Description

A kind of tongue snow shed of motion bar of the protection goat for track switch

Technical field

The utility model relates to railway switch snow shield field, particularly, relates to a kind of tongue snow shed of motion bar of the protection goat for track switch.

Background technology

At present, electrical heating turnout snow melting system is one of element of extremely frigid zones device for changing points, and the installation site by its snow melt bar, is probably divided into: on slide plate, heat and heat on the web of the rail of stock rail two kinds of device for melting snow.

The STDR-G type turnout snow melting system that Beijing Southwest Jiao great Sheng Yang Science and Technology Ltd. produces is comprised of station control terminal, switch board, isolating transformer, electrical heating elements etc.; That electric heating heating element (heating strip) is arranged on to the web of the rail place of the stock rail of track switch, on the locking frame of external locking device, when there is snowfall or variations in temperature, system can automatic or manual startup electric heating snow melting circuit, with reach by between tongue and stock rail, the effect of the locking frame place snow melting of external locking device, thereby reach the effect that guarantees Snowfall track switch equipment normal conversion.But still there is the defect of the following aspects in this snow-melting system:

1, the accumulated snow of the towing point place of track switch (track switch three bars) fails to consider design device for melting snow, when accumulated snow is deposited in three bar place of track switch, will directly have influence on the conversion of track switch;

2, due to the power limited (peak power 2650W) of its snow melt bar, so when tongue is under repulsion state, fail to melt near the accumulated snow of one end, tongue bottom on slide plate;

3, owing on the locking frame above the external locking device of tongue, heating strip being installed, after snow melting Cheng Shui on locking frame, take advantage of a situation toward dirty, drip on external locking device and can condense into ice cube afterwards, the accumulation of ice cube can make external locking device when operation, produce larger resistance.

Eventually the above, at the towing point (three bars) of track switch and the position of external locking device, all do not have device for melting snow, and after snowing, the towing point of track switch and external locking device position still also will be used and manually be carried out snow removing and just can guarantee that the normal dress of track switch changes.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.

As shown in Figure 1 and Figure 2, the tongue snow shed of the motion bar of the protection goat for track switch the utility model proposes, wherein, fix on the ground track switch comprising and spaced sleeper 1, be arranged on two stock rails 2 and two tongues 3 between two stock rails 2 on sleeper 1, article two, a side of stock rail 2 is provided with the goat 4 being arranged on adjacent two sleepers 1, and goat 4 drives tongue 3 to move between two stock rails 2 by motion bar 41; Fixed cover 51 and the telescopic cover 52 that is connected to middle fixed cover 51 both sides in the middle of this tongue snow shed comprises, middle fixed cover 51 and telescopic cover 52 are erected on two adjacent sleepers 1, two telescopic covers 52 are connected with the tongue 3 of both sides respectively, to complete the sealing to region between two tongues 3.

In actual use, goat 4 is arranged on a side of track switch conventionally, in the utility model, and the installing plate 6 that arranges on adjacent sleeper 1 that two intervals are arranged and extend along the bearing of trend of sleeper 1, installing plate 6 is fixed on sleeper 1, and goat 4 is erected on these two installing plates 6.Above-mentioned snow protection device covers the motion bar 41 of goat 4 and other relevant device, and when running into snowfall, the device being covered by snow protection device can not be subject to the impact of snowfall and can not turn round, thereby guarantees that goat 4 drives tongue 3 normally to move.

Tongue snow shed is the snow protection device between two tongues 3, and role is that the region between two tongues 3 is closed completely, and ice and snow is blocked on outside tongue snow shed.Concrete mounting structure is as follows:

Middle fixed cover 51 is fixedly connected with sleeper 1, and two telescopic covers 52 are removably connected with middle fixed cover 51 respectively, and two telescopic covers 52 are removably connected with two tongues 3 respectively.

Because tongue 3 can move, the snow protection device therefore contacting with tongue 3 must be can be flexible structure.In the utility model, adopted telescopic cover 52 to be connected with two tongues 3 respectively, and fixed cover 51 transition in the middle of adopting in the middle of two telescopic covers 52.Middle fixed cover 51 is fixed on sleeper 1 motionless, and when tongue 3 moves left and right, the telescopic cover 52 that both sides connect is by stretching to coordinate adjusting, guaranteed that overlay area can not be exposed to due to the movement of tongue 3 outside, played good snow defence effect.

As shown in Figure 1, in a specific embodiment of the present utility model, list: middle fixed cover 51 has bottom and from the upwardly extending sidepiece in both sides of bottom, the bottom of middle fixed cover 51 is fixed on sleeper 1, and two telescopic covers 52 are removably connected with the sidepiece of middle fixed cover 51 respectively.The zone line of the middle fixed cover 51 of this kind of structure can in height not take too much space, avoided the projecting member of the train bottom by tongue 3 and the possibility of its shock.In the middle of being positioned at, the sidepiece on fixed cover 51 both sides extends upward, and to guarantee being connected between telescopic cover 52 and tongue 3, and assurance telescopic cover 52 can not snap in the gap of tongue 3 bottoms when tongue 3 moves.

Particularly, in the utility model, listing a kind of telescopic cover 52 is organ cover.According to the structure of organ cover self, can be set to a side and 51 grafting of middle fixed cover by organ cover, opposite side is fixing by U-bolt and tongue 3.

Organ cover and middle fixed cover 51 pegged graft and can be realized by various structures, for example, on middle fixed cover 51, is provided with draw-in groove, organ cover one side along on the card falcon that can peg graft with draw-in groove is set, by coordinating of card falcon and draw-in groove, realize fixing of organ cover.In addition, also can be on organ cover fixed connection apparatus, be for example fixed on the framework of organ cover one side, the structure that can connect with the sidepiece of middle fixed cover 51 is set on framework, can realize equally the clamping with middle fixed cover 51.

In sum, the tongue snow shed of the motion bar of the protection goat for track switch the utility model proposes, by snow shed in the middle of arranging and telescopic cover, region between two tongues is covered in, make snow or dissolve after snow-broth can not fall into snow protection device inside, therefore can not freeze the inner parts such as motion bar, guarantee the normal operation of the internal parts such as motion bar, save artificial snow removing, guaranteed the normal operation of track switch.

Below describe by reference to the accompanying drawings preferred embodiment of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.

It should be noted that in addition each the concrete technical characterictic described in the above-mentioned specific embodiment, in reconcilable situation, can combine by any suitable mode.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible combinations.

In addition, between various embodiment of the present utility model, also can be combined, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
