Abstract

The present invention relates to the field of crane guide ropes, and discloses a guide rope mechanism for a crane, including a mounting plate, a first fixed disk and a first winding rod. Support seats are arranged on both sides of the upper surface of the mounting plate, and the first fixed disk is fixedly installed on the support seats. During the hoisting process of the lifting rope, the corresponding two anti-sway plates on the limit anti-sway structure can be spliced through a pressing structure and a splicing structure. By wrapping the two anti-sway plates around the lifting rope, the lifting rope can be limited during the hoisting process, thereby reducing safety problems caused by the swaying of materials and improving safety. Moreover, during the upward hoisting process of the lifting rope, in cooperation with the winding structure, the two anti-sway plates can be automatically split and wound between them. Through the winding function of the anti-sway plates, the limit anti-sway structure can be used for anti-sway work in high-altitude hoisting operations, effectively increasing the limit anti-sway height and making it more convenient to use.

Description

Technical Field

[0001] The invention relates to the technical field of crane guide ropes, and in particular to a guide rope mechanism for a crane. Background Art

[0002] The crane mainly includes the lifting mechanism, operating mechanism, luffing mechanism, slewing mechanism and metal structure, etc. The lifting mechanism is the basic working mechanism of the crane, which is mostly composed of a hanging system and a winch, and there are also hydraulic systems to lift heavy objects; the operating mechanism is used to move heavy objects longitudinally and horizontally or adjust the working position of the crane, and is generally composed of a motor, a reducer, a brake and wheels. When the crane is in use, a guide rope mechanism is used;

[0003] Patent No. CN115385254A is a rope guide device for a crane. Through the driving action of a first threaded driving rod connected to the output end of a third servo motor, the first sliding sleeve block can be driven to move up and down on the inner wall of a first sliding slot box, and the height of a second sliding slot box can be automatically adjusted. Through the driving action of a second threaded driving rod connected to the output end of a fourth servo motor, the second sliding sleeve block inside the second sliding slot box can be driven to move left and right, so that the rope guide sleeve plate can be adjusted in four directions, thereby improving the flexibility of the rope guide device of the crane during use.

[0004] However, when the guide rope mechanism in the prior art cooperates with the crane to work, the guide rope is prone to shaking during the process of lifting materials at high altitude due to the external environment or the unstable center of gravity of the lifted material, and even the material may fall from the altitude, which brings safety hazards to the lifting work. In addition, in the prior art, when preventing shaking, the guide tube is slided up and down to limit the guide rope, so as to perform the anti-sway work, which will result in a low lifting height.

Detailed implementation mode

[0029] The following is a further detailed description of the present invention in conjunction with the attached Figures 1-7 drawings.

[0030] Referring to Figures 1-7 , an embodiment of the present invention discloses a wire guiding mechanism for a crane, which includes a mounting plate 1, a first fixed disk 3 and a first winding rod 4. Support bases 2 are arranged on both sides of the upper surface of the mounting plate 1. The first fixed disk 3 is fixedly installed on the support base 2. The first winding rod 4 rotatably passes through the axial center positions of the two first fixed disks 3. A lifting rope is connected to the first winding rod 4. A first motor 5 is installed at the middle of the left side surface of the left first fixed disk 3. One end of the output shaft of the first motor 5 is connected to the first winding rod 4. A wire guiding structure is arranged between the two first fixed disks 3. A winding structure is arranged at the middle of the front surface of the mounting plate 1. A limiting and anti-sway structure is arranged on the mounting plate 1 through the winding structure;

