Abstract
The utility model relates to the technical field of oil supply of a drive device-a hydraulic type push rod which makes reciprocating straight line movement, particularly an electric manual dual-purpose hydraulic push rod. The utility model comprises an electrohydraulic oil supply system which is composed of an oil tank, an electrical motor, a dual action gear pump, a liquid control one-way valve, and an electromagnetic overflow valve, wherein a high pressure ball valve is arranged between the electrohydraulic oil supply system and an oil cylinder, and a set of manual hydraulic oil supply systems are connected between the high pressure ball valve and the oil cylinder. The utility model adopts a design proposal of multipath and multisystem and thus even under the condition of power shortage, the hydraulic push rod can immediately enable the manual method to go on supplying oil to the oil cylinder, and consequently the working stability and reliability of the hydraulic push rod can be raised.
Description
Technical field
The utility model relates to the drive unit of linear reciprocating motion---the fuel feeding technical field of hydraulic type push rod.
Background technique
The hydraulic type push rod is applicable to back and forth and pushes away, roping moving, or rise, descend, or the place of clamping working substance, and can carry out remote, high-altitude and the location at risk is concentrated or program control, the electric hydaulic oil supply system that the conventional hydraulic push rod is made up of fuel tank, motor, double-direction gearpump, Pilot operated check valve, electromagnetic relief valve, in case occur to have a power failure, whole electric hydaulic oil supply system just can not fuel feeding, hydraulic push rod can not be worked, and ordinary production, processing are caused the series influence.
The model utility content
The utility model purpose is a kind of electric-hand driven two-purpose hydraulic push rod that also can proper functioning under powering-off state of design.
The utility model comprises the electric hydaulic oil supply system of being made up of fuel tank, motor, double-direction gearpump, Pilot operated check valve, electromagnetic relief valve, between electric hydaulic oil supply system and oil cylinder, high-pressure ball valve is set, between high-pressure ball valve and oil cylinder, is connected one group of hand-hydraulic oil supply system.
This model utility has adopted the design proposal of multichannel, multisystem, makes hydraulic push rod under the situation of short of electricity, can enable manual mode immediately and continues to the oil cylinder oil-feed, and the stability of hydraulic push rod work and reliability are improved.The utlity model has following advantage:
1, the utlity model has manual, electronic double system, can be by the hydraulic hand-pump proper functioning under the situation of outage.Avoided the loss that causes owing to the power failure equipments cisco unity malfunction.And under normal circumstances manual system and electromotion system can work independently respectively and are independent of each other.
2, the utility model is the product of mechanical-electrical-hydraulic integration full-closed structure, and under bad working environment, not dust suction is not intake, and is convenient to install, safeguard.
3, the utility model flexible movements, stable working can effectively cushion external impact, and Stroke Control is accurate.
4, of the present utility modelly push away, pulling force and operating rate can stepless on demand adjustment, energy-saving safe, under thrust or pulling force and speed same case, it is energy-conservation more than 30% that power consumption is compared product of the same type.
5, the utility model is an independent system, and is simple to operate, invests for a short time, and has duplex and makes system, can guarantee that work is perfectly safe, and this push rod is desirable Power Drive Unit.
Above-mentioned hand-hydraulic oil supply system comprises hydraulic hand-pump and manual three-position four-way valve, the oil inlet end of hydraulic hand-pump is connected with fuel tank, the other end is connected with the P end of manual three-position four-way valve, manually the T of three-position four-way valve end is connected with fuel tank, and manually A, the B of three-position four-way valve end is connected with two closed chamber of oil cylinder respectively.
