[0002] In the existing field of cargo platform technology, safety calipers are installed on both sides of the cargo platform, which are clamped between the column guide rails for vertical up and down movement. When the steel wire rope of the cargo platform is worn and broken, the calipers clamp the column guide rails tightly, and the cargo platform stops running to act as an emergency safety brake.

[0003] The T-shaped guide rail on the column is welded. Due to the high height of the column, the guide rail is deformed after being welded in sections. The safety caliper is easy to accidentally clamp the rail on the column during the up and down movement of the cargo platform. In view of this problem, the present invention provides a safety caliper device with a floating guide wheel. Summary of the invention

[0020] 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 used to limit the present invention.

[0021] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a clamp floating roller device, including a safety clamp 2, a guide wheel assembly 3 and a clamp floating device 5. The safety clamp 2 runs along a T-shaped guide rail 1. The clamp floating device 5 is connected to the safety clamp 2. The clamp floating device 5 solves the problem of the safety clamp 2 getting stuck by swinging the rotating block 501 left and right.

[0022] like Figure 5 and Figure 6 As shown, the clamp floating device 5 includes a rotating block 501, a support block 502, a cover plate 503 and a gasket 504; the support block 502 is fixedly connected to the cargo platform side plate 6 by fasteners; a waist hole is provided on the support block 502, and a first boss is provided on the rotating block 501, and the first boss extends into the waist hole; a second boss is provided on the cover plate 503, and the second boss is flush with the gasket 504, and the second boss is fixedly connected to the first boss through a connecting piece; because the first boss extends into the waist hole and exceeds the support block 502 by a certain gap, the rotating block 501 can rotate left and right on the support block 502.

[0023] The upper and lower ends of the slewing block 501 are respectively provided with guide wheel assemblies 3, and the guide wheel assemblies 3 run along the T-shaped guide rail to play an auxiliary guiding role for the caliper.

[0024] like Figure 3 and Figure 4 As shown, the guide wheel assembly 3 includes a bearing seat 301, a left lever 302 and a right lever 303, and guide wheels 304 are respectively arranged on the left lever 302 and the right lever 303. The guide wheel 304 is in the form of rubber coating, which is low-noise during the walking process. Compared with steel wheels, it does not produce iron filings to contaminate the goods. The middle parts of the left lever 303 and the right lever 304 are respectively installed on the bearing seat 301 through the locking shaft 305 and the bearing 306, and the left lever 303 and the right lever 304 are respectively installed on the left and right sides of the bearing seat 301. A tightening spring 307 is provided in the bottom hole of the bearing seat 301. The tightening spring 307 is located on the inner side of the left lever 302 and the right lever 303, and is tightened to the inner side of the bearing seat 301 through the tightening screw.

[0025] In a specific embodiment, the slewing block 501 is connected to the safety clamp 2 via fasteners, and the fasteners may be hexagon socket head screws and standard spring washers.

[0026] In a specific embodiment, a caliper pad 4 is provided between the slewing block 501 and the safety clamp 2 .

[0027] In a specific embodiment, the gasket 504 is made of polytetrafluoroethylene.

[0028] Working method: When the cargo platform moves up and down on the column, the guide wheel 304 first runs along the T-shaped guide rail 1 to assist the guide of the clamp. The T-shaped guide rail 1 on the column is a welding process. Due to the high height of the column, the guide rail has deformation after the segmented welding is completed, which will then jam the safety clamp 2. The guide wheels 304 assembled on the upper and lower parts of the slewing block 501 can have a gap for swinging left and right when running up and down along the arc of the T-shaped guide rail 1, thereby solving the problem of the safety clamp 2.

[0029] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
