[0029] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0030] Cable reel, also known as cable reel or wire reel, is a device used to store and manage cables, ropes or hoses. It is widely used in the storage, rotation and transportation of wires and cables, especially in wire drawing machines, stranding machines, electricity, communications, railways, construction sites and other occasions.

[0031] Cable reels are classified into large and small types according to their diameter. Large cable reels have a diameter of more than 1 meter, and some even reach more than 5 meters. They are mostly made of wood and are used in large-scale transportation, logistics and other occasions. Small cable reels have a diameter between 30cm and 100cm. Typical representatives are cable reels made of thermoplastic polymer materials (ABS) and high-temperature resistant materials, which are suitable for families or small projects. Cable reels are classified into plastic cable reels, wooden cable reels, metal cable reels, etc. According to the material, plastic cable reels are light, easy to manufacture, and low in cost, and are suitable for the storage and rotation of small cables. Wooden cable reels are often used for the transportation and packaging of large cables, and have high load-bearing capacity and stability. Metal cable reels, such as aluminum cable reels and copper cable reels, have good electrical conductivity and mechanical strength, and are suitable for use in complex environments, but are relatively expensive and heavy.

[0032] The existing cable drum includes a cylindrical reel and two side plates respectively arranged at both ends of the reel. The reel is used to wind the cable or rope. When the cable drum needs to be transported, the fixing rope is passed through the reel to lift or fix it. However, during transportation, vibration and shaking will cause friction between the fixing rope and the contact surface of the cable drum, causing damage to the paint surface of the cable drum and affecting the service life of the cable drum.

[0033] In view of this, the present application provides a protective sleeve for a cable drum and a cable drum fixing device. By setting a first lining plate and a second lining plate, an isolation layer is set on the fixing rope, the cable drum and the end face of the cable drum. When the fixing rope passes through the shaft hole to be fixed to the cable drum, the protective sleeve of the cable drum avoids direct contact and friction between the fixing rope and the cable drum, thereby preventing damage to the paint surface of the cable drum due to direct contact between the two, thereby improving the life and reliability of the cable drum.

[0034] Combine the following Figure 1 A protective bushing for a cable drum according to an embodiment of the first aspect of the present application is described.

[0035] refer to Figure 1 The protective bushing of the cable drum of this embodiment is used for winding cables. The cable drum is provided with an axial hole. The protective bushing includes a first lining plate 100 and at least one second lining plate 200, wherein the first lining plate 100 is arranged in the axial hole and supported on the inner wall of the axial hole and fits with the inside of the axial hole. In this way, the first lining plate 100 sets an isolation layer between the fixing rope and the cable drum, thereby preventing the fixing rope from directly rubbing against the inside of the cable drum when passing through the axial hole.

[0036] The second lining plate 200 is arranged at the axial end of the first lining plate 100 along the axial direction of the shaft hole. The second lining plate 200 is suitable for abutting against the axial end face of the cable drum. The second lining plate 200 forms a protective plate on the end face of the cable drum to avoid direct contact and friction between the end face of the cable drum and the fixing rope due to vibration and shaking during transportation.

[0037] It can be seen that by arranging the first lining plate 100 and the second lining plate 200, an isolation layer is provided on the fixing rope, the cable drum and the end surface of the cable drum. When the fixing rope passes through the shaft hole to be fixed to the cable drum, the protective sleeve of the cable drum avoids direct contact and friction between the fixing rope and the cable drum, thereby preventing damage to the paint surface of the cable drum caused by direct contact between the two, thereby improving the life and reliability of the cable drum.

[0038] Exemplarily, the material of the first lining plate 100 and the second lining plate 200 can be a polymer material, a rubber material, a polyurethane (PU) material, or a mixture of any two or more of the above-mentioned example materials, to ensure good wear resistance, corrosion resistance and aging resistance, etc., without limitation herein.

[0039] In some embodiments, the first lining plate 100 and the second lining plate 200 are integrally formed, thus ensuring that the protective sleeve can work together as a whole when subjected to external forces to jointly resist complex working conditions such as vibration, shaking and impact. In addition, the manufacturing process is simplified and production efficiency is improved.

