          挖掘機的用途及功能介紹

          日期:2023-11-28   來源:http://www.thesonriseranchgallery.com/

          挖掘機的應用范圍十分廣泛,通過換裝不同的附屬裝置,如液壓錘、液壓剪、推土鏟、扒斗等可以完成破碎、拆卸、抓取等多種作業。

          The application range of excavators is very wide, and various operations such as crushing, dismantling, and grabbing can be completed by replacing different auxiliary devices, such as hydraulic hammers, hydraulic shears, bulldozers, and buckets.

          1.反鏟作業

          1. Backhoe operation

          反鏟作業一般在地面以下進行,主要以挖掘為主。(1)使用斗桿和鏟斗共同進行挖掘。當鏟斗液壓缸與連桿、斗桿液壓缸與斗桿都成90°角時,可獲得大的挖掘力和挖掘效率。(2)盡量使斗齒方向與挖掘方向保持一致,減少挖掘阻力和斗齒磨損量。

          Backhoe operations are generally carried out below the ground, mainly through excavation. (1) Use the stick and bucket together for excavation. When the hydraulic cylinder of the bucket is at a 90 ° angle to the connecting rod and the hydraulic cylinder of the stick is at a 90 ° angle to the stick, a large digging force and efficiency can be achieved. (2) Try to keep the direction of the bucket teeth consistent with the excavation direction, reducing excavation resistance and bucket tooth wear.

          2.正鏟作業

          2. Shovel operation

          正鏟作業一般在地面以上進行,鏟斗的轉動方式與反鏟時相反。使用斗桿液壓缸來刮削地面。正鏟時的挖掘力小于反鏟時的挖掘力。

          The shovel operation is generally carried out above the ground, and the rotation of the bucket is opposite to that of a backhoe. Use a stick hydraulic cylinder to scrape the ground. The excavation force during the front shovel is smaller than that during the back shovel.

          3.挖溝作業

          3. Trenching operations

          通過配置與溝的寬度相對應的鏟斗,使兩側履帶與要挖溝的邊線平行,可地進行挖溝作業。挖寬溝時,先挖兩側,后挖去中間部分。

          By configuring buckets corresponding to the width of the ditch, the tracks on both sides can be parallel to the edge of the ditch to be excavated, allowing for trench excavation operations. When digging a wide ditch, first dig both sides and then remove the middle part.

          挖掘機橡膠履帶的特點橡膠履帶具有質量輕、振動小、噪聲低、附著力大、地面適應性好、不損壞路面等特點;尤其適合在城市道路施工。

          The characteristics of rubber tracks in excavators include light weight, low vibration, low noise, strong adhesion, good ground adaptability, and no damage to the road surface; Especially suitable for urban road construction.

          橡膠履帶和鋼履帶的基本結構是一樣的,通常也由導向輪、托輪、驅動輪、支匿輪、履帶和行走架等部分組成,其主要區別和特點是:

          The basic structure of rubber tracks and steel tracks is the same, usually composed of guide wheels, support wheels, drive wheels, support wheels, tracks, and walking frames. The main differences and characteristics are:

          (1)橡膠履帶是用橡膠模壓而成的整條連續履帶,心部用織物和多條鋼絲繩加強,外側有履刺,內側有傳動件。鋼制的傳動件鑲嵌在硫化橡膠帶里。橡膠履帶的主要參數是節距、節數、履帶寬度、花紋樣式、預埋金屬件樣式等。

          (1) Rubber track is a continuous track made of rubber molding, reinforced with fabric and multiple steel wire ropes at the center, with spikes on the outer side and transmission components on the inner side. Steel transmission components are embedded in vulcanized rubber belts. The main parameters of rubber tracks are pitch, number of sections, track width, pattern style, and embedded metal part style.

          (2)驅動輪安裝在行走減速器上,用來卷繞履帶,以增加械行駛作業。橡膠履帶用的驅動輪采用凸齒齒形,節距為128mm。履帶工作過程中有彎曲應力,會引起履疲勞損壞,故驅動輪徑不易過小。

          (2) The driving wheel is installed on the walking reducer to coil the track and increase the operation of the machinery. The driving wheel used for rubber tracks adopts a convex tooth profile with a pitch of 128mm. During the operation of the track, there is bending stress, which can cause fatigue damage to the track, so the driving wheel diameter is not easily too small.

          (3)支重輪、托輪和導向輪分跨在履帶齒的兩邊,壓在橡膠平面上,為防止輪緣切割和嚴重擠壓橡膠而損傷,故輪緣較寬,由于履齒較高,故輪體較大。

          (3) The supporting wheels, supporting wheels, and guide wheels are separated on both sides of the track teeth and pressed against the rubber surface. To prevent damage caused by cutting and severe compression of the rubber on the wheel flange, the wheel flange is wider. Due to the higher tread teeth, the wheel body is larger.
