Abstract
Description
Technical Field
[0001] This invention belongs to the field of overhead crane unit technology, specifically a stacking overhead crane for graphite crucibles. Background Technology
[0002] Graphite crucibles, also known as copper smelting crucibles or copper melting crucibles, are a type of crucible made from graphite, clay, silica, and pyrite. Graphite crucibles are mainly used for smelting non-ferrous metals and their alloys, such as copper, brass, gold, silver, zinc, and lead. Made primarily of natural flake graphite and using malleable refractory clay or carbonaceous material as a binder, graphite crucibles are characterized by high temperature resistance, strong thermal conductivity, good corrosion resistance, and long service life. For large-volume graphite crucibles, overhead cranes are typically used for lifting and stacking, employing hooks to lift and transport the crucibles before stacking them at the designated location.
[0003] Existing graphite crucible stacking cranes typically utilize a crane unit with rotating wheels positioned on a track. An active motor drives these wheels, causing the crane unit to move and thus lift and stack the graphite crucibles. However, during this movement, the contact pressure between the metal rotating wheels and the metal track, coupled with strong friction, results in significant noise. This repetitive lifting and stacking of graphite crucibles by the crane unit leads to a poor working environment and unsatisfactory performance.
[0004] Furthermore, in the existing graphite crucible stacking crane, during operation, as the crane moves along the track, when it reaches the limit position, the buffer limit seat usually contacts the baffle at the limit position to stop the crane and avoid collisions. However, in actual operation, the crane operator manually stops the crane after discovering the buffer seat contact, which takes a certain amount of time. This means that in the short period before the actual stop, the crane still tends to move forward, which can easily lead to brief and repeated collisions, resulting in a relatively slow actual stopping speed. Summary of the Invention
[0005] The purpose of this invention is to provide a special stacking crane for graphite crucibles to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a graphite crucible stacking crane, comprising a body and a track assembly, wherein a driver's cab is fixedly mounted on the bottom surface of the body, a winding mechanism is provided on the top surface of the body, a rotating shaft is movably mounted inside the body, a connecting shaft is fixedly connected to the end face of the rotating shaft, a rotating wheel and a first gear are respectively fixedly sleeved on the outer surface of the connecting shaft, a fixing frame is fixedly mounted on the end face of the body, a first bearing is movably mounted on the end face of the body, a first shaft is fixedly sleeved on the outer surface of the first bearing, and the first shaft... The outer surface of the frame is fixedly fitted with a No. 2 gear and a spiral blade. A connecting plate is fixedly fitted on the top surface of the frame. A conveying sleeve is fixedly connected to the bottom surface of the connecting plate. The conveying sleeve is fitted onto the outside of the spiral blade. A connecting cover is fixedly connected to the end face of the conveying sleeve. A curved pipe is fixedly connected to the side of the connecting cover. A distribution sleeve is fixedly connected to the top surface of the frame. The distribution sleeve is fixedly connected to the curved pipe. An oil tank is fixedly connected to the top surface of the connecting plate. An oil outlet pipe is fixedly connected to the bottom surface of the distribution sleeve. A nozzle is fixedly fitted to the lower end of the oil outlet pipe.
[0007] First embodiment: as follows Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and 7 As shown, when the machine moves, the internal power mechanism drives the rotating shaft to rotate, which in turn drives the connecting shaft to rotate, causing the rotating wheel to move along the track assembly. At the same time, the first gear sleeved on the connecting shaft rotates, causing the second gear meshing with the first gear to rotate. As the second gear rotates, the first shaft, which is fixedly sleeved with the second gear, rotates, causing the first shaft to drive the sleeved spiral blades to rotate. As the spiral blades rotate, the lubricating oil in the oil tank flows along the connecting plate to the spiral blades, and is squeezed into the curved tube by the rotating spiral blades. As the lubricating oil is continuously squeezed in, it enters the distribution sleeve along the curved tube and flows into the interior of the oil outlet pipe. Atomized lubricating oil is sprayed out from the nozzles below the oil outlet pipe. As the rotating wheel rotates, the atomized lubricating oil sprayed from the nozzles covers the outside of the rotating wheel, and a layer of lubricating oil adheres to the top surface of the track assembly, reducing the noise of the rotating wheel rolling forward.
