Abstract

The utility model discloses a safety protector for a mine cable reducer. A temperature sensor and a liquid level transducer are arranged in the reducer; the temperature sensor and the liquid level transducer are connected with a safety protection circuit of the reducer; the safety protection circuit of the reducer comprises a PLC (programmable logic controller), a CAN/RS232 (controller area network/recommended standard 232) conversion module, an analog quantity input module and a switching power. The temperature sensor and the liquid level transducer are arranged in a gear box of the mine cable reducer, the running state of the reducer is judged by detecting the oil level height and temperature in the gear box; therefore, the faults of the reducer can be timely discovered; and personnel casualty damages caused by galloping of the mineral cable due to the damage of the gears of the gear box of the reducer can be avoided.

Description

Mining cableway reductor safety guard

Technical field

The utility model relates to a kind of mining cableway reductor safety device.

Background technology

Reductor on the mining cableway is the key equipment on the mining cableway, well whether its running state, the safe in operation that is related to mining cableway, because reductor fault, cause mining cableway driving, thereby the casualty accident that causes happens occasionally, causing reductor fault fault mainly is gear wear and damage in the reducer gear case, reason one is that gear case does not have oil or few oil, the gear dry grinding; The 2nd, oil quality difference or oil product are not right, can not form oil film on face of gear, and gear lubrication is insufficient; The 3rd, motor, coupler and gear disalignment.。

The utility model content

The purpose of this utility model provides a kind of height and oily temperature by lubricating oil in the detection reducer gear case and judges the reductor running state, thereby reaches the device to mining cableway reductor safety guard-safeguard.

The purpose of this utility model realizes in the following way: mining cableway reductor safety guard, at reductor temperature sensor and fluid level transmitter are being housed, temperature sensor and fluid level transmitter are connected to the reductor safety protective circuit, described reductor safety protective circuit comprises PLC, the CAN/RS232 modular converter, the analog quantity load module, Switching Power Supply, its annexation is: the N of PLC and Switching Power Supply, the L end connects AC127V input power supply respectively, the VCC1 of analog quantity load module meets the 5V of Switching Power Supply, VSS1 meets the GND2 of Switching Power Supply, 12V meets the 12V of Switching Power Supply, VSS meets the GND1 of Switching Power Supply, CANH, the CANH of CANL and CAN/RS232 modular converter, CANL joins; Input channel IN2 connects 1 pin of fluid level transmitter, and 2 pin of fluid level transmitter meet analog quantity load module input ground VSS; 1 pin of input channel IN4 jointing temp sensor, temperature sensor 2 pin meet analog quantity load module input ground VSS, 3 pin of temperature sensor meet the 12V of Switching Power Supply;

The VCC of CAN/RS232 modular converter meets the 5V of Switching Power Supply, and VSS meets the GND2 of Switching Power Supply, and signal sending end TXD, signal receiving end RXD are connected with signal ground GND with signal receiving end RXD, the signal sending end TXD of PLC respectively with signal ground GND.

The utility model is equipped with fluid level transmitter and temperature sensor in the gear case of mining cableway reductor, by fuel head and temperature in the detection of gear case, judge the running state of reductor, can in time find the reductor fault, avoid damaging, cause the generation of the personnel casualty accidents that mining cableway driving causes because of reducer gear case gear.

Description of drawings

Fig. 1 is a scheme of installation of the present utility model;

Fig. 2 is a circuit diagram of the present utility model;

The specific embodiment

As Fig. 1, shown in Figure 2, mining cableway reductor safety guard, motor 1 is connected on the reductor 2 by coupler, reductor 2 connects cableway drive wheel 3, on reductor 2, temperature sensor 4 and fluid level transmitter 5 are being housed, temperature sensor 4 and fluid level transmitter 5 are connected to the reductor safety protective circuit, described reductor safety protective circuit comprises PLC, the CAN/RS232 modular converter, the analog quantity load module, Switching Power Supply, its annexation is: the N of PLC and Switching Power Supply, the L end connects AC127V input power supply respectively, the VCC1 of analog quantity load module meets the 5V of Switching Power Supply, VSS1 meets the GND2 of Switching Power Supply, 12V meets the 12V of Switching Power Supply, VSS meets the GND1 of Switching Power Supply, CANH, the CANH of CANL and CAN/RS232 modular converter, CANL joins; Input channel IN2 connects 1 pin of

fluid level transmitter

5, and 2 pin of fluid level transmitter 5 meet analog quantity load module input ground VSS; 1 pin of input channel IN4 jointing temp sensor 4,42 pin of temperature sensor meet analog quantity load module input ground VSS, and 3 pin of temperature sensor 4 meet the 12V of Switching Power Supply;

Principle of work of the present utility model is: the CAN/RS232 modular converter will carry out treatment conversion with the bus signals that collects by CANH, CANL and become the RS232 signal, PLC is by signal receiving end RXD and ground end GND received signal, carry out signal processing analysis then, and the result sent to the CAN/RS232 modular converter once more by signal sending end TXD and signal ground GND, the CAN/RS232 modular converter converts the RS232 signal that receives the CAN signal to and sends to the analog quantity load module by the CAN bus.When the lubricating oil place value that the temperature value that detects the reductor after analog quantity conversion as PLC surpasses PLC programmed values or reductor is lower than the PLC programmed values, the electric-control system auto-stop, thus the control cableway is out of service.
