长臂挖掘机的组成结构及特点

日期:2023-10-10   来源:http://cnqpzh.com
长臂挖掘机,它是在车体支架及工作臂之间,加装一个加长臂,加长臂由原油缸支撑连接,并在加长臂上加装了一个工作臂油缸及挖掘斗油缸,在驾驶室内外,相应的加装了一套油缸的操纵系统,配合操纵工作臂油缸及挖掘斗油缸的伸缩作业,可使挖掘斗的活动范围扩大一倍以上,达到的范围更高、更深、更远,特别适应矿山、码头、仓储、抗洪抢险及特殊的场合作业,是挖掘机械的一大突破性改造,具有极大的实用价值。
The long arm excavator is equipped with an extended arm between the vehicle support and the working arm. The extended arm is supported and connected by the original oil cylinder, and a working arm oil cylinder and a digging bucket oil cylinder are installed on the extended arm. A set of oil cylinder control system is installed inside and outside the driver's cab to cooperate with the telescopic operation of the working arm oil cylinder and the digging bucket oil cylinder, which can expand the range of movement of the digging bucket by more than twice, achieving a higher range Deeper and farther, especially suitable for mining, docks, warehousing, flood control and emergency operations, and special occasions, it is a major breakthrough transformation of mining machinery and has great practical value.
组成结构
Composition structure
长臂挖掘机,由工作臂、加长臂、原油缸、工作臂油缸、挖掘斗油缸等组成,其特征是:在车体支架上端,动配合的连接一个加长臂,加长臂的下侧面与原油缸相连接,加长臂前端通过销轴与工作臂的一端动配合连接,工作臂与加长臂之间安装一个工作臂油缸。在工作臂的前端有一个挖掘斗,挖掘斗一侧通过连杆与挖掘斗油缸的一端连接,挖掘斗油缸的另一端通过销轴与加长臂动配合连接。
A long arm excavator is composed of a working arm, an extended arm, an original oil cylinder, a working arm oil cylinder, a digging bucket oil cylinder, etc. Its feature is that at the upper end of the vehicle support, an extended arm is dynamically connected, and the lower side of the extended arm is connected to the crude oil cylinder. The front end of the extended arm is dynamically connected to one end of the working arm through a pin, and a working arm oil cylinder is installed between the working arm and the extended arm. At the front end of the working arm, there is a digging bucket. One side of the digging bucket is connected to one end of the digging bucket oil cylinder through a connecting rod, and the other end of the digging bucket oil cylinder is connected to the extended arm through a pin shaft.
长臂挖掘机
挖掘机加长臂在施工中有以下的特点:
The characteristics of excavator extension arm during construction are as follows:
(1)机械化程度高,需要劳动力少,施工组织简单;施工效率高,工程进度快;
(1) High degree of mechanization, requiring less labor, and simple construction organization; High construction efficiency and fast project progress;
(2)加长后的臂对挖掘机质量要求比较严格,也可以说臂是对挖掘机质量的一次检验,在动作过程中不易离析,因此容易保证工程质量;
(2) The extended arm has strict requirements for the quality of the excavator, which can be said to be an inspection of the excavator's quality. It is not easy to separate during operation, so it is easy to ensure the engineering quality;
(3)作业安全,可减少施工过程中的危险;
(3) Job safety can reduce the risks during the construction process;
(4)对施工作业面的适应性强,作业范围广,挖掘机加长臂可以铺设到其他难以到达的地方,满足各种施工要求;
(4) Strong adaptability to construction work surfaces, wide range of operations, excavator extension arms can be laid to other difficult to reach places, meeting various construction requirements;
(5)在正常工作条件下,挖掘机加长臂在不会污染环境,符合要求。
(5) Under normal working conditions, the extension arm of the excavator will not pollute the environment and meets environmental requirements.
