ZZJ Type Intelligent Brake Detection Device With Mining Machine
Spare Parts
1. Product description of ZZJ type intelligent brake detection
device with mining machine spare parts
ZZJ type intelligent brake detection device is used to detect the
upper disc brake of hoist brake, which can detect the wear degree
of brake skin and fatigue degree of spring, and display it directly
in the form of numbers. When the brake wear and spring fatigue
exceed the set alarm value, output a switch signal to inform the
upper electronic control system, and detect the digital flashing on
the module to indicate the module alarm. The detection module is
intelligent, which can upload the digital quantity and alarm state
to the upper computer by means of communication (the corresponding
hardware and software should be added).
2. Product parameters of ZZJ type intelligent brake detection
device with mining machine spare parts
(1) System composition: each pair of gates consists of a detection
module and two sensors to form a detection unit; Each brake base is
installed with a control box, according to the brake base installed
on the logarithm, the control box loaded with the corresponding
number of detection modules; The control boxes are connected in
parallel through cables, and a power supply module provides the
working power.
(2) Installation: the control box is installed on the brake base;
The sensor is installed in the rear of the brake seat, so that the
sensor detection shaft is always on the top of the brake seat; The
sensor is connected to the corresponding detection module.
(3) Connection methods: each control on test module on the bottom
of the box has a 6 line terminals, terminal are defined as shown in
figure: left 12 v | | 0 v | | D1 and D2 | D | -- - | D right;
Including 12 v | | | 0 v to provide the 12 v power supply; | | | D2
D1 is a pair of dry contact, is used to output alarm signal; | D |
-- - | D is communication terminals. The 6-wire terminals in
several control boxes are connected together. Each detection module
has a 3-wire wiring terminal on the left and right sides for
connecting signal cables to the left and right sensors. Terminal
and sensor connection as shown in figure: | | left palm black | |
right.
(4) Detection parameters:
maximum distance: 25mm
Detection error: 0.1mm
(5) Dial setting: each detection and to the right of the module has
an 8-bit dial, is used to set the detection module parameters, as
shown in figure: left | | S1 S2 | S3 | S4 | S5 | S6 | S7 | S8 |
right.
As follows:
The ON value is 1 when the dial is up, and the ON value is 0 when
the dial is down |
|
S1, S2, S3, and S4 form a four-digit binary address |
|
S5 is the brake skin wear alarm value setting | 0 is 1.5mm, 1 is 2.0mm |
S6 is spring fatigue alarm setting | 0 is 0.5mm, 1 is 1.0mm |
S7 is the choice of brake skin wear alarm mode
| 0 is the alarm when one side reaches the alarm value |
1 is the alarm when the sum of both sides reaches 2 times of the
alarm value |
S8 is the last module setting | The last module is set to 1 and the rest to 0 |
(6) Debugging method: After installation, for the first time in
opened state, adjust the sensor position, before and after the
detection module is shown in the near 20.0, continue to press the
reset button for about 2 seconds on the test module, test module
display on 0.0, here is zero, after testing it to zero, as negative
said the size of the brake shoe clearance, positive number
indicates the degree of spring fatigue, When the set value of alarm
is reached, the alarm will be reported. After each switch
adjustment, the reset key must be pressed to clear. Under the
condition that the sensor's detection axis is fully released, press
the reset button on the detection module continuously for about 2
seconds, and the display will be 00.0. Then press the sensor's
detection axis, and the display will be 00.0 -- 24.9. This display
is used for the installation of the new brake skin.
(7) The alarm output mode is A pair of dry contacts with A capacity
of 0.5A, which are closed with alarm and disconnected without
alarm.
