A trolley line energy storage type construction elevator

Abstract

A trolley conductor energy storage type construction elevator comprises a power grid, a charger, trolley conductors, a battery pack unit, a direct current converter, an electric control component, a motor, an inverter and a brake, the charger is electrically connected with the power grid, the trolley conductors are electrically connected with the charger, the battery pack unit is electrically connected with the trolley conductors through a brush, the direct current converter is electrically connected with the battery pack unit, the electric control component is electrically connected with the direct current converter, the motor is connected with the electric control component, and the inverter is electrically connected with the motor. When power is on, the trolley conductors are connected with the power grid to drive the construction elevator and charge the battery pack unit; when power is off, the battery pack unit is utilized to drive the construction elevator; the installation of power cables, cable trolleys and cable protectors is reduced, so that the intensity of installation is decreased; meanwhile, the shutdown of the construction elevator as the result of the breakage of the conductors of power cables and the outage of a power station is prevented, consequently, safety risk is decreased, and the production efficiency and usability of the construction elevator are increased; and meanwhile, when the construction elevator goes down, the redundant energy generated by the regenerative braking of the motor can be converted into electricity which can charge the battery pack unit.

Description

Technical field [0001] The invention relates to the technical field of construction elevators, in particular to a sliding contact line energy storage type construction elevator. Background technique [0002] At present, the driving method of the construction hoist is driven by a follow-up cable connected to the power grid. The length and quality of the cable are determined by the height of the construction hoist, and when the height of the construction hoist reaches a certain range, it is required The installation process of the cable trolley and cable protection frame is very cumbersome. When the construction hoist is installed to a certain height, the cable is prone to breakage of rubber and copper wire, and when the installation height of the construction hoist reaches 300 meters or more, the cable diameter increases and the weight The increase affects the load capacity of the construction elevator, and the cable twists or the core is often broken during the driving process, w...

Problems solved by technology

[0002] At present, the driving mode of the construction elevator is driven by connecting a follow-up cable to the power grid. The length and quality of the cable are determined according to the stroke height of the construction elevator, and when the stroke height of the construction elevator reaches a certain range, it needs The installation process of cable trolley and cable protection frame is very cumbersome. When the installation height of the construction elevator reaches a certain height, the cable is prone to breakage of rubber and copper wires, and when the installation height of the construction elevator reaches more than 300 meters, the diameter of the cable increases and the weight The increase will affect the load capacity of the construction elevator, and the cables will often be twisted or broken during the driving process, which will increase the safety risk of the operation and construction. When the construction elevator goes down, the motor needs to be generated In addition, in the event of a power outage, the construction elevator can only lower the elevator to the ground by manually releasing the brake, which is not safe and will cause serious damage to the motor brake.
