Description

Technical Field

[0001] The invention relates to the technical field of landslide control, and in particular to a slope supporting device in a landslide control project. Background Art

[0002] Landslide is a geological phenomenon in which rock and soil on a slope slide along a continuous shear failure surface. The main harm caused by landslide to rural areas is the destruction of farmland and houses, injury to people and livestock, damage to forests, roads, agricultural machinery facilities, water conservancy and hydropower facilities, etc., and sometimes even cause devastating disasters to multiple villages.

[0003] The activity intensity of a landslide is mainly related to its scale, sliding speed, sliding distance, accumulated potential energy and generated functions. Generally speaking, the higher the position of the landslide body, the larger its volume, the faster its moving speed and the longer its moving distance, the higher the activity intensity of the landslide and the greater the degree of harm. The greater the slope height difference, the greater the landslide potential energy and the higher the sliding speed of the formed landslide. The openness of the terrain in front of the slope has a great influence on the size of the sliding distance. The wider the terrain, the greater the sliding distance. The openness has a great influence on the size of the sliding distance. The wider the terrain, the greater the sliding distance.

[0004] In order to reduce the harm of landslides to rural areas, landslides will be controlled. At present, interception nets are laid on the slopes during landslide control to intercept stones falling from the landslide. When laying the interception nets, operators need to install the four corners of the interception nets respectively. This installation method has the following shortcomings: At present, the slope of the landslide occupies a large area, which makes the overall area of ​​the interception net larger. When the operator pulls the interception net in the horizontal or vertical direction, due to the weight and volume of the interception net, it is inconvenient for the operator to pull it, which increases the operator's work intensity and affects the speed of landslide control. Summary of the invention

[0005] The purpose of the present invention is to solve the problem of inconvenience in landslide control in the prior art, and to propose a slope supporting device in landslide control engineering.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A slope support device in a landslide control project comprises a fixed base placed at the bottom of the landslide, and an interception net for protecting the landslide is laid on the fixed base, symmetrically arranged cylinders are fixedly installed in the fixed base, and an extension rod is fixedly connected to the output end of the cylinder, a moving block is fixedly installed on the extension rod, and a supporting tube is fixedly installed on the moving block, a guide rod is integrally connected in the supporting tube, and a moving rod is slidably sleeved on the guide rod, the supporting tube and the moving rod are provided with limit clamps for clamping the corners of the interception net, and a moving component for driving the moving rod to rise and fall is installed on the supporting tube.

[0008] Preferably, a support frame is installed on the pin shaft of the support cylinder, and two corresponding support frames are placed with interception plates for protecting against landslides.

[0009] Preferably, the support frame is horizontally arranged at one side of the support tube, and the support frame is a concave structure, and a recess for accommodating the intercepting plate is provided in the support frame.

[0010] Preferably, the fixed base is provided with a positioning column extending into the ground, the extension rods are horizontally arranged at two sides of the fixed base, and the moving block and the extension rods extend to one side outside the fixed base.

[0011] Preferably, the guide rods are vertically arranged at both sides of the fixed base, and the limit clamps and the movable rods extend to the upper end positions outside the supporting tube.

[0014] Preferably, the limiting clamp is a concave structure, and an elastic pressure plate for squeezing the interception net is provided inside the limiting clamp. The elastic pressure plate is tilted, and an extrusion block extending into the mesh of the interception net is provided on the elastic pressure plate. A screw for clamping the interception net is provided inside the limiting clamp.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. The present invention drives two moving blocks to move in opposite directions through the expansion and contraction of the cylinder output end. When the two moving blocks move in opposite directions, they pull the two limit clamps at the lower ends, so that the two limit clamps can stretch the interception net in the horizontal direction, and then the interception net can protect against landslides through the deflection of the support frame.

[0018] To summarize, the present invention drives the two moving blocks to move in opposite directions through the extension and retraction of the cylinder output end. When the two moving blocks move in opposite directions, they pull the two limit clamps at the lower end, so that the two limit clamps can stretch the interception net in the horizontal direction, and then the interception net can protect against landslides through the deflection of the support frame; the motor output end drives the rotating shaft to rotate, so that when the moving rod slides on the guide rod, it drives the two limit clamps at the upper end to move upward, and when the two limit clamps move upward, they can stretch the interception net in the vertical direction, thereby making it more convenient to lay the interception net.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-Figure 5A slope support device in a landslide control project includes a fixed base 1 placed at the bottom of the landslide, and an interception net 10 for protecting the landslide is laid on the fixed base 1. By placing the fixed base 1 at the bottom of the landslide and extending the four corners of the interception net 10 into the limiting clamp 9, the interception net 10 can intercept the soil on the landslide when it is unfolded, so that the operator's own safety is guaranteed when controlling the landslide.

