Abstract
Description
Technical Field
[0001] This utility model relates to the field of rope guides, specifically an anti-wear device for an electric hoist rope guide. Background Technology
[0002] The wire rope guide is a key component of the electric hoist, consisting of a guide nut, a guide plate, and a connecting steel strip. Its function is to ensure that the wire rope is neatly arranged on the drum, preventing confusion and overlap, thereby avoiding mechanical failure and extending the equipment's lifespan. The wire rope guide moves axially through the threaded grooves of the drum, enabling accurate introduction and extraction of the wire rope.
[0003] Existing electric hoist rope guides can ensure that the wire rope is neatly and orderly arranged on the drum. However, during use, since the wire rope needs to pass through the placement groove on the rope guide, when the wire rope is carrying a heavy load, the wire rope may rub against one end of the placement groove, causing varying degrees of wear on the placement groove on the rope guide, thereby shortening the service life of the rope guide and reducing the ease of use of the rope guide. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide an anti-wear device for the rope guide of an electric hoist, so as to solve the technical problem that the wire rope may rub against both ends of the placement groove, causing wear on the placement groove on the rope guide and thus shortening the service life of the rope guide.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-wear device for an electric hoist rope guide, comprising a tightening roller, a rope guide body mounted on the surface of the tightening roller, the rope guide body comprising multiple supports, a connecting seat provided on one side of the supports, a first mounting plate provided on one side of the connecting seat, a placement groove provided on the surface of the first mounting plate, a limiting mechanism provided on the surface of the first mounting plate, the limiting mechanism comprising two sets of movable grooves, a second mounting plate being threadedly connected to the top of the two sets of movable grooves by bolts, a vertical plate being provided on the top of the second mounting plate, and a fixed pulley being rotatably connected between the two sets of vertical plates.
[0006] By adopting the above technical solution, the main body of the rope guide is first fitted into the outside of the tightening roller. Then, the bolts on the mounting plate are tightened to slide the fixed pulley in the movable groove until it reaches the optimal position. Then, the bolts are tightened in the opposite direction to make the limiting mechanism firmly installed on the main body of the rope guide. At this time, one side of the wire rope is in close contact with the fixed pulley, and the fixed pulley provides a clear guiding path for the wire rope, enabling it to move smoothly along the predetermined trajectory.
[0007] Furthermore, the two sets of movable slots are located on both sides of the placement slot and have a straight slot structure, which are used to provide installation points for the second mounting plate.
[0008] By adopting the above technical solution, the mounting plate can slide smoothly inside, ensuring that the fixed pulley can be adjusted to the optimal position as needed.
[0009] Furthermore, both sets of the second mounting plates are curved in shape, and their inner sides abut against the first mounting plate.
[0010] By adopting the above technical solution, the mounting plate can better fit the contour of the rope guide body during installation, which not only enhances the stability of the structure, but also ensures that the fixed pulley and the limiting mechanism can be firmly installed on the rope guide body.
[0011] Furthermore, a limiting groove is formed on the outer surface of the fixed pulley, and the width of the limiting groove is adapted to the width of the placement groove to limit the movement of the wire rope.
[0012] By adopting the above technical solution, it is ensured that the wire rope can maintain a stable operating state inside the rope guide and will not deviate from the track due to external forces or its own weight, thereby avoiding wear or damage caused by wire rope misalignment.
[0013] Furthermore, the bracket is provided in multiple parts, and has wire grooves inside, which are rotatably connected by movable seats.
[0014] By adopting the above technical solution, the correct direction of the wire rope inside the support is ensured, avoiding wear and damage caused by wire rope misalignment or slippage. At the same time, the support is rotatably connected through the movable seat.
[0015] Furthermore, the surface of the tightening roller is provided with take-up grooves, which are arranged in a bolt-like manner to provide placement points for the wire rope.
[0016] By adopting the above technical solution, it is ensured that the wire rope can be arranged in an orderly and tight manner on the tensioning roller, and will not easily slip or deviate from the predetermined trajectory due to external force or its own weight.
[0017] Furthermore, multiple connecting seats are provided and arranged in an equidistant circular pattern.
