Description

Technical Field

[0001] This application belongs to the technical field of nuclear power plant maintenance. More specifically, it relates to a load-carrying mobile device and a maintenance system having the same. Background Art

[0002] Nuclear power devices need to be regularly maintained. When maintaining a transformer, a mobile device is required to move the transformer to the maintenance position.

[0003] In related technologies, a method of using piers in cooperation with jacks and tracks to move the transformer is often adopted. During operation, first move the piers to the special vertex positions at the four corners of the transformer, then use the jacks in cooperation to lift the transformer, and then move the tracks under the transformer and connect the transformer to the sliding support structure provided on the tracks. In this way, a sliding support structure is slidably connected to the tracks, and the transformer is supported on the tracks through the sliding support structure and can move along the tracks 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] During the actual operation process, the transformer is heavy, there is a large frictional resistance between the sliding support structure and the steel rail, and different transformers have different weights. Therefore, when moving different transformers, the frictional force between the sliding support structure and the steel rail is also different, and the requirements for the external thrust to push the transformer to move are also different. During the actual operation process, when moving different transformers, it is necessary to adjust the driving force multiple times to drive the transformer to move smoothly. The driving force adjustment process takes a long time and has low efficiency, which is not conducive to improving the moving efficiency of the transformer. Moreover, due to the large volume and weight of the transformer, there may also be risks such as the transformer suddenly moving quickly due to an excessive instantaneous increase in the driving force during the adjustment process, resulting in the transformer tipping over or derailing, etc., posing a greater safety hazard. Summary of the Invention

[0015] In some embodiments, the clamping assembly further includes a second jack, which is clamped between the second clamping part and the auxiliary clamping seat and is used to apply a jacking force along the second direction to the auxiliary clamping seat.

[0016] In some embodiments, the clamping assembly further includes a limiting member disposed between the first clamping part and the second clamping part. The limiting member has a limiting groove that penetrates through opposite ends of the limiting member along the first direction. The connecting seat and the auxiliary clamping seat are respectively detachably connected to the limiting member, and the supporting part is adapted to pass through the limiting groove.

[0017] In some embodiments, the supporting assembly further includes a support frame. The track is disposed on the support frame, and the driving member is installed on the track and / or the support frame. The driving shaft is detachably connected to the connecting seat and the bearing seat.

Before moving a device to be moved, first install the clamping component on the supporting part, so that the clamping piece and the supporting part cooperate to clamp the bearing seat and the connecting seat on the supporting part. The clamping force is used by the clamping component to simulate the gravity of the device to be moved. When the two forces act on the supporting part, the frictional force generated between them and the supporting part is basically the same. At this time, the driving force applied by the driving component is the external thrust required to push the current device to be moved to slide smoothly. In this way, the force simulation of the current device to be moved when moving along the track can be completed; Subsequently, detach the clamping component from the supporting part, and then place the device to be moved on the bearing seat, and start the driving component or an external driving device to provide the corresponding driving thrust. In this way, for devices to be moved with different weights, only the pressure applied by the first jack needs to be adjusted correspondingly to obtain the driving force required to drive its movement, without having to place each device to be moved on the bearing seat and then adjust and test the driving force. On the one hand, multiple devices to be moved with different weights can be simulated and analyzed centrally, and the transfer efficiency of the devices to be moved is improved. On the other hand, the driving force to drive the movement of the device to be moved can be obtained without placing the device to be moved on the supporting part. There is no risk of derailment or rollover of the device during the adjustment of the driving force, and the transfer of the device to be moved is safer and more reliable.

[0048] The nuclear power device needs to be overhauled regularly. When overhauling the transformer, a moving device is required to move the transformer to the overhaul position.

[0049] In the related art, the method of using piers in cooperation with jacks and tracks is often adopted to move the transformer. During operation, first move the piers to the special vertex positions at the four corners of the transformer, then use the jacks in cooperation to lift the transformer, and then move the tracks under the transformer and connect the transformer to the sliding support structure provided on the tracks. In this way, the sliding support structure is slidably connected to the track, and the transformer is supported on the track through 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 overhaul position.

