Description

Technical Field

[0001] This invention relates to the field of drilling technology for steel pipes in building construction, specifically a drilling device for steel pipes used in building construction. Background Technology

[0002] In recent years, the construction industry has developed rapidly. Construction is a production activity carried out by people using various building materials and machinery and equipment in a certain space and time according to a specific design blueprint to build various building products. It includes the entire production process from construction preparation and groundbreaking to project completion and acceptance. In the construction process, low carbon steel seamless steel pipes with a diameter of 10mm are often used as commonly used steel pipes for fluid and liquid transportation.

[0003] Chinese invention patent CN115846722A discloses a drilling device and method for steel pipes in building construction. The device includes a main frame unit, a drive clamping unit, a drilling unit, and a waste collection unit. The main frame unit includes a base and a connecting plate located directly above the base. The base and the connecting plate are fixedly connected by symmetrically positioned support columns. Symmetrically positioned bent columns are fixedly connected to the side wall of the connecting plate. This drilling device and method for steel pipes in building construction utilizes a first rotating rod that continuously reverses direction. This causes the toothed column to drive the toothed disc to reverse direction, which in turn causes the rotating column to reverse direction. The moving sleeve causes the hinge frame and the moving sleeve to move away from each other, loosening the clamping sleeve and allowing for disassembly of the steel pipe. Simply activating the servo motor automatically completes the limiting, drilling, resetting, and disassembly of the steel pipe, eliminating the need for manual switching of the working state by operators. This reduces the workload of operators and improves the drilling efficiency of steel pipes.

[0004] However, the above-mentioned patent still has the following shortcomings in actual use: Under long-term continuous drilling operation, the temperature of the contact drill rod will gradually rise. The contact drill rod can only cool down naturally when the machine stops. If the stop time is short, the temperature of the contact drill rod will be too high, affecting its drilling work. Summary of the Invention

[0016] Furthermore, the outer wall of the clamping disc is provided with multiple anti-slip grooves.

[0017] This invention provides an improved steel pipe drilling device for building construction, which has the following improvements and advantages compared with the prior art:

[0018] Firstly, this invention uses an electric push rod to move a sliding frame on a horizontal rail. The sliding frame moves a contact block closer to the contact drill rod until one side of the contact block contacts the drill rod. Then, a drive disc drives the contact block to rotate rapidly on the surface of the contact drill rod. The heat on the surface of the contact drill rod is absorbed by the contact block. At the same time, two sets of heat dissipation holes facilitate the airflow generated as the contact block rotates to quickly dissipate heat from the contact block. The heat dissipation component also compresses external gas into the heat dissipation cavity. Then, multiple air blowing holes blow the gas in the heat dissipation cavity onto the surface of the contact drill rod for rapid heat exchange, improving heat dissipation efficiency. Compared with the contact drill rod's natural cooling method when the machine stops, this invention ensures that the contact drill rod is at a relatively low temperature, preventing the drilling operation from being affected by excessively high temperatures, thus facilitating continuous drilling operations.

[0019] Secondly, in this invention, while the drive disc drives the transmission gear to rotate, the transmission gear meshes with the ring rack, causing the transmission shaft to rotate. The transmission shaft then drives the transmission disc to rotate synchronously. The transmission disc uses a hinge rod to drive the push block to reciprocate horizontally a certain distance. In turn, the push block uses a push rod to drive the piston to reciprocate horizontally a certain distance within the air cylinder. When the piston moves forward, it delivers the gas in the air cylinder through the heat dissipation pipe to the heat dissipation cavity, thus supplying gas to the heat dissipation cavity for blowing and heat exchange. When the piston moves backward, it draws external gas into the air cylinder through the air inlet pipe, thus replenishing the gas in the air cylinder. The one-way valve controls the gas in the heat dissipation pipe and the air inlet pipe to flow in only one direction, preventing backflow of gas.

[0020] Thirdly, the present invention uses the clamping component to drive the two clamping frames to move closer to each other, and then the two clamping frames drive the two clamping discs to move closer to each other. The two clamping discs perform abutment clamping operation on both ends of the steel pipe. During the drilling operation, the flipping component uses two flipping shafts to drive the steel pipe to flip, which facilitates the contact drill rod to perform multiple drilling operations on the steel pipe.

