Description

Technical Field

[0001] The utility model relates to the technical field of barrel compressors, in particular to a horizontally rotating casing and a large barrel compressor. Background Art

[0002] Existing large cylindrical compressors do not have the function of horizontal rotation in situ. For example, due to the space limitation of the units on both sides, it is impossible to pull out the core for maintenance in situ, so the compressor needs to be lifted off the base. To solve this problem, the following two methods are usually used:

[0003] One is to use the overhead crane in the compressor plant to lift the compressor as a whole during maintenance and place it in the designated maintenance area. After the maintenance work is completed, the compressor is lifted back to the base using the overhead crane. This method first requires the use of a large-tonnage overhead crane in the plant, and secondly, it requires increasing the bearing capacity of the internal steel structure and foundation of the plant, which greatly increases the construction cost of the plant. In addition, since the large-tonnage overhead crane is only needed during the maintenance period, the frequency of use of the overhead crane is low, which directly leads to the extremely low cost-effectiveness of increasing the cost of building a compressor plant.

[0004] The second method is to use a large-tonnage truck crane to lift the compressor outside the compressor plant. This method requires the removal of the plant roof, and the removal and reinstallation of the plant roof takes up valuable maintenance time and incurs additional expenses. Secondly, when performing lifting operations, large-tonnage truck cranes have strict requirements on the lifting space and lifting environment, and the lifting accuracy is low. In addition, the shift fee of large-tonnage truck cranes is relatively expensive. The two liftings of the compressor during the maintenance period will incur high costs and take up a lot of compressor maintenance cycles. Utility Model Content

[0027] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0029] Refer to the following Figures 1 to 5 A horizontally rotating casing and a large cylindrical compressor are described according to some embodiments of the utility model, wherein the first direction refers to the axial direction of the casing, and the second direction refers to the direction perpendicular to the axial direction of the casing, and the first direction and the second direction are indicated in the figure.

[0030] like Figures 1 to 5 As shown, according to the embodiment of the first aspect of the utility model, a horizontally rotating casing for a large cylindrical compressor is provided, comprising a cylinder and a support device 2, the cylinder is a cylindrical structure processed by integral forging, and an air inlet 11 and an air outlet 12 are arranged on both sides of the cylinder along the first direction, a platform 13 is arranged at the bottom of the cylinder, and two symmetrically arranged keyways 131 are opened on the platform 13, the keyways 131 are used to install a rotating tool, and can provide a guiding and positioning function for the rotating tool, and at the same time, during the rotation of the casing, the keyways 131 can also assist in transmitting torque to prevent the casing and the rotating tool from generating relative displacement; the support device 2 is welded from a plate, and a plurality of support devices 2 are arranged under the cylinder, and the support device 2 is used to support the cylinder, and the support device 2 is also used to install a jacking tool. Therefore, the large compressor can be lifted and rotated in situ by using a jacking tool and a rotating tool, without the need to lift the whole machine off the base during disassembly and maintenance, thereby saving maintenance time and maintenance costs.

[0031] Specifically, when rotating the casing, first install the jacking tool to the supporting device 2, and by adjusting the jacking tool, the casing is raised and the supporting device 2 leaves the ground; then select a suitable keyway 131 to install the rotating tool, so that the keyway 131 cooperates with the rotating tool, thereby driving the casing to rotate, thereby realizing in-situ core pulling maintenance of large compressors.

[0032] Among them, a platform 13 is set at the bottom of the cylinder for opening a key groove 131, which can increase the contact area between the cylinder and the rotating tool and improve the bearing capacity of the rotating tool; the symmetrically arranged double key groove 131 structure can meet the two-way installation of the rotating tool, so that the staff can choose the key groove 131 on either side to install the rotating tool according to the actual layout of the compressor, thereby avoiding the inability to smoothly install the rotating tool due to limited space, greatly improving the convenience of operation.

[0033] The air inlet duct 11 and the air outlet duct 12 both adopt a plate press-welded structure, which can save materials and reduce processing costs.

[0034] It is understandable that the number of the supporting devices 2 is not limited here, and it only needs to achieve a stable supporting effect on the cylinder; the specific types and structures of the jacking tool and the rotating tool are not limited here, and it only needs to drive the housing to move in the vertical direction through the jacking tool and drive the housing to rotate through the rotating tool. Preferably, four supporting devices 2 are provided on the cylinder, respectively located at the four corners of the bottom platform 13 of the cylinder.

