The basic technical scheme has the beneficial effects that: the first buffer pad is connected with the steel rail, so that rigid connection between the steel rail and the sleeper is avoided, and the purposes of shock absorption and noise reduction are achieved; meanwhile, the steel rail is wrapped by the insulating layer, so that interference of external signals is effectively prevented; the lower side of the steel rail is connected with a hydraulic device, so that the steel rail can be self-regulated and is parallel to the tread of the tire wheel, the uneven abrasion of the tread of the tire wheel is avoided, and the service life of each track assembly is effectively prolonged.
Preferably, the hydraulic device is filled with filling liquid, and two support columns are arranged on the upper side of the hydraulic device and are in sliding connection with the hydraulic device.
Through the arrangement, when a certain supporting column is extruded, the other supporting column is moved upwards, so that the steel rail can be self-adjusted to be parallel to the tread of the tire wheel.
Preferably, the contact surface of the insulating gauge plate and the steel rail is connected with a second buffer pad.
Through the arrangement, vibration influence caused by horizontal impact force is effectively reduced, and vibration reduction and noise reduction in the horizontal direction are realized.
Preferably, the first bolt and the second bolt are stud bolts.
Through the arrangement, the stud can bear the tensile force and the shearing force of parts at the two ends of the stud, and the firmness of the connection of the parts at the two ends is increased.
Preferably, the first bolt is sleeved with a longitudinal spring, and the longitudinal spring is located between the first fixed block and the elastic strip.
Through above-mentioned setting, effectively reduce the vibrations between bullet strip and the first fixed block, utilize the elasticity of spring simultaneously, make the connection between nut and the bolt more fastening.
Preferably, the first bolt is sleeved with a flat washer, which is located on the underside of the nut.
Through the arrangement, the stress area is increased, the influence caused by vibration of the spring strip is reduced, looseness is not easy to occur between the nut and the bolt, and the service life of each part is prolonged.
Preferably, the second fixed block is connected with two limiting blocks, and the two limiting blocks are respectively positioned on the upper side and the lower side of the transverse spring.
Through above-mentioned setting, not only spacing to transverse spring, with its fixing in original place, when first bolt can not bear transverse impact force and take place to control the skew because of reasons such as ageing, the stopper can also prevent that it from continuing to control the skew, continues to bear transverse impact force by the second fixed block.
