Description

Technical Field

[0001] This utility model relates to a crane anti-sway control system, belonging to the field of crane technology. Background Technology

[0002] In modern industrial production, cranes are an indispensable lifting equipment, mainly used for lifting and moving large materials or heavy objects. They are widely used in port loading and unloading, construction sites, factory workshops and other scenarios. During the lifting process, ropes are often used to hold the heavy objects below. When the crane lifts and moves the heavy objects, the heavy objects below will sway, especially during the initial start and stop. If the swaying amplitude of the heavy objects below is too large, it will cause safety hazards and lead to damage to materials or equipment.

[0003] For example, Chinese utility model patent application CN202223083970.1 discloses a mechanical anti-sway device for a crane. It includes two parallel I-beam rails, each with a hoist-type inverted trolley slidably mounted on it. The two hoist-type inverted trolleys are connected by a fixed frame. Upper guide columns are located near both ends of the fixed frame, and these upper guide columns are slidably connected to lower guide columns. The bottom end of the lower guide column is fixedly connected to the lifting device. The crane in this utility model consists of two electric single-girder cranes. Each crane's main beam I-beam rail is equipped with a hoist-type inverted trolley, and the two trolleys are connected by a fixed frame. The fixed frame and the lifting device are guided by a sliding connection between the upper and lower guide columns, ensuring that the lifting device always moves vertically up and down without swaying.

[0004] The aforementioned document uses lower and upper guide columns to limit the position of the lifting equipment below, thereby preventing excessive swaying. The position of the lower guide column is limited by guide wheels. Although this method limits the swaying of the lifting equipment, the structure is fixed below and will continuously impact the lower and upper guide columns when lifting heavy objects, resulting in poor structural stability. Furthermore, the lower and upper guide columns need to be adapted to the lifting height, which reduces the flexibility of use. Utility Model Content

When lifting heavy objects, it reduces the sway amplitude of the load-bearing rope. When swaying occurs, the drive mechanism can move the buffer component and the locking mechanism to the corresponding position, and then control the telescopic rod to slow down the swaying changes of the load-bearing rope.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a crane anti-sway control system, including a track ring, which is located outside the load-bearing rope and needs to be fixed on a slide rail trolley or a boom in practical applications, and needs to follow it during use.

[0010] Preferably, in order to facilitate the stability of the component structure during movement, a reinforcing component is fixed to the bottom of the support plate, and a snap-fit ​​ring is provided at the bottom end of the reinforcing component. The snap-fit ​​ring extends to the bottom of the drive motor and is sleeved on the output shaft of the drive motor.

[0011] Preferably, in order to obtain better bottom support when the locking telescopic rod moves, a support block is fixed on the edge plate, a buffer spring is fixed on the side wall of the edge plate, and a middle plate is fixed to one end of the buffer spring.

When swaying occurs, the drive mechanism can move the buffer component and the locking mechanism to the corresponding position, and then the swaying change of the load-bearing rope is slowed down by controlling the telescopic rod.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5As shown, a crane anti-sway control system includes a track ring 1, which is located outside the load-bearing rope. In practical applications, it needs to be fixed to a slide rail trolley or a boom and needs to follow it during use. A track groove is formed on the upper surface of the track ring 1, and a movable seat 2 is slidably engaged in the track groove. A control telescopic rod 201 is fixed on the movable seat 2. A buffer assembly 3 is fixed to one end of the control telescopic rod 201. A locking mechanism 4 is installed on the buffer assembly 3. The buffer assembly 3 includes a movable plate 301. Edge plates 302 are fixed on both sides above the movable plate 301. Wing plates 303 are fixed on both sides of the edge plates 302 near the load-bearing rope. One end of the control telescopic rod 201 is fixed to the wing plate 303. A limit protrusion 304 is fixed to the bottom of the movable plate 301. A bearing plate 202 is fixed on the side wall of the movable seat 2. One end of the bearing plate 202 extends to the bottom of the movable plate 301, which facilitates the stabilization of the position of the movable plate 301 during movement.

[0023] like Figures 3-5 As shown, a drive mechanism 5 is installed at the bottom of the support plate 202. The drive mechanism 5 includes a drive motor 501 fixed to the bottom of the moving plate 301. A drive gear 502 is fixed on the output shaft of the drive motor 501, which facilitates the movement of the control telescopic rod 201 to a suitable position. A bottom ring plate 101 is fixed at the bottom of the track ring 1. An internal tooth is fixed on the inner wall of the bottom ring plate 101. The drive gear 502 meshes with the inner wall of the bottom ring plate 101, which facilitates the movement of the control telescopic rod 201. A support block 305 is fixed on the edge plate 302. A buffer spring 306 is fixed on the side wall of the edge plate 302. A middle plate 307 is fixed to one end of the buffer spring 306, which provides better bottom support when the telescopic rod 401 is locked in place.

[0024] like Figure 5 As shown, a reinforcing component 6 is fixed to the bottom of the bearing plate 202. The bottom end of the reinforcing component 6 is provided with a snap ring 601. The snap ring 601 extends to the bottom of the drive motor 501 and is sleeved on the output shaft of the drive motor 501. This facilitates the stabilization of the component structure during movement.

[0025] like Figure 2As shown, the locking mechanism 4 includes a locking telescopic rod 401, which is located above the wing plate 303. The top of the intermediate plate 307 is fixed to the locking telescopic rod 401. A limit block 402 is fixed to one end of the locking telescopic rod 401. An arc-shaped notch is provided on the side wall of the limit block 402, which facilitates the application of control force to the load-bearing rope. A pull-back arm 403 is fixed to the side wall of the locking telescopic rod 401. One end of the pull-back arm 403 extends to the opposite side of the limit block 402. A pressure detector is provided in the arc-shaped notch. A space is left between the arc-shaped notch and one end of the pull-back arm 403 for the load-bearing rope to pass through, which facilitates the restriction of the position of the load-bearing rope.

[0026] This control system is mainly used to reduce the swaying amplitude of the load-bearing rope when lifting heavy objects. When swaying occurs, the drive mechanism 5 can move the buffer component 3 and the locking mechanism 4 to the corresponding positions, and then the swaying change of the load-bearing rope is slowed down by controlling the telescopic rod 201. In use, the telescopic rod 201 plays the main control role, controlling the movement of the buffer component 3 by its own extension and retraction, and then applying the control force to the load-bearing rope through the locking mechanism 4.

[0027] When in use, if the hoisted load only moves linearly between two points, the positional range of the drive mechanism 5 is small. However, for some load-bearing ropes with complex swing trajectories, a ring of pressure detectors can be added around the load-bearing rope to promptly determine its swing position. Alternatively, multiple control systems can be installed outside the load-bearing rope to jointly control it. When locking the telescopic rod 401, the limit block 402 needs to be brought close to the load-bearing rope. Then, the buffer assembly 3 is slowly pushed or pulled back by controlling the telescopic rod 201. The load-bearing rope is then pushed. At this time, the buffer spring 306 provides a certain buffering effect to prevent the rope from swinging excessively.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
