Description

Technical Field

[0001] The invention relates to the technical field of tubular reactors, and in particular to a catalyst crushing and suction device for a tubular reactor. Background Art

[0002] The tubular reactor has many parallel and vertical reaction tubes extending from the top tube sheet to the bottom tube sheet. The reaction tubes are usually filled with catalysts. The reactor must be closed periodically, the catalyst must be unloaded, the tubes must be cleaned, and new catalyst must be loaded. During the catalyst unloading process, it is often necessary to use a rod to vibrate upward from the lower opening of the reactor to make the catalyst inside the reaction tube fall off, and then the catalyst residue is sucked out and removed through an external suction device.

[0003] In some reaction processes, the catalyst in the tube has been completely compacted or bridged and cannot be directly extracted. In addition, there are a large number of reaction tubes in the tubular reactor. Especially when the catalyst is severely compacted, manual removal or injection of high-pressure gas or water flow alone cannot quickly loosen the catalyst, resulting in slow progress of the catalyst unloading operation, prolonged operation time, and increased operational risks of the catalyst unloading. Therefore, a catalyst crushing and suction device for a tubular reactor is proposed. Summary of the invention

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention sets a driving assembly so that the electric slider drives the entire driving assembly and the suction assembly to move above the tube bundle array. In conjunction with the circular motion of the traveling trolley, multiple suction assemblies have a maximum range of motion, so that the suction assemblies can be transferred to various areas of the tube bundle array. Then, the lifting hydraulic rod drives the suction assembly to descend into multiple tube bundles through the vertical suspension frame to crush and suction the catalyst residue, thereby realizing automatic cleaning of the tube bundle and greatly improving the cleaning speed of the tubular reactor.

[0018] 2. The present invention sets a suction assembly so that the lifting hydraulic rod drives each flower-shaped slide tube to slide downward inside the flower-shaped slide sleeve, so that the grinding disc moves downward inside the tube bundle to squeeze the catalyst accumulated inside. At the same time, the driving motor drives the transmission gear ring to rotate through the driving gear, and then drives the grinding disc to start rotating through the matching flower-shaped slide sleeve and flower-shaped slide tube, so that the grinding disc spirals down inside the tube bundle to break the compacted and bridged catalyst, so that the texture and structure of the catalyst become loose and easy to be sucked;

[0019] 3. The present invention provides a suction inner tube so that before the grinding disc moves spirally to crush the catalyst, the electromagnetic three-way valve controls the high-pressure water source to be connected to the suction inner tube, and the high-speed water flow is transported to the injection pipe through the suction inner tube and the transfer pipe, so that the high-speed water flow is finally injected into the tube bundle, and the structure of the residual catalyst is destroyed in advance, so that the grinding disc moves more smoothly, and then the crushing of the grinding disc and the impact of the water flow are carried out synchronously, so that the crushed catalyst and the water flow are mixed into a paste-like fluid, which is more convenient for subsequent suction;

[0020] 4. The present invention provides a pressure relief groove so that during the downward pressing process of the grinding disc, the residual gas and the mixed liquid of the catalyst inside the tube bundle will flow upward through the multiple pressure relief grooves on the side of the grinding disc, thereby preventing the gas and liquid inside the tube bundle from being pushed by the grinding disc and generating a large reaction force, thereby affecting the downward process of the grinding disc, and effectively preventing the excessive pressure inside the tube bundle during the cleaning process;

[0021] 5. The present invention provides a side flow channel so that part of the high-speed water flow transported to the inside of the injection pipe will be sprayed into the inside of the tube bundle through the side flow channel on the peripheral side, generating multiple water flows, and spraying to different positions, thereby expanding the damage range of the catalyst. At the same time, with the spiral motion of the grinding disc, the water flow sprayed from the side flow channel will also continuously change the injection direction, thereby reducing the damage dead angle of the catalyst;

[0022] 6. The present invention provides a crushing knife so that in the process of crushing the catalyst, the crushing knife will rotate at high speed with the grinding disc, and then quickly cut and crush the catalyst at the bottom of the grinding disc, so as to avoid the bridging catalyst structure affecting the descent of the grinding disc, and at the same time avoid the incompletely softened catalyst blocking one side of the crushing knife, affecting the ejection of high-speed water flow;

