Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown: an intelligent detection and alarm device for rope position deviation of a ropeway wire rope wheel groove, comprising a frame 1, a rope pulley 3 is installed inside the frame 1, and a wire rope body 2 is arranged on the top of the rope pulley 3, two assembly mechanisms 5 are symmetrically installed on the top of the frame 1, a second mounting frame 4 is installed between the two assembly mechanisms 5, a locking mechanism 6 is installed at the bottom of the assembly mechanism 5, and a positioning member 7 is installed at the bottom of the locking mechanism 6; The assembly mechanism 5 includes a bottom plate 52 and two support rods 51 symmetrically fixedly connected to the top thereof. The outer surfaces of the two support rods 51 are sleeved with mounting sleeves 551. A third mounting frame 55 is fixedly connected between the two mounting sleeves 551. A first fixing plate 53 is arranged at the top center of the third mounting frame 55. A mounting groove 552 is provided at the top center of the third mounting frame 55. Two rails 553 are fixedly connected to both sides of the mounting groove 552. A first sliding groove 534 is provided on the inner side of the first fixing plate 53. The first sliding groove 534 is slidably connected to the rail 553. Both ends of the first fixing plate 53 are provided with movable holes 531. The movable holes 532 are provided at the bottom center of the third mounting frame 55. A fixing block 532 is fixedly connected to one end of the inner side of the movable hole 531, and a positioning rod 54 is slidably connected to one end of the inner cavity of the movable hole 531. A spring 533 is arranged in the inner cavity of the movable hole 531, and the spring 533 is located between the positioning rod 54 and the fixing block 532. A first inclined surface 541 is fixedly connected to one side of one end of the positioning rod 54, and a second inclined surface 542 is fixedly connected to one side of one end of the positioning rod 54. A plurality of limiting blocks 56 are fixedly connected to the opposite sides of the two support rods 51. An eccentric wheel 57 is arranged inside the mounting groove 552. A handle 58 is rotatably connected to the center of the top of the first fixing plate 53, and the bottom end of the handle 58 is fixedly connected to the eccentric wheel 57.

[0023] In this embodiment, in the design of the lifting rope position detection effect and the height control of the alarm 41, the specific adjustment mechanism is realized by a series of ingenious mechanical structures. First, the position of the alarm 41 can be adjusted by manual operation. When the user pulls the handle 58, the handle 58 drives the eccentric wheel 57 to rotate. Since the design of the eccentric wheel 57 causes its rotation center to deviate from the connection position with the handle 58, the rotation of the eccentric wheel 57 will cause eccentric movement in the mounting groove 552. The cooperation between the eccentric wheel 57 and the first fixing plate 53 enables the first fixing plate 53 to slide on the top of the third mounting frame 55, thereby providing a basis for height adjustment of the alarm 41.

[0024] In this process, the sliding of the first fixed plate 53 not only adjusts the height of the alarm 41, but also indirectly drives the position change of the positioning rod 54. One end of the positioning rod 54 is designed with two inclined surfaces at different angles - a first inclined surface 541 and a second inclined surface 542. By switching the positions of these inclined surfaces, the positioning rod 54 can be flexibly moved up and down. The middle part of the positioning rod 54 switches positions between two limit blocks 56. When the first inclined surface 541 is located between the limit blocks 56, the positioning rod 54 can move up. Conversely, when the second inclined surface 542 is located between the limit blocks 56, the positioning rod 54 can move downward. The limit blocks 56 cause the positioning rod 54 to slide in the movable hole 531 through the relative force between the positioning rod 54. This sliding movement is eventually transmitted to the internal spring 533, generating elastic compression.

[0025] The spring 533, in a compressed state, provides a restoring elastic force for the positioning rod 54, so that the positioning rod 54 can return to its initial position in the unlocked state. This design ensures accurate control of the height of the alarm 41 when the middle of one end of the positioning rod 54 is locked. When the height of the alarm 41 needs to be adjusted to adapt to different cableways and cableway components, the user can adjust the positioning rod 54 to achieve quick and convenient positioning of the alarm 41.

[0026] Through this design, once a change in the rope position is detected, the alarm 41 can respond in time and send out an alarm signal. This alarm mechanism can effectively improve the real-time monitoring effect of the rope position and reduce safety hazards in equipment operation. During use and maintenance, the convenience and flexibility of this structural design also greatly improve the operating efficiency of the alarm 41, enabling it to adapt to a variety of different ropeway detection needs, and help improve the accuracy and reliability of the overall detection system.

