[0027] In the following description, numerous details are provided to facilitate a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, and that the present invention may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well known in the art have not been described in detail.

[0028] To thoroughly understand the embodiments of the present invention, a detailed structure will be provided in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0029] The present invention provides a mounting base in an embodiment. The mounting base can be used to mount a compression device, which can be mounted on the bottom of the compression device and placed on a fixed surface (such as the ground). Figure 2 and Figure 4 The mounting base 10 may include a main frame 110, a crossbeam assembly 120 and a plurality of mounting portions 130. The main frame 110 may include a first vertical beam 1110 and a second vertical beam 1120 that are relatively arranged. The first vertical beam 1110 and the second vertical beam 1120 may satisfy a parallel condition. It is understandable that the main frame 110 may also include other vertical beams, which are combined with the first vertical beam 1110 and the second vertical beam 1120 to form the main frame 110. The crossbeam assembly 120 may be connected between the first vertical beam 1110 and the second vertical beam 1120 and form a rotating member mounting position 1201 at the top of the crossbeam assembly 120. The rotating member mounting position 1201 may be used to install a rotating member. The crossbeam assembly 120 provides an installation space for the rotating member on the one hand, and can provide support for the rotating member on the other hand. The rotating member can be used to rotate the compression device. An installation area for installing the compression device can be formed between the multiple installation parts 130, wherein at least one of the multiple installation parts 130 can have an adjacent first side 13111 and a second side 13112, the first side 13111 is connected to the first vertical beam 1110 or the second vertical beam 1120, and the second side 13112 is connected to the crossbeam assembly 120. Preferably, there can be four installation parts 130, and each of the four installation parts 130 can have a first side 13111 and a second side. The first side 13111 and the second side 13112 can ensure the stability of the position of the installation part 130, that is, ensure the stability and installation of the compression device on the installation base 10. Of course, the other side edges of the installation part 130 can also be connected to other parts of the main frame 110 to better ensure the stability of the installation part 130.

[0030] It is understood that the mounting base 10 is required to support the weight of the compression device during use. In most cases, the mounting portion 130 bears this weight. During maintenance of the compression device, the rotating member needs to rotate the compression device. In this case, the weight of the compression device acts on the rotating member, which affects the structural strength of the crossbeam assembly 120.

[0031] The mounting base 10 provided in the present application has a mounting portion 130 connected to both the main frame 110 and the crossbeam assembly 120. The mounting portion 130 is more stable, that is, it provides a more stable installation and support for the compression device. A rotating member mounting position 1201 is provided on the crossbeam assembly 120, that is, a rotating member can be provided on the rotating member mounting position 1201 to realize the rotation of the compression device. In this way, by rotating the compression device to a predetermined angle, operations such as core pulling and maintenance can be realized on the side of the mounting base 10. Compared with the solution of lifting the compression device by a hoisting structure in the prior art, it is less difficult and more convenient to operate.

[0032] For example, with reference to Figure 2 and Figure 4 , part of the multiple mounting parts 130 can be located on the first side of the beam assembly 120 and another part can be located on the second side of the beam assembly 120, and the first side and the second side are opposite to each other. That is, the beam assembly 120 is located in the middle, and mounting parts 130 are respectively provided on both sides of the beam assembly 120. An installation area is formed between the multiple mounting parts 130, that is, when a compression device is installed in the installation area, the rotating part located on the rotating part mounting position 1201 can be in the middle of the compression device. In this way, it is easier for the rotating part to rotate the compression device, ensuring the smooth progress of the maintenance process. Preferably, the beam assembly 120 can be connected to the middle of the first vertical beam 1110 and the middle of the second vertical beam 1120, and the mounting parts 130 on both sides of the beam assembly 120 are symmetrically arranged. In an embodiment not shown, the multiple mounting parts can all be located on one side of the beam assembly, and the rotating part realizes the rotation of the compression device through other structural transmission.

[0033] For example, with reference to Figure 2 and Figure 5The crossbeam assembly 120 may include a top cross plate 1210, a bottom cross plate 1220, and a vertical cross plate 1230 connected between the top cross plate 1210 and the bottom cross plate 1220. The second side 13112 may be connected to the top cross plate 1210, and the rotating member mounting position 1201 may be formed at the top of the top cross plate 1210. The top cross plate 1210, the bottom cross plate 1220, and the vertical cross plate 1230 may be welded together. For example, the top cross plate 1210, the bottom cross plate 1220, and the vertical cross plate 1230 may not be made of conventional HN800X300X14X26L I-beams, but may be made of reinforced and thickened steel plates to better ensure the strength of the crossbeam assembly 120. The top cross plate 1210 may have a first end 1211 and a second end 1212 located on opposite sides of the rotating member mounting position 1201. The first end portion 1211 may extend to the top of the first vertical beam 1110 and may be connected to the top surface of the first vertical beam 1110, and / or the second end portion 1212 may extend to the top of the second vertical beam 1120 and may be connected to the top surface of the second vertical beam 1120. In other words, the first end portion 1211 contacts the top surface of the first vertical beam 1110, i.e., is supported by the first vertical beam 1110. The second end portion 1212 contacts the top surface of the second vertical beam 1120, i.e., is supported by the second vertical beam 1120, which can further enhance the stability of the crossbeam assembly 120. The first end portion 1211 may be welded to the first vertical beam 1110, and the second end portion 1212 may be welded to the second vertical beam 1120. Compared with the usual connection method, that is, the horizontal beam is directly connected to the sides of the two vertical beams, the mounting base 10 provided in this embodiment has an increase in the number of welding points between the top horizontal plate 1210 and the first vertical beam 1110 and the second vertical beam 1120 from one to three. More welding points can reduce the risk of weld tearing, the connection between the horizontal beam assembly 120 and the main frame 110 is more stable, and the mounting base 10 as a whole is more stable.

