Abstract
The invention relates to a railway fastener, a rail fixer with antitheft function, designing two stop holes of spring end head on its base seat, when a special-shaped is inserted in the stop holes, because the end heads of the stop holes are closed, the spring can not withdraw and only using specially-designed key and spring-withdrawing wedge rod can withdraw the spring to complete demounting. It solves the difficult problem of the railway fasters being stolen for a long time past, protects the railway properties against heavy economic losses and ensures the driving safety of railway.
Description
The present invention relates to a kind of railway track fastener, belong to constructing of railroad track.
Railway track fastener is various in style at present, and performance has their own characteristics each, but does not possess anti-theft feature.Therefore, the railway of China is often stolen the railway track fastener incident.After the railway fastener is stolen, causes economic loss not only for the railway owner, and cause grave danger, even the heavy losses of car crash take place to railway transportation driving and safety.
The objective of the invention is to develop a kind of simple in structure, easy to use, firm and durable, maintenance capacity is little and the railway track fastener of reliable anti-theft feature arranged, with reach railway track laying fast, traffic safety, have the purpose of reliable anti-theft feature.
Solution of the present invention is a kind of two retainings of design hole base, uses the elasticity tightening force of deformed spring, and the two ends of pressing the rail deformed spring is squeezed in the two retaining of the base hole.Under the powerful tightening force effect of deformed spring, spring two terminations head into the retaining hole, retaining Kong Yiduan sealing, and the spring dismounting is had no way of doing it, and plays antitheft effect.For not only antitheft but also can dismantle, the present invention is at keyhole littler than spring diameter of spring limit thigh retaining hole opposite side design, and in keyhole threading.The key screw thread cooperates with the keyhole screw thread, and key inserts keyhole, along screw thread rotation in the retaining hole, specialshaped button pressing spring limit thigh end can be ejected the retaining hole, squeeze at side channel and carve bar, lift spring side thigh end, play spring with hammering and lever up end greatly, spring promptly all withdraws from, and finishes dismounting.In order further to protect fastener to avoid theft, the present invention has designed a kind of fusible alloy, pours into sealing after keyhole can being melted with fusible alloy, makes keyhole hidden.During the dismounting solid track device, available alcohol blast burner burns fusible alloy, exposes keyhole, uses the key ejector spring again, lifts side thigh strike spring height with tapered bar and levers up end, can withdraw from spring, finishes dismounting.
The present invention has following advantage:
1. the present invention is simple in structure, and is cheap, and reliable anti-theft feature is arranged, and protected the safe operation of railway.
2. the present invention has designed the special dismounting key, can implement dismounting when needs are dismantled.
3. the present invention is in order to reach the method that infallible anti-theft feature has also designed the fusible alloy sealed key hole.The dismounting of going that the robber dare not do evil things openly is stolen.
The present invention is described in further detail below in conjunction with accompanying drawing and specific implementation method.
Fig. 1 is the elevation of anti-theft type railroad track solid track device of the present invention
Fig. 2 is the top plan view of anti-theft type railroad track solid track device of the present invention
Fig. 3 is the side cutaway view of anti-theft type railroad track solid track device of the present invention
Diagram anti-theft type railroad track solid track device is to be made of deformed spring [11] and steel socket [1].Base top is provided with strand retaining hole seat [2] and spring side thigh retaining hole seat [3] in the spring that fixing spring uses, also be provided with on the base with keep off hole seat [3] retaining hole concentric with the footpath spring side thigh hugging [12] and dismantle spring with moving back spring side channel [8], two legs [13] is arranged at this base bottom, so that be embedded in the sleeper during prefabricated sleeper.When placing an iron railway, track [14] is put on two planes that keep off between the hole seats [2] of solid track device base [1], then in the deformed spring [11] strand is inserted in the retaining hole [4] that keeps off hole seat [2], beat the low end that levers up of spring with hammering, thigh all enters the retaining hole in treating, impact spring side thigh termination again, make in its retaining hole [5] that enters retaining hole seat [3], promptly finish track laying.Retaining hole [4] and the sealing of [5] one ends, spring two can't be withdrawed from after entering the retaining hole, has played antitheft effect.
In order to dismantle track, retaining hole [5] blind end is provided with the keyhole [6] of band negative thread, and this keyhole has used fusible alloy [10] that its shutoff is hidden before base dispatches from the factory.
When the dismounting track, keyhole [6] with alcohol blast burner heating retaining hole seat [3], with the fusible alloy [10] in hole [6] fusing, and liquation sprayed, then having and the pin thread key [7] of keyhole female thread inserts rotation in the keyhole [6], key is along screw advancement, deformed spring side thigh is ejected from retaining hole [5], use tapered bar [9] to squeeze into spring side thigh bottom again and lever up spring side thigh, impact the spring height again and lever up end from base side channel [8], can withdraw from spring, finish dismounting.
Claims (3)
1. anti-theft type railroad track solid track device, its base [1] setting are that the retaining hole is half through hole between first speed hole, the two ends seat [2], [3] of deformed spring [11].Insert from the openend in the retaining hole [4] of retaining hole seat [2] burst termination in the spring, and hit spring and enter entirely in the retaining hole [4], because the retaining hole other end is sealing, so burst termination can not pass from the retaining hole other end in the spring.Spring is beaten spring side thigh with hammering under the crunch effect, side thigh termination then enters in the retaining hole [5] in retaining hole [3], and retaining hole [5] other end is also for sealing, so spring can not take out.Spring and submount material adopt in addition heat treatment of high hard material, so it is moving to adopt hacksaw also to be difficult to saw, have played antitheft effect.
2. anti-theft type railroad track solid track device according to claim 1 is characterized in that retaining hole [5] the closed section design that keeps off hole seat [3] has a keyhole [6], and there is negative thread this inside, hole, and key [7] also has the pin thread that matches.When key inserts keyhole [6] rotation, key inwardly promotes spring side thigh along screw thread and withdraws from retaining hole [5], use tapered bar [9] to insert base side channel [8] medi-spring side thigh bottom again, hit tapered bar [9], spring side thigh is lifted, play spring with hammering again and lever up end greatly, spring can all withdraw from, and finishes dismounting.
3. according to the described anti-theft type railroad track of claim 1 solid track device, it is characterized in that pouring into after the available fusible alloy fusing and forming metal shutoff [10] in the keyhole for for the purpose of the insurance more, make keyhole hidden.When needing the dismounting track, heat fusible alloy with alcohol blast burner, the fusing back is sprayed from the hole by alcohol blast burner flame, exposes keyhole, adopts the described method of claim 2 again, can pull down spring, finishes the railway sleeper dismounting.
