Description

Technical Field

[0001] This utility model relates to the technical field of slope protection facilities, and specifically to a slope protection device. Background Technology

[0002] To prevent geological disasters on slopes (such as landslides and rockfalls), slope protection facilities are required. Slope protection facilities include active protection methods and passive protection methods.

[0003] Active protection methods involve covering the slope with various flexible nets, primarily steel wire rope nets, to limit the weathering and erosion of the slope's rock and soil or the collapse of dangerous rocks, or to control the movement of falling rocks within a certain range.

[0004] Passive protection methods mainly involve connecting steel columns and protective netting structures to form a whole, creating surface protection for the protected area, thereby preventing the collapse of rocks and soil and playing a role in slope protection.

[0005] See Figure 1 The current passive protection method includes multiple steel columns 2, with two adjacent steel columns 2 connected by a protective net structure 3, and the upper end of the steel column 2 connected to the anchor rod 5 by the anchor rope 4. The anchor rod 5 is fixed to the slope 1 by cast-in-place concrete.

[0006] See Figure 1 When loose rocks 6 roll down to the bottom of slope 1, they will be blocked by the net 34. Because the space on the side of the net 34 facing slope 1 is limited, it is difficult to accommodate cleaning equipment (such as excavators and forklifts) to enter, thus making it inconvenient to clean the rocks 6.

[0007] How to easily clear rocks blocked by the protective net structure is a technical problem that needs to be solved. Utility Model Content

[0008] To address the aforementioned shortcomings of existing technologies, this invention proposes a slope protection device that can facilitate the clearing of rocks blocked by the protective netting structure.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] A slope protection device includes multiple steel columns, with adjacent steel columns connected by a protective net structure. The lower end of each steel column is provided with two movable seats and two height adjustment structures. One height adjustment structure is used to adjust the height of one movable seat. The protective net structure includes an upper support rope, a lower support rope, and a net body. The upper ends of two adjacent steel columns are connected by the upper support rope, and the movable seats at the lower ends of two adjacent steel columns are connected by the lower support rope. The upper support rope is connected to the lower support rope through the net body.

[0011] Furthermore, the height adjustment structure includes a lead screw and a fixing component. Both the upper and lower ends of the lead screw are rotatably connected to the steel column. The movable seat is threadedly connected to the lead screw and slidably connected to the steel column in the vertical direction. The top of the lead screw is provided with a hexagonal prism.

[0012] Furthermore, the fixing component includes a ring seat, a support, and a fastener. The ring seat is located on the upper part of the lead screw. The ring seat has multiple protrusions on its circumference and a recess between two adjacent protrusions. A support is located on one side of the ring seat and is connected to the steel column. A fastener is threaded onto the support and is inserted into the recess.

[0013] Furthermore, the upper end of the steel column is provided with a connecting column, and both the connecting column on the side away from the steel column and the movable seat on the side away from the steel column are provided with limiting plates.

[0014] Furthermore, the upper support rope has an upper loop at its end, which is fitted onto the connecting column, and the lower support rope has a lower loop at its end, which is fitted onto the movable seat.

[0015] Furthermore, the protective net structure also includes a longitudinal support rope, with longitudinal loops at both the upper and lower ends. The upper longitudinal loop of the longitudinal support rope is fitted onto the connecting post, and the lower longitudinal loop of the longitudinal support rope is fitted onto the movable seat. The side of the net body is connected to the longitudinal support rope.

[0016] The beneficial effects of this utility model are:

[0017] 1. Because each steel column is equipped with two movable seats and two height adjustment structures at its lower end, with each height adjustment structure adjusting one movable seat, the lower end of the netting between two adjacent steel columns can be raised independently, while adjacent netting sections remain in their original state, thus maintaining the protective function of adjacent netting sections. When clearing rocks blocked by the netting, only the lower end of the corresponding netting section needs to be raised. After the lower end of the netting section blocking the rock is raised, the rock can be exposed from the side of the netting section away from the slope, making it convenient for workers to drive the clearing equipment to remove the rock from the side of the netting section away from the slope, thereby facilitating rock removal.

