[0003] In the related art, the transformer is often moved by using a pier, a jack and a track. When operating, the pier is first moved to a special jacking point position at the four corners of the transformer, and then the jack is used in cooperation to jack up the transformer. Then, the track is moved to the lower side of the transformer, and the transformer is connected to the sliding support structure arranged on the track. In this way, the sliding support structure is slidably connected on the track, and the transformer is supported on the track by the sliding support structure and can move along the track with the sliding support structure under the action of an external force, so that the transformer can be transferred to the relevant maintenance position.

[0004] In actual operation, the transformer is heavy, there is a large frictional resistance between the sliding support structure and the steel rail, and the contact part of the sliding support structure and the track is prone to wear. As the movement progresses, the wear is aggravated, the contact surface becomes rougher, the movement difficulty is increased, the movement of the transformer is blocked, and even the contact surface may need to be polished again before the movement can be resumed. In this way, the movement efficiency of the transformer is difficult to improve. UTILITY MODEL CONTENT

[0036] Nuclear power plants require regular maintenance. When maintaining transformers, a mobile device is needed to move the transformers to the maintenance location.

[0037] In the related art, the transformer is moved by means of supporting piers, jacks and rails. When operating, the supporting piers are first moved to the positions of the jacks specially arranged at the four corners of the transformer, then the transformer is lifted by the jacks, the rails are moved to the lower side of the transformer, and the transformer is connected to the sliding support structure arranged on the rails. In this way, the sliding support structure is connected to the rails, the transformer is supported on the rails by the sliding support structure, and can move along the rails with the sliding support structure under the action of external force, so that the transformer can be transferred to the relevant maintenance position.

[0038] In actual operation, the transformer is heavy, there is large frictional resistance between the sliding support structure and the rails, the contact part of the sliding support structure with the rails is prone to wear, and the wear is aggravated with the movement, the contact surface becomes rougher, the movement difficulty is increased, the movement of the transformer is blocked, and the sliding support structure and the rails may even be locked and cannot be moved any more. Further increase in the pushing force or even re-grinding of the contact surface is required before the movement can be continued. In this way, the movement of the transformer is difficult, the movement efficiency is difficult to improve, and the overall efficiency of the maintenance is seriously affected.

[0039] Based on this, the embodiment of the present application provides a bearing moving device to solve the above problems.

[0040] Please refer to Figures 1 to 6 The bearing moving device provided by the embodiment of the present application is suitable for, but not limited to, moving large equipment and devices including transformers when detecting the equipment of a nuclear power plant.

[0041] In the embodiment of the present application, as Figures 1 to 3 shown, the bearing moving device comprises a support assembly 10 and a sliding assembly 20. The support assembly 10 comprises a rail 11 having a support part 111, and the support part 111 extends along the length direction of the rail 11. The sliding assembly 20 comprises a bearing seat 21 and a connecting seat 22 connected to the bearing seat 21. The connecting seat 22 is slidably installed on the support part 111, and the bearing seat 21 is used for bearing the external device to be moved. The connecting seat 22 is provided with a sliding groove 221 for adapting and clamping the support part 111. The sliding groove 221 is provided with a partition piece 222 towards the bottom wall of the support part 111. The partition piece 222 is clamped between the connecting seat 22 and the support part 111, and the wear resistance of the partition piece 222 is greater than that of the surface of the connecting seat 22 opposite to the support part 111.

[0042] In the embodiment, the carrying and moving device comprises a supporting assembly 10 for supporting a device to be moved, the device to be moved is lifted by the supporting assembly 10 without being in contact with a mounting surface such as the ground, and no frictional resistance exists between the device to be moved and the mounting surface such as the ground during the movement. The supporting assembly 10 comprises a track 11 having a certain extension, and the track 11 further comprises a supporting portion 111 for supporting the device to be moved, so that the device to be moved can move along the track 11.

[0043] In the embodiment, the carrying and moving device further comprises a sliding assembly 20 for connecting the device to be moved to the track 11, and the sliding assembly 20 can move along the length direction of the track 11, thereby driving the device to be moved to move along the length direction of the track 11 synchronously. The sliding assembly 20 comprises a carrying seat 21 and a connecting seat 22, the connecting seat 22 is connected to the supporting portion 111 of the track 11 through a sliding groove 221, and the carrying seat 21 is connected to the connecting seat 22 and carries the device to be moved.

