Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, and in particular to a drilling device for municipal construction. Background Technology

[0002] Drilling is a common basic procedure in municipal engineering construction, and it is widely used in roadbed reinforcement, underground pipeline installation and positioning, and traffic facility foundation construction (such as cement, asphalt, and brickwork).

[0003] A drilling device for road and bridge municipal construction is disclosed in Chinese utility model patent with announcement number CN222207804U, including: a base plate, a support frame fixedly installed on the top of the base plate, a power component set on the top of the support frame, a motor set on one side of the power component, a drill bit connected to the output end of the motor, a threaded rod, the threaded rod being threadedly connected to one side of the support frame, a turning block fixedly installed on one end of the threaded rod, a moving block connected to the end of the threaded rod away from the turning block through a bearing, and a brush set on one side of the moving block.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: In the aforementioned device, rotating the screw block can drive the threaded rod to rotate, allowing the moving block to slide on one side of the support frame via the slide rod, thereby enabling the brush to work in conjunction with the rotation of the drill bit to brush off the debris on the surface of the drill bit. However, if the device is applied to a high-humidity environment, when the drill bit is drilling, highly viscous debris will adhere to the surface, reducing the cleaning efficiency of the brush. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a drilling device for municipal construction.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a municipal construction drilling device, including a base plate, a U-shaped mounting frame fixed to the top of the base plate, a sliding plate slidably arranged between the frame bodies on both sides of the U-shaped mounting frame, a rotating rod rotatably mounted on the sliding plate, a auger blade fixedly sleeved on the rotating rod, a power motor for driving the rotating rod to rotate fixed to the top of the sliding plate, a driving component for driving the sliding plate to move on the U-shaped mounting frame, a positioning rod on the U-shaped mounting frame, a sleeve fixed to the side wall of the positioning rod near the auger blade, an upper clamping block and a lower clamping block arranged inside the sleeve, a transmission component for driving the upper clamping block and the lower clamping block to clamp the auger blade inside the sleeve, and a moving component for driving the positioning rod to move on the base plate.

[0007] By adopting the above technical solution, when workers need to drill holes in roads with high soil moisture, they first use a moving component to drive a positioning rod towards the auger blade, which in turn moves the upper and lower clamping blocks. Then, a transmission component drives the upper and lower clamping blocks to move closer together, clamping the auger blade. Simultaneously, the worker starts a power motor, which rotates the auger blade. The worker then controls a drive component to move a sliding plate, which in turn moves the auger blade to drill. During drilling, the worker lifts the auger blade using the drive component, and simultaneously uses the clamping action of the upper and lower clamping blocks to remove sticky debris from the blade. This application changes the traditional brush-based cleaning method, improving cleaning efficiency.

[0008] Furthermore, the transmission assembly includes an upper connecting rod fixed to the side of the upper clamping block away from the auger blade, an upper rack fixed to the bottom of the upper connecting rod, a lower connecting rod fixed to the side of the lower clamping block away from the auger blade, a lower rack fixed to the top of the lower connecting rod, a transmission rod rotatably installed in the sleeve, and a gear fixedly sleeved on the transmission rod and meshing with both the upper and lower racks. The transmission rod passes through the side wall of one side of the sleeve and is rotatably connected to the sleeve. A handwheel is fixed to the side of the transmission rod away from the sleeve. The upper and lower racks are staggered about the gear.

[0009] By adopting the above technical solution, the operator rotates the handwheel, which drives the transmission rod and the gear fixed to the transmission rod to rotate. Since the upper and lower racks are both meshed with the gear, and the upper and lower racks are staggered about the gear, the gear drives the upper and lower racks to move. The upper rack drives the upper clamping block to move, and the lower rack drives the lower clamping block to move, so that the upper and lower clamping blocks move closer to each other, thereby clamping the auger blades.

[0010] Furthermore, an upper limit rod is provided on the side wall of the upper rack away from the lower rack, and an upper sliding groove is provided inside the sleeve for the upper limit rod to slide. A lower limit rod is provided on the side wall of the lower rack away from the upper rack, and a lower sliding groove is provided inside the sleeve for the lower limit rod to slide.

[0011] By adopting the above technical solution, the setting of the upper and lower limit rods prevents the upper and lower racks from shifting during movement, thus ensuring the efficiency of transmission.

[0012] Furthermore, the handwheel has a through hole, and a rod is inserted into the through hole. The sleeve has a socket on the side near the handwheel for inserting the rod. There are multiple sockets arranged in a circular array.

