2 main purpose and scope of application
Ztj127 hoist gate clearance protection device for coal mine is applicable to the protection and on-line monitoring and display of the disc gate clearance of mine hoist

major function
Display function
a) The clearance value of 0-24 brake shoes is 0-9
99mm
b) Display winch running speed 0-13
5m/s
c) Display brake oil pressure of hydraulic station
d) Display 0-9 points of dot signal (display this memory and display last points)
Protection function
The monitoring device is suitable for the wear monitoring of hoist winch brake shoe,
The main functions include real-time monitoring the brake clearance and pipeline oil pressure of each brake, recording fault information, voice reminder and log query
Main technical indicators include:
1
In order to monitor the return oil braking parameters of the hydraulic station, an oil pressure sensor is installed to monitor the secondary braking pressure in the hydraulic braking system

2
Install a brake clearance sensor on each brake shoe to measure the brake clearance based on the brake disc
When the displacement distance exceeds 2mm, it can give a voice reminder
The measurement range of the brake clearance sensor is 0 ~ 10mm and the error ≤ 2%。 The brake clearance sensor adopts digital displacement sensor, integrates can bus communication interface, and transmits digital data to the host

3
It can monitor the temperature of the brake disc, remind of overtemperature, and the threshold can be set by itself

4
Overspeed protection function: when the lifting speed exceeds 15% of the max speed, the optical signal indicates the action of the control relay

5
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 equipment operation

6
Protection function of lifting direction substation
7
Record query shall not be less than 90 days, and communication interface shall be added

Monitoring range of brake shoe clearance: 0
01mm ~ 10
00mm
Level 1 brake oil pressure monitoring range: 0
01Mpa ~ 10
00mpa
Monitoring range of secondary brake oil pressure: 0
01Mpa ~ 10
00mpa
Display the lifting speed, stroke, operation status, lifting hook number, etc
of the hoist
Displays the lifting direction of the hoist
Gate sticking pressure monitoring function
Idle time monitoring function (accuracy 0
001 s)
Drum deflection monitoring function (accuracy 0
01mm)
The brake shoe clearance exceeds the limit and is locked for the next start-up
Industrial Ethernet networking function (optional)
Fault state memory function: in case of brake shoe clearance overrun, overspeed, depth indicator failure and other faults, the display instrument will remember the name, time and relevant data of the fault
