Bearing Use of Crawler Down-the-Hole Drill

图片
  Bearings are familiar to everyone and are closely related to our lives and work. From bicycles to automobiles or construction machinery, there are bearings, and Drilling Rig is inseparable from them. The bearings of the   Advanced Crawler Mounted DTH Drilling Rig   are precision parts, and they must be maintained in daily work to make it more effective. Pay attention to the following points when using bearings. When installing the bearing, do not press hard, do not use a hammer or other hard objects to strike, and do not transmit pressure through the rolling elements; use professional tools when installing, do not brute force; usually keep the rotary excavator bearing clean, Even a trace of dust may cause bearing wear; the bearings of rotary excavators should be treated with rust prevention. The bearing is a precision part of the crawler drilling rig. The damage of one small thing will cause the failure of the entire crawler drilling rig. Therefore, we must pay att...

Preparation Work Before Hydraulic Dth Drill Rig Construction.

  The construction of hydraulic down-the-hole drilling rigs has the characteristics of fast hole formation, high quality, no noise, and no pollution. Because of its unparalleled advantages in the construction of cast-in-place piles, it is favored by more and more construction units. Therefore, the current price segment Drilling rigs are the main force in underground engineering construction. 1. Construction site:  hydraulic DTH Drilling Rig  for pile foundation construction. In the preliminary preparation stage, the construction site is required to be high. Due to the heavyweight of the rotary drilling rig, the operation of the rotary drilling rig requires the machinery to remain stable, so the operation The site reaches a certain bearing capacity. If the working surface is a relatively soft stratum, the supporting layer should be backfilled so that the site can carry the  hydraulic DTH Drill Rig , and the cranes (above 25t), concrete filling trucks and other eq...

How to Choose Drill Bits In Borehole Drilling Machine Construction?

图片
  1. The main function of   Advanced Crawler Mounted DTH Drilling Rig  is to dig holes on the surface. Due to the different depths of the pile holes to be constructed, various terrain structures will be encountered during drilling. It can be roughly divided into the following categories: (1) Clay: Use a rotary drilling bucket with a single bottom. If the diameter is small, use a two-part bucket or a bucket with a soil unloading plate. (2) Silt, low-cohesive soil layer, sandy soil, and poorly cemented pebble layer with a small particle size can be equipped with a double-bottom drilling bucket. (3) Hard clay: Use a rotary drilling bucket with a single inlet (single and double bottoms), or a bucket tooth straight screw. (4) Frozen soil layer: Bucket-tooth straight spiral drill bucket and rotary drilling bucket with low ice content can be used, and cone spiral drill bit with high ice content can be used. It should be noted that spiral drill bits are used for soil layers (exce...
