Dismounting device

Abstract

The utility model relates to the technical field of dismounting devices, in particular to a dismounting device which is provided with a locking hoop, a supporting block is arranged on the locking hoop, a screw hole is formed in the supporting block, the axial direction of the center of the screw hole is consistent with the axial direction of the center of the locking hoop, and an ejection bolt is arranged in the screw hole. When the ejection bolt is rotated, the ejection bolt is gradually pushed forwards along the axial direction, and along with further pushing of the ejection bolt, the ejection bolt gradually applies an upward force to the frequency converter, and the upward force overcomes the bonding force of a sealant between the frequency converter and the rear end cover of the motor. Therefore, the frequency converter starts to move upwards relative to the motor rear end cover. By continuously rotating the ejection bolt and gradually increasing the thrust of the ejection bolt, the frequency converter is gradually and mildly separated from the rear end cover of the motor, so that rough means such as strong prying and smashing which are possibly used in a traditional disassembly method are avoided, and the risk of damage to a frequency converter shell, internal elements and the rear end cover of the motor is remarkably reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of disassembly devices, in particular to a disassembly device. Background Art

[0002] In the motor industry, a permanent magnet integrated machine is a high-efficiency and high-performance motor device, which combines a permanent magnet synchronous motor and a frequency converter. Since the permanent magnet integrated machine works outdoors all year round, it needs to face extreme weather changes, such as heavy rain and large temperature differences. These harsh conditions pose a great threat to the electrical components inside the motor. To ensure the stable operation of the motor and the frequency converter in harsh environments, waterproof treatment at the contact surface is crucial. Generally, high-quality sealant is used for sealing, which can not only effectively block water penetration, protect the internal circuit from erosion, but also enhance the overall sealing of the device and extend its service life.

[0003] However, while this waterproof measure provides protection, it also poses certain challenges to subsequent maintenance work. When the permanent magnet integrated machine needs to replace the frequency converter due to a fault or upgrade, the cured sealant becomes a problem. It not only increases the difficulty of disassembly, but also easily causes damage to the frequency converter or other components during forced disassembly. Summary of the Invention

[0004] To solve the above problems, the present application provides a disassembly device, which is provided with a locking clamp. A support block is arranged on the locking clamp, a threaded hole is arranged on the support block, and the axial direction of the center of the threaded hole is the same as the axial direction of the center of the locking clamp. A jacking bolt is arranged in the threaded hole.

[0005] In one embodiment, the support block is fixedly installed on the locking clamp. There are at least two support blocks, and the support blocks are evenly distributed on the locking clamp.

[0006] In one embodiment, the locking clamp includes a first clamp and a second clamp. The first clamp and the second clamp are hinged. Locking mounting seats are arranged on the first clamp and the second clamp. The locking mounting seats are arranged in a U shape, and a T-shaped bolt is arranged in the locking mounting seats.

[0007] In one embodiment, the T-shaped bolt includes a rotating shaft, an adjusting rod, and a locking member. The rotating shaft is rotatably installed on the locking mounting seat, and the adjusting rod can be placed in the U-shaped groove of the locking mounting seat.

[0008] In one embodiment, the locking member is threadedly connected to the adjusting rod.

[0009] In one embodiment, locking fins are arranged on the locking member.

[0010] In one embodiment, a backing plate is further provided, and the backing plate is used to be placed under the support block.

[0011] In one embodiment, the locking member is a lock nut.

[0012] The beneficial effects of the present utility model are as follows:

[0013] A disassembly device of the present application is provided with a locking clamp. A support block is arranged on the locking clamp, a threaded hole is arranged on the support block, and the axial direction of the center of the threaded hole is consistent with the axial direction of the center of the locking clamp. A jacking bolt is arranged in the threaded hole. The locking clamp is used to lock onto the frequency converter. The support block serves as a support structure for the jacking bolt. When the jacking bolt is rotated, due to the thread action of the threaded hole, the jacking bolt will gradually advance forward along the axis. As the jacking bolt further advances, it will gradually exert an upward force on the frequency converter. This upward force will overcome the adhesive force of the sealant between the frequency converter and the motor rear end cover, so that the frequency converter starts to move upward relative to the motor rear end cover. By continuously rotating the jacking bolt and gradually increasing its thrust, the frequency converter will be gradually and gently separated from the motor rear end cover, avoiding the rough means such as forced prying and hammering that may be used in traditional disassembly methods, and significantly reducing the risk of damage to the frequency conversion housing, internal components, and the motor rear end cover.

