DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 4 The utility model provides a technical solution: a cylinder head production line hanger, including a connecting piece 3, a hanger rod 4, a step cylinder 5, a transmission rod 12 and a limit pin 10, the hanger rod 4 is fixed to the lower end of the connecting piece 3, the lower end of the step cylinder 5 is fixed with a hanger shell 7 through a flange and bolts, the hanger rod 4 passes through the step cylinder 5, and the left and right ends of the hanger shell 7 are both installed with bearing seats 11 on the front and rear sides, and two transmission rods 12 are provided. The two transmission rods 12 respectively penetrate the inner rings of multiple bearing seats 11, and the middle of the two transmission rods 12 is installed with a loose grip adjustment rod 15. The upper ends of the front sides of the two loose grip adjustment rods 15 are both provided with an elliptical movable groove 9, and the limit pin 10 passes through the two elliptical movable grooves 9. The front and rear ends of the two loose grip adjustment rods 15 are both fixed with a bent hook 14 through a plurality of reinforcing bolts 13, and the plurality of bent hooks 14 are respectively hung on the two cylinder head hangers 81. This design solves the problem that the original cylinder head hanger may fall off during the lifting process.

[0020] As the first embodiment of the utility model: a reinforcement block 2 is fixed on the upper end of the connecting plate 3, and a lifting ring 1 is installed on the upper end of the reinforcement block 2. The added lifting ring 1 facilitates the connection of the device with external suspension equipment. An anti-slip ring is welded on the upper end of the annular side surface of the sling rod 4, and the anti-slip ring is located at the upper end inside the step tube 5. The added anti-slip ring allows the sling rod 4 to move to a certain extent inside the step tube 5 without falling off. An elliptical groove is provided on the side surface of the sling rod 4 ring, and a limit block 6 is installed through the left end of the outside of the sling shell 7. The limit block 6 passes through the elliptical groove. The added limit block 6 can prevent the sling rod from falling off inside the step tube 5.

[0021] The upper ends of the two loose grip adjustment rods 15 and the limit pin 10 are both movably located inside the sling shell 7, and the lower end of the sling rod 4 is movably attached to the connection between the upper ends of the two loose grip adjustment rods 15. The added limit pin 10 can prevent the two loose grip adjustment rods 15 from swinging excessively in the sling shell 7. Two cylinder head suspension rods 81 are respectively fixed to the left and right sides of the upper end of the cylinder head body 8. A positioning piece 16 is installed at the lower end of the sling shell 7, and the positioning piece 16 is attached to the upper end of the cylinder head body 8. The added cylinder head suspension rod 81 facilitates the multiple bent hooks 14 to lift the cylinder head body 8.

[0022] As a second embodiment of the present utility model: when it is necessary to lift the cylinder head body 8, the lifting ring 1 is connected to the external suspension equipment, and the device is moved above the cylinder head body 8, so that the multiple bent hooks 14 are in contact with the upper ends of the two cylinder head suspension rods 81, and then the hanger rod 4 is pressed down, and the hanger rod 4 will push the two loose grip adjustment rods 15 to swing in a circular direction (in this process, the anti-slip ring moves downward in the step cylinder 5, the elliptical groove moves downward outside the limit block 6, and the limit pin 10 moves in the two elliptical movable grooves 9, which will not affect the swing effect of the two loose grip adjustment rods 15), so that the other ends of the two loose grip adjustment rods 15 will drive the two transmission rods 12 to rotate in place, so that the multiple bent hooks 14 will open and slide from the two cylinders. The upper end of the cover suspension rod 81 slides down until the positioning piece 16 is in contact with the upper end of the cylinder cover body 8, and then the lifting ring 1 is pulled up. The lifting ring 1 will pull up the sling rod 4 through the reinforcement block 2 and the connecting piece 3 (at this time, the anti-slip ring moves upward in the step tube 5, and the elliptical groove moves upward outside the limit block 6), so that the lower end of the sling rod 4 does not contact the two loose grip adjustment rods 15. At this time, because the center of gravity of the multiple bent hooks 14 is on the lower side, their lower ends will swing toward each other and hook the lower sides of the front and rear ends of the two cylinder cover suspension rods 81 (in this process, the multiple bent hooks 14 will drive the two transmission rods 12 to rotate in the opposite direction, and the two transmission rods 12 will drive the two loose grip adjustment rods 15 to reset, and the limit pins 10 will also reset), thereby realizing the suspension of the cylinder cover body 8, refer to Figure 1 .
