[0031] Reference Figs. 1-3 The embodiment provides a guide rail anti-falling protection device, which is applied to a flexible guide rail 1 and comprises a quick-release mounting mechanism 2 and a locking mechanism 3.

[0032] The quick-release mounting mechanism 2 is in sliding connection with the flexible guide rail 1.

[0033] The locking mechanism 3 comprises two locking blocks 31, two L-shaped connecting blocks 32 and two eccentric wheels 35.

[0034] One side of the two locking blocks 31 is arranged close to the flexible guide rail 1, and the other side is connected with one end of the L-shaped connecting block 32.

[0035] The corner 321 of the two L-shaped connecting blocks 32 is provided with a rotating shaft 34, both ends of the rotating shaft 34 are rotatably connected with a fixing seat 33, and the other end of the two L-shaped connecting blocks 32 is provided with an opening, and the opening is rotatably connected with the eccentric wheel 35 through the eccentric shaft 36 at both ends.

[0036] Further, the outer sides of the two eccentric wheels 35 are respectively connected with connecting blocks two 37 for passing safety ropes 38.

[0037] It should be noted that in the normal state, the connecting block two 37 is horizontally placed, and the plane formed by the eccentric shaft 36 and the rotating shaft 34 in this state is parallel to the plane where the sliding plate 21 is located; and the eccentric shaft 36 is arranged close to the side of the L-shaped connecting block 32.

[0038] Specifically, the quick release mounting mechanism 2 includes two sliding plates 21 and two screws 22; wherein,

[0039] Two sliding plates 21 are respectively provided with semicircular grooves 211 close to one side of the flexible guide rail 1, and both sides of the two sliding plates 21 are provided with threaded holes 212;

[0040] Two screws 22 pass through the threaded holes 212 of the two sliding plates 21 in turn, and are fixed by hex nuts 23, and a flat washer is further arranged between the hex nut 23 and the sliding plate 21.

[0041] In order to better fit the shape of the flexible guide rail 1, provide larger contact area and more uniform clamping force, in the embodiment, the two locking blocks 31 close to one side of the flexible guide rail 1 are arc-shaped.

[0042] Further, the arc-shaped side of the two locking blocks 31 is further provided with a reinforced non-slip pad 39.

[0043] It should be noted that the reinforced non-slip pad 39 can be a sawtooth-shaped protruding piece, which facilitates the insertion of the sawtooth-shaped protruding piece into the flexible guide rail 1 when the locking block 31 contacts the flexible guide rail 1, thereby achieving higher stability.

[0044] In order to further improve the stability of the device, in the embodiment, the two sliding plates 21 are further respectively provided with limiting grooves 213 corresponding to the movement track of the eccentric wheel 35.

[0045] Working principle: in use, first, two sliding plates 21 are installed on the outer periphery of the flexible guide rail 1 through screws 22, the safety rope 38 worn by the high-altitude worker is fixed on the rope passing hole 371 of the connecting block two 37, when the high-altitude worker slowly rises, the safety rope 38 moves upward, the eccentric wheel 35 moves slightly outward under the action of the connecting block two 37, and its eccentric shaft 36 slightly deviates downward, so that the top position of the L-shaped connecting block 32 also slightly deviates outward, thereby driving the locking block 31 to slightly deviate outward, which can be ignored when the high-altitude worker slowly rises; however, when the high-altitude worker loses balance, the high-altitude worker will quickly descend, at this time, the sliding plate 21 will also maintain the original movement state and position due to inertia, but the eccentric wheel 35 will quickly deviate inward due to the force of the safety rope 38, and its eccentric shaft 36 will be lifted upward, so that the top position of the L-shaped connecting block 32 quickly deviates inward, thereby driving a pair of locking blocks 31 to quickly deviate inward and then being locked on the flexible guide rail 1, achieving the anti-falling function.

[0046] In summary, the guide rail anti-falling protection device improves the convenience of use while significantly enhancing the stability and safety of the device through its unique structural design, and can effectively meet the high requirements of anti-falling devices in high-altitude work.

[0047] The above is only the preferred embodiment of the present application, it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, can make a number of improvements and deformation, these improvements and deformation should also be considered as the protection scope of the present application.