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clear and understandable, the following further details this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0024] It should be noted that the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality" means two or more, unless otherwise specifically defined.

[0025] As Figure 1 , 4 shown, a disassembly device is provided with a locking clamp 1, a support block 2 is arranged on the locking clamp 1, a threaded hole 3 is arranged on the support block 2, the axial direction of the center of the threaded hole 3 is the same as the axial direction of the center of the locking clamp 1, and a jacking bolt 4 is arranged in the threaded hole 3.

[0026] Specifically, during use, first place the locking clamp 1 accurately at an appropriate position on the outer shell of the frequency converter 5 and firmly lock it on the frequency converter 5 to ensure that during the disassembly process, the relative position between the locking clamp 1 and the frequency converter 5 remains stable and will not slide or loosen due to external forces. The support block 2, as the support structure of the jacking bolt 4, is fixed on the locking clamp 1. The threaded hole 3 on the support block 2 provides an accurate axial guide for the jacking bolt 4 to ensure that the jacking bolt 4 can move along the predetermined axial direction when rotated, that is, in the direction consistent with the central axis of the locking clamp 1 and the frequency converter 5. When the jacking bolt 4 is rotated, due to the thread action of the threaded hole 3, the jacking bolt 4 will gradually advance forward along the axial direction. Since the front end of the jacking bolt 4 directly contacts and acts on the rear end cover of the motor 6, as the jacking bolt 4 further advances, it will gradually apply an upward force to the frequency converter 5. This upward force will overcome the adhesive force of the sealant between the frequency converter 5 and the rear end cover of the motor 6, so that the frequency converter 5 starts to move upward relative to the rear end cover of the motor 6. By continuously rotating the jacking bolt 4 and gradually increasing its thrust, the frequency converter 5 will be gradually and gently separated from the rear end cover of the motor 6, avoiding the rough means such as forced prying and hitting that may be used in traditional disassembly methods, and significantly reducing the risk of damage to the outer shell of the frequency converter 5, internal components and the rear end cover of the motor 6.

[0027] As Figure 1 , 3 shown, the support block 2 is fixedly installed on the locking clamp 1, there are at least two support blocks 2, and the support blocks 2 are evenly distributed on the locking clamp 1.

[0028] Specifically, the support block 2 is welded to the locking clamp 1, and the uniform distribution of multiple support blocks 2 provides better stability for the entire disassembly device. Multiple support blocks 2 jointly support the ejection bolt 4 to ensure that during the disassembly process, the ejection force can be evenly transmitted to the inverter 5, avoiding deflection or shaking caused by uneven force at a single point, thereby protecting the integrity of the inverter 5 and the motor 6. Dispersing the ejection force to multiple support blocks 2 can reduce the local stress on each support block 2, help prevent the support block 2 from being damaged due to overload, and also reduce the pressure concentration on the inverter 5 housing, reducing the potential risk of indentation or deformation.

[0029] like Figure 1 As shown, the locking clamp 1 includes a first clamp 11 and a second clamp 12, the first clamp 11 and the second clamp 12 are hinged, and a locking mounting seat 13 is provided on the first clamp 11 and the second clamp 12, the locking mounting seat 13 is U-shaped, and a T-bolt 14 is provided in the locking mounting seat 13.

[0030] Specifically, the first clamp 11 and the second clamp 12 are connected by a hinged manner, so that the locking clamp 1 can flexibly adapt to inverters 5 of different sizes and shapes. The operator can adjust the angle between the first clamp 11 and the second clamp 12 according to the actual size of the inverter 5, so as to achieve a tight covering and effective fixation of the inverter 5. Due to the hinged design, the installation and removal process of the locking clamp 1 becomes faster and more convenient. The operator can quickly unfold the locking clamp 1 around the inverter 5 and fix it through the locking mounting seat 13 without complicated positioning and adjustment steps. The locking mounting seat 13 is set in a U-shape, providing a stable installation foundation for the T-bolt 14. The T-bolt 14 can provide a greater locking force and a better anti-loosening effect during the locking process through its special shape design, ensuring that the locking clamp 1 can be firmly fixed on the inverter 5 during the disassembly process, preventing disassembly failure or equipment damage caused by looseness. The combined use of the U-shaped locking mount 13 and the T-shaped bolt 14 not only improves the reliability of locking, but also enhances the structural strength of the entire locking clamp 1, which enables the disassembly device to remain stable when dealing with a large ejection force and is not prone to deformation or damage.

