Deicing device of railway tunnel
Technical field
, belong to railway transport field.
Background technology
Connect China railways tunnel along the line, have the advantages that seepage is dripped, in cold district, every winter, these ice lollys of forming one by one that drip were suspended on the roof in tunnel, very easily make the transmission of electricity bare wire of below produce disruptive discharge, to railway transportation, bring very big danger.Generally adopt at present the method for manually beaing to remove ice lolly, as Qinling Tunnel has the special match-maker person that beats every year, carry out deicing operation, their working environment is arduous, dangerous large, deicing cost is high, and this original de-icing method has been not suitable with the needs that modernized railway is built.
Summary of the invention
The object of the invention is to design a kind of deicing device of railway tunnel, with this, substitute arduous manpower work.This device is lifted on the drip roof below in district of railway tunnel.Structure is comprised of hanging basket, supporting plate, motor, reductor, bent axle, connecting rod, crossbeam, longeron and rope.The structure of hanging basket is quadra, and the upper end of framework is fixed on tunnel with setscrew, is provided with supporting plate below hanging basket, supporting plate is the square plate body of a block length, with insulation materials, make, one section of top that is in transmission of electricity bare wire that supporting plate stretches out, produces electric discharge in case bent axle is close with transmission of electricity bare wire.Reductor is installed in hanging basket, and the sole of reductor is screwed on hanging basket.At a side mounted motor of reductor, a side of motor and speed reducer is fixedly linked and is integral, and the output shaft of motor is fixedly linked with the power shaft of reductor.In the running circuit of motor, be provided with timer switch, for opening and closing the timing running of motor and the duration of runs of control motor.Opposite side at reductor is installed bent axle, being shaped as of bent axle is L shaped, and one end of bent axle and the output shaft of reductor are fixedly linked and are integral, and two connecting rods are installed on the spindle nose of the bent axle other end, the connecting rod head of two connecting rod other ends, insertion and the pivot pin seat by pivot pin is fixedly linked respectively.Pivot pin seat is arranged on crossbeam.Pivot pin seat and crossbeam are fixedly linked and are integral.Pivot pin seat be shaped as U-shaped, on pivot pin seat, be provided with pin-and-hole, pin-and-hole is for pivot pin is installed.
The pipe that is shaped as one section of circular arc bending of crossbeam, longeron be shaped as straight-run of pipe, between two longerons, be connected with respectively several crossbeams, crossbeam and longeron are connected as a body.Crossbeam is all arranged near a side of ice lolly, utilizes the displacement of crossbeam to shoot down ice lolly.The structure that this longitudinal and transverse beam is connected as a body, for two, is separately positioned on the both sides of bent axle.Connecting rope on longeron, the upper end of rope is fixed on the roof in tunnel, and two structures that beam is connected as a body are in length and breadth passed through respectively one section of rope hanging below the roof in tunnel.
While needing deicing, if the startup interval time of good timer switch and the running time of motor, starter motor rotation, motor via reducer drives crankshaft rotating, the bent axle of rotation drives several cross bars to move back and forth by connecting rod, in the process of motion, cross bar shoots down the ice lolly of annex, thereby reaches the object of automatic de-icing.

The specific embodiment
As shown in Figure 1, 2, this device is lifted on the drip roof below in district of railway tunnel.Structure is comprised of hanging basket 1, supporting plate 2, motor 3, reductor 4, bent axle 5, connecting rod 6, crossbeam 7, longeron 8 and rope 9.The structure of hanging basket 1 is quadra, the upper end of framework is fixed on tunnel with setscrew, below hanging basket 1, be provided with supporting plate 2, supporting plate 2 is the square plate body of a block length, with insulation materials, make, one section of top that is in transmission of electricity bare wire 10 that supporting plate 2 stretches out, produces electric discharge in case bent axle 5 is close with transmission of electricity bare wire.At the interior installation reductor 4 of hanging basket 1, the sole of reductor 4 is screwed on hanging basket 1.At a side mounted motor 3 of reductor 4, a side of motor 3 and reductor 4 is fixedly linked and is integral, and the output shaft of motor 3 is fixedly linked with the power shaft of reductor.In the running circuit of motor 3, be provided with timer switch, for opening and closing the timing running of motor 3 and the duration of runs of control motor.Opposite side at reductor 4 is installed bent axle 5, being shaped as of bent axle 5 is L shaped, the output shaft of one end of bent axle 5 and reductor 4 is fixedly linked and is integral, two connecting rods 6 are installed on the spindle nose of bent axle 5 other ends, the connecting rod head of two connecting rod 6 other ends, insertion and the pivot pin seat 12 by pivot pin 11 is fixedly linked respectively.Pivot pin seat 12 is arranged on crossbeam 7.Pivot pin seat 12 and crossbeam 7 are fixedly linked and are integral.Pivot pin seat 12 be shaped as U-shaped, on pivot pin seat 12, be provided with pin-and-hole, pin-and-hole is for pivot pin 11 is installed.
The pipe that is shaped as one section of circular arc bending of crossbeam 7, longeron 8 be shaped as straight-run of pipe, between two longerons 8, be connected with respectively several crossbeams 7, crossbeam 7 and longeron 8 are connected as a body.Crossbeam 7 is all arranged near a side of ice lolly 13, utilizes the displacement of crossbeam 7 to shoot down ice lolly 13.The structure that this longitudinal and transverse beam 7,8 is connected as a body, for two, is separately positioned on the both sides of bent axle 5.On longeron 8, connecting rope 9, and the upper end of rope 9 is fixed on the roof in tunnel, and two structures that beam 7,8 is connected as a body are in length and breadth suspended in respectively the roof below in tunnel by one section of rope 9.
