Three-point lifting equipment for large castings

Abstract

The invention discloses three-point lifting equipment for large castings. The three-point lifting equipment comprises a center base frame provided with a lifting base in middle; the side edge of the center base frame is connected with three cross beam frames uniformly distributed and flatly extending outwards; a row of positioning holes is uniformly distributed in the cross beam frames; lifting hook rods downwards dropping are connected by pin shafts through the positioning holes; hook parts flatly extending inwards are arranged at the lower end parts of the lifting hook rods; the center base frame is a short cylinder; a lifting base with a lifting ring is arranged in the center position of the upper surface of the center base frame; the cross beam frames flatly extending outwards are integrally produced on the peripheral wall surface of the center base frame; U-shaped grooves capable of being embedded in bodies of the cross beam frames from the lower parts are formed in the upper end parts of the lifting hook rods; transverse shaft holes are formed in the U-shaped grooves; and the pin shafts penetrate through the transverse shaft holes and the corresponding positioning holes in the cross beam frames to vertically fix the lifting hook rods on the bodies of the cross beam frames. The three-point lifting equipment has such characteristics as simple structure, convenience for use, safety, reliability, capability of reducing labor intensity and reduction of lifting cost.

Description

technical field [0001] The invention relates to a three-point hoisting device for large castings, and belongs to the technical field of casting special hoisting. Background technique [0002] Large castings are heavy, occupy a large area, and most of them are in a high-temperature state. Therefore, there are certain difficulties in lifting such castings. First, it requires a large spreader; The hoisting equipment including cranes and gantry cranes do not meet the hoisting requirements of large castings because the supporting hoisting tools do not meet the hoisting requirements of large castings. Therefore, there are high labor intensity, high hoisting costs, and certain potential safety hazards. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a three-point hoisting device for large castings with simple structure, convenient use, safety and reliability, which can reduce labor intensity and...
