- Use and model meaning
- QT1B-□□□/□-□ series crane console, mainly used for AC 50HZ rated voltage 380V and below and DC voltage 220V and below main circuit and control circuit, control hoisting transport machinery and similar conditions of electrical control equipment Motor starting, speed regulation, braking and commutation.
The meaning of the model and representative is as follows: - classification
2.1, according to the combination of controllers:
according to the number of controllers; full cam console; hybrid console;
2.2, according to the number of controllers: two controller console; three controller console; Four controller console; five controller console; six controller console;
2.3, fixed way: fixed console; rotary console. The rotary console is more widely used in applications such as gantry cranes. - Structural features and principle of action
The console is mainly composed of left and right control boxes, seats and bases. The control box has four specifications and six mechanisms (four controllers can hold four controllers, and six cabinets can hold six controllers). The height of the seat and the inclination of the backrest can be adjusted freely, and can be folded and turned to make the road clear. The left and right control boxes and seats are screwed on the base or directly mounted on the chassis of the cab, which can be removed. Easy to overhaul.
Each contact group of the controller in the console adopts double breakpoint contacts, and has a good arc extinguishing device. Each contact group is combined in the form of plug-in rhyme, and the arrangement is reasonable, so that the lead wires, wiring and maintenance are better.
The operation of the console is driven by two sets of gears by the joystick, so that the two controllers can be driven and driven simultaneously. The outlet of the handle is equipped with a dust-proof sealing device. The operating positions of the front, rear, left and right, and lifting can be divided into 1-6 gears according to the actual use requirements. The maximum number of contacts is 23, and the additional components of the upper cover of the box are installed. For various signal systems for controlling other movements of the crane.
The console handle operation is flexible, reliable, and the positioning is obviously accurate, and has a zero-position self-locking device. The self-locking function of the zero-seven-bit position has two functions, that is, the self-locking lever can be lifted to operate normally; After the handle is rotated by 15°, it will remain free from self-locking, and then resume self-locking after recovery to ensure safe driving or parking.
The rotary console uses a rotating device, and the rectification order console is operated with the foot in the range of 120° (ie, 60° left and right), and the corner is arbitrarily left to ensure that the operator has direct line of sight and no dead angle.
