Abstract
The utility model relates to a mine hoisting container protection device, wherein an encoder is arranged on a head sheave, a current transducer is arranged on a motor, a limit switch is arranged on a tank channel, and a PLC is arranged in a hoisting computer room. Signals of the encoder, the current transducer and the limit switch are sent into the PLC, and are analyzed and judged in the inner portion of the PLC, the signals are sent to fault alarming and interlocking after being analyzed and judged in the inner portion of the PLC, and the fault alarming and the interlocking output signals to a hoist main electric control system. The mine hoisting container protection device can meet the control demands of a mine for the hoisting system, and the system has high control precision and is safe and reliable. The mine hoisting container protection device can achieve the automation and the intelligent of the mine hoisting system, can alarm and lock in time after analysing and comparing according to the position of a hoisting container and the operation state of a hoist, and can guarantee the safety of mine hoisting personnel and hoisting equipment.
Description
Technical field
The utility model relates to a kind of mine electronic product, especially a kind of mine hoisting container fender guard.
Background technology
At present, mine hoisting system does not also have perfect lifting container on-line intelligence surveillance monitor device, repeatedly takes place because lifting container is blocked and accident of cage crashing in cage guide, and the lighter causes substantial equipment to damage, can cause great personnel casualty accidents when serious, have a strong impact on mine safety.Therefore, be badly in need of a kind of mine hoisting container on-line intelligence surveillance monitor device of exploitation, can realize the automation and the intelligent surveillance monitor of mine hoisting container for mine safety; Can judge according to the relative position of the running state of gig and lifting container in good time and have or not card jar trend and phenomenon and can in time report to the police or stop.
The utility model content
The utility model is monitored ineffective lifting container blocked accident of cage crashing in cage guide for solving existing mine hoisting system, the lighter causes substantial equipment to damage, can cause great personnel casualty accidents when serious, have a strong impact on mine safety, a kind of mine hoisting container fender guard is provided; The utility model is by, coder (1), current transducer (2), and limit switch (3), PLC (4), fault alarm and interlocking (5) constitute; The concrete technical scheme of the utility model is: coder (1) is arranged on the head sheave, and current transducer (2) is arranged on the motor, and limit switch (3) is arranged on the cage guide, and PLC (4) is arranged in the winding houses; Signal by coder (1), current transducer (2), limit switch (3) is sent into PLC (4), in PLC (4) internal analysis and judgement; Send into fault alarm and interlocking (5) in PLC (4) internal analysis and judgement back signal, fault alarm and interlocking (5) arrive gig master electric-control system with signal output; The environment for use temperature-40 of coder (1) ℃-+40 ℃; Limit switch (3) is selected the magnet contactor with direction memory function for use.
The beneficial effects of the utility model are: 1, can satisfy the control requirement of mine to elevator system, native system control accuracy height, safe and reliable; 2, can realize the automation and the intellectuality of mine hoisting system; 3, can relatively in time report to the police and locking the back according to the position of lifting container and the running state analysis of gig; 4, can guarantee the safety of mine lifting personnel and lifting means.
Description of drawings
Below in conjunction with accompanying drawing to originally being described in further detail:
Fig. 1 is a data transmission course diagram of the present utility model.
Among the figure, coder (1), current transducer (2), limit switch (3), PLC (4), fault alarm and interlocking (5).
The specific embodiment
As shown in Figure 1, coder (1) is arranged on the head sheave, and current transducer (2) is arranged on the motor, and limit switch (3) is arranged on the cage guide, and PLC (4) is arranged in the winding houses; Signal by coder (1), current transducer (2), limit switch (3) is sent into PLC (4), in PLC (4) internal analysis and judgement; Send into fault alarm and interlocking (5) in PLC (4) internal analysis and judgement back signal, fault alarm and interlocking (5) to gig master electric-control system, make gig stop and locking when breaking down, to guarantee the safe operation of gig signal output.
Claims (2)
1. a mine hoisting container fender guard is by coder (1), current transducer (2), and limit switch (3), PLC (4), fault alarm and interlocking (5) constitute; It is characterized in that: coder (1) is arranged on the head sheave, and current transducer (2) is arranged on the motor, and limit switch (3) is arranged on the cage guide, and PLC (4) is arranged in the winding houses; Signal by coder (1), current transducer (2), limit switch (3) is sent into PLC (4), in PLC (4) internal analysis and judgement; Send into fault alarm and interlocking (5) in PLC (4) internal analysis and judgement back signal, fault alarm and interlocking (5) arrive gig master electric-control system with signal output.
