Detailed Description

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

the utility model relates to a falling protection device for scaffold, as shown in figure 1, falling protection device includes the installation pipe 21 of scaffold, support tube 11, connecting pipe 12, first anchor clamps 15, second anchor clamps 16, slide fastener 13, be provided with first locking firmware 18 and second locking firmware 19 on the support 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 be fixed on scaffold installation pipe 21 for fixed falling protection device. 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 and the connecting tube 12 are fixedly connected through a high-strength bolt to form a stable triangular structure. A step is provided on the support tube 11 between the second stop fastener 19 and the slide fastener 13 for carrying fallen droppings. 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.
