Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire rope replacement technology, and in particular to a wire rope replacement device for a rope reel. Background Technology
[0002] The wire rope on a crane is one of the core load-bearing and transmission components. During long-term use, it will gradually suffer from wear, broken wires, corrosion and fatigue damage due to repeated bending, friction, stretching and environmental influences, which will reduce its load-bearing capacity and safety performance. If it is not replaced in time, it can easily lead to wire rope failure or even breakage. Therefore, it needs to be replaced regularly to ensure the reliability of crane operation and operational safety.
[0003] Wire ropes are typically purchased in whole reels. When replacement is needed, maintenance personnel usually place the reel on the ground or a simple support, and with the help of multiple people or by using a lever to roll the reel, gradually pull out the required length of wire rope. Then, tools such as a cutting machine or wire rope shears are used to cut and replace it. However, this method has many drawbacks: First, the reel is heavy, resulting in high resistance when pulling manually and low dismantling efficiency; second, placing the reel directly on the ground or a simple support makes it prone to rolling or tipping over, lacking stable support; third, if the wire rope suddenly loosens or jams during pulling, it can easily cause injury to the operator; fourth, different specifications and sizes of reels often require temporary configuration or welding of supports, lacking versatility and adaptability; fifth, existing rotating trays have gaps, allowing dust, sand, and iron filings to easily enter the bearing, affecting user experience and bearing life. Utility Model Content

[0011] In some alternative embodiments, a gap is provided between the upper bearing slot and the lower bearing slot.
[0012] In some alternative embodiments, the rotary bearing assembly further includes a positioning element for quick positioning and connection of the tray.
[0013] In some alternative embodiments, the positioning element includes a screw and a nut. The screw passes through the bearing and the upper bearing slot in sequence along the central axis of the rotary bearing assembly and protrudes from the upper surface of the upper bearing slot. A mounting hole is provided at the center of the tray.

[0030] Please refer to Figures 1 to 3 As shown, this embodiment provides a wire rope replacement device for a rope reel, including a base 1, a rotary bearing assembly 2, and a tray 3. The rotary bearing assembly 2 includes a lower bearing slot 21, an upper bearing slot 22, a bearing 23, and a dustproof tube 24. The bottom end of the lower bearing slot 21 is fixed to the upper surface of the base 1. The bearing 23 is installed in the lower bearing slot 21 and can rotate around its central axis. The upper bearing slot 22 is opposite to the lower bearing slot 21 and is fixedly connected to the top of the bearing 23. The dustproof tube 24 is sleeved on the outside of the upper bearing slot 22 and the lower bearing slot 21, fixedly connected to the outside of the upper bearing slot 22, and rotates with it. The tray 3 is configured to carry the rope reel. The tray 3 is detachably and coaxially fixedly connected to the rotary bearing assembly 2 and can rotate around its axis. The diameter of the tray 3 is larger than the maximum diameter of the rope reel to be installed.
[0031] The tray 3 is coaxially and detachably fixedly connected to the rotating bearing assembly 2, and the tray 3 can rotate around its central axis. When disassembling the wire rope, operators do not need to move the heavy rope reel; they only need to rotate the tray 3 to loosen or wind the wire rope, effectively reducing the physical exertion of manual handling and improving disassembly efficiency. In addition, the coaxial rotating structure makes the disassembly process smoother and more stable, reducing pauses and repetitive operations. The upper bearing slot 22 and the lower bearing slot 21 form a stable support structure with the bearing 23. The dustproof tube 24 is sleeved on the outside of the upper bearing slot 22 and the lower bearing slot 21, which not only prevents dust, wire scraps, and other debris from entering the bearing 23 and affecting its rotation, ensuring smooth rotation of the bearing 23, but also provides a balancing support, making the rope reel less prone to shaking or tilting during disassembly and installation, ensuring operator safety, and extending service life. The diameter of the tray 3 is larger than the maximum diameter of the rope reel to be installed, which can support rope reels of different sizes without the need to replace the tray 3, improving the versatility and flexibility of the device and meeting the needs of different application scenarios.
[0032] For example, bearing 23 is a high-load bearing with a rated load of 50 tons, which can support the weight of heavy rope reels and wire ropes, and can withstand the dynamic load during long-term repeated rotation, load and operation, reducing the risk of premature wear or failure of bearing 23, ensuring stable and reliable rotation of pallet 3, and extending service life.
[0033] It is understood that the base 1 and the lower bearing slot 21 can be connected by welding, and this is not limited here. Both the base 1 and the tray 3 are made of steel plate. Steel plate has high strength and good load-bearing capacity, providing a stable and reliable foundation support, ensuring the durability of the overall structure of the tray 3 and the base 1. At the same time, steel plate is easy to cut, weld and process into the required shape (such as disc, square disc or other structures), the processing technology is mature and the cost is low. If both are cut into a disc structure, the force on the tray 3 is even when rotating, avoiding eccentric loads that cause shaking or tilting of the tray 3, which is suitable for cooperation with the rotary bearing assembly 2 to achieve smooth rotation and ensure smooth operation.