Detailed Implementation

[0038] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] This invention provides an improved steel pipe drilling device for building construction, such as... Figures 1-14 As shown, the assembly includes a processing table 1, a steel pipe clamping assembly 2, a moving rail 3, a moving frame 4, a lead screw slide 5, a moving plate 6, a drilling assembly 7, and a cooling mechanism 8. The steel pipe clamping assembly 2 is installed on the top right side of the processing table 1. The moving rail 3 is horizontally positioned on the top left side of the processing table 1. The moving frame 4 is slidably installed on the moving rail 3, and the top of the moving frame 4 has a through hole 41. The lead screw slide 5 is horizontally positioned on the top of the processing table 1. The moving plate 6 is installed on the moving end of the lead screw slide 5 and is connected to the bottom end of the moving frame 4. The drilling assembly 7 is installed on the inner wall of the moving frame 4, and one end of the drilling assembly 7 is located above the steel pipe clamping assembly 2. The cooling mechanism 8... Installed on top of the mobile frame 4, the cooling mechanism 8 cools the drilling assembly 7. The steel pipe to be drilled is placed into the steel pipe clamping assembly 2, which then clamps and limits both ends of the steel pipe. The drilling assembly 7 and the lead screw slide 5 work together to automatically drill the required holes on the steel pipe. The drilling assembly 7 uses two drilling ends to work alternately, while the cooling mechanism 8 cools down one of the idle drilling ends. Compared to the natural cooling method when the machine is stopped, this ensures that the drilling end is at a relatively low temperature, preventing the drilling work from being affected by excessive temperature, and facilitating continuous drilling operations.

[0040] Specifically, the drilling assembly 7 includes a vertical rail 71, a lifting block 72, a support plate 73, a multi-stage push rod 74, an L-shaped frame 75, a bearing plate 76, a switching shaft 77, a switching plate 78, a mounting frame 781, a switching motor 782, a first gear 783, a second gear 784, and two drilling components 79. The vertical rail 71 is vertically mounted on the inner wall of the movable frame 4. The lifting block 72 is slidably mounted on the vertical rail 71. The support plate 73 is mounted on the bottom inner wall of the movable frame 4. The multi-stage push rod 74 is vertically mounted on the top of the support plate 73, and its output end is connected to the lifting block 72. The L-shaped frame 75 is mounted on the outer wall of the lifting block 72. The bearing plate 76 is mounted on the bottom end of the L-shaped frame 75. The switching shaft 77 is rotatably mounted on the top of the bearing plate 76. The switching plate 78 is mounted on the top of the switching shaft 77. The mounting frame 781 is mounted on the outer wall of the switching plate 78. The switching motor 782 is vertically mounted on the top of the bearing plate 76. The first gear 783... 783 is mounted on the output shaft of the switching motor 782, and the second gear 784 is mounted on the switching shaft 77, with the second gear 784 meshing with the first gear 783. Two drilling components 79 are symmetrically arranged in the mounting frame 781, with one drilling component 79 located above the steel pipe clamping assembly 2 and the other drilling component 79 located below the through hole 41. The switching motor 782 drives the first gear 783 and the second gear 784 to rotate the switching shaft 77. The switching shaft 77 drives the mounting frame 781 to rotate 180° via the switching plate 78, thereby realizing the alternating operation of the two drilling components 79. The multi-stage push rod 74 drives the lifting block 72 to move downward on the vertical rail 71. The lifting block 72 drives the L-shaped frame 75 and the two drilling components 79 to move downward, facilitating the drilling operation of one of the drilling components 79 in the working state, while the other drilling component 79 in the idle state is cooled by the cooling mechanism 8.

[0041] Specifically, each drilling component 79 includes a rotating shaft 791, a rotating block 792, a rotary motor 793, a drilling motor 794, a mounting sleeve 795, and a contact drill rod 796. The rotating block 792 is rotatably mounted inside the mounting frame 781 via the rotating shaft 791. The rotary motor 793 is horizontally mounted on the outer wall of the mounting frame 781, and its output shaft is connected to the rotating shaft 791. The drilling motor 794 is vertically mounted at the bottom of the rotating block 792. The mounting sleeve 795 is mounted on the output shaft of the drilling motor 794. The contact drill rod 796... 96 is detachably mounted on the mounting sleeve 795; the rotary motor 793 drives the rotary shaft 791 and the rotary block 792 to rotate, and the rotary block 792 drives the contact drill rod 796 to rotate. When the drilling component 79 is in working condition, the contact drill rod 796 is facing downwards, and when the drilling component 79 is in idle condition, the contact drill rod 796 is facing upwards. The drilling motor 794 drives the mounting sleeve 795 and the contact drill rod 796 to rotate at high speed, and cooperates with the multi-stage push rod 74 and the lead screw slide 5 to perform drilling operations on the steel pipe at the location where drilling is required.