[0044] In the embodiment, the sliding groove 221 is provided with a partition piece 222 facing the bottom wall of the supporting portion 111, the partition piece 222 is clamped between the connecting seat 22 and the supporting portion 111, and the wear resistance of the partition piece 222 is greater than that of the surface of the connecting seat 22 facing the supporting portion 111. It can be understood that the wear resistance refers to the performance of the material resisting wear, and the wear is the process of the working surface material of an object being continuously worn in relative motion. For example, when a car tire moves on the road, the surface of the tire is in continuous contact and friction with the ground, which will gradually wear; the mechanical structures in contact with each other will also wear during mutual movement, for example, when the connecting seat 22 is in direct contact with the supporting portion 111 of the track 11, the bottom wall of the sliding groove 221 of the connecting seat 22 is in contact with the supporting portion 111, and both will be worn during the movement of the connecting seat 22; for another example, when the connecting seat 22 is in direct contact with the supporting portion 111 through the partition piece 222, the partition piece 222 is in contact with the supporting portion 111, and both will also be worn during the movement of the connecting seat 22. The surface of the connecting seat 22 facing the supporting portion 111 at least includes the surface of the bottom wall of the groove bottom of the connecting seat 22, that is, when the partition piece 222 is not arranged, the surface of the connecting seat 22 facing the supporting portion 111 is in direct contact with the supporting portion 111, and thus, the wear resistance of the partition piece 222 is greater than that of the surface of the connecting seat 22 facing the supporting portion 111, that is, by arranging the partition piece 222 on the bottom wall of the sliding groove 221, the connecting seat 22 is in contact with the supporting portion 111 through the partition piece 222, and the partition piece 222 has higher wear resistance, that is, the wear resistance of the contact part of the connecting seat 22 and the supporting portion 111 is improved.

[0045] It should be noted that in the embodiments of the present application, the wear resistance of the related structure can be obtained by a wear test. For example, a pin-on-disc wear test can be used to obtain the wear resistance. A cylindrical pin (representing the material to be tested) is pressed on a rotating disc (simulating the friction surface), and the friction is carried out under certain load, rotation speed and time conditions, and then the wear amount of the pin is measured. The wear amount can be determined by measuring the mass loss and size change of the pin before and after the test. Alternatively, a three-body wear test can be used, in which abrasive particles are added between the friction pairs to simulate a more complex wear environment to evaluate the wear resistance of the material in the abrasive environment. In the wear resistance test, the wear rate can be used to measure the wear resistance. The wear rate refers to the wear amount of the material per unit time or per unit friction distance. The wear amount is usually expressed by volume, mass or thickness. For example, the wear rate can be expressed as the mass loss of the material per kilometer of friction distance (mg / km) or the volume loss of the material per hour of friction process (mm3 / h), etc. 3

[0046] It can be understood that the higher the hardness of the material, the better the wear resistance. In the embodiments, the spacer 222 can be made of a material with higher hardness, i.e., the hardness of the spacer 222 is greater than the hardness of the connecting seat 22 and the support part 111.

[0047] The bearing moving device of the embodiments of the present application, as shown in Figures 1 to 3 By arranging the spacer 222 between the connecting seat 22 and the support part 111, the spacer 222 replaces the direct contact between the connecting seat 22 and the support part 111. In use, the device to be moved is placed on the bearing seat 21, the connecting seat 22 moves along the length direction of the track 11 (as shown by the arrow X in Figure 1 The connecting seat 22 and the device to be moved move together, and during the movement, the connecting seat 22 does not directly contact the support part 111 of the track 11, but directly contacts the support part 111 of the track 11 through the spacer 222. The friction exists between the spacer 222 and the support part 111. On this basis, the wear resistance of the spacer 222 is greater than the wear resistance of the surface of the connecting seat 22 directly opposite to the support part 111. The spacer 222 is not easy to be worn. Compared with the direct contact between the connecting seat 22 and the support part 111, the risk of increased friction between the connecting seat 22 and the support part 111 due to structural damage is reduced. The moving efficiency of the device to be moved is improved. By arranging the spacer 222 with higher wear resistance, compared with improving the wear resistance of the connecting seat 22 or the support part 111 as a whole, the cost is lower, and the practicality is stronger.

[0048] In some embodiments, as shown in Figures 1 to 3 ​As shown, the length of the partition 222 is greater than or equal to the length of the sliding groove 221 along the extension direction of the support portion 111.