[0023] 7. The present invention provides an arc-shaped monorail and an assembly plate, so that when the circular track is installed inside the reactor, a plurality of arc-shaped monorails are firstly butted against each other, and then the contacting assembly plates are screwed together by fastening bolts, so that two adjacent arc-shaped monorails are assembled together until a plurality of arc-shaped monorails are combined into a complete circular track. The detachable structure makes the installation, storage and transportation of the circular track more convenient;

[0024] 8. The present invention provides guide wheels so that during the travel of the traveling trolley, the guide wheels at the four corners of the top of the traveling trolley will contact the inner wall of the arc-shaped monorail, which guides the travel of the traveling trolley and enables the two traveling trolleys to perform a smooth circular motion around the center of the circular track, thereby improving the balance of the movement of the traveling trolley and ensuring the accuracy of the replacement of the driving assembly and the suction assembly;

[0025] 9. The present invention provides balanced arc-shaped sliding claws, so that when the traveling trolley is installed inside the circular track, the balanced arc-shaped sliding claws on both sides of the guide rail bracket will be buckled on the top of the inner walls on both sides of the arc-shaped monorail. When the traveling trolley moves along the circular track, the balanced arc-shaped sliding claws on both sides will synchronously slide in a circle along the arc-shaped monorail, so that the balanced arc-shaped sliding claws also play a balancing role on the traveling trolley. At the same time, the balanced arc-shaped sliding claws can reduce the load of the two traveling trolleys and share the overall weight of the guide rail bracket, the linear guide rail and other components;

[0026] 10. The present invention sets a laser rangefinder so that after the traveling trolley stops moving, the laser rangefinder emits a ranging light beam toward the inner wall of one side of the arc-shaped monorail. A plurality of evenly distributed positioning protrusions are set on the inner wall of the arc-shaped monorail facing the laser rangefinder. The distribution of the positioning protrusions corresponds to the distribution of the tube bundle array. The ranging results of the laser rangefinder for the inner wall of the arc-shaped monorail and the positioning protrusions are obviously different, thereby ensuring that the stopping position of the traveling trolley is consistent with the position of the tube bundle array, preventing the suction assembly from being misaligned with the tube bundle.

A guide rail bracket 3 is fixedly installed on the top of each traveling trolley 2. The top of the two guide rail brackets 3 is fixedly installed with the same linear guide rail 4. Figure 2As shown, the top drive of the linear guide rail 4 is installed with an electric slider 5, the top of the electric slider 5 is provided with a driving assembly, and one side of the driving assembly is provided with a plurality of evenly distributed suction assemblies; specifically, when the tubular reactor catalyst crushing and suction device is used, the upper end of the tubular reactor is first opened to expose the top of the tube bundle array inside the reactor, and then a circular track 1 is installed at the top of the reactor, and two traveling trolleys 2, a guide rail bracket 3 and a group of linear guide rails 4, and the electric slider 5 are sequentially installed on the circular track 1 from bottom to top, and then the driving assembly and the plurality of suction assemblies are assembled on one side of the electric slider 5, and then the crushing and suction device is started to clean the tube bundle;

[0042] The driving assembly is used to drive the suction assembly to perform spiral motion in each tube bundle of the tubular reactor, such as Figure 4 As shown, the driving assembly includes a horizontal suspension frame 6 fixedly mounted on the top of the electric slider 5, a vertical suspension frame 7 is fixedly mounted on one side of the horizontal suspension frame 6, a loading frame 8 is fixedly mounted on the bottom end of the vertical suspension frame 7, and multiple suction assemblies are arranged on the loading frame 8. A vertically arranged lifting hydraulic rod 13 is fixedly mounted inside the vertical suspension frame 7, a lifting frame 14 is fixedly mounted on the telescopic end of the lifting hydraulic rod 13 facing downward, and a driving motor 15 is fixedly mounted on the bottom end of the vertical suspension frame 7, as shown in FIG. Figure 5 As shown, the driving shaft of the driving motor 15 faces downward and is fixedly sleeved with a driving gear 16, and a plurality of suction components are evenly distributed along the axis of the driving shaft of the driving motor 15, as shown in FIG. Figure 4 As shown, electromagnetic three-way valves 22 having the same number as the suction components are fixedly installed on the top peripheral side of the vertical suspension frame 7. In this embodiment, one end of the electromagnetic three-way valve 22 is connected to a high-pressure water delivery device through a high-pressure water pipe, and the other end is connected to a vacuum suction device through a suction pipeline. Specifically, by setting a driving component, the electric slider 5 drives the entire driving component and the suction component to move above the tube bundle array through the horizontal suspension frame 6 and the vertical suspension frame 7. In conjunction with the circular motion of the traveling trolley 2 and the annular track 1, the multiple suction components can have a maximum range of motion, so that the suction components can be transferred to various areas of the tube bundle array, and then the lifting hydraulic rod 13 drives the suction component to descend into the multiple tube bundles through the vertical suspension frame 7 to crush and suction the catalyst residue, thereby realizing automatic cleaning of the tube bundles and greatly improving the cleaning speed of the tubular reactor.

