Description

Technical Field

[0001] This invention relates to the field of concrete grinding technology, and more specifically to a grinding device with automatic feeding capability. Background Technology

[0002] Concrete grinding equipment is a key piece of equipment used for surface treatment in construction engineering. When concrete is poured and solidified during the pouring of bridge piers or concrete columns, burrs of solidified concrete will appear on the outer side of the top of the concrete piers or columns, making it impossible for the concrete columns to be connected with the precast splicing modules. In order to ensure normal splicing with the precast splicing modules, it is necessary to grind and cut the top of the bridge piers or concrete columns.

[0003] The existing equipment has some shortcomings during use, as detailed below:

[0004] The current grinding work on bridge piers or concrete columns is carried out on top of the bridge piers or concrete columns, and the operator needs to be on top of the bridge piers or concrete columns to operate. Therefore, when grinding multiple bridge piers or concrete columns repeatedly, it is inconvenient for the user to move the equipment to the bridge piers or concrete columns, resulting in a low loading speed of the bridge piers or concrete columns relative to the equipment, thus resulting in low grinding efficiency.

[0005] Existing equipment can only grind the top of bridge piers or concrete columns. However, when splicing with precast modules, in order to ensure effective positioning at the splice point, a positioning notch needs to be made on the top to match the positioning groove on the precast module. Currently, the positioning groove on the top of bridge piers or concrete columns is made manually by workers, which makes it difficult to ensure that the positioning groove can match the precast module well, and therefore it is not convenient to use. Summary of the Invention

[0013] Furthermore, there is a clearance fit between the diameter of the first hydraulic telescopic rod and the span of the top opening of the annular positioning groove, a clearance fit between the diameter of the first limiting circular plate and the width of the inner side of the annular positioning groove, a clearance fit between the thickness of the first limiting circular plate and the height of the inner side of the annular positioning groove, a telescopic hole is provided on the outer side of the guide positioning ring, a clearance fit between the diameter of the telescopic hole of the guide positioning ring and the diameter of the inner opening of the telescopic positioning rod, and a clearance fit between the diameter of the telescopic guide rod and the diameter of the inner opening of the telescopic positioning rod.

[0015] Furthermore, the cross-sectional dimensions of the guide hole are the same as those of the positioning grinding block. The top of the rotating adjustment block is provided with a positioning threaded hole. The inner thread of the positioning threaded hole of the rotating adjustment block and the outer thread of the positioning bolt are mutually engaged. The diameter of the guide hole is clearance-fitted with the width of the arc-shaped pushing groove. The width of the guide groove is the same as the width of the arc-shaped pushing groove. The teeth on the outer side of the transmission gear ring and the teeth on the outer side of the transmission gear mesh with each other.

[0016] The technical effects and advantages of this invention are as follows:

[0017] In this invention, when grinding burrs formed by the solidification of concrete on the top of bridge piers or concrete columns, the moving wheel is moved by pushing the device, and the moving wheel is extended by the operation of the second hydraulic cylinder, raising the first fixed plate to its highest position. Then, the grinding assembly is roughly aligned with the top of the bridge pier or concrete column. Then, the rotating shaft is rotated by the operation of the first servo motor, which in turn rotates the guide plate. Under the connection between the positioning rod and the guide plate and the meshing positioning of the transmission gear and the transmission gear ring, the adjusting device rotates synchronously, which in turn drives the grinding assembly to rotate. Through the guide groove, guide rod, and arc-shaped push... The top of the first positioning rod causes the guide plate and adjusting device to rotate, which in turn drives the positioning groove grinding device to rotate. Through the connection between the second rotating positioning block and the telescopic guide rod, the positioning groove grinding device rotates while the adjusting and pushing device rotates. As the grinding assembly rotates, the second hydraulic cylinder works to drive the second hydraulic telescopic rod to gradually retract, causing the grinding assembly to slowly approach the top of the bridge pier or concrete column, thereby grinding the top of the bridge pier or concrete column. This effectively removes the hardened concrete burrs on the top of the bridge pier or concrete column, ensuring grinding efficiency.

