On the contrary, the embodiments of the present utility model include all changes, modifications and equivalents falling within the spirit and connotation of the appended claims.

[0025] The column grinding device according to the embodiment of the present utility model will be described below with reference to the drawings.

[0026] As Figures 1 - 6 shown, the column grinding device according to the embodiment of the present utility model includes a semi-circular ring plate 1, a grinding mechanism 2, a driving mechanism 3, a clamping and supporting mechanism 4 and a locking mechanism 5.

[0027] Among them, two semi-circular ring plates 1 are provided, and the semi-circular ring plates 1 are pivotally connected to each other. A semi-circular ring groove 11 is formed in the semi-circular ring plate 1, and a semi-tooth ring 12 is arranged in the semi-circular ring groove 11.

[0028] It should be noted that two semi - circular ring plates 1 can be combined into a circular ring plate. The semi - circular ring plates 1 are pivotally connected through a rotating fastener. The rotating fastener can be composed of an extension plate and a rotating shaft in combination. The semi - circular ring plate 1 rotates by relying on the extension plate connected to the rotating shaft. There are two semi - tooth rings 12 and two semi - annular grooves 11. The two semi - annular grooves 11 can be combined into a complete annular groove, and the two semi - tooth rings 12 can be combined into a complete tooth ring. The tooth ring can rotate in the annular groove.

[0029] Optionally, to improve the stability of the rotation of the semi - tooth ring 12 in the semi - annular groove 11, semi - annular limiting strips can be provided at the top and bottom of the semi - tooth ring 12, and semi - annular limiting grooves used in combination with the limiting strips can be provided on the top and bottom surfaces of the semi - annular groove 11 to ensure the stability of the semi - tooth ring 12. In the combined state, bumps and grooves can be provided at both ends of the semi - tooth ring 12, and the stability of the combination of the semi - tooth ring 12 can be further improved by engaging the bumps in the grooves.

[0030] Among them, the grinding mechanism 2 is arranged on the semi - circular ring plate 1, and the grinding mechanism 2 is connected to the semi - tooth ring 12.

[0031] It can be understood that the grinding mechanism 2 is connected to the semi - tooth ring 12. When the semi - tooth rings 12 are combined into a complete tooth ring and rotate, the grinding mechanism 2 can be driven to rotate to perform uniform grinding on the surface of the column.

[0032] Among them, the driving mechanism 3 is arranged on the semi - circular ring plate 1; the clamping and supporting mechanism 4 is arranged at the bottom of the driving mechanism 3. The clamping and supporting mechanism 4 includes a main driver 41, a backing plate 42 and a clamping structure 43. Among them, the top of the main driver 41 is connected to the driving mechanism 3, the backing plate 42 is connected to the bottom end of the main driver 41, and the clamping structure 43 is arranged on both sides of the backing plate 42.

[0033] It should be noted that the driving mechanism 3 is connected to the semi - circular ring plate 1, and then drives the semi - tooth ring 12 in the semi - circular ring plate 1 to control the rotation of the grinding mechanism 2 for grinding. The main driver 41 is a multi - stage electric control telescopic rod, and the telescopic end is connected to the driving mechanism 3 through a fastener. The fastener can be a combination of a screw and a bolt with a connecting plate member.

[0034] It can be understood that the driving mechanism 3 drives the semi - tooth ring 12, the main driver 41 controls the lifting or lowering of the driving mechanism 3 and the semi - circular ring plate 1, the backing plate 42 supports the device and fits on the ground, and the clamping structure 43 can clamp and fix the device on the column to provide the operating stability of the device.

[0035] Among them, the locking mechanism 5 is arranged on the semi - circular ring plate 1.

[0036] It can be understood that the locking mechanism 5 provides connection stability when the semi - circular ring plates 1 are combined into a circular ring plate, preventing the semi - circular ring plates 1 from separating and disintegrating by themselves during the grinding process.

[0037] Specifically, the relevant staff use the clamping structure 43 to clamp and fix the device beside the column. One semi-circular ring plate 1 is attached to the column, and the other semi-circular ring plate 1 is rotatably sleeved on the column. After combining the two semi-circular ring plates 1 into a circular ring plate, it is locked and reinforced through the locking mechanism 5. The driving mechanism 3 is operated to drive the semi-tooth ring 12 to drive the grinding mechanism 2 to rotate to evenly grind the surface of the column, and the main driver 41 is operated to drive the grinding mechanism 2 to lift and grind the high part of the column.

[0038] In an embodiment of the present invention, as Figure 1 、 Figure 2 and Figure 4 shown, the grinding mechanism 2 includes an arc-shaped support plate 21, a sleeve 22, a telescopic column 23, a grinding disc 24, a baffle 25 and a spring 26.

[0039] Among them, one end of the arc-shaped support plate 21 is connected to the semi-circular ring plate 1, the sleeve 22 is arranged at the other end of the arc-shaped support plate 21, the inside of the sleeve 22 is a cavity structure, the telescopic column 23 is arranged in the sleeve 22 and one end extends to the outside thereof, and the grinding disc 24 is arranged at the other end of the telescopic column 23.

[0040] It can be understood that the telescopic column 23 is arranged in the sleeve 22 and can be telescopic. The arc-shaped support plate 21 is connected to the sleeve 22, and the arc-shaped support plate 21 is also connected to the semi-tooth ring 12. When the semi-tooth ring 12 rotates, it can drive the arc-shaped support plate 21 and the sleeve 22 to rotate accordingly. The telescopic column 23 is connected to the grinding disc 24, and the above connections can all be connected through fasteners. The telescopic column 23 extends and retracts to push the grinding disc 24 against the surface of the column, and the grinding disc 24 rotates with the rotation of the sleeve 22 and the telescopic column 23 to evenly grind the surface of the column.

