Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a crane with anti-rope tangling function. Background Technology

[0002] Cranes with anti-rope entanglement function refer to lifting equipment that, based on traditional cranes, integrates a special anti-rope entanglement mechanism to prevent key ropes such as hoisting ropes, luffing ropes, and slewing ropes from becoming entangled, knotted, or stacked out of order during winding, operation, or work. Through mechanical constraints, dynamic guidance, or intelligent control, it ensures that the ropes always move in an orderly manner along a preset trajectory, fundamentally reducing safety risks such as equipment failure and load falls caused by rope entanglement, while improving work efficiency.

[0003] The winding and unwinding of the wire rope on the drum drives the lifting and lowering of the hook. Its anti-winding device moves laterally in sync with the rotation of the drum. Through mechanical guidance, the wire rope is accurately guided into the rope groove of the drum, forcing the wire rope to wind neatly layer by layer, avoiding the problems of tangled rope and rope jamming caused by crossing and stacking, ensuring smooth winding and unwinding of the wire rope and improving the safety of operation.

[0004] In the prior art, some equipment's anti-rope tangling mechanism is not fitted onto the drum, but rather slides the rope guide inside the drum's outer shell. This can cause the wire rope to deviate or sway due to factors such as tension fluctuations and load swing, making it easy for the wire rope to break free from the rope guide's constraint, resulting in jumping or tangling. Therefore, a crane with anti-rope tangling function is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a crane with an anti-rope tangling function, which aims to improve the problem that the anti-rope tangling function of some cranes easily causes the wire rope to break free from the rope guide constraint.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A crane with anti-rope tangling function includes a gantry frame, an anti-rope tangling mechanism is provided inside the gantry frame, a sliding plate is slidably connected inside the gantry frame, a self-lubricating mechanism is fixedly connected to the front side of the sliding plate, and a slide rail is fixedly connected inside the gantry frame.

[0008] The anti-tangle rope mechanism includes a housing, inside which a drum is rotatably connected, and outside the drum are multiple annular clamps slidably connected. A connecting plate is fixedly connected to one side of each annular clamp, and outside each annular clamp is multiple connecting blocks. Outside each connecting block is a curved plate, and inside the curved plate is a limit component.

[0009] As a further description of the above technical solution:

[0010] The limiting assembly includes a rope groove, the connecting plate is internally threaded with bolts, the outer shell is fixedly connected with a limiting rod, and each limiting rod is fixedly connected with two limiting blocks.

[0011] As a further description of the above technical solution:

[0012] The rope groove is formed inside the anti-curved plate, and the outside of the drum is fixedly connected to the inside of the portal frame;

[0014] The self-lubricating mechanism includes a connecting block, a round cover fixedly connected to the top of the connecting block, a ball bearing slidably connected inside the connecting block, an oil storage groove opened inside the connecting block, an oil storage component fixedly connected to the top of the sliding plate, and multiple protrusions fixedly connected to the top of each slide rail.

[0015] As a further description of the above technical solution:

[0016] The oil storage assembly includes an oil storage box, a protective shell is fixedly connected to the front side of the oil storage box, and an oil delivery pipe is fixedly connected inside the protective shell.

[0022] A steel wire rope is fixedly connected to the outside of the drum, and a hook is slidably connected to the outside of the steel wire rope.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by placing the annular clamp on the outside of the drum and tightening the bolts inside the two contacting connecting plates, the bolts tighten the two connecting plates on the adjacent side, so that the annular clamp fits against the outside of the drum. Then, by adjusting the bolts on the outside of the anti-curved plate, the anti-curved plate and the connecting block are adjusted to a suitable height. When the wire rope is started to be wound up, the anti-curved plate will guide the wire rope into the guide groove of the drum, preventing the wire rope from being piled up messily during winding and unwinding.

[0025] 2. In this utility model, the sliding plate drives the connecting block to move, thereby causing the connecting block to drive the ball to slide on the protrusion. When the bottom of the connecting block moves to the top of the protrusion, it will push the ball into the inside of the oil storage tank, thereby causing the lubricating fluid stored in the oil storage tank to flow out, achieving the effect of lubricating the slide rail and preventing the sliding plate from getting stuck or not smooth when sliding on the slide rail.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a crane with an anti-rope entanglement function, comprising a gantry frame 1. The gantry frame 1 serves as an integral load-bearing frame, providing an installation base for components such as the anti-rope entanglement mechanism 2 and the sliding plate 3. The anti-rope entanglement mechanism 2 is provided inside the gantry frame 1 to constrain the arrangement trajectory of the wire rope 7 to prevent entanglement. The sliding plate 3 is slidably connected inside the gantry frame 1 and can move laterally along the slide rail 5 to drive the lifting device to adjust the working position. A self-lubricating mechanism 4 is fixedly connected to the front side of the sliding plate 3 to reduce frictional loss between the sliding plate 3 and the slide rail 5 and ensure smooth movement. The slide rail 5 is fixedly connected inside the gantry frame 1 to provide a guide trajectory for the sliding plate 3 and ensure its stable movement.

