The piston 9 is limited by a limit block arranged on the inner cavity wall of the second oil cylinder 7 and is always positioned above a connecting port of the first oil guide pipe 3, the second oil guide pipe 6 and the second oil cylinder 7, the piston of the second piston rod 17 is also limited by a limit block arranged on the inner cavity wall of the third oil cylinder 14 and is always positioned above a connecting port of the first oil guide pipe 3 and the third oil cylinder 14, the possibility that the connecting port is blocked by the piston is eliminated due to the design, when the first oil guide pipe 3 and the second oil guide pipe 6 feed oil to the second oil cylinder 7, the piston 9 can overcome the elastic force of the first spring 8 and be jacked up by oil pressure, and when the guide rod 10 feeds oil to the third oil cylinder 14, the piston of the second piston rod 17 can be jacked up by oil pressure.
Wherein, the slide rail 15 is equipped with a limiting plate towards the one end of lifting machine body 2 for slide to 16 carries on spacingly, avoids 16 slide rails 15 to break away from.
Wherein, dog 18 bottom is equipped with the outside bottom plate that extends, when guide arm 10 and loop bar 12 kayser, lifting machine body 2 does not have the projection to the bottom plate of dog 18 in vertical downward direction, when guide arm 10 and loop bar 12 are release state and slider 16 slided to the limiting plate department of slide rail 15, lifting machine body 2 possesses the projection to the bottom plate of dog 18 in vertical downward direction, because behind guide arm 10 and the 12 unblock of loop bar, because damping spring 11's elastic force can promote loop bar 12, third hydro-cylinder 14 and slider 16 slide along slide rail 15, until the limiting plate contact of slider 16 with slide rail 15, the bottom plate of dog 18 also removes the below of lifting machine body 2 thereupon, lifting machine body 2 is when vertical downstream, just can push down the bottom plate of dog 18.
Wherein, when the rotating cantilever 44 is kept in a horizontal state, the hoisting machine body 2 always has a projection on the rotating cantilever 44 in the vertical direction, so that the hoisting machine body 2 can be contacted with the rotating cantilever 44 when moving up and down in the vertical direction, as shown in fig. 7, when the hoisting machine body 2 is contacted with the rotating cantilever 44 from top to bottom, the rotating cantilever 44 is pressed to rotate clockwise, because the fixed block 43 is limited and supported below the rotating cantilever 44, the rotating cantilever 44 can drive the rotating wheel 41 to rotate together clockwise, if the hoisting machine body 2 moves from bottom to top, the hoisting machine body 2 can drive the rotating cantilever 44 to rotate anticlockwise, but the rotating cantilever 44 is not limited at this time, then the rotating cantilever 44 rotates at this time and can not drive the rotating wheel 41 to rotate, so the rotating cantilever 44 can be lifted up by a certain angle along with the ascending of the hoisting machine body 2, and when the hoisting machine body 2 is separated from the rotating cantilever 44, the rotating cantilever 44 is pivoted back to the original horizontal position by gravity.
The working principle and the using process are as follows:
two sets of buffer systems are arranged on each floor at the inner side of the support frame 1 and are respectively positioned at the left side and the right side of the elevator body 2, as shown in fig. 2, the position relationship between the two sets of buffer systems arranged on a single layer and the elevator body 2 is shown, under normal conditions, when the elevator body 2 moves up and down along the support frame 1 at a normal speed, the unlocking of the guide rod 10 and the loop rod 12 is not triggered, because when the elevator body 2 moves down at the normal speed, although the elevator body 2 can press the rotating wheel 41 to rotate, under the normal speed condition, the rotating speed of the rotating wheel 41 is slower, the retraction speed of the first piston rod 51 pushed by the connecting rod 45 is slower, and under the premise that the retraction speed of the first piston rod 51 is slower, the hydraulic oil in the first oil cylinder 5 can be slowly released along the second oil guide pipe 6, so that the pressure of the hydraulic oil in the inner cavity of the first oil cylinder 5 on the inner wall of the first oil cylinder 5 is not large, insufficient to allow the block 133 to descend against the force of the second spring 135;
however, when the elevator body 2 suddenly falls, the instantaneous impact speed of the elevator body 2 is fast, so that the rotating speed of the rotating wheel 41 is increased, and the retraction speed of the first piston rod 51 is increased, so that the first piston rod 51 quickly pushes oil in the inner cavity of the first oil cylinder 5, but because the inner diameters of the communication port of the second oil guide pipe 6 and the first oil cylinder 5 and the pipe diameter of the second oil guide pipe 6 are limited, hydraulic oil in the first oil cylinder 5 cannot be instantly discharged along the second oil guide pipe 6, so that the oil pressure in the first oil cylinder 5 is suddenly increased, the sealing block 133 also bears the oil pressure, and the oil pressure overcomes the elastic force of the second spring 135, so that the lock rod 134 descends;
when the clip strip 1341 finally and completely passes through the first clipping hole 101 and the second clipping hole 121, the loop bar 12 loses the limiting effect caused by the clip strip 1341 being located in the rectangular through groove of the first clipping hole 101 and the second clipping hole 121, so the loop bar 12 can slide along the guide rod 10 by the elastic force of the damping spring 11, so the third oil cylinder 14 and the slider 16 move together until the slider 16 contacts with the limiting plate of the slide rail 15, the bottom plate of the stopper 18 also moves below the elevator body 2, when the elevator body 2 moves vertically and downwards, the bottom plate of the stopper 18 can be pressed, the falling elevator body 2 is supported by the bottom plate of the stopper 18, the elevator body 2 can press the second piston rod 17 to move downwards, the second piston rod 17 compresses the oil cavity of the third oil cylinder 14 and presses the hydraulic oil into the second oil cylinder 7 along the first oil guide pipe 3, and the pipe diameter of the first oil guide pipe 3 is limited, so that the hydraulic oil in the third oil cylinder 14 cannot be drained instantly, and a part of the retained hydraulic oil can provide supporting force to reduce the speed of the elevator body 2, thereby realizing the buffering effect until the hydraulic oil in the third oil cylinder 14 is completely drained.
