Obviously, the described embodiments are only a part of the embodiments of the present application, not all.

[0026] Embodiments

[0027] As shown in Figure 1 , 2 , the present embodiment discloses a hook type metal rod buffering mechanism, which comprises a box body 1 and two buffering assemblies. Among them, the box body 1 is provided with a cover plate 11, and the cover plate 11 and the box body 1 can be connected by bolts. The two ends of the box body 1 are open, and the two buffering assemblies are respectively connected with the box body 1 and are symmetrically distributed left and right, and the two buffering assemblies respectively extend out from the two end openings of the box body 1.

[0028] Specifically, the buffering assembly comprises a pin shaft 2, a steel bar 4 and a steel wire rope assembly. Among them, the pin shaft 2 is fixed with the box body 1, and the pin shaft 2 can be fixed with the box body 1 by welding. The steel bar 4 is folded after passing around the pin shaft 2, so that the steel bar 4 forms a first steel bar segment 41 and a second steel bar segment 42, and the length of the first steel bar segment 41 is shorter than that of the second steel bar segment 42; that is, the steel bar 4 is not folded with the center of the steel bar 4 after passing around the pin shaft 2, so that the lengths of the first steel bar segment 41 and the second steel bar segment 42 formed after folding are different, as shown in Figure 2 .

[0029] The cover plate 11 is provided with a sleeve, and after the steel bar 4 is installed on the pin shaft 2, the end of the pin shaft 2 away from the box body 1 is inserted into the sleeve, and finally the cover plate 11 is fixed and installed on the box body 1 by bolts. The steel wire rope assembly is connected with the first steel bar segment 41 and the second steel bar segment 42.

[0030] Specifically, the steel wire rope assembly comprises a first connecting steel wire rope 7, a second connecting steel wire rope 8, a disc buckle 9 and a traction steel wire rope 10. Among them, one end of the first connecting steel wire rope 7 is connected with the first steel bar segment 41, and the other end is connected with the disc buckle 9; that is, the end of the first steel bar segment 41 is provided with a first connecting ear plate 6, and the first connecting steel wire rope 7 is connected with the first connecting ear plate 6, so that the first connecting steel wire rope 7 and the first steel bar segment 41 are connected together. Correspondingly, one end of the second connecting steel wire rope 8 is connected with the second steel bar segment 42, and the other end is connected with the disc buckle 9; that is, the end of the second steel bar segment 42 is provided with a second connecting ear plate 12, and the second connecting steel wire rope 8 is connected with the second connecting ear plate 12, so that the second connecting steel wire rope 8 and the second steel bar segment 42 are connected together. The traction steel wire rope 10 is connected with the disc buckle 9.

[0031] The first connecting steel wire rope 7 and the second connecting steel wire rope 8 have the same length, and when the traction steel wire ropes 10 of the two buffer assemblies are connected with external components, for example, as shown in Figure 4 When the hook-tooth type metal bar buffer mechanism is used for traction of the protective net steel column, the traction steel wire rope 10 of one buffer assembly of the hook-tooth type metal bar buffer mechanism is connected with the protective net steel column 13, and the traction steel wire rope 10 of the other buffer assembly is connected with the anchor rod 14 anchored on the slope. At this time, the two buffer assemblies on the hook-tooth type metal bar buffer mechanism are in the same straight line. Since the length of the first steel bar segment 41 is longer than that of the second steel bar segment 42, and the first connecting steel wire rope 7 and the second connecting steel wire rope 8 have the same length, the first connecting steel wire rope 7 of the two buffer assemblies is in a taut state, and it, together with the traction steel wire rope 10 and the steel bar 4, jointly tractions the protective net steel column. At this time, the traction force is smaller than the force resisting deformation of the steel bar 4, and the steel bar 4 does not deform. The second connecting steel wire rope 8 is in a slack state, as shown in Figure 1 When the stones on the slope fall onto the protective net, since the protective net is installed on the top of the steel column, the impact force of the falling stones is applied to the protective net steel column, and the steel column swings downward. At this time, the tension on the steel bar of the two buffer assemblies increases, and under the action of the tension, the steel bar 4 deforms about the pin shaft. The lengths of the first steel bar segment 41 and the second steel bar segment 42 become the same, and the first connecting steel wire rope 7 and the second connecting steel wire rope 8 are both in a taut state, as shown in Figure 3 The impact force of the falling stones is buffered by the deformation of the steel bar 4.

[0032] As another embodiment, the pin shaft 2 is provided with a gear 3, and the gear 3 can rotate on the pin shaft 2. Correspondingly, the steel bar 4 is provided with a tooth hole 5 matched with the gear 3. The gear 3 and the tooth hole 5 are matched to prevent the steel bar 4 from moving on the pin shaft.

[0033] The two symmetrically distributed buffer assemblies buffer the impact force, and the buffering effect is improved.

[0034] It should be noted that all the features disclosed in the specification, or the steps of all the methods or processes disclosed, can be combined in any manner, except for the mutually exclusive features and / or steps.

[0035] In addition, the above specific embodiments are exemplary, and those skilled in the art can think of various solutions under the inspiration of the disclosure of the present application, and these solutions also belong to the disclosed scope of the present application and fall within the protection scope of the present application. Those skilled in the art should understand that the specification and drawings of the present application are illustrative and do not constitute a limitation on the claims.
