[0002] Foundation columns are needed during the construction of power engineering projects. In order to improve the stability of the foundation columns, a chamfering device is needed to chamfer the foundation columns before installation.

[0003] Existing chamfering devices typically use an arc-shaped bending plate to rub the edge of the foundation column, grinding the edge into an arc shape. However, because the center of the arc of the bending plate cannot be located, the grinding degree of the vertical and horizontal surfaces of the foundation column is inconsistent, resulting in non-standard grinding of the foundation column edges. This leads to poor load-bearing capacity and stability of the foundation column, seriously affecting the long-term stable operation of the substation. Therefore, there is a need to provide a chamfering device for the construction of foundation columns in power transmission and transformation projects. Summary of the Invention

The side of the rotating column is higher than the opening of the receiving groove.

[0008] Furthermore, a slot is provided on the upper inner side of the chamfered plate, and a protrusion is provided on the upper end of the limiting block, the protrusion being inserted into the slot.

[0009] Furthermore, the chamfering plate is disposed on the driven plate, the driven plate is slidably disposed on the turntable, the driven plate and the chamfering plate correspond one-to-one, and the adjustment mechanism adjusts the driven plate to synchronously retract or separate.

[0010] Furthermore, the number of driven plates is six, and the chamfered surfaces of the six chamfered plates form a cylindrical chamfered space with a hemispherical bottom surface. The chamfered plates are evenly distributed.

[0011] Furthermore, the adjusting mechanism includes a stud, a threaded sleeve at the bottom of the turntable, the upper end of the stud being threaded into the threaded sleeve, and a hexagonal adjusting block fixedly mounted at the lower end of the stud. Each side of the adjusting block is provided with a screw rod, the free end of which is threadedly connected to a mounting block. The turntable has driven plate slots, each corresponding to a driven plate. The lower end of the driven plate passes through the driven plate slot and slides along the length of the driven plate slot. The end has a sliding slot, the angle between the sliding slot and the turntable is α, 30°≤α≤60°, a movable rod passes through the sliding slot and slides along the length of the sliding slot, the two ends of the movable rod are respectively threaded to two adjacent mounting blocks, the movable rod is provided with two stop blocks, the size of the stop blocks is larger than the size of the sliding slot, the driven plate is located between the two stop blocks, there is a gap between the stop blocks and the corresponding side of the driven plate, and the mounting block is provided with a receiving space to accommodate the stop blocks.

[0012] Furthermore, the lower end of the stud passes through the adjusting block, and a handle is provided at the lower end of the stud.

[0013] Furthermore, two opposing sliding grooves are provided at both the upper and lower ends of the driven plate slot, and the sliding grooves are arranged along the length direction of the driven plate slot. Two opposing sliding rods are provided at both the upper and lower ends of the driven plate on the turntable, and the sliding rods correspond one-to-one with the sliding grooves. An installation groove is provided on the opposite surface of the sliding rod and the corresponding sliding groove.

[0016] The beneficial effects of this invention are as follows: The chamfering device used in the construction of foundation columns for power transmission and transformation projects involves placing the chamfered end of the foundation column into the chamfered space formed by the chamfered surfaces during chamfering. The adjustment mechanism is then used to ensure that the sidewall of the foundation column contacts each rotating component, and the edge of the chamfered end contacts the chamfered surface. The drive mechanism is then activated, causing the turntable to rotate, which in turn rotates the chamfering plate. The chamfering plate then drives the chamfered surface to rotate synchronously. The chamfered surface repeatedly grinds and polishes the angular edge formed by the sidewall and bottom wall of the chamfered end of the foundation column, making the chamfered edge smooth. This completes the chamfering of the foundation column, avoiding abrupt protrusions at the chamfered edge, thereby reducing stress concentration at the chamfered end, ensuring uniform stress distribution, and improving the load-bearing capacity and stability of the foundation column. The sidewalls of the foundation column contact the rotating components, avoiding contact with the chamfering plate, thus reducing the friction between the foundation column and the chamfering plate. The foundation column contacts the chamfered surface, where the friction is greater, creating a speed difference for rapid chamfering. The sidewalls of the foundation column contact each rotating component, ensuring that the chamfered space formed by the foundation column and the chamfered surface is coaxial. The rotation of the chamfered surface synchronously and uniformly grinds the sidewalls and bottom wall of the chamfered end, resulting in high-quality chamfering. Therefore, this chamfering device for foundation column construction in power transmission and transformation projects provides high-quality, high-standard, and high-efficiency chamfering for foundation columns of different sizes, improving the load-bearing capacity and stability of the foundation columns, and ensuring the long-term stable and safe operation of substations.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, this embodiment provides a chamfering device for the construction of foundation columns in power transmission and transformation projects. It includes a base plate 1, on which a support rod 2 is mounted. An installation cylinder 4 is mounted on the upper end of the support rod 2. A turntable 5 and a driving mechanism for rotating the turntable 5 are rotatably mounted inside the installation cylinder 4. At least three chamfering plates 7 are slidably mounted on the turntable 5. A rotating component is mounted on the upper inner surface of each chamfering plate 7, and the lower inner surface of each chamfering plate 7 is an arc-shaped chamfered surface 701. The chamfered surfaces 701 form a chamfered space to accommodate the end of the foundation column. The turntable 5 is equipped with an adjustment mechanism for synchronously closing or opening the chamfering plates 7. The number of support rods 2 is at least two, such as two, three, four, or six. The support rods 2 are evenly distributed at the bottom of the installation cylinder 4. Support blocks 3 are mounted on the top of the support rods 2 to better support the installation cylinder 4. Each support block 3 corresponds to one support rod 2, and the installation cylinder 4 is mounted on the upper end of each support block 3. The chamfered plates 7 are evenly distributed around the circumference of the turntable 5, and the rotating component is a rotating column 8 or a rotating ball. The drive mechanism is a gear drive mechanism or a belt drive mechanism.

