DETAILED DESCRIPTION

[0028] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The utility model provides an engineering protection net through improvement. The technical solution of the utility model is:

[0030] like Figure 1-Figure 4As shown, an engineering protection net includes multiple columns 1, and a pair of limiting slides 8 are fixedly installed on the side walls of each column 1. An adjustment slot 6 is opened at the end of each column 1, and an adjustment column 2 is slidably installed inside the adjustment slot 6. It also includes an adjustment component and a tensioning component. The height adjustment within a certain range can be achieved through the set adjustment slot 6 and adjustment column 2, thereby improving the practicality of the device.

[0031] Adjustment component, the adjustment component is arranged on the column 1 and the adjustment column 2.

[0032] The adjustment component includes an adjustment cylinder 3 fixedly installed on one side of the column 1, an adjustment screw 4 is rotatably installed inside the adjustment cylinder 3, and a rotating block 5 is fixedly installed at the bottom of the adjustment screw 4. The rotating block 5 is provided to facilitate easy rotation of the adjustment screw 4, thereby achieving the effect of height adjustment.

[0033] The tensioning assembly is arranged on the column 1 and the adjusting column 2.

[0034] The tensioning assembly includes a tensioning rod 9 threadedly connected to the bottom of the column 1 and the end of the adjustment column 2. A threaded groove is provided on the inner and outer sides of each tensioning rod 9. The outer side of each tensioning rod 9 is threadedly connected to a threaded cylinder 10. The threaded cylinder 10 can be moved by the setting of the tensioning rod 9 and the opened internal and external threaded grooves, thereby facilitating the movement of the protective net and thereby increasing the degree of tension.

[0035] Furthermore, a connecting ear plate 7 is fixedly installed on one side of the adjusting cylinder 3 near the adjusting screw 4. The connecting ear plate 7 is threadedly connected to the adjusting screw 4, and the connecting ear plate 7 is slidably fitted with the adjusting slot 6. The connecting ear plate 7 can be used to move the adjusting column 2, thereby facilitating the movement of the tensioning assembly at the end, thereby achieving the height adjustment effect while the tensioning assembly can still work normally.

[0036] Furthermore, a bearing 11 is fixedly installed on one side of each threaded cylinder 10, and a tensioning plate 12 is fixedly installed on the outer ring of each bearing 11. A plurality of protrusions 13 are fixedly installed on the tensioning plate 12 at equal intervals. A cover plate 14 is fixedly installed on one side of each tensioning plate 12 by bolts. The tensioning plate 12 located at the upper part slides with the limiting slide 8. The provided bearing 11 can ensure that the rotation of the threaded cylinder 10 will not affect the tensioning and fixing effect of the tensioning plate 12 and the cover plate 14 on the protective net. The provided plurality of protrusions 13 can be clamped and fixed with the mesh on the protective net, thereby achieving the fixing effect of the protective net.

[0037] Furthermore, a slide groove 15 is provided on the tensioning plate 12 at the upper portion, and a slide plate 16 is fixedly installed on the end portion of the tensioning plate 12 at the bottom portion. The slide plate 16 slides in cooperation with the slide groove 15. The provided slide groove 15 and slide plate 16 can ensure that the tensioning assembly can still achieve a tensioning effect during the height adjustment process.

[0038] Furthermore, a support rod 18 is provided between a pair of adjacent tensioning rods 9, and threaded rods 20 are rotatably installed at both ends of the support rod 18. The threaded rods 20 are threadedly connected to the inside of the adjacent tensioning rods 9. By providing the support rod 18, the protective net in the middle can be tied and fixed, thereby increasing the overall tension of the protective net and thus improving the protective effect.

[0039] Furthermore, a wire mesh 17 is fixedly installed between two pairs of adjacent tensioning plates 12 through a protrusion 13, and a plurality of annular lock buckles 19 are installed on the support rod 18. The support rod 18 and the wire mesh 17 are fixedly connected by the annular lock buckles 19. The plurality of annular lock buckles 19 can easily achieve a pulling effect on the wire mesh 17, and cooperate with the support rod 18 to improve the pulling and fixing effect.

[0040] The specific working method is: after fixing the column 1, fix the tensioning rod 9 on the column 1 and the adjusting column 2 through a threaded connection, and fix the tensioning assembly between a pair of tensioning rods 9. According to the required protection height, the adjusting column 2 is moved by adjusting the screw 4 to achieve the effect of adjusting the protection height. After the height is adjusted, the wire mesh 17 is fixed on the tensioning plate 12 and fixed by the cover plate 14, and the annular lock buckle 19 on the support rod 18 is fixedly connected to the wire mesh 17. At this time, the threaded cylinder 10 is controlled to move the tensioning plate 12 to both sides, thereby achieving the tensioning and fixing effect of the wire mesh 17. The tensioning effect can be improved from another direction through height adjustment, thereby greatly improving the protection effect.
