Description

Technical Field

[0001] The utility model relates to the technical field of vehicle manufacturing, in particular to a hoisting tool and a hoisting system. Background Art

[0002] In the field of vehicle manufacturing, the hoisting of the steering gear is an indispensable and important link in the production and assembly process. As one of the core components of the vehicle control system, the steering gear undertakes the key function of steering operation and is a key component of the vehicle's front wheel steering. It is responsible for converting the driver's steering operation into the rotation of the vehicle's front wheels, thereby changing the direction of the vehicle. Generally speaking, the steering gear usually includes components such as the steering column, steering rack, steering pin, and steering linkage. Its working principle is that the driver controls the steering column, so that the steering rack inside the steering gear produces corresponding movement, which is finally transmitted to the wheels, causing the vehicle to produce steering movement. The steering gear directly affects the vehicle's handling performance and safety. Therefore, ensuring the safe and efficient hoisting of the steering gear is a vital link in the vehicle manufacturing process.

[0003] However, the traditional steering gear hoisting process has a series of challenges and problems, which brings many difficulties to production and assembly. First, the steering gear itself has considerable weight and volume, and traditional hoisting methods such as hooks and slings have the problem of low hoisting efficiency. In this case, the hoisting operation requires more manpower and time, which reduces production efficiency. Secondly, due to the special structure of the steering gear, traditional hoisting tools are difficult to combine with it, which easily leads to safety hazards such as unstable and shaking hoisting points, further increasing the risks and uncertainties in the production process.

[0004] In current production practice, there are no dedicated lifting devices available for the two key processes of the steering gear body from the logistics equipment to the sub-packaging fixture, and the sub-packaging steering gear assembly from the sub-packaging fixture to the conveyor line pallet. Operators can only rely on simple tools such as hooks and slings to lift the steering gear body and the sub-packaging steering gear assembly, resulting in low lifting efficiency, unstable lifting process, and even the risk of falling and injuring the operator.

[0014] In one of the embodiments, the thickness of the loading component is 15 mm, and the surface of the loading component is heat treated.

[0015] In one embodiment, the fastener is a butterfly clasp.

[0016] The present application also provides a lifting system, comprising the above-mentioned lifting tool, lifting equipment and parts to be lifted.

[0032] See also Figure 1 An embodiment of the utility model provides a lifting tool, including a lifting component 100 and a loading component 200 connected to each other, the lifting component 100 includes a lifting structure 110 for connecting the lifting equipment, and a connecting structure 120 for connecting the lifting structure 110 and the loading component 200; the loading component 200 includes a first structure 210, a second structure 220 and a third structure 230, the first structure 210 is provided with a connecting hole 211 adapted to the connecting structure 120, the third structure 230 is provided with a hook 231 for lifting the steering gear assembly, and the second structure 220 is used to connect the first structure 210 and the third structure 230; wherein the first structure 210, the second structure 220 and the third structure 230 together enclose a receiving cavity, and the receiving cavity is suitable for clamping the protrusion of the steering gear body.

[0033] In this embodiment, the hook 231 on the third structure 230 is specifically used to lift the through hole on the connecting bracket of the steering gear assembly after assembly, and the first structure 210, the second structure 220 and the third structure 230 together enclose a receiving cavity for clamping the spline part of the steering gear body. Regardless of whether it is a light-load lifting tool or a heavy-load lifting tool, the spline part of the steering gear body is clamped by the receiving cavity, and is blocked by the outermost bolts of the spline to ensure the stability of the clamping. Therefore, the lifting tool provided in this embodiment can realize the lifting of different workpieces to be hoisted, and provides a reliable solution for the lifting of various workpieces to be hoisted. The first structure 210, the second structure 220 and the third structure 230 enclose a receiving cavity. This design provides a space specifically for accommodating the steering gear body. Through the formation of the receiving cavity, the steering gear body can be effectively fixed and protected, and unnecessary swinging and collision can be reduced during the lifting process, thereby improving the lifting efficiency and safety.

[0034] See also Figure 2 In one embodiment, the connection structure 120 includes at least two fasteners 121, the connection holes 211 are arranged corresponding to the fasteners 121, and the fasteners 121 penetrate the connection holes 211 and the lifting structure 110. By adopting at least two fasteners 121, the connection holes 211 and the fasteners 121 are arranged correspondingly, and multi-point connection is achieved. Compared with a single connection point, multi-point connection can provide a more stable connection, disperse the force during the lifting process, reduce the shaking and vibration during the lifting process, and improve the safety of the lifting tool. The connection holes 211 and the fasteners 121 are arranged correspondingly, ensuring the precise matching between the connection holes 211 and the fasteners 121. This design can effectively avoid offset or dislocation during connection, ensure the firmness and stability of the connection, and improve the reliability of the lifting tool. The fasteners 121 penetrate the connection holes 211 and the lifting structure 110, making the connection structure 120 more compact and strong. This design can reduce the number of connecting parts, simplify the structure of the lifting tool, and at the same time improve the strength and durability of the connecting structure 120, reducing maintenance costs and risks. Due to the design of the ring fastener 121, the lifting tool can be quickly installed and disassembled. It is only necessary to pass the ring fastener 121 through the connecting hole 211 and fix it on the lifting structure 110 to complete the assembly of the lifting tool, and when disassembling, it is only necessary to simply remove the ring fastener 121, saving time and labor costs. It should be noted that in the present embodiment, the number of the ring fastener 121 and the connecting hole 211 are both two, but the present application does not specifically limit the number of the ring fastener 121 and the connecting hole 211, so as to achieve a stable connection and fixing effect.

