Description

Technical Field

[0001] This application relates to the field of base technology, specifically to a base and compressor device. Background Technology

[0002] Screw compressors, as highly efficient gas compression equipment, are widely used in various fields of industrial production. Their stability and service life largely depend on the installation accuracy and dynamic balance of the screw compressor unit. However, in actual construction sites, the installation of screw compressor units often faces many challenges, among which leveling difficulties are a common problem.

[0003] Traditional installation methods typically rely on the installer's experience, using simple tools like triangular iron blocks for forced leveling. While this method can achieve initial stability of the screw compressor unit in the short term, its crude and imprecise leveling technique easily leads to uneven stress on the frame. Over time, this uneven stress can cause bending deformation of the screw compressor unit's steel structure, thus affecting the unit's dynamic balance.

[0004] Dynamic imbalance in screw compressor units not only increases compressor vibration but also causes additional wear on core components, significantly reducing the compressor's lifespan. Furthermore, increased vibration can lead to increased noise, affecting the comfort and safety of the working environment. Therefore, achieving precise leveling of screw compressor units during installation to ensure their long-term stable operation has become a pressing technical problem. Utility Model Content

[0005] The purpose of this application is to provide a base and compressor equipment that can solve the technical problems of uneven stress on the frame caused by the use of simple tools such as triangular iron blocks for forced leveling by installers. This affects the dynamic balance of the screw compressor unit, reduces the service life of the screw compressor, and affects the comfort and safety of the working environment.

[0038] This application provides a compressor device, including a base and a compressor (not shown), wherein the compressor is mounted on a compressor foot on the base.

[0039] Please see Figures 1-3 The base includes a frame 101. The frame 101 includes a receiving cavity 11 and side plates 12 joined end-to-end to form the receiving cavity 11. The receiving cavity 11 includes at least one grouting cavity 1101, a first drainage cavity 1102, and a second drainage cavity 1103. The side plate 12 includes a main plate 121, a top plate 122, and a bottom plate 123. The top plate 122 protrudes from the top of the main plate 121, and the bottom plate 123 protrudes from the bottom of the main plate 121. Both the top plate 122 and the bottom plate 123 are located on the side of the main plate 121 away from the receiving cavity 11. The bottom plate 123 is provided with a first screw hole 1231 and a first fastening hole 1232. In this embodiment, the frame 101 includes four side plates 12 joined end-to-end, each side plate 12 being an integrally formed U-shaped channel steel.

[0040] Please see Figures 1-4 The base also includes a set screw pad 102 and a leveling set screw 103. The set screw pad 102 is located on the side of the base plate 123 facing the top plate 122. The set screw pad 102 has a second screw hole 21 at the position corresponding to the first screw hole 1231. The leveling set screw 103 passes through the second screw hole 21 and the first screw hole 1231 in sequence and is used to abut against the set screw pad on the foundation. By having the leveling set screw 103 pass through the first screw hole 1231 and abut against the set screw pad on the foundation, efficient and precise leveling can be performed during the installation of the base, simplifying the on-site installation steps of the base, reducing installation time and labor costs, and improving the installation efficiency of the base. Leveling the base by using the leveling set screw 103 can avoid uneven force on the base caused by using triangular iron blocks for violent leveling, so that the dynamic balance of the compressor equipment is maintained, reducing the vibration and wear of the compressor, thereby increasing the service life of the compressor. By increasing the stress-bearing area through the top screw pad 102, the stress on the base plate 123 is dispersed, reducing local stress concentration on the base plate 123, lowering the risk of deformation of the base plate 123, ensuring the stability of the base in long-term use, and increasing the service life of the base.

[0041] Please see Figure 3 The frame 101 also includes a partition 13, which is disposed within the accommodating cavity 11 and connected to the side plate 12. In this embodiment, the partition 13 is welded to the side plate 12, and the partition 13 is an integrally formed U-shaped channel steel. In other words, the partition 13 also includes a main plate 121, a top plate 122, and a bottom plate 123.

[0042] Please see Figure 1 and Figure 5 The base also includes an anti-slip cover plate 104. The anti-slip cover plate 104 is disposed on the top surface of the partition plate 13. The anti-slip cover plate 104 prevents construction personnel from falling. The anti-slip cover plate 104 is provided with at least one grouting through hole 41 at the position corresponding to any grouting cavity 1101. In this embodiment, the anti-slip cover plate 104 is provided with a grouting through hole 41 at the position corresponding to any grouting cavity 1101.

[0043] Please see Figure 1 , Figure 3 and Figure 5 The base also includes at least one grouting port 105. Each grouting port 105 is connected to a grouting through hole 41, and the top of the grouting port 105 is higher than the top surface of the anti-slip cover plate 104. In this embodiment, the orthographic projection of the grouting port 105 on the horizontal plane coincides with the orthographic projection of the grouting through hole 41 on the horizontal plane. It is worth noting that the position of the grouting port 105 should not obstruct the installation of equipment on the base, nor interfere with pipelines within the base. By setting the grouting port 105 and ensuring its top is higher than the top surface of the anti-slip cover plate 104, it is easier for construction personnel to observe the cement grouting height during grouting, control the amount of grout, ensure the cement is level and does not overflow, and prevent secondary grouting splashing. This also prevents on-site construction personnel from directly pouring cement into the grouting through hole 41, which could cause cement splashing, polluting and messing the environment around the compressor unit, and causing uneven cement layers that would affect after-sales maintenance.

