[0037] Please see the attached Figure 1-7 In one embodiment, the present invention provides a torque coupling for a slab tracking system, comprising a first coupling mechanism 10, a second coupling mechanism 20 and a shell mechanism 30. First of all, it should be noted that since the connecting ends of the coupling are usually circular, the circumferential, radial and axial directions in this application are all based on the circular connecting end surface of the coupling; this is different from the prior art that uses tracking data from photoelectric tubes and tachometers to adjust the speed and direction of each furnace roller, and the photoelectric tubes need to use gas, which will result in a huge monthly consumption of compressed air energy, and this method is combined with a leather cup coupling with a short service life and high maintenance costs, especially in summer when the labor intensity is high. The present application solves the above-mentioned defects in the prior art by providing a torque coupling for a slab tracking system, as follows:

[0038] The first coupling mechanism 10 includes a first coupling joint 110, a coil assembly 120 and an induction circuit board 130, the second coupling mechanism 20 includes a second coupling joint 210 and a first permanent magnet 220, and the shell mechanism 30 includes a shell 310, a second permanent magnet 320 and a receiving circuit board 330; wherein, the first coupling joint 110 and the second coupling joint 210 both have a matching coupling channel 112, the inner side of the connecting end of the first coupling joint 110 has a plurality of first protrusions 111 arranged at intervals along the circumferential direction, a first groove is formed between two adjacent first protrusions 111, and both ends of each first protrusion 111 along the circumferential direction are recessed inward to form a blind hole, and the coil assembly 120 is arranged in each blind hole; wherein, each coil assembly 120 includes a coil 121 and a spring 122, the coil 121 is connected in the blind hole, the spring 122 is connected to the coil 121, and the induction circuit board 130 is connected to the outer side of the connecting end of the first coupling 110, and the induction circuit board 130 is electrically connected to the coil assembly 120; the inner side of the connecting end of the second coupling 210 has a plurality of second protrusions 211 arranged at intervals along the circumferential direction, and the first permanent magnets 220 are connected to both ends of the second protrusions 211 along the circumferential direction, the second protrusions 211 are engaged with the first grooves, and the first permanent magnet 220 is inserted into the spring 122; the shell 310 is sleeved on the coupling channel 112 of the first coupling 110 and is fitted with the connecting end of the first coupling 110, the second permanent magnet 320 and the receiving circuit board 330 are connected to the side of the shell 310 close to the first coupling 110, the receiving circuit board 330 is electrically connected to the induction circuit board 130, and the induction circuit board 130 is arranged between the first permanent magnet 220 and the second permanent magnet 320.

[0039] Specifically, the first coupling 110 and the second coupling 210 are both main components of the coupling mechanism. In order to facilitate the passage of the drive shaft of the components, both have matching coupling channels 112. The matching setting here means that the two coupling channels 112 are coaxially arranged and have the same size, so that the drive shaft of the component is passed through and installed in the coupling channels 112; and the inner side of the connecting end of the first coupling 110 has a plurality of first protrusions 111, which are used for the installation of the coil assembly 120. At the same time, the first protrusions 111 are arranged circumferentially to form first grooves, and the first grooves are used to insert the second protrusions 211 of the second coupling 210. Similarly, the plurality of second protrusions 211 on the inner side of the connecting end of the second coupling 210 are arranged circumferentially to form second grooves, and this second groove is used to insert the first protrusions 111, so that the first coupling 110 and the second coupling 210 are meshed.

[0040] Among them, each of the first protrusions 111 has blind holes formed by inward depressions at both ends along the circumferential direction for the installation of the coil assembly 120, and the first permanent magnets 220 are connected to both ends of the second protrusions 211 along the circumferential direction. When the shell 310 is sleeved on the coupling channel 112 of the first coupling handle 110, the second permanent magnet 320 and the receiving circuit board 330 inside it are also correspondingly close to the sensing circuit board 130. The second permanent magnet is used to provide a magnetic field for the sensing circuit board 130, so that the sensing circuit board 130 is correspondingly arranged between the first permanent magnet 220 and the second permanent magnet 320. When the coupling rotates, the sensing circuit board 130 cuts the magnetic lines of force between the first permanent magnet 220 and the second permanent magnet 320, and the receiving circuit board 330, the sensing circuit board 130 and the coil assembly 120 are electrically connected to form a closed circuit. Combined with Faraday's law of electromagnetic induction, the closed circuit will generate current at this time to facilitate the power supply and operation of the circuit board. ; The coil assembly 120 includes a coil 121 and a spring 122. In the no-load state, the furnace roller can be driven to rotate by relying on the adjusted preload force of the spring 122. When the slab passes by, the load increases, and the force will cause the contact surface of the first permanent magnet 220 to compress the spring 122, thereby extending into the coil 121. At this time, the magnetic flux in the coil 121 changes to generate current in the closed circuit, and the surface of the high-temperature (1100°C) slab is attached with a thick oxide film, which is bumpy and uneven, and exhibits friction changes on the roller. Therefore, the torque changes around a certain value at the microscopic level. This change causes the permanent magnet to reciprocate in the coil, and the magnetic flux changes differently. The coil will generate a changing current, and this changing current can be detected as a pulse signal. The receiving circuit board 330 is responsible for collecting the emitted pulse signal and transmitting it to the external monitoring host. The host generates a slab model by referring to the continuous casting coefficient based on the pulses emitted by adjacent rollers to achieve the purpose of slab tracking.

