Line is connect with the measurement display instrument (14).
The elastic anchor head (11) includes cover board (1), limit drawstring (2), scroll spring (3), telescopic pin (4), bracket
(5) it is mounted on bracket (5) with spring retaining sleeve (6), the cover board (1), is formed between the cover board and bracket and accommodate scrollwork
The cavity of spring, the spring retaining sleeve (6) is slidably mounted at the bottom of bracket (5), and passes through limit drawstring (2) and cover board
(1) it is connected, the scroll spring (3) is mounted on spring retaining sleeve, in the installation that the two sides of the bracket (5) are slided respectively
Have a telescopic pin (4), each telescopic pin (4) is corresponding a scroll spring (3)；The spring retaining sleeve (6) is located at bracket (5) outside
The part in portion is connected with wirerope.
The measurement display instrument (14) is fixedly mounted on lower sleeve portion (13), and the circuit part of the measurement display instrument includes
CPU control unit and the detection part being connect with CPU control unit, power management section and display portion；The CPU control
Unit processed uses MSP430 series monolithic；The display portion uses three high brightness numeral method data.
The utility model has the advantages that:
1, stability is improved using the restoring force of scroll spring using elastic anchor head.
2, the problems such as preventing original anchor head unbalance stress or falling off, guarantee the accuracy of measurement result.
3, phenomena such as preventing slide rheostat from being broken by palisades abrasion using casing protection.
4, the workload for reducing coal miner also avoids the case where human error occur, improves monitoring precision
And monitoring efficiency.
5, be not in because coal dust covering or measuring scale get rusty caused by can not observing monitor fail the case where sight
Survey is also more intuitive,
6, monitor is irradiated using mine lamp, can shows current absciss layer value immediately.
