Description

Technical Field

[0001] This disclosure relates to the field of power module maintenance technology, and more specifically, to an auxiliary device for disassembling and assembling power modules. Background Technology

[0002] Currently, among the major converter failures, power module damage is the most costly. Furthermore, due to the high value of power modules and their difficulty in on-site storage, they are not typically stored in the field for extended periods. This results in prolonged vehicle downtime and significant losses when power modules fail. When removing or installing power modules from the converter housing, forklifts are often used. However, the lack of necessary safety measures easily leads to instability and collisions, making the operation highly dangerous, compromising personnel safety, and resulting in a high rate of component damage and unnecessary waste.

[0003] In related technologies, a disassembly and assembly vehicle is used to disassemble and assemble the power module in order to improve the efficiency of disassembly and assembly. However, when the ground is uneven, the mounting plate and support on the disassembly and assembly vehicle cannot fully fit the reactive power compensation device. This will only cause the highest end of the mounting plate to contact the lower surface of the reactive power compensation device, resulting in uneven stress on the support and failure to provide effective support, which will affect the safety of the disassembly and assembly operation. Utility Model Content

[0004] The purpose of this disclosure is to provide a power module auxiliary disassembly and assembly device that improves the safety during the power module disassembly and assembly process.

[0005] To achieve the above objectives, this disclosure provides a power module auxiliary disassembly and assembly device, which includes: a vehicle body; a support platform disposed on the vehicle body; and a support assembly and a loading platform. The support assembly includes a drive structure and a plurality of telescopic members, which are connected between the support platform and the loading platform. The drive structure is used to drive the plurality of telescopic members to extend and retract, so that the loading platform is arranged at an angle relative to the support platform.

[0006] Optionally, the support assembly further includes a ball joint connector, which includes a ball and a ball seat, the ball seat being connected to the support platform and the ball being connected to the center of the loading platform.

[0007] Optionally, the support assembly includes at least three telescopic members, which are evenly spaced along the circumferential intervals of the loading platform.

[0008] Optionally, the telescopic component is configured as a support cylinder.

[0009] Optionally, the power module auxiliary disassembly and assembly device further includes an integrated plate, which is disposed on the support platform. The support cylinder includes a cylinder barrel and a piston rod. The cylinder barrel is connected to the integrated plate, and the piston rod is connected to the loading platform. The drive structure includes an oil storage chamber and multiple oil passages. The integrated plate has the oil storage chamber and multiple oil passages formed inside it. The multiple oil passages are respectively connected to the oil storage chamber and the corresponding cylinder barrel.

[0010] Optionally, the power module auxiliary disassembly and assembly device further includes a sealing component for sealing the oil storage chamber.

[0011] Optionally, the integrated plate has an adjustment hole communicating with the oil storage cavity. The sealing assembly includes an adjustment rod and a stop plug. The adjustment rod is disposed in the adjustment hole, and the stop plug is slidably disposed in the oil storage cavity. The adjustment rod is used to push the stop plug to slide to block the oil storage cavity.

[0012] Optionally, the adjusting rod includes a screw and a slide rod, the slide rod is slidably disposed in the adjusting hole, the stop plug is fixedly connected to one end of the slide rod, the other end of the slide rod is provided with a threaded hole, and the screw is threadedly connected to the threaded hole.

[0013] Optionally, a limiting element is provided in the adjusting hole, the limiting element forming a limiting hole, and the screw passes through the limiting hole and extends into the threaded hole to be threadedly connected to the threaded hole.

[0014] Optionally, a limiting frame is provided on the side of the loading platform away from the bearing platform, and the limiting frame is configured to form a limiting space for limiting the power module.

[0015] Optionally, the integrated board is circular and has a toothed structure arranged circumferentially. The power module auxiliary disassembly and assembly device further includes a worm gear, which is connected to the toothed structure in a transmission manner.

[0016] Optionally, the power module auxiliary disassembly and assembly device further includes an operating handwheel, which is sleeved on the worm and fixedly connected to the worm.

[0017] Optionally, the power module auxiliary disassembly and assembly device includes a lifting assembly, and the support platform is movably mounted on the vehicle body via the lifting assembly.

