          反鏟式挖掘機的使用優勢有哪些?

          日期:2023-12-14   來源:http://www.scypxchina.com/

          反鏟式挖掘機是我們常見的挖土設備的一種挖掘機,主要用于作業面以下的基坑(槽)或管溝、獨立基坑及邊坡的開挖;直線、曲線挖掘、保持一定角度挖掘、超深溝挖掘和溝坡挖掘等。

          Backhoe excavator is a type of excavator commonly used in excavation equipment, mainly used for excavation of foundation pits (trenches) or pipe trenches below the working surface, independent foundation pits, and slopes; Straight line and curve excavation, excavation at a certain angle, ultra deep trench excavation and slope excavation, etc.

          反鏟挖掘機用為廣泛的土方挖掘機械,具有操作靈活、回轉速度快等特點。近年來反鏟挖掘機市場飛速發展,挖掘機的生產向大型化、微型化、多功能化、專用化的方向發展?;油练介_挖可根據實際需要,選擇普通挖掘深度的挖掘機,也可以選擇較大挖掘深度的接長臂、加長臂或伸縮臂挖掘機等。反鏟挖掘機的主要參數有整機質量、外形尺寸、標準斗容量、行走速度、回轉速度、大挖掘半徑、大挖掘深度、大挖掘高度、大卸載高度、小回轉半徑、尾部回轉半徑等。

          Backhoe excavators are widely used as earth excavation machinery, with characteristics such as flexible operation and fast rotation speed. In recent years, the backhoe excavator market has developed rapidly, and the production of excavators has shifted towards large-scale, miniaturized, multifunctional, and specialized directions. Excavation of foundation pit soil can be carried out by selecting excavators with ordinary excavation depths according to actual needs, or by selecting excavators with extended arms, extended arms, or telescopic arms with larger excavation depths. The main parameters of a backhoe excavator include overall weight, external dimensions, standard bucket capacity, walking speed, rotation speed, large excavation radius, large excavation depth, large excavation height, large unloading height, small rotation radius, and tail rotation radius.

          反鏟挖掘機的選型應根據基坑土質條件、平面形狀、開挖深度、挖土方法、施工進度等情況,結合挖掘機作業方法等進行選型;在實際應用中,應根據生產廠家挖掘機產品的規格型號和技術參數,并結合施工單位的施工經驗進行選型。

          The selection of backhoe excavators should be based on the soil conditions of the foundation pit, plane shape, excavation depth, excavation method, construction progress, and other factors, combined with the excavator operation method; In practical applications, the selection should be based on the specifications and technical parameters of the excavator products produced by the manufacturer, and combined with the construction experience of the construction unit.

          反鏟裝置是中小型液壓挖掘機的主要工作裝置,也是工程施工中運用廣泛的工作裝置。反鏟作業主要用于挖掘機停機面以下的土壤,故大挖掘深度和大挖掘半徑是反鏟挖掘的主要作業參數。

          The backhoe device is the main working device of small and medium-sized hydraulic excavators, and it is also a widely used working device in engineering construction. Backhoe operation is mainly used for the soil below the excavator stop surface, so large excavation depth and large excavation radius are the main operating parameters of backhoe excavation.

          反鏟液壓挖掘機的工作裝置由反鏟鏟斗、鏟斗油缸、斗桿、斗桿油缸、動臂、動臂油缸、連桿機構等構成,各部件間全部采用鉸接,通過油缸的伸縮來實現挖掘過程中的各種動作。動臂趾部與動臂油缸下支點均鉸接在轉臺上,并以動臂油缸來支承和改變動臂的傾角,通過動臂油缸的伸縮可使動臂繞下鉸點轉動而升降。斗桿鉸于動臂的上端,斗桿與動臂的相對位置由斗桿油缸控制,動臂升降靠動臂油缸控制,鏟斗相對于斗桿的轉動靠鏟斗油缸控制。用反鏟作業時,可根據需要在放下動臂的同時轉動斗桿或鏟斗;卸料時,也可同時轉動斗桿或鏟斗。轉動鏟斗可將料直接卸于運輸車上。

          The working device of a backhoe hydraulic excavator consists of a backhoe bucket, bucket oil cylinder, stick, stick oil cylinder, boom, boom oil cylinder, connecting rod mechanism, etc. All components are hinged, and various actions during the excavation process are achieved through the extension and contraction of the oil cylinder. The toe of the boom and the lower fulcrum of the boom cylinder are hinged on the turntable, and the boom cylinder is used to support and change the tilt angle of the boom. The boom can rotate around the lower hinge point and rise and fall through the extension and contraction of the boom cylinder. The stick is hinged on the upper end of the boom, and the relative position between the stick and the boom is controlled by the stick oil cylinder. The boom lifting is controlled by the boom oil cylinder, and the rotation of the bucket relative to the stick is controlled by the bucket oil cylinder. When working with a backhoe, the boom can be lowered while rotating the stick or bucket as needed; When unloading, the bucket handle or bucket can also be rotated simultaneously. Rotating the bucket can directly unload the material onto the transport vehicle.

          為了增加Cat卡特鏟斗轉角,鏟斗油缸往往通過連桿機構與鏟斗相連。動臂、斗桿、鏟斗的動作可分別進行,也可同時進行。挖掘時動作靈活,效率較高。

          In order to increase the angle of the Cat Cat Cat bucket, the bucket cylinder is often connected to the bucket through a linkage mechanism. The actions of the boom, stick, and bucket can be performed separately or simultaneously. Flexible movements and high efficiency during excavation.

          動臂是工作裝置的主要構件,斗桿的結構一般取決于動臂的結構。反鏟動臂有直動臂和彎動臂兩種直動臂構造簡單、輕巧、布置緊湊,主要用于懸掛式挖掘機。

          The boom is the main component of the working device, and the structure of the stick generally depends on the structure of the boom. There are two types of backhoe boom: straight boom and curved boom. The straight boom has a simple, lightweight, and compact layout, and is mainly used in suspended excavators.
