Description

Technical Field

[0001] This utility model relates to the field of rope guide technology, and in particular to a crane drum rope guide. Background Technology

[0002] Crane drums are an important component of cranes. When a crane lifts an object, the wire rope should be neatly arranged on the outer layer of the drum. If the rope is pressed or wrapped, accidents are likely to occur. The rope guide on the drum plays a role in guiding the wire rope to be arranged neatly.

[0003] Currently, the rope guides used on cranes are conventional types. When the crane is pulling at an angle, wire rope misalignment or compression can easily occur, causing the drum to malfunction and affecting production. This necessitates rearranging the wire rope on the outer circumference of the drum, requiring crane maintenance workers to remove the rope guide, wind the wire rope around the drum one turn at a time, and then reinstall the rope guide. Disassembling and reassembling the rope guide consumes a significant amount of time, greatly reducing production efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a crane drum rope guide. By pressing the button, the insertion post is pressed and will disengage from the fixing box. At this time, the rope guide pressure plate can be removed. When the rope guide pressure plate is removed, the first half ring and the second half ring can be removed from the drum, which can be quickly disassembled and replaced, reducing the time consumption during maintenance and making fault repair more efficient.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0024] 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.

[0025] Reference Figure 2 - Figure 4 This utility model provides an embodiment of a crane drum rope guide, comprising: a first half-ring 1 serving as the connecting body; a second half-ring 2 rotatably connected to both sides of the outer wall of the first half-ring 1; a fixing block 3 fixedly connected to the outer wall of each of the second half-ring 2; a limit plate 4 fixedly connected to the outer wall of each of the fixing blocks 3; a pin 5 fixedly connected to the opposite end of each limit plate 4; a first spring 6 provided between the limit plate 4 and the inner wall of each fixing block 3; a rope guide pressure plate 7 slidably connected to the outer wall of the fixing block 3; and fixing boxes 8 fixedly connected to both sides of the outer wall of the rope guide pressure plate 7. A fixed cylinder 9 is fixedly connected to each of the opposite ends. A sliding plate 10 is slidably connected to the inner wall of each fixed cylinder 9. A button 11 is fixedly connected to the inner wall of each sliding plate 10. A second spring 12 is provided between the inner walls of the fixed cylinder 9 and the sliding plate 10. An adjustment component is provided on the inner wall of the rope guide plate 7. One end of each first spring 6 is connected to the limiting plate 4. The other end of each first spring 6 is connected to the inner wall of the fixed block 3. One end of each second spring 12 is connected to the sliding plate 10. The other end of each second spring 12 is connected to the inner wall of the fixed cylinder 9. A wire groove 18 is provided on the inner wall of the rope guide plate 7.

[0026] Specifically, when it is necessary to disassemble the crane drum rope guide, simply press button 11. After the button 11 is applied, it will push the insert 5 to move, causing it to disengage from the fixed box 8. After the insert 5 is disengaged, the rope guide pressure plate 7 can be easily removed. Then, with the rope guide pressure plate 7 removed, the first half ring 1 and the second half ring 2 can be easily removed from the drum. This achieves quick disassembly, greatly reducing the time consumed during maintenance and making fault repair more efficient. During installation, first place the rope guide pressure plate 7 above the fixed block 3. When the two are in place, the first spring 6 will push the limit plate 4 due to its elasticity. After the limit plate 4 is bounced, it will drive the insert 5 to move, allowing the insert 5 to be smoothly inserted into the fixed box 8, completing the initial fixation. Then, release button 11. At this time, the second spring 12 will play its role, lifting the slide plate 10. The bounce of the slide plate 10 will drive the button 11 to move, returning the button 11 to its initial position, completing the entire installation process.

[0027] Reference Figure 1 , Figure 2 and Figure 5 The adjustment assembly includes a fixed frame 14 that is slidably connected to both sides of the inner wall of the rope guide plate 7. A pull rod 15 is slidably connected to the inner wall of the fixed frame 14. A fixed plate 16 is fixedly connected to the outer wall of the pull rod 15. A third spring 17 is provided between the fixed plate 16 and the inner wall of the fixed frame 14. A positioning plate 13 is fixedly connected to the top of the fixed frame 14. The outer wall of the positioning plate 13 is slidably connected to the inner wall of the rope guide plate 7. The outer wall of the fixed plate 16 is slidably connected to the inner wall of the fixed frame 14. A plurality of fixing holes 19 are provided on the inner wall of the rope guide plate 7 corresponding to the pull rod 15. One end of the third spring 17 is connected to the fixed plate 16, and the other end of the third spring 17 is connected to the inner wall of the fixed frame 14.

[0028] Specifically, when positioning the steel cable is required, first pull the lever 15. After the lever 15 is under force, it will be pulled out from the fixing hole 19. After the lever 15 is separated from the fixing hole 19, the fixing frame 14 can be pulled. As the fixing frame 14 is pulled, the positioning plate 13 will also move. After the positioning plate 13 moves to the appropriate position, it can position the steel cable, effectively preventing the steel cable from getting tangled on the drum, thus avoiding problems such as the steel cables squeezing each other and jumping off the drum. After the positioning operation is completed, release the lever 15. Once the lever 15 is released, the third spring 17 will bounce the fixing plate 16 with its own elasticity. When the fixing plate 16 is bounced, it will drive the lever 15 to move. Finally, the lever 15 will be inserted back into the fixing hole 19, thereby fixing the positioning plate 13 in the current position and ensuring the stable maintenance of the positioning state.

[0029] Working principle: First, when disassembly is required, press button 11 to move the insert 5. When the insert 5 is moved, it will disengage from the inside of the fixing box 8. At this time, remove the rope guide plate 7. When the rope guide plate 7 is removed, remove the first half ring 1 and the second half ring 2 from the drum, which allows for quick disassembly and replacement, reducing maintenance time and making fault repair more efficient. During installation, insert the rope guide plate 7 onto the fixing block 3. When they are in place, the first spring 6 will spring the limiting plate 4. When the limiting plate 4 is springed, it will drive the insert 5 to move. When the insert 5 moves, it will insert into the fixing box 8 and be fixed. When button 11 is released, the second spring 12 will... The slide plate 10 is bounced, which moves the button 11. The button 11 resets as it moves. When positioning is required, the pull rod 15 is pulled to disengage it from the fixing hole 19. At this time, the fixing bracket 14 is pulled to move the positioning plate 13. When the positioning plate 13 moves, it positions the steel cable, thus preventing the steel cable from getting tangled on the drum and avoiding problems such as the steel cables squeezing each other or jumping off the groove. Then the pull rod 15 is released. When the pull rod 15 is released, the third spring 17 bounces the fixing plate 16. When the fixing plate 16 bounces, it moves the pull rod 15. When the pull rod 15 moves, it inserts into the fixing hole 19 for fixation.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
