Embodiment Construction
[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0028] see Figure 1-5, the present invention provides a technical solution: a safety cradle for construction engineering, which is simple in operation and strong in practicability. A box door is installed, and the outer ring at the bottom of the bottom plate 1 is fixedly connected with concave blocks 3 at equal intervals. The number of concave blocks 3 is three, and both sides of the inner wall of the concave block 3 are connected with supporting leg rods 4 t...

Abstract
The invention discloses a safety cradle for construction engineering. The safety cradle comprises a bottom plate, and a top box is fixedly connected to the top of the bottom plate. In the safety cradle for construction engineering, a concave block, a threaded adjusting rod, a threaded ring, a connecting ring, a height adjusting rod, a round stopper, a bevel gear body and a bevel gear rod are usedto realize the rotation of support leg rods, thereby realizing the height change of the device. A height fixing hole, an adjusting handle and a fixed inserting rod control the change in the rotation of the bevel gear rod. A large transmission rod, a big gear, a small transmission rod, a pinion, a transmission gear and a chain realize the different rotation modes of a drum. A big handle, a large plunger, a large jack, a small handle, a small plunger and a small jack control the rotation of the large transmission rod and the small transmission rod, respectively. A convex groove, a convex block,an arc clamp block, a compression spring and a pressure plate facilitate the reversal of the drum. And a chute, a clamping block body, a corner sliding rod and a hydraulic telescopic rod realize the main movement of a draw rope, which is convenient for the unloading of an unloading barrel.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to a safety cradle for construction engineering. Background technique [0002] Manual digging has the advantages of low cost and no restrictions on the construction site. It is still widely used in construction projects. Manual digging piles are usually in groups of two, one person digs in the pile hole, and the other excavates the excavated soil on the upper part of the ground. Lifting and dumping are generally carried out with a cradle. The cradle generally includes a triangular support frame and a drum set on the support frame. A rope is wound on the drum, a safety hook is set at one end of the rope, and a mud bucket filled with soil Hang by the safety hook and then turn the drum to lift, but the existing cradle cannot adjust the height of the triangular support frame according to the actual situation. During the process of lifting the bucket by the crank handle...
