جهاز حفر الأساسي للزاحف الهيدروليكي بالكامل
The surface core drilling rig is one kind of hydraulic top drive rotary head type drilling rig, which is mainly used in diameter diamond drilling of metal and nonmetal solid deposit exploration. It can be used in carbide bit core drilling. It is used to bore vertical holes as well as inclined holes, which is also applied in engineering boreholes of hydrology water wells, petroleum or gas field exploration, dike & dam cement grouting, tunnel ventilation and water draining, etc.
The rig takes advantage in its high rotary speed, reasonable rotary speed range, various rotary speed grades, and big torque at low speeds. Hence, it’s very suitable for small diameter diamond bit core drilling. Meanwhile, it can meet the requirements of large diameter carbide bit core drilling and a variety of engineering boreholes.
ميزات الحفر الأساسي للزاحف الهيدروليكي بالكامل
It has a long stroke, which is helpful to reduce the rod reversion frequency, avoid coring block, and improve productivity.
It has a simple structure, a light weight and is convenient to remove, so as to make the replacement process easy.
Its operation is concentrated, simple, convenient, flexible, and reliable, so as to reduce labor intensity a lot.
It needn’t be provided with a special inclined tower when drilling inclined holes. It can also realize raising two rods at one time.
It is convenient and fast to mount and install the rig. No specialized drill tower is needed to allocate, which has largely cut the preparation time.
It has several choices of the chassis, such as skid/trailer/crawler mounted(as the customers’ requests)
