Description

Technical Field

[0001] The invention relates to the technical field of safety protection, and in particular to a damper of a slope anti-rockfall impact protection net. Background Art

[0002] In order to prevent unstable mountain rocks from falling and causing serious harm to people, vehicles, buildings, etc., various types of protective nets serve as "safety guards" for the safety of life and property in modern society.

[0003] Protective nets are divided into active protective nets and passive protective nets. Active protective nets are covered and wrapped with structures such as wire (rope) nets, grille nets (twisted double nets), support ropes, anchor rods, etc. on the rocks of the slope to be protected to limit weathering and peeling of slope rocks or collapse of dangerous rocks (covering and fixing function); passive protective nets are composed of and supported structures such as steel columns, support ropes, pull ropes, anchor rods, decompression rings, wire (rope) nets, grille nets (twisted double nets) in the area where dangerous rocks fall to intercept falling objects (interception and guidance function).

[0004] During the construction of passive protective nets, dampers will be installed. The dampers will consume the energy of falling rocks while the protective net is being impacted by them, thereby preventing the falling rocks from passing through the protective net and causing harm to people, vehicles, buildings, etc.

[0005] The existing damper is mainly composed of a sealing tube, a shock-absorbing spring and a pull rod. The pull rod is connected to the column on which the wire mesh is installed through a steel cable. The shock-absorbing spring is installed in a steel pipe, and the steel pipe is installed underground through an anchor rod or a fixing device. When falling rocks hit the protective net, the pressure rod will be pulled by the steel cable, and the pressure rod will pull the shock-absorbing spring. The energy of the falling rocks is consumed by the pulling of the shock-absorbing spring. However, when the above-mentioned damper is in use, the shock-absorbing spring inside the steel pipe will undergo irreversible deformation. When the deformation inside the damper is too large, it will affect the performance of the damper, resulting in a reduction in the protective effect of the protective net. At this time, the staff needs to replace the damper with a new one, which is costly. Summary of the invention

The drawings described in the present invention are only schematic diagrams of the structure.

[0025] The present invention provides a damper for a slope anti-rockfall impact protection net, comprising a sealed tube 1 and a pull rod 2 horizontally inserted in the sealed tube 1, and also comprising a first damping assembly 3 arranged in the sealed tube 1, wherein the first damping assembly 3 comprises a horizontally arranged moving block 31, one end of the moving block 31 is fixedly connected to the pull rod 2, one side of the moving block 31 is fixedly connected to a horizontally arranged first telescopic rod 32, one end of the first telescopic rod 32 is fixedly connected to the inner bottom of the sealed tube 1, a first reset spring 33 is sleeved on the first telescopic rod 32, one end of the first telescopic rod 32 is fixedly connected to the inner bottom of the sealed tube 1, and the other end is fixedly connected to the moving block 31. The moving block 31 is fixedly connected, and a second damping assembly 4 is provided in the sealing tube 1. The second damping assembly 4 includes a pair of hinged rods 41. The pair of hinged rods 41 are horizontally hinged on an opposite side of the moving block 31, and the other ends are hinged with a slider 43. A pair of first limiting slide grooves 42 are opened at the bottom of the sealing tube 1, and a pair of sliders 43 are respectively slidably embedded in the first limiting slide grooves 42. One side of the pair of sliders 43 is fixedly connected with a second telescopic rod 44, and a second return spring 45 is sleeved on the second telescopic rod 44. The second telescopic rod 44 and the second return spring 45 are both arranged in the slider 43 and fixedly connected to the sealing tube 1.

[0026] When rocks fall on the protective net, the protective net is pressed, and the protective net pulls the set pull rod 2 through the steel cable. At this time, the pull rod 2 moves and pulls the set first telescopic rod 32 and the first return spring 33, and the first return spring 33 is used to initially consume the energy generated by the falling rocks. When the pull rod 2 moves, the hinged hinge rod 41 causes the slider 43 to slide in the first limiting slide groove 42, and the sliding slider 43 presses the set second telescopic rod 44 and the second return spring 45, so as to further reduce the energy generated by the falling rocks. The present invention not only improves the buffering effect through the joint action of the first damping component 3 and the second damping component 4, but also effectively prevents the return spring in the damper from being irreversibly deformed due to the excessive energy of the falling rocks through the joint action of the first return spring 33 and the second return spring 45 from the vertical and horizontal directions.