[0018] With the above technical solution, when it is necessary to disassemble or assemble a power module that is on an inclined surface, the vehicle body moves to a position close to the power module. Since the angle between the support platform and the vehicle body is fixed, the drive structure can drive multiple telescopic components set between the loading platform and the support platform to extend and retract. This allows the loading platform to adjust its posture relative to the support platform according to the inclination angle of the ground, ensuring that the loading platform is always in a horizontal state. This enables the power module to be loaded horizontally onto the loading platform, achieving disassembly of the power module on uneven ground. This avoids the instability caused by the tilt during the movement of the power module to the vehicle body, which could lead to collisions and damage to the power module.

[0019] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0026] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0027] In this disclosure, unless otherwise stated, the directional terms "inner" and "outer" refer to "inner" and "outer" relative to the contour of the corresponding component itself. The directional terms "upper" and "lower" generally refer to "upper" and "lower" relative to each other in the direction of gravity when the corresponding component is in use. Furthermore, the use of terms such as "first" and "second" is for distinguishing different components and does not indicate sequence or importance. In addition, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same elements. Those skilled in the art should understand that the above definitions are for explanation and illustration only and should not be construed as limiting the present disclosure.

[0028] According to a specific embodiment of this disclosure, refer to Figures 1 to 3 As shown, a power module auxiliary disassembly and assembly device is provided. The power module auxiliary disassembly and assembly device includes: a vehicle body 1; a support platform 2, which is disposed on the vehicle body 1; and a support assembly and a loading platform 3. The support assembly includes a drive structure 41 and multiple telescopic members. The multiple telescopic members are connected between the support platform 2 and the loading platform 3. The drive structure 41 is used to drive the multiple telescopic members to extend and retract, so that the loading platform 3 is arranged at an angle relative to the support platform 2.

[0029] With the above technical solution, when it is necessary to disassemble or assemble the power module on an inclined surface, the vehicle body 1 moves to a position close to the power module. Since the angle between the support platform 2 and the vehicle body 1 is fixed, the drive structure 41 can drive multiple telescopic components set between the loading platform 3 and the support platform 2 to extend and retract. This allows the loading platform 3 to adjust its posture relative to the support platform 2 according to the inclination angle of the ground, so that the loading platform 3 can always be adjusted to a horizontal state. This enables the power module to be horizontally loaded onto the loading platform 3, achieving the disassembly of the power module on uneven ground. This avoids the situation where the center of gravity is unstable due to the inclination during the movement of the power module to the vehicle body 1, which could easily cause it to be bumped and damaged.

[0030] In the embodiments provided in this disclosure, reference is made to Figure 1 and Figure 2 As shown, the support assembly may further include a ball connector 43, which includes a ball 431 and a ball seat 432. The ball seat 432 is connected to the support platform 2, and the ball 431 is connected to the center of the loading platform 3. The ball connector 43 allows the connected components to rotate and oscillate in multiple directions, providing degrees of freedom of movement in three-dimensional space. Thus, by placing the ball connector 43 between the support platform 2 and the loading platform 3, the ball can rotate synchronously when the loading platform 3 rotates, absorbing the impact and vibration during the rotation of the loading platform 3, improving the stability of the loading platform 3's rotation, and preventing damage to the structure of the loading platform 3. Therefore, the loading platform 3 can better adapt to rotation at different angles and positions.

[0031] In the embodiments provided in this disclosure, reference is made to Figure 1 and Figure 2 As shown, the support assembly may include at least three telescopic members, which are evenly spaced along the circumference of the loading platform 3. These three support members provide stable support for the loading platform 3, ensuring its stability during adjustment and preventing tilting or swaying. Simultaneously, the extension / retraction amount of each telescopic member can be adjusted independently relative to each other to keep the loading platform 3 always in a horizontal position.

[0032] In other embodiments of this disclosure, the number of telescopic components may be multiple, such as four or more, to adapt to the structure of the loading platform 3. This disclosure does not impose specific limitations on this.

[0033] In the embodiments provided in this disclosure, the telescopic member can be constructed as a telescopic rod. In this case, the drive structure 41 can be constructed as a cylinder, and the number of cylinders is equal to the number of telescopic rods and corresponds one-to-one. In this way, each cylinder drives its corresponding telescopic rod to extend or retract, thereby adjusting the posture of the loading platform 3.

