Description
Technical field
The utility model relates to a kind of jacking system, specifically a kind of firedamp sensor jacking system, belongs to firedamp sensor safety applications technical field.
Background technology
At present,, pernicious gas control monitor unit poisonous as a kind of mine, firedamp sensor should be hung vertically in the position of unstable airflow above tunnel, has strict installation definition: be namely not more than 200mm apart from back height, be not less than 300mm apart from tunnel sidewall in " safety regulations in coal mine "; Then be must ensure at driving face to meet head on to be less than 5m in distance, coal-face must be within the scope of break line.This Security Administration, certainly will require that the installation work of moving of firedamp sensor will be accomplished frequently to carry out.This just brings potential safety hazard to the colliery of coal seam, thick coal-layer mining: one is that reference plane is more than the ascend operation after 2m; Two is hanging position parameter errors caused lack of standardization; Three is to the damage that instrument causes in simple and easy installation process.In order to accomplish safe construction, convenient for installation and maintenance, do not affect the accurate use of instrument.Must reduce in adjustment, replacing and the operation lack of standardization in the change in location time, stop contingent personnel's fall safety accident in ascend operation process.
Utility model content
For above-mentioned prior art Problems existing, the utility model provides a kind of firedamp sensor jacking system, and structure is simple, with low cost, replaces the ascend operation phenomenon that firedamp sensor moves workmen in process; The precision that specification instrument hangs; Promote instrument service life.Greatly increase work efficiency and sensor fix after accuracy, guarantee personal security operation and the precise determination of instrument.
To achieve these goals, this firedamp sensor jacking system comprises the strut bar be fixed on by fixed link on the sidewall of tunnel;
And the expansion link be inserted in strut bar;
Described strut bar is fixedly connected with by bolt of rear end plate with expansion link;
Described strut bar is installed the roller with lever;
Fixed pulley group is installed on described expansion link top;
Be connected by steel rope between described roller with fixed pulley group;
By described steel rope lifting firedamp sensor.
Further, described strut bar is six points of galvanized steel pipes, and described expansion link is four points of galvanized steel pipes.
Further, described fixed pulley group comprises the leading sheave peace homeostasis pulley that level is arranged on described expansion link top.
Further, described expansion link is fixed on the sidewall of tunnel by fixed link.
Further, described steel wire penetrating is fixed in the nut on described strut bar and expansion link.
Compared with prior art, this firedamp sensor lifting device structure is simple, with low cost, by expansion link and the strut bar of insertable type, and the effect of roller and pulley, instead of the ascend operation phenomenon that firedamp sensor moves workmen in process; The precision that specification instrument hangs; Improve instrument service life.Substantially increase work efficiency and sensor fix after accuracy, ensure that the precise determination of personal security operation and instrument.
Accompanying drawing explanation
Fig. 1 is agent structure schematic diagram of the present utility model;
Fig. 2 is the lateral plan of Fig. 1;
In figure: 1, firedamp sensor, 2, fixed pulley group, 21, leading sheave, 22, balance fixed pulley, 3, expansion link, 4, bolt of rear end plate, 5, strut bar, 6, steel rope, 7, lever, 8, roller, 9, fixed link.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As depicted in figs. 1 and 2, this firedamp sensor jacking system comprises the strut bar 5 be fixed on by fixed link 9 on the sidewall of tunnel;
And the expansion link 3 be inserted in strut bar 5;
Described strut bar 5 is fixedly connected with by bolt of rear end plate 4 with expansion link 3;
Described strut bar 5 is installed the roller 8 with lever 7;
Fixed pulley group 2 is installed on described expansion link 3 top;
Described roller 8 is connected by steel rope 6 with between fixed pulley group 2;
Firedamp sensor 1 is lifted by described steel rope 6.
This firedamp sensor jacking system in use, suitable position is chosen in advance in tunnel, then by some fixed links 9, strut bar 5 is fixed on the sidewall of tunnel, then the adjustable height of adjustable telescopic rod 3, after determining height, is fixed together strut bar 5 and expansion link 3 by bolt of rear end plate 4, then firedamp sensor 1 is lifted on steel rope 6, by the roller 8 of operation with lever 7, utilize the effect of fixed pulley group 2, firedamp sensor 1 is risen to desired height.
When firedamp sensor 1 needs adjustment, replacing, changed the length of steel rope 6 by operated roller 8, thus make firedamp sensor 1 be reduced to certain height; Along with extension or the retrogressing change in tunnel, by removing fixed link 9, strut bar 5 and expansion link 3 are retightened in new position.
Further, according to the actual service condition of underground coal mine, described strut bar 5 is six points of galvanized steel pipes, and described expansion link 3 is four points of galvanized steel pipes.
Further, described fixed pulley group 2 comprises the peaceful homeostasis pulley 22 of leading sheave 21 that level is arranged on described expansion link 3 top.Steel rope 6 realizes lifting by the effect of the peaceful homeostasis pulley 22 of leading sheave 21 to firedamp sensor 1, ensure that firedamp sensor 1 fixing after stability and accuracy.
Further, described expansion link 3 is fixed on the sidewall of tunnel by fixed link 9.Be fixed on the basis on the sidewall of tunnel at strut bar 5 by fixed link 9, after the height of expansion link 3 is determined, also expansion link 3 can be fixed on the sidewall of tunnel by fixed link 9, more ensure that the steadiness of whole device, so more ensure that firedamp sensor 1 fixing after accuracy.
Further, described steel rope 6 is through in the nut be fixed on described strut bar 5 and expansion link 3.Effectively can prevent the swing of steel rope 6, directed effect is played to steel rope 6.
In sum, this firedamp sensor lifting device structure is simple, with low cost, instead of the ascend operation phenomenon that firedamp sensor moves workmen in process; The precision that specification instrument hangs; Improve instrument service life.Substantially increase work efficiency and sensor fix after accuracy, ensure that the precise determination of personal security operation and instrument.
