Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a grinding equipment for building construction processing. Background Technology

[0002] In building construction, steel structures are often used for the framework. During steel structure processing, burrs or uneven surfaces are unavoidable, and grinding is necessary to remove rust, stains, etc. Currently, steel grinding is often done manually with handheld grinders or using grinding devices.

[0003] In the existing technology, the grinding of metal frames is basically done manually using a handheld grinder, which has many drawbacks. On the one hand, the manual operation of the pneumatic grinder can easily lead to uneven grinding of the metal frame surface, which not only affects the grinding quality but also reduces the grinding speed. On the other hand, manual operation makes it difficult to achieve different grinding intensities, resulting in a limited grinding effect for metal frames with different degrees of burrs. In addition, some debris is generated during the grinding process, which poses a hazard to the environment and the health of the operators. Therefore, this application discloses a grinding equipment for building construction to meet the side grinding needs of metal frames. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a grinding equipment for building construction, which has advantages such as homogenized grinding of metal frames.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grinding device for building construction, comprising a mounting frame, an operating table fixedly mounted on the top of the mounting frame, a support platform fixedly mounted on the top center of the operating table, a metal frame body placed on the support platform, a grinding assembly for grinding the surface of the metal frame body on the operating table, the grinding assembly comprising multiple grinding wheels corresponding to the top side of the metal frame body, a guide assembly for moving the grinding wheels on the operating table, the position of the guide assembly being adapted to the top side of the metal frame body, the grinding assembly further comprising multiple sets of cylindrical grinding tools for grinding the sidewalls of the metal frame body, and an adjustment assembly for controlling the grinding intensity of the grinding wheels on the operating table.

[0006] Preferably, the guide assembly includes a guide frame corresponding to the position of the metal frame body. The guide frame includes an inner frame and an outer frame at the same height. The same guide slider is slidably fitted on the same side of the inner frame and the outer frame. A plurality of grinding wheels are respectively fitted in the corresponding guide sliders, and the two ends of the plurality of grinding wheels pass through the corresponding guide sliders and extend to the outer sides of the corresponding guide sliders.

[0007] Preferably, the bottom of the outer frame and the top of the inner frame are fixedly connected by a plurality of common arc-shaped fixing rods, and the plurality of arc-shaped fixing rods are respectively located on both sides of the guide frame. The mounting bracket is also fixedly installed with a plurality of electric telescopic rods corresponding to the four corners of the mounting frame. The telescopic ends of the plurality of electric telescopic rods all pass through the operating table and are fixedly connected to the four bottom corners of the outer frame. The minimum distance between two electric telescopic rods on the same side is greater than the maximum width of the metal frame body.

[0008] Preferably, a displacement assembly for moving multiple guide sliders is also fixedly installed on the outer frame. The displacement assembly includes multiple sets of compatible horizontal guide rails and electric sliders. The four horizontal guide rails are all fixedly installed on the top of the outer frame and are adapted to the position of the metal frame body. The multiple electric sliders are slidably sleeved on the corresponding horizontal guide rails. The top of the multiple electric sliders and the top of the corresponding guide slider are fixedly connected to the same arc-shaped connecting rod.

[0009] Preferably, each of the multiple guide sliders is equipped with a drive motor, the output end of the drive motor is fixedly connected to a drive gear via a coupling, and the top of each of the multiple grinding wheels is fixedly connected to a drive gear that meshes with the drive gear at the corresponding position.

[0010] Preferably, each of the multiple guide sliders is rotatably fitted with two corresponding driven shafts, the bottom of each of the multiple driven shafts is fixedly fitted with a cylindrical grinding tool that contacts the inner and outer walls of the metal frame body, and the top of each of the multiple grinding wheels is fixedly fitted with a wide-body gear, and the top of each of the multiple driven shafts is fixedly fitted with a driven gear that meshes with the corresponding wide-body gear, the thickness of the driven gear being less than the thickness of the wide-body gear.

[0011] Preferably, the adjustment assembly includes multiple lifting platforms that are rotatably mounted on the corresponding grinding wheels, multiple driving gears that are fixedly mounted on the corresponding lifting platforms, and multiple driven shafts that are slidably mounted in the corresponding lifting platforms.

[0012] Preferably, the bottom of each of the multiple lifting platforms is fixedly connected with multiple evenly distributed vertical guide rods, and the bottom ends of the multiple vertical guide rods pass through the corresponding guide sliders and extend to the bottom side of the corresponding guide sliders.

