The structure of the second magnetic flux split body 2-3 is the same as that of the first magnetic flux split body 1-3, so it will not be elaborated in detail here.

[0041] The cable fixing connector 2-1 is also provided with connection threads 2-4 with a small diameter circumference, which are used to cooperate with the vibration damping connection component 3 for connection. The angle and height between the first fixing component and the second fixing component are adjusted through the cooperation connection between the connection threads 2-4 at the bottom of the cable fixing connector 2-1 and the vibration damping connection component 3.

[0042] After the cable fixing cover plate 1-1 is cooperatively connected with the cable magnetic flux fixing component 2, the first magnetic flux split body 1-3 and the second magnetic flux split body 2-3 cooperate with each other to form a cylindrical installation space for installing the connecting cable 4.

[0043] There are several segments of electromagnetic induction components in the cylindrical installation space formed between the first magnetic flux split body 1-3 and the second magnetic flux split body 2-3. The electromagnetic induction components are respectively arranged in the first magnetic flux split body 1-3 and the second magnetic flux split body 2-3 in a semi-set manner. When the first magnetic flux split body 1-3 and the second magnetic flux split body 2-3 are cooperatively connected, an electromagnetic induction coil is formed. Several segments of electromagnetic induction components are respectively independently axially arranged in the cylindrical installation space.

[0044] In this solution, by respectively and independently axially arranging several segments of electromagnetic induction components in the magnetic flux split body, the force condition of each segment of the cable can be fully sensed, ensuring the accuracy of the subsequent calculated cable force value.

[0045] Furthermore, no electromagnetic induction components may be provided in the middle section of the magnetic flux split body, and several sections of electromagnetic induction components may be axially provided at both ends of the magnetic flux split body respectively.

[0046] As an example, three sections of electromagnetic induction components are provided at the first end of the magnetic flux split body, and the distance between the three sections of electromagnetic induction components at the first end is M. Similarly, three sections of electromagnetic induction components are provided at the second end of the magnetic flux split body, and the distance between the three groups of electromagnetic induction components at the second end is M, where M is different from N.

[0047] By providing electromagnetic induction components with inconsistent distances at both ends of the magnetic flux split body respectively, the force conditions at each end can be compared later through data, and the most accurate cable force value can be calculated through the comparison.

[0048] The axial distribution structure of the electromagnetic induction components in the magnetic flux split body is not limited in this solution, and the specific structure selection can be determined according to the actual situation.

[0049] See Figures 5 - 6 , the electromagnetic induction component includes an excitation coil 1-3-2, an insulator 1-3-3, an induction coil 1-3-4, and an inner shaft body 1-3-5.

[0050] The excitation coil 1-3-2 is arranged in contact with the inner groove wall of the outer sleeve hose 1-3-1, the insulator 1-3-3 is arranged on the excitation coil 1-3-2, and the induction coil 1-3-4 is arranged in contact with the insulator 1-3-3. By arranging the insulator 1-3-3, the excitation coil 1-3-2 and the induction coil 1-3-4 are isolated to avoid signal interference between the excitation coil 1-3-2 and the induction coil 1-3-4, and to ensure the stability of the magnetic flux sensing process.

[0051] The inner shaft body 1-3-5 is arranged in contact with the induction coil 1-3-4, and the inner shaft body 1-3-5 can form a rigid attachment surface for the coil, so that the coil can be stably arranged in the magnetic flux split body.

