Description

Technical Field

[0001] This invention relates to the field of roadbed drainage pipe drilling technology, and in particular to an automated adjustable drilling device for roadbed drainage pipes. Background Technology

[0002] Subgrade drainage is a system designed to prevent and control water damage to the subgrade by intercepting and draining surface water (precipitation and runoff from rain and snow) and groundwater (perched water, phreatic water, and interstitial water). The task of subgrade drainage is to reduce the moisture content of the subgrade soil within the working area to within the allowable range for engineering purposes, ensuring the stable operation of the subgrade. Subgrade drainage pipes effectively solve the problem of water accumulation in subgrade projects during the rainy season or after prolonged soaking, thereby protecting the subgrade and extending its service life. Subgrade drainage pipes are not only an important component of subgrade engineering but also a guarantee of project safety and reliability.

[0003] To ensure efficient roadbed drainage, roadbed drainage pipes are pre-drilled with evenly spaced drainage holes before leaving the factory for sale. However, the drilling process for roadbed drainage pipes has the following drawbacks:

[0004] First, during the drilling operation, the roadbed drainage pipe is placed in place. The motor and chain drive box are used to drive all the drill bits to rotate. The drilling is completed as the cylinder advances. However, the drilling position of the drill bit is either fixed or can only be changed at a fixed distance. In actual operation, it is impossible to adjust the drilling distance according to different gears.

[0005] Secondly, after the roadbed drainage pipes are placed, holes can only be drilled on one side of the roadbed drainage pipes, meaning only one row of holes can be drilled, and multiple rows of holes cannot be drilled. This makes it difficult to meet the requirements for rapid drainage in areas with severe water accumulation.

[0006] In addition, due to the large number of electrical appliances inside the equipment, the space available for personnel to operate is very small. Furthermore, the roadbed drainage pipe is long and has a large outer diameter. After the drilling operation is completed, it will increase the difficulty for the operators to remove the roadbed drainage pipe, making material removal inconvenient and increasing the time spent replacing the roadbed drainage pipe. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides an automated adjustable drilling device for roadbed drainage pipes, which overcomes the deficiencies of existing technologies and effectively solves the problems of not being able to adjust different drilling distances according to different gear levels, not being able to achieve multi-row drilling, and inconvenient material handling.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An automated adjustable drilling device for roadbed drainage pipes includes a punching platform. A first square tube frame is provided on the top outer wall of the punching platform, and symmetrically distributed handles are installed on one side outer wall of the first square tube frame. Adjacent positioning wheels are rotatably connected to the inner walls of the square tubes on both sides of the first square tube frame. Drilling positioning grooves are equally spaced on both sides of the top outer wall of the punching platform, and the positioning wheels are slidably connected to the inner walls of the drilling positioning grooves.

[0010] An angle steel plate is provided on one side of the punching platform, and a roadbed drainage pipe is placed on the inner wall of the angle steel plate. A drive motor is fixedly connected to the bottom outer wall of the angle steel plate by bolts. A long shaft is provided on one side of the drive motor, and anti-slip traction wheels are installed on the outer walls of both ends of the long shaft. A belt drive assembly is installed between the long shaft and the drive motor.

[0011] A second square tube frame is provided at one end of the angle steel plate, and a horizontal cylinder is installed on the inner wall of the top of the second square tube frame. The piston rod of the horizontal cylinder is connected to a horizontal displacement plate, and the outer wall of the horizontal displacement plate is hinged with equally distributed connecting rods. A U-shaped frame is hinged to the outer wall of one end of the connecting rod, and a pulley is rotatably connected to the inner wall of the U-shaped frame. A wedge-shaped feeding plate is rotatably connected to the outer wall of one side of the second square tube frame, and a feeding cylinder is hinged between the wedge-shaped feeding plate and the second square tube frame.

[0012] Preferably, the long shaft is rotatably connected to the bottom outer wall of the angle steel plate, and the anti-slip traction wheel is in close contact with the outer wall of the roadbed drainage pipe.

