Description

Technical Field

[0001] The utility model relates to the field of safety vertical nets, and more specifically, to a safety vertical net stretching and fixing device. Background Art

[0002] Safety nets are protective nets set up under or beside high-altitude construction equipment during installation or skill performances to prevent accidents caused by falling people or objects.

[0003] After searching, the existing patent (publication number: CN211396710U) discloses a reinforced safety vertical net, including a net body and a support column. The middle part of the net body is woven and connected with a reinforcing rope, and the four ends of the net body are woven and connected with side ropes. The left and right ends of the side ropes are evenly woven and connected with tethers, and the other end of the tethers is tied to the support column. The auxiliary support device of the utility model is composed of a connecting seat, an adjusting bolt, a supporting foot and a fixing plate. The connecting seat is fixed to the support rod by a fixing plate bolt, and the adjusting bolt is turned by hand to loosen it. Then the support frame grasps the supporting foot and rotates in the connecting seat with the adjusting bolt as the origin to adjust the angle with the support column, so that the support frame contacts the ground to support the middle and upper part of the support rod to prevent it from tilting under force. The beneficial effect is that when the object falls and is covered by the safety vertical net, the upper part is supported by the auxiliary support device, so that the bottom plate bolts of the support column will not be lifted up, so that the safety vertical net is firmly protected. The inventor found that the prior art has the following problems in the process of realizing the utility model:

[0004] The existing safety vertical net is mainly used for the purpose of safety protection at the construction site, which can effectively prevent the free fall of various objects at the construction site, thereby producing a buffering effect. When installing, the worker puts one end of the safety net in a suitable position and ties it firmly with a wire, and then manually stretches and fixes the safety net holes along the external frame. During the stretching process, the worker needs to stretch the safety dense mesh net with one hand and tie it with the other hand during the external frame construction. There are safety hazards during construction. The wire binding and the steel pipe are easily rusted and easy to fall off after a long time of friction. Therefore, when fixing the safety net, a fixing mechanism is required to facilitate fast and safe fixing;

[0005] Therefore, in view of the above problems, a safety vertical net stretching and fixing device is proposed. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a safety vertical net stretching and fixing device to solve the problems raised in the above-mentioned background technology.
