Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0031] Embodiment one: refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 : a cable steel wire rope wheel groove rope position deviation intelligent detection alarm device, comprising a frame 1, the frame 1 inner side is provided with a cable wheel part 3, and the top of the cable wheel part 3 is provided with a steel wire rope main body 2, the top of the frame 1 is symmetrically provided with two assembly mechanisms 5, two assembly mechanisms 5 are installed between the second mounting bracket 4, the bottom end of the assembly mechanism 5 is provided with a locking mechanism 6, and the bottom of the locking mechanism 6 is provided with a positioning part 7;

[0032] The assembling mechanism 5 comprises a bottom plate 52 and two support rods 51 fixedly connected to the top of the bottom plate 52, the outer surfaces of the two support rods 51 are sleeved with mounting sleeves 551, the third mounting frame 55 is fixedly connected between the two mounting sleeves 551, the first fixed plate 53 is arranged at the top of the third mounting frame 55, the mounting groove 552 is arranged at the top of the third mounting frame 55, the two sides of the mounting groove 552 are fixedly connected with two tracks 553, the first sliding groove 534 is arranged in the inner side of the first fixed plate 53, the first sliding groove 534 is in sliding connection with the track 553, the active hole 531 is arranged at the two ends of the first fixed plate 53, the fixed block 532 is fixedly connected to one end of the inner side of the active hole 531, the positioning rod 54 is in sliding connection with one end of the inner cavity of the active hole 531, the spring 533 is arranged in the inner cavity of the active hole 531 and located between the positioning rod 54 and the fixed block 532, the first inclined surface 541 is fixedly connected to one side of one end of the positioning rod 54, the second inclined surface 542 is fixedly connected to one side of one end of the positioning rod 54, the plurality of limiting blocks 56 are fixedly connected to the opposite sides of the two support rods 51, the eccentric wheel 57 is arranged in the inner side of the mounting groove 552, the handle 58 is rotatably connected to the top of the first fixed plate 53, and the handle 58 is fixedly connected to the eccentric wheel 57.

[0033] In the embodiment, in the design of improving the detection effect of the lifting rope and controlling the height of the alarm 41, the specific adjustment mechanism is realized through a series of ingenious mechanical structures. First, the position of the alarm 41 can be adjusted manually. When the user pulls the handle 58, the handle 58 drives the eccentric wheel 57 to rotate. Because the design of the eccentric wheel 57 makes the rotation center deviate from the connection position with the handle 58, the rotation of the eccentric wheel 57 will cause eccentric motion in the mounting groove 552. The cooperation of the eccentric wheel 57 and the first fixed plate 53 enables the first fixed plate 53 to slide on the top of the third mounting frame 55, thereby providing the basis for height adjustment of the alarm 41.

[0034] 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 of different angles, i.e., the first inclined surface 541 and the 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 the two limiting blocks 56, when the first inclined surface 541 is located between the limiting blocks 56, the positioning rod 54 can move up, and vice versa, when the second inclined surface 542 is located between the limiting blocks 56, the positioning rod 54 can move down. The limiting blocks 56 make the positioning rod 54 slide in the active hole 531 through the relative force, and this sliding motion is finally transmitted to the internal spring 533, generating elastic compression.

[0035] The spring 533 provides a reset elastic force for the positioning rod 54 in the compressed state, so that the positioning rod 54 can return to the initial position in the unlocked state. This design ensures the accurate control of the height of the alarm 41 when locking the middle part of one end of the positioning rod 54. When it is necessary to adjust the height of the alarm 41 to adapt to different cableways and cableway components, the user can quickly and conveniently position the alarm 41 by adjusting the positioning rod 54.

[0036] Through this design, once the change of the rope position is detected, the alarm 41 can respond in time and issue an alarm signal. This alarm mechanism can effectively improve the real-time monitoring effect of the rope position and reduce the safety hidden danger in the operation of the equipment. The convenience and flexibility of the structure design also greatly improve the operation efficiency of the alarm 41 during use and maintenance, so that it can adapt to various cableway detection requirements and help to improve the accuracy and reliability of the overall detection system.

