[0038] S1: Construction personnel enter the site, carry out personnel allocation and construction training, prepare and check safety equipment, and the boom lift aerial work platform enters the site for commissioning;

[0039] S2: Install the bracket in the working platform, wrap the bracket with ropes to prevent deformation caused by squeezing between the material and the bracket, and take anti-slip measures. Then adjust the position of the lifting aerial work platform. The position should be convenient for construction workers to plug and install the material with the trestle steel structure. After adjustment, move the material to the working platform of the articulated boom lifting aerial work platform, and take measures to prevent the material from falling during the ascent;

[0040] S3: Construction workers entering the operating platform must wear safety helmets, safety ropes and other safety equipment and take safety precautions for aerial work;

[0041] S4: The construction workers make fine adjustments to the position of the outer guard plate, and complete the alignment and plugging under the steel structure. After the plugging is completed, one person on the construction platform is responsible for supporting the plate, and two people use rivets to fix the outer guard plate. The rivet fixing position needs to be controlled with a line to ensure that the fixing points are on the same horizontal line;

[0042] S5: The workers lower the operating platform through the operating platform. Safety precautions are still required during the descent process until the operating platform is lowered to the ground for the next round of construction. The above steps are repeated until the installation of the outer guard plate is completed;

[0043] The articulated boom lift aerial work platform integrates vertical transportation, operating platform and construction platform, and adopts a multi-stage folding arm combination. The maximum lifting height of the ordinary type can reach 26.5 meters, the rated load capacity is 454kg, and the whole vehicle can rotate 360° continuously and work at any angle.

When constructing the outer guard plate of a coal transport trestle of general height, the entire outer guard plate can be fixed on the work platform. The lifting height and position are controlled by the construction personnel in the work platform. The platform's rising process is more stable, the material transportation precision is high, and the position is easy to adjust, which provides great convenience for the overlap installation of the outer guard plate and improves the construction efficiency. At the same time, it can carry three construction personnel to lift them to the work site at the same time for docking and assembly. After the single piece is assembled, it is lowered to the ground for re-loading, lifting, and assembly, and the process is repeated. The construction personnel are equipped as shown in the following table:

[0051] The working platform has a large area and is equipped with anti-extrusion devices, which ensures the safety of construction workers. The bracket is installed in the platform and wrapped with ropes. On the one hand, anti-slip measures are taken to prevent materials from accidentally falling and causing damage and safety problems. On the other hand, the materials and brackets are prevented from being squeezed and deformed. The transportation, alignment, overlap and installation are completed under the steel structure. During the process, it will not be staggered with the trestle steel structure. The appearance quality of the outer guard plate construction is easy to control. After the construction is completed, the surface cleaning of the outer guard plate and other finished product protection measures also provide great convenience. Under the same conditions, the construction effects of this construction method and the traditional construction method are as follows:

[0052]

[0053] To sum up, compared with traditional construction, the use of lifting aerial work platforms for construction reduces the occupancy of construction sites, reduces material loss, reduces the use of construction machinery, has strong flexibility, high fault tolerance, and greatly improves construction efficiency. At the same time, it guarantees the safety of construction workers to a greater extent, and the quality of exterior guard plate construction results is better, truly achieving the effect of efficient construction.
