Abstract

The utility model relates to an oil and electricity dual-purpose power crane for an automobile. The utility model is characterized in that on the base of a power system of an internal combustion engine [6] of an automobile, the utility model, a motor with a set of speed regulating switch controller [14] and a hydraulic pump [2] are connected to a position of a conversion valve [4] in parrel and respectively use the same hydraulic operating system of the crane, and the conversion valve is additionally arranged. When the motor [3] is used for power, high-pressure oil pipes [9], [10] are closed by the conversion valve [4], and thus, high-pressure oil pipes [11], [12] are communicated with high-pressure pipelines [7], [8]; thus, high-pressure oil generated by the hydraulic pump [2] is driven to flow to the operating system of the crane by the motor [3] which is under the action of the speed-regulating switch controller [14]; if users want to use the internal combustion engine [6] as the power, as long as the high-pressure pipes [11], [12] are closed by the conversion valve [4], and the high-pressure oil pipes [9], [10] are communicated with the high-pressure pipelines [7], [8], the crane can be operated normally.

Description

The dual-purpose power crane of automobile oil electricity
Affiliated technical field
The utility model relates to a kind of dual-purpose power crane of being made up of side by side automobile self internal combustion engine power plant and a cover electronic device of automobile oil electricity.
When car hosit promoted weight at present, power provided power by automobile self combustion engine.But because the fuel price height pollutes big.Both increase the working cost spending, can not protect environment again.
In order to overcome the deficiency of existing car hosit use self combustion engine, a kind of car hosit that the utility model provides, increase by a cover motor power transfer device exactly, be connected in parallel with the car combustion engine power system, when car hosit by internal combustion engine operation behind the work place, as long as power supply is arranged, energized at once is just replaceable combustion engine provides operation power by electrical motor.
The technical scheme that the utility model adopted is: in car hosit, combustion engine, power takeoff, Hydraulic Pump and high pressure fuel pipe are connected a change-over valve, insert speed control switch controller, electrical motor, Hydraulic Pump side by side and link to each other with change-over valve.When electrical motor was worked like this, the high pressure oil of generation entered in the high pressure fuel pipe of former internal-combustion engine system use by change-over valve, entered into the parts of the required high pressure oil of hoisting crane; And when using combustion engine, equally by change-over valve control, make high pressure oil enter crane hydraulic system and work on.
The beneficial effects of the utility model are can make electricity consumption that power is provided, cost-cutting, protection environment; Not influencing combustion engine again continues to use.
Concrete structure of the present utility model and application have following scheme drawing to be illustrated.
In the drawings 1, hydraulic reservoir, 2 and 5, Hydraulic Pump, 3, electrical motor, 4, change-over valve, 6, combustion engine, 7,8,9,10,11 and 12, high pressure fuel pipe, 13, power takeoff, 14, the speed control switch controller.
Insert Hydraulic Pump [2] with threeway in hydraulic reservoir [1] oil outlet pipe in former car hosit combustion engine [6] hydraulic efficiency pressure system, Hydraulic Pump [2] connects the electrical motor [3] that has speed control switch controller [14], electrical motor [3] is under the control of speed control switch controller [14] like this, high pressure oil [11], [12] that Hydraulic Pump [2] is discharged, through change-over valve [4], change-over valve [4] is closed pipeline [9], [10] of Hydraulic Pump [5], enter pressure piping [7], [8] identical with Hydraulic Pump [5], other work piece is constant in the hydraulic efficiency pressure system like this, and hoisting crane can have been worked as usual; And at car combustion engine [6] when being used as power, power takeoff [13] drives Hydraulic Pump [5], produces high pressure oil [9], [10], by change-over valve [4], closes high-pressure pipe [11], [12], and connects the path of [9], [10] and [7], [8]., high pressure oil just can flow in the original hydraulic system like this.Use combustion engine (6) or electrical motor (3) that power is provided very easily, make car hosit work.

Claims (5)

1, the utility model provides a kind of automobile oil electricity dual-purpose power crane, the original combustion engine of this hoisting crane [6], both made the whole mobile power of hoisting crane, make the Hydraulic for lifting load operation power again, power takeoff [13] is arranged, Hydraulic Pump [5] and hydraulic reservoir [1] connect with each Hydraulic for lifting load work piece, it is characterized in that: at hydraulic reservoir [1] the oil outlet pipe place of Hydraulic for lifting load part, connect a Hydraulic Pump that increases newly [2], connect with the electrical motor that has speed control switch controller [14] [3], Hydraulic Pump (2) and Hydraulic Pump (5) are discharged the pipeline (11) of high pressure oil, (12) and (9), (10) be connected in side by side on the change-over valve (4).So just can directly use oil or two kinds of different energy sources of electricity to replace and be used as power work.
2, according to the dual-purpose power crane of the described automobile oil electricity of claim 1, it is characterized in that increasing an electrical motor (3) that has speed control switch controller [14].
3, according to the dual-purpose power crane of the described automobile oil electricity of claim 1, it is characterized in that the Hydraulic Pump [2] that electrical motor (3) connects, the Hydraulic Pump [5] that drives with combustion engine [6] is connected on the change-over valve [4] side by side.
4, according to the dual-purpose power crane of the described automobile oil electricity of claim 1, it is characterized in that the high pressure oil that change-over valve [4] control is discharged by electrical motor [3] or combustion engine [6], flow to each shared Hydraulic for lifting load device, rather than the other side's Hydraulic Pump.
5,, it is characterized in that shared same set of hydraulic circuit and the Hydraulic for lifting load equipment on it according to the dual-purpose power crane of the described automobile oil electricity of claim 1.
