High-altitude operation platform based on PLC control and use method thereof

Abstract

The invention discloses a high-altitude operation platform based on PLC control, and relates to the technical field of cable line inspection and maintenance operation platforms. The high-altitude operation platform based on PLC control comprises a baseplate, a supporting rod group, a lead screw, power modules, a control device, front and rear slide base, a PLC and slide rails. The power modules include the PLC, a gear resistor, a small power supply, a lighting resistor, a deceleration motor, a power switch, a gear switch, a sudden stop relay, a pressure relay and a distance relay. The input end COM interface of the PLC is connected with the power switch circuit. The output end COM interface of the PLC is connected with the switch interface circuit of the sudden stop relay. The supporting rod group includes supporting rods and synchronization rods. PLC control is adopted, and the operation platform is stable in elevating, high in control precision and safe to use; the elevating distance of the platform is automatically measured, and the power supply of a speed reducer can be automatically cut off when the highest safety height is exceeded so that danger can be avoided; and the pressure relay is adopted to sense existence of operators on the floor of the platform so that misoperation can be avoided.

Description

technical field [0001] The invention relates to a lifting platform, in particular to a lifting platform suitable for electric power maintenance, and belongs to the technical field of electric power maintenance. Background technique [0002] When working on high maintenance points in the power industry, the traditional way is to use ladders to climb up or use foot buckles to climb utility poles. When using a ladder, another person needs to hold the ladder, which is not only inconvenient, but also not safe. , The space on the ladder is also limited, generally only one person can operate. Distribution overhead lines are prone to failures in rainy days, affecting users' daily power consumption and need to be repaired in time. In rainy days, utility poles are relatively slippery, and it is difficult for maintenance personnel to buckle them up with their feet. The maintenance personnel are sent up by a lifting platform; however, the stability of the existing lifting platforms nee...

[0002] When working on high maintenance points in the power industry, the traditional way is to use ladders to climb up or use foot buckles to climb utility poles. When using a ladder, another person needs to hold the ladder, which is not only inconvenient, but also not safe. , the space on the ladder is also limited, generally only one person can operate

Distribution overhead lines are prone to failures in rainy days, affecting the daily power consumption of users, and need to be repaired in time. In rainy days, the utility poles are relatively slippery, and it is difficult for maintenance personnel to buckle on them with their feet. Therefore, power maintenance in many places now takes more The maintenance personnel are sent up by a lifting platform; however, the stability of the existing lifting platforms needs to be improved, and the degree of automation and intelligence of the existing lifting platforms is not high; most of the lifting platforms in the prior art use scissor lifts The scissor arm of the device is generally fixed at one end, and the other end slides to the middle for lifting. This structure will cause the center of gravity of the platform to deviate from the center. Due to the offset of the center of gravity, there is a safety hazard of overturning when the lifting height is high
