Description

Technical Field

[0001] The invention relates to the technical field of monorail cranes, and in particular to a curved running and turnable monorail crane. Background Art

[0002] A monorail crane is a device used to transport workpieces or materials. It is mainly composed of a track, a driving trolley and an electric hoist. The track is usually composed of I-beams, which can be bent into an arc shape to achieve curved operation and turning of the driving trolley. The track is often fixed to the ceiling of the building by embedded bolts. The driving wheels and rollers on the driving trolley are all fitted on the track. The driving wheels are driven by a motor to move the driving trolley on the track. The motor is installed on the side panel of the driving trolley, and the electric hoist is installed at the bottom of the side panel of the driving trolley. It is used for lifting materials or workpieces. A sliding wire is often installed on the side of the track. The collector on the driving trolley adheres to the slide wire and moves along the marked surface when the driving trolley moves, thereby realizing power supply to the driving trolley and the electric hoist. At the same time, when the driving trolley or the electric hoist needs to be repaired, the maintenance personnel need to be lifted to a high place with the help of lifting equipment, and then the electric hoist and the driving trolley are removed from the track at a high place, and then the maintenance personnel together with the electric hoist and the driving trolley are lowered to the ground with the lifting equipment, and then the electric hoist and the driving trolley are repaired. After the maintenance is completed, the repaired electric hoist and driving trolley need to be lifted to the track and then installed on the track.

[0003] During the use of common curved-running turnable monorail cranes, when the electric hoist and the driving trolley are damaged and need to be repaired, the maintenance personnel must use lifting equipment to rise to a height to work because the electric hoist and the driving trolley are installed at a high position. When disassembling at a height, due to the heavy weight of the electric hoist and the driving trolley, not only is the operation difficult, but also additional support is required to ensure the smooth disassembly process. After the disassembly is completed, the maintenance personnel also need to use the lifting equipment to transport the parts to the ground for maintenance. After the maintenance is completed, the electric hoist and the driving trolley must be raised to a height by the lifting equipment again, and the installation is completed at a height. During the entire maintenance process, not only complex disassembly and assembly operations must be performed at a height, but also the lifting of the heavy electric hoist and driving trolley must be handled. The safety and convenience of the maintenance process needs to be improved. Therefore, the present application provides a curved-running turnable monorail crane to meet the needs. Summary of the invention

[0011] Preferably, a notch is provided on the side of the movable plate, the notch is located below the movable track, and a protrusion is provided on the inner wall of the notch, grooves are provided on opposite sides of the protrusion, a through groove is provided inside the rotating shaft, a limit pin is slidably connected to the inner wall of the through groove, one end of the limit pin is flush with the end of the rotating shaft, a columnar block is fixed to the other end of the limit pin, the columnar block fits with the inner wall of the groove, an annular groove is provided on the inner wall of the through groove, a circular ring is sleeved on the circumferential surface of the limit pin, and a tension spring is fixed to the side of the circular ring close to the columnar block.

The limit block is fixed on the side of the side plate of the driving trolley, and the position of the limit block corresponds to the position of the limit pin. When disassembling the movable track, the nut is unscrewed from the screw rod, and the movable plate is rotated downward. During the downward rotation of the movable plate, the inner wall of the groove on the raised part is driven to squeeze the columnar block, so that the columnar block drives the limit pin to extend from the rotating shaft, thereby realizing the limiting of the driving trolley during the lifting and lowering process on the movable track.

[0012] Preferably, the inner wall of the groove is a curved surface, and the shape of the columnar block matches the shape of the inner wall of the groove.

[0013] Preferably, an infrared sensor is embedded on the inner wall of the annular groove, and an audible and visual alarm light is installed on the top of the movable track, and the audible and visual alarm light is electrically connected to the infrared sensor.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, through the setting of the lifting drive component and the movable track, when performing maintenance, it is only necessary to move the driving trolley to the movable track, release the fixing of the movable track by the connecting mechanism, and start the lifting drive component, so that the movable track together with the driving trolley and the electric hoist can be smoothly moved down to the ground, which is convenient for maintenance personnel to carry out operations. After the maintenance is completed, the three are moved up through the lifting drive component, and the movable track and the fixed track are reconnected using the connecting mechanism. The whole process does not require maintenance personnel to perform tedious disassembly and lifting of the driving trolley and the electric hoist at a height, thereby improving the convenience and safety of the maintenance process.

