AI Technical Summary
When moving a transformer, especially on a sloping track, the transformer is prone to slippage due to gravity, which can cause it to change position, tip over, or detach from the track, making the move difficult and inefficient.
An anti-slip device is installed on the support part of the track. The anti-slip device includes a connecting part and a force-bearing part. The force-bearing part intersects with the support part. When the force-bearing surface is subjected to thrust, the connecting part is locked to the support part and locked on the track to prevent the transformer from slipping.
It improves the stability and reliability of transformers on the track, reduces the risk of accidental slippage, tipping or derailment, and improves movement efficiency.

Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of nuclear power maintenance, and more particularly to a bearing moving device and a maintenance system with the same. BACKGROUND
[0002] Nuclear power devices need to be regularly maintained, and when transformers are maintained, moving devices need to be used to move the transformers to the maintenance position.
[0003] In related technologies, the transformer is moved by supporting piers cooperating with jacks and rails, wherein the piers are first placed at the special jacking positions at the four corners of the transformer, then the transformer is jacked up by cooperating with the jacks, and then the rails are moved to the lower side of the transformer. The sliding support structure is slidably connected to the rails, and 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.
[0004] In actual operation, when the transformer needs to be moved at a position with a slope, the transformer needs to be moved along the rail with a certain slope. Since the transformer is heavy, when the transformer is located on the rail and is not subjected to the thrust or tension force applied by the external driving device, the transformer will slide along the inclined rail under the action of gravity, thereby deviating from the original position of the transformer. The sliding of the transformer not only causes the position of the transformer to change, but also has the risk of falling or deviating from the sliding rail during the sliding process. The difficulty of moving the transformer increases, and the moving efficiency is difficult to improve. CONTENT OF THE INVENTION
[0005] The purpose of the embodiment of the application is to provide a bearing moving device and a maintenance system with the same, aiming to improve the moving stability and reliability of the transformer and improve the moving efficiency.
[0006] To achieve the above purpose, the technical solution adopted by the application is:
[0007] A bearing moving device is provided, comprising:
[0008] The rail has a support portion extending in a first direction, and the first direction is the length direction of the rail;
[0009] The retreat stopper is installed on the support portion;
[0010] The retreat stopper includes a connecting portion and a force receiving portion. The force receiving portion is protruded from the side portion of the support portion and has a force receiving surface arranged in a direction intersecting the first direction. The connecting portion is connected with the support portion and can be clamped to the support portion when the force receiving surface is subjected to a thrust force.
[0011] In some embodiments, the force receiving portion is arranged in the supporting direction of the supporting portion, and the force receiving surface is perpendicular to the first direction; the force receiving portion is arranged protruding relative to the connecting portion along the first direction, and a side of the force receiving portion away from the connecting portion forms the force receiving surface.
[0012] In some embodiments, the supporting portion has a supporting surface extending along the first direction, and the connecting portion is provided with a clamping groove for fitting and clamping of the supporting portion, and the clamping groove has a first limiting surface;
[0013] In some embodiments, the first limiting surface is separated from or at least partially attached to the supporting surface when the force receiving surface is not subjected to the pushing force, and the side of the first limiting surface away from the force receiving surface is abutted against the supporting surface when the force receiving surface is subjected to the pushing force along the first direction, so that the connecting portion is clamped to the supporting portion.
[0014] In some embodiments, the first limiting surface is arranged obliquely relative to the supporting surface, and the end of the first limiting surface away from the force receiving surface is attached to the supporting surface when the force receiving surface is not subjected to the pushing force.
[0015] In some embodiments, the side of the supporting portion obliquely relative to the supporting surface is provided with a limiting groove, the connecting portion is provided with a limiting protrusion for fitting into the clamping groove, the limiting groove has an abutting surface, and the limiting protrusion has a second limiting surface formed by the surface below the abutting surface along a second direction; the second direction is the supporting direction of the supporting portion.