[0027] Preferably, a third damping assembly 5 is provided in the sealing tube 1, and the third damping assembly 5 includes a first damping block 51 and a second damping block 52. A plurality of third return springs 53 are fixedly connected to the side of the first damping block 51 and the second damping block 52 away from each other, and a second limiting groove 54 is provided on the side of the first damping block 51 and the second damping block 52 close to each other, so that the first damping block 51 and the second damping block 52 are squeezed when the pull rod 2 moves.

[0028] The present invention also provides a third damping assembly 5. When the pull rod 2 is moved by the tension of the steel cable, the first damping block 51 and the second damping block 52 will be squeezed to both sides. The moving first damping block 51 and the second damping block 52 will squeeze the third return spring 53. When the third return spring 53 needs to be reset, it will generate pressure to clamp the pull rod 2 by pressing the first damping block 51 and the second damping block 52, thereby further reducing the energy generated by the falling rocks. Through the cooperation of the first damping assembly 3, the second damping assembly 4 and the third damping assembly 5, not only the performance of the damper is enhanced, but also the excessive energy of the falling rocks can be effectively prevented from causing irreversible deformation of the return spring in the damper, thereby affecting the performance of the damper.

[0029] Preferably, the pull rod 2 consists of a connecting tube 21 and an extrusion block 22. The connecting tube 21 is connected to the steel cable through the mounting assembly 9. The connecting tube 21 is arranged to penetrate into a limiting channel formed by the first damping block 51 and the second damping block 52, and the extrusion block 22 is arranged to be truncated cone-shaped, and the radius gradually decreases as it approaches the first damping block 51. The truncated cone part is arranged in the limiting channel formed by the first damping block 51 and the second damping block 52, and the surface of the second limiting groove 54 and the surface of the extrusion block 22 are both arranged to be frosted surfaces.

[0030] In the present invention, the pull rod 2 is composed of a connecting tube 21 and an extrusion block 22. As the extrusion block 22 approaches the first damping block, its radius gradually decreases and it is partially arranged in the limiting channel formed by the first damping block 51 and the second damping block 52. When the pull rod 2 is subjected to the tension of the steel cable, it will pull the extrusion block 22 through the connecting tube 21. As the extrusion block 22 moves, the first damping block 51 and the second damping block 52 will move to opposite sides and squeeze the third return spring 53. The extrusion block 22 is set to a truncated cone shape, which can better cooperate with the first damping block 51 and the second damping block 52 to bear force evenly. The surface of the second limiting slide groove 54 and the surface of the extrusion block 22 are both set to frosted surfaces, which is conducive to the first damping block 51 and the second damping block 52 clamping the extrusion block 22, and the extrusion block 22 rubs against the inner surfaces of the first damping block 51 and the second damping block 52, which can further reduce the energy generated by falling rocks.

[0031] Preferably, the first damping block 51 and the second damping block 52 are fixedly connected to a limiting rod 6 on one side away from each other, one end of the limiting rod 6 slides through the sealing tube 1, the limiting rod 6 is placed on the outer side of the sealing tube 1 and is fixedly connected to a support block 7, the support block 7 is fixedly connected to a fourth return spring 8, and the fourth return spring 8 is sleeved on one end of the limiting rod 6 and fixedly connected to the sealing tube 1.

[0032] When the first damping block 51 and the second damping block 52 move away from each other, they will squeeze the set limit rod 6 at the same time. The set limit rod 6 guides the first damping block 51 and the second damping block 52 on the one hand, so that the first damping block 51 and the second damping block 52 directly press the third return spring 53, which can better clamp the extrusion block 22, and when the limit rod 6 moves, the movement of the limit rod 6 is limited by the set fourth return spring 8, and the moving extrusion block 22 is clamped by the joint action of the third return spring 53 and the fourth return spring 8, thereby enhancing the damping effect of the damper and protecting the third return spring 53 and the fourth return spring 8.

[0033] Preferably, an installation component 9 is provided at the bottom of the sealing tube 1, and the installation component 9 includes a first installation plate 91, the first installation plate 91 is fixedly connected to the bottom of the sealing tube 1, a mounting tube 92 is fixedly connected to the bottom of the first installation plate 91, and a support tube 95 buried in the ground is provided with a second installation plate 93 fixedly sleeved on the support tube 95, the installation tube 92 is threadedly embedded in the support tube 95, and the first installation plate 91 and the second installation plate 93 are connected by mounting bolts 94.

[0034] The present invention connects the sealing tube 1 with the support tube 95 through the installation component 9. The support tube 95 is directly buried underground. After the installation tube 92 is threadedly inserted into the support tube 95, the first installation plate 91 and the second installation plate 93 will be tightly attached at this time. At this time, the first installation plate 91 and the second installation plate 93 are connected together through a plurality of set installation bolts 94 to stably connect the sealing tube 1 with the support tube 95 to prevent the sealing tube 1 from shaking and affecting the coordination between the internal components.

