Description

Technical Field

[0001] This utility model relates to the technical field of slope protection net production equipment, and more specifically, to a portable installation mechanism for a passive slope protection net fixing buckle. Background Technology

[0002] Passive slope protection netting is an engineering facility used for slope protection to prevent damage to human life and property caused by geological disasters such as landslides and debris flows. It mainly consists of wire rope netting, ring netting, a fixing system, pressure-reducing rings, and steel columns. Through the synergistic action of these components, passive slope protection netting forms a unified protective structure, effectively passively intercepting and blocking rocks and soil rolling down the slope, thereby protecting below-mountain railways, highways, buildings, and other facilities from damage.

[0003] The surface of a passive slope protection net is generally made up of several interlocking ring-shaped steel cables. Each ring-shaped steel cable is formed by twisting several steel wires together to increase strength. The twisted steel cables are generally tied and fixed with fasteners.

[0004] In the production process of passive slope protection nets, due to the fact that several interlocking ring nets are connected together, it is difficult to quickly install the fixing buckles on the entire ring net. Generally, two workers are required, one to hold the ring net in place and the other to hydraulically install the fixing buckles. This operation is relatively troublesome and inefficient, making it difficult to quickly and completely install the fixing buckles on the entire passive protection net surface. Utility Model Content

[0005] The purpose of this application is to provide a portable installation mechanism for fixing buckles on passive slope protection nets, which solves the technical problem of automatically fixing and installing fixing buckles on multiple ring nets.

[0006] To solve the above-mentioned technical problems, the solution adopted in this application is as follows:

[0007] A portable installation mechanism for a passive slope protection net fixing buckle includes a support counter, on which a fixing column is arranged horizontally, and a buckle assembly is arranged on the fixing column. A fixing buckle is arranged in the buckle assembly, and the opening of the fixing buckle faces upward.

[0008] Preferably, a snap fastener is provided directly above the buckle assembly, and an expansion assembly is provided directly below the buckle assembly.

[0009] Preferably, the outer ends of the buckle assembly and the expansion assembly respectively abut against the inner two ends of the ring mesh, the expansion assembly is mounted on the displacement assembly, the displacement assembly is fixed on the support counter, and the displacement direction of the expansion assembly is vertical.

[0011] Preferably, the expansion component is connected to the rotating end of the rotating component, and when the rotating end of the rotating component rotates, the expansion component rolls against the ring mesh.

[0012] Preferably, the snap fastener assembly is mounted on the displacement assembly, and the snap fastener assembly is displaced vertically by the displacement assembly.

[0013] Preferably, a plurality of buckle assemblies are evenly arranged along the axial direction on the fixed column.

[0014] Preferably, the number of buckle components corresponds one-to-one with the number of snap-fit ​​components and expansion components.

[0015] Preferably, the buckle assembly includes an annular plate with a magnetic ring rotatably disposed on the annular plate. An arc-shaped cavity is fitted onto the outer side of the annular plate, through which the magnetic ring passes. Multiple fixing buckles are placed inside the arc-shaped cavity, with the bottom of the fixing buckles magnetically abutting against the outer ring surface of the magnetic ring.

[0016] Preferably, the top of the arc-shaped chamber near the snap fastener assembly is provided with a snap-fit ​​opening, and the shadow area projected by the snap-fit ​​opening is greater than the maximum area of ​​the snap fastener.

[0017] Preferably, an elastic component is provided inside the arc-shaped cavity at the other end away from the buckle assembly. One end of the elastic component is connected to the inside of the arc-shaped cavity, and the other end abuts against the last of the multiple buckles.

[0018] Preferably, a proximity sensor is provided on one side of the arc-shaped chamber near the snap fastener assembly, and the sensing end of the proximity sensor corresponds to the position of the fixing buckle under the snap fastener opening.

[0019] Preferably, the end of the arc-shaped chamber near the snap fastener assembly is provided with a slot, and the width of the slot is greater than the wire diameter of the annular mesh.

[0021] Preferably, after the fixing buckle is pressed into the ring mesh, the opening on one side of the fixing buckle is closed, and the groove width is greater than the maximum diameter of the fixing buckle.

[0022] Preferably, the expansion component includes an annular groove plate, and a plurality of rubber strips are disposed in the annular groove of the annular groove plate, the plurality of rubber strips being evenly arranged circumferentially in the annular groove.

[0026] In this utility model, by setting an expansion component that can be vertically displaced directly below the buckle assembly, the ring mesh is placed on the buckle assembly and the expansion component. The displacement of the expansion component increases the spacing between them, thus fixing the ring mesh and ensuring the precise pressing of the buckle assembly.

