Description
Technical field
The utility model is related to underground coal mine measuring device, specially a kind of telescopic multifunctional tunnel measuring device.
Background technology
In progress of coal mining, to ensure roadway construction quality and grasping underground surrounding rock stability current intelligence, each mine
It needs largely to be measured in process of production and roadway deformation monitoring, mine construction technical staff passes through between measurement anchor pole
Array pitch, the parameters such as length and rockbolt installation angle that leak outside pass through to ensure construction quality and analyze Underground pressure monitoring data grasp
Stope and improving stability of surrounding rocks in roadway.
In the daily measurement of mine and deformation monitoring work, survey crew is completed using steel tape, but steel tape does not have
Levelling and angle measuring function；On the other hand most of mine laneway surface displacement monitoring uses cross distribution point method at present, if lane
Help measuring point in road two（Two measuring points i.e. in horizontal direction）Using steel tape according to the simply levelling arrangement of the size with bottom plate distance,
Since roadway floor is not a horizontal plane and flatness is not relatively high, it is difficult to ensure that two measuring points are in same level.It measures
When generally use steel tape and measure line, since steel tape rigidity is relatively low, in addition travelling belt and head-room are larger in tunnel
Etc. factors limitation, cause worker's in-site measurement work difficulty, error larger, cannot really reflect deformation of the surrounding rock in tunnel situation.
Invention content
There are task difficulties in order to solve existing mine laneway measurement that big, the poor influence country rock of precision becomes for the utility model
The problem of shape monitors, provides a kind of telescopic multifunctional tunnel measuring device.
The utility model adopts the following technical scheme that realization：A kind of telescopic multifunctional tunnel measuring device, including
Stretch the body of rod made of the tube body grafting being sequentially reduced from left to right by several section diameters, and the tube body upper side wall positioned at left part is set
It is equipped with level meter, round angle scale is provided on the tube body front side wall of left part, round angle scale is provided centrally with receipts
Releasing box often saves and is both provided with graduation mark on the lateral wall of tube body.
When carrying out mine laneway measurement, the left end of the flexible body of rod is fixed on and measures target one end, from flexible body of rod right end
Extraction tube body is read up to the other end of its top contact measurement target, realizes the measurement of distance in order；Measure diameter
When smaller hole depth（Such as bolthole）, from right part, extraction tube body inserts in the hole up to bottom hole, is read；Carry out levelling work
When industry, it is a gang of that the right end of the flexible body of rod is fixed on tunnel, extraction tube body until another side in tunnel, by swing stretch the body of rod and
It observes level meter and realizes levelling work；When carrying out angle measurement（Such as rockbolt installation angle）, the body of rod that stretches is ensured by level meter
In horizontal position, the overlapped objects such as measurement line and the anchor pole in folding and unfolding wire box are extracted out, angle of inclination is read by round angle scale,
After being measured, measures line and automatically retract.Overcome existing mine laneway measurement there are task difficulties big, the poor influence of precision
The problem of surrouding rock deformation monitors.
The flexible body of rod is made of carbon fibre material.
Often section tube body is cone structure.
Graduation mark is and to be provided with transparent wear in scale slot made of scale slot.
The structure design ensure that the service life of graduation mark, it is not easy to be damaged.
It is reliable that the structure design of the utility model is reasonable, and distance in tunnel, level, angle and hole can be completed by a people
It is deep etc. to measure work, production efficiency is substantially increased, reduces labour cost, and rigidity is larger, lighter in weight, measurement long distance
It can guarantee that the body of rod is in straight line when from target, while the barrier top out of tunnel being convenient for extend through accurately to measure tunnel
The precision of width, measurement is increased dramatically, and has the advantages that simple in structure, easy to carry and multiple functional.
