Abstract
A kind of height-limiting frame and pedestrian overcrossing alarm protecting apparatus, this device comprises the first conducting strip, iron block, extension spring, height-limiting bar, column, torsionspring, container, electromagnet, the second conducting strip, switch, loudspeaker and warning lamp; The beneficial effects of the utility model: arrange automatic alarm system at the safe distance of distance height-limiting frame or pedestrian overcrossing 50-100 rice, when automobile superelevation travels, when driver hears horn blast and sees that warning lamp glimmers, there is the sufficiently long time to take safety measures and avoid accident to occur.The utility model avoids the various control module design of complicated high cost, and structure is simple, reasonable in design, cost is low, easy to install, has good value for applications.After autoalarm triggers, the while of horn blast, the warning lamp in front glimmers, and reminds driver and pedestrian in time, avoids contingency, ensures the security of the lives and property.
Description
Technical field
The utility model belongs to transit equipment technical field, particularly relates to a kind of height-limiting frame and pedestrian overcrossing alarm protecting apparatus.
Background technology
Current many roads are provided with height-limiting frame for preventing automobile superelevation, road wider, the road of stream of people's comparatively dense is also provided with pedestrian overcrossing.Due to some automobile height-limiting frames or pedestrian overcrossing arrange lower, can accidents be there is when driver travels with sensation sometimes, if bump against pedestrian overcrossing, destroy and more seriously even can cause casualties.
What more existing height-limiting frames or pedestrian overcrossing had does not mark eye-catching height nameplate, in addition when automobile loading is higher or forget unload travel from dump bucket time, driver often judge inaccurate or careless and inadvertent and occur with height-limiting frame, pedestrian overcrossing accidents.The existing device for height-limiting frame, the warning of pedestrian overcrossing superelevation traveling is also relatively less.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of height-limiting frame and pedestrian overcrossing alarm protecting apparatus.
The technical solution of the utility model is such: this device comprises the first conducting strip, iron block, extension spring, height-limiting bar, column, torsionspring, container, electromagnet, the second conducting strip, switch, loudspeaker and warning lamp, column fixes on the ground, height-limiting bar is connected with in the upper end of column, one end of height-limiting bar freely, the other end is at column axial restraint, can rotate around it, in the junction of height-limiting bar and column, torsionspring is installed.Height-limiting bar connects extension spring, connects iron block below extension spring, iron block is rigidly connected below by insulation materials and the first conducting strip.Connecting container on column, be provided with loudspeaker, electromagnet and two the second conducting strips in container, switch is also arranged on column.
Described apart from the height-limiting frame at movable height-limiting bar device 50-100 rice or pedestrian overcrossing, warning lamp is being installed.
The beneficial effects of the utility model:
(1) arrange automatic alarm system at the safe distance of distance height-limiting frame or pedestrian overcrossing 50-100 rice, when automobile superelevation travels, when driver hears horn blast and sees that warning lamp glimmers, have the sufficiently long time to take safety measures and avoid accident to occur.
(2) the utility model avoids the various control module design of complicated high cost, and structure is simple, reasonable in design, cost is low, easy to install, has good value for applications.
(3) after autoalarm triggering, the while of horn blast, the warning lamp in front glimmers, and prompting driver and pedestrian, avoid contingency in time, ensures the security of the lives and property.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model circuit theory diagrams;
In figure: 1 first conducting strip 2 iron block 3 extension spring 8 electromagnet 9 second conducting strip 10 switch 11 loudspeaker 12 warning lamp.
Detailed description of the invention
Below in conjunction with accompanying drawing and enforcement, the utility model is further described.
As shown in Figure 1, distance height-limiting frame or pedestrian overcrossing 50-100 rice are provided with movable height-limiting bar device, comprise 1 first conducting strip 2 iron block 3 extension spring 4 height-limiting bar 5 column 6 torsionspring 7 container 8 electromagnet 9 second conducting strip 10 switch 11 loudspeaker 12 warning lamp, column 5 fixes on the ground, height-limiting bar 4 is connected with in the upper end of column 5, one end of height-limiting bar 4 freely, the other end is at column 5 axial restraint, can rotate around it, at height-limiting bar 4 and the junction of column 5, torsionspring 6 is installed.Height-limiting bar connects extension spring 3, and extension spring 3 connects iron block 2 below, and iron block 2 is rigidly connected below by insulation materials and the first conducting strip 1.Connecting container 7 on column 5, be provided with loudspeaker 11, electromagnet 8 and two the second conducting strips 9 in container 7, switch 10 is also arranged on column 5.Apart from the height-limiting frame at movable height-limiting bar device 50-100 rice or pedestrian overcrossing, warning lamp 12 is being installed.
Line connection is as Fig. 2, and electromagnet 8, switch 10 and power supply U1 are connected into a circuit, and the first conducting strip 1, second conducting strip 9, loudspeaker 11, warning lamp 12 and power supply U2 are connected into second circuit.
operating principle and process
After external power supply U1, U2 connect, close switch 10, electromagnet is energized, and because distance iron block 2 is comparatively far away, therefore can not be attracted.When the automobile of superelevation is through out-of-date, collision height-limiting bar 4 makes it after column 5 turns an angle, iron block 2 by electromagnet 8 attract (note: automobile through after, height-limiting bar is returned to origin-location under the effect of torsionspring 6, the attraction of electromagnet 8 pairs of iron blocks is greater than the pulling force of extension spring 3, now iron block is still adsorbed on electromagnet), first conducting strip 1 contacts with the second conducting strip 9 and circuit B is connected, loudspeaker 11 are blown a whistle to report to the police and are positioned at the warning lamp 12 that height-limiting frame or pedestrian overcrossing are installed simultaneously and glimmer, alerting drivers and pedestrian.After potential safety hazard is got rid of, cut-off switch 10, electromagnet power-off, iron block 2 is withdrawn into initial position by spring 3, and in circuit B, the first conducting strip 1, second conducting strip 9 disconnects thereupon, reports to the police and terminates.Again close switch 10, enters working cycles next time.
