Description

Technical Field

[0001] This invention relates to the field of transformer transportation technology, specifically to equipment and methods for simulating long-term bumpy transportation of transformers. Background Technology

[0002] If a transformer is damaged by vibration during transportation, the internal core windings may shift, connectors may deform, and oil leaks may even occur. Some of these damages are relatively obvious and can be repaired promptly upon arrival at the station. However, some damages are less noticeable or more extensive, posing significant risks to the transformer's operation. Ensuring the safe transportation of transformers is crucial for their normal and safe use.

[0003] Before leaving the factory, it is essential to conduct random checks on the anti-bump performance of transformers in each batch. During the transportation of transformers by vehicle, the transformers are fixed on the vehicle body, and the road bumps experienced by the vehicle body are random. When the tires pass through large bumps, the tires may even lift off the ground. Existing bump simulation devices often connect directly to the platform on which the transformer is placed via a swaying mechanism. The swaying generated by the swaying mechanism acts directly on the transformer, which cannot provide a random vibration distribution or sufficient degrees of freedom (such as the free fall of a tire after it leaves the ground). The acceleration change of the transformer is completely consistent with the swaying mechanism, and the realism of the simulated bumps differs greatly from that of actual transportation.

[0004] Therefore, in response to the above problems, equipment and methods for simulating long-term bumpy transportation of transformers are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide equipment and methods for simulating long-term bumpy transportation of transformers, which can greatly improve the realism of simulating bumpy transportation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for simulating long-term bumpy transportation of a transformer, including a simulated vehicle platform, a support frame and a fixed plate, with sleepers fixedly connected to the inner top of the simulated vehicle platform, the transformer sitting on the sleepers and fixed to the simulated vehicle platform by connectors, and two sliding mechanisms provided at the bottom of the simulated vehicle platform; A telescopic rod is rotatably connected to the upper side of the fixed plate via a hinge, and the other end of the telescopic rod is rotatably connected to the simulated vehicle plate via a hinge. The top of the support frame is rotatably connected to a first rotating roller and a second rotating roller via a rotating shaft. The cross-sections of the first rotating roller and the second rotating roller have transitional protrusions. The first rotating roller and the second rotating roller are respectively located on the lower side of the two sliding mechanisms. When the first rotating roller and the second rotating roller rotate, they cause a bumping effect on the simulated vehicle platform. When the first and second rotating rollers rotate, there is a height difference between the contact points of the first and second rotating rollers and the two sliding mechanisms. This height difference changes randomly due to the asynchronous rotation, thus simulating random bumps. The simulated vehicle platform has a high degree of freedom. When the rotation speed of the first and second rotating rollers increases, the simulated vehicle platform can even detach from the support and lift up, thus achieving a high degree of freedom simulation. Compared with the prior art, where the acceleration change of the transformer is completely consistent with the shaking mechanism, the simulation device of the present invention has a higher degree of matching with the real environment in simulating bumps, and its performance test after bumps is more referential. The sliding mechanism exists to compensate for the rotation of the first and second rotating rollers. Since the contact connection damping force cannot be completely eliminated, complete compensation cannot be achieved, and there will always be a driving force. The first and second rotating rollers rotate in opposite directions to prevent the first and second rotating rollers from acting in the same direction, so that the rotation driving forces of the first and second rotating rollers can be canceled out as much as possible, and to prevent the simulated vehicle board from deviating excessively in one direction. However, because the rotation speeds of the first and second rotating rollers are inconsistent, there will always be a deviation in the driving force of the first and second rotating rollers. This deviation will still cause the simulated vehicle board to deviate. Therefore, the present invention provides a damping adjustment mechanism between the two sliding mechanisms. By changing the relative damping value between the two sliding mechanisms, the sliding mechanism can be made longer, so that the simulated vehicle board has sufficient forward and backward movement, controls the forward and backward movement of the simulated vehicle board, and makes the simulated vehicle board adjust to the initial installation position in time. In the initial position, both the first and second rotating rollers are in the middle position at the bottom of the sliding mechanism. There is a slight speed difference between the first and second rotating rollers, which creates randomness in the turbulence.

