Abstract
The invention discloses a two-way adjusting non-buckle shaft sleeve device capable of synchronously moving, which is used for the connection of eyelet bolts and a screw connector of common turnout and connectors of connecting indication rods of speed-raising turnout. When a non-buckle shaft sleeve on a screw rotates forwards or backwards, a notch and a protruding tongue arranged on the edge of the convex body of the non-buckle shaft are interlocked and tightly pull a notch and a protruding tongue arranged on the edge of the convex body of a shaft sleeve with a buckle, so that the non-buckle shaft sleeve synchronously moves on a threaded rod with the shaft sleeve with the buckle, the adjustment standard is achieved, the purpose of synchronous moving during two-way adjusting is realized, meanwhile once a nut for fastening the non-buckle shaft sleeve is loosened, the non-buckle shaft sleeve does not get loose easily, and the device is safer and more reliable in use and the adjustment is more convenient and efficient.
Description
Technical field:
The present invention relates to a kind of railway switch connecting rod uses without buckle shaft covering device, be particularly suitable on the eyelet bolt on common track switch, spiral shell buckle joint and acclerating road switch connect indication rod joint on.
Background technology:
Railway switch connecting rod is used for connect these connectors such as eyelet bolt, spiral shell buckle joint, joint be usually all employing one have buckle shaft to overlap and one to be set in the through hole of connector without buckle shaft cover and to be clamped, then will without buckle shaft for fasten with nut.When needing adjustment connector, first the standby jack panel overlapping one end without buckle shaft is loosened, rotate without buckle shaft cover, being driven by two mutual torsion of axle sleeve convex-concave structure has buckle shaft to overlap rotation, when being enclosed within backwards rotation adjustment on thread rod without buckle shaft, there is buckle shaft to be enclosed within screw rod to move toward this one end without buckle shaft cover, now just by the propelling thrust that has buckle shaft to overlap to promote connector together with overlapping without buckle shaft towards right direction synchronizing moving, easily connector can be adjusted to correct position; But, when to be enclosed within without buckle shaft on thread rod forward rotate adjustment time, have buckle shaft to be enclosed within screw rod to move to overlapping this contrary one end without buckle shaft, by the gravity of connector itself and pulling force compel, buckle shaft cover is now had to deviate from the through hole of connector, have buckle shaft cover to be separated with the convex-concave structure part of overlapping without buckle shaft, rotate and buckle shaft cover can not have been driven mobile without buckle shaft cover, the at this moment movement of connector just needs by artificial push-and-pull or has knocked.Moreover the standby tight nut without buckle shaft cover of this structure is once loosen, connector will overlap this one end without buckle shaft and is shifted equipment is changed by the impact of external force and train vibrations is past.Therefore there is adjustment inconvenience and the shortcoming such as stability is bad in this apparatus structure, brings inconvenience on site maintenance work, and adjustment duration, equipment use instability jeopardizes traffic safety.For solving the problem, the multinomial patent such as No. 97215190.7th, Chinese patent " gap adjustable bolt ", No. ZL98249721.0 " can spinning regulating screw joint ", No. ZL20082002856.3 " elastic release proof self-locking dog bolt trimmer ", No. 201120274702.0 " fine adjusting device for speed acceleration turnout indication gap ", successively all have employed and terms of settlement is proposed to the problems referred to above, to overcome above-mentioned deficiency by having buckle shaft to overlap and without buckle shaft cover, connector being clamped multiple different processing technology and the mode such as to be integrated.The enforcement of these schemes also solves above-mentioned Problems existing really, but along with the use for many years of this technology finds, because described in top, the structure of technique is non-removable, manufacturing cost is high, use the frequent oiling of middle needs, if keep in repair improper easy corrosion and turn motionless in use all the year round, this is also corresponding brings inconvenience on site maintenance, once corrosion turns motionless will affect driving, therefore this is not also the technical measures of more satisfactory field demand, can not meet maintenance requirements on-the-spot at present.
Summary of the invention:
The present invention is deficiency for solving above-mentioned existence and provides a kind of two-way adjustment can be synchronization-moving without buckle shaft covering device, it is low cost of manufacture not only, install simple, adjust convenient to use, and decomposable asymmetric choice net detachable maintaining, be not easy corrosion, during adjustment no matter forward or backwards rotation without buckle shaft cover, connector synchronizing moving can be driven, and at the standby tight nut without buckle shaft cover once loosening, also can not get loose easily without buckle shaft cover, use more safe and reliable.
The invention discloses a kind of two-way adjustment can be synchronization-moving without buckle shaft covering device, comprises without buckle shaft cover and has buckle shaft cover, it is characterized in that: described one end without buckle shaft cover is the gengon other end is cylindrical shell, laterally through circular hole is provided with between gengon and cylindrical shell, cylindrical shell end is laid with two convex bodys on two symmetrical concave grooves and concave groove both sides, two edges of two convex bodys are respectively equipped with recess and convex tongue by concave groove root to end, described one end having buckle shaft to overlap is gengon, also can be cylinder, the other end is cylindrical shell, laterally through tapped bore is provided with between gengon and cylindrical shell, cylindrical shell end is laid with two convex bodys on two symmetrical concave grooves and concave groove both sides, two edges of two convex bodys are respectively equipped with recess and convex tongue by concave groove root to end, the described recess that arranges without buckle shaft cover convex body edge and convex tongue and have buckle shaft to overlap convex tongue that convex body edge arranges and recess mutually corresponding.
The present invention has the following advantages compared with existing technology: the maximum feature of the present invention is the structure not needing to change former connector, only need change and to overlap without buckle shaft and to have buckle shaft to overlap the convex body on concave groove both sides on two shaft sleeve body regions, just can meet operating needs.Instant invention overcomes in prior art without can not synchronization-moving deficiency during the backwards rotation adjustment of buckle shaft cover, also prevent the standby nut tightly overlapped without buckle shaft simultaneously and overlap without buckle shaft the phenomenon easily getting loose and be shifted once loosen, achieve no matter without buckle shaft cover forward or backwards rotation adjustment can drive connector synchronizing moving, it is made to reach fast easy to adjust, safe and reliable, and have that structure design is simple, easy to process, low cost of manufacture, be easy to fitting operation and be connected firmly, the advantages such as cleaning maintenance can be decomposed.Strong adaptability of the present invention, just can be met the equipment use of different size model by the finish size changing shaft sleeve device, popularizing value is high.
