In severe cases, it can lead to production stoppage and greatly affect the safe and stable operation of the equipment. Utility Model Content

[0004] This invention addresses the problem that bolts and pins on pulleys are prone to coming loose, causing the entire pulley to detach, the cable to fall to the ground, drag, and damage the cable. It proposes a cable-dragging pulley device with a detachment detection function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a towing cable trolley device with a detachment detection function, including a trolley body and a guide rail. The trolley body is movably connected to the guide rail and can move along the guide rail. The guide rail has a first end and a second end opposite to each other along its length. The device also includes an anti-detachment mechanism, which includes a traction steel wire rope and an anti-detachment detection component. The anti-detachment detection component includes a fixed frame, a moving block, a control module, a displacement detection module, and an alarm module. The displacement detection module and the alarm module are both connected to the control module. One end of the traction steel wire rope is fixed to the first end, and the other end is fixedly connected to the moving block. The fixed frame is fixed to the second end, and the moving block is movably connected to the fixed frame. The trolley body is movably connected to the traction steel wire rope. The traction steel wire rope can drive the moving block to move on the fixed frame. The displacement detection module is fixed to the fixed frame and is used to detect at least the displacement change of the moving block and transmit the displacement signal to the control module. After receiving the displacement signal, the control module controls the alarm module to issue an alarm message.

[0007] Furthermore, the fixed frame includes a fixed housing, which is fixedly connected to the second end. The fixed housing has a movable space, and the movable block is movably connected in the movable space. The displacement detection module includes a proximity switch, which is fixed on one end face of the movable space relative to the movable block.

[0008] Furthermore, the anti-detachment detection component includes a fixed rod, one end of which is fixedly connected to a traction steel wire rope. The fixed rod is movable within the moving space, and a moving block is fixedly connected to the fixed rod. The fixed rod passes through the fixed box along its own axial direction.

[0009] Furthermore, the anti-detachment detection component also includes an elastic element, which is sleeved on the fixed rod and located between the side wall of the moving block and the moving space. When the moving block moves toward the guide rail, the elastic element is in an elastic contraction state.

[0010] Furthermore, the movable block is provided with a guide block, and the fixed box is provided with a guide groove that cooperates with the guide block. The guide groove extends along the moving direction of the movable block, and the guide block can move along the guide groove.

[0014] Furthermore, the alarm module includes a buzzer and an alarm light.

[0015] Furthermore, there are at least two anti-detachment mechanisms, which are respectively located on opposite sides of the trolley body.

[0016] As can be seen from the above technical solutions, the advantages of this utility model are:

[0017] This invention features traction steel wire ropes at both ends of the guide rail, with the trolley body movably connected to the traction steel wire ropes. This allows the traction steel wire ropes to protect the trolley body and prevent it from detaching, thus preventing it from falling directly to the ground and damaging the cable in a short time. Furthermore, a movable block is installed at one end of the traction steel wire rope. A displacement detection module can monitor the displacement changes of the movable block in real time and accurately. This allows for the detection of the displacement signal of the movable block at the moment the trolley body detaches, which is promptly transmitted to the control module. An alarm module then alerts the operator to the detachment, providing maintenance personnel with sufficient time for repair and restoration, thus improving the timeliness and accuracy of detachment detection.

Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] Please see Figures 1-3 A cable trolley device with a detachment detection function includes a trolley body 100 and a guide rail 200. The trolley body 100 is movably connected to the guide rail 200 and can move along the guide rail 200. The guide rail 200 has a first end 210 and a second end 220 along its length. The device also includes an anti-detachment mechanism 300, which includes a traction steel wire rope 310 and an anti-detachment detection component. The anti-detachment detection component includes a fixed frame 321, a moving block 322, a control module 323, a displacement detection module 324, and an alarm module 325. The displacement detection module 324 and the alarm module 325 are both connected to the control module. 323 connection, one end of the traction wire rope 310 is fixed to the first end 210, and the other end is fixedly connected to the moving block 322. The fixed frame 321 is fixed to the second end 220. The moving block 322 is movably connected to the fixed frame 321. The trolley body 100 is movably connected to the traction wire rope 310. The traction wire rope 310 can drive the moving block 322 to move on the fixed frame 321. The displacement detection module 324 is fixed to the fixed frame 321. The displacement detection module 324 is at least used to detect the displacement change of the moving block 322 and transmit the displacement signal to the control module 323. After receiving the displacement signal, the control module 323 controls the alarm module 325 to issue an alarm message.

