As shown in Figures 1-3, the engine hanger of the present utility model includes a grabbing device, a connecting plate and a lifting piece, and the grabbing device is fixed on the connecting plate; The plate is arranged above the grabbing device. Specifically, when the engine spreader enters the engine block, it is connected to the engine cylinder hole through the grabbing device, and the lifting part provides a force application part for the transport spreader. In this embodiment, the preferred hoisting part is the hoisting ring 5, and the hoisting machine and the hoisting ring 5 are connected together, and the hoisting tool is hoisted after the hoisting machine generates hoisting force.

Further, the grabbing device includes a left boom 2 and a right boom 1, the left boom 2 and the right boom 1 are cross-shaped and hinged to each other, the tops of the left boom 2 and the right boom 1 are The connecting plate is connected to the suspension ring 5, and the ends of the left boom 2 and the right boom 1 are bent outwards to form a hook 3. Specifically, extend the hanger into the bottom of the cylinder hole, and use the hook 3 on the boom to hook The crankshaft chamber at the bottom of the cylinder hole does not process the blank surface, and then the lifting ring 5 can be used to lift the sling. Further, the hook 3 is also provided with a detachable copper spacer, because the copper spacer is softer than the cast iron cylinder blank, it will not cause the surface of the cylinder to be worn when it is lifted, and the hook 3 The copper pads on the top can be disassembled and replaced after wear and tear, which is convenient for maintenance.

Further, the left boom 2 and the right boom 1 are respectively provided with two groups, and each group of the left boom 2 and the right boom 1 are correspondingly cross-connected, and the connecting plates include a first connecting plate 8 and a second connecting plate 8. plate 9, the tops of the two groups of left booms 2 are fixedly connected through the first connecting plate 8, and the tops of the two groups of right booms 1 are fixedly connected through the second connecting plate 9, forming four hooks 3. Specifically, the two sets of left boom 2 and right boom 1 are overlapped by external force, and the boom is extended into the bottom of the cylinder hole. After losing the external force, under the action of gravity, the left boom 2 and the right boom 1 Rotate and open, and when the four hooks 3 on the boom hook the crank chamber at the bottom of the cylinder bore without processing the blank surface, the four hooks 3 are balanced in force, and the lifting cylinder is more stable and safe.

Furthermore, the left boom 2 includes a first short rod part 22 and a first long rod part 21 fixedly connected with the first short rod part 22 and forming a first angle, and the right boom 1 includes The second short rod part 12 and the second long rod part 11, the second short rod part 12 and the second long rod part 11 are fixedly connected and form a second included angle, the first included angle and the second included angle The angles are equal in size, the first short rod part 22 intersects the second short rod part 12, the first long rod part 21 and the second long rod part 11 intersect and are rotationally connected at the intersection, the first long rod part The rod part 21 and the second long rod part 11 intersect and are rotatably connected at the intersection to form a crossing angle α. In this embodiment, it is preferable to rotate through the pivot pin 4 at the intersection of the first long rod part 21 and the second long rod part 11 Specifically, the first long rod part 21 and the second long rod part 11 are overlapped by an external force. When the crossing angle α is 0°, the boom is extended into the bottom of the cylinder bore. When the external force is lost, under the action of gravity , the first long rod part 21 and the second long rod part 11 will rotate and open around the pivot pin 4. When the crossing angle α is 25°, use the four hooks 3 of the hanger to hook the crankshaft chamber at the bottom of the cylinder bore without processing the blank noodle.
