Description

Technical Field

[0001] This invention belongs to the field of lifting operation technology, specifically, it relates to a method for facilitating the attachment and detachment of rigging on a hook. Background Technology

[0002] In the field of lifting operations, hook attachment and detachment are the core operational steps for connecting lifting equipment to the load and transferring the load. The efficiency, safety, and convenience of this operation directly affect the overall work process. Currently, the industry's widely adopted hook attachment and detachment methods mainly rely on direct manual operation, with manpower allocation depending on the weight class of the rigging: for light rigging weighing no more than 0.05 tons, one operator can usually complete the hook attachment and detachment independently; while for medium and large rigging weighing more than 0.05 tons, two or more operators are generally required to work together to complete the task.

[0003] For scenarios involving the attachment and detachment of large rigging weighing over 0.05 tons, this traditional manual collaborative operation mode has gradually revealed several significant drawbacks in practice. Firstly, in terms of operational procedures, multi-person collaboration requires repeated communication and precise coordination among workers regarding their positioning, gripping points, and the timing and rhythm of force application. Any deviation in coordination can lead to operational inefficiencies, prolonging the time required for each attachment / detachment operation and impacting the overall work rhythm. Secondly, regarding labor and economic costs, each handling of large rigging requires at least two skilled workers, resulting in persistently high labor costs over time. This issue is particularly pronounced in situations with labor shortages or high operational frequency. Most importantly, this operational mode is physically demanding and carries significant safety risks. Large rigging is often heavy and bulky. When manually attaching or detaching it, personnel must operate it at close range under complex conditions such as hook swing and limited space. This not only puts enormous physical load on the workers, easily causing fatigue and reducing continuous work efficiency, but also poses a direct threat to personnel safety because the close contact between personnel and moving heavy objects makes them highly susceptible to accidents such as crushing or crushing injuries due to rigging swaying, slipping, or coordination errors.

[0004] Therefore, the existing method of detaching and attaching cranes, which relies on pure manual labor, is high-intensity, and has low safety, has become a major bottleneck restricting the improvement of lifting operation efficiency and safety production level. A more efficient, labor-saving, and safe innovative solution is urgently needed to improve it. Summary of the Invention

[0005] This invention addresses the technical problems of time-consuming and laborious rigging and detaching from lifting hooks, the large number of workers required for traditional rigging detachment and detachment methods, safety hazards, and low work efficiency. It provides a method for easily detaching and detaching rigging from lifting hooks. Compared to traditional rigging detachment and detachment methods, the effective cooperation of connecting structures and auxiliary ropes makes detaching and detaching heavier rigging from lifting hooks safer and less strenuous, ensuring operational safety and improving work efficiency.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention provides a method for easily attaching and detaching rigging from a hook, used to engage or disengage the rigging wire rope from the hook body; it utilizes a connecting structure and an auxiliary rope, the connecting structure being fixedly installed at the hook tip of the hook body, and the first end of the auxiliary rope being connected to the connecting structure; the method includes the processes of attaching and detaching the rigging from the hook:

[0008] The process of attaching rigging to the hook includes:

[0009] Position the hook body close to the ground, and prepare to hook the rigging wire rope into the hook body;

[0010] The second end and the middle section of the auxiliary rope are placed on the ground, and the rigging wire rope to be attached is placed on the middle section of the auxiliary rope, with the rigging wire rope and the auxiliary rope arranged in a crisscross pattern.

[0011] After connecting the second end of the auxiliary rope to the auxiliary tool, use the auxiliary tool to lift the second end of the auxiliary rope, and the auxiliary rope will drive the rigging wire rope to lift upward;

[0012] Continue to lift the second end of the auxiliary rope upwards using auxiliary tools until the rigging wire rope falls into the hook body along the auxiliary rope, thus enabling the rigging wire rope to be hooked into the hook body.

[0013] The process of removing the rigging from the hook includes:

[0014] Position the hook body close to the ground, with the rigging wire rope inside the hook body.

[0015] The second end of the auxiliary rope passes under the rigging wire rope, and the auxiliary rope and the rigging wire rope are arranged in a crisscross pattern.

[0016] After connecting the second end of the auxiliary rope to the auxiliary tool, use the auxiliary tool to lift the second end of the auxiliary rope, and the auxiliary rope will drive the rigging wire rope to lift upward;

[0017] Continue lifting the second end of the auxiliary rope using the auxiliary tool until the rigging wire rope passes over the hook tip of the hook body along the auxiliary rope, thus detaching the rigging wire rope from the hook body.

[0018] Furthermore, the connection structure is a circular ring structure.

[0019] Furthermore, the phrase "the hook body is located near the ground" means that the vertical distance between the lowest point of the hook body and the ground is 0-500mm.

[0020] Furthermore, the auxiliary tools are forklifts, excavators, or auxiliary cranes.

[0021] The beneficial effects of this invention are:

[0022] (i) The present invention is designed with a clever concept so that when detaching or attaching large rigging weighing more than 0.05 tons, only one operator is needed to complete the task independently and safely. This completely changes the mandatory requirement of two or more people in the traditional model, directly reduces the manpower input in a single operation and long-term operation, effectively saves labor costs, alleviates the dependence on specific skilled workers, and optimizes the allocation of human resources.

[0023] (ii) By eliminating the complex coordination steps such as communication, positioning, and synchronized force that are essential in multi-person collaborative operations, this invention greatly simplifies the operation process; operators can quickly and directly perform the detachment and attachment actions, significantly shortening the time for a single operation; the simplification and standardization of the process also reduces the high dependence on the collaborative experience of operators, thereby improving the overall continuity and rhythm of the operation and greatly improving the overall efficiency of lifting operations.