[0031] The anti-sway limiting structure includes two groups of anti-sway plates 8 arranged through a winding structure. The two lowermost anti-sway plates 8 are rotatably connected to the hook at the bottom end of the suspension rope. A groove 9 is formed on one side of each anti-sway plate 8. A connecting block 11 is connected to the top end of each anti-sway plate 8, and a U-shaped rod 10 is connected to the bottom end of each anti-sway plate 8. The connecting block 11 is movably sleeved on the U-shaped rod 10. The distance between the two vertically arranged anti-sway plates 8 is 0.2 CM. An installation frame 6 is connected to the front side of the lower part of the installation plate 1. A fixed frame 7 is installed in the middle of the front surface of the installation frame 6. The two groups of anti-sway plates 8 pass through the fixed frame 7. A splicing structure is arranged between the two groups of anti-sway plates 8. Pressing structures are arranged at the lower parts of the two side surfaces of the fixed frame 7. First guiding structures are arranged in the middle of the upper surface of the fixed frame 7. A pushing bar 62 is connected to the middle of the inner wall of the front side of the fixed frame 7. While starting the first motor 5 to drive the first winding rod 4 to rotate and lower the suspension rope, the two groups of anti-sway plates 8 can be lowered from the winding structure, and the corresponding anti-sway plates 8 between the two groups are spliced in sequence, so that the corresponding anti-sway plates 8 can be wrapped around the suspension rope. In this way, the two mutually spliced anti-sway plates 8 can be used to limit the suspension rope, thereby reducing the safety problems caused by the sway of the material during hoisting.

[0032] See Figures 1-4 , the splicing structure includes a slot 16 formed on one side of one group of anti-sway plates 8. A clamping groove 17 is formed at the left end of the upper slot wall of the slot 16. A sliding groove 13 is formed on one side of the other group of anti-sway plates 8. A slider 12 is slidably arranged in the sliding groove 13. A first spring 14 is connected between the slider 12 and the bottom slot wall of the sliding groove 13. A clamping bar 15 is connected to the slider 12;

[0033] The winding structure includes two second winding rods 18 rotatably connected to the middle of the front surface of the installation plate 1. The two uppermost anti-sway plates 8 are rotatably connected to the second winding rods 18. A first gear 20 is fixedly sleeved on the second winding rod 18 near the rear end. The two first gears 20 are meshed and connected. Second fixing discs 19 are fixedly sleeved on the second winding rod 18 near both ends. A through groove 21 is formed on the installation plate 1 near one of the second winding rods 18. A second motor 22 is installed on the front slot wall of the through groove 21. One end of the output shaft of the second motor 22 is connected to one of the second winding rods 18;

[0034] The first guiding structure includes fixing seats 23 fastened to the middle of the two sides of the upper surface of the fixed frame 7 by screws. A rotating shaft 24 rotatably passes through the top end of the fixing seat 23. A first limiting wheel 25 is rotatably sleeved on the middle of the rotating shaft 24. The first limiting wheel 25 plays a limiting role on the anti-sway plate 8, so that when pressing, the corresponding two anti-sway plates 8 can be smoothly spliced together;

[0035] The pressing structure includes cylinders 26 installed at the lower parts of the left and right sides of the fixed frame 7. The output shafts of the cylinders 26 pass through one end of the fixed frame 7 and are installed with pressing seats 27. The pressing seats 27 are in a "U" shape. When the second motor 22 is started to drive one of the second winding rods 18 to rotate, through two first gears 20, the two second winding rods 18 can be driven to rotate simultaneously, so as to wind or lower two groups of anti-sway plates 8. And when lowering the anti-sway plates 8, the cylinders 26 can be started to drive the pressing seats 27 to move towards the middle, and use the pressing seats 27 to push the two anti-sway plates 8 towards the middle. During the process that the clamping strip 15 on one of the anti-sway plates 8 is inserted into the slot 16 on the other anti-sway plate 8, the inclined surface on the clamping strip 15 first presses the wall of the slot 16 on the slot 16, and drives the clamping strip 15 to drive the slider 12 to slide downwards in the chute 13, squeezing the first spring 14 to compress. When the clamping strip 15 is completely inserted into the slot 16, by using the restoring force of the first spring 14 on the slider 12, the clamping strip 15 can be pushed into the clamping groove 17 to perform the automatic splicing work of the two anti-sway plates 8. At this time, there is a spacing of 0.2 CM between the corresponding two anti-sway plates 8. In this way, when the second winding rod 18 rotates in the reverse direction to drive the anti-sway plate 8 to move upwards and wind, the anti-sway plate 8 moves upwards to drive the clamping strip 15 to contact the pushing strip 62. As the anti-sway plate 8 continues to move upwards, the pushing strip 62 pushes the clamping strip 15 to move relatively downwards on the anti-sway plate 8, and the clamping strip 15 is pushed out of the clamping groove 17. As the second winding rod 18 rotates and winds, the pulling force generated on the anti-sway plate 8 can automatically pull apart the two spliced anti-sway plates 8, so as to perform the winding work on the anti-sway plates 8.

