Description

Technical Field

[0001] This utility model relates to the field of oil drilling engineering technology, and more specifically, to a drilling rat hole adaptive hydraulic safety slip device and drilling equipment. Background Technology

[0002] A drilling rig is a specialized structure used for temporary storage of crisscross drill pipe. Its main function is to provide stable support during tripping operations, preventing the crisscross drill pipe from directly contacting the ground and causing damage. Currently, simple safety slips or wedges are commonly used at oil drilling sites to secure tools or drill strings in the rig. However, existing safety slips are often designed for specific diameter drill strings or tools. When the drill string diameter changes, manual removal and replacement of slips with different diameter structures are required. Therefore, traditional slips cannot be adapted to the different diameter requirements of drill strings. Manual removal and replacement of slips for matching and adjusting the drill string clamping is time-consuming and labor-intensive, severely impacting drilling efficiency. Furthermore, relying on manual experience for slip clamping operations makes it impossible to accurately control and adjust the clamping force in real time. This can lead to slips loosening under drill string vibration and impact, posing a safety risk of the drill string or tool tipping over or slipping. Summary of the Invention

[0016] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] like Figure 1-7 As shown, the drilling rat hole adaptive hydraulic safety slip device of this utility model includes a base plate 8; a hydraulic oil station 2 and a hydraulic controller 7 are fixedly installed on the upper side of the base plate 8, and the hydraulic controller 7 is connected to a manned machine control unit 1 through a wire; it also includes an oil pump 4 and a hydraulic slip device 6; the oil pump 4 is connected to the hydraulic oil station 2 through an oil pipe, the oil pump 4 is installed on the lower side of the base plate 8, and an electromagnetic reversing valve 3 is installed at the oil outlet of the oil pump 4, and the electromagnetic reversing valve 3 is connected to a flow divider valve 5 through an oil pipe.

[0018] The hydraulic slip device 6 includes an electronic liquid pressure gauge 601, a hydraulic lock 602, a hydraulic cylinder 603, a base plate 604, a guide plate 605, a push plate 606, a slip block 607, a slide rod 608, a limiting collar 609, a mounting cylinder 610, a pressure sensor 611, a mounting bracket 612, a fixing bolt 613, a connecting rod 614, a hinge bracket 615, and a support 616. The bracket 616 is bolted to the guide plate 605. A base plate seat 604 is mounted on the lower side of the guide plate 605. A hydraulic cylinder 603 is mounted on the upper side of the bracket 616. A hydraulic lock 602 is mounted on the oil inlet of the hydraulic cylinder 603. An electronic liquid pressure gauge 601 is mounted on the oil inlet of the hydraulic lock 602. A hinge frame 615 is mounted on the bottom end of the telescopic rod of the hydraulic cylinder 603. A connecting rod 614 is hinged to the bottom end of the hinge frame 615. A push plate 606 is hinged to the bottom end of the connecting rod 614. The push plate 606 is bolted to the mounting cylinder 610. The mounting cylinder 610 is bolted to the pressure sensor 611. A limit ring 609 is welded to the outer side of the slide rod 608. A mounting bracket 612 is welded to the end of the slide rod 608. A slip block 607 is connected to the front side of the mounting bracket 612 by fixing bolts 613.

[0019] In a preferred embodiment of this utility model, there are four sets of slip blocks 607. The slip blocks 607 are arranged in a ring array around the vertical central axis of the base plate 604. The centripetal surface of the four sets of slip blocks 607 is an arc structure. A large number of carbide teeth are welded to the arc structure surface of the slip blocks 607. By utilizing the high hardness and wear resistance of the carbide teeth, the slip blocks 607 can resist the friction and impact of the drill tool surface and avoid the contact surface of the slip blocks 607 from wearing out too quickly. The slip blocks 607 are provided with an opening groove that runs vertically through the top and bottom. The groove wall of the opening groove of the slip blocks 607 is provided with a through hole. A fixing bolt 613 is inserted into the through hole of the slip blocks 607.

[0020] In a preferred embodiment of this utility model, the push plate 606 is provided with two sets of cuboid protrusions. The push plate 606 has circular slots near its top and bottom ends, with through holes at the bottom of the slots. A sliding rod 608 is inserted into the through hole of the circular slot in the push plate 606. A limiting collar 609 is embedded in the circular slot in the push plate 606. The limiting collar 609 pulls and limits the mounting bracket 612 within the circular slot in the push plate 606, preventing the sliding rod 608, which is welded to the mounting bracket 612, from dislodging from the through hole of the circular slot in the push plate 606. A through hole is provided at the center of the push plate 606. The mounting cylinder 610 is inserted into the through hole structure at the center of the push plate 606. When the push plate 606 drives the slip block 607 connected to the fixing bolt 613 on the mounting frame 612 to contact the drill bit, the mounting frame 612 is pushed by the reverse force of the drill bit and moves along the sliding rod 608 in the through hole of the circular slot of the push plate 606 to form an interlocking and nesting structure. This causes the mounting frame 612 to push the pressure sensor 611 installed on the mounting cylinder 610, so that the pressure sensor 611 can measure the extrusion force of the slip block 607 on the outer surface of the drill bit in real time.

[0021] In a preferred embodiment of this utility model, four sets of through holes are provided at the four corners of the upper side of the base plate 604. By using four sets of ground nails inserted into the four sets of through holes of the base plate 604, the hydraulic slip device 6 can be easily fixed to the area around the mouse hole on the drilling platform of the drilling rig. This facilitates the direct modification and installation of the hydraulic slip device 6 on the existing mouse hole area on the drilling platform of the drilling rig. Four sets of guide plates 605 are connected to the upper side of the base plate 604 by bolts. The guide plates 605 have a fan-shaped structure. The lower side of the fan-shaped structure of the guide plate 605 has a groove. The protrusion of the push plate 606 is embedded in the groove of the guide plate 605. The groove of the guide plate 605 supports the horizontal directional movement of the push plate 606, ensuring that the slip block is stably in contact with the outer surface of the drill bit.