[0018] By adopting the above technical solution, not only is the overall structural stability of the rope guide enhanced, but it also provides multiple connection points, enabling the rope guide to be installed more securely in the required position.
[0019] In summary, the present invention has the following main advantages:
[0020] 1. This utility model uses a limiting mechanism to first insert the main body of the rope guide into the outer side of the tightening roller. Then, the bolts on the mounting plate are tightened to slide the fixed pulley in the movable groove until it moves to the appropriate position. Then, the bolts are tightened in the opposite direction to make the limiting mechanism firmly installed on the main body of the rope guide. At this time, one side of the wire rope is in close contact with the fixed pulley. The fixed pulley provides a clear guiding path for the wire rope, allowing it to move along the predetermined trajectory. Due to the existence of the limiting mechanism, one side of the wire rope will rub against the limiting mechanism, thereby avoiding direct friction between the wire rope and the placement groove. This effectively reduces the wear of the wire rope on the placement groove of the rope guide, thereby improving the service life of the rope guide and enhancing its ease of use.
[0021] 2. By setting a limiting groove in the fixed pulley, the wire rope is firmly confined within the groove and will not deviate from the predetermined path due to external forces or vibrations. This stability is crucial for improving the overall performance and safety of the rope guide. At the same time, the existence of the limiting groove also reduces friction and wear between the wire rope and the fixed pulley. Since the wire rope is accurately guided within the limiting groove, it will not have unnecessary contact with other parts of the fixed pulley, thereby reducing the risk of wear.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0030] The embodiments of this utility model will be described below based on its overall structure.
[0031] Example 1:
[0032] A wear-resistant device for the rope guide of an electric hoist, such as Figure 1 - Figure 4As shown, the device includes a tightening roller 1, on the surface of which a rope guide body 3 is mounted. The rope guide body 3 includes multiple brackets 301. A connecting seat 6 is provided on one side of each bracket 301, and a first mounting plate 5 is provided on one side of each connecting seat 6. The first mounting plate 5 has a placement groove 9 on its surface and a limiting mechanism 7 on its surface. The limiting mechanism 7 includes two sets of movable grooves 701. The tops of the two sets of movable grooves 701 are threadedly connected to a second mounting plate 702 by bolts 705. A vertical plate 703 is provided on the top of the second mounting plate 702. A fixed pulley 704 is rotatably connected between the two sets of vertical plates 703. First, the rope guide body 3 is fitted onto the outside of the tightening roller 1, and then the second mounting plate 704 is screwed on. Bolts 705 on mounting plate 702 are used to slide the fixed pulley 704 in the movable groove 701 until it reaches the optimal position. Then, bolts 705 are turned in the opposite direction to make the limiting mechanism 7 firmly installed on the rope guide body 3. At this time, one side of the wire rope is in close contact with the fixed pulley 704. The fixed pulley 704 provides a clear guiding path for the wire rope, allowing it to move smoothly along the predetermined trajectory. Due to the presence of the limiting mechanism 7, one side of the wire rope will generate slight friction with the limiting mechanism 7, avoiding direct friction between the wire rope and the placement groove 9, thereby reducing the wear of the wire rope on the placement groove of the rope guide. This not only improves the service life of the rope guide but also greatly enhances its ease of use.
[0033] See Figure 1 , Figure 3 , Figure 4 Two sets of movable grooves 701 are located on both sides of the placement groove 9 and have a straight groove structure. They are used to provide installation points for the second mounting plate 702, allowing the second mounting plate 702 to slide smoothly inside. This ensures that the fixed pulley 704 can be adjusted to the optimal position as needed. At the same time, it simplifies the installation and debugging process, allowing users to easily fix the second mounting plate 702 in the required position and fine-tune the position of the fixed pulley 704 by tightening the bolts 705. This ensures that the wire rope is accurately guided. They provide sufficient space for the limiting mechanism 7, allowing the limiting mechanism 7 to effectively contact the wire rope and generate appropriate friction, avoiding direct friction between the wire rope and the placement groove 9, thereby reducing wear and extending the service life of the rope guide.
