Abstract
The utility model discloses an angle limit alarm sensor device. The angle limit alarm sensor device comprises a support which is hinged to a gravity pendulum rod which overhangs downward; a trigger magnet is fixedly arranged on the overhanging portion of the gravity pendulum rod; two magnetic induction elements are assembled on the pendulum track of the trigger magnet; the two magnetic induction elements are located at the positions corresponding to limit pendulum angles of the bilateral sides of the preset fan-shaped pendulum range of the gravity pendulum rod respectively; the two magnetic induction elements are electrically connected onto an alarm. The solid pendulum type structure is adopted and the principle of electromagnetic induction is utilized. The trigger magnet moves in a pendulum mode along with the gravity pendulum rod, induction signals are produced on the magnetic induction elements when the trigger magnet reaches the corresponding positions in front of the magnetic induction elements, and accordingly an alarm is given through the alarm when the degree of deviation of a detected device reaches the limit. Accordingly, the angle limit alarm sensor device has the advantages of being simple in structure and convenient to use.
Description
Technical field
The utility model relates to a kind of angle spacing alarm sensor device.
Background technology
At present, under coal mine due to lack reference and light a little less than, the leveling of equipment is difficulty quite, particularly for angle of inclination, require stricter equipment, as gear-box, booster pump etc., gradient General Requirements is one-sided is no more than 5 °, and the how accurate leveling of so little scope becomes difficult point.Angle alarm sensor is a lot of on the market, operating principle, can be divided into " solid pendulum " formula, " liquid pendulum " formula, " gas pendulum " three kinds, in each field, all obtained good effect, but for meeting down-hole, do the used time and report to the police and again equipment is carried out the requirement of low-angle control in the environment of explosion hazard, the complex structure of existing alarm sensor, use inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of angle spacing alarm sensor device simple in structure, easy to use.
In order to realize above object, the technical scheme of angle spacing alarm sensor device of the present utility model is as follows:
A kind of angle spacing alarm sensor device, comprise for being fixed on the bearing on equipment under test, on bearing, be hinged with the gravity fork overhanging downwards, the overhang of gravity fork is installed with triggering magnet, and be equipped with for being installed in equipment under test on the swinging track that triggers magnet, to produce two magnetic induction parts of induction triggering signal when triggering magnet through corresponding position, the place ahead, two magnetic induction parts are the limit pivot angle corresponding position of the default fan-shaped hunting range both sides in gravity fork respectively, and two magnetic induction parts are all connected electrically on alarm.
The projecting end of described gravity fork is fixed with weight, and described triggering magnet is installed on weight.
Described weight is the discoid hammer body in gravity fork lower end position place.
Two described magnetic induction parts are fixed on sense base, the below of described sense base in bearing, and sense base is along the arc base that triggers the square extension of swinging track of magnet.
Also comprise when being rocked to limit pivot angle corresponding position at gravity fork block gravity fork to swing and keep the stopping means of present position.
Described stopping means is for being installed in the backing pin on equipment under test, the middle part corresponding position of described backing pin in gravity fork.
The utility model is installed with bearing on equipment under test, on bearing, be hinged with the gravity fork overhanging downwards, on the projecting end of gravity fork, be equipped with triggering magnet, and on equipment under test, be also installed with two magnetic induction parts on the swinging track in triggering magnet, two magnetic induction parts are arranged in the limit pivot angle corresponding position of the default fan-shaped hunting range both sides of gravity fork, sensor device therefore of the present utility model adopts " solid pendulum " formula structure, the design of application electromagnetic induction principle.Triggering magnet is swinging with gravity fork, when arriving corresponding position, magnetic induction part the place ahead, on magnetic induction part, produce induced signal, so that the deflection of equipment under test reaches capacity, alarm device is reported to the police, and therefore sensor of the present utility model has advantages of simple in structure, easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
The embodiment of angle spacing alarm sensor device of the present utility model: as depicted in figs. 1 and 2, this angle spacing alarm sensor device is a kind of pendulum model angle spacing alarm sensor device, it comprises the gravity fork 3 that rotates assembling on the bearing 4 that is installed on equipment under test and sense base 1, bearing 4, wherein, the upper end of gravity fork 3 is connected to bearing 4 upper and lower ends and overhangs downwards to the front side of sense base 1, the projecting end of gravity fork 3 is fixed with discoid weight 5, forms clock-type swing rod structure so that weight 5, gravity fork 3 and bearing 4 are connected.In the rear end of weight 5, inlay to be fixed with and trigger magnet 7.The two ends, left and right of sense base 1 are fixed with respectively induction when triggering magnet 7 in dead ahead and produce the magnetic induction part 6 of responding to triggering signal, two magnetic induction part 6 samplings are connected on the outer main control system arranging of sensor, are equipped with the alarm being connected respectively with two magnetic induction parts 6 simultaneously on sense base 1.
In the left and right sides of gravity fork 3, be respectively equipped with the stopping means 2 being connected on equipment under test, two stopping means 2 are block gravity fork when triggering magnet is rocked to limit pivot angle corresponding position and swing and the backing pin of maintenance present position, the middle part corresponding position of backing pin in gravity fork.
When equipment under test tilts, gravity fork 3 is because the Action of Gravity Field of weight 5 swings left or to the right, when weight 5 swings to the dead ahead of magnetic induction part 6, on magnetic induction part 6, produce instantaneous induced signal, the circuit of alarm is connected, and alarm lamp is bright, and sends chimes of doom; Meanwhile, the voltage signal of magnetic induction part 6 output 5V is to the control panel on main control system.Because magnetic induction part 6 exists induction range, so increased by two stopping means.When the triggering magnet on gravity fork is rocked to limit pivot angle corresponding position, gravity fork no longer swings under the block effect of stopping means beyond fan-shaped wobble area, so that trigger the magnet corresponding position in magnetic induction part the place ahead all the time, guarantee that, when angle of inclination exceeds, sound and light alarm and control signal continue.Therefore sensor application pendulum of the present utility model and electromagnetic induction principle, realize low-angle accurate measurement, realizes the automatic control to equipment start-stop in the time of spacing alarm.Adopt contactless structure, avoid potential safety hazard.Indices meets the requirement of equipment mining intrinsic safety type for national explosive gas atmosphere, and energy reliability application is in national explosive gas atmospheres such as collieries.
In the above-described embodiments, trigger magnet and inlay in the rear end that is installed in weight, in other embodiments, trigger that magnet also can be bolted, welding, other modes such as bonding be fixed on other positions of weight.
