By providing the detection mechanism 5 and the disengagement mechanism 7, the detection mechanism 5 can detect the breakage of any traction rope, and through the action of the disengagement mechanism 7, the transmission between the traction wheel 24 and the transmission shaft 231 is invalidated, so that the traction wheel 24 stops rotating, and the traction wheel 24 is always in a stationary state, thereby improving the safety level of the reluctance motor traction machine and reducing the probability of accidents.

The outer walls of the two sliding sleeves 381 are fixedly installed with L-shaped connecting rods 382, ​​and one end of the two L-shaped connecting rods 382 is fixedly connected to the upper surface of the push plate 37. By arranging the guide rods 38, the sliding sleeve 381 and the L-shaped connecting rod 382, ​​the guide rods 38, the sliding sleeve 381 and the L-shaped connecting rod 382 can guide the push plate 37 in the vertical direction, so that the push plate 37 can maintain the vertical lifting.

[0038] The detection mechanism 5 includes an L-shaped fixing frame 51, one end of the L-shaped fixing frame 51 is fixedly installed on the other side of the reduction gear box 2, and a U-shaped frame 52 is fixedly installed on the other end of the L-shaped fixing frame 51.

A second guide sleeve 54 is fixedly installed on one end of the plurality of fixing rods 55, and the plurality of second guide sleeves 54 are inclinedly arranged. By arranging the first guide sleeve 53 and the inclined second guide sleeve 54, before the assembly of the elevator, the traction rope on the traction wheel 24 passes through the first guide sleeve 53 and the second guide sleeve 54 to be connected with the counterweight device of the elevator car, and the traction rope passing through the first guide sleeve 53 and the second guide sleeve 54 is in a tensioned state.

[0039] A plurality of spring rods 56 are fixedly installed on one side of the U-shaped frame 52, one end of which is fixedly connected to the outer wall of a first guide sleeve 53, and a plurality of moving rods 57 are fixedly installed on the outer walls of the first guide sleeves 53.

The brake plate 6 and the conical block 61 are inclined. By setting the spring rod 56, when the traction rope breaks, the spring rod 56 extends, and the spring rod 56 can push the first guide sleeve 53 to move horizontally. The first guide sleeve 53 can make the moving rod 57 move horizontally. The moving rod 57 can push the pushing groove 59 to make the push rod 58 move horizontally. The push rod 58 can make the brake plate 6 and the conical block 61 move horizontally.

[0040] A first guide groove 582 is provided at one end of the L-shaped equipment frame 581, and a first guide block 583 is slidably installed at one end of the first guide groove 582. The other end of the push rod 58 is fixedly connected to one side of the first guide block 583. By setting the first guide groove 582 and the first guide block 583, the first guide block 583 can guide the push rod 58 in the horizontal direction, so that the push rod 58 can keep moving in the horizontal direction.

[0041] The disengagement mechanism 7 includes a hollow connecting rod 71, which penetrates the traction wheel 24 and is fixedly connected to the traction wheel 24. A lead screw 72 is rotatably installed at one end of the L-shaped equipment frame 581, and a threaded sleeve 73 is fixedly installed at one end of the hollow connecting rod 71. One end of the lead screw 72 penetrates the threaded sleeve 73 and is threadedly connected to the inner wall of the threaded sleeve 73. Two card slots 74 are formed at one end of the transmission shaft 231 away from the worm gear 23, and two card blocks 75 are fixedly installed at the other end of the hollow connecting rod 71. The card blocks 75 and the inner wall of the card slot 74 slide together. The screw 72 is dynamically connected. By driving the screw 72 to rotate, the screw 72 can make the hollow connecting rod 71 move horizontally through the threaded sleeve 73, and the hollow connecting rod 71 can make the traction wheel 24 move horizontally synchronously. By setting the slot 74 and the block 75, when the worm gear 23 rotates, the worm gear 23 can make the traction wheel 24 rotate synchronously through the transmission shaft 231, the block 75 and the hollow connecting rod 71. At the same time, when the screw 72 rotates, the block 75 can guide the hollow connecting rod 71 in the horizontal direction, so that the hollow connecting rod 71 keeps moving in the horizontal direction.