[0049] In the embodiment, the length of the partition 222 is greater than or equal to the length of the sliding groove 221 along the extension direction of the support portion 111 (as shown by the direction of the arrow X in FIG. 6), i.e., along the length direction of the track 11. The partition 222 fills the entire sliding groove 221 in the length direction, so that the positions between the connecting seat 22 and the support portion 111 are all separated by the partition 222, and the connecting seat 22 does not directly contact the support portion 111. Figure 1

[0050] In some embodiments, as shown, the width of the partition 222 is greater than or equal to the width of the support portion 111 along a direction perpendicular to the extension direction of the support portion 111 (as shown by the direction of the arrow Y in FIG. 6). Figures 1 to 3 Figure 1 In the embodiment, the width of the partition 222 is greater than or equal to the width of the support portion 111 along a direction perpendicular to the extension direction of the support portion 111, i.e., along the width direction of the support portion 111. In this way, the width of the partition 222 can completely cover the width of the support portion 111, so that the support portion 111 can be separated from the connecting seat 22 by the partition 222 in the width direction.

[0051] In some embodiments, as shown, the support assembly 10 further includes a support frame 12, and the track 11 is arranged on the support frame 12. The support frame 12 provides support for the track 11, i.e., the track 11 is mounted on the support frame 12, and the track 11 can move with the support frame 12. In actual use, the support frame 12 can be moved according to specific use requirements to move the track 11 to the position where the device to be moved is located. In addition, the support frame 12 supports the track 11, so that the track 11 can be lifted by the support frame 12. When the device to be moved is connected to the connecting seat 22, the bottom of the device to be moved is separated from the original mounting surface such as the ground, and does not rub against the mounting surface during movement.

[0052] In some embodiments, the partition 222 and the connecting seat 22 are detachably connected. Figures 1 to 3 That is, the partition 222 is a detachable and replaceable structural member clamped between the connecting seat 22 and the support portion 111. In this way, when the partition 222 is severely worn, a new partition 222 can be replaced, so that the partition 222 can always effectively separate the support portion 111 and the connecting seat 22.

[0053] In some embodiments, the partition 222 and the connecting seat 22 are detachably connected.

[0054] That is, the partition 222 is a detachable and replaceable structural member clamped between the connecting seat 22 and the support portion 111. In this way, when the partition 222 is severely worn, a new partition 222 can be replaced, so that the partition 222 can always effectively separate the support portion 111 and the connecting seat 22.

[0055] ​​It should be noted that the replacement condition of the partition piece 222 can be designed according to specific needs, for example, the change of the friction resistance between the partition piece 222 and the support part 111 can be measured to determine when the friction resistance is greater than a certain preset value, a new partition piece 222 is replaced; or, the height change of the device to be moved relative to the track 11 can also be detected to determine when the height of the device to be moved relative to the track 11 decreases to a certain preset value, indicating that the partition piece 222 is worn and has a significant thickness reduction, at which time a new partition piece 222 is replaced.

[0056] In some embodiments, as shown in Figures 3 to 4 The partition piece 222 is interference-fitted in the sliding groove 221.

[0057] In specific embodiments, the partition piece 222 is slightly larger in size than the sliding groove 221, so that when the partition piece 222 is installed in the sliding groove 221, a certain external force needs to be applied to press or push it into the sliding groove 221, that is, the partition piece 222 is interference-fitted in the sliding groove 221. In this way, it can be ensured that the partition piece 222 and the sliding groove 221 have a tight connection and will not easily loosen or fall off, and when the partition piece 222 needs to be replaced, the external force can also be applied to remove the partition piece 222.

[0058] In other embodiments, as shown in Figures 2 to 4 The connecting seat 22 includes a bottom plate 223 and first and second limiting blocks 224 and 225 installed on the bottom plate 223, the first and second limiting blocks 224 and 225 are arranged in parallel and spaced apart to form the sliding groove 221, the partition piece 222 is clamped between the first and second limiting blocks 224 and 225, and the carrier seat 21 is connected to the bottom plate 223.

[0059] The bottom plate 223 is the basic component of the connecting seat 22, which supports and fixes other components including the support part 111. Exemplarily, the bottom plate 223 can be a flat plate structure of various shapes and sizes. The first and second limiting blocks 224 and 225 are installed on the bottom plate 223, and the first and second limiting blocks 224 and 225 are arranged in parallel and spaced apart to form the sliding groove 221. The connecting seat 22 is connected by interference-fitting with the support part 111 of the track 11 through the sliding groove 221, so as to limit the connecting seat 22 to move only along the length direction of the track 11. The shape and size of the sliding groove 221 depend on the structure and size of the support part 111 and the partition piece 222, so as to accommodate the partition piece 222 and achieve sliding interference-fitting connection with the support part 111.

