                  ZFY1.2 / 20 / 200D low-profile reverse rig (formerly ZFYD1200)

                  Introduction of ZFYD1200 reverse well drilling rig:
                  The reverse well drilling rig is a kind of highly mechanized, safe and efficient reverse well construction equipment. In particular, it can greatly increase the construction speed when drilling reverse shafts, underground coal bunkers, coal slips, extended shafts, and various dark shafts in coal mines. It also has the advantages of reducing workers' labor intensity, operating safety, and good well quality.

                  ZFYD1200 reverse well drilling rig uses:
                  It is suitable for construction operations such as underground coal bunkers, concealed (inclined) wells, pipeline holes, cable holes, coal slip holes, ventilation holes, etc. It is applicable to the case of rock hardness coefficient f≤12.

                  反井钻机的结构特点 Structural Features of ZFYD1200 Reverse Drilling Rig

                  (1) Adopting the structure of two columns and three cylinders, the rig frame is directly anchored to the foundation bedrock, which makes the rig as a whole rigid and has a large bearing capacity.
                  (2) The telescopic sleeve cylinder is used as the propulsion cylinder of the drilling rig, which greatly reduces the working height of the drilling rig, which is generally 2500 ~ 2900mm (see the attached table for details). When using a low-profile reverse rig to construct a dark vertical shaft, the excavation chamber will work. The small amount (or no excavation) reduces the consumption of people, money and materials, and shortens the preparation period in the early stage of construction.
                  (3) The symmetrical arrangement of the three propulsion cylinders is connected by an equilateral triangle. The center of gravity of this triangle is the center of rotation of the rig. This is one of the factors for the smooth operation of the rig and the accuracy of drilling and expanding.
                  (4) Mechanization of loading and unloading of drill pipes, and overall transport of self-carrying vehicles. The ZFYD series of low-profile back-drilling rigs have been successfully developed, which provides an advanced, efficient and safe construction equipment for the construction of hidden shafts in China, and has been well received by users in the field.

                  Compared with similar domestic models, the low backwell drilling rig designed and developed by our company has the following advantages:

                  、钻机的工作高度低。 1. The working height of the rig is low. The telescopic sleeve cylinder is used as the propulsion oil cylinder of the rig, which greatly reduces the working height of the rig. When a low-profile reverse rig is used to construct a dark vertical shaft, the work in the excavation chamber is small (or not excavated), which reduces the personnel, financial, and labor costs. Consumption of materials shortens the preparation period in the early stage of construction.
                  、采用国际上较为先进的三缸两柱式结构,整体钢性较强,稳定性好,承载能力大。 2. It adopts the internationally advanced three-cylinder two-column structure, which has strong overall rigidity, good stability and large bearing capacity.
                  、三只推进油缸对称布置,其中心连线为一等边三角形,这三角形的重心就是钻机回转中心,这是钻机运转平稳因素之一,钻扩孔精度高。 3. The three propulsion cylinders are symmetrically arranged, and the center line is an equilateral triangle. The center of gravity of this triangle is the center of rotation of the rig. This is one of the factors for the smooth operation of the rig and the precision of drilling and reaming is high.
                  、钻、扩孔效率高。 4. High drilling and reaming efficiency. 扩孔速度: 1.5m/h,接一根钻杆所需时间:510分钟,卸一根钻杆所需时间:1015分钟。 Speed of drilling pilot hole: 4.3m / h, reaming speed: 1.5m / h, time required to connect a drill pipe : 5 to 10 minutes , time to unload a drill pipe : 10 to 15 minutes.
                  、滚刀使用寿命长。 5. The hob has a long service life. 镶齿盘形滚刀,生产使用中寿命达550米。 This type of drilling rig uses the DXP-1 cog-shaped disc hob developed jointly by our company and Nanjing Coal Science Research Institute.
