[0042] In the embodiment of the present invention, the compressor body 1 in the present application is a screw compressor, whose working principle mainly relies on two intermeshing screws (usually a single screw or a twin screw design) to achieve gas compression, and its working process includes;

[0043] Suction stage: The gas enters the working chamber of the compressor through the air inlet. During this stage, the space on both sides of the screw is relatively large and the gas pressure is low, allowing the gas to enter smoothly.

[0044] Compression stage: As the screw rotates, the gas is trapped in the screw thread groove. The rotation of the screw causes the gas to move forward along the screw axis, while the volume of the compression chamber gradually decreases, causing the gas pressure to gradually increase. At this stage, the temperature of the gas will also increase.

[0045] Exhaust stage: When the gas is compressed to a predetermined pressure, the compressed gas is discharged through the exhaust port. Due to the continuous rotation of the screw, new gas enters the working chamber, forming a continuous compression process.

[0046] The screw compressor has the advantages of high efficiency, continuous operation, low noise and simple maintenance. The second limiting part 62 also includes a limiting plate 6211 and a second spring 6212. The two limiting plates 6211 are fixedly connected to the surface of the I-beam 621. The two limiting plates 6211 are in contact with the surface of the pre-installed disk 2 and the base 3 respectively. The second spring 6212 is connected between the limiting plate 6211 and the second transmission gear 6221. When the compressor body 1 is working, the second spring 6212 can ensure that the screw compressor plays an elastic buffering role during installation and operation. The limiting block 411 is a wedge-shaped block with an inclined surface. When the base 3 is installed, the base 3 can be fixed to the specified position of the cold storage room by using the ground bolts, or the pre-installed disk 2 and the base 3 can be fixed by using the I-beam 621, and then the pre-installed compressor can be moved to the specified position of the cold storage room by using a mobile vehicle or lifting equipment.

[0047] See also Figure 6 In one embodiment of the present invention, the first limiting portion 41 further includes an arc-shaped shell 413 and an elastic rubber ring 414 , the other end of the movable pin 412 is fixedly connected to the arc-shaped shell 413 , and the elastic rubber ring 414 penetrates a plurality of arc-shaped shells 413 .

[0048] In the embodiment of the present invention, the design of the elastic rubber ring 414 that is annularly penetrates the arc-shaped shell 413, when there is no positioning column 21, the pre-installed disk 2 cannot be assembled along the axis of the base 11 or tilted with the base 11. Even if one of the limit blocks 411 in the pre-installed component 4 is first squeezed or aligned with the first plug-in hole 13, the elastic force of the elastic rubber ring 414 drives several limit blocks 411 to shrink synchronously or enter different first plug-in holes 13 synchronously.

The first transmission gear 531 is fixedly connected to the transmission rod 532. The transmission rod 532 is movably sleeved in the first rotating tube 521. A limiting groove is provided on the inner wall of the first rotating tube 521. A limiting rib 533 is provided on the surface of the transmission rod 532. The limiting rib 533 is slidably connected to the limiting groove. The first gear ring 42 and the second gear ring 61 are both transmission-connected to the first transmission gear 531.

[0050] See also Fig.11 Furthermore, the distance between the first gear ring 42 and the surface of the pre-loaded disk 2 is greater than the distance between the second gear ring 61 and the surface of the pre-loaded disk 2 , and the first transmission gear 531 is distributed between the first gear ring 42 and the second gear ring 61 .

[0051] See also Figures 7 to 13 Furthermore, the control assembly 5 also includes an adjustment part 54, which includes a meniscus 541, an adjustment rod 542 and a third knob 543. The meniscus 541 and the third knob 543 are both fixedly connected to the adjustment rod 542, the meniscus 541 is in sliding contact with the surface of the first transmission gear 531, and the adjustment rod 542 is connected to the pre-loaded disk 2.

[0052] See also Figures 11 to 13 Furthermore, the meniscus 541 includes an arcuate edge and a straight edge, and the driven part 52 also includes a first spring 523 , and the first spring 523 is connected between the worm gear 522 and the first transmission gear 531 .

[0053] In an embodiment of the present invention, when the center position of the arc-shaped edge contacts the surface of the first transmission gear 531, the first transmission gear 531 is connected to the first gear ring 42 for controlling the limit block 411 to be plugged into the second plug-in hole 14; when the straight edge contacts the first transmission gear 531, the first transmission gear 531 is connected to the second gear ring 61 for controlling the I-beam 621 to rotate 90 degrees.

