[0013] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1 and attached Figure 2 As shown, a device for replacing roller bearings of a cement roller press comprises a moving platform 1, characterized in that universal moving wheels 2 are fixedly connected to the four lower corners of the moving platform 1; a push handle 3 is fixedly connected to the left portion of the moving platform 1; a lifting platform 4 is arranged on the upper side of the moving platform 1, and electric push rods 5 are longitudinally fixedly connected to the four upper corners of the lifting platform 4, wherein the lower ends of the output rods of the electric push rods 5 pass through the interior of the lifting platform 4 respectively; the lower ends of the output rods of the electric push rods 5 are fixedly connected to the four upper corners of the moving platform 1 respectively.

[0014] One of the devices for replacing roller bearings of a cement roller press also includes a position limiting and lifting assembly 6, and the position limiting and lifting assembly 6 is fixedly connected to the upper middle part of the lifting platform 4, which is conducive to achieving the effect of fixing the bearing.

[0015] Among them, the limited lifting component 6 includes a lifting platform 61, and a V-shaped limiting groove 62 is opened on the middle and upper side of the inner part of the lifting platform 61; the middle and upper sides of the front and rear parts of the lifting platform 61 are respectively fixedly connected with U-shaped tie plates 63 from left to right; the upper side of the lifting platform 61 is sequentially provided with fastening belts 64 from left to right, and one end of the fastening belt 64 is respectively tied to the inner side of the U-shaped tie plate 63 on the front side, and the other end is respectively tied to the inner side of the U-shaped tie plate 63 on the rear side.
