Abstract
The adjustable, insulating push or track rod for railway points has two sleeves (2) fitted together in the manner of a turnbuckle, each of which has an internal thread (1). Track or push-rod sections (8) are screwed into the internal thread (1) so that the rotation of the turnbuckle permits the axial adjustment of the track or push-rod. The sleeves (2) are interconnected via insulating intermediate layers (4) using at least one off-centre locating pin (5) or connecting bolt (6), thus making it possible to maintain the correct rotation position even in case of lengthy operation and vibrations.
Description
The present invention relates to the adjustable, insulating pusher or the tierod of rail track switch, there are two tapped sleeves its middle part, and pusher partly is screwed in the sleeve.
The a pair of tongue that German patent DE-PS 1 116 712 has proposed in the clamping plate type switch lock to adopt the insulation pusher turn-out track power to be delivered to rail track switch on.This known structure is to regulate the tierod that is screwed into the sleeve two ends or pusher by the centre part of the latching device that has reverse bush whorl.The centre part of this structure has the connecting strap that turn-out track drives, and in this known structure, suggestion cooperates as insulation sleeve the screw thread of sleeve with centre part usually, to reach the insulation effect.At this, this insulating sleeve is subjected to the effect of pulling force and pressure, and under the situation of vibration tension, exists the loosening fully danger of sleeve, thereby lost the position that mixes up in advance.So the power of transmitting by the insulating sleeve that cooperates with the blind hole of centre part is limited.In the similar structures that German patent DE-AS 1 279 711 proposes, vertically the internal diameter in hole is greater than the overall diameter of screw thread bush in the adapter sleeve, and suggestion is poured into a mould screw thread bush with the electrically insulating material skin.In this structure, insulating intermediate layer axially is subjected to shearing action, thereby causes sleeve loosening and lose the position that mixes up under the situation of long-term sustained vibration tension.
For fear of this disadvantageous power transmission on plastic interlayer, German patent DE-OS 2 239 493 has proposed a kind of structure and effect that insulating intermediate layer only is stressed basically.For this reason, the centre part of turn-out track driving connecting strap has the cone tank that outwards dwindles of two acting in oppositions, puts into a bolt with corresponding conical head in the groove.The outer rim of bolt cap is wrapped with insulating material, and at the cone tank of putting under the situation of insulating intermediate layer by the pusher parts that the gap portion of tie bolt is screwed into centre part that is screwed into.Like this, the effect of only being stressed of the interlayer on the end face between pusher parts and the centre part and help interlayer but still is subjected to the effect of shearing, thereby can readjusts in the scope of tie bolt head.In addition, the assembling complexity of this structure, and tie bolt head scope in taper fitting or the structure of tapering also be a problem.If advise as DE-OS 2 239 493 here, pass the part of tie bolt and prevent to reverse with a locking pin with the part of tie bolt bonded assembly pusher parts, the then this torsional mode that prevents is limited with respect to only keeping the anti-torsion effect of bonded assembly tie bolt with friction, because when the friction force of middle parts cone tank is overcome, this root tie bolt itself also can produce and reverse.Generally speaking, when adhesion connection between tie bolt and centre part or frictional connection become flexible, then with respect to the effect of centre part with regard to not preventing to reverse.
The objective of the invention is to, simple and the easy insulation of the assembling pusher structure of a kind of manufacturing is proposed, this structure both can be formed the pusher structure that has or do not have drive link application of force handle by array mode, can prevent that the pusher parts from reversing with respect to centre part and mutual generation of centre part each several part simultaneously again reliably.Simultaneously, the present invention also aims to, only affact on the insulating intermediate layer by the mutual chucking of each part of pusher and the power that produces that is in operation, and make insulating material only be subjected to very little wearing and tearing with the form of pressure.
In order to address this problem, the adjustable, insulating pusher that the present invention proposes or the structure of tierod are: sleeve has an anti-twist pin nail or a bolt that is positioned at outside the axis at least at its inner end surface opposite with the free end that is screwed into rod member, and sleeve is connected with each other with an eccentric bolt or another root tie bolt at least, the centre part that control lever application of force handle is used of packing in case of necessity, and turn round bolt or/and on the end face of tie bolt scope insulating barrier is set anti-.Because sleeve has at least an anti-twist pin outside being positioned at axially to follow closely or bolt on its inner end opposite with the free end that is screwed into parts, therefore, when sleeve is assembled on the centre part, can guarantee to prevent that the centre part each several part from reversing mutually, sleeve can be assembled under the situation that embeds a lever handles, also can directly two sleeves be assembled, and make the effect that the insulating barrier between the sleeve (having the centre part that is used for lever handles in case of necessity) only is stressed that is arranged in.
