Safety cradle for construction engineering

Abstract

The invention relates to a safety cradle for construction engineering. The safety cradle for the construction engineering comprises a supporting frame, and a rotating drum which is connected with a driving mechanism, wherein a safety rope and a safety hook are arranged on the rotating drum; first gears are arranged at two ends of the rotating drum; a transmission shaft of which two ends are provided with second gears is arranged at the lower side of the rotating drum; the first gears and the second gears are connected through chains; a worm gear is arranged in the middle part of the transmission shaft, and a worm is arranged at the lower side of the worm gear; one end of the worm is provided with a rotating handle while the other end of the worm is provided with a lug; a non-return pin is arranged beside the lug and is mounted at the upper side of the supporting table board of a mounting seat; one end of the non-return pin is connected with the mounting seat in a third hinging manner. According to the abovementioned technical scheme, the safety cradle for the construction engineering has the advantage that the non-return pin and the lug are matched with each other to prevent the worm from clockwise rotating as well as preventing a concrete barrel from sudden falling off, thus avoiding safety accident.

Description

[0001] The present invention is a divisional application of an invention patent with an application date of January 23, 2015, an application number of 2015100369487, and an invention title of "a safety cradle for construction engineering". technical field [0002] The invention relates to the field of construction engineering, in particular to a safety cradle for construction engineering. Background technique [0003] Manual excavation of piles has the advantages of low cost and no restrictions on construction sites, and is still widely used in construction projects. Manually excavating piles is generally in a group of two people, one person excavates in the pile hole, and one person lifts and dumps the excavated soil on the upper part of the ground, and the lifting generally uses a cradle for operation. The cradle generally includes a triangular support frame and a rotating drum set on the supporting frame. A safety rope is wound on the rotating drum, and a safety hook is s...

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
