After the guide plate 30 makes the control mechanism 11 find the correct position, the control cylinder 24 slowly starts without excessively interfering with the posture of the control mechanism 11 after it has found the correct position. At this time, the guide plate 30 slowly leaves the outer surface of the connecting sleeve 19, and the guide pin 15 is replaced to cooperate with the inside of the connecting sleeve.

[0038] Advantageously, one side of the template 13 is open and the other side is closed, and the connecting sleeve 19 is located on the side of the side plate 12 close to the open side of the template 13; the width of the open side of the template 13 is greater than the width of the closed side. The material and shape of the template 13 are designed so that the center of gravity of the empty template 13 is located on the closed side, and the open side of the template 13 can accommodate more concrete, so the center of gravity of the template 13 fully loaded with concrete is located on the open side. In this way, the empty template 13 can be opened upward to facilitate the pouring of concrete, and at the same time, the quality defects such as honeycomb and rough surface of the central dividing guardrail obtained by molding can be effectively improved, while the fully loaded template 13 is convenient for demoulding with the open side facing downward.

[0039] Working principle of the present invention:

[0040] In the initial state, the open side of the empty template 13 faces upward; it is lifted to the specified position by the control mechanisms 11 at both ends, concrete is poured into it, and it is simply sealed. After the concrete is formed, it is lifted by the control mechanisms 11 at both ends, the template 13 is turned over and demolded, and after disassembling the template 13 and the side panels 12, a central dividing zone guardrail with a Y-shaped cross-section is obtained.

[0041] In the above process, when the control mechanism 11 is matched with the side plate 12, the control mechanisms 11 on both sides are first placed near the side plate 12 by the gantry crane and the steel rope 14, and the guide pins 15 of the landing plate 17 are in contact with the ground;

[0042] The position of the control mechanism 11 is roughly adjusted by controlling the gantry crane, during which the roller 41 and the ground roll until the guide plate 30 is located at the lower side of the connecting sleeve 19 and stops; at this time, the steel rope 14 is slowly wound, and the steel rope 14 lifts the control mechanism 11 as a whole through the connecting piece 35, the load-bearing rod 23 and the connecting block 16.

[0043] During the lifting process of the control mechanism 11, the two guide plates 30 contact the side of the connecting sleeve 19, gradually guiding the control mechanism 11 to swing until the connecting sleeve 19 is centered between the two guide plates 30, and at the same time, the floating bracket 38 contacts the connecting sleeve 19, the guide pin 15 and the connecting sleeve 19 are basically coaxially corresponding, and then the winding of the steel rope 14 is suspended;

[0044] Start the control cylinder 24, which controls the piston rod to retract, driving the sliding rod 40 to slide relative to the connecting block 16, and the floating bracket 38 and the connecting plate 25 slide together with the sliding rod 40. At the same time, the limiting rod 29 slides relative to the connecting block 16, and the pressure spring 28 is compressed. During the sliding process, the connecting plate 25 drives the guide pin 15 to move through the rotating rod 22, and the guide pin 15 and the limiting column 20 slide. The guide pin 15 gradually approaches the connecting sleeve 19. Under the guidance of the guide part 36, the guide pin 15 gradually enters the connecting sleeve 19, and the guide pin 15 and the connecting sleeve 19 are connected. After the guide pin 15 moves to the maximum position, the control cylinder 24 stops working.

[0045] At this time, the tension of the steel rope 14 acts on the side plate 12 through the connecting block 16, the front extension rod 37, the mounting rod 21, the limit column 20, the guide pin 15 and the connecting sleeve 19. Continuing to wind the steel rope 14 will lift the template 13.

[0046] After the template 13 is lifted to a certain height, the control motor 27 is started. The control motor 27 controls its output shaft to rotate, driving the friction wheel 18 to rotate. After the friction wheel 18 contacts the connecting sleeve 19, an external force is applied to the connecting sleeve 19 to rotate. At this time, the center of gravity of the template 13 is facing upward, and the connecting sleeve 19 can be flipped over by a very small external force. When flipping, the connecting sleeve 19 and the guide pin 15 rotate.

[0047] After the flipping is completed, the open side of the template 13 faces downward. Since the open side is sealed with rods after the concrete is poured, and there is friction between the concrete and the side wall of the template 13, the concrete guardrail will not fall out directly during the flipping process. It is necessary to remove the side panel 12 and knock on the template 13 to demold it.

[0048] Before demoulding, the control mechanism 11 is reset in the same manner as above; loosening the steel rope 14 can allow the open side of the template 13 to fall back and touch the ground again. When the steel rope 14 is slightly loose, the operation is suspended, and the control cylinder 24 is started to control the extension of its piston rod. Under the action of the rotating rod 22, the guide pin 15 slides out of the connecting sleeve 19, and then the steel rope 14 is continued to be loosened until it falls to the ground on the landing plate 17.

[0049] After demoulding, the template 13 and the side panel 12 are cleaned and reassembled with the open side facing downward. The same principle as above is used to lift them using the control mechanisms 11 on both sides. Since the center of gravity of the empty template 13 is on the closed side, after applying a rotational external force to the connecting sleeve 19, the template 13 can be easily flipped over to have the open side facing upward.
