Description

Technical Field

[0001] This invention relates to the field of hoisting technology, specifically to a hoisting device for steel structure installation. Background Technology

[0002] During steel structure construction, mobile gantry cranes can be used as hoisting equipment. The vertical lifting and lowering of the mobile gantry cranes can be used to lift and install the steel structure, increasing the convenience of the installation process.

[0003] When a mobile gantry crane is used to lift steel structures, the wire rope is typically wound and unwound using a winding mechanism. After the wire rope is unwound, it is exposed to the construction environment, and impurities can easily adhere to the surface of the spiral grooves. If these impurities are not removed from the spiral grooves in time, they will bend when the wire rope is wound around the winding mechanism during winding. At this time, the impurities can easily cause wear and tear on the wire rope, thus reducing its service life. Summary of the Invention

With the cleaning component, the spiral groove of the wire rope can be cleaned during the winding of the wire rope, thereby removing impurities inside the spiral groove.

[0009] As an optional embodiment of the hoisting device for steel structure installation described in this invention, the end of the slide rod is provided with a movable groove, a slider is slidably disposed in the movable groove, the insert is fixed to the lower surface of the slider, the inside of the slide rod is provided with a lifting groove, a lifting plate is elastically disposed in the lifting groove, a sliding plate is fixed to the surface of the slider, and the sliding plate is slidably disposed in the lifting groove.

[0010] As an optional embodiment of the hoisting device for steel structure installation described in this invention, a core rod is slidably arranged inside the slide rod, and an abutment platform is fixed at the end of the core rod. The abutment platform is slidably arranged inside the slide rod, and an abutment rod that abuts against the abutment platform is fixed on the lower surface of the slide plate.

[0011] As an optional solution of the hoisting device for steel structure installation described in this invention, the end of the sliding rod is fixed with a first limiting ball, and the inside of the annular sliding groove is provided with a first trajectory groove for the first limiting ball to slide. The first trajectory groove includes a first horizontal part, a first leftward part, a second horizontal part and a first rightward part that are connected together.

[0012] As an optional solution of the hoisting device for steel structure installation described in this invention, the end of the core rod is fixed with a second limiting ball, and the interior of the annular groove is provided with a second trajectory groove for the second limiting ball to slide. The second trajectory groove includes a third horizontal part, a second left-moving part, a fourth horizontal part, a third left-moving part, a second right-moving part, and a third right-moving part that are connected to each other.

[0013] As an optional embodiment of the hoisting device for steel structure installation described in this invention, the second retaining ring is elastically provided with a striking column, the surface of the striking column is fixed with a sliding protrusion, the outer surface of the first retaining ring is fixed with a fixing ring, the fixing ring is slidably connected to the second retaining ring, and the surface of the fixing ring is provided with a third trajectory groove for the sliding protrusion to slide.

[0014] As an optional embodiment of the hoisting device for steel structure installation described in this invention, the third track groove includes multiple sets of energy storage parts and striking parts arranged in sequence.

[0015] The present invention has the following beneficial effects: 1. This hoisting device for steel structure installation moves the cleaning component to contact the spiral groove during wire rope winding. The movement of the wire rope relative to the cleaning component allows it to clean the surface of the spiral groove, facilitating the removal of impurities. Simultaneously, during wire rope winding, the rotation of the second retaining ring relative to the first retaining ring causes the second retaining ring to rotate, which in turn drives the fixing plate to rotate synchronously. This allows the cleaning component to clean along the direction of the spiral groove, improving the thoroughness of cleaning and resulting in a better cleaning effect.

[0016] 2. The hoisting device for steel structure installation, when the second retaining ring rotates, drives the second gear to travel along the second gear ring, causing the second gear to rotate. The second gear drives the first rotating shaft to rotate through the second rotating shaft, the second bevel gear, and the first bevel gear. The first rotating shaft drives the cleaning part to rotate, thereby changing the contact position between the cleaning part and the spiral groove, reducing the wear of the cleaning part. At the same time, when the cleaning part rotates, the end of the cleaning part will lift the impurities inside the spiral groove to the outside, which has a material lifting effect, making it easier to discharge the impurities inside the spiral groove and further improving the cleaning effect.

