Description

Technical Field

[0001] The invention relates to the technical field of slope protection structures, in particular to a black rock series slope protection structure. Background Art

[0002] Black rock slopes usually refer to slopes or steep slopes composed of black rocks, mainly composed of sedimentary rocks such as shale, sandstone or basalt, etc. Black or dark rocks. The stability of black rock slopes will be affected by many factors. Through in-depth investigation of the weathering area of ​​black rock systems, it was found that black rock systems are extremely susceptible to weathering when exposed to the surface, causing large amounts of toxic heavy metals to leach into the surface soil, water and plant systems, thereby affecting crop safety and human health. It has great investigation and research value. If the slope is composed of shale, the stratification and weathering of the shale may make the slope more prone to landslides.

[0003] After searching, it was found that the prior art publication number is CN 212895971 U, which discloses a mine slope gravel interception device, which relates to the field of hillside protection. The mine slope gravel interception device includes a base plate and an interception net. The interception net is set on the top of the base plate. The bottom of the base plate is fixedly connected to a plug rod. There are support rods on both sides of the interception net. The top of the support rod is provided with an extension rod. The extension rod and the support rod are slidably connected. One side of the extension rod is provided with a fixed column. The other side of the fixed column is provided with a hinged rod. The support rod is provided with a pin assembly inside. The bottom of the support rod is provided with a buffer assembly. The bottom of the base plate is provided with a support assembly. The solution is provided with a straight tube, a straight rod and a second spring on the back of the support rod. When the support rod moves, it will first push the straight rod, and the straight rod will retract into the interior of the straight tube. At this time, the second spring is compressed, which can buffer part of the impact force.

[0004] Therefore, based on the above search and combined with the existing technology, during the long-term use of the barrier net, it is inevitable that it will break due to long-term wind and sun exposure, and the fallen rocks that are picked up will roll out through the holes.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figure 1 、 2 , 3, 10, a black rock slope protection structure, comprising an embedded part 1, a stabilizing shell 102 fixedly welded to the upper end of the embedded part 1, a connector 2 is provided above the stabilizing shell 102, a fixing ring 202 is fixedly installed on the upper rear end of the connector 2 by bolts, and a plurality of embedded parts 1 are provided, distributed in a rectangular array (such as Figure 1 As shown in FIG), a blocking net 3 is provided at the center, and the blocking net 3 is fixedly connected to the fixing ring 202. A plurality of movable holes are provided on the upper end of the connector 2, and a guide ring 201 is slidably installed in each movable hole. Specifically, a plurality of signal nets 4 are staggered through the interior of the blocking net 3, and the signal nets 4 are fixedly connected to the guide ring 201 respectively (the specific distribution is shown in FIG). Figure 10 As shown), the blocking net 3 and the signal net 4 are both made of steel wire. The staggered signal nets 4 are inserted inside the blocking net 3. When a rock falls, the signal net 4 and the blocking net 3 intercept the rock together.

[0038] See also Figure 2 、 3, 4, 6, the inner end of the embedded part 1 is sleeved with an abutment tube 104, which is gradually reduced from top to bottom, and the inner end of the abutment tube 104 is sleeved with an inner casing 105, and a plurality of stable bases 301 are fixedly installed on the inner bottom end of the inner casing 105. The plurality of stable bases 301 are distributed in a ring shape, and a disconnection alarm device for detecting the disconnection of the blocking net 3 and the signal network 4 is provided above the plurality of stable bases 301. A stabilizing sleeve 401 is fixedly installed on the inner bottom end of the embedded part 1, and the stabilizing sleeve 401 and the connector 2 are on the same axis;

[0039] like Figure 4 、 5 6. The inner end of the connector 2 is fixedly installed with a partition plate 207, and the bottom end of the partition plate 207 is fixedly welded with a center rod 203. The bottom end of the center rod 203 is fixedly installed with a plurality of socket blocks 205. The socket blocks 205 are distributed in a ring shape. The inner end of the stabilizing sleeve 401 is penetrated by a seat pin 404, and the socket block 205 is sleeved on the upper end of the seat pin 404. Specifically, a card slot is opened at the upper end of the seat pin 404, and the socket block 205 is sleeved in the card slot on the seat pin 404. In order to achieve stability after the socket block 205 is clamped on the seat pin 404, a locking sleeve rod 204 is sleeved on the outer surface of the center rod 203. The locking sleeve rod 204 04 moves downward and is sleeved on the outer surface of the sleeve block 205, which can prevent the center rod 203 from being suddenly forced to move upward, so that the sleeve block 205 is separated from the outer surface of the seat pin 404. A positioning block 206 is fixedly installed on the outer surface of the center rod 203, and a limiting slide groove is provided on the outer surface of the locking sleeve rod 204. The positioning block 206 is passed through the limiting slide groove. The locking sleeve rod 204 can slide up and down on the outer surface of the center rod 203 to avoid rotation on the outer surface of the center rod 203. A plurality of holes are provided at the inner end of the partition plate 207, and a plurality of movable sleeves 209 are passed through the holes, and the plurality of movable sleeves 209 are distributed in a ring shape.

