Abstract
The utility model discloses a double-control power unit of a wheelchair. The double-control power unit of the wheelchair comprises a center valve block, an oil tank and a motor, wherein the oil tank and the motor are arranged at the two ends of the center valve block respectively. A gear pump connected with an oil suction pipe and an oil return pipe are arranged on the end face, in the oil tank, of the center valve block, two oil inlet ways are arranged in the center valve block, a one-way valve is arranged on one side wall of the center valve block and communicated with the first oil inlet way, the other side wall of the center valve block is connected with a transition block, a manual pump is arranged on the transition block and is communicated with the second oil inlet way, and a manual electromagnetic valve is arranged on the side wall of the center valve block and is communicated with an oil return way. According to the double-control power unit of the wheelchair, the two oil ways are arranged on the center valve block, one oil inlet way is connected with the gear pump and the one-way valve, the other oil inlet way controls a hydraulic oil way through the manual pump, the manual electromagnetic valve is arranged on the side wall of the center valve block and is communicated with the oil return way, therefore, two ways of automatic lifting and manual lifting of a wheelchair platform are achieved, and the requirements in different situations are met.
Description
Technical field
The utility model relates to hydraulic system power unit field, is specifically related to tricycle for the disabled dual control power unit.
Background technique
The advantage such as that hydraulic transmission has is lightweight, volume is little, motional inertia is little, reaction velocity is fast, and hydraulic pressure can bear very large pressure, so power resources when hydraulic power unit often is applied to various vehicle operation.For the design of tricycle for the disabled lifting platform, the application of hydraulic power unit is more convenient for limbs that incomplete personnel's operation is arranged, if but just in case, under power shortage state, also will bring great inconvenience to the handicapped people.
Summary of the invention
The technical problems to be solved in the utility model is to provide tricycle for the disabled dual control power unit, realizes take electronic control as main, and manually controlling is auxiliary mutual supplementary control mode, realizes tricycle for the disabled lifting platform function.
The utility model is achieved through the following technical solutions:
Tricycle for the disabled dual control power unit, comprise the centre valve piece, be fixed in fuel tank and the motor at centre valve piece two ends, be provided with gear pump and the return tube that is connected with fuel sucking pipe on the end face of centre valve piece in fuel tank, establish the twice in-line in described centre valve piece, centre valve piece sidewall is provided with one-way valve and is communicated with in-line one, another sidewall of centre valve piece connects transition block, and transition block is provided with hand pump and is communicated with in-line two.
The further improvement project of the utility model is that described centre valve piece sidewall is provided with manual solenoid valve and is communicated with oil circuit.
The utility model further improvement project is that described manual solenoid valve is the plugged electric magnet valve.
The utility model further improvement project is that described centre valve piece is aluminium alloy compression casting valve piece.
The utility model compared with prior art, has following obvious advantage:
One, centre valve piece of the present utility model arranges the twice in-line, lead up to gear pump, one-way valve, hydraulic circuit is controlled by hand pump in another road, centre valve piece sidewall is provided with manual solenoid valve and is communicated with oil circuit, two kinds of modes of tricycle for the disabled platform automatic lifting and hand-operated lifting have been realized, to meet the needs of different situations.
Two, centre valve piece of the present utility model adopts the casting of fine aluminum alloy precision to form, superior performance, and solenoid valve adopts the plugged electric magnet valve, reduces space, easy to assembly, simple to operate, strongly professional.