[0018] When it is necessary to bevel the outer top of a bridge pier or concrete column, this invention uses a first hydraulic cylinder to extend a first hydraulic telescopic rod, which in turn lowers a first limiting circular plate. This pushes an adjusting device downwards, causing a rotating adjusting block to rotate relative to the first and second rotating positioning rods. During this rotation, the telescopic guide rod and the second limiting circular plate extend beyond the inner side of the telescopic positioning rod. The tilt angle of the rotating adjusting block is then adjusted according to the required bevel angle. A second servo motor drives a transmission gear to rotate, which in turn drives the adjusting device to rotate. This causes the arc-shaped pushing groove to rotate and push the first positioning rod to extend to the outermost side. The bottom of the grinding assembly is then adjusted, and the first servo motor drives the positioning groove grinding device to rotate, simultaneously moving the positioning groove grinding device inwards. This completes the bevel cutting of the bridge pier or concrete column, facilitating bevel cutting using the same equipment after burr grinding, making it convenient for users.

[0019] This invention involves creating positioning grooves on the top of bridge piers or concrete columns. A first hydraulic cylinder extends a first hydraulic telescopic rod, which in turn lowers an adjusting device. This causes a rotating adjusting block to be perpendicular to the bottom of the first rotating positioning block and the top of the second rotating positioning block. A second servo motor then pushes the positioning groove grinding device outwards to its maximum extent. The distance between the bottom of the grinding assembly and the top of the bridge pier or concrete column is adjusted. The first servo motor then rotates the positioning groove grinding device, while the second servo motor moves the device closer together, thus completing the creation of the positioning groove. This ensures that the center of the positioning groove overlaps with the center of the bridge pier or concrete column, guaranteeing a good fit between the positioning groove and the prefabricated module.

[0020] When the rotating adjustment block is not long enough when creating positioning slots or slopes, the positioning bolts can be removed, and then the adjusting grinding plate can be removed and installed at the second positioning notch to extend the guide hole. This facilitates the adjustment of the equipment according to actual needs, allowing the equipment to adapt to more construction situations. Furthermore, the equipment can be moved to another pier or concrete column by pushing, making it easy to replace the pier or concrete column, thereby ensuring the equipment's material feeding efficiency.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The automatic feeding grinding device involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Reference Figures 1 to 7 This invention provides an automatic feeding grinding device, including a moving positioning device 1, a transmission device 2 mounted on the top of the moving positioning device 1, an adjusting device 3 mounted on the bottom of the transmission device 2, a positioning groove grinding device 4 mounted on the bottom of the adjusting device 3, an adjusting pushing device 5 fixedly connected to the outer side of the positioning groove grinding device 4, and a grinding assembly 6 fixedly connected to the bottom of the adjusting device 3. The moving positioning device 1 includes a first fixing plate 101, a second fixing plate 102 fixedly connected to the front and back of the first fixing plate 101, and a second fixing plate 102 fixedly connected to the top sides of the first fixing plate 101 and the top of the second fixing plate 102. A hydraulic cylinder 103 is provided. A first hydraulic telescopic rod 104 is fixedly connected to the bottom of the first hydraulic telescopic rod 104. A first limiting circular plate 105 is fixedly connected to the bottom of the first fixed plate 101. Second hydraulic telescopic rods 106 are fixedly connected to both sides of the bottom of the first fixed plate 101. A second hydraulic cylinder 107 is fixedly connected to the bottom of the second hydraulic cylinder 106. Moving wheels 108 are fixedly connected to the four corners of the bottom of the second hydraulic cylinder 107. When grinding burrs formed by the solidification of concrete on the top of bridge piers or concrete columns, the moving wheels 108 are moved by pushing the equipment, and the second hydraulic cylinder 107 is used for further grinding. The moving wheel 108 extends, raising the first fixed plate 101 to its highest position. The grinding assembly 6 is then roughly aligned with the top of the bridge pier or concrete column. The first servo motor 201 drives the rotating shaft 202 to rotate, which in turn rotates the guide plate 203. The connection between the positioning rod 301 and the guide plate 203, along with the meshing of the transmission gear 208 and the transmission ring 305, causes the adjusting device 3 to rotate synchronously. This, in turn, drives the grinding assembly 6 to rotate. The guide groove 204, guide rod 205, and arc-shaped pushing groove 304 align the top of the first positioning rod 401, causing the guide plate 201 to rotate. While the adjusting device 3 rotates, it drives the positioning groove grinding device 4 to rotate. Through the connection between the second rotating positioning block 4014 and the telescopic guide rod 505, the positioning groove grinding device 4 rotates while driving the adjusting push device 5 to rotate. While the grinding assembly 6 rotates, the second hydraulic cylinder 107 works to drive the second hydraulic telescopic rod 106 to gradually retract, so that the grinding assembly 6 slowly approaches the top of the bridge pier or concrete column, thereby grinding the top of the bridge pier or concrete column. This effectively removes the concrete hardening burrs on the top of the bridge pier or concrete column, ensuring grinding efficiency.