[0040] Example 2: Please refer to Figure 6 、 7 A black rock slope protection structure, based on Example 1, a line break alarm device includes a signal transmitting terminal 304, which has both signal transmission alarm and data processing functions. It is a prior art and will not be described in detail here. The signal transmitting terminal 304 is fixedly mounted on the front end of a stable base 301, and a stable shaft 306 is rotatably mounted on the upper end of the stable base 301. A torsion spring 307 is wound around the outer surface of the stable shaft 306. A spiral rod 303 is fixedly mounted on the upper end of the stable base 301, and a deceleration rope 308 is wound around the outer surface of the spiral rod 303. The free end of the torsion spring 307 is fixedly connected to the end of the deceleration rope 308 near the stable shaft 306.

[0041] An angle sensor 305 is bolted to the upper end of the stabilizing base 301, and the output end of the angle sensor 305 is fixedly connected to the stabilizing shaft 306. The angle sensor 305 is electrically connected to the signal transmitting terminal 304 via a wire. A latch 302 is slidably mounted on the upper end of the spiral rod 303, and the free end of the deceleration rope 308 is fixedly connected to the latch 302.

[0042] When the movable sleeve 209 is moved upward, the two adjacent clamping plates 213 are squeezed against each other by the slope of the triangular block 212, thereby realizing that the triangular hook at the inner end of the clamping plate 213 hooks the abutment block on the outer surface of the latch pin 302 and realizes fixation. More specifically, the guide rope 208 is fixedly connected to one end of the guide ring 201 close to the partition plate 207;

[0043] When the pin 302 is pulled upward, the stabilizing shaft 306 is rotated via the deceleration rope 308 and the torsion spring 307. Since the force exerted by the rockfall on the barrier net 3 or the signal net 4 is several times greater than the rockfall's own gravity, rigid interception can easily cause the cable to break. The friction coefficient between the deceleration rope 308 and the spiral rod 303 is proportional to the number of turns of the deceleration rope 308 wound around the outer surface of the spiral rod 303 and the winding radius. The more turns the deceleration rope 308 is wound, the greater the frictional resistance, resulting in a "rope friction effect," which can be described by the "Kapusta formula" as follows:

[0044]

[0045] in, is the greater tension in the direction of rope sliding (the force that will cause the rope to slide), It is the smaller tension in the direction of rope sliding. is the coefficient of friction between the rope and the post, is the contact angle between the rope and the column (in radians). If the rope is wrapped around the column multiple times, the contact angle will be the sum of the contact angles per turn, e.g. if the rope is wound around the pole once, then If it goes around twice, then By analogy, it is worth noting that the above calculations are all performed by the processor inside the signal transmitting terminal 304;

[0046] Then, when the signal network 4 is subjected to force, the guide ring 201 and the guide rope 208 instantly pull the deceleration rope 308, and the speed of the guide rope 208 gradually slows down under the action of friction until it stops.

[0047] like Figure 4 、 6 As shown in , 7, the movable sleeve 209 is connected to the partition plate 207 by the abutment spring 210. When the blocking net 3 is broken and the signal net 4 is not broken, the force applied to the signal net 4 is much greater than before, and the angle sensor 305 starts to compare the initial rotation angle of the stabilizing shaft 306 and the current rotation angle, and judges the speed of change of the rotation angle through the processor inside the signal transmitting terminal 304. When the blocking net 3 and the signal net 4 are broken together, the movable sleeve 209 rebounds under the action of the abutment spring 210, and the deceleration rope 308 is no longer subjected to the pulling force, and the torsion spring 307 drives the stabilizing shaft 306 to rotate under the action of the elastic force, and the signal transmitting terminal 304 detects an obvious rotation angle through the angle sensor 305, and then judges that the blocking net 3 and the signal net 4 are broken, and starts to transmit a signal, waiting for the staff to arrive for repair.

[0048] When the rock falls onto the barrier net 3, it is transmitted through the signal network 4, causing the stabilizing shaft 306 to deflect slightly. At this time, the torque, the tension T of the torsion spring 307 and the rotation angle are determined. There is a linear relationship between:

[0049]

[0050] in, is the small rotation angle of the rotating shaft, T is the tension applied by the torsion spring 307 on the stabilizing shaft 306, r is the radius of the stabilizing shaft 306, and k is the stiffness coefficient of the stabilizing shaft 306;

[0051] Once the signal network 4 breaks, the force applied to the stabilizing shaft 306 disappears suddenly, and the stabilizing shaft 306 loses its balance force, resulting in a large angle change. At this time, the initial torque of the stabilizing shaft 306 is , the rotation angle change of the stabilizing shaft 306 is expressed as:

[0052]

