Technical Field
[0001] This utility model relates to the field of slope protection technology, and in particular to a composite material support column structure for slope protection. Background Technology
[0002] Slope protection is an important measure to ensure safe production and the stability of the surrounding environment in engineering projects such as highways, railways, mining, and construction. To prevent risks such as rockfalls and rockfalls on slopes, temporary or semi-permanent protective devices are usually installed along the edge of the slope or in areas with potential risks.
[0003] Currently, widely used slope protection devices mainly fall into two categories: rigid guardrails and flexible protective nets. Rigid guardrails are typically composed of metal posts and crossbars, with a robust structure capable of effectively resisting impacts of considerable energy. However, they have poor permeability, limiting their ability to protect against small rocks or soil slippage, and are relatively expensive. Flexible protective nets, on the other hand, can cover a larger area and effectively intercept small falling rocks and debris, but their overall structural strength and impact resistance are not as good as rigid guardrails.
[0004] In practical engineering applications, the protection requirements for different slope sections or different stages of the same project are dynamically changing. For example, some areas require sturdy guardrails to prevent accidental falls of vehicles or large equipment, while other areas only need to be covered with protective netting to prevent sporadic rockfalls. Existing protective devices are typically limited in function and cannot be switched between guardrails and protective netting. This forces construction companies to procure, transport, and install various types of protective equipment according to different needs, increasing project costs and management complexity, and reducing construction flexibility and efficiency.
[0005] Furthermore, for flexible protective netting that requires temporary deployment, the installation and dismantling process often relies heavily on manual labor, especially during recycling and storage. The netting needs to be manually disassembled, rolled up, and transported elsewhere. This process is not only inefficient, but the recycled netting is also easily exposed to environmental factors such as sunlight and rain, accelerating material aging, shortening its lifespan, and creating safety hazards for future use.
[0006] Therefore, this utility model proposes a composite material support column structure for slope protection to overcome the shortcomings of the prior art. Utility Model Content
[0007] In view of the problems of existing slope protection devices, such as limited functionality, inability to adapt to changing site requirements, cumbersome recycling operations, and susceptibility to damage, this utility model aims to provide a composite material support column structure for slope protection with an improved structure that can effectively solve the above problems.
[0008] This utility model provides a composite material support column structure for slope protection, including: a base, and a protection mechanism and a recycling mechanism disposed on the base.
[0009] The protective mechanism includes at least two protective posts, a take-up roller, a protective net, fixing strips, a limiting component, and multiple protective rods. The protective posts are hollow inside, with openings on their outer walls for the protective net and fixing strips to pass through. The take-up roller is rotatably mounted inside the protective post, on which the protective net is wound, with fixing strips fixedly connected to the ends of the net. The limiting component is located on the outer wall of the protective post, and has elongated limiting grooves and threaded grooves. One end of each protective rod is fixedly connected to a threaded post.
[0010] The recovery mechanism is located at the bottom of the protective column, near the base. The recovery mechanism includes a rotating disk, a limiting claw, a spring, and a pressing plate.
[0011] In this design, the threaded post of the protective rod and the threaded groove on the protective post are connected by a threaded rotational connection, and the other end of the protective rod is fixed to the side wall groove of the protective post by an insertion connection. Simultaneously, the rotating disk within the recovery mechanism is driven by the take-up roller; the bottom of the limiting claw is elastically connected by a spring, and a pressing plate is connected to its side; the spring is positioned below the limiting claw and pushes it upward, causing it to engage with the bottom groove of the rotating disk; the pressing plate is driven by the limiting claw and is used to move the limiting claw downward under pressure to disengage it from the bottom groove of the rotating disk.
[0012] Preferably, to improve the fixing reliability of the mesh protection, the structure of the fixing strip and its matching elongated limiting groove are further defined. The width of the fixing strip is designed to be greater than the opening width of the elongated limiting groove, and locking blocks for engaging inside the elongated limiting groove are integrally formed on both sides. This structure ensures that the fixing strip can be firmly locked after being inserted, preventing accidental dislodgement under external force.
[0013] Preferably, to simplify the installation of the guardrail and ensure its stability, the plug-in fixing structure of the guardrail rod and the guardrail post is specified. A positioning hole is provided in the groove on the side wall of the guardrail post, and a corresponding positioning pin is provided at the other end of the guardrail rod to mate with the positioning hole. Through the precise fit of the pin hole, quick alignment and a secure connection are achieved.
