[0051] In this embodiment, the highway guardrail is transported and transferred by moving the mobile trolley 1, and the mechanical arm 2 is adjusted to facilitate the picking up of highway guardrails at different positions on the road surface or material yard. The highway guardrail can be sucked up by the electromagnetic suction cup 6, so that it can move with the free end of the auxiliary component 2, so as to facilitate its transportation to the installation site; the connecting plate 5 is driven to rotate by the turntable 4 so that the inclination and position of the highway guardrail meet the installation requirements; the auxiliary component 7 plays a buffering role when picking up the highway guardrail and adsorbs the highway guardrail. At the same time, after the electromagnetic suction cup 6 loses its magnetic force, it is convenient to support and position the highway guardrail, so that it is easy to fix during installation.

[0052] As a preferred embodiment, Figure 2 and Figure 3 As shown, the auxiliary component 2 includes:

[0053] A big arm 21, the big arm 21 is fixedly mounted on the upper side of the rotatable body 11 of the mobile vehicle 1, and a fixed pulley 27 is provided on the inner side of the upper end of the big arm 21;

[0054] Two rotating arms 22, the two rotating arms 22 are symmetrically arranged and both are rotatably mounted on the upper end of the large arm 21, and a connecting shaft 25 is also arranged between the two rotating arms 22;

[0055] A movable arm 23, wherein the movable arm 23 is rotatably disposed at a free end of the rotating arm 22 via a first motor 24;

[0058] As a preferred embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the turntable 4 is rotatably arranged at the free end of the movable arm 23 and is connected to the movable arm 23 via a second motor 41;

[0059] In this embodiment, the second motor 41 drives the turntable 4 to rotate, so as to adjust the installation angle of the highway guardrail.

[0060] As a preferred embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the connecting plate 5 is arranged at the front end of the turntable 4, and a second connecting hole 51 is arranged on the connecting plate 5. The second connecting hole 51 is used in conjunction with the first connecting hole 42 arranged on the turntable 4. During installation, the connecting bolt 8 is used to pass through the first connecting hole 42 and the second connecting hole 51 in sequence to install the connecting plate 5 at the front end of the turntable 4.

[0061] As a preferred embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the auxiliary components 7 are arranged around the electromagnetic chuck 6, the number of each group of auxiliary components 7 is not less than four, and the four auxiliary components 7 are distributed in a rectangular array;

[0062] In this embodiment, the highway guardrail can be adsorbed by starting the electromagnetic suction cup 6 for easy installation, which is simple to operate and effectively improves work efficiency; at the same time, after the highway guardrail is adsorbed by starting the electromagnetic suction cup 6, the turntable 4 can be driven to rotate by starting the motor 41 to achieve the effect of adjusting the angle of the highway guardrail, so as to adjust the position of the highway guardrail for installation. The symmetrical distribution of the electromagnetic suction cup 6 can increase stability when adsorbing the highway guardrail and avoid the offset caused by the large gravity at both ends of the guardrail when adsorbed in the middle of the highway guardrail.

[0063] As a preferred embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the auxiliary component 7 includes:

[0064] A negative pressure suction cup 71, which is disposed at the front end of the connecting plate 5 and connected to one end of the adjusting rod 72;

[0065] An adjusting rod 72, the adjusting rod 72 is movably arranged in the connecting tube 73, and is connected to an adjusting plate 74 arranged in the connecting tube 73, the adjusting plate 74 is arranged in the connecting tube 73 through a spring 75, and an adjusting cavity is formed between the side of the adjusting plate 74 away from the spring 75 and the inner wall of the connecting tube 23; a cavity 76 connected to the suction cup 71 is also provided inside the adjusting rod 72, and an air hole connecting hole 77 connected to the adjusting cavity is provided on the inner wall of the cavity 76, and the tail end air port of the connecting tube 73 is connected to the air pump 3 through a hose 9;

[0066] In this embodiment, during the process of the electromagnetic suction cup 6 adsorbing the guardrail plate, the shape of the highway guardrail plate is usually wavy, resulting in the electromagnetic suction cup 6 being able to only adsorb the raised part of the surface of the highway guardrail plate, and the contact area is small. By setting the auxiliary component 7, the suction cup 71 can be stuck into the concave part of the guardrail plate during the process of adsorbing the highway guardrail plate. As the adsorption proceeds, the highway guardrail plate will move toward the electromagnetic suction cup 6, so that the highway guardrail plate pushes the suction cup 71 to move toward the connecting plate 5. In this process, the adjusting rod 72 can be driven to retract into the interior of the connecting cylinder 73, and the adjusting plate 74 can be driven to squeeze. The spring 75 is compressed and the space inside the regulating chamber is increased at the same time. Since the air hole connecting hole 77 is connected to the regulating chamber, the low pressure formed during the increase of the internal space of the regulating chamber cooperates with the external air pressure to form an air pressure difference, and the mutual cooperation of the air hole connecting hole 77 and the cavity 76 enables the suction cup 71 to adsorb the guardrail, thereby enhancing the adsorption effect on the highway guardrail; when it is necessary to release the highway guardrail, gas is introduced into the connecting tube 73 through the hose 9, pushing the adjusting rod 72 to move forward until the air hole connecting hole 77 extends out of the connecting tube 73, thereby completing the release of the highway guardrail.

[0067] As a preferred embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the guardrail panel installation machine also includes an electronic monitoring eye, which is set at the top of the mechanical arm; a display screen, which is set in the operation room, is used to ensure the safe and accurate docking operation of the device when in use.

[0068] The working principle of the guardrail installation machine described in the utility model includes:

[0069] The guardrail board can be adsorbed by starting the electromagnetic suction cup 6, and the setting of the auxiliary component 7 can cooperate with the electromagnetic suction cup 6 to strengthen the adsorption and fixing effect of the wavy guardrail board. During the installation process, the turntable 4 is driven to rotate by starting the motor 41 to achieve the effect of adjusting the angle of the guardrail board, so as to adjust the position of the guardrail board for installation, and the setting of the mobile cart 1 can move the installation position of the highway guardrail board, which effectively improves the installation efficiency of the highway guardrail board.