[0016] In some embodiments, the second limiting surface is separated from or attached to the abutting surface when the force receiving surface is not subjected to the pushing force, and the side of the second limiting surface toward the force receiving surface is abutted against the abutting surface when the force receiving surface is subjected to the pushing force along the first direction, so that the first limiting surface and the second limiting surface clamp the part of the supporting portion between the first limiting surface and the second limiting surface, thereby clamping the connecting portion to the supporting portion.
[0017] In some embodiments, the supporting portion has two sides arranged opposite relative to each other along a third direction, and each side is provided with a limiting groove, and the connecting portion is provided with a limiting protrusion corresponding to the positions of the two limiting grooves; the third direction is perpendicular to the first direction and the second direction.
[0018] In some embodiments, the connecting portion includes a first arm, a second arm, and a connecting arm connecting the first arm and the second arm; the connecting arm is arranged above the supporting portion along the second direction; and the first arm and the second arm are arranged spaced apart along the third direction.
[0019] The first arm, the second arm, and the connecting arm surround to form the clamping groove; the force receiving portion and the first limiting surface are arranged on the connecting arm; and the end of the first arm and the second arm away from the connecting arm is respectively provided with a limiting protrusion, and the surface of the limiting protrusion opposite to the first limiting surface forms a second limiting surface.
[0020] In some embodiments, the limiting protrusion further has a first guide surface arranged opposite to the second limiting surface, and the first guide surface is used for guiding the supporting portion to be clamped into the clamping groove along the second direction.
[0021] In some embodiments, the limiting protrusion is further provided with a second guide surface, which is connected to the second limiting surface and is inclined relative to the first direction. The second guide surface is used to guide the support portion into the slot along the first direction.
[0022] Another technical solution of this application is: a maintenance system, including the above-mentioned carrying and moving device, which is used to carry and move the device to be maintained.
[0023] The beneficial effects of the carrying and moving device provided in this application are as follows: by installing a backstop on the support part of the track, the backstop includes a connecting part and a force-bearing part. The connecting part is connected to the support part, and the force-bearing part protrudes relative to the support part. The force-bearing part has a force-bearing surface, which intersects with the first direction, i.e. the length direction of the track. When the force-bearing surface of the force-bearing part is subjected to a thrust, the connecting part can generate a locking action and tightly lock with the support part, thereby locking the backstop on the support part. Thus, when the track support is tilted in a certain direction, and the external device to be moved is placed on the support without needing to move along the track, the anti-reverse component is placed behind the device to be moved in the tilt direction. Due to gravity, the device to be moved tends to slide along the tilt direction of the support. At this time, the device to be moved can contact the force-bearing surface of the anti-reverse component and provide thrust to the force-bearing surface, so that the anti-reverse component can be locked into the track support through its connecting part to stop the device to be moved. This reduces the risk of the device to be moved accidentally sliding along the track under its own weight, so that the device to be moved can stay stably at a specific position on the track when it does not need to move. The risk of the device to be moved tipping over or derailing due to accidental sliding is also reduced accordingly, which also helps to improve the stability and reliability of the device to be moved during the movement process.

[0033] To make the technical problem to be solved, the technical solution and the beneficial effects of this application clearer, the following is in conjunction with the appendix. Figures 1 to 4 The present application will be further described in detail below with reference to embodiments.

[0037] Nuclear power plants need to be repaired regularly, and when repairing transformers, mobile devices need to be used to move the transformer to the repair position.
[0038] In the related art, the transformer is moved by supporting the pier and cooperating with the jack and the track, wherein the pier is first supported at the special jacking position of the four corners of the transformer, and then the transformer is jacked up by cooperating with the jack, and then the track is moved to the lower side of the transformer. 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 external force, so that the transformer can be transferred to the relevant repair position.
[0039] In actual operation, when the transformer needs to be moved at a position with a slope, the transformer needs to be moved along the track with a certain slope. Since the transformer is heavy, when the transformer is located on the track and is not subjected to the thrust or tension force applied by the external driving device, the transformer will slide along the inclined track under the action of gravity, thereby deviating from the original position of the transformer. The sliding of the transformer not only causes the position of the transformer to change, but also has the risk of falling or deviating from the sliding rail during the sliding process. The difficulty of moving the transformer increases, and the moving efficiency is difficult to improve.
