Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting equipment technology, specifically a wire rope lifting equipment. Background Technology
[0002] Wire rope slings are widely used in industrial lifting operations. Their structural design directly affects lifting safety and efficiency. Traditional slings often use fixed connection structures, which have significant drawbacks: the stress transfer path between the hook and connecting components is singular, easily leading to localized stress concentration, which may cause metal fatigue or fracture with long-term use; the hook lacks an effective anti-detachment mechanism, making it prone to accidental opening under vibration or dynamic loads, causing safety hazards. Furthermore, traditional slings often use fixed lifting rings or hooks at the end, making them difficult to adapt to irregularly shaped heavy objects or special lifting points, often requiring additional clamps, resulting in complex operation and increased costs. These problems limit the adaptability and reliability of slings under complex working conditions.
[0003] In dynamic lifting scenarios, the inadequacies of traditional lifting devices in terms of buffering and adjustment become even more apparent. The sliders and grooves of sliding rail-type lifting devices rely heavily on rigid contact, making them prone to jamming or even deformation under lateral impacts. The instantaneous impact forces generated by sudden load changes lack a buffering mechanism, accelerating component wear. Existing adjustment mechanisms often require manual tightening of bolts, which is cumbersome and prone to loosening during vibrations, affecting the stability of the lifting points. Furthermore, the redundant connections between components in traditional lifting devices and their low degree of modularity result in a bulky overall structure and reduced rigidity.
[0004] Therefore, in response to the above problems, it is necessary for the applicant to design a wire rope lifting device to solve the problem. Utility Model Content
[0005] The purpose of this utility model is to provide a wire rope lifting device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire rope lifting device, comprising a wire rope, wherein one end of the wire rope is provided with a first connecting sleeve, and a fixing ring is provided on the first connecting sleeve.
[0007] It also includes: a suspension assembly connected to the fixing ring, and the suspension assembly includes a hook disposed inside the fixing ring;
[0008] A second connecting sleeve is integrally connected to the end of the wire rope away from the first connecting sleeve. A second fixing ring is connected to the second connecting sleeve, and a mounting plate is fixedly installed on the second fixing ring. A support frame is fixedly installed on the mounting plate, and a sliding groove is provided below the support frame. A slider is slidably installed inside the sliding groove, and a connector is fixedly installed on the slider. A third connecting sleeve is connected to the connector, and a lifting rope is connected to the third connecting sleeve.
[0009] Furthermore, a fixing rod is integrally provided on the hook, and a fixing member is fixedly provided at the end of the fixing rod away from the hook. An installation member is fixedly provided on the fixing member, and the installation member is connected to an external fixing object.
[0010] Through the above structural design, the integrated connection structure of the fixing rod, fixing parts and mounting parts can distribute the force of the hook to the external fixed object, avoiding local stress concentration.
[0011] Furthermore, a spring is fixedly installed on the fixing rod, and the spring abuts against the hook.
[0012] Through the above structural design, the addition of a spring plate to the fixed rod that contacts the hook can apply continuous elastic pressure to the hook, effectively preventing the hook from accidentally coming off due to vibration or external interference.
[0013] Furthermore, a fourth connecting sleeve is provided at the end of the lifting rope away from the third connecting sleeve, and an installation ring is provided on the fourth connecting sleeve. An installation screw is threaded onto the installation ring, and the installation screw is used to lift heavy objects.
[0014] Through the above structural design, and by cooperating with the fourth connecting sleeve, the mounting ring, and the mounting screw, an adjustable connection between the end of the lifting rope and the load is achieved.
[0015] Furthermore, telescopic rods are fixedly provided on both sides of the slider, and an extension block is fixedly provided at the end of the telescopic rod away from the slider, and the extension block is slidably connected to the slide groove.
[0016] The above structural design makes it easy to install the slider in the groove, and the slider always maintains multi-point contact support through the extension block when sliding in the groove, which greatly reduces the risk of jamming caused by the slider being subjected to force on one side.
[0017] Furthermore, a spring is fixedly installed on the slider, and the end of the spring away from the slider is fixedly connected to the extension block.
[0018] Through the above structural design, the spring connects the slider and the extension block, which can absorb energy through spring deformation when the lifting device is subjected to impact load, thereby reducing the damage to the slide structure caused by instantaneous impact.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] This wire rope lifting device significantly improves functionality and safety through multi-dimensional structural optimization: its integrated connection structure disperses hook stress and enhances load-bearing stability, making it suitable for long-term fixed scenarios; the spring plate design forms a dynamic anti-derailment mechanism, ensuring reliable locking under lifting vibration environments; the adjustable threaded connection scheme expands the device's adaptability to irregularly shaped heavy objects and simplifies the assembly and disassembly process; the combination of telescopic rod and extension block optimizes the sliding stability of the slide groove through multi-point support, reducing the risk of jamming and improving durability; the spring buffer effectively absorbs impact loads while adaptively adjusting the contact state, balancing smooth sliding and structural damage resistance. These improvements work synergistically to achieve a comprehensive performance improvement in the lifting device's load-bearing strength, safety protection, working condition adaptability, and mechanical durability.