[0031] In a preferred embodiment, the transmission device 2 includes a first servo motor 201, the output shaft of which is fixedly connected to a rotating shaft 202. A guide plate 203 is fixedly connected to the bottom of the rotating shaft 202. A guide groove 204 is formed at the top of the guide plate 203, and a guide rod 205 is formed on the inner side of the guide groove 204. A third fixing plate 206 is fixedly connected to the outer side of the guide plate 203, and a second servo motor 207 is fixedly connected to the top of the third fixing plate 206. A transmission gear 208 is fixedly connected to the output shaft of the second servo motor 207. When it is necessary to create a bevel angle on the outer side of the top of the bridge pier or concrete column, the first hydraulic cylinder 103 operates to extend the first hydraulic telescopic rod 104, which in turn causes the first limiting plate 105 to descend. This then pushes the adjusting device 5 downwards, causing the rotating adjusting block 409 to move downwards from the first rotating positioning rod 408 and the second rotating... The positioning rod 4013 rotates relative to the first rotating positioning block 405 and the second rotating positioning block 4014. During the rotation of the rotating adjustment block 409, the telescopic guide rod 505 and the second limiting circular plate 506 extend out of the inner side of the telescopic positioning rod 504. Then, the tilt angle of the rotating adjustment block 409 is adjusted according to the actual needs of the bevel angle. Then, the second servo motor 207 drives the transmission gear 208 to rotate, which in turn drives the adjustment device 3 to rotate, so that the arc-shaped pushing groove 304 rotates and pushes the first positioning rod 401 to spread out to the outermost side. Then, the bottom of the grinding assembly 6 is adjusted. Then, the first servo motor 201 drives the positioning groove grinding device 4 to rotate, and at the same time, it drives the positioning groove grinding device 4 to move inward. This completes the bevel angle opening work on the bridge pier or concrete column, which is convenient for bevel angle opening after the burr grinding is completed, making it convenient for users to use.

[0032] In a preferred embodiment, the adjusting device 3 includes a connecting positioning rod 301, a positioning bearing 302 is installed on the outer side of the connecting positioning rod 301, a pushing circular plate 303 is installed on the outer side of the positioning bearing 302, an arc-shaped pushing groove 304 is opened on the top of the pushing circular plate 303, and a transmission gear ring 305 is fixedly connected to the outer side of the pushing circular plate 303.

[0033] In a preferred embodiment, the positioning groove grinding device 4 includes a first positioning rod 401, a guide hole 402 on the outer side of the first positioning rod 401, a second positioning rod 403 fixedly connected to the bottom of the first positioning rod 401, a third positioning rod 404 fixedly connected to the other end of the second positioning rod 403, a first rotating positioning block 405 fixedly connected to the bottom of the third positioning rod 404, a rotating positioning groove 406 on the outer side of the first rotating positioning block 405, and a first rounded corner 407 on one side of the first rotating positioning block 405. A first rotating positioning rod 408 is installed on the inner side of the groove 406. A rotating adjusting block 409 is fixedly connected to the outer side of the first rotating positioning rod 408. A first positioning notch 4010 is provided on the front and back sides of the rotating adjusting block 409 near the first rotating positioning block 405. A second rounded corner 4011 is provided on the side of the rotating adjusting block 409 near the first rotating positioning block 405. A second positioning notch 4012 is provided on the top side of the rotating adjusting block 409 away from the first rotating positioning block 405. A second rotating positioning rod 4013 is fixedly connected to the front and back sides. A second rotating positioning block 4014 is installed on the outer side of the second rotating positioning rod 4013. A third rounded corner 4015 is provided on the side of the second rotating positioning block 4014 near the rotating adjusting block 409. A positioning groove is opened on the top of the pier or concrete column to be aligned. The first hydraulic cylinder 103 pushes the first hydraulic telescopic rod 104 to extend, which in turn drives the adjusting and pushing device 5 to descend, so that the rotating adjusting block 409 is perpendicular to the bottom of the first rotating positioning block 405 and perpendicular to the second rotating positioning block 409. At the top of block 4014, the second servo motor 207 drives the positioning groove grinding device 4 to spread outward to its maximum extent. Then, by adjusting the distance between the bottom of the grinding component 6 and the top of the pier or concrete column, the first servo motor 201 drives the positioning groove grinding device 4 to rotate. At the same time, the second servo motor 207 drives the positioning groove grinding device 4 to move closer, thus completing the opening of the positioning groove. This ensures that the center of the opening positioning groove overlaps with the center of the pier or concrete column, guaranteeing that the opening positioning groove can fit well with the prefabricated module.

