Description

Technical Field

[0001] This utility model belongs to the technical field of wall grooving equipment, and in particular relates to a wall grooving auxiliary device with dustproof positioning. Background Technology

[0002] Cable trenching is a fundamental technique in building plumbing and electrical construction, referring to the process of creating grooves in walls or floors using specialized tools such as cutting machines. The trench depth must be determined based on the pipe specifications to meet the requirements for concealed installation of electrical conduits, water pipes, and other similar works. During construction, it is emphasized that the cable trenches must maintain a horizontal and vertical alignment, and diagonal trenches are strictly prohibited to ensure compliance with engineering standards. Concealed wiring systems require the use of 12.7mm 4-point PVC conduits for pipe protection, forming a complete concealed works system. Before construction, a laser level must be used for double-line positioning, and the trench width must be determined based on the pipe diameter (standard electrical conduit trench width is 20-25mm). After the cutting machine cuts the trench longitudinally along the marked lines, a hammer drill is used to remove any residue, ultimately creating a standard cable trench with a depth of 30-40mm. In special areas (such as shear walls), the trench depth must be controlled to not exceed the protective layer thickness.

[0003] The technical specifications for grooving operations are as follows:

[0004] 1. Positioning Accuracy: Laying out lines must strictly follow the conduit routing on the electrical construction drawings, with an allowable deviation of no more than ±5mm. 2. Groove Depth: The groove depth in concrete walls should not be less than 1.5 times the conduit diameter. In brick walls, the groove depth must ensure a 15mm protective layer remains after the conduit is embedded. 3. Process Standards: A dedicated grooving machine should be used. Direct chiseling with an electric hammer is prohibited. Corners should be beveled at a 45° angle.

[0005] In existing wall grooving operations, wall grooving (concrete walls, brick walls) mostly relies on handheld cutting machines (without positioning, groove depth deviation ±5mm, groove width deviation ±3mm), which has many shortcomings in project construction. On the one hand, the grooving process generates a large amount of dust, which not only seriously pollutes the construction environment and affects the health of construction workers, but may also drift into the surrounding area, adversely affecting other environments and personnel. Furthermore, manual control of straightness is poor (deviation >10mm within 3m), resulting in unsatisfactory grooving results and the need for secondary repairs.

[0006] Some wall grooving machines have been disclosed in the prior art. According to the search, a wall grooving machine with the publication number CN214293805U includes a housing, a mounting base and two or more saw blades. The diameter of the saw blades is of at least two specifications. The saw blades are connected to the mounting base, and the mounting base is disposed on the housing.

[0007] Although the device can groove walls, it requires manual operation and movement, making it inconvenient to control the straightness and requiring subsequent repairs. Therefore, a wall grooving auxiliary device with dustproof positioning that can effectively prevent dust and control the straightness was designed. Utility Model Content

[0042] See Figure 1 and Figure 2 A wall grooving auxiliary device with dustproof positioning

[0043] Example 1, the content disclosed in this example is as follows:

[0044] A wall grooving auxiliary device with dustproof positioning includes a support block 7, the support block 7 is connected to a linear moving component 1, the movable end of the linear moving component 1 can drive the grooving component 5 to move and adjust the lateral position of the grooving component 5.

[0045] The grooving assembly 5 includes a grooving saw 502 and a drive motor. The central shaft of the grooving saw 502 is rotatably connected to a connecting rod 6. The lower end of the central shaft of the grooving saw 502 is fixedly connected to the output shaft of the drive motor. The drive motor is fixed inside a motor cover 501. The motor cover 501 is fixedly connected to another connecting rod 6. The two connecting rods 6 are respectively fixedly connected to the upper and lower sides of the support block 7.

[0046] In this embodiment, the grooving component 5 is flexibly adjusted in lateral position by the linear movement component 1, which can accurately control the lateral position of the grooving to meet the wall grooving operations of different sizes and requirements. The drive motor can drive the grooving saw 502 to work and perform grooving operations.

[0047] It also includes a protective component 3, which includes a protective cover 301. The protective cover 301 is a cover with an opening on one side. The grooving saw 502 and the motor cover 501 are installed inside the protective cover. The upper end of the other side of the protective cover is fixedly connected to the end of the telescopic rod of the gas spring 304. The outer shell of the gas spring 304 is fixed to the corresponding connecting rod 6. The other side of the protective cover is provided with a through hole 305 for the connecting rod 6 to pass through. The upper end of the protective cover 301 is provided with a dust suction port 302. The dust suction port 302 is matched with an end cap 303. The dust suction port 302 can be connected to the suction pipe of the vacuum cleaner.