[0050] During the actual operation process, the transformer is heavy, there is a large frictional resistance between the sliding support structure and the steel rail, and different transformers have different weights. Therefore, when moving different transformers, the frictional force between the sliding support structure and the steel rail is also different, and the requirements for the external thrust to push the transformer to move are also different. During the actual operation process, when moving different transformers, it is necessary to adjust the driving force multiple times to drive the transformer to move smoothly and smoothly. The driving force adjustment process takes a long time and has low efficiency, which is not conducive to improving the moving efficiency of the transformer. Moreover, due to the large volume and weight of the transformer, there may also be risks such as the transformer suddenly moving quickly and tipping over or derailing due to an excessive instantaneous increase in the driving force during the adjustment process, posing a great safety hazard.

[0051] Based on this, the embodiments of the present application provide a carrying and moving device to solve the above problems.

[0052] Please refer to Figures 1 to 10 The load-carrying mobile device provided by the embodiments of the present application is applicable but not limited to moving large equipment and devices including transformers when detecting the equipment in a nuclear power plant. In addition, it can also be used to simulate the forces during the movement of equipment and devices such as transformers. It should be noted that in each embodiment, the first direction is the direction indicated by arrow X in the figure, the length direction of the track is the same as the first direction, the second direction is the direction indicated by arrow Z in the figure, the height direction of the track is the same as the second direction, the third direction is the direction indicated by arrow Y in the figure, and the width direction of the track is the same as the third direction.

[0053] In the embodiments of the present application, as Figures 1 to 5 shown, the load-carrying mobile device includes a support assembly 10, a sliding assembly 20, a clamping assembly 30, and a driving member 40. The support assembly 10 includes a track 11 having a support portion 111, and the support portion 111 extends along the length direction of the track 11; the sliding assembly 20 includes a carrier seat 21 and a connecting seat 22 connected to the carrier seat 21, and the connecting seat 22 is slidably installed on the support portion 111, and the carrier seat 21 is used to carry an external device to be moved; the clamping assembly 30 is detachably installed on the support portion 111 and can move synchronously with the sliding assembly 20 along the length direction of the support portion 111. The clamping assembly 30 includes a clamping member 31 and a first jack 32. The clamping member 31 cooperates with the support portion 111 to clamp the carrier seat 21 and the connecting seat 22, and the first jack 32 is clamped between the clamping member 31 and the carrier seat 21 and is used to apply different clamping forces to the carrier seat 21; the drive shaft 41 of the driving member 40 is connected to at least one of the connecting seat 22 and the carrier seat 21 to drive the sliding assembly 20 and the clamping assembly 30 to move together along the length direction of the track.

[0054] In this embodiment, the load-carrying mobile device includes a support assembly 10. The support assembly 10 is used to support the device to be moved. The device to be moved is lifted by the support assembly 10 and does not contact the installation surface such as the ground. During the movement, there is no contact and no frictional resistance with the installation surface such as the ground. Among them, the support assembly 10 includes a track 11. The track 11 extends a certain length along the first direction. The track 11 also has a support portion 111, and the support portion 111 is used to support the device to be moved so that the device to be moved can move along the track 11.

[0055] In this embodiment, the load-carrying mobile device further includes a sliding assembly 20. The sliding assembly 20 is used to connect the device to be moved to the track 11, and the sliding assembly 20 can also move along the length direction of the track 11, that is, the first direction, so as to drive the device to be moved to move synchronously along the length direction of the track 11. Among them, the sliding assembly 20 includes a carrier 21 and a connecting seat 22. The connecting seat 22 is snap-connected to the supporting portion 111 of the track 11 through a chute 221. The carrier 21 is connected to the connecting seat 22, and the carrier 21 carries the device to be moved.

[0056] In this embodiment, the load-carrying mobile device further includes a clamping assembly 30. The clamping assembly 30 is used to clamp the carrier 21 and the connecting seat 22 to the supporting portion 111, so as to simulate the force condition when the device to be moved moves along the track 11, in order to obtain the driving force required to drive the device to be moved to move smoothly along the track 11. Among them, smooth movement means that the device to be moved moves at a constant speed along the track, or accelerates or decelerates with a small acceleration. The clamping assembly 30 is detachably installed on the supporting portion 111. Specifically, when force simulation is required, it is installed on the supporting portion 111. When the force simulation is completed and the device to be moved needs to be actually moved, the clamping assembly 30 is detached from the supporting portion 111, and the clamping assembly 30 will not interfere with the normal movement of the device to be moved.

