Description

Technical Field

[0001] This utility model belongs to the field of crane equipment commissioning technology, and in particular relates to a wire rope quick winding and unwinding device. Background Technology

[0002] Wire ropes are regularly replaced components of lifting equipment. Under normal circumstances, the construction party will make auxiliary tools to replace the wire rope according to the equipment usage environment. There is no standardized device on the market for releasing and retracting old and new wire ropes.

[0003] The wire rope quick-release device is an essential tool for the commissioning, inspection and maintenance of lifting equipment. It is used to improve the safety, stability and reliability of the wire rope of the lifting equipment, and can improve the work efficiency when replacing the wire rope of the lifting equipment.

[0004] Taking the QB25 / 5t crane as an example, the main hook lifting height is 9m, and the main hook pulley ratio is 8. The main hook wire rope (model 20NAT6X19W+FC1670) is approximately 120m long. The previously common method was to pre-connect the old wire rope to a single synthetic fiber rope and then release the old rope. However, tying knots at the rope ends resulted in problems such as large cross-sectional area, easy detachment, easy jamming, and high risk. To improve the efficiency and reliability of wire rope replacement, after several improvements, a replacement method using welding between the old and new wire ropes was developed. This method is relatively simple, quick, easy to operate, saves manpower, and has good results. However, problems such as wire rope contamination, wear, and high labor intensity still exist.

[0040] Combination Figure 1-10 A wire rope rapid take-up and release device includes a chassis 1, a turntable 2, a guide device 3, and a take-up and release rope cage 4.

[0041] The turntable 2 is located on the upper part of the chassis 1 and is rotatably connected to the chassis 1. The guiding device 3 includes a guide pulley 3-1 for guiding the wire rope. The winding and unwinding cage 4 is fixed on the turntable 2 and is formed by connecting multiple tubes for winding and unwinding the wire rope. The winding and unwinding cage 4 forms a winding space inside and has an opening at the top. When unwinding the rope, the wire rope can be wound around the outside of the winding and unwinding cage 4. When winding the rope, the wire rope can be stored in the winding space through the opening.

[0042] Preferably, combined with Figure 2-4 The chassis 1 includes a base plate 1-1 (which may be made of iron plate). Multiple casters 1-2 are mounted on the bottom of the base plate 1-1. A bearing sleeve 1-3 is located in the center of the base plate 1-1. There are four casters 1-2 evenly distributed around the base plate 1-1, and they are connected to the base plate 1-1 via caster nuts 1-4 through holes drilled in the base plate. This design improves the chassis's maneuverability, preventing chassis wobbling caused by excessively rapid rotation of the wire rope coil; further protects the turntable, providing strong support; and enhances the flexibility of the device.

[0043] Preferably, combined with Figure 5-8 The turntable 2 includes a turntable body 2-1. A central bearing 2-6 is disposed at the bottom center of the turntable body 2-1, and the central bearing 2-6 is disposed within the bearing sleeve 1-3. A central rotating shaft 2-2 is disposed on the turntable body 2-1, and the bottom of the central rotating shaft 2-2 is connected to the central bearing 2-6. Multiple turntable casters 2-3 are disposed at the bottom of the turntable body 2-1, and the turntable casters 2-3 are connected to the turntable body 2-1 through turntable caster nuts 2-5. This design ensures smooth operation of the turntable during rotation and can simultaneously withstand axial force, radial force, and overturning moment, making it an ideal component for heavy loads and low speeds.

[0044] Preferably, there are four turntable casters 2-3, which are evenly distributed around the turntable body 2-1.

[0045] Preferably, the base plate 1-1 is square with dimensions of 1200mm × 1200mm, and the turntable body 2-1 is circular.

[0046] Preferably, combined with Figure 9 The guide device 3 is fixedly connected to the base plate 1-1. The bottom of the guide device 3 includes a telescopic rod 3-4, and the upper part includes a pulley mounting bracket 3-2. The guide pulley 3-1 and the pulley mounting bracket 3-2 are rotatably connected by bearings. The pulley mounting bracket 3-2 is provided with multiple height adjustment holes 3-3 for mounting the guide pulley 3-1. The pulley and the pin shaft can be adjusted up and down. The pulley can also be fixed in a designated position by a lock to realize the operation of different types of wire ropes. This structure can realize rope unloading under the combined action of wire rope tension, coiled wire rope weight and guide device.