[0008] First, a connecting shaft is fixedly installed on the end face of the rotating shaft, and a rotating wheel and a No. 1 gear are fixedly sleeved on the outer surface of the connecting shaft. A No. 1 shaft is movably installed on the end face of the machine body, and a No. 2 gear on the outer surface of the No. 1 shaft meshes with the No. 1 gear. This allows the No. 1 shaft to rotate when the crane unit moves. The rotation of the No. 1 shaft, in conjunction with the sleeved spiral blades, forces the lubricating oil in the oil tank to be pumped into the distribution sleeve. The lubricating oil is then atomized and sprayed out through the oil outlet pipe and nozzle on the bottom surface of the distribution sleeve. This atomized lubricating oil coats the rotating wheel and coats the track assembly with a layer of lubricating oil. The atomized lubricating oil surrounding the rotating wheel absorbs outward-spreading noise waves, thus reducing the actual noise level. Furthermore, the lubricating oil layer on the track assembly replaces direct contact between the rotating wheel and the fixed track assembly, reducing the sound wave transmission speed and improving attenuation, thereby achieving noise reduction.
[0009] Preferably, the top surface of the conveying sleeve is provided with a top groove, the upper end of the top groove is connected to the connecting plate, and the end face of the conveying sleeve is provided with an outlet groove. The top groove allows lubricating oil to fall from the connecting plate into the spiral blades, and the outlet groove allows the squeezed lubricating oil to enter the connecting cover, thereby realizing the conveying and transfer of lubricating oil.
[0010] Preferably, a blower mechanism is movably mounted on the end face of the machine body, and a mounting plate is fixedly connected to the end face of the fixed frame. The blower mechanism is fixedly connected to the mounting plate, and a mounting tube is fixedly connected to the side of the mounting plate. A spring is provided inside the mounting tube, and the inner end of the spring is fixedly connected to the mounting plate. By utilizing the elasticity of the spring, buffer protection at extreme positions is achieved, and the blower mechanism is activated by the connecting shaft and the first gear to blow air and clean the track plate by blowing out air volume.
[0011] Preferably, the bottom surface of the mounting pipe is fixedly connected to an air outlet pipe, and the inside of the mounting plate is provided with a curved hole. The outer end of the curved hole is connected to the mounting pipe. The air volume in the connecting pipe is guided to the mounting pipe through the curved hole and blown towards the track plate in conjunction with the air outlet pipe.
[0012] Preferably, a movable rod is movably sleeved on the inner surface of the mounting tube, the inner end face of the movable rod is fixedly connected to a spring, a buffer seat is fixedly connected to the outer end face of the movable rod, a cleaning frame is fixedly connected to the bottom surface of the buffer seat, and the cleaning frame is movably sleeved with the track assembly. By using the cleaning frame to push away obstacles during movement, stable movement is ensured.
[0013] Preferably, the track assembly includes a base plate, a track plate, and an inner groove. The track plate is fixedly connected to the top surface of the base plate, and the inner groove is opened on the top surface of the base plate. The inner groove is symmetrically distributed on both sides of the track plate. By using the inner groove to store the lubricating oil that gradually slides down, centralized collection is achieved, which facilitates subsequent recycling and other operations.
[0014] Preferably, the blower mechanism includes a second bearing, a second shaft, a third gear, blades, a sealing tube, a top plate, and a connecting tube. The second shaft is movably mounted in the inner surface of the second bearing. The third gear and blades are both fixedly sleeved on the outer surface of the second shaft. The sealing tube is sleeved on the outer side of the blades. The top plate is fixedly connected to the top surface of the sealing tube, and the top surface of the top plate is fixedly connected to the fixed frame. The connecting tube is fixedly connected to the end face of the sealing tube, and the outer end of the connecting tube is fixedly connected to the mounting plate and communicates with the curved hole. By utilizing the meshing connection between the third gear and the first gear, and cooperating with the rotation of the connecting shaft, the second shaft is rotated, thereby driving the blades to rotate and forming axial airflow.
[0015] Preferably, the end face of the machine body is provided with a mounting groove, and the number of mounting grooves is four. The four mounting grooves are divided into two groups of two, and are divided into left and right groups. The inner surfaces of the two groups of mounting grooves are respectively fixedly sleeved with bearing No. 1 and bearing No. 2. The mounting grooves are used to complete the installation of bearing No. 1 and bearing No. 2. The end face of the machine body has two different groups of mounting grooves.