[0037] Embodiment two: Figure 6 and Figure 7 As shown in FIG. 6, the locking mechanism 6 includes a shell 61, the inner cavity of the shell 61 is provided with a pneumatic cylinder 62 at the top end, two movable rods 65 are rotatably connected at both ends of the pneumatic cylinder 62, the bottom ends of the two movable rods 65 are rotatably provided with first linkage rods 67, one end of each first linkage rod 67 is rotatably connected with a third support frame 661, the middle part of each movable rod 65 is rotatably connected with a second support frame 651, and the top of the shell 61 is fixedly connected with the third mounting frame 55. The side wall of the shell 61 is fixedly connected with the second mounting frame 4, the side wall of each movable rod 65 is fixedly connected with the shell 61, the second mounting frame 4 is slidably installed with the alarm 41 on the inner side, and the alarm 41 is threadedly connected with two mounting threaded rods 42 at one end. The inner side of the top end of each movable rod 65 is fixedly connected with a fixed rod 68, one end of the fixed rod 68 is rotatably connected with a second linkage rod 69, and the bottom end of the second linkage rod 69 is rotatably connected with a first support frame 631. The bottom center of the inner cavity of the shell 61 is fixedly connected with a sliding rod 64, the sliding rod 64 is slidably connected with a lifting sleeve 63 on the outer surface, and the outer side of the lifting sleeve 63 is fixedly connected with the first support frame 631. Second sliding grooves 611 are formed on both sides of the bottom of the shell 61, and sliding blocks 66 are slidably connected in the inner sides of the second sliding grooves 611. One side of each sliding block 66 is fixedly connected with the third support frame 661.

[0038] In this embodiment, when the magnetic flux changes, the alarm 41 can immediately detect the change and issue a signal to the control system, so that the pneumatic cylinder 62 receives the operation instruction and starts quickly. The action of the pneumatic cylinder 62 drives the internal piston to push the movable rods 65, so that the two movable rods 65 move to both sides under the action of the reaction force. With the movement of the movable rods 65, the two movable rods 65 swing around the center axis of the second support frame 651 to generate synchronous swinging force.

[0039] In this process, the first linkage rod 67 connected at the bottom 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. The sliding block 66 is limited and guided by the second sliding groove 611 when moving, realizing stable straight-line motion. The guiding function of the second sliding groove 611 ensures the smooth movement of the sliding block 66 along the set straight-line direction, avoiding any lateral deviation to ensure the accuracy of control.

[0040] Due to the synchronous swinging of the two movable rods 65, the two sliding blocks 66 also move synchronously and move towards each other in this process. The approach of the sliding block 66 drives the bottom-connected positioning member 7 to gradually approach the steel wire rope body 2, and increases the friction force through the close contact between the positioning member 7 and the steel wire rope body 2, so that when the steel wire rope deviation is large, the braking force can be quickly applied to avoid the steel wire rope from slipping or falling off. This braking process responds to the deviation in time to ensure the stability and safety of the system operation.

[0041] In the movement process of the movable rod 65, the cooperative action of the fixed rod 68 is also introduced. The fixed rod 68 drives the movement of the second linkage rod 69, further enabling the second linkage rod 69 to cooperate with the first support frame 631 to apply force to the lifting sleeve 63. Since the lifting sleeve 63 is in close contact with the outer surface of the sliding rod 64, the lifting sleeve 63 smoothly slides along the outer surface of the sliding rod 64 under the push of the force. Through this design, while controlling the straight-line motion 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 accurate control of the entire system.

[0042] Example Three: According to Figure 2 and Figure 8As shown, the positioning member 7 includes a second fixed plate 71, one side of which is provided with a first arc-shaped groove 75, and the inner side of the first arc-shaped groove 75 is slidably connected with a first arc-shaped block 721, one end of the first arc-shaped block 721 is fixedly connected with a first movable block 72, and the side walls of the first movable block 72 are both provided with a second arc-shaped groove 76, and the inner side of the second arc-shaped groove 76 is slidably connected with a second arc-shaped block 731. One end of the second arc-shaped block 731 is fixedly connected with a second movable block 73, and the side walls of the second movable block 73 are both provided with two third arc-shaped grooves 77, and the inner side of the third arc-shaped groove 77 is slidably connected with a third arc-shaped block 741, and one end of the third arc-shaped block 741 is fixedly connected with a third movable block 74. The cable pulley member 3 includes a connecting frame 34, and the connecting frame 34 is provided with a cable pulley 31 on both sides, and the cable pulley 31 is located below the steel wire rope main body 2, and the connecting frame 34 is rotatably connected with two swing rods 36 at the top, and the cable pulley 31 is rotatably connected with a first mounting bracket 32 on one side. The top of the swing rod 36 is rotatably connected with a limiting wheel 33, and the two limiting wheels 33 are respectively located on both sides of the steel wire rope main body 2, and a tension spring 35 is arranged below the steel wire rope main body 2, and the two ends of the tension spring 35 are respectively hung with the bottom ends of the swing rods 36.

