Abstract
The utility model discloses a kind of devices of mine sensors quick-replaceable calibration, including ratchet and sensor hanger, two fixed pulleys are arranged in interval on the tunnel top surface of mine, transition fixed pulley is respectively set in tunnel one side wall, wirerope is connected on sensor hanger, wirerope is wound together around each fixed pulley with the ratchet wheel shaft being mounted on tunnel side wall, ratchet is mounted in ratchet box, pawl is set in the top of ratchet box, slack rope pressure handle is set in the middle part of pawl top surface, positioning wire card is installed on the wirerope of sensor hanger.The utility model can once mounting in place, later maintenance, calibration and replacement will no longer ascend a height operation, reach sharp work, reduce the effect of security risk.
Description
Technical field
The utility model relates to a kind of devices of mine sensors quick-replaceable calibration.
Background technique
Non-coal mine downhole detection monitoring system is an important system in underground " six big systems ", wherein fixed biography
Sensor is the end-equipment of the on-site data gatherings such as carbon monoxide in monitoring and controlling system, wind speed, temperature.According to national related rule
It needs periodically sensor wire is verified and replaced calmly.
Fixed sensor replacement verification is a long-term and many and diverse job in non-coal mine downhole detection monitoring system,
Replacement and check-verifying period are half a year, and fixed sensor is mounted at the top of tunnel at present, and personnel are in replacement and checking procedure
In the environment of frequent high-rise working, there are biggish security risks.
Summary of the invention
The purpose of this utility model is to provide a kind of devices of mine sensors quick-replaceable calibration, being capable of once mounting
In place, later maintenance, calibration and replacement will no longer ascend a height operation, reach sharp work, reduce the effect of security risk.
The purpose of this utility model is achieved in that a kind of device of mine sensors quick-replaceable calibration, including spine
Wheel and sensor hanger, two fixed pulleys are arranged in interval on the tunnel top surface of mine, set respectively in tunnel one side wall
Transition fixed pulley is set, wirerope is connected on sensor hanger, wirerope is around each fixed pulley and is mounted on hole
Together, ratchet is mounted in ratchet box ratchet wheel shaft winding on road side wall, and pawl, pawl are arranged in the top of ratchet box
Slack rope pressure handle is set in the middle part of top surface, positioning wire card is installed on the wirerope of sensor hanger.
When the utility model is installed, suitable position is chosen according to head-room and fixes steel wire with positioning wire card, pawl leans on
Gravity is caught in the ratchet of ratchet, to guarantee that ratchet and cable drum will not pull ratchet anti-due to sensor gravity
Turn, enables sensor suitable location, after this covering device is installed, when replacing calibration working sensor, the sensor that need to be replaced
Be carried to related place, depress slack rope pressure handle, rotate counterclockwise manual rocking handle can by below the sensor at the top of tunnel extremely
Suitable position, unclamping slack rope pressure handle can position, and after replacement, rotate counterclockwise manual rocking handle, up to sensor to work
Operation is so far completed in position, easy to operate practical, and security risk is effectively reduced, improves work efficiency.Facilitate normal use and
Replace calibration.
Detailed description of the invention
The utility model is described in further detail below in conjunction with attached drawing.
Fig. 1 is the mounting structure schematic diagram of the utility model；
Fig. 2 is the schematic view of the front view of the utility model ratchet box.
Specific embodiment
A kind of device of mine sensors quick-replaceable calibration, as shown in Figure 1 and Figure 2, including ratchet 5 and sensor are hung
Frame 4, sensor 3 are mounted on sensor hanger 4.Two fixed pulleys are arranged in interval on the tunnel top surface of mine, in tunnel
Transition fixed pulley is respectively set in one side wall, is connected to wirerope 8 on sensor hanger 4, wirerope 8 is around described each
Fixed pulley be mounted on tunnel side wall ratchet wheel shaft winding together, ratchet 5 is mounted in ratchet box 1, ratchet box 1 it is upper
Pawl 6 is set in portion, slack rope pressure handle 7 is set in the middle part of 6 top surface of pawl, it is fixed to be installed on the wirerope of sensor hanger
Position steel wire card 2.Stirring slack rope pressure handle 7 can make disengagement between pawl 6 and ratchet 5 contact, and ratchet 5 is inverted, to put
Lower sensor hanger 4, otherwise rotating ratchet 5, rise sensor hanger 4, pawl 6 is caught in ratchet 5 by gravity, to ratchet 5
Carry out stop.
