Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, specifically to a drilling device and method for drilling holes in the walls of construction sites. Background Technology

[0002] In the electrical installation process on construction sites, cable securing is a crucial step in ensuring safe and stable power transmission. To firmly fix cables to the wall, pre-drilling holes is an essential preliminary step, requiring specialized pre-drilling equipment.

[0003] Most traditional drilling devices lack flexible height adjustment capabilities. When using them, workers find it difficult to accurately adjust the drilling position according to different locations and heights on the wall. They often need to repeatedly move the device or use auxiliary tools such as ladders, making the operation cumbersome and inefficient, which affects the subsequent cable fixing effect. On the other hand, there is a lack of effective means to collect and treat the large amount of dust and debris generated during the drilling process. This dust not only pollutes the construction site environment and increases the difficulty of cleaning, but also causes serious harm to the respiratory system of construction workers. Long-term exposure to such an environment can easily lead to occupational diseases such as pneumoconiosis. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a drilling device and method for drilling walls on construction sites. By combining a lifting drilling component and a collection component, it solves the problems of existing drilling devices lacking flexible height adjustment functions and the lack of effective collection and treatment methods for the large amount of dust and debris generated during the drilling process.

[0005] According to one embodiment of the present invention, a wall drilling device for construction sites is provided, comprising a movable frame and a lifting drilling assembly and a collecting assembly thereon; the lifting drilling assembly comprises: a mounting frame fixed on the movable frame; a motor disposed in the mounting frame, with a lead screw at its output end, the lead screw being rotatably connected to the mounting frame; a threaded sleeve threadedly connected to the lead screw; a lifting plate slidably disposed on the mounting frame and fixedly connected to the threaded sleeve; a drilling machine fixed on the lifting plate; and the collecting assembly fixed on the lifting plate and located below the drilling machine.

[0006] In one embodiment, the collection assembly includes: a positioning frame fixed to the lifting plate; two or more sleeves fixed to the positioning frame and the lifting plate, each having an inner limiting ring at one end; an extension rod passing through the sleeves, each having an outer limiting ring at one end opposite to the inner limiting ring; a spring disposed within the sleeves, applying an outward force to the extension rod; and a collection cover fixed to the extension rod, with its opening facing the drilling machine.

[0007] As one embodiment, the collection assembly further includes a collection chamber mechanism, which includes: a collection box fixed on the movable frame and connected to the collection hood by a collection hose; and a negative pressure fan disposed on the collection box.

[0008] In one embodiment, the top of the collection box is provided with a cover plate, and a handle is fixedly connected to the top of the cover plate.

[0009] In one embodiment, a base plate is fixedly connected to the bottom of the negative pressure fan, and one side of the base plate is fixedly connected to the movable frame.

[0010] In one embodiment, a mounting plate is fixedly connected to one side of the lifting plate, and the drilling machine is fixedly connected to the surface of the mounting plate.

[0011] In one embodiment, the four corners of the bottom of the mobile frame are connected to rollers via pivots, and a push rod is fixedly connected to one side of the top of the mobile frame.

[0012] In one embodiment, the mounting bracket has sliding grooves on both sides, and the lifting plate has a slider that cooperates with the sliding grooves fixedly connected to its side.

[0013] According to one embodiment of the present invention, a method for drilling holes in a construction site wall is provided, which uses the construction site wall drilling device as described above, and includes the following steps: S1, moving the drilling device to the position to be drilled; S2, starting the motor and moving the drilling machine to the drilling height; S3, adjusting the collecting component so that the collecting cover is against the wall surface; S4, starting the drilling machine and the collecting component; S5, turning off the drilling machine and the collecting component, and moving the drilling machine to the initial position.

[0014] As one implementation, after moving the drilling machine to its initial position, the dust and debris inside the collection box are also cleaned.

