Description

Technical Field

[0001] This invention belongs to the fields of petrochemicals, natural gas, power (nuclear / thermal power), marine engineering, pressure vessels and urban utility tunnel construction technology, and specifically relates to a fully intelligent hole-drilling machine. Background Technology

[0002] In flammable and explosive work scenarios such as petrochemicals, natural gas, power (nuclear / thermal power), marine engineering, pressure vessels, and urban utility tunnel construction, the drilling and emergency repair operations of pipelines, pressure vessels, and storage tanks require strict control. Traditional drilling equipment has many technical defects: First, ordinary drilling machines lack explosion-proof design, and the motors, electrical controls, and switches are prone to generating electric sparks and high temperatures, posing an explosion safety hazard; Second, most equipment lacks remote control functionality, requiring operators to work at close range, facing the risks of leakage and explosion; Third, without servo closed-loop control, the speed and feed accuracy are low, easily leading to problems such as tool jamming, tool breakage, and large hole position deviations, resulting in poor drilling quality consistency; Fourth, the level of intelligence is low, lacking functions such as automatic positioning, adaptive feed, automatic tool retraction, and fault protection, relying on manual operation, resulting in low efficiency and poor stability.

[0003] Currently, there is no existing drilling equipment that integrates wireless remote control, explosion-proof design, servo closed-loop drive, and fully intelligent automatic operation, making it difficult to meet the needs of safe, accurate, and efficient drilling operations in high-risk environments. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a fully intelligent hole-opening machine that enables long-distance safe remote control, explosion-proof spark-free hole opening in flammable and explosive environments, servo high-precision feeding, and fully automatic intelligent operation. This solves the industry pain points of traditional equipment, such as incomplete explosion protection, lack of remote control capability, low precision, weak intelligence, and poor safety.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is a fully intelligent drilling machine, comprising a quick-tensioning base, an explosion-proof lifting actuator, an explosion-proof drilling actuator, a wireless remote control unit, and an explosion-proof control box; the quick-tensioning base includes a tensioning device, a base, a buckle assembly, a chain, and a universal fixing bracket device, with both ends of the chain connected to both ends of the base via the tensioning device and the buckle assembly respectively; the tensioning device adopts a linear transmission mechanism; the buckle assembly includes arc teeth that can be engaged in the gaps between chain links; the universal fixing bracket device includes claws, and a base guide groove is provided below the base, with the top of the claws rotatably mounted in the base guide groove; the base, the explosion-proof lifting actuator, and the explosion-proof drilling actuator are all integrated into the frame assembly; the explosion-proof lifting actuator driver and the explosion-proof drilling actuator driver are integrated into the explosion-proof control box.

[0006] Preferably, the wireless remote control unit includes a wireless remote controller, a wireless receiving module, and a communication module; it has remote one-button automatic operation, forward and reverse rotation control, emergency stop, and data display functions, allowing personnel to remotely operate and monitor the status wirelessly from a safe area.

[0007] Preferably, the explosion-proof lifting actuator includes a lifting body assembly, a rack, a column, a first planetary gear reducer, a first explosion-proof servo motor, and a first encoder; the column is mounted on a base, and a rack is mounted on the column; the lifting body assembly is slidably mounted on the column; the lifting body assembly has a drive shaft inside, and an output gear is mounted on the drive shaft, which meshes with the rack; the output end of the first explosion-proof servo motor is connected to the input shaft of the first planetary gear reducer, and the output end of the first planetary gear reducer is coaxially connected to the drive shaft through a coupling, and the output gear rotates synchronously with the drive shaft; both the first planetary gear reducer and the first explosion-proof servo motor are mounted on the lifting body assembly.

[0008] Preferably, the encoder is coaxially connected to the explosion-proof servo motor to acquire speed and position signals, forming a dual closed-loop control. The planetary gear reducer drives the explosion-proof perforated actuator to achieve precise axial feed.

[0009] Preferably, the tensioning device includes a tensioning screw, a tensioning nut, and a spacer; a base connecting seat is installed at one end of the base, the lower end of the tensioning screw is slidably connected to the base connecting seat, a screw base is provided at the bottom of the tensioning screw, and one end of the chain is installed in the screw base.

[0010] Preferably, there are two chains. The top of the tensioning screw is provided with a Phillips-shaped handle.

[0011] Preferably, the base is provided with a base hole, and the top of the chuck is provided with a chuck hole. A type B pin passes through the base hole and the chuck hole, and the other end of the type B pin is fixed with a cotter pin. The chuck can rotate freely in the base guide groove.

[0012] Preferably, the claw is V-shaped.

