[0037] Embodiment 1

[0038] See also Figure 1 and Figure 2 In one embodiment of the present application, a lifting tool 100 is provided. The lifting tool 100 is used for lifting a piston 200 .

[0039] The piston 200 in this embodiment has a combustion chamber 210 , and the lifting tool 100 can cooperate with the inner wall of the combustion chamber 210 to lift the piston 200 .

[0040] The lifting tool 100 mainly includes a first support member 110 , a second support member 120 , a support rod 130 , a first lifting ring 140 and a second lifting ring 150 .

[0041] The first support member 110 has a first abutting surface 111 ; the shape of the first abutting surface 111 matches the shape of the inner wall of the combustion chamber 210 .

[0042] The second supporting member 120 has a second abutting surface 121 ; the shape of the second abutting surface 121 matches the shape of the inner wall of the combustion chamber 210 .

[0043] The support rod 130 has a first end 131 and a second end 132 opposite to each other; the first end 131 is adjustably disposed on the first support member 110 , and the second end 132 is adjustably disposed on the second support member 120 .

[0044] By rotating the support rod 130, the telescopic amount of the first end 131 extending into the first support member 110, or the telescopic amount of the second end 132 extending into the second support member 120 can be adjusted, thereby adjusting the distance between the first support member 110 and the second support member 120, so that the first abutting surface 111 and the second abutting surface 121 can both abut against the opposite inner walls of the combustion chamber 210, thereby fixing the lifting tool 100 in the combustion chamber 210.

[0045] The first lifting ring 140 is fixed to the first support member 110; the second lifting ring 150 is fixed to the second support member 120. The first lifting ring 140 and the second lifting ring 150 are both used to fix the traction rope 300. A lifting device such as a crane outside can lift the lifting tool 100 fixed in the combustion chamber 210 through the traction rope 300, thereby driving the piston 200 to rise or fall.

[0046] When the lifting tool 100 of this embodiment lifts the piston 200 , there is no need to open an additional lifting hole on the piston 200 .

[0047] The first abutting surface 111 is disposed on a side of the first supporting member 110 away from the supporting rod 130 ; the second abutting surface 121 is disposed on a side of the second supporting member 120 away from the supporting rod 130 .

[0048] By rotating the support rod 130 along the first direction, the distance between the first support member 110 and the second support member 120 can be reduced, so that the hoisting tool 100 can be placed in the combustion chamber 210 .

[0049] When the lifting tool 100 is placed in the combustion chamber 210, by rotating the support rod 130 along a second direction opposite to the first direction, the distance between the first support member 110 and the second support member 120 can be increased, so that the first abutting surface 111 and the second abutting surface 121 can both abut against the inner wall of the combustion chamber 210, thereby enabling the lifting tool 100 and the piston 200 to move synchronously.

[0050] When the piston 200 is hoisted, the support rod 130 is rotated along the first direction to reduce the distance between the first support member 110 and the second support member 120, so that the first abutment surface 111 or the second abutment surface 121 is separated from the inner wall of the combustion chamber 210, thereby allowing the hoisting tool 100 to be taken out of the combustion chamber 210.

[0051] When the first direction is counterclockwise, the second direction is clockwise. When the first direction is clockwise, the second direction is counterclockwise.

[0052] In some embodiments, a first connecting hole is formed on a side of the first supporting member 110 away from the first supporting surface 111, and a second connecting hole is formed on a side of the second supporting member 120 away from the second supporting surface 121; a first internal thread is formed on an inner wall of the first connecting hole, and a first external thread corresponding to the first internal thread is formed on an outer surface of the first end 131; a second internal thread is formed on an inner wall of the second connecting hole, and a second external thread corresponding to the second internal thread is formed on an outer surface of the second end 132.

[0053] The first end 131 cooperates with the inner wall thread of the first connecting hole, and the second end 132 cooperates with the inner wall thread of the second connecting hole; and the rotation directions of the first internal thread and the second internal thread are opposite, and the rotation directions of the first external thread and the second external thread are opposite, so that when the support rod 130 is rotated, the distance between the first support member 110 and the second support member 120 can be increased or reduced.

[0054] Preferably, the first support member 110 and the second support member 120 are symmetrically arranged with the support rod 130 as the center, so that when the support rod 130 is rotated, the amount of extension of the first end 131 into the first connecting hole is always equal to the amount of extension of the second end 132 into the second connecting hole.

[0055] In some embodiments, see Figure 2 The support rod 130 is provided with a rotating portion 133. The operator can drive the support rod 130 to rotate by rotating the rotating portion 133.

[0056] Preferably, the rotating portion 133 is disposed at the center of the supporting rod 130 .

[0057] In some embodiments, the rotating portion 133 is disposed along the circumference of the support rod 130 and protrudes from the outer surface of the support rod 130 along the radial direction of the support rod 130 .

[0058] In some embodiments, the cross-sectional shape of the rotating portion 133 along the radial direction of the support rod 130 is hexagonal, so that the operator can rotate the support rod 130 by using a tool such as a wrench. It can be understood, but not limited to this, in other embodiments, the cross-sectional shape of the rotating portion 133 along the radial direction of the support rod 130 can also be other shapes such as a pentagon.

[0059] In some embodiments, see Figure 1 A first connecting rod is provided on the first hanging ring 140 , and one end of the first connecting rod away from the first hanging ring 140 is inserted into and fixed in the first supporting member 110 , so that the first hanging ring 140 is fixed on the first supporting member 110 .

[0060] A second connecting rod is disposed on the second hanging ring 150 , and one end of the second connecting rod away from the second hanging ring 150 is inserted into and fixed in the second supporting member 120 , so that the second hanging ring 150 is fixed on the second supporting member 120 .

[0061] In some embodiments, the hoisting tool 100 further includes a first fixing seat 160 and a second fixing seat 170; the first fixing seat 160 is fixed to the first support member 110, and the second fixing seat 170 is fixed to the second support member 120; one end of the first connecting rod away from the first lifting ring 140 is passed through the first fixing seat 160 and fixedly connected to the first support member 110, so that the first lifting ring 140 is fixedly connected to the first fixing seat 160. One end of the second connecting rod away from the second lifting ring 150 is passed through the second fixing seat 170 and fixedly connected to the second support member 120, so that the second lifting ring 150 is fixedly connected to the second fixing seat 170.

[0062] By providing the first fixing seat 160 on the first supporting member 110, the length of the first connecting rod can be increased to improve the reliability of the connection between the first lifting ring 140 and the first supporting member 110. By providing the second fixing seat 170 on the second supporting member 120, the length of the second connecting rod can be increased to improve the reliability of the connection between the second lifting ring 150 and the second supporting member 120.

[0063] Exemplarily, the first fixing seat 160 and the first supporting member 110 are integrally formed; the second fixing seat 170 and the second supporting member 120 are integrally formed.

[0064] Exemplarily, the first fixing seat 160 is disposed above the first supporting member 110 ; and the second fixing seat 170 is disposed above the second supporting member 120 .

[0065] In some embodiments, the first support member 110 and the second support member 120 are both elastic support blocks to prevent the first support member 110 and the second support member 120 from scratching the inner wall of the combustion chamber 210 .