[0060] In this way, the partition 222 is clamped between the first limiting block 224 and the second limiting block 225, and the first limiting block 224 and the second limiting block 225 provide a holding force to fix the partition 222, so that the partition 222 is not easy to loosen or fall off. When the partition 222 needs to be replaced, an external force is applied to take out the partition 222 from between the first limiting block 224 and the second limiting block 225.

[0061] In some embodiments, as shown in Figure 2 , and Figures 4 to 6 , along the direction in which the first limiting block 224 points to the second limiting block 225 (as shown by the direction of the arrow Y in Figure 2 and Figure 5 ), that is, along the width direction of the sliding groove 221 and the partition 222, the side of the first limiting block 224 towards the second limiting block 225 is provided with a first clamping groove 2241, and one side of the partition 222 is clamped into the first clamping groove 2241. In this way, the first clamping groove 2241 is arranged on the side of the first limiting block 224 to adapt to the clamping of one side of the partition 222, so as to improve the installation reliability and stability of the partition 222 in the sliding groove 221.

[0062] In other embodiments, as shown in Figure 2 , and Figures 4 to 6 , along the direction in which the first limiting block 224 points to the second limiting block 225, the side of the second limiting block 225 towards the first limiting block 224 is provided with a second clamping groove 2251, and the other side of the partition 222 opposite to the one side is clamped into the second clamping groove 2251.

[0063] That is, the first limiting block 224 and the second limiting block 225 are respectively provided with the first clamping groove 2241 and the second clamping groove 2251, and the first clamping groove 2241 and the second clamping groove 2251 are used for adapting to the clamping of the opposite two sides of the partition 222. The partition 222 is limited by cooperation of the first clamping groove 2241 and the second clamping groove 2251. When installed, the two sides of the partition 222 are inserted into the first clamping groove 2241 and the second clamping groove 2251, respectively, and the partition 222 does not need to be connected in an interference manner, and the installation and disassembly of the partition 222 are more flexible and convenient.

[0064] In specific embodiments, along the length direction of the track 11, the first clamping groove 2241 penetrates through the opposite two ends of the first limiting block 224, and the second clamping groove 2251 penetrates through the opposite two ends of the second limiting block 225, so that the partition 222 can be inserted or taken out from any end of the first limiting block 224 and the second limiting block 225.

[0065] In some embodiments, as shown in Figure 2 , and Figures 4 to 6As shown, the first limiting block 224 is provided with a first step portion 2242 towards the side of the bottom plate 223, the second limiting block 225 is provided with a second step portion 2252 towards the side of the bottom plate 223, the bottom plate 223 and the first step portion 2242 form a first clamping groove 2241, and the bottom plate 223 and the second step portion 2252 form a second clamping groove 2251.

[0066] In the embodiment, the first clamping groove 2241 is formed by the bottom plate 223 and the first limiting block 224, and the second clamping groove 2251 is formed by the bottom plate 223 and the second limiting block 225, so that only the step structure of the first limiting block 224 and the second limiting block 225 needs to be formed inwardly during manufacturing.

[0067] In some embodiments, the first limiting block 224 and the second limiting block 225 are detachably connected with the bottom plate 223, so as to facilitate replacement of the partition 222, and the size of the sliding groove 221 can be adjusted according to the size of the support portion 111, so that the same sliding assembly 20 can be used with rails 11 of different sizes, thereby enabling the rails 11 with different sizes of support portions 111 to be selected and used according to the weight or size of the device to be moved.

[0068] In specific embodiments, the first limiting block 224 and the second limiting block 225 can be screwed to the bottom plate 223, as shown in Figure 2 and Figure 5 As shown, the first limiting block 224 is provided with a first step portion 2242 towards the side of the bottom plate 223, the second limiting block 225 is provided with a second step portion 2252 towards the side of the bottom plate 223, the bottom plate 223 and the first step portion 2242 form a first clamping groove 2241, and the bottom plate 223 and the second step portion 2252 form a second clamping groove 2251.

