When an external driving motor drives a winch to normally rotate, the winch winds and tightens the steel rope, then the steel rope drives a hoisted bridge member to lift upwards, because the steel rope can always prop against and squeeze with the conveying wheel 3 in the process of movement, the steel rope can drive the conveying wheel 3 to synchronously rotate under the action of friction force, the conveying wheel 3 rotates and drives the rotating shaft 2 to rotate, the permanent magnets 15 embedded in the side walls of the two ends of the rotating shaft 2 synchronously rotate, when the permanent magnets 15 are close to the magnetic blocks 18, because the polarities of the permanent magnets 15 and the magnetic blocks 18 are the same, the magnetic blocks 18 can seal and slide for a certain distance under the action of magnetic repulsion, and then hydraulic oil filled in the sliding groove 17 is squeezed into the rectangular cavity 22, so that the sliding plug 23 can seal and slide for a certain distance to the right inside the rectangular cavity 22 (as shown in fig. 6), and finally the maintenance oil on the right of the rectangular cavity 22 is squeezed into the unidirectional liquid outlet pipe 27 to flow, and finally the maintenance oil is sprayed out of the inside the spray heads 41 and adhered to the brush bristles 40, and the brush the side parts of the steel rope evenly, so that the service life of the steel rope is prolonged.
When the permanent magnet 15 is far away from the magnetic block 18, the magnetic block 18 slides in a reverse sealing way for a certain distance under the action of the first spring 49, and the sliding plug 23 slides in a reverse sealing way for a certain distance under the action of the tension spring 29, so that hydraulic oil at the left part of the rectangular cavity 22 is extruded and flows back into the liquid storage cavity 20 through the unidirectional return pipe 50, and in the reciprocating sealing sliding process of the sliding plug 23, as the sliding plug 23 has a certain thickness, the sliding plug 23 always abuts against the communicating part of the first unidirectional pipe 28 and the rectangular cavity 22 to generate a blocking effect, so that mineral oil cannot enter the first unidirectional pipe 28 to circulate.
When the external driving motor suddenly loses power in the hoisting and lifting process, the steel rope moves reversely at the moment, the falling speed of the steel rope driven by the bridge component is obviously accelerated, so that the rotating speed of the rotating shaft 2 driven by the conveying wheel 3 is accelerated, then the rotating speed of the permanent magnet 15 driven by the rotating shaft 2 is accelerated, the magnetic block 18 can rapidly and hermetically slide in the chute 17 under the action of magnetic repulsive force and the first spring 49, the hydraulic oil in the chute 17 is extruded into the rectangular cavity 22 through the unidirectional communicating pipe 21 when the magnetic block 18 slides in a rightward sealed manner (as shown in fig. 6), because the reciprocating sliding speed of the magnetic block 18 is accelerated, the pipe diameter of the unidirectional communicating pipe 21 is larger than the pipe diameter of the unidirectional return pipe 50, and then the hydraulic oil in the rectangular cavity 22 does not completely flow back into the rectangular cavity 20 in the process of keeping away from the magnetic block 18 by the permanent magnet 15, the magnetic block 18 pumps part of hydraulic oil from the inside of the liquid storage cavity 20 and then extrudes the hydraulic oil into the rectangular cavity 22, so that the inside of the rectangular cavity 22 continuously enters the hydraulic oil, the sliding plug 23 is further enabled to continuously move rightwards until the sliding plug 23 moves rightwards to the end of the stroke and no longer abuts against the communicating part of the first one-way pipe 28 and the rectangular cavity 22 to generate a blocking effect, then the hydraulic oil entering the inside of the rectangular cavity 22 enters the multi-joint pipe body 7 through the first one-way pipe 28 to circulate, then enters the spline groove 8 through the multi-joint pipe body 7, the rotary joint 6 and the round pipe 12 to circulate, the spline shaft 9 is pushed to slide downwards in a sealing way for a certain distance, the spline shaft 9 drives the cam 10 fixedly connected with the spline shaft to synchronously move downwards, so that the cam 10 moves to the position with the same height of the guide plate 37, and because the rotating shaft 2 drives the second conical wheel 5 to rotate through the first conical wheel 14 in the rotating process, the second conical wheel 5 drives the round shaft 48 to rotate, the round shaft 48 drives the spline shaft 9 and the cam 10 to rotate through the spline groove 8, the cam 10 drives the anti-falling plate 33 to rotate towards one side close to the steel rope through the adjacent guide plate 37 in the rotating process, the anti-falling plate 33 drives the round rod 31 to synchronously rotate, then the ratchet wheel 34 can prop against the pawl 32 to slide, and the pawl 32 can avoid the ratchet wheel 34 from reversing.
When the two anti-falling plates 33 synchronously rotate for a certain angle, under the cooperation of the cooperation blocks 42, the two anti-falling plates 33 drive the anti-falling blocks 36 to clamp and lock the steel rope through the driving plate 47, so that the steel rope is prevented from continuously falling down, and the anti-falling effect is achieved.
Then, after the hoisted bridge member is safely placed by means of the suspension arm, the magnetic spring 24 is electrified, the adjusting block 45 slides in the adjusting groove 44 for a certain distance, the adjusting block 45 drives the adjusting rod 46 and the pawl 32 to move in a direction away from the ratchet wheel 34 for a certain distance, the pawl 32 cannot limit the reverse rotation of the ratchet wheel 34, then the round rod 31 reversely rotates for a certain angle under the action of the torsion spring 35, and the anti-falling block 36 and the steel rope are separated from the clamping and locking state.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