[0052] Furthermore, when the first magnetic flux split body 1-3 and the second magnetic flux split body 2-3 are separated, the measurement function is not formed; during measurement, the first magnetic flux split body 1-3 and the second magnetic flux split body 2-3 are combined. Since the two magnetic flux split bodies are connected to form a loop, the excitation coil 1-3-2 and the induction coil 1-3-4 located within the first magnetic flux split body 1-3 and the second magnetic flux split body 2-3 come into contact and conduct. When an electric current is applied to the excitation coil 1-3-2, it is connected, that is, an electromotive force is generated at both ends of the induction coil 1-3-4. In this solution, an electromagnetic induction component is arranged between the first magnetic flux split body 1-3 and the second magnetic flux split body 2-3, and the electromagnetic induction component is used to monitor the cable force of the cable 4. When an alternating current or a pulsed current is applied to the excitation coil 1-3-2, according to Faraday's law of electromagnetic induction, an electromotive force is generated at both ends of the induction coil 1-3-4. The value of this electromotive force is related to the magnetic permeability of the steel member to be measured. When the stress state of the connected cable 4 changes, its magnetic permeability also changes significantly.

[0053] Here, the relationship between the internal force of the cable and the change in magnetic permeability Δμ satisfies the following formula:

[0054]

[0055] Where F is the internal force of the cable, E is the elastic modulus, A is the area of the steel cable, λ is the axial deformation constant; B is the saturation magnetization intensity, K is the uniaxial magnetic anisotropy constant, Δμ is the change in magnetic permeability, H is the magnetic field strength, and θ is the angle between the magnetic field and the easy magnetization axis.

[0056] In the formula, except for the force F on the steel member and the change in magnetic permeability Δμ, the rest are constants, indicating that there is indeed a linear correlation between the two, and the external force F of the steel member can be deduced by measuring the change in magnetic permeability Δμ.

[0057] By calibrating the corresponding relationship between the induced voltage value and the cable stress in the laboratory, the cable stress can be deduced according to the output induced voltage value.

[0058] Here, the corresponding relationship between the induced voltage value and the cable stress is related to various factors, such as the number of turns of the coil, the diameter of the coil, etc. The table corresponding to the corresponding relationship between the induced voltage value and the cable stress is factory-calibrated. Therefore, in actual application, the cable stress can be deduced according to the induced voltage value.

[0059] The present invention combines the cable clamp with the magnetic flux sensor, which can eliminate the need to pre-thread the sensor or wind the coil on-site later, providing convenience for cable force monitoring in the future while realizing the connection of the cable.

[0060] Connection threads 2-4 with a small-diameter circumference are provided on the second magnetic flux split body 2-3 of the first fixing component and the second fixing component. These connection threads 2-4 can be threadedly connected with the damping connection member 3.

[0061] See Figure 7 , the vibration damping connection member 3 includes two connection heads 3-1 and a connection spring 3-2.

[0062] The two connection heads 3-1 are respectively arranged at both ends of the connection spring 3-2. Internal threads are provided inside the two connection heads 3-1, and the internal threads are respectively adapted to the connection threads on the second magnetic flux component 2-3 in the first fixing component and the second fixing component, and can form a threaded connection with the connection thread 2-4.

[0063] The first fixing component and the second fixing component are respectively threadedly connected to both ends of the connection spring 3-2, and the two cable stays 4 arranged in the first fixing component and the second fixing component can be indirectly connected through the connection spring 3-2, which can weaken the driven displacement of the other cable stay 4 caused by excessive displacement of one cable stay 4, thereby improving the reliability of the cable stay 4 during operation.

[0064] At the same time, by controlling the rotation depth, i.e., the angle, of the connection thread 2-4 on the two fixing components in the connection head 3-1, the relative connection angle and gap between the two cable stays 4 can be controlled, and the applicability of the device can be improved.

[0065] The connection spring 3-2 is used for energy dissipation and vibration damping of the cable stay system. When one of the connected cable stays 4 vibrates during the operation of the cable stay 4, it drives the connection spring 3-2 to deform, achieving the effect of energy dissipation and vibration damping.

[0066] Secondly, when the connection spring 3-2 is in a normal state, when it is connected to the second magnetic flux component 2-3 at both ends, it will have a certain pressing effect on the cable stay magnetic flux fixing component 2, which can ensure the connection tightness between the magnetic flux cover plate 1 and the cable stay magnetic flux fixing component 2.

