Abstract
The invention provides a method for detecting the rotating speed of a suction dredge rimer. A rotary signal acquisition device acquires a rotating speed signal of a motor to obtain the rotating speed of the rimer; a rotating speed signal picker and the rotary signal acquisition device are respectively positioned in two totally independent closed spaces; and the rotating speed signal picker and the rotary signal acquisition device are relatively fixed and cannot do relative displacement during use. In the method for detecting the rotating speed of the suction dredge rimer, the rotating speed signal picker picks a rotating rate parameter signal of the rotary signal acquisition device, so data obtained by the detection method has higher sensitivity, interference resistance is strong, water tightness is high, the method adapts to underwater working conditions, convenient installation, maintenance and construction is guaranteed and a rotating speed data electronic signal can be output in real time. The method has the advantages that practicability is high, the method is easy to implement, a detection result is accurate and rotating speed data can be output in real time.
Description
Technical field
The present invention relates to the technical field of Marine engineering, is that a kind of data are highly sensitive, antijamming capability strong, the cutter suction dredger reamer rotating speed detection method of real-time output speed data specifically.
Background technology
The reamer of cutter suction dredger is one of most important power output block of cutter suction dredger; the reamer rotary speed data is directly connected to the operating efficiency, mechanical load, soil property of cutter suction dredger etc., and the detection of cutter suction dredger reamer rotating speed is to improving operating efficiency, protection reamer, protection ship machinery, sum up construction method under the different soil property situations, realizing that dredging automation is most important.
The reamer power of most of cutter suction dredger is selected oil motor for use, oil motor is installed in the front portion of crane span structure usually, about 3-4 rice, oil motor need be operated in 2-25 rice under water apart from the distance of reamer, because the rotation of reamer causes a large amount of silt to be wrapped in oil motor.Present oil motor manufacturer does not all have accordingly speed detector under water.Most of shipyard adopts and install gear ring additional on mangler shaft, installs sensor additional in the crane span structure appropriate location, picks up the reamer tach signal by relative motion between gear ring and the sensor.Because near the bad working environments environment the reamer very easily damages sensor.This situation causes the vicious circle of shipyard endless " fault-report for repairment-guarantee to keep in good repair-fault ", so some shipyard does not just install the reamer speed probe additional; Even a lot of shipowners no longer adhere to installing additional the reamer speed probe.
Summary of the invention
The technical problem to be solved in the present invention provides that a kind of data are highly sensitive, antijamming capability is strong, the cutter suction dredger reamer rotating speed detection method of output speed data in real time.
The technical scheme that the present invention takes for the technical matters that exists in the solution known technology is:
Cutter suction dredger reamer rotating speed detection method of the present invention is gathered the motor rotary speed signal by the rotating signal harvester, and obtaining the rotating speed of reamer, tach signal pick-up and rotating signal harvester are in two respectively fully independently in the confined space; The rotating signal harvester is installed at tubular shaft port place at oil motor, rotating speed collector watertight guard shield is installed in the end caps of oil motor, make the working environment sealing of rotating signal harvester, tach signal pick-up support is installed on rotating speed collector watertight guard shield, by tach signal pick-up support fixed rotating speed signal pickup, by the reamer tachometer gage in lead connection tach signal pick-up and the pilothouse,, may further comprise the steps tach signal output:
A, oil motor rotate, and drive the rotating signal harvester rotation that is arranged on oil motor tubular shaft port place, and rotating signal harvester and tubular shaft rotate synchronously, and the rotating speed that the rotating signal harvester draws is the rotating speed of reamer;
B, tach signal pick-up pick up the speed of rotation parameter signal of rotating signal harvester;
C, tach signal pick-up are delivered to the V/I converter with reamer speed of rotation parameter and are carried out conversion of signals, send and the corresponding 4-20mA industry control of reamer rotating speed standard signal;
Current signal after D, V/I transducer will be changed drives pointer tachometer gage other forms of display terminal alive.
The present invention can also adopt following technical measures:
Described tach signal pick-up and rotating signal harvester relative position are fixed, and relative displacement does not take place in use for both.
Adopt soft being rigidly connected between the tubular shaft of described rotating signal harvester and oil motor.
Advantage and good effect that the present invention has are:
In the cutter suction dredger reamer rotating speed detection method of the present invention, tach signal pick-up and rotating signal harvester are in two respectively fully independently in the confined space, tach signal pick-up and rotating signal harvester relative position are fixed, and relative displacement does not take place in use for both.The rotating speed that the rotating signal harvester draws is the rotating speed of reamer, the tach signal pick-up picks up the speed of rotation parameter signal of rotating signal harvester, the tach signal pick-up is delivered to the V/I converter with reamer speed of rotation parameter and is carried out conversion of signals, send and the corresponding 4-20mA industry control of reamer rotating speed standard signal, the current signal after the V/I transducer will be changed drives pointer tachometer gage other forms of display terminal alive.Described detection method draws that the sensitivity of data is higher, antijamming capability is strong, watertightness is good, adapt under water working condition, installation and maintenance easy construction, output speed data electronic signal in real time.Have advantages such as practical, easy enforcement, accurate, the real-time output speed data of detection.
