[0006] The adjustable component includes a fixed box. Two sets of fixed boxes are fixedly connected to the front and rear ends of the first truss module. Two sets of connecting boxes are fixedly connected to the front and rear ends of the second truss module. A first gas spring is movably connected inside the fixed box. A first pull rod is movably connected to the front end of the first gas spring. A first elongated groove is formed at the end of the fixed box near the first pull rod. A first semi-circular disk is fixedly connected to the rear end of the first pull rod. A first semi-circular groove is fixedly connected to the middle position inside the fixed box. A second semi-circular groove is fixedly connected to the middle position inside the connecting box. A first arc groove is formed at the end of the first semi-circular groove near the first pull rod. A second gas spring is movably connected inside the connecting box. A second pull rod is movably connected to the rear end of the second gas spring. A second semi-circular disk is fixedly connected to the front end of the second pull rod. A second arc groove is formed at the middle position inside the connecting box. A second elongated groove is formed at the end of the second semi-circular groove near the second pull rod.

[0007] As a further technical solution of this utility model, the first pull rod can move left and right along the inside of the first long groove, and the first gas spring is elastic and retractable.

[0008] As a further technical solution of this utility model, the external shape and size of the first semi-circular disk are consistent with the internal shape and size of the first semi-circular groove, and the first semi-circular disk can rotate along the inside of the first semi-circular groove.

[0009] As a further technical solution of this utility model, the external shape and size of the second semi-circular disk are consistent with the internal shape and size of the second semi-circular groove, the second semi-circular disk can rotate along the inside of the second semi-circular groove, and the shape and size of the first semi-circular disk are consistent with those of the second semi-circular disk.

[0010] As a further technical solution of this utility model, a wind direction contactor is fixedly connected to the bottom of the first truss module, and multiple sets of wind cups are fixedly connected to the top of the wind direction contactor. A detection controller is provided on the right side of the wind direction contactor. The wind cups can rotate along the top of the wind direction contactor. The detection controller is electrically connected to the wind direction contactor and is fixedly connected to the first truss module.

[0011] As a further technical solution of this utility model, a protrusion is fixedly connected to the rear end of the first load-bearing beam, a connecting ring is provided at the bottom end of the protrusion, a fall arrester is fixedly connected to the bottom end of the connecting ring, the connecting ring is aligned with the vertical center line of the fall arrester, and the connecting ring is movably connected to the protrusion.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the adjustable cable hoist not only realizes the function of convenient adjustment and wind speed monitoring, but also realizes the function of safety protection;

[0013] (1) By providing a fixed box and a connecting box, during the installation of the first truss module and the second truss module, the second truss module can be directly connected to the first truss module. The connecting box is inserted into the fixed box. As the connecting box moves to the left, the second semicircular groove touches the first semicircular disk to the left and presses it down, causing the first semicircular disk to rotate counterclockwise along the inside of the first semicircular groove. At the same time, the first pull rod moves to the right along the first long groove and the first arc groove due to the stretching of the first gas spring. As the first semicircular disk gradually rotates, the first semicircular disk comes into contact with the second semicircular disk. The first semicircular disk synchronously drives the second semicircular disk to rotate counterclockwise. The rotation of the second semicircular disk stretches the second gas spring, and the second pull rod moves to the right along the second arc groove. The slot and the second long slot move to the left. As the fixing box and the connecting box fit together, the first semi-circular disk and the second semi-circular disk, the first semi-circular slot and the second semi-circular slot combine to form a circle. At this time, the first gas spring and the second gas spring rebound, pulling the first pull rod and the second pull rod clockwise respectively, so that the first semi-circular disk and the second semi-circular disk are locked in the first semi-circular slot and the second semi-circular slot, and the position is fixed. That is, the position of the fixing box and the connecting box is firmly fixed. At the same time, the position of the first truss module and the second truss module is fixed. By adding and removing the second truss module and the first truss module, the distance between the first crane and the second crane can be adjusted. The installation and addition process is simple and convenient for positioning adjustment when adding multiple sets, realizing convenient adjustment function.

[0014] (2) By setting up wind direction contactors and detection controllers, when using the cable crane, since it usually operates on the main cable at a height of 100 meters, it is directly exposed to the natural wind field, and the wind speed and wind direction change drastically. Relying on manual observation of wind speed changes is delayed and cannot trigger the protection mechanism in time. The wind speed can be monitored in real time through wind direction contactors and wind cups, and the data is transmitted to the detection controller. If the monitored wind speed exceeds the threshold, the detection controller will provide an audible and visual alarm to ensure safety and realize the wind speed monitoring function.

