Description

Technical Field

[0001] The utility model relates to the field of building construction protection, in particular to a protection net used for building construction. Background Art

[0002] Protective nets can be used in various industrial fields that require safety and protection, mainly as building protection nets, sports safety nets, transportation safety nets, snow nets, agricultural nets, shade nets, etc. In order to prevent unstable falling rocks from causing serious harm to people and vehicles during the construction process, various types of protective nets serve as "safety guards" for personal and property safety in modern society. In the construction field, especially in places with dense pedestrian traffic in cities, when construction is carried out on the ground, the outer layer is usually surrounded by protective nets to isolate the construction site and block the garbage, gravel and other debris generated during the construction process to prevent harm to pedestrians.

[0003] Since the existing protective net is spliced ​​by multiple protective nets, and the protective height of a single existing protective net is limited, and when the protective height needs to be increased, another group is manually installed on the basis of a protective net to increase the protection range, which is not only time-consuming and laborious during installation, but also not very stable. Therefore, a protective net for construction is proposed to address the above problems. Utility Model Content

All four groups of first connecting rods are L-shaped.

[0007] Preferably, mounting rods are fixedly installed on the upper parts of the one-side surfaces of the two circular racks outside the telescopic holes on the upper side surface of the second protective net. Second connecting rods are fixedly installed on the upper surfaces of the two ends of the two mounting rods away from the circular racks.

[0008] Preferably, second fixing rings corresponding to the second connecting rods are fixedly installed on the upper surfaces of the two ends above the second protective net.

[0009] Preferably, the lifting mechanism includes two connecting ports, which are respectively opened on the upper side surfaces of one sides of the two groups of mounting columns and penetrate into the telescopic holes. The tooth sections of the two circular racks are respectively located at the two connecting ports.

[0010] Preferably, side plates are fixedly installed on both sides of the connecting ports on the mounting columns.

[0023] When working, by first fixing the two groups of mounting columns 1 on the construction ground during protection, the No. 1 protection net 2 and the No. 2 protection net 3 are then installed between the two groups of mounting columns 1, thereby forming a group of protection nets, which can be arranged and distributed in sequence according to the construction area. At the same time, under the action of the lifting mechanism 9, the circular rack 12 can be pushed to slide and extend upward, and the circular rack 12 can be connected with the top of the No. 2 protection net 3, so that the No. 2 protection net 3 can be pushed upward to slide and extend on one side of the No. 1 protection net 2 to increase the protection height, and the sliding bar 5 fixedly connected to the No. 2 protection net 3 is slidably connected in the sliding groove 4, so that the No. 2 protection net 3 is slidably installed on one side of the No. 1 protection net 2, thereby solving the problem that the existing protection net is spliced ​​by multiple protection nets, and the protection height of a single existing protection net is limited, and when the protection height needs to be increased, another group is manually installed on the basis of one protection net to increase the protection range, which is not only time-consuming and labor-intensive during installation, but also has low stability.

[0024] Furthermore, two groups of No. 1 fixing rings 6 are fixedly distributed on the opposite side surfaces of the two groups of mounting columns 1, two groups of No. 1 connecting rods 10 are fixedly distributed on the two end surfaces of the No. 1 protective net 2, and the four groups of No. 1 connecting rods 10 are all set to be L-shaped.

[0025] During operation, when installing the No. 1 protection net 2 , the four groups of No. 1 connecting rods 10 are respectively inserted into the four groups of No. 1 fixing rings 6 , so that the No. 1 protection net 2 and the No. 2 protection net 3 can be detachably installed between the two groups of installation columns 1 .

The two groups of mounting brackets 904 are both in the shape of "冂", with the open sides of the two groups of mounting brackets 904 facing upward. Worms 905 are rotatably installed on the inner surfaces of one side of the two groups of mounting brackets 904. The two worms 905 are respectively in meshing engagement with the teeth of the two turbines 903. The other ends of the two worms 905 both rotatably penetrate to the outside of the mounting brackets 904 and are fixedly installed with cranks 906.

[0035] During operation, the crank 906 can be shaken to rotate the worm 905. When the worm 905 rotates, it will drive the turbine 903 to rotate.

The mounting rod 13 is fixedly connected to the upper ends of both sides of the second protective net 3 through the second connecting rod 11. Thus, when the circular rack 12 rises, it will push the second protective net 3 to rise to increase the height of the protection. When installing the first protective net 2, the two second fixing rings 7 are respectively sleeved on the two second connecting rods 11, so that the two circular racks 12 are detachably connected to the upper ends of both sides of the second protective net 3. Through the design of the connection port 901, the circular rack 12 in the telescopic hole 8 can be driven. By driving the gear 907 to rotate, when the gear 907 rotates, it will drive the circular rack 12 to slide upward and extend in the telescopic hole 8, so as to achieve the purpose of extending the second protective net 3. The crank 906 can be shaken to rotate the worm 905. When the worm 905 rotates, it will drive the turbine 903 to rotate. Since the turbine 903 and the gear 907 are on the same rotating shaft, when the turbine 903 rotates, it will drive the gear 907 to rotate together to drive the circular rack 12 to slide and extend. Under the self-locking effect of the turbine 903 and the worm 905, it can be locked after the extension.
