Description

Technical Field

[0001] The utility model relates to the technical field of hoisting tackle equipment, and particularly relates to a novel hoisting tooling. Background Art

[0002] In the processing industry of steel plate surfaces, enterprises usually purchase steel coils as raw materials, and then perform surface treatment on the steel coils through a production process line. After the treatment is completed, the steel plates are coiled into steel coils again and then subjected to subsequent handling and processing. However, during the process of unloading the steel coils when they enter the factory and handling them after processing, due to the large weight of the steel coils, traditional manual operation is not only laborious and time-consuming, but also inefficient. In the industry, a hoisting system combining a hook and an electric hoist is generally used, and through a mechanized method, the hoisting and handling of steel coils can be easily and quickly completed, thereby saving labor and improving the handling efficiency.

[0003] Traditional steel coil hoisting tools include an upper cross beam, a connecting arm and a lower cross beam. The upper cross beam, the connecting arm and the lower suspension beam are vertically connected. Although the structure is simple, when facing steel coils with large weights and different sizes, its structural strength and stability are often challenged, and there are certain potential safety hazards. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a novel hoisting tooling. By designing the connecting arm into a semi-circular shape, the overall structural strength and load-bearing capacity of the hoisting tool are improved, and the stability and safety during the hoisting process are optimized.

[0005] To achieve the above purpose, the embodiments of the utility model adopt the following technical solutions:

[0006] A novel hoisting tooling, comprising:

[0007] An upper cross beam, which is of I-shaped steel structure. The upper cross beam includes a first outer flange, a first inner flange and a first web, and the first outer flange, the first inner flange and the first web are integrally formed;

[0008] A lower suspension beam, which is of I-shaped steel structure. The lower suspension beam includes a second outer flange, a second inner flange and a second web, and the second outer flange, the second inner flange and the second web are integrally formed;

[0009] A connecting arm, which is composed of a semi-circular steel plate and an edge plate vertically connected to the outer arc of the steel plate, and the edge plate and the steel plate are integrally formed; the upper cross beam and the lower suspension beam are respectively connected to the corresponding positions of the connecting arm by welding;

[0010] A number of reinforcing ribs, including vertical reinforcing ribs and horizontal reinforcing ribs. The horizontal reinforcing ribs are arranged at the welded joints of the upper cross beam and the connecting arm, and at the welded joints of the lower suspension beam and the connecting arm. The vertical reinforcing ribs are fixedly connected to the upper cross beam and the lower suspension beam respectively by welding.

[0011] In one embodiment, the steel plate is fixedly connected to the first web and the second web by welding.

[0012] In one embodiment, the upper end of the edge plate is connected to the first outer flange of the upper cross beam by welding, and the lower end of the edge plate is connected to the second outer flange of the lower suspension beam by welding.

[0014] In one embodiment, a lifting interface is further provided in the middle of the first outer flange of the upper cross beam for connecting lifting equipment.

[0015] The beneficial effect of the present utility model lies in providing a new type of lifting tooling, including an upper cross beam, a connecting arm, and a lower suspension beam.

[0023] As Figure 1 shown, a new type of lifting tooling includes an upper cross beam 1, a lower suspension beam 2, a connecting arm 3, and several reinforcing ribs.

[0024] The upper cross beam 1 is of I-beam steel structure. The upper cross beam 1 includes a first outer flange 11, a first inner flange 12, and a first web 13. Among them, the first outer flange 11, the first inner flange 12, and the first web 13 are of an integrally formed structure, ensuring the strength and stiffness of the upper cross beam 1.

[0025] The lower suspension beam 2 is an I-beam structure, and the lower suspension beam 2 includes a second outer flange 21, a second inner flange 22 and a second web 23. The second outer flange 21, the second inner flange 22 and the second web 23 are also an integrally formed structure. The lower suspension beam 2 is used to carry and suspend the steel coil.

[0026] The connecting arm 3 is composed of a semicircular steel plate 31 and an edge plate 32 vertically connected to the arc-shaped outer side of the steel plate 31. The edge plate 32 and the steel plate 31 are an integrally formed structure, which enhances the integrity and stability of the connecting arm 3; the upper cross beam 1 and the lower suspension beam 2 are respectively connected to the corresponding positions of the connecting arm 3 by welding. Specifically, the steel plate 31 is fixedly connected to the first web 13 and the second web 23 by welding; the upper end of the edge plate 32 is connected to the first outer flange 11 of the upper cross beam 1 by welding, and the lower end of the edge plate 32 is connected to the second outer flange 21 of the lower suspension beam 2 by welding. The upper cross beam 1, the connecting arm 3 and the lower suspension beam 2 form a stable "C"-shaped structure. Holes can be opened on the steel plate 31 to reduce the weight of the material.

[0027] The connecting arm 3 of the "C" type structure is semicircular in shape. This shape can better disperse the force to the entire structure when subjected to vertical downward pressure, thereby reducing the risk of local stress concentration. In contrast, the right-angle connection of the traditional "匚" type structure may be more prone to stress concentration, resulting in a relatively weak structural strength. In the "C" type structure, due to the arc design of the connecting arm 3, materials can also be used more effectively, so that the entire structure requires less material when bearing the same weight, but has higher strength.

[0028] The reinforcing ribs include vertical reinforcing ribs 41 and transverse reinforcing ribs 4. The transverse reinforcing ribs 4 are arranged at the welded connection between the upper cross beam 1 and the connecting arm 3 and at the welded connection between the lower suspension beam 2 and the connecting arm 3. The vertical reinforcing ribs 41 are respectively fixedly connected to the upper cross beam 1 and the lower suspension beam 2 by welding. The reinforcing ribs are respectively fixedly connected to the upper cross beam 1, the lower suspension beam 2 and the connecting arm 3 by welding, which further enhances the strength and stability of the connection.

[0029] In actual application, the upper cross beam 1, the lower suspension beam 2, and the connecting arm 3 are all made of high-strength steel to ensure that the sling tooling is not easily deformed or damaged when bearing heavy loads, thereby improving the overall safety and reliability. In this embodiment, Q345B low-alloy high-strength structural steel can be selected as the main material. This material has good comprehensive mechanical properties and welding properties, and can meet the use requirements of the sling tooling in a high-intensity working environment. The welding of each component is carried out using standard welding processes and equipment to ensure that the weld quality meets the relevant standard requirements. During the welding process, the welding parameters and welding sequence are strictly controlled to avoid the occurrence of welding defects and ensure the overall quality of the sling tooling.

[0030] In practical applications, it further includes a lifting interface 5 provided in the middle of the first outer flange 11 of the upper cross beam 1 for connecting a lifting device to realize the lifting operation of the steel coil.

[0031] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the scope of the present invention patent.

[0032] In order to enable those of ordinary skill in the art to more conveniently understand the improvements of the present invention over the prior art, some of the drawings and descriptions of the present invention have been simplified. For the sake of clarity, some other elements have also been omitted in this application document. Those of ordinary skill in the art should be aware that these omitted elements may also constitute the content of the present invention.
