[0002] The flywheel housing is a cast iron part, usually used to support the transmission and provide a support point for power transmission.

[0003] There are various structures of existing flywheel housing hangers. For example, the flywheel housing disclosed in CN 202122242802.1 uses a three-way adjustable hanger. Although the structure of the hanger is adjustable, the overall force reliability is poor, and it is impossible to achieve reliable lifting of large-sized and heavy flywheel housings.

[0004] For example, the engine flywheel housing hanger disclosed in CN201920583170.5 is mainly used to solve the problem that the hanger is inconvenient for users to disassemble. The device cannot assemble a flywheel housing with a large weight and size by lifting the hanger.

[0005] Another example is the flywheel housing hanger disclosed in CN200820227577.6, which clamps the inner wall of the flywheel housing with a baffle plate at one end and clamps the outer wall of the flywheel housing with a positioning screw to lift the flywheel housing. However, the contact area between the clamping part of the hanger and the flywheel housing is small, which easily causes stress concentration and damages the surface of the flywheel housing, and is difficult to disassemble.

[0035] The spring 5 is sleeved on the movable shaft 9, and the two ends of the spring 5 are respectively connected to the movable shaft 9 and the base 1. The movable shaft 9 here can be provided with a cap body on the top surface, and one end of the spring 5 is connected to the bottom surface of the cap body. When the pendulum block 2 is pressed down, the spring 5 is compressed, and when the pendulum block 2 is tilted up, the spring 5 is pushed up.

[0036] In a specific embodiment, the stopper 6 is fixedly connected to the movable shaft 9 via an elastic cylindrical pin 11 .

[0037] In a specific embodiment, the clamping blocks are symmetrically arranged in pairs on the bottom surface of the stopper 6, and the clamping blocks are vertically extended to the contact block 7 to increase the contact area with the flywheel housing and improve the clamping reliability.

[0045] When in use, it is connected to a lifting device such as a gantry crane or a crane's sling or hook through a D-type shackle 3. When the sling is working, after one end of the pendulum block 2 is subjected to force, the other end presses down on the movable shaft 9, moves downward and extends out of the base 1, and then presses down on the stopper, so that the space between the stopper 6 and the contact block 7 is reduced, clamping the flywheel housing accommodated between the stopper 6 and the contact block 7, and then hoisting or transporting the flywheel housing.

[0046] When the lifting device is not working, one end of the pendulum block 2 is not subjected to force, and the spring 5 props up the movable shaft pendulum block 2 to move upward, so that the space between the stopper 6 and the contact block 7 is expanded, forming an open posture, and the lifting device is separated from the flywheel housing. The lifting device has a reliable force structure, and can use the pendulum block 2 to obtain a more reliable clamping force during lifting.
