Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, and in particular to a slope reinforcement and rockfall prevention net. Background Technology

[0002] Slope reinforcement and rockfall prevention netting, also known as slope protection netting, is a device used to prevent geological disasters such as landslides and rockfalls. It can effectively intercept natural disasters such as rockfalls, flying rocks, avalanches, and debris flows, and protect roads and buildings from damage.

[0003] When installing slope protection netting, it is necessary to use connectors such as pins to fix the U-shaped fixing blocks at the edge of the netting to the slope. However, the U-shaped fixing blocks are fixed to the edge of the netting, but not all positions on the slope are suitable for pins. For example, it is not convenient to insert pins on hard rocks. If the U-shaped fixing block is located on one side of the rock, it is not convenient to fix the netting, which will reduce the stability of the connection between the netting and the slope. Summary of the Invention

[0004] This utility model proposes a slope reinforcement and rockfall prevention net to address the problem that U-shaped fixing blocks are fixed to the frame of the protective net. If the U-shaped fixing block is located on one side of the rock, it is not convenient to fix the protective net, which will reduce the stability of the connection between the protective net and the slope.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a slope reinforcement and rockfall prevention net, comprising a frame, an inner net and an outer net fixedly installed on the inner wall of the frame, a plurality of U-shaped fixing blocks provided on both sides of the frame, an adjustment device provided between the U-shaped fixing blocks and the frame, the adjustment device fixing the U-shaped fixing blocks that can move on one side of the frame by setting threaded pins and screw holes.

[0006] The effect achieved by the above components is as follows: by setting threaded pins and screw hole blocks, the U-shaped fixing block is pushed to move on one side of the frame. The U-shaped fixing block will drive the threaded pin to rotate, which in turn rotates the screw hole block, so that one side of the screw hole block abuts against one side of the frame. The screw hole block can fix the threaded pin and the frame, and thus fix the U-shaped fixing block and the frame. This makes it easier to adjust the position of the U-shaped fixing block according to the actual situation of the slope, which helps to improve the stability of the connection between the protective net and the slope.

[0007] Preferably, the adjusting device includes a connecting plate, with both ends of the connecting plate fixedly installed on the side of the U-shaped fixing block that is close to each other. The connecting plate is slidably installed on the inner wall of one side of the frame. A threaded pin is fixedly installed in the middle of one side of the connecting plate. The threaded pin is slidably inserted into the inner wall of the frame. A threaded hole block is threadedly connected to the outer surface of the threaded pin.

[0008] The effect achieved by the above components is as follows: the U-shaped fixing block is pushed to move on one side of the frame, and the U-shaped fixing block, the connecting plate, and the threaded pin slide synchronously on the inner wall of the frame. When the U-shaped fixing block reaches the appropriate position on the frame, the screw hole block is rotated so that one side of the screw hole block abuts against the frame, and the screw hole block can fix the edge and the connecting plate.

[0009] Preferably, a rubber pad is fixedly installed on the side of the screw hole block near the connecting plate, and the rubber pad is sleeved on the outer surface of the threaded pin.

[0010] The effect achieved by the above components is that by setting a rubber pad, one side of the screw hole block can be replaced by the other side of the frame, and the friction between the screw hole block and the frame can be increased, which helps to prevent the screw hole block from easily loosening.

[0011] Preferably, an operating block is fixedly installed on the top of the screw hole block, the operating block is sleeved on the outer surface of the threaded pin, and the outer surface of the operating block is provided with protrusions.

[0012] The effect achieved by the above components is as follows: by setting the operating block, rotating the operating block can drive the screw hole block to rotate. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0013] Preferably, a ring is fitted on the outer surface of the rubber pad, and the ring is disposed between the operating block and the frame.

[0014] The effect achieved by the above components is that, by setting up the ring, the rubber pad can be shielded and protected under the joint action of the auxiliary blocks, which helps to slow down the aging of the rubber pad.

