Description
Technical field
The present invention relates to railway traffic equipment, especially a kind of track bolt-type adjustably adjusts anti-creeping strut.
Background technology
When train the section main track of double-tracking railways, the loaded vehicle direction of single-track railway, long heavy down grade, sharp radius curve with
And within the scope of braking when entering the station when driving, the longitudinal force on rail is usually acted, rail is made to vertically move, sometimes
Even sleeper is driven to move together, this longitudinal movement is called " creeping ".Track creeping often causes rail gap irregular, and sleeper is askew
The consequences such as oblique, it is very big to the destructiveness of circuit, or even small rail swelling track is caused, jeopardize traffic safety.Therefore, it is necessary to take effectively
Measure prevents track creeping, the purpose is to reinforcing the integral strength of track structure, increases the stability of circuit, ensures driving peace
Entirely.The equipment for preventing railway from making to vertically move usually is known as anti-creep equipment, there are mainly two types of current most common anti-creep equipment,
One is anticreeper, another kind is anti-creeping strut.
Now widely used China is drift-pin type anticreeper, and in order to give full play to the effect of anticreeper, people are usual
A certain number of anti-creep supports can be installed between online rail pillow, it is common to resist circuit creeping force to form it into an entirety.
Wherein, anti-creep support can use the manufactures such as wood materials, building stones or armored concrete, although three is preventing to climb with regulation circuit
Be widely applied during row disease, but its still there are some drawbacks.On the one hand, existing anti-creeping strut is pre- in factory
System processing, size is relatively fixed, so being suitable only for certain specific sleeper spacing.However, but there are a variety of sleepers in China
Separation criteria, wherein most commonly used is every km 1680,1760 and 1,840 three kinds of sleeper spacing, therefore it is existing anti-
The general another aspect in all kinds of sleeper spacing can not be accomplished by climbing support, federation's inevitable real estate when due to being laid with sleeper at the scene
Raw certain error, this may result in the practical spacing between sleeper and is not inconsistent with prefabricated anti-creeping strut size, to cause anti-creep
Supportting the drawbacks such as can not install or not work after installing.
Invention content
It is an object of the invention to provide a kind of track bolts easy for assemble or unload, versatility is good, structure stress is strong
Formula adjustably adjusts anti-creeping strut.
The track bolt-type of the present invention adjustably adjusts anti-creeping strut, including stress top plate, anti-creep box, head cover, head cover pass through
Hinge is connected with anti-creep box, and head cover is used for overhauling, which is characterized in that cavity horizontal direction one end closing in anti-creep box, one
End is open end, is provided with equally distributed latch groove on the inner wall of anti-creep box both sides, compression spring is fixed in latch groove, trapezoidal bolt one
End is inserted in latch groove to be connected with compression spring；The telescopic frame of stress top plate is inserted into from the open end of cavity in cavity, stress top
The telescopic frame of plate is hollow structure, and bottom is equipped with spur rack, two F shapes sliding blocks and reseting gear built in centre, F shape sliding blocks
Outer vertical edge edge is respectively unidirectional sawtooth with interior lateral edge and resets spur rack, and the reset spur rack of reseting gear and F shape sliding blocks is nibbled
It closes, reseting gear is connected with the reset bolt at the top of telescopic frame, and the two can rotate synchronously, and the forward and reverse rotation of reseting gear can be controlled
The in the same direction or counter motion of two F shape sliding blocks is made, the outer end of anti-creep box inner wall upper trapezoid bolt and the unidirectional sawtooth of F shape sliding blocks are nibbled
Conjunction forms self-locking；Anti-creep cassette bottom portion is equipped with equipment gear, and equipment gear is connect with the adjusting bolt of its both sides, and stress top plate is stretched
The spur rack of contracting frame bottom is meshed with equipment gear, and adjusting bolt drives stress top plate telescopic frame to move by equipment gear.
It is that the novel anti-creeping strut is placed in two first that the track bolt-type of the present invention, which adjustably adjusts anti-creeping strut operation principle,
Between target sleeper, then rotate clockwise adjusting bolt with spanner with drive assist tooth crop rotation rotate synchronously, it is at the same time, auxiliary
The interlocking between gear and flexible frame bottom spur rack is helped, telescopic frame is pushed to move forward, until stress top plate and anti-creep
Box respectively with the closely connected stress of both sides sleeper.At this moment, the unidirectional saw that trapezoidal bolt will be under the promotion of high pressure spring with F shape sliding blocks
Tooth is mutually engaged, and to achieve the purpose that be moved after preventing telescopic frame from shrinking, limits the size of anti-creeping strut.Work is removed making anti-creeping strut
When, the head cover on anti-creep box top is opened first, then rotating clockwise former and later two with spanner resets bolt, in this way, flexible
The F shapes sliding block of the left and right sides will move under the drive of reseting gear to central reduction inside frame, and trapezoidal bolt is made to be slided with F shapes
The unidirectional sawtooth of block is separated, and realizes the unlock to the telescopic frame direction of motion, then rotates counterclockwise adjusting bolt with spanner again,
It is moved after so that telescopic frame is shunk under the action of equipment gear, is finally completed the dismantlement work of anti-creeping strut.
The track bolt-type of the present invention adjustably adjusts anti-creeping strut, passes through mutually stinging between trapezoidal bolt and unidirectional sawtooth
Close to achieve the purpose that adjust anti-creeping strut size, have versatility is good, structure stress is strong, retractable is adjusted, maintenance more
Change the advantages that convenient.
