Technical Field
[0001] This utility model relates to the technical field of hoist accessories, and in particular to a rope changing device for a vertical shaft hoist. Background Technology
[0002] In vertical shaft hoisting systems, the hoisting rope, as a critical component, endures heavy loads and frequent alternating stresses over long periods, making it prone to wear, fatigue fracture, and other problems, necessitating periodic replacement. Currently, traditional methods for replacing ropes in vertical shaft hoists have numerous drawbacks. For example, manual rope replacement is cumbersome, labor-intensive, and time-consuming, severely impacting normal mine production. Furthermore, inaccurate tension control during rope replacement can easily lead to uneven stress on the hoisting rope, potentially causing safety accidents.
[0003] Therefore, it is necessary to replace the hoisting rope using a rope-changing device. However, existing devices have certain drawbacks in use. For example, Chinese patent with publication number "CN 217498375 U" discloses an efficient and simple rope-changing device for vertical shaft hoists. This device drives the take-up roller and the release roller to start simultaneously and rotate in opposite directions through a drive mechanism. Then, the new rope on the release roller is installed on the hoisting equipment by a rope-changing trolley. At the same time, the take-up roller recovers the old rope. Although this device can change the rope and does not require personnel to approach during the process, after the device completes the hoisting rope changing operation, it is inconvenient to remove the old rope that has been wound up on the device, requiring workers to waste time disassembling the wound-up old rope. Utility Model Content
[0004] This utility model proposes a rope changing device for a vertical shaft hoist to solve the problem that existing devices are inconvenient for removing old ropes.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rope changing device for a vertical shaft hoist, comprising a winding component and an unwinding component;
[0006] The take-up component includes a first bracket, on which two first rotating plates are rotatably connected. The first rotating plates are symmetrically formed with two first side holes along their own length direction. A detachable take-up roller is provided between the two first rotating plates. A first positioning hole is recessed on the take-up roller. A detachable first screw is screwed between the first positioning hole and the first side hole.
[0007] The unwinding component includes a second bracket, on which two second rotating plates are rotatably connected. The second rotating plates are symmetrically formed with two second side holes along their own length direction. A detachable unwinding roller is provided between the two second rotating plates. A second positioning hole is recessed on the unwinding roller. A detachable second screw is screwed between the second positioning hole and the second side hole.
[0008] Preferably, it also includes a support member, the support member including a base plate, one side of the base plate is recessed to form two slots, and the top of the two slots is open, and the bottom of the first bracket and the second bracket are fixedly connected to a connecting plate, the connecting plate matching the slot.
[0009] Preferably, a second connecting hole is formed on both sides of the symmetrical substrate, the two second connecting holes are respectively connected to two slots, and a first connecting hole matching the second connecting hole is provided on the connecting plate, and a detachable connecting rod is screwed between the second connecting hole and the first connecting hole.

[0027] 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.
[0028] like Figures 1-8 As shown, a rope changing device for a vertical shaft hoist includes a winding component 2 and an unwinding component 3.
[0029] The take-up component 2 includes a first bracket 23, on which two first rotating plates 24 are rotatably connected. The first rotating plates 24 are symmetrically formed with two first side holes 25 along their own length direction. A detachable take-up roller 26 is provided between the two first rotating plates 24. A first positioning hole 22 is recessed in the take-up roller 26. A detachable first screw 27 is screwed between the first positioning hole 22 and the first side hole 25.
[0030] The unwinding component 3 includes a second support 33, on which two second rotating plates 34 are rotatably connected. The second rotating plates 34 are symmetrically formed with two second side holes 35 along their own length direction. A detachable unwinding roller 36 is provided between the two second rotating plates 34. A second positioning hole 38 is formed in the unwinding roller 36. A detachable second screw 37 is screwed between the second positioning hole 38 and the second side hole 35.
