[0043] Working principle:

[0044] The utility model discloses a kind of warning net storage frame, by setting the lifting conveying frame that can be relatively fixed transmission frame displacement, utilize the warning net to be conveyed around in lifting conveying frame and fixed transmission frame, the spacing between fixed transmission frame and lifting conveying frame is adjusted by the transmission tension of warning net, to further adapt to the length of the accommodation of warning net under different tension Control. By the warning net is sequentially threaded and wound between fixed transmission frame and lifting conveying frame and the spacing of transmission roller one and transmission roller two, the storage of warning net under different lengths is realized. The spacing between lifting conveying frame and fixed transmission frame is larger, accommodate more warning net, provide replacement time while avoiding the warning net on rack to fall to ground, cause pollution.

[0045] When the winding machine winds at one end of the warning net, the warning net will be relatively tight, and the warning net will also be tight. When the winding machine is wound, the winding shaft needs to be replaced, and the winding of the warning net is released. At this time, the production end of the warning net will continue to produce, the tension of the warning net between the lifting conveyor and the fixed conveyor will be loose, the distance between the lifting conveyor and the fixed conveyor will be larger, and more warning nets will be accommodated. The replacement time of the winding shaft avoids the warning net on the rack from falling to the ground and causing pollution.

[0046] In example two, the lifting conveyor is also movably arranged in the steering hole of the rack through the counterweight chain, and a counterweight block is connected to the other end of the counterweight chain. By adjusting the counterweight chain, the lifting of the lifting conveyor during winding and unwinding of the warning net is adjusted.

[0047] In example three, the warning net is also arranged through the opening and closing type locking clamp, and the warning net is movably arranged through the conveying gap between the opening and closing type clamping plates by releasing the opening and closing type locking clamp. The warning net arranged between the opening and closing type clamping plates is clamped by the limiting clamp pressing one side of the opening and closing type clamping plate through the pressing roller.

[0048] In example four, an isolation platform is also provided to prevent the warning net on the lifting conveyor from falling and contacting the ground.

[0049] The warning net machine in the utility model is sequentially wound on the conveying roller one and the conveying roller two arranged at intervals between the fixed conveying frame and the lifting conveying frame. When the winding machine works normally, the lower frame is located above the rack. When the winding machine stops winding after a full winding, the lower frame descends under the action of gravity, stores the warning net produced by the warning net machine, and releases the stored warning net after the full winding is replaced and the empty winding is replaced to start winding again. Thus, the net storage function is realized.