[0034] In the embodiments provided in this disclosure, reference is made to Figure 1 and Figure 2 As shown, the telescopic component can be constructed as a support cylinder 42. In this way, the support cylinder 42 can provide a large load-bearing capacity to accommodate the support and lifting of heavy loads such as the power module. Furthermore, the extension and retraction of the support cylinder 42 can be precisely controlled via the hydraulic system to achieve precise adjustment of the tilt angle of the loading platform 3, ensuring the balance of the power module. Additionally, the support cylinder 42 allows for automated or semi-automated adjustment, improving work efficiency.

[0035] In the embodiments provided in this disclosure, reference is made to Figure 3As shown, the power module auxiliary disassembly and assembly device also includes an integrated plate 5, which is mounted on the support platform 2. The support cylinder 42 includes a cylinder barrel 421 and a piston rod 422. The cylinder barrel 421 is connected to the integrated plate 5, and the piston rod 422 is connected to the loading platform 3. The drive structure 41 includes an oil storage chamber 411 and multiple oil passages 412. The integrated plate 5 has an oil storage chamber 411 and multiple oil passages 412 inside, and the multiple oil passages 412 are respectively connected to the oil storage chamber 411 and the corresponding cylinder barrel 421. The oil storage chamber 411 and the oil passages 412 are filled with hydraulic oil. In this way, when it is necessary to control the extension of the support cylinder 42, the hydraulic oil in the oil storage chamber 411 can be supplied to the corresponding cylinder barrel 421 through the oil passages 412. The hydraulic oil enters the cylinder barrel 421, and the piston moves under the pressure of the hydraulic oil and extends out of the cylinder barrel 421. As a result, the piston rod 422 extends, which can raise the height of the loading platform 3. When it is necessary to control the shortening of the support cylinder 42, the hydraulic oil in the cylinder 421 flows back to the oil storage chamber 411 through the oil passage 412. At this time, the piston rod 422 can retract back into the cylinder 421, thereby lowering the height of the loading platform 3. Thus, by having hydraulic oil enter different cylinders 421 through different oil passages 412, the extension or retraction of different support cylinders 42 can be controlled. Therefore, when the platform 2 and the vehicle body 1 are in an inclined state, the extension and retraction of multiple support cylinders 42 can raise or lower different positions of the loading platform 3, keeping the loading platform 3 horizontal, so that the power module can be kept horizontal during the process of lifting the power module onto the loading platform 3.

[0036] Because the ground slope causes the hydraulic oil to have different pressure distributions in the oil circuit 412 under the action of gravity, the hydraulic oil at the lower position will have higher pressure due to gravity, while the hydraulic oil at the higher position will have lower pressure due to downward flow. Therefore, when the vehicle body 1 needs to move to the slope to disassemble and assemble the power module on the uneven ground, the support platform 2 and the integrated plate 5 will both tilt along with the vehicle body 1. The hydraulic oil in the support cylinder 42 at the higher position in the integrated plate 5 will flow out of the cylinder 421 and into the oil storage chamber 411, and then flow into the oil circuit 412 connected to the support cylinder 42 at the lower position to supply oil to the support cylinder 42 at the lower position. In this way, the hydraulic oil in the cylinder 421 of the support cylinder 42 located at a higher elevation flows out, causing its piston rod 422 to retract downwards. The hydraulic oil then flows into the cylinder 421 of the support cylinder 42 located at a lower elevation, causing its piston rod 422 to extend under pressure. This achieves the adjustment of the loading platform 3's posture. Because the height of each support cylinder 42 is different when the integrated plate 5 tilts, the amount of hydraulic oil entering the cylinder 421 at different heights and the pressure it experiences are also different. This allows for the adjustment of the extension and retraction of the support cylinders 42 at different heights, enabling the loading platform 3 to be adjusted to a horizontal state.