[0018] 2. The height adjustment structure of this utility model can be used with existing electric wrenches. The electric wrench drives the lead screw in the height adjustment structure to rotate, thereby adjusting the height of the moving seat, which can improve the height adjustment efficiency and save manpower.

[0019] 3. By setting a fixed component in the height adjustment structure, the screw rotation can be prevented from being driven due to accidental contact, which can improve the stability of the screw when it stops rotating, and thus improve the stability of the moving seat in maintaining the current height.

[0020] 4. The limiting plate on the connecting post is used to prevent the upper rope loop and the longitudinal rope loop from detaching from the connecting post, which can improve the reliability of the upper rope loop and the longitudinal rope loop on the connecting post.

[0021] 5. The limiting plate on the moving seat is used to prevent the lower rope loop and the longitudinal rope loop from detaching from the moving seat, which can improve the reliability of the lower rope loop and the longitudinal rope loop on the moving seat.

[0022] 6. The periphery of the net can be supported by the upper support rope, the lower support rope and the longitudinal support rope, which can improve the strength of the periphery of the net. Attached Figure Description

It is worth noting that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings. They are used for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0044] Example:

[0045] See Figure 12 A slope protection device includes multiple steel columns 2, with adjacent steel columns 2 connected by a protective net structure 3.

[0046] See Figure 3 or Figure 8 A connecting column 21 is welded and fixed to the upper end of the steel column 2. A limit plate 22 is welded and fixed to the connecting column 21 on the side opposite to the steel column 2.

[0047] See Figures 2 to 5 The lower end of the steel column 2 is equipped with two movable seats 23 and two height adjustment structures 7. One height adjustment structure 7 is used to adjust the height of one movable seat 23.

[0048] See Figure 4 The height adjustment structure 7 includes a lead screw 71. Both ends of the lead screw 71 are rotatably connected to the steel column 2 via bearing seats 711, and a hexagonal prism 712 is welded and fixed to the top of the lead screw 71. See also... Figure 5The movable seat 23 is threadedly connected to the lead screw 71. The movable seat 23 slides in a vertical direction with the side wall of the steel column 2 on the side close to the steel column 2. The movable seat 23 is also welded and fixed with a limit plate 22 on the side away from the steel column 2.

[0049] See Figure 4 The height adjustment structure 7 also includes a fixing component. The fixing component includes a ring seat 72, a support 73, and fasteners. The ring seat 72 is welded and fixed to the upper part of the lead screw 71. Multiple protrusions 721 are provided on the periphery of the ring seat 72, and the protrusions 721 and the ring seat 72 are integrally formed. A recess 722 is provided between two adjacent protrusions 721. The support 73 is located on one side of the ring seat 72 and is welded and fixed to the steel column 2. The fastener is a screw 74, which is threaded into a screw hole on the support 73. One end of the screw 74 is inserted into the recess 722, and the other end of the screw 74 is welded and fixed to an operating rod 741.

[0050] The working process of adjusting the height of the movable seat 23 using the height adjustment structure 7 is as follows:

[0051] S1. The worker screws the screw 74 outwards, causing the screw 74 to disengage from the recess 722, so that the ring seat 72 will not be obstructed by the screw 74 when it rotates with the lead screw 71.

[0052] S2. The worker places the hexagonal socket of the electric wrench onto the hexagonal prism 712. The electric wrench drives the hexagonal socket to rotate clockwise, which in turn drives the hexagonal prism 712 to rotate clockwise. The hexagonal prism 712 drives the lead screw 71 to rotate clockwise. The movable seat 23, which is threadedly connected to the lead screw 71 and slides against the side wall of the steel column 2, moves upward along the steel column 2, thereby increasing the height of the movable seat 23.

[0053] Conversely, when the electric wrench drives the hexagonal socket to reverse, the hexagonal socket drives the hexagonal prism 712 to reverse, the hexagonal prism 712 drives the lead screw 71 to reverse, and the movable seat 23, which is threadedly connected to the lead screw 71 and slides with the side wall of the steel column 2, moves down along the steel column 2, thereby reducing the height of the movable seat 23.