[0057] In this embodiment, the clamping assembly 30 includes a clamping member 31 and a first jack 32. The clamping member 31 is used to cooperate with the supporting portion 111 to clamp the carrier 21 and the connecting seat 22 to the carrier. The first jack 32 is arranged between the clamping member 31 and the carrier 21 and is used to apply a pressure towards the supporting portion 111 to the carrier 21, that is, to apply a clamping force that clamps the carrier 21 and the connecting seat 22 between the supporting portion 111 and the clamping member 31. Before moving a certain device to be moved, first install the clamping assembly 30 on the supporting portion 111, so that the clamping member 31 cooperates with the supporting portion 111 to clamp the carrier 21 and the connecting seat 22 on the supporting portion 111. Subsequently, start the first jack 32 to apply pressure to the carrier 21. The carrier 21 transmits this pressure to the connecting seat 22, so that the connecting seat 22 abuts against the supporting portion 111 with a certain pressure. Since for a specific device to be moved, such as a transformer, its weight is known or can be measured through measurement. Thus, according to the gravity of the device to be moved, adjust the pressure applied by the first jack 32 to the carrier 21 to be equal to the weight of the device to be moved, and then start the driving member 40 to gradually adjust the driving force to push the sliding assembly to slide smoothly along the length direction of the supporting portion 111, and the thrust required to move the current device to be moved can be obtained. Among them, when simulating force analysis, the driving force is provided by the driving member 40. When actually moving the device to be moved, the driving force can be provided by the driving member 40 or by other external driving devices.

[0058] Thus, in the embodiment of the present application, by providing a clamping assembly 30 on the supporting portion 111 of the track 11, the clamping assembly 30 is detachably mounted on the supporting portion 111. Before moving a device to be moved, first mount the clamping assembly 30 to the supporting portion 111, so that the clamping member 31 cooperates with the supporting portion 111 to clamp the carrier seat 21 and the connecting seat 22 on the supporting portion 111. The clamping force is applied by the clamping assembly 30 to simulate the gravity of the device to be moved. When the two forces act on the supporting portion 111, the frictional forces generated between them and the supporting portion 111 are substantially the same. At this time, the driving force applied by the driving member 40 is the external thrust required to correspondingly push the device to be moved smoothly and slide. In this way, the force simulation of the device to be moved along the track can be completed. Subsequently, detach the clamping assembly 30 from the supporting portion 111, and then place the device to be moved on the carrier seat 21, and start the driving member 40 or an external driving device to provide the corresponding driving thrust. In this way, for devices to be moved with different weights, only the pressure applied by the first jack 32 needs to be correspondingly adjusted to obtain the driving force required to drive its movement, without having to place each device to be moved on the carrier seat 21 and then adjust and test the driving force. On the one hand, multiple devices to be moved with different weights can be centrally simulated and analyzed, improving the transfer efficiency of the devices to be moved. On the other hand, the driving force for driving the device to be moved can be obtained without placing the device to be moved on the supporting portion 111. During the adjustment process of the driving force, there is no risk of derailment or rollover of the device, and the transfer of the device to be moved is safer and more reliable.

[0059] In some embodiments, as Figure 1 and Figure 2 shown, the supporting portion 111 includes a first sub-portion 1111 and a second sub-portion 1112 that extend along a first direction and are spaced apart along a second direction. The first direction is the length direction of the track 11, the second direction is perpendicular to the first direction, and the second direction is the height direction of the track 11. The connecting seat 22 is slidably mounted above the first sub-portion 1111 along the second direction, and the clamping member 31 is slidably connected to the second sub-portion 1112 along the first direction.

[0060] The connecting seat 22 and the bearing seat 21 are installed above the first sub - part 1111 along the second direction, i.e., the height direction of the track 11. The clamping member 31 is connected to the second sub - part 1112, so that the clamping member 31 can cooperate with the second sub - part 1112 of the support part 111 along the height direction of the track 11 to clamp the bearing seat 21 and the connecting seat 22. Among them, when the track 11 is placed on a horizontal installation surface such as the ground, the height direction of the track 11 is the same as the gravity direction of the device to be moved. The clamping member 31 is slidably connected to the second sub - part 1112 along the first direction, i.e., the length direction of the track 11, and the clamping member 31 can move synchronously with the sliding assembly 20 along the length direction of the track 11 relative to the second sub - part 1112. Among them, the clamping member 31 is connected to the second sub - part 1112 through a sliding connection structure. For example, by setting structures such as guide rails and guide grooves on the second sub - part 1112, the slider or protrusion of the clamping member 31 can be made to cooperate with it to achieve sliding, etc.