[0044] Please see Figure 1 , Figure 3 and Figure 5The anti-slip cover 104 has a first drainage hole 42 at a position corresponding to the first drainage chamber 1102, and the first drainage hole 42 communicates with the first drainage chamber 1102. The base also includes a first drainage net 106, a drainage port 107, and a first drainage pipe 108. The first drainage net 106 is installed in the first drainage hole 42 and communicates with the first drainage hole 42. The drainage port 107 is located outside the receiving cavity 11, one end of the first drainage pipe 108 is connected to the first drainage chamber 1102, and the other end of the first drainage pipe 108 is connected to the drainage port 107. By using the first sewage discharge net 106, the first sewage discharge through hole 42, the first sewage discharge chamber 1102, the first sewage discharge pipe 108 and the sewage discharge port 107 together, the sewage on the anti-slip cover 104 can be effectively discharged, meeting the cleanliness requirements of the base, preventing sewage from accumulating on the anti-slip cover 104 and causing increased surface corrosion of the anti-slip cover 104, and effectively improving the reliability of the base.

[0045] Please see Figure 1 , Figure 3 and Figure 5 The anti-slip cover 104 has a second drainage through hole 43 at a position corresponding to the second drainage chamber 1103. The second drainage through hole 43 communicates with the second drainage chamber 1103. The first drainage chamber 1102 and the second drainage chamber 1103 are respectively located at two opposite corners of the receiving cavity 11. The base also includes a second drainage net 109 and a second drainage pipe 110. The second drainage net 109 is installed in the second drainage through hole 43 and communicates with the second drainage through hole 43. One end of the second drainage pipe 110 is connected to the second drainage chamber 1103, and the other end of the second drainage pipe 110 is connected to the first drainage chamber 1102. In addition to the first sewage discharge net 106, the first sewage discharge through hole 42, the first sewage discharge chamber 1102, the first sewage discharge pipe 108, and the sewage discharge outlet 107, a second sewage discharge net 109, a second sewage discharge through hole 43, a second sewage discharge chamber 1103, and a second sewage discharge pipe 110 are added. This can accelerate the discharge of sewage from the anti-slip cover plate 104, prevent sewage from accumulating on the anti-slip cover plate 104 and causing increased surface corrosion, and further effectively improve the reliability of the base.

[0046] Please see Figure 1 and Figure 6 The base also includes a dike 111. The dike 111 is located on the top surface of the frame 101. The dike 111 prevents sewage from overflowing from the anti-slip cover 104, keeping the area around the base clean.

[0047] Please see Figure 1 and Figure 6The base also includes leveling blocks 112. Leveling blocks 112 are located at the corners of the frame 101. The cofferdam 111 is recessed at the position corresponding to the leveling blocks 112 to place the leveling blocks 112 outside the cofferdam 111. In this embodiment, the base includes four leveling blocks 112, respectively located at the four corners of the frame 101. By placing four leveling blocks 112 at the four corners of the top of the frame 101, these leveling blocks 112 are machined steel blocks, making it convenient for on-site operators to place a level on the leveling blocks 112 for leveling operations, greatly facilitating the operation of on-site construction personnel and saving time and effort. It is worth noting that in other embodiments, only three leveling blocks 112 can be used for leveling operations.

[0048] Please see Figure 1 , Figure 2 and Figure 7 The base includes fasteners 114 on the foundation. The base also includes fastening pads 113. Fastening pads 113 are disposed on the top and / or bottom surfaces of the base plate 123. In this embodiment, fastening pads 113 are disposed on both the top and bottom surfaces of the base plate 123. Fastening pads 113 have a second fastening hole 131 at a position corresponding to the first fastening hole 1232. Both the first and second fastening holes 1232 allow the fasteners 114 to pass through to secure the base and foundation. In this embodiment, the lower part of the fastener 114 is embedded in the foundation, and the upper part of the fastener 114 protrudes outside the foundation. When the base arrives at the construction site after leaving the factory, the first fastening hole 1232 is aligned with the fastener 114 on the foundation, allowing the fastener 114 to pass through the first and second fastening holes 1232 and 131 to secure the base and foundation. By increasing the force-bearing area through the fastening pad 113, the force on the first fastening hole 1232 is dispersed, reducing local stress concentration on the base plate 123, lowering the risk of deformation of the base plate 123, ensuring the stability of the base in long-term use, and increasing the service life of the base.

[0049] Please see Figure 1 The base also includes a support rib 115. The support rib 115 is connected to both ends of the fastening pad 113 located on the top surface of the base plate 123, and the support rib 115 connects the top plate 122 and the base plate 123. The support rib 115 supports the top plate 122 and the base plate 123, thereby improving the stability of the side plate 12.

[0050] Please see Figure 1 The base also includes a grounding plate 116. The grounding plate 116 is disposed on the side plate 12. In this embodiment, the base includes two grounding plates 116, which are respectively disposed on the main plates 121 of two opposite side plates 12. By stringing iron chains through the grounding plates 116, static electricity inside the base can be effectively conducted.

[0051] Please see Figure 1 The base also includes lifting lugs 117. The lifting lugs 117 are disposed on the side plates 12. In this embodiment, the base includes four lifting lugs 117, which are symmetrically disposed on the main plates 121 of two opposite side plates 12. When the base arrives at the construction site after leaving the factory, it is lifted and placed onto the corresponding foundation using the lifting lugs 117.

[0052] Please see Figure 1 The base also includes a compressor foot 118, a gearbox foot 119, and a motor foot 120. The compressor foot 118 is mounted on the anti-slip cover 104 and is used to mount the compressor. The gearbox foot 119 is mounted on the anti-slip cover 104 and is used to mount the gearbox. The motor foot 120 is mounted on the anti-slip cover 104 and is used to mount the motor.

[0053] Please see Figure 8 and Figure 9 In this application, the base is equipped with a leveling screw 103. When leveling is performed by the leveling screw 103, the stress on the base is more uniform and the deformation of the base is smaller.