[0037] In the embodiments provided in this disclosure, reference is made to Figure 3 As shown, the power module auxiliary disassembly and assembly device also includes a sealing component for sealing the oil reservoir 411. This ensures that the hydraulic oil in the reservoir 411 remains in a sealed environment, helping to maintain hydraulic oil pressure, thereby improving the efficiency of the hydraulic system and reducing power loss. Simultaneously, it prevents hydraulic oil leakage, ensuring stable oil volume and avoiding a decrease in support performance due to oil loss. Furthermore, it prevents dust, moisture, and other contaminants from entering the hydraulic oil, keeping the oil clean, extending its service life, and reducing the frequency of maintenance and replacement of the hydraulic system.

[0038] In the embodiments provided in this disclosure, reference is made to Figure 3 As shown, the integrated plate 5 has an adjustment hole 51 communicating with the oil storage chamber 411. The sealing assembly includes an adjustment rod 61 and a stop plug 62. The adjustment rod 61 is located in the adjustment hole 51, and the stop plug 62 is slidably disposed in the oil storage chamber 411. The adjustment rod 61 is used to push the stop plug 62 to slide and block the oil storage chamber 411. In this way, the amount of hydraulic oil in the oil storage chamber 411, the oil passage communicating with the oil storage chamber 411, and the support cylinder 42 can be kept constant. When the hydraulic oil flows between multiple oil passages 412, the extension and retraction of the support cylinder 42 communicating with different oil passages 412 can be adjusted. When the loading platform 3 is adjusted to a horizontal state, the adjustment rod 61 can push the stop plug 62 to block the oil storage chamber 411 to prevent hydraulic oil from overflowing from the oil storage chamber 411. Therefore, once the loading platform 3 is adjusted to a horizontal state, it can remain horizontal as long as the ground conditions (i.e., the degree of ground inclination) remain unchanged. Furthermore, through this design, the attitude of the loading platform 3 can be adaptively adjusted according to the ground conditions, making the adjustment flexible and convenient.

[0039] In the embodiments provided in this disclosure, for ease of operation of the stop plug 62, refer to Figure 3 As shown, the adjusting rod 61 may include a screw 611 and a sliding rod 612. The sliding rod 612 is slidably disposed in the adjusting hole 51, and the stop plug 62 is fixedly connected to one end of the sliding rod 612. The other end of the sliding rod 612 is provided with a threaded hole, and the screw 611 is threadedly connected to the threaded hole. In this way, when it is necessary to adjust the sliding of the stop plug 62 in the oil reservoir 411, the sliding rod 612 can be pushed by rotating the adjusting rod 61, thereby causing the stop plug 62 to slide and thus sealing the oil reservoir 411.

[0040] In the embodiments provided in this disclosure, reference is made to Figure 3As shown, a limiting member 52 can be provided within the adjusting hole 51. The limiting member 52 forms a limiting hole, through which the screw 611 passes and extends into the threaded hole, where it is threadedly connected. To fix the position of the limiting member 52, the adjusting hole 51 is formed as a stepped hole, with the relative stepped surfaces of the stepped hole fixing the position of the limiting member 52. With this configuration, the limiting member 52 can restrict the movement range of the slide rod 612, ensuring that the slide rod 612 moves within a preset range, while the screw 611 can rotate relative to the limiting member 52.

[0041] In the embodiments provided in this disclosure, reference is made to Figure 1 and Figure 2 As shown, a limiting frame 31 can be provided on the side of the loading platform 3 away from the bearing platform 2. The limiting frame 31 forms a limiting space to limit the power module. In this way, the limiting frame 31 can limit the power module around its perimeter, preventing the power module from shifting and sliding off the loading platform 3, thus preventing damage from impacts, and protecting the power module on the loading platform 3.

[0042] In the embodiments provided in this disclosure, reference is made to Figure 1 and Figure 2 As shown, the integrated plate 5 can be constructed in a circular shape, and the integrated plate 5 has a toothed structure arranged circumferentially. The power module auxiliary disassembly and assembly device also includes a worm gear 7, which is connected to the toothed structure for transmission. In this way, by rotating the worm gear 7, the integrated plate 5 can be rotated to adjust the angle of the limiting frame 31, so that the position of the limiting frame 31 corresponds to the position of the power module, so that the power module can be moved into the limiting frame 31, reducing the possibility of collisions when adjusting the position of the power module.

