[0025] Reference Figure 1-Figure 3 , is an embodiment of the utility model, which provides a multifunctional bearing pad structure for a bridge, comprising:

[0026] The main body 100 includes a bottom plate 101, a lower pad 102 is fixedly connected to the top of the bottom plate 101, an upper pad 103 is arranged on the top of the lower pad 102, the upper pad 103 is detachably connected to the bottom plate 101, a rubber block 104 is placed on the top of the upper pad 103, four groups of connecting ear plates 106 are fixedly connected to the side wall of the upper pad 103, threaded columns 107 are fixedly connected to the positions of the top of the bottom plate 101 facing the four groups of connecting ear plates 106, the four groups of threaded columns 107 pass through the four groups of connecting ear plates 106 respectively, locking nuts 108 are arranged above the four groups of connecting ear plates 106, the four groups of locking nuts 108 are respectively threadedly connected to the four groups of threaded columns 107, and the upper pad 103 is detachably connected to the bottom plate 101 through the four groups of connecting ear plates 106, the threaded columns 107 and the locking nuts 108;

[0027] The heating component 200 includes an electric heating tube 201. A primary groove is formed on the top of the lower pad 102 and matches the lower half of the electric heating tube 201. A secondary groove is formed on the bottom of the upper pad 103 and matches the upper half of the electric heating tube 201. The primary groove and the secondary groove are combined to form a chamber that matches the electric heating tube 201. The chamber is connected to the outside. The electric heating tube 201 is embedded in the chamber. A control module 202 is provided on the top of the base plate 101 for controlling the operation of the electric heating tube 201 when the outside temperature is lower than a set value. The electric heating tube 201 is electrically connected to the control module 202. The control module 202 is also electrically connected to a temperature sensor 203.

[0028] Among them, the top of the upper pad 103 is also fixedly connected to a limiting ring 105, which is sleeved on the outside of the rubber block 104. The limiting ring 105 is used to limit the rubber block 104 to prevent the rubber block 104 from shifting during use. The inner diameter of the limiting ring 105 matches the diameter of the rubber block 104 to ensure that the rubber block 104 remains stable. The upper pad 103 and the limiting ring 105 are integrally formed, and the integral forming is conducive to ensuring the structural strength.

The threaded column 107 and the locking nut 108 are both made of stainless steel, which is corrosion-resistant.

[0030] Working principle: The temperature sensor 203 monitors the outside temperature in real time. When the outside temperature is lower than the set value, the control module 202 controls the electric heating tube 201 to operate, the electric heating tube 201 heats the upper pad 103, and the upper pad 103 heats the rubber block 104 to avoid the embrittlement of the rubber block 104 due to too low temperature;

[0031] like Figure 2 As shown, the four sets of locking nuts 108 can be removed by screwing outward, and the upper pad 103 can be lifted up to remove it. After the upper pad 103 is removed, the electric heating pipe 201, the control module 202 and the temperature sensor 203 can be directly removed, which is convenient for maintenance of the device.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
