With the continuous advancement of global infrastructure construction, especially against the backdrop of accelerated urbanization and a surge in demand for the renovation of aging pipe networks, the market demand for drainage pipes is experiencing rapid growth. According to relevant data forecasts, the global drainage pipe market size will climb from approximately US$58 billion to US$82 billion between 2025 and 2030, with a compound annual growth rate of 4.8%. China, as the world's largest producer and consumer of drainage pipes, will account for over 35% of the market. Such a massive market demand places higher demands on the production efficiency and quality of drainage pipes.
[0003] Existing drainage pipe drilling devices can only drill from one side and require a flipping mechanism to flip the drainage pipe for drilling from all sides, resulting in low efficiency. Furthermore, the drilling process generates a large amount of debris, and existing equipment lacks effective debris removal measures. The debris easily accumulates on the workbench or enters the inside of the pipe, making cleaning difficult. Therefore, a new drilling device for drainage pipe production is needed to solve the above problems. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0024] Please see Figure 1-4 A drilling device for producing drainage pipes includes an L-shaped base frame 1, with a double-sided drilling device and a chip removal device installed above the L-shaped base frame 1.
[0025] The double-sided drilling device includes mounting plates 11 fixedly connected to the front and rear ends of an L-shaped base frame 1. First electric actuators 12 are mounted on the outer walls of both mounting plates 11. A horizontal plate 13 is fixedly connected to the output end of each first electric actuator 12. Multiple evenly distributed drilling shafts 14 are rotatably connected to the outer wall of the horizontal plate 13. Gears 15 are fixedly connected to the outer walls of each drilling shaft 14, and adjacent gears 15 mesh with each other.
[0026] The chip removal device includes a second electric push rod 2 installed at the right end of the L-shaped base frame 1. The output end of the second electric push rod 2 passes through the L-shaped base frame 1 and is fixedly connected to a frame 3. A hollow disc 5 is provided at the left end of the frame 3. A fan 6 is installed through the right end of the disc 5. A housing 7 is fixedly connected to the left end of the L-shaped base frame 1. A support shaft 8 is rotatably connected inside the housing 7. A limit frame 9 is fixedly connected to the right end of the support shaft 8. A collection bin 10 is provided at the lower end of the housing 7.
[0027] In this embodiment: the first electric actuators 12 mounted on the mounting plates 11 at both ends are started synchronously, pushing the horizontal plate 13 closer to the drain pipe. When the drilling shaft 14 contacts the surface of the pipe, the first motor 16 is started. The output end of the first motor 16 drives the drilling shaft 14 connected to it to rotate. Through the meshing transmission of adjacent gears 15, multiple drilling shafts 14 rotate synchronously. At the same time, the first electric actuators 12 continuously apply thrust to realize synchronous drilling on both sides of the drain pipe.
[0028] During drilling, the chip removal device operates simultaneously. The fan 6 at the right end of the disc 5 starts, and the airflow generated enters the drain pipe through the internal hollow structure from the ventilation mesh plate 18 at the left end, pushing the drilling debris to the left. After the debris enters the housing 7 with the airflow, it falls into the collection chamber 10 at the lower end under the action of gravity, completing the centralized collection of debris.
[0029] As a technical optimization of this utility model, a first motor 16 with its output end fixedly connected to one of the drilling shafts 14 is installed on the outer wall of the horizontal plate 13.
[0030] In this embodiment, the first motor 16 can drive the drill shaft 14 connected to it to rotate.
[0031] As a technical optimization of this utility model, a second motor 4 is installed inside the frame 3, and the output end of the second motor 4 passes through the frame 3 and is fixedly connected to the disk 5.
[0032] In this embodiment, the second motor 4 can drive the disk 5 to rotate.
[0033] As a technical optimization of this utility model, a ventilation mesh plate 18 is installed through the left end of the disc 5.
[0034] In this embodiment, the ventilation mesh 18 allows airflow to pass smoothly into the interior of the drain pipe, providing power for pushing debris.
[0035] As a technical optimization of this utility model, a circular groove 19 is provided through the right end of the shell 7, and the limiting frame 9 is fitted with the inner wall of the circular groove 19.
[0036] In this embodiment, the limiting frame 9, by closely fitting the inner wall of the circular groove 19, can limit the shaking of itself and the connected components, ensuring that the left end of the drain pipe is stable during the drilling process and avoiding deviation in the drilling position due to pipe offset.
[0037] As a technical optimization of this utility model, a support platform 17 is fixedly connected to the upper end of the L-shaped base frame 1.
[0038] In this embodiment, the support platform 17 can conveniently support the drain pipe.
[0039] As a technical optimization of this utility model, the lower end of the frame 3 is fixedly connected to an auxiliary plate 20 that fits against the upper end of the L-shaped base frame 1.
[0040] In this embodiment, the stability of the frame 3 movement can be increased by the auxiliary plate 20.
[0041] The working principle and usage process of this utility model are as follows: Before drilling, the drainage pipe to be processed is placed on the support platform 17, with its left end abutting against the limit frame 9. Then, the second electric push rod 2 is activated, and its output end pushes the frame 3 to move to the left. The auxiliary plate 20 at the lower end of the frame 3 ensures the stability of the movement process until the disc 5 is tightly attached to the right end of the drainage pipe, thus completing the fixing of the drainage pipe.
[0042] During the drilling stage, the double-sided drilling device begins operation. The first electric actuators 12, mounted on the mounting plates 11 at both ends, start synchronously, pushing the horizontal plate 13 towards the drain pipe. When the drilling shaft 14 contacts the pipe surface, the first motor 16 is started. The motor output drives the drilling shaft 14 connected to it to rotate. Through the meshing transmission of adjacent gears 15, multiple drilling shafts 14 rotate synchronously, while the first electric actuators 12 continuously apply thrust, achieving synchronous drilling on both sides of the drain pipe.
[0043] During drilling, the chip removal device operates simultaneously. The fan 6 at the right end of the disc 5 starts, and the airflow generated enters the drain pipe through the internal hollow structure from the ventilation mesh plate 18 at the left end, pushing the drilling debris to the left. After the debris enters the housing 7 with the airflow, it falls into the collection chamber 10 at the lower end under the action of gravity, completing the centralized collection of debris.
[0044] If the drilling position needs to be adjusted, the second motor 4 inside the frame 3 drives the disc 5 to rotate, and the drain pipe, support shaft 8 and limit frame 9 rotate, thereby adjusting the angle of the drain pipe. Combined with the uniform distribution characteristics of the drilling shaft 14, precise drilling at different positions is achieved, improving the efficiency and quality of drain pipe drilling.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0046] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