[0013] By adopting the above technical solution, when the upper and lower clamping blocks clamp the auger blades, the staff will pass the insertion rod through the through hole and then insert the insertion rod into the insertion hole. The insertion rod limits the movement of the upper and lower clamping blocks to prevent them from loosening during the rotation of the auger blades.

[0014] Furthermore, the movable component includes a fixed plate fixed to the top of the base plate, a lead screw rotatably mounted between the fixed plate and the U-shaped mounting bracket, a sliding block sleeved on the lead screw and threadedly connected to the lead screw, a guide rod fixed between the fixed plate and the U-shaped mounting bracket and parallel to the lead screw, and a drive motor fixed to the side of the fixed plate away from the U-shaped mounting bracket. The guide rod passes through the sliding block and slides with it. The end of the lead screw away from the U-shaped mounting bracket passes through the fixed plate and is fixed to the output end of the drive motor. The top of the sliding block is connected to the bottom of the positioning rod. An opening is provided on one side wall of the U-shaped mounting bracket for the positioning rod to pass through.

[0015] By adopting the above technical solution, the staff controls the drive motor, the drive motor starts and drives the lead screw to rotate. Since the sliding block is threadedly connected to the lead screw and the guide rod passes through the sliding block, the sliding block moves along the axis of the lead screw, thereby causing the sliding block to drive the positioning rod to move, and the positioning rod to drive the upper clamping block and the lower clamping block to move.

[0016] Furthermore, the positioning rod has a through mounting hole, the sliding block has a positioning hole corresponding to the mounting hole, the sliding block has a fixing hole communicating with the positioning hole, a long rod is provided in both the mounting hole and the positioning hole, and a bolt threadedly connected to the long rod is provided in the fixing hole.

[0017] By adopting the above technical solution, when there are sticky foreign objects in the upper and lower clamping blocks, the workers can loosen and remove the bolts with tools, and then remove the long rod. The positioning rod, transmission assembly, and upper and lower clamping blocks can then be disassembled as a whole. After disassembly, the workers can clean the foreign objects from the upper and lower clamping blocks, and then install the positioning rod, transmission assembly, and upper and lower clamping blocks onto the sliding block using the long rod and bolts.

[0018] Furthermore, a limiting plate is fixed on the positioning rod, and the limiting plate abuts against the inner wall of the opening.

[0019] By adopting the above technical solution, the setting of the limiting plate prevents the rotation of the auger blade from damaging the screw thread when the upper and lower clamping blocks clamp the auger blade, thus ensuring the transmission accuracy and service life of the screw.

[0020] Furthermore, the drive assembly includes a connecting plate fixed to the top of the sliding plate, a mounting plate fixed to the top of the connecting plate, and an upper electric push rod disposed on the top of the U-shaped mounting bracket and driving the mounting plate to move.

[0021] By adopting the above technical solution, the staff controls the upper electric push rod, which starts and drives the mounting plate fixed to it, the connecting plate fixed to the mounting plate, and the sliding plate fixed to the connecting plate to move, thereby causing the sliding plate to drive the auger blade to drill holes.

[0022] Furthermore, an upper rubber pad is fixed to the bottom of the upper clamping block, and a lower rubber pad is fixed to the top of the lower clamping block.

[0023] By adopting the above technical solution, the upper and lower rubber pads are made of rubber, which has a certain degree of flexibility and resilience. When the upper and lower clamping blocks clamp the auger blades, the upper and lower rubber pads fit the auger blades more closely, ensuring cleaning efficiency.

