Description

Technical Field

[0001] This invention relates to the field of drum technology, and more specifically to a drum that facilitates the assembly and disassembly of wire ropes. Background Technology

[0002] Port machinery typically uses wire ropes wound on drums. The forward and reverse rotation of the drum controls the unwinding and rewinding of the wire rope, enabling the equipment to lift, open, close, run, and tilt. As the primary component enabling these functions, the wire rope is a consumable part and requires replacement after a period of use. Typically, the wire ropes used for these operations are hundreds of meters long, have a large diameter, and are heavy, making their installation and replacement a complex and cumbersome process.

[0003] When dismantling an old wire rope, a temporary wire rope (or traction rope) is temporarily tied or tightened at the end of the old wire rope as needed. This temporary wire rope helps the old wire rope to be completely wound onto the wire rope reel. As the drum rotates, the old wire rope is wound and arranged onto the wire rope reel via the temporary wire rope. When reinstalling a new wire rope, a temporary wire rope (or traction rope) needs to be temporarily tied or tightened at the end of the new wire rope. This temporary wire rope is fixed to the drum, and as the drum rotates, the new wire rope is wound onto the drum via the temporary wire rope. However, dismantling old wire ropes and reinstalling new wire ropes requires the temporary calculation and preparation of the temporary wire rope, which is cumbersome and inefficient. Therefore, a reel design that facilitates the dismantling and installation of wire ropes is urgently needed to solve these problems. Summary of the Invention

[0004] To address the technical problems of needing to temporarily calculate and prepare temporary wire ropes when dismantling old wire ropes and reinstalling new ones, which is cumbersome and inefficient, this invention provides a drum that facilitates the dismantling and installation of wire ropes. It features an auxiliary wire rope and three rope clamps (first, second, and third). The auxiliary wire rope is wound around the drum body, eliminating the need for temporary calculations and preparation, reducing auxiliary work and tools, simplifying the installation and dismantling process of the working wire rope, and lowering construction difficulty and costs. The first rope clamp secures the auxiliary wire rope to prevent it from falling off, while the second and third rope clamps provide double protection for the working wire rope, preventing it from slipping off.

[0005] This invention provides a reel for easy assembly and disassembly of wire rope, comprising a reel body, an auxiliary wire rope, a working wire rope, and a fixing mechanism. Both ends of the reel body are fixedly provided with baffles. A fixing structure is fixedly provided on the left side of the reel body, and a rope groove is provided on the right side of the reel body. The fixing mechanism includes a first rope clamp, a second rope clamp, and a third rope clamp. The first rope clamp is fixedly provided on the baffle located on the left side. The second rope clamp is detachably provided on the fixing structure. The third rope clamp is detachably provided on the reel body and is located between the fixing structure and the rope groove. The ends of the auxiliary wire rope and the working wire rope are tied or untied. After being tied, the left ends of the auxiliary and working wire ropes are wound around the left side of the reel body. The first rope clamp fixes the auxiliary wire rope, the second rope clamp fixes the left end of the working wire rope, and the right end of the working wire rope passes through the fixing structure, is fixed by the third rope clamp, and then wound around the rope groove.

[0006] Furthermore, a boss is provided on the left side of the drum body, and the fixing structure is fixedly installed on the right side of the boss. The left ends of the tightened auxiliary wire rope and working wire rope are wound around the boss. The boss facilitates the winding of the left ends of the auxiliary wire rope and working wire rope.

[0007] Furthermore, multiple first rope clamps are provided, each first rope clamp including a first fixed cylinder and a first fixed block. The first fixed cylinder is fixedly mounted on the first fixed block, and the first fixed block is provided with a first slot. A first screw hole is provided on the baffle on the left side. A first bolt passes through the first fixed cylinder and is threaded into the first screw hole. The first slot faces the baffle on the left side, and the auxiliary wire rope is clamped between the first slot and the baffle on the left side. After the first bolt passes through the first fixed cylinder and is threaded into the first screw hole, the first rope clamp is fixed to the baffle on the left side, and the auxiliary wire rope is fixed between the first slot and the baffle on the left side.

[0008] Furthermore, the fixing structure includes three arc-shaped fixing plates, which are equally spaced and fixedly disposed on the right side of the boss. The three arc-shaped fixing plates are arranged in a ring, and a gap is formed between two adjacent arc-shaped fixing plates. The second rope clamp is fixedly disposed on any one of the arc-shaped fixing plates. The right end of the working wire rope passes through one of the gaps near the second rope clamp, is fixed by the third rope clamp, and is then wound around the rope groove.