[0013] In this invention, the tensioning device adapts to different pipe diameters: one end of the chain is fixed to the tensioning device by a pin, and the other end of the chain is quickly locked between the chain links by a buckle assembly. Rotating the tensioning nut achieves simple and efficient pipe diameter adaptation. Centering clamping: the double chain design allows the base to be center-locked with the pipe to be drilled and eliminates errors caused by pipe ellipticity. Universal fixing bracket: the claws automatically adjust 180° to ensure the base can reliably fit the outer diameter of the pipe. Diameter changing operation: loosening the tensioning nut and disengaging the buckle assembly allows for changing to drilling operations of different pipe diameters. The entire operation is simple and requires no special tools.

[0014] The tensioning device can quickly secure the chain according to different pipe diameters without special tools, ensuring a secure and non-loosening connection. Thanks to its universal mounting structure, it offers the advantage of 180° automatic centripetal adjustment, and replacement is simple – just remove the pin, allowing free movement within the base slot. The screw and nut structure provides smooth and high-precision feeding, while the rubber handle is easy to grip and won't hurt your hands. The base is machined from a single piece of carbon steel plate, offering significantly improved strength and precision compared to aluminum alloy or welded carbon steel plates. The universal mounting's centripetal adjustment is highly efficient and fits tightly to the pipe's outer diameter, reducing the risk of tool breakage and eccentricity during drilling operations.

[0015] Preferably, the explosion-proof hole-opening execution unit includes a second explosion-proof servo motor, a second encoder, a hole opener, and a clamping mechanism. The clamping mechanism is adaptable to fixing pipes or tanks of various specifications, and is convenient to clamp and reliable in positioning, meeting the hole-opening requirements of different working conditions.

[0016] Preferably, it also includes an explosion-proof intelligent control unit, which is installed in an explosion-proof control box and includes a PLC controller, an explosion-proof emergency stop module, and an explosion-proof touch display module. The PLC controller has built-in adaptive feed algorithm, dual closed-loop positioning algorithm, and multi-level fault protection logic, which can adjust the feed speed in real time according to the load to achieve anti-jamming and overload automatic shutdown control; the explosion-proof emergency stop module adopts an intrinsically safe emergency stop button, which immediately cuts off the power output after being triggered to ensure operational safety.

[0017] The working principle of this invention is as follows: The operator sends a work command from a safe area via a wireless remote control. The wireless receiving module inside the explosion-proof electrical control box receives the command and transmits it to the internal explosion-proof intelligent control unit. The explosion-proof intelligent control unit parses the command and drives the explosion-proof drilling execution unit to complete positioning, feeding, drilling, and tool retraction actions via a second explosion-proof servo motor and a second encoder. The sensing and monitoring unit collects work data in real time and feeds it back to the explosion-proof intelligent control unit, forming a dual closed-loop precise control. When overload, over-vibration, or other abnormal conditions occur, the intelligent control unit immediately executes a protective shutdown and simultaneously transmits the work status and fault information back via the wireless remote control unit, achieving fully automatic, high-precision, and high-safety explosion-proof drilling operations.

[0018] The beneficial effects of this invention are as follows: It adopts an explosion-proof structure, and the entire machine complies with GB 3836 series standards. It eliminates electrical sparks, high-temperature surfaces, and static electricity risks, making it suitable for Zone 1 and Zone 2 flammable and explosive hazardous environments. Wireless remote control allows operators to work remotely, away from hazardous sources, significantly improving operational safety. Dual closed-loop control via an explosion-proof servo motor and encoder ensures precise adjustment of speed and feed, resulting in smooth, burr-free hole walls, effectively preventing tool jamming and chipping, and ensuring excellent consistent hole-opening quality. The quick-clamping mechanism is adaptable to workpieces of various diameters, wall thicknesses, and materials, enabling pressurized, non-stop hole-opening operations, suitable for various high-risk working conditions in petroleum, chemical, coal mining, and gas industries. It features automatic centering, automatic positioning, adaptive feed, automatic hole opening, automatic tool retraction, fault diagnosis, and data feedback functions. One-button start completes the entire process, reducing manual labor and increasing work efficiency by over 50%. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0022] Example 1 like Figure 1-10 As shown, a fully intelligent drilling machine includes a quick-tensioning base, an explosion-proof lifting actuator, an explosion-proof drilling actuator, a wireless remote control unit, and an explosion-proof control box 28. The quick-tensioning base includes a tensioning device 2, a base 3, a buckle assembly 5, a chain 1, and a universal fixing bracket device 4. The chain 1 consists of two chains, with both ends connected to the two ends of the base 3 via the tensioning device 2 and the buckle assembly 5, respectively. The tensioning device employs a linear transmission mechanism. The buckle assembly 5 includes arc teeth 501, which can be engaged within the gaps between the chain links of the chain 1. The universal fixing bracket device 4 includes a claw 12. A base guide groove 13 is provided below the base 3, and the top of the claw 12 is rotatably mounted within the base guide groove 13. The claw 12 is generally V-shaped. The base 3, the explosion-proof lifting actuator, and the explosion-proof drilling actuator are all integrated into the frame assembly.

