Description

Technical Field

[0001] The utility model relates to the field of slope protection nets, in particular to a safe and stable slope protection net. Background Art

[0002] Slope protection net is an engineering structure used to protect slopes from natural disasters such as weathering, erosion, and rockfall. It is widely used in civil engineering, especially in highways, railways, mines and other large-scale engineering projects to ensure the stability and safety of slopes.

[0003] In the prior art, the laying of the slope protection net is usually carried out by setting rope loops at the four corners of the slope protection net, the rope loops are set on the rivets, and then the protection net is unfolded on the slope and all the rivets are driven into the harder soil and stone in turn to form nail holes on the surface of the soil and stone. The laying of the slope protection net is completed. The protection net covering the slope can support the gravel on the slope and prevent the gravel from sliding down and causing harm to pedestrians and vehicles below the slope.

[0004] However, the laying method of the slope protection net in the prior art simply relies on the friction between the rivets and the inner wall of the nail hole to fix the rivets. During long-term use, wear will inevitably occur between the rivets and the inner wall of the nail hole. The wear will cause the two to no longer be tightly combined, which will lead to a decrease in friction and the rivets will fall out of the nail hole, which makes the safety and stability of the slope protection net poor. Utility Model Content

[0005] The purpose of the utility model is to provide a safe and stable slope protection net to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a safe and stable slope protection net, comprising: a protection net, rope loops are arranged on the four corners of the protection net, rivets are arranged in the rope loops, a cavity is arranged in the rivet, a side hole is opened on the side of the rivet, the side hole is connected with the cavity, a pointed cone is movably inserted in the side hole, a pushing block is fixed on one end of the pointed cone extending into the side hole, the other end of the pushing block is movably inserted in the cavity, an inclined surface is opened on the top of the pushing block, and a push rod is movably inserted in the cavity.

[0007] Preferably, a push rod hole is provided on the rivet cap, and the push rod is movably inserted in the push rod hole. The push rod is in the form of a rectangular rod body, and the side length of the push rod matches the push rod hole.

[0008] Preferably, two groups of side holes are opened on the surface of the rivet, and two groups of pointed cones and push blocks are also provided. The two groups of pointed cones and push blocks are symmetrically distributed about the axis of the rivet, and the same group of rubber pull straps are fixed between the two groups of push blocks.

[0009] Preferably, a screw hole is provided on the inner wall of the bottom end of the cavity, a screw is provided in the screw hole of the cavity, the screw passes through the rubber strap, and the nut of the screw is pressed on the top end of the rubber strap.

[0010] Preferably, the distance between the bottom end of the push rod and the top end of the screw is the same as the distance that the top end of the push rod protrudes from the nail cap of the rivet.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model provides a safe and stable slope protection net. After the protection net is unfolded on the slope, the push rod is firstly pulled out of the cavity, and then the rivets set in the rope loop are driven into the harder soil and stone by the traditional method to form nail holes on the surface of the soil and stone. Then the push rod is inserted back into the cavity, and the top of the push rod is struck with a heavy hammer to make the push rod move downward in the cavity. The movement of the push rod generates a horizontal component force on the push block through the inclined surface of the push block. This horizontal component force makes the two groups of push blocks The rivet and the eye move in a direction away from each other, and the movement of the push block makes the pointed cone extend from the side hole and penetrate into the inner wall of the nail eye, thereby forming a conical groove on the inner wall of the nail eye. In addition to the friction force of the nail eye on the rivet, there is also an extrusion force of the conical groove on the pointed cone, because the extrusion force of the conical groove on the pointed cone is almost parallel to the movement direction of the rivet out of the nail eye, and this extrusion force will disappear only after the pointed cone or the inner wall of the conical groove is crushed, thus greatly enhancing the safety and stability of the slope protection net.

