And be not have position monitoring on the existing domestic various coal-winning machines, lean against traction transmission case inside exactly and design output shaft installation speed measuring device again, then through conversion, at last signal is passed to computer and handle.Adopt this mode to test the speed, link is more, and the error of generation is bigger; Damaged and also be not easy to change and maintenance.Ad hoc monitoring device causes mechanism complicated on the traction case, has taken the confined space on the coal-winning machine; Moreover be exactly that precision is not enough, perhaps be exactly that occupation space is bigger, the position of installation is undesirable, and structure is more loaded down with trivial details, is not easy protection, often damages in the use, and certainty of measurement is lower, has much all become ornaments, even becomes the new source of trouble.
The utility model content
The utility model is afraid of that the technical problem that will solve provides a kind ofly can be made the positioner device that tests the speed be applied on the coal-winning machine and can protect the positioner device that tests the speed to be suitable for complicacy and the abominable coal-winning machine of the working condition explosion-proof installing mechanism of positioner device that tests the speed.
In order to solve the problems of the technologies described above; The coal-winning machine that the utility model the provides explosion-proof installing mechanism of positioner device that tests the speed comprises encoder, and described encoder places by lid and cover and adopts in the sealing cover body that flame proof thread connects to form; The axle of described encoder is installed on the described cover through bearing and sealing device; Described cover is provided with anti-explosion cable turnover horn mouth, and described cover sealing is installed on the coal-winning machine housing, and described axle is in transmission connection through shaft coupling and connecting axle.
Be provided with locking pressing plate between described lid and the described cover.
It is on described cover, to be provided with wire hole that described anti-explosion cable passes in and out bell-mouthed structure, and sealing mat is located in the described wire hole, and platen is pressed in pad on the described sealing mat, and described platen is installed on the described cover through bolt.
Described cover sealing and fixing is installed on the adpting flange, and described adpting flange sealing and fixing is installed on the described coal-winning machine housing.
The axle of described encoder is installed on the described cover through the clutch shaft bearing and second bearing.
Adopt the coal-winning machine of the technique scheme explosion-proof installing mechanism of positioner device that tests the speed, this device is contained in the slow speed turbine stage of coal-winning machine, couple together through the gear shaft of shaft coupling with encoder and coal-winning machine.The outside of encoder have cover to its shield and with lid between be connected with flame proof thread.In the course of work of coal-winning machine; Through connecting axle and shaft coupling the rotating speed of coal-winning machine is delivered to the encoder place; By encoder it is detected; Output to ground in real time through cable and carry out analytical calculation detecting the anti-explosion cable turnover horn mouth of result through the right, thereby can measure the real-time speed of travel and the distance of coal-winning machine, carry out Long-distance Control.Adopt shaft coupling that this device is connected with the supporting axle of coal-winning machine, prevent that the axle center from not aligning; Axle is supported by two bearings, makes radially fixing, inner and be designed with sealing and carry out dustproof and waterproof; Adopt locking pressing plate to carry out the locking of flame proof thread.
In sum, the utility model is effectively explosion-proof, solves the explosion-proof difficult problem of encoder applies on coal-cutting machinery, can monitor the speed of the walking of coal-winning machine under the ore deposit, the distance of walking and the position of place support.Realize " few peopleization " and solve setting up the difficult characteristics of kinetic model, thereby the operating mode in the face of coal-winning machine detects the operating position of knowing coal-winning machine on ground, effectively boosts productivity and personnel's utilization rate.
