Description

A kind of rubber tyre gantry crane power-supply system holder

Technical field

The utility model is related to crane power supply technique fields more particularly to a kind of battery-driven rubber tyre gate-type to rise The holder of the power-supply system of heavy-duty machine.

Background technology

Rubber tyre gantry crane (RTG Crane, abbreviation RTG) is a kind of the big of the big object such as transferring containers The gantry crane of type rubber-tyred, is moved by tire, is generally used in logistics circulation, such as on harbour, warehouse or airport Etc. the occasion for needing to carry larger object.

As crane, when being operated to the big object such as container, RTG needs very strong power output, due to RTG It is frequently necessary to carry more than 20 tons of the oversized container of weighing, so its any one action is required for significant energy and work( Rate.Existing RTG typically uses internal combustion engine as power source, is additionally and briefly worked by driven in two modes associated mechanisms：Bavin Oil machine-hydraulic way and the electronic mode of diesel engine-.

Diesel engine-the hydraulic way, i.e., by Diesel Driven hydraulic system, hydraulic pump drives hydraulic motor, then drives Dynamic each mechanism work.Which accelerating ability is good, power plant lighter in weight, but system easy tos produce oil leak, maintenance It is more complex, so using less.

The electronic mode of diesel engine-, i.e., by diesel engine band dynamotor, dc generator drives direct current again Motor drives each organisation operations.In recent years, start using AC variable-frequency speed regulation system, mouse cage AC electric motor-driving way, It is easy to maintain since motor is simple, it is welcome by user.
