[0031] Embodiment 2

[0032] See also Figure 1-6 A hoisting tool for a marine methanol diesel engine injector comprises a hoisting assembly, a methanol injector 5, and a cylinder head 6. The cylinder head 6 is provided with a mounting hole. The bottom of the methanol injector 5 can be fitted with the mounting hole of the cylinder head 6. The top of the methanol injector 5 is provided with a matching hole and a combined threaded hole. The hoisting assembly comprises a bracket 1, a hoisting plate 2, and a fixed moment tube 4. The bottom of the hoisting plate 2 and the bottom of the fixed moment tube 4 are respectively connected to the surfaces of both sides of the top of the bracket 1. A plurality of threaded holes are opened inside one side of the bracket 1, and bolts 3 are threadedly connected in the plurality of threaded holes.

[0033] The bottom of the hanging plate 2 and the top of the bracket 1, and the bottom of the fixed moment tube 4 and the top of the bracket 1 are fixed by welding, which fully ensures the connection strength between the fixed moment tube 4 and the bracket 1 and the connection strength between the hanging plate 2 and the bracket 1;

One end of the bolt 3 can be threadedly connected in the corresponding threaded hole and the corresponding combination threaded hole, respectively. By using the cooperation between the bolt 3 and the threaded hole, the bracket 1 and the methanol injector 5 can be stably installed together;

[0035] Two fixed moment tubes 4 are provided, and the two fixed moment tubes 4 are symmetrically mounted on the top of the bracket 1, thereby ensuring that the bolts can be effectively matched with the methanol injector when the bracket 1 is tilted. The bracket 1 is a T-shaped structure as a whole, and a clearance hole and four auxiliary holes are opened in the middle of the bracket 1, and two of the auxiliary holes are respectively aligned with the two fixed moment tubes 4;

[0036] Two lifting holes are provided inside the lifting plate 2, and after the lifting assembly and the methanol fuel injector 5 are in the lifting state, one of the lifting holes inside the lifting plate 2 and the center of gravity of the methanol fuel injector 5 are on the same straight line, and the angle formed by the other lifting hole inside the lifting plate 2 and the center of gravity of the methanol fuel injector 5 is consistent with the angle of the mounting hole of the cylinder head 6;

[0037] Magnets are embedded on the inner sides of one ends of the four bolts 3, so that when the bolts 3 are not in use, they can be prevented from being detached from the corresponding threaded holes in the bracket 1 by threaded connection and magnetic connection, thereby preventing the bolts 3 from being lost during long-term reciprocating use. The corners at the top of the hanging plate 2 are set to a rounded structure to prevent the structure from scratching the user, and the angle between another hanging hole inside the hanging plate 2 and the center of gravity of the methanol injector 5 has a numerical range of 0-45° to meet different usage requirements.

[0038] Working principle: When in use, the bracket 1 is installed on the methanol injector 5. The matching hole set on the top of the methanol injector 5 provides installation clearance, and there is a small gap between the bottom structure of the bracket 1 and the matching hole. The corresponding positions of the bracket 1 and the top of the methanol injector 5 are inclined. Then, the bolts 3 are unscrewed from the four threaded holes inside the bracket 1 and are respectively threaded into the four combined threaded holes set on the top of the methanol injector 5, so as to perform a detachable and stable installation of the bracket 1 and the methanol injector 5. Then, the lifting assembly as a whole and the methanol injector 5 are lifted together through the lifting plate 2 through the existing lifting equipment.

Thus, during long-term reciprocating use, the bolts 3 can be avoided from being lost, further optimizing the use effect.