[0016] Through the arrangement of the upper positioning assembly and the lower positioning assembly, when disassembling the connecting mechanism, the maintenance personnel only need to remove the nut at the lower positioning assembly to realize the lowering of the movable track. During the lowering process, the positioning bar of the upper positioning assembly will automatically separate from the positioning block, and when raising the movable track, the positioning bar is embedded in the inner wall of the positioning groove of the positioning block, so as to realize the positioning of the top of the movable track and the fixed track. Subsequently, the nut is tightened to fix the movable plate, thereby realizing the positioning of the bottom of the movable track and the fixed track. The operation is simple, and no tedious disassembly and assembly steps are required when fixing and disassembling the movable track, thereby further improving the convenience and safety of the maintenance process.

[0017] By setting the limit pin, after the nut fixing the movable plate is unscrewed, the movable track descends, and the movable plate flips downward under the action of its own gravity, thereby driving the inner wall of the groove of the raised part to squeeze the columnar block, so that the limit pin extends from the rotating shaft and cooperates with the limit block to effectively limit the displacement of the driving trolley during the descending process of the movable track. When the movable track rises, the movable plate is also in a flipped-down state, and the limit pin can still limit the driving trolley. During the raising and lowering process of the movable track, the driving trolley and the electric hoist can be prevented from slipping off the movable track without manual support, thereby further improving the safety and convenience during the maintenance process.

[0018] Through the setting of infrared sensors, when the movable track is fixed, the vibration generated by the driving trolley moving on the movable track may cause the nut to loosen. Once the nut is loose, the movable plate will rotate downward, thereby driving the limit pin to move through the cooperation of the protrusion and the columnar block, and the limit pin drives the ring to move. The infrared sensor will sense the displacement of the ring and trigger the sound and light alarm to alert personnel in time that there is an abnormality at the connection between the movable track and the fixed track, ensuring the safe driving of the driving trolley.

[0019] Through the setting of inclined plane three and inclined plane four, after the movable track is connected to the fixed track, the fitting of inclined plane three on the movable track and inclined plane four on the fixed track is utilized to realize the tight connection and accurate positioning of the joint between the movable track and the fixed track, effectively preventing misalignment between the two from affecting the normal operation of the driving trolley.

[0028] like Figure 2 and Figure 4 As shown, in this embodiment, the connecting mechanism 6 includes an upper positioning component 7 arranged on the top of the movable track 4 and a lower positioning component 13 arranged on the bottom of the movable track 4. The upper positioning component 7 is used to position the top position of the movable track 4 and the fixed track 3, and the lower positioning component 13 is used to position the bottom position of the movable track 4 and the fixed track 3. The upper positioning component 7 and the lower positioning component 13 accurately position the top and bottom of the movable track 4 and the fixed track 3 respectively, so as to realize a stable and tight connection between the movable track 4 and the fixed track 3.

[0029] like Figure 2 , Figure 8 and Fig. 9As shown, in the present embodiment, the upper positioning assembly 7 includes a plurality of positioning bars 8 fixed on the top of the movable rail 4, a positioning block 10 is fixed on the top of the fixed rail 3, the bottom of the positioning block 10 is fitted with the top of the movable rail 4, and a positioning groove 11 is provided on the side of the positioning block 10, the inner wall of the positioning groove 11 is fitted with the side of the positioning bar 8, the lifting drive member 5 is a winch, and the end of the wire rope of the lifting drive member 5 is fixedly connected to the top of the positioning bar 8, the positioning bar 8 is tightly matched with the positioning groove 11 of the positioning block 10, and when the movable rail 4 is fitted with the fixed rail 3, the positioning bar 8 is tightly fitted with the inner wall of the positioning groove 11, so as to realize the positioning of the movable rail 4 and the top of the fixed rail 3. The winch serves as a lifting drive component 5. Through the wire rope fixedly connected to the top of the positioning bar 8, it can stably drive the movable track 4, the driving trolley 1 and the electric hoist 2 to rise and fall, thereby ensuring the smooth movement of the equipment during maintenance. At the same time, the winch is also equipped with an electromagnetic brake. When the winch stops running, it is in a braking state. At this time, the wire rope also plays a positioning role for the movable track 4. The braking state is automatically released when the winch is running, so as not to affect the lifting and lowering of the movable track 4.

