Description

Technical Field

[0001] This utility model relates to a highway warning sign installation and fixing device, specifically a device for quick installation, disassembly and fixing of highway concrete guardrail warning signs, belonging to the technical field of highway warning sign installation and fixing. Background Technology

[0002] Highway warning signs are facilities that use graphic symbols and text to convey specific information, manage traffic, indicate directions, and ensure road safety and smooth flow. They have legal force and must be obeyed by both vehicles and pedestrians. They are mainly divided into main signs and auxiliary signs. The main signs include four categories: warning, prohibition, instruction, and direction, which correspond to the functions of warning of danger, prohibition of behavior, indicating travel, and conveying direction and location information, respectively. Highway warning signs are usually installed and fixed on both sides of the road using steel frames and fixing devices.

[0003] Chinese Patent Publication CN214245459U discloses a warning sign for highway construction. When the wind blows, the rotating plate causes the cross-shaped bracket to rotate the rotating column. Multiple rotating plates rotate back and forth, making the warning content area more conspicuous and the warning effect obvious. In addition, the solar light also provides illumination at night, ensuring the nighttime effect.

[0004] The aforementioned patented technology cannot quickly install highway construction warning signs onto concrete guardrails during highway construction and maintenance operations. The main reason is that the concrete guardrails were not designed with pre-drilled holes for the warning signs. Traditional installation methods involve drilling holes with an impact drill and fixing them with expansion bolts. This method is very cumbersome, requires many tools and installers, and can damage the structural strength of the concrete guardrail. Furthermore, it makes subsequent disassembly and recycling of the warning signs inconvenient. Therefore, this paper proposes a device for the rapid installation, disassembly, and fixing of highway concrete guardrail warning signs. Utility Model Content

[0005] This utility model proposes a device for the quick installation, disassembly, and fixing of highway concrete guardrail warning signs, in order to solve the problem in the prior art that highway construction warning signs cannot be quickly installed and fixed on the concrete guardrails on both sides of the highway, and that it is inconvenient to disassemble and recycle the warning signs later.

[0006] This utility model is achieved through the following technical solution: a device for quick installation, disassembly and fixing of warning signs for highway concrete guardrails, including a highway guardrail, an indicator sign on the right side of the highway guardrail, and an installation mechanism on the top of the highway guardrail;

[0007] The installation mechanism includes two frames, which are respectively set on both sides of the highway guardrail. The inner walls of the two frames are respectively fixedly connected to a telescopic frame and a telescopic cylinder. The telescopic cylinder is slidably connected inside the telescopic frame. The inner wall of the telescopic cylinder is threadedly connected to a screw. The left end of the screw passes through the telescopic frame and one of the frames in sequence and is fixedly connected to a handle. The inner wall of one of the frames is fixedly connected to two auxiliary frames. The interior of each of the two auxiliary frames is slidably connected to an auxiliary cylinder. The left side of each of the two auxiliary cylinders is fixedly connected to the inner wall of the other frame.

[0008] The highway guardrail is equipped with fastening components on its exterior, and the installation mechanism is equipped with splicing components on its right side.

[0009] The outer surface of the screw is threaded with a threaded cylinder, and the right side of the threaded cylinder is fixedly connected to the left side of the telescopic cylinder.

[0010] Two limiting rings are fixedly connected to the outer surface of the screw, and one side of each limiting ring contacts the left side and the inner wall of one of the frames, respectively.

[0011] Anti-detachment rings are fixedly connected to the outer surfaces of both auxiliary cylinders, and the two anti-detachment rings are slidably connected inside the two auxiliary frames respectively.

[0012] The fastening assembly includes two angle irons, with their opposite sides fixedly connected to the opposite sides of the two frames. Two limiting nuts are fixedly connected to the inner walls of the two angle irons, and each limiting nut has a tapered screw threaded inside. One end of each tapered screw is in contact with the outer surface of the highway guardrail.

[0013] The splicing assembly includes a sleeve disposed on the right side of the highway guardrail. The sign is disposed inside the sleeve. Two reinforcing ribs are fixedly connected to the outer surface of the sleeve. The left side of each of the two reinforcing ribs is fixedly connected to the right side of one of the frames. Two positioning bolts are threadedly connected inside the sleeve. Positioning nuts are threadedly connected to the outer surface of each of the two positioning bolts. The left side of each of the two positioning nuts is fixedly connected to the outer surface of the sleeve. A limit frame is fixedly connected to the outer surface of the sleeve. The outer surface of the limit frame contacts the bottom end of the sign.