[0027] Embodiment 2: Figure 6 and Figure 7As shown, the locking mechanism 6 includes a housing 61, a cylinder 62 is provided at the top of the inner cavity of the housing 61, both ends of the cylinder 62 are rotatably connected to movable rods 65, the bottom ends of the two movable rods 65 are rotatably connected to the first linkage rod 67, one end of the first linkage rod 67 is rotatably connected to the third support frame 661, the middle of the movable rod 65 is rotatably connected to the second support frame 651, and the top of the housing 61 is fixedly connected to the third mounting frame 55. The side wall of the housing 61 is fixedly connected to the second mounting frame 4, the side wall of the movable rod 65 is fixedly connected to the housing 61, an alarm 41 is slidably installed inside the second mounting frame 4, and one end of the alarm 41 is threadedly connected to two mounting threaded rods 42. A fixed rod 68 is fixedly connected to the inside of the top of the movable rod 65, one end of the fixed rod 68 is rotatably connected to the second linkage rod 69, and the bottom end of the second linkage rod 69 is rotatably connected to the first support frame 631. A slide bar 64 is fixedly connected to the center of the bottom of the inner cavity of the shell 61, and a lifting sleeve 63 is slidably connected to the outer surface of the slide bar 64. The outer side of the lifting sleeve 63 is fixedly connected to the first support frame 631. Second slide grooves 611 are provided on both sides of the bottom of the shell 61. A sliding block 66 is slidably connected to the inner side of the second slide groove 611, and one side of the sliding block 66 is fixedly connected to the third support frame 661.

[0028] In this embodiment, when the magnetic flux changes, the alarm 41 will immediately detect the change and send a signal to the control system, so that the cylinder 62 receives the operation command and starts quickly. The action of the cylinder 62 drives the internal piston to push the movable rod 65, so that the two movable rods 65 move to both sides at the same time under the action of the reaction force. With the movement of the movable rod 65, the two movable rods 65 swing around the central axis of the second support frame 651, generating a synchronous swing force.

[0029] During this process, the first linkage rod 67 connected to the bottom end is also driven, and the first linkage rod 67 transmits the force to the sliding block 66 through the third support frame 661, so that the sliding block 66 starts to move along the preset path. When moving, the sliding block 66 is restricted and guided by the second slide groove 611 to achieve stable linear motion. The guiding function of the second slide groove 611 ensures that the sliding block 66 moves smoothly along the set linear direction, avoiding any lateral deviation, so as to ensure the accuracy of control.

[0030] Due to the synchronous swinging of the two movable rods 65, the two sliding blocks 66 also move synchronously and move toward each other during this process. The approach of the sliding blocks 66 drives the positioning member 7 connected at the bottom to gradually approach the wire rope body 2. The close contact between the positioning member 7 and the wire rope body 2 increases the friction force, so that when the wire rope deflects greatly, the braking force can be quickly applied to prevent the wire rope from slipping or falling off. This braking process responds to the deviation in a timely manner to ensure the stability and safety of the system operation.

[0031] During the movement of the movable rod 65, the synergistic effect of the fixed rod 68 is also introduced. The fixed rod 68 drives the movement of the second linkage rod 69, and further enables the second linkage rod 69 to cooperate with the first support frame 631 to jointly apply a force to the lifting sleeve 63. Since the lifting sleeve 63 is in close contact with the outer surface of the slide rod 64, the lifting sleeve 63 slides smoothly along the outer surface of the slide rod 64 under the push of the force. Through this design, while controlling the linear movement of the sliding block 66 and the position of the positioning member 7, the sliding of the lifting sleeve 63 also plays a stabilizing and guiding role, ensuring the smooth operation and precise control of the entire system.

[0032] Embodiment 3: According to Figure 2 and Figure 8 As shown, the positioning member 7 includes a second fixed plate 71, a first arc groove 75 is provided on one side of the second fixed plate 71, a first arc block 721 is slidably connected inside the first arc groove 75, a first movable block 72 is fixedly connected to one end of the first arc block 721, a second arc groove 76 is provided on both ends of the side wall of the first movable block 72, a second arc block 731 is slidably connected inside the second arc groove 76. A second movable block 73 is fixedly connected to one end of the second arc block 731, two third arc grooves 77 are provided on both ends of the side wall of the second movable block 73, a third arc block 741 is slidably connected inside the third arc groove 77, and a third movable block 74 is fixedly connected to one end of the third arc block 741. The cable pulley member 3 includes a connecting frame 34, a cable pulley 31 is provided on both sides of the connecting frame 34, the cable pulley 31 is located below the wire rope body 2, two swing rods 36 are rotatably connected to the top of the connecting frame 34, and a first mounting frame 32 is rotatably connected to one side of the cable pulley 31. The top of the swing rod 36 is rotatably connected to a limit wheel 33 , and the two limit wheels 33 are respectively located on both sides of the wire rope body 2 . A tension spring 35 is arranged below the wire rope body 2 , and both ends of the tension spring 35 are respectively hung with the bottom end of the swing rod 36 .

[0033] In this embodiment, when the positioning member 7 approaches the wire rope body 2, the third arc block 741 can effectively change the angle of the third movable block 74 by sliding on the inner side of the third arc groove 77. This design allows the angle of the third movable block 74 to be adjusted according to the contact situation of the wire rope body 2, thereby achieving more accurate positioning and restraint. When the wire rope body 2 contacts the positioning member 7, the reaction force of the wire rope body 2 will cause the third arc groove 77 and the third movable block 74 to move together. This movement mechanism ensures that the positioning member 7 can adapt to the changes of the wire rope body 2 during the contact process, thereby enhancing the control of the wire rope.