[0009] Furthermore, multiple second rope clamps are provided, each including a second fixing cylinder and a second fixing block. The second fixing cylinder is fixedly mounted on the second fixing block, and the second fixing block is provided with a second slot. Each arc-shaped fixing piece is provided with multiple second screw holes. A second bolt passes through the second fixing cylinder and the second screw holes and is fixedly connected to a fastening nut. The second slot faces one of the arc-shaped fixing pieces, and the left end of the working wire rope is clamped between the second slot and one of the arc-shaped fixing pieces. After the second bolt passes through the second fixing cylinder and the second screw holes, it is fixedly connected to the fastening nut, thus fixing the second rope clamp to the arc-shaped fixing piece, and fixing the left end of the working wire rope between the second slot and the arc-shaped fixing piece.

[0010] Furthermore, the right portion of the drum body is divided into a first region and a second region, the third rope clamp is located in the first region, and the rope groove is located in the second region.

[0011] Furthermore, multiple third rope clamps are provided, each including a third fixing block. Each third fixing block has a central screw hole and two third slots located on either side of the central screw hole. A third screw hole is provided on the right side of the drum body. The screw passes through the central screw hole and the third screw hole and is fixed to the right side of the drum body by a clamping nut. The two third slots face the outer wall of the right side of the drum body. The right end of the working wire rope is clamped between the two third slots and the right side of the drum body. The screw passes through the central screw hole and the third screw hole and is fixed to the right side of the drum body by a clamping nut. The third rope clamps are thus fixed to the right side of the drum body, and the right end of the working wire rope is fixed between the third slots and the right side of the drum body.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The drum of this invention is equipped with an auxiliary steel wire rope and a first rope clamp, a second rope clamp, and a third rope clamp. The auxiliary steel wire rope is wound around the main body of the drum, eliminating the need for temporary calculation and preparation of temporary steel wire ropes, avoiding auxiliary work and tools, simplifying the installation and disassembly process of the working steel wire rope, and reducing construction difficulty and cost. The first rope clamp fixes the auxiliary steel wire rope to prevent it from falling off, while the second and third rope clamps provide double protection for the working steel wire rope to prevent it from falling off.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1-9As shown, a reel for easy assembly and disassembly of a wire rope includes a reel body 1, an auxiliary wire rope 2, a working wire rope 3, and a fixing mechanism. Both ends of the reel body 1 are fixedly provided with baffles 11. A fixing structure 4 is fixedly provided on the left side of the reel body 1, and a rope groove 12 is provided on the right side of the reel body 1. The fixing mechanism includes a first rope clamp 5, a second rope clamp 6, and a third rope clamp 7. The first rope clamp 5 is fixedly provided on the baffle 11 located on the left side. The second rope clamp 6 is detachably provided on the fixing structure 4 and is located between the left baffle 11 and the fixing structure 4. The third rope clamp 7... The auxiliary wire rope 2 and the working wire rope 3 are detachably mounted on the drum body 1, with the third rope clamp 7 located between the fixed structure 4 and the rope groove 12. The rope ends of the auxiliary wire rope 2 and the working wire rope 3 are tied or loosened. After being tied, the left ends of the auxiliary wire rope 2 and the working wire rope 3 are wound around the left side of the drum body 1. The left ends of the auxiliary wire rope 2 and the working wire rope 3 are located between the left side baffle 11 and the fixed structure 4. The first rope clamp 5 fixes the auxiliary wire rope 2, and the second rope clamp 6 fixes the left end of the working wire rope 3. The right end of the working wire rope 3 passes through the fixed structure 4, is fixed by the third rope clamp 7, and then wound around the rope groove 12.

[0027] The working wire rope 3 enables the equipment to lift, open, close, run, tilt, and lower. Compared to the working wire rope 3, the auxiliary wire rope 2 has a smaller size and specifications. Generally, the working wire rope 3 has a larger diameter, while the auxiliary wire rope 2 has a smaller diameter.

