[0022] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] A coupling replacement rack comprises an inclined guide rail 3 and a frame supporting the guide rail 3, wherein the guide rail 3 is provided with a sliding seat 7, and the sliding seat 7 is provided with a coupling fixture; and the frame is provided with a lifting device for driving the sliding seat 7 to move up and down along the guide rail 3.

[0025] Due to the above structure, after the coupling 4 is fixed on the sliding seat 7 by the coupling clamp, the lifting device can conveniently drive the coupling 4 to move up and down in an inclined manner, so as to facilitate the docking of the coupling 4 and the shaft to be connected.

[0026] The frame includes a top plate 2, a bottom plate 9 and a guide rail mounting plate 15, wherein the top plate 2 and the bottom plate 9 are arranged in parallel, and the guide rail mounting plate 15 is arranged obliquely between the top plate 2 and the bottom plate 9, and the upper end of the guide rail mounting plate 15 is connected to the top plate 2, and the lower end is connected to the bottom plate 9; the guide rail 3 is arranged on the guide rail mounting plate 15.

[0027] Due to the above structure, the top plate 2, the bottom plate 9 and the guide rail mounting plate 15 form a "Z"-shaped structure.