[0015] Preferably, a circular block is fixedly installed at one end of the threaded pin, and the outer diameter of the circular block is larger than the outer diameter of the threaded pin.

[0016] The effect achieved by the above components is that by setting up a round block, the round block can block one end of the threaded pin, which helps to prevent the threaded hole block from easily disengaging from the threaded pin due to misoperation.

[0017] Preferably, two buckles are symmetrically slidably installed on one side of the connecting plate, and the same spring is fixedly installed on the side of the two buckles that are close to each other.

[0018] The effect achieved by the above components is as follows: pushing the two locking blocks away from the inner walls of the frame causes them to compress the spring, causing it to deform. This deforms the spring and pushes the connecting plate to move on one side of the frame, which in turn moves the U-shaped fixing block synchronously. When the U-shaped fixing block moves to the appropriate position, the force applied to the two locking blocks is removed, and the spring returns to its original position, causing the buckle to move until its outer surface abuts against the inner side of the frame. This provides auxiliary fixation between the connecting plate and the frame, improving the stability of the connection between the U-shaped fixing block and the frame. It also facilitates the quick fixation of the U-shaped fixing blocks using screw holes in subsequent processes.

[0019] Preferably, the spring has a round rod inside, and both buckles are slidably mounted on the outer surface of the round rod.

[0020] The effect achieved by the above components is that by setting the round rod, the round rod can limit and guide the spring, which helps to prevent the spring from easily bending during deformation.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting a threaded pin and a screw hole block, the U-shaped fixing block is pushed to move on one side of the frame. The U-shaped fixing block will drive the threaded pin to rotate, thus rotating the screw hole block so that one side of the screw hole block abuts against one side of the frame. The screw hole block can fix the threaded pin and the frame, thereby fixing the U-shaped fixing block and the frame. This makes it easier to adjust the position of the U-shaped fixing block according to the actual situation of the slope, which helps to improve the stability of the connection between the protective net and the slope.

[0029] Example 1, referring to Figures 1-3 As shown, this embodiment discloses a slope reinforcement and rockfall prevention net, including a frame 1. An inner net 2 and an outer net 3 are fixedly installed on the inner wall of the frame 1. Several U-shaped fixing blocks 4 are provided on both sides of the frame 1. An adjustment device 5 is provided between the U-shaped fixing blocks 4 and the frame 1. The adjustment device 5 fixes the U-shaped fixing blocks 4, which can move on one side of the frame 1, by setting threaded pins 52 and screw holes 53. By setting threaded pins 52 and screw holes 53, the U-shaped fixing blocks 4 are pushed to move on one side of the frame 1. The U-shaped fixing blocks 4 will drive the threaded pins 52 to rotate, thereby rotating the screw holes 53, so that one side of the screw holes 53 abuts against one side of the frame 1. The screw holes 53 can fix the threaded pins 52 and the frame 1, and thus fix the U-shaped fixing blocks 4 and the frame 1. This makes it easy to adjust the position of the U-shaped fixing blocks 4 according to the actual situation of the slope, which is beneficial to improving the stability of the connection between the protective net and the slope.

[0030] Reference Figure 2 and Figure 3 As shown, the adjusting device 5 includes a connecting plate 51. Both ends of the connecting plate 51 are fixedly installed on the side of the U-shaped fixing block 4 that is close to each other. The connecting plate 51 is slidably installed on the inner wall of one side of the frame 1. A threaded pin 52 is fixedly installed in the middle of one side of the connecting plate 51. The threaded pin 52 is slidably inserted into the inner wall of the frame 1. A threaded hole block 53 is threadedly connected to the outer surface of the threaded pin 52. Pushing the U-shaped fixing block 4 to move on one side of the frame 1 causes the U-shaped fixing block 4 to slide synchronously with the connecting plate 51 and the threaded pin 52 on the inner wall of the frame 1. When the U-shaped fixing block 4 is in motion... After block 4 reaches the appropriate position on frame 1, rotate screw hole block 53 so that one side of screw hole block 53 abuts against frame 1, thus fixing screw hole block 53 between the edge and connecting plate 51. A rubber pad 54 is fixedly installed on the side of screw hole block 53 near connecting plate 51. The rubber pad 54 is sleeved on the outer surface of threaded pin 52. By setting rubber pad 54, one side of screw hole block 53 can abut against one side of frame 1, and the friction between screw hole block 53 and frame 1 can be increased, which helps to prevent screw hole block 53 from easily loosening.