[0034] Similarly, the second arc block 731 can also slide in the second arc groove 76 to adjust the position of the second movable block 73. This design allows the second arc block 731 and the second movable block 73 to cooperate flexibly during the movement, ensuring that the positioning member 7 can effectively contact the wire rope body 2 and automatically adjust its shape and angle under the action of the reaction force, further enhancing the locking effect.

[0035] In addition, the sliding function of the first arc block 721 allows the position of the first movable block 72 to be flexibly adjusted as needed. Through the coordinated force of the first movable block 72 and the second movable block 73, the positioning member 7 can cover the surface of the wire rope body 2. The coordinated movement of these four movable blocks ensures that the positioning member 7 can fully and evenly contact the wire rope body 2, thereby increasing the contact area and significantly improving the locking effect.

[0036] This design of multiple arc blocks and movable blocks enables the system to automatically adjust under different working conditions, providing a stable and efficient locking function. Through reasonable coordination of activities and reaction forces, the positioning member 7 can accurately lock the wire rope body 2, avoiding any unnecessary offset or looseness, and ensuring error-free rope position detection. At the same time, this flexible adjustment mechanism can adapt to the size or shape changes of different wire ropes, providing high adaptability and reliability, and effectively improving overall safety and service life.

[0037] The use method and working principle of the device: In order to improve the accuracy of rope position detection, the height of the alarm 41 can be accurately controlled. When adjusting the position of the alarm 41, the handle 58 can be first pulled so that the handle 58 drives the eccentric wheel 57 to rotate. At this time, the eccentric wheel 57 will move inside the mounting groove 552, because the connection between the eccentric wheel 57 and the handle 58 is not at the center of the handle 58, and the horizontal position of the third mounting frame 55 remains unchanged, which will produce a reaction force on the first fixed plate 53. Since the first slide groove 534 and the track 553 can slide relative to each other, the first fixed plate 53 can slide on the top of the third mounting frame 55. In this process, the first fixed plate 53 will also indirectly change the position of the positioning rod 54. When the middle part of the positioning rod 54 is between the two limit blocks 56, the positioning rod 54 is in a locked state; when it is switched to the first inclined surface 541 and is located between the two limit blocks 56, the positioning rod 54 can be easily moved upward; similarly, when it is switched to the second inclined surface 542, the positioning rod 54 can move downward. During the up and down movement, the positioning rod 54 is acted upon by the stop block 56, thereby pushing it to slide in the movable hole 531 and indirectly compressing the spring 533. At this time, the positioning rod 54 can also use the elasticity of the spring 533 to push itself against the support rod 51 and remain between the two stop blocks 56, so that when the middle of one end of the positioning rod 54 is locked, the height of the alarm 41 can be adjusted.

[0038] Like this, can adjust to suitable position according to different ropeways and ropeway assemblies during installation and use, guarantee the detection of rope position.At the same time, when detecting position change, alarm device 41 can send out alarm signal in time.

[0039] When the height of the alarm 41 is adjusted, when the changing magnetic field passes through the coil, an induced electromotive force is generated in the coil. When detecting the deviation of the rope position of the ropeway wire rope body 2, the sensor generates an alternating magnetic field. When the wire rope body 2 approaches or moves away from the magnetic field of the sensor, the distribution of the magnetic field will change because the wire rope body 2 is made of metal. According to Lenz's law, the magnetic field generated by the induced current always hinders the change of the magnetic flux that causes the induced current. This change in the magnetic field will cause the induced electromotive force in the sensor coil to change, and this change is closely related to the distance between the wire rope and the sensor.

[0040] When the magnetic flux changes, the alarm 41 can detect it in time and send a signal to prompt the cylinder 62 to quickly receive the operation command. The operation of the cylinder 62 will push the movable rod 65, so that the two movable rods 65 can move at the same time by using the reaction force, and swing around the second support frame 651 as the center. This will drive the first linkage rod 67 connected to the bottom end to start moving. When the first linkage rod 67 transmits the force to the sliding block 66 through the third support frame 661, the sliding block 66 will start to move. During the sliding process, the sliding block 66 will also be restricted and guided by the second slide groove 611 to ensure its linear motion.

[0041] Therefore, as the two movable rods 65 swing at the same time, the movement of the two sliding blocks 66 can be controlled at the same time and made to approach each other, so that the two sliding blocks 66 drive the positioning member 7 connected at the bottom to approach the wire rope body 2. The contact between the positioning member 7 and the wire rope body 2 increases the friction force, and the brake can be applied in time when the deviation is large to prevent the wire rope from falling off.

[0042] When the positioning member 7 approaches the wire rope body 2, the angle of the third movable block 74 can be changed by sliding the third arc block 741 inside the third arc groove 77. Similarly, the second arc block 731 can also move in the second arc groove 76, so that the third arc groove 77 not only maintains a vertical state, but also can move the third arc groove 77 and the third movable block 74 through the reaction force of the wire rope body 2 when approaching the wire rope body 2. In addition, the first arc block 721 can slide in the first arc groove 75, which is convenient for changing the position of the first movable block 72. Through the synergistic effect of the first movable block 72 and the second movable block 73, one positioning member 7 can use four movable blocks to cover the wire rope body 2, increase the contact area and improve the locking effect.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