[0041] Among them, the baffle 25 is arranged in the sleeve 22, the baffle 25 fits against the inner wall of the sleeve 22, one end of the baffle 25 is connected to one end of the telescopic column 23, and the spring 26 is arranged at the other end of the baffle 25.

[0042] It should be noted that the inside of the sleeve 22 is a cavity structure for accommodating the baffle 25. The baffle 25 fits against the inner wall of the sleeve 22 and is connected to the telescopic column 23. The telescopic column 23 can be restricted through the baffle 25 to prevent the telescopic column 23 from separating from the sleeve 22. The spring 26 is arranged in the sleeve 22 to push the baffle 25 and the telescopic column 23, providing a pushing force for the telescopic column 23 to push the grinding disc 24, ensuring that the grinding disc 24 can closely fit against the surface of the column to complete the grinding work.

[0043] Specifically, the semi-circular ring plates 1 are combined into a circular ring plate and sleeved on the column. Under the influence of the reaction force of the spring 26, the grinding disc 24 closely fits against the column and rotates following the connection of the arc-shaped support plate 21, the sleeve 22 and the telescopic column 23, and closely grinds the surface of the column.

[0044] In an embodiment of the present utility model, as Figure 1 and Figure 3 shown, the driving mechanism 3 includes a connecting seat 31, a gear 32 and a motor 33.

[0045] Among them, one end of the connecting seat 31 is connected to the semi-circular ring plate 1. The inside of the connecting seat 31 is a cavity structure. The gear 32 is rotatably arranged in the connecting seat 31. The gear 32 is meshed and connected with the semi-tooth ring 12. The motor 33 is arranged on the connecting seat 31, and the bottom end of the motor 33 is connected to the gear 32.

[0046] It can be understood that the gear 32 is arranged on the connecting seat 31. The connecting seat 31 is connected to the semi-circular ring plate 1. The gear 32 is meshed with the semi-tooth ring 12. The rotation of the gear 32 can drive the semi-tooth ring 12 to rotate accordingly. The semi-tooth rings 12 are combined into a complete tooth ring and rotate in the semi-circular groove 11 to drive the grinding mechanism 2 to rotate accordingly. The motor 33 is connected to the gear 32 to drive the rotation of the gear 32.

[0047] Specifically, the relevant personnel start the motor 33. The motor 33 drives the gear 32 in the connecting seat 31 to rotate. The gear 32 drives the semi-tooth ring 12 meshed with it to rotate, and further drives the grinding mechanism 2 to rotate to grind the upright column.

[0048] In an embodiment of the present utility model, as Figure 1 and Figure 5 shown, the clamping structure 43 includes a horizontal support plate 431, a bent clamping plate 432, a rotating rod 433 and a torsion spring 434.

[0049] Among them, the horizontal support plate 431 is connected to the backing plate 42. The bent clamping plate 432 is arranged at the bottom of the horizontal support plate 431. The rotating rod 433 is arranged at the bottom end of the horizontal support plate 431. A rotating groove is formed in the bent clamping plate 432. The bottom end of the rotating rod 433 is rotatably connected to the bottom surface of the rotating groove. The torsion spring 434 is sleeved on the rotating rod 433. The top surface and the bottom surface of the torsion spring 434 are respectively connected to the horizontal support plate 431 and the bottom surface of the rotating groove.

[0050] It should be noted that the horizontal support plate 431, the bent clamping plate 432, the rotating rod 433 and the torsion spring 434 are all provided in two groups, which are arranged on both sides of the backing plate 42. The above-mentioned components on both sides are required to cooperate to clamp the upright column. The bending structure of the bent clamping plate 432 can also more conveniently fit on the surface of the upright column for clamping.

[0051] It can be understood that the transverse support plate 431 and the bending clamp plate 432 are connected by means of the rotating rod 433, and also by means of the rotating connection between the rotating rod 433 and the rotating groove of the bending clamp plate 432, so that the bending clamp plate 432 can rotate on the transverse support plate 431 to realize the basis of clamping. A torsion spring 434 is arranged in the rotating groove, and the torsion spring 434 is connected to the bottom surface of the rotating groove and the transverse support plate 431 through fasteners. The torsion spring 434 provides a torsional force for the bending clamp plate 432 to rotate, and the torsional force is converted into a clamping force to clamp the column when clamping.

[0052] Specifically, the relevant staff will pry the bending splints 432 apart in the direction away from each other, and then push them to the positions on both sides of the column, release their hands, and with the help of the torsion of the torsion spring 434, the bending splints 432 rotate according to the rotating rod 433 and the horizontal support plate 431, and the bending splints 432 on both sides are tightly clamped on the column.

[0053] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the locking mechanism 5 includes a locking block 51 and a locking catch 52 .

[0054] The locking block 51 is arranged at one end of the semicircular ring plate 1 , a locking groove is provided on the locking block 51 , and the locking buckle 52 is a U-shaped structure, and the locking buckle 52 is engaged in the locking groove.

[0055] It can be understood that the locking groove on the locking block 51 matches the locking buckle 52, and the locking buckle 52 is a U-shaped structure that can be inserted into the locking grooves on the two locking blocks 51 and snapped together, so that the two locking blocks 51 are connected together and cannot be easily separated, thereby achieving the locking function.

[0056] Specifically, after the relevant personnel assemble the semicircular ring plate 1 into a completed circular ring plate, they buckle the lock buckle 52 into the lock groove on the lock block 51, and connect and merge the lock block 51, so that the semicircular ring plate 1 cannot be easily separated.

[0057] In summary, the column grinding device of the embodiment of the utility model can rotate and grind on the column until it grinds every part of the column surface, and the grinding is uniform. It can be fixed next to the column and freely raised and lowered in height, and can grind the high area of the column.
