Description

Technical Field

[0001] This utility model relates to the technical field of anti-tangling structure for steel wire rope drums of stacker cranes, specifically an anti-tangling structure for steel wire rope drums of stacker cranes. Background Technology

[0002] Stacker cranes, as the core handling equipment in modern automated warehouses, play a vital role in the production and logistics systems of emerging industries such as lithium-ion batteries. They are responsible for the high-speed and precise automatic storage and retrieval of raw materials, semi-finished products and finished products such as battery cells between dense storage racks. Their lifting mechanism usually achieves the vertical movement of the loading platform by driving a drum to wind up and unwind a steel wire rope through a motor.

[0003] During the descent of the stacker crane's lifting drum, when the loading platform reaches its lowest position or stops for other reasons, the drum continues to rotate. This causes the wire rope wound on the drum to slack, become tangled, and detach from the drum's spiral groove. It may even become entangled in the gap between the motor and the side of the drum. In severe cases, this can damage the seal on the motor shaft, leading to oil leaks from the motor and damage to the wire rope, thus preventing the stacker crane from operating normally. To address this, we propose a structure to prevent the wire rope from becoming tangled on the stacker crane drum. Utility Model Content

[0004] The purpose of this utility model is to provide a structure to prevent the steel wire rope of a stacker crane drum from becoming tangled, so as to solve the problem mentioned in the background art that when the loading platform is at its lowest position or stops for other reasons, the stacker crane lifting drum is still running, causing the steel wire rope wound on the drum to become loose, tangled and detached from the drum's spiral groove.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stacker crane drum wire rope anti-tangling structure, comprising: a support frame, a drum lifting motor above the support frame, a drum outside the drum lifting motor, a drum protective cover outside the drum, a fixing module on the drum protective cover, a movable gripper and an extension arm inside the fixing module, the fixing module controls the extension arm to extend to a preset length so that the movable gripper clamps the edge of the drum protective cover, an adjustment module on the fixing module, a limit stop inside the adjustment module, the adjustment module controls the limit stop to approach the drum to constrain the movement range of the wire rope.

[0006] The fixing module includes a fixing claw that fits onto the roll protective cover. The fixing claw is fixedly connected to a fixing seat. A screw hole is opened on one side of the fixing seat. A stud is threaded into the screw hole. A movable claw is fixedly connected to the end of the stud. An extension arm is fixedly connected to the fixing seat. A fixing hole is opened on the extension arm. A fixing post is threaded into the fixing hole. A mounting plate is threaded into the fixing post.

[0007] The adjustment module includes a limiting post fixedly connected to the mounting plate. The limiting post is slidably connected to the limiting block. A reserved groove is provided on the limiting block. The limiting post moves within the range of the reserved groove. An adjustment hole is provided on the outer side of the mounting plate. An adjustment push rod is threadedly connected to the adjustment hole. The adjustment push rod is fixedly connected to the limiting block.

[0008] The support frame has reinforcing ribs along its edges.

[0009] The fixed gripper and the movable gripper are equipped with anti-slip pads on their inner sides.

[0010] The adjusting push rod has a rubber sleeve at its end.

[0011] This utility model has at least the following beneficial effects: In use, this utility model, through the coordinated action of the clamps and the extension arm, can quickly and securely fit and lock onto the protective covers of drums of different specifications. Then, through the precise control of the adjustment module, the gap between the limit block and the drum can be accurately and conveniently adjusted to form a constant and effective constraint channel smaller than the diameter of the wire rope, preventing the wire rope from detaching from the spiral rope groove in a slack state. This solves the problems of equipment jamming, wire rope wear, and component damage caused by tangled ropes, improving the working reliability and safety of the stacker crane lifting mechanism. Its modular design has excellent versatility and adaptability, reducing the maintenance frequency and cost of the equipment. Attached Figure Description

[0014] 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.

