The heating device has convenient installation, flexible configuration, good manufacturability, high reliability, long service life, obvious snow-melting effect and convenient maintenance and use, thereby ensuring the traffic safety of the railway in cold region.

Description

Track switch snow melt heater

Technical field

It is a kind of railway switch control checkout equipment, particularly track switch snow melt heater that the utility model belongs to.

Background technology

The northern China cold district, especially area, northeast, the heavy snow that continue winter covers rail, track switch, and train driving is in unsafe state, once caused miss the bus, a lot of accidents, the especially bitter lesson that took place to cause casualties because of the sleet snow disaster in 08 year such as derail because of sweeping away snow.In Harbin Railway Bureau and field, Shenyang Railway Bureau station, winter, field, whole sometimes station was flooded by thick snow, has a strong impact on train driving when snowing heavily, and the personnel that have to set out to sweep away snow, and labour intensity is very big, both bothered, and dangerous; If midnight the bust heavy snow, then can cause more burden; This problem is never effectively solved.Domestic have some track switch heating products, and system is perfect inadequately, and is very simple and crude, do not have and should produce effect; Extremely complexity is installed, needs special slide plate; The electrical heating elements life-span is short especially; Manually control needs the special messenger to guard, poor stability completely.

Summary of the invention

The purpose of this utility model provides a kind of good manufacturability, reliability height, maintenance and track switch snow melt heater easy to use.

The purpose of this utility model is to realize like this, track switch snow melt heater, at least comprise fire-bar and anchor clamps, it is characterized in that: described anchor clamps comprise the up knob geometrical clamp, descend the handle geometrical clamp, go up the fire-bar geometrical clamp, descend the fire-bar geometrical clamp, last fire-bar geometrical clamp and following fire-bar geometrical clamp are fixed with fire-bar, and up knob geometrical clamp and following handle geometrical clamp will be gone up the web of the rail place that fire-bar that fire-bar geometrical clamp and following fire-bar geometrical clamp fix is fitted in basic rail respectively.

Described fire-bar is a bluff body, long 13mm, wide 5.5mm.

Described fire-bar skin is the thick metal shell of 0.3mm, and internal layer is heater and insulation materials, and an end of fire-bar has lead-out wire, and the outer silicon rubber spiral that adopts of lead-out wire protects.

Feature of the present utility model: fire-bar adopts flat structure, increased heat transfer area, adopted the metal shell of 0.3mm that heater and insulating material heights compression are encapsulated simultaneously, and outlet at one end, the spiral protection of silicon rubber is adopted in the protection of outlet wire external layer, has extremely strong rotproofness and ageing resistance.And fire-bar is fitted in the web of the rail place of basic rail by the anchor clamps that comprise up knob geometrical clamp, time handle geometrical clamp, last fire-bar geometrical clamp, following fire-bar geometrical clamp.Its advantage is: (1) is easy for installation, is convenient to on-site maintenance; (2) flexible configuration, this system adopts advanced modular design concept, and fire-bar and installation folder have all formed seriation, are convenient to maintenance and expansion; (3) long service life, fire-bar can reach 10 year life-span under normal the use; (4) two bars are installed, and heat time heating time is short, and the snow melt effect is obvious, has saved electric energy.The utility model is applicable to domestic various existing railway switch, and the access control system accumulated snow on switch closure section tongue, stock rail and the slide plate that can effectively melt away makes the track switch can normal conversion, has ensured the traffic safety of cold district railway.

The specific embodiment

As shown in Figure 1 and Figure 2,1 is fire-bar up knob geometrical clamp; 2 is handle geometrical clamp under the fire-bar; 3 is last fire-bar geometrical clamp; 4 is fire-bar; 5 are following fire-bar geometrical clamp.With upper and lower fire-bar geometrical clamp 3,5 and upper and

lower handle grip

1,2 fixing two fire-bars 4 up and down, make two fire-bars 4 closely connected respectively in the web of the rail 7 places of basic rail 6.Various sectional fixtures have good elasticity, have just well met the requirement of expanding with heat and contract with cold of fire-bar.Northern China is heavily loaded track switch mostly, and tongue is changed frequency height, adopts at stock rail web of the rail installed inside fire-bar 4, for the maintenance work of railway is provided convenience.

As shown in Figure 3, Figure 4, fire-bar adopts flat structure, compares with the heating element of tubulose, and flat tubular heating element is gathered around bigger contact surface, has increased heat transfer area, and this conduction for heat is very useful; Adopted the metal shell of 0.3mm that heater and insulating material heights compression are encapsulated simultaneously, and outlet at one end, the spiral protection of silicon rubber is adopted in the protection of outlet wire external layer, has extremely strong rotproofness and ageing resistance.

As shown in Figure 5, in order not influence the closely connected of tongue and stock rail, various fire-bar geometrical clamps and handle grip adopt 1.2mm high-quality steel spring plate to make, and good elastic effect is arranged, and have solved the problem of expanding with heat and contract with cold of fire-bar; Consider the vibrations of track switch when crossing car simultaneously, various geometrical clamps, handle grip have adopted the hangnail structure, this with regard to strong guarantee track switch heater stability in use.
