Embodiment Construction

[0015] Please refer to figure 2 , which is a schematic top view of a preferred embodiment of the hoisting system of the crane of the present invention. Such as figure 2 As shown, the hoisting system 2 of the crane of the present invention includes two sets of "motor-reducer-drum" transmission mechanisms 100 and 200 that are independent and opposite to each other. The transmission mechanism 100 includes a motor 11 , a motor braking device 12 , a planetary reducer 18 and a reel 14 connected to the planetary reducer 18 by transmission. In addition, the transmission mechanism 100 also includes a tilting motor 15 a and a braking device 15 b for the tilting motor. The planetary reducer 18 is a multi-stage reducer, including a planetary package 17 . The transmission mechanism 200 includes a motor 21 , a motor braking device 22 , a planetary reducer 28 and a reel 24 connected to the planetary reducer 28 by transmission. In addition, the transmission mechanism 200 also includes a ...

Abstract

The invention discloses a lifting system of a crane, which is used for lifting or descending a lifted object with two lifting points. The lifting system comprises a first transmission mechanism and a second transmission mechanism. The first transmission mechanism and the second transmission mechanism are in transmission connection through a synchronizer and have the same structures. Each transmission mechanism comprises a motor, a tipping motor, a winding drum and a planetary reducer, wherein the motor and the tipping motor are respectively in transmission connection with the planetary reducer and respectively transmit power to the planetary reducer; the planetary reducer is in transmission connection with the winding drum and transmits the power to the winding drum; the winding drum is provided with a rope; and one end of the rope is fixed to the winding drum and the other end of the rope is connected to one lifting point of the lifted object. According to the lifting system, after one set of transmission mechanism is braked, the other set of transmission mechanism can continuously output the rotating speed to realize the tipping action of the lifted object; meanwhile, the safetyis improved and the service life of a transmission system is prolonged.

Description

technical field [0001] The invention relates to a hoisting system applicable to a crane for hoisting a large hoisting object to the upper limit position and realizing tipping. Background technique [0002] A crane is an electromechanical device used to lift vertically or vertically and move heavy objects horizontally. Some cranes perform a tipping action after vertically suspending the lifting object with two lifting points to high altitude, so the lifting system of this type of crane needs to be equipped with two sets of independent "motor-reducer-drum" transmission mechanisms. Each set of transmission mechanism acts on a lifting point of the lifting object. When rising, two sets of "motor-reducer-reel" transmission mechanisms run synchronously to hoist the lifting object to the upper limit position. When tipping over, one set of transmission mechanisms is braked by the brake, and then the other set of transmission mechanisms continues to run , to raise or lower one of th...