[0041] As a preferred embodiment of the present invention, one end of the first permanent magnet 220 inserted in the spring 122 is flush with one end of the spring 122 close to the coil 121 .

[0042] It should be noted that this allows the first permanent magnet 220 to directly extend into the coil 121 after the spring 122 is compressed due to the increased load when the slab passes, thereby avoiding the problem that the first permanent magnet 220 still cannot extend into the coil 121 after the spring 122 is compressed to the limit.

[0043] As a preferred embodiment of the present invention, the first permanent magnet 220 is cylindrical, and a shoulder 221 is formed at one end of the first permanent magnet 220 close to the second protrusion 211 .

[0044] It should be noted that the cylindrical shape can be easily matched with the spring 122 and the coil 121, so that it is convenient to insert, and the shoulder 221 can facilitate the installation of the first permanent magnet 220 and the second protrusion 211, and the shoulder 221 can serve as a contact surface to contact the spring 122. When the slab is subjected to load changes, it can directly squeeze the spring 122, thereby facilitating the first permanent magnet 220 to extend into the coil 121.

[0045] As a preferred embodiment of the present invention, the second coupling mechanism 20 also includes a wedge block 230, the second protrusion 211 is radially inwardly recessed to form a positioning groove 212, and the second protrusion 211 has through holes at both ends along the circumferential direction, the shoulder 221 of the first permanent magnet 220 is clamped in the through hole, and the wedge block 230 is installed in the positioning groove 212 and fixedly connected to the second protrusion 211 by bolts.

[0046] It is worth noting that, since the through hole is opened to facilitate the installation of the first permanent magnet 220, it is necessary to add the wedge block 230 to resist the first permanent magnet 220 so as to position and install the first permanent magnet 220. During installation, after the second coupling 210 and the first coupling 110 are engaged, the first permanent magnet 220 is inserted into the spring 122 of the blind hole from the positioning groove 212, and then the wedge block 230 is inserted into the positioning groove 212, and the wedge block 230 is fixed to the second coupling 210 with a bolt. The protrusion 211 is fixed; wherein, in a preferred embodiment, a pad 240 can be further provided. After the first permanent magnet 220 is inserted, the pad 240 is added to the first permanent magnet 220, and finally the wedge 230 is inserted, so that the pad 240 is connected to the through hole and is arranged between the first permanent magnet 220 and the wedge 230 to further ensure the positioning installation effect, and the preload force of the spring 122 can also be adjusted by adding a gasket (not shown) behind the adjustment pad 240.

[0047] As a preferred embodiment of the present invention, it further includes a takeover shield 40, which is sleeved on the coupling channel 112 of the second coupling coupler 210 and covers the outside of the connecting end of the second coupling coupler 210, and the takeover shield 40 is arranged to abut against the enclosure 310.

[0048] It is worth noting that the hand guard 40 is used to cooperate with the cladding 310 to form a sealing structure for the internal coupling hand structure, thereby avoiding metal dust pollution and affecting the service life. Therefore, the hand guard 40 is covered on the outside of the connecting end of the second coupling hand 210 and is arranged to be against the cladding 310; preferably, in order to make the connection between the hand guard 40 and the cladding 310 tight to ensure the sealing effect, the connection between the hand guard 40 and the cladding 310 can be reinforced by bolting.

[0049] Furthermore, the number of the sensing circuit boards 130 is six, and six first mounting grooves spaced apart along the circumferential direction are formed on the outer side of the connecting end of the first coupling 110 , and the sensing circuit boards 130 are connected to the first mounting grooves accordingly.

[0050] It should be understood that in the coupling, the number of the first protrusions 111 and the number of the second protrusions 211 are both six, and each of the sensing circuit boards 130 is correspondingly provided with a component position, so the number of the sensing circuit boards 130 is also six, and to facilitate the installation of the sensing circuit boards 130, six first mounting grooves arranged at intervals along the circumferential direction are opened on the outer side of the connecting end of the first coupling 110, so that each of the first mounting grooves corresponds to the installation of a sensing circuit board 130; it is worth mentioning that when the sensing circuit board 130 and the coil 121 are connected to each other by telecommunication, the circuit is arranged inside the first coupling 110, which is common knowledge known to those skilled in the art, so it is omitted in the drawings of this application and will not be described in detail.

[0051] Furthermore, six second installation slots spaced apart along the circumferential direction are formed on a side of the enclosure 310 close to the first coupling 110 , and each of the second installation slots is connected to the second permanent magnet 320 and the receiving circuit board 330 .

[0052] It should be noted that, in order to match the number of the induction circuit boards 130, the number of the second permanent magnets 320 and the receiving circuit boards 330 is also six. Therefore, six second mounting grooves spaced circumferentially are provided on the side of the enclosure 310 close to the first coupling 110 for easy installation.

[0053] Furthermore, the diameter of the coupling channel 112 is 50 mm to 70 mm.

[0054] It is understandable that the diameter of the coupling channel 112 can be determined according to the adaptable size of the drive shaft. Preferably, the diameter of the coupling channel 112 can be set to 50 mm to 70 mm, and those skilled in the art can make a selection according to actual needs.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
