[0016] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0017] Example 1

[0018] like Figure 1 , Figure 2 As shown, this utility model provides a high-temperature and corrosion-resistant high-load-bearing pad, including a pad 100, wherein the pad 100 includes an isosceles trapezoidal pad 200 and a cuboid pad 300; the isosceles trapezoidal pad 200 has grooves 210 on its left and right end faces; and square protrusions 400 are provided on both sides of the upper end face of the isosceles trapezoidal pad 200.

[0019] Preferably, there is at least one groove 210, which increases the heat dissipation surface area of ​​the left and right end faces of the pad 100, thereby improving the heat dissipation efficiency; the grooves 210 are of different sizes, which not only increases the strength and stability of the two sides of the pad 100, but also improves the heat dissipation efficiency; the rounded corners can effectively disperse stress and improve the overall strength and durability of the pad 100.

[0020] Preferably, the square protrusion 400 is an inwardly curved surface with an arc on the side perpendicular to the upper end surface of the isosceles trapezoidal pad iron 200, which can make the upper end surface of the pad iron 100 more uniform in stress, reduce the local high stress area, and thus prolong the service life of the pad iron 100.

[0021] Preferably, the length of the square protrusion 400 is equal to the length of the upper side of the isosceles trapezoidal pad iron 200, which prevents the square protrusion 400 from being too small to reduce stress or too large to cause the pad iron 100 to be heavier at the top and lighter at the bottom, affecting the overall stability.

[0022] Preferably, the length of the cuboid pad iron 300 is equal to the length of the lower side of the isosceles trapezoidal pad iron 200, which makes the bottom structure of the pad iron 100 more stable and thus improves the overall stability.

[0023] Preferably, the pad iron 100 has a high-temperature and corrosion-resistant coating on the entire outer side, and the high-temperature and corrosion-resistant coating is a polytetrafluoroethylene coating layer. The polytetrafluoroethylene coating layer is obtained by coating polytetrafluoroethylene paint on the entire outer side of the pad iron 100. Because polytetrafluoroethylene paint has excellent corrosion resistance and high temperature resistance, a high-temperature and corrosion-resistant coating is obtained on the entire outer side of the pad iron 100.

[0024] Example Two

[0025] As shown in Figure 3 , Figure 4 the present embodiment further comprises the following technical solutions based on example one: the isosceles trapezoidal pad iron 200 has first through holes 230 of the same diameter uniformly arranged at the middle position of the upper end surface; the cuboid pad iron 300 has second through holes 310 of the same diameter uniformly arranged, corresponding to the positions of the first through holes 230; the first through holes 230 and the second through holes 310 are of the same diameter and are in communication inside the pad iron 100; there is at least one of the first through holes 230 and the second through holes 310, and the number of through holes affects the number of heat conduction paths. The more through holes there are, the more heat can be absorbed and dispersed, and the higher the heat dissipation efficiency.

[0026] Preferably, the first through holes 230 are provided with spacers 220, and the length of the spacers 220 is consistent with the width of the upper end surface of the pad iron 100, and the width is less than the distance between the two first through holes 230. The size of the spacers 220 determines the size of the contact area. The larger the contact area, the more load can be distributed, which can reduce local stress concentration and thus improve the overall load-bearing capacity of the pad iron 100.

[0027] Preferably, the cushion block 220 can support the cast steel part, so that a gap is formed between the cast steel part and the cushion iron 100, and then the first through hole 230 and the second through hole 310 form a convection heat exchange. When the air flows, the heat on the surface of the cast steel part and the cushion iron 100 can be taken away, so as to reduce the temperature of the two.

[0028] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various modifications and changes to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
