Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a hook assembly and a high-efficiency and stable lifting equipment. Background Technology

[0002] Lifting operations are a frequent and indispensable key link in the entire process of wheel rim manufacturing, logistics transportation, and warehousing management. Whether it is the process flow on the production line, finished product stacking in the warehouse, loading and shipping, or unloading and storage after arriving at the user's warehouse, specialized lifting equipment is needed to safely and efficiently lift, move, and place the wheel rims. However, the traditional wheel rim lifting equipment that is widely used at present has gradually revealed its inherent limitations in practice.

[0003] The primary issues are adaptability and safety. Many traditional lifting tools have relatively fixed or simple designs, and due to structural limitations or insufficient operational flexibility, they are prone to causing rim swaying, tilting, or even accidental slippage. This instability not only directly threatens the safety of workers but also easily causes quality damage such as rim surface scratches and collision deformation, resulting in additional economic losses and rework costs.

[0004] Secondly, a significant bottleneck is the lack of versatility. Modern wheel rim manufacturing often encompasses a wide range of product lines with various specifications, sizes, and hub bolt patterns. Many existing lifting tools are designed only for specific sizes, lacking effective adjustment or quick-change mechanisms. When the production line needs to switch between different wheel rim models, operators have to frequently change lifting tools or make complex adjustments, reducing overall production efficiency. Summary of the Invention

[0005] In this section, as well as in the abstract and title of this application, some simplifications or omissions may be made to avoid obscuring the purpose of this section, the abstract, and the title of this application.

[0006] To address the shortcomings of existing technologies, the primary objective of this invention is to provide a hook assembly for solving the problem of how to quickly and stably lift wheel hubs.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a hook assembly, comprising: an extrusion member, one end of which rotates around a first horizontal axis, wherein multiple extrusion members are provided and the multiple extrusion members are evenly arranged around a first vertical axis; and a movable member, which is coaxially arranged with the first vertical axis, wherein the movable member is located between the multiple extrusion members and the movable member abuts against the side of the extrusion members facing the first vertical axis.

[0023] To make the objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1

[0026] See Figure 1The main technical content of the first specific embodiment is shown. In the first embodiment, the technical solution includes a hook assembly 100, which includes a pressing member 101 and a moving member 102.

[0027] It is worth noting that during the lifting process, the wheel hub is generally placed flat on a horizontal surface, with the circumference of the wheel hub perpendicular to the horizontal surface. This facilitates lifting and subsequent procedures.

[0028] Specifically, the hook assembly 100 includes an extrusion member 101, which is located inside the hub during use. One end of the extrusion member 101 rotates around a first horizontal axis X1, while the other end of the extrusion member 101 gradually comes into contact with the inner circumferential wall of the hub during its rotation. Multiple extrusion members 101 are provided, evenly arranged around a first vertical axis Y1; in this embodiment, three extrusion members 101 are provided.

[0029] Preferably, the movable member 102 is coaxially arranged with the first vertical axis Y1, the movable member 102 is located between the plurality of extrusion members 101, and the movable member 102 abuts against the side of the extrusion members 101 facing the first vertical axis Y1. In this embodiment, the shape of the movable member 102 is not limited, and it can be disc-shaped, fan-shaped, or other shapes.

[0030] The movable part 102 can move along the direction of the first vertical axis Y1. Under the push of the movable part 102, the distance between the three extrusion parts 101 and the first vertical axis Y1 increases or decreases synchronously, ensuring that the three extrusion parts 101 move synchronously. The three extrusion parts 101 work together to stably grip the wheel hub, avoiding uneven force on the wheel hub and causing it to fall off. Example 2

[0031] See Figure 1 and Figure 2 The main technical content of the second specific implementation is shown. This embodiment is based on embodiment 1.

[0032] Specifically, it also includes a mounting component 103, which is coaxially arranged with the first vertical axis Y1. The mounting component 103 is used to install the extrusion component 101, wherein one end of the extrusion component 101 that rotates around the first horizontal axis X1 is disposed on the mounting component 103, and the end of the extrusion component 101 that rotates around the first horizontal axis X1 is rotatably connected to the mounting component 103.

[0033] Preferably, the extrusion member 101 includes a main body rod 101a and an extrusion rod 101b. The top end of the main body rod 101a is rotatably connected to the mounting member 103. The extrusion member 101 is disposed at the bottom end of the main body rod 101a. The distance between the outer edge of the extrusion rod 101 and the first vertical axis Y1 is greater than the distance between the main body rod 101a and the first vertical axis Y1. When the extrusion member 101 is pushed and rotated by the moving member 102, the extrusion rod 101b contacts the inner circumferential wall of the hub before the main body rod 101a.

[0034] Preferably, it also includes a first driving member 104. In this embodiment, the first driving member 104 is a cylinder. The output shaft of the first driving member 104 is coaxially arranged with the first vertical axis Y1. The moving member 102 is arranged on the output shaft of the first driving member 104. The output shaft of the first driving member 104 can move along the direction of the first vertical axis Y1, thereby driving the moving member 102 to move along the direction of the first vertical axis Y1. Example 3

[0035] See Figures 1-4 The main technical content of the third specific embodiment is shown, and this embodiment is based on embodiment 1. This embodiment provides a high-efficiency and stable lifting tool.

[0036] Preferably, the system includes an adjustment component 200, which includes a second driving component 201. In this embodiment, the second driving component 201 is a rotary cylinder. The mounting component 103 is provided with a sliding rod 103a, which moves along the second horizontal axis X2. The output end of the second driving component 201 is connected to the sliding rod 103a. The output end of the second driving component 201 can pull the sliding rod 103a to slide along the direction of the second horizontal axis X2, thereby pulling the hook assembly 100 to slide along the direction of the second horizontal axis X2.

[0037] Preferably, the adjustment assembly 200 further includes a rotating member 202 and a transmission member 203. The rotating member 202 rotates around the second vertical axis Y2. The rotating member 202 is disposed on the output shaft of the second driving member 201. The output shaft of the second driving member 201 first drives the rotating member 202 to rotate around the second vertical axis Y2. Then, since one end of the transmission member 203 is rotatably connected to the rotating member 202 and the other end is rotatably connected to the sliding rod 103a, the sliding rod 103a can be pulled to slide along the direction of the second horizontal axis X2.

[0038] Furthermore, multiple hook assemblies 100 are provided; in this embodiment, four hook assemblies 100 are provided, and the multiple hook assemblies 100 are evenly arranged around the second vertical axis Y2. The purpose of providing four hook assemblies 100 is to simultaneously lift four wheel hubs of the same size, and the purpose of providing the adjustment assembly 200 is to adjust the distance between the four hook assemblies 100 to accommodate wheel hubs of different sizes. When some wheel hubs are larger, the four hook assemblies 100 need to be adjusted outward to avoid insufficient space between the four hook assemblies 100.

[0039] Furthermore, the projection point of the first vertical axis Y1 onto the horizontal plane is concentric with the projection point of the second vertical axis Y2 onto the horizontal plane. This arrangement allows the four hook assemblies 100 to move synchronously in the direction of the second vertical axis Y2.

[0040] Furthermore, it also includes a frame 300, on which a sliding sleeve 301 is provided. The sliding sleeve 301 is used to install the sliding rod 103a, and the sliding rod 103a is slidably connected to the sliding sleeve 301.

[0041] Furthermore, the frame is provided with lifting rings 400, with at least two lifting rings 400, and in this embodiment, four lifting rings 400 are provided. The distance between the four lifting rings 400 and the second vertical axis Y2 is equal. This arrangement makes it less likely for the lifting device to tilt during lifting.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
