Abstract
Description
A compressor base that is easy to hoist Technical Field
[0001] This utility model relates to the field of compressor hoisting technology, specifically to a compressor base that is easy to hoist. Background Technology
[0002] In high-pressure gas industrial production, centrifugal compressors are widely used due to their wide pressure range and large flow characteristics. Their base serves as a support structure for core components such as the casing and motor. During the overall transportation of the equipment, lifting operations are carried out using lifting lugs welded to the sides of the I-beams that make up the base.
[0003] However, as a single stress point, the lifting lugs bear the entire weight of the compressor. When the equipment is heavy, local plastic deformation of the lifting lugs is likely to occur. This deformation not only directly weakens the structural integrity of the base, but may also cause the overall deformation of the base through the transmission of the I-beams. This can then disrupt the original alignment accuracy between the compressor spindle and the motor spindle, resulting in a chain reaction of technical defects that exacerbate equipment vibration and reduce mechanical efficiency, seriously threatening the safe and stable operation of the compressor unit. Summary of the Invention
[0004] The purpose of this utility model is to provide a compressor base that is easy to hoist. By setting square steel reinforcements below the gearbox and main motor placement positions, and using a hoisting crossbar to pass through the square steel reinforcements, the hoisting force is transmitted as a whole through the square steel reinforcements located directly below the load-bearing parts of the compressor and the hoisting crossbar. This transforms the point load of the original lifting lugs into a surface load, resulting in more uniform force distribution and a larger force distribution area. The main body of the base is also less prone to deformation and scrapping.
[0005] To achieve the above objectives, this utility model provides a compressor base that is easy to hoist, comprising:
[0006] The base body has gearbox placement positions and main motor placement positions respectively provided on both sides of the base body;
[0007] A square steel reinforcement component is provided along the width direction of the base body at the gearbox placement position and the main motor placement position;
[0008] A lifting crossbar is replaceably installed inside the square steel reinforcement, with both ends of the lifting crossbar extending through the square steel reinforcement to both sides of the base body. Lifting components are correspondingly provided at both ends of the lifting crossbar.
[0009] Optionally, there is a set of square steel reinforcements at the gearbox placement position and the main motor placement position, and there is at least one square steel reinforcement in each set. At least one square steel reinforcement in the same set is distributed at intervals along the length direction of the base body.
[0010] Optionally, a number of connectors are provided between two adjacent square steel reinforcement members in the same group.
[0011] Optionally, the base body is formed by splicing and welding several I-beams, and the square steel reinforcement has the same size as the I-beams, and the square steel reinforcement is welded to the base body.
[0012] Optionally, a fixing pin is provided between the square steel reinforcement and the lifting crossbar disposed within the square steel reinforcement for fixing.
[0013] Optionally, the lifting component is a lifting lug or a lifting hook.
[0014] The beneficial effects of this utility model are as follows: By setting square steel reinforcements below the gearbox and main motor placement positions, and using a lifting crossbar to penetrate the square steel reinforcements, the lifting force is transmitted as a whole through the square steel reinforcements located directly below the compressor's load-bearing part and the lifting crossbar. This transforms the point load of the original lifting lugs into a surface load, resulting in more uniform force distribution and a larger load-bearing surface, making the base body less prone to deformation and scrapping. By setting the lifting crossbar as the main load-bearing component, under overload conditions, the detachable and replaceable lifting crossbar is the first to deform rather than the base body, which improves economy and maintenance convenience.
[0015] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0018] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0019] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0021] Please refer to Figure 1. A preferred embodiment of this application shows a compressor base that is easy to hoist, comprising a base body 1, a square steel reinforcement 2, and a hoisting crossbar 3. Gearbox placement positions 11 and main motor placement positions 12 are respectively provided on both sides of the base body 1. The square steel reinforcement 2 is arranged along the width direction of the base body 1 at the gearbox placement positions 11 and the main motor placement positions 12. The hoisting crossbar 3 is replaceably disposed within the square steel reinforcement 2, with both ends of the hoisting crossbar 3 extending through the square steel reinforcement 2 to both sides of the base body 1. Hoisting components are correspondingly provided at both ends of the hoisting crossbar 3.
[0022] According to the embodiment of this utility model, by setting a square steel reinforcement 2 below the gearbox placement position 11 and the main motor placement position 12, and then using a lifting crossbar 3 to penetrate the square steel reinforcement 2, the lifting force is transmitted as a whole through the square steel reinforcement 2 located directly below the compressor's load-bearing part, in conjunction with the lifting crossbar 3. This transforms the point load of the original lifting lug into a surface load, resulting in more uniform force distribution and a larger force-bearing surface, making the base body 1 less prone to deformation and scrapping. Setting the lifting crossbar 3 as the main load-bearing component ensures that under overload conditions, the detachable and replaceable lifting crossbar 3, rather than the base body 1, will deform first, improving economy and maintenance convenience. It should be noted that since the compressor gearbox and main motor are the heaviest components, placing the square steel reinforcement 2 directly below them provides the best load-bearing effect. Furthermore, because the force is transmitted as a whole through the lifting crossbar 3 and the square steel reinforcement 2, even if the compressor is too heavy, the lifting crossbar 3 will deform first. Therefore, the lifting crossbar 3 is made replaceable, which makes it easy to replace the lifting crossbar 3 instead of replacing the entire base body 1, thereby saving maintenance costs.
[0023] The following detailed description uses specific examples:
[0024] There is a set of square steel reinforcement members 2 at the gearbox placement position 11 and the main motor placement position 12, and there is at least one square steel reinforcement member 2 in each set. At least one square steel reinforcement member 2 in the same set is distributed at intervals along the length of the base body 1. By arranging multiple square steel reinforcement members 2 at intervals along the length of the base at the gearbox placement position 11 and the main motor placement position 12, the lifting load can be evenly distributed over a longer support area, avoiding concentrated stress.
[0025] Furthermore, several connectors are provided between two adjacent square steel reinforcement members 2 within the same group. These connectors, such as those made of transverse steel plates, angle steel, or bolts, connect the dispersed square steel reinforcement members 2 into a unified whole, forming a grid-like rigid frame. This prevents lateral displacement or torsion of individual square steel reinforcement members 2 due to uneven stress distribution. The connectors can guide load sharing between adjacent reinforcement members, especially suppressing stress fluctuations caused by vibration during dynamic lifting.
[0026] Please refer to Figure 1. The base body 1 is constructed by splicing and welding several I-beams. The square steel reinforcement 2 has the same dimensions as the I-beams and is welded to the base body 1. The design of the square steel reinforcement 2 being the same size as the I-beams ensures that their cross-sectional moments of inertia are matched, forming a continuous mechanical interface after welding and avoiding stress concentration caused by abrupt changes in stiffness. Using profiles with the same cross-section simplifies material preparation and processing (such as cutting and beveling), reducing manufacturing costs.
[0027] Furthermore, a fixing pin is provided between the square steel reinforcement 2 and the lifting crossbar 3 disposed within the square steel reinforcement 2 for fixing. The fixing pin can prevent the lifting crossbar 3 from sliding along its axial direction within the square steel reinforcement 2, ensuring the stability of the lifting crossbar 3 during the lifting process and avoiding center of gravity shift due to accidental displacement.
[0028] Specifically, in this embodiment, the lifting component is a lifting lug or a lifting hook.
[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.
[0030] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
