Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to a novel plate-type lifting lug for oversized and overweight horizontal containers. Background Technology

[0002] During the relocation of large equipment, lifting equipment is often required, and lifting lugs need to be installed on the equipment as the points of application for the lifting equipment. Due to the needs of production transfer, process transportation, and on-site installation, horizontal pressure vessels also require lifting lugs. For heavier pressure vessels, plate-type lifting lugs are often used for hoisting. Traditionally, plate-type lifting lugs are directly welded to the pressure vessel. Because pressure vessels have different hoisting requirements at different stages, when the tension applied by the lifting ropes to the lifting lugs is not along the length of the lugs, an imbalance occurs, causing the lugs to be pulled at an angle, posing a safety hazard. Therefore, higher requirements are placed on the strength of the lifting lugs themselves and the strength of the welds between the lugs and the pressure vessel. Utility Model Content

[0041] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0042] Please refer to Figure 1 This invention provides an embodiment of a novel plate-type lifting lug for oversized and overweight horizontal containers, comprising a fixed base 200, an adapter base 300, and a lifting lug 400. The fixed base 200 is directly fixed to the outer wall of the container body 100. The lifting lug 400 is detachably connected to the fixed base 200 via the adapter base 300. By replacing different adapter bases 300, the relative state between the lifting lug 400 and the container body 100 can be adjusted to meet different lifting conditions, ensuring that the force direction of the lifting lug 400 is adapted to its own structure, preventing damage to the lifting lug 400, and ensuring the stability and safety of the container body 100 during lifting.

[0043] To facilitate the replacement of the lifting lug 400, the fixing base 200 and the adapter base 300 are connected by a snap-fit ​​method. For example, as shown... Figure 2 As shown, the inner surface 203 of the fixing seat 200 fits against the outer wall of the container body 100, and the shape of the inner surface 203 is set according to the contour of the outer wall of the container body 100. The container body 100 is generally cylindrical, therefore, the inner surface 203 is preferably cylindrical. The fixing seat 200 is provided with a recessed snap-fit ​​groove 201 and a first connecting hole 202. The snap-fit ​​groove 201 is set away from the inner surface 203, so that the assembly and connection of the fixing seat 200, the container body 100, and the adapter 300 do not interfere with each other and have no influence on each other. For example, the fixing seat 200 has a cube-like structure with six sides, one of which is the inner surface 203 that fits and connects with the container body 100, and the snap-fit ​​groove 201 is provided on any one of the other five sides; preferably, the snap-fit ​​groove 201 is located on the side of the fixing seat 200 away from the container body 100.

[0044] The fixed base 200 is provided with a plurality of first connecting holes 202, which are arranged adjacent to the snap-fit ​​groove 201. The adapter 300 is slidably connected to the snap-fit ​​groove 201 and connected to the first connecting holes 202 by screws, bolts or other connecting parts, thereby fixing the adapter 300 on the fixed base 200. For example, there are two first connecting holes 202, which are symmetrically arranged with respect to the snap-fit ​​groove 201.

[0045] Furthermore, the snap-fit ​​groove 201 is a through groove, meaning that both ends of the snap-fit ​​groove 201 are open on both sides of the fixing base 200 along its length, facilitating assembly and disassembly. Preferably, the snap-fit ​​groove 201 is a dovetail groove, which can limit the position of the adapter base 300 in multiple directions.

[0046] like Figure 1 and Figure 3 As shown, the lifting lug 400 is provided with a snap-fit ​​hole 403, a lifting hole 402, and a second connecting hole 401; wherein, the snap-fit ​​hole 403 is used to snap and position with the adapter 300; the lifting hole 402 is used to connect the lifting equipment; and the second connecting hole 401 is used to fix the lifting lug 400 and the adapter 300, and the lifting lug 400 and the adapter 300 are fixedly connected by a connector located in the second connecting hole 401.

[0047] Please refer to Figure 1 , Figure 4 , Figure 5 The adapter 300 includes a connector 310, a snap-fit ​​body 320, and a connecting ear 330, which are fixedly connected as a single unit, or can be a single structure. The connector 310 connects to the lifting lug 400, the snap-fit ​​body 320 engages with the snap-fit ​​groove 201, and the two can slide into or out of a snap-fit ​​state; the connecting ear 330 fixes the adapter 300 to the fixed base 200. The snap-fit ​​body 320, adapted to the snap-fit ​​groove 201, is dovetail-shaped. There are two connecting ears 330, located on opposite sides of the snap-fit ​​body 320 along its length. A fourth connecting hole 331 is machined on the connecting ear 330, corresponding to the first connecting hole 202. Bolts, screws, and other connectors pass through the fourth connecting hole 331 and are fixedly connected to the first connecting hole 202.