[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 1-5As shown, this utility model discloses a wire rope lifting device, including a wire rope 1. The wire rope 1 is a helical bundle of steel wires that meet the requirements of mechanical properties and geometric dimensions, twisted together according to certain rules. One end of the wire rope 1 is provided with a first connecting sleeve 2, and the first connecting sleeve 2 is provided with a fixing ring 3. It also includes: a hanging assembly connected to the fixing ring 3, and the hanging assembly includes a hook 7 disposed inside the fixing ring 3; a second connecting sleeve 9 integrally connected to the end of the wire rope 1 away from the first connecting sleeve 2, a second fixing ring 10 connected to the second connecting sleeve 9, and a mounting plate 11 fixedly disposed on the second fixing ring 10. A support frame 12 is fixedly disposed on the mounting plate 11, and a sliding groove 13 is provided below the support frame 12. A slider 14 is slidably disposed inside the sliding groove 13, and a connector 15 is fixedly disposed on the slider 14. A third connecting sleeve 16 is connected to the connector 15, and a lifting rope 17 is connected to the third connecting sleeve 16.
[0029] A fixing rod 6 is integrally provided on the hook 7, and a fixing member 5 is fixedly provided at the end of the fixing rod 6 away from the hook 7. An installation member 4 is fixedly provided on the fixing member 5, and the installation member 4 is connected to an external fixed object. Through the integrated connection structure of the fixing rod 6, the fixing member 5 and the installation member 4, the force of the hook 7 can be distributed and transferred to the external fixed object, avoiding local stress concentration. The connection method between the installation member 4 and the external object simplifies the installation process and improves the stability and load-bearing capacity of the overall structure, which is especially suitable for scenarios that require long-term fixed suspension.
[0030] A spring piece 8 is fixedly installed on the fixed rod 6, and the spring piece 8 abuts against the hook 7. The design of adding a spring piece 8 to the fixed rod 6 and abutting against the hook 7 can apply continuous elastic pressure to the hook 7, effectively preventing the hook 7 from accidentally coming off due to vibration or external interference. This structure significantly improves the safety of hoisting operations while ensuring the flexibility of opening and closing the hook 7, and is especially suitable for dynamic hoisting environments.
[0031] A fourth connecting sleeve 18 is provided at the end of the lifting rope 17 away from the third connecting sleeve 16, and an installation ring 19 is provided on the fourth connecting sleeve 18. An installation screw 20 is threaded on the installation ring 19, and the installation screw 20 is used to lift heavy objects. Through the cooperation of the fourth connecting sleeve 18, the installation ring 19 and the installation screw 20, an adjustable connection between the end of the lifting rope 17 and the heavy object is realized. The threaded installation method not only facilitates quick assembly and disassembly of heavy objects, but also allows for flexible adjustment of the fixed position according to the load characteristics, enhancing the adaptability of the lifting device to heavy objects of different shapes and sizes, and reducing the need for special clamps.
[0032] Telescopic rods 140 are fixedly installed on both sides of the slider 14. An extension block 141 is fixedly installed at the end of the telescopic rod 140 away from the slider 14, and the extension block 141 is slidably connected to the slide groove 13. The telescopic rods 140 and extension blocks 141 on both sides of the slider 14 ensure that the slider 14 always maintains multi-point contact support through the extension blocks 141 when sliding in the slide groove 13. This greatly reduces the risk of jamming caused by the slider 14 being subjected to force on one side. At the same time, the telescopic structure compensates for the dimensional error between the slide groove 13 and the slider 14, ensuring a smooth sliding process and better durability, and facilitating the installation of the slider 14 in the slide groove 13.
[0033] A spring 142 is fixedly installed on the slider 14, and the end of the spring 142 away from the slider 14 is fixedly connected to the extension block 141. The spring 142 connects the slider 14 and the extension block 141. When the lifting device is subjected to impact load, the deformation of the spring 142 can absorb energy and reduce the damage of instantaneous impact to the slide groove 13 structure. In addition, the preload of the spring 142 can automatically adjust the contact state between the extension block 141 and the slide groove 13, which not only ensures smooth sliding, but also avoids the problem of gap expansion caused by wear.
[0034] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