[0014] This utility model provides a device for the quick installation, disassembly, and fixing of warning signs on highway concrete guardrails, which has the following beneficial effects:

[0015] 1. This device for quickly installing, dismantling, and fixing highway concrete guardrail warning signs utilizes an installation mechanism that uses two frames to clamp the guardrail from both sides. Manually turning the screw with a handle forces the telescopic cylinder into the telescopic frame. With the assistance of the auxiliary frame and cylinder, the two frames move closer together, quickly completing the installation of the highway construction warning sign. Reversing the screw quickly releases the sign, eliminating the need for drilling holes and using expansion bolts. This increases the ease of installation and removal of warning signs on highway concrete guardrails, reduces the number of personnel and tools required for installation, and does not damage the structural strength of the concrete guardrail, facilitating subsequent dismantling and recycling of the warning sign.

[0016] 2. This quick installation and disassembly fixing device for highway concrete guardrail warning signs improves the connection stability between the frame and the highway guardrail through fastening components. It uses triangular angle irons to cope with different guardrail wall angles (straight or sloping walls), increasing the contact area and maximizing the force. The tapered screws inserted into the highway guardrail can counteract the lateral force generated on the windward side after the warning sign is installed, further ensuring the installation stability of the warning sign. The splicing components can smoothly connect the sign to the fixing device, ensuring the ease of assembly of the sign and the fixing device. Attached Figure Description

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0030] Please see Figures 1-6 This utility model embodiment provides a device for quick installation, disassembly and fixing of warning signs for highway concrete guardrails, including a highway guardrail 1, an indicator sign 2 on the right side of the highway guardrail 1, and an installation mechanism 3 on the top of the highway guardrail 1.

[0031] The installation mechanism 3 includes two frames 301, which are respectively located on both sides of the highway guardrail 1. A telescopic frame 302 and a telescopic cylinder 303 are fixedly connected to the inner walls of the two frames 301, respectively. The telescopic cylinder 303 is slidably connected inside the telescopic frame 302. A screw 304 is threadedly connected to the inner wall of the telescopic cylinder 303. The left end of the screw 304 passes through the telescopic frame 302 and one of the frames 301 and is fixedly connected to a handle 305. Two auxiliary frames 306 are fixedly connected to the inner wall of one of the frames 301. The internal components of the screw 304 are slidably connected to auxiliary cylinders 307. The left side of each of the two auxiliary cylinders 307 is fixedly connected to the inner wall of another frame 301. The outer surface of the screw 304 is threadedly connected to a threaded cylinder 308. The right side of the threaded cylinder 308 is fixedly connected to the left side of the telescopic cylinder 303. The threaded cylinder 308 can increase the threaded contact area between the screw 304 and the telescopic cylinder 303, thereby ensuring the transmission stability between the screw 304 and the telescopic cylinder 303 and making the threaded connection between the screw 304 and the telescopic cylinder 303 less prone to loosening.

[0032] Please refer to this carefully. Figure 3Two limiting rings 309 are fixedly connected to the outer surface of the screw 304. One side of each limiting ring 309 contacts the left side and the inner wall of one of the frames 301, respectively. The limiting rings 309 can restrict the position of the screw 304 inside the left frame 301 while affecting the smooth rotation of the screw 304, thereby improving the rotation reliability of the screw 304.

[0033] Please refer to this carefully. Figure 3 The outer surfaces of the two auxiliary cylinders 307 are fixedly connected with anti-detachment rings 310. The two anti-detachment rings 310 are slidably connected inside the two auxiliary frames 306. The anti-detachment rings 310 can increase the sliding stability of the auxiliary cylinders 307 inside the auxiliary frames 306 and prevent the auxiliary cylinders 307 from detaching from the auxiliary frames 306.