[0040] In some embodiments, in combination Figure 1The first lining plate 100 is parallel to the axis of the shaft hole, so that the first lining plate 100 and the cable drum are more closely fitted, and the protection of the cable drum by the first lining plate 100 is strengthened, and the deformation or damage of the shaft hole caused by vibration and shaking during transportation or use is prevented. It can also play a role of isolation and friction reduction through direct contact with the fixed rope, and protect the paint surface or metal surface of the inner wall of the shaft hole from wear. The second lining plate 200 is perpendicular to the axis of the shaft hole, so that the second lining plate 200 is closely abutted against the end face of the cable drum along the axial direction, and the end face of the cable drum is prevented from being damaged by impact or friction during transportation. In addition, the second lining plate 200 also provides a certain protection area for the cable drum, and enhances the protection effect of the cable drum.

[0041] In some embodiments, in combination Figure 1 A reinforcing rib 300 is provided at the connection between the first lining plate 100 and the second lining plate 200. The reinforcing rib 300 is located on the side surface of the protective bushing facing away from the cable drum.

[0042] The reinforcing rib 300 increases the rigidity and strength of the connection between the first lining plate 100 and the second lining plate 200, and reduces the possibility of deformation or breakage when an external force acts on it. When the fixing rope is used to tie or hoist the cable drum, the reinforcing rib 300 can help the protective bushing to disperse the stress, reduce the occurrence of stress concentration, help to extend the service life of the protective bushing, and prevent local damage caused by stress concentration.

[0043] In some embodiments, the first lining plate 100, the second lining plate 200 and the reinforcing rib 300 are integrally formed. For example, the three can be combined into one by injection molding, pressing, etc., to ensure the overall installation reliability.

[0044] In some embodiments, the reinforcing rib 300 protrudes from the side surface of the inner wall of the first lining plate 100 that is away from the axial hole, so that the reinforcing rib 300 directly supports the area of ​​the first lining plate 100 around the axial hole. When the cable drum rotates or is subjected to axial force, the reinforcing rib 300 can resist deformation to ensure that the first lining plate 100 maintains a stable shape and position. In addition, the protrusion of the reinforcing rib 300 can also reduce the friction area between the fixing rope and the first lining plate 100 to a certain extent, reduce wear, and protect the first lining plate 100.

[0045] In some embodiments, the reinforcing rib 300 protrudes from the surface of the second lining plate 200 on the side facing away from the cable drum, thereby strengthening the supporting structure of the second lining plate 200. During transportation, when the cable drum is subjected to impact or pressure, the reinforcing rib 300 can provide additional support to prevent the second lining plate 200 from deformation or damage. In addition, the reinforcing rib 300 also increases the contact area and friction between the sleeve and the external environment, such as packaging boxes, fixtures, etc., thereby improving the stability of the protective sleeve of the cable drum.

[0046] It can be seen that the design position of the reinforcing rib 300 can be adjusted according to actual needs and is not limited here.

[0047] In some embodiments, in combination Figure 1 The outer contour of the cross section of the reinforcing rib 300 is an arc shape. The arc-shaped cross section can smoothly transition the connection between the rib and the lining body, avoiding the stress concentration phenomenon that may be caused by sharp corners. When subjected to external force, the arc-shaped cross section can better disperse the stress and reduce the risk of local damage. In addition, the arc-shaped cross section has good stability and can enhance the bearing capacity of the rib. When subjected to pressure or impact, the reinforcing rib 300 can better resist deformation and maintain the overall structural strength of the protective sleeve of the cable drum.

[0048] In some embodiments, in combination Figure 1 A buffer portion 110 is provided at least partially toward the center of the shaft hole of the first liner 100, and an elastic member 400 is provided at the buffer portion 110. Both ends of the elastic member 400 are respectively provided at the end portions of the buffer portion 110, and the elastic member 400 and the buffer portion 110 jointly form a buffer cavity.

[0049] The buffer portion 110 is a supporting structure for the elastic member 400 and provides a buffer cavity to accommodate and limit the deformation of the elastic member 400. When the fixing rope is used to bundle or hoist the cable drum, the elastic member 400 is deformed and absorbs energy, thereby reducing the damage of the fixing rope to the first lining plate 100. In addition, the elastic member 400 can also restore its original shape to provide a buffer for the next impact.