[0040] Therefore, the embodiments of the present application provide a bearing moving device to solve the above problems.
[0041] Please refer to Figures 1 to 4 The retreat-preventing member provided in the embodiments of the present application is suitable for, but not limited to, moving large equipment and devices such as transformers during the repair of equipment in nuclear power plants. In the embodiments of the present application, the first direction, i.e. the length direction of the track, is the direction indicated by arrow F1, the second direction, i.e. the supporting direction of the supporting part, is the direction indicated by arrow F2, and the third direction, i.e. the width direction of the supporting part, is the direction indicated by arrow F3.
[0042] In the embodiments of the present application, as Figures 1 to 4As shown, the carrying and moving device comprises a track 11 and a retreat-stop piece 30, the track 11 has a support part 111 arranged in extension along a first direction, the first direction being the length direction of the track 11; the retreat-stop piece 30 is installed on the support part 111; wherein the retreat-stop piece 30 comprises a connecting part 31 and a force-receiving part 32, the force-receiving part 32 is protruded on the side of the support part 111 and has a force-receiving surface 321 arranged in a direction intersecting the first direction, and the connecting part 31 is connected with the support part 111 and can be clamped on the support part 111 when the force-receiving surface 321 is subjected to a thrust force.
[0043] In the embodiments of the present application, as shown in Figure 1 , The carrying and moving device comprises a track 11, the track 11 is used to provide a moving path for the device to be moved, wherein the track 11 has a support part 111 used to support the device to be moved, the device to be moved is lifted by the support part 111 without contacting the installation surface such as the ground, and there is no frictional resistance between the device to be moved and the installation surface such as the ground during the movement, so that the device to be moved can move along the length direction of the track 11. In some examples, the track 11 can be installed on a support frame 12, the support frame 12 provides support for the track 11, 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 so as 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 lifted by the support frame 12. When the device to be moved is connected with the support part 111, the bottom of the device to be moved is separated from the original installation surface such as the ground, and there is no friction between the device to be moved and the installation surface during the movement.
[0044] In the embodiments of the present application, it can be understood that the device to be moved can be provided with a sliding groove 221 matched with the support part 111, so that the device to be moved can be installed on the support part 111 and moved along the track 11, or the carrying and moving device can also comprise a sliding assembly 20, the device to be moved is connected to the support part 111 of the track 11 through the sliding assembly 20, and the sliding assembly 20 can also move along the length direction of the track 11, so as to drive the device to be moved to move synchronously along the length direction of the track 11. For example, the sliding assembly 20 can comprise a carrying seat 21 and a connecting seat 22, the connecting seat 22 is provided with the sliding groove 221 and is connected to the support part 111 of the track 11 through the sliding groove 221, the carrying seat 21 is connected with the connecting seat 22, and the carrying seat 21 carries the device to be moved.
