Abstract
A curve laneway central line pointer that can point the direction of the curve laneway (tunnel) of the mine and the well is provided. An extension rod is adjusted in an outer fixed rod and is connected with a main body rod piece through a hinge, the outer fixed rod is connected with a pull rod through the hinge, the pull rod and a point rod can slide up and down in a groove of the main body rod piece through a sliding hinge, so as to make the extension rod rotate along the outer fixed rod around the main body rod piece or fold the rod piece of the extension rod into the groove of the main body rod piece. Once the curvature radius and the cyclic drilling footage of the curve laneway are determined, the length (Alpha value) of the extension rod can be determined; the included angle (Beta value) of the extension rod and the main body rod piece can be determined, and the length (Alpha value)of the extension rod can be regulated to the specified value, furthermore, the deformation of a triangle which is formed by the pull rod, the outer fixed rod and the main body rod piece can make the Beta angle be positioned accurately. The regulation of the central line pointer can realize the precise positioning and direction of each cycle cross section of the curve laneway.
Description
Affiliated technical field
The purpose of this utility model provide a kind of in down-hole, mine curving tunnel (tunnel), be used to refer to instrument, especially to each circulation section of curving tunnel (tunnel) can be accurately fixed in, the curving tunnel center line director that accurately points to.
Background technology
At present, the orientation method in coal mine lower curve tunnel is: make an enlarged drawing, and mark the distance that one group of center line is helped to curving tunnel two on a plurality of circulation sections, turn round by controlling changeable distance and workman's operative skill, this orientation method is unfavorable for the moulding and the rapid construction in tunnel, and often need ground survey engineering technical personnel frequent to on-the-spot unwrapping wire, thereby influence is produced.
Summary of the invention
In order to overcome the deficiency that existing line-putting method can not accurately point to each circulation section, the utility model provides a kind of curving tunnel center line director, in can not only accurately deciding each circulation section of curving tunnel, and can also accurately point to.
The technical scheme that its technical matters that solves the utility model adopts is: expansion link is regulated in the fixed bar outside, and by the hinge link to each other with the main body rod member, the external fixation bar links to each other with pull bar by hinge, pull bar can upper and lowerly slide respectively in main body rod member groove by the hinge of sliding, expansion link is taken in the main body rod member groove around the rotation of main body rod member or with it with the external fixation bar, the sensing bar slides in main body rod member groove or rotation by the hinge of sliding, and can point to.Determine the radius-of-curvature and the just definite length of telescopic bar of cyclic advance of curving tunnel; Just determine the angle of expansion link and main body rod member.And expansion link long (a value) can be transferred to setting, than the big leg-of-mutton distortion that long pull bar, external fixation bar and main body rod member are formed, expansion link is accurately located around the angle (β angle) that the main body rod member rotates.The β angle that changes expansion link a value and rotate around the main body rod member is regulated and is pointed to bar, makes this director be applicable to that the center line of curving tunnel on each circulation section of different curvature radius and cyclic advance points to.
The beneficial effects of the utility model are: curving tunnel center line director directly to each circulation section of curving tunnel accurately fixed in, accurately point to again simultaneously, the site work personnel can directly use the center line director to point to.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further specified.
Figure of description is the structural drawing of curving tunnel center line director.
Among the figure: 1. main body rod member, 2. pull bar, 3. expansion link, 4. external fixation bar, 5. center line points to bar, 6. pipe level, 7. hinge, 8. folding rod, 9. in expansion link reading chi, 10. angular readings chi, 11. point to bar reading chi, 12.13. hinge, the 14.15. hinge of sliding, 16. fixed screws.
Embodiment
When determining the radius-of-curvature of curving tunnel and cyclic advance, the length a value of interior expansion link and the angle β value of interior expansion link and main body rod member have in fact just been determined, by interior expansion link reading chi 9, according to a value, determine interior length of telescopic bar, and fix interior expansion links with fixed screw 16.According to the β value, the hinge 14 of sliding makes the big leg-of-mutton distortion of forming than long draw, external fixation bar, main body rod member, and expansion link is accurately located.By pointing to bar reading chi 11, adjust the direction of pointing to bar 5, can point to.
Two hole F and B are arranged on the main body rod member, a hole A is arranged on the folding rod.The distance of adjacent holes is cyclic advance (b).On (end) plate of top, set up point (for ease of explanation, main body rod member and folding rod have only been drawn three holes) according to F, B and A three holes.
Pipe level 6 steam bubbles are the precision that is used for improving director between two parties.
Folding rod 8 is set makes director folding, be convenient to director and carry by hinge 7.
Reading chi 9 is used for regulating length of telescopic bar.
10 reflections of reading chi are slided and are cut with scissors 14 stroke, decide according to the β angle.
Main body rod member both sides have groove, can take in the groove internal fixation with pointing to bar by the hinge 15 of sliding, and when the hinge 14 of sliding moves downward, pull bar, external fixation bar can be taken in the groove, regulate fixed screw 16, expansion link can be taken in the external fixation bar, are easy to carry.
Claims (4)
1, curving tunnel center line director, it is characterized in that: expansion link is regulated in the fixed bar outside, and by the hinge link to each other with the main body rod member, the external fixation bar links to each other with pull bar by hinge, pull bar and sensing bar are respectively by the hinge upper and lower slip in main body rod member groove of sliding, regulate and point to the bar sensing, pipe level and hinge are housed in the main body rod member.
2, curving tunnel center line director according to claim 1 is characterized in that: expansion link is the concentric rod member of an one with the external fixation bar, and expansion link is decided can freely stretch in the bar outside, by fixed screw expansion link is fixed.
3, curving tunnel center line director according to claim 1, it is characterized in that: external fixation bar, pull bar and main body rod member are formed a triangle, when pull bar slided in main body rod member groove, the expansion link of handling in the external fixation bar rotated around the main body rod member, accurately located for its angle.
4, curving tunnel center line director according to claim 1 is characterized in that: expansion link, external fixation bar, pull bar, sensing bar can take in the main body rod member groove by the connection of hinge and the slip of the hinge of sliding.