[0036] See Figures 5-7 , the rope guiding structure includes mounting seats 31 fastened to the front side of the first fixed disk 3 by screws. A cross bar 32 is connected between the two mounting seats 31. Two spiral grooves 33 are formed on the cross bar 32. The spiral directions of the two spiral grooves 33 are opposite, and the ends of the two spiral grooves 33 are communicated with each other. A first moving pipe 34 is movably sleeved on the cross bar 32. An installation sleeve 37 is fixedly sleeved in the middle of the first moving pipe 34. A first guide wheel 36 is rotatably sleeved in the middle of the installation sleeve 37. A plug rod 35 is fixedly inserted near the left end of the first moving pipe 34. One end of the plug rod 35 in a hemispherical shape is slidably inserted into one of the spiral grooves 33. A second guiding structure is arranged above the first guide wheel 36 between the two mounting seats 31. L-shaped strips 28 are connected to the front sides of the two first fixed disks 3 below the mounting seats 31. A fixing rod 29 is connected between the two ends of the two L-shaped strips 28 close to each other. A second limiting wheel 30 is rotatably sleeved on the fixing rod 29;

[0037] The second guiding structure includes a vertical plate 38 connected to the upper side edge of the mounting base 31. A cross plate 39 is fixedly connected between the two vertical plates 38. A second moving pipe 40 is movably sleeved on the cross plate 39. The end face of the cross plate 39 is square. A second guide wheel 41 is rotatably sleeved in the middle of the second moving pipe 40. A cleaning structure and a maintenance structure are respectively arranged on the second moving pipe 40.

[0038] The cleaning structure includes first connecting strips 42 connected to the lower parts of both ends of the second moving pipe 40. A fixing ring 43 is installed between the mutually approaching ends of the two first connecting strips 42. A cleaning ring 44 is rotatably passed through the fixing ring 43. Brush hairs are arranged on the inner wall of the cleaning ring 44. A second gear 45 is fixedly sleeved at the front end of the cleaning ring 44. A cross bar 46 is connected between the two mounting bases 31. The second gear 45 is meshed with the teeth on the cross bar 46.

[0039] The maintenance structure includes second connecting strips 47 connected to the rear sides of both ends of the second moving pipe 40. A mounting disc 48 is installed between the mutually approaching ends of the two second connecting strips 47. An oil storage bottle 49 is fixedly arranged on the upper part of the mounting disc 48. An oil inlet pipe 50 with a rotary cover is connected to the top end of the oil storage bottle 49. A lower oil pipe 51 connected to the bottom end of the oil storage bottle 49 penetrates through the mounting disc 48. An electric valve 52 is installed on the lower oil pipe 51. A dripping oil pipe 53 is connected to the bottom end of the lower oil pipe 51. Under the action of a heavy object, the guide rope is pulled to be tightened on the first guide wheel 36. In this way, during the winding process of the lifting rope, the first moving pipe 34 and the first guide wheel 36 as a whole will rotate on the cross bar 32. In this way, one end of the inserting rod 35 is driven by the first moving pipe 34 to slide in the spiral groove 33, and the first guide wheel 36 will be driven to reciprocate on the cross bar 32, so as to wind the lifting rope to various positions on the first winding rod 4. At the same time, since the lifting rope passes between the first guide wheel 36 and the second guide wheel 41, the reciprocating movement of the first guide wheel 36 will also pull the second guide wheel 41 and the second moving pipe 40 as a whole to move back and forth on the cross plate 39 through the lifting rope. The movement of the second guide wheel 41 drives the second gear 45 to roll on the cross bar 46, so as to drive the cleaning ring 44 to automatically rotate on the fixing ring 43. By using the brush hairs on the inner wall of the cleaning ring 44, the sundries on the lifting rope passing through the cleaning ring 44 can be automatically cleaned. When the lifting rope needs to be maintained, the electric valve 52 on the lower oil pipe 51 can be opened to open the lower oil pipe 51, so as to drip the lubricating oil in the oil storage bottle 49 onto the lifting rope through the dripping oil pipe 53 to maintain the lifting rope.

