Description

Technical Field

[0001] The invention relates to the technical field of steel wire rope products, in particular to a universally detachable rope core. Background Art

[0002] Grommet Slings (hereinafter referred to as Grommet Slings) are a type of wire rope sling made by first folding one end of the wire rope back into a loop, and then wrapping the other end through it six times. After the six turns are completed, the exposed end is inserted from the starting end of the wire rope into the core, and the original rope core is replaced from the starting end, so that both ends of the rope are inside the loop, each occupying half. This process is called core replacement (making the end of the wire rope invisible from the outside).

[0003] In actual production, in order to adapt to large-scale production, a complete substitute rope core is often used. After the winding is completed, the rope ends at both ends are pressed in respectively to completely replace the substitute rope core. There are currently two main types of replacement cores. One is to use a steel pipe of a fixed length to form a circle, wind the wire rope around the outside of the steel pipe, and then along the gap of the rope strands, insert the two ends of the wire rope into the core of six turns respectively to replace the steel pipe; the other is to use the wire rope core. In order to adapt to the needs of equipment rotation, a complete rope core that is thicker than the rope loop wire rope is also used. No matter which of the above methods, the rope core is a consumable and will be scrapped after a few uses. Not only is the production efficiency low, but the manufacturing cost is also very high.

[0004] Therefore, it is urgent to design a universal detachable rope core to solve the above problems. Summary of the Invention

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The present invention provides a universal detachable rope core, comprising a chain link assembly, wherein a plurality of chain link assemblies are provided, and two adjacent chain link assemblies are detachably connected, and the chain link assembly comprises:

[0028] Chain link body 1;

[0029] Connector end: one end of the link body 1 is fixedly connected to the connector end;

[0030] A connecting female end is provided at the other end of the link body 1 , and the connecting female end is adapted to the connecting sub-end. The connecting sub-end of one link body 1 is detachably connected to the connecting female end of the adjacent link body 1 .

[0031] Furthermore, the connecting sub-end includes a ball head 2, a bulb 7 is fixed to the top of the link body 1, the ball head 2 is fixed to the top of the bulb 7, a section 6 is provided on the ball head 2, and there are two sections 6. The two sections 6 are symmetrically arranged about the axis of the ball head 2. The link body 1 is detachably connected to the connecting female end of the adjacent link body 1 through the ball head 2 and the bulb 7.

[0032] Furthermore, the ball head 2 is a hemispherical structure, the arc surface of the ball head 2 is fixedly connected to the bulb 7, and the horizontal surface of the ball head 2 is perpendicular to the bulb 7.

[0033] Furthermore, the connecting female end includes a groove 3, a notch 5 and a lower hole 4. A lower hole 4 is provided at the end of the link body 1 away from the ball head 2. The diameter of the lower hole 4 is larger than the diameter of the bulb 7, so that the bulb 7 can swing within a certain range. The groove 3 is opened in the link body 1. The groove 3 is arranged on the side of the lower hole 4 close to the ball head 2. The groove 3 is connected to the lower hole 4. The notch 5 is opened on the side wall of the link body 1. The groove 3 and the lower hole 4 are both connected to the notch 5. The ball head 2 enters and exits the groove 3 through the notch 5 and is detachably connected to the groove 3.

[0034] Furthermore, the groove 3 is composed of a cylindrical structure and a hemispherical structure. The cylindrical structure is located on a side close to the ball head 2 , and the hemispherical structure is located on a side away from the ball head 2 .

[0035] The present invention uses a groove 3 composed of a cylindrical structure and a hemispherical structure, and a ball head 2 and a bulb 7 that match the hemispherical structure, so that when two adjacent chain link components are connected, a ball hinge structure is formed, which can rotate and swing in multiple directions. When in use, the pulley passes very smoothly, and the core replacement process is more flexible and convenient.

[0036] Furthermore, the notch 5 consists of two parts. The distance between the notch 5 near the ball head 2 is adapted to the distance between the two cut surfaces 6 , and the distance between the notch 5 away from the ball head 2 is adapted to the diameter of the bulb 7 .

[0037] The structure of the notch 5 adopts the above-mentioned direction setting, and cooperates with the ball head 2 and the bulb 7 with the cut surface 6. When disassembling the rope core, it is necessary to put the rope core in the unacceptable state, and the horizontal surface of the ball head 2 on one link assembly is flush with the horizontal surface of the groove 3 of the other link assembly. Disassembly and assembly can only be carried out when the cut surface 6 is parallel to the notch 5. In the natural state and working state, the two adjacent link assemblies cannot be disassembled and assembled, which is safer to use. At the same time, the structure is simple and disassembly and assembly are more convenient.

[0038] Furthermore, an annular groove 8 is formed on the top outer wall of the link body 1 .

[0039] The chain link body 1 is provided with an annular groove 8, so that any section on the rope core can use a universal rope clamp to fix the wire rope end. At the same time, the annular groove 8 provided on the chain link body 1 can also play a role in reducing weight.

[0040] Instructions for use: According to the diameter of the rope loop to be wound, several chain link assemblies are used to assemble the required rope core. According to actual conditions, rope clamps are installed on the chain link body 1, and the rope loop is wound. After the wire rope is wound around the rope core, the rope loop needs to be removed from the equipment and replaced. The rope core replacement process is similar to the existing steel pipe core or steel wire rope core replacement process. The difference is that when using the rope core of the present invention, for a rope core that is too long, since the two adjacent chain link assemblies are detachably connected and a ball hinge connection structure is formed at the connection between the two adjacent chain link bodies 1, it can be replaced and disassembled at the same time, and the ball hinge structure can rotate and swing, so the rope core replacement is smoother, and the replaced rope cores are all the same rope segment, which is more convenient to store and manage after cleaning, and the rope core composed of several chain link assemblies can be reused many times. When a chain link assembly is damaged, only the chain link assembly needs to be replaced, which makes the overall production cost of the rope loop lower.

[0041] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0042] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