[0048] Example 2: Based on the above examples, this example further discloses the following:

[0049] Since dust and debris are generated during the grooving process, a protective component 3 is designed. The protective cover 301 abuts against the wall during the grooving process. Under the action of the gas spring 304, the protective cover 301 can stably abut against the wall. The end cap 303 of the dust suction port 302 can be removed to facilitate connection with the suction pipe of the vacuum cleaner. The dust and debris can be sucked away by the vacuum cleaner in time to avoid accumulation inside the protective cover 301.

[0050] The supporting block 7 is connected to the movable end of the linear movement component 1 through the grooving saw position adjustment component 4. The grooving saw position adjustment component 4 can adjust the distance between the grooving saw 502 and the wall.

[0051] The grooving saw position adjustment assembly 4 includes a sliding groove 402, a linear guide rail 403, an electric push rod 404, a bracket 405, and a limiting ring 406. One end of the linear guide rail 403 is fixedly connected to the bracket 405, and the bracket 405 is fixedly connected to the movable end of the linear movement assembly 1. The linear guide rail 403 is slidably connected to the sliding groove 402, and the sliding groove 402 is fixedly connected to the support block 7. The lower side of the sliding groove 402 is rotatably connected to the end of the outer shell of the electric push rod 404. The telescopic rod end of the electric push rod 404 is fixedly connected to the limiting ring 406, and the limiting ring 406 is rotatably connected to the lower side of one end of the linear guide rail 403.

[0052] Example 3: Based on the above examples, this example further discloses the following:

[0053] By setting the grooving saw position adjustment component 4, the grooving depth can be adjusted. In specific operation, the electric push rod 404 extends and retracts, driving the limit ring 406 to move. Since the limit ring 406 is rotatably connected to the lower side of one end of the linear guide rail 403, and the linear guide rail 403 is slidably engaged with the sliding slot 402, and the sliding slot 402 is fixedly connected to the support block 7, the support block 7 and the grooving saw 502 are driven to move, thereby realizing the adjustment of the distance between the grooving saw 502 and the wall, thus achieving the purpose of adjusting the grooving depth.

[0054] The linear motion assembly 1 includes a moving block 101, a screw 102, a linear track 103, and a first motor 104. The linear track 103 is fixedly connected to the first motor 104. The moving block 101 is slidably disposed in the groove of the linear track 103. The moving block 101 is screwed to the screw 102. The two ends of the screw 102 are respectively rotatably connected to the two ends of the linear track 103. The output shaft of the first motor 104 is fixedly connected to one end of the screw 102.

[0055] In this embodiment, the first motor 104 starts and drives the screw 102 to rotate. Since the moving block 101 is screwed onto the screw 102 and the moving block 101 is slidably disposed in the groove of the linear track 103, the moving block 101 will move linearly along the linear track 103 under the drive of the rotation of the screw 102. The movable end of the linear moving component 1 is fixedly connected to the bracket 405 in the grooving saw position adjustment component 4, thereby driving the grooving saw position adjustment component 4 and the grooving saw 502 to move linearly as a whole to adapt to the grooving requirements of different positions.

[0056] The linear track 103 is connected to the auxiliary positioning component 2 for positioning the linear track 103.

[0057] The auxiliary positioning component 2 includes support rods 202, which are fixed at the four corners of the linear track 103 and are respectively fixedly connected to positioning components 201.

[0058] In order to fix the position of the linear track 103, a positioning component 201 is provided, which can position the linear track 103.

[0059] The positioning element 201 is an electromagnet, electrically connected to the controller, which facilitates positioning when the wall is a steel structure. When energized, the positioning element 201 can be attracted to the wall surface, and when de-energized, the positioning element 201 detaches from the wall surface.

[0060] The positioning component 201 is a suction cup. The suction cup can adhere to the wall. The suction cup can be a pneumatic suction cup connected to an air pump. When the air pump is working, the suction cup adheres to / detaches from the wall. The principle is that the pneumatic suction cup generates suction force through changes in internal air pressure. When the air pump is started, a negative pressure environment is formed inside the suction cup, making it tightly adhere to the wall. When the air pump stops supplying air, the internal air pressure of the suction cup returns to normal, and it can easily detach from the wall. It is suitable for positioning operations on smooth walls and can effectively fix the position of the linear track 103.

