The protective net used in mines is widely used in various types of mines such as coal mines, gold mines, copper mines, iron mines, as well as underground engineering, tunnels and other fields. In coal mines, protective nets are usually used for support in tunnels, ramps, working faces and other locations; in large-scale mining such as gold and copper mines, protective nets are often used to prevent rock collapse and limit the scope of the crushing area; in underground engineering and tunnel construction, protective nets can be used as an important supplement to slopes and reinforced concrete structures to increase the stability of geological bodies.

[0041] like Figure 4 , Figure 5 , Figure 7 , Figure 8 As shown, the transmission assembly 15 includes a driving wheel 1501, the outside of the driving wheel 1501 is meshed with a first driven wheel 1502, the outer edge of the first driven wheel 1502 is meshed with a second driven wheel 1503, the inside of the second driven wheel 1503 is fixedly connected with a screw rod 1504, the inside of the driving wheel 1501 is fixedly connected to the transmission shaft 14, the middle part of the first driven wheel 1502 is rotatably connected to the mounting frame 7, the outside of the second driven wheel 1503 is not in contact with the second fixed frame 16, the outside of the screw rod 1504 is rotatably connected to the second fixed frame 16, and the two ends of the screw rod 1504 are respectively threadedly connected to the first movable plate 1201 and the second movable plate 1204;

[0043] The working principle and use process of the present invention:

[0044] First, the driving motor 301 drives the driving shaft 302 to rotate, and the driving shaft 302 drives the driving rings 303 at both ends to rotate. At this time, the driving shaft 302 unwinds the protection net 4, and the spring sheet 5 extends outward as the protection net 4 is unwound. The connecting plate 601 drives the connecting column 602 to move through the extension of the spring sheet 5 and the protection net 4, and the connecting column 602 is inserted into the connecting piece 803.

The first bevel gear 9 and the threaded barrel 10 are threadedly rotated so that the first bevel gear 9 drives the threaded barrel 10 to rotate. At this time, the threaded barrel 10 gradually moves toward the inside of the fixing member 801, and one side of the threaded barrel 10 gathers each clamping member 804 so that the clamping member 804 forms a complete circle. The clamping member 804 turns over with the hinged part with the connecting member 803 as the center of the circle. The fixing spring 805 is stretched and deformed as the clamping member 804 turns over. At this time, the clamping member 804 clamps and fixes the connecting column 602;

[0046] During the rotation of the transmission shaft 14, the transmission shaft 14 drives the driving wheel 1501 to rotate, and the driving wheel 1501 engages with the first driven wheel 1502 to make the first driven wheel 1502 rotate, and the first driven wheel 1502 engages with the second driven wheel 1503 to drive the second driven wheel 1503 to rotate. At this time, the second driven wheel 1503 drives the screw rod 1504 to rotate, and the screw rod 1504 and the first movable plate 1201 and the second movable plate 1204 are threadedly rotated respectively, so that the screw rod 1504 drives the first movable plate 1201 and the second movable plate 1204 to move along the inside of the mounting frame 7. At this time, the first movable plate 1201 and the second movable plate 1204 approach each other until the two clamp and fix the connecting column 602 and the connecting plate 601, so that the connecting module 6 fixes the protective net 4 to complete the operation.
