Abstract
The utility model discloses a mining auxiliary winch backup protection equipment, the utility model discloses a PLC controller, winch the control unit, position sensor, speedtransmitter, read card unit and alarm unit, winch the control unit, position sensor, speedtransmitter, read the card unit and the PLC controller is all connected to the alarm unit, and position sensor is used for detecting the winch position, and speedtransmitter is used for detecting winch functioning speed. The utility model discloses not only avoid the emergence of above accident in the application in colliery, also made transportation safety obtain further assurance and improvement, made positive contribution for coal mine safety production.
Description
Technical field
The utility model relates to a kind of mining electric apparatus, particularly a kind of mining auxiliary hoist back-up protection equipment.
Background technology
In recent years, all kinds of auxiliary hoist of underground coal mine (hereinafter referred to as puffer) accident remains high, safety misadventure occurs repeatedly, from analysis accident conditions, major part accident is not mainly because puffer has the degree of depth and speed display in operational process, make hoistman can not grasp winch running condition at any time, thus cause the accident such as pulleying, overspeed, some accident is then be not easy to management because puffer uses, user of service is chaotic, miner not through training operates against regulations in violation of rules and regulations, and this is also the major reason caused the accident.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of mining auxiliary hoist back-up protection equipment improving mining auxiliary hoist safety in operation.
In order to solve the problems of the technologies described above, the utility model comprises PLC, winch control unit, position transduser, speed sensor, card reading unit and alarm unit, winch control unit, position transduser, speed sensor, card reading unit are all connected PLC with alarm unit, position transduser is for detecting winch position, and speed sensor is for detecting winch running velocity.
For the ease of monitoring, also include upper computer, PLC connects upper computer.
In order to obtain better warning effect, described alarm unit comprises audio alert unit and light alarm unit.
Described light alarm unit includes the alarm lamp of four kinds of colors.
In order to improve safety, described position transduser is connected PLC with speed sensor by isolation safe grid, and described alarm unit connects PLC by isolation safe circuit.
For improving the accuracy controlled winch, the accuracy of detection of described position transduser is 0.1m; The accuracy of detection of described speed sensor is 0.1m/s.
The beneficial effects of the utility model are: the utility model achieves the accurate detection and control to running the degree of depth (i.e. winch position) and speed, makes driver very clear to winch operational process, facilitates the operation to auxiliary hoist and control; Also research achieves puffer and " authorizes and open " function, the dedicated driver only holding authorization card could operate winch, this device not only avoid the generation of above accident in the application in colliery, also make transportation safety obtain to ensure further and improve, for Safety of Coal Mine Production makes positive contribution.
Accompanying drawing explanation
Fig. 1 is control principle drawing of the present utility model.
Detailed description of the invention
Specific embodiment as shown in Figure 1, it comprises PLC, winch control unit, position transduser, speed sensor, card reading unit, upper computer, audio alert unit and light alarm unit, winch control unit, position transduser, speed sensor, card reading unit are all connected PLC with alarm unit, PLC connects upper computer, position transduser is for detecting winch position, and speed sensor is for detecting winch running velocity.Light alarm unit includes the alarm lamp of four kinds of colors, can be red, yellow, blue, green four kinds of colors.Position transduser is connected PLC with speed sensor by isolation safe grid, and described alarm unit connects PLC by isolation safe circuit.
Principle of work: detection signal is passed to PLC by position transduser and speed sensor, PLC exports corresponding control signal according to the position of winch and speed conditions to winch control unit and annunciator.
Radical function:
(1) overtravel protection function
A) upper overtravel protection: when winch is up reach the upper limit position of setting time, audio alert unit sends corresponding voice message and amber light is bright, and PLC exports speed-slackening signal to winch control unit and makes winch out of service simultaneously.
B) overtravel protection under: when winch is descending reach the lower position of setting time, audio alert unit sends corresponding voice message and Lan Dengliang, and simultaneously PLC exports speed-slackening signal to winch control unit and makes winch out of service.
(2) speed protection function
Negotiation speed sensor detects speed when winch runs; when winch speed exceedes 15% of setting value; audio alert unit sends corresponding voice message and when red, and PLC sends speed protection control signal to winch control unit, adjustment winch speed.
When the speed of winch and position are all in normal condition, green light, audio alert unit not sounding.
(3), open function is authorized
The winch manipulation personnel only possessing operation license (holding job card) just can operate.When main frame does not insert job card, winch control unit automatically locks, and points out " user right ", please insert job card.
(3-1) job card
Job card is held by full-time hoistman, has the identity information of driver in card, card reading unit readable information, when job card presses close to card reading unit, namely PLC can read the information identifying job card, by comparing with the information of setting, confirms that whether this card is effective.Whether holder for confirmation has the right operates winch.
(3-2) control card
Control card is held by chief leading cadre and safety supervision person.The principal data such as time, speed that winch runs can be made a copy of and be inquired about and supervision and management by upper computer.
