AI Technical Summary

Technical Problem

When the existing casting lifting devices are lifting heavier weight or larger castings, the clamping pliers are easily loosened, causing the casting to slide down and the clamping pliers cannot be automatically opened or closed, which is labor-intensive.

Method used

The clamping pliers are adopted with cross-setting, combined with the design of automatic telescopic parts, lifting ropes and diamond four-link links. The clamping pliers are opened or closed by the telescopic parts, and the clamping is maintained by using the tension of the lifting ropes to improve clamping stability with the air bag and pulley structure.

Benefits of technology

Automatic casting lifting is realized, which improves clamping stability and safety, reduces manpower consumption, adapts to the clamping needs of castings of different sizes, and prevents slipping during the lifting process.

Abstract

The invention discloses a hoisting device and method for casting production. The hoisting device comprises a hoisting plate, two clamping pincers and an automatic telescopic piece, and two sets of inserting claws are arranged at the bottoms of the two clamping pincers in a staggered mode; two pulleys are connected below the lifting plate in a left-right sliding mode, the top ends of the clamping pincers are each fixedly connected with a set of lifting ropes, and the two sets of lifting ropes are crossed, then bypass the pulleys in the opposite side directions and are connected with the inserting claws; a rectangular ring is arranged at the crossed position of the lifting ropes, the upper end of the rectangular ring is connected with an automatic telescopic piece, a rhombic four-bar linkage is hinged to the lower end of the rectangular ring, and the left and right sides of the rhombic four-bar linkage are hinged to power arms of the clamping pincers; through the arrangement of the automatic telescopic piece, the lifting plate, the clamping pincers, the pulley, the inserting claw, the rectangular ring and the lifting rope, the automatic telescopic piece stretches out and draws back up and down, the two clamping pincers can be driven to be opened or closed through the rhombic four-bar linkage, and therefore a casting is automatically clamped or released, and time and labor are saved; in addition, through coordination and cooperation of a lifting rope, a rhombic four-bar linkage and an inserting claw, the clamping effect on the casting is improved.
