Abstract
The utility model relates to a mine winch electric rope releasing control device. The control circuit is composed of a start switch K2, a stop switch K1 and a magnetic switch K4. Both terminals of the control circuit are connected with the input terminal of a power circuit, a magnetic switch K5 is connected with an electric motor D, both output terminals of the magnetic switch K5 are connected with both terminals of the reducing transformer coil curl L1 of a rope releasing control circuit, one terminal of the reducing transformer L2 is connected with the ground, and the other terminal of the reducing transformer L2 is connected to the input terminal of a boosting transformer coil curl L3. The other terminal of the coil curl L3 is connected with a rope releasing wheel, and the output terminal of the boosting transformer coil curl L4 is connected with a magnetic switch K3 in parallel. The utility model has simple structure, reasonable design, easy installation and low cost. When the device has the fault of rope releasing, the mine winch electric rope releasing control device can cut off the power automatically to carry out a safety braking, and the goal of safe and reliable using is reached.
Description
Technical field
The utility model relates to the automatically controlled slack rope control setup of a kind of well winch.
Background technology
At present, the rope creep protection of China's mine hoist generally adopts travel switch formula sensor, presses travel switch behind the slack rope, connects control and warning circuit, the employing that has size steel rope touch sensor; Big steel rope is pressed onto on the little steel rope during slack rope, connects control and warning circuit by the contact resistance of big or small steel rope.Control warning and warning circuit by time relay, intermediate relay, electric whistle is formed, and the condition of its action is by being the connection by sensor.But in actual applications, because various odjective causes, often produce damages of transfiniting of sensor contact resistance, faults such as line interruption make and control and warning circuit can't be connected, normal operation, and itself also can break down its control and warning circuit sometimes.These faults can not in time be found and be handled sometimes, until expanding as serious accident.
State Intellectual Property Office is the mine hoist slack rope device that bulletin on the 19th was arranged in 1993 5; repacking is to adopt the infraluminescence emission; the mine hoist rope creep protection device that adoptor and instrument container are formed; adopt infrared emission; adoptor is made the contactless type sensor; circuit in the instrument box is handled the signal of sensor, starts the purpose that controlled safety return circuit reaches rope creep protection by the outage executive circuit at last.But this device exists structure comparatively to become assorted, the more high weak point of cost.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and the automatically controlled slack rope control setup of well winch a kind of simple in structure, safe and reliable is provided.
In order to achieve the above object, the technical solution adopted in the utility model is: described control circuit is by starting switch K2, halt switch K1, magnet-switch K4 forms, it two is connected on the input end of power circuit, magnet-switch K5 links to each other with motor D, the output two ends of magnet-switch K5 and slack rope control circuit step-down transformer coil L1 two ends join, the mouth of step-down transformer L2, one end ground connection, the other end is connected to the input end of step-up transformer coil L3, the other end of coil L3 is connected with the slack rope wheel, and the mouth of step-up transformer coil L4 also meets magnet-switch K3.
The utility model has the advantages that:
Simple in structure, reasonable in design, easily install, with low cost, when this device slack rope breaks down, promptly cut off the electricity supply automatically, implement safety arrestment, reach safe and reliable purpose.
Description of drawings
Fig. 1 is the utility model block diagram;
Fig. 2 is the utility model schematic circuit diagram;
The specific embodiment
Below in conjunction with accompanying drawing the embodiment that this practicality makes the transition is described in further detail.
By Fig. 1-Fig. 2 as can be known, this practicality is transition: described control circuit is by starting switch K2, halt switch K1, magnet-switch K4 forms, it two is connected on the input end of power circuit, magnet-switch K5 links to each other with motor D, the output two ends of magnet-switch K5 and slack rope control circuit step-down transformer coil L1 two ends join, the mouth of step-down transformer L2, one end ground connection, the other end is connected to the input end of step-up transformer coil L3, the other end of coil L3 is connected with slack rope wheel 1, and the mouth of step-up transformer coil L4 also meets magnet-switch K3.
It is work like this that this practicality makes the transition:
During with power control switch DK closure, press starting switch K2, at this moment, magnet-switch K4 adhesive, also adhesive of magnet-switch K5 simultaneously, electrical motor D entry into service, step-down transformer L1, the 380/36 end ground connection of intensity coil of voltage transformer L2 that brings into operation, the other end is connected with step-up transformer coil L3, an end-coil of step-up transformer 36/380 links to each other, and the other end of step-up transformer coil L3 is connected to rope sheave.When loosening, winch rope touches holder during rope sheave, when giving birth to 380 volts of voltages of intensity coil generation of pressure transformer 36/380, make magnet-switch K3 adhesive, indicator lamp is luminous simultaneously, magnet-switch K3 adhesive, and the normally closed contact self-insurance line that magnet-switch K3 itself is carried disconnects, magnetic starter K5 also disconnects simultaneously, the motor D outage is shut down, reach the safe and reliable purpose of the automatically controlled slack rope control of well winch, the accident that prevents takes place.
Claims (1)
1. automatically controlled slack rope control setup of well winch, by control circuit, motor, magnet-switch is formed, it is characterized in that: described control circuit is by starting switch K2, halt switch K1, magnet-switch K4 forms, it two is connected on the input end of power circuit, magnet-switch K5 links to each other with motor D, the output two ends of magnet-switch K5 and slack rope control circuit step-down transformer coil L1 two ends join, the mouth of step-down transformer L2, one end ground connection, the other end is connected to the input end of step-up transformer coil L3, and the other end of coil L3 is connected with slack rope wheel (1), and the mouth of step-up transformer coil L4 also meets magnet-switch K3.
