[0010] Figure 1 This is a schematic diagram of the overall structure of the utility model;

[0011] Figure 2 It is a perspective view of the overall structure of the utility model. DETAILED DESCRIPTION

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0013] The cam 2 is provided with a plurality of adjusting screw holes, and the adjusting screw holes are provided on the lower surface of the cam 2. The adjusting screw holes are provided on the lower surface of the cam 2 and the lower surface of the cam 2 are provided.

[0014] There are two rollers 3 , which are arranged opposite to each other, and the outer circles of the rollers 3 are supported on the front and rear end journals of the crankshaft.

[0015] A hydraulic lifting rod 6 is provided below the lifting platform 5 .

[0016] A motor 7 is provided on one side of the lifting platform 5, a driving wheel 8 is provided at the output end of the motor, and a secondary wheel 9 is provided on the roller close to the motor side. The secondary wheel 9 and the roller 3 are coaxial and fixed as a whole, and the secondary wheel 9 and the driving wheel 8 are connected by a belt.

[0017] In order to facilitate the adjustment of the overall device of the present application with the hexagonal bolts on the unloading platform, the width of the outer frame of the support frame is greater than the width of the lifting platform, so that there is working space above the hexagonal bolts.

[0018] The working principle of the present utility model is as follows: the two ends of the crankshaft are respectively placed on the rollers of the device, and then the adjustment link can be carried out. The lifting platform provides the power for lifting and lowering the crankshaft through the hydraulic lifting rod. Due to the structural characteristics of the outer frame of the support frame, the movement direction of the support frame and the lifting platform can be constrained during the rising and lowering process. At the same time, the support frame is placed inside the lifting platform, and the two sides of the lifting platform are gap-matched with the outer frame of the support frame. The lifting platform can be raised and lowered inside the support frame, and the two side surfaces of the support frame play a guiding role. When the crankshaft needs to be rotated, the motor can be turned on to rotate the driving wheel, and the secondary wheel is driven to rotate by the belt at the same time. Since the secondary wheel and the roller are fixed as one, the rotation of the roller is realized. Since the roller supports the front and rear end journals of the crankshaft, the crankshaft also rotates accordingly. Since it is only fine-tuning, the crankshaft does not need to rotate quickly, so the friction between the end of the crankshaft and the outer circle of the roller is sufficient for the rotation of the crankshaft.