[0035] Preferably, a connecting assembly 10 is provided at one end of the connecting tube 21 away from the extrusion block 22, and the connecting assembly 10 includes a connecting block 101, which is fixedly connected to the end of the connecting tube 21, and an embedding groove 102 is provided on the connecting block 101, a connecting ring 103 is embedded in the embedding groove 102, and the connecting ring 103 is connected to the steel cable, a connecting screw 104 is threadedly embedded on the connecting block 101, and a threaded groove matching the connecting screw 104 is provided in the connecting ring 103.

[0036] The present invention connects the steel cable and the pull rod 2 through a connecting assembly 10, and inserts a connecting ring 103 at the end of the steel cable into an embedding groove 102 provided on a connecting block 101. Then, a connecting screw 104 is threadedly penetrated and installed on the connecting block 101 and the connecting ring 103 in sequence. In this embodiment, a threaded groove matching the connecting screw 104 is provided in the connecting ring 103. When the connecting screw 104 is connected with the connecting ring 103, the steel cable can be stably connected to the pull rod 2 as a whole. This is not only convenient and quick to use, but also firmly connects the steel cable and the pull rod 2, effectively preventing shaking at the connection between the steel cable and the pull rod 2, resulting in uneven force on the pull rod 2, and causing the force generated by falling rocks to be unable to be quickly transmitted to the pull rod 2, affecting the rapid use of the damper.

[0037] The method of using the damper of the slope anti-rockfall impact protection net of the present invention is as follows:

[0038] After the support tube 95 is buried underground and the mounting tube 92 is threadedly inserted into the support tube 95, the first mounting plate 91 and the second mounting plate 93 will be tightly attached to each other. At this time, the first mounting plate 91 and the second mounting plate 93 are connected together by a plurality of mounting bolts 94 to stably connect the sealing tube 1 to the support tube 95.

[0039] The connecting ring 103 at the end of the steel cable is inserted into the embedding groove 102 provided on the connecting block 101, and then the connecting screw 104 is threadedly penetrated and installed on the connecting block 101 and the connecting ring 103 in sequence. In this embodiment, a threaded groove matching the connecting screw 104 is provided in the connecting ring 103. When the connecting screw 104 is connected with the connecting ring 103, the steel cable can be stably connected to the pull rod 2 as a whole.

[0040] When the falling rocks fall on the protective net, the steel cable will pull the pull rod 2. At this time, the pull rod 2 will move and pull the first telescopic rod 32 and the first return spring 33. The energy generated by the falling rocks will be initially consumed by the first return spring 33. When the pull rod 2 moves, the slider 43 will slide in the first limiting slide groove 42 through the hinged hinge rod 41. The sliding slider 43 will press the second telescopic rod 44 and the second return spring 45 to further reduce the energy generated by the falling rocks.

[0041] As the radius of the extrusion block 22 gradually decreases as it approaches the first damping block and a part of it is arranged in the limiting channel formed by the first damping block and the second damping block, when the pull rod 2 is subjected to the tension of the steel cable and pulls the extrusion block 22 through the connecting tube 21, as the extrusion block 22 moves, the first damping block 51 and the second damping block 52 will move to opposite sides and squeeze the third return spring 53. The extrusion block 22 is arranged in a truncated cone shape, which can better cooperate with the first damping block 51 and the second damping block 52 to bear the force evenly. The surface of the second limiting groove 54 and the surface of the extrusion block 22 are both arranged as frosted surfaces, which is conducive to the first damping block 51 and the second damping block 52 clamping the extrusion block 22, and the extrusion block 22 rubs against the inner surfaces of the first damping block 51 and the second damping block 52, which can further reduce the energy generated by the falling rocks.

[0042] When the first damping block 51 and the second damping block 52 move away from each other, they will squeeze the set limit rod 6 at the same time. The set limit rod 6 guides the first damping block 51 and the second damping block 52 on the one hand, so that the first damping block 51 and the second damping block 52 directly press the third return spring 53, which can better clamp the extrusion block 22, and when the limit rod 6 moves, the movement of the limit rod 6 is limited by the set fourth return spring 8, and the moving extrusion block 22 is clamped by the joint action of the third return spring 53 and the fourth return spring 8, thereby enhancing the damping effect of the damper and protecting the third return spring 53 and the fourth return spring 8.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
