Description

Technical Field

[0001] This utility model relates to the field of spool overhead crane conveying technology, and in particular to a spool overhead crane conveying device. Background Technology

[0002] Spools are widely used in industrial conveying, cable laying and heavy material handling. In the current technology, the hoisting and conveying of spools mostly rely on traditional cranes with simple supports.

[0003] Existing technologies have the following problems:

[0004] Extensive research revealed that existing patent documents still have some issues in practical use. The most obvious problem is that traditional structures are difficult to adapt to different sizes of spools. When replacing them, the brackets need to be reinstalled, which is inefficient and has low adaptability. Furthermore, the spools are prone to displacement or even falling off during transportation due to vibration or tilting, requiring frequent manual adjustments.

[0005] To address these shortcomings, we have proposed a spool overhead crane conveyor system. Utility Model Content

[0006] The purpose of this utility model is to provide a spool overhead crane conveying device to overcome the shortcomings of existing technologies.

[0014] 1. In this utility model, the spacing between the two moving blocks is adjusted to support stepless adjustment of the spool width, which can adapt to the needs of various industrial scenarios. Secondly, the guardrail and the limit seat form a double protection to avoid accidental deviation of the spool, reduce operational risks, and make transportation more stable and reliable.

[0025] Please refer to Figure 1-4 A spool overhead crane conveying device includes a frame 1, a guardrail 2 welded onto the frame 1, and a spool 4 disposed inside the guardrail 2. A limit seat 3 is slidably connected to the top surface of the frame 1, and both the limit seat 3 and the top surface of the frame 1 are provided with locking holes 5. A locking rod 6 is inserted into the locking hole 5, and a pull plate 7 is fixedly connected to one end of the locking rod 6. A spring 8 is sleeved between the bottom surface of the pull plate 7 and the top surface of the limit seat 3 on the outside of the locking rod 6. A guide groove 11 is provided inside the frame 1 along the axial direction of the spool 4, and a positive and negative threaded screw 12 is installed inside the guide groove 11. Moving blocks 13 are symmetrically arranged on the surface of the positive and negative threaded screw 12. A servo motor 10 is fixedly installed on the outer wall of the frame 1, and the output end of the servo motor 10 is fixedly connected to one end of the positive and negative threaded screw 12.

[0026] In use, based on the width of the spool 4, the servo motor 10 is started to drive the forward and reverse threaded screws 12 to rotate. Under the limiting and guiding action of the guide groove 11, the rotational motion can be converted into linear motion, and the two moving blocks 13 can be driven to move in opposite directions, so as to adjust the distance between the two moving blocks 13. This supports stepless adjustment of the width of the spool 4 and adapts to the needs of various industrial scenarios. Then, through the adjustable locking rod 6, which is inserted into the locking hole 5 at different positions, the spools 4 of different diameters can be quickly fixed to prevent the spools 4 from slipping during transportation and ensure the stability during transportation. Next, the spool 4 is hoisted on the frame 1 and positioned between the two moving blocks 13 and the two limit seats 3. The guardrail 2 and the limit seats 3 form a double protection to prevent the spool 4 from accidentally shifting, reduce the risk of operation, and make transportation more stable and reliable.

[0027] In this implementation plan: a number of self-locking casters 9 are fixedly installed on the bottom surface of the frame 1, and the casters 9 are distributed in pairs on both sides of the bottom surface of the frame 1.

[0028] Specifically, it improves the ease of movement of the entire frame 1, and when conveying larger spools 4, the frame 1 can be moved by traction equipment.

[0029] In this embodiment, multiple locking holes 5 are provided, and the multiple locking holes 5 are equidistantly distributed on the surface of the frame 1.

[0030] Specifically, it can be adapted to support and limit the movement of spools of different diameters, reducing the risk of rolling during movement.

[0031] In this embodiment: a control switch 14 is installed on the frame 1, and the control switch 14 is electrically connected to the servo motor 10 through a wire.

[0032] Specifically, these are common circuit connector structures, which will not be elaborated on here.

[0033] In this embodiment, two limit seats 3 are provided symmetrically about the spool 4, and the two limit seats 3 are arranged along the axial direction of the spool 4.

[0034] Specifically, the spool 4 is more securely fixed, and it is less likely to move unnecessarily during transportation.

[0035] In this embodiment, a protective pad is adhered to the surface of the movable block 13 near the spool 4.

[0036] Specifically, the spool 4 is more securely fixed, resulting in more stable conveying.

[0037] Working principle: During use, the distance between the two moving blocks 13 is adjusted according to the width of the spool 4, supporting stepless adjustment of the spool 4 width to adapt to various industrial scenarios. Then, through the adjustable locking rod 6, which is inserted into the locking hole 5 at different positions, spools 4 of different diameters can be quickly fixed to prevent slippage during transportation and ensure stability during transportation. Next, the spool 4 is hoisted on the frame 1 and positioned between the two moving blocks 13 and the two limit seats 3. The guardrail 2 and the limit seats 3 form double protection to prevent accidental displacement of the spool 4, reduce operational risks, and make transportation more stable and reliable.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
