fig. 2 is a schematic structural diagram of the triangular connecting piece of the invention.
The codes in the figure are respectively: 1 is spine portion, 2 is the activity chamber, 3 is first magnet, 4 is the second magnet, 5 is ground inserted bar, 6 is the spring, 7 is the piston rod, 8 is the spacing ring, 11 is the net twine, 12 is the triangle connecting piece, 13 is the wire casing.
Detailed Description
As shown in fig. 1, the suspension type fixing member for a slope protection net for road engineering comprises a slope protection net fixed by more than one fixing member, the fixing member comprises a ground insertion rod 5, the bottom of the ground insertion rod 5 is provided with a spine portion 1, the ground insertion rod 5 is inserted into slope soil through the spine portion 1, the middle of the ground insertion rod 5 is provided with a movable cavity 2, a top through hole of the movable cavity 2 is provided with a piston rod 7 through the through hole, the bottom of the piston rod 7 extends into the movable cavity 2, the extending end of the piston rod is connected with a first magnet 3, the bottom of the movable cavity 2 is provided with more than one second magnet 4 superposed with each other over the first magnet 3, the first magnet 3 and the second magnet 2 are of opposite attraction structure, a buffer zone is formed between the first magnet 3 and the second magnet 2, and the buffer zone must be within the magnetic force range of the two magnets, that is, the second magnet 2 and the first magnet 3 are within the attraction range, but the two magnets do not directly contact and attract each other.
In this embodiment, the extending end of the piston rod 7 is further fixedly provided with a limiting ring 8, the inner wall of the movable cavity 2 is provided with an annular buffer cavity 1, two ends of the limiting ring 8 respectively extend into the annular buffer cavity 1, the bottom surface of the annular buffer cavity 1 is fixedly provided with more than one group of springs 6, and the limiting ring 8 is installed in the annular buffer cavity 1 and contacts with the upper end surfaces of the more than one group of springs 6. Because the limit ring 8 is arranged, the limit ring 8 is contacted with the upper end surface of the spring 6 on the bottom surface of the annular buffer cavity 1, the whole piston rod and the first magnet are supported by more than one group of springs 6, and because the second magnet and the first magnet have an adsorption force, the magnetic force of the second magnet is always used for adsorbing the first magnet to approach the second magnet at the bottom, therefore, even if the piston rod is pulled out towards the outside, the limit ring can also limit the top of the annular buffer cavity, so that the piston rod can not be continuously pulled out, the piston rod automatically returns after losing the tensile force, the magnetic force of the first magnet and the second magnet must be strong enough, so that the piston rod can be adsorbed back no matter how long the piston rod is pulled out, but because of the limitation of the springs, the first magnet and the second magnet can not be contacted all the time, so that the piston rod can be adsorbed towards the inside all the time, thereby tensioning the external slope protection net.
As shown in fig. 2, a triangular connecting member 12 is arranged at the extending end of the top of the piston rod, one of the net wires 11 of the slope protection net is arranged on the triangular connecting member 12, the bottom of the triangular connecting member 12 is welded with the top of the piston rod, a wire groove 13 is arranged in the middle of the top of the triangular connecting member 12 in a penetrating manner, the net wire 11 of the slope protection net is buckled in the wire groove, two ends of the net wire 11 extend out of two sides of the triangular connecting member 12, the fixing member is integrally buried in slope soil, and the outer side end face of the fixing member is exposed out of the slope.