[0034] Please refer to this carefully. Figure 2 and Figure 4 The highway guardrail 1 is externally equipped with a fastening assembly 4, which includes two angle irons 401. The opposite sides of the two angle irons 401 are fixedly connected to the opposite sides of the two frames 301. The inner walls of each angle iron 401 are fixedly connected with two limiting nuts 403. Each limiting nut 403 has a tapered screw 402 threaded inside. One end of each tapered screw 402 contacts the outer surface of the highway guardrail 1. When the frames 301 are clamped onto the highway guardrail 1, the angle irons 401 will also contact the highway guardrail 1. Furthermore, the angle iron 401 can adapt to different angles of the highway guardrail 1 wall, allowing it to be installed on straight or sloping highway guardrail 1 walls, increasing its contact area and maximizing its clamping and fixing force. Then, by rotating the tapered screw 402 in conjunction with the limiting nut 403, the tip of the tapered screw 402 can penetrate into the interior of the highway guardrail 1, thereby further improving the connection tightness between the frame 301 and the highway guardrail 1, which can counteract the lateral force generated on the windward side after the warning sign is installed, further ensuring the stability of the warning sign installation.

[0035] Please refer to this carefully. Figure 2 , Figure 5 and Figure 6The right side of the installation mechanism 3 is provided with a splicing component 5, which includes a sleeve 501. The sleeve 501 is located on the right side of the highway guardrail 1, and the sign 2 is located inside the sleeve 501. Two reinforcing ribs 505 are fixedly connected to the outer surface of the sleeve 501. The left side of each of the two reinforcing ribs 505 is fixedly connected to the right side of one of the frames 301. Two positioning bolts 502 are threadedly connected inside the sleeve 501. Positioning nuts 503 are threadedly connected to the outer surface of each of the two positioning bolts 502. The left side of each of the two positioning nuts 503 is fixedly connected to the sleeve 501. The outer surface of the sleeve 501 is fixedly connected to a limit bracket 504. The outer surface of the limit bracket 504 contacts the bottom end of the indicator 2. When the indicator 2 is inserted into the sleeve 501 until the bottom end of the indicator 2 contacts the limit bracket 504, the position of the indicator 2 and the frame 301 can be initially fixed by the sleeve 501 and the reinforcing rib 505. Then, the positioning bolt 502 is rotated in conjunction with the positioning nut 503 until one end of the positioning bolt 502 contacts the indicator 2, thus fixing the position of the indicator 2 very securely.

[0036] When using this utility model: First, the guardrail 1 is clamped from both sides by two frames 301. Then, the screw 304 is manually rotated by the handle 305 under the limit of the limiting ring 309. With the screw 304 connected to the telescopic cylinder 303 and the threaded cylinder 308, the telescopic cylinder 303 can be forced to retract into the telescopic frame 302. At this time, with the assistance of the auxiliary frame 306 and the auxiliary cylinder 307, the two frames 301 can be driven to move closer to each other.

[0037] When the frame 301 is clamped onto the highway guardrail 1, the angle iron 401 will also come into contact with the highway guardrail 1. The angle iron 401 can adapt to different angles of the highway guardrail 1 wall, so that it can be installed on the highway guardrail 1 on straight or sloping walls, increasing its contact area and maximizing its clamping and fixing force. Then, by rotating the tapered screw 402 in conjunction with the limit nut 403, the tip of the tapered screw 402 can be inserted into the interior of the highway guardrail 1, thereby further improving the connection tightness between the frame 301 and the highway guardrail 1, so as to counteract the lateral force generated on the windward side after the warning sign is installed, and further ensure the stability of the warning sign installation.

[0038] Furthermore, when the sign 2 is inserted into the sleeve 501 until the bottom of the sign 2 contacts the limit frame 504, the position of the sign 2 and the frame 301 can be initially fixed by the sleeve 501 and the reinforcing rib 505. Then, the positioning bolt 502 is rotated in conjunction with the positioning nut 503 until one end of the positioning bolt 502 contacts the sign 2, which can very firmly fix the position of the sign 2, thereby quickly completing the installation of the highway construction warning sign.

[0039] Finally, rotating screw 304 in the opposite direction quickly loosens the warning sign, eliminating the need to drill holes with an impact drill and install the warning sign with expansion bolts. This increases the ease of installation and removal of the warning sign on the highway concrete guardrail, reduces the number of personnel and tools required for installation, and does not damage the structural strength of the concrete guardrail, making it easier to disassemble the warning sign for recycling and reuse.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
