The specific embodiment
As shown in Figure 1 and Figure 2, a kind of point machine comprises locking iron 1, throw rod group 2, driving group 3, test set 4 (left test set 41, right test set 42), switch circuit controller 5 (left switch circuit controller 51, right switch circuit controller 52), indication rod group 6, casing 7; Throw rod group 2 has at least a termination to expose casing 7, for connecting point tongue or movable point frogs; Throw rod group 2 comprises throw rod 21, lock dog frame 22, lock dog 23, actuating sleeve 24; In the middle of lock dog frame 22, have fluting, fluting direction is for being communicated with the direction of locking iron 1 and throw rod 21; Indication rod group 6 and throw rod 21 are arranged in parallel through casing 7, and indication rod group 6 exposes termination and throw rod 21 and exposes termination and be positioned at casing 7 homonymies; Indication rod group 6 is provided with breach, left test set 41 and right test set 42 in the corresponding test set 4 of difference, when breach moves to corresponding left test set 41 or right test set 42, left test set 41 or right test set 42 just can enter the gap position of indication rod group 6, otherwise the part of left test set 41 or right test set 42 is expressed bar group 6 and blocks, and can not move and put in place; The left switch circuit controller 51 of corresponding switch circuit controller 5 or the array configuration that right switch circuit controller 52 contact groups switch on and off are made demonstration to this.
Driving group 3 be arranged in throw rod group 2 above or below, both length directions are parallel, for drive actions bar group 2 output movements and power.
Lock dog 23 is installed in the medial launder of lock dog frame 22, lock dog frame 22 is connected by bearing pin with lock dog 23, lock dog 23 can rotate around bearing pin in lock dog frame 22 grooves, when lock dog 23 moves to locking iron 1 termination, lock dog 23 rotates, coordinate with locking iron 1 termination circular arc, make oppositely displacement of throw rod 21, point machine is realized locking.
Actuating sleeve 24 clampings or be socketed on throw rod 21, lock dog frame 22 is " U " type structure, and lock dog frame 22 is connected to form neutral with throw rod 21, and actuating sleeve 24 is positioned at lock dog frame 22 and the neutral that throw rod 21 forms, and can in this neutral shift range, slide; When actuating sleeve 24 moves, can make lock dog 23 promote lock dog frame 22 by bearing pin, and then pushing action bar assembly 2 move or make lock dog 23 rotations enter locking/unlocked position.The reciprocating part of driving group 3 snaps in actuating sleeve 24 or is fastenedly connected with actuating sleeve 24 or the traverse of leaving a blank is connected.Driving group 3 drives actuating sleeve 24 crank motions.
Throw rod group 2 is provided with lock dog 23, and a side and the locking iron 1 of lock dog 23 are close to.
Locking iron 1 and throw rod group 2 are arranged in parallel.Locking iron can squeeze type for 1 minute and can not squeeze type.Can squeeze type locking iron 1 and be fixed in casing 7 by elastic element, when what locking iron 1 was subject to, squeeze de-power while being greater than setting value, there is enough elastic deformations in elastic element, and locking iron 1 is subjected to displacement squeezing under de-power effect, and the locking of point machine lost efficacy.Can squeeze in type locking iron 1 fixed sturcture and be provided with shift detector, detect in real time the displacement situation of locking iron 1, when the displacement of locking iron 1 surpasses setting value, the contact that shift detector is connected disconnects simultaneously.Can not squeeze type locking iron 1 and be directly fixed in casing 7, shift detector is not set in its fixed sturcture.
Left test set 41 is arranged in the position that throw rod group 2 is stretched out end of a period, and right test set 42 is arranged in throw rod group 2 and draws in the position that motion ends; Left test set 41 and right test set 42 can the whole direction along moving perpendicular to throw rod 21 be slided; In action of the spring bottom left test set 41, right test set 42, contact with throw rod 21 or actuating sleeve 24; Left test set 41 and left switch circuit controller 51 coordinate, right test set 42 and right switch circuit controller 52 coordinate, according to the position of the position of actuating sleeve 24 and indication rod group 6, make switch circuit controller 5 connect different contact groups, and then the various combination of the contact group simultaneously switching on and off by left switch circuit controller 51 and right switch circuit controller 52 represent the residing different conditions of switch machine.
Direction in below describing is all viewed as benchmark with vertical facing view.
In Fig. 1, lock dog 23 coordinates with locking iron 1 termination, and actuating sleeve 24 stops lock dog 23 to rotate counterclockwise.Lock dog 23 can not upward movement like this, and then throw rod group 2 can not upward movement, is blocked in this position.Now the driven cover 24 of left test set 41 promotes Compress Spring, and integral body moves right and puts in place, and the rotating shaft of corresponding left switch circuit controller 51 loses support, and under the effect of its spring, offside contact has been connected in contact conversion.
In Fig. 3, throw rod 21 has moved to intermediateness.From Fig. 1 state, actuating sleeve 24 drives upward movement for driven group 3, and first actuating sleeve 24 loses the restriction that lock dog 23 is rotated, and then promotes lock dog 23 rotation releases.Because lock dog 23 is blocked iron 1, stop, turned position is limited, and actuating sleeve 24 just promotes lock dog 23 upward movements, and then pushing action bar 21 upward movements.In actuating sleeve 24 upward movement processes, left test set 41 is to left movement under spring promotes, and then the rotating shaft that promotes left switch circuit controller 51 rotates, and disconnects the contact of having connected, until connect the contact of opposite side.This state, left test set 41 and right test set 42 all contact with throw rod 21.
In Fig. 4, throw rod 21 moves to another ultimate position and enters locking states.From Fig. 3 state, driving group 3 promotes actuating sleeve 24 and continues upward movement, until lock dog 23 moves to the another one termination of locking iron 1, supported by locking iron 1, lock dog 23 rotates counterclockwise under actuating sleeve 24 promotes, turn over after certain angle, actuating sleeve 24 continues upward movement can not clockwise rotate lock dog 23.Throw rod 21 is locked in another ultimate position.In actuating sleeve 24 upward movement processes, promote right test set 42 Compress Springs, integral body moves right.The rotating shaft of corresponding right switch circuit controller 52 loses support, and under the effect of its spring, contact conversion, disconnects original contact and connected offside contact.
