Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to a novel eccentric gravity center hanging tool for a rotary shell. Background Art

[0002] The new eccentrically-gravated lifting tool for rotating housings is primarily used in industrial production, construction, and logistics. During mechanical manufacturing, various rotating housing parts often require handling and installation. This lifting tool can accurately lift rotating housings of varying sizes and weights, such as engine blocks and gearbox housings, facilitating processing, assembly, and transportation.

[0003] Some existing lifting tools cannot adjust to the workpiece's angle. When lifting rotating shell workpieces at different angles, this inability to adjust the angle requires additional tools or complex operations, significantly increasing work time. For example, it can take multiple attempts to find the right angle, resulting in low work efficiency. To address this issue, a new eccentric-center-of-gravity lifting tool for rotating shells has been proposed. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 3 、 Figure 4 The present invention provides an embodiment of a novel eccentric center-of-gravity hanging tool for a rotary shell, comprising an eccentric hanging plate 1. The eccentric hanging plate 1 is made of high-strength alloy steel, exhibiting extremely high strength and toughness, capable of withstanding large lifting weights and ensuring no deformation or damage during the lifting process. A sliding groove 5 is defined within the eccentric hanging plate 1.

[0024] The sliding groove 5 is precision-machined to high dimensional accuracy and a smooth surface, allowing the locking nut 2 to rotate and slide smoothly within it, preventing any jamming when rotating the slider 3. The locking nut 2 is rotatably connected to the interior of the sliding groove 5. Made of high-quality stainless steel, the locking nut 2 offers excellent corrosion resistance and strength, ensuring stable performance even in frequent use and reliably securing the slider 3.

[0025] Reference Figure 1 、 Figure 2 , the rear end of the locking nut 2 is rotatably connected to the slider 3. The slider 3 is made of high-strength aluminum alloy, and the surface is specially treated to have good wear resistance and anti-slip properties. It can fit tightly on the eccentric hanger plate 1 and be firmly connected to the mold 7. Arc grooves are provided on both sides of one end of the eccentric hanger 1. The shape and size of the arc grooves have been carefully designed to perfectly fit molds 7 of different shapes and sizes, ensuring that the mold 7 will not shake or fall off during the lifting process. A mounting hole 4 is provided inside one side of the eccentric hanger plate 1.

[0026] The position and size of the mounting hole 4 have been precisely calculated to facilitate connection with the lifting equipment, ensuring the safety and reliability of the lifting process. A protrusion is provided on the outside of one of the arc grooves. The protrusion is made of a high-hardness material, which can enhance the ability of the arc groove to engage with the mold 7 and further improve the stability of the lifting. The inside of the arc groove is engaged with the mold 7. The mold 7 is tightly engaged with the arc groove, which can effectively prevent the mold 7 from accidentally falling off during the lifting process, ensuring the safety of the lifting operation. The outer side of the locking nut 2 is rotatably connected to the inside of the sliding groove 5.

[0027] The connecting mode makes the locking nut 2 be able to adjust position flexibly, and facilitates the tightening and loosening operation of the sliding block 3. The inner side of the sliding block 3 is coupled with the outer side of the mold 7. The coupling is tight and reliable, and can transmit enough pulling force in the hoisting process, so as to ensure the safe hoisting of the mold 7. The end of the eccentric lifting plate 1 is provided with a driving assembly for driving the parts. The driving assembly comprises a rotating handle 6. The rotating handle 6 is ergonomically designed, comfortable to hold, and convenient for the operator to rotate, so as to drive the locking nut 2 to adjust.

[0028] Working principle: when the staff needs to hoist the mold 7, one end of the eccentric lifting plate 1 can be installed on the hoisting machine, because one end of the eccentric lifting plate 1 is provided with an installation hole 4 for conveniently installing the eccentric lifting plate 1. When the installation hole 4 is installed on the hoisting machine, the sliding block 3 can be attached to one side of the eccentric lifting plate 1. The two sides of one end of the eccentric lifting plate 1 are provided with arc grooves, and one side of the arc groove is provided with a protrusion. Therefore, when the eccentric lifting plate 1 hoists the mold 7, the center of gravity of the mold 7 will deviate to the side of the arc groove with the protrusion due to the setting of the eccentric lifting plate 1 itself. The weight of the eccentric lifting plate 1 will cause the overall angle of the eccentric lifting plate 1 to adjust, so that the workpiece can be hoisted according to the required angle of the center of gravity.

[0029] When the mold 7 is hoisted, the staff will attach the sliding block 3 to one side of the eccentric lifting plate 1, pass the locking nut 2 through the inside of the sliding groove 5, and manually rotate the rotating handle 6 to fix the sliding block 3 on one side of the eccentric lifting plate 1. At this time, the sliding block 3 and the eccentric lifting plate 1 will clamp the mold 7 between them, so as to realize stable and firm hoisting of the workpiece without the risk of falling off.

[0030] Finally, it should be pointed out that: the above-mentioned is only the preferred embodiment of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