[0015] As described above and through practical experience, the construction site wall drilling device of the present invention uses a motor to drive a lead screw to rotate. The screw thread moves up and down, causing the lifting plate and the drilling machine to rise and fall synchronously. This structural design allows the drilling machine to be precisely adjusted according to different wall heights without the need for additional auxiliary tools, thus improving drilling efficiency and positioning accuracy. At the same time, the lead screw drive has the characteristics of high stability and high transmission precision, ensuring the stability of the drilling machine during the lifting process, ensuring the verticality and accuracy of the drilling, and providing a reliable guarantee for subsequent cable fixing.

[0016] In addition, the present invention utilizes the elasticity of the spring to ensure that the collection hood fits tightly against the wall. During the drilling process, the collection hood effectively gathers the dust and debris generated. The collection hose introduces the dust into the collection box. When the negative pressure fan is working, it creates negative pressure in the collection box, accelerating the intake of dust and achieving efficient collection of dust and debris generated during drilling. This reduces dust pollution at the construction site, protects the health of construction workers, and creates a clean construction environment. Attached Figure Description

[0025] like Figures 1 to 5 As shown, in this embodiment, a wall drilling device for construction sites is disclosed, including a mobile frame 1 and a lifting drilling assembly 2 and a collecting assembly 3 mounted thereon. The lifting drilling assembly 2 is fixedly connected to one side of the top of the mobile frame 1, and the collecting assembly 3 is fixedly connected to one side of the lifting drilling assembly 2.

[0026] The lifting drilling assembly 2 includes a mounting frame 21, a motor 22, a threaded sleeve 24, a lifting plate 25, and a drilling machine 27. The bottom of the mounting frame 21 is fixedly connected to the movable frame 1. The motor 22 is fixedly connected to the bottom of the inner cavity of the mounting frame 21. A lead screw 23 is fixedly connected to the output end of the motor 22. A threaded sleeve 24 is threadedly connected to the surface of the lead screw 23. A lifting plate 25 is fixedly connected to one side of the threaded sleeve 24. The lifting plate 25 is slidably connected to the mounting frame 21. A mounting plate 26 is fixedly connected to one side of the lifting plate 25. The drilling machine 27 is fixedly connected to the surface of the mounting plate 26. The top of the lead screw 23 is movably connected to the mounting frame 21 through a bearing.

[0027] The output end of motor 22 is fixedly connected to lead screw 23 via a coupling. Lead screw 23 is vertically mounted in the inner cavity of mounting bracket 21. Threaded sleeve 24 is tightly threaded with lead screw 23, allowing it to move accurately up and down along the axis of lead screw 23 when the lead screw 23 rotates. Mounting plate 26 is used to mount drilling machine 27. Multiple mounting holes are provided on its surface, and drilling machine 27 is securely fixed to mounting plate 26 with bolts, ensuring that drilling machine 27 will not loosen during operation. The top of lead screw 23 is movably connected to mounting bracket 21 via a high-precision bearing, ensuring smooth and stable rotation of lead screw 23. The motor 22 provides stable power for the rotation of the lead screw 23. The threaded engagement between the lead screw 23 and the threaded sleeve 24 can accurately convert the rotational motion of the motor into the linear motion of the threaded sleeve 24, thereby driving the lifting plate 25, the mounting plate 26 and the drilling machine 27 to rise and fall smoothly. During the lifting process, the drilling machine 27 can accurately reach the predetermined position at different heights on the wall without the need for ladders or other auxiliary tools, which not only improves the efficiency of drilling operations but also ensures the accuracy of the drilling position.

[0028] In this embodiment, the collection assembly 3 includes a positioning frame 31, two or more sleeves 32, an extension rod 34, a spring 33, and a collection cover 35. One side of the positioning frame 31 is fixedly connected to the lifting plate 25. Sleeves 32 are fixedly connected to both sides of the inner cavity of the positioning frame 31. A spring 33 is fixedly connected to the inner cavity of each sleeve 32. An extension rod 34 is fixedly connected to the bottom of each spring 33, and the spring 33 applies an outward force to the extension rod 34. An inner limiting ring 39 is provided on the inner side of one end of each sleeve 32, and an outer limiting ring 38 is provided on the outer side of one end of each extension rod 34. These two rings match to prevent the extension rod 34 from popping out of the sleeve 32. A collection cover 35 is fixedly connected to one side of the extension rod 34. The opening of the collection cover 35 faces the drilling machine 27, allowing it to collect dust and debris generated during drilling.

