Description

Technical Field

[0001] This invention relates to the technical field of motor dismantling and transportation, and in particular to an air compressor motor repair device. Background Technology

[0002] After the installation and commissioning of the third-phase air compressors in our factory, the air compressor motors require regular maintenance, including bearing replacement. The air compressor motor weighs 1.5 tons and is installed inside the compressor. Above the motor are the air compressor coolant radiator and two cooling fans, and the top of the compressor contains the exhaust duct, making motor removal extremely difficult during maintenance. Removing the motor requires dismantling the air compressor coolant radiator, cooling fans, compressor housing, and the exhaust duct at the top of the compressor before hoisting it out for maintenance. This work requires multiple people and several days of preparation, resulting in a significant waste of human resources and increased labor intensity for workers.

[0003] The applicant, aiming to save time in motor maintenance and reduce the labor intensity of workers, designed a special tool for air compressor motor maintenance after extensive demonstration and on-site measurement. The tool utilizes the principle of reducing resistance through rolling friction to lay a stable slide rail at the bottom of the air compressor motor, thereby achieving the purpose of moving the motor. The length of the slide rail can be adjusted at will, and in case of emergency stop, the slide rail can be converted into a maintenance platform for easy operation by workers. This tool can save half of the manpower and shorten the maintenance time to 3 / 4 of the original time. Summary of the Invention

[0040] Example 1

[0041] Reference Figure 1 An air compressor motor maintenance device includes a roller device 100, which utilizes the principle of reducing resistance through rolling friction to transport the motor outside the air compressor for maintenance. Multiple roller devices 100 are provided and connected by a connecting device 200, which can be freely spliced ​​according to needs. A limiting device 300 is used to limit the roller devices 100. When the air compressor motor moves to a suitable position, the roller 102 can be positioned to prevent it from rotating, thus changing the roller platform from a transport platform to a maintenance platform, eliminating the need to move the air compressor motor further.

[0042] Specifically, multiple idler roller devices 100 are provided, which are connected by a connecting device 200 to form a platform. When maintenance is required, the bolts of the air compressor coupling are removed to remove the elasticity of the coupling. The motor is lifted using a jack, and one end of the entire idler roller platform is inserted into the air compressor and placed under the motor. The other end is supported by a frame to make the entire idler roller platform more stable. Then, the jack is removed to allow the motor to fall smoothly on the top of the idler roller 102. Then, the motor is pushed to move the motor outside the air compressor.

[0043] Furthermore, the limiting device 300 includes a movably connected locking component 301 and unlocking component 302. The locking component 301 is connected to the roller 102, restricting the rotation of the idler roller 102. The unlocking component 302 is connected to the connecting device 200. When the connecting device 200 is connected to the idler roller device 100, the locking component 301 is unlocked by the unlocking component 302, allowing the idler roller 102 to rotate freely and drive the motor. When the conveyor is placed outside the air compressor, it moves to a suitable position, moves the connecting device 200, and separates the depressurization component 302 from the locking component 301. The locking component 301 connects to the roller 102, restricting the rotation of the roller 102, and can also connect to the idler roller device 100. This allows the idler roller platform to be changed from a transport platform to a maintenance platform without needing to move the air compressor motor.

[0044] In use, the locking component 301 is installed on the idler roller assembly 100 to limit and lock the roller 102. Then, according to the required length, multiple roller assemblies 100 are connected using the connecting device 200. When the connecting device 200 is fully engaged with the idler roller assembly, an idler roller platform is formed, and the locking component 301 is unlocked by the unlocking component 302, allowing the idler roller 102 to rotate freely. The air compressor's coupling bolts are removed to eliminate the elasticity of the coupling. The motor is then lifted using a jack, and one end of the entire idler roller platform is inserted into the air compressor and placed under the motor; the other end is supported by a frame. This makes the entire idler platform more stable; then remove the jack to allow the motor to rest smoothly on top of the idler 102, then push the motor to move it outside the air compressor; move it to a suitable position, move the connecting device 200 to separate the decompression component 302 from the snap-fit ​​component 301. The snap-fit ​​component 301 connects to the roller 102, restricting the rotation of the roller 102, and can also connect to the idler device 100; this allows the idler platform to be changed from a transport platform to a maintenance platform, without needing to continue moving the air compressor motor, and without worrying about the roller 102 slipping during maintenance.

[0045] Example 2

[0046] Reference Figures 1-6 This embodiment is based on the above embodiment.

