如何甑别挖掘机加长臂的优劣?

日期:2019-01-17   来源:http://www.dyqicheng.com/
  我国挖掘机的发展起步于20世纪70年代后期,国内生产挖掘机加长臂的厂家从无到有,先后全国兴起了100多家大大小小的挖掘机加长臂生产厂家,产量每年以上百套的速度推向市场。虽然市场发展形势良好,但由于政府对挖掘机加长臂非标件的生产监管制度还不完善,部份制造商仿制拼装、粗制滥造,所以造成了挖掘机加长臂市场鱼龙混杂的局面。本文笔者根据多年的从业经验就如何甑别挖掘机加长臂的优劣,从哪些方面考察才能选购到质优价廉、服务卓越的挖掘机加长臂,提出几点建议,供大家探讨。
  The development of excavators in our country started in the late 1970s. Domestic manufacturers of excavators'elongated arms have emerged from scratch. More than 100 manufacturers of excavators' elongated arms, large and small, have sprung up all over the country, and the output of more than 100 sets of excavators has been pushed to the market every year. Although the market is developing well, due to the imperfection of the government's supervision system on the production of non-standard parts for excavator elongated arms, some manufacturers imitate and assemble, rough manufacturing, which results in a mixed situation in the market of excavator elongated arms. Based on many years'experience, the author puts forward some suggestions on how to distinguish the advantages and disadvantages of the lengthened arm of the excavator, and from what aspects can we select and purchase the lengthened arm of the excavator with high quality, low price and excellent service for discussion.
  1、挖掘机加长臂的特点:
  1. The characteristics of the lengthened arm of excavator:
  加长臂挖掘机,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。
  An extended arm excavator is installed between the body bracket and the working arm. The extended arm is supported and connected by the crude oil cylinder. A working arm cylinder and the excavator cylinder are installed on the extended arm. A set of cylinder control system is installed inside and outside the cab to coordinate the telescopic operation of the working arm cylinder and the excavator cylinder so as to enable the excavator to move. It is a breakthrough transformation of excavating machinery and has great practical value. It is more than twice the scope and reaches a higher, deeper and farther scope. It is especially suitable for mining, wharf, warehousing, flood fighting and emergency operations and special occasions.
  2、挖掘机加长臂的组成结构:
  2. The structure of the excavator's elongated arm:
  加长臂挖掘机,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:在车体支架上端配合连接一个加长臂,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配合连接。
  The elongated arm excavator is composed of working arm, elongated arm, crude oil cylinder, working arm cylinder, excavator bucket cylinder, etc. Its characteristics are that an elongated arm is connected with the upper end of the body bracket, the lower side of the elongated arm is connected with the original cylinder, the front end of the elongated arm is connected with one end of the working arm through a pin shaft, and a working arm cylinder is installed between the working arm and the elongated arm. There is a excavator bucket at the front end of the working arm. One side of the excavator bucket is connected with one end of the excavator bucket cylinder through a connecting rod, and the other end of the excavator bucket cylinder is connected with the elongated arm through a pin shaft.

  3、挖掘机加长臂在施工中有以下的特点:
  3. Excavator elongated arm has the following characteristics in construction:
  (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, less labor, simple construction organization, high construction efficiency and rapid progress of the project;
  (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 lengthened arm has stricter requirements on excavator quality. It can also be said that the arm is a test of excavator quality. It is not easy to segregate in the course of action, so it is easy to ensure the quality of the project.
  (3)作业安全,可减少施工过程中的危险;
  (3) Safety of operation can reduce the danger in 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) It has strong adaptability to construction work and wide scope of work. The excavator's elongated arm can be laid to other difficult places to meet various construction requirements.
  (5)在正常工作条件下,挖掘机加长臂不会污染环境,符合环保要求。
  (5) Under normal working conditions, the longer arm of excavator will not pollute the environment and meet the requirements of environmental protection.
