Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor technology, and in particular to an automatic turning mechanism. Background Technology
[0002] Diaphragm compressors are widely used in the hydrogen energy industry due to their excellent sealing and high compression ratio. Because of their unique membrane structure, diaphragm compressors require manual rotation to release oil pressure before restarting after a shutdown. Traditionally, this rotation is done manually using a crank handle to rotate the flywheel at low speed.
[0003] Commercially available automatic turning mechanisms typically use a motor to drive a gear pair, which in turn rotates the crankshaft. The crankshaft then drives a flywheel to achieve the turning purpose. This structure uses gear transmission and requires a series of components, including a frame, gear pair, drive assembly, and transmission components that control engagement and disengagement, resulting in a relatively large footprint and size.

[0036] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0037] According to some embodiments of this utility model, refer to Figures 1 to 3An automatic turning mechanism is mounted on the diaphragm compressor 100. The automatic turning mechanism includes a base 200, a turning motor 230, a pneumatic clutch 250, and a reducer 240. The turning motor 230 is mounted on the base 200. The pneumatic clutch 250 includes a first gear 251, a second gear 252, and a chassis 260. The first gear 251, second gear 252, and chassis 260 are coaxially arranged. The first gear 251 is located behind the second gear 252, with its tooth surfaces facing forward. The second gear 252's tooth surfaces face backward. The chassis 260 is mounted on the base 200. A speed reducer 240 is mounted on a base 200. The input end of the speed reducer 240 is connected to the output end of a turning gear motor 230. The output end of the speed reducer 240 is fixedly connected to a first gear disc 251. A second gear disc 252 is fixedly mounted on a drive component 120 of a diaphragm compressor 100. The first gear disc 251 passes through and is rotatably connected to a chassis 260. Venting or venting the chassis 260 allows the first gear disc 251 and the second gear disc 252 to mesh or separate. A spring 280 is provided inside the chassis 260. The two ends of the spring 280 are connected to the chassis 260 and the first gear disc 251, respectively, and the spring 280 is kept in a compressed state.
[0038] When the compressor needs to be rotated, the chassis 260 is vented, causing the first gear 251 to move forward and engage with the second gear 252. After the rotation motor 230 is started, it outputs torque to the reducer 240. The reducer 240 drives the first gear 251 and the second gear 252 to rotate, thereby driving the drive component 120 of the diaphragm compressor 100 to rotate and reset the diaphragm compressor 100 to release the oil pressure. Then, the chassis 260 is de-vented, and under the action of the spring 280, the first gear 251 moves backward and separates from the second gear 252.
[0039] The automatic turning mechanism has a simple and reliable structure, and occupies a small area and volume, making it easy to assemble and move.
[0040] According to some embodiments of this utility model, refer to Figures 1 to 3 The drive component 120 includes a main motor 121, a drive wheel 122, a driven wheel 123, and a belt 124. The output end of the main motor 121 is fixedly connected to the drive wheel 122, and the driven wheel 123 is fixedly connected to the input end of the compressor main unit 101 of the diaphragm compressor 100. The belt 124 is respectively sleeved on and meshed with the drive wheel 122 and the driven wheel 123. In this embodiment, the driven wheel 123 is the flywheel of the compressor main unit 101. By rotating the driven wheel 123, the diaphragm compressor 100 can be rotated and reset to relieve oil pressure. It is only necessary to calculate the torque and speed required for rotation to achieve the purpose of rotation by rotating the flywheel at a set rotation speed.
[0041] Furthermore, refer to Figure 3 The drive component 120 also includes a pressure cover 130 and a coupling 140. The pressure cover 130 is located inside and fixedly connected to the driven wheel 123, and is coaxially arranged with the driven wheel 123. The coupling 140 is fixedly connected to the pressure cover 130 and the second gear disc 252. When the turning motor 230 drives the second gear disc 252 to rotate, it can drive the driven wheel 123 to rotate, thereby turning and resetting the diaphragm compressor 100 to release oil pressure. Preferably, the pressure cover 130 and the coupling 140 are fixedly connected by elastic cylindrical pins 150, which can provide a certain degree of shock absorption when the pressure cover 130 and the coupling 140 are relatively fixed. The coupling 140 and the second gear disc 252 are fixedly connected by fixing bolts 160.
[0042] According to some embodiments of this utility model, refer to Figure 1 The base 200 includes a support platform 210, a support seat 220, and an adjusting bolt. The support seat 220 has multiple first through holes spaced apart in the vertical direction, and the support platform 210 has a second through hole. The adjusting bolt passes through both the second through hole and one of the first through holes to fix the support platform 210 and the support seat 220 together. The turning gear motor 230, the reducer 240, and the chassis 260 are all mounted on the support platform 210. Because the multiple first through holes are spaced apart in the vertical direction, meaning that the heights of the different first through holes are different, the adjusting bolt can be inserted through different first through holes to make the second through hole match the different first through holes, thereby adjusting the height of the support platform 210 to accommodate compressors with different shaft heights.
[0043] According to some embodiments of this utility model, refer to Figure 4 The main motor 121 is a dual-shaft motor, having a first extended shaft and a second extended shaft. The first and second extended shafts are coaxially arranged and fixedly connected. The second extended shaft is fixedly connected to the drive wheel 122, and the first extended shaft is fixedly connected to the second gear disc 252 via a coupling 140. The turning motor 230 can drive the first gear disc 251 to rotate via a reducer 240, thereby driving the second gear disc 252 to rotate, which in turn drives the first and second extended shafts to rotate, thereby driving the drive wheel 122 and the driven wheel 123, realizing the turning and resetting of the diaphragm compressor 100 to release oil pressure.
[0044] According to some embodiments of this utility model, refer to Figure 5The drive unit 120 includes a main motor 121, which is a dual-shaft motor. The main motor 121 has a first extended shaft and a second extended shaft. The second extended shaft is fixedly connected to the input end of the compressor main unit 101 of the diaphragm compressor 100. The first extended shaft is fixedly connected to the second gear disc 252 through a coupling 140. The turning motor 230 can drive the first gear disc 251 to rotate through the reducer 240, thereby driving the second gear disc 252 to rotate, which in turn drives the first extended shaft to rotate and reset the diaphragm compressor 100 to release oil pressure.
[0045] According to some embodiments of this utility model, refer to Figure 6 The end of the first toothed disc 251 away from the second toothed disc 252 is inserted into the inner cavity of the chassis 260. An air cavity 271 is formed between the end of the first toothed disc 251 away from the second toothed disc 252 and the bottom of the chassis 260. The chassis 260 is provided with an air inlet 272 and an air outlet 273 that communicate with the air cavity 271.
[0046] According to some embodiments of this utility model, refer to Figure 6 The air inlet 272 is connected to the first pipe, and the air outlet 273 is equipped with a vent valve. When the first pipe supplies air to the air chamber 271 through the air inlet 272, the air pressure can push the first toothed disc 251 to move closer to the second toothed disc 252 and engage with it. When the vent valve is opened, the air pressure in the air chamber 271 decreases, and under the action of the spring 280, the first toothed disc 251 moves away from the second toothed disc 252, thereby disengaging from it.