[0007] Preferably, as a device for simulating long-term bumpy transportation of transformers according to the present invention, the outer sides of the first rotating roller and the second rotating roller are covered with a rubber layer, which is used to prevent slippage between the rotating roller and the sliding mechanism. As a preferred embodiment of the device for simulating long-term bumpy transportation of a transformer according to the present invention, a first motor and a commutator are fixedly connected to the top right side of the support frame. The output end of the first motor is fixedly connected to the shaft of the second rotating roller. A driving wheel is rotatably connected to the shaft of the second rotating roller. A driven wheel is fixedly connected to the outer side of the first rotating roller. The driving wheel and the driven wheel are driven by a transmission belt. There is a slight diameter difference between the driving wheel and the driven wheel, which causes a speed difference between the first rotating roller and the second rotating roller.

[0008] The present invention realizes the reversing of the first rotating roller and the second rotating roller through a reversing box. Since the first rotating roller and the second rotating roller are driven by a driven wheel and a driving wheel respectively, the present invention generates a speed difference between the first rotating roller and the second rotating roller by means of a slight diameter difference between the driving wheel and the driven wheel. Preferably, in the device for simulating long-term bumpy transportation of a transformer according to the present invention, a third bevel gear is fixedly connected to one side of the drive wheel, a second bevel gear is rotatably connected to the inner side of the commutation box, and a first bevel gear is fixedly connected to the shaft of the second rotating roller. Both the third bevel gear and the first bevel gear mesh with the second bevel gear to achieve steering. Multiple second bevel gears can be arranged in a ring around the outer side of the shaft to increase stability. When the first motor rotates, the first bevel gear rotates counterclockwise, the second bevel gear rotates clockwise, and the third bevel gear also rotates clockwise. The third bevel gear drives the drive wheel to rotate clockwise, thereby achieving steering. At this time, the first rotating roller rotates clockwise, and the second rotating roller rotates counterclockwise. As a preferred device for simulating long-term bumpy transportation of transformers in this invention, the telescopic rod is used to limit the movement and prevent the simulated vehicle platform from shifting excessively. The telescopic rod includes an outer cylinder, a piston is slidably connected to the inner side of the outer cylinder, and an inner rod is fixedly connected to the other end of the piston. A potentiometer is embedded in the inner wall of the outer cylinder, and the piston slides on the potentiometer to obtain the specific position of the piston inside the outer cylinder. The inner rod is rotatably connected to the simulated vehicle platform through a hinge, and the outer cylinder is rotatably connected to the fixed plate through a hinge.

[0009] As the bumps continue to occur, when the piston position deviates excessively, the simulated vehicle plate is slowly returned to its initial position by adjusting the relative damping value between the two sliding mechanisms. As a preferred device for simulating long-term bumpy transportation of a transformer according to the present invention, the sliding mechanism includes a mounting plate fixed to the simulated vehicle platform. A side plate is fixedly connected to the bottom end of the mounting plate. Two rotating columns are rotatably connected between the front and rear side plates. A sliding belt is fitted between the two rotating columns. A sprocket connection can also be used between the sliding belt and the rotating columns to prevent slippage. The lower side of the sliding belt is supported by a stop plate fixedly connected between the front and rear side plates. Lubricating oil exists between the stop plate and the inner side of the sliding belt to reduce sliding wear. The sliding mechanism can refer to a conveyor belt or treadmill, which is existing technology and will not be elaborated further here. As a preferred device for simulating long-term bumpy transportation of transformers according to the present invention, the damping adjustment mechanism includes an oil rod and a sliding cavity inside the side plate. A sliding block and a pressure block are slidably connected inside the sliding cavity. A first spring is fixedly connected between the sliding block and the pressure block. The two ends of the oil rod are respectively connected to the ends of the sliding cavities in the left and right side plates that are away from the pressure blocks. The sliding damping force of the sliding mechanism is adjusted by adjusting the amount of oil in the sliding cavity.