[0061] In a specific embodiment, the clamping assembly 30 further includes an auxiliary clamping seat 33 arranged below the second sub - part 1112 along the second direction. The auxiliary clamping seat 33 is slidably connected to the second sub - part 1112 along the first direction. The clamping member 31 includes a first clamping part 311 and a second clamping part 312 arranged oppositely along the second direction. The bearing seat 21, the connecting seat 22, the first sub - part 1111, the second sub - part 1112 and the auxiliary clamping seat 33 are sequentially clamped between the first clamping part 311 and the second clamping part 312. The first jack 32 is clamped between the first clamping part 311 and the bearing seat 21, and the first jack 32 is used to apply different magnitudes of pressure to the bearing seat 21 along the second direction.

[0062] Among them, the auxiliary clamping seat 33 is provided with a guide groove 331, and the second sub - part 1112 can be adaptively clamped into the guide groove 331, so that the auxiliary clamping seat 33 can slide along the second sub - part 1112. The clamping member 31 is clamped and connected to the bearing seat 21 and the auxiliary clamping seat 33 through the cooperation of the first clamping part 311 and the second clamping part 312, so that the clamping assembly 30 can slide synchronously with the sliding assembly 20 along the length direction of the track 11 as a whole.

[0063] In some embodiments, such as Figure 1 and Figure 2 shown, the clamping assembly 30 further includes a second jack 34. The second jack 34 is clamped between the second clamping part 312 and the auxiliary clamping seat 33 and is used to apply a jacking force along the second direction to the auxiliary clamping seat 33. Among them, the second jack 34 is used to support the auxiliary clamping seat 33 along the second direction. At the same time, the second jack 34 can also provide an upward jacking force along the second direction. The resultant force of its upward jacking force along the second direction and the downward pressing force provided by the first jack 32 along the second direction is used as the clamping force to clamp the bearing seat 21 and the connecting seat 22 to the first sub - part 1111.

[0064] In some embodiments, Figure 1 and Figure 2 As shown, the clamping assembly 30 also includes a limiting member 35 arranged between the first clamping portion 311 and the second clamping portion 312, the limiting member 35 has a limiting groove 351 that passes through the opposite ends of the limiting member 35 along the first direction, the connecting seat 22 and the auxiliary clamping seat 33 are respectively detachably connected to the limiting member 35, and the support portion 111 is adapted to be passed through the limiting groove 351.

[0065] In this embodiment, the limiter 35 is provided through the support portion 111 by setting a limiter groove 351, and the limiter 35 connects the auxiliary clamping seat 33 and the connecting seat 22, so as to play the role of positioning and connecting the auxiliary clamping seat 33 and the connecting seat 22, so that the auxiliary clamping seat 33 and the connecting seat 22 are both connected to the support portion 111 in a fixed position, thereby reducing the risk of shaking of the auxiliary clamping seat 33 and the connecting seat 22 and improving the accuracy of the simulated force. It can be understood that the limiter 35 and the connecting seat 22 are detachably connected, so that the clamping assembly 30 can be detached from the support portion 111 as a whole, and the limiter 35 and the auxiliary clamping member 31 can be fixedly connected, or can also be detachably connected.

[0066] In some embodiments, Figure 1 , Figure 2 and Figure 5 As shown, the support assembly 10 further includes a support frame 12, and the track 11 is disposed on the support frame 12. The support frame 12 provides support for the track 11, that is, the track 11 is mounted on the support frame 12, and the track 11 can move with the support frame 12. During 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, and the support frame 12 supports the track 11, so that the track 11 can be raised 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 installation surface such as the ground, and no friction occurs with the installation surface during the movement.

[0067] In some embodiments, Figure 1 As shown, the driving member 40 is installed on the track 11 and / or the support frame 12 , and the driving shaft 41 of the driving member 40 is extended along the first direction, and the driving shaft 41 is detachably connected to the connecting seat 22 and the bearing seat 21 .

[0068] In a specific embodiment, the driving member 40 can be installed on the track 11, for example, installed on the supporting portion 111, or the driving member 40 can also be installed on the support frame 12, or the driving member 40 can be installed on the track 11 or the support frame 12 simultaneously. In this way, the driving member 40 can move together with the track 11, which is convenient and flexible to use. Moreover, the driving shaft 41 of the driving member 40 is detachably connected to the connecting seat 22 and the bearing seat 21. By replacing the driving member 40 with different specifications, a larger or smaller driving force range can be obtained. In addition, when using an external driving device to drive the device to be moved, the driving shaft 41 can also be detached to reduce the interference risk.

