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; 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. 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.

A connecting block 11 is connected to the top of each anti-sway plate 8. The bottom of each anti-sway plate 8 is connected to a U-shaped rod 10. The connecting block 11 is movably sleeved on the U-shaped rod 10. The spacing between the two vertical anti-sway plates 8 is 0.2CM. The front side of the lower side of the mounting plate 1 is connected to the mounting frame 6. The middle of the front side of the mounting frame 6 is installed with a fixed frame 7. The two groups of anti-sway plates 8 pass through the fixed frame 7. A splicing structure is arranged in the middle, a pressing structure is arranged at the lower parts of both side surfaces of the fixed frame 7, a first guiding structure is arranged at the middle part of the upper part of the fixed frame 7, a pushing strip 62 is connected to the middle part of the inner wall on the front side of the fixed frame 7, when the first motor 5 is started to drive the first winding rod 4 to rotate and lower the lifting rope, two groups of anti-sway plates 8 can be lowered from the winding structure, and the two groups of corresponding anti-sway plates 8 are spliced ​​in turn, so that the corresponding anti-sway plates 8 can be wrapped around the lifting rope, in this way, the two groups of anti-sway plates 8 spliced ​​with each other can be used to limit the lifting rope, thereby reducing the safety problems caused by the shaking of the material when lifting the material.

[0018] See also Figure 1-Figure 4 The splicing structure includes a slot 16 provided on one side of one set of anti-sway plates 8, a card slot 17 provided at the left end of the slot wall on the slot 16, a slide slot 13 provided on one side of the other set of anti-sway plates 8, a slider 12 slidably provided in the slide slot 13, a first spring 14 connected between the slider 12 and the slot wall at the bottom end of the slide slot 13, and a card strip 15 connected to the slider 12; The winding structure includes two second winding rods 18 rotatably connected to the front of the mounting plate 1 near the middle, the two top anti-sway plates 8 are rotatably connected to the second winding rods 18, a first gear 20 is fixedly sleeved near the rear end of the second winding rod 18, the two first gears 20 are meshed and connected, and a second fixed plate 19 is fixedly sleeved near both ends of the second winding rod 18, a through slot 21 is opened on the mounting plate 1 near one of the second winding rods 18, a second motor 22 is installed on the front side of the through slot 21, and one end of the output shaft of the second motor 22 is connected to one of the second winding rods 18; The first guide structure includes a fixing seat 23 fastened by screws at the middle of both sides of the fixing frame 7, a rotating shaft 24 is rotatably passed through the top of the fixing seat 23, and a first limiting wheel 25 is rotatably sleeved at the middle of the rotating shaft 24, and the first limiting wheel 25 has a limiting effect on the anti-sway plate 8, so that when pressed, the corresponding two anti-sway plates 8 can be smoothly spliced ​​together; The pressing structure includes a cylinder 26 installed at the lower part of the left and right sides of the fixed frame 7. The output shaft of the cylinder 26 passes through one end of the fixed frame 7 to install a pressing seat 27. The pressing seat 27 is in a "U" shape. When the second motor 22 is started to drive one of the second winding rods 18 to rotate, the two first gears 20 can be used to drive the two second winding rods 18 to rotate at the same time, so as to reel in or lower the two sets of anti-sway plates 8. When lowering the anti-sway plates 8, the cylinder 26 can be started to drive the pressing seat 27 to move toward the middle. The pressing seat 27 is used to push the two anti-sway plates 8 toward the middle. When the card 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 of the card strip 15 first squeezes the slot wall on the slot 16, pushing the card strip 15 to drive the slider 12 in the slide groove 13. When the first spring 14 is pressed and the card strip 15 is fully inserted into the slot 16, the elastic force of the first spring 14 is used to reset the slider 12, so as to push the card strip 15 into the card slot 17, and the two anti-sway plates 8 are automatically spliced ​​together. At this time, there is a 0.2CM spacing between the two corresponding anti-sway plates 8. In this way, when the second winding rod 18 rotates in the opposite direction to drive the anti-sway plate 8 to move up and reel, the anti-sway plate 8 moves up and drives the card strip 15 to contact the push-open strip 62. As the anti-sway plate 8 continues to move up, the push-open strip 62 pushes the card strip 15 to move relatively downward on the anti-sway plate 8, and the card strip 15 is pushed out of the card slot 17. As the second winding rod 18 rotates and reels, the pulling force generated on the anti-sway plate 8 can automatically pull apart the two anti-sway plates 8 spliced ​​together, thereby reeling the anti-sway plate 8.