[0031] With the above technical solution, when it is necessary to replace the lifting rope of the hoist, the take-up component 2 and the unwinding component 3 are placed on one side of the hoist. Then, the take-up roller 26 is placed between the two first rotating plates 24, and the first screw 27 is screwed into the first positioning hole 22 and the first side hole 25, thereby fixing the take-up roller 26 between the two first rotating plates 24. Then, the unwinding roller 36 is placed between the two second rotating plates 34, and the second screw 37 is screwed into the second positioning hole 38 and the second side hole 35, thereby fixing the unwinding roller 36 with the unused lifting rope between the two second rotating plates 34. One end of the worn lifting rope on the hoist is wound around the take-up roller 26. By rotating the first rotating plates 24 and the second rotating plates 34, the take-up roller 26 is driven to rotate. The take-up roller 26 and the unwind roller 36 rotate in opposite directions. The take-up roller 26 takes up the excessively worn lifting rope, and the unwound roller 36 releases the unused lifting rope, allowing the elevator to take up the unused lifting rope, thus completing the replacement of the lifting rope. After the lifting rope is replaced, the first screw 27 on the take-up roller 26 is unscrewed, allowing the take-up roller 26 to be removed from between the two first rotating plates 24, thus completing the recovery of the excessively worn lifting rope. The unloaded take-up roller 26 is then placed between the two first rotating plates 24, and the first screw 27 is screwed into the first positioning hole 22 and the first side hole 25, thus fixing the take-up roller 26 between the two first rotating plates 24 for easy recovery of the lifting rope next time.
[0032] Furthermore, in this utility model, the device also includes a support member 1, which includes a base plate 11. One side of the base plate 11 is recessed to form two slots 13, and the tops of the two slots 13 are open. The bottoms of the first bracket 23 and the second bracket 33 are fixedly connected to a connecting plate 4, which matches the slots 13.
[0033] In this embodiment, before using the device, the first bracket 23 and the second bracket 33 are respectively engaged with the two slots 13 via the connecting plate 4. The first bracket 23 and the second bracket 33 are supported by the base plate 11, thereby supporting the take-up roller 26 and the unwind roller 36. When the first bracket 23 or the second bracket 33 needs to be replaced, simply pull the first bracket 23 or the second bracket 33 to separate the connecting plate 4 from the slots 13, and the first bracket 23 or the second bracket 33 can be replaced.
[0034] After the connecting plate 4 is engaged with the slot 13, in order to improve the tightness of the first bracket 23 and the second bracket 33 during installation, the base plate 11 forms second connecting holes 16 on both sides symmetrically. The two second connecting holes 16 are respectively connected to the two slots 13, and the connecting plate 4 is provided with a first connecting hole 5 that matches the second connecting hole 16. A detachable connecting rod 14 is screwed between the second connecting hole 16 and the first connecting hole 5.
[0035] In this embodiment, after connecting the connecting plate 4 to the slot 13, the connecting rod 14 is screwed into the first connecting hole 5 and the second connecting hole 16, thereby making the connecting plate 4 and the base plate 11 more securely connected. When it is necessary to disassemble the first bracket 23 or the second bracket 33, simply unscrew the corresponding connecting rod 14 to disassemble the first bracket 23 or the second bracket 33.
[0036] In addition, regarding how the first rotating plate 24 and the second rotating plate 34 rotate, a drive gear 31 is rotatably connected to one side of the second bracket 33. The drive gear 31 rotates synchronously with one of the second rotating plates 34. A driven gear 21 is rotatably connected to one side of the first bracket 23. The driven gear 21 rotates synchronously with one of the first rotating plates 24, and the driven gear 21 meshes with the drive gear 31.
[0037] In this embodiment, when it is necessary to drive the first rotating plate 24 and the second rotating plate 34 to rotate, the driven gear 21 rotates, thereby driving the second rotating plate 34 to rotate. When the driven gear 21 rotates, it will synchronously drive the driving gear 31 to rotate. The driving gear 31 drives the driven gear 21 to rotate, so that the driven gear 21 drives the first rotating plate 24 to rotate.
[0038] Regarding how the drive gear 31 rotates, as follows: Figures 1-5 As shown, a motor 12 is fixedly connected to the top of the support member 1, and a positioning shaft 15 is connected to the output end of the motor 12. A hole 32 is formed by recessing one side of the drive gear 31, and the hole 32 matches the positioning shaft 15.
[0039] In this embodiment, the motor 12 operates, causing the positioning shaft 15 to rotate. The positioning shaft 15 engages with the insertion hole 32, thereby driving the drive gear 31 to rotate.
[0040] Furthermore, in this invention, in order to improve the stability of the substrate 11, such as... Figures 1-4 As shown, four base plates 17 are fixedly connected to the bottom of the substrate 11. The four base plates 17 are arranged in pairs and are symmetrical.
[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