[0024] In summary, this utility model has the following beneficial effects: When workers need to drill holes in roads with high soil moisture, they first use the moving component to drive the positioning rod towards the auger blade, thereby causing the positioning rod to move the upper and lower clamping blocks. Then, the transmission component drives the upper and lower clamping blocks to move towards each other, thereby clamping the auger blade. At the same time, the workers control the start of the power motor, which drives the auger blade to rotate. The workers then control the drive component to drive the sliding plate to move, which drives the auger blade to drill holes. During the drilling process, the workers lift the auger blade using the drive component, and at the same time, use the mutual clamping of the upper and lower clamping blocks to clean the sticky debris from the auger blade.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figure 1-9 As shown in the embodiment of this application, a municipal construction drilling device is disclosed, including a base plate 1, a U-shaped mounting frame 11, a sliding plate 12, a rotating rod 13, a auger blade 14, a power motor 15, a drive assembly 2, a positioning rod 16, a sleeve 17, an upper clamping block 18, a lower clamping block 19, a transmission assembly 3, and a moving assembly 4. The U-shaped mounting frame 11 is fixed to the top of the base plate 1, and the U-shaped mounting frame 11 is U-shaped. The sliding plate 12 is slidably disposed between the frame bodies on both sides of the U-shaped mounting frame 11, and the rotating rod 13 is rotatably mounted on the sliding plate 12. The auger blade 14 is fixedly sleeved on the rotating rod 13, and the axis of the auger blade 14 coincides with the axis of the rotating rod 13. The power motor 15 is fixed to the top of the sliding plate 12, and the power motor 15 is used to drive the rotating rod 13 to rotate.

[0029] The drive assembly 2 is mounted on the U-shaped mounting bracket 11 and is used to drive the sliding plate 12 to move. The drive assembly 2 includes a connecting plate 21, a mounting plate 22, and an upper electric push rod 23. The connecting plate 21 is fixed to the top of the sliding plate 12, and the mounting plate 22 is fixed to the top of the connecting plate 21. The upper electric push rod 23 is mounted on the top of the U-shaped mounting bracket 11 and is used to drive the mounting plate 22 to move. The positioning rod 16 is mounted on the U-shaped mounting bracket 11, and the sleeve 17 is fixed to the side wall of the positioning rod 16 near the auger blade 14. The upper clamping block 18 and the lower clamping block 19 are located inside the sleeve 17.

[0030] The transmission assembly 3 is disposed within the sleeve 17 and is used to drive the upper clamping block 18 and the lower clamping block 19 to clamp the auger blade 14. The transmission assembly 3 includes an upper connecting rod 31, an upper rack 32, a lower connecting rod 33, a lower rack 34, a transmission rod 35, and a gear 36. The upper connecting rod 31 is fixed to the side of the upper clamping block 18 away from the auger blade 14, and the upper rack 32 is fixed to the bottom of the upper connecting rod 31. The lower connecting rod 33 is fixed to the side of the lower clamping block 19 away from the auger blade 14, and the lower rack 34 is fixed to the top of the lower connecting rod 33. The transmission rod 35 is rotatably mounted within the sleeve 17, and the gear 36 is fixedly sleeved on the transmission rod 35 and meshes with both the upper rack 32 and the lower rack 34. In this embodiment, the transmission rod 35 passes through one side wall of the sleeve 17 and is rotatably connected to the sleeve 17. A handwheel 7 is fixed on the side of the transmission rod 35 away from the sleeve 17, and the upper rack 32 and the lower rack 34 are staggered about the gear 36.

[0031] The moving component 4 is mounted on the base plate 1 and is used to drive the positioning rod 16 to move. The moving component 4 includes a fixed plate 41, a lead screw 42, a sliding block 43, a guide rod 44, and a drive motor 45. The fixed plate 41 is fixed to the top of the base plate 1, and the lead screw 42 is rotatably mounted between the fixed plate 41 and the U-shaped mounting bracket 11. The sliding block 43 is sleeved on the lead screw 42 and threadedly connected to the lead screw 42. The guide rod 44 is fixed between the fixed plate 41 and the U-shaped mounting bracket 11 and is parallel to the lead screw 42. The drive motor 45 is fixed to the side of the fixed plate 41 away from the U-shaped mounting bracket 11. In this embodiment, the guide rod 44 passes through the sliding block 43 and slides with the sliding block 43. The end of the lead screw 42 away from the U-shaped mounting bracket 11 passes through the fixed plate 41 and is fixed to the output end of the drive motor 45. The top of the sliding block 43 is connected to the bottom of the positioning rod 16. An opening 111 is provided on one side wall of the U-shaped mounting bracket 11 for the positioning rod 16 to pass through. In this embodiment, a bellows 81 sleeved on the outside of the lead screw 42 is fixed between the sliding block 43 and the fixed plate 41. The bellows 81 prevents debris from entering the thread gap of the lead screw 42.

