Detailed Description

The following further describes the embodiments of the present invention with reference to the attached drawings:

the utility model relates to a double-barrelled anti-falling device for scaffold, as shown in figure 1, anti-falling device includes installation pipe 21, stay tube 11, connecting pipe 12, first anchor clamps 15, second anchor clamps 16, slide fastener 13 and additional reinforced pipe 14 of scaffold, be provided with first locking firmware 18 and second locking firmware 19 on the stay tube 11, slide fastener 13 can slide between first locking firmware 18 and second locking firmware 19, first anchor clamps 15 and second anchor clamps 16 are used for the installation to fix on scaffold installation pipe 21 for fixed anti-falling device. The additional reinforcing pipe 14 is arranged inside the supporting pipe 11, at least two through holes 14a are arranged on the additional reinforcing pipe 14, the supporting pipe 11 is correspondingly provided with through holes at corresponding positions, and the additional reinforcing pipe 14 is fixedly connected with the supporting pipe 11 through bolts; during the use, slide fastener 13 slides to first locking firmware 18 and with first locking firmware 18 rigid coupling, first anchor clamps 15 pass through high strength bolt and stay tube 11 fixed connection, second anchor clamps 16 pass through high strength bolt and connecting pipe 12 fixed connection, can improve anti-falling device's stability. The supporting tube 11 is fixedly connected with the connecting tube 12 through a high-strength bolt, and a pedal is arranged on the supporting tube 11 between the second stop fastener 19 and the sliding fastener 13 and used for bearing fallen falling objects. When the device is stored, the sliding fastener 13 slides to the second stopping fastener 19 and is fixedly connected with the second stopping fastener 19, and the connecting pipe 12 is connected with the sliding fastener 13 through a bolt, so that the connecting pipe and the supporting pipe can be fixed together in the length direction, and the device is convenient to store and transport in a set.

The additional reinforcing tubes 14 are located within the support tube 11 before and after the corresponding first stop fasteners 18. Preferably, the length of the additional reinforcing tube 14 may be designed to be smaller than the length of the support tube 11, in order to save material. By adding the double tube support of the reinforcing tube 14 and the support tube 11, the load bearing of the connection of the installation tube and the support tube for higher loads can be increased.

The supporting pipe has a certain inclination angle during installation, the inclination angle of the supporting pipe relative to the horizontal line is preferably 10 degrees, the length and the inclination angle of the connecting pipe are designed to be adaptive to the length and the inclination angle of the supporting pipe, and a stable triangular structure is formed.
