Abstract
The utility model discloses an automatic guardrail device for railroad accommodation crossings, which is composed of a mobile guardrail, a motor, pressure sensors and an electrical control box, wherein the mobile guardrail is arranged on the accommodation crossings at both sides of a railroad; the pressure sensors are arranged under rail bearings of a rail and are connected with the electrical control box; both ends of a travel track of the mobile guardrail are respectively provided with a travel switch which is connected with the electrical control box through cables; the motor which drives rolling wheels of the mobile guardrail to rotate is connected with the output end of control signals of the electrical control box. The utility model can automatically control the railroad accommodation crossings to open and close, and thus the use can be convenient and the accidents in safety due to man-made factors can be avoided; the utility model has the advantages of convenient use, high safety, simple structure and low cost.
Description
Technical field:
The utility model relates to a kind of automatic guard bar device of the safety device that is used for railway crossing, particularly a kind of railway crossing, belongs to the technical field of railway security protective equipment.
Background technology:
At present, in railway transportation,, generally all be provided with room, road junction and guard bar device, in the room, road junction, be provided with electric control box, be used for controlling opening or closing of guard bar device at railway crossing in order to guarantee vehicle and the pedestrian safety by railway crossing the time; The room, road junction is on duty by the people, before train arrives, closes level crossing by the manual handling guard bar device.Because artificial and other factors can not in time be closed the tragedy that level crossing will lead to car crash sometimes.
Summary of the invention:
The purpose of this utility model is: but a kind of open and close of automatic guidance guard bar device is provided, and the automatic guard bar device of the railway crossing that safety is good and simple in structure, cost is low, easy to use is to solve the problem that prior art exists.
The utility model is to constitute like this: it is by portable guardrail (1), motor (7), pressure sensor (5), electric control box (4) constitutes, portable guardrail (1) is contained in respectively on the level crossing (2) of being located at the railway both sides, the sleeper (6) that pressure sensor (5) is contained in rail links to each other with electric control box (4) in being installed in room, road junction (3) down and by cable, walking track two ends at portable guardrail (1) are provided with travel switch, travel switch links to each other with electric control box (4) by cable, and the motor (7) that drives the rotation of portable guardrail (1) roller links to each other by the control signal output ends of cable with electric control box (4).
Pressure sensor (5) is contained in and is positioned at level crossing (2) the right and left and respectively under the rail sleeper (6) apart from level crossing (2) 500～2000m.
The utility model is provided with pressure sensor under the rail sleeper of distance railway crossing certain distance, when train vibration influence is above pressure sensor, in the pressure sensor of the transmission of pressure that train produces under the sleeper, pressure sensor is converted to electric signal with the train pressure that perceives, be sent to electric control box in the room, road junction by cable, electric control box sends actuation signal, and guardrail starts, close the road junction, stop vehicle and pedestrian to pass through.When train by the road junction, when driving to the sensor of opposite side, control box sends reset signal, the road junction guardrail resets, and allows vehicle and pedestrian to pass through, thereby has guaranteed vehicle and pedestrian's safety.
Therefore, compared with prior art, the utility model is by setting pressure sensor under the rail sleeper, but the open and close of automatic guidance level crossing, safety misadventure easy to use and avoided human element to cause, have the good advantage of property easy to use, safe, and it is simple in structure, cost is low, on existing road junction, does transformation slightly and get final product.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is an electrical schematic diagram of the present utility model.
The specific embodiment:
Circuit of the present utility model is rotating control; its fender guard adopts thermal relay FR protection; its electric control theory is as follows: as shown in Figure 2; when train forward process pressure sensor (5), when travel switch SQ2 did not put in place, the closed motor (7) of also controlling of contactless switch KM1 started; start portable guardrail (1); travel switch SQ2 disconnected after portable guardrail (1) put in place, and contactless switch KM1 disconnection also control motor (7) stops, and closes the road junction.When train passes through the pressure sensor (5) of the other end, travel switch SQ1 does not put in place, contactless switch KM2 closure is also controlled motor (7) startup, start portable guardrail (1), travel switch SQ1 disconnected after portable guardrail (1) put in place, contactless switch KM2 disconnects and control motor (7) stops, and opens the road junction; When train reverse driving process pressure sensor (5), when travel switch SQ2 did not put in place, the closed motor (7) of also controlling of contactless switch KM2 started, start portable guardrail (1), travel switch SQ2 disconnected after portable guardrail (1) put in place, and contactless switch KM2 disconnects, motor (7) stops, and closes the road junction.When train passes through the pressure sensor (5) of the other end, when travel switch SQ1 does not put in place, contactless switch KM1 closure is also controlled motor (7) startup, start portable guardrail (1), travel switch SQ1 disconnected after portable guardrail (1) put in place, contactless switch KM1 disconnects, and control motor (7) stops, and opens the road junction.In order to guarantee the reliability of power supply, can adopt dual power supply or be equipped with emergency power supply unit.
Claims (2)
1. the automatic guard bar device of a railway crossing, it is by portable guardrail (1), motor (7), pressure sensor (5), electric control box (4) constitutes, it is characterized in that: portable guardrail (1) is contained in respectively on the level crossing (2) of being located at the railway both sides, the sleeper (6) that pressure sensor (5) is contained in rail links to each other with electric control box (4) in being installed in room, road junction (3) down and by cable, walking track two ends at portable guardrail (1) are provided with travel switch, travel switch links to each other with electric control box (4) by cable, and the motor (7) that drives the rotation of portable guardrail (1) roller links to each other by the control signal output ends of cable with electric control box (4).
2. the automatic guard bar device of railway crossing according to claim 1 is characterized in that: pressure sensor (5) is contained in and is positioned at level crossing (2) the right and left and respectively under the rail sleeper (6) apart from level crossing (2) 500～2000m.
