Description

Technical Field

[0001] The invention relates to the technical field of cement pole production, in particular to a burr removal device for cement pole production. Background Art

[0002] Cement poles are mainly composed of steel bars and concrete, so they are also called reinforced concrete cement poles. They are mainly used as wire support in the power, communication, railway, petroleum and other industries. The production process is as follows: straighten the steel wire; generally arrange 8 to 12 straight steel wires in each pole mold, and use fine steel wire to coil the weft into a loop, and tie the joints with iron wire to make the keel of the cement pole; fill it with a certain proportion of cement; cover the upper mold after filling it with cement, and plug the two ends with gags; use a crane to lift the mold to the centrifuge, and the centrifuge rotates at a certain speed for a certain time. Through the centrifuge, the cement is attached to the surroundings to make a hollow cement pole; steam the cement pole with high-temperature steam in a steamer for a period of time to accelerate the solidification of the cement; after demoulding, the basic production of the cement pole is completed.

[0003] However, after the cement pole is manufactured, because the cement pole is formed by a mold that is snapped in half, there will be burrs on the surface of the cement pole along its length, that is, long strips of burrs remain at the joint of the mold, and the burrs need to be removed before the final factory use. The traditional method mainly relies on operators to use a handheld grinder for grinding, but this method has problems such as uneven grinding, low efficiency, and high labor costs. In the invention patent announcement number CN112935989A, a burr removal device for cement pole production is disclosed, including a door frame and a mounting block, a limit slide bar is installed between the door frames, and a sliding block is arranged on the outer side of the limit slide bar, a through hole is opened on the sliding block, and the sliding block is slidably connected to the limit slide bar through the through hole, a stepper motor is installed at one end of the top of the sliding block, and a driving gear is installed at the output end of the stepper motor, and a driven gear meshing with the driving gear is arranged on one side of the driving gear, and the driven gear is arranged at the top of the sliding block. The present invention is equipped with a drive motor, a grinding disc, a stepper motor, a driving gear, a driven gear and a tooth groove. Automatic grinding is achieved through the drive motor, and left and right reciprocating lateral movement is achieved through the meshing relationship between the stepper motor and the gear, which further improves the automation of the device, does not require manual assistance, and the lateral grinding effect is more uniform and smooth, thereby improving the effect and efficiency of grinding. However, in actual work of this invention, the grinding disc is installed at the lower end of the door frame and placed at the lower end of the cement pole. Although no manual operation is required during grinding, only one side can be ground first each time, and the other side can be ground after flipping, which has low production efficiency.

[0031] In a specific embodiment, Figures 1 to 6As shown, a burr removal device for cement pole production includes a frame 1. The frame 1 is composed of a placement table and support columns. The support columns are located at the four corners of the placement table. A plurality of support frames are evenly arranged at the lower end of the length direction of the placement table. The support frames are located between the support columns and support the placement table at the upper end together with the support columns. A positioning assembly 2 for positioning the cement pole is provided on the upper end surface of the frame 1. The positioning assembly 2 is provided with a plurality of groups and is evenly arranged along the length direction of the frame 1. Vertical plates 8 are provided on both sides of the width direction of the frame 1. The vertical plates 8 are vertically arranged. A crossbeam 9 is provided between the vertical plates 8. Both ends of the crossbeam 9 are fixedly installed on the top of the vertical plates 8 on both sides. The vertical plates 8 and the crossbeam 9 are connected by welding or integral molding. The vertical plates 8 reciprocate along the length direction of the frame 1 through the first drive assembly 7. The first drive assembly 7 is arranged at the lower end of the frame 1.

[0032] In a specific embodiment, Figures 1 to 6As shown, the positioning assembly 2 includes a positioning block 201, a positioning plate 202 and a lifting assembly 205. The positioning block 201 is a V-shaped structure, which is suitable for placing cement poles of different sizes. Positioning plates 202 are arranged on the inclined surfaces on both sides of the positioning block 201, and a rotating column 203 is arranged on the back of the positioning plate 202. The rotating column 203 and the positioning plate 202 are an integrated structure.