[0032] When workers need to drill holes in roads with high soil moisture, they control the drive motor 45. The drive motor 45 starts and drives the lead screw 42 to rotate. Since the sliding block 43 is threadedly connected to the lead screw 42 and the guide rod 44 passes through the sliding block 43, the sliding block 43 moves along the axis of the lead screw 42. This causes the sliding block 43 to move the positioning rod 16, which in turn moves the upper clamping block 18 and the lower clamping block 19. The workers then turn the handwheel 7, which drives the transmission rod 35 and the gear 36 fixed to it to rotate. Since the upper rack 32 and the lower rack 34 are both meshed with the gear 36, and the upper rack 32 and the lower rack 34 are staggered about the gear 36, the gear 36 drives the upper rack 32 and the lower rack 34 to rotate. The upper rack 32 moves, driving the upper clamping block 18 to move, and the lower rack 34 moves the lower clamping block 19, thus bringing the upper clamping block 18 and the lower clamping block 19 closer together, thereby clamping the auger blade 14. At the same time, the operator controls the power motor 15 to start, which drives the auger blade 14 to rotate. The operator controls the upper electric push rod 23 to start, which drives the mounting plate 22 fixed to it, the connecting plate 21 fixed to the mounting plate 22, and the sliding plate 12 fixed to the connecting plate 21 to move, so that the sliding plate 12 drives the auger blade 14 to drill holes. At the same time, the mutual clamping of the upper clamping block 18 and the lower clamping block 19 cleans the sticky debris in the auger blade 14.

[0033] In this embodiment, an upper limit rod 5 is provided on the side wall of the upper rack 32 away from the lower rack 34. An upper sliding groove 171 is provided inside the sleeve 17 for the upper limit rod 5 to slide. A lower limit rod 6 is provided on the side wall of the lower rack 34 away from the upper rack 32, and a lower sliding groove 172 is provided inside the sleeve 17 for the lower limit rod 6 to slide. The upper limit rod 5 and the lower limit rod 6 are provided to prevent the upper rack 32 and the lower rack 34 from shifting during movement, thus ensuring the efficiency of transmission.

[0034] In this embodiment, a through hole 71 is provided through the handwheel 7, and an insertion rod 72 is provided inside the through hole 71. An insertion hole 173 is provided on the side of the sleeve 17 near the handwheel 7, for the insertion rod 72 to be inserted into. Multiple insertion holes 173 are provided and arranged in a circular array. When the upper clamping block 18 and the lower clamping block 19 clamp the auger blade 14, the operator passes the insertion rod 72 through the through hole 71 and then inserts the insertion rod 72 into the insertion hole 173. The limiting effect of the insertion rod 72 prevents the upper clamping block 18 and the lower clamping block 19 from loosening during the rotation of the auger blade 14.

[0035] In this embodiment, a mounting hole 161 is provided through the positioning rod 16, and a positioning hole 431 corresponding to the position of the mounting hole 161 is provided on the sliding block 43. A fixing hole 432 communicating with the positioning hole 431 is provided on the sliding block 43. A long rod 162 is provided in both the mounting hole 161 and the positioning hole 431, and a bolt 433 threadedly connected to the long rod 162 is provided in the fixing hole 432. When there are sticky debris in the upper clamping block 18 and the lower clamping block 19, the operator can loosen and remove the bolt 433 with a tool, and then remove the long rod 162. The positioning rod 16, the transmission assembly 3, the limiting plate 8, the upper clamping block 18 and the lower clamping block 19 can then be disassembled as a whole. After disassembly, the operator can clean the debris from the upper clamping block 18 and the lower clamping block 19, and then install the positioning rod 16, the transmission assembly 3 and the upper clamping block 18 and the lower clamping block 19 onto the sliding block 43 using the long rod 162 and the bolt 433.

[0036] In this embodiment, a limiting plate 8 is fixed on the positioning rod 16, and the limiting plate 8 abuts against the inner wall of the opening 111. The limiting plate 8 is provided to prevent the rotation of the auger blade 14 from damaging the threads of the lead screw 42 when the upper clamping block 18 and the lower clamping block 19 clamp the auger blade 14, thus ensuring the transmission accuracy and service life of the lead screw 42.

[0037] In this embodiment, an upper rubber pad 9 is fixed to the bottom of the upper clamping block 18, and a lower rubber pad 91 is fixed to the top of the lower clamping block 19. The upper rubber pad 9 and the lower rubber pad 91 are made of rubber and have a certain degree of flexibility and resilience. When the upper clamping block 18 and the lower clamping block 19 clamp the auger blade 14, the upper rubber pad 9 and the lower rubber pad 91 fit the auger blade 14 more closely, ensuring cleaning efficiency.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
