[0001] This utility model relates to the field of wear-resistant components, and more particularly to a wear-resistant component for material handling equipment. Background Technology

[0002] During material handling, equipment components such as conveyor belts, rollers, and slide rails are prone to wear due to long-term contact with materials. This wear not only reduces the service life of the equipment but also leads to a decrease in equipment operating efficiency and an increase in maintenance costs. These components are widely used in various material handling equipment, such as hook cranes, crushers, conveyors, loaders, and bulldozers.

[0003] Traditional anti-wear measures typically employ wear-resistant materials or surface coatings, such as welding, thermal spraying, and electroplating. However, material handling operations can cause severe wear on anti-wear components. Once the material or surface coating is worn, the entire component must be replaced, as it is not possible to quickly replace only locally worn areas. This results in long downtime and high maintenance costs. Therefore, an anti-wear component for material handling equipment is proposed to address these issues. Utility Model Content

[0029] 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.

[0030] Reference Figure 1 - Figure 2 The present invention provides an embodiment of an anti-wear component for material handling equipment, comprising a hook 1 and an anti-wear component 2. The hook 1 serves as the core load-bearing component, and the anti-wear component 2 includes a mounting block 101 and a screw 106. The top of the mounting block 101 is provided with a groove for placing the lifting rope. The anti-slip and wear-resistant material groove on the top of the mounting block 101 is specifically designed for the lifting rope to reduce friction and wear between the rope and the hook 1 during lifting. The material of the mounting block 101 is set to be anti-slip and wear-resistant.

[0031] Reference Figure 2 - Figure 4 The bottom of the mounting block 101 is fixedly connected to a positioning block 102. The cross-section of the positioning block 102 is set as a semi-circular shape. The bottom of the inner wall of the hook 1 is provided with a positioning groove that matches the shape of the positioning block 102. The semi-circular positioning block 102 at the bottom of the mounting block 101 and the positioning groove at the bottom of the hook 1 are precisely matched to achieve rapid positioning of the mounting block 101 and improve the installation accuracy of the mounting block 101.

[0032] Reference Figure 2 - Figure 4The bottom inner wall of the mounting block 101 is provided with a groove 104, and the bottom inner wall of the hook 1 is fixedly connected with a spring piece 103. The spring piece 103 is made of elastic metal material, and a protrusion 105 is provided in the middle of the spring piece 103. The protrusion 105 of the spring piece 103 contacts the inner wall of the groove 104. The number of spring pieces 103 is set to two sets. The side of the two sets of spring pieces 103 that are close to each other contacts the surface of the protrusion 109 to prevent the mounting block 101 from shifting under vibration or load and to provide a passive fastening function.

[0033] Reference Figure 2 - Figure 4 A block 108 is fixedly connected to the outer wall of the screw 106, and a protrusion 109 is fixedly connected to the outer wall of the block 108. A slot 110 is provided inside the hook 1, and the protrusion 109 is inserted into the inner wall of the slot 110. Nuts 107 are threadedly connected to both sides of the screw 106. The screw 106 is inserted into the slot 110 of the hook 1 through the block 108 and the protrusion 109. After the nuts 107 on both sides are rotated, they press against the outer wall of the hook 1, which facilitates the active application of fastening force. This forms a double lock with the passive fixing of the spring piece 103, ensuring the safety and stability of the mounting block 101 under heavy load.

[0034] Reference Figure 1 - Figure 3 The top of the hook 1 is fixedly connected to a mounting bracket 3. The top of the mounting bracket 3 is provided with a mounting groove. The top mounting bracket 3 provides a connection interface with the handling equipment. The mounting groove at the top facilitates the quick fixing of the entire device. The left side of the inner wall of the hook 1 is slidably connected to an anti-fall plate 4. The anti-fall plate 4 is elastically connected to the top of the inner wall of the hook 1 through a compression spring 5. The anti-fall plate 4 and the compression spring 5 form an anti-detachment mechanism. The spring force keeps the anti-fall plate 4 closed to prevent materials from slipping. The left side of the hook 1 is slidably connected to a positioning pin 6. The positioning pin 6 is used to lock the position of the anti-fall plate 4 to ensure safety during material handling.

[0035] Working principle: During use, the positioning block 102 cooperates with the positioning groove at the bottom of the inner wall of the hook 1 to achieve precise positioning of the anti-wear component 2. The protrusion 105 of the spring piece 103 contacts the groove 104 on the bottom inner wall of the mounting block 101. The screw 106 cooperates with the slot 110 inside the hook 1 through the square block 108 and the protrusion 109. After the square block 108 is inserted into the slot 110, the protrusion 109 on the surface of the square block 108 and the groove 104 on the inner wall of the mounting block 101 together squeeze the spring piece 103, so that the spring piece 103 cannot undergo elastic deformation, thereby firmly fixing the mounting block 101 on the hook 1. Then, the position of the screw 106 is fixed by the nut 107 to prevent the screw 106 from accidentally falling out of the hook 1 when the hook 1 is working, which further improves stability.

[0036] When materials need to be moved, the hoisting ropes with the materials tied to them are first placed in the placement slot of the placement block 101. The placement block 101 is made of non-slip and wear-resistant material to ensure the stable placement and wear resistance of the hoisting ropes. The anti-fall plate 4 is elastically connected to the top of the inner wall of the hook 1 through the compression spring 5 to prevent the hoisting ropes from accidentally falling off. The positioning pin 6 ensures the stable position of the anti-fall plate 4. The entire anti-wear assembly 2 effectively reduces the wear between the hoisting ropes and the hook 1 through the synergistic action of each component. When the wear of the placement block 101 is too severe and affects the safety of the material handling process, the placement block 101 can be quickly replaced by disassembling the screw 106 and the nut 107, thereby improving the service life and safety of the material handling equipment.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