[0029] Based on the aforementioned chamfering device for the construction of foundation columns in power transmission and transformation projects, when chamfering the foundation column, the chamfered end of the foundation column is placed into the chamfering space formed by the chamfering surface 701. The adjustment mechanism is adjusted so that the side wall of the foundation column contacts each rotating component, and the edge of the chamfered end of the foundation column contacts the chamfering surface 701. The drive mechanism is activated, the turntable 5 rotates, driving the chamfering plate 7 to rotate. The chamfering plate 7 drives the chamfering surface 701 to rotate synchronously. The chamfering surface 701 repeatedly grinds and polishes the edge of the chamfered end of the foundation column, which is composed of the side wall and bottom wall, making the edge of the chamfered end of the foundation column smooth. The chamfering of the foundation column is completed, avoiding the situation of abrupt protrusion at the edge of the chamfered end of the foundation column, thereby reducing the stress concentration at the chamfered end of the foundation column, and ensuring that the chamfered end of the foundation column is subjected to uniform force, thus improving the load-bearing capacity and stability of the foundation column. The sidewall of the foundation column contacts the rotating component, avoiding contact with the chamfer plate 7, thus reducing the friction between the foundation column and the chamfer plate 7. The foundation column contacts the chamfer surface 701, where the friction is high, creating a speed difference for rapid chamfering. The sidewall of the foundation column contacts each rotating component, ensuring that the chamfer space formed by the foundation column and the chamfer surface 701 is coaxial. The rotation of the chamfer surface 701 synchronously and uniformly grinds the sidewall and bottom wall of the chamfer end, resulting in high-quality chamfering. Therefore, the chamfering device of this application for the construction of foundation columns in power transmission and transformation projects can chamfer foundation columns of different sizes and specifications with high quality, high standards, and high efficiency, improving the load-bearing capacity, seismic resistance, and stability of the foundation columns, and ensuring the long-term stable and safe operation of the substation.

[0030] Preferably, the rotating component is a rotating column 8, and a limiting block 9 is fixedly provided on the upper inner side of the chamfered plate 7. The limiting block 9 is provided with a receiving groove, and the rotating column 8 is vertically rotatably disposed in the receiving groove. The side of the rotating column 8 is higher than the opening of the receiving groove.

[0031] The receiving groove of the limiting block 9 serves to support and install the rotating column 8. The rotating column 8 rotates within the receiving groove, and the side of the rotating column 8 protrudes above the opening of the receiving groove, ensuring that the side wall of the foundation column is in contact with the rotating column 8. The rotating column 8 is cylindrical in shape, and when the foundation column is chamfered, the axis of the rotating column 8 is parallel to the axis of the foundation column. The limiting block 9 is fixedly or detachably installed on the upper end of the chamfering plate 7.

[0032] Specifically, the upper inner side of the chamfered plate 7 is provided with a slot 702, and the upper end of the limiting block 9 is provided with a protrusion, which is inserted into the slot 702.

[0033] The protrusion at the upper end of the limiting block 9 is securely inserted into the slot 702 at the upper end of the chamfer plate 7, ensuring that the limiting block 9 and the chamfer plate 7 are firmly fixed. The plug-in detachable method facilitates installation and disassembly.

