[0024] The following diagrams illustrate various embodiments of the present invention. For clarity, many physical details will be included in the following description. However, it should be understood that these physical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these physical details are not essential. Furthermore, to simplify the illustrations, some commonly used structures and components are depicted in a simplified schematic manner.

[0025] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0026] In the description of this technology, it should also be noted that, unless otherwise specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this technology based on the specific circumstances.

[0027] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0028] See also Figure 1-6 The utility model provides a flywheel housing blank outer contour grabbing and lifting device, comprising two fixed plates 1 and two clamping arms 7. The two fixed plates 1 are arranged in parallel, and a connecting block 2 is fixedly connected in the center between the two fixed plates 1. A lifting assembly is provided in the center of the upper surface of the connecting block 2. The two clamping arms 7 are rotatably connected to the two side positions between the two fixed plates 1, and the two clamping arms 7 are symmetrically arranged. Specifically, the front of the clamping arm 7 is an "L"-shaped structure, and an axial hole 9 is provided at the bending part of the clamping arm 7. Through holes are provided at positions near both sides of the fixed plate 1. A connecting shaft 14 is inserted between the axial hole 9 and the through hole, and the clamping arm 7 is rotatably connected to the connecting shaft 14.

[0029] Both sides of the lifting assembly are fixedly connected to the upper surface of the two clamping arms 7 and the side close to the connecting block 2 through chains 13, and a clamping head is installed at the bottom of the clamping arm 7 away from the center of the fixed plate 1.

[0030] The lifting assembly includes a limit rod 3 and a movable sleeve 4. The limit rod 3 is fixedly connected to the center of the upper surface of the connecting block 2. The movable sleeve 4 is sleeved on the surface of the limit rod 3 in the vertical direction. The first connecting ring 5 is fixedly connected to both sides of the movable sleeve 4 near the bottom. The second connecting ring 8 is fixedly connected to the upper surface of the clamping arm 7 and one side close to the connecting block 2. The two ends of the chain 13 are respectively fixedly connected to the first connecting ring 5 and the second connecting ring 8. The center of the top of the movable sleeve 4 is fixedly connected to a lifting ring 6. The inner wall of the movable sleeve 4 fits with the surface of the limit rod 3.

[0031] See also Figure 4By setting up the lifting assembly, after the lifting equipment is connected to the lifting ring 6, when the lifting equipment is controlled to move upward, the movable sleeve 4 will be driven to move upward, and then under the action of the chain 13 pulling, the clamping arm 7 will be rotated upward. The function of the limit rod 3 is to ensure that the movable sleeve 4 can only move in the vertical direction, thereby ensuring that the clamping arms 7 at both ends are evenly stressed.

[0032] Therefore, when the flywheel housing needs to be hoisted, it is only necessary to place the clamping head at the lower end of the clamping arm 7 under the flywheel housing, and then operate the device to drive the movable sleeve 4 to move upward. At this time, the clamping head is tilted to clamp the lower end of the flywheel housing.

[0033] In this embodiment, the clamping head includes a connecting sleeve 10 and a protrusion 11. The connecting sleeve 10 is inserted into the bottom of the short side of the clamping arm 7. Several connecting holes 12 are opened on one side of the connecting sleeve 10. The clamping arm 7 is opened at the position corresponding to the connecting hole 12. A threaded hole is opened. A bolt is arranged between the connecting hole 12 and the threaded hole. The protrusion 11 is arranged on the side of the connecting sleeve 10 away from the connecting hole 12. The protrusion 11 is a cylindrical structure and is integrally formed with the connecting sleeve 10. The two protrusions 11 are both facing the center position of the fixed plate 1.

[0034] By setting a connecting sleeve 10 in the clamping head, cooperating with the connecting hole 12 set on the connecting sleeve 10 and the threaded hole set on the clamping arm 7, the clamping head can be fixed to the clamping arm 7 by bolts, which is convenient for the staff to disassemble and replace the clamping head. The setting of the cylindrical protrusion 11 can reduce the wear between the flywheel housing and the cylindrical protrusion 11. At the same time, the setting of the cylindrical protrusion 11 can also provide a more stable support for the flywheel housing.

[0035] In some other embodiments, pads 15 are fixedly connected at the bottom and near both sides between the two fixing plates 1 .

[0036] The provision of the pad 15 can increase the contact area between the lower surface of the clamping arm 7 and the upper surface of the flywheel housing, thereby improving the stability during the lifting and transfer process.

[0037] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