[0045] In the embodiments of the present application, as shown in Figure 1 , Figure 3 and Figure 4As shown, the bearing mobile device further comprises a retreat-stop piece 30, which is installed on the track 11 by connecting the connecting part 31 of the retreat-stop piece 30 with the supporting part 111 of the track 11, wherein the connecting part 31 can be connected with the supporting part 111 in a sliding fit manner, so that the retreat-stop piece 30 can be adjusted in the installation position of the supporting part 111 by moving along the length direction of the track 11, or the connecting part 31 can also be connected with the supporting part 111 in a detachable manner, so that the retreat-stop piece 30 can be adjusted in the installation position of the supporting part 111 by detaching. The retreat-stop piece 30 further comprises a force-receiving part 32, which is used to bear the external force, and the force-receiving part 32 has a force-receiving surface 321. When the force-receiving surface 321 is subjected to a pushing force, the pushing force is transmitted to the connecting part 31 through the force-receiving part 32, and under the action of this force, the friction or other constraint mechanism between the connecting part 31 and the supporting part 111 will change, for example, the gap between some parts of the connecting part 31 and the supporting part 111 can be reduced or extruded, or some special clamping structures such as spring buckles, wedge structures, etc. can also be triggered, so that the connecting part 31 can be clamped on the supporting part 111, preventing the retreat-stop piece 30 from continuing to move, thereby achieving the function of stopping retreat. Moreover, the force-receiving part 32 is protrudingly arranged on the side of the supporting part 111, the force-receiving surface 321 intersects the first direction, and the supporting part 111 does not block the force-receiving part 32. When the mobile device to be moved moves along the supporting part 111 under the action of its own gravity, or the mobile device to be moved is placed on the supporting part 111 and has a moving trend under the action of its own gravity, the mobile device to be moved can provide a pushing force by contacting the force-receiving surface 321 of the force-receiving part 32, so that the connecting part 31 is clamped on the supporting part 111.
[0046] Therefore, the bearing mobile device provided by the embodiment of the present application can lock the stopper 30 on the support part 111. When the support part 111 of the track 11 is inclined in a certain direction, and the external mobile device is placed on the support part 111 without moving along the track 11, the stopper 30 is placed behind the mobile device in the inclined direction. The mobile device has a tendency to slide along the inclined direction of the support part 111 due to gravity. At this time, the mobile device can be in surface contact with the force receiving part 32 of the stopper 30 and provide a pushing force on the force receiving surface 321, so that the stopper 30 can be clamped on the support part 111 of the track 11 by the connecting part 31 to stop the mobile device, thereby reducing the risk of accidental sliding of the mobile device along the track 11 under its own gravity, so that the mobile device can be stably placed at a specific position on the track 11 when it does not need to move, and the risk of the mobile device falling or derailing due to accidental sliding is also reduced, thereby helping to improve the stability and reliability of the mobile device during movement.
[0047] In some embodiments, as shown in Figure 1 and Figure 4 The force receiving part 32 is arranged in the support direction of the support part 111, and the force receiving surface 321 is perpendicular to the first direction.
[0048] In the embodiment, the support direction of the support part 111 refers to the direction mainly used to bear or support the mobile device, which is opposite to the direction of gravity. For example, if the track 11 is horizontally placed, the support direction of the support part 111 is vertically upward. If the track 11 is inclined or vertically placed, the support direction of the support part 111 is perpendicular to the support plane of the support part 111. The force receiving part 32 is arranged in the support direction of the support part 111, that is, the force receiving part 32 is arranged in the upper space of the straight line direction of the support part 111, that is, the force receiving part 32 is in the same direction as the support direction of the support part 111 in space position. The force receiving part 32 can be directly above the support part 111 (protruding in the support direction), or can have a certain interval with the support part 111 in the support direction, but as a whole, it is in the direction determined by the straight line or extension line of the support direction of the support part 111, so that the force receiving part 32 can effectively receive and transmit the force in the support direction.
[0049] In the embodiment, the force receiving surface 321 is arranged perpendicularly to the first direction, so that when the force receiving surface 321 receives an external force, the direction of the force is perpendicular to the length direction of the track 11. When the to-be-moved device contacts the force receiving surface 321 and exerts a pushing force on the force receiving surface 321, the pushing force is transmitted to the connecting portion 31 in a direction perpendicular to the length direction of the track 11 (i.e., the first direction), and the force perpendicular to the first direction can better cause the connecting portion 31 and the supporting portion 111 to generate a friction force or other clamping force, so that the connecting portion 31 can be clamped to the supporting portion 111 when the force receiving surface 321 is pushed in the first direction, and the retreat stopping piece 30 has a more reliable retreat stopping function to stop accidental sliding of the to-be-moved device.
[0050] In some embodiments, as shown in Figure 1 , Figure 3 and Figure 4 , the force receiving portion 32 is arranged protruding outward relative to the connecting portion 31 along the first direction, and a surface of the force receiving portion 32 away from the connecting portion 31 forms the force receiving surface 321.