Threaded sleeve both can connect by eccentric bolt, also can simply by of making by eccentric pin prevent that turning round screw is connected with another root tie bolt, simultaneously, must consider on the anti-end face of turning round in bolt and/or the tie bolt scope to insulate.Shown in a most preferred embodiment of the present invention, if when another above-mentioned root tie bolt is axial bolts, the transmission of power is advantageous particularly then, assembles also simple especially.In this structure, the tierod member can be tightened with the screw thread of sleeve reliably, and this structure can assemble by the mode of latching device, and two ends are with positive and negative two kinds of screw threads.When in batches using the tierod member of same structure, two kinds of screw threads of sleeve must be a kind of is right-hand screw thread, and another kind is a minus thread, and while non-conductive centre part can be assembled by suitable mode.The structure that need not above-mentionedly have the tie bolt of a locating dowel pin and an approximate centre, also available following structure: sleeve respectively has a flange at the opposite coupling end of insertion end, under the situation that embeds insulating barrier, at least passing flange with a bolt couples together sleeve, under the situation of the centre part that embedding operation bar handle is used, this assembling also can be simple especially, and have only pressure basically, thereby reached the long and reliable purpose of period of service in the power that assembling and when operation produce.
Owing in the scope of bush whorl,, thereby reach additional anti-torsion effect with especially simple mode without any need for other insulating barrier.In order to reach this purpose, be screwed into consider at least on the parts of sleeve an axial groove or radially pin-and-hole produce engagement force and reverse preventing, by in the circumferencial direction of insertion end, suitably staggering some axial grooves or pin-and-hole are set simultaneously, can when very little position of rotation changes, reach quite accurate and axially adjust.
Tie bolt is tightened facing to insulating barrier under the situation of putting into a distribution of pressure pad, is particularly advantageous structure.Like this, needn't be meticulous especially when assembling, and available general impact tightening device assembles.
The rod end of pusher is screwed in the screw thread of the centre part of making by latching device, in case of necessity, can be in a conventional way prevents rotation with respect to centre part with nut and block nut, because do not need other insulation on this position.Owing in screw thread bush,, not only can just can prevent to reverse, and can adjust at the scene and do not need the additional examination situation that insulate by the fixing screw that inserts in the axial groove without insulating material.
Describe the present invention in detail below in conjunction with embodiment shown in the drawings.
Fig. 1 represents to have the first kind of structure centre part of lever handles (not with) of the centre part that is screwed into pusher;
Fig. 2 represents second kind of structure of this centre part, and part is a cross sectional drawing;
Fig. 3 represents to be embedded with by Fig. 2 band a kind of structure of the sleeve of lever handles centre part;
Fig. 4 represents to be embedded with by Fig. 1 the enlarged drawing of the centre part of lever handles, and part is a cross sectional drawing.
As seen from Figure 1, the sleeve 2 of band negative thread 1 interconnects with bolt under the situation of the non-conductive interlayer 4 that the inside face or the end face of insertion end 3 are being encased inside the effect of being stressed at it.Prevent that with a locating dowel pin 5 two sleeves from reversing, and firmly connect two sleeves with an axial attaching screw 6.Axially attaching screw 6 itself can prevent from again to reverse because, it have one radially pin-and-hole 7 can insert anti-twist pin nail.Because prevent to reverse by locating dowel pin or anti-twist pin nail 5, attaching screw 6 itself also has anti-torsion effect, so also prevented from reliably to reverse even minimal shrink occurs in the insulation component scope under certain conditions.
The insertion end 3 of sleeve 2 is screwed into a pusher member 8 respectively, and two interconnective sleeves constitute by latching device, and therefore, the rotation by two sleeves is with regard to the axial length of scalable pusher.The bolt that inserts has an axial groove 9 on pusher member 8, insert in this groove and prevent to rotate pin 10, thereby formed a firm and reliable especially structure.
In structure shown in Figure 2, be still two sleeves 2 and directly connect, and the centre part that does not have embedding operation bar handle to use.As shown in the figure, the sleeve 2 of band negative thread 1 has a flange 11 respectively in its inner end opposite with insertion end 3; Tie bolt 12 passes flange 11.Here, connection power also is to be born by the insulating intermediate layer 4 that acts on that only is stressed basically between sleeve 2 end faces, and the insulation in the scope of tie bolt 12 also must make the form of insulation sleeve 13.Cover 13 has annular lip 14, and puts into a distribution of pressure pad 15 between bolt head and annular lip 14, to prevent damaging insulation when assembling.
Generally speaking, the assembling of this pusher only needs identical commutation push rod member 8 and two identical sleeves 2.When sleeve has flange 11, then prevent to rotate by being positioned at several outer tie bolts of axis.
If additionally make the handle of control lever, then only need an additional centre part, and do not need miscellaneous part is carried out any modification with a centre part.The structure of sleeve 2 flanged 11, as shown in Figure 3.At this moment, centre part 16 has the point of action 17 of control lever, and itself has two flanges 18 to be connected with flange 11 by bolt 19 again.Generally speaking, as the structure of Fig. 2, only use identical parts, and between the insulation annular lip 14 of the head of bolt 19 and insulation sleeve 13, put a distribution of pressure pad 15.
In order to improve insulating power, the clear insulating intermediate layer 4 that illustrates of Fig. 4 can be made such shape, promptly insulating intermediate layer 4 has the sponson of a ring-type to be overlapped on the outside of sleeve 2 or centre part 20, thereby stops moisture to immerse in the scope of insulating intermediate layer.
