The New Technology Outlook Of Bridge Grab Unloader

1.High-speed lubricating oil Taking the differential ship unloader, which is the main model with mature technology, as an example, the reducer of the differential ship unloader needs to lubricate the bearings during work, and needs to cool the lubricating oil, so the differential reducer is equipped with an external lubrication cooling system. Through continuous research, the noise and reactive power loss of the reducer are directly related to the amount of lubricating oil in the differential reducer. Developing a high-speed and large-dose lubrication form (such as the form in the metal cutting process), setting it in the differential reducer, greatly reducing the total amount of lubricating oil in the reducer, thereby reducing noise and power consumption, and protecting the environment , Reducing the use cost, will have a positive effect.

2.Use of electronic synchronous shaft In order to ensure the synchronous operation of the two differential reducers and the stable and reliable operation of the trolley, a synchronous shaft system connecting the two differential reducers is arranged on the differential ship unloader. When replacing the wire rope and adjusting the grab, the synchronous shaft needs to be physically disconnected, which increases the technical difficulty and maintenance workload of the site personnel. The electronic synchronous shaft technology has been developed and matured, and the electronic synchronous shaft replaces the mechanical synchronous shaft, which will greatly reduce the maintenance work intensity of the site personnel.

3.Automation function With the development of information technology and communication technology, the automation function of the ship unloader has more fulfilling conditions. As the basic technology for the development of intelligent port terminals, the single-machine automation technology has been tested on the terminal, and it is believed that there will be great progress soon. The automation function has great practical significance for reducing occupational diseases, reducing safety accidents, improving work efficiency, and advancing port terminals towards automation and intelligence.

 

4.Development of dust removal system The differential ship unloader works stably and reliably, and the efficiency can meet the design requirements. Therefore, it has developed rapidly in a short period of time. Today, when the country puts forward higher requirements for environmental protection, the dust pollution to the air and environment during the operation process has become a prominent problem faced by this type of ship unloader. Reducing dust pollution during the operation process is a great technical challenge for open ship unloading equipment. The progress of the dust removal system will have an impact on the development of the mechanical differential ship unloader to a certain extent.
