长臂挖掘机有哪些应用领域?

日期:2021-11-16   来源:http://www.dybocheng.com
市政建设、地铁交通的完善、下水道的改建、河道清理等都须要大量的工程机械设备,而标准的挖掘机械又完成不了特殊化的工程作业,所以此时加长臂挖掘机利用超长型动臂和超长型斗杆来大展神威,可在疏浚、护岸、坡面以及地铁建设等受地面环境限制的工况下,发挥巨大的威力
Municipal construction, improvement of subway traffic, reconstruction of sewers, river cleaning, etc. all require a large number of engineering machinery and equipment, and standard excavation machinery can not complete specialized engineering operations. Therefore, at this time, the extended arm excavator uses super long boom and super long bucket rod to show its great prestige, which can be used in dredging, revetment Slope and subway construction play a great power under the conditions limited by the ground environment

一般常见的长臂挖掘机有以下几个应用领域:
Common long arm excavators have the following application fields:
1.两段式加长臂:使用范围相对较大,但是他的主要功能也只是为了提升挖掘半径,主要用于清理河道,填海造地,地铁出入口开挖,人行地底隧道,还有高速公路防护墙修整,一般住宅输送一下水泥等等。也有人用他前置破碎锤作用于房屋拆迁的,不过比较危险。两段式加长臂一般10-26米区间改装比较多。
1. Two section lengthening arm: the scope of use is relatively large, but its main function is only to improve the excavation radius. It is mainly used for river cleaning, land reclamation, subway entrance and exit excavation, pedestrian underground tunnel, expressway protective wall repair, general residential transportation of cement, etc. Some people also use his front breaking hammer to act on house demolition, but it is more dangerous. The two-stage lengthening arm is generally refitted in the interval of 10-26m.
2.三段式加长臂:或者多段式加长臂,主要应用于高层建筑的拆迁,前置破碎锤或者液压钳。20-28米内使用者比较多。
2. Three section lengthening arm: or multi section lengthening arm, which is mainly used for demolition of high-rise buildings, front crushing hammer or hydraulic tong. There are many users within 20-28 meters.
3.滑臂或者内伸缩臂:主要为了回转半径很小,但是挖掘深度要求很高的工况设计,一般会前置贝壳挖斗(贝形斗)。滑臂垂直挖掘深度一般为10米,内伸缩臂垂直挖掘深度一般在26米以内。
3. Sliding arm or inner telescopic arm: it is mainly designed for working conditions with small turning radius but high excavation depth requirements. Generally, it will be preceded by shell bucket (shell bucket). The maximum vertical excavation depth of the sliding arm is generally 10m, and the vertical excavation depth of the inner telescopic arm is generally within 26m.
4.打桩机加长臂:大小臂平直,前置弯臂2.6米左右(主要是为了与振动锤连接是便于阀块和管路的安装)及震动锤,应用于修建公路铁路或者埋设管道的时候打拔钢板桩。
4. Lengthening arm of pile driver: the big and small arms are straight, and the front bending arm is about 2.6m (mainly to connect with the vibrating hammer to facilitate the installation of valve block and pipeline) and the vibrating hammer are used to drive and pull out steel sheet piles when building roads and railways or burying pipelines.
5.抓木机、抓料机装卸煤机加长臂:更多的时候为了装卸火车或者汽车而设计,一般大臂7.6米,小臂5-6米.前置抓木器、抓钳器或者贝壳挖斗。
5. Wood grabbing machine, material grabbing machine and coal handling machine lengthening arm: more often, it is designed for loading and unloading trains or cars. Generally, the big arm is 7.6m and the small arm is 5-6m. The front wood grabber, gripper or shell bucket.
挖掘机大小臂改装前提是要考虑动力,液压以及配重平衡几个方面。
The premise of refitting large and small arms of excavator is to consider power, hydraulic pressure and counterweight balance.
什么样的挖掘机可改装成长臂挖掘机
What kind of excavator can be modified into a long arm excavator
新机不建议改装,因为改装成长臂挖掘机以后,挖掘机负荷增大,况且没过保修期容易与原厂产生售后服务的纠纷;
It is not recommended to refit the new machine, because after refitting the long arm excavator, the excavator load increases, and it is easy to have after-sales service disputes with the original factory before the warranty period expires;
五成新以下的机也不建议改装,因为机器使用年限比较旧,各方面性能减退,加上加长臂本身也有一定重量,很难发挥出加长臂挖掘机应有的效率,更好的是5-8成新的挖掘机改装成加长臂挖掘机。
It is not recommended to refit less than 50% of the new excavators, because the service life of the machine is relatively old and the performance of all aspects decreases. In addition, the lengthening arm itself has a certain weight, so it is difficult to give full play to the due efficiency of the lengthening arm excavator. The best thing is to refit 5-80% of the new excavators into the lengthening arm excavator.

加长臂应排除的问题
Problems to be eliminated in lengthening arm
旧挖掘机标准臂改装挖掘机加长臂,首先要衡量挖掘机的使用性能,如液压输出是否达到一定压力;行走机构、转盘结构等是否能承载挖掘机加长臂,承载多长的加长臂?
When refitting the standard arm of an old excavator into an extended arm of an excavator, we must first measure the service performance of the excavator, such as whether the hydraulic output reaches a certain pressure; Whether the traveling mechanism and rotary table structure can bear the lengthening arm of the excavator and how long the lengthening arm can bear?
旧挖掘机使用年限以及施工作业时间长短等原因,对挖掘机本身的性能好坏有着直接影响,比如没挖掘力,举臂无力,行走缓慢等。挖掘机有着这些原因,改装成加长臂后,很难发挥出加长臂挖掘机应有的效率。
The service life and construction time of the old excavator have a direct impact on the performance of the excavator itself, such as no excavation force, weak arm lifting, slow walking, etc. For these reasons, it is difficult to give full play to the due efficiency of the extended arm excavator after it is refitted into an extended arm.
在改装前更好对挖掘机进入质量检测,通过质量检测,更清楚的了解自身挖掘机性能,才能选择更适配的加长臂进行改装!
Before refitting, it is best to enter the quality inspection of the excavator. Through the quality inspection, you can better understand your excavator performance, so as to select a more suitable lengthening arm for refitting!
