Abstract
The utility model discloses a manual/electric dual-purpose integrated hydraulic hoist which comprises a manual control part and an electric control part, wherein the manual control part and the electric control part are connected in parallel and arranged between an oil box and an oil cylinder of the hydraulic hoist; and the manual control part comprises a first oil filter, a manual hydraulic pump, a first overflow valve, a first pressure gauge, a first one-way valve, a manually operated directional valve and a first speed control valve. The hydraulic hoist disclosed by the utility model has the advantages that under the condition of no power supply, a product in a manual operation state also can work normally; when a power supply exists, the product can be switched to an electric operation state so as to work; and the two operation modes have no interference and no influence.
Description
Technical field
The utility model relates to a kind of headstock gear that in water conservancy, municipal engineering, is used to open and close gate, trashrack etc., is specifically related to a kind of manual and electric double-purpose integrated hydraulic hoists.
Background technology
Original integrated hydraulic hoists is a kind of headstock gear structure of mechanical electronic hydraulic integrated, and it is main body with the hydraulic cylinder, and it is overall that oil pump, motor, fuel tank, hydraulic control valve combine.Suddenly under the emergency case that has a power failure when the scene, or the field power supply condition be can't provide the time, and this product can't operate as normal, has greatly influenced safety, can't guarantee the work continuity of product.
Summary of the invention
The purpose of the utility model provides a kind of manual and electric double-purpose integrated hydraulic hoists, and through the configuration that improves equipment, coming provides power source to product; Thereby reach under the emergency case that product has a power failure suddenly at the scene; Or the field power supply condition be can't provide the time, through hand-operating device, and operate as normal.
The technical scheme that the utility model adopts is: a kind of manual and electric double-purpose integrated hydraulic hoists, comprise manual control part and electronic control section, and said manual control part and electronic control section are in parallel installed with between the fuel tank and oil cylinder of hydraulic hoist;
Said manual control part comprises first oil filter, hydraulic hand-pump, first overflow valve, first pressure meter, first one way valve, hand-operated direction valve and first flow speed control valve; One end of said first oil filter communicates with fuel tank through oil pipe; The other end is connected with hydraulic hand-pump; Hydraulic hand-pump is connected with first overflow valve and first one way valve respectively, is provided with first pressure meter between the hydraulic hand-pump and first overflow valve, and first one way valve is connected with hand-operated direction valve; Hand-operated direction valve is connected with oil cylinder, is provided with first flow speed control valve between hand-operated direction valve and the oil cylinder;
Said electronic control section comprises second oil filter, hydraulic pump, motor, second overflow valve, second pressure meter, second one way valve, solenoid operated directional valve and second flow speed control valve; One end of said second oil filter communicates with fuel tank through oil pipe; The other end is connected with hydraulic pump, and hydraulic pump is connected with motor, and hydraulic pump is connected with second overflow valve and second one way valve respectively; Be provided with second pressure meter between the hydraulic pump and second overflow valve; Second one way valve is connected with solenoid operated directional valve, and solenoid operated directional valve is connected with oil cylinder, is provided with second flow speed control valve between solenoid operated directional valve and the oil cylinder.
Operating principle is following: 1, under the condition that is having power supply to provide, hydraulic pump by motor driven after, oil suction from fuel tank.Fluid gets into hydraulic pump through oil filter, fluid in pump chamber from inlet low pressure to the pump discharge high pressure, get into chamber, a hydraulic cylinder left side through start-stop valve, choke valve, reversal valve, promote piston workbench moved right.At this moment, the oil in the right chamber of hydraulic cylinder flows back to fuel tank through reversal valve and oil return pipe.2, under the condition that does not have power supply to provide, hydraulic pump to system's fuel feeding, thereby makes the product operate as normal after being driven by hand gear.
Beneficial effect: the utility model has solved product under power free condition, and opening manual operation state also can operate as normal, when power supply, can switch to the work of electric operating state.Two kinds of operator schemes are not disturbed mutually, are independent of each other.