[0016] Preferably, the track plate is located below the air outlet duct, and the outer surface of the track plate is movably connected to the cleaning frame. By setting the positions of the air outlet duct and the cleaning frame, the track assembly is guaranteed to have a good dust removal and obstacle removal function.
[0017] Second embodiment: as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 9 and Figure 10When the overhead crane unit is moved, the rotation of the shaft causes the connecting shaft to rotate coaxially, and the first gear on the outer surface of the connecting shaft rotates. This rotation of the first gear drives the third gear in the blower mechanism to rotate, which in turn drives the second shaft to rotate. The rotation of the second shaft causes the blades fixed to it to rotate, creating axial airflow. This axial airflow in the sealed pipe enters the curved hole in the mounting plate through the connecting pipe. The airflow in the curved hole enters the mounting pipe and is distributed along the outlet pipe below the mounting pipe. The airflow discharged from the outlet pipe blows along the top surface of the track plate, causing the track plate... Dust and impurities are blown away, and as the overhead crane unit moves, the cleaning frame on the bottom of the buffer seat pushes away solid obstacles on the track assembly. When the overhead crane unit reaches the limit position, the buffer seat contacts the limit baffle and drives the movable rod to compress the spring, causing the spring in the mounting tube to compress. At the same time, the movable rod moves along the inner wall of the mounting tube and seals the top of the air outlet pipe, and the mounting tube remains sealed. Before the internal power mechanism of the machine completely stops, the blades continue to rotate with the No. 2 shaft and the connecting shaft, causing the air pressure inside the mounting tube to rise rapidly. Under the action of the internal air pressure, the blades stop rotating, forcing the No. 2 shaft and the connecting shaft to stop. The overhead crane unit stops quickly, and the operator performs the shutdown operation.
[0018] Firstly, by adding a blower mechanism to the end face of the machine body, the rotation of the connecting shaft, in conjunction with the rotation of the first gear on the connecting shaft, enables the rotation of the third gear in the blower mechanism. This causes the third gear to drive the second shaft to rotate, and together with the blades fixedly connected to the second shaft, an axial flow is formed. The generated air volume is then introduced into the installation pipe through the curved hole via a connecting pipe, and together with the air outlet pipe, it blows air downwards onto the track plate. The airflow effect cleans the dust and impurities on the track plate, and the subsequent atomized lubricating oil adheres to the track plate, providing good lubrication when the rotating wheel passes over it. This prevents the accumulation of impurities and increases friction, improves the actual movement quality of the rotating wheel, enhances movement stability, and results in good performance.
[0019] Furthermore, by utilizing the meshing of gear number one on the connecting shaft and gear number three on the second shaft, the second shaft is rotated, forming an axial flow with the blades. This airflow is then introduced into the installation pipe through the connecting pipe. When the buffer seat experiences a buffer collision, the moving rod is immediately compressed and the installation pipe is sealed. This allows the blades to continue rotating, creating a high-pressure space within the installation pipe. The internal high-pressure reaction force is applied to the blades, causing them and the second shaft to stall, thus stopping the rotating shaft and connecting shaft. This rapid automatic stop avoids repeated movement and collisions of the overhead crane unit within the operator's reaction time, resulting in excellent performance.
[0020] The beneficial effects of this invention are as follows:
[0021] 1. This invention involves fixing a connecting shaft to the end face of a rotating shaft, and fixing a rotating wheel and a first gear to the outer surface of the connecting shaft. A first shaft is movably installed on the end face of the machine body, and a second gear on the outer surface of the first shaft meshes with the first gear. This allows the first shaft to rotate when the crane unit moves. The rotation of the first shaft, combined with the sleeved spiral blades, forces lubricating oil from the oil tank into a distribution sleeve. The lubricating oil is atomized and sprayed out through an oil outlet pipe and nozzle on the bottom surface of the distribution sleeve. This atomized lubricating oil surrounds the rotating wheel and adheres a layer of lubricating oil to the track assembly. The atomized lubricating oil surrounding the rotating wheel absorbs outward-spreading noise waves, reducing the actual noise level. Furthermore, the lubricating oil layer on the track assembly replaces direct contact between the rotating wheel and the fixed track assembly, reducing the sound wave transmission speed and improving attenuation, thus achieving noise reduction.