[0069] In some embodiments, as Figures 3 to 5 shown, the connecting seat 22 is provided with a sliding groove 221 for the first sub-portion 1111 to be adaptively clamped. The sliding groove 221 is provided with a separating member 222 on the bottom wall facing the first sub-portion 1111. The separating member 222 is clamped between the connecting seat 22 and the first sub-portion 1111, and the wear resistance of the separating member 222 is greater than the wear resistance of the surface of the connecting seat 22 facing the first sub-portion 1111.

[0070] In this embodiment, the sliding groove 221 is provided with a separating member 222 on the bottom wall facing the first sub-portion 1111. The separating member 222 is clamped between the connecting seat 22 and the first sub-portion 1111, and the wear resistance of the separating member 222 is greater than the wear resistance of the surface of the connecting seat 22 facing the first sub-portion 1111.

[0071] It can be understood that the wear resistance refers to the property of a material to resist wear. Among them, wear is the process in which the material on the working surface of an object is continuously lost during relative motion. Exemplarily, when an automobile tire travels on the road surface, the surface of the tire is constantly in contact with and rubbed against the ground, and wear will gradually occur; wear will also occur when mutually contacting mechanical structures are in relative motion. For example, when the connecting seat 22 is in direct contact with the first sub-portion 1111 of the track 11, the bottom wall of the sliding groove 221 of the connecting seat 22 is in contact with the first sub-portion 1111, and wear will occur between the two during the movement of the connecting seat 22. Another example is that when the connecting seat 22 is in direct contact with the first sub-portion 1111 through the separating member 222, the separating member 222 is in contact with the first sub-portion 1111, and wear will also occur between the two during the movement of the connecting seat 22.

[0072] The surface of the connecting seat 22 facing the first sub - part 1111 at least includes the surface of the bottom wall of the groove bottom of the connecting seat 22. That is, when the separator 222 is not provided, the surface of the connecting seat 22 facing the first sub - part 1111 is in direct contact with the first sub - part 1111. Thus, the wear resistance of the separator 222 is greater than that of the surface of the connecting seat 22 facing the first sub - part 1111. That is, by providing the separator 222 on the bottom wall of the sliding groove 221, the connecting seat 22 contacts the first sub - part 1111 through the separator 222, and the separator 222 has higher wear resistance, that is, the wear resistance of the contact part between the connecting seat 22 and the first sub - part 1111 is improved.

[0073] It should be noted that in the embodiments of the present application, the wear resistance of relevant structures can be obtained through wear tests. Exemplarily, a pin - on - disk wear test can be used to obtain the wear resistance. A cylindrical pin (representing the material to be tested) is pressed against a rotating disk (simulating the friction surface), and friction is carried out under certain load, rotation speed and time conditions, and then the wear amount of the pin is measured. Among them, the wear amount can be determined by measuring the mass loss, dimensional change, etc. of the pin before and after the test; alternatively, a three - body wear test can also be used, adding abrasive particles between the friction pairs to simulate a more complex wear environment to evaluate the wear resistance of materials in an abrasive - containing environment. Among them, 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, and the wear amount is usually expressed in volume, mass or thickness. For example, the wear rate can be expressed as the mass (mg / km) of the material lost per kilometer of friction distance or the volume (mm 3 / h) etc. of the material lost during the friction process per hour.

[0074] It can be understood that the higher the hardness of the material, the better the wear resistance. In this embodiment, exemplarily, a material with greater hardness can be used to make the separator 222, that is, the hardness of the separator 222 is greater than that of the connecting seat 22 and the first sub - part 1111.

[0075] The load - bearing moving device of this embodiment, such as Figures 5 to 7 shown, by providing a separator 222 between the connecting seat 22 and the first sub - part 1111, the separator 222 replaces the direct contact between the connecting seat 22 and the first sub - part 1111. When using the load - bearing moving device of this embodiment, an external device to be moved is placed on the bearing seat 21, and the connecting seat 22 moves along the length direction of the track 11 (such as Figure 5It moves in the direction indicated by arrow X in the figure and drives the carrier seat 21 and the device to be moved to move together. Moreover, during the moving process, the connecting seat 22 does not directly contact the first sub-part 1111 of the track 11, but directly contacts the first sub-part 1111 of the track 11 through the separator 222. The frictional force exists between the separator 222 and the first sub-part 1111. On this basis, the wear resistance of the separator 222 is set to be greater than the wear resistance of the surface of the connecting seat 22 facing the first sub-part 1111. The separator 222 is not easily worn. Compared with the direct contact between the connecting seat 22 itself and the first sub-part 1111, the risk of the increase in the frictional force due to structural damage between the connecting seat 22 and the first sub-part 1111 of the track 11 is reduced, and the moving efficiency of the device to be moved is improved. Moreover, by setting the separator 222 with higher wear resistance, compared with improving the wear resistance of the connecting seat 22 or the first sub-part 1111 as a whole, the cost is lower and the practicability is stronger.