[0014] Preferably, to achieve flexible expansion of the guardrail length, the guardrail rods can not only connect to guard posts but also connect to each other. At the other end of the guardrail rod, near the positioning pin, a threaded groove is provided. The specifications of this threaded groove are the same as those of the threaded post, allowing multiple guardrail rods to be connected in series by the sequential threaded rotation of the threaded post and the threaded groove to form a continuous guardrail of any desired length.
[0015] Preferably, the spring providing the restoring force in the retrieval mechanism is a compression spring. One end of this compression spring is connected to the bottom of the limiting claw, and the other end is connected to the bottom of the housing of the retrieval mechanism. This arrangement provides the limiting claw with a stable and direct upward pushing force, ensuring the immediacy and reliability of the locking function.
[0016] Preferably, to ensure efficient transmission of the winding action, the transmission connection between the winding roller and the rotating disk is achieved through a gear transmission mechanism or a chain transmission mechanism located between them. Both of these transmission methods feature accurate transmission ratios and reliable operation, ensuring that the winding roller can rotate synchronously and smoothly when the rotating disk is operated.
[0017] Preferably, to achieve reliable multi-point locking of the rotating disk, the bottom surface of the rotating disk is evenly distributed with multiple bottom grooves along its circumference. Correspondingly, the end of the limiting claw is shaped into a claw tip that matches the bottom groove. Under the push of the spring, this claw tip can precisely engage with any one of the bottom grooves, thus achieving a secure lock at any rewinding position.
[0018] Preferably, to enhance the structural strength of the restraining component and simplify the manufacturing process, the restraining component is designed as a protrusion integrally formed on the outer wall of the protective post. The elongated restraining groove for fixing the protective net and the threaded groove for connecting the protective rod are both formed on the same side surface of this integral protrusion. This integrated design not only makes the structure more compact, but also improves the overall load-bearing capacity and durability.
[0019] This utility model has the following beneficial effects: 1. This utility model solves the problem that existing slope protection devices are single-function and cannot adapt to changing site requirements by integrating a retractable protective net inside the support column and setting a threaded groove on its outer wall for connecting the protective rod. It achieves the technical effect of combining the functions of mesh isolation and guardrail protection, and significantly improving the applicability and flexibility of the device.
[0020] 2. This utility model, by setting up a recycling mechanism consisting of a rotating disk, limiting claws, springs and pressing plates, stores the protective net inside the protective column, solving the problems of cumbersome, time-consuming and labor-intensive recycling operations of traditional protective nets, and their susceptibility to environmental erosion and damage due to long-term exposure to the outside. It achieves the technical effect of convenient, time-saving and labor-saving recycling of protective nets, and effectively extending their service life.
[0021] 3. This utility model solves the problems of complex installation process and insufficient connection reliability of some protective devices by using a fixed strip and a long strip limiting groove to fix the protective net and a threaded column and a threaded groove to rotate and connect the protective rod. It achieves the technical effect that both protective modes can be quickly deployed and the connection is stable and reliable. Attached Figure Description

[0024] Example: Reference Figures 1 to 4 This utility model provides a composite material support column structure for slope protection, which aims to solve the problems of limited functionality and inconvenient recycling of existing slope protection devices.
[0025] like Figure 1 and Figure 2 As shown, the composite material support column structure for slope protection includes a base 1, and a protection mechanism 2 and a recovery mechanism 3 mounted on the base 1. The base 1 serves as the mounting base for the entire device, providing stable support. The protection mechanism 2 and the recovery mechanism 3 are fixedly connected and mounted on top of the base 1.
[0026] The protective mechanism 2 includes at least two protective posts 21. The interior of each protective post 21 is hollow to accommodate other components. An opening is provided on the outer wall of each protective post 21 for the protective net 23 and fixing strips 24 to pass through, providing a passage for the unfolding and retraction of the protective net 23. A take-up roller 22 is rotatably mounted inside each protective post 21. The protective net 23 is wound around the take-up roller 22, and the end of the protective net 23 is fixedly connected to the fixing strip 24.
[0027] The protective mechanism 2 also includes at least one limiting component 25, which is disposed on the outer wall of the protective post 21. The limiting component 25 has an elongated limiting groove 251 and a threaded groove 252. The elongated limiting groove 251 is used to engage the fixing strip 24 of the protective net 23. When the protective net 23 is pulled out and unfolded, the fixing strip 24 can be easily fixed in the elongated limiting groove 251, achieving mesh protection. The threaded groove 252 is used for threaded connection with the threaded post 27 on the protective rod 26. The limiting component 25 is an integral protrusion disposed on the outer wall of the protective post 21. Both the elongated limiting groove 251 and the threaded groove 252 are formed on the same side surface of the limiting component 25. This integral design enhances the integrity and stability of the structure.
