Description

Technical Field

[0001] This application relates to the field of diaphragm compressors, and more particularly to an automatic turning device for diaphragm compressors. Background Technology

[0002] A diaphragm compressor is a reciprocating compressor that compresses and transports gas by the reciprocating motion of a diaphragm within a cylinder. The main application areas for diaphragm compressors include: nuclear power, food and pharmaceuticals, petrochemicals, electronics, materials, defense, and scientific research.

[0003] When a diaphragm compressor is started in the workshop, it undergoes a manual rotation. This rotation prevents the transmission mechanism from jamming due to the transport of highly viscous media. It also checks the internal components of the diaphragm compressor for smooth operation, checking for any jamming or abnormal noises, preventing pump damage or motor burnout due to excessive current during startup. Furthermore, it serves to warm up the compressor and lubricate it before start-up, preventing localized overheating of the rotor and casing after startup, which could lead to thermal deformation.

[0004] Regarding the aforementioned technologies, the inventors believe that during the rotation of the compressor, a drive rod is typically used to rotate the large flywheel of the diaphragm compressor. This rotation drives the internal units to operate, thus achieving the rotation of the diaphragm compressor. The compressor is then started once it is running at a uniform speed without jamming. However, in actual operation, it generally requires personnel to manually rotate the compressor on-site. The workshop environment is harsh, with areas containing high levels of radiation, which is harmful to human health. Summary of the Invention

[0005] To facilitate automatic rotation of diaphragm compressors without requiring on-site personnel, this application provides an automatic rotation device for diaphragm compressors.

[0006] The automatic turning device for a diaphragm compressor provided in this application adopts the following technical solution:

[0007] An automatic turning device for a diaphragm compressor includes a frame, a turning gear mounted on the frame, a drive assembly for driving the turning gear to rotate a large flywheel on the diaphragm compressor, a reciprocating assembly for controlling the meshing and disengagement of the turning gear and the large flywheel, and a gear alignment assembly for adjusting the angle of the turning gear.

[0008] The diaphragm compressor is equipped with a first angle encoder for determining the angle of the large flywheel, and a second angle encoder is equipped on the frame for determining the angle of the turning gear.

[0009] The drive assembly includes a drive motor and a drive shaft. The turning gear is mounted on the drive shaft, and the drive motor drives the drive shaft to rotate. The drive shaft drives the turning gear to rotate, and the turning gear is displaced along the length of the drive shaft. The turning gear engages with or disengages from the large flywheel through the displacement on the drive shaft.

[0010] The reciprocating assembly drives the turning gear to move on the drive shaft; the gear alignment assembly drives the drive shaft to rotate, thereby driving the turning gear to rotate.

[0011] By adopting the above technical solution, during the rotation process, the first and second angle encoders measure the meshing angle between the large flywheel and the rotation gear, respectively. The gear calibration component adjusts the arrangement angle of the rotation gear, and the reciprocating component drives the rotation gear to mesh with the large flywheel. The drive component drives the rotation gear to rotate, which in turn drives the large flywheel to rotate, thus rotating the diaphragm compressor. After rotation, the reciprocating component drives the rotation gear to disengage from the large flywheel, and then the diaphragm compressor is started normally. By setting up an automatic rotation device, the diaphragm compressor is automatically rotated. During the rotation process, the operator only needs to control and adjust the normal operation of each component to accurately drive the large flywheel through the rotation gear, thereby rotating the diaphragm compressor.

[0012] Optionally, the reciprocating assembly includes a reciprocating motor mounted on a frame, a reciprocating shaft, and a reciprocating sleeve sleeved on the reciprocating shaft;

[0013] The reciprocating shaft is arranged coaxially with the drive shaft;

[0014] The reciprocating sleeve is threadedly connected to the reciprocating shaft, and the reciprocating sleeve moves along the length of the reciprocating shaft. One end of the reciprocating sleeve is rotatably connected to the turning gear.

[0015] The reciprocating sleeve is connected to the reciprocating shaft, and the reciprocating sleeve moves along the length of the reciprocating shaft. One end of the reciprocating sleeve is rotatably connected to the turning gear. The connection between the reciprocating sleeve and the reciprocating shaft is a threaded connection or a ball screw connection.

