Detailed description of the invention
Embodiment 1
A kind of personnel's automatic safety device for railcar as shown in Figure 1, comprises the tray supporter 9 be fixed on car body, and tray supporter 9 is hinged with the rear end of protection tray 6; The front end of protection tray 6 is connected with and hooks tongue 7 and reset rope 11; Reset rope 11 is connected with the reset rope handle 10 be in car body; Protection tray 6 is flexibly connected with hook tongue 7; Protection tray 6 front end be provided with hook that tongue 7 coordinates take hook 13.Hook tongue 7 and be connected with gangbar 4; Gangbar 4 front end is connected with feeler lever 1, and feeler lever 1 is connected on car body by elastic recovery device.Tray supporter spring 8 is provided with between tray supporter 9 and protection tray 6.
Protection tray 6 is provided with the groove 16 coordinated with underground railway track, when this design makes protection tray 6 fall, just in time falls into interorbital, and reduces protection tray 6 and the distance on ground, is more convenient for holding up human body.
As shown in Figure 2, gangbar 4 is connected with feeler lever 1 by feeler lever support 2.Gangbar 4 is hinged with the middle part of feeler lever support 2; Feeler lever 1 is connected with the bottom of feeler lever support 2, is provided with gangbar retracing spring 3 between the top of feeler lever support 2 and gangbar 4.For preventing gangbar 4 to be fixedly connected with feeler lever 1, make lack buffering and be easy to damage.When gangbar retracing spring 3 is for producing deformation because being hit between gangbar 4 and feeler lever 1, gangbar 4 is resetted.
Elastic recovery device is be fixed on brace on car body by torque spring or feeler lever 1 can be connected on car body and feeler lever 1 can be made to drive gangbar 4 to produce the device of displacement as elastic force bar etc. by other.
Reset rope 11 is steel rope, also can be other material as the rope such as carbon fiber, polyethylene body.
As shown in Figure 4, said apparatus is in subway circulation process, and when feeler lever 1 touches band human body, the impact being subject to human body drives feeler lever 1 to move, and feeler lever 1 drives gangbar 4 motion that hook tongue 7 is separated with protection tray 6.The front end of protection tray 6 drops to after losing the support hooking tongue 7 on the rail before wheel, and rear end is connected on tray supporter 9, thus has angle with track, makes human body drop on protection tray 6, avoids human body to be rolled by wheel and damages.Wherein, protection tray 6, for after hooking tongue 7 and being separated with protection tray 6, is pulled on track by tray supporter spring 8 fast.
As shown in Figure 5, when said apparatus is finished using, when needing to reset, by resetting, rope handle 10 pulls reset rope 11, drives protection tray 6 to reset.
Above-mentioned forward and backward direction of advancing for relative headstock is front, after what headstock was advanced be reversed.
Embodiment 2
As shown in figs. 1 and 3, carrying out urgent triggering initiatively for realizing driver when finding emergency situation, following setting is carried out on the basis of embodiment 1: gangbar 4 rear end is provided with anchor fitting 14, and anchor fitting 14 is provided with bearing pin 15; Hooking tongue 7 rotation is fixed on bearing pin 15; Described hook tongue 7 comprises hook body and STATEMENT OF FEDERALLY SPONSORED 71; Hook body upper part and be provided with block 72, hook body lower part and be provided with hook body 73, in the middle part of hooking body, bending and forming has obstruction portion 74; STATEMENT OF FEDERALLY SPONSORED 71 upper end is connected with gangbar 4; STATEMENT OF FEDERALLY SPONSORED 71 lower end is provided with the linkage portion 75 coordinated with obstruction portion 74 activity; Bearing pin 15 is through hooking in the middle part of body and STATEMENT OF FEDERALLY SPONSORED 71; Block 72 front is provided with lance 12, and lance 12 is connected with electromagnetic valve 5; Electromagnetic valve 5 is connected with the control system in car body.The connection mode of STATEMENT OF FEDERALLY SPONSORED 71 upper end and gangbar 4 is preferably hinged, prevents from like this lacking buffering between two parts and being easy to damage.
When needs initiatively promptly trigger, control lance 12 by electromagnetic valve 5 and clash into block 72, drive hook body 73 to depart from protection tray 6.
When driver does not find emergency situation, when device triggers automatically, feeler lever 1 drives gangbar 4 and STATEMENT OF FEDERALLY SPONSORED 71, and STATEMENT OF FEDERALLY SPONSORED 71 makes hook body 73 and protection tray 6 depart from by obstruction portion 74 and linkage portion 75.
The explanation of above example just understands core concept of the present utility model for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
