Description

Technical Field

[0001] This utility model relates to the field of wire rack technology, specifically to an impact-resistant wire rack. Background Technology

[0002] As the name suggests, a utility pole is a pole used to carry power lines. They were found throughout rural areas, fields, roads, and streets, and were one of the important infrastructure projects in early China. Later, due to the development of steel and reinforced concrete, and technological requirements, these two materials replaced most wooden poles, and suitable timber gradually became scarce, making wooden poles virtually impossible to find in cities.

[0003] For example, Chinese utility model patent CN221895658U discloses a utility pole anti-collision device. Its technical solution includes a protective cylinder and a conical cover. The protective cylinder is located below the conical cover, and the protective cylinder and the conical cover are connected by bolts. The conical cover has a hollow internal structure. A utility pole is installed inside the protective cylinder. An annular groove is formed on the side wall of the utility pole above the conical cover. An inner cylinder is slidably connected to the side wall of the utility pole inside the conical cover. Multiple springs are fixedly connected. An outer cylinder is fixedly connected to the end of each spring furthest from the inner cylinder and located inside the conical cover. An outer ring is fixedly connected to the top of the inner cylinder. An annular stop is provided inside the outer ring. The utility pole is located inside the annular stop, which contacts the side wall of the utility pole. A small spring is fixedly connected to the inner wall of the outer ring, with its furthest end fixedly connected to the outer ring wall of the annular stop. A retaining ring is located below the inner cylinder and inside the protective cylinder, fixedly connected to the side wall of the utility pole. The inner cylinder and the retaining ring... A telescopic spring is installed in the middle of the ring. The two ends of the telescopic spring are fixedly connected to the bottom surface of the inner cylinder and the upper surface of the retaining ring, respectively. The utility pole is located inside the telescopic spring. A buffer cylinder is fixedly connected to the side wall of the utility pole below the retaining ring. An outer winch is installed between the buffer cylinder and the retaining ring. The outer winch is rotatably connected to the side wall of the utility pole. An elastic ring is installed on the outside of the outer winch and below the outer cylinder. Multiple brackets are fixedly connected to the side of the outer winch. The end of the bracket away from the outer winch is fixedly connected to the inner wall of the elastic ring. Multiple compression springs are installed between the protective cylinder and the buffer cylinder. The two ends of the compression springs are fixedly connected to the inner wall of the protective cylinder and the side of the buffer cylinder, respectively. A support column is fixedly connected to the inner wall of the protective cylinder and inside the multiple compression springs. Multiple fixing brackets are fixedly connected to the side wall of the utility pole and below the buffer cylinder. Multiple protective blocks are fixedly connected to the inner wall of the protective cylinder. Two connecting rods are fixedly connected to the side wall of the inner cylinder. The ends of the two connecting rods away from the inner cylinder are connected to a rectangular structure. The rectangular structure of the connecting rod contacts the bottom surface of the tooth structure of the outer winch.

[0004] The applicant's search revealed that there are still some problems in the above technical solutions that urgently need improvement. For example, in actual use, the protective barrel will deform due to impact, so it needs to be replaced. The connection between the protective barrel and one end of the spring makes the subsequent disassembly and assembly process more complicated. Therefore, we propose an anti-impact wire rack to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an impact-resistant cable tray with the advantage of easily replacing the impact-induced deformation buffer plate, thus solving the problem of cumbersome subsequent disassembly caused by one end of the protective plate being connected to the spring.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-collision cable rack, comprising a cable rack body and four buffer plates arranged in a ring, wherein a conical fixing block is fixed on the outer surface of the cable rack body, an mounting plate for fixing the cable rack body is fixed on the bottom surface of the cable rack body, a buffer assembly is fixed on the outer surface of the cable rack body, and each of the four buffer plates is provided with a disassembly assembly.

[0007] The buffer assembly includes four sets of two sleeves fixed to the outer surface of the wire frame body. A sleeve rod is sleeved inside the sleeve. A mounting plate is fixed to the other end of the sleeve rod. Four sets of two springs are fixed between the mounting plate and the wire frame body.

[0008] The buffer assembly also includes a connecting rod fixed inside the mounting plate, and a slider is fixed to the other end of the connecting rod.

[0009] Furthermore, the bottom surface of the fixing block is provided with four sliding grooves, and the four sliders are respectively located inside the four sliding grooves and slidably connected to them. The sliding grooves and sliders are all T-shaped.