[0015] (3) By installing a fall arrestor, in order to improve the safety of high-altitude operations and reduce the risk of personnel injury, a fall arrestor was added behind the first load-bearing beam. When personnel are inspecting or carrying out construction, the bottom end of the fall arrestor can be connected to the safety rope on the operator's body. If a slip or fall occurs, the fall arrestor can slow down the user's descent speed and ensure that the operator can safely evacuate in case of an emergency, thus realizing the safety protection function.

[0024] Please see Figure 1-5The adjustable cable crane also includes an adjustment assembly, which includes a fixing box 7. Two sets of fixing boxes 7 are fixedly connected to the front and rear ends of the first truss module 3. Two sets of connecting boxes 8 are fixedly connected to the front and rear ends of the second truss module 4. A first gas spring 9 is movably connected inside the fixing box 7. A first pull rod 10 is movably connected to the front end of the first gas spring 9. A first long slot 11 is opened at the end of the fixing box 7 near the first pull rod 10. A first semi-circular disk 12 is fixedly connected to the rear end of the first pull rod 10. A first semi-circular groove 25 is fixedly connected to the middle position inside the fixing box 7. A second semi-circular groove 26 is fixedly connected to the middle position inside the connecting box 8. A first arc groove 13 is opened at the end of the first semi-circular groove 25 near the first pull rod 10. A second gas spring 14 is movably connected inside the connecting box 8. The rear end of the second gas spring 14 is movably connected to the second pull rod 15, and the front end of the second pull rod 15 is fixedly connected to the second semi-circular disk 16. A second arc groove 17 is opened in the middle of the inside of the connecting box 8. A second long groove 18 is opened at one end of the second semi-circular groove 26 near the second pull rod 15. The first pull rod 10 can move left and right along the inside of the first long groove 11. The first gas spring 9 is elastic and retractable. The external shape and size of the first semi-circular disk 12 are consistent with the internal shape and size of the first semi-circular groove 25. The first semi-circular disk 12 can rotate along the inside of the first semi-circular groove 25. The external shape and size of the second semi-circular disk 16 are consistent with the internal shape and size of the second semi-circular groove 26. The second semi-circular disk 16 can rotate along the inside of the second semi-circular groove 26. The first semi-circular disk 12 and the second semi-circular disk 16 are consistent in shape and size, which facilitates the adjustment of the spacing.

[0025] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, during use, when installing the first truss module 3 and the second truss module 4, the second truss module 4 can be directly connected to the first truss module 3. The connecting box 8 is inserted into the fixing box 7. As the connecting box 8 moves to the left, the second semicircular groove 26 contacts the first semicircular disk 12 and presses it down, causing the first semicircular disk 12 to rotate counterclockwise along the inside of the first semicircular groove 25. Simultaneously, the first pull rod 10 moves to the right along the first long groove 11 and the first arc groove 13 due to the tension of the first gas spring 9. As the first semicircular disk 12 gradually rotates, it contacts the second semicircular disk 16. The first semicircular disk 12 synchronously drives the second semicircular disk 16 to rotate counterclockwise. The rotation of the second semicircular disk 16 stretches the second gas spring 14, and the second pull rod 15 moves along the second arc groove 17 and... The second long slot 18 moves to the left. As the fixing box 7 and the connecting box 8 interlock, the first semicircular disk 12 and the second semicircular disk 16, the first semicircular slot 25 and the second semicircular slot 26 finally combine to form a circle. At this time, the first gas spring 9 and the second gas spring 14 rebound, pulling the first pull rod 10 and the second pull rod 15 clockwise respectively, so that the first semicircular disk 12 and the second semicircular disk 16 are locked in the first semicircular slot 25 and the second semicircular slot 26, and their positions are fixed. That is, the positions of the fixing box 7 and the connecting box 8 are firmly fixed. At the same time, the positions of the first truss module 3 and the second truss module 4 are fixed. By adding and removing the second truss module 4 and the first truss module 3, the distance between the first crane 1 and the second crane 6 can be adjusted. The installation and addition process is simple, and it is convenient for positioning adjustment when adding multiple sets, and it is easy to adjust the distance.