[0015] Example 1 Please see Figures 1 to 4 This utility model provides a technical solution: a stacker crane drum wire rope anti-tangling structure, comprising: a support 1, a drum lifting motor 2 mounted above the support 1, a drum 3 mounted outside the drum lifting motor 2, and a drum protective cover 4 mounted outside the drum 3. During operation, the support 1 of the entire device is securely connected to the main structure of the stacker crane. The drum lifting motor 2 drives the drum 3 to rotate, winding and unwinding the wire rope. The drum protective cover 4 provides basic safety protection. A fixing module 5 located on the drum protective cover 4 works in coordination with a movable gripper 55 and an extension arm 56. The fixing module 5 first controls the extension arm 56. Extend to a length suitable for crossing the edge of the drum protective cover 4, and then drive the movable gripper 55 to move, engage with the other edge of the drum protective cover 4 and clamp it, thereby completing the final fixation of the entire fixing module 5. Based on this fixation, the adjustment module 6 set on the fixing module 5 begins to perform its core function. The limit stop 62 inside the adjustment module 6 moves under its control, precisely approaching the outer edge of the drum 3, thereby forming a narrow constraint channel. When the wire rope may jump due to slack, this channel can effectively constrain its range of motion and prevent it from falling off the spiral groove on the drum 3.

[0016] The fixing module 5 includes a fixing jaw 51 that fits onto the drum protective cover 4. The fixing jaw 51 is fixedly connected to a fixing base 52. A screw hole 53 is provided on one side of the fixing base 52, and a stud 54 is threaded into the screw hole 53. A movable jaw 55 is fixedly connected to the end of the stud 54. An extension arm 56 is fixedly connected to the fixing base 52. A fixing hole 57 is provided on the extension arm 56, and a fixing post 58 is threaded into the fixing hole 57. A mounting plate 59 is threaded into the fixing post 58. During installation, the fixing jaw 51 is first stably fitted onto one edge of the drum protective cover 4, and then the stud 54 is manually rotated. Since the stud 54 and the screw hole 53 on the fixed base 52 are threadedly connected, the rotational motion is converted into linear motion, thereby pushing the movable jaw 55 at the end to move closer to the fixed jaw 51 until the two firmly clamp the edge of the drum protective cover 4. According to the needs of the on-site installation space, the extension length of the extension arm 56 can be adjusted so that the mounting plate 59 at its end reaches an ideal operating position. Then, by screwing the fixed post 58 into the fixed hole 57 on the extension arm 56 and the corresponding threaded hole of the mounting plate 59, the mounting plate 59 is firmly fixed, providing a stable foundation for the subsequent installation of the adjustment module 6.

[0017] The adjustment module 6 includes a limiting post 61 fixedly connected to the mounting plate 59. The limiting post 61 is slidably connected to a limiting block 62. A reserved groove 63 is provided on the limiting block 62, and the limiting post 61 moves within the range of the reserved groove 63. An adjustment hole 64 is provided on the outer side of the mounting plate 59. An adjustment push rod 65 is threadedly connected to the adjustment hole 64. The adjustment push rod 65 is fixedly connected to the limiting block 62. When it is necessary to adjust the gap between the limiting block 62 and the wire rope on the drum 3, the operator rotates the adjustment push rod 65. Since the adjustment push rod 65 is threadedly connected to the adjustment hole 64 on the mounting plate 59, its rotation will be converted into its own axial movement. The push rod 65 and the limit block 62 are fixedly connected. Therefore, adjusting the push rod 65 will directly push or pull the limit block 62 to slide along the limit post 61. During this process, the reserved groove 63 on the limit block 62 provides precise guidance and displacement space for the movement of the limit block 62. At the same time, the cooperation between the limit post 61 and the reserved groove 63 ensures the smoothness and straightness of the movement of the limit block 62 and prevents deflection. Through this operation, the front and rear positions of the limit block 62 can be precisely controlled to maintain an optimal anti-tangling gap between it and the wire rope that is smaller than the diameter of the wire rope. After the adjustment is completed, the entire device can enter the working state.

[0018] Example 2 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the support 1 may be provided with reinforcing ribs 7 on its edge to enhance the overall structural strength. The inner sides of the fixed gripper 51 and the movable gripper 55 may be provided with anti-slip pads 8 to increase the gripping friction and stability. The end of the adjusting push rod 65 may be provided with a rubber sleeve 9 to facilitate operation and play an anti-slip role.
