[0032] 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.
[0033] As attached Figure 1 To be continued Figure 8 The movable guardrail shown includes a bracket 3. Multiple brackets 3 are vertically installed on the ground according to the road length. An upper crossbeam 2 is installed on the top of the bracket 3, and two lower crossbeams 1 are installed on the side of the bracket 3. The brackets 3, upper crossbeams 2 and lower crossbeams 1 are laid and installed along the road according to the road length to form a movable guardrail.
[0034] The upper crossbeam 2 has a U-shaped cross-section, and the two lower crossbeams 1 have two continuous 90-degree rolled edges on their sides.
[0035] To ensure good mobility and flexibility of the mobile guardrail, two support plates 303 are set on both sides of the bottom of the bracket 3. The upper support plate 303 is longer than the lower support plate 303 to better support the two lower crossbeams 1. At the same time, a fixing plate 301 is set at the bottom of the bracket 3, and ribs 302 are set on the top surface of the fixing plate 301 and the side of the bracket 3. The side of the rib 302 has a chamfered structure, and the beveled surface of the chamfer is used to support the bottom of the lower crossbeam 1.
[0036] The two ends of the fixing plate 301 are fixed to the ground by bolts or pins.
[0037] During installation, the two lower crossbeams 1 are supported by the support plate 303 from bottom to top and are connected to each other by two symmetrical bent plates 7.
[0038] like Figures 4 to 8 As shown, the cross-section of the main body of the bending plate 7 is also set as a "U" shaped structure, and the free edges on both sides of the bending plate 7 extend into a beveled edge 703 structure. A plug-in plate 707 is provided in the groove of the bending plate 7. The plug-in plates 707 of the two bending plates 7 are staggered vertically to facilitate the splicing of the two bending plates 7.
[0039] Both the plug-in plate 707 and the plug plate 705 are provided with through holes, and the two bent plates 705 can be inserted into the through holes to connect them into a whole.
[0040] Connecting plates 701 are provided on the inclined side 703 of the bending plate 7 and on the sides of both ends of the lower crossbeam 1. The connecting plates 701 on the bending plate 7 and the connecting plates 701 on the lower crossbeam 1 are staggered vertically. After the lower crossbeam 1 and the bracket 3 are pre-installed, the bending plate 7 is placed at both ends of the lower crossbeam 1, and pins 704 are inserted into the connecting plates 701 to fix the lower crossbeam 1 to the bracket 3.
[0041] To facilitate the installation of the bent plate 7, right-angle notches 702 are made in the middle of the inclined side 703 of the bent plate 7, as well as at the top and bottom ends. The rolled edges on both sides of the lower crossbeam 1 are placed at the right-angle notches 702 for overlap.
[0042] The topmost insertion plate 707 of the bent plate 7 has a round hole, while the bottom insertion plate 707 has an oblong hole. After the second pin 705 is inserted into the insertion plate 707, a limiting pin 706 is inserted axially at the bottom of the second pin 705. Then, the second pin 705 is rotated. In this state, it cannot be pulled out from the outside. When replacing or maintaining the lower crossbeam 1, the second pin 705 can be rotated upwards to remove it. At the same time, the round hole of the top insertion plate 707 can also prevent the second pin 705 from being pulled out directly, which can play a certain role in preventing theft and preventing the second pin 705 from being easily pulled out.
[0043] like Figure 3 As shown, after the lower crossbeam 1 is installed, the upper crossbeam 2 is fastened to the top of the bracket 3 and fixed with bolts. The connection between the two upper crossbeams 2 is made by connecting sleeve 4. The connecting sleeve 4 is set with a "U" shape and is placed at the connection between the two upper crossbeams 2 and is placed inside to ensure the overall consistency of the guardrail appearance.
[0044] Anti-glare plate pre-reserved holes 5 are also provided at equal intervals on the upper crossbeam 2 for installing anti-glare plates.
[0045] To improve drainage after installation, the guardrail is raised compared to the existing guardrail. A base plate 10 is installed at the bottom of the bracket 3. A boat-shaped sliding plate 8 is connected to the bottom of the base plate 10 via a support leg 6. The support leg 6 is a C-shaped channel steel. The two ends of the support leg 6 are connected to the base plate 10 and the boat-shaped sliding plate 8. The boat-shaped sliding plate 8 contacts the ground to form support, ensuring the clearance between the lower crossbeam 1 and the ground, thus effectively improving the drainage effect.
[0046] End beams 9 are installed at both ends of the guardrail. One end of the end beam 9 is connected to the upper crossbeam 2 by bolts, and the other end is fixed to the ground by pins. One end of the lower crossbeam 1 extends into the interior of the end beam 9 after being slightly bent.
[0047] like Figure 1 and Figure 2 As shown, during the installation of the movable guardrail, one end beam 9 and the upper crossbeam 2 form a set of fixed sections. The entire fixed section is 3 meters long. Both ends of the guardrail are fixed sections. In the fixed sections, the bottom of the bracket 3 is installed as a fixed plate 301. The fixed plate 301 is inserted into the ground through pins to form a fixed structure.
[0048] The upper crossbeam 2 and the lower crossbeam 1 are 6 meters long as a whole. Two upper crossbeams 2 are installed as a standard section. The guardrail is equipped with multiple brackets 3 with fixing plates 301 at intervals of 12 meters to reinforce the installation of the guardrail and improve its anti-collision performance.
[0049] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
