Description

Technical Field

[0001] The invention relates to the technical field of prefabricated product processing, and in particular to a drilling device for producing cement prefabricated products. Background Art

[0002] Cement prefabricated products refer to components or materials manufactured in factories or production sites by using cement and other appropriate materials in accordance with certain processes and standard specifications. These components or materials undergo special processing and maintenance during the manufacturing process to ensure that their quality and performance meet the pre-set requirements. Cement prefabricated products usually include components of various shapes and uses, such as prestressed concrete components, concrete pipes, concrete slabs, concrete bricks, concrete beams, etc. They are widely used in various fields such as construction, roads, bridges, tunnels, and water conservancy projects. The manufacturing process of cement prefabricated products includes the selection of raw materials, ratio design, mixing, molding, and maintenance. The manufacturing process strictly follows relevant technical standards and specifications to ensure the strength, durability, stability, and safety of the products. The advantages of cement prefabricated products include simple production process, controllable quality, convenient construction, and shortened construction period. They can improve the efficiency and quality of construction projects while reducing reliance on on-site construction, lowering construction risks and costs. However, during the production process of cement prefabricated products, drilling is required on the prefabricated products for technical needs such as installing and fixing accessories, drainage or ventilation, enhancing the structure and testing quality. When using them, on-site drilling is required based on actual applications.

[0003] A drilling device for cement prefabricated product production is disclosed in the patent with announcement number CN212795455U, including a main body, and a connecting rod is arranged at the bottom of the main body. By setting a fixed ring, a rebound device, a movable hole, a through hole, a fixing device, a push rod, a pressure plate and a transparent shell for coordinated use, after picking up the fixed ring to contact with the connecting rod and drive the clamping to move into the clamping groove, the pressure plate is released, and the second spring undergoes elastic deformation to drive the moving plate back to its original position, and the moving plate moves to drive the fixing rod to pass through the perforation to the fixing hole, completing the protection of the rotating head, after picking up the fixed ring to contact with the connecting rod and drive the clamping block to move into the clamping groove, the pressure plate is released, and the second spring undergoes elastic deformation to drive the moving plate back to its original position, and the moving plate moves to drive the fixing rod to pass through the perforation to the fixing hole, completing the protection of the rotating head;

[0004] The above-mentioned related technology has the following defects: the drilling device can only open small holes and it is difficult to open large holes. For example, when the small drill bit is replaced with a large drill barrel, it is difficult to achieve uniform cooling treatment inside the drill barrel to prevent the drill barrel from deforming due to high temperature, and the drilled cylindrical cement blocks are easily stuck inside the drill barrel, which is inconvenient to handle.

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Example: See Figure 1-Figure 5 , a drilling device for cement prefabricated product production, comprising a support frame 1 and a workbench 2, and also comprising:

[0035] A positioning mechanism is installed on the support frame 1 and is located above the workbench 2, and is used to fix the preform on the top of the workbench 2. The positioning mechanism includes a first transmission shaft 3 rotatably connected to the inside of the support frame 1, a first reciprocating screw 4 fixedly sleeved on the outside of the first transmission shaft 3, a lifting plate 5 screwed on the outside of the first reciprocating screw 4, and two lower pressing seats 6 fixedly connected to the bottom of the lifting plate 5. A through groove is opened inside the lifting plate 5. A guide rod 7 is fixedly connected to the top of the workbench 2. The lifting plate 5 is also slidably sleeved on the outside of the guide rod 7. The first transmission shaft 3 is connected to the driving mechanism;

[0036] The first transmission shaft 3 is driven to rotate by the driving mechanism, and the first transmission shaft 3 drives the first reciprocating screw 4 fixedly sleeved on the outside thereof to rotate synchronously during the rotation process, thereby driving the lifting plate 5 to move down from the top of the first reciprocating screw 4 to the bottom thereof. In this process, the two lower pressing seats 6 are driven to move downward synchronously, and the cement precast panel is fixed on the top of the workbench 2, so as to prevent the cement precast panel from moving during the drilling process, thereby effectively improving the stability of the cement precast panel during the drilling process;

[0037] After the drilling is completed, the first transmission shaft 3 continues to be driven to rotate through the driving mechanism. During the rotation process, the first transmission shaft 3 drives the first reciprocating screw 4 fixedly sleeved on the outside thereof to rotate synchronously, thereby driving the lifting plate 5 to move from the bottom end of the first reciprocating screw 4 to the top end thereof. In this process, the two lower pressure seats 6 are driven to move upward synchronously to release the fixation of the cement prefabricated product.