[0028] The protective mechanism 2 also includes multiple protective rods 26. One end of each protective rod 26 is fixedly connected to a threaded post 27, which is threadedly rotatably connected to a threaded groove 252 on the protective post 21. The other end of the protective rod 26 is inserted and fixed into a groove on the side wall of the protective post 21. More specifically, a positioning hole is provided in the groove on the side wall of the protective post 21, and a positioning pin is provided at the other end of the protective rod 26 to mate with the positioning hole for insertion and fixation. This design makes the installation and removal of the protective rod 26 more convenient and secure. At the other end of the protective rod 26, near the positioning pin, a threaded groove 252 is also provided. This threaded groove 252 is used for threaded rotatable connection with the threaded post 27 of another protective rod 26, allowing multiple protective rods 26 to be connected together to form an adjustable-length guardrail-style protection.
[0029] The recycling mechanism 3 is located at the bottom of the protective post 21, near the base 1. The recycling mechanism 3 includes a rotating disk 31, a limiting claw 32, a spring 33, and a pressing plate 34. The rotating disk 31 is connected to the winding roller 22 via a transmission connection; the rotation of the rotating disk 31 directly drives the winding roller 22 to rotate, thereby achieving the winding of the protective net 23. The spring 33 in the recycling mechanism 3 is a compression spring, located below the limiting claw 32. One end of the spring 33 is connected to the bottom of the limiting claw 32, and the other end is connected to the bottom of the housing of the recycling mechanism 3. The spring 33 pushes the limiting claw 32 upwards through its elastic force.
[0030] A spring 33 is elastically connected to the bottom of the limiting claw 32. Under normal conditions, the spring 33 pushes the limiting claw 32 upwards, engaging it in the bottom groove of the rotating disk 31 to restrict its rotation and prevent the protective net 23 from accidentally unfolding. A pressing plate 34 is connected to the side of the limiting claw 32, and the pressing plate 34 is kinetically connected to the limiting claw 32. When the pressing plate 34 is pressed, it causes the limiting claw 32 to move downwards, disengaging it from the bottom groove of the rotating disk 31, allowing the rotating disk 31 to rotate freely. The bottom surface of the rotating disk 31 has multiple bottom grooves evenly distributed circumferentially. The limiting claw 32 has claw tips that fit into these grooves, and the spring 33 pushes the claw tips into one of the bottom grooves.
[0031] The width of the fixing strip 24 of the protective net 23 is greater than the width of the slot of the long strip limiting groove 251, and the two sides of the fixing strip 24 are provided with locking blocks for engaging inside the long strip limiting groove 251. This ensures that the fixing strip 24 can be securely locked after being engaged in the long strip limiting groove 251 and will not easily fall off. The winding roller 22 and the rotating disk 31 are connected by a gear transmission mechanism or chain transmission mechanism between them, ensuring reliable power transmission between them.
[0032] Reference Figure 1 , Figure 3 and Figure 4 The recycling mechanism 3 is located at the bottom of the protective column 21. Inside it is a rotating disk 31 that can rotate around the central axis. The rotating disk 31 is connected to the winding roller 22 inside the protective column 21 through a gear transmission mechanism or a chain transmission mechanism. The bottom surface of the rotating disk 31 is provided with multiple bottom grooves evenly distributed along its circumference.
[0033] The recycling mechanism 3 also includes a limiting claw 32 that can move vertically up and down, the limiting claw 32 having claw tips that fit into the bottom groove. The bottom of the limiting claw 32 is elastically connected to a spring 33, which acts as a compression spring and always provides an upward thrust to the limiting claw 32. A pressing plate 34, which is drivenly connected to the limiting claw 32, extends from the side wall of the recycling mechanism 3.
[0034] In the assembled state, the elastic force of spring 33 pushes the limiting claw 32 to the upper position, with its claw tip engaging any bottom groove on the bottom surface of the rotating disk 31, thereby circumferentially limiting the rotating disk 31 and preventing its rotation. When it is necessary to wind up the protective net 23, pressure is applied to the externally exposed pressing plate 34. The pressing plate 34 drives the limiting claw 32 to move downward synchronously against the elastic force of spring 33 until the claw tip of the limiting claw 32 completely disengages from the bottom groove of the rotating disk 31. At this time, the rotation restriction of the rotating disk 31 is released, and the operator can drive the winding roller 22 to rotate synchronously to wind up the protective net 23 by rotating the rotating disk 31. After winding is completed, the pressure applied to the pressing plate 34 is released, the elastic potential energy stored in spring 33 is released, pushing the limiting claw 32 to reset upward, and its claw tip re-engages in the nearest bottom groove, locking the rotating disk 31 again.
