Embodiment
[0096] This example is used on a slewing tower crane with a pointed flat jib, the details are as follows:
[0097] see Figure 7 , In this embodiment, the hook of the tower crane includes: a hook 1, an obstacle distance sensor 2, a monitoring device 3 for the plane geometric dimension of the hanging object, and the weight sensor of the hanging object is placed inside the hook.
[0098] The internal structure of hanging object plane geometric dimension monitoring device 3 is as follows: figure 2 , 3 As shown, the driving motor 4 is fixed on the shell 6 by bolts, and the motion form is transmitted to the central helical gear 11 through the helical gear. The motion transmission of the crank rocker arm mechanism 10 drives the crank to move at a uniform speed in a circle. The ultrasonic sensor 5 is installed at the bottom of the rocker.
[0099] The measurement principle of the hanging object plane geometric dimension monitoring device 3 is, as Image 6 As shown, in the ultras...