[0030] like Figure 8 and Fig. 9 As shown, in the present embodiment, the side surface of the positioning bar 8 is provided with a slope 19, and the inner wall of the positioning groove 11 is provided with a slope 2 12, and the slope 19 is fitted with the slope 2 12. By the mutually fitting arrangement of the slope 19 and the slope 2 12, when the movable track 4 rises and docks with the fixed track 3, it plays a role of auxiliary positioning and guiding, so that the positioning bar 8 can be more smoothly embedded in the positioning groove 11. At the same time, the mutual fit between the slope 19 and the slope 2 12 enhances the positioning stability between the positioning bar 8 and the positioning block 10, ensures that the movable track 4 and the top of the fixed track 3 are tightly connected, and prevents misalignment from affecting the normal operation of the driving trolley 1.

[0031] like Figure 2 As shown, in the present embodiment, a reinforcing rib is fixed on the top of the positioning block 10, and the reinforcing rib is fixed on the top of the fixed rail 3. The reinforcing rib enhances the connection strength between the positioning block 10 and the fixed rail 3, and improves the structural stability of the positioning block 10, so that it can remain stable when subjected to the force during the rising and falling process of the movable rail 4 and the vibration and other external forces generated during the operation of the driving trolley 1, thereby ensuring the accuracy and reliability of positioning.

[0032] like Figure 4-Figure 7As shown, in this embodiment, the lower positioning assembly 13 includes a plurality of rotating shafts 15 arranged at the bottom of the movable track 4, a fixed block 14 is fixedly sleeved on the circumferential surface of the rotating shaft 15, and the fixed block 14 is fixed to the bottom of the movable track 4. A movable plate 16 is rotatably connected to the circumferential surface of the rotating shaft 15, and the side of the movable plate 16 close to the fixed block 14 is rotatably connected to the side of the fixed block 14. The movable plate 16 fits the bottom of the movable track 4 and the fixed track 3, and a long groove is opened at the top of the movable plate 16 corresponding to the position of the fixed track 3, and the bottom of the fixed track 3 A screw is fixed at the bottom, the screw fits with the inner wall of the long groove, and a nut is threadedly connected to the screw, and the nut is pressed on the bottom of the movable plate 16. The movable plate 16 is fixed to the bottom of the movable track 4 and the fixed track 3 through the threaded connection between the nut and the screw, so as to realize the positioning and connection of the bottom of the two. When the movable track 4 needs to be disassembled, the connection can be released by unscrewing the nut, which is easy to operate. During installation, the movable track 4 can be firmly fixed by tightening the nut, thereby ensuring the stability of the connection between the movable track 4 and the bottom of the fixed track 3, and providing guarantee for the smooth operation of the driving trolley 1.

[0033] like Figure 4-Figure 7 As shown, in this embodiment, a notch 17 is provided on the side of the movable plate 16, and the notch 17 is located below the movable track 4, and a protrusion 18 is provided on the inner wall of the notch 17, and grooves 19 are provided on the opposite sides of the protrusion 18, and a through groove is provided inside the rotating shaft 15, and the inner wall of the through groove is slidably connected with a limit pin 20, one end of the limit pin 20 is flush with the end of the rotating shaft 15, and a columnar block 21 is fixed to the other end of the limit pin 20, and the columnar block 21 is fitted with the inner wall of the groove 19, and an annular groove 22 is provided on the inner wall of the through groove, and a circular ring 23 is sleeved on the circumferential surface of the limit pin 20, and a tension spring 24 is fixed on the side of the circular ring 23 close to the columnar block 21, and one end of the tension spring 24 close to the columnar block 21 is fixedly connected to the side of the inner wall of the annular groove 22 close to the columnar block 21, and the limit pin 20 is located inside the tension spring 24, driving the trolley 1, a limit block 26 is fixed on the side of the side plate of the movable track 4, and the position of the limit block 26 corresponds to the position of the limit pin 20. When disassembling the movable track 4, the nut is unscrewed from the screw rod, and the movable plate 16 rotates downward. During the downward rotation of the movable plate 16, the inner wall of the groove 19 on the protrusion 18 is driven to squeeze the columnar block 21, so that the columnar block 21 drives the limit pin 20 to extend from the rotating shaft 15, so as to realize the limiting of the driving trolley 1 during the lifting and lowering process on the movable track 4. During the lifting and lowering process of the movable track 4, when the nut is unscrewed, the movable plate 16 rotates downward, and the limit pin 20 is extended and cooperated with the limit block 26 through the cooperation of the protrusion 18 and the columnar block 21, so as to effectively limit the displacement of the driving trolley 1 during the lifting and lowering process of the movable track 4, prevent the driving trolley 1 and the electric hoist 2 from slipping off the movable track 4, and ensure the safety during the maintenance process. When the movable plate 16 is rotated back to the horizontal position for installation, the tension spring 24 can retract the limit pin 20, and the retraction of the limit pin 20 will not affect the normal travel of the driving trolley 1.