[0047] Specifically, the roller bracket 101 includes a fixedly connected base 101a, which has a rectangular cross-section and serves as a support; two brackets 101b are provided, symmetrically and vertically arranged at both ends of the base 101a, for mounting the roller 102; and a rotating shaft 101c is fixedly connected at both ends to the two brackets 101b. The roller 102 includes a fixed sleeve 102a fixedly connected to the rotating shaft 101c. The fixed sleeve 102a is annular and can position the roller 102. The system includes a friction sleeve 102b rotatably connected to the fixed sleeve 102a (such as a bearing roller commonly used by those skilled in the art); the friction sleeve 102b has a snap-fit ​​groove 102b-1 on its surface. The snap-fit ​​groove 102b-1 is a cylindrical groove that is circumferentially distributed on the surface of the friction sleeve 102b. The axial direction of the snap-fit ​​groove 102b-1 is parallel to the bearing of the roller 102. The snap-fit ​​groove 102b-1 is connected to the snap-fit ​​assembly 301 to limit the movement of the roller 102.

[0048] Furthermore, the connecting device 200 includes a first connecting member 201, which includes a connecting block 201a fixedly connected to the base 101a. The connecting block 201a is a cuboid, and its bottom surface is parallel to the bottom surface of the base 101a. It also includes a fixing block 201b rotatably connected to the connecting block 201a via a shaft. The fixing block 201b is a cuboid, and its length is greater than the width of the connecting block 201a. The shaft is positioned away from the base 101a. The shaft is perpendicular to the axial direction of the roller 102; and a handle 201c is connected to the fixed block 201b, which can drive the fixed block 201b to rotate 90°. The connecting block 201a is placed between the fixed block 201b and the handle 201c; the base 101a is provided with a first connecting groove 101a-1 to connect with the first connecting member 201. The first connecting groove 101a-1 and the first connecting member 201 are respectively located at opposite ends of the base 101a, which can facilitate the connection between the two roller devices 100. The two parts are connected in pairs; the first connecting groove 101a-1 consists of a connecting hole 101a-11 and a fixing hole 101a-12. The size of the connecting hole 101a-11 is the same as that of the connecting block 201a, and the connecting block 201a can be fully inserted into the connecting hole 102a; the fixing hole 101a-12 has a square cross-section and a length that is the same as that of the fixing block 201b. The fixing hole 101a-12 has an opening for the fixing block 201b to pass through, and the width of the opening of the fixing block 101a-12 is the same as that of the fixing block 201b. The width of the fixed block 201b is consistent, and the fixed block 201b can only be inserted vertically (i.e., the shorter end enters first). After the fixed block 201b is fully inserted into the fixed hole 101a-12, it can rotate 90° within the fixed hole 101a-12. Since the width of the opening of the fixed hole 101a-12 is consistent with the width of the fixed block 201b, after the fixed block 201b rotates 90°, it is blocked by the opening of the fixed hole 101a-12 and cannot come out, so that the roller device 100 performs preliminary positioning and connection.

[0049] Furthermore, the connecting device 200 includes a second connecting member 202, which includes a connecting plate 202a. The connecting plate 202a is a cuboid and includes a first locking block 202b and a second locking block 202c disposed on it. Both the first locking block 202b and the second locking block 202c are trapezoidal protrusions, with the upper base length being greater than the lower base length. When the first locking block 202b and the second locking block 202c are engaged with the base 101a, only... It can go in and out in any direction without falling downwards; the base 101a is provided with a second connecting groove 101a-2 and a third connecting groove 101a-3 connected to it. The second connecting groove passes through the lower end of the bracket 101b. The first locking block 202b cooperates with the second connecting groove 101a-2, and the second locking block 202c cooperates with the third connecting groove 101a-3. The cross-sections of the second connecting groove 101a-2 and the third connecting groove 101a-3 are both trapezoidal, and the length of the upper base is greater than the length of the lower base.

[0050] Preferably, the connecting plate 202a has a groove 202a-1, which is placed between the first locking block 202b and the second locking block 202c to avoid the first connecting member 201. Only when the fixing block 201b rotates 90° and is blocked by the opening of the fixing hole 101a-12, and the fixing block 201b is completely close to the opening of the fixing hole 101a-12, that is, when the handle 201c is completely placed in the groove 202a-1, can the first locking block 202b and the second connecting groove 101a-2, and the second locking block 202c and the third connecting groove 101a-3 be fully connected.

