DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0024] Referring to Figures 1-4 , the hoisting device for mechanical engineering comprises: a lifting ring 1, screw holes 11 are formed in the middle of both sides of the lifting ring 1, screw rods 12 are threadedly connected in the two groups of screw holes 11, first clamping teeth 13 are rotatably installed on the outer sides of the two groups of screw rods 12, and a reinforcing mechanism is installed on the outer wall of the lifting ring 1;

[0025] The reinforcing mechanism comprises a piston pipe 2 fixedly installed at the middle of both ends of the lifting ring 1, a piston rod 21 movably installed inside both sets of piston pipes 2, a second clamping tooth 22 fixedly installed outside both sets of piston rods 21, a lifting rope 23 fixedly installed inside both sets of piston rods 21, a lifting piece 24 fixedly installed on the other side of both sets of lifting ropes 23, and a connecting hole 25 formed in the middle of the lifting piece 24. The two sets of screw holes 11 are symmetrically arranged at the center of the lifting ring 1, and the two sets of piston pipes 2 are symmetrically arranged at the center of the lifting ring 1, so as to ensure that the two sets of first clamping teeth 13 and the second clamping teeth 22 are distributed on the four sides of the material barrel. By pulling the two sets of second clamping teeth 22 of the reinforcing mechanism, the inner walls of the two sets of second clamping teeth 22 are attached to the top of the material barrel, and the lifting piece 24 in the middle of the lifting ring 1 is pulled up by the crane. As the lifting piece 24 continuously rises, the lifting ropes 23 on both sides of the lifting piece 24 are continuously stretched, and the piston rods 21 fixedly installed with the two sets of lifting ropes 23 are synchronously stretched along the piston pipe 2, so as to ensure that the larger the mass of the material cylinder is, the greater the tension of the lifting ropes 23 on both sides of the lifting piece 24 is, and the two sets of second clamping teeth 22 fixedly installed with the two sets of lifting ropes 23 can firmly lock the material cylinder, thereby preventing the material cylinder from falling during lifting.

[0026] Further, the lifting ring 1 is fixedly installed with a fixing piece 31 at each corner of the outer wall, four sets of steel wires 32 are fixedly installed on the four sets of fixing pieces 31, a resisting ring 33 is fixedly installed at one end of each of the four sets of steel wires 32, the resisting ring 33 corresponds to the lifting piece 24, the firmness of the lifting ring 1 is increased, a fixing piece 36 is fixedly installed at the other end of each of the four sets of steel wires 32, and the four sets of fixing pieces 36 are fixedly installed with a base plate 34. A placing groove 35 is formed in the middle of the base plate 34. When the lifting piece 24 is lifted by the crane outside, the lifting piece 24 will first pull the two sets of lifting ropes 23, so that the two sets of second clamping teeth 22 continuously clamp the top of the material barrel. When the lifting ropes 23 are continuously stretched, the resisting rings 33 at the top of the four sets of steel wires 32 will support the top of the lifting piece 24, and the base plate 34 fixedly installed at the other end of the four sets of steel wires 32 can support the bottom of the material barrel, so as to ensure the stability and firmness of the material barrel during lifting, prevent the material barrel from shaking and falling during lifting, and greatly improve the safety of the device.

[0027] Further, a handle 14 is fixedly installed at the other side of each of the two sets of screw rods 12, and a knob rod is fixedly installed at the two sides of each handle 14, so as to facilitate the operator to rotate the screw rod 12. When the operator twists the handle 14, the screw rod 12 can be rotated, and the distance between the two sets of first clamping teeth 13 can be adjusted.

[0028] Further, the first clamping teeth 13 and the second clamping teeth 22 are both in L-shaped cross section, and the inner sides of the first clamping teeth 13 and the second clamping teeth 22 are arc-shaped, thereby increasing the clamping force of the clamping teeth. When the plurality of groups of first clamping teeth 13 and second clamping teeth 22 are distributed at the four corners of the top of the material barrel, the cooperating clamping teeth are in L-shaped cross section, and the inner sides are arc-shaped, thereby firmly clamping the top of the material barrel.

[0029] Further, the outer walls of the two groups of piston rods 21 are both sleeved with springs 3, and the two sides of each group of springs 3 are fixedly installed with the outer walls of the piston pipes 2 and the second clamping teeth 22, thereby supporting the piston rods 21. When the crane does not hoist the lifting piece 24, the two groups of second clamping teeth 22 can clamp the top of the material barrel under the pulling force of the springs 3.

[0030] In use, the lifting ring 1 is first butted with the top of the material barrel to be hoisted, and the two groups of threaded rods 12 are screwed into the two groups of screw holes 11, so that the first clamping teeth 13 installed on one side of the two groups of threaded rods 12 are butted with the two sides of the top of the material barrel and firmly clamp the column. At the same time, the two groups of second clamping teeth 22 of the reinforcing mechanism are pulled, and the inner walls of the two groups of second clamping teeth 22 are attached to the top of the material barrel. Then, the crane pulls the lifting piece 24 in the middle of the lifting ring 1. As the lifting piece 24 continuously rises, the lifting ropes 23 on both sides of the lifting piece 24 are continuously stretched, and the piston rods 21 fixedly installed with the two groups of lifting ropes 23 are synchronously stretched along the piston pipes 2, thereby ensuring that the greater the mass of the material barrel, the greater the pulling force of the lifting ropes 23 on both sides of the lifting piece 24, so that the second clamping teeth 22 fixedly installed with the two groups of lifting ropes 23 can firmly lock the material barrel, thereby preventing the material barrel from falling during hoisting. At the same time, the four groups of fixed members 31 are fixedly installed with the steel wires 32, and the other ends of the four groups of steel wires 32 are fixedly installed with the outer wall of the lifting piece 24. When the crane hoists the lifting piece 24, the lifting piece 24 will first pull the two groups of lifting ropes 23, so that the two groups of second clamping teeth 22 continuously clamp the top of the material barrel. When the lifting ropes 23 are continuously stretched, the top supporting rings 33 of the four groups of steel wires 32 are supported on the top of the lifting piece 24, and the bottom plates 34 fixedly installed at the other ends of the four groups of steel wires 32 can support the bottom of the material barrel, thereby ensuring the stability and firmness of the material barrel during hoisting, preventing the material barrel from shaking and falling during hoisting, and greatly improving the safety of the device.

[0031] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