[0051] The first direction is the length direction of the track 11, so that the force receiving portion 32 is located on the side of the connecting portion 31 along the length direction of the track 11 and protrudes outward relative to the connecting portion 31 along the length direction. That is, as viewed along the length direction of the track 11, the force receiving portion 32 extends beyond the position range of the connecting portion 31 to a certain end portion of the track 11. On this basis, the surface of the force receiving portion 32 away from the connecting portion 31 forms the force receiving surface 321, so that the to-be-moved device can first contact the force receiving surface 321 before other positions of the retreat stopping piece 30, and the connecting portion 31 of the retreat stopping piece 30 can quickly respond to the pushing force applied to the force receiving surface 321 and be clamped to the supporting portion 111 of the track 11.
[0052] In some embodiments, as shown in Figures 1 to 4 , the supporting portion 111 has a supporting surface 1111 extending along the first direction, and the connecting portion 31 is provided with a clamping groove 311 adapted to clamp the supporting portion 111, and the clamping groove 311 has a first limiting surface 3111; wherein, in the case that the force receiving surface 321 is not subjected to a pushing force, the first limiting surface 3111 is separated from or at least partially attached to the supporting surface 1111, and in the case that the force receiving surface 321 is subjected to a pushing force along the first direction, the side of the first limiting surface 3111 away from the force receiving surface 321 abuts against the supporting surface 1111 to clamp the connecting portion 31 to the supporting portion 111.
[0053] In the embodiment, the support part 111 has a support surface 1111 extending along the first direction (i.e. the length direction of the track 11), which provides a support surface for the connecting part 31 of the stop piece 30 and the to-be-moved device, and extends along the length direction of the track 11 to guide the movement of the to-be-moved device, so as to ensure that the to-be-moved device and the stop piece 30 can be stably supported on the track 11, and the to-be-moved device can stably move on the track 11. The connecting part 31 of the stop piece 30 is provided with a clamping groove 311 which is matched with the support part 111 in shape and size, so that the support part 111 can be clamped into the clamping groove 311, and the connecting part 31 and the support part 111 are connected and matched. In addition, the stop piece 30 is connected with the support part 111 through the clamping groove 311, and the clamping groove 311 and the support part 111 can form a sliding fit structure, so that the stop piece 30 can also move along the length direction of the track 11, thereby adjusting the arrangement position of the support part 111.
[0054] In the embodiment, the clamping groove 311 has a first limiting surface 3111 which plays a role of limiting and positioning in the matching of the connecting part 31 and the support part 111. Specifically, when the force receiving surface 321 is not subjected to the pushing force, the first limiting surface 3111 is separated from or at least partially attached to the support surface 1111. At this time, there is no or only a small extrusion and friction force between the support surface 1111 and the first limiting surface 3111. When the connecting part 31 is connected to the support part 111, in this case, the connecting part 31 can slide relatively freely on the support surface 1111 through the matching of the clamping groove 311 and the support part 111, and the stop piece 30 can smoothly move along the first direction of the track 11, so that the stop piece adjusts the arrangement position of the stop piece 30 on the support part 111 of the track 11 as needed. Figure 4 As shown in FIG. 6, when the force receiving surface 321 is subjected to the pushing force F along the first direction, since the force receiving surface 321 is arranged above the support part 111 and the connecting part 31 is connected to the support part 111 below the force receiving surface 321, under the action of the pushing force, the connecting part 31 will be inclined relative to the support surface 1111 or have a relative inclination movement trend, so that the side of the first limiting surface 3111 away from the force receiving surface 321 (approximately the position indicated by point A in the figure) abuts against the support surface 1111, the connecting part 31 extrudes the support part 111, so that the friction force between the first limiting surface 3111 and the support surface 1111 increases sharply, thereby tightly fixing the connecting part 31 on the support part 111, realizing the clamping of the connecting part 31, and locking the stop piece 30 on the support part 111 of the track 11, so as to stop the to-be-moved device from sliding along the track 11.
