Description

Test device for net bag hanging Technical Field The utility model relates to the technical field of sling testing, in particular to a testing device for net bag sling. Background The ecological nylon net bag shore protection technology is also called as green grid and honeycomb grid stone cage protection technology, and is a technology for cutting mechanically woven hexagonal nylon net sheets, assembling the net bags, filling fillers such as stone blocks and the like, hoisting the net bags into water bodies through a crane, and using the net bags as a shore protection or slope protection. The quality of stone needs to be controlled when the net bag is lifted, the stone is too much to possibly lead to the net bag to be damaged, the stone falls off, potential safety hazards or uncontrollable quality are caused, and the weight of the nylon net bag cannot meet the construction requirement when the stone is too little, so that the net bag needs to be subjected to a lifting weight performance test before construction. The existing sling performance test is generally selected to be tested on site, and although the on-site test can test the nylon net bag, the nylon net bag is required to be rented, assembled and disassembled manually, so that the method is time-consuming and labor-consuming, complex in work, high in test cost, low in test efficiency and poor in test effect and economy. Therefore, it is necessary to provide a test device for net bag hanging to solve the above technical problems.
