挖机设备在使用时有哪些基本的操作要求

日期:2022-08-26   来源:http://www.dybocheng.com
长臂挖掘机是一种比较常见的机器,这种机器的作用非常的多,不过一定要正确的操作,如果不正确操作就会影响长臂挖掘机的使用效果。那么,长臂挖掘机在使用的时候有哪些基本的操作要求呢?
The long arm excavator is a common machine, which has many functions. However, it must be operated correctly. If it is not operated correctly, the use effect of the long arm excavator will be affected. So, what are the basic operating requirements of the long arm excavator when it is used?
1、准备工作,在开挖过程中,首先需对沉井进行测量,调查偏斜程度,同时把井顶连接筋统一向外弯成90度与井顶平行,并割除井壁内、外侧伸出的拉筋头,以减少沉井下沉阻力以及钢筋头对铲斗挖齿所造成的损伤。对沉井四周的地表进行平整,以便停靠机械。
1. Preparatory work: during the excavation process, the open caisson shall be measured first to investigate the deflection degree. Meanwhile, the connecting bar on the shaft top shall be uniformly bent outward to 90 degrees parallel to the shaft top, and the tie bar heads protruding from the inside and outside of the shaft wall shall be cut off to reduce the sinking resistance of the open caisson and the damage caused by the steel bar head to the bucket teeth. The surface around the caisson shall be leveled to facilitate the parking of machinery.
2、停靠机械,根据长臂挖掘机的特点,选择适当位置停靠机械,所选位置必须保证挖掘机的斗杆与动臂能在井孔中完全垂直下伸,而且后壁与井壁能保持一定的高度,避免碰撞。
2. Parking machinery: according to the characteristics of the long arm excavator, select a suitable position to park the machinery. The selected position must ensure that the bucket arm and boom of the excavator can be fully vertically extended in the well bore, and the rear wall and the well wall can maintain a certain height to avoid collision.
在井顶安排一名值班员负责挖掘机开挖井底时的现场指挥,挖掘机司机根据目测结果以及值班员的手势进行操作。
A watchman shall be arranged at the top of the well to be responsible for the on-site command of the excavator when excavating the bottom of the well. The excavator driver shall operate according to the visual inspection results and the gesture of the watchman.
长臂挖掘机
先将动臂前倾15度,使铲斗挖齿能垂直井孔下沉至底部,然后根据下挖的阻力使铲斗挖齿能够垂直井孔下沉至底部,然后根据下挖的阻力使铲斗勾回装满,提升前臂与斗杆使铲斗离开井孔,旋转主机底盘将铲斗移至沉井5米外倒掉。
First, tilt the boom forward by 15 degrees, so that the bucket teeth can sink to the bottom of the vertical well hole, then make the bucket teeth sink to the bottom of the vertical well hole according to the resistance of the down excavation, then hook the bucket back to the full according to the resistance of the down excavation, lift the forearm and the bucket rod to make the bucket leave the well hole, rotate the chassis of the main machine to move the bucket 5 meters away from the open caisson and pour it.
如此反复6次,再转向另一井孔的开挖,使沉井底部锅底均匀形成。在开挖过程中,会看到井壁四周的土体产生一定程度的塌陷,沉井逐渐下沉。
Repeat this for 6 times, and then turn to the excavation of another well hole to form the bottom of the caisson evenly. During excavation, the soil around the shaft wall will collapse to a certain extent, and the caisson will gradually sink.
4、降低长臂挖掘机高度,当井顶距水位线50cm时停止开挖,在此期间应减少每个井孔的开挖次数,加强左右井孔的开挖交错频率,使沉井均匀下沉;当地下水位较低时,可在挖掘机的铲斗探不到井孔底部时,明挖扩大井孔两侧的土体,以便降低长臂挖掘机的主体高度,充分利用铲斗进行沉井底部的取土作业。。
4. Reduce the height of the long arm excavator and stop the excavation when the well top is 50cm away from the water level. During this period, the excavation times of each well hole shall be reduced, and the excavation staggered frequency of the left and right well holes shall be strengthened to make the caisson sink evenly; When the underground water level is low, when the bucket of the excavator cannot reach the bottom of the well hole, open excavation can expand the soil mass on both sides of the well hole, so as to reduce the main body height of the long arm excavator and make full use of the bucket to carry out the soil borrowing at the bottom of the caisson..