[0034] In a preferred embodiment, the adjusting and pushing device 5 includes a guide positioning ring 501, a pushing and limiting ring 502 fixedly connected to the top of the guide positioning ring 501, an annular positioning groove 503 opened on the top of the pushing and limiting ring 502, a telescopic positioning rod 504 fixedly connected to the outer side of the first positioning rod 401, a second limiting circular plate 506 provided on the inner side of the telescopic positioning rod 504, and a telescopic guide rod 505 fixedly connected to the inner side of the second limiting circular plate 506. When the rotating adjusting block 409 is not long enough when opening the positioning groove or slope, the positioning bolt 604 can be removed, and then the adjusting grinding plate 603 can be removed and installed at the second positioning notch 4012 to complete the extension of the guide hole 402. This facilitates the adjustment of the equipment according to actual usage needs, allowing the equipment to adapt to more construction situations. Furthermore, the equipment can be moved to another pier or concrete column by pushing, making it easy to replace the pier or concrete column, thereby relatively ensuring the material feeding efficiency of the equipment.

[0035] In a preferred embodiment, the grinding assembly 6 includes a grinding disc 601, a positioning grinding block 602 is fixedly connected to the outer side of the grinding disc 601, an adjusting grinding plate 603 is sleeved on the outer side of the positioning grinding block 602, a bolt positioning hole 605 is provided on the top of the positioning grinding block 602, and a positioning bolt 604 is installed on the top of the adjusting grinding plate 603.

[0036] In a preferred embodiment, the diameter of the first hydraulic telescopic rod 104 and the span of the top opening of the annular positioning groove 503 are clearance-fitted; the diameter of the first limiting circular plate 105 and the width of the inner side of the annular positioning groove 503 are clearance-fitted; the thickness of the first limiting circular plate 105 and the height of the inner side of the annular positioning groove 503 are clearance-fitted; a telescopic hole is provided on the outer side of the guide positioning ring 501; the diameter of the telescopic hole of the guide positioning ring 501 and the diameter of the inner opening of the telescopic positioning rod 504 are clearance-fitted; and the diameter of the telescopic guide rod 505 and the diameter of the inner opening of the telescopic positioning rod 504 are clearance-fitted.

[0037] In a preferred embodiment, the first positioning rod 401 and the second positioning rod 403, and the second positioning rod 403 and the third positioning rod 404 are connected by a bent pipe. The diameter of the guide hole 402 is clearance-fitted with the diameter of the guide rod 205. The center of the second fillet 4011 overlaps with the center of the first rotary positioning rod 408. The center of the first fillet 407 overlaps with the center of the second fillet 4011. The center of the third fillet 4015 overlaps with the center of the second rotary positioning rod 4013. The rotary adjusting block 409 has a fillet on the side near the second rotary positioning block 4014. The center of the fillet on the side of the rotary adjusting block 409 near the second rotary positioning block 4014 overlaps with the center of the second rotary positioning rod 4013.

[0038] In a preferred embodiment, the cross-sectional dimensions of the guide hole 402 are the same as those of the positioning grinding block 602. The top of the rotating adjustment block 409 is provided with a positioning threaded hole. The inner thread of the positioning threaded hole of the rotating adjustment block 409 and the outer thread of the positioning bolt 604 are mutually engaged. The diameter of the guide hole 402 is clearance-fitted with the width of the arc-shaped push groove 304. The width of the guide groove 204 is the same as the width of the arc-shaped push groove 304. The outer teeth of the transmission gear ring 305 and the outer teeth of the transmission gear 208 mesh with each other.

