Description

The track switch automatic snow-removing device

Technical field

The utility model relates to a kind of railway transportation rail track switch snow-removing device.

Background technology

The railway transportation station, field track switch is indispensable, and in the cold weather place, track switch is not removed the snow, be prone to accidents, three kinds of methods are roughly adopted in the track switch snow removing, the one, manually to sweep away snow, the workman can hold besom and keeps on the track switch limit when snowing, along with the cleaning at any time of snowing, the 2nd, the workman carries portable snowblower on the body, and the course of work is identical with the former, and the 3rd, the electric heating snow removing, electrothermal tube is placed on the slide plate of special processing, energising makes the electrothermal tube heating, make the slide plate heating through conduction of heat, snow falls to dissolving thereon, and preceding two kinds of methods are simple, take artificial, poor reliability is cleaned untimely, dangerous big, the third method, the cost height, power consumption is big, safeguards, install all inconvenient.Reality need be designed a kind of device, solves the railway transportation track switch snow removing problem of cold district.

Summary of the invention

The purpose of this utility model is to remove the snow on the track switch, designs a kind of track switch automatic snow-removing device.

The utility model is realized by the following technical solutions.

Being provided with in collection snow groove, the collection snow groove has a little electrothermal tube, dissolves snow, and circuit turn-on connects electronic amplification circuit, starts blower fan, with the snow on the pneumatic cleaning track switch.

A kind of track switch automatic snow-removing device, it is characterized in that, a track switch snow removing box is respectively established on the left and right both sides of railway switch, track switch is provided with travel switch K2 on one side, track switch snow removing box is provided with collection snow groove, is provided with circuit junction K1 and electrothermal tube resistance R 3 in the collection snow groove, is provided with blower fan B1 or B2 in the snow removing box, be provided with the control circuit board that is made of transistor, relay, rectifier, resistance, electric capacity etc., its upper-part constitutes automatic control loop together with K1, K2; Track switch snow removing box is provided with blowing mouth, and the blowing of blower fan is arranged, direction aim at track switch branch, close the position, it is alternating current 220V that the utility model adopts power supply, 50HZ.

The utility model advantage is that it is simple in structure, low cost of manufacture, installation, use, easy to maintenance, adopt the utility model, have only in the winter time, and only snowy the time, just start blower fan, save electric energy, the track switch snow removing has realized automation, and its reliable operation can be eliminated the accident that track switch is caused because of accumulated snow.The utility model can also be used for the track switch of rail circuit transportations such as urban light rail, subway, and good application prospects is arranged, and has excellent popularization and is worth.

Description of drawings

Fig. 1 is one of the utility model circuit theory diagrams.

Fig. 2 is two of the utility model circuit theory diagrams.

Fig. 3 is a snow removing box structural representation.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is made and to describe in further detail.

A track switch is divided left and right both sides, Yi Bian closing, Yi Bian separately.One side separately must snow removing, does not remove the snow, and when needs are closing, can contact badly, lead to a disaster easily, thus must there be blower fan to start, blowing, snow removing; And the one side of closing originally, track switch also will be separated after switching, and also must have blower fan to start, blowing, snow removing; Therefore, a track switch snow removing box will be respectively established on left and right both sides of railway switch, below also claims the snow removing box, the snow removing box on one side of track switch, is provided with travel switch K2 to be bolted on the flange of rail, when track switch one side, closing as the left side, as Fig. 2, K2 turn-on relay J has the snow removing box inner contact J1 on the left side to disconnect, and blower fan B1 does not work, the snow removing box inner contact J2 closure that the right is arranged, power supply, blower fan B2 work, blowing, the blowing of track switch the right, snow removing; Conversely, track switch is swung to the right, travel switch K2 action is arranged, not conducting of relay J, the work of J1 normally closed contact, left side track switch snow removing box inner blower B1, power supply, blowing, snow removing, promptly track switch is being closed on one side, do not dry, needn't remove the snow, separately on one side, blower fan blowing, snow removing.A track switch will be established two snow removing boxes and a travel switch, and travel switch also can be established two, is contained on the track switch, utilizes its normally closed contact.

Blower fan B1, B2 are powered by alternating current 220V.In order to save electric energy, have only snowy the time, have only circuit turn-on, the power supply of relay Z1, Z is then arranged _1-1, Z _1-2Just closed, blower fan work is just arranged.

As shown in Figure 1, a R3 resistance is arranged, power supply, heating, it is located in the collection snow groove, and only when snowing winter, the snow that falls advances in the collection snow groove, dissolves into water, and quite K switch 1 turning circuit has the work of Z1 relay, Z _1-1, Z _1-2Junction closure just has blower fan B1 or B2 work, dries, removes the snow, does not snow, and nothing is avenged and dissolved in the collection snow groove, is not have blower fan B1 or B2 work, and the snow removing box has the alternating current 220V power supply, through rectification, supplies relay Z1 and transistor work after the filtering.

Snow removing box structure such as Fig. 3, collection snow groove 1 is arranged on it, in the collection snow groove 1 snow melting electrothermal tube resistance R 3 and contact K1 are arranged, snow falls, dissolve into water, turning circuit, contact K1 conducting is arranged, the work of Z1 relay is arranged, start blower fan B1 or B2, by transistor, relay, rectifier, resistance, electric capacity etc. constitute control circuit board 3, in the snow removing box control circuit board 3 is arranged, blower fan B1 or B2 also are provided with opening---blowing mouth 2, and its direction aims at the branch of track switch, close the position, there is high wind to blow, snowflake flies away, can not accumulated snow, freeze, can not influence the railway switch branch, close, snowing can not lead to a disaster yet.
