[0029] Reference Figure 1 , Figure 2 and Figure 3 The top ends of the two left fixed plates 3 are fixedly connected with U-shaped blocks 23, and the inner wall of the left U-shaped block 23 is rotatably connected with a blocking column 24; the left ends of the top ends of the two front fixed plates 3 are fixedly connected with a support frame 25, and the bottom of the support frame 25 is fixedly connected with a scanning probe 26; the right end of the top end of the rear fixed plate 3 is fixedly connected with a limiting column 27, and the top end of the limiting column 27 is rotatably connected with a monitoring camera 28; the top end of the rotating plate 19 is provided with a groove 29;

[0030] Specifically, by rotating the blocking column 24 to engage with the right U-shaped block 23, the bracket 6 on the left conveyor belt 5 can be prevented from continuing to move. The scanning probe 26 can identify the size of the crankshaft passing through, which is convenient for subsequent arrangements. The monitoring camera 28 can be used to understand the situation above the conveyor belt 5 in real time. The first electric telescopic rod 13 can be fixed through the groove 29 to push the push plate 14 to push the bracket 6 to the right to move.

[0031] Reference Figure 2 , Figure 3 and Figure 4 The front side of the front fixing plate 3 is fixedly connected with a controller 30, and the controller 30 is electrically connected to the DC motor 8, the first electric telescopic rod 13 and the second electric telescopic rod 15 respectively; the outer side of the controller 30 is fixedly connected with a housing 31, and the outer side of the housing 31 is rotatably connected with a dust cover 32;

[0032] Specifically, the controller 30 can control the starting and operating power between the DC motor 8, the first electric telescopic rod 13 and the second electric telescopic rod 15 respectively. The outer shell 31 can prevent the controller 30 from being damaged due to bumps. The dust cover 32 can prevent dust from entering the controller 30 and damaging the electronic components inside.

[0033] Working principle: Before using the device, first, when the DC motor 8 is started, it will drive the left cylinder 4 to start rotating, which not only makes the outer conveyor belt 5 start to operate, but also drives the first bevel gear 9 on the right to rotate through the gear transmission system. Due to the meshing connection of the gears, the second bevel gear 10 will also rotate accordingly, thereby driving the front conveyor belt 5 to start working. At this time, the left conveyor belt 5 smoothly transports the bracket 6 to the front side. When the bracket 6 is transported to the top of the rotating plate 19, the second electric telescopic rod 15 starts to start. This action makes the disc 16 and the cylinder 17 and the rotating plate 19 above it move to the top together. In this process, since the ball 21 slides in the chute 18 outside the cylinder 17, the cylinder 17 and the rotating plate 19 will rotate 90 degrees clockwise. This precise rotation realizes the turning of the bracket 6, making it change from horizontal to vertical. Then the second electric telescopic rod 15 is started to retract, and the cylinder 17 and the rotating plate 19 above it move to the bottom together. Next, the first electric telescopic rod 13 To start working, push the push plate 14 to move to the right, and push the bracket 6 steadily to the front conveyor belt 5, thereby completing the entire transfer process, and through the rotation of the right cylinder 4, the toothed discs 201 on both sides begin to rotate, and the rotation of the toothed discs 201 drives the rotation of the outer chain 202. The chain 202, as a common transmission mechanism, transmits power from one shaft to another shaft through a series of chain links and sprockets, and transmits the rotational power of the toothed disc 201 to the arc block 203. The design of the arc block 203 is unique and ingenious, and can be engaged with the fixed column 7 above the bracket 6. This engagement mechanism ensures that the arc block 203 can drive the bracket 6 to move when it rotates. In addition, by rotating this movable plate 207, it can be lifted to a specific angle to ensure that when the crankshaft needs to be transferred to a high place, it can be achieved. In order to keep the movable plate 207 in a stable position after being lifted, the movable plate 207 can be fixed at the lifted angle by the fixed rod 206 to prevent it from moving or shaking unnecessary during work.
