箕斗导向装置的设计
中文摘要
JD系列箕斗有钢丝绳与矩形钢两种罐道形式。钢丝绳采用滑套导向管结构。分半衬套用尼龙或黄铜制成,活
动上盖与底座交接,以便衬套磨损后更换。矩形钢罐道采用滚轮罐耳装置结构,三个滚轮装置组成一组,安装
时焊接在箕斗上盖及底架的两端。在支架上装有两组橡胶缓冲垫,用以保证滚轮紧贴罐道运行,减少容器水
平摆动产生的冲击,使运行平稳而无噪音。滚轮罐耳装置的橡胶轮直径有Φ250、Φ300及Φ350三种,本设计
用Φ350滚轮。
不管是钢丝绳箕斗还是刚性罐道箕斗,在两侧中立柱上、下部位均设有四个钢铸罐耳,以便箕斗在装卸时稳
罐,以及提升过卷时能进入楔形罐道。另外,采用滚轮罐耳装置的箕斗,还必需增设辅助钢罐耳作为安全保
护之用,该罐耳在正常运行中与刚性罐道是不接触的。

Design of Oriented Device of the Skip
ABSTRACT
A series of JD skip have two can road forms-rectangular steel and wire rope. wire rope
structure uses oriented device. And the half hub is made of nylon or brass , base and active
superstructure are handover, it is convenient to replace the worn hub. Rectangular-steel can
road uses wheel structure, the three wheels compose of a group and weld on the two ends of the
superstructure and chassis at the time of the installation. Two sets of rubber cushion equipped
on the hold ensure that the wheels close run on the can road and reduce the impact caused by
the level swing of the container, so that get a smooth operation without the noise.The rubber
wheels have three diameters Φ250, Φ300 and Φ350.The design utilizes Φ350 wheel.
Whether the skip is wire rope or rigid tank road,the middle columns are installed four steel
tank ears on the both sides of the upper and lower parts, in order to the skip work stably on
loading and unloading, and on the out volume it can enter into the wedge-shaped can road. In
addition, the use of the wheel devices, the skip is necessarily increased auxiliary steel ears
as the safe protection, which do not contact with rigid road on the normal operation.