[0031] Reference Figure 2 and Figure 3As shown, an operating block 55 is fixedly installed on the top of the screw hole block 53. The operating block 55 is sleeved on the outer surface of the threaded pin 52. The outer surface of the operating block 55 is provided with protrusions. By setting the operating block 55, rotating the operating block 55 can drive the screw hole block 53 to rotate. At the same time, the protrusions on the outer surface of the operating block 55 can effectively increase the friction of the outer surface of the operating block 55, which has an anti-slip effect when rotating the operating block 55. A ring 56 is sleeved on the outer surface of the rubber pad 54. The ring 56 is set between the operating block 55 and the frame 1. By setting the ring 56, with the joint action of the auxiliary block, the rubber pad 54 can be shielded and protected, which helps to slow down the aging of the rubber pad 54.

[0032] Reference Figure 2 and Figure 3 As shown, a round block 510 is fixedly installed at one end of the threaded pin 52. The outer diameter of the round block 510 is larger than the outer diameter of the threaded pin 52. By setting the round block 510, the round block 510 can block one end of the threaded pin 52, which helps to prevent the screw hole block 53 from easily disengaging from the threaded pin 52 due to misoperation.

[0033] Reference Figure 4 and Figure 5 As shown, two latches 57 are symmetrically slidably mounted on one side of the connecting plate 51. A spring 58 is fixedly mounted on the side of the two latches 57 that is close to each other. Pushing the two latches moves them away from the sides of the inner wall of the frame 1. Simultaneously, the two latches compress the spring 58, causing it to deform. This pushes the connecting plate 51 to move on one side of the frame 1, which in turn moves the U-shaped fixing block 4 synchronously. When the U-shaped fixing block 4 moves to the appropriate position, the force applied to the two latches is removed, causing the spring 58 to reset and move the latches 57 inward. The movement continues until the outer surface of the buckle 57 abuts against the inner side of the frame 1, which can assist in fixing the connecting plate 51 and the frame 1, improve the stability of the connection between the U-shaped fixing block 4 and the frame 1, and facilitate the quick fixing of the U-shaped fixing block 4 through the screw hole block 53 in the subsequent process; the spring 58 is provided with a round rod 59 inside, and the outer surface of the round rod 59 is slidably installed on both buckles 57. By setting the round rod 59, the round rod 59 can play a role in limiting and guiding the spring 58, which helps to prevent the spring 58 from easily bending during deformation.

[0034] Working principle: Pushing the two locking blocks away from the inner walls of the frame 1 causes the spring 58 to deform, which in turn pushes the connecting plate 51 to move on one side of the frame 1. This causes the U-shaped fixing block 4 to move synchronously. When the U-shaped fixing block 4 moves to the appropriate position, the force applied to the two locking blocks is removed, and the spring 58 returns to its original position. This causes the buckle 57 to move until its outer surface abuts against the inner side of the frame 1, thus providing auxiliary fixation between the connecting plate 51 and the frame 1. Then, rotating the operating block 55 causes the screw hole block 53 to rotate, making the rubber pad 54 on one side of the screw hole block 53 abut against the frame 1. This fixes the screw hole block 53 between the edge and the connecting plate 51, allowing for adjustment of the position of the U-shaped fixing block 4 according to the actual slope conditions. The ring 56, with the help of the auxiliary blocks, can shield and protect the rubber pad 54, which helps to slow down the aging of the rubber pad 54.
