[0020] To make the objectives, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0021] As Figures 1 to 3As shown in the figure, a safety net for steel structure construction includes a safety net body 1, and also includes a retracting and deploying assembly for retracting and deploying the safety net body 1. The retracting and deploying assembly includes a U-shaped frame 201, on which a retracting shaft 202 is rotatably connected. The safety net body 1 is wound around the retracting shaft 202. An installation assembly for assisting installation is provided at the front end of the safety net body 1 and on the U-shaped frame 201. A limiting assembly for limiting the safety net body 1 after retracting and deploying is provided between the retracting shaft 202 and the U-shaped frame 201.

[0022] During the construction process of the steel structure, when using the safety net for protection operations, through the mutual cooperation of the retracting and deploying assembly, the installation assembly and the limiting assembly, the wound safety net body 1 is released or retracted, and the use length of the safety net body 1 is adjusted, so that the safety net body 1 can adapt to different protection intervals, ensuring the flexibility of the safety net body 1 during the protection process, facilitating the operation and use of the safety net, and after the retracting and deploying adjustment of the safety net is completed, the retracting shaft 202 is limited, facilitating the stable protection and use of the safety net body 1 after the retracting and deploying adjustment.

[0023] Two groups of limiting assemblies are symmetrically arranged on both sides of the U-shaped frame 201; through the two groups of limiting assemblies, the limiting effect is ensured.

[0024] The limiting assembly includes an installation sleeve 401 provided on one side of the U-shaped frame 201. A plurality of limiting rods 402 are fixed on the side of the installation sleeve 401 close to the U-shaped frame 201. Each group of limiting rods 402 is arranged in an annular array. A limiting hole 403 for inserting and limiting the limiting rods 402 is opened on one side of the U-shaped frame 201. The installation sleeve 401 and the retracting shaft 202 are connected through a transmission assembly; after the use length of the safety net body 1 is adjusted, the pulling of the installation sleeve 401 is released, and through the elastic force of the compression spring 602, the installation sleeve 401 is pushed to reset. During the reset process of the installation sleeve 401, each group of limiting rods 402 is respectively inserted into the inside of each group of limiting holes 403. Through the insertion and limiting effect of the limiting rods 402 and the limiting holes 403, the installation sleeve 401, the spline shaft 501 and the retracting shaft 202 are limited.

[0025] The transmission assembly includes a spline shaft 501 fixed at one end of the retracting shaft 202. A spline groove 502 is opened on the inner side of the installation sleeve 401. The spline shaft 501 and the spline groove 502 are matched with each other. A pushing assembly for elastically pushing the installation sleeve 401 is provided at one end of the spline shaft 501; through the transmission of the spline shaft 501 and the spline groove 502, it is convenient for the installation sleeve 401 and the retracting shaft 202 to be limited and rotate automatically in synchronization.

[0026] The driving component includes a baffle plate 601 fixed to the end of the spline shaft 501. An extrusion spring 602 is sleeved outside the spline shaft 501, and both ends of the extrusion spring 602 are abutted against the baffle plate 601 and the mounting sleeve 401 respectively. During the process of pulling the mounting sleeve 401, due to the abutment of the baffle plate 601 and the extrusion of the mounting sleeve 401, the extrusion spring 602 is deformed under force to generate elastic force. Through the elastic force of the extrusion spring 602, it is convenient to assist the reset movement of the mounting sleeve 401 after being stressed.

[0027] The installation component includes a strip plate 301 fixed to the front end of the protective net body 1. Multiple groups of hooks 302 for auxiliary hanging installation are installed on the strip plate 301 and the U-shaped frame 201. Through the multiple groups of hooks 302 on the strip plate 301 and the U-shaped frame 201, it is convenient to install and connect the entire protective net.

[0028] During the construction process of the steel structure, when using the protective net for protection operations, the mounting sleeve 401 is pulled away from the U-shaped frame 201. During the pulling process, each group of limiting rods 402 are respectively pulled out from each group of limiting holes 403. Through the separation of the limiting rods 402 and the limiting holes 403, the mounting sleeve 401, the spline shaft 501 and the winding shaft 202 can rotate normally.

[0029] During the rotation of the winding shaft 202, the wound protective net body 1 is released or wound up to adjust the use length of the protective net body 1, so that the protective net body 1 can adapt to different protection distances, ensure the flexibility of the protective net body 1 during the protection process, and facilitate the operation and use of the protective net.

[0030] After the use length of the protective net body 1 is adjusted, the pulling of the mounting sleeve 401 is released. Through the elastic force of the extrusion spring 602, the mounting sleeve 401 is pushed to reset. During the reset process of the mounting sleeve 401, each group of limiting rods 402 are respectively inserted into the interior of each group of limiting holes 403. Through the insertion and limiting effect of the limiting rods 402 and the limiting holes 403, the mounting sleeve 401, the spline shaft 501 and the winding shaft 202 are limited, so that the protective net body 1 after the retraction and extension adjustment can be stably used for protection. And after the winding shaft 202 is limited, the front side of the protective net body 1 and the U-shaped frame 201 are hung and connected to the corresponding positions through each group of hooks 302 to complete the installation and connection of the entire protective net.