[0022] In a preferred embodiment of this utility model, the front side of the mounting bracket 612 is provided with a cuboid protrusion. The cuboid protrusion of the mounting bracket 612 is embedded in the opening groove of the locking block 607. The cuboid protrusion of the mounting bracket 612 is provided with a threaded through hole. The threaded through hole protrusion of the mounting bracket 612 is horizontally aligned with the through hole of the locking block 607. The fixing bolt 613 is screwed into the threaded through hole of the cuboid protrusion of the mounting bracket 612. When the carbide teeth of the locking block 607 are worn out, the locking block 607 can be quickly removed from the mounting bracket 612 and replaced by turning the disassembly fixing bolt 613. The replacement operation of the locking block 607 is simple and quick.

[0023] In this embodiment of the utility model, the hydraulic controller 7 is equipped with a PLC. The PLC of the hydraulic controller 7 is connected to the human-machine interface 1 via wires. The PLC of the hydraulic controller 7 is also connected to the electronic liquid pressure gauge 601 and the pressure sensor 611 via wires. The PLC of the hydraulic controller 7 is connected to the solenoid directional valve 3 and the hydraulic lock 602 via wires. The PLC of the hydraulic controller 7 receives feedback signals from the electronic liquid pressure gauge 601 and the pressure sensor 611, as well as setting instructions from the human-machine interface 1, via wires. Through the control algorithm built into the PLC, the solenoid directional valve 3 and the hydraulic lock 602 are controlled via wires to perform closed-loop control of the clamping force of the hydraulic cylinder 603 on the slip block 607. This achieves adaptive adjustment of the clamping force of the slip block 607, ensuring that the slip block 607 provides a constant and reliable clamping force to the drill bit, effectively preventing the drill bit or tool from sliding or tilting in the drill hole.

[0024] Specific uses and functions of this utility model: In this invention, when the slip block 607 adaptively adjusts and clamps the drill string, the drilling operator inputs the clamping force through the human-machine interface 1 (HMI). The HMI sends a clamping command to the PLC device in the hydraulic controller 7 via a wire. The hydraulic controller 7 then controls the oil pump 4 to deliver hydraulic oil from the hydraulic oil station 2 through an oil pipe to the solenoid directional valve 3. The solenoid directional valve 3 then delivers the hydraulic oil through an oil pipe to the diverter valve 5. The diverter valve 5 then distributes the hydraulic oil through four sets of oil pipes to the inlets of four sets of electronic hydraulic pressure gauges 601. Finally, the hydraulic oil is delivered to the hydraulic cylinder 603 via the hydraulic lock 602. The telescopic rods of the four sets of hydraulic cylinders 603 respectively drive the hinged frame 615 at the bottom to move downwards. The hinged frame 615 then drives the connecting rod 614 at the bottom hinge to push the push plate 606 horizontally and centripetally along the groove of the guide plate 605 until the four sets of slip blocks 607 come into contact with each other and are pressed against the outer side of the drill bit. At this time, the drill bit is pressed against the slip blocks 607, and the reaction force generated by the pressure pushes the mounting frame 612. The mounting frame 612 then presses against the pressure sensor 611. The pressure sensor 611 measures the clamping force of the slip blocks 607, and the electronic liquid pressure gauge 601 measures the oil pressure of the hydraulic cylinder 603. When the clamping force reaches the preset value, The electronic liquid pressure gauge 601 and pressure sensor 611 transmit the measured pressure data to the PLC of the hydraulic controller 7 via wires. The control algorithm built into the PLC controls the hydraulic lock 602 to close the oil inlet of the hydraulic cylinder 603 via wires, so that the hydraulic cylinder 603 maintains a stable preset clamping force. When the drill bit vibrates and the clamping force of the slip block 607 loosens, the pressure sensor 611 transmits the measured pressure data to the PLC of the hydraulic controller 7 via wires. The control algorithm built into the PLC controls the hydraulic lock 602 to open the oil inlet of the hydraulic cylinder 603 to inject oil, ensuring the output of the extension rod of the hydraulic cylinder 603. The clamping force remains constant. When it is necessary to release the drill bit, the human-machine interface 1 sends a release command to the PLC device in the hydraulic controller 7 via a wire. The hydraulic controller 7 controls the solenoid directional valve 3 to switch the oil circuit via a wire. The oil pump 4 delivers the hydraulic oil in the cylinder to the hydraulic oil station 2 through the oil pipe. At this time, the telescopic rods of the four sets of hydraulic cylinders 603 respectively drive the hinge frame 615 at the bottom to move upward. The hinge frame 615 then drives the connecting rod 614 at the bottom hinge to pull the push plate 606 to move horizontally and centrifugally along the groove of the guide plate 605 until the four sets of slip blocks 607 disengage from the outer side of the drill bit, thereby completing the release of the drill bit.

[0025] The human-machine interface 1, hydraulic oil station 2, solenoid directional valve 3, oil pump 4, flow divider valve 5, electronic liquid pressure gauge 601, hydraulic lock 602, hydraulic cylinder 603, and pressure sensor 611 mentioned above are all common components on the market. When purchasing and using them, you only need to connect them according to the instruction manual that was purchased with them, so they will not be described in detail here.
