Example five:
as shown in fig. 8, the leg 1 includes a first portion 13 and a second portion 14, a base 16 is detachably disposed at a lower end of the first portion 13, an adjusting motor 7 is disposed in the base 16, a first rotating plate 71 is fixedly connected to a top end of the first portion 13, a second rotating plate 72 is disposed on an upper end surface of the first rotating plate 71, a third rotating plate 73 is disposed on an upper end surface of the second rotating plate 72, an upper end surface of the third rotating plate 73 is fixedly connected to one end of a spring 74, and the other end of the spring is connected to the second portion 14. The adjusting motor 7 can drive the first rotating piece 71 to rotate, the first rotating piece 71 drives the second rotating piece 72 to rotate through friction force, the second rotating piece 72 drives the third rotating piece 73 to rotate through friction force, namely, friction force exists between the first rotating piece 71 and the second rotating piece 72 when the first rotating piece 71 and the second rotating piece 72 rotate relatively, the friction force can be from the upper end surface of the first rotating piece 71 or from the lower end surface of the second rotating piece 72, and the second rotating piece 72 and the third rotating piece 73 are also the same; the third rotating piece 73 rotates the spring 74, and the spring 74 rotates the second portion 14. This structure also can realize this hoisting machine's rotation.
Preferably, the maximum rotational range of the spring 74 is 360 degrees.
When the hook has goods, the pressure of the weight can be transmitted to the second part 14, the second part can apply pressure to the spring, the spring can be compressed, the pressure on the spring can be transmitted to the second rotary piece through the third rotary piece, and when the transmitted friction force is large enough to a certain step, the second rotary piece and the third rotary piece stop rotating. When the force is removed or relieved, the spring rebounds gradually, the friction force between the second rotating piece and the third rotating piece is reduced, and the work can be recovered.
The spring can cushion partial pressure stress, and the spring is in coordination with other structural component interact, can provide torsion to enable to rotate and kick-back the convenience, can send overweight warning through temporary stop work moreover, behind the overweight elimination, can resume the operation by oneself, very facilitate the use.
The structure is simple, the cost is very low, and the manufacture or the combination is convenient. Moreover, the hoisting machine can also rotate, so that goods in different directions can be grabbed or placed, the hoisting machine can also be stopped at any time when the goods are overweight, and the practicability is extremely strong.
The invention can also be provided with sensors, single-chip microcomputers and the like, thereby realizing more intelligent regulation and control of each link. The type of sensor, the arrangement and connection of the sensor and the single chip, etc. can be set according to the prior art.
