A two-degree-of-freedom NC Scissor-fork cantilever mechanism for bucket wheel machine is a planar two-degree-of-freedom reverse five-bar mechanism with moving pairs. Under the control of computer programming, the driving rod and slider drive the cantilever pitching movement together, and then complete the two-degree-of-freedom excavation operation. This kind of Scissor-fork cantilever mechanism has compact structure, high flexibility and large motion space, which effectively guarantees the operation of bucket wheel machine. Space and reachable operating range. The shearing fork type cantilever mechanism replaces the existing hydraulic transmission of the cantilever mechanism of bucket wheel machine by connecting rod transmission, avoids the problems of high energy consumption and high maintenance cost of the hydraulic bucket wheel machine, and has the advantages of low energy consumption and high reliability. The cantilever mechanism adopts the shearing fork type design, which is not only compact in structure, but also highly flexible. It is especially suitable for manufacturing small bucket wheel machine and meets the narrow empty space. During this period, bulk bulk materials were stacked continuously and ditches were excavated.

一种斗轮机用两自由度数控剪叉式悬臂机构
本专利技术涉及臂架型斗轮机领域,特别是一种斗轮机用两自由度数控剪叉式悬臂机构。
技术介绍
斗轮机又叫斗轮堆取料机,是现代化工业大宗散状物料连续装卸的高效设备,广泛应用于港口、码头、冶金、水泥、储煤场等散料的存储料场,进行大量矿石、煤、焦炭等散料的堆料、取料作业。斗轮机连续作业效率高,并且具有很强的规律性,因此从控制角度可分为手动、半自动和自动化控制。虽然斗轮机在工程作业中得到了广泛应用,但也存在诸多技术问题。首先,现有臂架式斗轮机悬臂的俯仰运动主要有两种方式,一种是纯机械臂架式斗轮机,其悬臂通过钢丝绳卷扬机构实现俯仰运动,该种类型的斗轮机虽具有较高的可靠性以及传动效率,但灵活性差;另一种是液压结构的臂架式斗轮机,其悬臂通过液压缸实现俯仰运动,该种类型的斗轮机虽灵活性好,但可靠性差、机械效率低、能耗高,液压系统易发生漏油等问题,维护保养及使用成本高。其次,现有臂架式斗轮机结构复杂,体积巨大,灵活性差,无法应用于空间狭小的室内工厂,也无法适用于小型沟渠等开挖作业,以及铺设农田水利灌溉地下管道、安装自来水管道、铺设电缆以及开挖矩形 ...