[0034] like Figure 7 As shown, in this embodiment, the inner wall of the groove 19 is a curved surface, and the shape of the columnar block 21 is adapted to the shape of the inner wall of the groove 19. The adapted curved surface shape allows the columnar block 21 to move more smoothly in the groove 19. When the movable plate 16 rotates, it can more effectively squeeze the columnar block 21 to ensure that the limit pin 20 is smoothly extended.

[0035] like Figure 6 As shown, in this embodiment, an infrared sensor 25 is embedded on the inner wall of the annular groove 22, and an audible and visual alarm lamp (not shown in the figure) is installed on the top of the movable track 4. The audible and visual alarm lamp is electrically connected to the infrared sensor 25. When the movable track 4 is fixed, the vibration generated by the driving trolley 1 moving on the movable track 4 may cause the nut to loosen. Once the nut is loose, the movable plate 16 will rotate downward, and the limit pin 20 will be driven to move through the cooperation of the protrusion 18 and the columnar block 21. The limit pin 20 drives the ring 23 to move. At this time, the infrared sensor 25 senses the displacement change of the ring 23 and sends a signal to the information processing unit. The information processing unit controls the audible and visual alarm to alarm through the control unit, and promptly reminds personnel that there is an abnormality at the connection between the movable track 4 and the fixed track 3, ensuring the safe driving of the driving trolley 1 and avoiding safety accidents caused by loose track connection.

[0036] like Fig.10 and Fig.11 As shown, in the present embodiment, the end of the movable track 4 is provided with a bevel three 27, and the end of the fixed track 3 is provided with a bevel four 28, and the bevel three 27 is fitted with the bevel four 28. After the movable track 4 is connected with the fixed track 3, the fit of the bevel three 27 and the bevel four 28 is utilized to realize the tight connection and accurate positioning of the joint between the movable track 4 and the fixed track 3, effectively preventing misalignment between the two, ensuring that the driving trolley 1 can pass through the track connection smoothly, avoiding the influence of the track misalignment on the normal operation of the driving trolley 1, and improving the stability and reliability of the monorail crane operation.