[0061] Electromagnets are suitable for metal walls, while suction cups are suitable for non-metallic walls, effectively expanding the applicability of the device. Both electromagnets and pneumatic suction cups are existing technologies and will not be elaborated further, nor are they shown in the diagram. The protective cover is a transparent acrylic cover.

[0062] Example 4: Based on the above examples, this example further discloses the following:

[0063] This embodiment is a further elaboration based on Embodiment 1. Compared with Embodiment 1, this embodiment also has the following technical features:

[0064] A scraper 3011 is fixedly installed on one edge of the opening of the protective cover 301. The scraper 3011 is U-shaped, and its outer end is acute-angled. The scraper 3011 is designed to fit closely to the wall during the movement of the protective cover 301 and effectively scrape away debris and dust on the contact surface, preventing external debris from entering the interior of the protective cover 301. The acute-angled outer end design enhances the scraping effect of the scraper 3011, enabling it to clean the contact surface more efficiently. Furthermore, the scraper 3011 can better contact the wall surface, preventing dust generated during operation from overflowing.

[0065] Example 5: Based on the above examples, this example further discloses the following:

[0066] The method of using this utility model is as follows:

[0067] First, move the device to the location where wall grooving work needs to be carried out, and select the appropriate positioning part 201 for positioning according to the material of the wall;

[0068] If the wall is a steel structure, an electromagnet is selected as the positioning component 201. The electromagnet is energized by the controller so that it is attracted to the wall and the position of the linear track 103 is fixed.

[0069] If the wall surface is a smooth, non-metallic material, a suction cup is selected as the positioning component 201. The air pump is started to create a negative pressure environment inside the pneumatic suction cup, which then adheres tightly to the wall surface to complete the positioning of the linear track 103.

[0070] The first motor 104 is started, which drives the screw 102 to rotate. Since the moving block 101 is screwed onto the screw 102 and is slidably set in the groove of the linear track 103, the moving block 101 will move linearly along the linear track 103 under the drive of the rotation of the screw 102. The movable end of the linear moving component 1 is fixedly connected to the bracket 405 in the grooving saw position adjustment component 4, thereby driving the grooving saw position adjustment component 4 and the grooving saw 502 to move linearly as a whole, moving the grooving saw 502 to a suitable lateral position.

[0071] Remove the end cap 303 of the upper dust suction port 302 of the protective cover 301, connect the vacuum cleaner's suction pipe to the dust suction port 302, start the drive motor, and the drive motor drives the grooving saw 502 to work. According to the required grooving depth, start the electric push rod 404. The electric push rod 404 extends and retracts, causing the limiting ring 406 to move. Since the limiting ring 406 is rotatably connected to the lower side of one end of the linear guide rail 403, and the linear guide rail 403 is slidably engaged with the sliding groove 402, the sliding groove 402 also... The fixed connection support block 7 is used to move the support block 7 and the grooving saw 502. The distance between the grooving saw 502 and the wall is adjusted to achieve the required grooving depth. Then, the electric push rod 404 is controlled to stop working. At this time, the protective cover 301 abuts against the wall. Under the action of the gas spring 304, the protective cover 301 can stably abut against the wall. The scraper 3011 is in close contact with the wall to effectively scrape away debris, dust and other debris on the contact surface and prevent external debris from entering the interior of the protective cover 301.

[0072] Start the first motor 104 and the drive motor. The first motor 104 drives the screw 102 to rotate. Since the moving block 101 is screwed onto the screw 102 and is slidably set in the groove of the linear track 103, the moving block 101 will move linearly along the linear track 103 under the drive of the rotation of the screw 102. The movable end of the linear moving component 1 is fixedly connected to the bracket 405 in the grooving saw position adjustment component 4, thereby driving the grooving saw position adjustment component 4 and the grooving saw 502 to move linearly as a whole. During this process, the drive motor works, driving the grooving saw 502 to perform grooving operations during the movement. The dust and debris generated during the grooving process are promptly sucked away by the vacuum cleaner to prevent them from accumulating in the protective cover 301. After the grooving is completed, turn off all motors, control the grooving saw 502 to move backward away from the grooving hole, release the positioning component 201, and remove the device.

[0073] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
