Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
A thermoplastic elastomer antiskid base plate is shown by combining figures 1 to 5 and comprises a base plate body 1 which is paved between a steel rail and a sleeper, wherein the top surface and the bottom surface of the base plate body 1 are provided with a main antiskid lug boss 4 and an auxiliary antiskid lug boss 5; a blocking edge 2 is arranged on the bottom surface of the base plate body 1, and a bottom foot 3 is arranged below the blocking edge 2; the pad body 1 is provided with a sound absorbing layer 7 inside.
The backing plate body 1 is in a cuboid shape, the backing plate body 1 is made of a polyester thermoplastic elastomer material, the polyester thermoplastic elastomer has the elasticity of rubber and the strength of engineering plastics, and the backing plate made of the material can have better mechanical performance and prolong the service life of the backing plate.
As shown in fig. 1 to 2, the main anti-slip bosses 4 and the auxiliary anti-slip bosses 5 are used for anti-slip, and are both in a frustum shape. The diameter of main anti-skidding boss 4 is greater than the diameter of assisting anti-skidding boss 5, and main anti-skidding boss 4 and main anti-skidding boss 5 are even as an organic whole with backing plate body 1 to be evenly distributed on backing plate body 1. The main anti-slip bosses 4 are arranged at intervals along the transverse direction and the longitudinal direction of the top surface of the base plate body 1, and the auxiliary anti-slip bosses 5 are arranged at the central position between every two main anti-slip bosses 5. The auxiliary anti-slip boss 5 is arranged at the position, corresponding to the main anti-slip boss 4, of the bottom surface of the base plate body 1, the auxiliary anti-slip boss 5 is coaxial with the corresponding main anti-slip boss 4, the main anti-slip boss 4 is arranged at the position, corresponding to the auxiliary anti-slip boss 5, of the bottom surface of the base plate body 1, and the main anti-slip boss 4 is coaxial with the corresponding auxiliary anti-slip boss 5; the anti-skidding boss that lies in the top surface simultaneously just right with the slot 6 that lies in the bottom surface, and the anti-skidding boss that lies in the bottom surface is just right with the slot 6 that lies in the top surface, can make 6 positions of slot be unlikely to too thin for whole backing plate body 1's intensity is stronger, thereby ensures that backing plate body 1's fatigue resistance can be better and the structure is more stable.
As shown in fig. 4, the cross sectional area of the bottom surface of the main anti-slip boss 4 and the auxiliary anti-slip boss 5 connected with the base plate body 1 is larger than that of the top surface far away from the base plate body 1, so that the force required by downward compression of the main anti-slip boss 4 and the auxiliary anti-slip boss 5 at the height position is larger, a better buffering effect is achieved on a train running through the base plate, the contact area between the main anti-slip boss 4 and the auxiliary anti-slip boss 5 and the base plate body 1 is larger, the top part of the base plate body is smaller while the connection between the main anti-slip boss 4 and the auxiliary anti-slip boss 5 is firmer, and the static rigidity is reduced.
The arc chamfers are arranged on the top surfaces of the main anti-slip boss 4 and the auxiliary anti-slip boss 5, stress dispersion of the base plate body 1 under stress can be effectively improved through the arc chamfers, good bearing capacity and good elastic performance are achieved, and the service life of the base plate body 1 can be effectively prolonged.
All the main anti-skid bosses 4 are consistent in height, all the auxiliary anti-skid bosses 5 are consistent in height, and the main anti-skid bosses 4 are larger than the auxiliary anti-skid bosses 5 in height. When the base plate body 1 is subjected to pressure from a train, the base plate body 1 is compressed to the height of the main anti-slip boss 4 and the height of the auxiliary anti-slip boss 5, the base plate body 1 generates two different static rigidities respectively, so that the base plate body 1 meets the running requirements of trains with different weights, and the adaptability is good.
As shown in fig. 3, the blocking edges 2 are arranged downwards on two sides of the bottom surface of the tie plate body 1 corresponding to the length of the sleeper, and the blocking edges 2 are connected with the tie plate body 1 into a whole. The height of the blocking edge 2 is higher than that of the main anti-slip boss 4, and the blocking edge 2 can help to prevent sundries from entering the bottom surface of the base plate body 1 while preventing the base plate body 1 from moving.
The footing 3 sets up at the both ends that keep off along 2, and is even as an organic whole with keeping off along 2. The feet 3 are used for mounting and positioning the underlay sheet body 1.
As shown in fig. 5, a sound absorbing layer 7 is provided inside the pad body 1, and the sound absorbing layer 7 is made of a PET fiber material for reducing noise.
When the utility model is used, the base plate body 1 is fixed between the steel rail and the sleeper through the bottom feet 3, when a train passes through the steel rail, the weight is exerted on the base plate body 1, and the main anti-skid bosses 4 and the auxiliary anti-skid bosses 5 play a good role in buffering the running train; the grooves 6 and the sound absorbing layer 7 can greatly reduce the propagation of track noise.