[0016] By adopting the above technical solution, the reciprocating motor rotates, driving the reciprocating shaft to rotate. When the reciprocating shaft rotates, it drives the reciprocating sleeve to move along the length of the reciprocating shaft. When the reciprocating shaft moves, it drives the slewing gear to move along the drive shaft, thereby driving the slewing gear to mesh and disengage with the large flywheel. This facilitates the adjustment of the position of the slewing gear. By using the reciprocating motor to drive the position movement of the slewing gear, the range of the slewing gear's position movement can be made more precise.

[0017] Optionally, a connecting ring is fixedly connected to the outer side of one end of the reciprocating sleeve, and an end cap is fitted onto the reciprocating sleeve, wherein the inner ring diameter of the end cap is smaller than the outer ring diameter of the connecting ring.

[0018] The reciprocating sleeve has a connecting ring at one end, which is inserted into the tooth surface of the turning gear, and the end cover is fixedly connected to the turning gear.

[0019] By adopting the above technical solution, the end cap and the connecting ring together restrict the separation between the reciprocating sleeve and the turning gear, making the rotational connection between the reciprocating sleeve and the turning gear more stable.

[0020] Optionally, a bearing is installed between the connecting ring and the turning gear.

[0021] By adopting the above technical solution, the rotational connection between the turning gear and the connecting ring becomes smoother.

[0022] Optionally, a second support plate is fixedly connected to the frame, and a guide groove is provided on the reciprocating sleeve, which runs through the length of the reciprocating sleeve. The upper side of the second support plate is inserted into the guide groove.

[0023] By adopting the above technical solution, the upper side of the two support plates is inserted into the guide groove. The cooperation between the second support plate and the guide groove on the reciprocating sleeve restricts the rotation of the reciprocating sleeve, so that when the reciprocating shaft rotates, it drives the reciprocating sleeve to move, thereby facilitating the meshing and separation between the reciprocating sleeve and the turning gear and the large flywheel.

[0024] Optionally, a first support plate is fixedly connected to the frame. The first support plate is arranged on the lower side of the reciprocating motor and is fixedly connected to the reciprocating motor, supporting the reciprocating motor.

[0025] By adopting the above technical solution, the first support plate supports the reciprocating motor, which increases the gap between the reciprocating shaft and the frame, facilitating the coaxial arrangement between the reciprocating shaft and the drive shaft, thereby facilitating the displacement of the reciprocating sleeve driving the turning gear on the drive shaft.

[0026] Optionally, the second support plate is arranged on the lower side of the reciprocating shaft, and two control switches are installed on the surfaces of the second support plate and the first support plate opposite each other. A positioning plate is fixedly connected to the reciprocating sleeve. The positioning plate is arranged between the first support plate and the second support plate. As the reciprocating sleeve moves, the positioning plate contacts the two control switches respectively and controls the reciprocating motor to shut down.

[0027] By adopting the above technical solution, as the positioning plate contacts the two control switches, the displacement distance of the reciprocating sleeve is controlled, and the control switches control the reciprocating motor to shut down, which can effectively adjust the displacement distance of the turning gear, making the displacement value of the turning gear more accurate.

[0028] Optionally, a reducer is installed between the drive motor and the drive shaft, and the drive motor transmits power to the drive shaft through the reducer.

[0029] By adopting the above technical solution, when the drive motor transmits power to the drive shaft through the reducer, the torque on the drive shaft is greater, making it easier for the disc gear to drive the large flywheel to rotate.

[0030] Optionally, the tooth alignment assembly includes a calibration motor, which drives a drive shaft to rotate via a reducer.

[0031] By adopting the above technical solution, the calibrator motor drives the turning gear to rotate on a small scale when it starts, thereby adjusting the angle of the turning gear under normal operation so that the arrangement angle of the turning gear matches the arrangement angle of the large flywheel.

[0032] Optionally, the drive motor and the calibration motor are mounted on a reducer, and the reducer is equipped with a clutch for adjusting the rotational gear.

[0033] A reducer is installed between the drive motor and the drive shaft, and the drive motor transmits power to the drive shaft through the reducer.

