Electric vehicle charging device base gangway and quality control

Abstract

The invention discloses an electric vehicle charging device base gangway. The electric vehicle charging device base gangway comprises a main body unit, an initial prestressed tension adjusting unit, ahighest prestressed tension adjusting unit and a maximum movement range adjusting unit, the main body unit is composed of a gangway hook, a gangway lug, a gangway support and an adjusting screw rod,the initial prestressed tension adjusting unit is composed of elastic force of the prefabricated radian of the gangway hook and the adjusting screw rod, the highest prestressed tension adjusting unitis composed of a gangway lug upper limit point and an adjusting screw rod center line position, and the maximum movement range adjusting unit is composed of a gangway lug starting acting point, a gangway hook starting position and a gangway hook position stopping acting point. According to the electric vehicle charging device base gangway, standard quality control in batch production, installation, debugging and use of a whole gangway part and a part is effectively realized, and prevention and control of loosening and separation of batch bases and a ground are further realized.

Description

technical field [0001] The invention relates to the intersecting fields of new energy vehicles, machinery manufacturing, and electromechanical installation, and in particular relates to bridge crossing and quality control of electric vehicle charging device bases. Background technique [0002] After the electric vehicle charging device is put into use, including the natural wind force for many years, the complex external force of people and objects in the outdoor open environment, the side force and upward pulling force of the charging pole on the ground are transmitted to the underground base and the ground, resulting in the base Loosening or even complete separation from the ground will lead to damage to the underground foundation and the associated buried lines. The repair and reconstruction of the foundation and lines will cost a lot and take a long time. At present, in the design of the bridge bridge in the base of the electric vehicle charging device, there are inventi...

Problems solved by technology

[0002] After the electric vehicle charging device is put into use, including the natural wind force for many years, the complex external force of people and objects in the outdoor open environment, the side force and upward pulling force of the charging pole on the ground are transmitted to the underground base and the ground, resulting in the base Loosening or even complete separation from the ground will lead to damage to the underground base and associated buried lines, and the repair and reconstruction of the base and lines will cost a lot and take a long time

At present, in the design of the bridge bridge in the base of the electric vehicle charging device, there are inventions of technical prevention principles that reflect the loosening and detachment of the base from the ground caused by external forces, but how to make the base bridge have a downward controllable prestressed tension , and let the bridges in the batch foundation have the same amount of downward prestressed tension and maximum failure force, lack of new design and standard quality control, it is further difficult to realize the standard quality control of mass production, installation, commissioning and use of bridge products , and then it is difficult to realize the standardized prevention and control of the loosening and detachment of the base and the ground in batches