[0023] The tensioning device 2 includes a tensioning screw 10, a tensioning nut 8, and a spacer 9; a base connecting seat 301 is installed at one end of the base, the lower end of the tensioning screw 10 is slidably connected to the base connecting seat, a screw base 101 is provided at the bottom of the tensioning screw 10, and one end of the chain is installed in the screw base 101. A plum blossom rubber handle 11 is provided at the top of the tensioning screw 10.

[0024] By turning the tension nut 8 clockwise to raise the tension screw 10, the chain that is mounted on the pin hole of the screw base 101 via the shaft pin can be tightened.

[0025] The base 3 is provided with a base hole 302, and the top of the claw 12 is provided with a claw hole 503. The B-type pin 502 passes through the base hole 302 and the claw hole 503, and the other end of the B-type pin is fixed with a cotter pin 504. The claw 12 can rotate freely in the base guide groove 13.

[0026] In use, first connect one end of the chain to the screw base 101 of the tensioning device 2. Then, adjust the chain length according to the pipe diameter to adapt to different pipe diameters so that the chain can be engaged with the arc teeth 501 of the buckle assembly 5. In this way, one end of the chain is connected to the pin hole of the tensioning screw base 101 through the pin shaft, and the other end is engaged with the arc teeth 501 of the buckle assembly 5 through the chain joint. By turning the tensioning nut 8 clockwise, the tensioning screw 10 is raised, and the tensioning screw moves to adjust the chain tension. At the same time, the claws 12 in the universal fixing device automatically center and clamp with the pipe 6. The claws 12 of the universal fixing device 4 are connected to the base 3 through the B-type pin 502. The claws 12 can rotate along the B-type pin 502. During the chain tensioning process, the four claws 12 automatically center and clamp the pipe 6, thereby realizing the rapid tensioning and centering of different pipes.

The lifting body assembly 16 has a drive shaft inside, and an output gear is mounted on the drive shaft. The output gear meshes with the rack. The output end of the first explosion-proof servo motor is connected to the input shaft of the first planetary gear reducer. The output end of the first planetary gear reducer is coaxially connected to the drive shaft through a coupling 19, and the output gear rotates synchronously with the drive shaft. The first planetary gear reducer and the first explosion-proof servo motor are both mounted on the lifting body assembly 16.

[0029] The explosion-proof hole-opening execution unit includes a second explosion-proof servo motor 25, a second encoder, a hole opener 27, and a clamping mechanism 26. The clamping mechanism 26 is adaptable to fixing pipes or tanks of various specifications, and is convenient to clamp and reliable in positioning, meeting the hole-opening requirements of different working conditions.

[0030] It also includes an explosion-proof intelligent control unit, which is located inside the explosion-proof control box 28. This unit includes a PLC controller, an explosion-proof emergency stop module, and an explosion-proof touch display module. The PLC controller incorporates an adaptive feed algorithm, a dual closed-loop positioning algorithm, and multi-level fault protection logic. It can adjust the feed speed in real time according to the load, achieving anti-jamming and overload automatic shutdown control. The explosion-proof emergency stop module uses an intrinsically safe emergency stop button, which immediately cuts off the power output upon triggering, ensuring operational safety.

[0031] During use, adjust the tensioning device according to the pipe diameter to firmly fix the base on the pipe to be processed. Next, fix the hole opener into the three-jaw chuck of the quick clamping mechanism according to the hole size. The three-jaw chuck is a universal part, interchangeable with common equipment such as bench drills and radial drilling machines, and is compatible with various drill chucks. Then, place the explosion-proof control box on a flat ground and connect the aviation plugs of the explosion-proof servo motor and explosion-proof proximity switch to the explosion-proof control box. After that, turn on the explosion-proof button 30. Before starting the machine, open the cooling system valve 23. Then, the operator operates the remote control from a safe area. The equipment automatically returns to the origin. Operate the remote control to lift, drill feed, and other operations to achieve remote hole opening. The equipment status is displayed on the remote control screen in real time, completing the fully intelligent hole opening operation.

[0032] The equipment is equipped with stall protection. When stall occurs, the program controls the first explosion-proof servo motor to rotate in both directions to provide protection for the hole opener. When the protection fails, the equipment can be automatically stopped, thus realizing the protection and alarm functions of the equipment.
