Energy-storage type construction hoist

Abstract

The embodiment of the invention discloses an energy-storage type construction hoist, comprising a power grid, a charger, a super capacitor device, a direct current converter, a motor, a frequency changer and a band-type brake, wherein the powder grid is used for communicating a power generation facility with a power utilization facility; the charger is electrically connected with the power grid; the super capacitor device is electrically connected with the charger, and comprises a super capacitor and a battery pack; the direct current converter is electrically connected with the super capacitor device, and further is electrically connected with an electric control element; the motor is electrically connected with the electric control element; the frequency changer and the hand-type brake are connected with the motor; and the super capacitor device is externally connected with an alarm. With the adoption of the energy-storage type building hoist provided by the invention, the mounting labor intensity can be reduced, the safety risk is reduced, the working efficiency and the usability of the construction hoist are improved, and the energy source is saved.

Description

technical field [0001] The invention relates to the technical field of construction elevators, in particular to an energy storage type construction elevator. Background technique [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 twi...

[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 view of this phenomenon, an energy-storage construction elevator that does not need power cable drive and can convert the downward potential energy into electric energy is the future development trend.
