Abstract

The invention discloses a manual and electric dual-purpose integrated hydraulic hoist. The manual and electric dual-purpose integrated hydraulic hoist 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 are arranged between an oil tank and a 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 check valve, a manual reversing valve and a first speed regulating valve. The manual and electric dual-purpose integrated hydraulic hoist can also work normally by turning on a manual operation mode under the condition that a power supply is not provided, and can switch to an electric operation mode when the power supply is provided, wherein the two operation modes are not interfered with each other or influence each other.

Description

The manual and electric double-purpose integrated hydraulic hoists
 
Technical field
The present invention relates in water conservancy, municipal engineering, be used for a kind of headstock gear of open-close sluice gate, trashrack etc., be 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 take hydraulic cylinder as main body, 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 work, and has greatly affected safety, can't guarantee the work continuity of product.
Summary of the invention
The purpose of this invention is to provide a kind of manual and electric double-purpose integrated hydraulic hoists, by the configuration that improves equipment, provide 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, by hand-operating device, and normal operation.
The technical solution used in the present invention is: a kind of manual and electric double-purpose integrated hydraulic hoists, comprise manual control part and electronic control section, and described manual control part and electronic control section are installed in parallel between the fuel tank and oil cylinder of hydraulic hoist;
Described manual control part comprises the first oil filter, hydraulic hand-pump, the first overflow valve, the first pressure meter, the first one way valve, hand-operated direction valve and the first flow speed control valve, one end of described the first oil filter communicates with fuel tank by oil pipe, the other end is connected with hydraulic hand-pump, hydraulic hand-pump is connected with the first overflow valve and the first one way valve respectively, be provided with the first pressure meter between hydraulic hand-pump and the first overflow valve, the first one way valve is connected with hand-operated direction valve, hand-operated direction valve is connected with oil cylinder, is provided with the first flow speed control valve between hand-operated direction valve and the oil cylinder;
Described electronic control section comprises the second oil filter, hydraulic pump, motor, the second overflow valve, the second pressure meter, the second one way valve, solenoid operated directional valve and the second flow speed control valve, one end of described the second oil filter communicates with fuel tank by oil pipe, the other end is connected with hydraulic pump, the hydraulic pressure Pump and Electromotor connects, hydraulic pump is connected with the second overflow valve and the second one way valve respectively, be provided with the second pressure meter between hydraulic pump and the second overflow valve, the second one way valve is connected with solenoid operated directional valve, solenoid operated directional valve is connected with oil cylinder, is provided with the second flow speed control valve between solenoid operated directional valve and the oil cylinder.
Operating principle is as follows: 1, under the condition that is having power supply to provide, hydraulic pump by Motor Drive after, oil suction from fuel tank.Fluid enters hydraulic pump through oil filter, and fluid from entrance low pressure to the pump discharge high pressure, enters the left chamber of hydraulic cylinder by start-stop valve, choke valve, reversal valve in pump chamber, and pushing piston moves right workbench.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, after hydraulic pump is driven by hand gear, to system's fuel feeding, thereby make the product normal operation.
Beneficial effect: the invention solves product under power free condition, open manual operation state and also can work, when power supply is arranged, can switch to the work of electric operating state.Two kinds of operator schemes do not interfere with each other, and are independent of each other.