[0013] Preferably, punching cylinders are installed on the top outer wall of the first square tube frame at equal intervals, and the piston rod of the punching cylinder is connected to a chain drive box. A drilling motor is fixedly connected to one side of the outer wall of the chain drive box at equal intervals by bolts, and drill bits are installed on the other side of the outer wall of the chain drive box at equal intervals.

[0014] Preferably, symmetrically distributed telescopic guide tubes are installed between the chain drive box and the first square tube frame.

[0015] Preferably, guide blocks are welded to the outer walls of both ends of the angle steel plate, and the distance between the guide blocks and the side walls of the angle steel plate is consistent with the outer diameter of the roadbed drainage pipe.

[0016] Preferably, the top outer wall of the angle steel plate is fixedly connected with symmetrically distributed downward pressing cylinders by bolts, and the piston rod of the downward pressing cylinder is connected with a downward pressing plate, which is in close contact with the top outer wall of the roadbed drainage pipe.

[0017] Preferably, the outer walls of the U-shaped frames, which are distributed at equal intervals, are all welded with a central shaft, and the central shaft is rotatably connected to the inner wall of the second square tube frame.

[0018] Preferably, the inclined sidewalls of the wedge-shaped feed plates, which are distributed at equal intervals, are all bonded with rubber patches.

[0019] Preferably, a baffle is welded to one end of the top outer wall of the second square tube frame.

[0020] Preferably, a control cabinet is installed on one outer wall of the first square tube frame, and a control switch is provided on one outer wall of the control cabinet. The control cabinet is connected to the drive motor, horizontal cylinder, feeding cylinder, punching cylinder, drilling motor and pressing cylinder through signal lines.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. The automatic adjustable drilling device for roadbed drainage pipe of the present invention adds a positioning wheel and a drilling positioning groove between the punching table and the first square pipe frame. After the drill bit drills a set of holes on the roadbed drainage pipe, the drilling positioning groove can be used as multiple gears. By pushing the handle, the positioning wheel can be driven to slide in the drilling positioning groove, which can change the horizontal position of the drill bit, thereby realizing the drilling requirement of adjusting the position of the drill bit at different gears and increasing the density between a row of holes.

[0023] 2. The automatic adjustable drilling device for roadbed drainage pipe of the present invention, after a row of holes is drilled in the roadbed drainage pipe, drives the long shaft to rotate through the drive motor. The anti-slip traction wheels at both ends of the long shaft will rotate the roadbed drainage pipe together, changing the drilling position of the roadbed drainage pipe. This allows the holes on the roadbed drainage pipe to be changed from one row to multiple rows. The number of rows of holes can be changed according to the water accumulation in the actual paving area of ​​the customer. In areas with severe water accumulation, it effectively meets the requirements of rapid drainage.

[0024] 3. The automatic adjustable drilling device for roadbed drainage pipes of the present invention allows the operator to push the roadbed drainage pipe onto the second square pipe frame. Utilizing the inclined structure of the second square pipe frame, the roadbed drainage pipe can automatically slide along the pulley. As the piston rod of the horizontal cylinder retracts, the horizontal displacement plate drives the connecting rod to rotate, thereby reducing the height of the U-shaped frame and forcing the roadbed drainage pipe to fall onto the wedge-shaped feeding plate. By retracting the piston rod of the feeding cylinder, one end of the wedge-shaped feeding plate will tilt downwards, realizing the automatic feeding of the roadbed drainage pipe. This reduces the difficulty for the operator to pick up the material, saves time for replacing the roadbed drainage pipe, and improves work efficiency. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Example 1, refer to Figure 1-2 An automated adjustable drilling device for roadbed drainage pipes includes a punching platform 1, a first square tube frame 2 is provided on the top outer wall of the punching platform 1, and symmetrically distributed handles 3 are installed on one side outer wall of the first square tube frame 2. Adjacent positioning wheels 4 are rotatably connected to the inner walls of the square tubes on both sides of the first square tube frame 2, and equally spaced drilling positioning grooves 5 are opened on both sides of the top outer wall of the punching platform 1. The positioning wheels 4 are slidably connected to the inner wall of the drilling positioning grooves 5.