[0035] See also Figure 3 and Figure 4In one of the embodiments, the hook 231 and the plane where the end face of the third structure 230 is located facing the accommodating cavity are arranged at 105°. In order to ensure the stability of the clamped steering gear body, the overall dimensions of the accommodating cavities of the light-load lifting tool and the heavy-load lifting tool are kept consistent, so that the lifting tool can be suitable for lifting requirements under different load conditions, thereby improving the versatility and scope of application of the lifting tool. The connection angle of 105° helps the accommodating cavity to easily extend into the spline part of the steering gear body, ensuring a firm connection during the lifting process and improving the stability and safety of the lifting. The connection angle is taken into consideration in the design, so that the accommodating cavity can be blocked by the bolts on the outside of the spline when docking with the spline part of the steering gear body, thereby ensuring a smooth clamping and avoiding shaking and instability during the lifting process.

[0036] See also Figure 3 In one embodiment, the hook 231 is arranged at 90° to the plane where the end face of the third structure 230 is located away from the accommodating cavity. The position of the axis of the hook 231 and the third structure 230 is set at 90°, which is suitable for light load lifting conditions. This design scheme is more conducive to achieving precise docking between the hook 231 and the through hole on the connecting bracket under light load conditions, ensuring stability and safety during the lifting process. Since the axis of the hook 231 is arranged at 90° to the plane where the end face of the third structure 230 is located away from the accommodating cavity, the hook 231 can obtain a greater penetration depth when penetrating into the through hole on the connecting bracket. This design can ensure close contact between the hook 231 and the connecting bracket, increasing the stability and safety of the lifting.

[0037] See also Figure 4 In one embodiment, the hook 231 is arranged at 130 degrees to the plane where the end surface of the third structure 230 away from the accommodating cavity is located.

[0038] See also Figure 4In one embodiment, the connection between the hook 231 and the third structure 230, and the connection between the third structure 230 and the second structure 220 are both connected by an arc transition with a radius of 20 mm. The angle between the axis of the hook 231 and the third structure 230 is set to 130°, and an arc transition with a radius of 20 mm is used for heavy-load lifting conditions. This design can provide a stronger load-bearing capacity, ensure safety and stability during the lifting process, and is suitable for scenes with higher requirements for lifting tools. The 130° setting and the arc transition connection can optimize the structural layout of the lifting tool. This design makes the lifting tool more sturdy and stable, reduces the stress concentration of the structure, and helps to improve the overall load-bearing capacity and durability. By setting an angle of 130° and using an arc transition with a radius of 20 mm, it is possible to save materials to the greatest extent while ensuring the load-bearing capacity of the lifting tool. This design not only ensures the structural strength of the lifting tool, but also controls its weight, achieving the optimization of material use. The use of arc transition connection can effectively reduce stress concentration and wear between the hook 231 and the third structure 230, and between the third structure 230 and the second structure 220. This design can extend the service life of the lifting tool and reduce maintenance costs.

[0039] See also Figure 3 and Figure 4 In one embodiment, the diameter of the hook 231 along the direction of its axis away from the third structure 230 gradually decreases; or the diameter of the hook 231 along the direction of its axis remains unchanged. In this embodiment, the diameter of the hook 231 along the direction of its axis away from the third structure 230 gradually decreases, that is, the hook 231 is conical, which is more conducive to penetrating into the through hole on the connecting bracket, and the penetration depth is higher; the diameter of the hook 231 along the direction of its axis remains unchanged, that is, the hook 231 is truncated cone-shaped, which is more difficult to penetrate into the through hole on the connecting bracket than the conical shape, and the penetration depth is lower, but the truncated cone-shaped hook 231 has a larger diameter and higher strength. The conical and truncated cone-shaped hooks 231 are respectively suitable for light load conditions and heavy load conditions.

