Description
Technical field
The utility model belongs to shipbuilding industry, relates in particular to a kind of pitch ultramagnifier.
Background technology
But roll adjustment side direction propelling unit generally is made up of five big parts such as propulsion component, electric motor starting cabinet, hydraulic efficiency pressure system, electric-control system and feedback system or system.The pitch ultramagnifier is the important component part of feedback system, generally be fixed near the suitable position of hull of propelling unit, and in the thruster cabin, drive the control chamber be provided with instrument and meter, the control personnel driven by boats and ships or the maintainer is used for monitoring in real time propeller thrust direction and pitch size, helping driving the control personnel and handle thruster, is the strong safety control of motor and hydraulic efficiency pressure system simultaneously.
Various ultramagnifiers are all similar, all include sensor module, indicator collet, Transmission, connecting element and spring etc. basically, form a continuous system that back and forth moves back and forth.The technological deficiency that existing pitch ultramagnifier exists: complex structure, take up room big, reliability is relatively poor.
Summary of the invention
For the complex structure that overcomes existing pitch ultramagnifier, take up room big, the relatively poor deficiency of reliability, the utility model provides a kind of simple in structure, minimizing takes up room, reliability is good pitch ultramagnifier.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of pitch ultramagnifier, comprise sleeve pipe, case in and magnetic displacement transducer, described cased lower end is provided with the through hole that the pilot bar for side thruster stretches into, captive joint with the lower end of last sleeve pipe in described cased upper end, captive joint with pipe link in the upper end of described pilot bar, the upper end of described pipe link is provided with spring mounting seat, spring housing is contained on the described pipe link, the upper end of described spring withstands on the lower end of described spring mounting seat, the lower end of described spring withstands on described cased intracavity bottom, described spring mounting seat is sleeved on the inwall of sleeve pipe slidably, described magnetic displacement transducer comprises magnet and in order to the slide bar of induced magnet position, described magnet is captiveed joint with described spring mounting seat, the top of described magnet and pipe link all has cavity, and the top of described magnet and pipe link is sleeved on the described slide bar slidably.
Further, described magnet top fixed installation indicator collet, the last sleeve pipe in the described indicator collet outside is provided with dial window.
The beneficial effects of the utility model mainly show: simple in structure, minimizing takes up room, reliability is good.
Description of drawings
Fig. 1 is the structural representation of pitch ultramagnifier.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1, a kind of pitch ultramagnifier, comprise sleeve pipe 1, case in 2 and magnetic displacement transducer, the lower end of described case in 2 is provided with the through hole that the pilot bar 3 for side thruster stretches into, captive joint with the lower end of last sleeve pipe 1 in the upper end of described case in 2, captive joint with pipe link 4 in the upper end of described pilot bar 3, the upper end of described pipe link 4 is provided with spring mounting seat, spring 5 is sleeved on the described pipe link, the upper end of described spring 5 withstands on the lower end of described spring mounting seat, the lower end of described spring 5 withstands on the intracavity bottom of described case in 2, described spring mounting seat is sleeved on the inwall of sleeve pipe 1 slidably, described magnetic displacement transducer comprises magnet 6 and in order to the slide bar of induced magnet position, described magnet 6 is captiveed joint with described spring mounting seat, the top of described magnet 6 and pipe link 4 all has cavity, and the top of described magnet 6 and pipe link is sleeved on the described slide bar slidably.
Described magnet 6 tops fixed installation indicator collet 7, the last sleeve pipe in described indicator collet 7 outsides is provided with dial window.
Described magnetic displacement transducer can pass the signal along to drives the control cabin, and navigating mate can read pitch information in real time in driving the control cabin; When maintenance, the maintenance worker can read current pitch information by dial window.
In the present embodiment, the pitch ultramagnifier adopts magnetic displacement transducer and the combined formula of compression spring.By the adjusting of hydraulic pressure unit, when screw propeller became completely (positive car) pitch by zero pitch, indicator collet was down moved by zero graduation, reached till the following full scale; When being transferred to full (reversing) pitch by full (positive car) pitch, because the effect of spring, indicator collet is up moved by full scale down again, and reaching expires till (scale).
This device has following several big advantage: simple in structure under the prerequisite that satisfies the pitch feedback request.Whole device only by sensor (containing magnetic patch), indicator collet, spring, pipe link, go up sleeve pipe, case in, bolt etc. totally eight kinds of parts form, easy for installation;
It is little to take up room.Whole device may be limited in the altitude range of 370mm, and this height is less than 473mm distance between cylinder and the motor, and promptly this device need not to take in addition other spaces in the thruster cabin, only need be installed on the cylinder of thruster to get final product.
Cost of serving is low, and this device can need not to instruct docker again or send someone the shipyard on-site installation with thruster together in the shop assembly debugging.Applied widely, the magnetic displacement transducer that is adopted in this device can be used for harsies environment such as vibration, low temperature, noise, so this device can satisfy most kind boats and ships such as towboat, auxiliary vessel, oil carrier, Scientific Research Ship fully.
