Description
Technical Field
[0001] This utility model relates to the field of corrugated beam guardrail technology, and in particular to a portable and easy-to-install corrugated beam guardrail. Background Technology
[0002] Corrugated beam guardrails are a type of movable steel guardrail made of combined corrugated plates used at openings in the median strip of highways. These guardrails typically consist of corrugated beam guardrail panels for protection, shock absorbers for cushioning and energy absorption, and support posts for support. They are commonly used for roadside protection in landscaping projects. When a vehicle collides with a corrugated beam guardrail, its excellent impact resistance and energy absorption properties prevent it from being easily destroyed, while simultaneously providing excellent protection for the vehicle and its occupants.
[0003] Traditional corrugated beam guardrails typically use bolts or welding to install the guardrail blocks and guardrail panels. These methods are not only complex to operate, but also require specialized installation tools and equipment. For example, when using bolts, the bolts must first be passed through the connection holes between the guardrail block and the corrugated guardrail panel, then a nut is attached to one end of the bolt, and the bolt is rotated using tools such as wrenches. This results in low installation efficiency. When using welding, specialized tools are required for welding, and the exhaust fumes generated at the welding site can easily pollute the surrounding environment. Utility Model Content
[0004] This utility model addresses the shortcomings of traditional corrugated beam guardrails, which typically use bolted or welded connections to install the guardrail blocks and guardrail panels. These methods are not only complex to operate but also require specialized installation tools and equipment. This utility model provides a portable and easy-to-install corrugated beam guardrail, with the specific technical solution as follows:
[0005] A portable and easy-to-install corrugated beam guardrail includes a post, a blocking block fixed to one side of the top of the post, and a corrugated guardrail panel detachably mounted on one side of the blocking block. A connecting mechanism is provided between the blocking block and the corrugated guardrail panel. The connecting mechanism includes two sets of square rods movably mounted inside the corrugated guardrail panel and a stop block fixed to one end of the square rods for pressing the corrugated guardrail panel against the blocking block. The other end of the square rods is inserted into the blocking block. The top and bottom of the blocking block are provided with self-locking mechanisms for automatically locking and fixing the installed square rods.
[0006] By adopting the above technical solution, square rods are inserted into the corrugated guardrail panels and anti-blocking blocks, and the square rods are locked and fixed by a self-locking mechanism to connect and fix the corrugated guardrail panels and anti-blocking blocks. This allows people to complete the installation process simply by inserting the square rods completely into the corrugated guardrail panels and anti-blocking blocks.
[0007] Optionally, a hollow groove is provided inside the column, and two sets of symmetrically distributed and inclined reinforcing rods are fixed inside the hollow groove.
[0008] By adopting the above technical solutions, the hollow groove can reduce the weight of the column, thereby reducing the overall weight of the corrugated beam guardrail, making it easier to carry and transport, and the reinforcing bar can strengthen the interior of the column.
[0009] Optionally, the corrugated guardrail has two sets of square holes evenly spaced inside, and the square rod is movably connected to the square holes of the corrugated guardrail. The top and bottom of the anti-blocking block have two sets of slots evenly distributed, and one end of the square rod is inserted into the slot of the anti-blocking block.
[0010] By adopting the above technical solution, the anti-blocking block can be connected to and limited by the slot on the opposite rod.
[0011] Optionally, a limiting groove is provided in the slot of the anti-blocking block, and the self-locking mechanism includes a spring fixedly disposed in the limiting groove of the anti-blocking block, and a trapezoidal block fixedly disposed at one end of the spring and slidably connected in the limiting groove. A triangular groove is provided on the outer wall of the square rod, and the triangular end of the trapezoidal block is fitted into the triangular groove of the square rod. An external pull member is fixedly provided on the side of the trapezoidal block away from the square rod, extending through and to the outside of the anti-blocking block. A guide slope is provided at the end of the square rod near the trapezoidal block.
[0012] By adopting the above technical solution, the guide slope can press and guide the trapezoidal block when the square rod is inserted into the anti-blocking block, so that the trapezoidal block can be slowly pushed open and automatically inserted into the square rod under the spring force to complete the self-locking.
[0013] In summary, this utility model has at least one of the following beneficial effects:
[0014] 1. By inserting square bars into the corrugated guardrail panels and anti-blocking blocks, and using a self-locking mechanism to lock and fix the square bars, the corrugated guardrail panels and anti-blocking blocks are connected and fixed. This allows people to complete the installation process simply by inserting the square bars completely into the corrugated guardrail panels and anti-blocking blocks. Compared with bolt connections and welding, this method is more convenient, simplifies the installation process of corrugated beam guardrails, eliminates the need for professional installation equipment, and improves installation efficiency.
[0015] 2. The hollow groove reduces the weight of the posts, thereby reducing the overall weight of the corrugated beam guardrail, making it easier to carry and transport. The reinforcing rod strengthens the inside of the posts, ensuring their internal strength and preventing them from bending after impact. The corrugated guardrail panels can be disassembled by pulling the outer pull piece outward and removing the lower rod, making the disassembly and assembly process relatively convenient and quick.

[0020] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.
[0021] This utility model discloses a portable and easy-to-install corrugated beam guardrail, referring to... Figure 1-2 The system includes a post 1, a blocking block 2 fixedly installed on one side of the top of the post 1, and a corrugated guardrail 3 detachably installed on one side of the blocking block 2. The post 1 can support the blocking block 2 and the corrugated guardrail 3. The blocking block 2 can connect the post 1 and the corrugated guardrail 3. The blocking block 2 can absorb energy by deforming when a vehicle is hit. The corrugated structure of the corrugated guardrail 3 has good impact resistance and can absorb impact energy by deforming. The principles of the blocking block 2 and the corrugated guardrail 3 are all public technologies and will not be described in detail here.
