Description
Technical field
The present invention relates to a kind of mining telescopic chi, belong to underground survey technical field.
Background technology
At present, for monitoring coal mine down-hole tunnel deflection, consider factor easily, workman often uses tape measure directly to measure, but its shortcoming is: (1) is when measuring tunnel roof and floor distance, tape measure can only hang on top board anchor net or other prop, have ignored the distance between prop and top board, produces certain error; (2) when tape measure is suspended in tunnel, due to the effect of wind, tape measure can swing everywhere, adds big error further; (3) when pullling tape measure, cannot accomplish that ruler place straight line ensures absolute level or vertical, measured result is also just more inaccurate.Therefore need to adopt one easy to carry, the ruler that measuring error is little is observed roadway deformation.
Summary of the invention
For overcoming the deficiencies in the prior art part, the invention provides a kind ofly to be easy to carry, mining telescopic chi that measuring error is little.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of mining telescopic chi, comprises mark straight instrument, main scale, the first secondary chi, the second secondary chi, the 3rd secondary chi, fourth officer chi and the 5th secondary chi.Except the 5th secondary chi, all main scales, secondary chi is front opening, tail end is closed, and the 5th secondary chi to be two ends all closed, and at all main scales, evenly scale mark is provided with outside secondary chi, when this shrinkage-rule is opened completely, to mark straight instrument outside surface scale registration for zero, the thickness of the straight instrument of mark is taken into account, scale reading evenly increases along main scale and five sections of secondary chis, spring and button is provided with near blind end place at all secondary chis, through hole is had at all main scales and the secondary chi other end and button place, when this shrinkage-rule is opened completely, button ejects by spring, occur appearing outside through hole.
The straight instrument of described mark and main scale orthogonal.
Described main scale, the first secondary chi, the second secondary chi, the 3rd secondary chi, fourth officer chi and the 5th secondary chi are hollow steel tube.
Described main scale, the first secondary chi, the second secondary chi, the 3rd secondary chi, fourth officer chi and the 5th secondary chi can be measured length and be 1m, and total range is 6m.
Therefore, beneficial effect of the present invention is embodied in: this mining telescopic chi can ensure that in measuring process ruler place straight line ensures absolute level or vertical, not easily bend simultaneously, affect little by wind, and can wall be close to, accurately record the distance of roadway's sides and roof and floor, after measurement, secondary chi can be regained again, conserve space, uses easy to carry.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1-marks straight instrument, 2-scale mark, 3-main scale, 4-button, 5-through hole, 6-spring, the secondary chi of 7-first, the secondary chi of 8-second, the secondary chi of 9-the 3rd, 10-fourth officer chi, the secondary chi of 11-the 5th.
Embodiment
Being easy to for making the present invention understand, below in conjunction with accompanying drawing, setting forth the present invention further.
As shown in Figure 1, a kind of mining telescopic chi, comprises the straight instrument of mark (1), main scale (3), the first secondary chi (7), the second secondary chi (8), the 3rd secondary chi (9), fourth officer chi (10) and the 5th secondary chi (11).Except the 5th secondary chi (11), all main scales (3), secondary chi (7, 8, 9, 10) front opening is, tail end is closed, and the 5th secondary chi (11) for two ends all closed, and in all main scales (3), secondary chi (7, 8, 9, 10, 11) outside is evenly provided with scale mark (2), when this shrinkage-rule is opened completely, to mark straight instrument (1) outside surface scale registration for zero, the thickness marking straight instrument (1) is taken into account, scale reading is along main scale (3) and five sections of secondary chis (7, 8, 9, 10, 11) evenly increase, at all secondary chis (7, 8, 9, 10, 11) spring (6) and button (4) is provided with near blind end place, at all main scales (3) and secondary chi (7, 8, 9, 10) other end and button (4) place have through hole (5), when this shrinkage-rule is opened completely, button (4) ejects by spring (6), occur appearing in through hole (5) outside.
Mark straight instrument (1) orthogonal with main scale (3).
Main scale (3), the first secondary chi (7), the second secondary chi (8), the 3rd secondary chi (9), fourth officer chi (10) and the 5th secondary chi (11) are hollow steel tube.
Main scale (3), the first secondary chi (7), the second secondary chi (8), the 3rd secondary chi (9), fourth officer chi (10) and the 5th secondary chi (11) can be measured length and be 1m, and total range is 6m.
When using mining telescopic chi of the present invention, to measure roof and floor distance, first straight for mark instrument outside surface is close to back, makes main scale place straight line keep vertical, then five sections of secondary chis are stretched out as required one by one, button ejects outside through hole by spring, can play fixing effect, till secondary chi touches roadway floor, then registration will be read, after measurement terminates, button is pressed and is back in through hole, the contraction of Collapsible ruler can be completed.The head-room observed due to actual needs and the width overwhelming majority are no more than 6m, and therefore mining telescopic chi of the present invention can meet the demands completely.
Therefore, beneficial effect of the present invention is embodied in: this mining telescopic chi can ensure that in measuring process ruler place straight line ensures absolute level or vertical, not easily bend simultaneously, affect little by wind, and can wall be close to, accurately record the distance of roadway's sides and roof and floor, after measurement, secondary chi can be regained again, conserve space, uses easy to carry.
