Problems solved by technology

[0002] At present, the main type of home elevator market is the home hydraulic elevator. It is characterized by safety, but its disadvantages are that the hydraulic system is complex, the hydraulic oil generates heat when it is working, the oil temperature is unstable, the failure rate is high and it is not easy to find out, and the hydraulic pump station works. Loud noise, low efficiency, poor comfort and slow speed during elevator lifting
The existence of these problems is not suitable for the needs of the high-end market and high-end crowd

Abstract

The invention relates to a numerically-control hydraulic muting type household elevator. An elevator car is connected with a single-acting oil cylinder through a steel wire rope. A hydraulic oil way structure connected with the single-acting oil cylinder is specifically characterized in that a servo motor is connected with a hydraulic pump, an oil inflow / outflow opening in the lower end of the hydraulic pump is connected with an oil tank, and an oil inflow / outflow opening in the upper end of the hydraulic pump is connected with an oil opening of the single-acting oil cylinder through a proportional flow control valve. The oil way between the single-acting oil cylinder and the proportional flow control valve is provided with a hydraulic pressure control switch. The domestic elevator is stable and comfortable in operation, no abnormal feeling exists in the lifting process, noise is extremely low, operation is safe and reliable, energy is saved, and the numerically-control hydraulic muting type household elevator can especially meet the requirements of the high-end market.

Description

technical field [0001] The invention relates to a numerically controlled hydraulic silent type home elevator, which is used for home hydraulic elevators in low-rise villas or bungalows. Background technique [0002] At present, the main type of home elevator market is the home hydraulic elevator. It is characterized by safety, but its disadvantages are that the hydraulic system is complex, the hydraulic oil generates heat when it is working, the oil temperature is unstable, the failure rate is high and it is not easy to find out, and the hydraulic pump station works. Loud noise, low efficiency, poor comfort and slow speed during elevator lifting. The existence of these problems is not suitable for the needs of the high-end market and high-end crowd. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a numerically controlled hydraulic silent type home elevator, which has the characteristics of extremely stable and comfortab...