[0010] As a preferred device for simulating long-term bumpy transportation of a transformer according to the present invention, when one of the sliding chambers is filled with oil, the squeezing force of the side pressure block on the rotating column increases, and the sliding damping force of the side sliding mechanism increases. When the sliding chamber in the other side plate is de-oiled, the squeezing force of the other side pressure block on the rotating column decreases, and the sliding damping force of the side sliding mechanism decreases, thereby realizing the adjustment of the driving force on the left and right sides, which is used to load the acceleration of the simulated vehicle plate in the forward direction, and realize the simulation of forward and backward movement through the change of acceleration.

[0011] As a preferred embodiment of the device for simulating long-term bumpy transportation of a transformer according to the present invention, an oil tank is connected to the middle position of the oil rod, an adjusting block is slidably connected to the inner side of the oil tank, hydraulic oil is filled inside the oil rod and the oil tank, a return spring is fixedly connected between the adjusting block and the inner side of the oil tank, a second motor is fixedly connected to the outer side of the oil tank, a space exists inside the adjusting block, the output end of the second motor extends into the inner side of the adjusting block and is fixedly connected to a cam, when the second motor drives the cam to rotate, the adjusting block can move left and right, and the damping of the sliding mechanism on both sides is synchronously adjusted by the left and right movement of the adjusting block.

[0012] A method for simulating long-term bumpy transportation of transformers, comprising the following steps: Step 1: Installation. Place the transformer on the sleepers and then fix it to the simulator board using connectors, or fix it directly to the sleepers. Step 2: Bump simulation. The first motor rotates, and the second rotating roller rotates. After the first rotating roller is turned by the reversing box, it rotates in the opposite direction. Because there is a slight diameter difference between the driving wheel and the driven wheel, there is a height difference between the contact points of the first and second rotating rollers with the two sliding mechanisms. This height difference is in random change due to the asynchronous rotation, thus realizing random bump simulation. The simulated vehicle platform has a high degree of freedom. When the speed of the first motor increases, the simulated vehicle platform can even detach from the support and lift up, thus realizing high degree of freedom simulation. Step 3: Adjust the amount of oil in the sliding cavity to adjust the sliding damping force of the sliding mechanism, thereby adjusting the driving force on both sides to load the acceleration of the simulated vehicle plate in the forward direction.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. The equipment for simulating long-term bumpy transportation of transformers has transitional protrusions in the cross-sections of the first and second rotating rollers. The first and second rotating rollers are respectively set on the lower side of two sliding mechanisms. When the first and second rotating rollers rotate, there is a height difference between the contact points of the first and second rotating rollers and the two sliding mechanisms. This height difference is in random change due to the asynchronous rotation, thereby realizing random bumpy simulation.

[0014] 2. This device, which simulates the long-term bumpy transportation of a transformer, has a high degree of freedom in simulating the vehicle platform. When the rotation speed of the first and second rotating rollers increases, the simulated vehicle platform can even detach from the support and lift up, thus achieving a high degree of freedom in simulation. Compared with the prior art, where the acceleration change of the transformer is completely consistent with the shaking mechanism, the simulation device of this invention has a higher degree of matching with the real environment in simulating bumps, and its performance test after bumps is more referential.

[0015] 3. The sliding mechanism in this equipment, which simulates the long-term bumpy transportation of a transformer, is designed to compensate for the rotation of the first and second rotating rollers. Since the contact connection damping force cannot be completely eliminated, complete compensation cannot be achieved, and there will always be a driving force. The opposite rotation directions of the first and second rotating rollers are to prevent the action directions of the first and second rotating rollers from being the same, so that the rotation driving forces of the first and second rotating rollers can be canceled out as much as possible, and to prevent the simulated vehicle board from deviating excessively in one direction.