[0053] The signal transmitting terminal 304 detects the angle change of the stable axis 306 through the angle sensor 305 to determine whether the signal network 4 is broken. To this end, an angle threshold is set. , used to distinguish normal rotation from large rotation caused by fracture. If , it is judged that the signal network 4 may be broken;

[0054] In order to improve the accuracy of the system and avoid misjudgment, the sensitivity of the angle sensor 305 is adjusted by changing the threshold setting of the angle sensor 305 to optimize:

[0055]

[0056] in, is an adjustment coefficient, usually slightly greater than 1, to ensure that small rotations during normal operation are not mistakenly interpreted as a break in the signal network 4. It is worth noting that the above calculations are all performed by the processor inside the signal transmitting terminal 304;

[0057] See also Figure 3 、 6 , a plurality of sliding holes are provided on the outer surface of the abutment tube 104, and a fixed block is fixedly installed on the outer surface of the inner casing 105, and the fixed block is fixedly connected to the stabilizing shell 102 after passing through the sliding holes, and a plurality of rectangular holes are provided on the outer surface of the embedded part 1, and an expansion rod 101 is provided in the rectangular hole, and the expansion rod 101 is rotatably connected to the embedded part 1, and an arc block is fixedly installed on one end of the expansion rod 101 close to the abutment tube 104, and when the abutment tube 104 moves downward, the arc block is squeezed to push the expansion rod 101 toward the end away from each other, thereby increasing the contact area with the ground and increasing the friction, making the embedded part 1 more stable, and power-assist pedals 103 are slidably installed on the left and right ends of the stabilizing shell 102, and the power-assist pedals 103 are fixedly connected to the abutment tube 104;

[0058] See also Figure 8 、 9 A buffer rope 402 is wound around the outer surface of the stabilizing sleeve 401. A through hole is formed on the outer surface of the stabilizing sleeve 401. The free end of the buffer rope 402 passes through the through hole and is fixedly connected to the seat pin 404. The seat pin 404 and the stabilizing sleeve 401 are connected via a buffer spring 403. The more turns the buffer rope 402 is wound around the stabilizing sleeve 401, the greater the friction between the buffer rope 402 and the stabilizing sleeve 401, thereby providing a sufficiently large pulling force on the connector 2. The friction force is also calculated using the "Kapusta formula", which will not be elaborated here.

[0059] like Figure 9As shown, the outer surfaces of the stabilizing shell 102 and the inner casing 105 are both provided with through holes, and a driving rod 106 is rotatably installed in the through holes. A crown gear 107 is fixedly installed on the end of the driving rod 106 close to the locking sleeve rod 204, and a passive rack 211 is fixedly installed on the end of the locking sleeve rod 204 close to the driving rod 106. The crown gear 107 is meshed with the passive rack 211. When the driving rod 106 rotates, the locking sleeve rod 204 is driven to move upward or downward through the meshing action of the crown gear 107 and the passive rack 211. A handle that is easy for the operator to grasp is fixedly installed on the end of the driving rod 106 away from the crown gear 107, and the driving rod 106 can be driven to rotate by shaking the handle.

[0060] The working principle of the present invention is:

[0061] When in use, the embedded part 1 is placed in a pre-prepared pit, and then the power pedal 103 is stepped on to make the abutment tube 104 move downward. During the downward movement of the abutment tube 104, the expansion rod 101 is pushed toward the end away from each other by squeezing the arc block, thereby increasing the contact surface with the ground, making the friction force greater, and then the blocking net 3 and the signal net 4 are covered on the outer surface of the rock, and the blocking net 3 and the signal net 4 are fixedly installed on the fixing ring 202 and the guide ring 201 respectively, and then the connector 2 is inserted into the inner casing 105;

[0062] At the same time, the sleeve block 205 is sleeved on the upper end of the seat pin 404, and then the driving rod 106 is driven to rotate by the handle. The rotating driving rod 106, under the meshing action of the crown gear 107 and the passive rack 211, causes the locking sleeve rod 204 to move downward and wrap around the sleeve block 205.

[0063] At this time, the movable sleeve 209 is sleeved on the outer surface of the latch 302, so that the triangular block 212 abuts between two adjacent clamping plates 213. When the movable sleeve 209 is moved upward by pulling the guide ring 201, the slope of the triangular block 212 squeezes the two adjacent clamping plates 213 against each other, thereby enabling the triangular hooks at the inner ends of the clamping plates 213 to hook onto the abutting blocks on the outer surface of the latch 302, thereby securing the latch 302.

[0064] The falling rolling stones will be intercepted by the blocking net 3 and the signal net 4. When the blocking net 3 or the signal net 4 breaks, it means that the falling rocks have fallen off. The signal transmitting terminal 304 will send an alarm signal in time to prompt nearby staff to evacuate the scene urgently. The maintenance personnel can accurately determine where the blocking net 3 is broken through the receiving terminal in their hands.

[0065] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