[0034] By adopting the above technical solution, the rotation of the turning gear can be facilitated, and the space occupied can be reduced.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. By setting up an automatic turning device, the diaphragm compressor is automatically turned. During the turning process, the operator only needs to control and adjust the normal operation of each component to accurately drive the large flywheel through the turning gear, thereby automatically turning the diaphragm compressor.

[0037] 2. By setting up a reciprocating component, it is convenient to control the displacement of the turning gear;

[0038] 3. By setting up a gear alignment component, the angle of the turning gear can be easily adjusted, making it easy for the turning gear to align and mesh with the large flywheel. Attached Figure Description

Detailed Implementation

[0046] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0047] This application discloses an automatic turning device for a diaphragm compressor. (Refer to...) Figure 1 The automatic turning device for the diaphragm compressor includes a frame 1, a turning gear 2 mounted on the frame 1, a drive assembly 3 for driving the turning gear 2 to rotate the large flywheel 4 on the diaphragm compressor, a reciprocating assembly 5 for controlling the meshing and disengagement of the turning gear 2 and the large flywheel 4, and a gear alignment assembly 6 for adjusting the meshing angle between the turning gear 2 and the drive gear. A first angle encoder 7 is installed on the diaphragm compressor to determine the angle of the large flywheel 4, and a second angle encoder 8 is installed on the frame 1 to determine the angle of the turning gear 2. During the turning process, the first angle encoder 7 and the second angle encoder 8 respectively measure the meshing angle between the large flywheel 4 and the turning gear 2. The gear alignment assembly 6 adjusts the arrangement angle of the turning gear 2, the reciprocating assembly 5 drives the turning gear 2 to mesh with the large flywheel 4, the drive assembly 3 drives the turning gear 2 to rotate, and the turning gear 2 drives the large flywheel 4 to rotate, thus turning the diaphragm compressor. After the turning is completed, the reciprocating assembly 5 drives the turning gear 2 to disengage from the large flywheel 4, and then the diaphragm compressor is started normally. By setting up an automatic turning device, the diaphragm compressor is automatically turned. During the turning process, the operator only needs to control and adjust the normal operation of each component to accurately drive the large flywheel 4 through the turning gear 2, thereby automatically turning the diaphragm compressor.

[0048] Reference Figure 2 , Figure 3 The first angle encoder 7 and the second angle encoder 8 are detectors that can output angle data within one revolution of the motor to an external target. The first angle encoder 7 is mounted on the same shaft as the large flywheel 4, and the second angle encoder 8 is mounted on the same shaft as the turning gear 2.

[0049] Reference Figure 2 , Figure 3 The drive assembly 3 includes a drive motor 31 fixedly connected to a bracket and a drive shaft 32 driven by the drive motor 31. A rotating gear 2 is sleeved on the drive shaft 32, and the rotating gear 2 and the drive shaft 32 are connected by a key, so that the rotation of the drive shaft 32 can drive the rotating gear 2 to rotate. Furthermore, when the rotating gear 2 is installed on the drive shaft 32, it can move along the length of the drive shaft 32. The large flywheel 4 of the diaphragm compressor is installed on the upper side of the drive shaft 32, and the rotating gear 2 engages or disengages with the large flywheel 4 by moving along the drive shaft 32. A reducer is provided between the drive motor 31 and the drive shaft 32 to increase the torque when the drive shaft 32 drives the rotating gear 2 to rotate, facilitating the rotation of the large flywheel 4. In this embodiment, a first reducer 33 and a second reducer 34 are installed between the drive motor 31 and the drive shaft 32. The first reducer 33 and the second reducer 34 are connected by a torque limiter, and the second reducer 34 is fixedly connected to the frame 1. The first reducer 33 is arranged above the second reducer 34, and the drive motor 31 is connected to the first reducer 33. The power of the drive motor 31 is transmitted to the drive shaft 32 through the first reducer 33 and the second reducer 34, driving the turning gear 2 to rotate. The second reducer 34 extends through both ends of the drive shaft 32, and a second angle encoder 8 is installed on one end of the drive shaft 32. The second angle encoder 8 and the turning gear 2 are respectively installed on both sides of the second reducer 34.

