带斗门座起重机移动卸料漏斗的优化

Optimization of mobile discharge hopper with portal crane with bucket

在散货设备中,卸料系统的简化设计有着巨大的优化空间,带斗门座起重机是一种常见的散货卸料设备,常规带斗门座起重机卸料漏斗前后移动时,需要安装在防止漏斗倾覆的支撑梁结构上,导致整机结构质量大,增大了对码头的载荷;支撑梁安装尺寸大,影响码头现场作业范围;整机安装复杂,安装周期长,成本居高不下;设计形式繁琐,后期维修保养工作量大、成本高。文中通过对卸料系统漏斗外形的变化以及异形漏斗结构的校核,确定了异形漏斗的设计的方案,补偿了部分漏斗前后移动的距离,从而优化了前后伸缩移动的结构形式,前后伸缩驱动机构的计算优化,取消了常规漏斗的伸缩支撑梁。给出修改后的卸料漏斗安装方案,大大降低了安装成本和安装周期。采用此移动卸料漏斗的带斗门座起重机具有自重轻、安装方便、维护保养工作量少等优点。

In bulk cargo equipment,the simplified design of the unloading system has much room for optimization.The portal crane with bucket is a common bulk cargo unloading equipment.When the unloading funnel of the conventional portal crane with bucket moves back and forth,it needs to be installed on the supporting beam structure to prevent the funnel from overturning,which leads to a large structural mass of the whole machine and increases the load of the wharf.The installation size of supporting beam is large,which affects the on-site operation scope of the wharf.The installation of the whole machine is complicated,the installation lasts long and the cost is high.The design structure is complicated,bringing a increase of later maintenance workload and a high cost.In this paper,the design plan of the special-shaped funnel is determined by reviewing the change of the funnel shape of the discharging system and the structure of the special-shaped funnel,which compensates the distance of some funnels moving back and forth,thus optimizing the structural form of the telescopic movement back and forth.The calculation optimization of the front and rear telescopic driving mechanism cancels the telescopic supporting beam of the conventional funnel.The installation plan of the modified discharge funnel is given,which greatly reduces the installation cost and installation cycle.The portal crane with bucket and this movable discharge hopper has the advantages of light weight,convenient installation and less maintenance workload.