[0076] It should be noted that in the embodiment of the present application, since different separators 222 have different wear resistances, when the same pressure is applied, the frictional forces between different separators 222 and the first sub-part 1111 are different. Thus, after replacing the separator 222, it is necessary to reinstall the clamping assembly 30 for the simulation analysis of the force to obtain the driving force required to move the device to be moved under the currently used separator 222.

[0077] In some embodiments, as Figures 5 to 7 shown, along the extension direction of the first sub-part 1111, the length of the separator 222 is greater than or equal to the length of the chute 221.

[0078] In this embodiment, along the extension direction of the first sub-part 1111 (such as Figure 5 the direction indicated by arrow X in the figure), that is, along the length direction of the track 11, the length of the separator 222 is greater than or equal to the length of the chute 221. The separator 222 fills the entire chute 221 in the length direction, so that the positions between the connecting seat 22 and the first sub-part 1111 are all separated by the separator 222, and the connecting seat 22 does not directly contact the first sub-part 1111.

[0079] In some embodiments, as Figures 5 to 7 shown, along the direction perpendicular to the extension direction of the first sub-part 1111 (such as Figure 5 the direction indicated by arrow Y in the figure), the width of the separator 222 is greater than or equal to the width of the first sub-part 1111.

[0080] In this embodiment, along a direction perpendicular to the extending direction of the first sub - part 1111, that is, along the width direction of the first sub - part 1111, the width of the separator 222 is greater than or equal to the width of the first sub - part 1111. In this way, the width of the separator 222 can completely cover the width of the first sub - part 1111, so that in the width direction, the first sub - part 1111 can be separated from the connecting seat 22 by the separator 222.

[0081] In some embodiments, the separator 222 is detachably connected to the connecting seat 22.

[0082] That is, the separator 222 is a detachable and replaceable structural member clamped between the connecting seat 22 and the first sub - part 1111. In this way, when the separator 222 is severely worn, a new separator 222 can be replaced so that the separator 222 can always effectively separate the first sub - part 1111 and the connecting seat 22.

[0083] It should be noted that the replacement condition of the separator 222 can be designed according to specific needs. For example, it can be determined by measuring the change in the frictional resistance between the separator 222 and the first sub - part 1111. When the frictional resistance is greater than a certain preset value, a new separator 222 is replaced; or, it can also be determined by detecting the height change of the device to be moved relative to the track 11. When the height of the device to be moved relative to the track 11 is reduced to a certain preset value, it indicates that the separator 222 is worn and its thickness is significantly reduced. At this time, a new separator 222 is replaced.

[0084] In some embodiments, as Figure 7 and Figure 8 shown, the separator 222 is press - fit into the chute 221.

[0085] In a specific embodiment, the size of the separator 222 is set slightly larger than the size of the chute 221, so that when the separator 222 is installed in the chute 221, a certain external force needs to be applied to press it or push it into the chute 221, that is, the separator 222 is press - fit into the chute 221. In this way, it can ensure a tight connection between the separator 222 and the chute 221, and it will not loosen or fall off easily. When the separator 222 needs to be replaced, an external force can also be applied to take out the separator 222.

[0086] In other embodiments, as Figures 6 to 8 shown, the connecting seat 22 includes a bottom plate 223, a first limiting block 224 and a second limiting block 225 installed on the bottom plate 223. The first limiting block 224 and the second limiting block 225 are arranged in parallel at intervals to form the chute 221. The separator 222 is clamped between the first limiting block 224 and the second limiting block 225, and the bearing seat 21 is connected to the bottom plate 223.

