提高挖掘机挖斗生产率应该从哪些点出发?

日期:2020-04-20   来源:
做好施工前的预备
Make preparations before construction
正确的施工安排设计。与发掘机配合的自卸车数量及承载才能应满意发掘机生产才能的要求,且自卸车的容量应为发掘机挖斗容量的整数倍。同时尽量采用双放装车法,使发掘机装满一辆,紧接着又装下一辆,因为两辆自卸车别离停放在发掘机挖斗卸土所能及的圆弧线上,这样挖斗顺转装满且车,反转又可装满另一车,然后提高装车功率。
Correct construction arrangement design. The quantity and bearing capacity of the dump truck matched with the excavator shall meet the requirements of the production capacity of the excavator, and the capacity of the dump truck shall be an integral multiple of the excavation bucket capacity of the excavator. At the same time, try to use the double loading method to make the excavator full of one, and then load the next. Because the two dump trucks are separated and parked on the arc line where the excavator bucket can unload soil. In this way, the bucket can be turned forward to be full and the car can be turned back to be full of another car, and then the loading power can be increased.
拟定正确的自卸车行驶路线。在施工安排中,应事先拟定好自卸车的行驶路线,清除不必要的上坡道。对于发掘机的各掘进道,须要做到各有一条空车回程道,以免自卸车进出时彼此搅扰,各运转道应坚持杰出善,以利自卸车运转。
Draw up the correct route of dump truck. In the construction arrangement, the driving route of dump truck shall be prepared in advance, and unnecessary ramps shall be removed. For each roadheader of the excavator, it is necessary to have an empty return road to avoid mutual disturbance when the dump truck enters and exits. Each transfer road shall adhere to excellence to facilitate the operation of the dump truck.
把握节能操作方法
Grasp the operation method of energy saving
在高功率区发掘。高功率区是指小臂从笔直状况向前面移动45度到向前移动30度之间的规模,在该规模内发掘,以装满挖斗为宜。(该规模依据机械不同而有所不同)
Excavate in high power area. The high-power area refers to the scale of the forearm moving 45 degrees to 30 degrees forward from the straight state. It is better to excavate in this scale to fill the bucket. (the scale varies according to the machinery)

不进行多余的发掘。发掘机挖斗盛满后持续发掘将形成燃料糟蹋,好像引起液压开释等负荷过重情况,只会无畏地耗费燃料,因此请防止。
No unnecessary excavation. After the hopper of the excavator is full, continuous excavation will result in fuel waste. It seems to cause overload such as hydraulic release, which will only consume fuel fearlessly, so please prevent.
在发掘力较大的方位进行操作。在作业机和气缸角度成90度时发掘力较大,发掘力首要运用挖斗的挖出力。
Operate in the direction of large excavation force. When the angle between the working machine and the cylinder is 90 degrees, the excavation force is larger, and the excavation force is mainly the excavation force of the bucket.
适时做好保护保养
Timely protection and maintenance
挖斗加固。发掘机挖斗在运用时,锯齿作为机械末端的装置,特别容易受损,如果条件允许的话,建议运用发掘机前能够先对挖斗进行加固,这样才能够保障挖斗愈加经久耐用,有效的提高作业功率,下降作业成本。
Bucket reinforcement. When the excavator bucket is used, the saw tooth is the device at the end of the machine, which is particularly vulnerable to damage. If conditions permit, it is recommended to reinforce the bucket before using the excavator, so as to ensure that the bucket is more durable, effectively improve the operation power and reduce the operation cost.
防止挖斗尾部刮擦。发掘机挖斗作业前,应将作业环境进行清理,把旋转半径内高出履带板的所有障碍物扫平。正常情况下,发掘机挖斗尾部出现刮擦多是旋转的时分形成的,所以操作人员要对尾部旋转半径数据有所了解,这样,在作业的时分,留出合适的间隔,才能防止在旋转的时分出现刮擦。
Prevent scraping at the end of the bucket. Before digging, the working environment shall be cleaned and all obstacles higher than the track shoes within the rotating radius shall be cleared. Under normal circumstances, the scraping at the tail of the excavator bucket is mostly caused by the time of rotation, so the operator should know about the data of the tail rotation radius, so that the appropriate interval can be set aside during the operation to prevent the scraping at the time of rotation.
