Mine Hoist TCK Magnetic Switch,
60Hz magnetic switch,
265VAC Wire Rope magnetic switch
Lifter TCK magnetic switch series
TCK series magnetic switch is used for mine single rope and multi-rope hoist as wellbore switch, also suitable for other mechanical equipment.
The TCK series of magnetic switches are non-mechanical contact magnetic proximity switches. It consists of a magnetic sensor and an electronic circuit and an output switch. When the magnetic detector permanent magnet enters the sensing area of the TCK switch magnetic sensor, the TCK switch acts and outputs a switching signal by the action of the magnetic field. The output signal reflects the position and direction of movement of the detector and acts as a stroke control signal for the control system.
TCK series magnetic switches are available in two types and four types of general-purpose and explosion-proof special types:
The block diagram of the TCK magnetic switch is shown in Figure 1. They use sensitive and reliable magnetic sensors and microelectronics with high magnetic sensitivity, high resolution and wide response frequency. The circuit design adopts redundant structure and high anti-interference technology, and adopts switching power supply. The power supply voltage is 50-60Hz 85~265VAC. All circuits are cured by epoxy resin in cast aluminum or cast copper switch housings, fully sealed, waterproof and resistant. TCK magnetic switch has adopted a series of advanced design techniques and process technologies, so it has achieved high technical indexes and performance, and is suitable for various mines. There is no need to repair in the mine shaft. There are two methods for safely using the TCK magnetic switch on the mine single rope and multi-rope hoist: permanent magnet magnetic field source method and wire rope magnetic field source method. Both of these uses directly detect where the lifting container is actually located. Both methods can be used at the same time, with electrical control equipment to ensure safe and accurate operation of the hoist. This note focuses on these two methods of use.
TCK-1 type magnetic switch;
TCK-2 type magnetic switch;
TCK-3 and TCK-4 retaining magnetic switches.
TCK-1 type magnetic switch, when the external S magnetic field acts on the magnetic sensor, the switch operates and converts for 2 seconds.
|TCK-3 magnetic switch
|Mine single rope and multi rope hoist for shaft switch, also applies to other mechanical equipment.
When it is stationary, it is in the transition state, and it loses the magnetic field and is automatically reset. Similar to the general mechanical momentary action type push button switch, the press is converted, and the release is automatically reset.
The TCK-2 magnetic switch recognizes the direction of magnetic field motion. When the magnetic sensor detects the external magnetic field in the N-S pole direction, the switch acts and switches for 2 seconds. When the zero crossing is still, it is in the transition state, and the external magnetic field is lost, and the reset is automatically performed. The S-N pole direction magnetic field zero crossing does not convert.
TCK-3 and TCK-4 retaining magnetic switches have different magnetic fields.
The TCK-3 retaining magnetic switch has two states that can be maintained. When the external S-pole magnetic field acts on the magnetic sensor from bottom to top, the switch-switching movable contact is turned on with the upper end, indicating that the red light is on, and this state is maintained. This state is maintained even if the external magnetic field is lost, the switch is powered on, or the power is lost. When the external S-pole magnetic field acts on the magnetic sensor from top to bottom, the switching movable contact is connected to the lower end, indicating that the green light is on, and remains in this state until the next time from bottom to top. The S-pole magnetic field acts on the type 3 magnetic switch. The magnetic switch switches and can maintain various states, similar to the force of the mechanical toggle switch.
TCK-4 type hold type magnetic switch, when the magnetic sensor detects the external action magnetic field N-S pole direction magnetic field zero crossing, the switch switch moving contact is connected with the upper end, indicating that the red light is on, this state is maintained. When the external magnetic field S-N pole direction magnetic field crosses zero, the switch converts the movable contact to the lower end to indicate that the green light is on and keeps this state. The TCK-4 type magnetic switch has an accurate narrow-field magnetic field zero-crossing conversion characteristic and high positioning accuracy.