[0043] The suction assembly is used to break and suck out the residual catalyst that is caked inside the tube bundle. Figure 5 As shown, the suction assembly includes a first suspension bearing 9 fixedly mounted on the loading frame 8, a flower-shaped sliding sleeve 10 is rotatably mounted inside the first suspension bearing 9, a vertically arranged flower-shaped sliding tube 11 is slidably mounted inside the flower-shaped sliding sleeve 10, and a transition tube 12 is fixedly mounted on the top of the flower-shaped sliding tube 11, as shown in FIG. Figure 4As shown, the transition pipe 12 is fixedly mounted on the lifting frame 14. Figure 5 As shown, the top of the flower-shaped sliding sleeve 10 is fixedly sleeved with a transmission gear ring 17, which meshes with the driving gear 16. In this embodiment, the driving gear 16 and the transmission gear ring 17 are both located inside the loading frame 8, so that the loading frame 8 plays a protective role in the meshing transmission of the driving gear 16 and the transmission gear ring 17. The bottom end of the flower-shaped sliding tube 11 is fixedly installed with a grinding disc 18. In this embodiment, the outer diameter of the grinding disc 18 is close to the inner diameter of the tube bundle. Fig. 9 As shown, the interior of the grinding disc 18 is provided with a spray pipe 1801. Figure 8 As shown, a suction inner tube 19 is fixedly installed inside the transition tube 12, and the bottom end of the suction inner tube 19 extends to the inside of the flower-shaped slide tube 11 and is rotatably installed with a transfer tube 21, which is fixedly installed on the top of the grinding disc 18 and is connected to the injection tube 1801. A plurality of second suspension bearings 20 are evenly fixedly installed inside the flower-shaped slide tube 11 from top to bottom, and the suction inner tube 19 is rotatably installed inside the plurality of second suspension bearings 20. The top end of the suction inner tube 19 at the same location is fixedly connected to one end of the electromagnetic three-way valve 22. In this embodiment, the number and position of the suction components and the specific shape of the loading frame 8 are based on the actual arrangement of the tube bundles of the tubular reactor, so that the suction components can adapt to the tube bundle array to the maximum extent and reduce the dead angle area. In this embodiment, four suction components are described as a group, as shown in FIG. Figure 2 and Figure 5As shown, four flower-shaped slide tubes 11 are uniformly surrounded by the circumference of the driving motor 15, and four transmission gear rings 17 are all meshed with the driving gear 16, and the four flower-shaped slide tubes 11 are synchronously driven by one driving motor 15; specifically, by arranging a suction assembly, when multiple flower-shaped slide tubes 11 move to the top of the tube bundle to be cleaned, the lifting hydraulic rod 13 drives each flower-shaped slide tube 11 to slide downward inside the flower-shaped slide sleeve 10 through the vertical suspension frame 7 and the loading frame 8, so that the grinding disc 18 moves downward inside the tube bundle to squeeze the catalyst accumulated inside, and at the same time, the driving motor 15 drives the transmission gear ring 17 to rotate through the driving gear 16, and then drives the grinding disc 18 to start rotating through the matching flower-shaped slide sleeve 10 and the flower-shaped slide tube 11, so that the grinding disc 18 spirals down inside the tube bundle, breaks the compacted and bridged catalyst, and makes the texture and structure of the catalyst become The catalyst is loose and easy to be sucked. By setting the inner suction pipe 19, before the grinding disc 18 spirally moves to crush the catalyst, the electromagnetic three-way valve 22 will control the high-pressure water source to be connected to the inner suction pipe 19, and the high-speed water flow is transported to the injection pipe 1801 through the inner suction pipe 19 and the transfer pipe 21, so that the high-speed water flow is finally sprayed inside the tube bundle, and the structure of the residual catalyst is destroyed in advance, so that the movement of the grinding disc 18 is smoother. After that, the crushing of the grinding disc 18 and the impact of the water flow are carried out simultaneously, so that the crushed catalyst is mixed with the water flow into a paste-like fluid, which is more convenient for subsequent suction. After the crushing process is completed, the electromagnetic three-way valve 22 controls the vacuum suction equipment to be connected to the inner suction pipe 19, and the vacuum suction equipment sucks the catalyst mixture in a fluid state through the inner suction pipe 19, the transfer pipe 21 and the injection pipe 1801 until the process is completed, and the grinding disc 18 is reset to wait for the next tube bundle to be processed.

