Abstract
The utility model relates to a rail speed increasing turnout moveable locking hook, which belongs to the rail turnout technique field, mainly solving the problem that: a connecting clearance is arranged between the tip rail connecting head iron of the rail speed increasing turnout locking hook with moveable core and the locking hook concave groove, which causes that: the requirement of not needing closing for the clearance turnout of 4mm between the tip rail and the basal rail can not be ensured. The utility model is characterized in that: the utility model comprises two locking hook heads of left and right. The upper part of the hook body of the locking hook is provided with a rectangle concaved groove, and the bottom is a plane. The left and right locking hook heads are respectively connected with the locking through the connecting shaft in a rotary and moveable manner. The utility model can not be locked when the clearance between the tip rail and the basal rail is bigger or equal to 4 mm, and the utility model can directly displace the original integrated locking hook, and cooperated with the original turnout locking mechanism, and the utility model is mainly used for the rail speed increasing turnout rail locking mechanism with the moveable core.
Description
Technical field
The utility model relates to a kind of railway switch locking hook, the movable locking hook that particularly a kind of suitable railway speed increase track switch movable point frogs uses.Belong to the railway switch technical field.
Background technology
Railway " signal maintenance rule " regulation, when having 4 millimeters and above gap between point tongue and the stock rail, track switch must not locking.Existing movable point frogs acclerating road switch locking hook is a monolithic construction, and left and right two ends are locking hook gib head, and middle locking hook coupler body is provided with the groove that cooperates with the tongue connecting iron, is arcwall face below.In the track switch transfer process, the locking hook must integral body shake to reach the purpose of locking point tongue.Its weak point is owing to must joint gap be arranged design between tongue connecting iron and the locking hook groove, the strength deficiency of tongue in addition, must cause when 4 millimeters of existence between tongue and the stock rail or the obstruction more than it, the track switch locking that can also do as usual makes between tongue and the stock rail requirement that 4 millimeters gap track switches must not locking guarantee.
Summary of the invention
It is a kind of when having 4 millimeters and above gap between tongue and the stock rail that the purpose of this utility model is exactly to provide at above-mentioned weak point, the railway speed increase track switch activity locking hook that track switch can not locking.
Technical solution of the present utility model is: the movable locking hook of a kind of railway speed increase track switch, comprise left and right two locking hook gib heads, and it is characterized in that: the top of locking hook coupler body has rectangular recess, and the bottom surface is the plane; Left and right locking hook gib head flexibly connects rotationally through connecting axle and locking hook coupler body respectively.
Locking hook coupler body described in the utility model technical solution can be the U sections.
Can have groove on the bottom surface of the locking hook coupler body described in the utility model technical solution, be provided with the oil storage felt in the groove.
Groove described in the utility model technical solution can be two strip deep trouths, is symmetrically distributed on the bottom surface of locking hook coupler body and arranged on left and right sides; Groove has been embedded in the oil storage felt.
The utility model is owing to adopt a left side, right locking hook gib head and locking hook coupler body three parts are formed, an and left side, right locking hook gib head is connected with locking hook coupler body by connecting axle, locking hook coupler body top is rectangular recess, the bottom surface is the plane, thereby, not only eliminated free gap between tongue connecting iron and locking hook groove, and when track switch is changed, locking hook coupler body just slides on the locking bar plane, and no longer shake, by a left side, right two locking hook gib heads move up and down the locking point tongue, have so just increased the bonding strength of tongue, have solved the problem of 4 millimeters gap lockings between movable point frogs acclerating road switch tongue and the stock rail effectively.The utility model is owing to be provided with groove in locking hook coupler body bottom surface, and is provided with the oil storage felt in groove, thus can reduce greatly its with the locking bar plane between frictional force, the locking hook is moved more accurately and reliably.The utlity model has when the gap is more than or equal to 4 millimeters between tongue and the stock rail can not locking, can directly replace the matching used characteristics of original monolithic locking hook and original switch locking mechanism.The utility model is mainly used in railway speed increase track switch movable point frogs locking mechanism.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the plan structure schematic diagram of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2.Locking hook coupler body 1 is the U sections, has rectangular recess on it, and the bottom surface is the plane.Be tight fit between groove and the tongue connecting iron.Be provided with the groove of symmetry in locking hook coupler body 1 bottom surface and arranged on left and right sides, it has been embedded in oil storage felt 8, to reduce the planar friction between itself and the locking bar.Also can on other position, bottom surface, be provided with groove, be provided with the oil storage felt in it.Left and right lock hook gib head 2,3 is identical with existing monolithic locking hook gib head, and its inner is fixed on the locking hook coupler body 1 through connecting axle 4 respectively, and connecting axle 4 outer ends are provided with back-up ring 5, locking nut 6 and cottor pin 7.When track switch was changed, locking hook coupler body 1 just slided on the locking bar plane, and left and right locking hook gib head 2,3 rotates around connecting axle 4 respectively, moves up and down the locking point tongue.
