Abstract

The utility model discloses an automatic control bevel protractor, comprising a support seat, wherein a gravity oscillating bar overhanging downwards is hinged on the support seat; a reed switch is assembled at the overhanging end of the gravity oscillating bar; angle staffs are arranged behind the overhanging end of the gravity oscillating bar at an interval; two trigger magnets are fixedly arranged on the angle staffs, and are respectively positioned at the places corresponding to the extreme tilt angles at two sides of the preset sector oscillating range of the gravity oscillating bar; scales distributed at intervals along the oscillating curve direction of the gravity oscillating bar is arranged between the two trigger magnets on the angle staffs. A worker can judge the deviation degree of the tested equipment through a scale indicated by the overhanging end of the gravity oscillating bar on each angle staff when the automatic control bevel protractor is used, and the reed switch at the overhanging end of the gravity oscillating bar induces the trigger magnets to generate an induction trigger signal when the gravity oscillating bar swings to the positions at two ends of the preset swing stoke. Thus, the structure of the bevel protractor is simplified, and the use difficulty is reduced.

Embodiment

The embodiment of automatic control angle chi of the present utility model: as depicted in figs. 1 and 2, this automatic control angle chi is the automatic control angle chi of a kind of pendulum model, it comprises the bearing 2 and the angle scale 8 that are installed on equipment under test, on bearing 2, rotate the gravity fork 3 of assembling, wherein, the upper end of gravity fork 3 is connected on bearing 2, lower end overhangs downwards to the front side of angle scale 8, so that being connected with bearing 2, gravity fork 3 forms clock-type swing rod structure, and gravity fork 3 is hollow levers, in the projecting end of gravity fork 3, be equipped with dry reed switch 7, the signal lead that dry reed switch 7 up-samplings connect is located in gravity fork 3, and the pigtail splice 5 of the fairlead extending by the front and back of offering on bearing 2 and the assembling of fairlead front end passes, and be connected on the outer associated main frame arranging of bevel protractor with sampling.The two ends, left and right of angle scale 8 are fixed with respectively the triggering magnet 9 that makes to produce on dry reed switch 7 instantaneous punishment signal, between two punishment magnet, be provided with the scale 11 that indicates gravity fork 3 swing position, scale 11 has the final position at the zero-bit of the projecting end oscillating stroke middle position in gravity fork 3 and the projecting end oscillating stroke end positions place in gravity fork 3, and two final positions are worth all and reduce gradually to the scale 11 of zero-bit.

On bearing 2, in the front side of gravity fork 3, be equipped with circlip for shaft 4.Pigtail splice 5 is water joints of stainless steel, and in pigtail splice 5, offers the joint endoporus passing for signal lead.At the waterproof end plug 1 of the rear end of the fairlead of bearing 2 assembling.Position on gravity fork 3 between bearing 2 and angle scale 8 is fixed with balancing weight 6.On angle scale 8, be also installed with the guide plate in scale 11 belows, guide plate is the arc bent plate extending along the projecting end oscillating stroke arc direction of gravity fork 3, on guide plate, offer with the projecting end of gravity fork 3 along the oscillating stroke arc direction long guiding hole coordinating that leads, the projecting end of gravity fork 3 is located in this long guiding hole.At the two ends of guide plate, be respectively equipped with 10, two limiting plates 10 of limiting plate of being connected on angle scale 8 all and the projecting end block of gravity fork 3 coordinates and stop the projecting end of gravity fork 3 to be rocked to outside two oscillating strokes that trigger between magnet 9.

Bearing 2 and angle scale 8 are arranged on the side of equipment under test; when equipment under test tilts; gravity fork 3 starts to swing; along with the increase of pendulum angle; the projecting end of gravity fork 3 progressively will wave before angle scale 8; encounter after limiting plate 10; stop waving; simultaneously; gravity fork 3 touches gradually and triggers the magnetic regions of magnet 9, and dry reed switch 7 senses feedback signal after the magnetic that triggers magnet 9, then by signal lead, feeds back to associated main frame; associated main frame sends power-off signal, thereby equipment under test is well protected.Therefore the present embodiment swings fork by the Action of Gravity Field of balancing weight 6, and the scale 11 of indicating on angle scale 8 by gravity fork 3 is worth reading out data.By magnetic induction principle, when being rocked to after predetermined angular, magnetic strength signal sets out and feeds back to associated main frame, and main frame sends control signal, by electric equipment power-off, thereby has protected electric equipment not to be subject to the damage causing because of the excessive problem in angle of inclination.
