1.物料挖掘类

1. Material excavation

(1)水陆两用挖掘机

(1) Amphibious excavator

水陆两用挖掘机以普通挖掘机上车平台为基础,配备了中空浮箱式底盘,从而使其具有在沼泽、滩涂等松软地面上行走、停驻、作业的能力。此类设备仍以铲斗挖掘物料为主,在河道清淤、湖泊滩涂作业方面适应能力很强。

The amphibious excavator is based on the common excavator loading platform and is equipped with a hollow floating box chassis, which enables it to walk, park and work on soft ground such as marsh and mudflat. This kind of equipment is still mainly used to excavate materials with buckets, and has strong adaptability in river dredging and lake mudflat operations.

(2) Extended arm excavator

普通挖掘机通过更换加长的动臂、斗杆,即成为加长臂型挖掘机。加长臂型挖掘机能实现较大范围的作业,广泛用于河道疏浚、湖泊清洁、水库维护等特殊工况,同时也可用大坡面的修缮工作。加长臂挖掘机用于水下挖掘时,为保证较好的视野,通常在斗杆上配置水下摄像头,以便驾驶员随时掌握铲斗和物料状态。

A regular excavator becomes an extended arm excavator by replacing the extended boom and stick. Extended arm excavators can achieve large-scale operations and are widely used in special working conditions such as river dredging, lake cleaning, and reservoir maintenance. They can also be used for repairing large slopes. When an extended arm excavator is used for underwater excavation, in order to ensure a better field of view, an underwater camera is usually installed on the bucket handle, so that the driver can always grasp the status of the bucket and materials.

水陆两用挖掘机与加长臂通过相互结合,形成优势互补,能够更好地完成滩涂和水下挖掘工作,是大型滩涂作业和维护的必备机械。图1所示为某加长臂水陆两用挖掘机。

The amphibious excavator and the extended arm form complementary advantages by combining each other, which can better complete the mudflat and underwater excavation work. It is a necessary machine for large-scale mudflat operation and maintenance. Figure 1 shows a brand of extended arm amphibious excavator.

2.物料抓取类

2. Material grabbing class

给挖掘机配备抓取类机具,使其具有抓物、抓料等功能,可实现挖掘机功能、用途多样化。此类挖掘机抓斗具有多种动作,为此往往需要在原有液压系统的基础上新增若干路供油和操纵装置。物料抓取类挖掘机的属具主要有4类,分别是抓管器、抓木钳、梅花抓斗和贝壳斗。

Equipping excavators with grabbing tools to have functions such as grabbing objects and materials can achieve diversified functions and uses of excavators. This type of excavator grab has multiple movements, which often requires adding fuel supply and control devices on the existing hydraulic system. There are four main types of material grabbing excavators, namely pipe grabbers, wood grabbing pliers, plum blossom buckets, and shell buckets.

(1)抓管器

(1) Grabber

管道施工不仅要求设备能够抓取管道,还要求其能够灵活控制管道的姿态。通常,抓管器采用液压马达驱动,可实现360°回转,配合挖掘机动臂、斗杆、四连杆机构、上车回转等多个动作,可实现管道5个自由度的精确定位。此类挖掘机广泛应用于石油天然气、石化、冶金、港口疏浚等行业的管线铺设以及管道制品转运等。全回转液压抓管器结构如图2所示。

Pipeline construction not only requires equipment to be able to grasp the pipeline, but also requires it to be able to flexibly control the posture of the pipeline. Usually, the pipe gripper is driven by a hydraulic motor and can achieve 360 ° rotation. When combined with multiple actions such as excavator arm, bucket, four-bar linkage, and upper body rotation, it can achieve precise positioning of the pipeline with 5 degrees of freedom. This type of excavator is widely used in pipeline laying and transportation of pipeline products in industries such as oil and gas, petrochemicals, metallurgy, and port dredging. The structure of the fully rotating hydraulic pipe gripper is shown in Figure 2.