[0051] Furthermore, the unlocking component 302 is provided with a first unlocking member 302a and a second unlocking member 302b. The first unlocking member 302a and the second unlocking member 302b are symmetrically arranged on both sides of the first locking block 202b and are magnetically connected to the locking component 301 arranged on the rotating shaft 101c. The base 101a is symmetrically provided with two through slots 101a-4, which are connected to the second connecting slot 101a-2. When the second connecting member 202 is pushed to connect with the base 101a, the first unlocking member 302a and the second unlocking member 302b pass through the through slots 101a-4 and are magnetically connected to the locking component 301. The locking component 301 is placed between the roller 102 and the bracket 101b, thereby releasing the restriction on the roller 102.

[0052] In use, align the connecting block 201a and the fixing block 201b with the connecting hole 101a-11 and the fixing hole 101a-12 respectively. After both are fully inserted, rotate the handle 201c. The handle 201c can drive the fixing block 201b to rotate 90°. The fixing block 201b is blocked by the opening of the fixing hole 101a-12 and cannot come out, so that the roller device 100 is initially positioned and connected. Then, insert the second connecting piece 202, align the first locking block 202b with the second connecting groove 101a-2, align the second locking block 202c with the third connecting groove 101a-3, and align the groove 202a-1 with the position of the handle 201c. At this time, the first unlocking piece 302a and the second unlocking piece 302b pass through the through groove 101a-4 and are magnetically connected to the locking assembly 301, releasing the restriction on the roller 102. At this time, a roller platform is formed, and the locking assembly 301... 01 The unlocking component 302 is unlocked, and the idler roller 102 can rotate freely. The bolts of the air compressor coupling are removed to remove the elasticity of the coupling. The motor is lifted using a jack, and one end of the entire idler roller platform is inserted into the air compressor and placed under the motor. The other end is supported by a frame to make the entire idler roller platform more stable. Then, the jack is removed to allow the motor to fall smoothly on the top of the idler roller 102. Then, the motor is pushed to move it outside the air compressor. After moving it to a suitable position, the second connecting piece 202 is pulled out, so that the decompression component 302 separates from the snap-fit ​​component 301 and is disengaged from the through groove 101a-4. The snap-fit ​​component 301 is connected to the roller 102, restricting the rotation of the roller 102, and can also be connected to the idler roller device 100. The idler roller platform can be changed from a transport platform to a maintenance platform without continuing to move the air compressor motor, and there is no need to worry about the roller 102 slipping during maintenance.

[0053] Example 3

[0054] Reference Figure 7 and Figure 8 This embodiment is based on the above embodiment.

[0055] Specifically, the idler roller device 100 includes a support leg 103, which is fixedly connected to one of the idler roller brackets 101 as a support roller. One end of the idler roller platform extends into the air compressor and is placed under the motor; the other end is supported by the support leg 103, so there is no need to find something to pad it.

[0056] Furthermore, the snap-fit ​​assembly 301 is disposed between the bracket 101b and the roller 102. Two snap-fit ​​assemblies 301 are provided, symmetrically disposed on the rotating shaft 101c, one of which faces the base 101a.

[0057] Furthermore, the snap-fit ​​assembly 301 includes a snap-fit ​​shell 301a fixedly connected to the rotating shaft 101c. Two snap-fit ​​shells 301a are assembled into a cube with a through groove for accommodating the rotating shaft 101c. The snap-fit ​​shell 301a has an accommodating space inside, which is a cuboid. One end of the snap-fit ​​shell 301a facing the roller 102 has an opening 301a-1 for the telescopic member 301b to extend and retract to connect with the snap-fit ​​groove 102b-1.

[0058] Specifically, the snap-fit ​​assembly 301 includes a telescopic member 301b movably connected to the snap-fit ​​housing 301a. The telescopic member 301b includes a stop block 301b-1 placed inside the snap-fit ​​housing 301a. The stop block 301b-1 is a cuboid, and its length is greater than the length of the opening 301a-1 to ensure that the telescopic member 301b will not detach from the snap-fit ​​housing 301a. The stop block 301b-1 is connected to the snap-fit ​​housing 301a by a first spring 301b-4, which is set in the same direction as the extension rod 301b-2. Three extension rods 301b-2 are fixedly connected to the stop block 301b-1. The extension rods 301b-2 are arranged in an arc, corresponding to the snap-fit ​​groove 102b-1. A ball bearing 301b-3 is connected to the end of the extension rod 301b-2 away from the stop block 301b-1. The ball bearing 301b-3 can reduce friction.