[0087] Among them, the bottom plate 223 is the basic component of the connecting seat 22, which plays a role in supporting and fixing other components including the first sub - part 1111. Exemplarily, the bottom plate 223 can be a flat plate structure of various shapes and sizes. The first limiting block 224 and the second limiting block 225 are installed on the bottom plate 223, and the first limiting block 224 and the second limiting block 225 are arranged in parallel at intervals to form a sliding groove 221. The connecting seat 22 is adaptively clamped and connected with the first sub - part 1111 of the track 11 through the sliding groove 221, so as to limit the connecting seat 22 to slide only along the length direction of the track 11. The shape and size of the sliding groove 221 depend on the structures and sizes of the first sub - part 1111 and the partition 222 to meet the requirements of accommodating the partition 222 and the sliding clamping connection with the first sub - part 1111.

[0088] 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 clamping force to fix the partition 222, so that the partition 222 is not easily loosened or fallen 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.

[0089] In some embodiments, as Figure 6 and Figures 8 to 10 shown, along the direction from the first limiting block 224 to the second limiting block 225 (such as the direction indicated by the arrow Y in Figure 6 and Figure 9 ), that is, along the width direction of the sliding groove 221 and the partition 222, a first clamping groove 2241 is provided on the side of the first limiting block 224 facing the second limiting block 225, and one side of the partition 222 is snapped into the first clamping groove 2241. In this way, the first clamping groove 2241 is provided on the side of the first limiting block 224 to adaptively clamp and connect one side of the partition 222, so as to improve the installation reliability and stability of the partition 222 in the sliding groove 221.

[0090] In other embodiments, as Figure 6 and Figures 8 to 10 shown, along the direction from the first limiting block 224 to the second limiting block 225, a second clamping groove 2251 is provided on the side of the second limiting block 225 facing the first limiting block 224, and the opposite side of the partition 222 is snapped into the second clamping groove 2251.

[0091] That is, the first limiting block 224 and the second limiting block 225 are respectively provided with a first card slot 2241 and a second card slot 2251. The first card slot 2241 and the second card slot 2251 are used for the opposite sides of the separator 222 to be adaptively clamped. The separator 222 is limited by the cooperation of the first card slot 2241 and the second card slot 2251. During installation, the two sides of the separator 222 are correspondingly inserted into the first card slot 2241 and the second card slot 2251. The separator 222 does not need to be connected in an interference fit manner, and its installation and disassembly are more flexible and convenient.

[0092] In a specific embodiment, along the length direction of the track 11, the first card slot 2241 penetrates through the opposite ends of the first limiting block 224, and the second card slot 2251 penetrates through the opposite ends of the second limiting block 225, so that the separator 222 can be inserted or taken out from any end of the first limiting block 224 and the second limiting block 225.

[0093] In some embodiments, such as Figure 6 and Figures 8 to 10 shown, a first step portion 2242 is provided on the side of the first limiting block 224 facing the bottom plate 223, and a second step portion 2252 is provided on the side of the second limiting block 225 facing the bottom plate 223. The bottom plate 223 and the first step portion 2242 enclose to form the first card slot 2241, and the bottom plate 223 and the second step portion 2252 enclose to form the second card slot 2251.

[0094] In this embodiment, the first card slot 2241 is jointly formed by the bottom plate 223 and the first limiting block 224, and the second card slot 2251 is jointly formed by the bottom plate 223 and the second limiting block 225. During manufacturing, only a stepped structure that is recessed inward needs to be formed on the first limiting block 224 and the second limiting block 225.

[0095] In some embodiments, the first limiting block 224 and the second limiting block 225 are detachably connected to the bottom plate 223 to facilitate the replacement of the separator 222. When necessary, the size of the sliding groove 221 can also be adjusted according to the size of the first sub - part 1111, so that the same sliding assembly 20 can be used in cooperation with tracks 11 of different sizes, and thus, according to the weight or volume of the device to be moved, a track 11 with a first sub - part 1111 of different sizes can be selected for cooperation.

[0096] In a specific embodiment, the first limiting block 224 and the second limiting block 225 can be screwed to the bottom plate 223, as Figure 6 and Figure 9 shown, and are detachably connected to the bottom plate 223 through fasteners such as screws or bolts. Or, a snap - fit structure can also be provided between the bottom plate 223, the first limiting block 224, and the second limiting block 225 to achieve detachable connection, etc.

[0097] In some embodiments, the separator 222 is any one of a metal polytetrafluoroethylene material piece, an ultra-high molecular weight polyethylene material piece, a silicon carbide ceramic material piece, an alumina ceramic material piece, and a cermet material piece.