[0035] As a preferred embodiment, in order to ensure the reliability of the fixed net 23 after it is unfolded, the cooperation structure between the fixing strip 24 and the long strip limiting groove 251 is specifically defined. The overall width of the fixing strip 24 is greater than the width of the groove of the long strip limiting groove 251, and a locking block is integrally formed on both sides of the fixing strip 24. The size of the locking block is designed to be able to pass through the groove of the long strip limiting groove 251 and be locked inside the groove.
[0036] As another preferred embodiment, to achieve stable installation and flexible expansion of the guardrail protection, the connection structure of the guardrail 26 is further refined. At the connection end between the guardrail 26 and the guard post 21, a positioning hole is provided in the side wall groove of the guard post 21, and a positioning pin is provided at the other end of the guardrail 26 that can be inserted into the positioning hole. The positioning pin and the positioning hole are engaged to achieve the insertion and fixation. At the same time, in order to connect multiple guardrails 26, a threaded groove 252 is also provided at the other end of the guardrail 26, that is, near the positioning pin. The specification of this threaded groove 252 matches the threaded post 27, so that the threaded post 27 of one guardrail 26 is screwed into the threaded groove 252 of the adjacent guardrail 26.
[0037] As another preferred embodiment, in order to improve the stability and reliability of the operation of the recycling mechanism 3, its internal locking and reset structure is further defined. The spring 33 is specifically a compression spring, one end of which abuts against the bottom of the limiting claw 32, and the other end abuts against the bottom surface of the inner shell of the recycling mechanism 3. In cooperation with this, the bottom surface of the rotating disk 31 is provided with a plurality of bottom grooves evenly distributed along its circumference. The lower end of the limiting claw 32 is formed into a claw tip that matches the shape of the bottom groove. In the locked state, the elastic force of the compression spring pushes the claw tip of the limiting claw 32 to accurately embed into one of the bottom grooves.
[0038] As a preferred embodiment, to ensure the effective transmission of the winding action, the transmission connection between the winding roller 22 and the rotating disk 31 is specifically achieved through a gear transmission mechanism disposed between the two, or through a chain transmission mechanism.
[0039] As a preferred embodiment, to enhance the structural strength and ease of installation of the limiting component 25, the limiting component 25 is designed as a protrusion structure integrally formed with the protective post 21, and the elongated limiting groove 251 and the threaded groove 252 are both formed on the same side surface of this integral protrusion.
[0040] The working principle is as follows: When a mesh protection is required, the operator pulls the fixing strip 24 inside the protection mechanism 2, so that the protective net 23 connected to the fixing strip 24 is pulled out from the opening of the protective post 21, and drives the take-up roller 22 to rotate until the protective net 23 is stretched to the predetermined position. Then, the fixing strip 24 is placed in the long strip limiting groove 251 of the limiting component 25 on another protective post 21. The locking is achieved by the cooperation of the locking blocks on both sides of the fixing strip 24 with the inside of the groove, forming a mesh protection structure.
[0041] When deploying guardrail protection, hold the guardrail 26 and align the threaded post 27 at one end with the threaded groove 252 of the limiting component 25 on the guardrail 21. Rotate the guardrail 26 to make the threaded post 27 and the threaded groove 252 threadedly connected. If the guardrail needs to be extended, take another guardrail 26 and connect its threaded post 27 to the threaded groove 252 at the other end of the installed guardrail 26. Repeat this process until the required length is reached. Finally, align the positioning pin at the other end of the end guardrail 26 and insert it into the positioning hole in the groove on the side wall of the target guardrail 21 to complete the construction of the guardrail protection.
[0042] When disassembling or retrieving the protective net 23, press the pressing plate 34 of the retrieval mechanism 3. The pressing plate 34 drives the limiting claw 32 to move downward and squeeze the spring 33 at its bottom. The claw tip of the limiting claw 32 then disengages from the groove at the bottom of the rotating disk 31, releasing the rotation restriction on the rotating disk 31. At this time, the operator rotates the rotating disk 31, which drives the winding roller 22 to rotate synchronously through the transmission mechanism, quickly winding the external protective net 23 into the interior of the protective column 21. After winding is completed, the pressure applied to the pressing plate 34 is released. The reaction force of the spring 33 causes the limiting claw 32 to automatically reset upward, and its claw tip re-engages in the groove at the bottom of the rotating disk 31, locking the rotating disk 31 and preventing the protective net 23 from loosening.
