Description

Technical Field

[0001] This utility model relates to the field of boom lift technology, specifically a replaceable boom lift hook. Background Technology

[0002] The hook on the hooklift is the key actuator of the hooklift garbage truck. Through a high-strength alloy hook body (such as 34CrNiMo6) precisely engaging with the garbage container's lifting ring, it enables the entire process of hooking, lifting, transferring, unloading, and resetting the container. Its core adopts a modular and replaceable design, with the main structure integrating a triple interlocking system (dovetail groove guidance + tapered pin shear resistance + hydraulic ring dynamic locking), completely eliminating the risk of loosening and failure associated with traditional bolted connections. The hook body's working surface is laser-coated with a WC-Co / Ni-based gradient wear-resistant coating (hardness ≥ HRC 65), extending its lifespan by more than 3 times, and a fiber optic sensing interface is reserved for real-time monitoring of load status. This design significantly improves equipment reliability, maintenance efficiency, and operational adaptability, making it suitable for high-frequency operation scenarios such as urban sanitation and industrial solid waste disposal.

[0003] During the operation of installing hooks on booms, the equipment needs to withstand dynamic impact loads and high-frequency vibrations. These mechanical characteristics directly affect the equipment's lifespan, safety, and operational accuracy. Long-term use can also affect the use of hooks installed on booms. Therefore, we propose a replaceable hook for booms. Utility Model Content

[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] Please see Figures 1-5 This utility model provides a technical solution:

[0026] A replaceable boom hook includes: a hook mounting block 1, a connecting rotating block 2 fixedly connected to the top of the hook mounting block 1, and a hanging ring 3 provided on the inner wall of the connecting rotating block 2, the size of the hanging ring 3 matching the size of the inner wall of the connecting rotating block 2. The hook mounting block 1 is characterized in that: a hook block body 4 is fixedly connected to the bottom of the hook mounting block 1, an auxiliary buffer assembly 5 is fixedly connected to the top of the hanging ring 3, and a shock-absorbing assembly 6 is provided on the top of the auxiliary buffer assembly 5.

[0027] In this embodiment, the hook mounting block 1 can install the hook block body 4 into the hanging ring 3 at the bottom of the auxiliary buffer component 5 through the connecting rotating block 2, thereby helping to stabilize the installation of the hook block body 4. At the same time, the auxiliary buffer component 5, together with the shock absorption component 6, buffers the high-frequency vibration generated by the device during use, thereby improving the overall functionality and service life of the device.

[0028] The shock absorption assembly 6 includes a connecting plate 601, a shock absorption base 602, a buffer spring 603, a damper 604, a connecting column 605, a connecting mounting block 606, and a detachable mounting screw 607. The connecting plate 601 is fixedly connected to the top of the auxiliary buffer assembly 5, and multiple shock absorption bases 602 are fixedly connected to the top of the connecting plate 601.

[0029] In this embodiment, the shock absorption component 6 is fixed to the top of the auxiliary buffer component 5 by the connecting plate 601, and multiple shock absorption bases 602 are used to provide a bottom buffer foundation for the buffer spring 603 and the damper 604, thereby improving the functionality of the shock absorption component 6.

[0030] All buffer springs 603 are fixedly connected to the top of the shock-absorbing base 602, and the damper 604 is disposed on the inner wall of the buffer spring 603. The dimensions of the buffer spring 603 and the damper 604 are matched with each other.

[0031] In this embodiment, the buffer spring 603 can work in conjunction with the damper 604. When subjected to an impact, the impact kinetic energy will cause the buffer spring 603 to compress or stretch, and the damper 604 will store elastic potential energy and release it slowly using the structure of the damper 604. This effectively buffers the impact generated by high-frequency vibration and uses this buffering structure to transform the instantaneous impact into a slow deformation process, thereby reducing the peak impact force and achieving the overall buffering function of the shock absorption component 6 to cope with high-frequency vibration, thus improving the safety and functionality of the shock absorption component 6.

[0032] The connecting mounting block 606 is fixedly connected to the top of the damper 604 and the buffer spring 603, and a plurality of detachable mounting screws 607 are provided on the inner wall of the connecting mounting block 606.

[0033] In this embodiment, the connecting mounting block 606, together with multiple detachable mounting screws 607, allows the entire device to be disassembled at any time to replace the hook block body 4 when it needs to be replaced, thereby improving the overall functionality and safety of the device.

[0034] The auxiliary buffer assembly 5 includes a mounting plate 501, a mounting groove 502, a corrugated buffer pad 503, and a reinforcing nail 504. The mounting plate 501 is fixedly connected to the top of the mounting ring 3, and the mounting groove 502 is formed in the inner wall of the mounting plate 501.

[0035] In this embodiment, the auxiliary buffer component 5 can be fixed to the top of the mounting ring 3 by the mounting plate 501, and the mounting groove 502 provides internal space for the auxiliary buffer structure of the auxiliary buffer component 5.

[0036] Multiple corrugated buffer pads 503 are fixedly connected to the inner wall of the mounting groove 502, and the shapes of the multiple corrugated buffer pads 503 are matched with each other.

[0037] In this embodiment, the corrugated buffer pad 503 can efficiently disperse stress. The core of this is the synergistic effect of its corrugated geometric configuration and elastic deformation mechanism. By changing the contact state, inducing multi-level deformation, and optimizing the pressure distribution, stress redistribution is achieved, thereby assisting in stress dispersion of the buffer and further improving the auxiliary buffering effect of the device.

[0038] Multiple reinforcing nails 504 are disposed on the top of the mounting plate 501, and the reinforcing nails 504 are evenly distributed.

[0039] In this embodiment, the reinforcing nail 504 can help fix the mounting plate 501 to the bottom of the connecting plate 601. This connection is used to further assist in the cushioning of the shock-absorbing component 6 and improve the overall cushioning effect of the device during use.

[0040] Working principle: The device uses the hook mounting block 1 to help fix the connecting rotating block 2, and the hook block body 4 is hung at the bottom, thus providing an installation base for the use of the hook block body 4. The mounting ring 3 can fix the hook mounting block 1 to the bottom of the auxiliary buffer component 5 by connecting the rotating block 2. At the same time, the structure of the auxiliary buffer component 5 is used to buffer the structure of the shock absorption component 6 to withstand dynamic impact loads and high-frequency vibrations during the use of the device, thereby improving the overall safety and functionality of the device.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