[0050] When the large flywheel contacts the turning gear, if there is a foreign object between the large flywheel and the turning gear, the torque of the second reducer 34 will be greater than the set value. Under the action of the torque limiter, the first reducer 33 and the second reducer 34 will separate, mainly to ensure that the overall transmission mechanism will not be damaged and will not cause damage to the diaphragm compressor.

[0051] Reference Figure 3 , Figure 4The reciprocating assembly 5 includes a reciprocating motor 51 mounted on the frame 1. A reciprocating shaft 52 is mounted on the output shaft of the reciprocating motor 51. The reciprocating shaft 52 is a threaded shaft and is coaxially arranged with the drive shaft 32. The reciprocating motor 51 drives the reciprocating shaft 52 to rotate. A reciprocating sleeve 53, which is threadedly engaged with the reciprocating shaft 52, is sleeved on the reciprocating shaft 52. The reciprocating sleeve 53 is rotatably connected to the turning gear 2. When the turning gear 2 rotates, the reciprocating sleeve 53 is stationary on the reciprocating shaft 52. When the reciprocating sleeve 53 moves on the reciprocating shaft 52, it can drive the turning gear 2 to move along the length direction of the drive shaft 32, thereby driving the turning gear 2 to move through the reciprocating sleeve 53.

[0052] Alternatively, the connection between the reciprocating shaft 52 and the reciprocating sleeve 53 can be set as a ball screw connection, which mainly enables the reciprocating sleeve 53 to move along the length direction of the reciprocating shaft 52 when the reciprocating shaft 52 rotates.

[0053] Specifically, refer to Figure 5 , Figure 6 One end of the reciprocating sleeve 53 is inserted into the tooth surface of the turning gear 2, and a connecting ring 531 is fixedly connected to the end of the reciprocating sleeve 53 inserted into the tooth surface of the turning gear 2. The connecting ring 531 is arranged on the outer side of the reciprocating sleeve 53, and an end cap 532 is installed on the turning gear 2 to cover one end of the reciprocating sleeve 53 to prevent the turning gear 2 from separating from the reciprocating sleeve 53. The end cap 532 and the connecting ring 531 are fitted together and abut against each other. The end cap 532 is sleeved on the reciprocating sleeve 53, and the inner ring diameter of the end cap 532 is smaller than the outer ring diameter of the connecting ring 531. The end cap 532 is fixedly connected to the turning gear 2 by screws. The end cap 532 and the connecting ring 531 together restrict the separation between the reciprocating sleeve 53 and the turning gear 2, making the rotational connection between the reciprocating sleeve 53 and the turning gear 2 more stable. A bearing is installed between the connecting ring 531 and the turning gear 2, which makes the rotational connection between the turning gear 2 and the connecting ring 531 smoother.

[0054] Reference Figure 4The reciprocating sleeve 53 also has a guide groove 533 extending along its length on its lower side. A first support plate 54 and a second support plate 55 are fixedly connected to the frame 1. The first support plate 54 is fixedly connected to the reciprocating motor 51, supporting it and ensuring the motor is securely connected to the frame 1. The second support plate 55 is spaced apart from the first support plate 54, and both are arranged along the same straight line. The first support plate 54, the second support plate 55, the drive shaft 32, and the reciprocating shaft 52 are arranged in the same vertical plane. The upper side of the second support plate 55 is inserted into the guide groove 533. The cooperation between the second support plate 55 and the guide groove 533 on the reciprocating sleeve 53 restricts the rotation of the reciprocating sleeve 53, allowing the reciprocating shaft 52 to rotate, thus facilitating the engagement and disengagement of the reciprocating sleeve 53 with the turning gear 2 and the large flywheel 4.