[0054] S3. After adjusting the height of the movable seat 23, the worker removes the hexagonal socket of the electric wrench from the hexagonal prism 712; the worker then reverses the screw 74 so that the screw 74 is reinserted into the recess 722. At this time, the ring seat 72 is limited by the screw 74, which can prevent the ring seat 72 from rotating, thereby preventing the lead screw 71 from rotating. After the lead screw 71 stops rotating, the current height of the movable seat 23 can be stabilized.

[0055] As can be seen from the above process of adjusting the height of the movable seat 23, the height adjustment structure 7 of this embodiment can be used with an existing electric wrench. The electric wrench drives the lead screw 71 in the height adjustment structure 7 to rotate, thereby adjusting the height of the movable seat 23, which can improve the height adjustment efficiency and save manpower.

[0056] By setting a fixing component in the height adjustment structure 7, the rotation of the lead screw 71 due to accidental contact can be avoided, thereby improving the stability of the lead screw 71 in the stopped rotation state, and consequently improving the stability of the moving seat 23 in maintaining the current height.

[0057] Furthermore, when the fasteners are bolts with hexagonal heads, in steps S1 and S3, there is no need for the worker to manually tighten the operating lever 741. The worker can simply place the hexagonal socket of the electric wrench onto the hexagonal head of the bolt and use the electric wrench to tighten the bolt. This is more labor-saving compared to manually tightening the operating lever 741 at the end of the screw 74.

[0058] See Figure 12 The protective net structure 3 includes an upper support rope 31, a lower support rope 32, a longitudinal support rope 33, and a net body 34. The upper support rope 31, the lower support rope 32, and the longitudinal support rope 33 are all made of steel wire rope, and the net body 34 can be made of steel wire rope net.

[0059] See Figure 12 The upper support rope 31 is used to connect the upper ends of the connecting columns 21 of two adjacent steel columns 2. See also Figure 9 Both ends of the upper support rope 31 are provided with upper rope loops 311. The upper rope loops 311 are fitted onto the connecting post 21. The limiting plate 22 on the connecting post 21 is used to prevent the upper rope loops 311 from detaching from the connecting post 21, which can improve the reliability of the upper rope loops 311 being fitted onto the connecting post 21.

[0060] See Figure 12 The lower support rope 32 is used to connect the movable seats 23 at the lower ends of two adjacent steel columns 2. See also Figure 10 Both ends of the lower support rope 32 are provided with lower rope loops 321. The lower rope loops 321 are fitted onto the movable seat 23. The limiting plate 22 on the movable seat 23 is used to prevent the lower rope loops 321 from detaching from the movable seat 23, which can improve the reliability of the lower rope loops 321 being fitted onto the movable seat 23.

[0061] See Figure 9 and Figure 10 The longitudinal support rope 33 has longitudinal rope loops 331 at both its upper and lower ends. The upper longitudinal rope loop 331 of the longitudinal support rope 33 is fitted onto the connecting post 21, and the lower longitudinal rope loop 331 of the longitudinal support rope 33 is fitted onto the movable seat 23. The limiting plate 22 on the connecting post 21 can prevent the upper longitudinal rope loop 331 of the longitudinal support rope 33 from detaching from the connecting post 21, thereby improving the reliability of the upper longitudinal rope loop 331 of the longitudinal support rope 33 being fitted onto the connecting post 21. The limiting plate 22 on the movable seat 23 is used to prevent the lower longitudinal rope loop 331 of the longitudinal support rope 33 from detaching from the movable seat 23, thereby improving the reliability of the lower longitudinal rope loop 331 of the longitudinal support rope 33 being fitted onto the movable seat 23.

[0062] See Figure 12The mesh openings at the upper end of the net body 34 are fitted onto the upper support rope 31, the mesh openings at the lower end of the net body 34 are fitted onto the lower support rope 32, and the mesh openings on the side of the net body 34 are fitted onto the longitudinal support rope 33.

[0063] The process of assembling protective net structure 3 is as follows:

[0064] S1. Pass the upper support rope 31 through the mesh at the upper end of the net body 34, pass the lower support rope 32 through the mesh at the lower end of the net body 34, and pass the longitudinal support rope 33 through the mesh on the side of the net body 34.

