Abstract
The invention discloses a pneumatic deicing device for a railway tunnel. According to the device, an expansion bolt penetrates through a mounting hole to fix a water diversion strip coated with a deicing coating to the position under a tunnel roof arch seam, an ice breaking plate is suspended below the water diversion strip through a hinge and a rivet, when a train passes through the tunnel, the ice breaking plate is pushed by wind pressure to swing to knock off icicles, and it is guaranteed that the icicles cannot invade the discharge area of a contact net.
Description
Technical field
The present invention relates to a kind of mechanical deicing device, be specifically related to a kind of railway tunnel hammer drill ice production apparatus.
Background technology
Place cold in the winter time, due to gap leakage between railway tunnel roof arch and arch, tunnel top will form icicle, when icicle invades the high-voltage contact net region of discharge set up in railway tunnel, will discharge, cause traction substation tripping operation power-off, interrupt train operation, the accident of even occur contact net localized burn, blowing.Electrified railway tunnels deicer for this reason described in existing CN203128955U patent, is made up of housing, heater element, temperature controller, temperature pick up, top board, base plate, gusset, warming plate and reflectance coating etc., and this device is by electrical heating ice-melt; Deicing device of railway tunnel described in CN102536319A patent, is made up of hanging basket, supporting plate, motor, reductor, bent axle, connecting rod, crossbeam and rope etc., and this device drives crossbeam swing to beat ice by motor.Above two kinds of deicers all exist complex structure, costly with need by the shortcoming of electric energy, former capital is not widely applied, and current railway systems deicing is still manually to beat ice.
Summary of the invention
The present invention for overcome existing deicing device of railway tunnel exist deficiency a kind of pneumatic tunnel deicer is provided, this deicer not only structure is simple, lightweight, price is low and deicing time adopt wind energy alternative electric energy that is safer, environmental protection.
The present invention is for realizing above object, adopt following scheme: a kind of railway tunnel hammer drill ice production apparatus, comprise buttress above railway tunnel, this buttress is provided with arch seam, described buttress is provided with deicer, and it is that " mountain " font water diversion article, cross section are that " fourth " font is beaten slab and connected water diversion article and hinge and the rivet of beating slab that this deicer comprises the cross section being fixed on arch seam place.
Preferably, described water diversion article comprises upper plate, the side wing of symmetrical consolidation and the first junction plate of middle consolidation, and wherein upper plate is curved, which is provided with installing hole; Side wing plate face is del, parallelly with on the buttress of side wing corresponding position is provided with groove of cutting off the water supply; Described slab of beating comprises the transverse sheet of bottom and the second junction plate of transverse sheet Ban Mian center consolidation, and wherein the first junction plate is by hinge and rivet interlacement.
Preferably, described transverse slat width is less than water diversion article width.
Preferably, the expansion bolt of fixing upper plate and buttress is provided with in described installing hole.
Preferably, described water diversion article and beat slab and be plastic material, wherein water diversion article smears de-icing coating.
Beneficial effect of the present invention:
1, the present invention compared with prior art, and structure of the present invention is simple, easy to use, with adopting wind energy alternative electric energy that is safer, environmental protection during deicing, saves energy spending;
2, the present invention adopts the water diversion article of plastic material and beats that slab quality is light, cheap, electrical security is good and low heat conductivity, and the heat release on drainage strip of anti-sealing is freezed;
3, the present invention adopts del flank and smears de-icing coating, reduces the bonding force of plate face and icicle, increases water flow velocity, guides icicle in flank inverted triangle bottom corner simultaneously, is convenient to and beats slab coordinate deicing;
4, the present invention arranges groove of cutting off the water supply on the buttress at flank top, is convenient to guide current to flow into flank;
5, the slab width of beating that the present invention adopts is less than water diversion article width, prevents icicle from growing adhesion transverse slat, causes dozen slab to fix;
6, result of use of the present invention is remarkable, is convenient to promote and use.

Detailed description of the invention
A kind of railway tunnel hammer drill ice production apparatus as illustrated in the drawing, comprise buttress above railway tunnel, this buttress is provided with arch seam, described buttress is provided with deicer, and it is that " mountain " font water diversion article 3, cross section are that " fourth " font is beaten slab 7 and connected water diversion article 3 and hinge 5 and the rivet 6 of beating slab 7 that this deicer comprises the cross section being fixed on arch seam place; Described water diversion article 3 comprises upper plate, the side wing of symmetrical consolidation and the first junction plate of middle consolidation, and wherein upper plate is curved, which is provided with installing hole 2; Side wing plate face is del, parallelly with on the buttress of side wing corresponding position is provided with groove 8 of cutting off the water supply; Described slab 7 of beating comprises the transverse sheet of bottom and the second junction plate of transverse sheet Ban Mian center consolidation, and wherein the first junction plate is connected with rivet 6 by hinge 5; Described transverse slat width is less than water diversion article 3 width; The expansion bolt 1 of fixing upper plate and buttress is provided with in described installing hole 2; Described water diversion article 3 and beat slab 7 and be plastic material, wherein water diversion article 3 smears de-icing coating 4.
Embodiment, in Fig. 1, deicer is fixed on the vault of center, tunnel through the installing hole 2 of water diversion article 3 by several expansion bolts 1, and water diversion article 3 liang of flanks are del, is conducive to water to del bottom corner place stream, beats slab 7 and block below top, tunnel;
In Fig. 2, water diversion article 3 material is that plastics cross section is for falling " mountain " font, surface scribbles de-icing coating 4, beating slab 7 material is that plastics cross section is for falling " fourth " font, water diversion article 3 is arranged on immediately below the arch seam of the break joint of two arches, above two flanks, vault is carved with groove 8 of cutting off the water supply, forcing arch seam to ooze the water got off can only along groove 8 of cutting off the water supply, the flank of water diversion article 3 flows down, water diversion article 3 first junction plate with beat slab 7 second junction plate and adopt hinge 5, rivet 6 connects, beat slab 7 transverse sheet width and be less than water diversion article 3 width, avoid icing adhesion, beat the contact net region of discharge that slab 7 transverse sheet setting height(from bottom) does not invade below.
In Fig. 3, beat slab 7 cross section for falling " fourth " font, there is performance of going for a drive, when train passes through in railway tunnel high speed, the air flow at high speed that train promotes in tunnel forms wind, it take hinge axis as centre swinging that blast promotes to beat slab 7, exceedes the icicle playing slab 7 egative film and hits down, ensure that icicle can not intrusive contact net region of discharge by length.