[0022] 2. This invention adds a blower mechanism to the end face of the machine body. By rotating the connecting shaft, the first gear on the connecting shaft rotates, which in turn rotates the third gear in the blower mechanism. This causes the third gear to drive the second shaft to rotate, and together with the blades fixedly connected to the second shaft, an axial flow is formed. The generated air volume is introduced into the mounting pipe through the curved hole via the connecting pipe, and together with the air outlet pipe, it blows air downwards onto the track plate. The air force cleans the dust and impurities on the track plate, and the subsequent atomized lubricating oil adheres to the track plate, so that the rotating wheel has a good lubrication effect when it passes over it, avoiding the accumulation of impurities and increasing friction, improving the actual moving quality of the rotating wheel, improving moving stability, and having a good performance.
[0023] 3. This invention utilizes the meshing of gear number one on the connecting shaft and gear number three on the second shaft to achieve the rotation of the second shaft. This, combined with the blades, forms axial airflow, which is then introduced into the installation pipe through the connecting pipe. When the buffer seat experiences a buffer collision, it immediately compresses the movable rod and seals the installation pipe. This allows the blades to continue rotating, creating a high-pressure space within the installation pipe. The internal high-pressure reaction force is applied to the blades, causing them and the second shaft to stall, thus stopping the rotating shaft and connecting shaft. This rapid automatic stop avoids repeated movement and collisions of the overhead crane unit within the operator's reaction time, resulting in excellent performance. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0036] like Figures 1 to 10As shown, this embodiment of the invention provides a special stacking crane for graphite crucibles, including a body 1 and a track assembly 4. A driver's cab 2 is fixedly installed on the bottom surface of the body 1, and a winding mechanism 3 is provided on the top surface of the body 1. A rotating shaft 5 is movably installed inside the body 1, and a connecting shaft 6 is fixedly connected to the end face of the rotating shaft 5. A rotating wheel 7 and a first gear 8 are respectively fixedly sleeved on the outer surface of the connecting shaft 6. A fixing frame 9 is fixedly installed on the end face of the body 1, and a first bearing 10 is movably installed on the end face of the body 1. A first shaft 11 is fixedly sleeved on the outer surface of the first bearing 10, and two... Gear 12 and helical blade 13, a connecting plate 19 is fixedly sleeved on the top surface of the fixed frame 9, a conveying sleeve 14 is fixedly connected to the bottom surface of the connecting plate 19, the conveying sleeve 14 is sleeved on the outside of the helical blade 13, a connecting cover 17 is fixedly connected to the end face of the conveying sleeve 14, a curved pipe 18 is fixedly connected to the side of the connecting cover 17, a distribution sleeve 21 is fixedly connected to the top surface of the fixed frame 9, the distribution sleeve 21 is fixedly connected to the curved pipe 18, an oil tank 20 is fixedly connected to the top surface of the connecting plate 19, an oil outlet pipe 22 is fixedly connected to the bottom surface of the distribution sleeve 21, and a nozzle 23 is fixedly sleeved at the lower end of the oil outlet pipe 22.
[0037] First embodiment: as follows Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and 7 As shown, when the machine body 1 moves, the internal power mechanism of the machine body 1 drives the rotating shaft 5 to rotate, which in turn drives the connecting shaft 6 to rotate, causing the rotating wheel 7 to move along the track assembly 4. At the same time, the first gear 8 sleeved on the connecting shaft 6 rotates, which in turn causes the second gear 12 meshing with the first gear 8 to rotate. As the second gear 12 rotates, the first shaft 11, which is fixedly sleeved with the second gear 12, rotates, which in turn drives the sleeved spiral blade 13 to rotate. As the spiral blade 13 rotates, the oil tank 2... The lubricating oil in the 0 flows along the connecting plate 19 to the spiral blade 13, and is squeezed into the curved tube 18 by the rotating spiral blade 13. As the lubricating oil is continuously squeezed in, it enters the distribution sleeve 21 along the curved tube 18 and flows into the interior of the oil outlet pipe 22. The nozzle 23 sprays atomized lubricating oil along the oil outlet pipe 22. As the rotating wheel 7 rotates, the atomized lubricating oil sprayed by the nozzle 23 covers the outside of the rotating wheel 7, and a layer of lubricating oil adheres to the top surface of the track assembly 4, reducing the noise of the rotating wheel 7 rolling forward.
