Docking state detection
As shown in fig. 5, in order to detect the butt state of the hook 2, particularly to detect the rotation of the hook body 21, a butt state detection component is provided on the hook 2; the butt joint state detection assembly comprises a detection disc 4, a first state detection sensor 44 and a second state detection sensor 45; the detection plate 43 is fixed to the rotation shaft 22 of the hook 21 and rotates with the rotation of the hook 21; the first state detection sensor 44 and the second state detection sensor 45 are attached to the outside of the detection plate 43, and are coupled to the detection plate 43 to detect the position.
The first state detection sensor 44 and the second state detection sensor 45 may be contact microswitches or non-contact hall proximity switches; as shown in fig. 6, the detection plate 43 is a circular plate fixed on the rotating shaft 22 and extending beyond the plate surface, and is provided with a first protrusion 431 and a second protrusion 432, forming a double-sided cam structure; for convenience of installation and adjustment, the first protrusion 431 and the second protrusion 432 are symmetrically disposed, and the first state detecting sensor 44 and the second state detecting sensor 45 are symmetrically disposed accordingly. As shown in fig. 6, the first state detection sensor 44 and the second state detection sensor 45 are contact microswitches, and are respectively provided with a first detection head 441 and a second detection head 451; when the protruding structure of the detecting plate 43 rotates to the position of the first status detecting sensor 44 or the second status detecting sensor 45, the protruding mechanism presses the first detecting head 441 and/or the second detecting head 451 to give a corresponding detecting signal, so as to indicate that the hook 21 reaches a corresponding rotation angle position.
The hook body 21 is normally divided into an unclamping state, a process state and a locking state, which correspond to fig. 6 (a), (b) and (c); the hook body 21 rotates from an unlocking state to a locking state, the rotation angle is 90 degrees, namely, from the state shown in fig. 6 (a), the first protrusion 431 is separated from the first detection head 441, then from the state shown in fig. 6 (b), 2 detection heads are not pressed by a protrusion mechanism and have no signal, and finally, from the state shown in fig. 6 (c), the other side of the first protrusion 431 is contacted with the second detection head 451, and a position signal is given; the arc angle of the first protrusion 431 is about 90 °.
When the hook body 21 is screwed out to a locking state, the hook body 21 is perpendicular to the frame body of the rectangular frame 1, so that the size of the extending body is the largest; when the limit structure is not arranged in the lifting hook driving device 3, the hook body 21 is over-rotated, namely, the state shown in fig. 6 (d) is achieved, at the moment, the size of the extending body is reduced due to over-rotation of the hook body 21, the butt joint surface is reduced, the safety coefficient is reduced, and therefore an alarm signal needs to be given, the lifting is suspended, and the inspection is carried out. At this time, the second projection 432 is rotated toward the first detection head 441, and the first state detection sensor 44 and the second state detection sensor 45 are simultaneously in a trigger state. Thus, the second projection 432 has an arc angle of less than 90, and is generally disposed between 60 and 70.
When the hook is rotated reversely from the locking state to the unlocking state, the second protrusion 432 will contact the second detection head 451 to give a signal when over-rotation occurs, the first state detection sensor 44 and the second state detection sensor 45 are simultaneously in the triggering state, and at this time, the state of the hook driving device 3 is also properly checked to prevent over-rotation from occurring, which causes dead angle of the connecting rod and affects subsequent normal operation.
The normal detection of the rotating butt joint state of the hook body 21 can be realized by arranging the first bulge 431; further, by arranging the second protrusion 432, the over-rotation state is also detected, and the butt joint is ensured to be in the most reliable state.
The normal rotation angle state is generally detected by adopting an encoder, particularly an absolute angle encoder, but the encoder is precise, high in use cost and easy to damage; the contact type microswitch is adopted for detection, the use cost is low, the industrial microswitch is extremely high in reliability, the current butt joint state can be judged through detection of analog switching values, and the efficiency is high.
Although embodiments of the present invention have been shown and described, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art without departing from the scope of the present invention.