[0042] A second guide groove 76 is provided on the L-shaped equipment frame 581, and two second guide blocks 77 are slidably installed at one end of the second guide groove 76. Support rods 78 are fixedly installed on the two second guide blocks 77, and arc-shaped support rings 79 are fixedly installed at one end of the two support rods 78. The edge of the traction wheel 24 is in movably contact with the inner walls of the two arc-shaped support rings 79. By arranging the second guide groove 76, the second guide block 77, the support rod 78 and the arc-shaped support ring 79, the second guide groove 76, the second guide block 77 and the support rod 78 can guide the traction wheel 24 in the horizontal direction through the arc-shaped support ring 79, so that the traction wheel 24 keeps moving in the horizontal direction. At the same time, the arrangement of the arc-shaped support ring 79 does not conflict with the rotation of the traction wheel 24.

[0043] The other end of the lead screw 72 is fixedly installed with a transmission gear 8. By setting the transmission gear 8, when the conical block 61 moves horizontally and is inserted into the tooth groove of the transmission gear 8 and stays in the tooth groove, the conical block 61 can make the transmission gear 8 rotate and then stop, and the transmission gear 8 can make the lead screw 72 rotate. The lead screw 72 makes the hollow connecting rod 71 move horizontally through the threaded sleeve 73. During the horizontal movement of the hollow connecting rod 71, the clamping block 75 gradually disengages from the clamping groove 74. After complete disengagement, the transmission of the transmission shaft 231 fails. By setting an inclined conical block 61, the conical block 61 can horizontally enter the tooth groove of the transmission gear 8, and the transmission gear 8 cannot push the conical block 61 to move horizontally in the opposite direction during the rotation. Therefore, after the conical block 61 stops moving, the transmission gear 8 can be stopped through the tooth groove of the transmission gear 8.

[0044] Working principle: When assembling the reluctance motor traction machine, the multiple traction ropes passing around the traction wheel 24 pass through the multiple first guide sleeves 53 and the multiple second guide sleeves 54 respectively, and are connected to the counterweight device of the elevator car, and the other ends of the multiple traction ropes are connected to the elevator car;

[0045] When any one of the traction ropes breaks, the traction rope is separated from the corresponding first guide sleeve 53. At this time, a spring rod 56 stretches and causes a moving rod 57 to move horizontally through a first guide sleeve 53. A moving rod 57 causes a push rod 58 to move horizontally through a corresponding push groove 59. The push rod 58 causes the brake plate 6 and the conical block 61 to move horizontally synchronously. The conical block 61 gradually enters the tooth groove of the transmission gear 8 during the horizontal movement and remains stationary in the tooth groove. During this process, the conical block 61 drives the transmission gear 8 to rotate, and the transmission gear 8 causes the lead screw 72 to rotate. The lead screw 7 The threaded sleeve 73 is used to make the hollow connecting rod 71 move horizontally. During the horizontal movement of the hollow connecting rod 71, the two clamping blocks 75 are gradually disengaged from the corresponding clamping grooves 74 and completely disengaged. At this time, the hollow connecting rod 71 is disengaged from the transmission shaft 231, the traction wheel 24 stops rotating and stops moving, and the elevator car stops lifting, thereby conveniently realizing the static protection after any one of the traction ropes breaks, so that the elevator car can stop in time, avoiding the breakage of any one of the traction ropes causing the successive breakage of multiple traction ropes, improving the safety level of the reluctance motor traction machine, and reducing the probability of elevator accidents;

[0046] During daily operation, the maintenance personnel turn on the drive motor 41, and the drive shaft of the drive motor 41 rotates the rotating rod 42. The rotating rod 42 causes the driving shaft 44 to revolve around the axis of the rotating rod 42 through the rotating disk 43. The driving shaft 44 causes the pushing handle 4 and the rotating shaft 39 to cause the pushing disk 37 to reciprocate and rise and fall. The pushing disk 37 causes the piston disk 36 to reciprocate and rise and fall synchronously. The piston disk 36 continuously pressurizes the lubricating oil in the oil storage tank 31 during the reciprocating lifting process. The squeezed lubricating oil is discharged downwardly to the worm 22 and the worm wheel 23 through the first oil outlet 321 and multiple second oil outlet holes 322, so as to lubricate the worm 22 and the worm wheel 23, thereby conveniently realizing the automatic lubrication of the worm 22 and the worm wheel 23, reducing the working intensity of the maintenance personnel, and improving the transmission efficiency of the worm 22 and the worm wheel 23, while improving the service life of the worm 22 and the worm wheel 23.
