[0005] Its effect is that the bottom of the cushion block body is fitted with the surface of the beam, which increases the stress area of the beam, thereby reducing the local pressure of the beam and preventing the deformation of the beam. A groove is provided on the upper part of the cushion block body, which contacts with the U-shaped bolt to fix the beam cushion block.

[0006] Further, the groove is in the shape of a circular arc.

[0007] Its effect is that the circular arc groove can increase the contact area with the U-shaped bolt, thereby preventing the deformation of the U-shaped bolt due to excessive stress.

[0008] Further, the retaining edge is provided with a circular arc transition at the contact part of the groove and the left and right side walls.

[0009] Its effect is to prevent the U-shaped bolt from being scratched on both sides of the groove during installation and fixation.

[0010] Further, the groove is provided with a circular arc surface between the two ends and the front and rear side walls.

[0011] Its effect is to prevent water and dust accumulation.

[0012] Further, the left and right side walls are outwardly convex, and the cushion block body and the left and right side walls form a trapezoid.

[0013] Its effect lies in further increasing the area of the bottom and increasing the contact area with the girder stress part.

[0014] Further, the girder cushion block is integrally forged.

[0015] Its effect lies in being not prone to cracks and further reducing production cost. Beneficial effects

[0016] The girder cushion block of the utility model significantly increases the contact area between the U-shaped bolt and the girder, effectively disperses the load, reduces the local stress concentration, thereby reduces the deformation risk of the girder due to stress. By increasing the contact area, the utility model not only improves the safety performance of the vehicle, but also enhances the fit between the girder and the cushion block, ensures the stability and reliability of installation.

[0021] The technical scheme of the utility model and its beneficial effects are more clear and definite by further describing the specific implementation of the utility model in combination with the drawings of the specification. The following describes the embodiment by referring to the drawings is exemplary, and is intended to explain the utility model, and can not be understood as the limitation of the utility model.

[0022] First embodiment:

[0023] As Figure 1 Indicated, a kind of girder cushion block, including cushion block body 1, the bottom of the cushion block body 1 is fitting surface, and is fitted with girder surface, the left and right sides of the cushion block body 1 are left and right side walls 2, and front and back sides are front and back side walls 3, the upper portion of the cushion block body 1 is further provided with a recess 4, and recess 4 is through from front to back, and the recess 4 and left and right side walls 2 form baffle 5.

[0024] When in use, the groove 4 is in contact with the cylindrical surface of the bottom of the U-shaped bolt, the U-shaped bolt clamps the cushion block body 1, preventing the movement of the cushion block of the girder, and the installation is also more convenient. The bottom of the cushion block body 1 is in contact with the surface of the girder, and the stress area of the surface of the girder is pressed when the U-shaped bolt is pressed, preventing the deformation of the surface of the girder when the U-shaped bolt is pressed, and improving the safety of the girder.

[0025] The groove 4 is circular arc-shaped. The circular arc-shaped is more closely in contact with the U-shaped bolt.
