DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 3A diesel engine crane device includes a frame 1, a plurality of rollers 13 are fixed to the bottom of the frame 1 by bolts, a fixing seat 2 is fixed to the top of the frame 1 by bolts, a support frame 3 is rotatably connected to the top of the fixing seat 2, a toggle handle 16 is welded to one side of the support frame 3, the toggle handle 16 is pulled to drive the support frame 3 to rotate, thereby driving the lifting arm 4 to rotate, and then adjusting the lifting direction, the top of the support frame 3 is rotatably connected to the lifting arm 4 through a rotating shaft, and the inner walls on both sides of the lifting arm 4 are provided with slide grooves 6, an electric push rod 5 is fixed to the bottom of the support frame 3 by bolts, a slider is fixed to the top of the electric push rod 5 by bolts, and the slider slides in the slide groove 6 The slider moves in the slide groove 6 driven by the electric push rod 5, thereby driving the lifting arm 4 to rotate upward, and then lifting the diesel engine. One end of the lifting arm 4 is provided with a through hole 7, and two lifting ropes 9 are inserted in the through hole 7. The other two ends of the lifting rope 9 are fixed with hooks 10. The bottom inner wall of the through hole 7 is integrally formed with a partition protrusion 8. The two lifting ropes 9 are respectively located on both sides of the partition protrusion 8. The two lifting ropes 9 are separated by the partition protrusion 8 to avoid the entanglement of the two lifting ropes 9, so that the force is evenly distributed when the diesel engine is lifted, thereby preventing the diesel engine from shaking. The top of the partition protrusion 8 is rotatably connected to two clamping plates 11, and the lifting rope 9 is fixed by the clamping plates 11.
