[0015] Based on the above-mentioned mechanical equipment for installing corrugated guardrails, the top of the lifting bracket is a cross-X-shaped structure, and a lifting rail fixing body is provided at the intersection, and two cross beams are arranged at intervals on the lifting bracket.

[0016] Based on the above-mentioned mechanical equipment for installing the corrugated guardrail, the vehicle side distance detection device includes a fixing rod and a distance measuring rod arranged on the fixing rod.

[0017] A method for installing a corrugated guardrail using mechanical equipment includes the following steps:

[0018] Use a forklift or lifting equipment to load the entire corrugated guardrail onto the vehicle body. After loading, the corrugated guardrail installation mechanical equipment moves along the installation direction of the guardrail column on the road side of the corrugated guardrail installation location, while the vehicle body and the installation location maintain a parallel distance of about 1 meter. When the vehicle body reaches the corrugated guardrail installation location, it stops moving forward. The electric hoist (7) moves to the top of the guardrail, uses the lifting device to fix the side of the guardrail, lifts it, and moves it horizontally to the top of the installation location. The height of the guardrail is adjusted to the installation location. The rear end of the guardrail is installed with fixing bolts and fixed to the guardrail fixing frame. The lifting device is released and the vehicle moves to the position where the next guardrail is to be lifted. A support frame is placed at the bottom of the front end lifting point of the guardrail to support the guardrail. The hook can be removed and the vehicle moves to the position where the next guardrail is to be lifted.

[0019] The corrugated guardrail installation machinery equipment automatically stops after traveling parallel to the installation route for a standard installation distance according to the vehicle side distance detection device, and the workers hoist the guardrail board and proceed to the next repetitive process;

[0020] When it is necessary to install the guardrail on the other side of the same lane, drive the corrugated guardrail installation mechanical equipment to the installation position, rotate the electric hoist track 180 degrees, and rotate the cantilever end to the top of the guardrail installation position for installation;

[0021] When the mechanical equipment for installing the corrugated guardrail returns to the base, the electric hoist track should be retracted and fixed to prevent it from scratching objects.

[0022] The advantages of the present invention are:

[0023] It integrates the functions of transportation, hoisting, fast installation, and automatic movement to the next workstation. The whole process does not require human intervention. All work can be completed with the assistance of the installer and the installation of bolts. This not only reduces the number of workers, increases the installation speed, but also greatly reduces the labor intensity, providing strong support for the realization of automated construction.