[0035] like Figure 1 , Figure 4 and Figure 5 As shown, the supporting device 2 includes a bottom plate 21, a rib plate 22 and a supporting block 23. The bottom plate 21 is provided with a U-shaped groove 211 for providing space for the installation and use of a jacking tool. The rib plate 22 includes connecting parts 221 arranged opposite to each other in a vertical direction. The connecting parts 221 are located on both sides of the U-shaped groove 211. The bottom of the rib plate 22 is connected to the bottom plate 21, and the top of the rib plate 22 is connected to the cylinder. The supporting block 23 is connected to the connecting part 221. The supporting block 23 is arranged opposite to the U-shaped groove 211, so that the jacking tool can be supported on the ground at one end through the U-shaped groove 211, and the other end is against the supporting block 23, thereby realizing the jacking effect on the casing. The setting height of the supporting block 23 is calculated according to the outer dimensions of the jacking tool and the maximum jacking height. The supporting block 23 is provided with a mounting hole 231 for mounting the jacking tool.

[0036] It is understandable that the compressor is usually installed on a base inside a factory building. Connection holes are opened on the bottom plate 21 so that the connection holes are located on both sides of the U-shaped groove 211. The support device 2 is connected to the base through the connection holes to fix the compressor; at the same time, the detachable connection between the bottom plate 21 and the base can provide adjustment space for the cold centering of the compressor. Preferably, the connection hole is a threaded hole.

[0037] Preferably, a jack is used as a lifting tool to save costs. The fixing frame at the bottom of the jack is connected to the mounting hole 231, so that the protruding end of the jack passes through the U-shaped groove 211 and is supported on the base inside the factory building, so that the jack is installed on the supporting device 2. At this time, the mounting hole 231 is preferably a threaded hole, and two threaded holes are provided on the outer surface of the supporting block 23.

[0038] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the horizontally rotating housing further includes legs 14, which are symmetrically arranged on both sides of the cylinder along the second direction, and are used to provide fulcrums when the housing is hoisted, turned over, and transported. Specifically, the legs 14 are provided with arc-shaped concave structures, so that the housing can be hung on the hook; a circular baffle is also provided on the end of the legs 14 away from the cylinder, which is used to prevent the hook from coming off and causing the housing to fall. When the housing is transported, the legs 14 can also be used to fix the housing to avoid collision.

[0039] like Figure 3 , Figure 4 and Figure 5 As shown, the horizontally rotating housing also includes a first positioning key 111 and a second positioning key 121. The first positioning key 111 is arranged at the bottom of the air inlet tube 11 along the first direction, and the second positioning key 121 is arranged at the bottom of the air outlet tube 12 along the first direction, for positioning the housing along the second direction.

[0040] like Figure 1 As shown, the horizontally rotating housing further comprises a positioning groove 212, which is opened at the bottom of the bottom plate 21 along the second direction and is used to position the housing along the first direction. Preferably, the positioning groove 212 is arranged on the driving side of the compressor.

[0041] Specifically, the positioning groove 212 arranged on the base plate 21 works together with the first positioning key 111 arranged on the air inlet pipe 11 and the second positioning key 121 arranged on the air outlet pipe 12 to prevent the large compressor from shifting, maintain the centering accuracy of the large compressor, and adapt to the thermal expansion and deformation of the casing of the large compressor caused by temperature changes during operation.

[0042] like Figure 3 , Figure 4 and Figure 5 As shown, the horizontally rotating casing also includes a first reinforcing rib 112 and a second reinforcing rib 122 . The first reinforcing rib 112 is connected to the cylinder and the air inlet duct 11 ; the second reinforcing rib 122 is connected to the cylinder and the air outlet duct 12 , and is used to reinforce the air inlet duct 11 and the air outlet duct 12 .

[0043] It is understandable that the number and size of the first reinforcing ribs 112 and the second reinforcing ribs 122 are not limited here, and it is only necessary to achieve the reinforcement effect on the air inlet duct 11 and the air outlet duct 12. The specific size of the first reinforcing ribs 112 and the second reinforcing ribs 122 is determined by the installation and use space required by the rotating tool and the strength of the cylinder itself. Preferably, four first reinforcing ribs 112 are welded to the cylinder and the air inlet duct 11, and four second reinforcing ribs 122 are welded to the cylinder and the air outlet duct 12.

[0044] like Figure 1 and Figure 3 As shown, the horizontally rotating housing further includes an annular reinforcing rib 15, and a plurality of annular reinforcing ribs 15 are sequentially arranged on the outside of the cylinder along the first direction, and the annular reinforcing ribs 15 are located in the upper half of the cylinder. Preferably, the annular reinforcing ribs 15 are arranged on both sides of the legs 14 and the supporting device 2 along the first direction, and when the housing is lifted up using a lifting tool, the annular reinforcing ribs 15 can transmit the supporting force; at the same time, the annular reinforcing ribs 15 can also play a role in assisting the positioning of the legs 14 and the supporting seat.

[0045] According to the second aspect of the present invention, a large cylindrical compressor is provided, comprising a horizontally rotating casing as provided in the first aspect. Thus, the large compressor can be lifted and rotated in situ by using a lifting tool and a rotating tool, without the need to lift the entire machine off the base during disassembly and maintenance, thereby saving maintenance time and maintenance costs.