[0055] Additionally, refer to Figure 5 A positioning plate 56 is installed on the other end of the reciprocating sleeve 53, and the positioning plate 56 is arranged on the lower side of the reciprocating shaft 52. Two control switches 57 are installed between the first support plate 54 and the second support plate 55. The control switches 57 can control the forward and reverse rotation of the reciprocating motor 51. The control switches 57 can be proximity switches or contact switches. The two control switches 57 are respectively installed on the opposite surfaces of the first support plate 54 and the second support plate 55. The positioning plate 56 is arranged between the first support plate 54 and the second support plate 55. As the reciprocating sleeve 53 moves, the positioning plate 56 contacts the two control switches 57 respectively. In this embodiment... When the positioning plate 56 contacts the control switch 57 on the second support plate 55, the reciprocating sleeve 53 drives the rotating gear 2 to mesh with the large flywheel 4. At this time, the reciprocating motor 51 is started, and the reciprocating motor 51 rotates in reverse, which allows the reciprocating sleeve 53 to move in the direction where the rotating gear 2 separates from the large flywheel 4. When the positioning plate 56 contacts the control switch 57 on the first support plate 54, the reciprocating motor 51 is started, and the reciprocating motor 51 rotates in the forward direction, which allows the reciprocating sleeve 53 to move in the direction where the rotating gear 2 meshes with the large flywheel 4. When the positioning plate 56 contacts a control switch 57 for the first time, the control switch 57 controls the reciprocating motor 51 to stop. The travel distance of one cycle of the reciprocating motor 51 is the distance between the two control switches 57.

[0056] Reference Figure 2 , Figure 3The gear calibration assembly 6 includes a calibration motor 61 connected to a first reducer 33, and a clutch is installed in the first reducer 33 to ensure that the operation of the calibration motor 61 and the drive motor 31 does not interfere with each other. The calibration motor 61 drives the turning gear 2 to rotate. The angle of the turning gear 2 is adjusted. In this embodiment, the calibration motor 61 drives the turning gear 2 to rotate through the first reducer 33 and the second reducer 34, thus adjusting the angle of the turning gear 2. The calibration motor 61 and the drive motor 31 have different power; the power of the calibration motor 61 is less than that of the drive motor 31. When the calibration motor 61 starts, it drives the turning gear 2 to rotate slightly, thereby adjusting the angle of the turning gear 2 under normal operating conditions so that the arrangement angle of the turning gear 2 matches the arrangement angle of the large flywheel 4.

[0057] The implementation principle of the automatic turning device for a diaphragm compressor in this application embodiment is as follows: Before turning the diaphragm compressor, the angle of the large flywheel 4 is measured by the first angle encoder 7 installed on the diaphragm compressor, and the angle of the turning gear 2 is measured by the second angle encoder 8. Then, the gear calibration component 6 drives the turning gear 2 according to the angle deviation between the large flywheel 4 and the turning gear 2. The calibration motor 61 drives the turning gear 2 to rotate through the first reducer 33, the second reducer 34 and the drive shaft 32 to adjust the angle of the turning gear 2 so that the arrangement angle of the turning gear 2 can mesh with the arrangement angle of the large flywheel 4. Then, the reciprocating component 5 starts, and the reciprocating motor 51 drives the reciprocating sleeve 53 to move. The reciprocating sleeve 53 pushes the turning gear 2 to move along the drive shaft 32, so that the turning gear 2 meshes with the large flywheel 4 through displacement. At this time, the positioning plate 56 on the reciprocating sleeve 53 contacts a control switch 57, and the control switch 57 controls the reciprocating motor 51 to stop. At this time, the turning gear 2 has meshed with the large flywheel 4. Drive motor 31 starts, and under the action of the clutch, drive motor 31 and calibration motor 61 move asynchronously to complete gear shifting. Drive motor 31 drives the turning gear 2 to rotate through the first reducer 33, the second reducer 34, and the drive shaft 32, thereby driving the large flywheel 4 to rotate. The rotation of the large flywheel 4 drives the components in the diaphragm compressor, thus realizing the turning of the diaphragm compressor. After the turning is completed, drive motor 31 stops, and reciprocating motor 51 starts. Reciprocating motor 51 drives the turning gear 2 to disengage from the large flywheel 4 through reciprocating sleeve 53. Afterwards, the diaphragm compressor operates normally.

[0058] By installing an automatic cranking device, the diaphragm compressor can be cranked automatically, eliminating the need for personnel to enter the compressor site for manual cranking. This facilitates accurate cranking, reduces the risk of injury to personnel entering the site, and ensures their health and safety.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
