Example Embodiment

[0020] Such as Figure 1 ~ Figure 7 The double planetary drive lifting mechanism for a casting crane shown includes two sets of drive systems and a wire rope system composed of a fixed pulley group 3, a reel group 4, a steel wire rope 5 and a movable pulley group on a spreader. The driving system includes two electric motors 1, two working brakes 2, an emergency brake 6 and a reducer 7 with a planetary package. The motor 1 is connected to the reducer 7 through the coupling 10, the output shaft of the reducer 7 is connected to the reel coupling 14, the reel coupling 14 is connected to the reel group 4, and the reel group 4 is close to the reducer 7 Gear pair 8 is installed on one side. It is characterized in that the two sets of driving systems are rigidly connected together by a pair of gear pairs 8 installed on the reel set 4. The speed reducer 7 is driven by the motor 1, and the speed reducer 7 drives the steel wire rope system, and drives the lifting mechanism spreader to ...

Abstract

The invention discloses double planetary transmission hoisting mechanisms for a ladle crane, comprising two sets of driving systems and steel wire rope systems, wherein the steel wire rope systems are respectively composed of a fixed pulley block, a winding drum group, a steel wire rope and a movable pulley block on a lifting appliance; the driving systems respectively comprise two electromotors,two service brakes, an emergency brake and a reducer with a planetary packet; the electromotors are connected with a reducer by a coupling; an output shaft of the reducer is connected with the coupling of a winding drum; the coupling of the winding drum is connected with the winding drum group; and one side, which closes to the reducer, of the winding drum group is provided with a gear pair. The double planetary transmission hoisting mechanisms for a ladle crane is characterized in that two low-speed ends of the two sets of driving systems are rigidly connected by the gear pair; the output shafts of the electromotors are provided with the service brake respectively; and the emergency brake is connected with or arranged on a planet carrier shaft by a pair of overdrive gears. The double planetary transmission hoisting mechanisms for a ladle crane have the advantages of being simple in control and light in weight, improved safety, reduced cost, and being more convenient to maintain.

Description

technical field [0001] The invention relates to a hoisting mechanism of a crane, in particular to a hoisting mechanism of a double reducer type with a planetary package. Background technique [0002] The hoisting mechanism of existing cranes adopting planetary reducer has two types: planetary three reducer and planetary large reducer, see Image 6 , 7 . The two sets of driving systems of these two types of hoisting mechanisms have no rigid connection at the low-speed end, and emergency brakes and emergency brake operating status monitoring systems must be installed at the low-speed end. Thereby all there is following problem: 1, emergency brake is arranged on the low-speed end, and moment of moment is big, can produce huge impact to whole vehicle when misoperation. 2. The operating status of the emergency brake needs to be strictly monitored. The monitoring system equipped for this purpose has complex software and hardware configurations and requires high maintenance level...
