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. 1-5, a cable reel paying-off speed reducing mechanism for cable laying and installation comprises a base 1, a first support column 2 is fixedly connected to the top of the base 1, a first rotating shaft 3 is movably connected to the top of the first support column 2, a wire reel 4 is fixedly connected to the outer side of the first rotating shaft 3, a cable is wound inside the wire reel 4, a conveyor belt 5 is connected to the outer side of the first rotating shaft 3 in a transmission manner, a second rotating shaft 6 is connected to one side, away from the first rotating shaft 3, of the conveyor belt 5 in a transmission manner, the first rotating shaft 3 and the second rotating shaft 6 are connected in a transmission manner through the conveyor belt 5, a disc 7 is fixedly connected to the outer side of the second rotating shaft 6, a second support column 8 is fixedly connected to the top of the second support column 8 in a movable manner, the top of the second support column 8, the inside of the ring 9 is movably connected with a clamping joint 10, the outer side of the disc 7 is fixedly connected with a limiting block 11, the number of the clamping joint 10 and the limiting block 11 is eight, the distance between the two clamping joints 10 is larger than the width of the limiting block 11, the width of the clamping joint 10 is smaller than the distance between the two limiting blocks 11, the inside of the disc 7 is provided with a chute 12, the distance from the left side of the chute 12 to the center of the disc 7 is smaller than the distance from the right side of the chute 12 to the center of the disc 7, the left side of the inside of the chute 12 is fixedly connected with a spring I13, one side of the spring I13, which is far away from the chute 12, is fixedly connected with a metal ball I14, the right side of the inside of the chute 12 is fixedly connected with a metal ball II 15, the metal ball I14 is provided with positive charge, the metal ball II 15 is provided with negative charge, the, the inside of the inner groove 16 is movably connected with an electrorheological body 18, the electrorheological body 18 is solid under the condition of electrification and liquid under the condition of non-electrification, the main materials of the electrorheological body 18 are composed of gypsum, lime and carbon powder, and the electrorheological body 18 is in electrical connection with the first metal ball 14 and the second metal ball 15.
The working principle is that when the rotation speed of the cable reel is too high, the cable is wound inside the wire spool 4, the rotation speed of the wire spool 4 is too high, the wire spool 4 is fixedly connected to the outer side of the first rotating shaft 3, the rotation speed of the first rotating shaft 3 is too high, the first rotating shaft 3 and the second rotating shaft 6 are in transmission connection through the conveyor belt 5, the rotation speed of the second rotating shaft 6 is too high, the disc 7 is fixedly connected to the outer portion of the second rotating shaft 6, the rotation speed of the disc 7 is too high, the inclined groove 12 is formed in the disc 7, the first spring 13 is fixedly connected to the left side of the inner portion of the inclined groove 12, the first metal ball 14 is fixedly connected to one side of the first spring 13, which is far away from the center of the disc 7, the first metal ball 14 moves in a direction far away from the center of the disc 7 under the action of centrifugal force, and the distance from the left side of the inclined groove 12 to the center, therefore, the first metal ball 14 moves to the right side of the inclined groove 12, and the second metal ball 15 is fixedly connected to the right side inside the inclined groove 12, so that the first metal ball 14 touches the second metal ball 15 when the cable reel rotates too fast.
Because the first metal ball 14 has positive charge, the second metal ball 15 has negative charge, the current variant 18 is solid when electrified and liquid when not electrified, the main materials of the current variant are gypsum, lime and carbon powder, the current variant 18 is electrically connected with the first metal ball 14 and the second metal ball 15, the current variant 18 can be changed from liquid state to solid state at the moment, because the current variant 18 is movably connected with the inside of the inner groove 16, the two sides of the spring 17 are respectively and fixedly connected with the inner groove 16 and the clamping joint 10, the current variant 18 can extrude the clamping joint 10 to the outside of the inner groove 16 at the moment, because the inner groove 16 is arranged inside the ring 9, the ring 9 is sleeved outside the disc 7, the clamping joint 10 can move towards the disc 7 at the moment, because the limiting block 11 is fixedly connected with the outside of the disc 7, the quantity of the clamping joint 10 and the limiting block 11 is eight, and the distance between the two clamping joints 10 is larger than the width of the limiting block 11, the width that joint 10 was connected to the card is less than the distance between two stopper 11, so joint 10 and stopper 11 can block this moment, again because the top of support column two 8 and the back fixed connection of ring 9, so disc 7 can be blocked by ring 9 this moment, the speed of disc 7 can reduce in the twinkling of an eye this moment, further make the speed of axis of rotation two 6 reduce in the twinkling of an eye, axis of rotation one 3 can reduce at speed under the frictional force condition of conveyer belt 5 this moment, further make the slew velocity of cable drum reduce, effectual control cable slew velocity has been reached, prevent that the cable drum from rotating too fast effect. Because the speed of the disc 7 is reduced, the first metal ball 14 is separated from the second metal ball 15 under the action of the first spring 13, the current transformer 18 is uncharged, the clamping connector 10 is separated from the limiting block 11 under the action of the second spring 17, the disc 7 can normally rotate, and the cable reel can be decelerated circularly for many times, so that the cable reel cannot suddenly stop in the deceleration process, and the effect of preventing the cable from being damaged by pulling in the deceleration process of the cable reel is achieved.
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.
