Technical Field

[0001] The utility model relates to an anti-falling net, in particular to an anti-falling net for an inspection well which can be quickly disassembled. Background Art

[0002] Inspection wells are designed for easy maintenance of urban underground infrastructure, including power supply, water supply, drainage, sewage, communications, cable TV, gas pipes, and streetlight lines. They are typically located at pipeline intersections, bends, changes in pipe diameter or slope, and at regular intervals along straight pipe sections to facilitate regular inspection of ancillary structures.

[0003] In the prior art, an anti-fall net is required inside the inspection well to prevent accidents. However, the anti-fall net currently used in the inspection well is hung on the wall of the inspection well by a hook during installation. Therefore, when disassembling, it is necessary to lean over the edge of the inspection well and stick out half of the body to disassemble. This disassembly method is inconvenient and dangerous. At the same time, when bending over to disassemble, some gases inside the inspection well are pungent and can easily cause damage to the worker's body. Utility Model Content

[0006] As a preferred technical solution of the present invention, a fixed ring is provided in the middle of the anti-fall net.

[0007] As a preferred technical solution of the present invention, the sides of the plurality of inserts are fixedly connected to corresponding mounting plates via connecting rods, and the plurality of mounting plates are fixedly mounted on the inner wall of the inspection well.

[0008] As a preferred technical solution of the present invention, expansion strips are fixedly provided at equal intervals on the inner walls of the plurality of insert tubes.

[0009] As a preferred technical solution of the present invention, magnets are fixedly installed in the middle of the plurality of pulling ropes.

[0010] As a preferred technical solution of the present invention, a detection rope is inserted into the interior of the fixed column, the diameter of the detection rope is the same as the diameter of the fixed ring, and the material of the detection rope is the same as that of the anti-fall net and the braided thick rope.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model provides an insertion tube and an insertion rod. The insertion tube is fixed to the inner wall of the inspection well through a mounting plate. The insertion tube and the insertion rod are engaged and connected, which replaces the original connection method between the anti-fall net and the inspection well through hanging by a hook. At the same time, when disassembling, it is only necessary to pull the pulling rope to disengage the insertion rod and the insertion tube to disengage the anti-fall net. This installation and disassembly method does not require the staff to lean over to disassemble, and has a higher safety factor and is more convenient.

[0013] 2. The utility model is provided with a detection rope. When in use, the detection rope passes through a fixed ring and is located below the anti-fall net, making contact with a deeper part of the inspection well.

[0020] See also Figure 1-4 The utility model provides a technical solution for a quickly detachable anti-fall net for an inspection well:

[0021] Example 1:

[0022] according to Figure 1 、 Figure 2 and Figure 4 As shown, a quickly detachable anti-fall net for an inspection well comprises:

[0023] The anti-fall net 2, the side of the anti-fall net 2 is fixedly connected with a braided thick rope 1, which is convenient for tightening the side of the anti-fall net 2 and improving the strength of the anti-fall net 2. A fixed ring 3 is provided in the middle of the anti-fall net 2;

[0024] The insertion rods 5 are fixedly set at multiple corners of the anti-fall net 2, and the tops of the multiple insertion rods 5 are fixedly installed with fixing plates 4. The outer sides of the multiple insertion rods 5 are snap-connected with insertion tubes 6, and the sides of the multiple insertion tubes 6 are fixedly connected with mounting plates 7 through connecting rods 8. The multiple mounting plates 7 are fixedly installed on the inner wall of the inspection well. The snap-fit ​​connection between the multiple insertion rods 5 and the corresponding insertion tubes 6 facilitates the disassembly and installation of the anti-fall net 2. The mounting plate 7 arranged on the inner wall of the inspection well replaces the original hook structure on the inner wall of the inspection well, which facilitates the rapid installation and disassembly of the overall anti-fall net 2 and improves the installation strength of the anti-fall net 2.

[0025] Expansion strips 14 are fixedly provided at equal intervals on the inner walls of the plurality of insert tubes 6 . The expansion strips 14 enable the insertion rods 5 and the insert tubes 6 to be more tightly engaged, and will not become loose during the engagement process.

[0026] In specific use, the utility model is a quickly detachable anti-fall net for inspection wells. When installing the anti-fall net 2, first, multiple mounting plates 7 are installed on the inner wall of the inspection well, so that the corresponding insertion tubes 6 are fixed on the inner wall of the inspection well. Then, during installation, the corresponding insertion rods 5 are inserted into the interior of the corresponding insertion tubes 6. The expansion strips 14 provided make the insertion rods 5 and the insertion tubes 6 fit more tightly, so that the entire anti-fall net 2 is installed inside the inspection well. When disassembling the anti-fall net 2, the pulling ring 13 is also pulled to pull up the pulling rope 9, and a separate pulling rope 9 is pulled to drive the insertion rod 5 to disengage from the corresponding insertion tube 6. The anti-fall net 2 can be disassembled by performing the operations in sequence.

[0027] Example 2:

[0028] Based on the first embodiment, Figure 1 and Figure 3As shown, the pulling ropes 9 are fixedly arranged on the top of the multiple fixing plates 4, and the tops of the multiple pulling ropes 9 are fixedly connected to the fixing columns 11. The fixing columns 11 fix the tops of the multiple pulling ropes 9 together. The tops of the fixing columns 11 are provided with pulling rings 13. The provided pulling rings 13 facilitate lifting the pulling ropes 9 gathered on the anti-fall net 2;

[0029] A magnet 10 is fixedly installed in the middle of the multiple pulling ropes 9. The magnets 10 are arranged to attract each other, thereby preventing the multiple pulling ropes 9 from being entangled together and facilitating the pulling together through the pulling ring 13;

[0030] A detection rope 12 is inserted into the interior of the fixed column 11. The diameter of the detection rope 12 is the same as the diameter of the fixed ring 3, and the material of the detection rope 12 is the same as the material of the anti-fall net 2 and the braided thick rope 1. When the anti-fall net 2 is placed inside the inspection well, the inspection rope 12 passes through the fixed ring 3 and contacts deeper into the inspection well. Since it is made of the same material as the anti-fall net 2 and the braided thick rope 1, the status of the anti-fall net 2 and the braided thick rope 1 can be judged by the status of the detection rope 12 to determine whether they are rotten and need to be replaced.

[0031] During specific use, the utility model is a quickly detachable anti-fall net for inspection wells. After the anti-fall net 2 is fixed inside the inspection well, the detection rope 12 is inserted into the inside of the fixed ring 3 so that it penetrates into the inside of the inspection well. Since the detection rope 12 is made of the same material as the anti-fall net 2 and the braided thick rope 1, the state of the anti-fall net 2 and the braided thick rope 1 can be judged by the state of the detection rope 12 to determine whether they are rotten and need to be replaced. Afterwards, multiple pulling ropes 9 are gathered together by the magnet 10 and placed on top of the anti-fall net 2. When the anti-fall net 2 is disassembled, the entire pulling rope 9 is driven upward as a whole by pulling the pulling ring 13, thereby disassembling the anti-fall net 2.
