Abstract
A railway track fastener locking and retaining system comprises a locking and retaining bolt/locking and retaining anchor bolt, a locking and retaining elastic washer and a locking and retaining iron base plate. The cross section of the locking and retaining elastic washer is of a conical shape protruding upwards. The lower end face of the locking and retaining bolt head and the upper end face of the locking retaining elastic washer are radially provided with saw teeth. The locking and retaining bolt head and the locking and retaining elastic washer are locked and matched in a wedge manner by the aid of the saw teeth. The lower end face of the locking and retaining elastic washer and the upper end face of the locking and retaining iron base plate are locked and matched with each other. The railway track fastener locking and retaining system has the advantages that when tightening torque is 150-350N.m, loosening can only occur when loosening torque is larger than the tightening torque; when the tightening torque is 350N.m, the loosening torque can even reach above 400N.m, and accordingly good locking effect is achieved, retightening times of the locking and retaining blot/locking and retaining anchor bolt are reduced, workload of railway workers is reduced, and potential safety hazard is lowered.
Description
Technical field
The utility model belongs to railroad track and uses fastener technology field, relates to a kind of Anti-loosen stop system, particularly railway track fastener Anti-loosen stop system.
Background technology
Along with development in science and technology and social progress, the railway of China's construction is more and more, and the impact on Along Railway resident when alleviating train operation can arrange fastener conventionally between rail and sleeper, for connecting rail and sleeper, plays the effect of vibration and noise reducing simultaneously.Early stage fastener major part is all connected with sleeper by bolt, under the repetitive loading effect that bolt passes through at train, often occur loosening, bolt after loosening will not have fastening effect, can have influence on traffic safety, need regular inspection to twist again to ensure at any time bolton for this reason, make railway worker's workload larger, and have potential safety hazard.Increased afterwards heavy-duty spring packing ring as locking parts, but the load that heavy-duty spring packing ring provides is inhomogeneous, and anti-loosing effect is bad.People had designed again disk spring washer afterwards, and through experimental results show that disk spring washer uses as locking parts, it is stressed more even in the time that bolt tightens, and anti-loosing effect is better than heavy-duty spring packing ring, experimental data is as shown in table 1, but from experimental data, while being 150N.m by the tightening torque of bolt and heavy-duty spring packing ring, loosening moment of torsion is 90～100N.m, while being 150N.m by the tightening torque of bolt and disk spring washer, loosening moment of torsion is 100～110N.m, loosening moment of torsion is much smaller than tightening torque, so heavy-duty spring packing ring and disk spring washer all can not reach desirable anti-loosing effect.
Summary of the invention
The utility model is in order to overcome the defect of prior art, design railway track fastener Anti-loosen stop system, in train driving motion, Anti-loosen stop system can not become flexible naturally, only be subject to the effect of external force, and suffered external force just can be become flexible while being greater than maximum tightening torque, can play well anti-loosing effect, reduce the stubborn number of times again of Anti-loosen stop Luo Shuan ∕ Anti-loosen stop anchor bolt, reduce railway worker's workload, ensure the traffic safety of train simultaneously, reduced the potential safety hazard in train travel.Experiment showed, that this Anti-loosen stop system, in the time that tightening torque is 150～350N.m, just can become flexible when loosening moment of torsion is greater than tightening torque.When tightening torque is 350N.m, more than loosening moment of torsion even can reach 400N.m.
The concrete technical scheme that the utility model adopts is: railway track fastener Anti-loosen stop system, comprise Anti-loosen stop Luo Shuan ∕ Anti-loosen stop anchor bolt, Anti-loosen stop elastic washer, Anti-loosen stop iron chair, Anti-loosen stop Luo Shuan ∕ Anti-loosen stop anchor bolt comprises Anti-loosen stop bolt head and Anti-loosen stop bolt column, on Anti-loosen stop iron chair, offer bolt hole, Anti-loosen stop elastic washer, Anti-loosen stop iron chair is sleeved on Anti-loosen stop bolt column successively, the cross section of Anti-loosen stop elastic washer is raise up tapered, key is: the lower surface of described Anti-loosen stop bolt head and the upper surface of Anti-loosen stop elastic washer have all been disposed radially sawtooth tooth, locking coordinates by sawtooth dentification Wedged for Anti-loosen stop bolt head and Anti-loosen stop elastic washer, the upper surface of the lower surface of Anti-loosen stop elastic washer and Anti-loosen stop iron chair complements each other to form locking and coordinates.
The beneficial effects of the utility model are: locking coordinates by sawtooth dentification Wedged for Anti-loosen stop bolt head and Anti-loosen stop elastic washer, Anti-loosen stop elastic washer and Anti-loosen stop iron chair also form locking and coordinate, in the time that tightening torque is 150～350N.m, when being greater than tightening torque, just can become flexible loosening moment of torsion.When tightening torque is 350N.m, more than loosening moment of torsion even can reach 400N.m, can play well anti-loosing effect, reduce the stubborn number of times again of Anti-loosen stop Luo Shuan ∕ Anti-loosen stop anchor bolt, reduce railway worker's workload, ensure the traffic safety of train simultaneously, reduced the potential safety hazard in train travel, can be applicable in the multiple railway track fasteners such as state's iron, subway, urban light rail.
The upper surface of Anti-loosen stop iron chair is provided with boss, bolt hole is the manhole that runs through Anti-loosen stop iron chair, locking coordinates by sawtooth dentification Wedged for Anti-loosen stop elastic washer and Anti-loosen stop iron chair, this integral structure of boss and Anti-loosen stop iron chair, more convenient while making to install.
Bolt hole is slotted hole, increase Anti-loosen stop roll adjustment buckle, the break-through of Anti-loosen stop roll adjustment buckle is on Anti-loosen stop bolt column, between Anti-loosen stop elastic washer and Anti-loosen stop iron chair, locking coordinates by sawtooth dentification Wedged for Anti-loosen stop elastic washer and Anti-loosen stop roll adjustment buckle, locking coordinates by bar shaped dentification Wedged roll adjustment for Anti-loosen stop roll adjustment buckle and Anti-loosen stop iron chair, by changing the position of Anti-loosen stop roll adjustment buckle in bolt hole, can change the position of Anti-loosen stop Luo Shuan ∕ Anti-loosen stop anchor bolt, more simple and convenient while making to withhold fastener.
The height of sawtooth tooth is 1.5～2.5mm, highly higher, and corresponding loosening moment of torsion is larger, and anti-loosing effect is better.The central angle alpha that each sawtooth tooth is corresponding is 15～18 °, and central angle is less, and the quantity of sawtooth tooth is more, and corresponding loosening moment of torsion is larger, and anti-loosing effect is also just better.The coning angle of Anti-loosen stop elastic washer is 3～10 °, and the larger expanding force of coning angle is larger, and corresponding locking moment of torsion is larger.