[0050] In this way, by providing the buffer portion 110 and the elastic member 400, the buffering capacity of the protective sleeve of the cable drum in the shaft hole area is improved, which helps to improve the protection of the cable drum by the protective sleeve of the cable drum. In addition, the deformation and recovery process of the elastic member 400 can absorb and disperse the impact energy, thereby reducing the damage of the fixing rope to the lining.

[0051] In some embodiments, in combination Figure 1 The first lining plate 100 is also provided with a limiting part 120, and there are two limiting parts 120, which are respectively arranged on both sides of the buffer part 110 along the circumference of the shaft hole. When the fixing rope is fixed on the first lining plate 100, it contacts the elastic member 400. The two limiting parts 120 are respectively located on both sides of the buffer part 110 along the circumference of the shaft hole, and limit the fixing rope. When the fixing rope is subjected to external force or vibration, its movement range will be limited between the two limiting parts 120, preventing the fixing rope from excessive movement or falling off.

[0052] Thus, by limiting the movement of the fixing rope, the limiting portion 120 also reduces the friction and wear between the fixing rope and the first lining plate 100, prolongs the service life of the protective bushing of the cable drum, and also reduces the noise and vibration generated by wear.

[0053] Exemplarily, the buffer portion 110 and the limiting portion 120 may be disposed near the center of the first lining plate 100 .

[0054] In some embodiments, the first lining plate 100 is an arc plate or an annular plate. Taking the arc plate as an example, Figure 1 The cable drum is usually designed to be cylindrical. Designing the first lining plate 100 as an arc-shaped plate or an annular plate can better adapt to the shape of the cable drum. This design can ensure that the first lining plate 100 fits well with the cable drum to improve the stability and protective effect of the protective sleeve of the cable drum. In addition, the arc-shaped or annular first lining plate 100 can better adapt to the shape of the cable drum, thereby effectively limiting the displacement and shaking of the cable drum, helping to improve the stability of the cable drum when rotating and impacted, and reducing the possibility of accidents.

[0055] In some embodiments, the second lining plate 200 is an arc plate or an annular plate. Taking the arc plate as an example, Figure 1 Designing the second lining plate 200 as an arc-shaped plate or an annular plate can enhance its supporting capacity for the cable drum, increase the contact area between the bushing and the cable drum, improve the supporting force, and reduce the vibration and noise that may be generated when the cable drum rotates.

[0056] In some embodiments, in combination Figure 1 The protective bushing of the cable drum includes a first bushing 500 and a second bushing 600 which are arranged axially opposite to each other along the shaft hole. Thus, when the fixing rope is fixed on the protective bushing, the arrangement of the first bushing 500 and the second bushing 600 enables both sides of the cable drum to be evenly supported and protected. The first bushing 500 and the second bushing 600 both include a first lining plate 100 and a second lining plate 200. Thus, more contact points and supporting surfaces are provided between the fixing rope and the protective bushing, which helps to disperse pressure and reduce wear.

[0057] When the fixing rope is binding the cable drum, the fixing rope contacts the first bushing 500 and the second bushing 600 respectively, and the fixing rope fixes the first bushing 500 and the second bushing 600 on the cable drum, preventing the bushings from shifting or falling off when the cable drum rotates or is impacted, thereby ensuring that the bushings can provide support and protection for the cable drum. In addition, the binding force of the fixing rope is evenly transmitted to both ends of the cable drum through the first bushing 500 and the second bushing 600, and the pressure dispersion reduces the situation where the cable drum is subjected to excessive local force, reduces the risk of wear and damage, and ensures the safety and reliability of the protective bushing of the cable drum during use.

[0058] On the other hand, the cable drum fixing device of the embodiment of the present application, by providing the protective bushing of the cable drum in the above-mentioned embodiment, provides an isolation layer on the fixing rope, the cable drum and the end surface of the cable drum. When the fixing rope passes through the axial hole to be fixed to the cable drum, the protective bushing of the cable drum avoids direct contact and friction between the fixing rope and the cable drum, thereby preventing damage to the paint surface of the cable drum due to direct contact between the two, thereby improving the life and reliability of the cable drum.