[0065] S2. After passing the end of the upper support rope 31 around the connecting post 21, secure it with a rope buckle 35 to obtain an upper rope loop 311 fitted on the connecting post 21; after passing the upper end of the longitudinal support rope 33 around the connecting post 21, secure it with a rope buckle 35 to obtain a longitudinal rope loop 331 fitted on the connecting post 21; after passing the lower end of the longitudinal support rope 33 around the movable seat 23, secure it with a rope buckle 35 to obtain a longitudinal rope loop 331 fitted on the movable seat 23; after passing the end of the lower support rope 32 around the movable seat 23, secure it with a rope buckle 35 to obtain a lower rope loop 321 fitted on the movable seat 23.

[0066] Through the above steps S1 and S2, the assembly of the protective net structure 3 can be completed. In the above protective net structure 3 of this embodiment, the periphery of the net body 34 can be supported by the upper support rope 31, the lower support rope 32 and the longitudinal support rope 33, which can improve the strength of the periphery of the net body 34.

[0067] In addition, in slope protection devices, see Figure 10 A base 24 is provided below the steel column 2, and through holes 241 are provided around the perimeter of the base 24. (See also...) Figure 11 After the through hole 241 is penetrated by the anchor bolt 111 embedded in the concrete seat 11, the anchor nut 112 is screwed onto the anchor bolt 111, so that the periphery of the base 24 is pressed against the top surface of the concrete seat 11 by the anchor nut 112, thereby installing the base 24 in the concrete seat 11 below the slope 1.

[0068] The slope protection device also includes anchor ropes 4 and anchor bolts 5. See also Figure 9 The upper end of the anchor rope 4 is provided with an anchor rope loop 41, which is fitted onto the connecting column 21. In addition, the lower end of the anchor rope 4 is connected to the anchor rod 5, which is fixed to the slope 1 by cast-in-place concrete.

[0069] See Figure 11 When assembling the steel column 2 and the base 24, the anchor rope 4 pulls the steel column 2 to rotate to the specified angle. The locking bolt 242 is then inserted through the bottom of the base 24 and the steel column 2. Finally, the locking nut 243 is screwed onto the locking bolt 242. (See below.) Figure 6 and Figure 7 This allows the hexagonal heads of the locking nut 243 and the locking bolt 242 to clamp the bottom of the base 24 and the steel column 2, thereby locking the steel column 2 onto the base 24 and installing the steel column 2 on the slope 1.

[0070] The working principle of a slope protection device in this embodiment is as follows:

[0071] When a loose rock 6 rolls down to the bottom of slope 1, the rock 6 will be blocked by the net body 34. Because the space on the side of the net body 34 facing slope 1 is limited, it is difficult to accommodate cleaning equipment (such as excavators and forklifts) to enter, making it inconvenient to remove the rock 6 from the side of the net body 34 facing slope 1.

[0072] In this embodiment, firstly, the height adjustment structure 7 is used to raise the movable seat 23. The movable seat 23 drives the lower support rope 32 to move upward, and the lower support rope 32 drives the lower end of the net body 34 to move upward, gradually exposing the rock 6 that was originally blocked by the net body 34. The net body 34 has more space on the side away from the slope 1, and the workers drive the cleaning equipment to clean away the rock 6 from the side of the net body 34 away from the slope 1. Finally, the height adjustment structure 7 is used to lower the movable seat 23. The movable seat 23 drives the lower support rope 32 to move downward, and the lower support rope 32 drives the lower end of the net body 34 to move downward and reset.

[0073] Because each steel column 2 is equipped with two movable seats 23 and two height adjustment structures 7 at its lower end, and each height adjustment structure 7 adjusts one movable seat 23, the lower end of the net body 34 between two adjacent steel columns 2 can be raised independently, while the adjacent net bodies 34 can remain in their original state, so as to maintain the protective function of the adjacent net bodies 34.

[0074] When clearing the rock 6 blocked by the net body 34, it is only necessary to raise the height of the lower end of the net body 34. After the height of the lower end of the net body 34 blocking the rock 6 is raised, the rock 6 can be exposed from the side of the net body 34 away from the slope 1, which makes it convenient for workers to drive the clearing equipment to clear the rock 6 from the side of the net body 34 away from the slope 1, thus making it convenient to clear the rock 6.

[0075] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
