The acting rod is connected with a tip rail through a closely plastering adjusting rod, and the tooth back side of the rack bar is provided with an indication rod which is provided with a front indication rod, a rear indication rod and two inspection blocks. An automatic opening and closing device is arranged in a position corresponding to the two inspection blocks, and is provided with a transmission device and of an opening and closing device and an automatic opening and closing device. The utility model has the advantages of compact structure reliable indication. All top finger conforms to the requirement on relevant switch machines in a fifth chapter of Signal Maintenance Code of the ministry of railways.
Description
The utility model relates to other accessory equipments that are used for railway, relates in particular to the electronic switch machine automatic shutter of single phase A.C. fender guard.
The electronic switch machine of single phase A.C. divides can squeeze formula and the non-formula of squeezing.They have single-phase AC motor, and link to each other with retarder, hand-operated mechanism, friction clutch, slider successively, slider has tooth bar, tooth bar links to each other with throw rod through the triangle block, be provided with an isoceles triangle connected in star in the middle of the back of tooth of tooth bar, throw rod joins through adjustable switch operating rod and point tongue.Be positioned at the tooth bar left and right sides for squeezing formula electric switch machine throw rod, be positioned at tooth bar on one side for the non-electric switch machine throw rod that squeezes.At present the electric switch machine that adopts whether closely connected and signal to point tongue indicate examine and determine by the closely connected detector switch that is arranged on the rail both sides, and the connection loop control unit opens and closes its signal, and the structure qualification of loop control unit can not be carried out independent adjustment to location and antiposition, occurs empty expression sometimes and jumps the expression phenomenon.Poor reliability when use at closely connected master cock scene, and inconvenience is installed.
The purpose of this utility model provides a kind of compact conformation, the electronic switch machine automatic shutter of expression a kind of single phase A.C. of failure-free fender guard.
The utility model is taked following measures in order to achieve the above object, it comprises tooth bar, and be connected with throw rod by the triangle block, be provided with an isoceles triangle connected in star in the middle of the back of tooth of tooth bar, throw rod joins through adjustable switch operating rod and tongue, feature is that the back of tooth side of tooth bar is provided with indication rod, indication rod has preceding indication rod, back indication rod, two check piece, preceding indication rod anterior extension end is provided with the coupling head of joining with tongue, back indication rod rear stretching end is provided with the adjustment screw rod, the indication rod stage casing is provided with two and checks piece slip cavity, checks that two the piece corresponding section is provided with two automatic switch devices, and automatic switch device has switch circuit controller driving device and switch circuit controller.
The utility model has the advantages that: compact conformation, expression is reliable, and switch circuit controller is a full-closed structure, can shake with handgrip during power failure, the formula of can squeezing is arranged and non-ly squeeze two kinds of formulas, and every index meets the relevant switch machine of the 5th joint institute requirement in Ministry of Railways's " signal maintenance rule ".
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is an indication rod, switch circuit controller, switch circuit controller driving device and slider rack structure scheme drawing;
Fig. 2 is an indication rod structure side view;
Fig. 3 is the indication rod structural representation;
Fig. 4 is a switch circuit controller transmission structures scheme drawing.
The electronic switch machine automatic shutter of single phase A.C. fender guard comprises tooth bar 2; and be connected with throw rod by the triangle block; be provided with an isoceles triangle connected in star in the middle of the back of tooth of tooth bar; throw rod joins through adjustable switch operating rod and tongue; feature is that the back of tooth side of tooth bar is provided with indication rod 1, and indication rod has preceding indication rod 5, back indication rod 7, two is checked piece 9.Preceding indication rod anterior extension end is provided with the coupling head 6 of joining with tongue, back indication rod rear stretching end is provided with adjusts screw rod 8, the indication rod stage casing is provided with two and checks piece slip cavity, check that two the piece corresponding section is provided with two automatic switch devices, automatic switch device has switch circuit controller driving device 3 and switch circuit controller 4.The switch circuit controller driving device has the post of inspection cliding seat 11, on inspection post cliding seat, be connected with spring perch 12, check to be provided with in the post cliding seat and check post 16, check that post one end top is provided with tooth bar contact slide head 17, and vertically be provided with and check 10, check that the post other end is provided with to check the capital bar, check that the capital bar is provided with spring 16 outward, check that the capital bar passes spring seat end cover and joins with checking capital head 14, check that capital head corresponding section is provided with switch circuit controller rocking arm 13.Switch circuit controller is provided with the switching contact and the indication rod contact of electrical motor.Spacing between the indication rod two inspection heads is diverged to journey (mm) for the 215+3-road.
Installation method of the present utility model is:
1. before installing, adjust two in the product indication rod earlier and check piece breach distance.Should unclamp the cross bolts on the indication rod during adjustment earlier, turn the adjustment screw rod of its tail end again.The actual journey (L millimeter) of opening according to point tongue is pressed X=215+3-L formula calculating adjustment breach distance
2. when debugging, at first shake hand crank, the throw rod and the indication rod of product remained on extended position.Regulate the adjustable switch operating rod on the tongue, make tongue and stock rail closely connected; Regulate the connecting rod for indication on the tongue again, make and stretch out inspection head on a side the inspection post near indication rod and fall into and check the piece breach, and reach 1.5 ± 0.5 millimeters sideshake requirement.But must check simultaneously, thick iron plate sandwiches between tongue and the stock rail with 4mm at tongue head rod place, and at this moment throw rod is not at locking states, and the inspection head should not fall into checks the piece breach.
3. then, utilize hand crank that throw rod and indication rod are shaken into switch machine, regulate adjustable switch operating rod again, make tongue and stock rail closely connected.At last, the adjustment screw rod that turns the indication rod tail end satisfies till the above-mentioned same requirement the opposing party's inspection post and locking relation, tightens cross bolts again.