[0027] In this invention, by using a rotating component to drive the expansion component to rotate, after the fixing buckle is installed on the ring mesh, it can be rotated to drive the fixing buckle to disengage from the buckle assembly, and the fixing buckle can continue to be installed at a new end of the ring mesh. Meanwhile, an elastic component is set inside the buckle assembly to ensure that after the previous fixing buckle is installed and removed, the next fixing buckle can be pressed into the pressing position by the elastic force for new pressing and fixing.

[0038] Example

[0039] Please refer to Figures 1-7 This utility model provides a portable installation mechanism for a passive slope protection net fixing buckle, including a support cabinet 1, a fixing column 2, a buckle assembly 3, a fixing buckle 4, an expansion assembly 5, a ring net 6, a displacement assembly 7, a rotation assembly 8, and a snap fastener assembly 9.

[0040] Furthermore, the support counter 1 is placed on the ground to provide support and ensure balance. A fixing post 2 is horizontally fixed on the mounting surface of the support counter 1. A buckle assembly 3 is fixedly installed on the fixing post 2. The buckle assembly 3 is provided with multiple fixing buckles 4 for storing the fixing buckles 4 and restricting the position of the fixing buckles 4 so that the opening of the fixing buckles 4 faces upward. The top of the ring net 6 is also placed on the buckle assembly 3 and fitted into the fixing buckles 4. A pressure buckle assembly 9 is provided directly above the buckle assembly 3 to fix the fixing buckles 4 to the ring net 6.

[0041] The snap fastener assembly 9 includes a hydraulic cylinder 901 and a pressing assembly. The hydraulic cylinder 901 is connected to the pressing assembly, and the pressing assembly is vertically aligned with the fixed buckle 4. When the pressing assembly is vertically pressed by the hydraulic cylinder 901, the pressing assembly squeezes the opening of the fixed buckle 4 to close it, so that the fixed buckle 4 is sleeved and fixed on the outside of the ring net 6.

[0042] Preferably, the entire installation of the fixing buckle 4 only requires one worker to place the ring net 6 on the buckle assembly 3, and the fixing buckle 4 can be automatically installed by the buckle assembly 9.

[0043] Furthermore, an expansion component 5 is provided directly below the buckle assembly 3. The outer ends of the buckle assembly 3 and the expansion component 5 respectively abut against the inner ends of the ring mesh 6. The expansion component 5 is mounted on the displacement component 7, which is fixed to the support counter 1.

[0044] Preferably, when the worker places the ring net 6 onto the buckle assembly 3, the expansion assembly 5 moves vertically upward toward the buckle assembly 3 via the displacement assembly 7, reducing the gap between the two, so that the worker can quickly put the ring net 6 onto the buckle assembly 3 and the expansion assembly 5; after the ring net 6 is placed, when the fixing buckle 4 is pressed in, the expansion assembly 5 moves vertically downward away from the buckle assembly 3 via the displacement assembly 7, increasing the gap between the two, until the gap is consistent with the diameter of the ring net 6, at which point the expansion assembly 5 and the buckle assembly 3 together open and fix the ring net 6, preventing it from rotating at will and affecting the pressing of the fixing buckle 4.

[0045] In addition, the expansion component 5 is also fixedly connected to the rotating end of the rotating component 8. When the rotating component 8 drives the expansion component 5 to rotate, the expansion component 5 rolls against the ring mesh 6, thereby using frictional resistance to drive the ring mesh 6 to rotate, so that one end of the ring mesh 6 that has been pressed with the fixing buckle 4 rotates away from the pressing position, and the other end of the ring mesh 6 rotates to the pressing position for pressing with the fixing buckle 4.

[0046] Furthermore, the snap fastening assembly 9 is also installed on the corresponding displacement assembly 7. The displacement assembly 7 is fixed on the support counter 1. The snap fastening assembly 9 is vertically displaced through the displacement assembly 7, which makes it easy for the snap fastening assembly 9 to quickly move away from the buckle assembly 3 when the ring net 6 is manually placed or when the buckle assembly 3 fails, so as to facilitate the installation of the ring net 6 or the maintenance of the device.

[0047] Furthermore, a number of buckle components 3 are evenly arranged along the axial direction on the fixed column 2; the number of buckle components 3 corresponds one-to-one with the number of snap fasteners 9 and expansion components 5.

[0048] Preferably, since the passive slope protection net is composed of several interlocking ring nets 6, and each ring net 6 is equipped with multiple fixing buckles 4, multiple components are set up to perform synchronous pressing of the ring nets 6 in order to install the fixing buckles 4 on multiple interlocking ring nets 6 at the same time.