[0055] In some embodiments, as shown in FIG. 7, Figures 2 to 3As shown, the first limiting surface 3111 is arranged obliquely relative to the support surface 1111, and in the case where the force receiving surface 321 is not subjected to a pushing force, the end of the first limiting surface 3111 away from the force receiving surface 321 is in abutment with the support surface 1111. In this way, the end of the first limiting surface 3111 away from the force receiving surface 321 is arranged closer to the support portion 111 than the end of the first limiting surface 3111 toward the force receiving surface 321, so that in the case where the force receiving surface 321 is subjected to a pushing force, the side of the first limiting surface 3111 away from the force receiving surface 321 can be in abutment with the support surface 1111 with a greater pressing force, thereby further improving the reliability of the clamping of the connecting portion 31 to the support portion 111.
[0056] In some embodiments, as Figures 1 to 4 As shown, the support portion 111 is provided with a limiting groove 1112 on the side surface thereof obliquely relative to the support surface 1111, and the connecting portion 31 is provided with a limiting protrusion 312 adapted to be clamped into the clamping groove 311, the limiting groove 1112 has an abutment surface 1113, and the limiting protrusion 312 has a second limiting surface 3121 formed on the surface thereof below the abutment surface 1113 along a second direction, the second direction being the support direction of the support portion 111; wherein in the case where the force receiving surface 321 is not subjected to a pushing force, the second limiting surface 3121 is separated from or in abutment with the abutment surface 1113, and in the case where the force receiving surface 321 is subjected to a pushing force along the first direction, the side of the second limiting surface 3121 toward the force receiving surface 321 is in abutment with the abutment surface 1113, and the first limiting surface 3111 and the second limiting surface 3121 clamp the portion of the support portion 111 between the first limiting surface 3111 and the second limiting surface 3121, thereby clamping the connecting portion 31 to the support portion 111.
[0057] In the present embodiment, the side surface of the support portion 111 is provided with a limiting groove 1112, and the connecting portion 31 is provided with a limiting protrusion 312 having a shape and size adapted to the limiting groove 1112, and when the support portion 111 is clamped into the clamping groove 311 of the connecting portion 31, the limiting protrusion 312 is clamped into the limiting groove 1112, and the limiting groove 1112 and the limiting protrusion 312 cooperate to provide additional limiting for the connecting portion 31, and the connecting portion 31 cooperates with the support surface 1111 and the limiting groove 1112 of the support portion 111 through the clamping groove 311 and the limiting protrusion 312, respectively, to form multiple constraint and limiting structures, thereby improving the connection stability and reliability between the connecting portion 31 and the support portion 111.
[0058] On this basis, the limiting groove 1112 has an abutting surface 1113, and the limiting protrusion 312 is arranged on the surface below the abutting surface 1113 along the second direction, i.e., the direction of the supporting direction of the supporting part 111, to form a second limiting surface 3121. When the force receiving surface 321 is not subjected to the pushing force, the second limiting surface 3121 is in a state of separation or adhesion with the abutting surface 1113. At this time, there is no or only a small extrusion and friction force between the abutting surface 1113 and the second limiting surface 3121. When the connecting part 31 is slidingly connected to the supporting part 111, in this case, the connecting part 31 can slide relatively freely on the supporting surface 1111, and the retainer 30 can move smoothly along the first direction of the track 11, so that the retainer adjusts the setting position of the retainer 30 on the supporting part 111 of the track 11 as needed; as Figure 4 shown, when the force receiving surface 321 is subjected to the pushing force F along the first direction, since the force receiving surface 321 is arranged above the supporting part 111 and the limiting protrusion 312 is below the abutting surface 1113, when the connecting part 31 is inclined or has a tendency to be inclined relative to the supporting surface 1111 under the action of the pushing force F, the side of the limiting protrusion 312 towards the force receiving surface 321 abuts against the abutting surface 1113 (approximately at the position indicated by point B in the figure), the limiting protrusion 312 extrudes the supporting part 111, at the same time, the side of the first limiting surface 3111 away from the force receiving surface 321 abuts against the supporting surface 1111, so that the first limiting surface 3111 cooperates with the second limiting surface 3121 to clamp the part of the supporting part 111 between the two limiting surfaces, which further increases the friction force and the restraint strength between the connecting part 31 and the supporting part 111, so that the connecting part 31 can be more reliably clamped on the supporting part 111, effectively preventing accidental sliding of the to-be-moved device.
