Embodiment Construction
[0011] Shown in Fig. 1, the present invention is made up of frame bar 1, pole 3, and frame plate 2 etc. As shown in Fig. 2, Fig. 3 and Fig. 4, two slanted holes are arranged on the frame plate 2, and the side of the frame plate 2 is provided with two symmetrical lugs 5 which are welded or cast as a whole, and the center of the lug 5 is Has a shaft hole. The two rack rods 1 pass through the two oblique holes on the rack disc 2 respectively, and protrude from above the rack disc 2 respectively. The upper end of the strut 3 is provided with a shaft hole, and the end is embedded between the two lugs 5, and the bolt 4 is fixed with a nut after passing through the lug 5 and the shaft hole at the upper end of the strut 3. After the above installation, the three points where the two poles 1 and the poles 3 contact the ground form three vertices of an isosceles or equilateral triangle, thereby enhancing the stability of the support. During use, pass two slanted holes on the frame pla...

The invention discloses a bracket for a simple lifting device with the advantages of convenient use and high safety and reliability. The bracket comprises two bracket levers, a bearing rod, and a bracket disk, wherein two inclined through-holes in a vertical direction are arranged on the bracket disk, two symmetric lugs are arranged on the side face of the bracket disk, bolts are arranged at the centers of the lugs, the two bracket levers respectively pass through the two inclined holes on the bracket disk, shaft holes are arranged at one end of each bracket lever, the ends where the shaft holes are arranged are positioned between the two lugs, and the bolts pass through the shaft holes. The inventive bracket uses the bracket disk made from various high-strength materials such as metal, metal alloy and engineering plastics, so that the bracket can be repeatedly used for a long time, and has further improved safety. When the bracket is used, the bracket levers need not to be bound, resulting in convenient and rapid operation.
Description
technical field [0001] The invention relates to a loading and unloading lifting device, in particular to a bracket of a simple lifting device. Background technique [0002] With the rapid development of the rural economy and the continuous improvement of farmers' awareness of environmental protection and energy conservation, biogas has been rapidly popularized and applied in rural areas, and more and more farmers have built biogas digesters. During the use of biogas, biogas residue and waste biogas slurry need to be continuously pumped out, and biogas residue and biogas slurry are excellent fertilizers. Farmers use them to return to the field to increase land fertility, which not only saves chemical fertilizers, but also meets environmental protection requirements. When farmers transport biogas residue and biogas slurry, they generally use special pumping storage tanks prepared on tricycles. There is a lot of inconvenience when using the pumping storage tank at present, and...
