1
2 main purpose and scope of application
The utility model relates to a brake shoe clearance monitoring device for hoist clearance protection in coal mines, which is suitable for protecting the disc brake clearance of mine hoists and on-line monitoring and display
Power on, displacement sensor, oil pressure sensor output 4 & mdash; 20mA signal is transmitted to the host through the communication module for data processing and converted into corresponding data
The real-time data of the hoist safety brake will be displayed on the screen online
When the brake shoe clearance of the hoist safety brake is 2mm larger and the brake oil pressure value is greater than the upper limit setting value and less than the lower limit setting value, the data will be analyzed and determined to output a prompt signal, and the device will send an audible prompt

The monitoring device is suitable for on-line monitoring and protection of gap wear of brake shoe of winch of coal mine hoist,
The main functions include real-time monitoring of brake shoe clearance, brake disc deflection, spring fatigue, idle time and pipeline oil pressure value of each brake, recording fault information, voice reminder and log query
The main technical indicators include: brake shoe braking on-line monitoring, brake clearance protection intelligent detection device
1
Real time online detection and synchronous display of gate clearance value, with accuracy within plus or minus 0
1mm;
2
On line temperature and vibration monitoring of main bearings of hoist winch motor, drum main shaft, reduction gearbox and crown wheel;
3
On line monitoring of disc brake shoe and disc brake shoe of hoist;
4
The brake clearance value is detected in real time, and when it exceeds the specified value (2mm), it will prompt and output the signal to the main control system in the form of dry contact (locking start-up), and the measurement accuracy is up to 0
01mm;
5
It has the functions of on-line monitoring and prompt protection of brake clearance overrun, brake shoe wear overrun, spring fatigue overrun, brake disc yaw, temperature (motor, reducer, drum main shaft bearing) and vibration (motor, reducer, drum main shaft bearing)
Audible and visual or voice prompt can be sent out after exceeding the limit, and the next start-up can be locked after exceeding the limit protection
At the same time, at least one dry contact of respective function output shall be reserved for future system expansion or provision to relevant other electric control equipment and devices;
6
Real time detection of spring pressure and prompt when the spring is strained;
7
Real time monitoring of brake disc deflection and prompt when exceeding the standard;
8
5000 fault records can be saved to facilitate maintenance personnel to monitor the faulty brake head;
9
The clearance curve value of each pair of brake heads can be saved;
10
Calculate the action times of each brake as a reference data for replacing brake disc spring and brake shoe;
11
Configure infrared temperature sensor to avoid the brake disc temperature being too high and the brake shoe being burnt out due to the brake not fully opened;
12
Real time online detection and synchronous display of braking oil pressure value, with an accuracy of plus or minus 0
1MPa;
In order to monitor the return oil braking parameters of the hydraulic station, install the oil pressure sensor to monitor the secondary braking pressure in the hydraulic braking system;
13
Self adjustment and setting of gate clearance parameters and over limit prompt function;
14
The parameter of brake oil pressure can be adjusted and set automatically, and the prompt function of exceeding the limit; Brake shoe clearance protection
15
Automatic correction function of gate clearance calculation error;
16
Fault self diagnosis function;
17
It can monitor the temperature of the brake disc, remind of over temperature, and the threshold can be set by itself;
18
Chaosu protection function: when the lifting speed exceeds 15% of the max speed, the optical signal indicates the action of the control relay;
19
Realize the display of real-time data such as brake clearance and oil pressure value, remind data query, remind or lock the hoist after exceeding the limit or failure
It has a three-dimensional dynamic monitoring picture, which realizes the consistency between the brake and the actual equipment and vividly reflects the operation of the equipment;
20
Online monitoring function of brake disc deflection;