[0035] The anti-winding mechanism 2 includes a housing 21, which serves as a protective and support shell for the anti-winding mechanism 2, preventing external dust and debris from interfering with the movement of the rope. Inside the housing 21, a drum 22 is rotatably connected. The drum 22 is driven to rotate by a drive motor to realize the winding and unwinding of the wire rope 7. Multiple annular clamps 23 are slidably connected to the outside of the drum 22. The annular clamps 23 can slide along the axial direction of the drum 22, and their inner side is in contact with the surface of the drum 22. The annular structure forms a circumferential constraint on the wire rope 7 to prevent the wire rope 7 from bulging or shifting locally. A connecting plate 24 is fixedly connected to the adjacent side of the multiple annular clamps 23, and the connecting plate 24 connects the multiple annular clamps 23 in series into a whole.

[0036] By synchronously driving all the annular ties 23 to move along the axial direction of the drum 22, multiple connecting blocks 25 are fixedly connected to the outside of the multiple annular ties 23. The connecting blocks 25 connect the annular ties 23 and the anti-curved plate 26 into one unit, so that the anti-curved plate 26 moves synchronously with the annular ties 23. The anti-curved plate 26 is fixedly connected to the outside of the connecting blocks 25. The anti-curved plate 26 adopts an arc-shaped bending structure, and forms lateral guidance for the wire rope 7 through curved surface contact, correcting the sway caused by uneven tension of the rope. Limiting components 27 are opened inside the anti-curved plate 26.

[0037] The limiting component 27 includes a rope groove 271, which is formed inside the inverted plate 26. The groove width is adapted to the diameter of the wire rope 7. The groove confines the wire rope 7 within a preset path, preventing it from detaching from the guide of the inverted plate 26. The connecting plate 24 is internally threaded with bolts 272. By rotating the bolts 272, the spacing between adjacent annular clamps 23 can be adjusted, thereby adapting to drums 22 of different diameters and ensuring the constraint of the annular clamps 23 on the rope. The outer casing 21 is externally fixedly connected to... The limiting rod 273 extends axially along the drum 22 and is slidably connected to the connecting plate 24, providing guidance for the movement of the connecting plate 24 and the annular tie 23 and preventing them from shifting laterally. Two limiting blocks 274 are fixedly connected to the outside of the limiting rod 273. The two limiting blocks 274 are located at corresponding positions at both ends of the drum 22. By blocking the movement range of the anti-curved plate 26, the sliding of the annular tie 23 is limited, preventing it from exceeding the effective winding area of ​​the drum 22 and causing the rope to overflow.

[0038] Reference Figure 3 and Figure 4 The self-lubricating mechanism 4 is used to reduce frictional loss between the sliding plate 3 and the slide rail 5. It achieves long-term stable lubrication by automatically replenishing lubricating oil. The connecting block 41 is fixed on the front side of the sliding plate 3, integrating components such as the ball bearing 43 and the oil reservoir 44 into one unit, and moves synchronously with the sliding plate 3. A round cover 42 is fixedly connected to the top of the connecting block 41. The round cover 42 adopts a dustproof and sealing design and is fastened to the top of the connecting block 41 to prevent external dust and debris from entering the oil reservoir 44 and contaminating the lubricating fluid. At the same time, it avoids the lubricating fluid from splashing due to vibration. The ball bearing 43 is slidably connected inside the connecting block 41. The bottom contacts the surface of the slide rail 5. Rolling friction replaces sliding friction, which greatly reduces the resistance when the sliding plate 3 moves.

[0039] The connecting block 41 has an oil reservoir 44 inside, which is located above the ball bearing 43. The oil reservoir 44 stores special lubricant and releases grease through the squeezing action of the ball bearing 43 to provide lubrication for the contact surface between the ball bearing 43 and the slide rail 5. The top of the sliding plate 3 is fixedly connected to an oil storage component 46, which serves as a source of lubricant and continuously supplies grease to the oil reservoir 44. The top of each slide rail 5 is fixedly connected to multiple protrusions 45, which are evenly distributed along the length of the slide rail 5 and are slightly higher than the surface of the slide rail 5. These protrusions are used to trigger the squeezing action of the ball bearing 43 to release the lubricant.

[0040] The oil storage assembly 46 is used to store sufficient lubricating oil and achieve precise replenishment. It includes an oil storage box 461, which is a sealed container. A protective shell 462 is fixedly connected to the front of the oil storage box 461. The protective shell 462 is made of high-strength plastic or metal and covers the connection between the oil delivery pipe 463 and the oil storage box 461 to prevent the oil delivery pipe 463 from falling off or being damaged due to vibration or collision. The oil delivery pipe 463 is fixedly connected inside the protective shell 462. The oil delivery pipe 463 is a flexible oil-resistant hose. One end is connected to the oil outlet at the bottom of the oil storage box 461, and the other end is connected to the oil storage tank 44 of the connecting block 41. The lubricating grease is transported from the oil storage box 461 to the oil storage tank 44 by gravity or a small amount of pressure to achieve automatic oil replenishment.

