挖掘机伸缩臂是装在挖掘机大臂上的一种格外变乱装置;用于机动扩展其作业半径以及垂直深挖范围。伸缩臂挖机租赁职员是怎样对其举行分类呢?
  The telescopic arm of excavator is a special working device mounted on the arm of excavator, which is used to flexibly expand its operating radius and vertical deep excavation range. How does the telescopic boom excavator renter classify it?
  一:伸缩臂挖掘机分类
  Classification of telescopic boom excavators
  按其布局外型可分为:外伸缩和内伸缩; 外伸缩是颠末伸缩缸及滑块的作用使移动体在壮实体上方使其冷静伸缩。内伸缩是移动体套入壮实体内,颠末伸缩缸的伸缩使移动体伸出及缩回
  According to its structure appearance, it can be divided into: outward expansion and inward expansion; outward expansion makes the mobile body free expansion above the fixed body through the action of the expansion cylinder and slider. Internal telescoping is that the mobile body is inserted into the fixed body, and the mobile body is extended and retracted by the telescoping cylinder.
  按其变乱原理可分为:序次伸缩和同步伸缩。序次伸缩采取多级缸或多个单级缸等要领直接用油缸推进;同步伸缩采取单缸加钢丝绳、滑轮组件完成伸缩。
  According to its working principle, it can be divided into sequential expansion and synchronous expansion. Sequential expansion is driven by multi-stage cylinder or single-stage cylinder directly, and synchronous expansion is realized by single cylinder plus wire rope and pulley assembly.
  二:伸缩臂挖掘机特性
  2. Characteristic of telescopic boom excavator
  外伸缩臂其特性紧张在于:
  The characteristics of the telescopic arm mainly lie in:
  1、外伸缩臂由上滑动臂与下壮实臂两局部构成,上滑动臂陈设在下壮实臂上方,颠末两侧滚轮及道轨上下构成活动体,颠末伸缩缸的伸缩来推进上滑动体前后冷静伸缩。
  1. External telescopic arm is composed of upper sliding arm and lower fixing arm. The upper sliding arm is installed above the lower fixing arm. The upper sliding arm is composed of movable body through two rollers and rails. The upper sliding body can be freely telescoped by telescopic cylinder.
  2、上滑动臂内装伸缩缸,伸缩缸的缸体壮着实下壮实臂上,伸缩缸活塞杆壮着实上滑动臂上。其紧张部件有:壮实体、移动体、滑块、伸缩缸等。外伸缩臂具有受力大、布局约莫,可以大约冷静调停变乱半径、调停挖掘深度,易于应用,顺应特定环境作业。但其行程较小,一样伟大其行程在4米内。
  2. The upper sliding arm is equipped with a telescopic cylinder. The cylinder block of the telescopic cylinder is fixed on the lower fixed arm, and the piston rod of the telescopic cylinder is fixed on the upper sliding arm. Its main components are: fixed body, mobile body, slider, telescopic cylinder, etc. External telescopic arm has large force, simple structure, can adjust the working radius freely, adjust the depth of excavation, easy to operate and adapt to specific environment. But its journey is small, usually within 4 meters.

  内伸缩臂其特性紧张在于:
  The inner telescopic arm is characterized by:
  1、 内伸缩臂是由移动体套入壮实体内,颠末伸缩缸的伸缩使移动体伸出及缩回,从而抵达冷静伸缩的目的;
  1. The internal telescopic arm is inserted into the fixed body by a mobile body, and the mobile body extends and retracts through the expansion of the telescopic cylinder, thus achieving the purpose of free telescoping.
  2、 其布局只需一个壮实体和一个或多个移动体,节为壮实体,别的的是移动体,移动体按其大小先后序次套入壮实体内,原理是二节套入一节、三节套入二节….,颠末伸缩缸使其有序次伸出或缩回;内伸缩臂其布局较庞大、斲丧资源较高,一样伟大设计成两节以上,用于深坑作业的抓取与扬土。其益处是增大了作业半径以及挖掘深度。
  2. Its structure has only one fixed body and one or more mobile bodies. The first section is fixed body, the rest are mobile body. The mobile body is inserted into the fixed body in order of its size. The principle is that two sections are inserted into one section and three sections are inserted into two sections. The inner telescopic arm has complex structure and high production cost. It is generally designed to be more than two sections for grasping and lifting soil in deep pit operation. Its advantage is to increase the working radius and excavation depth.
  挖掘机伸缩臂运用范围:均运用于受变乱半径以及深挖范围限定的格外作业环境,可以机动的增减其作业半径与挖掘深度范围,有效的提高变乱遵从。
  Excavator telescopic boom application field: all of them are applied in special working environment limited by working radius and deep excavation range, which can flexibly increase and decrease its working radius and excavation depth range, and effectively improve work efficiency.