A second spring (not shown in the figure) is arranged on both sides of the positioning plate 202. When the positioning plate 202 rotates, it will not be directly touched on the positioning block 201 under the action of gravity, so as to avoid damage to the positioning plate 202 and play a buffering role. The cement pole has a certain inclination. After the positioning plate 202 is placed on the cement pole, the positioning plate 202 rotates along the rotation axis 204 according to different forces, and the end face of the positioning plate 202 fits with the outer circle of the cement pole, which is used to support and position the cement pole. The first group of positioning components 2 is fixedly installed at the front end of the frame 1, and the lower end of each group of positioning components 2 at the rear end is independently provided with a lifting component 205, and the lifting component 205 separately adjusts the height of the corresponding positioning component 2. The lifting component 205 is placed on the upper end face of the frame 1 according to the inclination and specifications of the cement pole. After the cement pole is placed on the positioning component 2 at the front end, the lifting components 205 at the rear end are adjusted respectively so that each positioning component 2 fits with the outer circle of the cement pole, which is used to place the cement pole stably.

[0033] In a specific embodiment, Figures 1 to 6 As shown, the lifting assembly 205 includes a base 2051, a top plate 2052, at least two groups of X-shaped cross-hinged connecting rods 2053 and a hydraulic cylinder 2055 for driving the connecting rods 2053 to move horizontally. The two groups of connecting rods 2053 are rotatably connected by a connecting rod 2056. The upper and lower ends of the front end of the X-shaped cross-hinged connecting rod 2053 are respectively hinged to the base 2051 and the top plate 2052, and the upper and lower ends of the rear end of the X-shaped cross-hinged connecting rod 2053 are respectively slidably connected to the base 2051 and the top plate 2052. The corresponding surfaces of the base 2051 and the top plate 2052 are fixedly installed with sliding rails 2054, the sliding rails 2054 are slidably connected to the connecting rod 2056, and the lower end connecting rod 2056 is rotatably connected to the hydraulic cylinder 2055, and the hydraulic cylinder 2055 is hingedly installed on the base 2051. The hydraulic cylinder 2055 drives the connecting rod 2056 to slide on the slide rail 2054, so that the top plate 2052 moves up and down, thereby driving the positioning block 201 to move up and down.

[0034] In a specific embodiment, Figures 1 to 6As shown, the grinding assembly 3 includes a grinding rod 301, a mounting seat 302, a fixing plate 303, a first cylinder 304, and a slider 305. The mounting seat 302 has a "C" - shaped structure, and rotating shafts 306 are provided on the inner sides of its upper and lower legs. The grinding rod 301 is vertically arranged, and both ends are detachably installed in the mounting seat 302 through the rotating shafts 306. The rotating shafts 306 are connected to both ends of the grinding rod 301 through a clamping assembly 6. The clamping assembly 6 can quickly fix and disassemble the rotating shafts 306 and the grinding rod 301, improving the maintenance efficiency. A third motor 307 is provided on the top of the mounting seat 302, and the output end of the third motor 307 is fixedly connected to the rotating shaft 306 on the side close to the third motor 307. The third motor 307 drives the rotating shaft 306 to rotate, so that the grinding rod 301 continuously grinds the burrs on the side of the cement pole during rotation, improving the grinding accuracy. A fixing plate 303 is provided on the back of the mounting seat 302. The fixing plate 303 is slidably connected to the mounting seat 302 by screws. A first cylinder 304 is provided at the upper end of the fixing plate 303. The first cylinder 304 drives the fixing plate 303 to move up and down. The first cylinder 304 is fixedly installed at the lower end of the slider 305. The position of the grinding rod 301 can be adjusted up and down according to the specifications of the cement pole, and by adjusting the grinding rod 301 up and down through the first cylinder 304, the utilization rate of the grinding rod 301 is improved. The slider 305 is slidably installed in the chute of the cross - beam 9 and is driven by a second driving assembly 5 to move closer to or away from each other on both sides.