[0039] The working principle of this invention is as follows: When grinding burrs formed by the solidification of concrete on the top of bridge piers or concrete columns, the moving wheel 108 is moved by pushing the device, and the moving wheel 108 is extended by the operation of the second hydraulic cylinder 107, so that the first fixed plate 101 is raised to its highest position. Then, the grinding assembly 6 is roughly aligned with the top of the bridge pier or concrete column. Then, the rotating shaft 202 is rotated by the operation of the first servo motor 201, which in turn drives the guide plate 203 to rotate. Under the connection between the connecting positioning rod 301 and the guide plate 203 and the meshing positioning of the transmission gear 208 and the transmission gear ring 305, the adjusting device 3 rotates synchronously, which then drives the grinding assembly 6 to rotate. Through the guide groove 204, the guide... The rod 205 and the arc-shaped pushing groove 304, when positioned on the top of the first positioning rod 401, cause the guide plate 203 and the adjusting device 3 to rotate, which in turn drives the positioning groove grinding device 4 to rotate. Through the connection between the second rotating positioning block 4014 and the telescopic guide rod 505, the positioning groove grinding device 4 rotates while the adjusting pushing device 5 rotates. As the grinding assembly 6 rotates, the second hydraulic cylinder 107 works to drive the second hydraulic telescopic rod 106 to gradually retract, causing the grinding assembly 6 to slowly approach the top of the bridge pier or concrete column, thereby grinding the top of the bridge pier or concrete column. This effectively removes the concrete hardening burrs on the top of the bridge pier or concrete column, ensuring grinding efficiency.

[0040] When it is necessary to create a bevel angle on the outer top of a bridge pier or concrete column, the first hydraulic cylinder 103 operates to extend the first hydraulic telescopic rod 104, which in turn causes the first limiting circular plate 105 to descend. This then pushes the adjusting device 5 downwards, causing the rotating adjusting block 409 to rotate relative to the first rotating positioning block 405 and the second rotating positioning block 4014 under the positioning of the first rotating positioning rod 408 and the second rotating positioning rod 4013. During the rotation of the rotating adjusting block 409, the telescopic guide rod 505 and the second limiting circular plate 506 extend beyond the inner side of the telescopic positioning rod 504. Then, according to the actual situation... The tilt angle of the rotating adjustment block 409 needs to be adjusted to create a bevel angle. Then, the second servo motor 207 drives the transmission gear 208 to rotate, which in turn drives the adjustment device 3 to rotate. This causes the arc-shaped push groove 304 to rotate and push the first positioning rod 401 to spread out to the outermost side. Then, the bottom of the grinding assembly 6 is adjusted. Then, the first servo motor 201 drives the positioning groove grinding device 4 to rotate and simultaneously drives the positioning groove grinding device 4 to move inward. This completes the bevel angle creation work on the bridge pier or concrete column, making it convenient to create a bevel angle using the same equipment after burr grinding, which is convenient for users.

[0041] To create a positioning groove on the top of a bridge pier or concrete column, the first hydraulic cylinder 103 extends the first hydraulic telescopic rod 104, which in turn lowers the adjusting and pushing device 5. This causes the rotating adjusting block 409 to be perpendicular to the bottom of the first rotating positioning block 405 and the top of the second rotating positioning block 4014. The second servo motor 207 pushes the positioning groove grinding device 4 to spread outward to its maximum extent. Then, by adjusting the distance between the bottom of the grinding assembly 6 and the top of the bridge pier or concrete column, the first servo motor 201 drives the positioning groove grinding device 4 to rotate, while the second servo motor 207 drives the positioning groove grinding device 4 to move closer together, thus completing the creation of the positioning groove. This ensures that the center of the created positioning groove overlaps with the center of the bridge pier or concrete column, guaranteeing that the created positioning groove can fit well with the prefabricated module.

[0042] When the length of the rotating adjusting block 409 is insufficient when opening the positioning groove or slope, the positioning bolt 604 can be removed, and then the adjusting grinding plate 603 can be removed and installed at the second positioning notch 4012 to extend the guide hole 402. This facilitates the adjustment of the equipment according to actual needs, allowing the equipment to adapt to more construction situations. The equipment can also be moved to another pier or concrete column by pushing, making it easy to replace the pier or concrete column, thus ensuring the feeding efficiency of the equipment.

[0043] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
