Description
Technical Field
The utility model relates to a gas sensor safety application technical field, in particular to over-and-under type gas sensor cable suspension device.
Background
At present, mine mining gradually steps into deep areas, and the concentration of toxic and harmful gases is higher and higher. As a monitoring device for poisonous and harmful gas in a mine, a gas sensor is vertically hung above a roadway in a position where wind current is stable, and the strict installation definition is provided in the coal mine safety regulation: namely, the height from the top plate of the roadway is not more than 300mm, and the height from the side wall of the roadway is not less than 200 mm; the distance between the heading face and the coal face is required to be less than 5m, and the coal face is required to be in the range of a top cutting line. Such safety control regulations require frequent installation and removal of the gas sensor. This brings about potential safety hazards to coal mining: firstly, frequently ascending operation moving and calibration after the datum plane exceeds 2 m; parameter errors caused by non-standard suspension positions; and thirdly, the damage to the instrument in the simple hanging process. In order to realize safe construction, convenient installation and maintenance and not influence the accurate use of instruments. Nonstandard operation in the time of adjustment, replacement and position change must be reduced, and the safety accident of falling of personnel which may occur in the process of ascending operation is avoided. A lifting type gas sensor hanging device is specially designed.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model aims to provide a lifting type gas sensor hanging device which has the characteristics of simple structure, low cost and flexibility.
In order to realize the purpose, the utility model discloses a technical scheme is:
a lifting type gas sensor hanging device comprises a supporting rod 1 fixed on the side wall of a roadway through a fixing rod, wherein a telescopic rod 2 is inserted in the supporting rod 1; the support rod 1 is fixedly connected with the telescopic rod 2 through a fixing bolt; the support rod 1 is provided with a roller 4 with an operating handle 3, the top end of the telescopic rod 2 is provided with a fixed pulley block, the roller 4 is connected with the fixed pulley block through a steel wire rope 5, and the fixed pulley block is used for hoisting a gas sensor 8 through the steel wire rope 5.
The fixed pulley group comprises a guide pulley 6 and a balance fixed pulley 7 which are horizontally arranged at the top end of the telescopic rod 2.
The support rod 1 is made of six-part galvanized steel pipes, and the telescopic rod 2 is made of four-part galvanized steel pipes.
The support rod 1 is fixed on the coal bed bottom plate through a large supporting leg.
The top of the support rod 1 is contacted with the top plate through a support cap 9.
The utility model has the advantages that:
the hanging device for the gas sensor is simple in structure, low in cost, flexible in expansion, light in material and convenient to move, and eliminates the danger of ascending operation of constructors in the moving process of the gas sensor; standardizing the suspension accuracy of the instrument; the service life of the instrument is prolonged. The device can obviously improve the working efficiency and the accuracy of the sensor after being fixed, and ensure the safe operation of personnel and the accurate measurement of instruments.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1: including fixing bracing piece 1 on the lateral wall of roadway through the dead lever to and the telescopic link 2 of cartridge in bracing piece 1, bracing piece 1 passes through fixing bolt fixed connection with telescopic link 2, and the installation has gyro wheel 4 of action handle 3 on the bracing piece 1, and the fixed pulley group is installed on 2 tops of telescopic link, is connected through wire rope 5 between gyro wheel 4 and the fixed pulley group, hoists each sensor 6 through wire rope 5.
The support rod 1 is made of six-part galvanized steel pipes, and the telescopic rod 2 is made of four-part galvanized steel pipes.
The fixed pulley block comprises a guide pulley 6 and a balance fixed pulley 7 which are horizontally arranged at the top end of the telescopic rod 2.
The telescopic rod 2 is fixed on the side wall of the roadway through the fixing rod, and the supporting cap 9 is in contact with the top plate, so that the stable regulation of the device on the side wall of the roadway is ensured.
The steel wire rope 5 passes through the nuts fixed on the support rod 1 and the telescopic rod 2.
The utility model discloses a theory of operation:
when using, select suitable position in the tunnel in advance, then fix bracing piece 1 on the tunnel lateral wall through a plurality of dead levers, adjust the height of lift of telescopic link 2 after that, confirm high back, through fixing bolt with bracing piece 1 and telescopic link 2 fixed connection together, then hoist and mount gas sensor 8 on wire rope 5, have gyro wheel 4 of handle 3 through the operation, utilize the effect of fixed pulley group, it can to rise gas sensor 8 to required height.
When the gas sensor 8 needs to be adjusted and replaced, the length of the steel wire rope 5 is changed by operating the roller 4, so that the gas sensor 8 is lowered to a certain height; with the extension or the retreat change of the tunnel, the support rod 1 and the telescopic rod 2 are fixed at a new position again by detaching the fixed rod.