[0016] 4. This device simulates a transformer that is transported under constant bumps. However, because the rotation speeds of the first and second rotating rollers are inconsistent, there will always be a deviation in the driving force of the first and second rotating rollers. This deviation will still cause the simulated vehicle to deviate. Therefore, this invention provides a damping adjustment mechanism between the two sliding mechanisms. By changing the relative damping value between the two sliding mechanisms, the sliding mechanism can be made longer, so that the simulated vehicle has sufficient forward and backward movement, controls the forward and backward movement of the simulated vehicle, and makes the simulated vehicle adjust to the initial installation position in time. In the initial position, both the first and second rotating rollers are in the middle position at the bottom of the sliding mechanism. 5. This device for simulating long-term bumpy transportation of transformers, the present invention realizes the reversing of the first rotating roller and the second rotating roller through the reversing box. Since the first rotating roller and the second rotating roller are driven by the driven wheel and the driving wheel respectively, the present invention generates a speed difference between the first rotating roller and the second rotating roller by the slight diameter difference between the driving wheel and the driven wheel. 6. This equipment, which simulates the long-term bumpy transportation of a transformer, will allow the simulated vehicle to slowly return to its initial position when the piston position deviates excessively due to continuous bumps. The sliding damping force of the sliding mechanism is adjusted by adjusting the relative damping value between the two sliding mechanisms. This adjustment of the driving force on both sides is used to load the acceleration of the simulated vehicle in the forward direction. The forward and backward movement is simulated by the change in acceleration. When the second motor drives the cam to rotate, the adjusting block can move left and right. The left and right movement of the adjusting block realizes the synchronous adaptive adjustment of the damping of the sliding mechanisms on both sides. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1, please refer to Figures 1-6 and Figure 10The present invention provides a technical solution: The equipment and method for simulating long-term bumpy transportation of a transformer includes a simulated vehicle platform 3, a support frame 1, and a fixed plate 7. A sleeper 4 is fixedly connected to the inner top of the simulated vehicle platform 3. The transformer 5 sits on the sleeper 4 and is fixed to the simulated vehicle platform 3 by a connector. Two sliding mechanisms are provided at the bottom of the simulated vehicle platform 3. The upper side of the fixed plate 7 is rotatably connected to the telescopic rod 8 via a hinge, and the other end of the telescopic rod 8 is rotatably connected to the simulated vehicle plate 3 via a hinge. The top of the support frame 1 is rotatably connected to the first rotating roller 12 and the second rotating roller 13 via a rotating shaft. The cross sections of the first rotating roller 12 and the second rotating roller 13 have transitional protrusions. The first rotating roller 12 and the second rotating roller 13 are respectively located on the lower side of the two sliding mechanisms. When the first rotating roller 12 and the second rotating roller 13 rotate, they cause a bumping effect on the simulated vehicle platform 3. When the first rotating roller 12 and the second rotating roller 13 rotate, there is a height difference between the contact points of the first rotating roller 12 and the second rotating roller 13 with the two sliding mechanisms, and this height difference is in random change due to the asynchronous rotation, thereby realizing random bump simulation. Moreover, the simulated vehicle platform 3 has a high degree of freedom. When the rotation speed of the first rotating roller 12 and the second rotating roller 13 increases, the simulated vehicle platform 3 can even detach from the support and lift up, thereby realizing a high degree of freedom simulation. Compared with the prior art, where the acceleration change of the transformer is completely consistent with the shaking mechanism, the simulation device of the present invention has a higher degree of matching with the real environment in simulating bumps, and its performance test after bumps is more referential. The sliding mechanism exists to compensate for the rotation of the first rotating roller 12 and the second rotating roller 13. Because the contact connection damping force cannot be completely eliminated, complete compensation cannot be achieved, and there will always be a driving force. The first rotating roller 12 and the second rotating roller 13 rotate in opposite directions to prevent the first rotating roller 12 and the second rotating roller 13 from acting in the same direction, so that the rotation driving forces of the first rotating roller 12 and the second rotating roller 13 are canceled out as much as possible, and to prevent the simulated vehicle plate 3 from deviating excessively in one direction. However, because the rotation speeds of the first rotating roller 12 and the second rotating roller 13 are inconsistent, there will always be a deviation in the driving force of the first rotating roller 12 and the second rotating roller 13. This deviation will still cause the simulated vehicle plate 3 to deviate. Therefore, the present invention provides a damping adjustment mechanism between the two sliding mechanisms. By changing the relative damping value between the two sliding mechanisms, the sliding mechanism can be made longer, so that the simulated vehicle plate 3 has sufficient forward and backward movement, controls the forward and backward movement of the simulated vehicle plate 3, and makes the simulated vehicle plate 3 adjust to the initial installation position in time. In the initial position, the first rotating roller 12 and the second rotating roller 13 are both in the middle position at the bottom of the sliding mechanism. There is a slight speed difference between the first rotating roller 12 and the second rotating roller 13, which achieves randomness in the bumping by means of the speed difference.

