Abstract
The utility model discloses a system for supervising haulage winch tension, which comprises a KZQ-1 controller. An input foot 1-1 of the KZQ-1 controller is connected with a pressure sensor; an output foot 1-1 of the KZQ-1 controller is connected with a warning light; an output foot 1-2 of the KZQ-1 controller is connected with a warning horn; a BPQ-1 frequency converter is connected among a foot 9 of the KZQ-1 controller, a foot 10 of the KZQ-1 controller, a tail margin of the KZQ-1 controller and a driving motor; a relay is connected between an output foot 1-3 and a main circuit of the haulage winch motor. A real time supervision of the rope tension during overloading and a real time display can be realized. When the tension caused by loading or other elements exceeds a safe value, an acousto-optic alarming is realized and protection is implemented, breakdowns such as cable breaking and hook releasing are prevented, thereby effectively prolonging the service life of wire ropes, reducing breakdowns and improving running safety of the haulage winch. Furthermore, supervision of the tension is realized by use of a single chip machine, and the haulage winch is enabled to be safe in running, convenient to maintain, and suitable for the supervision of the tension of the haulage winch in a mine.
Description
Technical field
The utility model relates to a kind of haulage gear tension monitoring device of colliery.
Background technology
Winch is mainly transportation lane, exploiting field and promotes the material use in mine is produced.On the one hand the winch overload easily shortens wirerope service life; On the other hand because down-hole geologic condition complexity, winch speed is when drawing over to one's side speed, and surplus rope too much causes winch and goes too far before the capstan drum, is prone to casualty accident.At present, coal enterprise is for preventing disconnected cable derailing accident, adopts hypervelocity stops, A type, C type stop buffer etc. more, but still fails the effectively generation of the disconnected cable derailing accident of control; The overload phenomenon there is not effective monitoring device yet.
Summary of the invention
In order to overcome effective defective that disconnected cable derailing accident takes place of controlling of failing of known hypervelocity stop, stop buffer, the utility model provides a kind of haulage gear tension monitoring system, this system can monitor effectively to the overload phenomenon, the generation of the disconnected cable derailing accident of control.
The technical solution of the utility model is: this system comprises that this winch safety system comprises the KZQ-1 type controller, and the input 1-1 pin of KZQ-1 type controller is connected to pressure sensor, the alarm lamp that the output 1-1 pin of KZQ-1 type controller is connected to; The output 1-2 pin of KZQ-1 type controller is connected to alarming horn; Be connected to BPQ-1 type BPQ-1 type frequency converter between 9 pin of KZQ-1 type controller, 10 pin, lower margin and the drive motor, be connected to relay between the output 1-3 pin of KZQ-1 type controller and the winch motor power circuit.
Advantage of the present utility model: can monitor the variation of cable tension to overloading in real time, and show in real time.When load-carrying or other factors cause tension force to surpass safety value, sound and light alarm, and implement protection, and prevent the generation of faults such as disconnected cable, unhook, effectively prolong the wirerope life-span, reducing fault takes place, and improves the winch safety in operation.Adopt Single Chip Microcomputer (SCM) system to realize the monitoring of tension force, control system is perfect, safe in operation, easy to maintenance.