[0017] 3. The hoisting device for installing the steel structure sets up several sets of brushes for the cleaning components. When the first rotating shaft rotates, it drives the sliding rod to slide along the annular groove, allowing the sliding rod to reciprocate left and right. During this reciprocating motion, the brushes rotate, ensuring that each reciprocating motion of the sliding rod causes the brushes to rotate in the same direction at a certain angle. This changes the contact surface between the brushes and the spiral groove, reducing brush wear, increasing brush lifespan, and further improving the cleaning effect.

[0018] 4. In the hoisting device for steel structure installation, when the second retaining ring rotates relative to the first retaining ring, the second retaining ring drives the striking column to rotate, causing the striking column to drive the sliding protrusion to slide along the third track groove. Before the cleaning component cleans the spiral groove, the striking column can reciprocate to strike the surface of the wire rope, causing the surface of the wire rope to vibrate and loosen the impurities inside the spiral groove. Then, in conjunction with the cleaning component, the inside of the spiral groove is cleaned, thus facilitating the removal of impurities and achieving a better cleaning effect.

[0036] 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.

[0037] Example 1, please refer to Figures 1-16A hoisting device for steel structure installation includes a movable seat 2 slidably mounted on a hoisting rail 1. A storage box 4 for winding a steel wire rope 3 is fixed to the lower surface of the movable seat 2. A cleaning box 5 is fixed to the lower surface of the storage box 4. Two sets of first retaining rings 6 that can engage with each other are slidably mounted inside the cleaning box 5. Second retaining rings 7 that can engage with each other are mounted on the surfaces of the two sets of first retaining rings 6. Several sets of fixing plates 8 are fixed to the inner surface of the second retaining rings 7. Cleaning components 9 are mounted on the fixing plates 8. The cleaning components 9 clean the surface of the steel wire rope 3 by winding the steel wire rope 3. A servo motor 10 is fixed to the surface of the first retaining ring 6. A first gear 11 is fixed to the output end of the servo motor 10. A first toothed ring 12 that meshes with the first gear 11 is fixed to the outer surface of the second retaining ring 7. The second retaining ring 7 drives the cleaning components 9 to clean along the spiral groove 301 of the steel wire rope 3 by rotation. The cleaning box 5 has a movable groove 13 inside, and an electric push rod 14 is fixedly installed on the inner wall of the movable groove 13. The output end of the electric push rod 14 is fixed to the outer surface of the first retaining ring 6.

