Description

Technical Field

[0001] The utility model relates to the technical field of slope protection, in particular to a passive protection net transfer column. Background Art

[0002] In order to prevent the falling of dangerous rocks on the slope from affecting the projects below, it is necessary to set up passive protection nets to block the falling rocks. The terrain conditions and the locations of falling dangerous rocks in different areas of the slope are different, so passive protection nets of different heights need to be set up.

[0003] In the prior art, steel columns are usually used for connection of passive protection nets of different heights. However, the connecting cables of the protection nets will produce asymmetric tension on the columns, which will cause the columns to bend and deform. The bending and deformation of the columns will reduce their stability when subjected to external loads, thereby increasing the risk of the entire passive protection system being affected by external forces, which may easily lead to tilting or collapse. The connecting lock of the protection net is connected to the column through a connecting plate, but the connecting plate is usually connected to the column by welding, and the height of the connecting lock of the protection net cannot be subsequently adjusted, affecting the adjustability of the protection net.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The passive protection net transfer column is provided with an adjustment clamping component group and an anti-deformation component group. In the prior art, passive protection nets of different heights usually use steel columns when transferring. However, since the protection net connecting rope will produce asymmetric tension on the column, the column will bend and deform. The bending deformation of the column will reduce its stability when it is subjected to external loads, thereby increasing the risk of the entire passive protection system being affected by external forces, which is easy to cause tilting or collapse. In the corresponding designed anti-deformation component group, the convex frame 1 is connected to the sleeve frame 2 by bolts, the horizontal axis 1 is connected to one end of the threaded rod by a rotating shaft, the threaded rod is connected to the sleeve rod by threads, and one end of the sleeve rod is connected The first and second ends of the cross shaft are connected, the structures of the first and second cross shafts are the same, the second cross shaft is connected to the second protrusion through the rotating shaft, the threaded rod can be moved in the sleeve rod by rotating the threaded rod, and the length of the threaded rod extending in the sleeve rod can be controlled, so that the positions of the adjustment clamping component groups and the connecting cable members of different heights can be adjusted and adapted, and the anti-deformation component group is designed to be connected in the opposite direction of the connecting cable member pulling the supporting column, so as to resist the tension generated by the connecting cable member, thereby avoiding the bending deformation of the supporting column when it is pulled by the connecting cables of different heights, thereby increasing the stability of the supporting column and the overall protection system;

[0016] 2. The passive protective net transfer column is provided with an adjustment clamping component group and an anti-deformation component group, and the protective net connection lock is connected to the column through a connecting plate, but the connecting plate is usually connected to the column by welding, and the protective net connection lock cannot be subsequently adjusted in height, which affects the adjustability of the protective net. In the corresponding designed adjustment clamping component group, by unscrewing the second horizontal axis, the adjustment clamping component group can drive the connecting cable to adjust the upper and lower positions on the supporting column. After adjusting to the appropriate height position, the screw is screwed into the inside of the first sleeve through the second sleeve and the felt gasket to complete the connection between the adjustment clamping component group and the main component group, and the side panel member , frame one and frame two will be clamped on the supporting column, and the felt gasket is placed between frame one and frame two to reduce the friction loss at the connection. In actual use, the protective net will be blown by the wind and will drive the side panels and frame one, which will cause deformation friction at the connection position between frame one and frame two, and the felt gasket is used to pad it for shock absorption, which can improve the practicality and service life of the overall structure. At the same time, compared with the existing technology, this structure can make the connection position between the connecting cable and the supporting column self-adjustable, and the anti-deformation component group can adjust and adapt to the height of different adjustment clamping component groups, thereby enhancing the flexibility and applicability of the overall column use.

[0031] Working principle: In the prior art, passive protection nets of different heights are usually connected with steel columns. However, since the connecting cables of the protection nets will generate asymmetric tension on the columns, the columns will bend and deform. The bending and deformation of the columns will reduce their stability when subjected to external loads, thereby increasing the risk of the entire passive protection system being affected by external forces, which may easily lead to tilting or collapse. In the corresponding designed anti-deformation component group 03, the boss 1 31 is connected to the sleeve frame 23 through bolts, the horizontal axis 1 32 is connected to one end of the threaded rod 33 through a rotating shaft, the threaded rod 33 is connected to the sleeve rod 34 through threads, one end of the sleeve rod 34 is connected to the horizontal axis 2 35, and the structure of the horizontal axis 1 32 and the horizontal axis 2 35 Similarly, the second horizontal axis 35 is connected by a rotating shaft and a second protrusion 36.

The design of the anti-deformation component group 03 is connected in the opposite direction of the connecting cable 12 pulling the supporting column 11, so as to resist the tension generated by the connecting cable 12, thereby avoiding the bending deformation of the supporting column 11 when it is pulled by the connecting cables 12 of different heights, thereby increasing the stability of the supporting column 11 and the overall protection system. The protective net connection lock is connected to the column through a connection plate, but the connection plate is usually connected to the column by welding, and the protective net connection lock cannot be subsequently adjusted in height, which affects the adjustability of the protective net. In the corresponding designed adjustment clamping component group 02, by unscrewing the horizontal axis 2 35, the adjustment clamping component group 02 can drive the connecting cable 12 to adjust the upper and lower positions on the supporting column 11. After adjusting to the appropriate height position, the screw 25 is passed through the sleeve frame 2 23 and the felt gasket 24 and screwed into the sleeve frame 1 22 to complete the connection between the adjustment clamping component group 02 and the main component group 01.

In actual use, the protective net will be blown by the wind and will drive the side panel 21 and the sleeve frame 1 22, which will cause deformation friction at the connection position between the sleeve frame 1 22 and the sleeve frame 23, and the felt gasket 24 is used to pad it for shock absorption, which can improve the practicality and service life of the overall structure.
