[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] The following describes the combustion engine transition section disassembly and assembly device according to the embodiment of the utility model with reference to the accompanying drawings. Figures 1 to 3 As shown, the combustion engine transition section disassembly and assembly device according to an embodiment of the present utility model includes a first frame 1, a second frame 2, a first moving part and a gripper 3.

[0035] The first frame 1 has a first predetermined dimension in a first direction. The second frame 2 is movably mounted on the first frame 1 along the first direction. A first movable portion is mounted on the first frame 1 and can drive the second frame 2 to move in the first direction. A gripper 3 is used to grasp the transition section. The gripper 3 is connected to the second frame 2 and can rotate relative to the second frame 2, with the rotation axis of the gripper 3 extending in the first direction.

[0036] According to an embodiment of the present invention, the gripper 3 of the gas turbine transition section assembly and disassembly device can grasp the transition section, and the first frame 1 can be connected to the gas turbine. The first movable portion can drive the second frame 2 to move in a first direction, thereby enabling the gripper 3 to move in the first direction and also driving the transition section on the gripper 3 to move in the first direction. The gripper 3 can also rotate relative to the second frame 2 to rotate the transition section so that it can be aligned with the gas turbine installation position, thereby facilitating the assembly and disassembly of the gas turbine transition section.

[0037] Therefore, the combustion engine transition section disassembly and assembly device according to the embodiment of the utility model has the advantage of facilitating the disassembly and assembly of the combustion engine transition section.

[0038] like Figure 1 and Figure 2 As shown, in some embodiments, the second frame 2 is provided with a second movable portion, which is connected to the gripper 3. The second movable portion can drive the gripper 3 to move in the first direction, and the gripper 3 can rotate relative to at least a portion of the second movable portion. In other words, the second frame 2 is provided with a second movable portion that can drive the gripper 3 to move in the first direction, allowing the gripper 3 to perform a second movement, thereby further increasing the range of movement of the gripper 3 in the first direction, thereby facilitating the disassembly of the transition section of the combustion engine.

[0039] In some embodiments, the diameter of the second screw 5 is greater than or equal to 0.1 meter and less than or equal to 0.4 meter. The larger diameter of the second screw 5 can facilitate supporting the gripper 3. For example, the diameter of the second screw 5 is 0.2 meter.

[0040] like Figure 1 and Figure 2As shown, in some embodiments, the second movable portion includes a second screw 5 and a second handle 51. The length of the second screw 5 is oriented in the first direction. Rotating the second handle 51 can cause the second screw 5 to move relative to the second frame 2 in the first direction. Specifically, the axis of the second screw 5 coincides with the center of the second frame 2. A staff member rotates the second handle 51, thereby causing the second screw 5 to rotate and move in the first direction.

[0041] like Figure 1 and Figure 2 As shown, in some embodiments, the second moving portion includes a second screw 5 , a second limiting portion 52 , a second nut and a second handle 51 .

[0042] The second nut is rotatably provided on the second frame 2, and the second nut is sleeved on the outer circumference of the second lead screw 5. The internal thread on the inner side of the second nut is threadedly connected to the external thread on the outer circumference of the second lead screw 5. The second limiting portion 52 cooperates with the second lead screw 5 to limit the second lead screw 5 to move in the first direction, and the second handle 51 is connected to the second nut to drive the second nut to rotate. Specifically, the second nut is threadedly connected to the second lead screw 5, and the second limiting portion 52 can limit the second lead screw 5 so that the second lead screw 5 can only move in the first direction. When the second handle 51 drives the second nut to rotate, the second nut is threadedly connected to the second lead screw 5, thereby driving the second lead screw 5 to move in the first direction.

[0043] In some embodiments, the outer surface of the second lead screw 5 has a limiting groove, and the limiting groove extends along the first direction. The second limiting portion 52 is provided on the second frame 2, and the second limiting portion 52 includes a limiting block extending into the limiting groove. The shape and size of the limiting block are adapted to the shape and size of the limiting groove, and the limiting block is slidably connected to the limiting groove in the first direction. Specifically, the limiting groove is a groove body concave on the outer surface of the second lead screw 5, and the limiting block is located on the inner side of the second limiting portion 52. The second limiting portion 52 is fixed on the second frame 2, so that the limiting block can be fixed relative to the second frame 2. The limiting block extends into the limiting groove to limit the second lead screw 5 and prevent the second lead screw 5 from rotating, so that the second lead screw 5 can move in the first direction when the second nut rotates. For example, the outer peripheral contour of the projection of the limiting groove and the limiting block in the cross section perpendicular to the first direction is a rectangle.