[0038] In this technical solution, the movable seat 2 moves on the hanging rail 1. The existing technology can be used to drive the rollers to move along the I-beam of the hanging rail 1. The storage box 4 for winding the wire rope 3 includes a motor and a winding roller. The end of the wire rope 3 is fixed to the winding roller. The motor drives the winding roller to rotate and wind up the wire rope 3. The end of the wire rope 3 is fixed with a hook for hoisting. The movement of the movable seat 2 on the hanging rail 1 and the winding of the wire rope 3 by the storage box 4 are existing technologies and are not the innovation of this application. They will not be described in detail. In this technical solution, the first retaining ring 6, the second retaining ring 7, and the first toothed ring 12 are all set as two sets of semi-circular structures that can be spliced ​​into a complete circular structure. Electric push rods 14 are provided on the outer side of both sets of first retaining rings 6. The wire rope 3 is first made by twisting multiple layers of steel wires into strands, and then, with the core as the center, a certain number of strands are twisted into a spiral shape. Therefore, during the formation of the wire rope 3, a spiral groove 301 is formed on the surface of the wire rope 3. When the wire rope 3 is in use, impurities can easily enter the spiral groove 301. If the impurities are not removed from the spiral groove 301 in time, the wire rope 3 will bend when it is wound up. At this time, the impurities can easily cause wear to the wire rope 3, thereby reducing its service life. Therefore, the spiral groove 301 on the surface of the wire rope 3 should be cleaned at the same time as the wire rope 3 is wound up. Specifically, when cleaning the surface of the wire rope 3, firstly, the electric push rod 14 is used to clean the surface of the wire rope 3. The first retaining ring 6 is pushed to move, causing the two sets of first retaining rings 6 to engage. The first retaining ring 6 drives the second retaining ring 7 to move, causing the two sets of second retaining rings 7 to engage as well. At this time, the second retaining ring 7 drives the cleaning component 9 to move to the surface of the wire rope 3 and contact the surface of the spiral groove 301 of the wire rope 3. When the wire rope 3 is wound up, the wire rope 3 moves relative to the cleaning component 9, so that the cleaning component 9 cleans the surface of the spiral groove 301 of the wire rope 3, making it easier to remove impurities inside the spiral groove 301. When the wire rope 3 is unwound, the first retaining ring 6 is pulled by the electric push rod 14 to move, separating the cleaning component 9 from the wire rope 3 to avoid contact, thereby reducing wear when cleaning is not required. Since the spiral grooves 301 are spirally distributed on the surface of the wire rope 3, rather than being a straight structure, when the wire rope 3 is wound up, the entire wire rope 3 moves in a straight line. Therefore, when the cleaning component 9 cleans the spiral grooves 301 of the wire rope 3, the cleaning component 9 cannot move along the spiral direction of the spiral grooves 301. As a result, the cleaning component 9 will slide out of the spiral grooves 301, making it impossible for the cleaning component 9 to consistently clean the spiral grooves 301. To address this issue, the cleaning component 9 is positioned along the direction of the spiral grooves 301 of the wire rope 3. Simultaneously, when the wire rope 3 is wound up, the servo motor 10 drives the first gear 11 to rotate, the first gear 11 drives the first toothed ring 12 to rotate, the first toothed ring 12 drives the second retaining ring 7 to rotate, the second retaining ring 7 drives the fixing plate 8 to rotate, and the fixing plate 8 drives the cleaning component 9 to rotate synchronously. This allows the cleaning component 9 to clean along the direction of the spiral grooves 301 when the wire rope 3 is wound up in a straight line, thereby improving the thoroughness of the cleaning of the spiral grooves 301 by the cleaning component 9 and resulting in a better cleaning effect. In this technical solution, an electromagnet is provided on the first retaining ring 6, which can attract the second retaining ring 7. When the electric push rod 14 pulls the two sets of first retaining rings 6 to separate from the outside of the wire rope 3, the electromagnet is energized and attracts the second retaining ring 7, so that the second retaining ring 7 will not separate from the first retaining ring 6. When the electric push rod 14 pushes the two sets of first retaining rings 6 to engage, the electromagnet is de-energized, so that the first retaining ring 6 no longer attracts the second retaining ring 7, allowing the second retaining ring 7 to rotate relative to the first retaining ring 6. Furthermore, by providing a limiting ring 46 on the surface of the second retaining ring 7 and opening a limiting groove 47 inside the first retaining ring 6, the limiting ring 46 slides inside the limiting groove 47, so that the second retaining ring 7 will not separate from the first retaining ring 6 when rotating. The energization and de-energization of the electromagnet are existing technologies and are not the innovation of this application, so they will not be described in detail.

[0039] In Example 2, when the cleaning component 9 moves along the spiral direction of the spiral groove 301, the contact surface between the cleaning component 9 and the spiral groove 301 remains unchanged. This means that the cleaning position of the cleaning component 9 on the spiral groove 301 remains constant, which not only reduces the cleaning effect but also increases the wear at the contact point between the cleaning component 9 and the spiral groove 301. To address this problem, this example is an improvement based on Example 1. For details, please refer to... Figures 1-16 A first rotating shaft 15 is rotatably mounted on the fixed plate 8. The end of the cleaning component 9 is connected to the first rotating shaft 15. A first bevel gear 16 is fixed to the end of the first rotating shaft 15. A second bevel gear 17 that meshes with the first bevel gear 16 is rotatably mounted inside the fixed plate 8. A second rotating shaft 18 is fixed on the second bevel gear 17. A second gear 19 is fixed to the end of the second rotating shaft 18. A second toothed ring 20 that meshes with the second gear 19 is fixed to the surface of the first retaining ring 6.