[0031] like Figure 1 , 2 As shown, the T-bolt 14 includes a rotating shaft 141 , an adjusting rod 142 , and a locking member 143 . The rotating shaft 141 is rotatably mounted on the locking mounting seat 13 , and the adjusting rod 142 can be placed in a U-shaped groove of the locking mounting seat 13 .

[0032] Specifically, the moving shaft 141 is rotatably mounted on the locking mounting seat 13 so that the T-bolt 14 can rotate freely, and the operator adjusts its position by rotating the T-bolt 14. The adjusting rod 142 can be placed in the U-shaped groove of the locking mounting seat 13 and can move along the trajectory of the U-shaped groove, so as to achieve close fitting and effective locking of the frequency converter 5. By adjusting the position of the adjusting rod 142 in the U-shaped groove, the operator can adjust the magnitude and position of the locking force as needed to adapt to frequency converters 5 of different sizes and shapes. The locking member 143 can usually be a locking nut, a locking pin or other forms of fastening devices, which are used to fix the adjusting rod in the required position. After the adjusting rod 142 is adjusted to the appropriate position, tightening the locking member 143 can ensure the stable locking of the T-bolt 14 and prevent loosening during the disassembly process.

[0033] As Figure 2 shown, the locking member 143 is threadedly connected to the adjusting rod 142.

[0034] Specifically, the threaded connection allows the locking member 143 to be gradually tightened along the thread of the adjusting rod 142, so as to achieve close fitting of the frequency converter 5 and prevent accidental detachment or damage caused by loosening during the disassembly process. By rotating the locking member 143, the operator can adjust the magnitude of the locking force as needed.

[0035] As Figure 1 、 2 shown, the locking member 143 is provided with locking fins 144.

[0036] Specifically, the locking fins 144 are fixedly installed on the locking member 143. The locking fins 144 have a large surface area, and the operator can more easily grasp and rotate them without using additional tools or applying excessive force, making the operation more convenient and labor-saving.

[0037] As Figure 3 、 4 shown, a backing plate 7 is further provided, and the backing plate 7 is used to be placed under the support block 2.

[0038] Specifically, the main function of the backing plate 7 is to serve as a layer of buffer and protective layer and is placed between the support block 2 and the motor 7. When the ejector bolt 4 rotates and applies an ejection force, the backing plate 7 can absorb and disperse these forces, preventing the motor 6 from directly bearing excessive pressure or friction, thereby avoiding damage to the motor 6 housing or internal components. The use of the backing plate 7 reduces the risk of motor damage caused by improper rotation of the ejector bolt 4, makes the disassembly process safer and more reliable, reduces potential safety hazards, and protects the motor 6 from unnecessary physical impact and wear.

[0039] The beneficial effects of the present application compared with the prior art:

[0040] A disassembly device of the present application is provided with a locking clamp 1. A support block 2 is arranged on the locking clamp 1. A threaded hole 3 is arranged on the support block 2. The axial direction of the center of the threaded hole 3 is consistent with the axial direction of the center of the locking clamp 1. A jacking bolt 4 is arranged in the threaded hole 3. The locking clamp 1 is used to lock onto the frequency converter 5. The support block 2 serves as a support structure for the jacking bolt 4. When the jacking bolt 4 is rotated, due to the threading effect of the threaded hole 3, the jacking bolt 4 will gradually advance forward along the axis. As the jacking bolt 4 further advances, it will gradually exert an upward force on the frequency converter 5. This upward force will overcome the adhesive force of the sealant between the frequency converter 5 and the rear end cover of the motor 6, thereby causing the frequency converter 5 to start moving upward relative to the rear end cover of the motor 6. By continuously rotating the jacking bolt 4 and gradually increasing its thrust, the frequency converter 5 will be gradually and gently separated from the rear end cover of the motor 6, avoiding the rough means such as forced prying and hitting that may be used in traditional disassembly methods, and significantly reducing the risk of damage to the outer shell of the frequency converter 5, internal components, and the rear end cover of the motor 6.
