Description

Technical Field

[0001] This utility model relates to the field of faucet technology, and in particular to a detachable faucet for a sand core drilling rig. Background Technology

[0002] Drilling rigs play an irreplaceable role in mineral resource exploration and development, geological surveys, hydrological well drilling, geothermal drilling, and environmental sampling. The drilling fluid circulation system is a key component ensuring the safety, efficiency, and smooth operation of drilling operations. It includes pump trucks, delivery pipelines, swivels, drill pipes, and drill bits, primarily used to carry and suspend rock cuttings, cool and lubricate drill bits and tools, and stabilize the wellbore. The swivel connects the drilling rig's hoisting, rotation, and circulation systems, ensuring the delivery of drilling fluid while also serving as a transitional connection. Therefore, its structural design needs to meet certain strength and rigidity requirements, and its sealing performance directly determines the swivel's service life and the drilling rig's working efficiency.

[0003] In the existing technology, the faucet spindle rotates with the output shaft of the power head. Wear is easily generated between the internal seals and the spindle, which can cause drilling fluid leakage and affect drilling efficiency. Therefore, the faucet needs to be disassembled and its internal parts replaced frequently. However, the existing faucets are generally fixed to the output shaft of the power head using flanges and bolts, which makes installation and disassembly complicated, and the maintenance, repair and replacement of the faucet is time-consuming.

[0020] Example 1

[0021] like Figures 1-2As shown, this utility model provides a technical solution: a detachable faucet for a sand core drilling rig, comprising: a locking nut 2, an intermediate shaft 22 at one end of the locking nut 2, screws 5 inside the locking nut 2 and the intermediate shaft 22, a rectangular key 4 inside the intermediate shaft 22, a drill rod connector 16 at one end of the intermediate shaft 22, a rectangular key 18 fixedly connected inside the intermediate shaft 22, a water jacket shell 10 on the outer surface of the intermediate shaft 22, V-shaped pressure caps 13 on the outer surface of the intermediate shaft 22, a water jacket shell 10, V-shaped end caps 23 and 15, screws 6 inside the end caps 23, 15, and the water jacket shell 10, a bushing 12 on the outer surface of the intermediate shaft 22, two sets of lip seals 8 and two sets of V-shaped seals 9 between the bushing 12 and the water jacket shell 10, and a V-shaped seal 9 on the outer surface of the intermediate shaft 22. The support ring 20 and the water jacket housing 10 are threaded with a straight connector 11. The water jacket housing 10 is fixedly connected to the outer surface of the water jacket connecting frame 24. An O-ring 14 is provided at the connection between the intermediate shaft 22 and the drill rod connecting head 16. The power head output shaft 1 is sleeved inside the locking nut 2. The power head output shaft 1 is threadedly connected to the locking nut 2. Screw 2 5 is slidably connected to the locking nut 2. Screw 2 5 is threadedly connected to the intermediate shaft 22. Rectangular key 4 is fixedly connected to the intermediate shaft 22. Rectangular key 4 is sleeved inside the power head output shaft 1. Rectangular key 4 is slidably connected to the power head output shaft 1. Screw 3 is sleeved inside both the power head output shaft 1 and rectangular key 4. Screw 3 is threadedly connected to both rectangular key 4 and power head output shaft 1. Screw 4 17 is sleeved inside the drill rod connecting head 16 and rectangular key 2 18. Screw 4 17 is slidably connected to the drill rod connecting head 16.

[0022] In this embodiment, the design of the locking nut 2 enhances the reliability of the power head output shaft 1, intermediate shaft 22, and axial fixation, preventing loosening. Simultaneously, the screw 2 5 is threadedly connected to the intermediate shaft 22, ensuring easier disassembly of the locking nut 2. The rectangular key 4 and screw 3 further strengthen the shaft connection between the power head output shaft 1 and the intermediate shaft 22. The rectangular key 18 and screw 17 enable shaft connection between the intermediate shaft 22 and the drill pipe connector 16, ensuring the reliability of the connection between the drill pipe connector 16, intermediate shaft 22, and power head output shaft 1, improving torque transmission efficiency, and preventing slippage. The O-ring 14 seals the connection between the drill pipe connector 16 and the intermediate shaft 22.

[0023] Example 2

[0024] like Figures 1-2As shown, screw 17 is threadedly connected to rectangular key 18. Bearing 7 is sleeved on the outer surface of intermediate shaft 22. Mounting grooves that match bearing 7 are provided on intermediate shaft 22, water jacket housing 10, and V-group pressure cap 13. Screw 6 is slidably connected to end cap 23 and end cap 15.

Sealing grooves that match O-rings 21 and 19 are provided on bushing 12. O-ring 14 is placed inside drill pipe connector 16.

[0025] In this embodiment, a dual sealing design of lip seal 8 and V-group seal 9 is provided to effectively prevent leakage of high-pressure water or mud, and improve the sealing reliability of the faucet. The bearing 7 adopts a fitting installation groove design, which is convenient for installation and replacement, and improves service life. In addition, the V-group support ring 20 can enhance the axial positioning capability of the bearing 7 and prevent the bearing from shifting due to vibration or impact.

[0026] Working principle:

[0027] like Figures 1-2As shown, in use, the power head output shaft 1 is horizontally fixed on the mounting platform and connected to the intermediate shaft 22. At this time, the rectangular key 4 will be embedded inside the power head output shaft 1. Then, the screw 3 is installed so that it is threadedly connected to the rectangular key 4 and the power head output shaft 1. Thus, the power head output shaft 1 and the intermediate shaft 22 are in a stable connection state. Then, the locking nut 2 is slid on the power head output shaft 1 and threadedly connected to it until the locking nut 2 and the intermediate shaft 22 are in contact. Then, the screw 5 is passed through the locking nut 2 and threadedly connected to the intermediate shaft 22. Then, the V-group support ring 20 and the bearing 7 are sequentially fitted onto the intermediate shaft 22. The water jacket housing 10 is installed, ensuring that the bearing mounting groove is accurately positioned. The bushing 12 is installed, paying attention to the installation direction of the O-ring 19 and the O-ring 21. The lip seal 8 and the V-group seal 9 are pressed in using a special tool. The end cap 15 and the end cap 23 are sealed. Apply sealant to the cover, align the end cap with the locating pin hole of the water jacket housing 10, insert screw 6, manually screw in 3-4 threads first, and gradually tighten all screws using the cross-tightening method. Clean the tapered surface of the end of the intermediate shaft 22, insert O-ring 14 into the sealing groove of the drill pipe connector 16, insert rectangular key 18 into the keyway of the drill pipe connector 16, align the end of the intermediate shaft 22 and push the connector in, insert screw 17, first thread it to the rectangular key 18, and tighten it twice with a torque wrench, first to 30% of the specified torque and second to 100% of the specified torque. Check that the radial runout of the connector is ≤0.1mm. Wrap sealing tape around the thread of the straight connector 11, screw it into the water jacket housing 10 to the hand-tight state, and use a pipe wrench to rotate it another 1.25 turns to complete the tightening. Connect the external cooling pipes, align the water jacket connector 24 with the mounting base, use the locating pin to initially fix the position, tighten the connecting bolts in diagonal order, and finally check the overall coaxiality.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
