The invention relates to a working principle of an electric drive hand-operated hybrid elevator, which comprises the following specific steps:
in the normal operating state, the drum 5 is driven by the power source 3, and in the emergency state, is switched to the hand-operated driving mode.
In a normal working state, the power source 3 transmits power to the first sun gear 5.2 through the output shaft 5.1, and the position of the first gear ring 5.3 is fixed, so that the first sun gear 5.2 drives the first planet gear 5.4 to revolve in the same direction and rotate in the opposite direction, and the first planet carrier 5.5 and the first sun gear 5.2 are driven to rotate in the same direction and reduce in speed. After the speed of the NGW planetary transmission mechanism is reduced, the first planetary gear is transmitted to the second sun gear 5.7 through the first planetary gear 5.5, at the moment, the worm gear pair is in a self-locking state, the third planetary gear 5.10 and the third gear ring 5.11 are fixed and do not rotate, so that the two-stage planetary gear 5.9 is fixed and does not rotate, the second sun gear 5.7 can only drive the second planetary gear 5.8 to reversely rotate, and further drive the second gear ring 5.6 to rotate, and after the speed of the NGWN planetary transmission mechanism is reduced, the second gear ring 5.6 is transmitted to the roller 5 to drive the roller 5 to rotate. Finally, the output rotating speed of the roller 5 is the product of the reduction ratio of the NGW planetary transmission mechanism and the NGWN planetary transmission mechanism, and the large reduction ratio electric drive is realized through planetary transmission.
In the process of rotating the roller 5, the outer gear ring driving pair 4 synchronously rotates, so that the transmission gear II 9a and the transmission gear I2 c are driven to rotate, the transmission gear II 9a drives the guide shaft 10a to rotate together, the transmission gear III 9b rotates along with the guide shaft 10a, the transmission gear IV 9c is driven to rotate together through the transmission of the chain 9d, the transmission gear IV 9c drives the rope conveying roller 8 to rotate, the linear speed of the rope conveying roller 8 is slightly higher than that of the roller 5 through proportioning, and tensioning of the steel wire rope 7 is ensured. Further, during the rotation of the drum 5, the spherical protrusion of the wire-discharging moving member 10b relatively moves in the spiral groove of the drum 5, and the wire-discharging moving member 10b is linearly moved along the guide shaft 10a by the rotation of the drum 5. And, transmission gear one 2c drives compression roller axle 2b and compresses tightly roller one 2a and rotate together, compresses tightly roller two 2d and also can rotate relative cylinder 5, compresses tightly roller one 2a and compresses tightly the rotation of roller two 2d, can guarantee the inseparable arrangement or the smooth and easy output of wire rope 7, and arrange the removal in-process of silk moving part 10b, guarantee that wire rope 7 arranges neatly, does not bite the line to play the adjustment to wire rope 7 output direction through arranging silk moving part 10b, defeated rope roller 8 and fixed axle 11, thereby guarantee to accomplish defeated rope or promote the operation smoothly.
When the power source 3 is a double-output servo motor, the rollers 5 at two sides are driven to rotate simultaneously, so that the rotation synchronization of the rollers 5 at two sides is ensured. When the power source 3 is a single-output servo motor, the roller 5 on one side is driven to rotate, power is transmitted to the first transmission gear 2c, the second transmission gear 9a and the outer gear driving pair 4 on the other side by the first outer gear driving pair 4, the first transmission gear 2c and the second transmission gear 9a on one side, and the roller 5 is driven to rotate by the outer gear driving pair 4 on the other side, so that double-side synchronous rotation is realized. The weight of the whole machine is reduced in the single-side driving mode compared with the double-side driving mode.
In an emergency state, the power source 3 is in a power failure or fault state, the output shaft 5.1 and the sun gear one 5.2 are fixed and do not rotate, and the NGW planetary transmission mechanism does not play a role. At this time, power is manually input through the hand input shaft 6, is transmitted to the worm gear pair through the bevel gear pair, then drives a planet wheel III 5.10 in the NGWN planetary transmission mechanism to rotate around the center of a gear ring III 5.11 through the worm gear pair, and drives a two-stage planet carrier 5.9 to rotate together, at this time, a sun wheel II 5.7 does not rotate, so that a planet wheel II 5.8 rotates, drives a gear ring II 5.6 to rotate, is transmitted to a roller 5 on the side through the gear ring II 5.6, drives the roller 5 on the side to rotate, and is transmitted to the roller 5 on the other side through an outer gear ring driving pair 4, a transmission gear I2 c and a transmission gear II 9 a. At this time, the output rotation speed of the roller 5 is the product of the bevel gear pair, the worm gear pair and the NGWN planetary transmission mechanism, and the large reduction ratio manual driving is realized through the bevel gear pair, the worm gear pair and the NGWN planetary transmission mechanism, so that the rope conveying or lifting operation is completed.
