Description

Technical Field

[0001] This invention relates to the field of slope protection technology, and in particular to a passive protection net for slope rockfall. Background Technology

[0002] Currently, to ensure the safety of fractured rock slopes, passive protective nets are often installed below the slope to protect against rockfalls, boulders, and shallow collapses caused by weathering, rainwater, or vibration. The rock mass at the top of the slope has significant potential energy; once a rock fragment collapses, this potential energy can be converted into kinetic energy, posing a serious geological hazard risk and being one of the most important internal factors affecting the stability of open-pit mining slopes. To ensure the safety of operations on the platform below, passive protective nets are used to intercept sporadic rock fragments falling and rolling down the slope. However, existing protective nets are fixed to posts on both sides, resulting in a lack of sufficient buffering mechanisms to continuously cushion the impact of falling rocks.

[0003] In view of the above, we provide a passive slope rockfall protection net to solve the above problems. Summary of the Invention

[0004] In response to the above situation, the present invention provides a passive slope rockfall protection net. When a rock falls on the net, it causes the net to slide, thereby increasing the length of the net between the main bodies. As the length increases, the net buffers the falling rocks repeatedly.

[0005] A passive slope rockfall protection net includes a column, characterized in that ropes are attached to both the upper and lower sides of the column, and a protective net is attached to the surface of the ropes. A groove is provided on one side of the column to facilitate the sliding of the protective net. A buffer drive mechanism is provided on one side of the groove. The buffer drive mechanism includes a drive column, a buffer spring, a drive disc, and a buffer column. The drive column is rotatably mounted on one side of the column. Buffer springs are provided on both sides of the drive column. A drive disc is integrally mounted on both the upper and lower sides of the drive column. The buffer column is rotatably mounted inside the column. The bottom of the buffer column is attached to the drive column. A rotation control mechanism is provided at the top of the buffer column. A compression buffer mechanism is provided at the top of the column. The compression buffer mechanism includes a compression block, vertical strips, and horizontal strips.

[0006] The beneficial effects of the above technical solution are as follows:

[0007] (1) The protective net designed in this scheme can slide when a rock hits the net, which can increase the length of the net between the main bodies. When the length is increased, the rock is buffered again and again, preventing the rock from impacting the column due to the large potential energy of the first rock, causing damage to the column and failing to protect the downhill slope. The sliding protective net designed in this scheme can automatically increase its length when the rock hits, making it convenient for the rock to move with the protective net. During the movement, the net is buffered, and the impact force generated by the rock is reduced again and again, thereby achieving the effect of protecting the column.

[0008] (2) In this scheme, the driving column is connected to the node of the protective net. The driving column is rotated by the protective net and reset during the rotation process to provide power to the internal mechanism of the column. After the driving column rotates a certain number of times, the column will self-lock the protective net. The buffer springs set on the upper and lower sides of the driving column can buffer the impact of falling rocks on the protective net. The protective net will reset under the action of the buffer springs after moving a certain distance, so that the next node of the protective net can control the driving column to rotate. Finally, it will control the release block to release, thereby achieving the effect of locking the protective net. Attached Figure Description

[0023] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 13 As will be clearly shown in the detailed description of the embodiments, all structural contents mentioned in the following embodiments are based on the accompanying drawings.

[0024] This embodiment provides a passive slope rockfall protection net, as shown in the attached document. Figure 1-2 As shown, this scheme uses the RX-050 passive protective netting, with DO / 08 / 200 flexible steel wire rope netting as the main protective structure, and SO / 2.2 / 50 steel wire mesh screens to form a fence-type protective netting. The upper and lower support ropes are φ16mm double ropes, each with a pressure-reducing ring. Anchor ropes are φ16mm steel ropes for anchoring. The netting height is 3m, and the steel posts are No. 18 I-beams, spaced 4m apart. The total length of the RX-050 passive protective netting is 680m, and the height is 3m. Please refer to the attached instruction manual. Figure 1This design involves sliding the protective netting 3 onto the column 1. The column 1 needs to be fixed to the slope with bolts or concrete to provide stable support. The upper and lower sides of the protective netting 3 overlap with the rope 2. (Both sides of the protective netting 3 have a small opening to prevent the rope 2 from detaching from the netting 3. This opening allows the positioning ring 33 to slide on the rope 2 without affecting the movement of the protective netting 3. The positioning ring 33 has a chamfer for easy access to the top of the protective netting 3.) The design basis of this solution is that the protective netting 3 can slide on the column 1. The rope 2 and one end of the protective netting 3 are slightly extended, depending on the impact force of the falling rocks and the installation method of the column 1. However, one point is mentioned in the instruction manual attached to this solution. Figure 1 The full demonstration was not shown. That is, the ends of the rope 2 and the protective net 3 that extend infinitely need to be welded to the column 1 to give it a buffer length limit. The rope 2 is attached to the column 1 through the positioning ring 33. The rope 2 and the protective net 3 are both made of existing materials, such as steel rope, and can be bent and moved. They are not hard objects, but flexible metals.