[0098] Among them, metal polytetrafluoroethylene is a composite material. Polytetrafluoroethylene (PTFE) has an extremely low coefficient of friction, generally between 0.04 and 0.2. This means that when it comes into contact with the surface of other objects and relative movement occurs, the generated frictional force is very small, while the metal part can provide certain strength and hardness to the material. When the separator 222 is made of metal polytetrafluoroethylene material, when relative movement or frictional contact occurs with the first sub-part 1111, the low coefficient of friction of polytetrafluoroethylene can effectively reduce the frictional force and wear. At the same time, the metal component helps to maintain the overall shape and structural stability of the separator 222, enabling it to withstand certain pressure and friction during long-term use without being easily damaged.

[0099] Ultra-high molecular weight polyethylene has a very high molecular weight, usually above 1.5 million. It has excellent wear resistance, and its wear resistance is about 7 times that of carbon steel. The molecular chains of ultra-high molecular weight polyethylene are long and entangled with each other, giving it good impact resistance and self-lubricity. Using it to make the separator 222 results in extremely low surface wear in a frequent friction environment. Its self-lubricity can further reduce the frictional force with the surface of the chute 221, reducing the heat and wear generated by friction, thereby extending the service life of the separator 222.

[0100] Both silicon carbide ceramics and alumina ceramics are materials with relatively high hardness. Due to their high hardness, when the separator 222 made of silicon carbide ceramic and alumina ceramic materials comes into contact and frictions with the first sub-part 1111, it is not easily scratched or worn itself, thereby reducing the risk of an increase in moving resistance caused by the wear of the separator 222 itself.

[0101] Cermet is a composite material composed of a ceramic phase and a bonding metal phase. It combines the high hardness and high wear resistance of ceramics with the toughness of metals. In this way, during the working process of the separator 222 made of cermet material, the ceramic phase can resist the wear generated by friction, while the metal phase can buffer and absorb external impact forces, reducing the risk of the separator 222 breaking due to material brittleness and resulting in separation failure.

[0102] Thus, a separator 222 is made of any one of a metal polytetrafluoroethylene material part, a ultra-high molecular weight polyethylene material part, a silicon carbide ceramic material part, an alumina ceramic material part, and a cermet material part, so that the separator 222 can effectively separate the connecting seat 22 and the first sub-part 1111, and can effectively improve the wear resistance between the contact parts of the first sub-part 1111 and the connecting seat 22, reduce the sliding friction force between the first sub-part 1111 and the connecting seat 22, and improve the moving efficiency of the device to be moved.

[0103] It can be understood that the separator 222 is any one of a metal polytetrafluoroethylene material part, a ultra-high molecular weight polyethylene material part, a silicon carbide ceramic material part, an alumina ceramic material part, and a cermet material part, that is, the separator 222 can be a metal polytetrafluoroethylene material part, or the separator 222 can be a ultra-high molecular weight polyethylene material part, or the separator 222 can be a silicon carbide ceramic material part, or the separator 222 can be an alumina ceramic material part, or the separator 222 can also be a cermet material part.

[0104] In a specific embodiment, the separator 222 is a metal polytetrafluoroethylene material part, wherein the metal can be copper powder, and in the separator 222 per unit mass, the mass proportion of the copper powder is 60%.

[0105] Another embodiment of the present application further provides an overhaul system, including the load-carrying moving device in any of the above embodiments, and the load-carrying moving device is used to carry and move the device to be overhauled.

[0106] In the embodiment of the present application, the load-carrying moving device provided in the above embodiment is used to move the device to be overhauled to the overhaul position. Before moving a certain device to be overhauled, the clamping assembly 30 is first installed on the support portion 111, and the force on the current device to be overhauled when moving along the track 11 is simulated, so as to obtain the thrust required to push the current device to be overhauled to slide smoothly. Subsequently, the clamping assembly 30 is detached, the device to be overhauled is connected to the carrier seat 21, and then a force approximately the same as the driving force obtained by the simulation analysis is applied to push the connecting seat 22 to move along the track 11. The connecting seat 22 moves along the length direction of the track 11 and drives the carrier seat 21 and the device to be overhauled to move together. Thus, the device to be overhauled can be smoothly moved to the overhaul position, the transfer efficiency of the device to be overhauled is improved, and the moving process is also safer and more reliable, and the overall overhaul efficiency is improved.

[0107] The descriptions of the above embodiments tend to emphasize the differences between the embodiments, and their similarities can be referred to each other. For the sake of brevity, they will not be repeated herein.
