Above-mentioned structure, when train enters the induction range of the inductor that is arranged on the railway both sides, inductor sends approach signal, accessory drive made cross bar be rotated down around the vertical rod pin jointed end to start autoalarm simultaneously when control setup received this approach signal, cross bar is subjected to the position limiting structure qualification when rotating hard-over stops to be rotated further, this timed unit accessory drive stops, finish interception, when the inductor induction range is left in the train long journey, inductor sends away from signal, control driving device controls cross bar upwards rotated and cuts out autoalarm simultaneously when control setup received this away from signal, stopped when cross bar turns to minimum angle of rotation timed unit accessory drive, and blocker recovers original state, simple in structure, control does not need the special messenger to keep an eye on safe and convenient easily.
Description of drawings
Fig. 1 is the plan structure scheme drawing of the utility model specific embodiment.
Fig. 2 is the utility model specific embodiment structural representation.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As Fig. 1, shown in Figure 2, road and rail of the present utility model turnout auto alarm blocker, comprise the blocking apparatus 41 that is arranged on railway 21 and 31 liang of forks of highway, be arranged on the inductor 51 on railway side highway both sides, 61 and blocking apparatus 42, be arranged on the inductor 52 on railway side highway both sides, 62, described blocking apparatus is by vertical rod 1 and the hinged cross bar 2 that is arranged on described vertical rod middle part of an end, actuating device described in this specific embodiment is a motor 4, warning device 12 and control setup 13 constitute, described vertical rod is provided with and limits the position limiting structure that described cross bar is rotated down, and the described actuating device of signal control that described control setup receives by inductor drives described cross bar rotation and warning device work.
Described vertical rod is provided with and limits the position limiting structure 7 that described cross bar is rotated down, described vertical rod top is provided with pulley 6, described pulley is provided with tension rope 3 (being steel rope in the present embodiment), described tension rope one end is arranged on the cross bar other end, the tension rope other end is arranged on the cylinder 5, described cylinder connects motor, described motor positive and inverse of signal control and warning device work that described control setup receives by inductor by transmission decelerating device 11.
Above-mentioned structure, when train enters the induction range of the inductor that is arranged on the railway both sides, inductor sends approach signal, the control motor was just changeing and cross bar is rotated down around the vertical rod pin jointed end start autoalarm simultaneously under the deadweight effect when control setup received this approach signal, warning device herein is alarm bell or siren, rotative speed is by controlling with motor bonded assembly tension rope linear speed, herein with rotating speed of motor and to twine the diameter of cylinder of tension rope relevant, cross bar is subjected to the position limiting structure qualification when rotating hard-over stops to be rotated further, this timed unit control motor stops operating, finish interception, when the inductor induction range is left in the train long journey, inductor sends away from signal, the counter-rotating of control motor was upwards rotated tension rope tractive cross bar and is closed autoalarm simultaneously when control setup received this away from signal, when turning to minimum angle of rotation timed unit control motor, cross bar stops operating, blocker recovers original state, simple in structure, control easily, do not need the special messenger to keep an eye on safe and convenient.
