Embodiment 1
Pantagraph current collector is device subway train being responsible for obtain to subway train from contact rail electric current.Frame installation, in On Bearing Cantilever of Motor In Subway Train side, carries out up-down adjustment by the sawtooth at back to pantagraph current collector.A kind of subway train pantagraph current collector, as Figure 1-5, resilient sleeve 1 is connected on framework 2 by fastener, insulcrete 3 side connects carbon slipper 4, side linking springs position-limited rack 5, the both sides of insulcrete 3 are provided with Weak link groove 6, insulcrete 3 is made up of insulating material, non-conducting electric current, the width of Weak link groove 6 place insulcrete is less than all the other places, when due to unforeseen circumstances, when carbon slipper 4 bumps against on external object, insulcrete 3 can rupture from Weak link groove 6, thus ensure that pantagraph current collector main body is injury-free, first spring 7 and the second spring 8 are supported by spring retainer 9, and be connected on framework 2 by a main shaft 12, framework 2 is provided with spring retainer bar 10, can carry out spacing to spring, depression bar 11 one end and main shaft 12 are rotationally connected, the other end is connected with U-shaped frame 14 by latch 13, U-shaped frame 14 is connected by screw threads for fastening with ejecting rod of cylinder 15, when carbon slipper 4 is thrown off with contact rail by needs, ventilate to cylinder 16, cylinder 16 push rod stretches out, oppress insulcrete by depression bar 11 to rotate, thus drive carbon slipper 4 to move downward, carbon slipper 4 is made to be separated from contact rail, ejecting rod of cylinder 15 is connected with cylinder 16, U-lag connecting panel 21 one end with circular hole is connected with carbon slipper 4 by fastener, one end with U-lag is connected by fastener with transition connecting plate 22, transition connecting plate 22 is connecting insulator 23 above, bottom connecting cable terminal 24.Because insulator 23 and insulcrete 3 are made by insulating material, therefore whole pantagraph current collector is except cable and terminal, transition connecting plate 22, U-lag connecting panel 21, carbon slipper 4 and connect except the fastener of these parts, agent structure is not charged, insulating effect is played to train's body, make bogie truck not charged, prevent the generation of electric shock casualty accident.When due to unforeseen circumstances, when carbon slipper 4 bumps against on external object, insulcrete ruptures from Weak link groove 6, breaks together with U-lag connecting panel 21, thus protection pantagraph current collector entirety is without prejudice, and remaining pantagraph current collector main body is not charged, is convenient to maintenance operation.Framework is provided with protective cover, there is the effects such as attractive in appearance, dust-proof, antifouling, anti-splashing, the effect of protection pantagraph current collector main body.
Described resilient sleeve 1 is divided into overcoat 17, elastic element 18 and inner sleeve 19, described overcoat 17 has the hole 20 connected for fastener above, it is elastic element 18 between overcoat 17 and inner sleeve 19, elastic element 18 is for having elastomeric bar-shaped or schistose texture, the angle of cylinder 16 can be made to twist, and the vibration to cylinder 16 can be reduced.
Described cylinder 16 side has the structure matched with inner sleeve 19, can support cylinder.
Described insulcrete 3 be all fastened by bolts part between carbon slipper 4 and spring retainer frame 5 and be connected.
The change in location of carbon piston shoes 25 controls the mode of operation of device of the present utility model, as shown in Figure 6, carbon piston shoes 25 are now subject to the effect of the first spring and the second spring, be in off-position, namely stop bit is in, carbon piston shoes 25 upper surface is higher than contact rail 26 lower surface, and now not yet enter mode of operation for pantagraph current collector, now ejecting rod of cylinder does not stretch out.As shown in Figure 7, carbon piston shoes 25 are now subject to the compressing of contact rail 26, under the effect of the first spring and the second spring, and carbon piston shoes 25 upper surface and contact rail 26 lower surface close contact, pantagraph current collector obtains electric current from contact rail 26, and now pantagraph current collector is in running order.As shown in Figure 8, maintenance, station or some urgent when, need carbon piston shoes 25 and contact rail 26 to depart from, the carbon slipper 4 of pantagraph current collector is not with a little, now, to cylinder ventilation, ejecting rod of cylinder extends, compressing insulcrete moves downward, carbon slipper and contact rail 26 are departed from, and after cylinder venting, carbon piston shoes are got back to as Fig. 6 or position as shown in Figure 7 under the effect of the first spring and the second spring.
The above embodiment only have expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