[0034] In one possible implementation, the chamfering plate 7 is disposed on the driven plate 6, the driven plate 6 is slidably disposed on the turntable 5, the driven plate 6 and the chamfering plate 7 correspond one-to-one, and the adjustment mechanism adjusts the driven plate 6 to synchronously retract or separate.

[0035] The driven plate 6 provides better load-bearing support for the chamfering plate 7, reduces deformation of the chamfering plate 7, and extends the service life of the chamfering device. The number of driven plates 6 is three, four, six, or more, and the driven plates 6 are evenly distributed in a circle on the turntable 5.

[0036] Preferably, there are six driven plates 6, and the chamfered surfaces 701 of the six chamfered plates 7 form a cylindrical chamfered space with a hemispherical bottom surface. The chamfered plates 7 are evenly distributed.

[0037] Six driven plates 6 are evenly distributed on the turntable 5 at equal intervals around the circumference. The cylindrical chamfered space formed by the chamfered surfaces 701 provides better coverage for the foundation column, ensuring that the foundation column and the chamfered space formed by the chamfered surfaces 701 are coaxial, thereby making the chamfered edge of the foundation column more uniform and faster.

[0038] In one possible implementation, the adjusting mechanism includes a stud 20, a threaded sleeve 24 is provided at the bottom of the turntable 5, the upper end of the stud 20 is threaded into the threaded sleeve 24, a regular hexagonal prism-shaped adjusting block 21 is fixedly provided at the lower end of the stud 20, and screws 18 are provided on the sides of the adjusting block 21. The free end of the screws 18 is threadedly connected to a mounting block 17. The turntable 5 has a driven plate slot 12, which corresponds one-to-one with a driven plate 6. The lower end of the driven plate 6 passes through the driven plate slot 12, and the driven plate 6 slides along the length direction of the driven plate slot 12. The lower end of the driven plate 6 has an opening... A sliding slot 601 is provided, with an angle α between the sliding slot 601 and the turntable 5, where 30°≤α≤60°. A movable rod 22 passes through the sliding slot 601 and slides along the length of the sliding slot 601. The two ends of the movable rod 22 are threadedly connected to two adjacent mounting blocks 17. The movable rod 22 is provided with two stop blocks 26, the size of which is larger than the size of the sliding slot 601. The driven plate 6 is located between the two stop blocks 26, and there is a gap between the stop blocks 26 and the corresponding sides of the driven plate 6. The mounting block 17 is provided with a receiving space 1701 to accommodate the stop blocks 26. A middle plate 19 is provided on the screw 18, with the threads on both sides of the middle plate 19 having opposite helical directions. The middle plate 19 and the screw 18 rotate synchronously. The mounting block 17 remains horizontal and close to the adjusting block 21, and the mounting block 17 and the adjusting block 21 are located on the same horizontal plane. The free end of the screw 18 is the other end connected to the adjusting block 21, and the mounting block 17 has a screw hole 1702 that is threadedly connected to the screw 18.

[0039] When chamfering the foundation column, if the opening of the chamfering space is larger than the diameter of the chamfered end of the foundation column, the chamfered end of the foundation column is placed in the chamfering space. Rotating the stud 20 downwards moves the adjusting block 21 downwards, causing the movable rod 22 to move downwards along the sliding slot 601. This causes the driven plate 6 to move synchronously towards the center of the turntable 5 along the driven plate slot 12, converging closer together. The sidewall of the foundation column is in contact with each rotating column 8, and the edge of the chamfered end of the foundation column abuts against the chamfered surface 701. Rotating the stud 20 stops, and the drive mechanism is activated, driving the turntable 5 to rotate. The chamfered surface 701 repeatedly grinds and polishes the edge of the chamfered end of the foundation column, completing the chamfering. Reversing the rotation, the stud 20 moves upwards, moving the adjusting block 21 upwards, causing the movable rod 22 to move upwards along the sliding slot 601, causing the driven plate 6 to move upwards along the driven plate slot 12. 2. Move synchronously away from the center of turntable 5, separating the base column. The side wall of the base column separates from each rotating column 8, and the chamfered edge of the base column separates from the chamfered surface 701. Remove the base column. When the opening of the chamfered space is smaller than the diameter of the chamfered end of the base column, rotate stud 20 upward. The driven plate 6 moves away synchronously, and the opening of the chamfered space becomes larger. Place the base column in. Rotate stud 20 downward in the opposite direction. The driven plate 6 moves closer and closes synchronously. The side wall of the base column fits against each rotating column 8. The chamfered edge of the base column abuts against the chamfered surface 701. Stop rotating stud 20, start the drive mechanism, and drive turntable 5 to rotate. The chamfered surface 701 repeatedly grinds and polishes the chamfered edge of the base column to complete the chamfering. Rotate stud 20 upward in the opposite direction. The driven plate 6 moves away synchronously, and remove the base column. The included angle between the sliding slot 601 and the turntable 5 is α, where 30°≤α≤60°, such as 30°, 45°, or 60°, etc. Further, the included angle between the sliding slot 601 and the turntable 5 is 45°. During the upward and downward rotation of the stud 20, the stud 20 is located inside the threaded sleeve 24. The length of the threaded sleeve 24 can be specifically selected according to the size of the foundation column. To prevent the stud 20 from unscrewing out of the threaded sleeve 24, a baffle can be installed on the inner side of the lower end of the threaded sleeve 24. The size of the stop block 26 is larger than the width of the sliding slot 601, and the stop block 26 cannot pass through the sliding slot 601. The driven plate 6 is located between the two stop blocks 26, and there is a gap between the corresponding sides of the stop blocks 26 and the driven plate 6 to ensure that the driven plate 6 retracts or separates synchronously, while ensuring the integrity of the chamfering device.