[0049] Please refer to Figures 2-4 In this embodiment, the snap fastening assembly 9 and the expansion assembly 5 are both connected to the displacement assembly 7. The displacement assembly 7 includes a sliding rod 701, an electric cylinder 702, a balance plate 703, and a sliding groove 704.

[0050] Specifically, a sliding groove is provided on the mounting surface of the installation counter, and a sliding rod 701 is slidably installed in the sliding groove. The sliding rod 701 is horizontally inserted through the installation counter. A snap fastener assembly 9 and an expansion assembly 5 are respectively provided on the sliding rod 701. A cavity is provided inside the installation counter. One end of the sliding rod 701 inserted through the cavity is fixedly connected to the middle of the balance plate 703. One end of the balance plate 703 is fixedly connected to the drive end of the electric cylinder 702. The electric cylinder 702 is fixed inside the cavity. The other end of the balance plate 703 is slidably installed in a sliding groove 704, which is set on the inner wall of the cavity.

[0051] The system includes a balance plate 703 and a sliding groove 704 to ensure that the two ends of the balance plate 703 move synchronously, thereby driving the snap fastener assembly 9 and the expansion assembly 5 to move smoothly without tilting.

[0052] Please refer to Figures 5-7 In this embodiment, the buckle assembly 3 includes an annular plate 301, an arc-shaped cavity plate 302, a magnetic ring 303, a proximity sensor 305, a press-fit opening 306, and an elastic component.

[0053] Specifically, an arc-shaped cavity is fixedly sleeved on the outer side of the annular plate 301. The arc-shaped cavity is composed of an arc-shaped cavity plate 302. A cavity is provided inside the arc-shaped cavity plate 302 for placing multiple fixing buckles 4. An annular opening is provided on the outermost side of the arc-shaped cavity plate 302 so that the annular mesh 6 sleeved on the outside can enter the arc-shaped cavity and be sleeved with the fixing buckles 4.

[0054] A press-fit opening 306 is provided at the top of one end of the arc-shaped cavity plate 302 near the press-fit assembly 9. The press-fit opening 306 penetrates the interior of the arc-shaped cavity. The shadow area projected by the press-fit opening 306 is greater than the maximum area of ​​the fixing buckle 4, exposing the internal fixing buckle 4 to the outside.

[0055] Meanwhile, an elastic component is provided inside the arc-shaped cavity at the other end away from the snap fastener assembly 9. The elastic component includes a spring 307 and a pressure plate 308. One end of the spring 307 is fixedly connected to the inside of the arc-shaped cavity, and the other end is fixedly connected to the pressure plate 308. The pressure plate 308 abuts against the last snap fastener 4 among the multiple snap fasteners 4 placed in the arc-shaped cavity, applying elastic force to the snap fastener 4 in the arc-shaped cavity, pressing the snap fastener 4 to the pressing position opening 306 at the other end of the arc-shaped cavity, so that the snap fastener assembly 9 above can press it in place.

[0056] The ends of the arc-shaped chamber near the snap fastener 9 are also provided with slots. The width of the slots is greater than the wire diameter of the ring mesh 6, so that the ring mesh 6 can rotate directly in the arc-shaped chamber when the expansion assembly 5 rotates.

[0057] When the fixing buckle 4 is not pressed onto the annular mesh 6, the opening on one side of the fixing buckle 4 is open, and the groove width is less than the maximum diameter of the fixing buckle 4, so that the fixing buckle 4, which is elastically squeezed, will not be pushed out from the groove. When the fixing buckle 4 is pressed onto the annular mesh 6, the opening on one side of the fixing buckle 4 is closed, the volume of the fixing buckle 4 becomes smaller, and the groove width is greater than the maximum diameter of the fixing buckle 4. At this time, the expansion component 5 drives the annular mesh 6 to rotate through the rotation component 8, and moves the pressed fixing buckle 4 out of the arc-shaped cavity. Then the elastic component will elastically squeeze the next fixing buckle 4 to the pressing position opening 306, which is convenient for the next pressing.

[0058] A proximity sensor 305 is also fixedly installed on one side of the arc-shaped chamber near the snap fastener assembly 9. The sensing end of the proximity sensor 305 corresponds to the position of the snap fastener 4 under the snap fastener opening 306 and corresponds to the opening position of the snap fastener 4.

