Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4, a rotary disc safety self-locking device for a deep well rescue device includes a main shaft 1, wherein the main shaft 1 is fixedly connected with an output end of an external motor. The whole structure is provided with kinetic energy by an external motor, and the whole equipment is driven to operate by the main shaft 1.
An electromagnet 2 is fixedly connected inside the main shaft 1, and the magnetic pole of the electromagnet 2 is opposite to the shifting piece 3. When the electromagnet 2 is energized, the attraction of the electromagnet 2 to the paddle 3 is exerted to the maximum.
The surface of the outer ring of the main shaft 1 is rotatably connected with a shifting sheet 3, the lower end of the shifting sheet 3 is fixedly connected with a spring 4, and the bottom end of the spring 4 is fixedly connected to the surface of the main shaft 1.
The outer ring of the main shaft 1 is rotatably connected with a rotating hub 5, and the rotating hub 5 is mutually clamped with the shifting piece 3 through sawteeth 6 arranged on the surface of the inner ring. When the main shaft 1 rotates along the direction opposite to the poking sheet 3, the poking sheet 3 is connected with the sawteeth 6 in a clamping manner to drive the rotating roller 5 to rotate.
The sawtooth 6 has been seted up on the inner circle surface of commentaries on classics hub 5, and the outer lane of commentaries on classics hub 5 encircles and has cup jointed lifting rope 7, and the top fixedly connected with rings 8 of lifting rope 7, the outer lane fixedly connected with electric coil 9 of commentaries on classics hub 5, mutual electric connection between current variant 13 and the electric coil 9.
The outer ring of the rotating hub 5 is fixedly connected with a sliding groove 10, the sliding groove 10 is rotatably connected with a rotating shaft 11 in the groove, a clamping block 12 is movably sleeved on the outer ring of the rotating shaft 11, ten sliding grooves 10, ten rotating shafts 11, ten clamping blocks 12 and ten current transformers 13 are respectively arranged, and the ten sliding grooves, the ten rotating shafts, the ten clamping blocks and the ten current transformers are uniformly distributed by taking the main shaft 1 as a circle center. The multiple cartridges 12 are designed to improve the safety and safety of the entire device.
The inner circumferential surface of the latch 12 and the outer circumferential surface of the rotation shaft 11 are respectively provided with a serration 6 structure. The serration 6 is constructed to facilitate the hardened current transformer 13 to fix the relative position between the rotation shaft 11 and the latch 12.
The inner ring of the clamping block 12 is provided with an electrorheological body 13, and the electrorheological body 13 is mainly made of gypsum, lime, carbon powder, olive oil and water. When the electrorheological fluid 13 is energized, its texture becomes hard.
The side end of the sliding chute 10 is fixedly connected with a magnetic block 14, and the magnetic block 14 is located at the right center of the sliding chute 10. When the stopper 17 does not contact the latch 12, the latch 12 is influenced by the magnetic block 14 to be located at the middle position of the slide slot 10.
The outer ring of the rotating hub 5 is sleeved with a safety ring 15, the inner part of the safety ring 15 is fixedly connected with a magnetic strip 16, and the surface of the inner ring of the safety ring 15 is fixedly connected with a stop block 17.
The working principle is as follows: the whole structure is provided with kinetic energy by an external motor, and the whole equipment is driven to operate by the main shaft 1. Because plectrum 3 joint is on changeing the sawtooth 6 of hub 5, drives the hub synchronous revolution when main shaft 1 pivoted, twines lifting rope 7 and promotes rings 8, will be pulled up by the rescue personnel. During the rescue ascent, although the electric coil 9 rotates relative to the magnetic strip 16 and cuts the magnetic induction line, an induced current is generated, but the generated induced current does not change the texture of the current variant 13 enough to influence the operation of the whole structure due to the too slow rotating speed.
If in the process of pulling up the rescued person, the lifting rope 7 is wound and released by the rotating hub 5 due to factors such as too small power of a motor or exhaustion of the rescued person, the rescued person rapidly falls when waiting for the lifting ring 8 under the influence of gravity and pulls out the lifting rope 7 from the outer ring of the rotating hub 5 again, at the moment, the electric coil 9 on the rotating hub 5 rotates at a high speed relative to the magnetic strip 16 on the outer ring of the safety ring 15 and generates a large induced current, after the electric coil is introduced into the current variant 13, the current variant 13 becomes hard in texture and fixes the relative position between the clamping block 12 and the rotating shaft 11, wherein the hardened current variant 13 is convenient for further stabilizing the relative position between the structures by the inner ring of the clamping block 12 and the outer ring of the rotating shaft 11 through the sawtooth 6 structure, and the clamping block 12 is ensured. And the fixture block 12 which cannot rotate obstructs the relative rotation between the rotating hub 5 and the safety ring 15 through the fixture block 17, thereby achieving the effect of safety self-locking for the quick falling of the fixture block.
When the rotating hub 5 and the safety ring 15 rotate normally, the latch 12 can rotate freely, and when the latch contacts the stop 17, the latch does not block the stop. When the current transformer 13 is electrified, the latch 12 is attracted to the middle position of the sliding chute 10 due to the action of the magnetic block 14, so that the latch 12 is in a position capable of effectively blocking the stop 17 at the moment when the current transformer 13 is electrified.
When 7 release rings 8 through the lifting rope, only need to switch on 2 electro-magnet, plectrum 3 is adsorbed, spring 4 is compressed, plectrum 3 no longer the joint change the sawtooth 6 of hub 5, change hub 5 and main shaft 1 can relative rotation this moment, lifting rope 7 is because rings 8's action of gravity is pulled downwards, it winds as figure 1 anticlockwise rotation to drive to change hub 5, the length of release lifting rope 7 can be by the free operation of circular telegram time, when the electric current that lets in electro-magnet 2 is shut off, plectrum 3 is owing to spring 4's automatic kick-back of effect and joint change hub 5 again, stop rings 8's release, with this purpose of realizing convenient release lifting rope 7 and rings 8.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