At the same time, when the grinding wheel rotates, it drives the wide-body gear to rotate synchronously, and the two driven gears meshing with the wide-body gear at the opposite position rotate synchronously, so that the driven shafts on both sides of the guide slider rotate synchronously, and drive the cylindrical grinding tools on both sides to rotate synchronously, so as to complete the synchronous grinding operation on both sides of the metal frame body, and thus realize the rapid grinding of the surface of the metal frame body. Compared with the manual grinding method in the prior art, the grinding efficiency is improved and the grinding effect is optimized.

[0017] (2) By adjusting the number of counterweights, since the maximum supporting force of the lifting spring on the lifting platform is constant, the change in the number of counterweights directly affects the total weight of the lifting platform, thereby compressing the lifting spring and indirectly changing the degree of pressure of the grinding wheel on the metal frame body, thereby changing the grinding intensity of the grinding wheel on the top of the metal frame body, thus adapting to the different deburring and grinding needs on different metal frame bodies, and further improving the practicality of the entire grinding device.

[0018] In summary, the present invention has advantages such as homogenized grinding of the metal frame. Attached Figure Description

[0035] Example 1

[0036] like Figure 1-7 As shown, a grinding device for building construction includes a mounting frame 1. An operating table 2 is fixedly mounted on the top of the mounting frame 1. A support platform is fixedly mounted at the center of the top side of the operating table 2. A metal frame body 5 is placed on the support platform. The operating table 2 is also equipped with a grinding assembly for grinding the surface of the metal frame body 5. The grinding assembly includes multiple grinding wheels 11 corresponding to the positions on the top side of the metal frame body 5. The operating table 2 is also equipped with a guide assembly for moving the grinding wheels 11. The position of the guide assembly is adapted to the top side of the metal frame body 5. The grinding assembly also includes multiple sets of cylindrical grinding tools 17 for grinding the sidewalls of the metal frame body 5. The operating table 2 is also equipped with an adjustment assembly for controlling the grinding intensity of the grinding wheels 11. When grinding the outer wall of the metal frame body 5, the metal frame body 5 is first placed on the support platform, and the guide assembly is controlled to move... The grinding mechanism moves the grinding components, which work together to quickly grind the top side of the metal frame body 5. Simultaneously, the grinding components also rotate the cylindrical grinding tools 17 on both sides, grinding the side walls of the metal frame body 5. This increases the grinding speed of the metal frame body 5 surface. Compared to existing technologies, this not only optimizes the grinding effect on the surface of the metal frame body 5 but also improves grinding efficiency. Furthermore, by setting an adjustment component, the grinding intensity can be adjusted according to the degree of burrs on the metal frame body 5, further improving the practicality of the entire grinding device. During grinding, the blocking effect of the grinding components and adjustment components effectively prevents debris from flying out of the grinding device and facilitates the subsequent collection of grinding debris remaining on the operating table 2, achieving a good dust prevention effect.

[0037] In a preferred embodiment of this invention, the guide assembly includes a guide frame corresponding to the position of the metal frame body 5. The guide frame includes an inner frame 3 and an outer frame 4 at the same height. A guide slider 6 is slidably mounted on the same side of both the inner frame 3 and the outer frame 4. Multiple grinding wheels 11 are respectively mounted within the corresponding guide slider 6, with both ends of the multiple grinding wheels 11 penetrating the corresponding guide slider 6 and extending to both sides of the corresponding guide slider 6. A displacement assembly for moving the multiple guide sliders 6 is also fixedly mounted on the outer frame 4. The displacement assembly includes multiple sets of compatible horizontal guide rails 7 and electric sliders 8. Four horizontal guide rails 7 are fixedly mounted on the top of the outer frame 4 and adapted to the position of the metal frame body 5. Multiple electric sliders 8 are slidably mounted on the corresponding horizontal guide rails 7. The top of block 8 is fixedly connected to the top of the corresponding side guide slider 6 with the same arc-shaped connecting rod 9. By setting a matching guide frame and guide slider 6, the displacement component can drive the guide slider 6 to move in a stable linear motion. The detailed process is as follows: After the metal frame body 5 is placed on the support platform on the operating table 2, the electric slider 8 on the corresponding side is controlled to run. Under the guidance of the corresponding horizontal guide rail 7, the electric slider 8 drives the guide slider 6 on the same side to move through the arc-shaped connecting rod 9, thereby making the grinding wheel 11 move in a straight line and complete the uniform grinding of the top of the metal frame body 5. Compared with the existing manual hand-held pneumatic grinding method, it can not only ensure the grinding effect on the top side of the metal frame body 5, but also improve the grinding efficiency of the top of the metal frame body 5, and improve the batch processing efficiency of the metal frame body 5.