[0040] In this technical solution, the cleaning component 9 includes several sets of brushes 901, which are circumferentially distributed on the outside of the first rotating shaft 15. The second gear ring 20 is rotatably disposed inside the second retaining ring 7. When the second retaining ring 7 rotates relative to the first retaining ring 6, the second retaining ring 7 rotates relative to the second gear ring 20, causing the second retaining ring 7 to drive the second gear 19 to move along the second gear ring 20, thus causing the second gear 19 to rotate. The rotation of the second gear 19 drives the second bevel gear 17 to rotate via the second rotating shaft 18. The rotation of the second bevel gear 17 drives the first bevel gear 16 to rotate, and the first bevel gear 16 rotates... The first rotating shaft 15 is driven to rotate, which in turn drives the brush 901 to rotate. This allows the brush 901 to rotate while cleaning the spiral groove 301, enabling different brushes 901 to clean alternately. This changes the cleaning surface of the cleaning component 9 in contact with the spiral groove 301, thereby reducing wear on the cleaning component 9. In addition, when the brush 901 rotates, the tip of the brush 901 will lift the impurities inside the spiral groove 301 outward, which has a lifting effect, making it easier to discharge the impurities inside the spiral groove 301 and further improving the cleaning effect. In this technical solution, such as Figure 4 As shown, a scraper 45 is fixed to the surface of the fixing plate 8. The end of the scraper 45 is set with an arc surface structure, and the arc surface structure is in contact with the surface of the brush 901. When the brush 901 rotates around the first rotating shaft 15, when each group of brushes 901 rotates to the scraper 45, the scraper 45 can scrape off the impurities attached to the surface of the brush 901, thereby improving the cleanliness of the brush 901 and further improving the cleaning effect.

[0041] In Example 3, when the cleaning component 9 rotates around the first rotating shaft 15, although the cleaning component 9 uses multiple sets of brushes 901 to alternately clean the spiral groove 301, which can prevent the contact surface between the cleaning component 9 and the spiral groove 301 from remaining unchanged and reduce wear at the contact point, the position of each set of brushes 901 remains unchanged when cleaning the spiral groove 301. This results in a constant contact surface between each set of brushes 901 and the spiral groove 301, thereby increasing wear on the contact surface between the brushes 901 and the spiral groove 301. To address this problem, this example is an improvement based on Example 2. For details, please refer to Example 2. Figures 1-16 The end of the cleaning component 9 is fixed with a ring 21. The ring 21 is rotatably disposed in the first rotating shaft 15. Several sets of insertion holes 22 are opened on the ring 21. The fixing plate 8 is provided with an annular sliding groove 23. A sliding rod 24 is slidably disposed in the annular sliding groove 23. The end of the sliding rod 24 is elastically provided with a post 25 for inserting into the insertion hole 22. The end of the slide bar 24 is provided with a movable groove 26, and a slider 27 is slidably arranged in the movable groove 26. The insert post 25 is fixed on the lower surface of the slider 27. The inside of the slide bar 24 is provided with a lifting groove 28, and a lifting plate 29 is elastically arranged in the lifting groove 28. A sliding plate 30 is fixed on the surface of the slider 27, and the sliding plate 30 is slidably arranged in the lifting groove 28. A core rod 31 is slidably disposed inside the slide rod 24, and an abutment 32 is fixed at the end of the core rod 31. The abutment 32 is slidably disposed inside the slide rod 24, and an abutment rod 33 that abuts against the abutment 32 is fixed on the lower surface of the slide plate 30. The end of the slide bar 24 is fixed with a first limiting ball 34. The inside of the annular slide groove 23 is provided with a first track groove 35 for the first limiting ball 34 to slide. The first track groove 35 includes a first horizontal part 351, a first leftward part 352, a second horizontal part 353 and a first rightward part 354 that are connected in series. The end of the core rod 31 is fixed with a second limiting ball 36. The interior of the annular groove 23 is provided with a second track groove 37 for the second limiting ball 36 to slide. The second track groove 37 includes a third horizontal part 371, a second left-moving part 372, a fourth horizontal part 374, a third left-moving part 373, a second right-moving part 375, and a third right-moving part 376 that are connected together.