[0026] In this embodiment, as Figure 1 , Figure 3As shown, the trolley body 100 is movably connected to the guide rail 200 through a roller or slider structure, allowing the trolley body 100 to move along the length of the guide rail 200, thereby driving the cable to the corresponding position. The two ends of the guide rail 200 along its length are the first end 210 and the second end 220, respectively. One end of the traction wire rope 310 is fixed to the first end 210 of the guide rail 200 using a professional wire rope fixing component, such as a U-bolt clamp, and the other end is connected to the moving block 322. The fixing frame 321 is fixed to the second end 220 of the guide rail 200 by bolt connection or welding. The moving block 322 and the fixing frame 321 are movably connected. The traction wire rope 310 extends along the length of the guide rail 200, and the traction wire rope 310 is in a relatively loose state in the initial stage. The fixed frame 321 is set at the same height as the trolley body 100. The trolley body 100 is movably connected to the traction wire rope 310. As the trolley body 100 moves along the guide rail 200, it also moves along the traction wire rope 310. When the trolley body 100 falls off the guide rail 200, the traction wire rope 310 can act as a secondary slide for the trolley body 100, effectively preventing the trolley body 100 from falling. At this time, the trolley body 100 applies a force to the traction wire rope 310, which tightens the traction wire rope 310, thereby driving the moving block 322 to move on the fixed frame 321. In addition, a displacement detection module 324 is installed on the fixed frame 321. When the trolley body 100 falls off the guide rail 200, causing the traction wire rope 310 to drive the moving block 322 to move relative to the fixed frame 321, the displacement detection module 324 detects the displacement change of the moving block 322 and transmits the displacement signal to the control module 323. When the control module 323 receives the displacement signal, it determines that the trolley body 100 has fallen off the guide rail 200 and sends a signal to the alarm module 325 to control the alarm module 325 to issue an alarm message to remind the operator to repair or replace the trolley body 100 in time.

[0027] In actual operation, when the trolley body 100 is running normally on the guide rail 200, as it moves along the guide rail 200, the trolley body 100 also moves along the traction steel wire rope 310. At this time, the traction steel wire rope 310 is in a loose state, and the trolley body 100 applies a small force to the traction steel wire rope 310. The moving block 322 is stationary or moves slightly relative to the fixed frame 321. At this time, the slight displacement change is not included in the range of the displacement detection module 324 transmitting the displacement signal to the control module 323. However, when the trolley body 100 falls off the guide rail 200 due to some reason, such as overload causing damage to the connecting parts or vibration causing loosening of the connection, the trolley body 100 moves towards the traction steel wire rope 310. A large force is applied to the traction wire rope 310, thereby tightening the traction wire rope 310 and causing the moving block 322 to move on the fixed frame 321. This causes the displacement of the moving block 322 within the fixed frame 321 to exceed the normal preset range. The displacement detection module 324 detects this displacement change and sends a displacement signal to the control module 323. After receiving the displacement signal, the control module 323 confirms that the trolley body 100 has detached. Subsequently, the control module 323 quickly sends a control command to the alarm module 325. After receiving the command, the alarm module 325 immediately issues an alarm message to ensure that the staff can be informed of the detachment of the trolley body 100 as soon as possible and take appropriate measures in a timely manner.

[0028] In the above structure, by setting traction steel wire ropes 310 at both ends of the guide rail 200, the trolley body 100 is movably connected to the traction steel wire ropes 310, thereby enabling the traction steel wire ropes 310 to protect the trolley body 100 and prevent it from falling off, thus preventing the trolley from falling directly to the ground and damaging the cable in a short time, thereby achieving the anti-fall function of the trolley body 100. In addition, a moving block 322 is set at one end of the traction steel wire rope 310. Through the displacement detection module 324, the displacement change of the moving block 322 can be monitored in real time and accurately. Thus, the displacement signal of the moving block 322 can be detected at the moment when the trolley body 100 falls off, and it can be transmitted to the control module 323 in a timely manner. The alarm module 325 will also remind the operator of the fall situation, providing maintenance personnel with sufficient time for maintenance and recovery, and improving the timeliness and accuracy of fall detection.

[0029] In the specific structure of the fixed frame 321, the fixed frame 321 includes a fixed housing 3211, which is fixedly connected to the second end 220. The fixed housing 3211 is provided with a moving space 3212, and the moving block 322 is movably connected in the moving space 3212. The displacement detection module 324 includes a proximity switch, which is fixed on one end face of the moving space 3212 relative to the moving block 322.