[0059] In some embodiments, as Figures 1 to 4 shown, the supporting part 111 is provided with a limiting groove 1112 on each of the two sides arranged opposite to each other along the third direction, and the connecting part 31 is provided with a limiting protrusion 312 corresponding to each of the two limiting grooves 1112, and the third direction is perpendicular to the first direction and the second direction.
[0060] The limiting grooves 1112 are arranged on both sides of the supporting part 111 in the width direction, i.e., the third direction, and the connecting part 31 is provided with two limiting protrusions 312 corresponding to the two limiting grooves 1112 for cooperation. After the two limiting protrusions 312 are clamped into the two limiting grooves 1112, the connecting part 31 can be effectively prevented from excessive displacement or shaking in the third direction, thereby further enhancing the stability and reliability of the connection between the connecting part 31 and the supporting part 111.
[0061] In some embodiments, as Figures 1 to 4As shown, the connecting portion 31 comprises a first arm 3102, a second arm 3103 and a connecting arm 3101 connecting the first arm 3102 and the second arm 3103, the connecting arm 3101 is arranged above the support portion 111 along the second direction, the first arm 3102 and the second arm 3103 are arranged apart along the third direction; the first arm 3102, the second arm 3103 and the connecting arm 3101 surround to form a clamping groove 311, the stress receiving portion 32 and the first limiting surface 3111 are arranged on the connecting arm 3101, and the ends of the first arm 3102 and the second arm 3103 away from the connecting arm 3101 are respectively provided with a limiting protrusion 312, and the surface of the limiting protrusion 312 opposite to the first limiting surface 3111 forms a second limiting surface 3121.
[0062] The first arm 3102 and the second arm 3103 are arranged apart along the third direction, i.e. the width direction of the support portion 111, and surround with the connecting arm 3101 to form the clamping groove 311, thereby providing a passing space for the support portion 111. The stress receiving portion 32 and the first limiting surface 3111 are arranged on the connecting arm 3101, and the ends of the first arm 3102 and the second arm 3103 away from the connecting arm 3101 are respectively provided with the limiting protrusion 312, and the surface of the limiting protrusion 312 opposite to the first limiting surface 3111 forms the second limiting surface 3121. The first limiting surface 3111 cooperates with the support surface 1111 on the support portion 111, and the second limiting surface 3121 cooperates with the abutting surface 1113 on the support portion 111, and jointly act when the stress receiving surface 321 is not subjected to the pushing force. The connecting portion 31 is connected with the support portion 111, and the connecting portion 31 is clamped between the support portion 111 through the first arm 3102 and the second arm 3103, so that the stability and reliability of the connection between the connecting portion 31 and the support portion 111 are improved. When the stress receiving surface 321 is subjected to the pushing force, the limiting protrusions 312 arranged on the first arm 3102 and the second arm 3103 cooperate with the connecting arm 3101 to tightly support the support portion 111, so that the connecting portion 31 cannot move relative to the support portion 111, thereby enabling the stopper 30 to effectively stop the accidental sliding of the to-be-moved device.
[0063] In some embodiments, as shown in Figures 1 to 4 The limiting protrusion 312 also has a first guide surface 3122, which is arranged opposite to the second limiting surface 3121, and the first guide surface 3122 is used to guide the support portion 111 to be clamped into the clamping groove 311 along the second direction.