[0025] As attached Figure 3-6 As shown, the instruction manual is attached. Figure 3 This is a cut view of one side of column 1. Column 1 in this design is a square-like shape, but with chamfered corners. This view shows the majority of the structural features of this design by cutting symmetrically along the axis of the square. Please see the attached instruction manual. Figure 3 The image shows many wavy lines because of the instruction manual. Figure 3 It's not easy to understand the solution, so the instruction manual is attached. Figure 3 Disassembled for display, as per the instruction manual. Figure 4As shown, the rotating column 5 is mounted on the column body 1, and both its upper and lower sides have buffer springs 6 (the buffer springs 6 are common torsion springs that can be torn and reset). In this design, the protective net 3 uses a square intersection, and the rotating column 5 is positioned exactly at one point of the square. The rotating column 5 blocks the movement of the protective net 3. For the protective net 3 to pass through the rotating column 5, it must pass through this point of the square, causing the rotating column 5 to rotate. After the rotating column 5 rotates by a certain angle, the next set of nodes will arrive at one side of the rotating column 5, waiting to cause the rotating column 5 to rotate again, because the buffer springs 6 of the rotating column 5 will reset after rotation. Therefore, the drive column 5 will rotate back and forth. This force is generated by the impact of falling rocks on the protective netting 3. This design only shows one drive column 5; in reality, a row of drive columns 5 can be installed as needed, arranged side-by-side with an integrated design. Only the vertical width of the drive columns 5 needs to be increased. During rotation, the drive column 5 uses a buffer spring 6 to cushion the force of the falling rocks, ensuring that the force remains relatively stable. This continuously buffers the impact of the falling rocks on the protective netting 3, gradually reducing the force until it completely dissipates. Compared to existing protective netting 3, which is affected by excessive force from falling rocks... Excessive buffering will damage column 1 because it exceeds its bearing capacity, causing it to loosen. This design uses a buffer force less than the column 1's bearing capacity for each buffering action, increasing the number of buffering attempts to gradually buffer the falling rocks until they stop, thus protecting the area below the slope. A buffer column 8 is designed to further enhance the buffering force of this design, with its bottom driven by a drive disc 7. The drive disc 7 is integrated into the upper and lower sides of the drive column 5 and is a ratchet with unidirectional rotation. The bottom of the drive disc 7 has an overlapping block 21. 21 is rotatably set at the bottom of the buffer column 8 and has a No. 1 spring 22 to make the overlapping block 21 overlap on the drive plate 7 (the No. 1 spring 22 is also a torsion spring, so that the overlapping block 21 is always close to the drive plate 7, forming a one-way rotation mechanism, so that when the protective net 3 controls the drive column 5 to rotate, the drive column 5 can drive the buffer column 8 to rotate, and when the drive column 5 returns to its original position in the opposite direction, the drive column 5 slips with the buffer column 8. This requires the buffer column 8 to rotate multiple times to activate the middle and top structures. It also shows that the protective net 3 activates the middle and top structures after sliding a certain length). The middle and top structures will be described in detail in the next section.