[0044] like Fig. 9 As shown, a plurality of pressure relief grooves 1802 are uniformly distributed along the axis of the grinding disc 18 on the circumferential side of the grinding disc 18; specifically, by providing the pressure relief grooves 1802, during the downward pressing process of the grinding disc 18, the residual gas and catalyst mixture inside the tube bundle will flow upward through the plurality of pressure relief grooves 1802 on the circumferential side of the grinding disc 18, thereby preventing the gas and liquid inside the tube bundle from being pushed by the grinding disc 18 and generating a large reaction force, affecting the descending process of the grinding disc 18, and effectively preventing excessive pressure inside the tube bundle during the cleaning process.

[0045] like Fig. 9As shown, a plurality of side channels 1803 evenly distributed along the axis of the injection pipe 1801 are provided at the bottom of the grinding disc 18, and the plurality of side channels 1803 are all connected to the injection pipe 1801; specifically, by providing the side channels 1803, part of the high-speed water flow delivered to the inside of the injection pipe 1801 will be injected into the inside of the tube bundle through the side channels 1803 on the peripheral side, thereby generating multiple streams of water, and injected to different positions, thereby expanding the scope of damage to the catalyst; at the same time, with the spiral motion of the grinding disc 18, the water flow ejected from the side channels 1803 will also continuously change the injection direction, thereby reducing the dead angles of damage to the catalyst.

[0046] like Fig. 9 As shown, a plurality of evenly distributed crushing knives 1804 are fixedly installed at the bottom of the grinding disc 18, and the plurality of crushing knives 1804 are staggered with the plurality of side flow channels 1803; specifically, by arranging the crushing knives 1804, in the process of crushing the catalyst, the crushing knives 1804 will rotate at a high speed along with the grinding disc 18, and then quickly cut off and crush the catalyst at the bottom of the grinding disc 18, so as to avoid the bridging catalyst structure affecting the descent of the grinding disc 18, and at the same time avoid the incompletely softened catalyst from being blocked on one side of the crushing knife 1804, affecting the ejection of high-speed water flow.

[0047] like Figure 6 As shown, the annular track 1 includes a plurality of evenly distributed arc-shaped monorails 101, and mounting plates 102 are fixedly mounted on the side walls at both ends of the arc-shaped monorails 101; specifically, by arranging the arc-shaped monorails 101 and the mounting plates 102, when the annular track 1 is installed inside the reactor, the plurality of arc-shaped monorails 101 are firstly butted against each other, and then the contacting mounting plates 102 are screwed together by fastening bolts, so that two adjacent arc-shaped monorails 101 are assembled together, until the plurality of arc-shaped monorails 101 are combined into a complete annular track 1, and the detachable structure makes the installation, storage and transportation of the annular track 1 more convenient.

[0048] like Figure 3 As shown, guide wheels 23 are rotatably installed at the four corners of the top of the traveling trolley 2, and the four guide wheels 23 are in contact with the inner wall of the arc-shaped monorail 101; specifically, by setting the guide wheels 23, during the movement of the traveling trolley 2, the guide wheels 23 at the four corners of the top of the traveling trolley 2 will contact the inner wall of the arc-shaped monorail 101, which guides the movement of the traveling trolley 2, and makes the two traveling trolleys 2 make smooth circular motion around the center position of the annular track 1, thereby improving the balance of the movement of the traveling trolley 2 and ensuring the accuracy of the drive assembly and the suction assembly when they are replaced.

