Problems solved by technology

[0002] Steel wire rope joints are usually casted with metal (such as zinc) or resin glue, but each has its own disadvantages: although metal casting is used for high strength after molding, the melting point of the metal used for casting is relatively high. For example, the melting point of zinc is about 420°C. Casting equipment and environmental requirements are high, and it is not suitable for on-site casting; although resin glue casting can achieve normal temperature operation and has low requirements for personnel and equipment, its mechanical properties are not high after curing and its properties are relatively brittle. Fragile when subjected to shock loads, insufficient reliability

Abstract

The invention discloses a socket casting agent. The socket casting agent comprises a liquid component and a solid component, wherein the liquid component comprises unsaturated polyester resin and an accelerant; the solid component includes a powder reinforcement and an initiator. The liquid component and the solid component are prepared separately and are stored in respective containers separately. When in use, the liquid component and the solid component are fully stirred and uniformly mixed according to the proportion, and are cast into a socket within the gelation time. The casting agent provided by the invention can be operated at normal temperature, has good mechanical properties after being cured and molded, is tightly combined with a rope, has strong clamping force and is suitable for a hoisting or anchoring device at the end of the rope.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a casting agent for steel wire rope knots. Background technique [0002] Steel wire rope joints are usually casted with metal (such as zinc) or resin glue, but each has its own disadvantages: although metal casting is used for high strength after molding, the melting point of the metal used for casting is relatively high. For example, the melting point of zinc is about 420°C. Casting equipment and environmental requirements are high, and it is not suitable for on-site casting; although resin glue casting can achieve normal temperature operation and has low requirements for personnel and equipment, its mechanical properties are not high after curing and its properties are relatively brittle. Fragile when subjected to shock loads and lacks reliability. [0003] To sum up, how to provide a socket casting agent with high mechanical properties and operability at room tempe...