[0043] In the embodiments provided in this disclosure, reference is made to Figure 1 and Figure 2 As shown, the power module auxiliary disassembly and assembly device may also include an operating handwheel 8, which is sleeved on and fixedly connected to the worm 7. This allows the worm 7 to rotate by cranking the operating handwheel 8, achieving a larger torque output with a smaller torque, saving the force required for the operator to rotate the worm 7. Furthermore, the operating handwheel 8 enables stable rotation of the worm 7, reducing operational errors caused by manual operation.

[0044] In the embodiments provided in this disclosure, reference is made to Figure 1 and Figure 2 As shown, the power module auxiliary disassembly and assembly device may include a lifting assembly 9, and the support platform 2 is vertically and flexibly mounted on the vehicle body 1 via the lifting assembly 9. In this way, the height of the support platform 2 can be adjusted by the lifting assembly 9 so that the height of the support platform 2 is adapted to the height of the power module to be disassembled, reducing the movement of the power module in terms of height.

[0045] The lifting assembly 9 can be configured as a scissor lift mechanism to realize the vertical lifting movement of the support platform 2. In other embodiments of this disclosure, the lifting assembly 9 can also be configured as a hydraulic drive assembly such as a support cylinder 42 to drive the vertical lifting movement of the support platform 2. This disclosure does not impose specific limitations on this.

[0046] Below, for reference Figures 1 to 3 As shown, this disclosure will provide a detailed description of the specific usage process of the power module auxiliary disassembly and assembly device in conjunction with the above-described specific embodiments. When it is necessary to disassemble or assemble a power module, if the power module to be disassembled or assembled is on an inclined surface, the vehicle body 1 of the disassembly and assembly vehicle is moved to a position close to the power module. The vehicle body 1 will tilt, and the height of the support platform 2 is adjusted by the lifting mechanism so that the position of the loading platform 3 corresponds to the position of the power module. At this time, since the vehicle body 1 is on an inclined surface, the hydraulic oil in the support cylinder 42 located at the higher elevation in the integrated plate 5 will flow out of the cylinder 421 and, after entering the oil storage chamber 411, flow into the oil passage 412 connected to the support cylinder 42 located at the lower elevation, to supply oil to the support cylinder 42 located at the lower elevation. In this way, the hydraulic oil in the cylinder 421 of the support cylinder 42 at the higher elevation flows out, and the piston rod 422 retracts downward, causing the loading platform 3 at the higher elevation to move down. The hydraulic oil flows into the cylinder 421 of the support cylinder 42 at the lower elevation, causing the piston rod 422 of the support cylinder 42 at the lower elevation to extend under pressure, thereby pushing the support platform 2 at the lower elevation to move upward. Since the height of each support cylinder 42 is different when the integrated plate 5 is tilted, the amount of hydraulic oil entering the cylinder 421 and the pressure it experiences are also different, thus enabling the adjustment of the extension and retraction of the support cylinders 42 at different heights. Because the hydraulic oil volume in the oil reservoir 411, the oil passages connected to the oil reservoir 411, and the support cylinder 42 can remain constant, when the hydraulic oil flows between multiple oil passages 412 to adjust the extension and retraction of the support cylinder 42 connected to different oil passages 412, when the loading platform 3 is adjusted to a horizontal state, the adjusting rod 61 can push the stop plug 62 to block the oil reservoir 411, preventing hydraulic oil from overflowing from the oil reservoir 411. Therefore, when the loading platform 3 is adjusted to a horizontal state, under the condition that the ground conditions (i.e., the ground inclination) remain unchanged, the loading platform 3 can always remain horizontal, and the posture of the loading platform 3 can be adaptively adjusted according to the ground conditions, making the adjustment flexible and convenient. Rotating the operating handwheel 8 rotates the worm gear 7, causing the integrated plate 5, which is connected to the worm gear 7, to rotate. This allows for adjustment of the rotation position of the support platform 2, enabling the angle of the limiting frame 31 to correspond to the angle of the power module. This allows the power module to be directly placed in the limiting frame 31 when it is moved horizontally to the loading platform 3, facilitating its disassembly.
