[0002] The traction sheave is the rope pulley on the traction machine, also called the traction rope sheave or driving rope sheave. It is a device for transmitting traction power for the elevator. It uses the friction between the traction wire rope and the rope groove on the traction wheel rim to transmit power. It is installed on the worm gear shaft in the reducer. If it is a gearless traction machine, it is installed next to the brake and on the same axis as the motor shaft and brake shaft.

The base frame 101 is fixed to the reserved machine position by bolts. The diamond-shaped interference arm 109 is tilted on the base frame 101, and the driving tooth arm 104 is meshed with the main driving gear 113. In the initial state, through the pushing of the pushing spring 111, the two first driving gears 106 are in a meshing and synchronous internal rotation structure on the first end frame 105. Through the meshing of the two second driving gears 108, the diamond-shaped interference arm 109 forms an elastically outward-extending interference arm structure on the interference frame assembly 100.

[0029] In a preferred embodiment, please refer to Figure 6 and Figure 7The follow-up reverse cleaning roller assembly 200 includes a U-shaped frame 201, an L-shaped frame 208 is fixedly arranged below the U-shaped frame 201 through a fixed back rod 213, a horizontal slide groove 209 and a bottom round table 210 are arranged on the bottom frame of the L-shaped frame 208, and a toggle gear 212 is rotatably arranged on the top frame of the L-shaped frame 208, a second pulley 211 is fixedly arranged on the toggle gear 212, a belt 214 is sleeved on the second pulley 211, a third bevel gear 205, a second bevel gear 204, a first pulley 215 and a first bevel gear 202 are rotatably arranged on the U-shaped frame 201, a resistance wheel 203 is coaxially fixedly arranged on the first bevel gear 202, and a cleaning roller 203 is coaxially fixedly arranged on the third bevel gear 205 06. The fourth bevel gear 207 and the fifth bevel gear 216 are fixedly arranged on both sides of the first pulley 215, the third bevel gear 205 and the cleaning roller 206 are rotatably connected to one end of the U-shaped frame 201 through a shaft, the first pulley 215 is rotatably connected to the other end of the U-shaped frame 201 through a shaft, the second bevel gear 204 and the first bevel gear 202 are rotatably connected to the top of the U-shaped frame 201 through a shaft, the first bevel gear 202 is meshed with the fifth bevel gear 216, the fourth bevel gear 207 is meshed with one end of the second bevel gear 204, the other end of the second bevel gear 204 is meshed with the third bevel gear 205, the belt 214 is sleeved on the first pulley 215 and the second pulley 211, and a rubber cushion is arranged on the outer ring of the abutment wheel 203.

[0030] In a preferred embodiment, please refer to Figure 8 The monitoring component 300 includes a monitoring bin 301 and an L-shaped toggle arm 306. A ball bin 302 is arranged in the monitoring bin 301, and a fulcrum rod 304 is rotatably arranged on the monitoring bin 301. A monitoring camera probe 303 is arranged at one end of the fulcrum rod 304, and a toggle end gear 305 is fixedly arranged at the other end of the fulcrum rod 304. A toothless tooth 310 and a toggle tooth 309 are arranged at the top of the L-shaped toggle arm 306, and a toggle arm end plate 307 and a reset spring 308 are arranged at the bottom of the L-shaped toggle arm 306. The monitoring camera probe 303 rotates in the ball bin 302, and the L-shaped toggle arm 306 slides in the horizontal slide groove 209. The reset spring 308 is pressed against the monitoring camera probe 303. It touches between the bottom truncated table 210 and the end plate 307 of the toggle arm, the toggle teeth 309 at the top of the L-shaped toggle arm 306 mesh with the toggle end gear 305, and the toggle teeth 309 at the top of the L-shaped toggle arm 306 mesh with the toggle end gear 212. In the initial state, the toggle arm end plate 307 is pushed by the reset spring 308, and the toggle teeth 309 form an engaging toggle force on the toggle end gear 305. At this time, the monitoring camera head on the monitoring camera probe 303 is rotated out of the ball warehouse 302 to form a static collection monitoring structure, and the toggle end gear 305 is rotatably set on the L-shaped frame 208, and the monitoring warehouse 301 is fixed on the L-shaped frame 208.