[0034] For example, with reference to Figure 5 、 Figure 6 and Figure 7 , a reinforcing rib 1240 is further connected between the top horizontal plate 1210 and the bottom horizontal plate 1220. Specifically, the reinforcing rib 1240 can be correspondingly arranged below the rotating part mounting position 1201. The mounting base 10 is made of steel material number Q235b, with an elastic modulus of 200GPa, a Poisson's ratio of 0.3, a density of 7850Kg / M3, and a yield strength of 225MPa. Based on the above steel material analysis, Figure 6 The stress distribution diagram of the mounting base 10 is shown. It can be concluded that the beam assembly 120 is subjected to a large stress, wherein the maximum stress reaches 148.6 MPa, which is less than the yield strength of the material 225 MPa. The strength meets the design requirements, and the safety factor is 1.52. Figure 7A diagram showing the vertical deformation of the mounting base 10 shows that the vertical deformation of the crossbeam assembly 120 is also significant, with the maximum vertical deformation (vertically downward) reaching 0.42 mm. In this embodiment, the provision of reinforcing ribs 1240 further enhances the strength of the crossbeam assembly 120, ensuring more stable support for the rotating member located above it, thereby ensuring safe and stable rotation of the compression device.

[0035] For example, with reference to Figure 2 and Figure 4 The mounting portion 130 may include a support plate assembly 1310, which includes a top plate 1311, a bottom plate 1312, and a vertical plate 1313 connected between the top plate 1311 and the bottom plate 1312. The first side 13111 and the second side 13112 may be formed at the edge of the top plate 1311. The thickness of the top plate 1311 and / or the bottom plate 1312 is 90 mm to 110 mm. For example, the thickness of the top plate 1311 and / or the bottom plate 1312 may be 90 mm, 100 mm, or 110 mm. Preferably, the thickness of the top plate 1311 and the bottom plate 1312 may both be 100 mm. The top plate 1311 and the bottom plate 1312 may both be steel plates. The main frame 110 may be welded using HN800X300X14X26L I-steel in the GB / T 11263 standard. Top plate 1311 and / or bottom plate 1312 are welded from relatively thicker steel plates, providing increased strength. It will be appreciated that when a compression device is installed, mounting portion 130 corresponds to the compression device and is subject to greater force. This arrangement provides increased strength for support plate assembly 1310. Furthermore, in embodiments incorporating a lifting member, reinforcing ribs may be provided on both sides of mounting portion 130 corresponding to the lifting member.

[0036] Exemplarily, the thickness of vertical plate 1313 can be 30 mm to 50 mm. For example, the thickness of vertical plate 1313 can be 30 mm, 40 mm, or 50 mm. Preferably, the thickness of vertical plate 1313 is 40 mm. This can better ensure the strength of support plate assembly 1310. Exemplarily, vertical plate 1313 can be a steel plate.

[0037] For example, with reference to Figure 2 and Figure 3 , the top of the top plate 1311 may be connected to a mounting plate 1320, and the mounting plate 1320 may be provided with an assembly part 1330 for mounting the compression device. Specifically, the mounting plate 1320 is against the top plate 1311. In the prior art, referring to Figure 1, a column 120' is provided on the main frame 110', and a mounting plate 1320' and an assembly part 1330' are provided on the top of the column 120'. In the mounting base 10 provided in this embodiment, the mounting plate 1320 is directly connected to the top of the top plate 1311. The space above the mounting base 10 occupied by the mounting plate 1320 and the assembly part 1330 is small, thereby avoiding interference between the compression device and other structural parts during rotation and ensuring a smooth rotation process. In addition, the positions of the mounting plate 1320 and the assembly part 1330 are relatively low, so when rotating, the compression device needs to be lifted to a lower height, that is, the rotation process is more convenient.

[0038] According to another aspect of the present invention, a booster unit is provided. The booster unit may include any of the aforementioned mounting bases 10. A rotating member for rotating the compression device is disposed on the rotating member mounting position 1201. The rotating member is used to rotate the compression device. Because the mounting base 10 employs the technical solutions of any of the aforementioned embodiments, the booster unit at least possesses the beneficial effects of the technical solutions of the aforementioned embodiments, which will not be further elaborated here.

[0039] For example, the booster unit may further include a compression device, which may be disposed within the mounting area and connected to each of the plurality of mounting portions 130. Furthermore, the compression device may be a cylindrical centrifugal compressor. For example, the compression device may be provided with a mounting adapter that may be mated and connected to the assembly 1330 of the mounting portion 130.

[0040] Exemplarily, the booster unit may further include a lifting member, the lifting member having a connecting end and a lifting end movable relative to the connecting end, the connecting end being connected to the compression device, and the lifting end being against the mounting portion 130. That is, the connecting end is on the compression device, and the lifting end is against the mounting portion 130, which makes it easier for the operator to operate the lifting member. Exemplarily, there may be multiple lifting members, and the lifting end of each lifting member is against the corresponding mounting portion 130. When the compression device needs to be inspected, the compression device is first lifted by the lifting member, and then the compression device is rotated by the rotating member, and then the rotated compression device is subjected to core pulling inspection and other operations. Exemplarily, the lifting member may be a jack, that is, the jack is inverted on the compression device.