[0034] In this embodiment, a positioning wheel 4 and a drilling positioning groove 5 are added between the punching platform 1 and the first square tube frame 2. After the drill bit 22 has drilled a set of holes on the roadbed drainage pipe, the drilling positioning groove 5 can be used as multiple gears. By pushing the handle 3, the positioning wheel 4 can be driven to slide in the drilling positioning groove 5, which can change the horizontal position of the drill bit 22, thereby realizing the drilling requirement of adjusting the position of the drill bit 22 at different gears and increasing the density between a row of holes.

[0035] Example 2, refer to Figure 4 An automated adjustable drilling device for roadbed drainage pipes is provided. An angle steel plate 6 is provided on one side of the punching platform 1, and a roadbed drainage pipe is placed on the inner wall of the angle steel plate 6. A drive motor 7 is fixedly connected to the bottom outer wall of the angle steel plate 6 by bolts. A long shaft 8 is provided on one side of the drive motor 7, and anti-slip traction wheels 9 are installed on the outer walls of both ends of the long shaft 8. A belt drive assembly 10 is installed between the long shaft 8 and the drive motor 7.

[0036] In this embodiment, after a row of holes is drilled in the roadbed drainage pipe, the drive motor 7 drives the long shaft 8 to rotate. The anti-slip traction wheels 9 at both ends of the long shaft 8 will rotate the roadbed drainage pipe together, changing the drilling position of the roadbed drainage pipe. This allows the holes on the roadbed drainage pipe to be changed from one row to multiple rows. The number of rows of holes can be changed according to the amount of water accumulation in the actual paving area of ​​the customer, effectively meeting the requirements for rapid drainage in areas with severe water accumulation.

[0037] Example 3, refer to Figure 5-6 An automated adjustable drilling device for roadbed drainage pipes is provided. An angle steel plate 6 is provided with a second square tube frame 11 at one end. A horizontal cylinder 12 is installed on the inner wall of the top of the second square tube frame 11. The piston rod of the horizontal cylinder 12 is connected to a horizontal displacement plate 13. The outer wall of the horizontal displacement plate 13 is hinged with equally distributed connecting rods 14. A U-shaped frame 15 is hinged to the outer wall of one end of the connecting rod 14. A pulley 16 is rotatably connected to the inner wall of the U-shaped frame 15. A wedge-shaped feeding plate 17 is rotatably connected to the outer wall of one side of the second square tube frame 11. A feeding cylinder 18 is hinged between the wedge-shaped feeding plate 17 and the second square tube frame 11.

[0038] In this embodiment, the operator can push the roadbed drainage pipe onto the second square pipe frame 11. Utilizing the inclined structure of the second square pipe frame 11, the roadbed drainage pipe can automatically slide along the pulley 16. As the piston rod of the horizontal cylinder 12 contracts, the horizontal displacement plate 13 drives the connecting rod 14 to rotate, thereby reducing the height of the U-shaped frame 15 and forcing the roadbed drainage pipe to fall onto the wedge-shaped feeding plate 17. Utilizing the contraction of the piston rod of the feeding cylinder 18, one end of the wedge-shaped feeding plate 17 will tilt downwards, realizing automatic feeding of the roadbed drainage pipe, reducing the difficulty for the operator to pick up the material, and also saving time for replacing the roadbed drainage pipe, thus improving work efficiency.

[0039] Reference Figure 4 The long shaft 8 is rotatably connected to the bottom outer wall of the angle steel plate 6, and the anti-slip traction wheel 9 is tightly attached to the outer wall of the roadbed drainage pipe.

