Description
Technical field
The utility model belongs to shipbuilding industry, particularly 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, and help driving the control personnel and handle thruster, be 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: occupy that the space is big, Applicable scope is little, cost of serving is high.
Summary of the invention
In order to overcome the deficiency big, that Applicable scope is little, cost of serving is high that takes up room of existing pitch ultramagnifier, the utility model provides a kind of pitch ultramagnifier that takes up room little, applied widely.
The technical scheme that the utility model adopts is:
A kind of pitch ultramagnifier; Comprise sleeve pipe, case in and magnetic displacement transducer, it is characterized in that said magnetic displacement transducer comprises magnet and in order to the slide bar of induced magnet position; Said sensor is connected through screw retention with the upper end of last sleeve pipe; Said lower end of going up sleeve pipe is threaded with said cased upper end, and said cased lower end is threaded with the pilot bar of side thruster, and the upper end of said pilot bar is threaded with the lower end of pipe link; Spring is pressed into the lower end of said pipe link, and said spring lower end withstands on said cased intracavity bottom; The top of said magnet and said pipe link all has cavity, and the top of said magnet and pipe link slidably is sleeved on the said slide bar.
Further, indicator collet is installed through bolt in said magnet top, and the last sleeve pipe in the said indicator collet outside is provided with dial window.
The beneficial effect of the utility model is embodied in: take up room little, cost of serving is low, applied widely.
Description of drawings
Fig. 1 is the utility model pitch ultramagnifier structural representation.
The specific embodiment
With reference to Fig. 1; A kind of pitch ultramagnifier comprises sleeve pipe 1, case in 2 and magnetic displacement transducer 3, and characteristics are that said magnetic displacement transducer 3 comprises magnet 7 and in order to the slide bar of induced magnet position; Said sensor 3 is captiveed joint through screw 10 with the upper end of last sleeve pipe 1; Said lower end of going up sleeve pipe 1 is threaded with the upper end of said case in 2, and the lower end of said case in 2 is threaded with the pilot bar of side thruster 4, and the upper end of said pilot bar 4 is threaded with the lower end of pipe link 6; Spring 5 is pressed into the lower end of said pipe link 6, and said spring 5 lower ends withstand on the intracavity bottom of said case in 2; The top of said magnet 7 and said pipe link 6 all has cavity, and the top of said magnet 7 and pipe link 6 slidably is sleeved on the said slide bar.
Further, said magnet 7 tops are through bolt 9 fixed installation indicator collets 8, and the last sleeve pipe 1 in said indicator collet 8 outsides is provided with dial window.
The utility model pitch ultramagnifier adopts magnetic displacement transducer and the combined formula of compression spring.Through 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 under the prerequisite that satisfies the pitch feedback request:
Simple in structure: 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.And in the pitch ultramagnifier in the past (seeing figure three), parts are more, need tens kinds of parts.
Easy for installation:
1, pipe box is installed down: get final product through screwed with the side thruster device.
2, spring is placed: spring is put in the case in got final product.
3, pipe link is installed: be pressed into spring until the lower end of pipe link and the pilot bar touching of side thruster, peaceful tight screw thread gets final product.
4, indicator collet is fixed: put into magnetic patch and indicator collet, tighten with bolt.
5, sensor and last sleeve pipe are fixed, and whole afterwards and case in install through being threaded.
It is little to take up room: whole device may be limited in the altitude range of 370mm, and this height is less than 473 distances between cylinder and the motor, and promptly this device need not in the thruster cabin, to take in addition other spaces, only need be installed on the cylinder of thruster to get final product.
Cost of serving is low: 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.
The described content of this specification sheets embodiment only is enumerating the way of realization of utility model design; Should not being regarded as of the protection domain of the utility model only limits to the concrete form that embodiment states, the protection domain of the utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
