[0021] It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0022] In order to make the content of the present utility model more clearly understood, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model.

[0023] As Figures 1 to 2As shown in the figure, a test frame for an electric roller includes a bottom plate 1. Two symmetrically arranged mounting brackets 2 are fixedly welded to the top of the bottom plate 1. An electric roller 3 is provided on the two mounting brackets 2. First bearing seats 16 are arranged at both ends of the electric roller 3. The first bearing seats 16 are fixedly connected to the mounting brackets 2 by bolts. Removing the bolts facilitates the replacement of different electric rollers 3.

[0024] A bracket 4 is fixedly welded to the bottom plate 1. An oil cylinder 5 is fixedly installed on the bracket 4. A connecting component 6 is arranged at one end of the oil cylinder 5 away from the bracket 4. The connecting component 6 includes a cylinder body 10. A pressure sensor 13 is arranged between the piston rod of the oil cylinder 5 and the cylinder body 10. The pressure sensor 13 is used to test the bearing capacity of the electric roller 3. A number of disc springs 11 are arranged in the cylinder body 10. Every two adjacent disc springs 11 are symmetrically arranged. A connecting rod 12 is slidably connected in the cylinder body 10.