[0040] Reference Figure 3The top outer wall of the first square tube frame 2 is equipped with punching cylinders 19 that are evenly distributed, and the piston rod of the punching cylinder 19 is connected to a chain drive box 20. One side of the outer wall of the chain drive box 20 is fixedly connected with a punching motor 21 that is evenly distributed, and the other side of the outer wall of the chain drive box 20 is equipped with drill bits 22 that are evenly distributed.

[0041] Reference Figure 3 Symmetrically distributed telescopic guide tubes 23 are installed between the chain drive box 20 and the first square tube frame 2.

[0042] Reference Figure 3-4 Guide blocks 24 are welded to the outer walls of both ends of the angle steel plate 6, and the distance between the guide blocks 24 and the side wall of the angle steel plate 6 is consistent with the outer diameter of the roadbed drainage pipe.

[0043] Reference Figure 3 The top outer wall of the angle steel plate 6 is fixedly connected with symmetrically distributed downward pressing cylinders 25 by bolts, and the piston rod of the downward pressing cylinder 25 is connected with a downward pressing plate 26, which is tightly attached to the top outer wall of the roadbed drainage pipe.

[0044] Reference Figure 6 The outer walls of the U-shaped frames 15, which are distributed at equal intervals, are all welded with a central rod 27, and the central rod 27 is rotatably connected to the inner wall of the second square tube frame 11.

[0045] Reference Figure 5 Rubber stickers 28 are bonded to the inclined side walls of the wedge-shaped feed plates 17, which are distributed at equal intervals.

[0046] Reference Figure 1 A baffle 29 is welded to one end of the top outer wall of the second square tube frame 11.

[0047] Reference Figure 1-6 A control cabinet 30 is installed on one outer wall of the first square tube frame 2, and a control switch is set on one outer wall of the control cabinet 30. The control cabinet 30 is connected to the drive motor 7, the horizontal cylinder 12, the feeding cylinder 18, the punching cylinder 19, the drilling motor 21, and the pressing cylinder 25 via signal lines.

[0048] Working principle: First, the perforated roadbed drainage pipe is slid into the angle steel plate 6 between the guide block 24 and the angle steel plate 6. The lowering cylinder 25 drives the lowering plate 26 to fix the roadbed drainage pipe downward. Then, the punching cylinder 19 drives the drill bit 22 on the other side of the chain drive box 20 to move towards the roadbed drainage pipe. Under the action of the drilling motor 21, the drill bit 22 will complete the drilling operation on one side of the roadbed drainage pipe. Afterward, the handle 3 can be pushed to drive the positioning wheel 4 to slide in the drilling positioning groove 5. The positioning wheel 4 can move into different drilling positioning grooves 5 to change the horizontal position of the drill bit 22. The density between a row of holes can be changed according to actual requirements.

[0049] After a row of holes is drilled in the roadbed drainage pipe, if multiple rows of holes need to be drilled in the roadbed drainage pipe, the drive motor 7 can drive the long shaft 8 to rotate. The anti-slip traction wheels 9 at both ends of the long shaft 8 will rotate the roadbed drainage pipe together. Then, the above-mentioned drilling operation can be performed to complete the requirement of multiple rows of drilling.

[0050] After all the drilling operations are completed, the operator can push the roadbed drainage pipe onto the second square pipe frame 11. Since the second square pipe frame 11 is inclined, the roadbed drainage pipe can automatically slide along the pulley 16 to one side of the baffle 29. At this time, the piston rod of the retracting horizontal cylinder 12 will control the horizontal displacement plate 13 to drive the connecting rod 14 to rotate, thereby reducing the height of the U-shaped frame 15 and forcing the roadbed drainage pipe to fall onto the wedge-shaped feeding plate 17. Finally, by retracting the piston rod of the feeding cylinder 18, one end of the wedge-shaped feeding plate 17 will tilt downward, and the roadbed drainage pipe will automatically roll onto the ground along the wedge-shaped feeding plate 17.
