Abstract
The utility model provides an energy -conserving snow melt ware of railway switch, including heating pipe, temperature sensor, power cord, sensing screw rod, sealed lid, sleeve, connecting leg nut, refractory seals glue, high temperature resistant seal ring, hollow double threaded screw, cover pipe thread, protection tube, nut cap, temperature controller. The utility model discloses snow melt organ pipe head department at weak link adopts sealing device to protect it, and the tie point of external power supply cable conductor all in protection device, is protected power transmission cable in the lump, has reduced the cable and has been dug possibility disconnected, that steal, adopt temperature controller, work as temperature sensor determine and be higher than to set the temperature to the pipe temperature, meeting automatic cutout power, otherwise the power transmission is heated. These two kinds of technological improvement and applied meeting greatly reduced power maintenance cost also alleviate workman's intensity of labour in the bigger degree, reach and prevent drawing, prevent fever, three kind energy -conserving efficiency.
Description
Technical field
The utility model relates to railway transport field, particularly a kind of railway switch energy-saving snow-melting device.
Background technology
Winter, plant area's melting snow at railroad switches device played very important effect in transit, analyzed from snow melter damaged condition in recent years, damaged points two kinds.One is that great majority all damage at tube head, and through dissection and analysis, around track switch, job execution is more, and slightly firmly just tube head resistance wire and cable connector place are broken, we cannot repair again, and a pipe has just been thrown away in vain.Another kind is heating tube dry combustion method, because stop power transmission scheduled order restriction, so snowpack is not very large sometimes, pipe has burnt red electricity and also sent always, and pipe resistance wire blows and damages, Frequent Troubles, and hidden trouble of equipment is given prominence to.
In addition, when current electric energy is in short supply, nearly more than 2000 snow melters are run at certain plant area scene, and every root pipe power 2KW, if do not control the function of power supply according to lower snowfall, a large amount of wastes of electric energy certainly will be caused.
Summary of the invention
The purpose of this utility model is to provide a kind of railway switch energy-saving snow-melting device, improve snow melter quality, reduce the spoilage of snow melter, improve the stable operation ability of snow-melting device for railway turnout in winter, reduce equipment failure rate and improve conevying efficiency, saving electric energy simultaneously.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of railway switch energy-saving snow-melting device, comprise heating tube, temperature pick up, power line, sensing screw rod, seal cover, sleeve, connecting leg nut, refractory seals glue, refractory seals packing ring, hollow double threaded screw, cover pipe thread, protection tube, nut cap, temperature controller, described seal cover is fixed on one end of sleeve, and connecting leg nut is fixed on the other end of sleeve; One end of hollow double threaded screw is screwed onto on the internal thread of connecting leg nut, and the other end is connected with nut cap by screw thread; Refractory seals packing ring is fixed with between connecting leg nut and hollow double threaded screw; The end of heating tube enters sleeve pipe through seal cover, and passes the temperature pick up of inside pipe casing, is connected with power line; Heating tube by screw and temperature pick up fastening; One end of sensing screw rod is connected with temperature pick up, and the other end is connected with power line by wire; One end of power line enters sleeve pipe through nut cap and refractory seals packing ring, is connected with sensing screw rod and heating tube, and the other end connects temperature controller; Protective casing is socketed in the outside of power line, and the protective casing part stretched in hollow double threaded screw links with the sleeve pipe being fixed on hollow double threaded screw inside and connects; Being filled with refractory seals glue by the confined space formed between seal cover, sleeve, connecting leg nut, refractory seals packing ring.
Compared with prior art, the beneficial effects of the utility model are:
A kind of railway switch energy-saving snow-melting device, volume is little, lightweight, snow removing performance is good, long service life, easily install, and effectively improves the stable operation ability of snow-melting device for railway turnout in winter, reduces equipment failure rate and improve conevying efficiency.The utility model adopts sealing device to be protected at the snow melter tube head place of weak link, power transmission cable, all in protective device, is protected by the tie point of external power supply cable in the lump, reduces cable and is dug possibility that is disconnected, that steal; Adopt temperature controller, when temperature pick up detects the temperature of tube temperature higher than setting, meeting automatic cut-off power, otherwise power transmission is heated.These two kinds of technological improvements and application can reduce power equipment maintaining cost greatly, also alleviate the labour intensity of workman to a greater extent, reach anti-and draw, burn-out-proof, energy-conservation three kinds of effects.