[0038] First, a connecting shaft 6 is fixedly installed on the end face of the rotating shaft 5, and a rotating wheel 7 and a first gear 8 are fixedly sleeved on the outer surface of the connecting shaft 6. A first shaft 11 is movably installed on the end face of the machine body 1, and a second gear 12 on the outer surface of the first shaft 11 meshes with the first gear 8. This allows the first shaft 11 to rotate when the crane unit moves. The rotation of the first shaft 11, in conjunction with the sleeved spiral blades 13, forces the lubricating oil in the oil tank 20 into the distribution sleeve 21. This process is then further facilitated by utilizing… The oil outlet pipe 22 and nozzle 23 on the bottom surface of the distribution sleeve 21 atomize and spray the lubricating oil, thereby covering the rotating wheel 7 with the sprayed atomized lubricating oil and attaching a layer of lubricating oil to the track assembly 4. The atomized lubricating oil surrounding the outside of the rotating wheel 7 absorbs the outwardly diffused noise waves, thereby reducing the actual noise level. In addition, the lubricating oil layer attached to the track assembly 4 replaces the direct contact between the rotating wheel 7 and the fixed track assembly 4, reducing the sound wave transmission speed and improving the attenuation effect, thereby achieving the effect of reducing noise.
[0039] The top surface of the conveying sleeve 14 is provided with a top groove 15, the upper end of which is connected to the connecting plate 19. The end face of the conveying sleeve 14 is provided with an outlet groove 16. The top groove 15 allows lubricating oil to fall from the connecting plate 19 into the spiral blade 13, and the outlet groove 16 allows the squeezed lubricating oil to enter the connecting cover 17, thereby realizing the conveying and transfer of lubricating oil.
[0040] Among them, a blower mechanism 24 is movably installed on the end face of the body 1, and a mounting plate 25 is fixedly connected to the end face of the fixed frame 9. The blower mechanism 24 is fixedly connected to the mounting plate 25. A mounting tube 26 is fixedly connected to the side of the mounting plate 25. A spring 27 is provided inside the mounting tube 26. The inner end of the spring 27 is fixedly connected to the mounting plate 25. By utilizing the elasticity of the spring 27, buffer protection at the extreme position is achieved. The blower mechanism 24 is blown by the connecting shaft 6 and the first gear 8. The air volume blown out is used to clean the track plate 42.
[0041] The bottom surface of the mounting pipe 26 is fixedly connected to the air outlet pipe 28. The mounting plate 25 has a curved hole 32 inside. The outer end of the curved hole 32 is connected to the mounting pipe 26. The air volume in the connecting pipe 247 is guided to the mounting pipe 26 through the curved hole 32 and blown towards the track plate 42 in conjunction with the air outlet pipe 28.
[0042] Among them, the inner surface of the mounting tube 26 is movably sleeved with a movable rod 29, the inner end face of the movable rod 29 is fixedly connected to the spring 27, the outer end face of the movable rod 29 is fixedly connected to a buffer seat 30, the bottom surface of the buffer seat 30 is fixedly connected to a cleaning frame 31, the cleaning frame 31 is movably sleeved with the track assembly 4, and the cleaning frame 31 pushes away obstacles during the movement to ensure stable movement.
[0043] The track assembly 4 includes a base plate 41, a track plate 42, and an inner groove 43. The track plate 42 is fixedly connected to the top surface of the base plate 41, and the inner groove 43 is opened on the top surface of the base plate 41. The inner groove 43 is symmetrically distributed on both sides of the track plate 42. By using the inner groove 43 to store the lubricating oil that gradually slides down, it can be collected in a centralized manner, which facilitates subsequent recycling and other operations.
[0044] The blower mechanism 24 includes a second bearing 241, a second shaft 242, a third gear 243, blades 244, a sealing tube 245, a top plate 246, and a connecting tube 247. The second shaft 242 is movably installed in the inner surface of the second bearing 241. The third gear 243 and blades 244 are both fixedly sleeved on the outer surface of the second shaft 242. The sealing tube 245 is sleeved on the outer side of the blades 244. The top plate 246 is fixedly connected to the top surface of the sealing tube 245. The top surface of the top plate 246 is fixedly connected to the fixed frame 9. The connecting tube 247 is fixedly connected to the end face of the sealing tube 245. The outer end of the connecting tube 247 is fixedly connected to the mounting plate 25 and communicates with the curved hole 32. By using the meshing connection between the third gear 243 and the first gear 8, and cooperating with the rotation of the connecting shaft 6, the second shaft 242 is rotated, thereby driving the blades 244 to rotate and forming axial airflow.