[0024] (III) This invention can systematically reduce operational risks from a technical perspective. On the one hand, by avoiding close cooperation among multiple people, it fundamentally eliminates safety hazards such as squeezing and collisions caused by communication errors and asynchronous force application. On the other hand, by optimizing human-machine interaction or introducing auxiliary labor-saving mechanisms, the operator does not need to directly bear the full load of the heavy object, which greatly reduces the physical exertion and labor intensity of the operators and reduces the possibility of misoperation caused by fatigue, thereby providing a higher level of safety protection for the operators.

[0031] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0032] This invention is specifically designed to solve the problem of attaching and detaching large rigging, and is specifically suitable for large rigging weighing > 0.05 tons. Its core design comprises two key components: first, a connecting structure 2 is installed on the hook body 1 to connect an auxiliary rope 3, thereby optimizing the attachment positioning and force transmission of the rigging wire rope 4; second, a dedicated auxiliary rope 3 for attaching and detaching is configured, reducing the difficulty of single-person operation through optimized mechanical transmission. Through the synergistic effect of these two design components, a revolutionary operational mode for attaching and detaching large rigging is achieved.

[0033] Generally, the hook body 1 for lifting operations includes an integrally formed hook shank, hook neck, hook body, and hook tip. The hook shank is located at the tail of the hook body 1 and usually has a hole or thread for connecting to the crane's wire rope, chain, or other connecting devices. The hook neck is the transition section between the hook shank and the hook body and needs to withstand a certain amount of tension. The hook body is the part connecting the hook tip and the hook neck, and is usually arc-shaped or straight, serving as the main structure of the hook and bearing the main tension. The hook tip is the very end of the hook, and its shape is usually sharper than the hook body to ensure that the object does not slip during lifting.

[0034] like Figure 1 As shown, the connecting structure 2 of the present invention is set at the hook tip of the hook body 1 and can be connected to the first end of the auxiliary rope 3. The auxiliary rope 3 is operated by the operator. The connecting structure 2, in conjunction with the force exerted by the auxiliary rope 3, assists in the hooking and unhooking of the rigging, reducing the force required for single-person operation. Only one operator is needed to complete the hooking and unhooking of large rigging, thus improving the efficiency and safety of lifting operations.

[0035] Specifically, the connecting structure 2 can be a ring structure such as a nut, and welded to the hook tip of the hook body 1. In use, one end of the auxiliary rope 3 is connected to the connecting structure 2. The auxiliary rope 3 is a conventional rope, sufficient to support the weight of the rigging wire rope 4.

[0036] The method for attaching rigging to a hook according to the present invention comprises the following steps:

[0037] like Figure 1 As shown, with the hook body 1 in an empty state, the hook body 1 is lowered to a height of 100mm above the ground. The first end of the auxiliary rope 3 is connected to the connecting structure 2, the second end and the middle section of the auxiliary rope 3 are placed on the ground, and the rigging wire rope 4 to be attached is placed on the middle section of the auxiliary rope 3. At this time, the rigging wire rope 4 and the auxiliary rope 3 are arranged in a crisscross pattern.

[0038] like Figure 2 As shown, the second end of the auxiliary rope 3 is connected to the auxiliary tool, and the auxiliary tool is used to lift the second end of the auxiliary rope 3. The auxiliary rope 3 will then drive the rigging wire rope 4 to lift upward.

[0039] The auxiliary tools can be forklifts, excavators, or auxiliary cranes (truck cranes).

[0040] like Figure 3 As shown, by using auxiliary tools to continue lifting the second end of the auxiliary rope 3, the rigging wire rope 4 will slide along the auxiliary rope 3 towards the first end of the auxiliary rope 3 under its own weight, that is, towards the hook tip of the hook body 1, until it detaches from the auxiliary rope 3 and falls into the hook body of the hook body 1.

[0041] The method for detaching slings from a hook according to the present invention is the complete opposite of the method for attaching slings, and the steps are as follows:

[0042] like Figure 4 As shown, the hook body 1 is lowered to a height of 100mm above the ground, the first end of the auxiliary rope 3 is connected to the connecting structure 2, and the second end of the auxiliary rope 3 is passed under the rigging wire rope 4. At this time, the rigging wire rope 4 and the auxiliary rope 3 are arranged in a cross configuration.

[0043] Connect the second end of the auxiliary rope 3 to the auxiliary tool, and use the auxiliary tool to lift the second end of the auxiliary rope 3. The auxiliary rope 3 will then drive the rigging wire rope 4 to lift upward.

[0044] like Figure 5 As shown, as the auxiliary rope 3 continues to be lifted, the rigging wire rope 4 will move to the hook tip of the hook body 1 and pass over the hook tip of the hook body 1, thus completing the separation of the rigging wire rope 4 from the hook body 1.

[0045] During the process of removing the rigging, the operator and the work should be kept away from the hook body 1.

[0046] It is evident that this invention specifically addresses the long-standing pain points of "time-consuming, labor-intensive, and high-risk" operations in conventional large-scale rigging and detachment, providing a more advanced, reliable, and practical technical option for the lifting operations field, and has high value for promotion and application.

[0047] The technical solutions disclosed and proposed in this invention can be implemented by those skilled in the art by appropriately modifying the conditions and routes, etc. Although the methods and preparation techniques of this invention have been described through preferred embodiments, those skilled in the art can obviously modify or recombine the methods and technical routes described herein without departing from the content, spirit, and scope of this invention to achieve the final preparation technique. It should be particularly noted that all similar substitutions and modifications are obvious to those skilled in the art and are considered to be included within the spirit, scope, and content of this invention.
