Q Double Tube Core BarrelAssembly

The Q Double Tube Core BarrelAssembly product is a component of its rope core drilling tool, mainly used in geological exploration and other fields. The Q series upper assembly is a related product of its rope core drilling tool, mainly used in geological exploration, mineral resource development, water conservancy and hydropower engineering, tunnel construction and other scenarios that require the collection of underground rock core samples. The double tube assembly of the Q series rope core drilling tool consists of an outer tube assembly and an inner tube assembly. The upper assembly is usually closely related to the inner tube assembly and involves components such as the fishing head, positioning mechanism, adjustment mechanism, suspension mechanism, etc. The positioning mechanism can prevent the inner tube from moving upwards; The suspension mechanism maintains a certain gap between the lower end of the inner tube assembly and the inner step of the drill bit, ensuring the single movement performance of the inner tube; The single action mechanism consists of two sets of thrust bearings, which prevent the inner pipe from rotating during drilling; The regulating mechanism is composed of regulating nuts, etc; The in place reporting mechanism consists of a spring card holder, steel balls, etc. It can determine whether the inner pipe has reached the drilling position through the pressure change of the ground pressure gauge. As a professional drilling equipment production enterprise, Wuxi Xizuan's Q series upper assembly products have reliable quality and good coordination with other components, which can ensure the stable performance of the rope core drilling tool, improve the efficiency and quality of core collection, reduce in hole accidents, and provide strong support for geological exploration and other work.
