The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

Examples

As shown in fig. 1 to 3, the present embodiment provides a fall protection device for a translation or lifting device, comprising: translation track 1 and install running gear 2 on translation track 1, translation track 1 is I shape, and translation track 1's both sides are provided with the mounting groove that is used for installing running gear 2 promptly, and the mounting groove sets up along translation track 1.

The walking assemblies 2 are two groups in total, the two groups of walking assemblies 2 are respectively installed at one side installation groove of the translation track 1, each group of walking assemblies 2 comprises a main walking assembly and a standby walking assembly, and the main walking assembly comprises a walking plate 202, a first walking wheel 204 and a second walking wheel 205. The spare running assembly comprises a translation fence 201, a connection plate 203, a third running wheel 206 and a fourth running wheel 207. The translation guard plate 201 is in an isosceles trapezoid shape, and the translation guard plate 201 is in arc transition with equal angles. The walking board 202 is rectangular in shape, and the walking board 202 has an arc transition. The walking board 202 and the translation guard board 201 are connected and fixed through a connecting board 203. The walking plate 202 and the translation guard plate 201 are fixed with the connecting plate 203 through screws. A first connecting rod 3 is connected between the walking plates 202 in the two groups of walking assemblies 2, the walking plates 202 are fixedly connected through the first connecting rod 3, and the anti-falling device 6 is arranged on the first connecting rod 3 (shown in figure 1); a second connecting rod 4 is connected between the translation guard plates 201 in the two groups of walking assemblies 2, the translation guard plates 201 are fixedly connected through the second connecting rod 4, and the electric hoist 5 is installed on the second connecting rod 4 (as shown in fig. 1); the first traveling wheel 204 and the second traveling wheel 205 are rotatably connected with one side of the traveling plate 202 close to the translation track 1, and the first traveling wheel 204 and the second traveling wheel 205 are positioned in the mounting groove.