[0038] In a preferred embodiment of this invention, the bottom of the outer frame 4 and the top of the inner frame 3 are fixedly connected to a plurality of common arc-shaped fixing rods 22, and the plurality of arc-shaped fixing rods 22 are respectively located on both sides of the guide frame. The mounting frame 1 is also fixedly installed with a plurality of electric telescopic rods 23 corresponding to the four corners of the mounting frame. The telescopic ends of the plurality of electric telescopic rods 23 all pass through the operating table 2 and are fixedly connected to the bottom four corners of the outer frame 4. The minimum distance between two electric telescopic rods 23 on the same side is greater than the maximum width of the metal frame body 5. By setting a plurality of arc-shaped fixing rods 22 on both sides of the guide frame, the plurality of electric telescopic rods 23 located at the four corners can run synchronously, and drive the outer frame 4 and the inner frame 3 to rise and fall synchronously through their telescopic ends, thereby facilitating the placement of the metal frame body 5 onto the support platform or the removal of the metal frame body 5 from the support platform after grinding.

[0039] In a preferred embodiment of this invention, each of the multiple guide sliders 6 is equipped with a drive motor 12. The output end of the drive motor 12 is fixedly connected to a drive gear 13 via a coupling. The top ends of multiple grinding wheels 11 are fixedly connected to drive gears 14 that mesh with the corresponding drive gears 13. Each of the multiple guide sliders 6 is rotatably fitted with two corresponding driven shafts 16. The bottom of each of the multiple driven shafts 16 is fixedly fitted with a cylindrical abrasive 17 that contacts the inner and outer walls of the metal frame body 5. The top ends of each of the multiple grinding wheels 11 are also fixedly fitted with wide-body gears 15. The top ends of each of the multiple driven shafts 16 are fixedly fitted with driven gears 18 that mesh with the corresponding wide-body gears 15. The thickness of the driven gears 18 is less than the thickness of the wide-body gears 15. The operation of the electric sliders 8 indirectly drives the guides. During the movement towards the slider 6, the synchronous control drive motor 12 operates, which in turn drives the drive gear 13 to rotate via the coupling, causing the drive gear 14 to rotate synchronously. This causes the grinding wheel 11 at the corresponding position to keep rotating, completing the grinding of the top side of the metal frame body 5 while moving. At the same time, the rotation of the grinding wheel 11 synchronously drives the wide-body gear 15 to rotate, causing the two driven gears 18 meshing with the wide-body gear 15 at the opposite position to rotate synchronously. This causes the driven shafts 16 on both sides of the guide slider 6 to rotate synchronously, driving the cylindrical grinding tools 17 on both sides to rotate synchronously, completing the synchronous grinding operation on both sides of the metal frame body 5. This achieves rapid grinding of the surface of the metal frame body 5, which improves grinding efficiency and optimizes grinding effect compared to the manual grinding method in the prior art.

[0040] In a preferred embodiment of this invention, the adjustment assembly includes multiple lifting platforms 10 rotatably mounted on corresponding grinding wheels 11, multiple driving gears 13 fixedly mounted on corresponding lifting platforms 10, and multiple driven shafts 16 slidably mounted within corresponding lifting platforms 10. The bottom of each lifting platform 10 is fixedly connected to multiple evenly distributed vertical guide rods 19. The bottom ends of the vertical guide rods 19 pass through corresponding guide sliders 6 and extend to the bottom side of the corresponding guide sliders 6. Each vertical guide rod 19 is also fitted with a lifting spring 20, the two ends of which abut against the corresponding guide sliders 6 and the lifting platform 10. The tops of the multiple lifting platforms 10 are... The device is equipped with counterweight slots, each containing a counterweight block 21. When surface polishing is required for metal frame bodies 5 with different degrees of burrs, the number of counterweight blocks 21 is adjusted according to the actual polishing intensity requirements of the metal frame bodies 5. Since the maximum supporting force of the lifting spring 20 on the lifting platform 10 is constant, the change in the number of counterweight blocks 21 directly affects the total weight of the lifting platform 10, thereby compressing the lifting spring 20 and indirectly changing the pressure of the grinding wheel 11 on the metal frame body 5. This changes the polishing intensity of the grinding wheel 11 on the top of the metal frame body 5, thus adapting to different deburring and polishing requirements on different metal frame bodies 5, further improving the practicality of the entire polishing device.