[0031] In actual use, when it is necessary to monitor the wear of the traction wheel, the electromagnet 102 is powered off, and the push spring 111 forms a downward thrust on the driving tooth arm 104 through the contact end plate 112. During the downward sliding of the driving tooth arm 104, due to the meshing of the driving tooth arm 104 and the main driving gear 113, the main driving gear 113 drives a first driving gear 106 to rotate inwardly on the first end frame 105. At this time, the two meshing first driving gears 106 rotate inwardly synchronously, and cooperate with the meshing of the two second driving gears 108. At this time, the diamond-shaped contact arm 109 is in the contact frame assembly 1 00, that is, at this time, the follower reverse cleaning roller assembly 200 and the monitoring assembly 300 are both extended to the working position of the traction wheel 400, and the friction wheel 203 is in conflict with one end of the traction wheel 400. In the initial state, the reset spring 308 pushes the toggle arm end plate 307, and the toggle teeth 309 form an engaging toggle force on the toggle end gear 305. At this time, the monitoring shooting head on the monitoring camera probe 303 is rotated out of the ball bin 302 and forms a static collection monitoring structure. In this way, the monitoring and shooting of the wear of the traction wheel 400 is realized.

[0032] On the basis of the above, when the diamond-shaped resistance arm 109 is extended, the resistance wheel 203 is in resistance against one end of the traction wheel 400, and the cleaning roller 206 is located below the traction wheel 400. When the traction wheel 400 rotates, since the resistance wheel 203 is in resistance against one end of the traction wheel 400, the traction wheel 400 forms a driven pulling force on the resistance wheel 203. At this time, the first bevel gear 202 rotates. Since the first bevel gear 202 is meshed with the fifth bevel gear 216, the fourth bevel gear 207 is meshed with one end of the second bevel gear 204, and the other end of the second bevel gear 204 is meshed with the third bevel gear 205, the belt 214 is sleeved on the first pulley 215 and the fifth bevel gear 216. On the second pulley 211, when the first bevel gear 202 rotates, through the conversion of the above-mentioned meshing relationship, when the traction wheel 400 rotates, the top of the cleaning roller 206 and the bottom of the traction wheel 400 form a counter-rotating follower cleaning roller structure. In this way, when the traction wheel 400 rotates, through this driven drive and reverse cleaning, the wheel body at the bottom of the traction wheel 400 can be cleaned to avoid the presence of worn iron filings, thereby avoiding affecting the monitoring and shooting of the monitoring camera probe 303. On the other hand, through this iron filing cleaning, the adhesion of iron filings on the traction wheel 400 is avoided, thereby avoiding the wear of the acceleration wire rope when it is used on the traction wheel 400.

[0033] On the basis of the above, that is, when the traction wheel 400 rotates, the cleaning roller 206 forms a counter-rotating follower cleaning roller structure under the traction wheel 400. In order to prevent the cleaned iron filings from adhering to the lens of the monitoring camera probe 303, when the traction wheel 400 rotates, the first pulley 215 drives the second pulley 211 and the toggle gear 212 to rotate through the belt 214, and the toggle gear 212 forms an engaging toggle force on the L-shaped toggle arm 306 by toggle teeth 309. At this time, the L-shaped toggle arm 306 slides on the L-shaped stand 208 and compresses the reset spring 308. During the sliding process of the L-shaped toggle arm 306, the toggle teeth 309 form a driving force on the monitoring camera probe 303 through the toggle end gear 305. The measuring camera probe 303 is rotated to be hidden in the ball bin 302. In this way, the monitoring component 300 can dynamically hide the wear of the traction wheel on the follow-up reverse cleaning roller assembly 200 to avoid the adhesion of cleaned iron filings to the lens of the monitoring camera probe 303. It should be noted that when the L-shaped toggle arm 306 continues to slide and when the toothless tooth 310 is located below the toggle end gear 305, the rotation of the first pulley 215 no longer generates a driving force for the toggle end gear 305. At this time, the monitoring camera probe 303 is completely hidden in the ball bin 302. That is, when the ball bin 302 is hidden in place, even if the first pulley 215 continues to rotate, it will not affect the dynamic hiding of the monitoring camera probe 303 when monitoring the wear of the traction wheel.

[0034] On the basis of the above, when the traction wheel 400 stops rotating, the reset spring 308 is reset, and the L-shaped toggle arm 306 is reset. During the reset process of the L-shaped toggle arm 306, the monitoring camera head of the monitoring camera probe 303 is rotated out of the ball chamber 302 to prepare for the subsequent static collection and monitoring of the traction wheel 400.

[0035] On the basis of the above, when there is no need to monitor the wear of the traction wheel and to carry out follow-up cleaning of the traction wheel, the electromagnet 102 is energized. At this time, the electromagnet 102 pushes the driving tooth arm 104 to the top through the strong magnet 103. When the driving tooth arm 104 slides to the top, the two first driving gears 106 and the two second driving gears 108 on the interference frame assembly 100 rotate outward synchronously. At this time, the diamond-shaped interference arm 109 is in the inner retracted arm structure. At this time, the follow-up reverse cleaning roller assembly 200 and the monitoring assembly 300 are evacuated from the traction wheel 400 station, thereby avoiding meaningless traction wheel wear monitoring and follow-up cleaning of the traction wheel at the traction wheel 400 station.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
