Mother, 8, cylinder jacket.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
With reference to Fig. 1 and Fig. 2, a kind of marine main engine cylinder jacket lifting device is present embodiments provided, including fixed edge pawl 1,
Active edges pawl 2 and mobile bar 3, fixed edge pawl 1 are fixed on one end of mobile bar 3, and active edges pawl 2 is sheathed on mobile bar 3, fixed edge
Pawl 1 and active edges pawl 2 include extension 4 and hook portion 5, the hook portion 5 of fixed edge pawl 1 and 5 phase of hook portion of active edges pawl 2
To setting, 3 surface of mobile bar offers external screw thread, and active edges pawl 2 is equipped with the first nut 6 backwards to the side of fixed edge pawl 1, and first
Nut 6 is threadedly coupled with mobile bar 3, limits the first nut 6 to the position of active edges pawl 2.The configuration of the present invention is simple, energy
It effectively realizes the crawl to cylinder jacket 8, the outer edge of cylinder jacket 8 is blocked by the hook portion 5 of fixed edge pawl 1 and active edges pawl 2,
Then the side that the first nut 6 is screwed to active edges pawl 2 is adjacent to, prevents active edges pawl 2 to moving on the outside of mobile bar 3, operation letter
Folk prescription just, improves the efficiency of the lifting of cylinder jacket 8.
The present embodiment further includes the second nut 7, and the second nut 7 is sheathed on mobile bar 3 and is set to fixed edge pawl 1 and activity
Between side pawl 2, active edges pawl 2 is limited to 3 medial movement of mobile bar by the second nut 7, active edges pawl 2 is further improved and exists
Grab stability when cylinder jacket 8, the reliability and safety that raising tool uses.
Specifically, fixed edge pawl 1 and active edges pawl 2 are L shaped plate, L shaped plate with a thickness of 18~20mm, make stationary jaw
With movable jaw anti-deformation with higher, the reliability of crawl cylinder jacket 8 is further increased.
Further, the length of hook portion 5 is 60~80mm in the present embodiment, cooperates with the outer edge of cylinder jacket 8, makes hook
Shape portion 5 stablizes crawl cylinder jacket 8, and stability is higher.
Angle formed by the hook portion 5 of the present embodiment and extension 4 is 60~90 °, makes the outer of hook portion 5 and cylinder jacket 8
When EDGE CONTACT, the resultant force that cylinder jacket 8 is applied to the frictional force between the power and cylinder jacket 8 and hook portion 5 of hook portion 5 is downward
Or it is directed toward the direction of extension 4, it prevents hook portion 5 from grabbing 8 exhaust hood of cylinder jacket set 8 and is slid along 5 direction of hook portion, further mentioned
The safety and stability that high tool uses.
Wherein, the diameter ratio of the wide and mobile bar 3 of extension 4 is 1.5~2:1, improves extension 4 and connect with mobile bar 3
Reliability, on the one hand, increase the area that mobile bar 3 is connect with fixed edge pawl 1, on the other hand, active edges pawl 2 is made to be sheathed on movement
When bar 3, active edges pawl 2 keeps qualified tensile property, and active edges pawl 2 is prevented to be arranged the position fracture of mobile bar 3.
To sum up, the present invention realizes the reliable crawl of cylinder jacket 8, improves the efficiency and safety of the lifting of cylinder jacket 8, operation
It is more convenient.