[0041] Reference Figures 2 to 4 The rope groove 271 is formed inside the inverted plate 26. The groove shape of the rope groove 271 matches the diameter of the wire rope 7. When the wire rope 7 is wound up or down, the physical constraint of the rope groove 271 confines the wire rope 7 within a preset trajectory, preventing it from detaching from the guide of the inverted plate 26 due to external disturbances. The outside of the drum 22 is fixedly connected to the inside of the portal frame 1 through a bearing seat. The portal frame 1 provides support for the drum 22, ensuring that the drum 22 does not deflect radially when subjected to the tension of the wire rope 7. Through the stable rotation of the drum 22 and the guiding constraint of the rope groove 271, the anti-winding effect of the wire rope 7 being orderly wound along the spiral path of the drum 22 is achieved.

[0042] The bottom of the sliding plate 3 is slidably connected to the outside of the slide rail 5. The contact surface between the bottom of the sliding plate 3 and the slide rail 5 is precision machined. When the drive mechanism moves the sliding plate 3, the slide rail 5 restricts the movement direction of the sliding plate 3 through linear guidance to ensure that it moves smoothly along a straight line and avoids jamming caused by lateral deviation. The oil storage box 461 and the connecting block 41 are connected through the oil supply pipe 463. The lubricating fluid in the oil storage box 461 is continuously transported to the oil storage tank 44 of the connecting block 41 through the oil supply pipe 463 under the action of gravity. Through the sliding linkage between the sliding plate 3 and the slide rail 5 and the continuous oil replenishment by the oil supply pipe 463, the self-lubricating mechanism 4 achieves the effect of replenishing grease to the friction surface in real time and reducing wear.

[0043] The ball bearing 43 is externally slidably connected to the inside of the oil reservoir 44. The ball bearing 43 can slide up and down along the inner wall of the oil reservoir 44. When the sliding plate 3 drives the connecting block 41 to move to the protrusion 45, the protrusion 45 lifts the ball bearing 43, causing it to slide upward in the oil reservoir 44 and squeeze the internal lubricant, causing the lubricant to seep out from the gap between the ball bearing 43 and the oil reservoir 44. The other end of the oil delivery pipe 463 is fixedly connected to the inside of the round cover 42. The round cover 42 provides a sealing interface for the oil delivery pipe 463 to prevent lubricant leakage or impurities from entering. At the same time, the oil delivery pipe 463 is connected to the oil reservoir 44 through the round cover 42. When the grease in the oil reservoir 44 decreases, the oil delivery pipe 463 will immediately replenish the grease. Through the sliding and squeezing of the ball bearing 43 in the oil reservoir 44 and the sealing and replenishing of the oil delivery pipe 463, the effect of releasing the grease on demand and continuous lubrication is achieved.

[0044] A steel wire rope 7 is fixedly connected to the outside of the drum 22. One end of the steel wire rope 7 is fixed to the drum 22 through a rope clamp or wedge joint. When the drive motor drives the drum 22 to rotate in both directions, the drum 22 drives the steel wire rope 7 to be wound and unwound through surface friction and tension at the fixed end, thereby realizing the lifting and lowering of the hook 6.

[0045] Working principle: When it is necessary to retract the wire rope 7, first remove the bolts 272 of the two connecting plates 24, then pass the annular clamp 23 through the rope groove 271 on the outside of the drum 22 and put the annular clamp 23 on the outside of the drum 22. After passing the wire rope 7 through the rope groove 271, use a screwdriver to tighten the bolts 272 inside the two contacting connecting plates 24, so that the bolts 272 tighten the two connecting plates 24 on the adjacent side, until there is no gap between the inner wall of the annular clamp 23 and the outside of the drum 22, so that the annular clamp 23 is retracted. The tie 23 is attached to the outside of the drum 22. Then, by adjusting the bolts 272 on the outside of the anti-curved plate 26, the anti-curved plate 26 and the connecting block 25 are adjusted to a suitable height. When the wire rope 7 is started to be wound up, the anti-curved plate 26 will guide the wire rope 7 into the guide groove of the drum 22 to prevent the wire rope 7 from being piled up messily during winding and unwinding. Because the upper and lower ends of the anti-curved plate 26 are anti-curved, the limiting rod 273 and the limiting block 274 on the outside of the outer shell 21 can limit the anti-curved plate 26 when it slides to prevent the anti-curved plate 26 from deviating excessively.

[0046] When the device slides, the sliding plate 3 drives the connecting block 41 to move together, so that the connecting block 41 drives the ball bearing 43 to slide on the protrusion 45. When the bottom of the connecting block 41 moves to the top of the protrusion 45, it will push the ball bearing 43 into the oil storage tank 44, thereby causing the lubricant stored in the oil storage tank 44 to flow out, achieving the effect of lubricating the slide rail 5 and preventing the sliding plate 3 from getting stuck when sliding on the slide rail 5. When the oil level in the oil storage tank 44 is insufficient, the oil storage box 461 will deliver lubricant to the oil storage tank 44 through the oil supply pipe 463.
