the lifting block 4 is of a cylindrical structure with a hollow screw rod in the middle, the upper part of the screw rod 8 is a smooth surface and extends into the lifting block 4 to be closely attached to the lifting block 4, the surface of the middle part of the screw rod is carved with threads and is arranged in the steel pillow supporting block 5 to be in threaded connection with the inner wall of the steel pillow supporting block 5, the surface of the lower part of the screw rod is also carved with threads and sequentially penetrates through the middle parts of the sawtooth rotating wheel 6 (the sawtooth wheel 61 and the convex gear 62) and the fixed disc 7 to be in threaded connection with the inner walls of the sawtooth rotating wheel 6 and the fixed disc 7 respectively.
Working process
Assembling equipment: installing parts of each part at an initial position according to the sequence from inside to outside and from bottom to top, and laying steel rails and fasteners for installation;
when a train passes by, the acting force of the train wheels on the steel rail is transmitted to a ballast bed through the lifting block 4, the screw 8, the steel sleeper supporting block 5, the sawtooth rotating wheel 6, the fixed disc 7 and the bottom of the steel sleeper, at the moment, the top of the screw 8 is tightly contacted with the lifting block 4, the steel sleeper moves together with the steel rail, and if the ballast bed or a roadbed subsides, the steel rail generates downward elastic bending deformation under the action of wheel load;
thirdly, after the train wheels leave, the elastic deformation of the steel rail is recovered to generate a huge upward elastic force to drive the lifting block 4 to move upward together, so that the top of the screw 8 is separated from the lifting block 4, and the top of the screw 8 loses support, therefore, the pinion 72 of the built-in spiral spring 73 on the fixed disc 7 starts to rotate counterclockwise (the top view of fig. 4 is the same as the top view of fig. 4) under the action of the mechanical energy initially stored by the spiral spring, thereby driving the convex gear 62 meshed with the pinion to rotate clockwise, the serrated wheel 61 fixedly connected with the convex gear 62 also rotates clockwise, i.e. the pawl 71 slides along the saw teeth 63 of the serrated wheel 61, meanwhile, the clockwise rotation of the serrated wheel 6 also drives the screw 8 to rotate counterclockwise through the threads, so that the screw 8 rotates and rises until the bottom of the lifting block 4 is propped, thereby forming a new mechanical balance system, the displacement of the screw 8 which rotates and rises just compensates the settlement generated by the lower foundation, and the overall height of the settlement compensating device is unchanged;
and fourthly, when the train passes through again, the acting force of the wheels of the train on the steel rail is still transmitted to the track bed through the lifting block 4, the screw 8, the steel sleeper supporting block 5, the sawtooth rotating wheel 6, the fixed disc 7 and the bottom of the steel sleeper, if the lower foundation is settled, the adjusting process is repeated, if the lower foundation is not settled, the pawl 71 and the sawtooth wheel 61 slide in one direction, the pawl 71 is inserted into the tooth space of the sawtooth 63, the sawtooth rotating wheel 6 is prevented from rotating reversely, namely the sawtooth rotating wheel 6 cannot rotate anticlockwise, the screw 8 is prevented from rotating clockwise and descending, and all parts in the steel sleeper structure are kept still.
The above embodiments are only preferred embodiments of the present invention, and the structure of the present invention is not limited to the forms of the above embodiments, and any modifications, equivalents and the like within the spirit and principle of the present invention should be included in the protection scope of the present invention.