[0038] A drilling mechanism is arranged above the workbench 2 and is used to drill holes in the fixed preform. The drilling mechanism includes a drill tube 8 (existing technology), a second transmission shaft 9 fixed to the top of the drill tube 8, and a sleeve 10 slidably sleeved on the outside of the second transmission shaft 9. The sleeve 10 is rotatably connected to the inside of the support frame 1, the drill tube 8 is located on the inner side of the through groove, and the sleeve 10 is connected to the driving mechanism.

[0039] The shaft sleeve 10 is driven to rotate by the driving mechanism, and the second transmission shaft 9 slidingly connected inside the shaft sleeve 10 rotates synchronously therewith, thereby driving the drill tube 8 to rotate. The drill tube 8 in the rotating process can perform drilling processing on the cement prefabricated product.

[0040] A lifting mechanism, which is connected to the drilling mechanism and is used to drive the drilling mechanism to move, the lifting mechanism includes a third transmission shaft 11 rotatably connected to the inner wall of the top of the support frame 1, a second reciprocating screw 12 fixedly sleeved on the outside of the third transmission shaft 11, a connecting block 13 screwed on the outside of the second reciprocating screw 12, and a connecting sleeve 14 rotatably connected to the inside of the connecting block 13, the connecting sleeve 14 is fixedly sleeved on the outside of the second transmission shaft 9, and the lifting mechanism also includes two first gears 15 fixedly sleeved on the outside of the third transmission shaft 11 and the outside of the sleeve 10, respectively, and the two first gears 15 are meshed with each other;

[0041] When the drive mechanism drives the sleeve 10 to rotate, the first gear 15 on the outside of the sleeve 10 rotates synchronously, and the meshing action between the two first gears 15 drives the third transmission shaft 11 to rotate, and the second reciprocating screw 12 fixedly sleeved on the outside of the third transmission shaft 11 rotates synchronously, thereby driving the connecting block 13 to move from the top end of the second reciprocating screw 12 to its bottom end, and then driving the connecting block 13 to move from the bottom end of the second reciprocating screw 12 to its top end;

[0042] When the connecting block 13 moves downward from the top end to the bottom end of the second reciprocating screw 12, the second transmission shaft 9 is driven to move downward synchronously through the connecting sleeve 14, thereby driving the drill tube 8 in the rotating process to move downward synchronously and slowly, so as to perform drilling processing on the cement prefabricated product;

[0043] When the connecting block 13 moves from the bottom end of the second reciprocating screw 12 to the top end thereof, the second transmission shaft 9 is driven to move upward synchronously through the connecting sleeve 14, and then the drill tube 8 is driven to move upward synchronously and reset to prepare for the next drilling work.

[0044] A dust reduction and cooling mechanism is arranged inside the drilling mechanism, and is used to reduce the amount of dust generated during the drilling process and to cool the drilling mechanism. The dust reduction and cooling mechanism includes a cooling water pipe 19 installed inside the fixed shaft 17 and a plurality of nozzles 20 installed at one end of the cooling water pipe 19. The other end of the cooling water pipe 19 is connected to a supply device, and the plurality of nozzles 20 are all located inside the drill tube 8.

[0045] When drilling, coolant is injected into the cooling water pipe 19 through the supply device, and the coolant in the cooling water pipe 19 is then sprayed out through multiple nozzles 20, and the coolant is then sprayed onto the inner wall of the drill barrel 8. Since the drill barrel 8 is rotating, the coolant can be evenly sprayed onto the inner wall of the drill barrel 8, and the drill barrel 8 is evenly cooled. The outflowing coolant can effectively reduce the dust generated by drilling, effectively reducing the dust raised and reducing the impact on the working environment.

[0046] The discharge mechanism is arranged on the inner side of the drilling mechanism and is used to discharge the cement blocks drilled out of the drilling mechanism. The discharge mechanism includes a fixing frame 16 installed on the top of the support frame 1, a fixing shaft 17 fixed to the fixing frame 16, and a discharge block 18 fixed to the bottom end of the fixing shaft 17. The sleeve 10, the second transmission shaft 9 and the drill tube 8 are all sleeved on the outside of the fixing shaft 17, and the discharge block 18 is located on the inner side of the drill tube 8.

[0047] The fixed shaft 17 and the discharge block 18 remain stationary at all times, and when the drill tube 8 is driven to move downward, the drilled cylindrical cement block enters the drill tube 8 and is located below the discharge block 18;

[0048] When the drill tube 8 is driven to move upward, the discharge block 18 automatically pushes out the cylindrical cement block inside the drill tube 8 to separate it from the drill tube 8, thereby solving the problem that the drilled cylindrical cement block is easily stuck inside the drill tube 8.

