[0003] In order to avoid injuries caused by falling objects on construction sites, it is necessary to use a building safety net for protection. For example, the prior art Chinese patent announcement number "CN216380666U" discloses a building safety net for construction, including a base, a fixing mechanism and a winding mechanism are arranged at the top of the base, the fixing mechanism and the winding mechanism are located on both sides of the top of the base, a slide groove is arranged in the inner cavity of the base, the winding mechanism is slidably connected with the slide groove, and a positioning hole is arranged on the side wall of the base. In the utility model, firstly, the movable column and the sliding block in the winding mechanism are fixedly connected, then a slide groove is arranged in the inner cavity of the base, and the sliding block is slidably connected with the slide groove, so that the movable column is slidably connected with the base through the sliding block, and then the second fixed seat arranged at the top of the movable column is rotatably connected with a rotating shaft, and the rotating shaft is caused to roll up the protective net by starting the driving motor, thereby reducing the labor intensity of manual labor, improving the winding efficiency, and facilitating movement and disassembly.

[0004] Some building safety nets are fixed by reinforcing ropes and snap-on components on the top. However, in actual operation, considering that similar devices are not convenient for storing the safety nets, installation and disassembly need to be done manually, which is time-consuming and labor-intensive and inconvenient for installing and fixing the safety nets, and has low practicality.

[0024] It is worth mentioning that the winding roller 4 is provided for winding up the safety net 8, and the guide roller 5 is used to guide and pull the safety net 8, and cooperate with the winding roller 4 to unfold and flatten the safety net 8 for protection, so as to achieve the effect of simultaneously unfolding or winding up the safety net 8, avoiding manual operation and being convenient and quick.

[0025] Further, the buffer member 3 includes a buffer cylinder 31 arranged at the bottom of the mounting frame 1, a vent hole 32 is opened at the bottom of the buffer cylinder 31, and a first spring 33 is fixedly connected to the inner bottom surface thereof, a piston rod 34 is slidably connected inside the buffer cylinder 31, one end of the piston rod 34 is fixedly installed at the bottom of the mounting frame 1, and the other end thereof is fixedly connected to the other end of the first spring 33, and a piston head is provided at one end of the piston rod 34 located in the buffer cylinder 31. The buffer member 3 can be used to prevent the impact caused by heavy objects falling on the safety net 8 from damaging the safety net 8 and the components in the mounting frame 1.

[0026] Furthermore, the driving assembly 6 includes a motor 61, the winding roller 4 is rotatably connected to the winding chamber 2, the motor 61 is fixedly mounted on the side of the mounting frame 1, and its axial end passes through the mounting frame 1 and is fixedly connected to the axial end of the winding roller 4, and the motor 61 is used to drive the winding roller 4 to rotate to reel up the safety net 8.

[0027] In more detail, the two sides of the mounting groove 21 are rotatably connected with a screw rod 62 and fixedly installed with a round rod 63, the guide roller 5 is threadedly connected to the screw rod 62 and slidably connected to the round rod 63, the shaft end of the motor 61 is fixedly installed with a driving bevel gear 64, the shaft end of the screw rod 62 is fixedly installed with a driven bevel gear 65, and the driving bevel gear 64 meshes and rotates with the driven bevel gear 65.

[0028] In more detail, Figure 2 As shown, under the action of the screw rod 62, the active bevel gear 64 and the driven bevel gear 65, the motor 61 can drive the winding roller 4 to rotate and at the same time drive the guide roller 5 to move, so that it cooperates with the winding roller 4 to spread or reel in the safety net 8, thereby facilitating the installation of the safety net.

[0029] In general, the clamping member 7 includes a protrusion 71, and a clamping groove 72 is formed at one end of the winding roller 4 and the guide roller 5 away from the motor 61. The two sides of the safety net 8 are inserted into the clamping groove 72 through the protrusion 71.

[0031] Finally, the bottom of the limiting rod 74 is slidably connected to a block 76 via a groove 75, and a second spring 77 is fixedly connected between the groove 75 and the side of the block 76. The block 76 can contact the periphery of the winding roller 4 and the guide roller 5. The protrusion 71 and the safety net 8 can be removed by pressing the block 76 inward and pulling out the limiting rod 74.

[0032] Working mode: When working, the motor 61 drives the winding roller 4 to rotate, and at the same time uses the active bevel gear 64 to drive the driven bevel gear 65 to drive the screw 62 to rotate, thereby driving the guide roller 5 to move. At this time, the winding roller 4 rotates and the guide roller 5 drives the safety net 8 to move toward the other side, so as to achieve the effect of spreading the safety net 8. Then, the cover plate is opened to allow the winding roller 4 and the guide roller 5 to expose one end with the clamping part 7, and the clamping block 76 is pressed to make it retract inward, and then the limiting rod 74 is pulled out to make the protrusion 71 lose its fixation so that the safety net 8 can be taken out.