[0054] Working principle: Factory pre-installation steps: First, use the first knob 512 to rotate the worm 511. The rotating worm 511 drives the first rotating tube 521, the limiting rib 533, the transmission rod 532 and the first transmission gear 531 to rotate through the worm gear 522. The rotating first transmission gear 531 drives the second rotating tube 622 and the I-bar 621 to rotate through the second gear ring 61 and the second transmission gear 6221, which is used to drive the end of the I-bar 621 to be parallel to the second plug hole 14. Then, the positioning column 21 on one side of the pre-installed disk 2 is inserted into the first positioning hole 12 on the surface of the base 11. Then, the pre-installed disk 2 is rotated while pressing. The limiting block 411 and the I-bar 621 are subjected to pressure from the surface of the base 11. The pressure on the limiting block 411 is overcome. The elastic force of the elastic rubber ring 414 drives the limit block 411, the movable pin 412 and the arc shell 413 to perform a contraction movement along the linear guide rail 23. The pressure on the I-shaped rod 621 overcomes the elastic force of the second spring 6212 to drive the I-shaped rod 621 to move along the axis of the second rotating tube 622. The movable pin 412 moving along the linear guide rail 23 drives the first gear ring 42 to rotate through the arc guide rail 421. The rotating first gear ring 42 drives the remaining movable pins 412 and the limit block 411 to move synchronously through the arc guide rail 421 and the movable pin 412. When the limit block 411 enters the first plug hole 13, the elastic force of the second spring 6212 drives the I-shaped rod 621 to enter the second plug hole 14, which has the characteristic of being easy to assemble.

[0055] Cold storage room installation steps: Method 1, first use the ground bolts to fix the base 3 at the specified position of the cold storage room, then use the mobile body or lifting equipment to move the pre-installed compressor to the position of the base 3, and then insert the positioning column 21 on the other side of the pre-installed disk 2 into the second positioning hole 31 on the surface of the base 3, and then rotate the base 11 with the positioning column 21 as the axis. When the other end of the I-beam 621 is aligned with the third plug hole 33, the elastic force of the second spring 6212 drives the I-beam 621 into the third plug hole 33, and then use the worm 511 and the worm wheel 522 to drive the I-rod 621 to rotate 90 degrees, so that the I-rod 621 is perpendicular to the second plug hole 14 and the third plug hole 33 at the same time, and then use the I-rod 621 to fix the pre-installed disk 2 and the base 3; Method 2, first use the I-rod 621 to fix the pre-installed disk 2 and the base 3, and then use a mobile body or lifting equipment to move the pre-installed compressor to the designated position of the cold storage room, and finally use the ground bolts to fix the base 3 to the ground of the cold storage room.

[0056] When the compressor body 1 needs to be disassembled separately for maintenance, first use the worm 511 and the worm wheel 522 to drive the I-rod 621 to rotate 90 degrees, so that the I-rod 621 is parallel to the second plug hole 14 and the third plug hole 33 at the same time, and then use the third knob 543 to rotate the adjusting rod 542 and the meniscus 541, so that the center position of the arc edge of the meniscus 541 contacts the surface of the first transmission gear 531. At this time, the first transmission gear 531 is connected to the first gear ring 42. Then, the worm 511 and the worm wheel 522 are used to drive the first gear ring 42 to rotate. The rotating first gear ring 42 drives the remaining movable pins 412 and the limit block 411 to move synchronously by sliding connection with the arc guide rail 421 and the movable pin 412, thereby driving the limit block 411 to disengage from the first plug hole 13. Finally, the compressor body 1 is moved to the maintenance position using lifting equipment.

[0057] In summary, the present application utilizes a structural design in which the base 11, the pre-installed disk 2, the pre-installed component 4, the final assembly component 6 and the control component 5 cooperate with each other. On the one hand, the base 11 and the pre-installed disk 2 can be fixed by the limit block 411 at the factory stage. On the other hand, the base 11, the pre-installed disk 2 and the base 3 can be fixed by the I-beam 621. When disassembly and maintenance are required, the compressor body 1 can be disassembled by only controlling the movement of several limit blocks 411 and rotating several I-beams 621 90 degrees using the control component 5. Compared with the traditional fixing method, there is no need to use disassembly tools such as wrenches, and the compressor body 1 can be quickly fixed and disassembled, which has the characteristics of easy installation and disassembly.