[0026] The bottom of the first truss module 3 is fixedly connected to a wind direction contactor 19. Multiple wind cups 20 are fixedly connected to the top of the wind direction contactor 19. A detection controller 21 is set on the right side of the wind direction contactor 19. The wind cups 20 can rotate along the top of the wind direction contactor 19. The detection controller 21 is electrically connected to the wind direction contactor 19 and is fixedly connected to the first truss module 3 for convenient speed measurement.

[0027] Specifically, such as Figure 1 As shown, during use, since the cross-cable crane usually operates on the main cable at a height of hundreds of meters, it is directly exposed to the natural wind field, and the wind speed and direction change drastically. Relying on manual observation of wind speed changes is delayed and cannot trigger the protection mechanism in time. The wind speed can be monitored in real time through the wind direction contactor 19 and the wind cup 20, and the data is transmitted to the detection controller 21. If the monitored wind speed exceeds the threshold, the detection controller 21 will issue an audible and visual alarm to ensure safety and facilitate speed measurement.

[0028] The rear end of the first load-bearing beam 2 is fixedly connected to a protrusion 22. A connecting ring 23 is provided at the bottom end of the protrusion 22. A fall arrester 24 is fixedly connected at the bottom end of the connecting ring 23. The vertical center line of the connecting ring 23 and the fall arrester 24 are aligned. The connecting ring 23 and the protrusion 22 are movably connected to ensure safety.

[0029] Specifically, such as Figure 1 and Figure 5 As shown, in order to improve the safety of high-altitude operations and reduce the risk of personal injury, a fall arrestor 24 is added after the first load-bearing beam 2. When personnel are inspecting or carrying out construction, the bottom end of the fall arrestor 24 can be connected to the safety rope on the operator's body. In the event of slipping or falling, the fall arrestor 24 can slow down the user's descent speed, ensuring that the operator can safely evacuate in case of an emergency and protecting safety.

[0030] Working Principle: In use, during the installation of the first truss module 3 and the second truss module 4, the second truss module 4 can be directly connected to the first truss module 3. The connecting box 8 is inserted into the fixing box 7. As the connecting box 8 moves to the left, the second semicircular groove 26 contacts the first semicircular disk 12 and presses it down, causing the first semicircular disk 12 to rotate counterclockwise along the inside of the first semicircular groove 25. Simultaneously, the first pull rod 10 moves to the right along the first long groove 11 and the first arc groove 13 due to the stretching of the first gas spring 9. As the first semicircular disk 12 gradually rotates... The first semi-circular disk 12 contacts the second semi-circular disk 16. The first semi-circular disk 12 synchronously drives the second semi-circular disk 16 to rotate counterclockwise. The rotation of the second semi-circular disk 16 stretches the second gas spring 14. The second pull rod 15 moves to the left along the second arc groove 17 and the second long groove 18. As the fixing box 7 and the connecting box 8 interlock, the first semi-circular disk 12 and the second semi-circular disk 16, the first semi-circular groove 25 and the second semi-circular groove 26 finally combine to form a circle. At this time, the first gas spring 9 and the second gas spring 14 rebound, respectively pulling the first pull rod 10 and the second pull rod 15 to move clockwise, causing the first semi-circular disk 12 to... The second semicircular disk 16 is fixed in the first semicircular groove 25 and the second semicircular groove 26, thus the positions of the fixing box 7 and the connecting box 8 are firmly fixed. At the same time, the positions of the first truss module 3 and the second truss module 4 are fixed. By adding or removing the second truss module 4 and the first truss module 3, the distance between the first crane 1 and the second crane 6 can be adjusted. The installation and addition process is simple and convenient for positioning adjustment when adding multiple sets. During use, because the cross-cable crane usually operates on the main cable at a height of hundreds of meters, it is directly exposed to the natural wind field, and the wind speed and direction change drastically. Relying on manual observation of wind speed changes is delayed and cannot keep up with the actual situation. The system triggers a protection mechanism that monitors wind speed in real time via the wind direction contactor 19 and the wind cup 20, transmitting the data to the detection controller 21. If the monitored wind speed exceeds the threshold, the detection controller 21 will issue an audible and visual alarm to ensure safety. To improve the safety of high-altitude operations and reduce the risk of personal injury, a fall arrestor 24 is added behind the first load-bearing beam 2. During maintenance and construction, the bottom of the fall arrestor 24 can be connected to the safety rope on the operator. In case of slipping or falling, the fall arrestor 24 can slow down the user's descent speed, ensuring that the operator can evacuate safely in case of an emergency.