[0044] In some embodiments, the outer peripheral contour of the projection of the cross section of the limiting groove and the limiting block in a direction perpendicular to the first direction is a trapezoid, and the longer bottom side (lower bottom) of the cross section of the limiting groove and the limiting block is adjacent to the axis position of the second lead screw 5 .

[0045] In some embodiments, the second screw 5 is threadedly connected to the second frame 2, and the second handle 51 is connected to the second screw 5 to drive the second screw 5 to rotate. Specifically, the second screw 5 is directly threadedly connected to the second frame 2, and the second screw 5 can move relative to the second frame 2 in the first direction when rotating.

[0046] In some embodiments, the first frame 1 includes a connecting support 11 , a fixing support 12 and a plurality of first connecting rods 13 .

[0047] The first connecting rod 13 extends in the first direction, and the connecting support 11 and the fixed support 12 are both annular. The connecting support 11 and the fixed support 12 are connected by multiple first connecting rods 13, and the multiple first connecting rods 13 are arranged at intervals along the circumference. The connecting support 11 is used to connect to the fuel engine. Specifically, the connecting support 11 and the fixed support 12 are both circular rings. The connecting support 11 has multiple connecting holes 14 arranged at intervals along the circumference, and the connecting holes 14 pass through the connecting support 11 in the first direction. The connecting support 11 is connected to the flange on the fuel engine through the multiple connecting holes 14 and multiple bolts, so that the first frame 1 can be detachably connected to the fuel engine. For example, the first connecting rod 13 is a round rod extending in the first direction.

[0048] In some embodiments, the length of the first frame 1 is greater than or equal to 1 meter and less than or equal to 2 meters. For example, the length of the first frame 1 is equal to 1.5 meters.

[0049] like Figure 1 and Figure 2 As shown, in some embodiments, the second frame 2 is slidably connected to the plurality of first connecting rods 13 via a plurality of connecting plates 21. Specifically, the second frame 2 includes a frame body and a plurality of connecting plates 21, and the connecting plates 21 are slidably connected to corresponding first connecting rods 13, thereby allowing the second frame 2 to slide relative to the first frame 1 in a first direction.

[0050] In some embodiments, the first movable portion includes a first screw 4 and a first nut. The first screw 4 extends along a first direction. The first screw 4 is rotatably mounted on the connecting support 11 and the fixed support 12. The first screw 4 is provided with a first handle 41, which can drive the first screw 4 to rotate. The first handle 41 and the second handle 51 are both located on the side of the fixed support 12 facing away from the connecting support 11. The first screw 4 is threadedly connected to the first nut, which is connected to the second frame 2. Specifically, the first nut is fixed to a connecting plate 21 of the second frame 2. The first handle 41 can drive the first screw 4 to rotate, thereby driving the first nut to move in the first direction, thereby driving the second frame 2 to move in the first direction.

[0051] At least part of the second screw 5 is located inside the first frame 1. The axis of the second screw 5 is located at the same position as the axis of the connecting support 11. The first movable portion and the second movable portion cooperate to drive the gripper 3 to move to the side of the connecting support 11 facing away from the fixed support 12. This facilitates the movement of the transition section to the outside of the first frame 1 and installation in the combustion engine.

[0052] The gripper 3 is sleeved on the outer circumference of the second lead screw 5, and the inner internal thread of the gripper 3 is threadedly connected to the outer external thread of the outer circumference of the second lead screw 5. Specifically, the gripper 3 includes a gripping disc 31 and a plurality of claws 32. The gripping disc 31 is connected to the second frame 2 (via the second movable portion), and the gripping disc 31 is threadedly connected to the second lead screw 5. The gripping disc 31 can rotate relative to the second frame 2, and the extension direction of the rotation axis of the gripping disc 31 is the first direction. Each claw 32 has a slot with an opening facing inward, and at least one of the plurality of claws 32 is detachably connected to the gripping disc 31. Thus, after one claw 32 is removed, the transition section can be clamped into the slots of the remaining plurality of claws 32, and then the last claw 32 can be installed on the gripping disc 31 to fix the transition section. For example, three claws 32 are provided on the circumference of the gripping disc 31, and the shaft of the claw 33 is detachably connected to the gripping disc 31 by bolts.

[0053] In some embodiments, at least one claw 32 is adjustable in the radial direction of the gripping disc 31. For example, the gripping disc 31 is provided with a movable groove extending along its radial direction, and the shaft of the claw 32 is fitted into the movable groove.