[0069] In some embodiments, the partition 222 is any one of a metal polytetrafluoroethylene material, an ultra-high molecular weight polyethylene material, a silicon carbide ceramic material, an aluminum oxide ceramic material, and a metal ceramic material.

[0070] The metal polytetrafluoroethylene is a composite material, polytetrafluoroethylene (PTFE) has a very low friction coefficient, generally between 0.04 and 0.2, which means that it produces very small friction when in contact with the surface of other objects and moves relatively, while the metal part can provide certain strength and hardness to the material. When the partition 222 is made of metal polytetrafluoroethylene material, the low friction coefficient of polytetrafluoroethylene can effectively reduce the friction and wear when the partition 222 moves or rubs with the support portion 111, while the metal component helps to maintain the overall shape and structural stability of the partition 222, so that it can withstand certain pressure and friction without being easily damaged during long-term use.

[0071] The molecular weight of the ultra-high molecular weight polyethylene is very high, usually above 1.5 million, and it has excellent wear resistance, which is about 7 times that of carbon steel. The molecular chain of the ultra-high molecular weight polyethylene is long and entangled, which makes it have good impact resistance and self-lubricating property. The use of the separator 222 made of ultra-high molecular weight polyethylene makes the surface wear degree very low in the frequent friction environment, and the self-lubricating property can further reduce the friction with the surface of the chute 221, reduce the heat and wear caused by friction, and prolong the service life of the separator 222.

[0072] Both silicon carbide ceramic and aluminum oxide ceramic are materials with high hardness. Because of their high hardness, the separator 222 made of silicon carbide ceramic and aluminum oxide ceramic material is not easy to be scratched or worn when in contact with the support part 111, thereby reducing the risk of increased moving resistance caused by wear of the separator 222 itself.

[0073] Metal ceramic is a composite material composed of ceramic phase and bonding metal phase. It combines the high hardness and wear resistance of ceramic with the toughness of metal. In this way, the separator 222 made of metal ceramic material can resist wear caused by friction during work, and the metal phase can buffer and absorb external impact force, reducing the risk of fracture of the separator 222 due to the brittleness of the material, leading to the failure of the separator.

[0074] In this way, using any one of the metal polytetrafluoroethylene material, the ultra-high molecular weight polyethylene material, the silicon carbide ceramic material, the aluminum oxide ceramic material, and the metal ceramic material to make the separator 222 can effectively separate the connecting seat 22 and the support part 111, and effectively improve the wear resistance between the contact part of the support part 111 and the connecting seat 22, reduce the sliding friction between the support part 111 and the connecting seat 22, and improve the moving efficiency of the device to be moved.

[0075] It can be understood that the separator 222 is any one of the metal polytetrafluoroethylene material, the ultra-high molecular weight polyethylene material, the silicon carbide ceramic material, the aluminum oxide ceramic material, and the metal ceramic material, i.e. the separator 222 can be a metal polytetrafluoroethylene material, or the separator 222 can be an ultra-high molecular weight polyethylene material, or the separator 222 can be a silicon carbide ceramic material, or the separator 222 can be an aluminum oxide ceramic material, or the separator 222 can also be a metal ceramic material.

[0076] In specific embodiments, the separator 222 is a metal polytetrafluoroethylene material, wherein the metal can be copper powder, and the mass percentage of copper powder in the unit mass of the separator 222 is 60%.

[0077] Another embodiment of the present application also provides a maintenance system, comprising the carrying and moving device in any of the above embodiments, and the carrying and moving device is used to carry and move the device to be maintained.

[0078] In the embodiments of the present application, the carrying and moving device provided in the above embodiments is used to move the device to be maintained to the maintenance position. In use, the device to be maintained is connected with the carrying seat 21 of the carrying and moving device, then the connecting seat 22 is pushed to move along the track 11, the connecting seat 22 moves along the length direction of the track 11 and drives the carrying seat 21 and the device to be maintained to move together. Since the separating piece 222 is arranged between the connecting seat 22 and the supporting part 111 of the carrying and moving device, the separating piece 222 is not easy to be worn, the risk of increasing the friction force between the connecting seat 22 and the supporting part 111 of the track 11 due to the structural damage is reduced, the moving efficiency of the device to be maintained is improved, and the overall maintenance efficiency is improved.

[0079] The above description of the various embodiments tends to emphasize the differences between the various embodiments, and the same or similar parts can be referred to each other, and for the sake of brevity, the same or similar parts will not be described herein.

[0080] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