[0041] Work steps

[0042] After the metal frame body 5 is placed on the support platform, the electric slider 8 is controlled to move the guide slider 6 in a way that indirectly drives the guide slider 6. At the same time, the drive motor 12 is controlled to run, which in turn drives the drive gear 13 to rotate through the coupling. This causes the drive gear 14 to rotate synchronously, which in turn causes the grinding wheel 11 at the corresponding position to keep rotating. This completes the grinding of the top side of the metal frame body 5 while moving. At the same time, the rotation of the grinding wheel 11 drives the wide-body gear 15 to rotate synchronously, and causes the two driven gears 18 meshing with the wide-body gear 15 at the opposite position to rotate synchronously. This causes the driven shafts 16 on both sides of the guide slider 6 to rotate synchronously, and drives the cylindrical grinding tools 17 on both sides to rotate synchronously. This completes the synchronous grinding operation on both sides of the metal frame body 5, thereby achieving rapid grinding of the surface of the metal frame body 5. Compared with the manual grinding method in the prior art, this improves the grinding efficiency and optimizes the grinding effect.

[0043] When surface polishing is required for metal frame bodies 5 with different degrees of burrs, the number of counterweights 21 is adjusted according to the actual polishing intensity requirements of the metal frame body 5. Since the maximum supporting force of the lifting spring 20 on the lifting platform 10 is constant, the change in the number of counterweights 21 directly affects the total weight of the lifting platform 10, thereby compressing the lifting spring 20 and indirectly changing the pressure of the grinding wheel 11 on the metal frame body 5, thereby changing the polishing intensity of the grinding wheel 11 on the top of the metal frame body 5, thus adapting to different deburring and polishing requirements on different metal frame bodies 5, and further improving the application range of the entire polishing device.

[0044] Example 2

[0045] like Figure 5 and Figure 8-14 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0046] Furthermore, such as Figure 8-14 As shown, it also includes a positioning component 24 disposed on the support platform for limiting the metal frame body 5, a grinding component 25 disposed on the support platform for grinding the four corners of the metal frame body 5, and a dust removal component 26 disposed on the guide slider 6.

[0047] The positioning component 24 includes several sets of positioning blocks 241 that pass through and are raised and lowered on the support platform and are used to limit the inner and outer walls of the metal frame body 5, two sets of inclined surfaces symmetrically arranged on the upper end of the positioning blocks 241, a connecting plate 242 arranged on the lower end of the two opposing positioning blocks 241, a supporting elastic member 243 arranged between the connecting plate 242 and the bottom of the support platform, and a horizontal pressure plate 245 arranged on the guide slider 6 through an L-shaped hanger 244 and used to drive the positioning blocks 241 to descend.

[0048] It should be noted that the width of the positioning block 241 is greater than the diameter of the cylindrical mold 17 and the dust removal roller 261, so that the cylindrical mold 17 and the dust removal roller 261 can work normally after the horizontal pressure plate 245 drives the positioning block 241 to descend.

[0049] In this embodiment, the positioning component 24 and the guide slider 6 work together to limit the metal frame body 5 on the support platform, preventing the metal frame body 5 from shifting during the grinding process, thus improving the flatness of the grinding surface of the metal frame body 5 and increasing the grinding effect of the metal frame body 5. On the other hand, it can avoid the path of the cylindrical grinding tool 17, which ensures the limiting effect of the positioning component 24 on the metal frame body 5 without affecting the grinding work of the cylindrical grinding tool 17 on the side wall of the metal frame body 5.

[0050] In detail, after the metal frame body 5 is placed flat between the corresponding positioning blocks 241 on the support platform, the guide slider 6 moves the cylindrical grinding tool 17 to grind the metal frame body 5. The guide slider 6 drives the horizontal pressure plate 245 to contact the inclined surface of the positioning block 241 through the L-shaped hanger 244. The horizontal pressure plate 245 drives the positioning block 241 to descend through the inclined surface, so that the upper end of the positioning block 241 is flush with the upper surface of the support platform, thereby enabling the cylindrical grinding tool 17 to grind the side wall of the metal frame body 5. After the horizontal pressure plate 245 is separated from the positioning block 241, the positioning block 241 is lifted and reset by the elastic force of the supporting elastic element 243, and the metal frame body 5 is repositioned.

