During long-term operation, the motor pulley is easily affected by friction, vibration, and environmental factors, and is prone to problems such as wear, cracks, or local damage. After the pulley is damaged, the traditional disassembly method mainly relies on manual use of various tools for violent disassembly, which is not only laborious and time-consuming, but also easily causes secondary damage to the transmission shaft and other related components, and even poses safety hazards. Especially in narrow spaces or when the equipment installation position is complex, manual disassembly is often difficult to operate, resulting in extremely low disassembly efficiency. Summary of the Invention

[0032] Embodiment

[0033] Such as Figures 1 to 6As shown in the figure, a power pulley decoupling device proposed by the present invention includes a motor 9. An output shaft 91 is provided on the motor 9, and a pulley 94 is mounted on the output shaft 91. A clamping sleeve is fixedly sleeved on the output shaft 91, and the clamping sleeve is arranged between the pulley 94 and the clamping sleeve 71. Its function is that after the cylinder 62 abuts against the output shaft 91, the force that the output shaft 91 is abutted against can act on one end of the entire motor 9, avoiding damage to the internal components of the motor when the output shaft 91 is strongly abutted by the piston rod of the cylinder 62. A support base 3 is provided at the bottom of the motor 9. An arc-shaped groove 31 that is in close contact with and allows the snap ring 4 to slide is formed at the top of the support base 3, and the arc-shaped groove 31 supports the sliding of the snap ring 4. One end of the support base 3 is connected to a connecting plate 2. A tray 8 for receiving the pulley 94 is fixedly connected to a surface of the connecting plate 2 away from the support base 3. The tray 8 is installed directly below the pulley 94. When the piston rod of the cylinder 62 retracts, the pulley 94 will completely disengage from the piston rod and fall into the tray 8. An arc-shaped groove is formed at the top of the tray 8, which is used to prevent the pulley 94 that falls into it from shaking. Its shape is used to clamp the pulley 94 to ensure that it can be clamped after falling. A pair of support rods 1 are fixedly connected to a surface of the connecting plate 2 away from the support base 3. A pair of snap rings 4 are sleeved on the motor 9, and a pair of support plates 6 are fixedly connected to the middle of the support rods 1.

[0034] In addition, as Figure 1 , Figure 2 and Figure 4 shown, a sliding mechanism for horizontally moving the motor 9 is provided on the snap ring 4. The sliding mechanism includes a U-shaped frame 41 fixedly connected to the snap ring 4. A limiting rod 42 is fixedly connected inside the U-shaped frame 41. A return spring 43 is movably sleeved on the limiting rod 42. A pair of support blocks 44 that are slidably sleeved with the corresponding limiting rods 42 are fixedly connected to the upper surface of the support base 3. One end of the return spring 43 is fixedly connected to the inner wall of the U-shaped frame 41, and the other end of the return spring 43 is fixedly connected to the support block 44.

[0035] It should be noted that, as Figures 2 to 6As shown in the figure, a pushing mechanism for disengaging the pulley 94 from the output shaft 91 is provided on the pallet 6. The pushing mechanism includes a pair of support rods 1. A pair of pallets 6 are fixedly connected inside the support rods 1. Card slots 61 are formed on the pallets 6, and the card slots 61 are fixedly connected to the air cylinders 62. An air cylinder 62 is fixedly connected inside the card slot 61. A T-shaped card slot 92 is formed at the end of the output shaft 91 away from the motor 9. A T-shaped pin 93 is clamped inside the T-shaped card slot 92. The T-shaped pin 93 is used to clamp the pulley 94 installed inside the output shaft 91 to ensure that the output shaft 91 can drive the pulley 94 without slipping after rotation. An installation hole 95 that is movably sleeved with the output shaft 91 is formed in the middle of the pulley 94. A positioning slot 96 that is clamped by the T-shaped pin 93 is formed inside the installation hole 95. The positioning slot 96 and the T-shaped pin 93 are clamped with each other, so that the output shaft 91 can drive the pulley 94 without slipping after rotation. A plurality of pulley grooves 941 that are linearly arranged and used to clamp the belt are formed on the pulley 94. As a key component for fixing the belt pulley, the size and radian of the pulley grooves 941 are both to ensure sufficient and uniform contact area when fixing the belt, enhance the fixing effect, and reduce secondary damage to the wheel body caused by uneven local stress.