[0064] In the embodiment, the first guide surface 3122 is arranged at the slot opening position of the clamping slot 311 along the second direction, and is used to guide the support part 111 to be clamped into the clamping slot 311 along the second direction, i.e., the supporting direction of the support part 111. The first guide surface 3122 has a certain inclination angle relative to the second direction. When the support part 111 needs to be assembled with the connecting part 31, the first guide surface 3122 can provide a guide path for the support part 111, so that the support part 111 can be more smoothly and accurately clamped into the clamping slot 311, and the installation efficiency of the retreat-stop piece 30 is improved.
[0065] In some embodiments, as shown in Figures 1 to 4 The limiting protrusion 312 is also provided with a second guide surface 3123, which is connected to the second limiting surface 3121 and is arranged to be inclined relative to the first direction. The second guide surface 3123 is used to guide the support part 111 to pass into the clamping slot 311 along the first direction.
[0066] In the embodiment, the second guide surface 3123 is arranged at the slot opening position of the clamping slot 311 along the first direction, and is used to guide the support part 111 to pass into the clamping slot 311 along the first direction, i.e., the length direction of the track 11. The second guide surface 3123 has a certain inclination angle relative to the first direction. When the support part 111 needs to be assembled with the connecting part 31, the second guide surface 3123 can provide a guide for the end of the support part 111, so that the end of the support part 111 can pass into the clamping slot 311 of the connecting part 31, and then the support part 111 is clamped into the clamping slot 311, and the installation efficiency of the retreat-stop piece 30 is improved.
[0067] In specific embodiments, the second limiting surface 3121 has a first side and a second side arranged relative to the first direction. The second guide surface 3123 arranged on one limiting protrusion 312 is connected to the first side of the corresponding second limiting surface 3121, and the second guide surface 3123 arranged on another limiting protrusion 312 is connected to the second side of the corresponding second limiting surface 3121. In this way, along the length direction of the track 11, the two ends of the connecting part 31 form gradually expanding openings by one second guide surface 3123 respectively, so as to facilitate the two ends of the support part 111 to pass in correspondingly.
[0068] In some embodiments, as shown in Figures 1 to 3 At least one of the first arm 3102 and the second arm 3103 is also rotatably connected with a screw rod 33 along the third direction. The knob end of the screw rod 33 is located outside the corresponding first arm 3102 or second arm 3103, and the end of the screw rod of the screw rod 33 protrudes from the slot wall of the clamping slot 311. The screw rod 33 can be rotated to make the end of the screw rod abut against or separate from the slot wall of the corresponding limiting slot 1112.
[0069] In the embodiment, the first arm 3102 is rotatably connected with the screw rod 33 along the third direction, i.e., the width direction of the support portion 111, or the second arm 3103 is rotatably connected with the screw rod 33 along the third direction, i.e., the width direction of the support portion 111, or the first arm 3102 and the second arm 3103 are respectively rotatably connected with the screw rod 33 along the third direction, i.e., the width direction of the support portion 111, the knob end of the screw rod 33 is located outside the corresponding first arm 3102 or second arm 3103, so as to rotate the screw rod 33 by the worker, and the end of the screw rod of the screw rod 33 protrudes from the slot wall of the clamping groove 311, i.e., the end of the screw rod 33 away from the knob end is arranged towards the support portion 111.
[0070] In this way, when the screw rod 33 is rotated and screwed into the corresponding first arm 3102 or second arm 3103, the end of the screw rod can abut against the slot wall of the corresponding limiting groove 1112, i.e., the support portion 111, so as to more stably connect the connecting portion 31 to the support portion 111, or when the screw rod 33 is rotated and screwed out of the corresponding first arm 3102 or second arm 3103, the end of the screw rod can be separated from the slot wall of the corresponding limiting groove 1112, i.e., the support portion 111, so that the connecting portion 31 can be separated from the support portion 111.

[0072] In the embodiment, the carrying and moving device is used to move the device to be maintained to the maintenance position, and in use, the device to be maintained is placed on the support portion 111 of the track 11, and then the device to be moved is driven to move along the length direction of the support portion 111, so as to achieve the purpose.