[0042] Specifically, the cooling mechanism 8 includes a fixed frame 81, a hydraulic push rod 811, a descending frame 812, a drive shaft 813, a drive disc 82, a drive motor 83, a drive gear 84, a driven gear 85, a ring rack 86, two contact components 87, two heat dissipation components 88, and four supports 89. The fixed frame 81 is mounted on top of the movable frame 4. The hydraulic push rod 811 is vertically mounted on the top of the fixed frame 81. The descending frame 812 is mounted on the output end of the hydraulic push rod 811. The drive shaft 813 is rotatably mounted on the bottom end of the descending frame 812. The drive disc 82 is mounted on the drive motor 812. At the bottom of shaft 813, drive disk 82 is located above through hole 41. Drive motor 83 is vertically mounted on the inner wall of descending frame 812. Drive gear 84 is mounted on the output shaft of drive motor 83. Driven gear 85 is mounted on the top of drive shaft 813 and meshes with drive gear 84. Four brackets 89 are symmetrically arranged in pairs on the bottom outer wall of descending frame 812. Ring rack 86 is mounted on the bottom of the four brackets 89. Two contact components 87 are symmetrically arranged on the bottom of drive disk 812. Two heat dissipation components 88 are symmetrically arranged on drive disk 813. The top of the two heat dissipation components 88 is connected to the bottom of the two contact components 87 respectively, and the top of the two heat dissipation components 88 is connected to the ring rack 86 for transmission. The hydraulic push rod 811 drives the lowering frame 812 to move downward, and the lowering frame 812 drives the two contact components 87 to move downward. The two contact components 87 move downward to the side of the contact drill rod 796 in the idle and non-working drilling component 79. Then the two contact components 87 move to contact this contact drill rod 796. Then the drive motor 83 drives the drive gear. When gear 84 rotates, the drive gear 84 drives the drive shaft 813 and drive disk 82 to rotate via the driven gear 85. In turn, the drive disk 82 drives the two contact components 87 to rotate. The two contact components 87 rotate on the surface of the contact drill rod 796 to absorb heat. At the same time, the two heat dissipation components 88 also rotate. While rotating, the two heat dissipation components 88 work using the ring rack 86. The two heat dissipation components 88 quickly exchange the heat absorbed by the two contact components 87 to ensure that the heat absorbed by the two contact components 87 is quickly discharged, thus ensuring heat dissipation efficiency.

[0043] Specifically, each contact assembly 87 includes a horizontal rail 871, a sliding frame 872, a contact block 873, and an electric push rod 874. The horizontal rail 871 is horizontally positioned at the bottom of the drive disk 82. The sliding frame 872 is slidably mounted on the horizontal rail 871. The contact block 873 is mounted on the bottom outer wall of the sliding frame 872. The electric push rod 874 is horizontally positioned at the bottom of the drive disk 82, and its output end is connected to the sliding frame 872. Two sets of heat dissipation holes 875 are symmetrically arranged on the outer wall of the contact block 873. A heat dissipation cavity 876 is vertically formed on the contact block 873, and multiple air blowing holes 877 communicating with the heat dissipation cavity 876 are provided on the contact block 873. The operation of the electric push rod 874 drives the sliding frame 872 to move on the horizontal rail 871, and the sliding frame 872 drives the contact block 873 to approach the contact drill rod 796. The contact block 873 moves until one side of the contact drill rod 796 contacts the contact drill rod 796. Then, the drive disk 82 drives the contact block 873 to rotate rapidly on the surface of the contact drill rod 796. The heat on the surface of the contact drill rod 796 is absorbed by the contact block 873. At the same time, the two sets of heat dissipation holes 875 facilitate the airflow generated as the contact block 873 rotates to quickly dissipate heat from the contact block 873. The operation of the heat dissipation component 88 can also compress the external gas into the heat dissipation cavity 876. Then, multiple air blowing holes 877 blow the gas in the heat dissipation cavity 876 onto the surface of the contact drill rod 796 for rapid heat exchange, which improves the heat dissipation efficiency. Compared with the contact drill rod 796 using the method of natural cooling when the machine is stopped, this method ensures that the contact drill rod 796 is at a relatively low temperature and will not affect its drilling operation due to excessive temperature, which is conducive to continuous drilling operations.