[0040] In one embodiment, the thickness of the loading assembly 200 is 15 mm, and the surface of the loading assembly 200 is heat treated. Through heat treatment, the material properties of the loading assembly 200 can be improved, and its hardness and strength can be increased. This is particularly important for lifting tools, because they need to withstand the pressure and tension of heavy objects. The higher the hardness and strength of the loading assembly 200, the better its durability and safety. A hardened layer is usually formed on the surface after heat treatment, and this hardened layer has good wear resistance. During the lifting process, the surface of the loading assembly 200 may be subjected to friction and wear. Through heat treatment, the surface wear can be reduced and the service life of the loading assembly 200 can be extended. Heat treatment can eliminate the internal stress and defects on the surface of the loading assembly 200, making its surface smoother and flatter. This is not only conducive to improving the appearance quality of the lifting tool, but also helps to reduce the damage and impact of surface defects on the loaded object, improve the safety and efficiency of the lifting process, and some heat treatment methods can also improve the corrosion resistance of the loading assembly 200, extend its service life in harsh environments, and reduce structural damage and safety hazards caused by corrosion.

[0041] In one embodiment, the ring fastener 121 is a butterfly buckle. The butterfly buckle is usually designed to be a structure that can be easily rotated and is easy to operate. Workers can quickly fix or remove the connecting component on the lifting structure 110 by manually rotating the butterfly buckle, saving installation and removal time and improving operating efficiency. The butterfly buckle provides a strong fixing force in the closed state to ensure that the connecting structure 120 is firm and stable. This design can prevent the loosening or falling off of the connecting component during the lifting process, thereby improving the safety of the lifting tool. As a common connecting component, the butterfly buckle has good versatility and can be applied to connecting holes 211 of various shapes and sizes. This design enables the lifting tool to be applicable to a variety of different lifting equipment and objects, thereby improving the flexibility and applicability of the lifting tool. The butterfly buckle is usually made of durable metal material and has higher strength and corrosion resistance after proper heat treatment. This design ensures that the butterfly buckle is not easily damaged when used for a long time in the lifting tool, thereby extending the service life of the lifting tool. The butterfly buckle usually adopts a hollow or lightweight design to reduce the weight of the connecting component and the weight of the lifting tool itself, thereby improving the convenience of handling and operation. It should be noted that the fastener 121 in this embodiment is a butterfly buckle, but the present application does not limit the specific structure and form of the fastener 121, and the buckling effect shall prevail.

[0042] An embodiment of the utility model further provides a hoisting system, comprising the above-mentioned hoisting tool, hoisting equipment and a part to be hoisted.

[0043] In this embodiment, the parts to be hoisted are the sub-assembled steering gear assembly and the steering gear body, and the parts to be hoisted include the sub-assembled steering gear assembly and the steering gear body, which are crucial components in the vehicle control system. The sub-assembled steering gear assembly is a steering gear component that has been assembled and sub-assembled, and has a certain degree of assembly completion; and the steering gear body is a key component for the front wheel steering of the vehicle, which is responsible for converting the driver's steering operation into the rotation of the front wheels of the vehicle, thereby changing the driving direction of the vehicle. The steering gear usually includes components such as a steering column, a steering rack, a steering pin, and a steering connecting rod. Its working principle is that the driver controls the steering column so that the steering rack inside the steering gear produces corresponding movement, which is finally transmitted to the wheels, so that the vehicle produces steering movement. Steering gears can be divided into many types according to their different structures and working principles. The design of the hoisting system is to improve the hoisting efficiency and safety of the steering gear. By introducing special hoisting tools and lifting equipment, accurate and stable hoisting of the hoisted parts can be achieved. The design of the hoisting tool takes into account the special structure and weight of the steering gear, ensuring a firm connection and stability during the hoisting process. The lifting equipment provides the necessary power support and operating platform, making the lifting process more convenient and safer.

[0044] The operation process of the entire lifting system includes hanging the lifting tool on the lifting equipment, operating the lifting equipment for lifting, placing the parts to be lifted to the target position, and then releasing the lifting device to complete the lifting process. Through this operation process, the steering gear assembly and the steering gear body can be lifted efficiently and safely, improving the efficiency and quality of the production assembly process.

[0045] The operation process of the hoisting system in this embodiment is as follows:

[0046] S1, hang the hoisting assembly 100 on the connection of the lifting equipment;

[0047] S2. Operate the lifting equipment and clamp the spline of the steering gear body with the accommodation cavity of the lifting equipment;

[0048] S3. Operate the lifting equipment to lift the steering gear body and place it on the steering gear subassembly fixture.

[0051] S6. Operate the lifting equipment to lift the assembled steering gear assembly and place it on the steering gear conveyor line pallet. After it is placed stably, loosen the lifting device to disengage the hook 231 from the connecting bracket, and then remove the lifting tool.

[0052] Through the above operation process, this hoisting system can effectively realize the hoisting operation of the steering gear body and the assembled steering gear assembly, ensure the stability and safety of the hoisting process, and improve production efficiency and operational convenience.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