[0028] The installation process of the working wire rope 3 on the drum body 1 is as follows: The rope ends of the auxiliary wire rope 2 and the working wire rope 3 are fixed together using shackles or aluminum alloy steel connectors (i.e., the left ends of the auxiliary wire rope 2 and the working wire rope 3 are connected and fixed to form a single wire rope). After being tightened, the left ends of the auxiliary wire rope 2 and the working wire rope 3 are wound around the left side of the drum body 1. The first rope clamp 5 fixes the auxiliary wire rope 2 to keep it stationary. The second rope clamp 6 is fixed to the fixed structure 4 and fixes the left end of the working wire rope 3 to keep it stationary. The right end of the working wire rope 3 passes through the fixed structure 4 and is fixed by the third rope clamp 7 before being wound around the rope groove 12. The third rope clamp 7 fixes the right end of the working wire rope 3 to keep it stationary. The above installation process can be repeated to install new working wire ropes 3. When the drum body 1 rotates, only the part of the working wire rope 3 wound around the rope groove 12 is wound up and down (to meet the needs of equipment lifting, opening and closing, running, tilting up and down). The setting of the rope groove 12 not only enables the working wire rope 3 of the first layer to be arranged neatly, which is conducive to the neat arrangement of the working wire rope 3 of each subsequent layer, but also effectively reduces the wear of the working wire rope 3.

[0029] The working wire rope 3 is fixed using a double-clamping structure, namely, a second rope clamp 6 and a third rope clamp 7. The portion of the working wire rope 3 wound around the left side of the drum body 1 is fixed with the second rope clamp 6, while the portion of the working wire rope 3 located between the fixing structure 4 and the rope groove 12 is fixed with the third rope clamp 7. The second rope clamp 6 and the third rope clamp 7 provide double protection for the working wire rope 3, preventing it from falling off.

[0030] The disassembly process of the working wire rope 3 on the drum body 1 is as follows: The operator manually loosens the third rope clamp 7, the drum body 1 rotates, and the right end of the working wire rope 3 is lowered. As it lowers, the second rope clamp 6 is loosened, and the left end of the working wire rope 3 and part of the auxiliary wire rope 2 are lowered. When the tightened auxiliary wire rope 2 and the left end of the working wire rope 3 (the connection point between the auxiliary wire rope 2 and the working wire rope 3) are lowered to a position that the operator can reach, the operator manually removes the shackle or aluminum alloy steel connector, thus loosening the rope ends of the auxiliary wire rope 2 and the working wire rope 3. A wire rope reel is set up on the working ground. The wire rope reel works synchronously with the drum body 1, winding and organizing the working wire rope 3 onto it. The above disassembly process is repeated to remove the old working wire rope 3.

[0031] When installing and dismantling the working wire rope 3, no additional drive is required. The existing drive unit of the equipment can be used to rotate the drum body 1, thus completing the dismantling and installation of the working wire rope 3. Previously, the wire rope reel was installed on a high-altitude platform, requiring a crane to hoist the entire reel to the ground. Using a crane was costly and posed safety risks. Installing the wire rope reel on the working ground effectively solves these problems.

[0032] In this embodiment, the drum is equipped with an auxiliary wire rope 2, a first rope clamp 5, a second rope clamp 6, and a third rope clamp 7. The auxiliary wire rope 2 is wound around the drum body 1, eliminating the need for temporary calculation and preparation of temporary wire ropes, avoiding auxiliary work and tools, simplifying the installation and disassembly process of the working wire rope 3, and reducing construction difficulty and cost. The first rope clamp 5 fixes the auxiliary wire rope 2 to prevent it from falling off, while the second rope clamp 6 and the third rope clamp 7 provide double protection for the working wire rope 3 to prevent it from falling off.

[0033] In one possible implementation, a boss 13 is provided on the left side of the drum body 1, and the fixing structure 4 is fixedly disposed on the right side of the boss 13. The left ends of the tightened auxiliary wire rope 2 and working wire rope 3 are wound around the boss 13. The boss 13 facilitates the winding of the left ends of the auxiliary wire rope 2 and working wire rope 3. Preferably, the surface of the boss 13 is a smooth surface, which reduces the difficulty of manufacturing the drum body 1 and the production cost.

[0034] In one possible implementation, multiple first rope clamps 5 (only one is shown for illustration in this embodiment) are provided. Each first rope clamp 5 includes a first fixing cylinder 51 and a first fixing block 52. The first fixing cylinder 51 is fixedly mounted on the first fixing block 52. The first fixing block 52 is provided with a first slot 521. The baffle 11 on the left side is provided with a first screw hole. A first bolt 53 passes through the first fixing cylinder 51 and is threadedly connected to the first screw hole. The first slot 521 faces the baffle 11 on the left side. The auxiliary wire rope 2 is clamped between the first slot 521 and the baffle 11 on the left side. Preferably, six first rope clamps 5 are provided, and the six first rope clamps 5 are arranged in a ring. After the first bolt 53 passes through the first fixing cylinder 51, it is threadedly connected to the first screw hole. The first rope clamps 5 are fixed to the baffle 11 on the left side, and the auxiliary wire rope 2 is fixed between the first slot 521 and the baffle 11 on the left side. When disassembling the working wire rope 3, the auxiliary wire rope 2 will not be fully lowered, and the first rope clamps 5 do not need to be loosened.