[0040] Preferably, the lower end of the stud 20 passes through the adjusting block 21, and a handle 25 is provided at the lower end of the stud 20.

[0041] The handle 25 allows the operator to easily rotate the stud 20 by applying force with the grip when adjusting the adjusting block 21.

[0042] In one possible implementation, two opposing sliding grooves 13 are provided at both the upper and lower ends of the driven plate slot 12. The sliding grooves 13 are arranged along the length direction of the driven plate slot 12. Two opposing sliding rods 14 are provided at both the upper and lower ends of the driven plate 6 located on the turntable 5. The sliding rods 14 correspond one-to-one with the sliding grooves 13. The opposite surfaces of the sliding rods 14 and the corresponding sliding grooves 13 are provided with mounting grooves. The mounting grooves are opposite to the corresponding sliding grooves 13. The width of the mounting groove is the same as the width of the corresponding sliding groove 13. A rolling ball 23 is rolled in the mounting groove. The rolling ball 23 is located between the corresponding mounting groove and the sliding groove 13. There is a gap between the mounting groove and the corresponding sliding groove 13.

[0043] Two opposing grooves 13 are provided on the upper part of the turntable 5 near each driven plate slot 12. Two opposing grooves 13 are provided on the lower part of the turntable 5 near each driven plate slot 12. Two opposing sliding rods 14 are provided on the driven plate 6 at the upper part of the turntable 5 and at the lower part of the turntable 5. The sliding rods 14 correspond one-to-one with the grooves 13. The opposite surfaces of the sliding rods 14 and the corresponding grooves 13 are provided with mounting grooves. Rolling balls 23 are provided in the mounting grooves. The mounting groove covers the grooves 13. The grooves 13, rolling balls 23 and sliding rods 14 roll in cooperation. The rolling balls 23 roll along the length of the grooves 13, which is more conducive to the driven plate 6 moving back and forth along the length of the driven plate slot 12, ensuring that the adjustment mechanism drives the driven plate 6 to run synchronously and smoothly.

[0044] The driving mechanism is a gear driving mechanism, which includes a servo motor 16. The output end of the servo motor 16 is provided with a small gear 15. The turntable 5 is fixedly provided with a rotating drum 10. A large gear 11 is fixedly sleeved on the outside of the rotating drum 10. The small gear 15 and the large gear 11 are connected by gear transmission.

[0045] Servo motor 16, in conjunction with large gear 11 and small gear 15, drives the rotating drum 10 to rotate, thereby causing the rotating drum 10 to drive the turntable 5 to rotate synchronously. The sizes of large gear 11 and small gear 15 are relative, and large gear 11 has a through hole in the middle. The servo motor 16 is powered by an external power supply. The rotating drum 10 is fixedly sleeved with large gear 11, such as by welding. The rotating drum 10 is fixedly mounted on the upper end of the turntable 5. The turntable 5 and the rotating drum 10 form a cylinder with a closed lower end. There is a gap between large gear 11 and mounting cylinder 4. The lower end of the cylinder is rotatably connected inside the mounting cylinder 4, and the upper end of the cylinder is fixedly sleeved inside the through hole of large gear 11.

[0046] As one possible implementation, the chamfered surface 701 is provided with a plurality of grooves at equal intervals, and the grooves are arranged from top to bottom along the arc surface of the chamfered surface 701.

[0047] The chamfered surface 701 is composed of multiple equally spaced grooves. The grooves cover the inner arc surface of the lower end of the chamfered plate 7. The chamfered surface 701 with its groove structure is simple and facilitates grinding and polishing of the chamfered edge of the foundation column.

Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