[0021] Specifically, the outer sides of the first rotating roller 12 and the second rotating roller 13 are covered with a rubber layer, which is used to prevent slippage between the rotating rollers and the sliding mechanism; Specifically, a first motor 2 and a reversing box 15 are fixedly connected to the top right side of the support frame 1. The output end of the first motor 2 is fixedly connected to the shaft of the second rotating roller 13. A drive wheel 14 is rotatably connected to the shaft of the second rotating roller 13. A driven wheel 11 is fixedly connected to the outer side of the first rotating roller 12. The drive wheel 14 and the driven wheel 11 are driven by a transmission belt 10. There is a slight diameter difference between the drive wheel 14 and the driven wheel 11, which causes a speed difference between the first rotating roller 12 and the second rotating roller 13.

[0022] The present invention realizes the reversing of the first rotating roller 12 and the second rotating roller 13 through the reversing box 15. Since the first rotating roller 12 and the second rotating roller 13 are driven by the driven wheel 11 and the driving wheel 14 respectively, the present invention generates a speed difference between the first rotating roller 12 and the second rotating roller 13 by the slight diameter difference between the driving wheel 14 and the driven wheel 11. Specifically, a third bevel gear 153 is fixedly connected to one side of the drive wheel 14, a second bevel gear 152 is rotatably connected to the inner side of the reversing gearbox 15, and a first bevel gear 151 is fixedly connected to the shaft of the second rotating roller 13. Both the third bevel gear 153 and the first bevel gear 151 mesh with the second bevel gear 152 to achieve steering. Multiple second bevel gears 152 can be arranged in a ring around the outer side of the shaft to increase stability. When the first motor 2 rotates, the first bevel gear 151 rotates counterclockwise, the second bevel gear 152 rotates clockwise, and the third bevel gear 153 also rotates clockwise. The third bevel gear 153 drives the drive wheel 14 to rotate clockwise, thereby achieving steering. At this time, the first rotating roller 12 rotates clockwise, and the second rotating roller 13 rotates counterclockwise. Specifically, the telescopic rod 8 is used to limit the movement and prevent the simulated vehicle plate 3 from shifting excessively. The telescopic rod 8 includes an outer cylinder 81, a piston 82 is slidably connected to the inner side of the outer cylinder 81, and an inner rod 83 is fixedly connected to the other end of the piston 82. A potentiometer 84 is embedded in the inner wall of the outer cylinder 81. The piston 82 slides on the potentiometer 84 to obtain the specific position of the piston 82 inside the outer cylinder 81. The inner rod 83 is rotatably connected to the simulated vehicle plate 3 through a hinge, and the outer cylinder 81 is rotatably connected to the fixed plate 7 through a hinge.

[0023] As the bumps continue to occur, when the position of piston 82 deviates excessively, the simulated vehicle plate 3 is slowly returned to its initial position by adjusting the relative damping value between the two sliding mechanisms. Specifically, the sliding mechanism includes a mounting plate 6 fixed to the simulated vehicle platform 3. A side plate 61 is fixedly connected to the bottom of the mounting plate 6. Two rotating posts 62 are rotatably connected between the front and rear side plates 61. A sliding belt 63 is fitted between the two rotating posts 62. The sliding belt 63 can also be connected to the rotating posts 62 by a sprocket to prevent slippage. The lower side of the sliding belt 63 is supported by a stop plate 64 fixedly connected between the front and rear side plates 61. Lubricating oil exists between the stop plate 64 and the inner side of the sliding belt 63 to reduce sliding wear. The sliding mechanism can be based on a conveyor belt or treadmill, which is existing technology and will not be elaborated upon here.

[0024] Example 2 is a further improvement upon Example 1. Please refer to Example 1. Figures 1-10 The damping adjustment mechanism includes an oil rod 9 and a sliding cavity 92 inside the side plate 61. A sliding block 93 and a pressure block 95 are slidably connected inside the sliding cavity 92. A first spring 94 is fixedly connected between the sliding block 93 and the pressure block 95. The two ends of the oil rod 9 are respectively connected to the ends of the sliding cavities 92 in the left and right side plates 61 that are away from the pressure block 95. The sliding damping force of the sliding mechanism is adjusted by adjusting the amount of oil in the sliding cavity 92.

