Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically a grinding device for building materials used in road and bridge engineering. Background Technology

[0002] Building materials used in road and bridge engineering, such as stone and concrete components, often require polishing during production and installation. For stone, polishing is an essential process to achieve the required flatness and smoothness, ensuring an aesthetically pleasing surface and meeting functional requirements such as slip resistance. For instance, uneven or rough surfaces on bridge decorative stone not only affect the overall aesthetics of the bridge but may also pose safety hazards.

[0003] In the past, the grinding of building materials in road and bridge engineering often relied on manual labor. Workers used handheld grinding tools, such as sandpaper and small grinders. This method was labor-intensive, inefficient, and it was difficult to ensure uniform grinding quality, easily resulting in over- or under-grinding. For example, in grinding large areas of bridge concrete, manual grinding rarely achieved the same effect across the entire bridge surface, affecting the smoothness and aesthetics of the bridge deck.

[0004] Later, some simple mechanical grinding equipment emerged, such as disc grinders. While these devices improved grinding efficiency to some extent, their functions were relatively limited and their flexibility was insufficient. For some complex-shaped building materials with special structures, such as stone components with curves or grooves, or irregularly shaped concrete components, simple mechanical grinding equipment is difficult to use effectively, often requiring secondary manual processing, which increases construction costs and time. Therefore, there is an urgent need to improve a grinding device for building materials used in road and bridge engineering to solve the above problems. Utility Model Content

[0024] Example 1:

[0025] Existing clamping devices struggle to effectively hold complex-shaped building materials with unique structures, such as curved or grooved stone components or irregularly shaped concrete members. Furthermore, they require significant time for disassembly and reinstallation when dealing with materials of different shapes. Therefore, this device incorporates a clamping mechanism that enables rapid clamping of materials of various shapes, offering greater versatility. Please refer to [link / reference].

[0026] The screw 204 is a bidirectional screw. Clamps 205 are movably installed on both sides of the screw 204 via threads. The clamps 205 are movably installed in the slide groove 203. An air chamber 207 is provided in the clamp 205. An air pump interface 206 is provided on the side of the clamp 205. The air pump interface 206 is connected to the air chamber 207.

[0027] The clamp 205 has multiple sets of limiting cavities 208 on its inner side. The limiting cavities 208 are connected to the air cavity 207. A push rod 209 is movably installed in the limiting cavity 208.

[0028] Place the material to be processed on the clamping table 201. First, start the motor 202 and drive the clamp 205 to approach the material through the action of the screw 204 to clamp it. When it is close to the material, inject air into the air pump interface 206 to push out the push rod 209 and quickly clamp the material according to its different shapes.

[0029] Example 2:

[0030] Building upon Example 1, this device also includes a grinding mechanism capable of autonomously adjusting its angle. However, existing grinding mechanisms are relatively limited in function and flexibility. For complex-shaped building materials with special structures, such as stone components with curves or grooves, or irregularly shaped concrete components, simple mechanical grinding equipment is insufficient for effective grinding, often requiring secondary manual processing, which increases construction costs and time. Figures 4-5 This utility model provides a technical solution: a grinding device for building materials used in road and bridge engineering. The grinding mechanism includes a protective cover 2. A fixing frame 301 is fixedly installed in the middle part of the protective cover 2. A slider 302 is movably installed on the top of the fixing frame 301. A cylinder 303 is fixedly installed below the slider 302. The output end of the cylinder 303 is fixedly installed on the motor base. A motor 304 is fixedly installed below the motor base.

[0031] The output shaft of motor 2 304 is fixedly mounted on drive shaft 305. A slide groove 2 307 is provided at the top center of the protective cover 2.

Slider 306 is movably mounted on guide rod 308. Slider 306 is movably mounted on screw 2 310 by thread. A fixed connecting rod 311 is fixedly mounted below slider 306. The end of fixed connecting rod 311 is fixedly mounted on mounting base 312. A bearing 313 is fixedly mounted in mounting base 312.

[0032] The drive shaft 305 passes through the slider 306. A universal joint coupling 317 is fixedly installed at the end of the drive shaft 305. A driven shaft 318 is fixedly installed at the other end of the universal joint coupling 317. A grinding head 314 is fixedly installed at the end of the driven shaft 318.

[0033] After the material is clamped, the motor 304 is started to drive the grinding head 314 to rotate and grind the material. When angle adjustment is required, the cylinder 303 is started to control the lifting and lowering of the drive shaft 305. Under the action of the universal joint coupling 317, the grinding head is deflected to achieve the function of multi-angle grinding.

[0034] Example 3:

[0035] In conjunction with Embodiments 1 and 2, a large amount of dust is generated during the grinding of these building materials. If this dust is not cleaned up, it will pollute the environment and even endanger human health. Therefore, this device is also equipped with a cleaning mechanism. Please refer to [link / reference needed]. Figure 6This utility model provides a technical solution: a grinding device for building materials used in road and bridge engineering. The cleaning mechanism includes a protective cover 2, on which a water pump 401 is fixedly installed. Water pipe 402 and water pipe 403 are fixedly installed on the water pump 401.

Water pipe 403 passes through the protective cover 2 and is fixedly installed on a mounting base 312. The water outlet is aligned with the nozzle position. A recovery air pump 406 is fixedly installed on the opposite side of the water pump 401. An air pipe 407 is fixedly installed at the air intake of the recovery air pump 406. The air pipe 407 passes through the protective cover 2 and is fixedly installed on a dust cover 408. The dust cover 408 is fixedly installed below the mounting base 312.

[0036] During the grinding process, water pump 401 and recovery air pump 406 are started. The dust generated during the grinding process is dissolved through water pipe 2 403. The water-soluble dust flows into the wastewater recovery device designed in the base 1 under the action of guide table 404. After removing impurities, it is transported back into the equipment through water pipe 1 402. At the same time, some water-soluble dust is recovered into the recovery air pump 406 under the action of dust cover 408 and air pipe 407.
