[0027] In addition to the above, it is still necessary to emphasize that the reference to "embodiment" in this article means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] like Figures 1 to 3 As shown, the embodiment of the present application provides an anti-falling device for an attached lifting scaffold, the anti-falling device for an attached lifting scaffold comprises a rigid support frame 1, an attached support frame 2 and an anti-falling assembly 3, the rigid support frame 1 is fixedly connected to the engineering building, the attached support frame 2 is fixed to the rigid support frame 1, the anti-falling assembly 3 is installed on the attached support frame 2 and extends into the guide rail 10 of the scaffold 100 to prevent the scaffold 100 from falling rapidly. A plurality of anti-falling cross bars 20 are arranged at intervals on the guide rail 10 of the attached lifting scaffold 100, and the anti-falling assembly 3 extends into the guide rail 10 and is located below the anti-falling cross bar 20.

[0029] The attached lifting scaffolding anti-falling device of the present application is used to realize the anti-falling protection of the attached lifting scaffolding 100 on floors with larger floor heights. For example, the attached lifting scaffolding anti-falling device in the present embodiment is installed in the refuge floor of an engineering building, wherein the standard floor height of the engineering building is 2.95 meters and the floor height of the refuge floor is 5.4 meters.

[0030] In some embodiments, the rigid support frame 1 includes a steel column support 11 and a shear rod 12, wherein the steel column support 11 is fixed to the engineering building, one end of the shear rod 12 is connected to the steel column support 11, and the other end is connected to the engineering building; the attachment bracket 2 is fixed to the steel column support 11. Figure 1 As shown, the steel column support 11 is fixed to the engineering building by through-wall bolts, one end of the shear rod 12 is connected to the steel column support 11 by bolts, and the other end is connected to the engineering building by through-wall bolts. The rigid support frame 1 provides stable support and tension to the attachment bracket 2 and the anti-fall assembly 3, so that the anti-fall protection of the attachment lifting scaffold 100 can be achieved on floors with a large floor height.

[0031] like Figures 1 to 3 As shown, the steel column support 11 has a plurality of connectors 111 for installing the shear rods 12. According to different engineering building structures, the shear rods 12 are connected to connectors 111 at different positions of the steel column support 11. Specifically, a plurality of connectors 111 for installing the shear rods 12 are provided on the vertical columns in the steel column support 11.

[0032] See also Figure 2 and Figure 3 In some embodiments, the rigid support frame 1 further includes a heightening seat 13 , and the steel column support 11 is fixed to the engineering building through the heightening seat 13 .

[0033] like Figure 4 and 5As shown, in some embodiments, the anti-falling assembly 3 includes an anti-falling pendulum block 31, an anti-falling pendulum pin 32, an anti-falling baffle 33 and a limit baffle 34. The anti-falling pendulum block 31 and the anti-falling pendulum pin 32 are rotatably mounted on the attachment bracket 2 through a pin shaft, and the anti-falling baffle 33 and the limit baffle 34 are fixed on the attachment bracket 2. The anti-falling baffle 33 is fixed on the top of the anti-falling pendulum block 31 by welding or riveting. When the attachment lifting scaffold 100 moves downward to drive the anti-falling pendulum block 31 to rotate to a horizontal position, the anti-falling baffle 33 contacts the anti-falling pendulum block 31 and blocks the anti-falling pendulum block 31 from continuing to rotate, so that the attachment lifting scaffold 100 can be prevented from falling by the anti-falling pendulum block 31 and the anti-falling baffle 33 when falling. The limit baffle 34 is fixed above the anti-falling pendulum block 31 by welding or riveting. When the attached lifting scaffold 100 moves upward, the limit baffle 34 is used to prevent the anti-falling pendulum block 31 from losing its position and failing to reset in time due to excessive rotation.

[0034] like Figure 6 As shown, in some embodiments, the anti-falling pendulum block 31 is provided with a mounting groove 311, the anti-falling pendulum pin 32 is rotatably mounted in the mounting groove 311, and a reset torsion spring is further provided between the anti-falling pendulum block 31 and the anti-falling pendulum pin 32. The reset torsion spring is used to quickly reset the anti-falling pendulum pin 32.