[0030] In this embodiment, as Figure 2As shown, the fixed housing 3211 is a rectangular box structure with a hollow interior forming a moving space 3212. One side of the fixed housing 3211 is fixed to the second end 220 of the guide rail 200 by welding or high-strength bolts. The shape of the moving space 3212 matches the moving block 322, generally being a cuboid shape. Appropriate gaps are maintained between each side of the moving block 322 and the corresponding inner wall of the moving space 3212, ensuring that the free movement of the moving block 322 is not affected while also constraining its direction of movement, allowing it to move only along the length of the moving space 3212 within the fixed housing 3211. The displacement detection module 324 includes a proximity switch fixed to one end face of the moving space 3212 of the fixed housing 3211 opposite to the moving block 322. The detection surface of the proximity switch faces the moving path of the moving block 322. When the moving block 322 approaches the proximity switch to reach its set detection distance, the proximity switch rapidly generates an electrical signal change.

[0031] By installing the proximity switch on one end face of the moving space 3212 of the fixed housing 3211 relative to the moving block 322, the displacement change of the moving block 322 can be detected directly and accurately, which improves the accuracy of detecting the detachment of the trolley body 100 and reduces the possibility of misjudgment. In addition, the fixed housing 3211, as an integral structure, integrates the moving block 322 and the proximity switch together, making the entire fixed frame 321 compact.

[0032] In addition, the anti-detachment detection component includes a fixed rod 326, one end of which is fixedly connected to the traction steel wire rope 310. The fixed rod 326 can move within the moving space 3212. The moving block 322 is fixedly connected to the fixed rod 326, and the fixed rod 326 passes through the fixed box 3211 along its own axial direction.

[0033] In this implementation, such as Figure 3As shown, one end of the fixed rod 326 is fixedly connected to the traction wire rope 310. The fixed rod 326 passes through the moving block 322 and is fixedly connected to the moving block 322, so that the fixed rod 326 can drive the moving block 322 to move. A through hole that precisely matches the diameter of the fixed rod 326 is machined on the fixed box 3211 to ensure that the fixed rod 326 can smoothly pass through the fixed box 3211 along its own axis. The fixed rod 326 is connected to the traction wire rope 310. When the trolley body 100 moves the traction wire rope 310, the fixed rod 326 can move the moving block 322. Due to the rigid connection between the fixed rod 326 and the moving block 322, the displacement change of the moving block 322 can accurately reflect the displacement of the traction wire rope 310, thereby providing a precise detection signal for the proximity switch and improving the accuracy of detecting the trolley body 100 falling off. The fixed rod 326 penetrates the structure of the fixed housing 3211, providing a stable guide for the movement of the moving block 322. Moreover, when the device is subjected to external impact or vibration, it can distribute some of the force to the fixed housing 3211, enhancing the ability of the entire component to resist external interference and improving the overall stability and durability of the device.

[0034] Specifically, the anti-detachment detection component also includes an elastic element 327, which is sleeved on the fixed rod 326 and located between the side wall of the moving block 322 and the moving space 3212. When the moving block 322 moves toward the guide rail 200, the elastic element 327 is in an elastic contraction state.

[0035] In this embodiment, as Figure 3 As shown, the elastic element 327 is typically a spring structure. The elastic element 327 is sleeved on the fixed rod 326 and located between the side wall of the moving block 322 and the fixed box 3211. When the moving block 322 moves toward the guide rail 200 driven by the traction wire rope 310, the elastic element 327 is squeezed by the moving block 322 and enters an elastic contraction state. When the moving block 322 moves away from the guide rail 200, the elastic element 327 gradually returns to its original state, providing the moving block 322 with a reverse elastic force.

[0036] By setting the elastic element 327, a buffer protection is provided during the movement of the moving block 322, further protecting the moving block 322 and the fixed frame 321. In addition, the elastic element 327 makes the movement of the moving block 322 more stable during the movement process. Under normal working conditions, the elastic element 327 can cancel out the small displacement fluctuations of the moving block 322, making the signal received by the proximity switch more stable and accurate. When the trolley body 100 returns to normal working conditions, the elastic element 327 can push the moving block 322 back to the initial normal position through elastic force, realizing the self-resetting function of the entire anti-detachment detection component.

[0037] In addition, the movable block 322 is provided with a guide block 3221, and the fixed box 3211 is provided with a guide groove 3213 that is engaged with the guide block 3221. The guide groove 3213 extends along the moving direction of the movable block 322, and the guide block 3221 can move along the guide groove 3213.

