[0019] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
[0020] Example 1
[0021] The anti-collision engineering guardrail described in this embodiment includes two columns 4 distributed front and back, and a guard plate 14 is installed between the two columns 4. The guard plate 14 has a blocking effect and has a certain anti-collision ability. Figure 3As shown, the left and right walls of the column 4 are both fixed with a clamping plate 13 for mounting a protective plate 14. The clamping plate 13 is in a "U"-shaped structure and has a through hole for bolts to pass through, so that the protective plate 14 and the clamping plate 13 are connected together by bolts. In actual application, there are several columns 4, and there is a protective plate 14 between two adjacent columns 4. Figure 3 As shown;
[0022] The right side of each of the columns 4 is fixed with a support column 5 for preventing the column 4 from bending after collision. Figure 1 As shown, the upper end of the column 4 is supported by the support column 5, thereby greatly improving the overall anti-collision performance of the device (the ability to be impacted without deformation or damage). At the same time, the lower end of each column 4 and the support column 5 is fixed with a bottom plate 1, and the bottom plate 1 is fixed to the ground by expansion screws, thereby further improving the overall anti-collision performance of the device;
[0023] like Figure 1 and Figure 3 As shown, a crash barrier 3 is provided on the left side of the protective plate 14, and the crash barrier 3 is the first contact point when a collision occurs;
[0024] Each column 4 is penetrated by two first mounting tubes 8 that are slidably matched with it left and right. As shown in 1, each first mounting tube 8 is horizontally arranged, and the first mounting tubes 8 on the same column 4 are distributed up and down;
[0025] The left ends of the four first mounting tubes 8 are all mounted on the crash barrier 3. Figure 1 , Figure 2 and Figure 3 As shown, the crash barrier 3 is provided with a plurality of bolts 6 corresponding to the first mounting tubes 8 one by one, and a fixing plate 7 for connecting the bolts 6 is fixed to the left end of each first mounting tube 8. In this embodiment, the bolts 6 are passed through the crash barrier 3 and screwed into the fixing plate 7 to achieve the connection between the first mounting tube 8 and the crash barrier 3, wherein the left end of the bolt 6 is an arc-shaped structure;
[0026] The left side wall of each support column 5 is fixed with two second mounting tubes 10 corresponding to the first mounting tubes 8 one by one. Each second mounting tube 10 is sleeved on the corresponding first mounting tube 8 and slides with it left and right. Figure 1 As shown, in this embodiment, the first mounting tube 8 can slide left and right along the column 4, and can also slide left and right along the second mounting tube 10. The two second mounting tubes 10 on the support column 5 are also distributed up and down, and the second mounting tubes corresponding to the first mounting tube 8 are all located on the right side of the first mounting tube 8;
[0027] like Figure 1As shown, one end of the second mounting tube 10 sleeved on the corresponding first mounting tube 8 is fixed to the column 4 where the first mounting tube 8 is located by welding or bolts, thereby further enhancing the anti-collision performance of the device;
[0028] The first mounting tube 8 and the second mounting tube 10 are respectively fixed with a first connecting plate 9 and a second connecting plate 11, and a spring 12 is fixed between the corresponding first connecting plate 9 and the second connecting plate 11. When the spring 12 is in a natural state, a certain distance is left between the crash barrier 3 and the column 4. In this embodiment, the energy of the impact is absorbed by the contraction of the spring 12, thereby preventing multiple conventional impacts from directly hitting the column 4 and preventing the crash barrier 3 from being deformed due to full force, thereby improving the service life of the device; Figure 2 As shown, one end of the spring 12 is fixed on the first connecting plate 9, and the other end is fixed on the second connecting plate 11, wherein the first connecting plate 9 is integrally formed with the first mounting tube 8 or fixed by welding, and similarly, the second mounting tube 10 and the second connecting plate 11 are integrally formed or fixed by welding;
[0029] The minimum distance between the crash barrier 3 and the pillar 4 is smaller than the maximum compression amount of the spring 12, so that when a collision occurs, the crash barrier 3 can be ensured to contact the pillar 4 within the elastic limit of the spring 12, and the spring 12 is prevented from being subjected to a huge impact and being permanently damaged;
[0030] The anti-collision barrier 3, the first mounting tube 8, the second mounting tube 10, the first connecting plate 9, the second connecting plate 11 and the spring 12 in this embodiment constitute the anti-collision mechanism for absorbing the energy generated by the collision. In practical application, the first mounting tube 8 can also be selected to have a closed right end, and the end of the spring 12 originally fixed to the first connecting plate 9 is directly fixed to the closed end of the first mounting tube 8.
[0031] like Figure 1 and Figure 3 As shown, the crash barrier 3 is a corrugated steel guardrail plate, which is commonly used in the central isolation zone or curb of various highways to play an isolation and protection role. Due to the unique corrugated structure with good collision resistance and energy absorption function, it can gradually deform after being hit and contacting the column 4 (in this embodiment, the force required to deform the crash barrier 3, the column 4 and the support column 5 is greater than the maximum elastic force of the spring 12), so that it is not easy to be destroyed and can provide good protection for the vehicle and the driver and passengers.
[0032] When this embodiment is used, first, the columns 4 and the support columns 5 are respectively inserted into the preset holes and fixed with cement or the like, and at the same time, the base plate 1 is fixed to the ground with expansion screws, and then the protective plate 14 is installed between the two columns 4. Then, when a collision occurs, the anti-collision barrier 3 is impacted, and the first mounting tube 8 slides into the second mounting tube 10 and drives the spring 12 to compress. If the collision force is small, the anti-collision barrier 3 does not contact the column 4 or contacts but does not deform the anti-collision barrier 3 and the column 4. The device does not need to be repaired, and the entire anti-collision mechanism absorbs the energy of the collision. If the collision force is large, the anti-collision barrier 3 contacts the column 4, and then the anti-collision barrier 3, the column 4, and the support column 5 will absorb energy through deformation in turn and prevent the continued movement of the impacting object, thereby protecting personnel and equipment at the construction site from collision.
[0033] Example 2
[0034] This embodiment further illustrates the technology. The anti-collision mechanism has two groups and is distributed in an upper and lower manner. Figure 1 and Figure 3 As shown, the present embodiment adopts two sets of anti-collision mechanisms distributed in an upper and lower manner. The upper anti-collision mechanism can perform secondary absorption of the impact energy for larger vehicles, thereby further increasing the impact force that causes the anti-collision barrier 3 to contact the pillar 4. When the anti-collision mechanism below is damaged due to a collision with a small vehicle, the upper anti-collision mechanism or the anti-collision barrier 3 can be replaced with the lower one, thereby achieving the purpose of emergency replacement.
[0035] Example 3
[0036] This embodiment further illustrates the technology. The left side wall of the crash barrier 3 is equipped with several reflective signs 2, such as Figure 1 and Figure 3 As shown, the reflective mark 2 can provide reflective reminders to passing vehicles at night, thereby improving the anti-collision ability of the device at night.
