Abstract
The utility model discloses a warning device for a broken chain of a buried scraper machine so as to solve the problem that whether a transportation device is broken or not due to breakdowns cannot be observed currently. An induction piece is arranged on a driven shaft. A proximity sensor is arranged on one side of the driven shaft and is connected with a controller. The controller is connected with an alarm through a timer. According to the warning device for the broken chain of the buried scraper machine, the proximity sensor collects analog quantity signals in the rotation process and carries out analog-digital conversion, therefore, an alarm is given through output of digital signals, and the proximity sensor is ingeniously applied to the broken chain protection. The warning device is simple and practical, a control circuit is simple, control equipment is simple in structure, the warning device is strong in interactivity and further can be connected with a PLC directly, and complex alarm control can be achieved.
Description
Technical field
The utility model relates to a kind of chain rupture warning device, is specifically related to a kind of scraper plate machine chain rupture warning device that buries.
Background technology
Bury the scraper plate machine and use comparatively generally in the pyrometallurgy industry, its type of drive is that the rotation by imput shaft drives the transportation device that is installed in the confined space, but because whether sealing can't observe transportation device because fault disconnects.
The utility model content
The purpose of this utility model is for a kind of scraper plate machine chain rupture warning device that buries being provided, can't observing the problem whether transportation device disconnects because of fault to solve at present.
Technical solutions of the utility model are as follows: a kind of scraper plate machine chain rupture warning device that buries, be provided with sensing chip at driven shaft, be provided with the proximity sensor in described driven shaft one side, described proximity sensor links to each other with controller, and described controller links to each other with annunciator by timer.
The relative prior art of the utility model has following beneficial effect: the utility model is installed the chain rupture warning device at driven shaft, when transportation device disconnects, driven shaft can not rotate, the chain rupture warning device is gathered the analog signals of rotary course by the proximity sensor, and carry out analogue to digital conversion, thereby judge whether to take place chain rupture and report to the police by the running state that the output digital quantity signal detects driven shaft.It is simple and practical, has stronger interactively, can also directly link to each other with PLC, realizes the alarm control of more complicated.
Description of drawings
Fig. 1 is a kind of structural representation that buries scraper plate machine chain rupture warning device;
Fig. 2 is a kind of control scheme drawing that buries scraper plate machine chain rupture warning device.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment:
A kind of scraper plate machine chain rupture warning device that buries is provided with sensing chip 2 at driven shaft 6, is provided with proximity sensor 1 in driven shaft 6 one sides, and proximity sensor 1 links to each other with controller 3, and controller 3 links to each other with annunciator 5 by timer 4.Controller 3 is intermediate relay or Programmable Logic Controller.
During work, sensing chip 2 whenever rotates a circle along with driven shaft 6 rotations, and proximity sensor 1 moves once, thereby has realized collection and the conversion of analog signals, after converting, the digital quantity signal that collects is sent into controller carry out computing.Typical operational method is, use the normal normally closed point 8 of the 7 and second auxiliary output of making war of the first auxiliary output of controller 3 respectively as the start timing signal of first timer 41 and second timer 42, the first auxiliary normally closed point 9 of output and the second auxiliary output of use controller 3 often make war 10 respectively as the reset signal of first timer 41 and second timer 42, and the time of timer can be set according to on-the-spot actual needs.When the generation chain rupture is that can only there be two kinds of situations in proximity sensor 1, connects or disconnects after driven shaft 6 stopped action, when proximity sensor 1 is connected, during the first auxiliary output normal battles 7 of connection, normally closed point 9 disconnects, and first timer 41 beginnings regularly, before timing arrives, if proximity sensor 1 state does not change, think namely chain rupture taken place that first timer 41 arrives the back action at timing, the closure normal battles 11 of timer 41, siren horn 5 are sent chain rupture and are reported to the police; When proximity sensor 1 disconnects, when the normally closed point 8 of the second auxiliary output is connected, normal 10 disconnections of making war of the second auxiliary output, second timer 42 beginning timings are before timing arrives, if proximity sensor 1 state does not change, namely think chain rupture has taken place, first timer 42 arrives the back action at timing, the closure normal battles 12 of timer 42, and siren horn 5 sends chain rupture and reports to the police.When chain rupture does not take place when, 6 every 1 weeks of rotation of driven shaft, proximity sensor 1 action once, normally closed point 9 and the second auxiliary output is normal makes war 10 state variation once, first timer 41 and second timer are carried out reset operation, the misoperation of avoiding reclocking and causing one time; Simultaneously, after the chain rupture fault was got rid of, driven shaft rotated for 1 week, can reset to warning.
The warning device of chain rupture simultaneously can also be chain with running state, and the running state that is about to imput shaft 6 also seals in the alarm, arrives when 4 times of timer, but do not have running state, can think that this equipment is artificial out of service, and do not give the alarm this moment.