[0042] In this technical solution, when the first rotating shaft 15 drives the brush 901 to rotate, the first rotating shaft 15 drives the slide rod 24 to slide along the annular slide groove 23. The slide rod 24 drives the first limiting ball 34 to slide along the first horizontal part 351 of the first track groove 35. When the brush 901 rotates to... Figure 10 At point a, the first limiting ball 34 slides along the first leftward displacement portion 352, causing the first limiting ball 34 to drive the sliding rod 24 to move to the left. The sliding rod 24 moving to the left causes the slider 27 to move to the left, and the slider 27 causes the insertion post 25 to move to the left. At this time, the insertion post 25 is inserted into the insertion hole 22, causing the insertion post 25 to drive the ring 21 to rotate clockwise by a certain angle, causing the ring 21 to drive the brush 901 to rotate by a certain angle, until the first limiting ball 34 slides to the second horizontal portion 353. At this time, the brush 901 rotates to... Figure 10 At point b, the brush 901 stops rotating, which allows the brush 901 to change the contact surface between the brush 901 and the spiral groove 301 when cleaning the spiral groove 301 next time, thereby reducing the wear of the brush 901, increasing the service life of the brush 901, and further improving the cleaning effect. When the brush 901 changes its contact surface with the spiral groove 301 by rotating, the angle of the brush 901 cannot be adjusted by reversing its direction. This is because if reversing the direction is used, only a portion of the circumference of the brush 901 will contact the spiral groove 301, leaving uncontacted areas, thus reducing the effectiveness of the brush 901. To avoid this, the brush 901 should not be continuously rotating. If the brush 901 rotates while in contact with the spiral groove 301, it may carry impurities to the cleaned areas, resulting in incomplete cleaning. Therefore, in order to… This technical solution improves the contact between the circumferential surface of the brush 901 and the spiral groove 301, thereby enhancing the cleaning effect. In this process, as the brush 901 rotates from point a to point b, it rotates a certain angle and then its position is fixed. This allows the brush 901 to clean the spiral groove 301 without rotating, until the scraper 45 removes the impurities from the surface of the brush 901. Then, the fixing effect on the brush 901 is released until it rotates back to point a, allowing the brush 901 to continue rotating in the same direction at a certain angle, which can be between 30° and 45°. This ensures that the circumferential surface of the brush 901 can fully contact the spiral groove 301, thus improving the cleaning effect. The rotation process of the brush 901 is as follows: When the brush 901 rotates from point a to point b, it rotates a certain angle. During this process, the first limiting ball 34 slides along the first horizontal part 351 and the first leftward part 352, and the second limiting ball 36 slides along the third horizontal part 371 and the second leftward part 372, keeping the relative position of the core rod 31 and the slide rod 24 unchanged. Then, after the brush 901 rotates a certain angle, when the first limiting ball 34 slides along the third horizontal part 371, the second limiting ball... 36 first slides along the fourth horizontal section 374, maintaining the relative position of the core rod 31 and the slide rod 24 unchanged. At this time, the insertion post 25 is inserted into the insertion hole 22, so that the brush 901 will not rotate until the scraper 45 scrapes away the impurities on the surface of the brush 901. Then, the first limiting ball 34 continues to slide along the third horizontal section 371, and the second limiting ball 36 slides along the third leftward section 373, causing the second limiting ball 36 to drive the core rod 31 to move to the left. At this time, the core rod 31 moves to the left relative to the slide rod 24. Figure 15As shown, when the core rod 31 moves to the left, it drives the contact platform 32 to move to the left, causing the contact platform 32 to contact the contact rod 33, which in turn causes the contact rod 33 to move upward. The contact rod 33 drives the slide plate 30 to move upward, and the slide plate 30 drives the lifting plate 29 to move upward along the lifting groove 28. A first spring 42 is provided between the lifting plate 29 and the lifting groove 28. The upward movement of the lifting plate 29 compresses the first spring 42, causing the first spring 42 to store force. At the same time, the upward movement of the slide plate 30 drives the slider 27 to move upward, and the slider 27 drives the insertion post 25 to move upward, thus moving the insertion post 25 from... The insert is removed from the socket 22, and then the first limiting ball 34 slides along the first right-moving portion 354, causing the slide rod 24 to move to the right and reset. The second limiting ball 36 slides along the second right-moving portion 375. The core rod 31 and the slide rod 24 maintain their relative positions. At this time, since the insert 25 has been removed from the socket 22, the slide rod 24 will not cause the ring 21 to reverse when it moves to the right and reset. Then, the first limiting ball 34 slides back into the first horizontal portion 351, and the second limiting ball 36 slides along the third right-moving portion 376, causing the core rod 31 to move to the right relative to the slide rod 24, making... The core rod 31 drives the contact platform 32 to move to the right, and the contact rod 33 loses the contact of the contact platform 32. The first spring 42 releases its force, causing the slide plate 30 to drive the slider 27 to move downward. The slider 27 drives the insertion post 25 to move downward, inserting the insertion post 25 into the next insertion hole 22. At this time, the brush 901 rotates to point a again, completing one cycle. Through the above process, when the first rotating shaft 15 rotates and drives the slide rod 24 to slide along the annular groove 23, the slide rod 24 can perform left and right reciprocating motion. Each time the slide rod 24 performs a left and right reciprocating motion, it will drive the ring 21. Rotating a certain angle in one direction will not cause the ring 21 to rotate back and forth, thus preventing the brush 901 from rotating back and forth. This ensures that when the brush 901 cleans the spiral groove 301, it will rotate a certain angle in the same direction with each rotation, thereby changing the contact surface with the spiral groove 301. This avoids situations where the brush 901 cannot contact the spiral groove 301 in certain areas, which not only increases the full utilization of the brush 901 and reduces the occurrence of severe wear in certain areas, but also helps to improve the cleaning effect. In this technical solution, the movable groove 26 is provided so that the slider 27 can slide horizontally along the movable groove 26, and the insertion post 25 can move in an arc shape with the insertion hole 22, thus avoiding jamming.