[0040] The implementation principle of a wire guiding mechanism for a crane in an embodiment of the present invention is as follows: First, start the first motor 5 to drive the first winding rod 4 to rotate and lower the lifting rope. At the same time, when starting the second motor 22 to drive one of the second winding rods 18 to rotate, through two first gears 20, the two second winding rods 18 can be driven to rotate simultaneously to lower two groups of anti-sway plates 8. And when lowering the anti-sway plates 8, the air cylinder 26 can be started to drive the pressing seat 27 to move towards the middle, and use the pressing seat 27 to push the two anti-sway plates 8 towards the middle. During the process that the clamping strip 15 on one of the anti-sway plates 8 is inserted into the slot 16 on the other anti-sway plate 8, the inclined surface on the clamping strip 15 first squeezes the slot wall of the slot 16, driving the clamping strip 15 to drive the slider 12 to slide downward in the chute 13, squeezing the first spring 14 to compress. When the clamping strip 15 is completely inserted into the slot 16, using the restoring force of the first spring 14 on the slider 12, the clamping strip 15 can be pushed into the clamping groove 17 to automatically splice the two anti-sway plates 8. By splicing the corresponding anti-sway plates 8 in two groups in sequence, including the lifting rope, when the hook at the bottom end of the lifting rope hooks the material, start the first motor 5 to drive the first winding rod 4 to rotate in the reverse direction to lift the material. In this way, by using the anti-sway plates 8 to limit the lifting rope, the shaking of the material can be reduced during the lifting process. And during the lifting process, the second motor 22 drives the second winding rod 18 to rotate in the reverse direction. At the same time, the winding of the lifting rope drives the anti-sway plates 8 to move upward, driving the clamping strip 15 to contact and push away the pushing strip 62. As the anti-sway plates 8 continue to move upward, the pushing strip 62 pushes the clamping strip 15 to move relatively downward on the anti-sway plates 8, and the clamping strip 15 is pushed out of the clamping groove 17. As the second winding rod 18 rotates and winds up, the pulling force generated on the anti-sway plates 8 can automatically pull apart the two spliced anti-sway plates 8. Thus, during the lifting process of the material, the anti-sway plates 8 are wound up in sequence to realize the lifting work. And when carrying out the lifting work, since there is a heavy object hanging on the lifting rope, under the action of the heavy object, the wire guiding rope is pulled tightly on the first guide wheel 36. In this way, during the winding process of the lifting rope, it will drive the first moving pipe 34 and the first guide wheel 36 as a whole to rotate on the cross bar 32. In this way, using the first moving pipe 34 to drive one end of the inserting rod 35 to slide in the spiral groove 33 will drive the first guide wheel 36 to reciprocate on the cross bar 32, so as to wind the lifting rope to various positions on the first winding rod 4. At the same time, since the lifting rope passes between the first guide wheel 36 and the second guide wheel 41, the reciprocating movement of the first guide wheel 36 will also pull the second guide wheel 41 and the second moving pipe 40 as a whole to move back and forth on the cross plate 39 through the lifting rope. The movement of the second guide wheel 41 drives the second gear 45 to roll on the cross bar 46, driving the cleaning ring 44 to automatically rotate on the fixed ring 43. Using the bristles on the inner wall of the cleaning ring 44, the sundries on the lifting rope passing through the cleaning ring 44 can be automatically cleaned. When it is necessary to maintain the lifting rope, the electric valve 52 on the lower oil pipe 51 can be opened to open the lower oil pipe 51 to pour the lubricating oil in the oil storage bottle 49,Oil is dripped onto the suspension rope through the oil dripping pipe 53 to perform maintenance work on the suspension rope.

[0041] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
