Description
Technical field
The utility model relates to underground coal mine planes to control field of measuring technique, and specifically a kind of portable underground coal mine is led
Line point.
Background technique
The mode of underground coal mine plane control measurement is traverse survey, laying form and the ground surface works measurement of underground conducting wire
It is almost the same, it is subdivided into back traverse (intersect back traverse), connecting traverse and three kinds of open traverse.Undershaft traverse survey operation behaviour
Making a ring critically important in step is reconnaissance (burying a little), due to coal mine down-hole tunnel particularity, in traverse survey operation " reconnaissance "
Usually notice that intervisibility is good, distance should not be too short between consecutive points, and convenient for placement instrument, and control point will be easy to save and be convenient for
It finds.Requirement in coal mine survey regulation to control point is generally located on solid rock top plate, and three o'clock at one group.Control point
(permanent point) is usually by top plate drilling, and the round steel that cross is carved at pre-buried top hammers into basement rock or less (aperture is greater than round steel diameter),
And it is secured with concrete backfill, end is exposed at top, and quick hardening cement or waterglass can be used to set up an office for special circumstances.Due to concrete
Timeliness is backfilled, the above-mentioned way permanently put must be selected on the day before observation and be buried, and underground survey multi-way is caused to do over again, additional to increase
Add workload.
Utility model content
The purpose of this utility model is to provide a kind of portable underground coal mine traverse point, convenient for the installation of instrument conducting wire,
To solve the problems of the prior art.
To achieve the above object, the utility model provides the following technical solutions: a kind of portable underground coal mine traverse point, packet
It includes the anchoring body of rod, casing, screw rod, bolt and sets string holes, casing is equipped with below the anchoring body of rod, is equipped with spiral shell below described sleeve pipe
Bar, the screw rod outer sheath are equipped with bolt, and the bolt end head is equipped with gasket, and fixed column is equipped with below the screw rod, described solid
Fixed column left and right ends are respectively equipped with sheath body, and the shroud base is equipped with bottom plate, is equipped with inside the sheath body and sets string holes.
Preferably, left side sheath body bottom end is equipped with cutting ferrule.
Preferably, right side sheath body bottom end is equipped with little spring, and the right side sheath body passes through described in little spring connection
Bottom plate.
Preferably, top is equipped with buckle on the left of the bottom plate.
Preferably, the cutting ferrule is mutually adapted with the buckle specification.
Preferably, the line assembly surface of setting below the fixed column is coated with insulating materials and reflexive fluorescent material.
Compared with prior art, the utility model has the beneficial effects that the utility model is realized and is surveyed using mechanical installation
Amount control point is surveyed when selecting, and accelerates the convenient installation of underground pilot point, reduces the workload of underground survey operation, is reduced
To the holding time in tunnel, it is convenient securely to set line, improves working efficiency.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1~3, in the utility model embodiment, a kind of portable underground coal mine traverse point, including the anchoring body of rod
1, casing 2, screw rod 3, bolt 5 and string holes 10 is set, anchors and is equipped with casing 2 below the body of rod 1, be equipped with screw rod 3, screw rod 3 below casing 2
