Abstract
The utility model belongs to the technical field of wheeled tractor hoists and work-over rigs, in particular to a static hydraulic driving device of the hoist system for wheeled tractor hoists and work-over rigs. The utility model is characterized in comprising eight parts, that is, a power supply, an oil pump, a slippage pump, a check valve, a hydraulic motor, a hoist, an oil tank, and an oil pipeline. The power supply is connected with the oil pump which is connected with the hydraulic motor through the oil pipeline; the hydraulic motor is connected with the hoist; the check valve is arranged on the oil pipeline; the slippage pump is connected with the oil tank through the oil pipeline. The utility model has the advantages of simple structure, low failure rate, convenient use and maintenance, high degree of automation, high transmission efficiency and high work efficiency.
Description
One, technical field: the utility model belongs to wheeled tractor hoist and well repairing machine technical field, relates in particular to the hydrostatic transmission of a kind of wheeled tractor hoist and well repairing machine hoisting system.
Two, background technique: the dynamic structure of the hoisting system of existing wheeled tractor hoist and well repairing machine is motor-main clutch-gearbox-commutation angle case-cylinder speed reducer or chain transmission-winch, and employing motor-torque converter-commutation angle case-cylinder speed reducer or chain transmission-winch structure are also arranged.The former has the high advantage of mechanical efficiency, but really has the transmission complexity, rate of fault height, deficiencies such as maintenance difficult.The latter has adopted the electric liquid shift valve can carry out remote-controlled operation, though simple to operate, also exist ineffective defective.
Three, summary of the invention:
The purpose of this utility model is to design a kind of hydrostatic transmission that is used for wheeled tractor hoist and well repairing machine hoisting system at the prior art above shortcomings.Advantages such as this device has the transmission efficiency height, and is simple in structure, and operation system is simplified, and speed governing is convenient, uses maintenance easy, and rate of fault is low.
Its technological scheme is: the feature of the hydrostatic transmission of this wheeled tractor hoist and well repairing machine is that it is made up of power source, oil pump, slippage pump, one-way valve, oil hydraulic motor, winch, fuel tank, oil transport pipeline eight parts, power source links to each other with oil pump, oil pump links to each other with oil hydraulic motor by oil transport pipeline, oil hydraulic motor links to each other with winch, one-way valve has two, it is located on the oil transport pipeline, and slippage pump links to each other with fuel tank by oil transport pipeline.Power source is the power source of oil pump, and it can be a motor, also can be diesel engine or petrol engine and other power plant.Oil pump is the device that pressure unit is provided to the pressure oil in the oil transport pipeline, slippage pump causes in order to prevent in closed system that oil pump and oil hydraulic motor leakage of oil and oil pump feed are not enough that emptying phenomenon and compensation oil pump and oil hydraulic motor instantaneous displacement are uneven and is provided with, slippage pump is except giving system's repairing, can also change the fluid of working connection, make system cools, one-way valve is the device that makes the pressure oil one-way flow in the oil transport pipeline, and it is provided with two.Oil hydraulic motor is the control winch and provides the device of power to it, it be controlled to be electrichydraulic control, thereby improved the automaticity of handling.Winch is the winch on wheeled tractor hoist and the well repairing machine, no longer here stating more.Fuel tank is the fuel tank of deposit pressure oil, and it adds to pressure oil in the oil transport pipeline by slippage pump and goes.Use the medium power source by the oil pump power taking, exert pressure for the pressure oil in the oil transport pipeline, pressure oil transmission pressure is to oil hydraulic motor and form a closed circuit.Because oil hydraulic motor inserts in the drum shaft, so whole system just can be by the variation of oil pump, thereby drive oil hydraulic motor and winch rotates, and the clockwise and anticlockwise and the lifting work of realization winch.This device is suitable for using on wheeled tractor hoist and the well repairing machine.
The advantage of this device mainly contains: 1, simplified operation system, owing to be the positive displacement speed governing, hydraulic system is electrichydraulic control, and its speed governing is convenient, has improved the automaticity of handling; 2, simplify the structure, easy to connect, rate of fault is low, maintenance and easy to use; 3, device adopts all-hydraulic transmission, so the transmission efficiency height, working efficiency also improves greatly.
Four, description of drawings:
Fig. 1 is the main TV structure schematic representation of the hydrostatic transmission of wheeled tractor hoist and well repairing machine.
Among Fig. 1: 1, power source; 2, oil pump; 3, slippage pump; 4, one-way valve, it has two, but installation direction is opposite; 5, oil transport pipeline; 6, oil hydraulic motor; 7, winch; 8, fuel tank.Power source 1 is the power source of oil pump 2, and the power of slippage pump 3 also can be provided by power source 1, and one-way valve 4 is provided with two, and it is located on the oil transport pipeline 5, in the oil transport pipeline 5 pressure oil is housed, and pressure oil transmits pressure and uses.Oil hydraulic motor 6 is to drive winch 7, and fuel tank 8 is the fuel reserve tanks for oil transport pipeline 5 supplementary pressure oil.
Five, embodiment:
Fig. 1 can be used as a specific embodiment structural representation of the present utility model.This device is used for wheeled tractor hoist, and power source adopts diesel engine, and the power of slippage pump 3 is also provided by diesel engine, and other all is prior art, and is easy to implement.
