Description

Technical Field

[0001] The utility model relates to the technical field of steel wire rope winding, in particular to a steel wire rope winding device for a tower crane. Background Art

[0002] Wire rope winding refers to the process of winding, storing or storing wire rope in a certain way and method. Winding is an important step in the production, use, maintenance or transportation of wire rope. During the operation of tower crane equipment, the wire rope needs to be constantly tightened and relaxed for hoisting operations. When tower crane equipment is operating, a tower crane wire rope winding device is usually required.

[0003] For example, the Chinese patent with announcement number CN220684507U discloses a wire rope winding device for tower crane, which has solved the problem that when the rope is wound, the winding roller can only wind the rope in one position. Therefore, this may cause a large number of ropes to be repeatedly wound together, and the friction generated between them may cause the rope to break. After further searching, it was found that a self-controlled wire rope winding device with a rainproof structure for tower crane disclosed by announcement number CN213623039U has a specific technical structure setting to effectively solve the technical disadvantages of lack of rainproof mechanism during use, resulting in serious corrosion of the winding device, and inconvenience in removing rainwater on the wire rope, which reduces the service life of the wire rope. However, in actual use, wire rope winding devices for tower cranes with similar structures still have many defects.

[0004] The existing technology has the following problems:

[0005] For example, it is not convenient to automatically clean and lubricate the wound wire rope. Dirt and liquid accumulation are easy to occur on the wire rope during long-term use, which can easily cause the wire rope to be misaligned or rusted during winding. It is also not convenient to limit the winding speed of the device. Emergency braking cannot be performed when the wire rope breaks suddenly, which can easily cause safety accidents.

The mounting frame 1 can provide an installation position for some parts of the device, the driving motor 12 can drive the winding drum 13 to rotate so as to wind up the wire rope, the rope arrangement structure 4 can continuously adjust the horizontal position of the wire rope to be wound up during the winding process, so that the wire rope can be evenly wound up on the outer wall of the winding drum 13, the sliding rod 11 can provide an installation position for the cleaning structure 2, and the cleaning structure 2 can slide horizontally on its outer side as the position of the wire rope changes, the cleaning structure 2 can clean and lubricate the wire rope during the winding process, to avoid dirt and liquid accumulation during the long-term use of the wire rope, and to prevent it from being dislocated or rusted during the winding process.

[0027] like Figure 2 and Figure 3As shown, the cleaning structure 2 includes a cleaning shell 21, the inner wall of the top right side of the cleaning shell 21 is slidably connected to the outer wall of the slide bar 11, and a winding opening is opened in the middle of the left and right sides of the cleaning shell 21. A mounting rod is rotatably installed on the right part of the inner cavity of the cleaning shell 21, and a roller 22 is fixedly installed in the middle of the outer wall of the mounting rod. A gear set 23 is fixedly installed on the top of the roller 22. The gear set 23 is composed of two bevel gears meshing vertically. The bottom end of the bevel gear at the bottom is fixedly connected to the top end of the roller 22, and the left end of the bevel gear at the left part is fixedly installed with a transmission rod. The left part of the inner cavity of the cleaning shell 21 is fixedly installed with a mounting rod. The slot plate 25, the left end of the transmission rod is rotatably connected to the top rear position of the right end of the mounting slot plate 25, the driving gear 24 is fixedly installed on the outer wall of the left part of the transmission rod, and the transmission assembly 26 is rotatably installed on the right side of the mounting slot plate 25. The transmission assembly 26 includes a mounting snap ring 261, the left part of the mounting snap ring 261 is rotatably installed on the inner side of the mounting slot plate 25, and the right part of the mounting snap ring 261 is fixedly installed with a driven gear 262, and the rear position of the top of the driven gear 262 is meshed with the front position of the bottom of the driving gear 24, and a plurality of cleaning brush strips 27 are fixedly installed in a ring-shaped manner on the inner side of the driven gear 262. The cleaning shell 21 and the mounting groove plate 25 can provide installation positions for some parts. When the wire rope passes through the cleaning shell 21 from the two winding ports and slides, the displacement of the wire rope can drive the roller 22 to rotate in the horizontal direction, thereby driving the driving gear 24 to rotate in the vertical direction through the gear set 23. The driving gear 24 can drive multiple cleaning brush strips 27 to rotate in the vertical direction through the transmission assembly 26, thereby rotating and cleaning the displaced wire rope.

[0028] like Figure 2 As shown, the bottom of the cleaning housing 21 is linearly arranged with a plurality of drainage grooves 28. The displacement and winding of the wire rope can drive the cleaning housing 21 to vibrate slightly, so that the dirt dropped during the cleaning process can be discharged to the outside through the drainage grooves 28.