[0048] The connector 310 has at least one connecting surface 312, on which a positioning block 311 and a third connecting hole 313 are provided; wherein, the positioning block 311 is used to cooperate with the snap-fit ​​hole 403 of the lifting lug 400 to snap and position the lifting lug 400, and the third connecting hole 313 is used to fix the lifting lug 400.

[0049] As a first embodiment of the adapter 300, please refer to Figure 1 , Figure 4-7 The connector 310 has a connecting surface 312. After the adapter 300 is installed on the container body 100, the connecting surface 312 is parallel to the length direction of the container body 100 and has a certain angle relative to the vertical direction, so that the upper part of the connecting surface 312 is inclined towards the inside of the container body 100. After the lifting lug 400 is connected to the adapter 300, the lifting lug 400 is close to the connecting surface 312, and the upper end of the lifting lug 400 also extends inclined towards the inside of the container body 100, which is suitable for the working condition of lifting the container body 100 at an angle.

[0050] As a second embodiment of the adapter 300, please refer to Figure 8-11 Unlike the first embodiment, after the adapter 300 is installed on the container body 100, the connecting surface 312 extends vertically and is parallel to the length direction of the container body 100; the lifting lug 400 is close to the connecting surface 312 and also extends vertically, which is suitable for vertically lifting the container body 100.

[0051] Positioning block 311 and snap-fit ​​hole 403 can be used as follows Figure 11 The structure shown is such that the positioning block 311 is cylindrical and there are three of them, and the snap-fit ​​hole 403 is a round hole and there are also three of them; after the positioning block 311 and the snap-fit ​​hole 403 are snapped together in sequence, the lifting lug 400 can be limited.

[0052] Preferably, the positioning block 311 and the snap-fit ​​hole 403 have multiple snap-fit ​​positions, allowing the lifting lug 400 to remain positioned even after rotating relative to the positioning block 311 by a set angle, thereby adjusting the lifting angle of the lifting lug 400 according to the actual application environment. For example, please refer to... Figures 1-11 The positioning block 311 is a regular hexagonal prism; the snap-fit ​​hole 403 is a regular hexagonal hole. There is only one positioning block 311 and one snap-fit ​​hole 403, allowing for six different connection positions between the positioning block 311 and the snap-fit ​​hole 403. This ensures that the length direction of the lifting lug 400 is consistent with the lifting direction of the hoisting rope, and that the lifting lug 400 has good stress-bearing performance. To ensure a reliable connection between the adapter 300 and the lifting lug 400, multiple third connection holes 313 are provided, and these holes are spaced apart on a circumference centered on the positioning block 311 at equal intervals. This ensures that the lifting lug 400 can still correspond one-to-one with the position of the second connection hole 401 after rotating a certain angle.

[0053] Alternatively, the positioning block 311 can be a regular triangular prism; the snap-fit ​​hole 403 can be an equilateral triangular hole; or the cross-sections of the positioning block 311 and the snap-fit ​​hole 403 can be regular polygons such as squares or regular pentagons.

[0054] Several evenly distributed teeth can also be provided on the peripheral sidewall of the positioning block 311 to form a gear shape; the inner wall of the snap-fit ​​hole 403 is also set as a gear ring shape, and the positioning block 311 and the snap-fit ​​hole 403 cooperate to form multiple connection positions. However, given that the position and state accuracy requirements of the lifting lug 400 are not high in actual applications, 3 to 6 connection positions between the positioning block 311 and the snap-fit ​​hole 403 are sufficient to meet most operating conditions.

[0055] By utilizing different adapters 300, the direction of the sling can be aligned with the length direction of the lifting lug 400. The lifting lug 400 has high tensile strength, ensuring stable and safe lifting of the container body 100. For example, the lifting lug 400 can be rotated to a specific angle as needed, and users can achieve single-point lifting using the special slings provided by the manufacturer. Before transferring the container body 100 within the manufacturing plant and lifting it, the adapter 300 can be replaced so that the lifting lug 400 is located in the vertical plane, allowing the use of overhead cranes within the plant for lifting.

[0056] For the same adapter 300, more than one connection surface 312 can be provided. Of course, each connection surface 312 is provided with a positioning block 311 and a third connection hole 313. In this way, the adapter 300 can be used in a variety of working conditions, and the utilization rate is greatly improved.

[0057] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
