The invention discloses a vertical shaft safety protection net laying device and a using method thereof.The vertical shaft safety protection net laying device comprises a support, an unfolding and folding assembly is arranged on the support, one end of the unfolding and folding assembly penetrates through the support to be connected with a supporting panel, a plurality of splicing type supporting pipes are further connected between the supporting panel and the support, and one ends of the splicing type supporting pipes are fixedly installed on the supporting panel; the other end is slidably mounted on the bracket; four protective net unfolding and folding assemblies are arranged on the support, a safety protective net is installed in the protective net unfolding and folding assemblies, one end of the safety protective net penetrates out of the protective net unfolding and folding assemblies to be connected with a clamping assembly, and the clamping assembly is detachably installed on the supporting panel; tensioning assemblies are installed among the multiple spliced supporting pipes and used for improving the tensioning degree of the safety protection net. According to the device, the safety protection net is laid from top to bottom, operation is easy, safety is good, laying efficiency is high, and the laid safety protection net is good in tensioning performance and high in practicability.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a device for laying safety nets for shafts and a method for using the same. Background technique [0002] The elevator shaft is the hoistway where the elevator is installed. The size of the hoistway is determined according to the selection of the elevator. The elevator track and counterweight track are installed on the shaft wall, and the elevator door is installed in the reserved door. There is an elevator machine room on the top of the hoistway. When decorating and installing the internal accessories, it is necessary to set up a safety net in the elevator shaft to prevent debris from falling from the top of the elevator shaft. The current safety net laying method is from bottom to top, which requires multiple people to operate. However, the space in the elevator shaft is small, which is inconvenient for multiple people to operate. Single or double operation takes ...
