Each photoelectric switch and collector-block and described annunciator one_to_one corresponding, and be fixed on corresponding described collector-block, photoelectric switch and power supply and the annunciator corresponded form alarm loop; Photoelectric switch moves with the collector-block corresponded, and is closing apart from corresponding trolley setpoint distance place with the corresponding alarm loop of conducting.
Preferably, above-mentioned three annunciators are warning indicator lamp, and the color of three indicator lamps is different.
Preferably, above-mentioned three annunciators, are respectively the emergency alarm bell of three different the tinkle of bells.
Preferably, in foregoing circuit, add power control circuit, for controlling the output voltage of power supply.
Preferably, above-mentioned power control circuit controls electric power output voltage is 36V.
Preferably, photoelectric switch is fixed on described collector-block by flexible connecting member.
Preferably, above-mentioned flexible connecting member elects latex circle as.
The collector-block provided based on the utility model changes prior-warning device, the utility model also provides a kind of crane in bridge type, the crane in bridge type provided comprises collector-block and changes prior-warning device, wherein, described collector-block changes prior-warning device for the collector-block replacing prior-warning device described in above-mentioned any one.
It is as follows that the collector-block that the utility model provides changes prior-warning device working process: each photoelectric switch is fixed on corresponding collector-block, when collector-block may wear to corresponding trolley setpoint distance, photoelectric switch corresponding on collector-block closes, communication apparatus circuit, alarm equipment alarm, collector-block is changed in display.Moment is detected collector-block wear pattern; avoid affecting equipment availability because of not changing collector-block in time; cause unnecessary economic loss; avoid the maintenance frame by service personnel access arrangement simultaneously; the detection carrying out collector-block wear condition judges then to determine that collector-block is changed; protection to service personnel life safety when improve repair apparatus, improves the work efficiency changing collector-block.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, for those of ordinary skills, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Detailed description of the invention
The utility model embodiment provides a kind of collector-block to change prior-warning device, can realize to collector-block Real-Time Monitoring, when reaching the replacing condition of setting, automatic alarm, collector-block is changed in prompting, judge that collector-block is the need of replacing, increases work efficiency safely and fast accurately, solve background technology and rely on manpower to carry out the problem of collector-block wear pattern judgement.
Technical scheme in the utility model embodiment is understood better in order to make those skilled in the art person, and enable the above-mentioned purpose of the utility model embodiment, feature and advantage become apparent more, below in conjunction with accompanying drawing, the technical scheme in the utility model embodiment is described in further detail.
Please refer to accompanying drawing 1, the collector-block that the figure shows the utility model embodiment provides changes the structure of prior-warning device.The collector-block that the utility model example provides is changed prior-warning device and is comprised, three photoelectric switchs 2, three annunciators 7, power supply 6, each photoelectric switch 2 is separately fixed on each collector-block 3, each photoelectric switch 2 and annunciator 7 one_to_one corresponding, and form three alarm loops with power supply 6.Photoelectric switch 2 is along with collector-block 3 one pieces of movements, in whole moving process, collector-block 3 weares and teares, prefastening force spring extruding collector-block 3 on current colector support 4 moves, and the distance between the trolley 1 at corresponding photoelectric switch 2 and collector-block 3 place constantly reduces, when reaching the distance of setting, this photoelectric switch 2 closes, make the alarm loop conducting at its place, the corresponding annunciator 7 in loop is reported to the police, and reminds staff to change collector-block 3.Such scheme more convenient prompting staff can change collector-block 3, and does not need staff to go inspection to judge that collector-block 3 is the need of replacing, increases work efficiency, and ensures the personal safety of staff simultaneously.
It is preferred that the collector-block that the utility model example provides changes prior-warning device, three annunciators 7 can be three warning indicator lamps, warning indicator lamp is in luminance when reporting to the police, and now operating personal can determine the alarm loop being in alarm condition more intuitively.But, in some cases because equipment line is intricate, the alarm loop that operating personal determination warning indicator lamp is corresponding is easier to make a mistake, in the utility model embodiment, three annunciators 7 can be the warning indicator lamp of three different glow colors for this reason, each Color pair should specific alarm loop, so that operating personal determines the alarm loop being in alarm condition quickly.Certainly, when annunciator 7 is warning indicator lamp, if when residing Premises Equipment is more or warning indicator lamp mounting condition limits to, the light of warning indicator lamp is easily obstructed, and this causes warning effect not good.For this reason, three annunciators 7 that the utility model embodiment provides can be also emergency alarm bell, and the impact that other equipment are received in bell sonic propagation is less, has good warning effect.Certainly, if the tinkle of bells of emergency alarm bell is the same, the problem determining alarm loop difficulty can be there is equally.Therefore more preferred, annunciator 7 can for integrating the panalarm of indicator lamp and the tinkle of bells.In such cases, not only intuitively can determine alarm loop, can also can receive alarm in region far away by operating personal when indicator lamp light path is obstructed simultaneously, and then improve warning efficiency.Certainly, above-mentioned three annunciators 7 also can be the emergency alarm bell of three different the tinkle of bells, and operating personal according to the tinkle of bells kind determination alarm loop, can play good warning effect equally.
The collector-block that the utility model example provides changes prior-warning device, and in order to safety, power saving, can also comprise the power control circuit be connected with power supply 6, power control circuit is for controlling the output voltage of power supply 6.In order to safe ready uses, the output voltage of power supply 6 can be set to 36V.
The collector-block that the utility model example provides changes prior-warning device, in equipment use process, collector-block 3 is ceaselessly moving around, but there is vibration in moving process, in order to reduce the impact of vibration on photoelectricity switch 2, photoelectricity switch 2 and collector-block 3 are fixedly linked preferably by flexible connecting member.Preferably, flexible connecting member can select latex circle 5.
The collector-block provided based on above-mentioned example changes prior-warning device, and the utility model additionally provides a kind of crane in bridge type, and the collector-block that this crane in bridge type comprises above-mentioned example to be provided changes prior-warning device.
Each embodiment in this specification sheets all adopts the mode of going forward one by one to describe, between each embodiment identical similar part mutually see, what each embodiment stressed is the difference with other embodiment.
Above-described the utility model embodiment, does not form the restriction to the utility model protection domain.Any do within spirit of the present utility model and principle amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
