[0039] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0040] This application discloses a rolling guide shoe roller life testing device. (Refer to...) Figure 1 and Figure 2 The rolling guide shoe roller life test device includes a bracket 1, a rotating wheel 2, a connecting frame 3, and a load-bearing frame 4.

[0041] like Figure 1 and Figure 2 As shown, the bracket 1 is fixedly installed on a horizontal plane such as the ground, and the bracket 1 can provide a stable installation platform for the connecting frame 3 and the rotating wheel 2; for example, the bracket 1 is a metal frame.

[0042] In this embodiment, the roller 2 is rotatably connected to the bracket 1 via a rotating seat or other structure or device. The roller 2 is vertically disposed at the lower part of the bracket 1. A first driving member 5 is disposed on one side of the roller 2. The output end of the first driving member 5 is detachably connected to the roller 2, and the fixed end of the first driving member 5 is fixedly connected to the bracket 1.

[0049] In the embodiment of the application, the sliding groove 11 is provided with a metal sheet 13, one end of the metal sheet 13 is fixedly connected with the inner wall of the sliding groove 11, the other end of the metal sheet 13 is fixedly connected with the sliding block 12, the metal sheet 13 is arranged in an arc shape, and is used for limiting the position of the sliding block 12; the elastic limiting function of the metal sheet 13 can prevent the sliding block 12 from moving excessively in the sliding groove 11, and damage to the connecting frame 3 or the roller 8 caused by the sliding block 12 exceeding a predetermined range can be avoided.

[0050] For example, the metal sheet 13 is a spring steel sheet, the elastic characteristics of the spring steel sheet can adapt to impact and vibration in a dynamic working condition, and the reliability of simulating elevator running can be ensured.

[0051] As shown in Figure 4 The side walls on both sides of the sliding groove 11 are provided with L-shaped grooves 14, the two L-shaped grooves 14 are symmetrically arranged, the two L-shaped grooves 14 are used for placing a metal rod 15 and limiting the positions of two ends of the metal rod 15, and the metal rod 15 is used for abutting against the metal sheet 13 to limit the deformation of the metal sheet 13, thereby limiting the movement of the sliding block 12 and finally limiting the movement of the connecting frame 3.