(2)抓木钳

(2) Grabbing wooden pliers

抓木钳又称抓木夹、夹木器,由一组互相交错的叉形钳组成,主要作用为抓取木材或秸秆类物料。通常抓木钳具有俯仰、回转和开合3个动作,可通过调整姿态准确抓取木材或其他物料。抓木钳结构简单,能够替代大量人工搬运和装车,使用方便灵活,极大地提高了作业的效率。

Grasping pliers, also known as grabbing clamps or wooden tools, are composed of a set of interlocking forked pliers, mainly used to grab wood or straw materials. Usually, wood grabbing pliers have three movements: pitch, turn, and open/close, and can accurately grasp wood or other materials by adjusting the posture. The wooden pliers have a simple structure and can replace a large amount of manual handling and loading. They are convenient and flexible to use, greatly improving the efficiency of operations.

(3)梅花抓斗

(3) Plum Blossom Grab

梅花抓斗是一种广泛应用于钢铁厂、冶炼厂、港口、码头和废钢转运等行业的特种属具,如图3所示。配装在挖掘机上的梅花抓斗采用液压缸驱动,常见的斗瓣数为4~6片。在工作时抓斗一般只有开合动作,因此可以采用原挖掘机铲斗缸的油路驱动。将挖掘机改为抓料机对挖掘机的改动较小,便于实现。为了使驾驶员获取很好的视野,确保作业的和效率,一般将其驾驶室设计为增高型。

Plum blossom grab is a special tool widely used in industries such as steel mills, smelters, ports, docks, and scrap steel transportation, as shown in Figure 3. The plum blossom grab bucket installed on the excavator is driven by a hydraulic cylinder, and the most common number of buckets is 4-6 pieces. During operation, the grab bucket usually only has an opening and closing action, so it can be driven by the oil circuit of the original excavator bucket cylinder. Changing the excavator to a grabbing machine requires minimal modifications to the excavator, making it easier to implement. In order to provide drivers with a good view and ensure the safety and efficiency of operations, their cabins are generally designed to be elevated.

(4)贝壳斗

(4) Beike Dou

贝壳斗由于其外形和动作类似贝壳而得名,在斗形闭合时料斗可形成封闭的腔体。贝壳斗主要包含主机架、左斗、右斗和驱动液压缸。贝壳斗类似于梅花抓斗,一般也只有开合动作。贝壳斗容量大但挖掘力小,为此主要用于轻质松散物料的装卸和搬运,如用于港口、码头、煤场的装沙、装煤等。

The shell hopper is named after its shape and action similar to shells, and when the hopper is closed, it can form a closed chamber. The shell bucket mainly includes the main frame, left bucket, right bucket, and driving hydraulic cylinder. Beike Dou is similar to plum blossom grab, usually only having opening and closing movements. The shell hopper has a large capacity but low excavation force, and is mainly used for loading, unloading, and handling of lightweight loose materials, such as loading sand and coal in ports, docks, and coal yards.

3.物料破裂与剪切类

3. Material rupture and shearing

挖掘机通过安装不同属具,不仅可以实现土石方等物料的搬运,还可以用于各种物料破碎、破裂、剪切等。物料破裂类挖掘机的属具主要有3类,分别是破碎锤、液压剪和裂土器。

Excavators can not only transport materials such as earthwork by installing different accessories, but also be used for crushing, fracturing, shearing, and other materials. There are three main types of equipment for material rupture excavators, namely crushing hammers, hydraulic shears, and soil breakers.

(1)破碎锤

(1) Crushing hammer

破碎锤又称液压破碎器,是挖掘机应用相当广泛的一种特殊机具,主要用于建筑、道路拆除工程以及矿山石料破碎工作。现在已经有很大一部分挖掘机,在出厂时都标配了液压破碎管路。

Crushing hammer, also known as hydraulic crusher, is a special tool widely used in excavators, mainly used in construction, road demolition projects, and mining stone crushing work. A large number of excavators now come standard with hydraulic crushing pipelines when they leave the factory.

(2)裂土器

(2) Ripper

普通挖掘机的铲斗挖掘土方、碎石等相对松软物料时,可轻松穿透基料从而实现挖掘,但当基料被长时间压实或为整块岩石,其则不能正常挖掘。遇到此种状况,一般通过破碎等方法先碎裂表面后再进行挖掘。

When the bucket of a regular excavator excavates relatively soft materials such as soil and gravel, it can easily penetrate the base material to achieve excavation. However, when the base material is compacted for a long time or is a whole piece of rock, it cannot excavate normally. When encountering such a situation, the surface is generally crushed first and then excavated through methods such as crushing.