[0034] like Figure 3 As shown, specifically, both the upper bearing slot 22 and the lower bearing slot 21 are circular grooves, and the upper bearing slot 22 and the lower bearing slot 21 respectively fit the bearing 23 into the upper and lower parts of the bearing. The upper bearing slot 22 and the lower bearing slot 21 can tightly wrap the bearing 23, making it less likely for the bearing 23 to shift or wobble when the tray 3 rotates, thus improving the stability of the tray 3 rotation, making the bearing 23 evenly distributed, and reducing early wear or damage caused by localized stress concentration. In addition, the circular grooves provide natural geometric constraints, enabling the bearing 23 to be automatically positioned without the need for additional clamps or complex positioning devices.
[0035] More specifically, a gap is provided between the upper bearing slot 22 and the lower bearing slot 21.
[0036] When the tray 3 carries the rope coil or rotates, the bearing 23 is subjected to axial and radial loads. To avoid excessive axial pressure on the bearing 23, which could lead to wear, deformation, or increased rotational resistance, in some embodiments, a gap is provided between the upper bearing slot 22 and the lower bearing slot 21. This allows the bearing 23 to have slight axial movement during rotation or load-bearing, thereby buffering the load and protecting the bearing 23 and the structure of the tray 3. The gap may be, but is not limited to, between 3 mm and 7 mm.
[0037] To facilitate the rapid installation of the tray 3, in some embodiments, the rotary bearing assembly 2 also includes a positioning element 25 for quickly positioning the connected tray 3, reducing installation time and making the process of disassembling or replacing the rope reel more efficient.
[0038] Specifically, the positioning component 25 includes a screw and a nut. The screw passes through the bearing 23 and the upper bearing groove 22 in sequence along the central axis of the rotary bearing assembly 2, and protrudes from the upper surface of the upper bearing groove 22. A mounting hole is opened at the center of the tray 3. The screw passes through the mounting hole and is fixedly connected to the tray 3 by the nut, so that the tray 3 rotates synchronously with the bearing 23. The screw passes through the central axis of the rotary bearing assembly 2, and the center of the tray 3 is fitted onto the screw through the mounting hole and then fixed by the nut. The tray 3 is tightly connected to the bearing 23. The tray 3 will not be eccentric or wobble when rotating, which can ensure the smooth rotation of the tray 3. It is also convenient to install and disassemble. The operator only needs to tighten or loosen the nut to complete the installation or replacement of the tray 3, saving time and effort.
[0039] Combination Figure 1 and Figure 2 As shown, in some optional embodiments, multiple support beams 4 are arranged parallel to each other on the upper surface of the pallet 3 to support the rope reel. The distance between adjacent support beams 4 is greater than or equal to the width of the load-bearing part of the rope reel handling device. The support beams 4 on the pallet 3 directly bear the weight of the rope reel, effectively distributing the force and ensuring uniform stress on the bottom of the rope reel, thus guaranteeing the stability of the rope reel during rotation and handling. The distance between adjacent support beams 4 is greater than or equal to the width of the load-bearing part of the rope reel handling device, allowing the handling device to be directly inserted between the support beams 4 for hoisting or transfer, improving the compatibility between the handling device and the pallet 3 and increasing operational efficiency. It is understood that the support beams 4 can be, but are not limited to, channel steel. Channel steel itself has strong bending and compressive strength, providing sufficient support without easily deforming, and is readily available on the construction site.
[0040] In other embodiments, multiple support grooves that extend through the width of the pallet 3 are provided parallel to each other on the pallet 3 for carrying the rope reel. The distance between the edges of adjacent support grooves is greater than or equal to the width of the load-bearing part of the rope reel transporting device, thereby ensuring that the transporting device can be smoothly inserted into the pallet 3 for rope reel transfer or transport.
[0041] In some embodiments, limiting members 5 are symmetrically arranged on both sides of the central axis of the pallet 3. During the rotation of the pallet 3 or the handling of the rope reel, the radial movement of the rope reel can be effectively restricted, preventing it from swaying or sliding to the left or right, thereby avoiding excessive eccentric force, preventing the rope reel from falling off accidentally, improving operational safety, and reducing the risk of injury to operators.
[0042] like Figure 1 As shown, specifically, the limiting member 5 includes an L-shaped limiting protrusion, which includes a fixing part fixed to the pallet 3 and a limiting part extending radially along the pallet 3. The limiting part of the L-shaped protrusion extends radially along the pallet 3, directly blocking radial movement of the rope reel and effectively preventing the rope reel from swaying or sliding during pallet 3 rotation or handling. Its fixing part is fixed to the pallet 3, providing stable support, easy installation, and preventing loosening after fixing, thus improving the overall stability of the pallet 3 and significantly enhancing safety when rotating or handling heavy rope reels. Exemplarily, the fixing part is welded to the upper surface of the pallet 3.
[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
