Description

Technical Field

[0001] The invention belongs to the field of ergonomics, and in particular relates to a lifting device which is convenient for loading, unloading and picking. Background Art

[0002] At present, when workers put the materials placed in layers into the fixed device, they need to bend down from the second layer to pick up the materials at a lower height. As the number of layers decreases, the depth of the workers' bending increases as the height of the materials is reduced. Due to the accumulation of bending times in a single day, the damage to the workers' bodies is imaginable. This design will make up for this deficiency by changing the height of the material placement device, so as to achieve the purpose of reducing the labor intensity of the operators. Summary of the invention

[0020] The fixing plate 3 is arranged at the bottom, and side plates are arranged on both sides of the fixing plate 3, and a lower rail 5 is fixed on each side plate. A bearing seat 1 is arranged in the middle of the fixing plate 3, and a screw rod 2 is installed on the bearing seat. The screw rod 2 is arranged parallel to the lower rail 5. A nut rod 4 is arranged between the screw rod 2 and the lower rail 5, and the nut rod 4 is arranged to be able to move horizontally on the lower rail 5;

[0021] The movable plate 7 is arranged above the fixed plate 3, and side plates are arranged downward on both sides of the movable plate 7, and upper slide rails 8 are fixed on the side plates;

[0022] The support frame 6 is a long plate-shaped structure with a hole in the middle. There are two groups of support frames 6, which are respectively arranged on the left and right sides of the fixed plate 3. The two support frames 6 in each group are arranged crosswise with each other, one of which is connected to the nut rod 4 at the bottom and placed in the lower slide rail 5, and the top is fixed to the end of the upper slide rail 8, and the other is fixed to the end of the lower slide rail 5 at the bottom and the top is placed in the upper slide rail 8. A support rod 11 is passed through the four support frames 4;

[0023] The position of the nut rod 4 is adjusted by rotating the screw rod 2, driving the nut rod 4 to slide along the lower rail 5. The crossing angle of each group of support frames 6 is changed by adjusting the position of the nut rod 4. The support frame 6 opens and closes with the support rod 11 as a fulcrum, driving the movable plate 7 to rise or fall in height.