[0047] Preferably, combined with Figure 10 The rope cage 4 is composed of multiple horizontal and vertical steel pipes connected together. The bottom diameter of the rope cage 4 is larger than the diameter of the top opening, forming a central section with the smallest diameter between the top and bottom. Figure 10 As shown, the lower diameter D = 950mm, the middle hole diameter D = 300mm, the upper opening diameter D = 500mm, and the overall height H = 1500mm; 12 steel pipes are evenly distributed around the perimeter for effective support. The rotating rope cage is made of Φ30mm steel pipe bent to ensure the overall structural balance; the large upper opening and small middle opening facilitate the insertion of the wire rope into the cage. After being inserted into the cage, the wire rope, under the action of gravity, assists in manually rotating the turntable to coil itself in the cage, preventing the wire rope from slipping out.

[0048] Preferably, combined with Figure 5 , 7 The turntable body 2-1 is provided with multiple sets of fixing bolt units along the circumference. Each set of fixing bolt units includes two fixing bolts 2-4 arranged radially. The steel pipe at the bottom of the rope cage 4 is arranged between the two fixing bolts 2-4 of each set of fixing bolt units.

[0049] This embodiment uses a QB25 / 5t crane as an example. The main hook lifting height is 9m, the main hook pulley ratio is 8, and the main hook wire rope (model 20NAT6X19W+FC1670) is approximately 120m long. Specific steps are as follows: Figure 13 As shown.

[0050] 1. Place the new wire rope on the wire rope winding device and move it under the crane. Run the crane to lower the hook smoothly and securely to the ground, keeping the hook pulley block upright. For cranes with helical or cam limit switches, these should also be released. When the remaining wire rope on the drum is one turn and the wire rope clamp bolt is in a position that facilitates releasing the wire rope, stop the crane. Use a rope clamp to secure the traction rope to one end of the wire rope on the drum. Use a wrench to loosen the clamp bolt on the drum at the end where the wire rope is secured, and manually pull the traction rope to lower the wire rope to the ground.

[0051] 2. Ground workers untie the old rope ends, use a grinder to smooth the ends of the new and old wire ropes, weld the ends of the new and old wire ropes together, use a grinder to smooth the sharp parts, and put on heat shrink tubing. This also serves as a marker and protection to prevent the wire rope from being worn when passing around the pulley block, and also makes it easier to observe the location of the connection point between the new and old wire ropes.

[0052] 3. Start the hoisting mechanism, using the old rope to drive the new rope, and wind the old rope onto the drum. (Combined with...) Figure 11 Stop the machine when the joint between the old and new ropes is wound onto the drum. Use a grinder to cut the joint between the old and new wire ropes (tie the end of the new rope before cutting to prevent it from coming apart). Use rope clamps to fix the traction rope and the new wire rope together, and temporarily fix the new rope to a suitable place on the trolley.

[0053] 4. Install the take-up / release rope cage 4 onto the turntable 2, and operate the crane to smoothly and orderly lower the old wire rope wound on the drum into the take-up / release rope cage 4. Figure 12 As shown, they were bundled and transported away.

[0054] 5. Unwind the remaining portion of the new wire rope. Use the traction rope to pull the other end of the new wire rope to the drum. At this point, both ends of the new wire rope are on the crane. Secure both ends of the wire rope to the first and third pressure plate bolts on the drum (the pressure plate bolts only press on one side). Operate the crane to rotate the drum until the wire rope is wound around the drum once, then stop. Secure the second pressure plate bolt, and then re-secure the first and third pressure plate bolts. The operator starts the hoisting mechanism, winds the new wire rope, and raises the hook. The entire replacement work is now complete.

[0055] This device is easy to operate, saves manpower, effectively reduces the workload of personnel, shortens replacement time, improves replacement efficiency and reliability, and effectively extends the service life of the wire rope. It can be widely applied to the replacement of wire ropes for other lifting equipment at launch sites.

[0056] Finally, it should be noted that the above description is only for illustrating the implementation of this utility model and is not intended to limit this utility model. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