[0043] In Example 4, when the cleaning component 9 cleans the spiral groove 301, some impurities may get stuck inside the spiral groove 301, making it difficult for the cleaning component 9 to remove the impurities. To address this problem, this example is an improvement based on Example 3. For details, please refer to [link / reference]. Figures 1-16The second retaining ring 7 is elastically provided with a striking post 38, and a sliding protrusion 39 is fixed on the surface of the striking post 38. A fixing ring 40 is fixed on the outer surface of the first retaining ring 6. The fixing ring 40 is slidably connected to the second retaining ring 7. A third track groove 41 for the sliding protrusion 39 to slide is opened on the surface of the fixing ring 40. The third track groove 41 includes multiple sets of energy storage parts 411 and striking parts 412 arranged in sequence.

[0044] In this technical solution, the end of the striking post 38 contacts the surface of the wire rope 3. The second retaining ring 7 has a contraction groove 44 for the striking post 38 to slide inside. A second spring 43 is provided between the contraction groove 44 and the striking post 38. When the second retaining ring 7 rotates, it drives the striking post 38 to rotate. The striking post 38 drives the sliding protrusion 39 to slide along the third track groove 41. When the sliding protrusion 39 slides along the power storage part 411, the striking post 38 moves into the contraction groove 44, compressing the second spring 43 and storing power. When the sliding protrusion 39 slides to the striking part 412, the sliding protrusion 39 loses its resistance, the second spring 43 releases its power, and the striking post 38 is released instantly, so that the striking post 38 strikes the surface of the wire rope 3, causing the surface of the wire rope 3 to vibrate. This facilitates the vibration and loosening of impurities inside the spiral groove 301, making it easier to remove impurities. In this technical solution, such as Figure 11 As shown, the striking post 38 is positioned in front of the cleaning component 9. The steel wire rope 3 is wound up in the direction of the arrow in the figure, so that after the striking post 38 strikes the steel wire rope 3, the cleaning component 9 cleans the impurities inside the spiral groove 301. The two work together to clean the impurities inside the spiral groove 301, resulting in a better cleaning effect.