[0017] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Embodiment 1

[0019] See also Figure 1-Figure 3 The utility model provides a technical solution: a safe and stable slope protection net, comprising: a protection net 1, rope loops 2 are arranged on the four corners of the protection net 1, rivets 3 are sleeved in the rope loops 2, a cavity 7 is arranged in the rivet 3, a side hole 4 is opened on the side of the rivet 3, the side hole 4 is connected with the cavity 7, a pointed cone 5 is movably inserted in the side hole 4, a push block 6 is fixed at one end of the pointed cone 5 extending into the side hole 4, the other end of the push block 6 is movably inserted in the cavity 7, an inclined surface is opened on the top of the push block 6, and a push rod 9 is movably inserted in the cavity 7.

[0020] In actual use, after the protective net 1 is unfolded on the slope, the push rod 9 is first pulled out of the cavity 7, and then the rivets 3 set in the rope loop 2 are driven into the harder soil and stone by traditional methods to form nail holes on the surface of the soil and stone, and then the push rod 9 is inserted back into the cavity 7, and the top of the push rod 9 is hit with a heavy hammer to make the push rod 9 move downward in the cavity 7. The movement of the push rod 9 generates a horizontal component force on the push block 6 through the inclined surface of the push block 6, and this horizontal component force causes the two groups of push blocks 6 to move away from each other. The movement of the pushing block 6 makes the pointed cone 5 extend from the side hole 4 and penetrate into the inner wall of the nail eye, thereby forming a conical groove on the inner wall of the nail eye. In addition to the friction force of the nail eye on the rivet 3, the fixation between the rivet 3 and the nail eye is also due to the squeezing force of the conical groove on the pointed cone 5, because the squeezing force of the conical groove on the pointed cone 5 is almost parallel to the movement direction of the rivet 3 out of the nail eye, and this squeezing force will disappear only after the pointed cone 5 or the inner wall of the conical groove is crushed, thereby greatly enhancing the safety and stability of the slope protection net.

[0021] Embodiment 2

[0022] On the basis of embodiment 1, in order to achieve the goal of not supporting the push rod 9 when striking the push rod 9, a push rod hole 8 is opened on the nail cap of the rivet 3, and the push rod 9 is movably inserted in the push rod hole 8. The push rod 9 is a rectangular rod body, and the side length of the push rod 9 matches the push rod hole 8.

[0023] The push rod hole 8 provided on the nail cap of the rivet 3 cooperates with the push rod 9, so that the push rod 9 can only move in a direction perpendicular to the nail cap of the rivet 3, thereby achieving the purpose of not supporting the push rod 9 when striking the push rod 9.

[0024] Embodiment 3

[0025] On the basis of Example 2, in order to prevent the pointed cone 5 from moving around due to vibration when the rivet 3 is driven into the soil and rock, two groups of side holes 4 are opened on the surface of the rivet 3, and two groups of pointed cones 5 and pushing blocks 6 are also provided. The two groups of pointed cones 5 and pushing blocks 6 are symmetrically distributed about the axis of the rivet 3, and the same group of rubber straps 10 are fixed between the two groups of pushing blocks 6. A screw hole is opened on the inner wall of the bottom end of the cavity 7, and a screw 11 is arranged in the screw hole of the cavity 7. The screw 11 passes through the rubber strap 10, and the nut of the screw 11 is pressed on the top of the rubber strap 10.

[0026] The screw 11 fixes the center of the rubber pull belt 10 on the inner wall of the bottom end of the cavity 7. The rubber pull belt 10 is made of rubber material with moderate elasticity. When the push rod 9 is not inserted into the cavity 7, the rubber pull belt 10 maintains the position of the two groups of push blocks 6 to prevent the push blocks 6 from moving around due to vibration. When the push rod 9 is inserted into the cavity 7 and moves downward to push the two groups of push blocks 6 away from each other, the rubber pull belt 10 will not cause excessive resistance to the movement of the two groups of push blocks 6, thereby achieving the purpose of preventing the pointed cone 5 from moving around due to vibration without affecting the push of the push rod 9 on the push block 6.