[0035] In one possible implementation, the fixing structure 4 includes three arc-shaped fixing pieces 41, which are equally spaced and fixedly disposed on the right side of the boss 13. The three arc-shaped fixing pieces 41 are arranged in a ring, with a notch formed between adjacent arc-shaped fixing pieces 41. The second rope clamp 6 is fixedly disposed on any one of the arc-shaped fixing pieces 41. The right end of the working wire rope 3 passes through one of the notches near the second rope clamp 6, is fixed by the third rope clamp 7, and then wound around the rope groove 12. The number of second rope clamps 6 is set according to requirements. Depending on the specific winding situation of the working wire rope 3, the second rope clamps 6 are fixed in appropriate positions to secure the working wire rope 3. Depending on the winding direction of the working wire rope 3, the right end of the working wire rope 3 passes through one of the notches in the winding direction.

[0036] As one possible implementation, multiple second rope clamps 6 (only one is shown for illustration in this embodiment) are provided. Each second rope clamp 6 includes a second fixing cylinder 61 and a second fixing block 62. The second fixing cylinder 61 is fixedly mounted on the second fixing block 62. The second fixing block 62 is provided with a second slot 621. Each arc-shaped fixing piece 41 is provided with multiple second screw holes 411. The arc-shaped fixing piece 41 is provided with three second screw holes 411. The second bolt 63 passes through the second fixing cylinder 61 and the second screw holes 411 and is fixedly connected to the fastening nut 64. The second slot 621 faces one of the arc-shaped fixing pieces 41. The left end of the working wire rope 3 is stuck between the second slot 621 and one of the arc-shaped fixing pieces 41. Depending on the specific winding of the working wire rope 3, the second bolt 63 passes through the second fixed cylinder 61 and the second screw hole 411 and is fixedly connected to the fastening nut 64. The second rope clamp 6 is fixed to the arc-shaped fixing plate 41, and the left end of the working wire rope 3 is fixed between the second slot 621 and the arc-shaped fixing plate 41.

[0037] In one possible implementation, the right portion of the drum body 1 is divided into a first region and a second region, with the third rope clamp 7 located in the first region and the rope groove 12 located in the second region. Preferably, the outer wall of the drum body 1 corresponding to the first region is a smooth surface, reducing the difficulty and production cost of manufacturing the drum body 1.

[0038] As one possible implementation, multiple third rope clamps 7 (only one is shown for illustration in this embodiment) are provided. Each third rope clamp 7 includes a third fixing block 71. The third fixing block 71 is provided with a central screw hole 711 and two third slots 712 located on both sides of the central screw hole 711. A third screw hole is provided on the right side of the drum body 1. The screw 72 passes through the central screw hole 711 and the third screw hole and is fixed to the right side of the drum body 1 by a clamping nut 73. There are two clamping nuts 73. The two third slots 712 face the outer wall of the right side of the drum body 1. The right end of the working wire rope 3 is clamped between the two third slots 712 and the right side of the drum body 1. Preferably, there are six third rope clamps 7, which are arranged in a ring. After the screw 72 passes through the central screw hole 711 and the third screw hole, it is fixed to the right side of the drum body 1 by the clamping nut 73. The third rope clamp 7 is fixed to the right side of the drum body 1. The right end of the working wire rope 3 is fixed between the third slot 712 and the right side of the drum body 1.

[0039] As one possible implementation, the left end of the rope groove 12 is a certain distance from the left baffle 11, and the right end of the rope groove 12 is a certain distance from the right baffle 11, so as to avoid stress concentration between the rope groove 12 and the baffle 11 and improve the service life of the drum body 1.

[0040] As one possible implementation, the baffle 11 on the right side is provided with multiple limiting holes 111 arranged in a ring. The multiple limiting holes 111, in conjunction with an external limiting device, mechanically lock the drum body 1 to prevent the drum body 1 from rotating out of control. In this embodiment, the drum body 1 can be fixedly mounted with a shaft for subsequent rotation.

[0041] The embodiments described above are merely preferred embodiments of the present invention and are only used to explain the present invention. They are not intended to limit the scope of the present invention. For those skilled in the art, other implementation methods can be easily made by substitution or modification based on the technical content disclosed in this specification. Therefore, all changes and improvements made to the principles and process conditions of the present invention should be included within the scope of the patent application of the present invention.
