Technical Field

[0001] The present invention relates to the technical field of lifting drive mechanisms, in particular to a lifting drive mechanism for an elevator. Background Art

[0002] The lifting drive mechanism of the elevator is used to automatically control the lifting of the elevator. The elevator is a kind of lifting equipment composed of a walking mechanism, a hydraulic mechanism, an electric control mechanism, and a supporting mechanism. The hydraulic oil is formed into a certain pressure by the vane pump, and enters the lower end of the cylinder through the oil filter, flameproof electromagnetic reversing valve, throttle valve, hydraulic control check valve, and balance valve, so that the piston of the cylinder moves upward and lifts heavy objects. The return oil at the upper end of the cylinder returns to the oil tank through the flameproof electromagnetic reversing valve, and its rated pressure is adjusted by the relief valve. The pressure gauge reading is observed through the pressure gauge. It is an integral part of the platform and the equipment, motors, cables and other auxiliary equipment used to operate them.
