QKT45-100/250(Original ModelQKT45-3)

Mining General Driver Controller

Name、Model and Meaning 


Scope of application and working conditions


QKT45-100/250 mining general driver controller (Original model QKT45-3), this product is used for 5T/7T wire-type resistance speed locomotive, as the starting speed, parking and reverse of locomotive.

※ This product is based on the QB/LX 004-2006 corporate standard.

※ This driver controller is suitable for the following working environments:

   1) The altitude does not exceed 1200m; (to negotiate with the user when it is exceeded).

   2) The ambient temperature is -20 ° C ~ +40 ° C (when the monthly average temperature is +25 ° C);

   3) The relative humidity of the surrounding air does not exceed 95%;

   4) There is no flammable gas and coal dust explosion mixture occasion;

   5) There are no harmful gases sufficient to damage the insulation and corrosive metals;

   6) An impact acceleration of not more than 30m/s2 with respect to the longitudinal direction of the locomotive.

   7) Sinusoidal vibration with a frequency f of 2~50HZ relative to the vertical, longitudinal and lateral directions of the locomotive, the amplitude A of which is not greater than:

   2≤f≤10Hz A=25/f(mm)

   10≤f≤50Hz A=250/f2(mm)

   8) Installed in the battery-type mining electric vehicle driver controller room.


Technical Parameters


※Rated voltage: 250V (DC)

※Rated current for long-term work: 100A

※ Weight: 78kg

※Outer shape and installation size (see exterior installation dimension drawing)


Structural features


The controller is rectangular, and the skeleton consists of two layers: bottom plate, partition plate, panel and support parts. The main contact element and the cam are mounted below the partition plate, and the reverse drum, the reverse contact and the interlocking position device are mounted below the partition plate. The panel is equipped with a horn button light switch, a main handle, and a reverse handle.

The main handle and reverse handle have the following interlocking requirements:

Only when the reverse handle leaves the “0” position, the main handle can be rotated. After the main handle leaves the “0” position, the reverse handle cannot move. Only when the handle returns to the “0” position, the reverse handle can move.


Operating Guide


After the engine, turn the light on and turn it on to the light position, pull the reverse handle to the double-set position, ring the horn, and then pull the hand wheel version to the first position of the lead direction, the locomotive slowly moved, with the hand wheel position advances, the speed gradually increases, when the trigger to the last position of the move,

The locomotive is traveling at full speed. When you stop, pull the wheel back to the "0" position ,when the power machine is cut off and the hand gate is switched on. Turn off the lights and get off the locomotive.

When the locomotive is driving to reduce speed or make movement, in addition to the machine system, it can also be used to act by electrical system, that is, the wheel of the wheel to the system of the movement, one-level and one-level movement, when the trigger to the last position, the maximum force.

If the No. 1 electric machine (front machine) causes a problem, the left hand will press the limit pin hand pointing under the reversed handle cap, The right hand will move the reverse handle to the rear position, and then the main wheel to lead the 1st position, the machine car can be empty load back repair,if NO.2 electric machine caused by a barrier, using the same blind method, the reverse handle is counter-positioned to the front machine, the wheel pull the first position, and the locomotive can be returned empty.


Use repairs and precautions 


※Check that the wires are properly linked and that the fasteners are tight

※Do not check to open the cover with electricity

※Control device installation, see (exterior and installation size figure)

※Check the control machine to disconnect automatic switch, off the power source can open the outer shell.

※Control machine must be regularly clean up, in order to clear the dust, build scale, avoid the edge of the surface climbing electricity.

※Each friction surface and rolling pieces of control machine must period plus a small amount of grease, in order to ensure the work of its parts, reduce less grinding loss.

※Due to the burning of the arc,contact surface is uneven,can be used to repair, with fine boring and sand cloth grinding to make its surface flat Light slips, but the assembly must meet the following requirements :

1)Its contact surface is less than the contact side to 80 % of the full length.

2)The difference between the contact and the head pair is not as large as Imm.

3)The contact opening distance>8mm.   

4)Touch Force >14 . 7N final pressure force > 29.4 N.

5)Compression overtravel> 2mm

6)The requirements of the open and closed character of the main contact (the main contact open-closed graph).