[0035] In a specific embodiment, as Figures 1 to 6 shown, the second driving assembly 5 includes a bidirectional lead screw 501 and a second motor 502. Both ends of the bidirectional lead screw 501 are rotatably installed in the chute inside the cross - beam 9. The bidirectional lead screw 501 is threadedly connected to the slider 305. One end of the bidirectional lead screw 501 extends out of the cross - beam 9 and is fixedly connected to the output shaft of the second motor 502. The bidirectional lead screw 501 passes through the slider 305 and is screwed to the slider 305. Since the sizes of both ends of the cement pole are inconsistent, during the grinding process, according to the change in the outer diameter of the cement pole, the slider 305 is driven to make the positions of the grinding rod 301 on both sides of the cement pole the same, ensuring the grinding accuracy and improving the grinding efficiency. A laser rangefinder (not shown in the figure) is used at the installation plate to monitor the outer diameter of the cement pole in real - time. According to the monitoring data, the second motor 502 is automatically controlled by a PLC to start, thereby adjusting the position of the grinding assembly 3 and reducing manual intervention.

[0036] Specifically, the grinding rod 301 is made of diamond - coated or grinding wheel material for efficiently removing burrs.

[0037] In a specific embodiment, as Figures 1 to 6As shown, the dust collection assembly 4 includes a dust collection hood 401, a dust collection duct 402 and a dust collector 403. The dust collection hood 401 is arranged on both sides of the mounting seat 302 and is fixedly connected to the mounting seat 302 through a bracket. The opening direction of the dust collection hood 401 is toward the direction of mutual friction between the grinding rod 301 and the cement rod. The dust collector 403 is fixedly installed at the lower end of the frame 1, and the dust collector 403 and the dust collection hood 401 are connected through the dust collection duct 402. The dust collection hood 401 is a trumpet-shaped structure, and the trumpet-shaped cement rod and the tangent direction of the grinding rod 301 when grinding are used to collect dust generated during the grinding process to keep the working environment clean. The dust collection duct 402 here is a retractable hose. When the dust collection hood 401 moves with the grinding assembly 3, the dust collection duct 402 can be stretched or retracted.

The front end of the guide plate 309 is fixedly installed at the rear end of the fixed plate 303, so that the fixed plate 303 moves along the direction of the guide groove when moving up and down. When the guide plate 309 is installed in the guide groove, the grinding assembly 3 is twisted under the action of force when grinding the cement pole, which affects the quality of grinding.

[0039] In a specific embodiment, Figures 1 to 6 As shown, a plurality of first springs 308 are provided between the mounting seat 302 and the fixing plate 303. The first springs 308 are sleeved on the screws, so that there is a certain elasticity between the mounting seat 302 and the fixing plate 303. The screws pass through the fixing plate 303 and are connected to the mounting seat 302. The screws can move in the fixing plate 303 to adjust the position of the mounting seat 302. The first springs 308 are provided between the mounting seat 302 and the fixing plate 303 to buffer the vibration generated by the grinding rod 301 during the grinding of the cement pole, thereby improving the grinding accuracy.

[0040] In a specific embodiment, Figures 1 to 6 As shown, the clamping assembly 6 includes a movable clamping block 601 and a fastening nut 602. The movable clamping block 601 is provided with two pieces and is symmetrically installed at the lower end of the rotating shaft 306. A through slot is horizontally opened on the rotating shaft 306. The movable clamping block 601 is rotatably installed on both sides of the through slot through a fixing pin. A tension spring 603 is provided between the two movable clamping blocks 601. The two ends of the tension spring 603 are respectively connected to the inner sides of the two movable clamping blocks 601 so that they open naturally. Slots are provided at both ends of the grinding rod 301, and the movable clamping block 601 is installed in the slots. The fastening nut 602 is threadedly connected to the ends of the rotating shaft 306 and the grinding rod 301, respectively, for fixing the grinding rod 301.

[0041] Specifically, the fastening nut 602 is rotated upward, and the active clamping block 601 is disengaged from the clamping slot of the polishing rod 301 under the action of the tension spring 603, so that the polishing rod 301 can be removed. The fastening nut 602 is rotated in the opposite direction, and the fastening nut 602 presses the active clamping block 601 inward, so that the front end of the active clamping block 601 is clamped in the clamping slot of the polishing rod 301, thereby preventing the polishing rod 301 from falling off the rotating shaft 306. This structure can quickly fix and remove the polishing rod 301, thereby improving maintenance efficiency.