[0025] As a preferred device for simulating long-term bumpy transportation of a transformer according to the present invention, when one of the sliding chambers 92 is filled with oil, the squeezing force of the side pressure block 95 on the rotating column 62 increases, and the sliding damping force of the side sliding mechanism increases. When the sliding chamber 92 in the other side plate 61 is de-oiled, the squeezing force of the other side pressure block 95 on the rotating column 62 decreases, and the sliding damping force of the side sliding mechanism decreases, thereby realizing the adjustment of the driving force on the left and right sides, which is used to load the acceleration of the simulated vehicle plate 3 in the forward direction, and realize the simulation of forward and backward movement through the change of acceleration.

[0026] Specifically, the middle position of the hydraulic rod 9 is connected to the oil tank 91, and the inner side of the oil tank 91 is slidably connected to the adjusting block 97. The hydraulic rod 9 and the inner side of the oil tank 91 are filled with hydraulic oil. A return spring 99 is fixedly connected between the adjusting block 97 and the inner side of the oil tank 91. A second motor 96 is fixedly connected to the outer side of the oil tank 91. There is space inside the adjusting block 97. The output end of the second motor 96 extends into the inner side of the adjusting block 97 and is fixedly connected to the cam 98. When the second motor 96 drives the cam 98 to rotate, the adjusting block 97 can move left and right. The left and right movement of the adjusting block 97 realizes the synchronous adaptive adjustment of the damping of the sliding mechanism on both sides.

[0027] This invention also discloses a method for simulating long-term bumpy transportation of a transformer, the steps of which are: Step 1: Installation. Place the transformer 5 on the sleeper 4 and then fix it to the simulation vehicle board 3 using the connectors, or fix it directly to the sleeper 4. Step 2: Bump simulation. The first motor 2 rotates, and the second rotating roller 13 rotates. The first rotating roller 12 rotates in the opposite direction after being turned by the reversing box 15. Because there is a slight diameter difference between the driving wheel 14 and the driven wheel 11, there is a height difference between the contact points of the first rotating roller 12 and the second rotating roller 13 with the two sliding mechanisms. This height difference is in random change due to the asynchronous rotation, thus realizing random bump simulation. The simulated vehicle platform 3 has a high degree of freedom. When the speed of the first motor 2 increases, the simulated vehicle platform 3 can even detach from the support and lift up, thus realizing high degree of freedom simulation. Step 3: Adjust the amount of oil in the sliding cavity 92 to adjust the sliding damping force of the sliding mechanism, thereby adjusting the driving force on the left and right sides to load the acceleration of the simulated vehicle plate 3 in the forward direction.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

10. A method for simulating long-term bumpy transportation of a transformer, using the equipment for simulating long-term bumpy transportation of a transformer as described in claim 9, characterized in that, The steps are as follows: Step 1: Installation. Place the transformer (5) on the sleeper (4) and then fix it to the simulation vehicle board (3) with the connector, or fix it directly to the sleeper (4); Step 2: Bump simulation. The first motor (2) rotates, the second rotating roller (13) rotates, the first rotating roller (12) rotates in the opposite direction after being turned by the reversing box (15), and because there is a slight diameter difference between the driving wheel (14) and the driven wheel (11), there is a height difference between the contact points of the first rotating roller (12) and the second rotating roller (13) with the two sliding mechanisms respectively, and this height difference is in random change due to the asynchronous rotation, thus realizing random bump simulation, and the simulated vehicle platform (3) has a high degree of freedom. When the speed of the first motor (2) increases, the simulated vehicle platform (3) can even detach from the support and lift up, thus realizing high degree of freedom simulation; Step 3: Adjust the amount of oil in the sliding cavity (92) to adjust the sliding damping force of the sliding mechanism, thereby adjusting the driving force on the left and right sides to load the acceleration of the simulated vehicle plate (3) in the forward direction.
