[0031] like Figure 2 and Figure 3As shown, the adsorption module 11 includes a protective shell 111, a suction cup 112, a paddle 113, a connecting rod 114 and a driven gear 115. There are two connecting rods 114 and two paddles 113. Each connecting rod 114 passes through the paddle 113 and is rotatably connected to the paddle 113. Both ends of the connecting rod 114 are fixedly connected to the inner wall of the protective shell 111.

The emitted laser is refracted by refractive mirror 1 242 and refractive mirror 243 to form a detection surface. The reflected laser is refracted by refractive mirror 1 242 and refractive mirror 3 244 and then returns to the laser receiving module 245.

[0038] The following is the operating principle of the present utility model.

[0039] Before the crane starts working, install the laser radar device 2 on the platform of the crane; at the same time, turn the paddle 113 of the acceleration acquisition device 1 to make the suction cup 112 at the bottom leak out, and stick the suction cup 112 on the left and right sides of the hoisted component, and turn on its battery switch 133; finally, turn on the display device to check whether the signal transmission is smooth.

[0040] After the crane starts working, the acceleration acquisition device 1 begins to autonomously collect object acceleration in real time as the hook moves. The accelerometer 134 collects the acceleration of the crane hoisted component in real time and transmits the collected acceleration data to the signal receiving module in the crane cab in real time through the signal conversion module 136 and the signal transceiver module 135. After being transmitted through the signal processor 25, the speed of the crane hoisted component is displayed on the display. The formula used is:

[0041] v=∫adt

[0042] Turn on the switch 23 of the laser radar device 2, and the laser emitting module 241 emits 16 laser beams. The emitted laser beams are refracted by the refractive mirror 1 242 and the refractive mirror 2 243 to form a detection surface. The motor 29 drives the telescopic rod 210 to move back and forth. The telescopic rod 210 is connected to the refractive mirror 1 242, thereby changing the range of the detection surface.
