1). The  up  drilling rig has the following advantages

1. The raise drilling rig main parameters such as pushing, pulling force, rotating torque and rotating speed of the drilling rig are reasonable in design, and the drilling process is simple, which can meet the construction requirements under different geological conditions and various apertures;

2, Raise bore drilling machine using full hydraulic drive, compact structure, light weight, power saving;

3, Raise boring machin the host installation and transportation and adjustment of all mechanization, simple and labor-saving, rapid and safe, no need for auxiliary equipment;

4, Mine drilling rig the host hydraulic system is simple and reliable, easy to operate, most of the hydraulic components use the national standard series of brand-name components, easy to repair and replace;

5. The coal drilling rig drilling   process realizes mechanized operation, the operation is simple and safe, the working conditions are improved, and the labor intensity is reduced;

6. The drilling machine Drill pipe thread adopts API international general standard, safe and reliable, good interchangeability, long service life, reasonable process of loading and unloading drilling tools, short auxiliary time, drilling machine with open hole drill pipe and special stable drill pipe, which can effectively Prevent wellbore deflection;

7. The  drill rig has strong applicability and can be constructed under more complicated geological conditions;

8. The drilling rig is explosion-proof and suitable for use in environments with flammable gases at all levels;

9. The anti-well drilling rig has high efficiency, good speed forming block and good quality.

2). The big diameter up  drilling rig Taper worm gear hob has the following advantages

With the development of the times, hobs are widely used in the machinery industry. There are many types of hobs. Taper worm hobs are one of them. Do you know the characteristics of taper worm hobs? If you still don"t understand,

The drilling rig In the complex gear tool manufacturing industry, worm gear machining requires a special taper worm gear hob. The accuracy of the worm gear depends on the accuracy of the worm wheel hob, especially the large spiral angle worm gear hob (the worm wheel hob with a helix angle greater than 30°). The accuracy error is very high, so it is especially important to accurately detect the accuracy error of the large spiral angle worm hob. The taper worm gear hob is determined by the worm and there are no standardized tools. Generally made by the hob zk type. At the same time, the worm wheel hob determines the size of the hob by the worm and worm gear specifications.

The drilling machine type and main parameters of the basic worm (see worm drive) of the tapered worm hob (modulus, tooth angle, index circle diameter, screw hob angle and number of threads) should be the same as the working worm, so the worm wheel Knives are often dedicated. When the outer diameter is large, the hob is made into a set type; when the outer diameter is small, the hob is made into a shank structure integrated with the mandrel.

Taper worm gear hob features

1. Raise boring machine Axial modulus or tooth direction modulus, diameter section

2. Raise boring machine Pressure angle (tooth vertical, axis vertical)

3. Raise boring rig The outer diameter or pitch diameter of the worm wheel

4. Worm chamfering

5. Number and direction of the worm wheel

6. Handle type handle specifications

7. The standard contact rate of worm gear and worm is suitable for ordinary 20-30%. The inner diameter form or the shank type can be selected.
