5results about How to "Guaranteed drilling efficiency" patented technology

This utility model relates to the field of cast-in-place pile construction technology, specifically to a suspended mud pump, including a mud pump body, a support assembly, and a floating assembly. The support assembly has a centrally located space for mounting the mud pump body, which is situated within this space. The floating assembly is positioned around the support assembly and includes at least two suspension units. These suspension units provide buoyancy to support the mud pump body. The mud pump body reciprocates based on these suspension units, following changes in the mud slurry level. The mud pump body has a suction port located at its lower part, flush with the bottom of the floating assembly. This design prevents the water level from exceeding the motor's height or causing idling, extending equipment lifespan. Furthermore, by maintaining a reasonable relative depth between the suction port and the liquid surface, fluctuations in suction resistance are reduced, ensuring stable mud circulation flow.

The utility model discloses a device for T iron drilling, including fixed platform for placing and fixed T iron still includes: elevating platform, solidly installs on the fixed platform, and the elevating platform is installed with the elevating plate of horizontal setting, and the elevating plate can along with elevating platform vertical reciprocating lifting movement, drilling mechanism, installs on the elevating plate, including: a plurality of drill bits, can clockwise rotatably set in the bottom of elevating plate, motor, the number is one, set up in the elevating plate top, transmission structure, install on the elevating plate between motor and a plurality of drill bits, for the kinetic energy transmission of motor to each drill bit. In the scheme, minimum can only set up one motor, can drive a plurality of drill bits to carry out drilling, need not to equip each drill bit with a corresponding motor, greatly reduces the power consumption of whole device, makes each drilling equipment normal work operation to keep in a low power consumption level, has realized the purpose of reducing enterprise production cost, finally realized the purpose of improving economic efficiency.

The application relates to the technical field of drilling devices, and discloses a drilling device for metal computer support machining and an operation method thereof, which comprises a driven feeding mechanism and a buffer liquid flow control mechanism. The drilling device for metal computer support machining and the operation method thereof utilize the liquid output by a hydraulic system to control the feeding of a drill bit, realize systematic feeding pressure control on the basis of guaranteeing the driven feeding, can guarantee the drilling efficiency of the drill bit on the metal computer support and the effective utilization rate of kinetic energy on one hand, and can effectively prevent the drill bit and the metal computer support from being deformed due to the overloading of the feeding pressure on the other hand, so that the limitation of the equipment in the use process is reduced, and the self-adaptability of the equipment is improved.

The utility model relates to the technical field of oil exploitation, and discloses an oil exploitation sampling device which comprises a box body, a mounting plate is arranged in the box body, a drill rod is arranged on the lower side of the mounting plate, a sampling bin is fixedly connected to the lower side of the drill rod, and a drill bit is arranged at the lower end of the sampling bin. An electric push rod is arranged in the drill rod, the telescopic end of the electric push rod penetrates into the sampling bin in a sliding mode, the telescopic end of the electric push rod is fixedly connected with a push plate, and through cooperation of a fixing ring, a sealing ring, a filter plate, a flow guide block and other structures, petroleum is filtered, so that the sampling efficiency is effectively improved, and the service life of equipment is effectively prolonged; meanwhile, the condition that impurities are mixed into the sample is effectively avoided, the accuracy of subsequent petroleum sample detection is improved, a reliable basis is provided for subsequent production and analysis, and the practicability is high.

The invention provides a geotechnical engineering sampling drill bit and a manufacturing method thereof. The drill bit comprises a drill bit shell, which is a hollow cylindrical structure with one end closed and the other end provided with drill teeth; a threaded hole is formed in the center of the closed end of the drill bit shell. The drill teeth comprise outer tooth structures and inner tooth structures. The outer tooth structures are multiple and evenly distributed along the outer edge of the end of the drill bit shell. The inner tooth structures are multiple and evenly distributed along the inner edge of the end of the drill bit shell. The outer edge of the outer tooth structure is larger than the outer edge of the end of the drill bit shell. The inner edge of the inner tooth structure is smaller than the inner edge of the end of the drill bit shell. The invention adopts split casting to ensure the structural strength of the drill teeth and the drill bit, and the processing technology is simple and easy to manufacture. In addition, the triangular drill teeth not only ensure the drilling efficiency, but also have strength and stability, and are easy to use.