[0022] Reference Figure 2 The column 1 has a hollow groove 11 inside, and two sets of symmetrically distributed and inclined reinforcing rods 12 are fixed in the hollow groove 11. Two sets of square holes are evenly opened in the square rod 4. The square rod 4 is movably connected in the square holes of the square rod 4. The hollow groove 11 can reduce the weight of the column 1, thereby reducing the overall weight of the corrugated beam guardrail, making it easier to carry and transport. The reinforcing rods 12 can strengthen the inside of the column 1, ensuring the internal strength of the column 1, so that the column 1 is not easy to bend after impact.
[0023] Reference Figure 1-3 A connecting mechanism is provided between the anti-blocking block 2 and the corrugated guardrail 3. The connecting mechanism includes two sets of square rods 4 movably installed inside the corrugated guardrail 3, and a stop block 41 fixed at one end of the square rods 4 for pressing the corrugated guardrail 3 against the anti-blocking block 2. The other end of the square rods 4 is inserted into the anti-blocking block 2. The square rods 4 can initially connect the anti-blocking block 2 and the corrugated guardrail 3. The stop block 41 cooperates with the corrugated guardrail 3 to abut against it. The corrugated guardrail 3 and the anti-blocking block 2 cooperate to abut against each other. The stop block 41 can press and limit the corrugated guardrail 3.
[0024] Reference Figure 2-3Two sets of square holes are evenly provided inside the corrugated guardrail panel 3. The square rod 4 is movably connected in the square holes of the corrugated guardrail panel 3. The corrugated guardrail panel 3 can support and limit the square rod 4 through the square holes, so that the square rod 4 can move laterally on the corrugated guardrail panel 3 but cannot rotate.
[0025] Reference Figure 2-3 The top and bottom of the anti-blocking block 2 are provided with two sets of evenly distributed slots 21. One end of the square rod 4 is inserted into the slot 21 of the anti-blocking block 2. The slot 21 end of the anti-blocking block 2 is solid. After one end of the square rod 4 is inserted into the slot 21, the anti-blocking block 2 can be connected to the corrugated guardrail 3.
[0026] Reference Figure 2-3 The top and bottom of the antiblock 2 are provided with self-locking mechanisms for automatically locking and fixing the installed square rod 4. The slot 21 of the antiblock 2 has a limit groove 22. The self-locking mechanism includes a spring 5 fixedly installed at the limit groove 22 of the antiblock 2, and a trapezoidal block 51 fixedly installed at one end of the spring 5 and slidably connected in the limit groove 22. The antiblock 2 can be limited by the limit groove 22 and the trapezoidal block 51. The trapezoidal block 51 is a right trapezoid with one end of the right trapezoid being triangular. Under the elastic force of the spring 5, the trapezoidal block 51 will be pushed towards the square rod 4.
[0027] Reference Figure 2-3 The outer wall of the square rod 4 has a triangular groove 42. The triangular end of the trapezoidal block 51 is inserted into the triangular groove 42 of the square rod 4. Under the elastic force of the spring 5, the triangular end of the trapezoidal block 51 will be inserted into the triangular groove 42 to lock and fix the square rod 4, thereby fixing the connection between the anti-blocking block 2 and the wave guardrail 3.
[0028] Reference Figure 2-3 A pull member 52 is fixedly provided on the side of the trapezoidal block 51 away from the square rod 4, extending through and to the outside of the anti-blocking block 2. The pull member 52 can be a thin steel wire rope or a pull rod, etc. People can pull the pull member 52 to the outside of the anti-blocking block 2, so that the trapezoidal block 51 is disengaged from the triangular groove 42, thereby disengaging the square rod 4 from the lock, making it convenient for people to pull out the square rod 4 to remove the corrugated guardrail plate 3 on the anti-blocking block 2.
[0029] Reference Figure 2-3 The square rod 4 has a guide slope 43 at one end near the trapezoidal block 51. The guide slope 43 can press and guide the trapezoidal block 51 when the square rod 4 is inserted into the anti-blocking block 2, so that the trapezoidal block 51 can be slowly pushed open and automatically inserted into the square rod 4 under the elastic force of the spring 5 to complete the self-locking.
[0030] The implementation principle of a portable and easy-to-install corrugated beam guardrail according to an embodiment of this utility model is as follows:
[0031] During installation, people can place the corrugated guardrail 3 against the anti-blocking block 2, and then insert the square rods 4 one by one into the square holes of the corrugated guardrail 3 and the slots 21 of the anti-blocking block 2. As the square rods 4 are inserted, the guide slope 43 will contact the trapezoidal block 51. As the square rods 4 are continuously inserted, the guide slope 43 will press and guide the trapezoidal block 51, so that the trapezoidal block 51 can be slowly pushed open.
[0032] When the triangular groove 42 is aligned with the trapezoidal block 51 as the square rod 4 is continuously inserted, the triangular end of the trapezoidal block 51 will be inserted into the triangular groove 42 under the elastic force of the spring 5 to lock and fix the square rod 4. The locking of the square rod 4 cooperates with the limiting block 41 to fix the connection between the anti-blocking block 2 and the wave guardrail 3, thus completing the installation process.
[0033] This allows people to complete the installation process simply by inserting the square rod 4 completely into the square corrugated guardrail plate 3 and the anti-blocking block 2, simplifying the installation process of the corrugated beam guardrail. No professional installation equipment is required, making installation easy and convenient.