[0051] Furthermore, such as Figure 8-14 As shown, the grinding assembly 25 includes four grinding frames 251 that pass through and are raised and lowered on the support platform for grinding the four corner sidewalls of the metal frame body 5; a vertical shaft 252 that passes through and is rotatably mounted on the grinding frames 251; a grinding disc 253 mounted on the vertical shaft 252 for grinding the top of the four corners of the metal frame body 5; a support disc 254 mounted at the lower end of the vertical shaft 252; an arc-shaped strip 255 with a slope mounted at the bottom of the support disc 254; an L-shaped support plate 256 mounted at the bottom of the support platform; a protrusion 257 mounted on the L-shaped support plate 256 for driving the arc-shaped strip 255 to rise with the support disc 254; a toothed column 258 mounted at the upper end of the vertical shaft 252; and a rack 259 mounted on the guide slider 6 via a connecting rod for driving the toothed column 258 to rotate with the grinding disc 253.

[0052] It should be noted that the toothed column 258 has a ratchet structure, which means that the rack 259 can only drive the toothed column 258 to rotate in one direction. That is, when the arc-shaped strip 255 at the bottom of the support plate 254 passes the position of the protrusion 257, it can only move from the low slope to the high slope of the arc-shaped strip 255, which ensures that the arc-shaped strip 255 can drive the grinding frame 251 to rise, so as to achieve the effect of grinding the four corners of the metal frame body 5.

[0053] In this embodiment, the grinding component 25 and the guide slider 6 work together to automatically grind the four corners of the metal frame body 5, thereby improving the grinding effect of the metal frame body 5.

[0054] In detail, during the process of the guide slider 6 moving with the cylindrical abrasive 17 to grind the metal frame body 5, the rack 259 drives the toothed column 258 to rotate. The toothed column 258 drives the grinding disc 253 to rotate via the vertical shaft 252, so that the grinding disc 253 grinds the top of the four corners of the metal frame body 5. At the same time, the toothed column 258 drives the support plate 254 to rotate synchronously via the vertical shaft 252. When the arc-shaped strip 255 at the bottom of the support plate 254 rotates along the protrusion 257 on the L-shaped support plate 256, it causes the support plate to rotate. The support plate 254 lifts the grinding frame 251 via the vertical shaft 252, causing the grinding frame 251 to grind the side walls of the four corners of the metal frame body 5. When the arc-shaped strip 255 detaches from the protrusion 257 on the L-shaped support plate 256, the grinding frame 251 and the grinding plate 253 descend as a whole due to gravity, causing the grinding frame 251 to grind the top of the four corners of the metal frame body 5 again. This cycle repeats, allowing the grinding frame 251 and the grinding plate 253 to alternately grind the side walls and top of the four corners of the metal frame body 5.

[0055] Furthermore, such as Figure 8-14 As shown, the dust removal assembly 26 includes two sets of dust removal rollers 261 rotatably disposed at the bottom of the guide slider 6 and respectively located at the front and rear positions of the cylindrical mold 17, a hydraulic component 262 disposed on the guide slider 6 for driving the dust removal rollers 261 to rise and fall, several sets of cleaning boxes 263 disposed at the bottom of the support platform, and a cleaning hole 264 disposed on the support platform for the dust removal rollers 261 to pass through and descend to the cleaning box 263.

[0056] In this embodiment, the dust removal component 26 and the guide slider 6 work together to clean the side wall grinding surface of the metal frame body 5, thereby achieving a dust removal effect and improving the hygiene environment of the workshop.

[0057] In detail, during the process of the guide slider 6 carrying the cylindrical abrasive 17 forward to grind the metal frame body 5, the cleaning roller 261 in front of the cylindrical abrasive 17 can first clean the foreign objects on the side wall of the metal frame body 5, and the cleaning roller 261 behind can adhere to and clean the waste chips on the side wall of the metal frame body 5. When the guide slider 6 moves to the corner of the metal frame body 5, it stops, and the hydraulic component 262 drives the cleaning roller 261 to descend, so that the cleaning roller 261 enters the cleaning box 263 through the cleaning hole 264 for rinsing, so that the cleaning roller 261 can be reused.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
