[0002] As an important safety protection facility and isolation equipment, guardrails have the following main uses: I. Basic Security Functions 1. Physical barriers separate motor vehicles, non-motor vehicles, and pedestrians, enabling separate traffic lanes (such as bridge railings). This prevents vehicles from going off the road or entering the oncoming lane, reducing the risk of bridge falls and collisions.

[0003] 2. Collision protection: Using structures such as corrugated beams and pillars, the collision energy is absorbed, guiding out-of-control vehicles back to their normal driving direction. The crash barriers at the school gate can block out-of-control vehicles and protect the safety of teachers and students. II. Traffic Management Functions 1. Warnings and guidance Reflective strips and contoured designs alert drivers to road conditions, which is especially important at night.

[0004] Guide traffic flow in complex road sections to reduce arbitrary lane changes or driving against traffic. 2. Maintaining order Violent restrictions on dangerous behaviors such as pedestrians crossing the road can reduce the accident rate. Movable barriers at school gates can flexibly manage the separation of pedestrians and vehicles during peak hours.

[0041] The support pin 33 has a mounting ring 35 at the top and a limit hole at the bottom, where a limit pin 36 is installed.

[0042] The overall movable component of the guardrail is designed and used for guardrails 4 that are segmented and grouped (more than 1 piece) and are inconvenient to disassemble and relocate and need to be moved frequently. The guardrail 4 is relatively long; the ground where the guardrail is located and the area to which it is to be moved is flat.

[0043] The specific steps for moving the guardrail are as follows: Step 1: Install multiple anti-tipping outriggers 3 on both sides of the guardrail 4, move multiple lifting support components 2 to the lower part of the lower crossbeam of the guardrail 4 to be moved, and raise the lifting support components 2 to fit against the lower crossbeam of the guardrail 4. The guardrail 4 is composed of multiple segments, with multiple anti-tipping legs 3 installed on both sides of each segment. Pull out the leg pins 33, align the opening of the connecting fork 32 with the lower crossbeam of the guardrail 4, insert the connecting fork 32 into the lower crossbeam, then insert the leg pins 33 into the leg pin holes, and insert the limiting pins 36 into the limiting holes of the leg pins 33.

[0044] In order to stabilize the lifting of the guardrail 4, a limiting plate 27 is installed on the top of the bracket 24 of the lifting support component 2. The limiting blind hole 273 at the bottom of the limiting plate 27 is installed on the limiting post. The lifting support component 2 is operated to lift the bracket 24 and the limiting plate 27. The bottom of the guardrail 4 fits into the U-shaped groove 271 at the top of the limiting plate 27.

[0045] Step 2: Assign operators to each of the multiple lifting support components 2, issue operating commands, and have all operators simultaneously operate the lifting support components 2 to lift the guardrail 4, and move the mobile carrier 1 to the bottom of the guardrail 4's uprights. The guardrail 4 has a base at the bottom of its uprights. The guardrail 4 should be lifted to a height sufficient to allow the mobile vehicle 1 to move beneath it. It should not be lifted too high. At this point, the jack component 22 is in a high-position locked state. The operator of the lifting support component 2 pushes the mobile vehicle 1 under the base of the guardrail 4. The limiting plate 16 at the rear of the mobile vehicle 1 fits against the edge of the guardrail base. The limiting block 17 is then inserted into the limiting hole. Two operators then go to the other side of the guardrail 4 to insert the limiting block 17 of the mobile vehicle 1 into the corresponding limiting hole to prevent the guardrail 4 from slipping from the mobile vehicle 1 during movement.

[0046] Operation process of lifting support component 2: Insert the force rod 224 into the sleeve, rotate the force rod 224 up and down, the telescopic column of the jack 221 extends, press down the rear end of the rocker arm 23, the bracket 24 at the front end of the rocker arm 23 rises, and the U-shaped groove 271 of the limiting plate 27 fits with the lower crossbeam of the guardrail 4.

[0047] Step 3: Issue the operation command, and all operators simultaneously operate the lifting support component 2 to lower the guardrail 4. The guardrail base falls on the mobile vehicle 1, and all lifting support components 2 are removed. All operators simultaneously operate the hydraulic valve of jack 221, which is slowly released. The telescopic column of jack 221 retracts, the bracket 24 at the front end of lever 23 descends, and the guardrail base lands on the mobile vehicle 1.

[0048] All personnel operating the lifting support component 2 return to their operating positions. Upon receiving the operating command from the dispatcher, the bracket 24 of the lifting support component 2 is lowered simultaneously (note that the jack component 22 should be released slowly to ensure that the guardrail 4 descends slowly). At this time, the base of the guardrail 4 rests on the base plate 12 of the mobile carrier 1. Then, all lifting support components 2 are removed and placed in the equipment storage area for future use.

[0049] Step 4: Issue an operation command and simultaneously push multiple mobile vehicles 1 to move the guardrail 4 to the designated position; All operators return to position 4 of the guardrail and stand alternately on the left and right sides. There must be at least one person on each guardrail 4. When the operator issues the operation command, the moving vehicle 1 is pushed to move the guardrail 4 to the desired location. The guardrail 4 begins to move (note that the speed should be controlled during the movement and should not be too fast) until the guardrail 4 stops at the designated location.

[0050] Step 5: After the guardrail 4 reaches the designated position, move multiple lifting support components 2 to the lower part of the lower crossbeam of the guardrail 4, issue an operation command, and all operators simultaneously operate multiple lifting support components 2 to lift the guardrail 4, remove the moving vehicle 1, and then simultaneously operate multiple lifting support components 2 to lower the guardrail 4 to the ground, and remove the lifting support components 2 and the anti-tipping outriggers 3.

[0051] The lifting support component 2 raises the guardrail 4 until the guardrail base is above the base plate 12 of the mobile vehicle 1, at a height sufficient for the mobile vehicle 1 to be pushed away. The limiting block 17 is then removed. After the mobile vehicle 1 leaves the guardrail, the limiting block 17 is reinstalled into the limiting hole on the base plate 12. All mobile vehicles 1 are then placed in the equipment storage area for future use.

[0052] All operators returned to the position of the lifting support component 2. After issuing the operation command, they simultaneously and slowly released the oil valve, lowered the lifting support component 2, and removed the lifting support component 2 after the guardrail 4 was stably placed on the ground.

[0053] Remove all anti-tipping outriggers 3 from the guardrail 4 and place them together with the mobile vehicle 1 in the equipment storage area for future use.

[0054] The terminology used in this invention is descriptive and exemplary, and not restrictive. Since this invention can be embodied in various forms without departing from the spirit or essence of the technical solution, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