[0010] Furthermore, each set of springs is respectively sleeved with each set of sleeves and rods, and the cross section of the mounting plate is semi-circular.

[0011] Furthermore, the disassembly assembly includes a connecting frame A fixed inside the buffer plate, and a connecting frame B fixed outside the mounting plate. Both the connecting frame A and the connecting frame B are threaded with a bolt that extends through to the outside of the buffer plate.

[0012] Furthermore, the connecting frame A is L-shaped, and the connecting frame B is inverted L-shaped.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. When the impact plate of this anti-collision utility frame is impacted, the impact plate will transfer the impact force to the mounting plate. The mounting plate will then compress the two springs, causing them to deform. The mounting plate will then push the sleeve rod into the sleeve and generate damping, thereby mitigating the impact on the impact plate and effectively protecting vehicles and pedestrians from impacts with the utility frame.

[0015] 2. When the impact-resistant cable tray deforms due to an impact, simply tightening the three bolts will cause them to unscrew from connecting brackets B and A, thus stopping the restriction on the mounting plate and the buffer plate. This allows for the disassembly of the buffer plate and the installation of a new one, avoiding the inconvenience of replacing the buffer plate when it deforms. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 An anti-collision cable rack in this embodiment includes a cable rack body 1 and four buffer plates 4 arranged in a ring. A cone-shaped fixing block 2 is fixed on the outer surface of the cable rack body 1. An installation plate 3 for fixing the cable rack body 1 is fixed on the bottom surface of the cable rack body 1. A buffer assembly is fixed on the outer surface of the cable rack body 1. Each of the four buffer plates 4 is equipped with a disassembly assembly.

[0022] Please see Figure 2To cushion the impact of vehicles or pedestrians on the power line frame body 1, the cushioning assembly in this embodiment includes four sets of two sleeves 5 fixed to the outer surface of the power line frame body 1. A sleeve rod 6 is sleeved inside the sleeve 5. An installation plate 8 is fixed to the other end of the sleeve rod 6. Four sets of two springs 7 are fixed between the installation plate 8 and the power line frame body 1. Each set of springs 7 is sleeved with each set of sleeves 5 and sleeve rod 6. The cross section of the installation plate 8 is semi-circular.

[0023] The buffer assembly also includes a connecting rod 9 fixed inside the mounting plate 8, and a slider 10 is fixed to the other end of the connecting rod 9.

[0024] Furthermore, in order to improve the stability of the buffer plate 4 when it is moved by an impact, the bottom surface of the fixing block 2 is provided with four sliding grooves, and four sliders 10 are located inside the four sliding grooves and are slidably connected to them. The sliding grooves and sliders 10 are all T-shaped.

[0025] When a pedestrian or vehicle impacts the main body 1 of the utility pole, the impact force is first transmitted to the mounting plate 8 through the buffer plate 4. The mounting plate 8 then compresses the spring 7 fixed to the other end of the mounting plate 8, causing the spring 7 to deform and thus mitigating the impact. When the spring 7 is compressed, the mounting plate 8 will cause the sleeve rod 6 to retract into the sleeve 5, thereby generating damping to prevent the spring 7 from rebounding. This prevents the spring 7 from rebounding and causing the buffer plate 4 to rebound, which could result in secondary injuries to pedestrians or vehicles impacting the buffer plate 4.

[0026] Please see Figure 3 In order to replace the buffer plate 4 that has been deformed by the impact, the disassembly assembly in this embodiment includes a connecting frame A11 fixed inside the buffer plate 4 and a connecting frame B12 fixed outside the mounting plate 8. Both the connecting frame A11 and the connecting frame B12 are threaded with a bolt 13 that extends through to the outside of the buffer plate 4.

[0027] To enable the connectors A11 and B12 to fit together, connector A11 is L-shaped and connector B12 is an inverted L-shape.

[0028] When the buffer plate 4 is deformed by an impact, the bolt 13 is first turned. When the bolt 13 rotates, it will unscrew from the connecting bracket A11 and connecting bracket B12 that are threadedly connected to the bolt 13, thereby stopping the limiting of the mounting plate 8 and the buffer plate 4. Then, a new buffer plate 4 can be replaced. When replacing the buffer plate 4, simply align the connecting bracket A11 and connecting bracket B12, and then screw the bolt 13 into the connecting bracket A11 and connecting bracket B12 to install the new buffer plate 4, thus improving the efficiency of replacing the buffer plate 4.