[0035] See also Figure 4 , a plurality of anti-falling cross bars 20 are arranged at intervals on the guide rail 10 of the attached lifting scaffold 100. Initially, the anti-falling pendulum pin 32 extends into the guide rail 10 and is located below the anti-falling cross bar 20, and the anti-falling pendulum block 31 is located outside the guide rail 10. The anti-falling cross bars 20 on the guide rail 10 are evenly distributed. When descending, the anti-falling cross bars 20 contact the anti-falling pendulum pin 32 of the anti-falling assembly 3 to drive the anti-falling pendulum pin 32 to rotate, and the anti-falling pendulum block 31 also rotates to a horizontal position and extends into the guide rail 10. Then the guide rail 10 continues to descend, and there is no squeezing force after passing the anti-falling pendulum pin 32. The anti-falling assembly 3 returns to its initial position under the action of gravity. When descending normally, the anti-falling pendulum block 31 that rotates to a horizontal position before the next anti-falling cross bar 20 contacts the anti-falling pendulum pin 32 can return to its initial position, and the frame can continue to move downward. When a fall occurs, under the action of gravity, the descent speed of the entire frame increases rapidly, which is much higher than the normal descent speed. The anti-fall pendulum block 31 that has rotated to the horizontal position has not yet recovered and is still almost in a horizontal state. At this time, the anti-fall cross bar 20 on the guide rail 10 hits the anti-fall pendulum block 31, and the anti-fall baffle 33 prevents the anti-fall pendulum block 31 from continuing to rotate. The guide rail 10 cannot continue to fall downward under the obstruction of the anti-fall pendulum block 31, and the fall is quickly braked, thereby protecting the safety of the frame and personnel.

[0036] like Figure 4 and 5As shown, in some embodiments, the attached lifting scaffold anti-falling device also includes a unloading component 4, and the unloading component 4 includes a support head 41, a screw 42 and a sleeve 43, the support head 41 is connected to the screw 42, the screw 42 is connected to the sleeve 43, and the sleeve 43 is rotatably connected to the attached bracket 2. The unloading component 4 is rotatably connected to the attached bracket 2. It can be installed on the attached bracket 2 by welding a nut at one end of the sleeve 43, and then installing it on the attached bracket 2 after passing a bolt through the nut; the unloading component 4 can also be rotatably installed on the attached bracket 2 in a hinged manner. The support head 41 has a groove that matches the anti-falling crossbar 20, and the top support guide rail 10 is turned to page 6

[0037] The dynamic unloading component 4 is tilted to one side of the guide rail 10, and the screw 42 is turned to make the support head 41 rise and support the anti-falling cross bar 20 on the guide rail 10, so as to achieve the unloading effect.

[0038] like Figure 4 and 5 As shown, in some embodiments, the anti-falling device of the attached lifting scaffolding also includes an anti-overturning component 5, and the anti-overturning component 5 includes a guide wheel seat 51, a guide wheel shaft 52 and a guide wheel 53. The guide wheel seat 51 is fixed on the attached bracket 2, the guide wheel shaft 52 is fixed on the guide wheel seat 51, and the guide wheel 53 is sleeved on the guide wheel shaft 52. The guide rail 10 of the scaffolding is located between the guide wheel 53 and the attached bracket 2. The guide wheel seat 51 is installed on the attachment bracket 2 by bolts, and the guide wheel 53 is welded and installed on the guide wheel seat 51 through the guide wheel shaft 52. The guide wheel 53 is fixed relative to the attachment bracket 2. The guide rail 10 of the scaffolding is located between the guide wheel 53 and the attachment bracket 2, which limits the movement space of the guide rail 10. After being constrained, it can only slide vertically, so that the vertical main frame connected to the guide rail 10 and the entire frame can only move in the vertical direction, thereby ensuring the stability of the use and lifting state of the attached lifting scaffolding 100 and will not cause overturning.

[0039] In some embodiments, the attachment bracket 2 includes a back plate 21, an anti-falling mounting seat 22 and an anti-overturning mounting plate 23, the back plate 21 is fixed on the rigid support frame 1, the anti-falling assembly 3 is mounted on the anti-falling mounting seat 22, the unloading component 4 is mounted on the anti-falling mounting seat 22, and the anti-overturning component 5 is mounted on the anti-overturning mounting plate 23. Specifically, the anti-falling mounting seat 22 has two anti-falling mounting plates arranged opposite to each other, and the anti-falling mounting plates are provided with two groups of mounting holes, wherein the upper group of mounting holes is used to install the unloading component 4, and the lower group of mounting holes is used to install the anti-falling pendulum block 31 and the anti-falling pendulum needle 32.

It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented.