[0059] Specifically, the snap-fit ​​assembly 301 includes a magnetic pusher 301c placed inside the snap-fit ​​housing 301a and movably connected to the telescopic member 301b. The magnetic pusher 301c has two push rods 301c-1 hinged to the inner wall of the snap-fit ​​housing 301a away from the opening 301a-1, and magnetic balls 301c-2 fixedly connected to the push rods 301c-1. The two magnetic balls 301c-2 repel each other. The two push rods 301c-1 are connected by a second spring 301c-3. Under normal conditions, the tension of the second spring 301c-3 can balance the repulsive force of the two magnetic balls 301c-2. The two push rods 301c-1 are arranged in parallel, and the magnetic balls 301c-2 are in contact with the stop block 301b-1. Preferably, except for the two magnetic balls 301a-2, the snap-fit ​​assembly 301 is not magnetic and will not generate attraction or repulsion force on the two magnetic balls 301a-2.

[0060] Furthermore, the ends of the first unlocking member 302a and the second unlocking member 302b away from the first locking block 202b are magnetic, and the magnetic poles on opposite sides are equal but repel each other; when the first unlocking member 302a and the second unlocking member 302b pass through the through groove 101a-4 and are placed at both ends of the locking shell 301a, the first unlocking member 302a and the second unlocking member 302b respectively attract the magnetic balls 301c-2 that are close to them, and the two push rods 301c-1 are deflected, the first spring 301b-4 is reset, the telescopic rod 301b moves towards the magnetic pusher 301c under the action of the first spring 301b-4, the extension rod 301b-2 disengages from the locking groove 102b-1, the friction sleeve 102b is unrestricted, and the roller 102 can rotate freely under the action of external force; when it is necessary to reposition the roller 102, the second connecting member 202 is pulled out, so that the first The first unlocking component 302a and the second unlocking component 302b disengage from the through slot 101a-4, but the second connecting component 202 does not disengage from the base 101a. At this time, the two magnetic balls 301-2 lose the effect of external force and reset under the action of the second spring 301c-3, restoring their initial parallel positions. During the reset process, the magnetic balls 301c-2 will squeeze the telescopic component 301b, pushing the extension rod 301b-2 toward the locking groove 102b-1. When the ball 301b-3 is attached to the friction sleeve 102b, the roller 102 will continue to move slowly due to inertia. Therefore, during the rotation of the roller 102, the ball 301b-3 will definitely roll into the locking groove 102b-1, limiting the friction sleeve 102b, thereby forcing the roller 102 to stop rolling, changing the idler platform from a transportation platform to a maintenance platform, making it convenient for the operator to carry out subsequent maintenance.

[0061] In use, align the connecting block 201a and the fixing block 201b with the connecting hole 101a-11 and the fixing hole 101a-12 respectively. Once both are fully inserted, rotate the handle 201c. The handle 201c will rotate the fixing block 201b 90°, blocking it from exiting the fixing hole 101a-12, thus achieving initial positioning and connection of the roller device 100. Next, insert the second connecting piece 202, aligning the first locking block 202b with the second connecting groove 101a-2, the second locking block 202c with the third connecting groove 101a-3, and the groove 202a-1 with the handle 201c. At this position, the first unlocking member 302a and the second unlocking member 302b pass through the through groove 101a-4 and are placed at both ends of the snap-fit ​​shell 301a. The first unlocking member 302a and the second unlocking member 302b respectively attract the magnetic ball 301c-2 that is close to them, and the two push rods 301c-1 are deflected. The first spring 301b-4 is reset, and the telescopic rod 301b moves toward the magnetic pusher 301c under the action of the first spring 301b-4. The extension rod 301b-2 is disengaged from the snap-fit ​​groove 102b-1, and the friction sleeve 102b is unrestricted. Under the action of external force, the roller 102 can rotate freely.

[0062] When the motor needs maintenance, pull out the second connector 202, causing the first unlocking piece 302a and the second unlocking piece 302b to disengage from the through slot 101a-4, but the second connector 202 does not disengage from the base 101a. At this time, the two magnetic balls 301-2 lose the external force and reset under the action of the second spring 301c-3, restoring their initial parallel position. During the reset process, the magnetic balls 301c-2 will squeeze the telescopic piece 301b, pushing the extension rod 301b-2 toward the latch. When the groove 102b-1 is pushed, and the ball 301b-3 is in contact with the friction sleeve 102b, the roller 102 will continue to move slowly due to inertia. Therefore, during the rotation of the roller 102, the ball 301b-3 will inevitably roll into the groove 102b-1, limiting the friction sleeve 102b and forcing the roller 102 to stop rolling. This changes the idler platform from a transportation platform to a maintenance platform, making it convenient for operators to carry out subsequent maintenance. The roller 102 will not slip, avoiding accidents.