[0049] like Figure 3As shown, balancing arc sliding claws 24 are fixedly installed on both sides of the guide rail bracket 3, and the balancing arc sliding claws 24 are compatible with the arc monorail 101; specifically, by setting the balancing arc sliding claws 24, when the traveling trolley 2 is installed inside the circular track 1, the balancing arc sliding claws 24 on both sides of the guide rail bracket 3 will be buckled on the top of the inner walls on both sides of the arc monorail 101. In the process of the traveling trolley 2 moving along the circular track 1, the balancing arc sliding claws 24 on both sides will synchronously slide in a circle along the arc monorail 101, so that the balancing arc sliding claws 24 also balance the traveling trolley 2. At the same time, the balancing arc sliding claws 24 can reduce the load of the two traveling trolleys 2 and share the overall weight of the guide rail bracket 3, the linear guide 4 and other components.

[0050] like Figure 3 As shown, a laser rangefinder 25 is fixedly installed on one side of the traveling vehicle 2. Figure 6 As shown, a plurality of evenly distributed positioning protrusions 103 are fixedly installed on the inner wall of the arc-shaped monorail 101, and the positions of the positioning protrusions 103 correspond to the positions of the laser rangefinder 25; specifically, by setting the laser rangefinder 25, after the traveling trolley 2 stops moving, the laser rangefinder 25 on one side of the traveling trolley 2 will be started to emit a distance measuring beam toward the inner wall of one side of the arc-shaped monorail 101, and a plurality of evenly distributed positioning protrusions 103 are arranged on the inner wall of the arc-shaped monorail 101 facing the laser rangefinder 25, and the distribution of the positioning protrusions 103 corresponds to the distribution of the tube bundle array. The distance measurement results of the laser rangefinder 25 on the inner wall of the arc-shaped monorail 101 and on the positioning protrusions 103 will be obviously different, thereby ensuring that the stopping position of the traveling trolley 2 will be consistent with the position of the tube bundle array, and preventing the suction component from being misaligned with the tube bundle.