[0038] In this embodiment, as Figure 3 As shown, the lower end face of the movable block 322 is provided with a guide block 3221. Correspondingly, a guide groove 3213 extending along its length is provided on the bottom wall of the movable space 3212 in the fixed housing 3211. The guide block 3221 and the guide groove 3213 are fitted together. When the movable block 322 moves within the fixed housing 3211, the guide block 3221 can move within the guide groove 3213. The guide block 3221 is cuboid in shape, and the guide groove 3213 matches the shape of the guide block 3221, being a rectangular groove, thus providing accurate guidance for the movement of the movable block 322. The cooperation between the guide block 3221 and the guide groove 3213 provides precise guidance for the movement of the movable block 322, making the movement of the movable block 322 within the fixed housing 3211 more stable and improving the stability of the entire anti-detachment detection assembly. At the same time, the stable movement trajectory allows the displacement detection module 324 to more accurately detect the displacement changes of the movable block 322.

[0039] In the mounting structure of the fixed housing 3211 and the guide rail 200, the fixed housing 3211 is provided with a mounting protrusion 3214 at one end near the guide rail 200. The cross-sectional area of ​​the mounting protrusion 3214 is larger than the cross-sectional area of ​​the fixed housing 3211. The mounting protrusion 3214 is fixedly connected to the second end 220 by bolts.

[0040] In this embodiment, as Figure 2 As shown, the mounting protrusion 3214 is a rectangular plate structure with a cross-sectional area larger than that of the fixed housing 3211, providing a larger installation contact area and enhancing the stability of the fixation. Specifically, multiple bolt holes are evenly distributed on the mounting protrusion 3214, and the second end 220 of the guide rail 200 also has corresponding bolt holes. During installation, bolts are passed through the bolt holes of the mounting protrusion 3214 and the second end 220 of the guide rail 200. Because the cross-sectional area of ​​the mounting protrusion 3214 is larger than that of the fixed housing 3211, its contact area with the second end 220 of the guide rail 200 is increased, making the connection between the fixed housing 3211 and the guide rail 200 more stable.

[0041] In the connection structure between the traction wire rope 310 and the trolley body 100, the device also includes a connector 400. The connector 400 includes a connecting plate 410 and a connecting ring 420. The connecting ring 420 is connected to the connecting plate 410, and the connecting plate 410 is detachably connected to the trolley body 100. The traction wire rope 310 passes through the connecting ring 420. Multiple connectors 400 are provided, and the multiple connectors 400 are evenly spaced along the length direction of the guide rail 200 on the trolley body 100.

[0042] In this embodiment, the connecting plate 410 is a rectangular plate structure with bolt holes at its four corners for detachable connection to the trolley body 100. The connecting ring 420 can be welded to the connecting plate 410 or integrally formed. The connecting ring 420 is circular, and its inner diameter is slightly larger than the outer diameter of the traction wire rope 310 to ensure that the traction wire rope 310 can be smoothly threaded through it. In addition, multiple connectors 400 are evenly spaced along the length of the guide rail 200 and connected to the trolley body 100.

[0043] In the above structure, the connector 400 is reliably connected to the trolley body 100 via a detachable connection to the connecting plate 410 and the traction wire rope 310 via the connecting ring 420. Multiple connectors 400 are evenly distributed on the trolley body 100, distributing the tension of the traction wire rope 310 evenly across all parts of the trolley body 100, preventing damage or detachment due to excessive localized stress. The detachable connection between the connecting plate 410 and the trolley body 100 facilitates the installation and removal of the connectors 400, thereby simplifying maintenance and replacement, improving work efficiency, and reducing maintenance costs.

[0044] Specifically, the alarm module 325 includes a buzzer 3251 and an alarm light 3252. In this embodiment, the alarm information includes the buzzer 3251 sounding and the alarm light flashing to alert the operator to the detachment of the trolley body 100.

[0045] Specifically, at least two anti-detachment mechanisms 300 are provided, with each anti-detachment mechanism 300 located on opposite sides of the trolley body 100. The two anti-detachment mechanisms 300 are symmetrically arranged on opposite sides of the trolley body 100 to ensure stable and effective anti-detachment protection for the trolley body 100. Each anti-detachment mechanism 300 includes a traction steel wire rope 310 and an anti-detachment detection component. The provision of two anti-detachment mechanisms 300 significantly improves the detection and prevention capabilities against detachment of the trolley body 100. Furthermore, the anti-detachment mechanisms 300 on both sides ensure a more balanced force distribution on the trolley body 100 during movement.

[0046] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
