Abstract
The airtight front sensor erecting by overhang of a kind of underground coal mine, there is chute board, the same side at the forward and backward two ends of chute board has the major and minor pulley of axis and chute board lateral vertical respectively, driving-belt is connected with between major and minor pulley, head pulley there is crank, the chute board between major and minor pulley has the slideway along driving-belt, slideway has the slide block being connected in driving-belt, there is hanging rope the front end of chute board, and there is hanging cover rear end.The utility model has chute board, chute board there is transmission device, can firedamp sensor be hung on the ceiling in airtight front tunnel, can firedamp sensor be moved on to outside closed roadway entrance fence with the transmission device on chute board, staff need not enter and close in front panel, also need not ascend a height just firedamp sensor can be moved on to and carry out calibration and maintenance by the side of, make calibration and safeguard staff's personal safety of closing front firedamp sensor.
Description
Technical field
The utility model relates to a kind of underground coal mine sensor erecting by overhang, particularly the firedamp sensor erecting by overhang of enclosing wall front portion, a kind of coal mine gob.
Background technology
The front portion that rear enclosed wall is closed in coal mine gob have one section of tunnel (hereinafter referred to as: before closing), close the last period tunnel and have fence, likely there is the gas leaked out from goaf between fence and enclosing wall, easily can there is gas accident this section of tunnel inner accumulated in the gas leaked out.In order to the safety that underground coal mine is produced, ceiling before closing in tunnel there is sling point, sling point is hung with the firedamp sensor monitoring gas density, for ensureing that firedamp sensor works effectively, will carry out calibration to firedamp sensor weekly, every day will safeguard firedamp sensor devious.Calibration and when safeguarding, in the nearby operation of firedamp sensor.
Close front tunnel ceiling higher, after before closing, tunnel ceiling hanging hangs firedamp sensor, firedamp sensor is very large apart from the height on ground.In prior art, closing front firedamp sensor is positioningly hang on ceiling with erecting by overhang, with this erecting by overhang firedamp sensor hanging before closing tunnel ceiling on after, because hanging position is higher, in calibration with when safeguarding firedamp sensor, staff needs to enter in above-mentioned tunnel, under auxiliary with apparatus of ascending a height, ascend a height to and close near the flanking position of firedamp sensor below the ceiling of front tunnel, calibration and safeguard firedamp sensor.The toxic and harmfuls such as the gas that leaks out may be had because underground coal mine closes in front tunnel, staff enter close in front tunnel and the firedamp sensor before closing underground coal mine of ascending a height carries out calibration and upkeep operation time, be easy to cause the poisoning or security incident such as to suffocate.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and proposition one just can operate outward at fence, avoid the underground coal mine of security incident to close front sensor erecting by overhang before entering during firedamp sensor before calibration and maintenance are closed and closing.
The utility model realizes with the following method.
Underground coal mine closes front sensor erecting by overhang chute board, the same side at the forward and backward two ends of chute board has the major and minor pulley of axis and chute board lateral vertical respectively, driving-belt is connected with between major and minor pulley, head pulley there is crank, chute board between major and minor pulley there is the slideway along driving-belt, slideway has the slide block being connected in driving-belt, there is hanging rope the front end of chute board, and there is hanging cover rear end.
During installation, sling point installed by ceiling before closing in tunnel, before closing the fence in tunnel outer above ceiling fixed pulley is installed, hanging cover in chute board rear end of the present utility model is hung on the sling point before closing in the fence of tunnel on ceiling, the hanging rope of the utility model chute board front end under fixed pulley draws, firedamp sensor is connected on slide block.After installation, on the ceiling closing in front tunnel of chute board rear end of the present utility model hanging, forward shake crank, by auxiliary pulley firedamp sensor being transplanted on chute board rear end, pull the hanging rope of the utility model chute board front end under fixed pulley draws, allow on chute board front end and rise, chute board front end is lifted on the ceiling in the outer tunnel of fence, allow chute board close to the ceiling in tunnel, hanging rope is fixed.
The length of the utility model chute board is equivalent to the ceiling closed in front tunnel and installs sling point to the distance outside access adit fence.
During use, untie hanging rope, chute board front end is allowed to decline, chute board front end is dropped to the height that staff's hand can touch, reverse shake crank, firedamp sensor by the other head pulley being transplanted on chute board front end of auxiliary pulley, then firedamp sensor is before closing outside access adit fence, staff's access adit fence before closing just can implement calibration and upkeep operation outward, after calibration and upkeep operation complete, forward shake crank again, by auxiliary pulley firedamp sensor being transplanted on chute board rear end, pull the hanging rope of the utility model chute board front end under fixed pulley draws again, allow on chute board front end and rise, chute board front end is lifted on the ceiling in tunnel, allow chute board close to the ceiling in tunnel, hanging rope is fixed.
The utility model has chute board, chute board there is transmission device, can firedamp sensor hang close front tunnel ceiling on, firedamp sensor can be moved on to the transmission device on chute board closes outside front access adit fence, staff need not enter that closing in front panel also need not ascend a height just can move on to calibration by the side of firedamp sensor and safeguard firedamp sensor, makes calibration and safeguards that the work personal safety of closing front firedamp sensor is guaranteed.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the schematic front view that a kind of underground coal mine proposed according to scheme of the invention of the present utility model closes front sensor erecting by overhang;
Fig. 2 is the schematic top plan view of Fig. 1;
Fig. 3 is the using state schematic diagram that the utility model is arranged on when closing front cave body ceiling.
Detailed description of the invention
In Fig. 1, Fig. 2, underground coal mine closes front sensor erecting by overhang chute board 1, the same side at the forward and backward two ends of chute board has the major and minor pulley 2,3 of axis and chute board lateral vertical respectively, driving-belt 4 is connected with between major and minor pulley, head pulley there is crank 5, the chute board between major and minor pulley has the slideway 6 along driving-belt, slideway has the slide block 7 being connected in driving-belt, there is hanging rope 8 front end of chute board, and there is hanging cover 9 rear end.
In Fig. 3, sling point 11 installed by ceiling 10 before closing in tunnel, before closing, above the fence in tunnel outer 12, fixed pulley 13 installed by ceiling, hanging cover in chute board 1 rear end of the present utility model is hung on the sling point before closing in the fence of tunnel on ceiling, the hanging rope 8 of the utility model chute board front end under fixed pulley draws, firedamp sensor 14 to be connected on slide block 7.After installation, on the ceiling closing in the fence of front tunnel of chute board rear end of the present utility model hanging, forward shake crank 5, by auxiliary pulley firedamp sensor being transplanted on chute board rear end, pull the hanging rope of the utility model chute board front end under fixed pulley draws, allow on chute board front end and rise, chute board front end is lifted on the ceiling outside access adit fence, allow chute board close to the ceiling in tunnel, hanging rope is fixed.