[0036] Further, as Figure 1 shown, one end of the pair of support rods 1 away from the connecting plate 2 is fixedly connected with an end frame 5. A plurality of reinforcing plates 51 that are linearly arranged are fixedly connected to the top of the end frame 5. The reinforcing plates 51 significantly improve the overall strength of the bracket by increasing the force-bearing area and dispersing stress. At the same time, it can effectively limit the relative displacement of the components of the end frame 5 and enhance the stability of the bracket. In addition, it can also assist the end frame 5 to better distribute the load borne, avoiding excessive local load. Support legs 52 are fixedly connected to the bottoms of both ends of the end frame 5.

[0037] Still further, as Figure 1 、 Figure 2 、 Figure 5 and Figure 6 shown, a mounting seat 7 is connected to the surface of the connecting plate 2 close to the pulley 94 by bolts. A bushing 71 that abuts against the snap ring 4 is fixedly connected to the surface of the mounting seat 7 away from the connecting plate 2. The bushing 71 is used to clamp the pulley 94 to ensure that the pulley 94 can be disassembled easily, safely and quickly.

[0038] The present application provides a decoupling method for a power pulley decoupling device. As Figure 1 - Figure 6 shown, it includes the following steps:

[0039] S1. Apply a thrust to the output shaft 91. When starting to disassemble the pulley 94, start the air cylinder 62, and its piston rod pushes the output shaft 91 to make the pulley 94 abut against the end of the bushing 71;

[0040] S2. When the pulley 94 and the output shaft 91 are separated and the old pulley 94 is collected, the output shaft 91 continues to move out of the pulley 94, and the pulley 94 falls onto the piston rod. After the cylinder 62 retracts, it falls into the tray 8;

[0041] S3. When the cylinder 62 is reset and ready to install a new pulley 94, until the output shaft of the motor 9 is not under force, the U-shaped frame 41, under the action of the return spring 43, drives the snap ring 4 and the motor 9 to reset;

[0042] S4. When the replacement of the new pulley 94 is completed, just install the new pulley 94 on the output shaft 91 to finally restore the function.

[0043] In this embodiment, when it is necessary to quickly disassemble the pulley 94 from the output shaft 91, just start the cylinder 62 on a pair of support plates 6. After the cylinder 62 is started, the piston rod pushes the output shaft 91, and the output shaft 91 will drive the motor 9 and a pair of snap rings 4 to slide in the arc-shaped groove 31. When the output shaft 91 moves, it will also drive the pulley 94 to move until the pulley 94 abuts against the end of the bushing 71. At this time, the output shaft 91 will continue to move until the output shaft 91 completely disengages from the mounting hole 95 in the pulley 94. Immediately afterwards, the pulley 94 will fall downward under the action of gravity onto the piston rod of the cylinder 62, and the cylinder 62 retracting the piston rod can make the pulley 94 fall into the tray 8 for the staff to handle.

[0044] When the piston rod of the cylinder 62 abuts against the output shaft 91 to disengage it from the inside of the pulley 94, at the same time, a pair of snap rings 4 will drive a pair of U-shaped frames 41 to move, and the U-shaped frames 41 will drive the internal limit rods 42 to slide along the support blocks 44. Until the output shaft 91 is no longer abutted by the piston rod of the cylinder 62, at this time, the U-shaped frame 41, through the elastic thrust of the return spring 43, makes the U-shaped frame 41 drive the snap ring 4 and the internal motor 9 to slide along the arc-shaped groove 31 to the original position. Finally, install the new pulley 94 on the output shaft 91, which is safe, fast and efficient.

[0045] The preferred embodiments of the present invention described above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only the specific implementation manners. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments to better explain the principle and practical application of the present invention, so that those skilled in the relevant technical field can well understand and utilize the present invention. The present invention is only limited by the claims and their full scope and equivalents.
