Safety shaking frame for constructional engineering

Abstract

The invention relates to a safety shaking frame for constructional engineering. The safety shaking frame comprises a support frame and a revolving drum. The revolving drum is connected with a driving mechanism. A safety rope and a safety hook are arranged on the revolving drum. First gears are arranged at two ends of the revolving drum. A transmission shaft is arranged on the lower side of the revolving drum. Second gears are arranged at two ends of the transmission shaft. Each first gear is connected with the corresponding second gear via a chain. A worm gear is arranged in the middle of the transmission shaft. A worm is arranged on the lower side of the worm gear. A revolving handle is arranged at one end of the worm. A lug is arranged at the other end of the worm. A non-return pin is arranged on the lateral side of the lug and mounted on the upper side of a support table of a mounting seat, and one end of the non-return pin is connected with a third hinge of the mounting set. The safety shaking frame for constructional engineering has the advantages that according to the technical scheme, the non-return pin cooperates with the lug, the worm is prevented from revolving clockwise, falling of a mud bucket is prevented, and safety accidents are avoided.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a safety cradle for construction engineering. Background technique [0002] Manual excavation of piles has the advantages of low cost and no restrictions on construction sites, and is still widely used in construction projects. Manual excavation of piles is generally done in groups of two, one person digs in the pile hole, and the other person lifts and dumps the excavated soil on the upper part of the ground. The lifting is generally operated by a cradle. The cradle generally includes a triangular support frame and a drum set on the support frame. A safety rope is wound on the drum, and one end of the safety rope is provided with a safety hook. The mud bucket with soil is hung by the safety hook and then the drum is rotated to lift . The traditional support frame is integrally welded by steel, the shape cannot be changed, its weight and volume are large, and manual hand...

AI Technical Summary

Problems solved by technology

The traditional support frame is integrally welded by steel, its shape cannot be changed, its weight and volume are large, and it is inconvenient to manually move and stack.

In addition, the traditional cradle is generally equipped with a rotating handle at one end of the drum. When operating, people need to turn the handle from one end of the cradle, which will easily make the cradle unbalanced. When the mud bucket is lifted to the pile hole, one hand needs to hold Hold the handle to prevent the drum from reversing, hold the mud bucket with the other hand, and then remove the mud bucket with both hands

In this mode of operation, the posture of the construction workers is extremely awkward, and the hands holding the mud bucket or the rotating drum are easy to slip off, causing the mud in the mud bucket to shake out, or the mud bucket to fall, causing safety accidents, especially when the pile hole diameter is large. , the extension length of the arm is limited