[0067] Furthermore, a deformable protective sleeve 3-3 is coated on the periphery of the connection spring 3-2. The deformable protective sleeve 3-3 is used to protect the connection spring 3-2. On the one hand, it can adapt to the deformation of the connection spring 3-2 driven by the vibration of the cable stay 4. On the other hand, it can reduce the risk of failure of the connection spring 3-2 caused by environmental changes, and can avoid affecting the stability of the operation of this cable stay device.

[0068] Moreover, in this solution, the deformable protective sleeve 3-3 is preferably used, which can deform following the deformation of the connection spring 3-2 due to the acting force of the cable stay 4 and will not affect the operation of the connection spring 3-2.

[0069] In summary, the cable force self-monitoring cable clip system applicable to the free connection of double cables can realize the connection angle and connection gap of different double cable stays, well solve the problems existing in the prior art, and greatly enhance the applicability of this cable stay device.

[0070] The following is an example to illustrate its working process in specific applications. However, it should be noted here that the following content is only a specific application example of this solution and does not limit this solution.

[0071] First, place the first cable in the magnetic flux cover plate 1 and the cable magnetic flux fixing component 2, connect the magnetic flux cover plate 1 and the cable magnetic flux fixing component 2 in cooperation, and place the first cable in the first fixing component.

[0072] Specifically, embed the first cable in the groove of the second magnetic flux split body 2-3. After placement, set the first magnetic flux split body 1-3 corresponding to the second magnetic flux split body 2-3, place the first cable in the cylindrical installation space formed between the first magnetic flux split body 1-3 and the second magnetic flux split body 2-3, and fit it with the electromagnetic induction component in the cylindrical installation space. Then, through the locking parts on the first magnetic body 1-3 and the second magnetic body 2-3 corresponding to the locking parts, the first magnetic flux 1-3 and the second magnetic body 2-3 are tightly connected.

[0073] The installation structure of the second cable is the same as that of the first cable, so it will not be elaborated here in detail.

[0074] Thread-connect the installed first cable and the second cable through the connection thread 2-4 on the second magnetic body 2-3 and the connection heads 3-1 at both ends of the connection spring 3-4. The relative angle and clearance of the two cables 4 are satisfied by the rotation depth and angle of the connection thread 2-4 inside the connection head 3-1.

[0075] After adjustment, when the cable works, when one of the connected cables 4 vibrates, it drives the belt stiffness damping connection spring 3-2 to deform, achieving the effect of energy dissipation and vibration damping. At the same time, when the cable clamp is to be used for cable force monitoring, when an alternating current or pulsed current is passed into the excitation coil 1-3-2, according to Faraday's law of electromagnetic induction, an induced electromotive force will be generated at both ends of the induction coil 1-3-4. The value of this electromotive force is related to the magnetic permeability of the measured steel member. When the stress state of the connected cable 4 changes, its magnetic permeability will also change significantly. By calibrating the corresponding relationship between the induced voltage value and the cable stress in the laboratory, the cable stress can be calculated based on the output induced voltage value.

[0076] The cable force self-monitoring cable clamp system applicable to the free connection of double cables composed of the above solution has the following beneficial effects compared with the prior art:

[0077] (1) The present invention can realize the connection angle and connection clearance of different double cables by controlling the thread connection depth, and has wide engineering applicability.

[0078] (2) The present invention combines a cable clip with a magnetic flux sensor, eliminating the need to pre-sleeve the sensor or wind coils on-site later. While achieving the connection of the stay cables, it provides convenience for the later monitoring of the cable forces.

[0079] (3) By providing a vibration damping connecting member, the present invention weakens the driven displacement of another stay cable caused by excessive displacement of one cable. While avoiding the generation of additional cable forces, it dissipates energy and dampens vibrations for the stay cable system.

[0080] (4) The connecting spring in the vibration damping connecting member of the present invention has a certain pressing effect on the cable magnetic flux fixing assembly, which can ensure the tightness of the connection between the magnetic flux cover plate and the cable magnetic flux fixing assembly.

[0081] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only for illustrating the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and all these changes and improvements fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