[0034] See Figure 1 , Figure 3 , Figure 4Both sets of second mounting plates 702 have an overall curved structure, and their inner sides abut against the first mounting plate 5. This allows the second mounting plates 702 to better conform to the contour of the rope guide body 3 during installation, which not only enhances the stability of the structure but also ensures that the fixed pulley 704 and the limiting mechanism 7 can be firmly installed on the rope guide body 3. At the same time, during the installation process, due to the tight contact between the second mounting plates 702 and the first mounting plates 5, the tension from the wire rope can be effectively distributed and borne, avoiding structural damage caused by local stress concentration. Furthermore, when the second mounting plates 702 are subjected to external forces, they can evenly transmit the force to the rope guide body 3, thereby improving the tensile strength and durability of the entire rope guide.
[0035] Example 2:
[0036] See Figure 1 , Figure 4 The outer surface of the fixed pulley 704 is provided with a limiting groove, which is adapted to the width of the placement groove 9. This groove is used to limit the wire rope, ensuring that the wire rope can maintain a stable running state inside the rope guide and will not deviate from the track due to external forces or its own weight. This avoids wear or damage caused by wire rope misalignment. At the same time, the matching width of the limiting groove and the placement groove 9 ensures that the wire rope can always maintain an appropriate distance from the main body 3 of the rope guide during operation. This further reduces the friction between the wire rope and other parts of the rope guide and extends the service life of the rope guide.
[0037] See Figure 1 , Figure 3 Multiple brackets 301 are provided, and each has an internal guide groove 8. These grooves are rotatably connected via movable seats 4, ensuring the correct routing of the wire rope within the brackets and preventing wear and damage caused by misalignment or slippage. The rotatable connection of brackets 301 via movable seats 4 also allows for stable mounting on the tensioning roller 1. Supported by the movable seats 4, brackets 301 can be easily rotated and fine-tuned, ensuring optimal operating conditions for the wire rope within the rope guide.
[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4The surface of the tensioning roller 1 is provided with take-up grooves 2, which are arranged in a bolt-like manner to provide placement points for the wire rope. This ensures that the wire rope can be arranged in an orderly and tight manner on the tensioning roller, and will not easily slip or deviate from the predetermined trajectory due to external forces or its own weight. At the same time, the bolt-like arrangement of the take-up grooves 2 makes the distribution of the wire rope on the tensioning roller 1 more uniform, avoiding wear or damage caused by local stress concentration. This uniform distribution also improves the gripping force of the tensioning roller 1 on the wire rope, ensuring that the wire rope can maintain stable tension during the tightening process, thereby improving the overall performance of the rope guide.
[0039] See Figure 1 , Figure 2 , Figure 3 Multiple connecting seats 6 are provided and arranged in an equidistant circular pattern. This not only enhances the overall structural stability of the rope guide but also provides multiple connection points, allowing the rope guide to be installed more securely in the required position. At the same time, the connecting seats 6 enable the rope guide to distribute pressure more evenly when under stress, avoiding structural damage caused by local stress concentration. This even distribution also improves the load-bearing capacity of the rope guide, enabling it to cope with more complex and severe working conditions.
[0040] The implementation principle of this utility model is as follows: First, the main body 3 of the rope guide is sleeved into the outer side of the tightening roller 1. Then, the bolt 705 on the second mounting plate 702 is turned to slide the second mounting plate 702 and the vertical plate 703 in the movable groove 701, and drive the fixed pulley 704 to slide until it moves to a suitable position. Then, the bolt 705 is turned in the opposite direction to install the limiting mechanism 7 on the main body 3 of the rope guide. Through this adjustment method, the position of the fixed pulley 704 can be adjusted according to the specific use environment, thereby improving its environmental usability. At this time, one side of the wire rope abuts against the fixed pulley 704, and the fixed pulley 704 can guide the wire rope, so that the direction of the wire rope changes. Due to the existence of the limiting mechanism 7, the direct friction between the wire rope and the placement groove 9 is reduced, thereby reducing the wear of the wire rope on the placement groove 9 of the rope guide, thus improving the service life of the rope guide and improving the ease of use of the rope guide.