[0029] like Figure 2 and Figure 4 As shown, a sponge 29 is fixedly installed at the top left of the inner cavity of the cleaning shell 21, and the sponge 29 is located at the left side of the mounting slot plate 25. An oil storage tank 210 is fixedly installed at the left side of the top of the cleaning shell 21.

The lower parts of the two oil guide rods 211 respectively penetrate the bottom of the oil storage tank 210 and the top of the cleaning shell 21 to the inside of the front and rear sides of the sponge 29. When the wire rope passes through the cleaning shell 21 during the winding process, the oil guide rod 211 can absorb the grease inside the oil storage tank 210 and absorb it into the sponge 29 through osmotic pressure transmission, so that the sponge 29 can apply lubricating grease to its surface during the friction process with the outer wall of the wire rope, so as to automatically maintain the wire rope during the winding process to prevent it from rusting.

[0030] like Figure 5 and Figure 6 As shown, the speed limiting structure 3 includes a rotating seat 31, the bottom end of the rotating seat 31 is fixedly connected to the top end of the front part of the mounting frame 1, the winding drum 13 includes a brake shaft rod 131, the rear end of the brake shaft rod 131 is fixedly connected to the axis center of the front end of the winding drum 13, and the front part of the outer wall of the brake shaft rod 131 is rotatably connected to the rear part of the inner wall of the rotating seat 31, and the front part of the inner wall of the rotating seat 31 is annularly distributed and fixedly installed with multiple speed limiting grooves 32, a connecting column 33 is fixedly installed at the middle position of the front end of the brake shaft rod 131, a spring 34 is fixedly installed on the right side of the outer wall of the connecting column 33, and a connecting rod is fixedly installed on the right part of the spring 34, two brake blocks 35 are symmetrically rotatably installed on the left and right sides of the front end of the brake shaft rod 131, the top of the brake block 35 on the right side is fixedly connected to the right part of the connecting rod, and the bottom of the two brake blocks 35 are rotatably installed with a connecting plate 36 together. The rotating seat 31 and the brake shaft 131 can provide installation positions for some components. When the device is abnormal or the wire rope breaks, causing the speed of the winding drum 13 to be too fast, the centrifugal force of the two brake blocks 35 can force it to rotate outward. When the hook parts of the two brake blocks 35 are displaced to the edge of the inner cavity of the rotating seat 31, the two brake blocks 35 can be stuck on the inner side of the speed limiting groove 32, thereby limiting the rotation of the brake shaft 131 and forcing the winding drum 13 to stop rotating to avoid safety accidents. When the speed limiting structure 3 is in the unlocked state, the spring 34 can limit the brake block 35 on the right side, and drive the brake block 35 on the left side to limit synchronously through the connecting plate 36, so as to prevent the brake block 35 from being displaced due to its own gravity and causing the speed limiting structure 3 to enter the locked state.

[0031] like Figure 1 and Figure 7As shown, the rope-laying structure 4 includes a rope-laying frame 41, the left end of which is fixedly connected to the right bottom end of the front part of the mounting frame 1, two limit rods 42 are fixedly installed at the upper and lower positions on the inner side of the rope-laying frame 41, and a rope-laying wheel assembly 43 is slidably installed on the outer walls of the two limit rods 42 together, and a driving motor 2 44 is fixedly installed at the rear end position of the top of the rope-laying frame 41, a screw rod 45 is rotatably installed on the inner side of the left part of the top of the rope-laying frame 41, and the outer wall of the screw rod 45 is threadedly connected to the left side of the top of the rope-laying wheel assembly 43, and the output end of the driving motor 2 44 passes through the right part of the top of the rope-laying frame 41 and is fixedly connected to the rear end of the screw rod 45. The rope rack 41 can provide an installation position for some components. When the device is reeled in, the driving motor 44 can drive the rope wheel assembly 43 to move in the horizontal direction through the screw rod 45. The two limit rods 42 can limit the movement posture of the rope wheel assembly 43 so that it always maintains horizontal displacement and does not rotate. The rope wheel assembly 43 can guide and limit the wire rope. The rope wheel assembly 43 can drive the wire rope to move in the horizontal direction during the displacement process, so that the wire rope can be evenly distributed on the outer wall of the winding drum 13 during the winding process.

[0032] The working principle of the utility model is as follows: when the winding starts, the driving motor 12 can drive the winding drum 13 to rotate so as to wind up the wire rope. The rope arrangement structure 4 can continuously adjust the horizontal position of the wire rope to be wound up during the winding process, so that the wire rope can be evenly wound up on the outer wall of the winding drum 13. The sliding rod 11 can provide an installation position for the cleaning structure 2, and the cleaning structure 2 can slide horizontally on its outer side as the position of the wire rope changes. The cleaning structure 2 can be cleaned and lubricated during the winding process of the wire rope to avoid dirt and liquid accumulation during the long-term use of the wire rope, and cause it to be misplaced or rusted during the winding process. The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model.
