Abstract

The invention relates to a novel double-motor serial-parallel automatic switching device, which comprises a motor main control valve bank, a motor serial-parallel switching valve bank, a motor I and a motor II, wherein the motor serial-parallel switching valve bank consists of a two-way plugging valve I, a two-way plugging valve II, a two-way plugging valve III, an electromagnetic reversing valve and a shuttle valve, and the motor main control valve bank comprises a reducing valve, a main reversing valve, a balance valve, a safety valve, a passive cable laying valve and an oil compensation retaining valve. The novel double-motor serial-parallel automatic switching device has a simple structure, is convenient to operate and control, is reliable to work, can save the cost, and has remarkable economic benefit.

Description

Technical field [0001] The invention relates to a ship winch speed regulating system, in particular to a novel dual-motor series-parallel automatic switching device. Background technique [0002] At present, all kinds of ship winches should have the function of "heavy load low speed, light load high speed", and their functions are realized by the high and low speed switching of the variable motor, that is, the motor displacement is changed through the motor variable mechanism to change The output torque and speed of the motor. [0003] The Chinese Patent Authorization Announcement Number is CN 100374735C and the authorized announcement date is March 12, 2008. The invention patent discloses a skid-mounted electro-hydraulic proportional speed control system, including a two-way variable pump, a two-way variable motor and a two-way variable pump connected in series. Two skid-mounted electro-hydraulic proportional speed regulating valves between the circuit formed by the two-way varia...