[0037] Working principle: The driving trolley 1 carries the electric hoist 2 fixed at the bottom and moves along the track body composed of the fixed track 3 and the movable track 4. The track body provides guidance for the movement of the driving trolley 1. The fixed track 3 is firmly installed on the ceiling of the building. The end of the movable track 4 fits the end of the fixed track 3. The two are connected and positioned by the connecting mechanism 6 to ensure that the driving trolley 1 can smoothly pass through the connection and realize normal lifting operation. When the driving trolley 1 or the electric hoist 2 needs to be repaired, the driving trolley 1 is first moved to the movable track 4, and then the maintenance personnel are driven to rise to the movable track 4 by means of the lifting equipment, and the collector at the driving trolley 1 is first separated from the slide wire, and then the nut on the screw in the lower positioning assembly 13 is unscrewed with the help of a wrench. After the nut is separated from the movable plate 16, the movable plate 16 flips downward under the action of its own gravity, and the movable plate 16 drives the curved surface of the inner wall of the groove 19 on the raised portion 18 to squeeze the columnar block 21, so that the columnar block 21 drives the limit pin 20 to move along the inner wall of the through groove in the rotating shaft 15 and extend from the rotating shaft 15, and cooperate with the limit block 26 on the side panel of the driving trolley 1 to limit the driving trolley 1 on the movable track The movable track 4 is displaced during the descent process to prevent it from slipping. When the limit pin 20 extends from the rotating shaft 15, it drives the ring 23 to move along the inner wall of the annular groove 22. When the ring 23 moves, it drives the tension spring 24 to be in a stretched state, and the lifting drive member 5 is started. The lifting drive member 5 unwinds the wire rope, so that the positioning bar 8 moves down and separates from the positioning block 10. At the same time, the positioning bar 8 drives the movable track 4 together with the driving trolley 1 and the electric hoist 2 to move smoothly down to the ground. After the driving trolley 1 and the electric hoist 2 are lowered to the ground, the maintenance personnel can directly disassemble and repair the driving trolley 1 and the electric hoist 2 on the ground. During the descent of the movable track 4, the lifting equipment synchronously drives the maintenance personnel to descend; After the maintenance is completed, the driving trolley 1 is installed on the movable track 4, and the lifting drive component 5 is started again. The lifting drive component 5 reels the wire rope. During reeling, the movable track 4, the driving trolley 1 and the electric hoist 2 are pulled up through the positioning bar 8. The maintenance personnel rise synchronously with the lifting equipment. During the rising process of the movable track 4, the limit pin 20 still plays a limiting role to prevent the driving trolley 1 from slipping. When the movable track 4 rises to the docking position with the fixed track 3, the positioning bar 8 is inserted into the positioning groove 11 of the positioning block 10, and the bottom of the positioning block 10 is fitted with the bottom of the movable track 4, and the inclined surface 19 on the positioning bar 8 is fitted with the inclined surface 2 12 of the inner wall of the positioning groove 11 to achieve the positioning of the movable track 4 and the top of the fixed track 3. Subsequently, the movable plate 16 is rotated upward to a horizontal state so that the movable plate 16 is fitted with the bottom of the movable track 4 and the fixed track 3, and then the nut is tightened on the screw. The movable plate 16 is now fixed, thereby completing the positioning of the movable track 4 and the bottom of the fixed track 3. When the movable plate 16 rotates upward, the protrusion 18 is driven to rotate. When the movable plate 16 rotates to a horizontal state, the position of the groove 19 on the protrusion 18 corresponds to the position of the columnar block 21. At this time, the ring 23 drives the limit pin 20 to move in the opposite direction under the tension of the tension spring 24, so that the columnar block 21 fits with the inner wall of the groove 19. After fitting, the end of the limit pin 20 away from the columnar block 21 is flush with the end of the rotating shaft 15. After the movable track 4 is fixed, the inclined surface 3 27 at the end of the movable track 4 fits tightly with the inclined surface 4 28 at the end of the fixed track 3, ensuring that the joint between the movable track 4 and the fixed track 3 is tightly connected and accurately positioned to prevent misalignment from affecting the normal operation of the driving trolley 1. After the movable track 4 is installed, the collector is fitted on the slide line to realize the power supply to the driving trolley 1 and the electric hoist 2. During the operation of the driving trolley 1, after the movable track 4 is fixed, the vibration generated by the movement of the driving trolley 1 on the movable track 4 may cause the nut to loosen. Once the nut is loose, the movable plate 16 will rotate downward, and the limit pin 20 will be driven to move through the cooperation of the protrusion 18 and the columnar block 21, and the limit pin 20 will drive the ring 23 to move. At this time, the infrared sensor 25 embedded in the inner wall of the annular groove 22 senses the displacement change of the ring 23 and triggers the sound and light alarm to alarm, promptly reminding personnel that there is an abnormality at the connection between the movable track 4 and the fixed track 3, thereby ensuring the driving safety of the driving trolley 1. When disassembling the movable track 4, the movable plate 16 rotates downward to drive the ring 23 to move, which will also trigger the alarm of the sound and light alarm. However, at this time, the maintenance personnel are located at the movable track 4 driven by the lifting equipment. When the sound and light alarm sounds, the sound and light alarm can be directly turned off, and the sound and light alarm can be turned on after the movable track 4 is installed.