[0059] When the retaining clip 4 is pushed to the press-fit opening 306, the proximity sensor 305 will sense and send a signal. The proximity sensor 305 is connected to the corresponding controller. The controller controls the different light switches of the external signal lights fixedly installed on the support counter 1 through the circuit. When the proximity sensor 305 sends a signal, the electrical signal will cause the controller to control the external signal lights to display a normal green light. If the retaining clip 4 is not detected, no signal will be sent. At this time, the controller does not receive an electrical signal and thus controls the external signal lights to display an alarm red light. When the retaining clip 4 is press-fitted, the opening of the retaining clip 4 is closed, and the position of the retaining clip 4 at the proximity sensor 305 changes. The proximity sensor 305 does not sense this and does not send a signal to the controller. At this time, the controller controls the external signal lights to display a normal green light. If the proximity sensor 305 senses the opening and sends a signal, the controller receives an electrical signal and controls the external signal lights to display an alarm red light.

[0060] In addition, a magnetic ring 303 is rotatably mounted on the annular plate 301. The magnetic ring 303 passes through the arc-shaped cavity. The bottoms of multiple fixing buckles 4 placed in the arc-shaped cavity are magnetically abutted against the outer ring surface of the magnetic ring 303. The outer ring surface of the magnetic ring 303 is arc-shaped and matches the shape of the fixing buckles 4. The magnetic ring 303 can rotate freely. When the elastic component pushes the fixing buckles 4 or the expansion component 5 to rotate and drive the annular mesh 6 to rotate, the magnetic ring 303 will be driven to rotate through the fixing buckles 4, thereby reducing the frictional resistance between the annular mesh 6 and the buckle assembly 3 and ensuring that the annular mesh 6 can rotate smoothly.

[0061] Please refer to Figure 2 and Figure 3 In this embodiment, the press-fitting component in the snap fastener assembly 9 includes a press post 902 and an arc-shaped groove 903.

[0062] Specifically, the pressure column 902 is fixed on the hydraulic rod of the hydraulic cylinder 901. The pressure column 902 corresponds vertically to the pressing position opening 306. The bottom end of the pressure column 902 is provided with an arc-shaped groove 903, and the opening of the arc-shaped groove 903 faces the pressing position opening 306 downward.

[0063] During press fitting, the hydraulic cylinder 901 drives the pressure column 902 to move downward. The bottom end of the pressure column 902 extends into the position of the fixing buckle 4 in the press fitting position opening 306. The groove surface of the arc-shaped groove 903 abuts against the snap-fit ​​of the fixing port. The snap-fit ​​is squeezed by the pressure column 902 and begins to close towards the center, thereby closing the opening of the fixing buckle 4 and fixing the fixing port onto the ring mesh 6.

[0064] All the switches of the hydraulic cylinders 901 are connected to the same controller. The controller can control all the hydraulic cylinders 901 to perform synchronous hydraulic pressure, ensuring the synchronous pressing of several fixed buckles.

[0065] In addition, the snap fastening assembly 9 also includes a laser sensor 904, which is fixed on the mounting surface of the support counter 1. The laser beam is directed along the axial direction of the fixed column 2 and is located in the gap between the snap fastening assembly and the snap fastening assembly 3.

[0066] When the worker manually places the ring net 6 onto the buckle assembly 3, the laser sensor 904 will detect it. The signal line of the laser sensor 904 is connected to the controller and will send a signal to the controller, causing the controller to stop the hydraulic cylinder 901 from working. Therefore, when the pressing work is being carried out, once an object appears on the pressing line between the pressing assembly and the buckle assembly 3, the laser sensor 904 will send a signal immediately, causing the controller to stop the hydraulic cylinder 901 from working, ensuring safety.

[0067] Please refer to Figure 7 In this embodiment, the expansion component 5 includes an annular groove plate 501, a baffle plate 502, and a rubber strip 503.

[0068] Specifically, the annular groove plate 501 is fixed on the sliding rod 701. The outer edge of the annular groove plate 501 is provided with an annular groove. Several rubber strips 503 are fixedly arranged in the annular groove. The rubber strips 503 are evenly arranged in the annular groove.

[0069] The sliding rod 701 connected to the annular groove is connected to the rotating component, which is a motor. The motor drive end is fixedly connected to the sliding rod 701 (the sliding rod 701 is rotatably set on the balance plate 703). When the annular groove plate 501 is driven to rotate by the motor, the rubber strip 503 at the bottom of the annular groove plate 501 will always abut against the inner side of the lower end of the annular mesh 6.

[0070] Preferably, because the rubber strip 503 is elastic and has a large surface frictional resistance, it can apply elastic force to the abutting annular mesh 6 and use the large frictional resistance to quickly drive the annular mesh 6 to rotate.

[0071] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description.
