Abstract

The utility model relates to a narrow track fork opening and closing as well as tightness automatic prompt device. A switching machine is used for adjusting the distance between a copper pipe and magnetic steel so as to control a normally open contact of a reed pipe to be opened and closed; the opening and the closing of a normally open contact and a normally closed contact of a DC relay can be controlled by the opening and the closing of a junction point inside the reed pipe; the opening and the closing of the normally open contact and the normally closed contact of the DC relay are respectively used for controlling a red LED and a green LED to alternately give out light, so that whether downhole operating personnel can operate locomotives or mining cars to pass through a deviation hole or a fork can be prompted. The device has the characteristics of simple structure, low production cost, convenient operation and use as well as visualized and accurate control.

Description

Narrow gauge track diverges to and closes and the tightness automatic prompting device

Technical field

The utility model relates to a kind of narrow gauge track is diverged to and closes and device that tightness is pointed out.

Background technology

On the rail transport circuit of colliery, a plurality of steps or fork are arranged all, whether locomotive, mine car can be carried out artificial stay cord by step or fork and list or indicator lamp is set, because field operation personnel maloperation track switch, and the electric locomotive driver thinks that track switch is closed or tight by mistake, shipping accident such as cause locomotive string trouble bump tunnel, air door or slide down, this is the maximum hidden danger of colliery shipping accident, promotes in the shipping accident in the colliery and accounts for great ratio.

Summary of the invention

Problem at above existence, the utility model provides a kind of narrow gauge track to diverge to and has closed and the tightness automatic prompting device, switching by track switch and tightness automatic guidance red, green light, and by red, green light indication locomotive, mine car step or the fork by main transport roadway whether.

For achieving the above object, technical solution adopted in the utility model is: this device comprises the copper pipe that is fixed on the track switch switch blade, be fixed on the track switch stock rail and position and the corresponding magnet steel of copper pipe, the switch that simple turnout is opened and closed and by DC relay, red light emitting diodes, the electric part of green light-emitting diode and the dry-reed tube composition of being located at copper pipe, folding by open contact in the distance control dry-reed tube between switch adjustment copper pipe and the magnet steel, the folding of open contact and normally closed contact in the folding control DC relay of dry-reed tube inner contact, red light emitting diodes is controlled in the open contact of DC relay and the folding of normally closed contact respectively and green LED is alternately luminous.

This device is suspended on red light on the tunnel when bright by control, point out main lane of traffic locomotive, mine car forbid by, mine car can pass through on the lane of traffic, when the control green light is bright, point out locomotive on the main lane of traffic, mine car to pass through, by the operation switching of track switch and the tightness of track switch, reminded electric locomotive driver or other operating personnels when on the main lane of traffic locomotive, mine car can pass through, when prop up locomotive on the lane of traffic, mine car can pass through.The utlity model has simple in structurely, productive costs is low, and is easy for operation, controls visual and accurate characteristics.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is schematic circuit diagram of the present utility model;

Fig. 3 is the circuit diagram of the utility model control red light emitting diodes;

Fig. 4 is the circuit diagram of the utility model control green LED.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described:

As shown in Figure 1, the copper pipe 1 usefulness iron clamp that dry-reed tube is housed is fixed on the track switch switch blade, on the track switch stock rail and with copper pipe 1 opposite position with the fixing magnet steel 2 of sealant, switch 3 is contained in track switch switch blade one end, can carry out open and close to simple turnout.

As Fig. 2, Fig. 3 and shown in Figure 4, the circuit part of this device comprises dry-reed tube, DC relay, red light emitting diodes and green light-emitting diode, for DC relay provides direct supply, while 127V alternating current is respectively red light emitting diodes and green light-emitting diode provides power supply after the 127V alternating current process transformation.

When operation switch 3 makes simple turnout closed, magnet steel 2 is with the dry-reed tube distance during greater than 15mm, at this moment the open contact K1 in the dry-reed tube breaks away from magnet steel magnetic and often opens, this moment, DC relay coil KC did not have, relay magnet discharges, the a pair of open contact KC1 of control red light emitting diodes disconnects, cut off red light emitting diodes 127v power supply, red light is extinguished, a pair of normally closed some KC2 closure of while DC relay, connect the 127v power supply of green LED, make green light bright, but locomotive, mine car safe passing on this moment main lane of traffic.

When operation switch 3 simple turnouts are opened, when magnet steel 2 reaches 10mm with the dry-reed tube distance, open contact K1 in the dry-reed tube is subjected to magnet steel magnetic force closure, DC relay coil KC has electric adhesive, and relay normally open point KC1 closure makes red light bright, normally closed some KC2 disconnects, green light is gone out, and at this moment trunk main forbids locomotive, mine car to pass through, but the step mine car can pass through.

Claims

1, a kind of narrow gauge track diverges to and closes and the tightness automatic prompting device, comprise the copper pipe (1) that is fixed on the track switch switch blade, be fixed on the track switch stock rail and position and the corresponding magnet steel of copper pipe (1) (2), the switch (3) that simple turnout is opened and closed and by DC relay, red light emitting diodes, the electric part of green light-emitting diode and the dry-reed tube composition of being located at copper pipe (1), it is characterized in that: adjust the folding of the interior open contact of distance control dry-reed tube between copper pipe (1) and the magnet steel (2) by switch (3), the folding of open contact and normally closed contact in the folding control DC relay of dry-reed tube inner contact, red light emitting diodes is controlled in the open contact of DC relay and the folding of normally closed contact respectively and green LED is alternately luminous.