[0043] In this embodiment, when the positioning member 7 approaches the steel wire rope main body 2, the third arc-shaped block 741 can effectively change the angle of the third movable block 74 by sliding in the third arc-shaped groove 77. This design allows the angle of the third movable block 74 to be adjusted according to the contact condition of the steel wire rope main body 2, thereby achieving more accurate positioning and constraint. When the steel wire rope main body 2 contacts the positioning member 7, the reaction force of the steel wire rope main body 2 will cause the third arc-shaped groove 77 and the third movable block 74 to move together, and this movement mechanism ensures that the positioning member 7 can adapt to the changes of the steel wire rope main body 2 during contact, thereby enhancing the control force on the steel wire rope.

[0044] Similarly, the second arc-shaped block 731 can also slide in the second arc-shaped groove 76 to adjust the position of the second movable block 73. This design allows the second arc-shaped block 731 and the second movable block 73 to cooperate flexibly during movement, ensuring that the positioning member 7 can effectively contact the steel wire rope main body 2 and automatically adjust its shape and angle under the action of the reaction force, further enhancing the locking effect.

[0045] In addition, the sliding function of the first arc-shaped block 721 allows the position of the first movable block 72 to be flexibly adjusted as needed. Through the cooperative force of the first movable block 72 and the second movable block 73, the positioning member 7 can cover the surface of the steel wire rope main body 2. The cooperative movement of the four movable blocks ensures that the positioning member 7 can comprehensively and uniformly contact the steel wire rope main body 2, thereby increasing the contact area and significantly improving the locking effect.

[0046] The design of the multi-arc block and the movable block enables the system to automatically adjust under different working conditions, providing stable and efficient locking function. Through reasonable movement and reaction force matching, the positioning member 7 can accurately lock the steel wire rope body 2, avoiding any unnecessary deviation or looseness, ensuring no error in the rope position detection process. At the same time, this flexible adjustment mechanism can adapt to different sizes or shape changes of the steel wire rope, providing high adaptability and reliability, effectively improving the overall safety and service life.

[0047] The method of using the device and its working principle: 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 to rotate the eccentric wheel 57. At this time, the eccentric wheel 57 will move inside the installation slot 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 generate a reaction force on the first fixed plate 53. Since the first sliding 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 also indirectly changes 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 the locked state; when switching to the first inclined surface 541 and making it between the two limit blocks 56, the positioning rod 54 can be easily moved upward; similarly, when switching to the second inclined surface 542, the positioning rod 54 can be moved downward. During the upward and downward movement, the positioning rod 54 will be subjected to the force of the limit 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 limit blocks 56, so as to adjust the height of the alarm 41 when locking the middle part of one end of the positioning rod 54.

[0048] In this way, during installation and use, it can be adjusted to the appropriate position according to different cableways and cableway components to ensure the detection of the rope position. At the same time, when a position change is detected, the alarm 41 can timely send an alarm signal.

[0049] When adjusting the height of the alarm 41, an induced electromotive force will be generated in the coil when the changing magnetic field passes through the coil. When detecting the deviation of the rope position of the cableway steel wire rope body 2, the sensor will generate an alternating magnetic field. When the steel wire rope body 2 approaches or moves away from the magnetic field of the sensor, the distribution of the magnetic field will change due to the metal material of the steel wire rope body 2. 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 magnetic field will cause a change in the induced electromotive force in the sensor coil, and this change is closely related to the distance between the steel wire rope and the sensor.

[0050] 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 operation instructions. The operation of the cylinder 62 will push the movable rod 65, so that the two movable rods 65 move simultaneously by using the reaction force to swing around the second support frame 651 as the center. This will drive the first linkage rod 67 connected at the bottom 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 is also limited and guided by the second sliding groove 611 to ensure its straight-line movement.

[0051] Therefore, with the simultaneous swinging of the two movable rods 65, the movement of the two sliding blocks 66 can be controlled simultaneously, and they approach each other, so that the two sliding blocks 66 drive the positioning member 7 connected at the bottom to approach the steel wire rope body 2. Through the contact between the positioning member 7 and the steel wire rope body 2, the friction force is increased, which can brake in time when the deviation is large, avoiding the steel wire rope from falling off.

[0052] When the positioning member 7 approaches the steel wire rope body 2, the third arc-shaped block 741 slides inside the third arc-shaped groove 77 to change the angle of the third movable block 74. Similarly, the second arc-shaped block 731 can also move in the second arc-shaped groove 76, so that the third arc-shaped groove 77 not only remains vertical, but also moves with the third movable block 74 through the reaction force of the steel wire rope body 2 when it approaches the steel wire rope body 2. In addition, the first arc-shaped block 721 can slide in the first arc-shaped groove 75 to change the position of the first movable block 72. Through the cooperation of the first movable block 72 and the second movable block 73, one positioning member 7 can wrap the steel wire rope body 2 with four movable blocks, increase the contact area and improve the locking effect.

[0053] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