[0019] See also Figure 5-Figure 7 The guide rope structure includes a mounting seat 31 fastened by screws at the front side of the first fixed plate 3, a cross bar 32 is connected between the two mounting seats 31, and two spiral grooves 33 are opened 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 connected to each other. A first moving tube 34 is movably sleeved on the cross bar 32, and a mounting sleeve 37 is fixedly sleeved in the middle of the first moving tube 34. A first guide wheel 36 is rotatably sleeved on the middle of the mounting sleeve 37. An insertion rod 35 is fixedly inserted into the first moving tube 34 near the left end, and one end of the insertion rod 35 is hemispherical and slidably inserted into one of the spiral grooves 33. A second guide structure is provided between the two mounting seats 31 above the first guide wheel 36, and an L-shaped strip 28 is connected to the front side of the two first fixed plates 3 below the mounting seat 31. A fixing rod 29 is connected between the two L-shaped strips 28 close to one end, and a second limiting wheel 30 is rotatably sleeved on the fixing rod 29; The second guide structure includes a vertical plate 38 connected to the upper edge of one side of the mounting seat 31, a horizontal plate 39 is fixedly connected between the two vertical plates 38, a second moving tube 40 is movably sleeved on the horizontal plate 39, the end surface of the horizontal plate 39 is square, a second guide wheel 41 is rotatably sleeved in the middle of the second moving tube 40, and a cleaning structure and a maintenance structure are respectively provided on the second moving tube 40; The cleaning structure includes a first connecting bar 42 connected to the lower part of the two ends of the second moving tube 40, a fixing ring 43 is installed between the two first connecting bars 42 close to each other, a cleaning ring 44 rotates through the fixing ring 43, bristles 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 horizontal bar 46 is connected between the two mounting seats 31, and the second gear 45 is meshedly connected with the teeth on the horizontal bar 46; The maintenance structure includes a second connecting strip 47 connected to the rear sides of both ends of the second moving tube 40, a mounting plate 48 is installed between the two second connecting strips 47 close to each other at one end, an oil storage bottle 49 is fixedly installed on the mounting plate 48, the top of the oil storage bottle 49 is connected to an oil inlet pipe 50 with a rotating cover, the bottom of the oil storage bottle 49 is connected to a lower oil pipe 51 passing through the mounting plate 48, an electric valve 52 is installed on the lower oil pipe 51, and an oil dripping pipe 53 is connected to the bottom of the lower oil pipe 51. Under the action of the weight, the guide rope is pulled tight on the first guide wheel 36, so that the first moving tube 34 and the first guide wheel 36 will be driven to rotate as a whole on the cross bar 32 during the winding process, so that the first moving tube 34 is used to drive one end of the plug rod 35 to slide in the spiral groove 33, which will drive the first guide wheel 36 on the cross bar 32 The reciprocating movement is used to reel the rope to various positions on the first reeling rod 4. At the same time, since the 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 movable tube 40 as a whole to move back and forth on the cross plate 39 through the rope. The movement of the second guide wheel 41 drives the second gear 45 to roll on the cross bar 46, driving the cleaning circle 44 to automatically rotate on the fixed ring 43. The bristles on the inner wall of the cleaning circle 44 can be used to automatically clean the rope debris passing through the cleaning circle 44. When the 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 to drip the lubricating oil in the oil storage bottle 49 onto the rope through the oil dripping pipe 53 to maintain the rope.

[0020] The implementation principle of a rope guide mechanism for a crane in an embodiment of the present invention is as follows: first, the first motor 5 is started to drive the first winding rod 4 to rotate and lower the lifting rope. At the same time, when the second motor 22 is started to drive one of the second winding rods 18 to rotate, the two second winding rods 18 can be driven to rotate at the same time through the two first gears 20 to lower the two sets of anti-sway plates 8. When the anti-sway plates 8 are lowered, the cylinder 26 can be started to drive the pressing seat 27 to move toward the middle. The pressing seat 27 is used to push the two anti-sway plates 8 toward the middle. During the process of inserting the clamping strip 15 on one of the anti-sway plates 8 into the slot 16 on the other anti-sway plate 8, the inclined surface of the clamping strip 15 first squeezes the slot wall on the slot 16, pushing the clamping strip 15 to drive the slider 12 in the slide groove 13. When the slider 12 is reset by the elastic force of the first spring 14, the card strip 15 can be pushed into the card slot 17 to automatically splice the two anti-sway plates 8, and the two sets of corresponding anti-sway plates 8 are spliced ​​in turn, including the lifting rope. When the hook at the bottom end of the lifting rope hooks the material, the first motor 5 is started to drive the first winding rod 4 to rotate in the opposite direction to lift the material. In this way, the anti-sway plate 8 is used to limit the lifting rope, and the shaking of the material can be reduced during the lifting process. In the lifting process, the second motor 22 drives the second winding rod 18 to rotate in the opposite direction. At the same time, the winding of the lifting rope drives the anti-sway plate 8 to move up and drives the card strip 15 to contact the push-open strip 62. As the sway plate 8 continues to move upward, the push-open bar 62 pushes the card strip 15 to move downward relatively on the anti-sway plate 8, and the card strip 15 is pushed out from the card slot 17. As the second winding rod 18 rotates and winds up, the tension generated on the anti-sway plate 8 can automatically pull apart the two anti-sway plates 8 spliced ​​together, so that in the process of lifting the material, the anti-sway plates 8 are wound up in turn to achieve the lifting work, and when the lifting work is being carried out, because there is a heavy object hanging on the lifting rope, under the action of the heavy object, the guide rope is pulled tight on the first guide wheel 36, so that the lifting rope will drive the first moving tube 34 and the first guide wheel 36 to rotate as a whole on the cross bar 32 during the winding process, so that the first moving tube 34 is used to drive one end of the insertion rod 35 to slide in the spiral groove 33, which will drive the first The guide wheel 36 moves back and forth on the cross bar 32, so as to reel the rope to various positions on the first reeling rod 4. At the same time, since the 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 tube 40 to move back and forth on the cross plate 39 as a whole through the 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 circle 44 to automatically rotate on the fixed ring 43. The brush on the inner wall of the cleaning circle 44 can be used to automatically clean the rope debris passing through the cleaning circle 44. When the 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 to release the lubricating oil in the oil storage bottle 49.The oil is dripped onto the suspension rope through the oil dripping pipe 53 to perform maintenance work on the suspension rope.

[0021] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