[0029] Furthermore, in this embodiment, the bottom of the collection cover 35 is connected to a collection hose 36, and the top of the movable frame 1 is fixedly connected to a collection chamber mechanism 37. The collection chamber mechanism 37 includes a collection box 371, the bottom of which is fixedly connected to the movable frame 1, one side of which is connected to the collection hose 36, and one side of which is connected to a negative pressure fan 372. The top of the collection box 371 is provided with a cover plate 4, and a handle is fixedly connected to the top of the cover plate 4. Rollers 5 are movably connected to the four corners of the bottom of the movable frame 1 through a pivot. A push rod is fixedly connected to one side of the top of the movable frame 1. Slide grooves 6 are provided on both sides of the mounting frame 21. A slider 7 that cooperates with the slide groove 6 is fixedly connected to one side of the lifting plate 25. A base plate 8 is fixedly connected to the bottom of the negative pressure fan 372, and one side of the base plate 8 is fixedly connected to the movable frame 1.

[0030] The positioning frame 31 moves synchronously with the lifting plate 25, ensuring that the collecting component 3 always corresponds to the drilling position. The spring 33 inside the sleeve 32 provides the extension rod 34 with elastic extension and retraction capabilities, allowing the collecting cover 35 to fit tightly against the wall, effectively preventing dust spillage and efficiently collecting dust and debris generated during drilling. This dust and debris are then transported to the collecting chamber mechanism 37 via the collecting hose 36, ensuring timely collection of dust and debris generated during drilling, reducing dust pollution at the construction site, and creating a healthy working environment for construction workers. The collecting box 371 is fixed to the moving frame 1 and connects with the collecting hose 36 to form a dust conveying channel. When the negative pressure fan 372 is working, it creates negative pressure inside the collecting box 371, allowing dust to enter the collecting box 371 through the collecting hose 36. The cover plate 4 cooperates with the collecting box 371 to prevent dust from escaping during device movement or operation, further avoiding secondary pollution. It should be noted that the air inlet of the negative pressure fan 372 is equipped with a filter screen to prevent dust from clogging the negative pressure fan.

[0031] The handle on cover plate 4 allows construction workers to easily open and close cover plate 4. When the dust collection box 371 is full, construction workers can easily open cover plate 4 for cleaning. Rollers 5 can adapt to complex ground environments such as uneven surfaces and areas with a lot of sand and gravel on construction sites, ensuring stable movement of the device. The push rod surface is non-slip, allowing construction workers to easily push the device by gripping the push rod. The cooperation between the slide groove 6 and the slider 7 provides guidance and limiting functions for the movement of the lifting plate 25. When the lifting plate 25 moves up and down along the screw 23 with the threaded sleeve 24, the slider 7 slides into the slide groove 6, effectively preventing the lifting plate 25 from shaking and ensuring stable operation of the lifting plate 25. The base plate 8 securely mounts the negative pressure fan 372 on the mobile frame 1, ensuring that the negative pressure fan 372 will not shift or loosen due to vibration or other factors during operation.

[0032] The working principle of this invention is as follows: After the device moves to the designated position, the motor 22 is started. The motor 22 drives the lead screw 23 to rotate. The rotational motion of the lead screw 23 is converted into linear motion of the threaded sleeve 24 along the axis of the lead screw 23. The threaded sleeve 24 drives the lifting plate 25, which is fixedly connected to it, to move up and down. As the lifting plate 25 moves, the mounting plate 26 and the drilling machine 27 fixed on the mounting plate 26 also move up and down synchronously. Construction personnel can control the operation of the motor 22 to make the drilling machine 27 accurately reach the predetermined drilling position according to the height requirements of the wall cable fixing.