[0049] A driving mechanism, which is installed on the top of the support frame 1, and is used to drive the positioning mechanism and the drilling mechanism to operate respectively. The driving mechanism includes a motor 21 installed inside the support frame 1, a second gear 22 fixedly sleeved on the outside of the output shaft of the motor 21, and a first one-way gear 23 installed on the outside of the first transmission shaft 3, and the first one-way gear 23 is meshed with the second gear 22;

[0050] The second gear 22 is driven to rotate forward by controlling the motor 21, and the first transmission shaft 3 is driven to rotate through the meshing effect between the second gear 22 and the first one-way gear 23. At this time, the second one-way gear 24 also rotates, but the sleeve 10 does not rotate.

[0051] The driving mechanism further includes a second one-way gear 24 mounted on the outside of the sleeve 10, and the second one-way gear 24 is meshed with the second gear 22;

[0052] The second gear 22 is driven to reverse by controlling the motor 21, and the second gear 22 is meshed with the second one-way gear 24 to drive the sleeve 10 to rotate. At this time, the first one-way gear 23 also rotates, but the first transmission shaft 3 does not rotate.

[0053] Working principle: When in use, first place the cement prefabricated product to be processed on the top of the workbench 2, and by adjusting the position of the cement prefabricated product, determine that the position of the drill hole is directly below the drill tube 8, and then, by controlling the motor 21 to drive the second gear 22 to rotate forward, the second gear 22 is meshed with the first one-way gear 23 to drive the first transmission shaft 3 to rotate, and the first transmission shaft 3 drives the first reciprocating screw 4 fixedly sleeved on the outside thereof to rotate synchronously during the rotation process, thereby driving the lifting plate 5 to move down from the top of the first reciprocating screw 4 to its bottom end. In this process, the two lower pressure seats 6 are driven to move downward synchronously to fix the cement prefabricated plate on the top of the workbench 2, preventing the cement prefabricated plate from The problem of the plate moving during the drilling process is solved, which effectively improves the stability of the cement precast plate during the drilling process, and then drives the second gear 22 to reverse by controlling the motor 21, and drives the sleeve 10 to rotate through the meshing effect between the second gear 22 and the second one-way gear 24, and the second transmission shaft 9 slidingly connected to the inside of the sleeve 10 rotates synchronously, thereby driving the drill tube 8 to rotate, and the first gear 15 outside the sleeve 10 rotates synchronously, and the meshing effect between the two first gears 15 drives the third transmission shaft 11 to rotate, and the second reciprocating screw 12 fixedly sleeved on the outside of the third transmission shaft 11 rotates synchronously, thereby driving the connecting block 13 to move from the top end of the second reciprocating screw 12 to its bottom end;

[0054] In this process, the second transmission shaft 9 is driven to move downward synchronously through the connecting sleeve 14, and then the drill tube 8 in the rotating process is driven to move downward synchronously and slowly, so as to perform drilling processing on the cement prefabricated product. When drilling, the coolant is injected into the cooling water pipe 19 through the supply device, and the coolant in the cooling water pipe 19 is then sprayed out through multiple nozzles 20, and the coolant is then sprayed onto the inner wall of the drill tube 8. Since the drill tube 8 is rotating, the coolant can be evenly sprayed onto the inner wall of the drill tube 8, and the drill tube 8 is evenly cooled. The outflowing coolant can well reduce the dust generated by drilling, effectively reducing the dust raised and reducing the impact on the working environment.

[0055] In addition, when the drill barrel 8 is driven to move downward, the drilled cylindrical cement block enters the drill barrel 8 and is located below the discharge block 18. After the drilling is completed, the driving mechanism continues to drive the sleeve 10, the third transmission shaft 11, and the second reciprocating screw 12 to rotate, and the connecting block 13 moves from the bottom end of the second reciprocating screw 12 to its top. In this process, the second transmission shaft 9 is driven to move upward synchronously through the connecting sleeve 14, and then the drill barrel 8 is driven to move upward and reset synchronously. When the drill barrel 8 is driven to move upward, the discharge block 18 automatically pushes out the cylindrical cement block inside the drill barrel 8, so that it is separated from the drill barrel 8, solving the problem that the drilled cylindrical cement block is easily stuck in the drill barrel 8. Finally, the driving mechanism continues to drive the first transmission shaft 3 to rotate. During the rotation process, the first transmission shaft 3 drives the first reciprocating screw 4 fixedly sleeved on the outside to rotate synchronously, and then drives the lifting plate 5 to move from the bottom end of the first reciprocating screw 4 to its top. In this process, the two lower pressure seats 6 are driven to move upward synchronously to release the fixation of the cement prefabricated product.