[0027] Embodiment 4

[0028] On the basis of the third embodiment, in order to realize the convenience of knowing that the pointed cone 5 has penetrated into the inner wall of the nail hole, the distance between the bottom end of the push rod 9 and the top end of the screw 11 is the same as the distance from the top end of the push rod 9 to the nail cap of the rivet 3.

[0029] After the push rod 9 is inserted into the cavity 7, the bottom end of the push rod 9 is mounted on the top of the inclined surface of the push block 6. At this time, the distance that the push rod 9 extends out of the nail cap of the rivet 3 is equal to the distance between the bottom end of the push rod 9 and the screw 11. When the push rod 9 is struck with a heavy hammer so that the top end of the push rod 9 is flush with the top end of the nail cap of the rivet 3, the push rod 9 must have moved between the two groups of push blocks 6. At this time, the pointed cone 5 must have completely extended out of the side hole 4 and penetrated into the inner wall of the nail eye, thereby realizing the function of conveniently knowing that the pointed cone 5 has penetrated into the inner wall of the nail eye.

[0030] In actual use, after the protective net 1 is unfolded on the slope, the push rod 9 is first pulled out of the cavity 7, and then the rivets 3 set in the rope loop 2 are driven into the harder soil and stone by traditional methods to form nail holes on the surface of the soil and stone, and then the push rod 9 is inserted back into the cavity 7, and the top of the push rod 9 is hit with a heavy hammer to make the push rod 9 move downward in the cavity 7. The movement of the push rod 9 generates a horizontal component force on the push block 6 through the inclined surface of the push block 6. This horizontal component force makes the two groups of push blocks 6 move away from each other, and the movement of the push block 6 makes the pointed cone 5 extend from the side hole 4. The pointed cone 5 is made to penetrate into the inner wall of the nail eye, thereby forming a conical groove on the inner wall of the nail eye. In addition to the friction force of the nail eye on the rivet 3, the fixation between the rivet 3 and the nail eye also includes the squeezing force of the conical groove on the pointed cone 5, because the squeezing force of the conical groove on the pointed cone 5 is almost parallel to the movement direction of the rivet 3 out of the nail eye, and this squeezing force will disappear only after the pointed cone 5 or the inner wall of the conical groove is crushed, thereby greatly enhancing the safety and stability of the slope protection net; the push rod hole 8 opened on the nail cap of the rivet 3 cooperates with the push rod 9, so that the push rod 9 can only move in the direction perpendicular to the nail cap of the rivet 3, thereby achieving The purpose of not supporting the push rod 9 when striking the push rod 9 is achieved; the screw 11 fixes the center of the rubber pull belt 10 on the inner wall of the bottom end of the cavity 7, and the rubber pull belt 10 is made of rubber material with moderate elasticity. When the push rod 9 is not inserted into the cavity 7, the rubber pull belt 10 maintains the position of the two groups of push blocks 6 to prevent the push blocks 6 from moving around due to vibration. When the push rod 9 is inserted into the cavity 7 and moves downward to push the two groups of push blocks 6 away from each other, the rubber pull belt 10 will not cause excessive resistance to the movement of the two groups of push blocks 6, thereby preventing the pointed cone 5 from moving around due to vibration. At the same time, it does not affect the purpose of the push rod 9 to push the push block 6; after the push rod 9 is inserted into the cavity 7, the bottom end of the push rod 9 is mounted on the top of the inclined surface of the push block 6. At this time, the distance that the push rod 9 extends out of the nail cap of the rivet 3 is equal to the distance between the bottom end of the push rod 9 and the screw 11. When the push rod 9 is struck with a heavy hammer and the top end of the push rod 9 is flush with the top end of the nail cap of the rivet 3, the push rod 9 must have moved between the two groups of push blocks 6. At this time, the pointed cone 5 must have completely extended out of the side hole 4 and penetrated into the inner wall of the nail eye, thereby realizing the function of conveniently knowing that the pointed cone 5 has penetrated into the inner wall of the nail eye.