[0033] After the drilling machine 27 reaches the designated position, it is started to begin drilling into the wall. During the drilling process, the collecting component 3 works synchronously, and the positioning frame 31 moves with the lifting plate 25 to ensure that the collecting component 3 always corresponds to the drilling position. The spring 33 inside the sleeve 32 gives the extension rod 34 elastic extension and retraction capabilities. When the collecting cover 35 contacts the wall, the spring 33 is compressed, making the collecting cover 35 fit tightly against the wall, effectively preventing dust from overflowing. The collecting cover 35 efficiently gathers the dust and debris generated during drilling and transports them to the collecting chamber mechanism 37 at the top of the moving frame 1 through the collecting hose 36 connected to the bottom of the collecting cover 35. The negative pressure fan 372 is started, creating a negative pressure environment in the collecting box 371. The collecting box 371 is connected to the collecting cover 35 through the collecting hose 36. Under the action of negative pressure, the dust and debris quickly enter the collecting box 371 through the collecting hose 36.

[0034] The present invention also provides a method for drilling holes in a construction site wall, which uses the above-mentioned construction site wall drilling device and includes the following steps: S1. Move the drilling device to the position to be drilled.

[0035] Specifically, the construction worker holds the push rod at the top of the mobile frame 1 and pushes the device to the vicinity of the wall where drilling is required. Using the rollers 5 at the four corners of the bottom of the mobile frame 1, the device is moved smoothly on the uneven ground of the construction site. After adjusting the device to a suitable drilling position, the rollers 5 can be fixed as needed to prevent the device from shifting during the drilling process.

[0036] S2. Start motor 22 and move drilling machine 27 to drilling height.

[0037] Specifically, first check whether all components of the lifting drilling assembly 2 are securely connected, ensuring that the motor 22, lead screw 23, threaded sleeve 24, etc., are without abnormalities. Confirm that the sliding grooves 6 on both sides of the mounting bracket 21 and the sliders 7 on the lifting plate 25 are properly engaged, ensuring smooth lifting. Then start the motor 22, and the output end of the motor 22 drives the lead screw 23 to rotate. The rotational motion of the lead screw 23 is converted into linear motion of the threaded sleeve 24 along the axis of the lead screw 23 through the threaded engagement. The threaded sleeve 24 drives the lifting plate 25, the mounting plate 26, and the drilling machine 27 to rise and fall synchronously. According to the height requirements for fixing the wall cable, by controlling the forward and reverse rotation and the running time of the drive motor 22, the drilling machine 27 accurately reaches the predetermined drilling height position.

[0038] S3. Adjust the collection component 3 so that the collection cover 35 is pressed against the wall.

[0039] Specifically, observe whether the collection cover 35 of the collection component 3 corresponds to the position of the wall. If the wall is not flat, the extension rod 34 can be extended or retracted by the spring 33 in the sleeves 32 on both sides of the inner cavity of the positioning frame 31, so that the collection cover 35 fits tightly against the wall and ensures the dust collection effect.

[0040] S4. Start the drilling machine 27 and the collection assembly 3.

[0041] Specifically, after confirming that the drilling machine 27 is properly positioned and the collection cover 35 is in contact with the wall, start the drilling machine 27. The drilling machine 27 begins drilling into the wall. At this time, care must be taken to keep the device stable and avoid human shaking. While the drilling machine 27 is working, start the negative pressure fan 372 in the collection chamber mechanism 37. The negative pressure fan 372 creates negative pressure in the collection box 371. The dust and debris generated during drilling are gathered by the collection cover 35 and sucked into the collection box 371 through the collection hose 36, achieving efficient dust collection and reducing pollution at the construction site.

[0042] S5. Turn off the drilling machine 27 and the collection component 3, and move the drilling machine 27 to the initial position.

[0043] Specifically, after drilling is completed, first turn off the drilling machine 27 to stop drilling operations, then turn off the negative pressure fan 372 to stop dust collection.

[0044] Afterwards, if another hole needs to be drilled, repeat the above steps; if no longer needed, push the device to the designated storage location. When the dust collection box 371 is full, open the cover 4 using the handle on the cover 4 to clean the dust and debris inside the collection box 371. After cleaning, close the cover 4 for next use.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