[0026] As attached Figure 7-13As shown in the previous paragraph, the middle and top structures are the jacking frame 12 and the compression block 9 of this scheme. To provide some protection for this scheme, if the falling rock still has a lot of power after buffering a certain distance, this scheme is designed with locking devices, such as the jacking frame 12. The jacking frame 12 is controlled by the lifting block 18. The lifting block 18 is threaded on the screw 17, which is integrally mounted on the buffer column 8. The lifting block 18 and the screw 17 form a threaded lifting structure. Therefore, when the screw 17 rotates, the lifting block 18 will rise and fall (support rods are set on both sides of the lifting block 18 to support and slide the lifting block 18, so that it can rise and fall threadily). The rising and falling of the lifting block 18 can drive the first block 19 to rise and fall. The first block 19 and the column A second spring 20 is installed between the body 1 and the column 1. The second spring 20 increases the force required for the screw 17 to rotate, indirectly buffering the impact of falling rocks. The lifting block 18, when moved to a certain position, can drive the jacking frame 12 to move upward. The two extended ends of the jacking frame 12 are locked in the release groove 14. When the jacking frame 12 moves upward, it is equivalent to releasing the release block 13. The release block 13 slides laterally on the column 1. Once the release block 13 is released, the protective net 3 will no longer slide. However, this process requires the column 5 to rotate a certain number of times before it can be started. In practice, the protective net 3 may stop moving before the release block 13 is activated. One side of the release block 13 has a release spring 15, which is attached to the instruction manual. Figure 6 The middle part is in a compressed state and has a certain elastic potential energy. Once released, it can quickly reach the side of the slot 4 to block the protective net 3. The release block 13 in this scheme is the last program. That is, when the column 5 is rotated a certain number of times, the protective net 3 is still moving. At this time, the release block 13 will be released to reach the last program and buffer the falling rocks. There is also a squeezing block 9 designed above the drive frame. There are four squeezing blocks 9 on the top, bottom, left and right sides of the column 1 (if the middle part of the column 1 in this scheme is disassembled, the structure on the top and bottom sides is completely symmetrical. The attached diagram of this scheme shows the top part of the column 1, and another part is symmetrically set below the main body). Before the release block 13 is released, the squeezing block 9 moves first. The squeezing block 9 is slidably set on the vertical bar 10. The movement trajectory of the vertical bar 10 is first horizontal sliding and then diagonal sliding (please see the shape of the drive slot 32, the shape of the drive slot 32 is attached to the instruction manual). Figure 11 As can be seen from the attached manual, Figure 11The viewing angle has been changed for easier observation. The vertical strip 10 has a cylinder on each side, which fits perfectly onto the drive groove 32. Therefore, when the horizontal strip 11 moves laterally, the drive groove 32 causes the pressing block 9 to move laterally and then diagonally. This first pushes the top of the protective net 3, effectively increasing the contact point. The top of the protective net 3 requires a certain amount of force to pass through the pressing block 9 each time. However, the diagonal movement blocks the top of the protective net 3, preventing further movement on the top and bottom sides. Please refer to the attached instruction manual. Figure 2The protective net 3 has a circular block on both the top and bottom that overlaps the rope 2. While the top and bottom of the protective net 3 are restrained, the middle section can continue to slide because the shape of the net 3 can be changed. This makes the net 3 appear as a funnel shape, with the middle recessed and the edges locked, encasing the stone and preventing it from bouncing off. Existing protective nets 3 are rigidly connected to the column 1, resulting in high elasticity, making it easy for stones to pass over them, thus reducing their effectiveness. This design allows the protective net 3 to slide, providing two benefits: firstly, it protects against loosening of the column 1; secondly, it encases the stone, preventing it from bouncing off. To prevent the stone from bouncing back and falling, the wrapping described here is not a complete wrap, but rather forms an impact depression to prevent the stone from bouncing back. To ensure the overall rotational stability of the buffer column 8, this solution includes a push rod 30, which is an electric push rod 30. The function of the push rod 30 is to facilitate the reset of the column 1 when the staff cleans it after an impact. The middle of the buffer column 8 is provided with a slot 27. The direction of the slot 27 is opposite to the direction of the teeth of the drive plate 7. Therefore, after the drive plate 7 drives the buffer column 8 to rotate, it is fixed and cannot be rotated back to its original position. It is like a spring that keeps rotating without resetting. One side of the locking block 28 has a No. 5 spring 29, which is activated when the staff cleans it. The push rod 30 will be activated for retraction. One end of the push rod 30 extends to a block, which drives the locking block 28 to utilize the locking groove 27, facilitating the reset of the buffer column 8. Finally, it should be noted that many structures in this design have limiting functions, such as the vertical bar 10, which slides vertically on one side of the horizontal bar 11, while the horizontal bar 11 slides laterally on the column 1. The corresponding grooves are provided in this design. For example, the internal gear 25 and the transmission wheel 23 also have grooves to facilitate their sliding or rotation. Ropes 2 are attached to both the upper and lower sides of the column 1, and protective nets 3 are attached to the surface of the ropes 2. A groove 4 is provided on one side of the column 1 to facilitate the sliding of the protective net 3. A buffer driving mechanism is provided on one side of the groove 4.