[0044] Specifically, each heat dissipation component 88 includes an air cylinder 881, a piston 882, a push rod 883, a push block 884, a drive shaft 885, a drive disc 886, a hinge rod 887, a drive gear 888, a heat dissipation pipe 889, and an air inlet pipe 8891. The air cylinder 881 is horizontally positioned on top of the drive disc 82. The piston 882 is slidably mounted inside the air cylinder 881. The push rod 883 is slidably mounted on the outer wall of the air cylinder 881, and its head end is connected to the piston 882. The push block 884 is mounted on the tail end of the push rod 883. The drive shaft 885... 5. A drive disc 886 is mounted on the top of the drive disc 82. A transmission disc 886 is mounted on the transmission shaft 885. The two ends of the hinge rod 887 are respectively hinged to the top center of the push block 884 and the top edge of the transmission disc 886. A transmission gear 888 is mounted on the top of the transmission shaft 885 and meshes with the ring rack 86. The top end of the heat dissipation pipe 889 is connected to the inside of the air cylinder 881, and the bottom end of the heat dissipation pipe 889 is connected to the heat dissipation cavity 876. An air inlet pipe 8891 is mounted on the outer wall of the air cylinder 881, and the tail end of the air inlet pipe 8891 is connected to the air cylinder 881. The internal parts of cylinder 881 are interconnected, and both the heat dissipation pipe 889 and the air inlet pipe 8891 are equipped with one-way valves 8892. While the drive disc 82 drives the transmission gear 888 to rotate, the transmission gear 888 meshes with the ring rack 86, causing the transmission shaft 885 to rotate. The transmission shaft 885 then drives the transmission disc 886 to rotate synchronously. The transmission disc 886 uses a hinge rod 887 to drive the push block 884 to reciprocate horizontally a certain distance. Furthermore, the push block 884 uses a push rod 883 to drive the piston 882 to reciprocate horizontally within the cylinder 881. When piston 882 moves forward a certain distance, it transports the gas in cylinder 881 through heat dissipation pipe 889 to heat dissipation cavity 876, thus performing gas blowing and heat exchange operation for heat dissipation cavity 876. When piston 882 moves backward, it draws external gas into cylinder 881 through inlet pipe 8891, thus replenishing gas in cylinder 881. One-way valve 8892 controls the gas in heat dissipation pipe 889 and inlet pipe 8891 to flow in only one direction, preventing backflow of gas.

[0045] Specifically, the steel pipe clamping assembly 2 includes a guide rail 21, a flipping component 22, a clamping component 23, two clamping frames 24, two flipping shafts 25, and two clamping discs 26. The guide rail 21 is horizontally positioned on the top right side of the processing table 1. The two clamping frames 24 are symmetrically arranged on the guide rail 21, and the bottom ends of the two clamping frames 24 are slidably engaged with the guide rail 21. The two flipping shafts 25 are rotatably mounted on the top ends of the two clamping frames 24, and the two clamping discs 26 are symmetrically arranged on the two flipping shafts 25. The flipping component 22 is mounted on the top outer wall of one of the clamping frames 24. The flipping component 22 is used to drive one of the flipping shafts 25 to rotate. The clamping component 23 is installed on the processing table 1, and the two ends of the clamping component 23 are respectively connected to the bottom ends of the two clamping frames 24. The operation of the clamping component 23 drives the two clamping frames 24 to move closer to each other, and then the two clamping frames 24 drive the two clamping discs 26 to move closer to each other. The two clamping discs 26 perform abutment clamping operation on both ends of the steel pipe. During the drilling operation, the flipping component 22 uses the two flipping shafts 25 to drive the steel pipe to flip, which facilitates the contact drill rod 796 to perform multiple drilling operations on the steel pipe.

[0046] Specifically, the clamping component 23 includes a clamping motor 231, a clamping gear 232, two connecting frames 233, and two clamping racks 234. The clamping motor 231 is vertically mounted on the top of the processing table 1. The two connecting frames 233 are positioned opposite each other on the bottom outer walls of the two clamping frames 24. The two clamping racks 234 are horizontally mounted on the two connecting frames 233. The clamping gear 232 is mounted on the output shaft of the clamping motor 231, and both sides of the clamping gear 232 mesh with the two clamping racks 234 respectively. The clamping motor 231 drives the clamping gear 232 to rotate. The clamping gear 232 uses the two clamping racks 234 to drive the two connecting frames 233 to move closer to each other, and then the two connecting frames 233 drive the two clamping frames 24 to move closer to each other.

[0047] Specifically, the flipping component 22 includes a flipping motor 221, a third gear 222, and a fourth gear 223. The flipping motor 221 is horizontally mounted on the top outer wall of one of the clamping frames 24. The third gear 222 is mounted on the output shaft of the flipping motor 221, and the fourth gear 223 is mounted on the end of one of the flipping shafts 25, and the fourth gear 223 meshes with the third gear 222. The flipping motor 221 drives the third gear 222 to rotate, and the third gear 222 drives one of the flipping shafts 25 to rotate via the fourth gear 223. This flipping shaft 25 drives the steel pipe and the other flipping shaft 25 to rotate synchronously, which facilitates the contact drill rod 796 to drill multiple holes in the steel pipe.

[0048] Specifically, the outer wall of the clamping disc 26 is provided with multiple anti-slip grooves 261; the anti-slip grooves 261 increase the friction between the clamping disc 26 and the end of the steel pipe, ensuring the stability of clamping the steel pipe.