[0027] The limit clamp block 9 is a concave structure, and an elastic pressure plate for squeezing the interception net 10 is arranged inside the limit clamp block 9. The elastic pressure plate is arranged obliquely, and an extrusion block extending into the mesh of the interception net 10 is arranged on the elastic pressure plate. A screw for clamping the interception net 10 is arranged inside the limit clamp block 9. Figure 5 As shown, after the corners of the interception net 10 extend into the limiting clamp 9, the elastic pressure plate can squeeze the corners of the interception net 10, and the squeezing block on the elastic pressure plate can extend into the mesh inside the interception net 10, and then the interception net 10 is wrapped around the screws, making the interception net 10 more convenient to install.

[0028] A support frame 15 is installed on the support cylinder 6, and two corresponding support frames 15 are placed with interception plates 16 for landslide protection. The support frame 15 is horizontally arranged at one side of the support cylinder 6, and the support frame 15 is a concave structure. A recess for receiving the interception plate 16 is provided in the support frame 15. Figure 4 As shown, a recess is provided in the support frame 15 for storing the interception plate 16, and the recess is provided at an angle so that the interception plate 16 is in an inclined state, and can intercept falling stones. By setting the number of the interception plates 16 to two, the interception degree of the interception plates 16 can be further improved.

[0029] A symmetrically arranged cylinder 3 is fixedly installed in the fixed base 1, and an extension rod 4 is fixedly connected to the output end of the cylinder 3, and a moving block 5 is fixedly installed on the extension rod 4. A positioning column 2 extending into the ground is provided on the fixed base 1, and the extension rod 4 is horizontally arranged on both sides of the fixed base 1. By placing the fixed base 1 at the bottom end of the landslide and pressing the fixed base 1, the fixed base 1 drives the positioning column 2 to extend into the ground. After the output end of the cylinder 3 is extended and retracted, the two supporting tubes 6 can be driven to move in the opposite direction. The supporting tubes 6 can move to the positions on both sides of the landslide when moving in the opposite direction. When the two supporting tubes 6 move in the opposite direction, the intercepting net 10 can be stretched in the horizontal direction.

[0030] The moving block 5 and the extension rod 4 extend to one side outside the fixed base 1, and a support tube 6 is fixedly installed on the moving block 5, a guide rod 7 is integrally connected to the support tube 6, and a moving rod 8 is slidably sleeved on the guide rod 7. The guide rod 7 guides the moving rod 8, so that the moving rod 8 can smoothly pull the upper end limit clamp 9 when moving.

[0031] The support tube 6 and the movable rod 8 are provided with limit clamps 9 for clamping the corners of the intercepting net 10, and the guide rods 7 are vertically arranged on both sides of the fixed base 1. The limit clamps 9 and the movable rod 8 extend to the upper end position outside the support tube 6. By setting the number of limit clamps 9 to four, the four limit clamps 9 can clamp the four corners of the intercepting net 10, so that the intercepting net 10 does not need to be manually pulled by the operator when extended, further reducing the operator's workload.

[0032] A moving assembly for driving the moving rod 8 to move up and down is installed on the supporting cylinder 6 .

[0033] The moving component includes a driven rack 11 fixedly mounted on the moving rod 8, and a motor 12 is fixedly mounted in the support tube 6. When the motor 12 is energized, it drives the rotating shaft 13 to rotate. This technical solution is a prior art and will not be elaborated on here. The output end of the motor 12 is fixedly connected to the rotating shaft 13 which is transmission-connected to the driven rack 11. The rotating shaft 13 is horizontally arranged, and a driving gear 14 meshing with the driven rack 11 is fixedly mounted on the rotating shaft 13. The rotating shaft 13 drives the driving gear 14 to rotate. When the driving gear 14 rotates, it pulls the meshing driven rack 11, so that the driven rack 11 drives the moving rod 8 and the limit clamp 9 to move upward. When the two limit clamps 9 at the upper end move upward, the interception net 10 can be stretched in the vertical direction, thereby making it more convenient to lay the four corners of the interception net 10.

[0034] The present invention can be explained by the following operation mode:

[0035] Place the fixed base 1 at the lower end of the landslide, and press the fixed base 1 so that the fixed base 1 drives the positioning column 2 to extend into the ground;

[0036] The four corners of the interception net 10 extend into the limiting clamp block 9;

[0037] The output end of the cylinder 3 is extended and retracted to drive the extension rod 4 to slide in the fixed base 1, and the extension rod 4 drives the moving block 5 and the support tube 6 to move horizontally and move to the positions on both sides of the landslide, so that the interception net 10 can be horizontally extended;

[0038] The output end of the motor 12 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the driving gear 14 to pull the meshing driven rack 11, so that the driven rack 11 drives the moving rod 8 to slide on the guide rod 7. When the moving rod 8 slides, it drives the upper end limit clamp 9 and the interception net 10 to move upward, so that the interception net 10 can be extended in the vertical direction;

[0039] Press the support frame 15 to make the support frame 15 deflect with the pin point as the fulcrum, and then place the interception plate 16 between the two support frames 15;

[0040] The operator is able to perform slope management.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