[0051] In summary: when the catalyst crushing and suction device for the tubular reactor is in use, the upper end of the tubular reactor is first opened to expose the top of the tube bundle array inside the reactor, and then a circular track 1 is installed at the top of the reactor, and two traveling trolleys 2, a guide rail bracket 3 and a group of linear guide rails 4, and an electric slider 5 are installed on the circular track 1 from bottom to top, and then the drive assembly and multiple suction assemblies are assembled on one side of the electric slider 5, and then the crushing and suction device is started to clean the tube bundle. By setting the drive assembly, the electric slider 5 will drive the entire drive assembly and the suction assembly to move above the tube bundle array through the horizontal suspension frame 6 and the vertical suspension frame 7, and cooperate with the circular motion of the traveling trolley 2 and the circular track 1, so that the multiple suction assemblies can be The suction assembly has a maximum range of motion, so that the suction assembly can be transferred to various areas of the tube bundle array, and then the lifting hydraulic rod 13 drives the suction assembly to descend into multiple tube bundles through the vertical suspension frame 7 to crush and suction the catalyst residue, thereby realizing the automatic cleaning of the tube bundle and greatly improving the cleaning speed of the tubular reactor. By setting the suction assembly, when multiple flower-shaped slide tubes 11 move to the top of the tube bundle to be cleaned, the lifting hydraulic rod 13 drives each flower-shaped slide tube 11 to slide downward inside the flower-shaped slide sleeve 10 through the vertical suspension frame 7 and the loading frame 8, so that the grinding disc 18 moves downward inside the tube bundle to squeeze the catalyst accumulated inside, and at the same time, the driving motor 15 drives the transmission gear ring 17 to rotate through the driving gear 16, and then through the corresponding The matched flower-shaped sliding sleeve 10 and flower-shaped sliding tube 11 drive the grinding disc 18 to start rotating, so that the grinding disc 18 spirally descends inside the tube bundle, breaks the compacted and bridged catalyst, and makes the texture and structure of the catalyst loose and easy to be sucked. By setting the suction inner tube 19, before the grinding disc 18 spirally moves to break the catalyst, the electromagnetic three-way valve 22 will control the high-pressure water source to be connected with the suction inner tube 19, and the high-speed water flow is transported to the injection pipe 1801 through the suction inner tube 19 and the transfer tube 21, so that the high-speed water flow is finally sprayed inside the tube bundle, and the structure of the residual catalyst is destroyed in advance, so that the grinding disc 18 moves more smoothly, and then the crushing of the grinding disc 18 and the impact of the water flow are carried out synchronously, so that the crushed catalyst and the water flow are mixed into a paste-like fluid. It is more convenient for subsequent suction. After the crushing process is completed, the electromagnetic three-way valve 22 controls the vacuum suction equipment to be connected with the suction inner tube 19. The vacuum suction equipment sucks the catalyst mixture in a fluid state through the suction inner tube 19, the transfer tube 21 and the injection tube 1801 until the process is completed. The grinding disc 18 is reset and waits for the next tube bundle to be processed. By setting the pressure relief groove 1802, during the downward pressure of the grinding disc 18, the residual gas and the catalyst mixture inside the tube bundle will flow upward through the multiple pressure relief grooves 1802 on the side of the grinding disc 18, so as to avoid the gas and liquid inside the tube bundle being pushed by the grinding disc 18 and generating a large reaction force, affecting the descending process of the grinding disc 18, and effectively preventing the excessive pressure inside the tube bundle during the cleaning process.By setting the side channel 1803, part of the high-speed water flow transported to the inside of the injection pipe 1801 will be sprayed into the inside of the tube bundle through the side channel 1803 on the side, generating multiple streams of water, and spraying them to different positions, thereby expanding the scope of damage to the catalyst. At the same time, with the spiral motion of the grinding disc 18, the water flow sprayed from the side channel 1803 will also continuously change the injection direction, thereby reducing the dead angle of damage to the catalyst. By setting the crushing knife 1804, in the process of crushing the catalyst, the crushing knife 1804 will rotate at high speed with the grinding disc 18, thereby quickly cutting off and crushing the catalyst at the bottom of the grinding disc 18, thereby avoiding the bridging catalyst structure from affecting the descent of the grinding disc 18, and at the same time avoiding incomplete The fully softened catalyst is sealed on one side of the crushing knife 1804, affecting the ejection of the high-speed water flow. By setting the arc-shaped monorail 101 and the assembly plate 102, when the circular track 1 is installed inside the reactor, the multiple arc-shaped monorails 101 are first docked with each other, and then the contacting assembly plates 102 are screwed together by fastening bolts, so that the two adjacent arc-shaped monorails 101 are assembled together until the multiple arc-shaped monorails 101 are combined into a complete circular track 1. The detachable structure makes the installation and storage and transportation of the circular track 1 more convenient. By setting the guide wheels 23, during the travel of the traveling trolley 2, the guide wheels 23 at the four corners of the top of the traveling trolley 2 will contact the inner wall of the arc-shaped monorail 101, which is conducive to the travel of the traveling trolley 2. The movement of the two traveling trolleys 2 plays a guiding role, so that the two traveling trolleys 2 make a smooth circular motion around the center position of the circular track 1, which improves the balance of the movement of the traveling trolley 2 and ensures the accuracy of the drive component and the suction component when they are replaced. By setting the balancing arc sliding claws 24, when the traveling trolley 2 is installed inside the circular track 1, the balancing arc sliding claws 24 on both sides of the guide rail bracket 3 will be buckled on the top of the inner walls on both sides of the curved monorail 101. In the process of the traveling trolley 2 moving along the circular track 1, the balancing arc sliding claws 24 on both sides will synchronously slide in a circle along the curved monorail 101, so that the balancing arc sliding claws 24 also balance the traveling trolley 2. At the same time, the balancing arc sliding claws 24 can reduce the two The load of the traveling trolley 2 is shared, and the overall weight of the guide rail bracket 3 and the linear guide rail 4 and other components are shared. By setting the laser rangefinder 25, after the traveling trolley 2 stops moving, the laser rangefinder 25 on one side of the traveling trolley 2 will start, and emit a distance measurement beam toward the inner wall of one side of the arc monorail 101. A plurality of evenly distributed positioning protrusions 103 are arranged on the inner wall of the arc monorail 101 facing the laser rangefinder 25. The distribution of the positioning protrusions 103 corresponds to the distribution of the tube bundle array. The distance measurement results of the laser rangefinder 25 on the inner wall of the arc monorail 101 and on the positioning protrusions 103 will be significantly different, thereby ensuring that the stopping position of the traveling trolley 2 will be consistent with the position of the tube bundle array, and preventing the suction assembly from being misaligned with the tube bundle.