[0045] The end face of the body 1 is provided with four mounting slots 33. The four mounting slots 33 are divided into two groups of two, and are divided into left and right groups. The inner surfaces of the two groups of mounting slots 33 are fixedly sleeved with the first bearing 10 and the second bearing 241 respectively. The first bearing 10 and the second bearing 241 are installed by using the mounting slots 33. The end face of the body 1 has two different groups of mounting slots 33.
[0046] The track plate 42 is located below the air outlet duct 28. The outer surface of the track plate 42 is movably connected to the cleaning frame 31. By setting the positions of the air outlet duct 28 and the cleaning frame 31, the track assembly 4 is guaranteed to have a good dust removal and obstacle removal function.
[0047] Second embodiment: as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 9 and Figure 10When the crane unit is moved, the rotation of the rotating shaft 5 causes the connecting shaft 6 to rotate coaxially, and the first gear 8 on the outer surface of the connecting shaft 6 rotates. This rotation of the first gear 8 drives the third gear 243 in the blower mechanism 24 to rotate, which in turn drives the second shaft 242 to rotate. The rotation of the second shaft 242 causes the blades 244 fixedly connected to it to rotate, creating axial airflow. The axial airflow in the sealing pipe 245 enters the curved hole 32 of the mounting plate 25 along the connecting pipe 247. The airflow in the curved hole 32 enters the mounting pipe 26 and is distributed along the outlet pipe 28 below the mounting pipe 26. The airflow discharged from the outlet pipe 28 blows along the top surface of the track plate 42, causing the track... Dust and impurities on the track slab 42 are blown away. As the crane unit moves, the cleaning frame 31 on the bottom surface of the buffer seat 30 pushes away solid obstacles on the track assembly 4. When the crane unit reaches the limit position, the buffer seat 30 contacts the limit baffle and drives the movable rod 29 to compress the spring 27, causing the spring 27 in the mounting tube 26 to compress. At the same time, the movable rod 29 moves along the inner wall of the mounting tube 26 and seals the top of the air outlet duct 28. The mounting tube 26 remains sealed. Before the internal power mechanism of the machine body 1 completely stops, the blade 244 continues to rotate with the second shaft 242 and the connecting shaft 6, causing the air pressure inside the mounting tube 26 to rise rapidly. Under the action of the internal air pressure, the blade 244 stops rotating, forcing the second shaft 242 and the connecting shaft 6 to stop. The crane unit stops quickly, and the operator performs the shutdown operation.
[0048] First, by adding a blower mechanism 24 to the end face of the body 1, the rotation of the connecting shaft 6, in conjunction with the rotation of the first gear 8 on the connecting shaft 6, enables the rotation of the third gear 243 in the blower mechanism 24. This causes the third gear 243 to drive the second shaft 242 to rotate, and in conjunction with the blades 244 fixedly connected to the second shaft 242, axial airflow is formed. The generated airflow is then introduced into the mounting pipe 26 through the curved hole 32 via the connecting pipe 247, and blown downwards onto the track plate 42 via the air outlet pipe 28. The airflow effect cleans the dust and impurities on the track plate 42, and the subsequent atomized lubricating oil adheres to the track plate 42, providing good lubrication when the rotating wheel 7 passes over it. This prevents the adhesion of impurities from increasing friction, improves the actual moving quality of the rotating wheel 7, enhances moving stability, and results in good performance.
[0049] Furthermore, by utilizing the meshing of gear 8 on connecting shaft 6 and gear 243 on shaft 242, shaft 242 is rotated, forming axial airflow with blades 244. This airflow is then introduced into mounting pipe 26 through connecting pipe 247. When buffer seat 30 performs a buffering collision, it immediately compresses movable rod 29 and seals mounting pipe 26. As blades 244 continue to rotate, a high-pressure space is formed in mounting pipe 26. The internal high-pressure reaction force is applied to blades 244, causing blades 244 and shaft 242 to stall, thereby stopping shaft 5 and connecting shaft 6. This achieves a rapid automatic stop, avoiding repeated movement and collisions of the overhead crane unit within the operator's reaction time, resulting in good performance.
