Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1 to 6, the utility model comprises two sleeves 1 with axes arranged along the left-right direction, wherein the two sleeves 1 are arranged coaxially and at left-right intervals, a plurality of radial threaded rods 2 are uniformly distributed on the side wall of each sleeve 1 in a circumferential manner, the inner end of each threaded rod 2 penetrates into the sleeve 1, the depth of the inner end of each threaded rod 2 extending into the sleeve 1 can be adjusted by screwing the threaded rod 2, a rectangular block 3 is arranged at the inner end of each threaded rod 2, and a grinding disc 4 is attached to the inner end of each rectangular block 3; the two sleeves 1 can synchronously rotate in opposite directions.
In order to realize synchronous reverse rotation of the two sleeves 1, the right end of the left sleeve 1 and the left end of the right sleeve 1 are coaxially fixed with an outer gear ring 5, the lower side of each outer gear ring 5 is engaged with a straight gear 6, the right end of the left straight gear 6 and the left end of the right straight gear 6 are coaxially fixedly connected with a first bevel gear 7, the small ends of the two first bevel gears 7 are opposite, and a second bevel gear 8 engaged with the two first bevel gears 7 is arranged between the two first bevel gears 7; the rotation of the second bevel gear 8 can drive the two sleeves 1 to synchronously rotate reversely through the two first bevel gears 7, the two straight gears 6 and the two external gear rings 5.
The outer end of each rectangular block 3 is provided with a blind hole 9, the threaded rods 2 penetrate through the blind holes 9, and a pressure spring 10 is arranged between the inner end of each group of threaded rods 2 and the bottom of each blind hole 9; the rectangular block 3 can move along the axial direction of the threaded rod 2 so as to solve the problem that the alignment is absolutely accurate when the plurality of threaded rods 2 are adjusted respectively.
In order to prevent the rectangular blocks 3 from falling off the threaded rods 2, each threaded rod 2 is provided with a fixing plate 11 positioned on the outer side of each rectangular block 3, each fixing plate 11 is provided with a through hole 12 parallel to the threaded rod 2, the outer end of each rectangular block 3 is fixed with a bolt 13, the outer end of each bolt 13 penetrates through the through hole 12 and is screwed with a nut 14, and the bolt 13 can slide in the through hole 12; when the device is installed, the rectangular block 3 is sleeved at the end part of the threaded rod 2, the bolt 13 penetrates through the through hole 12, and then the nut 14 is screwed.
The left end and the right end of each rectangular block 3 and each grinding sheet 4 are provided with chamfers, so that the pipeline can conveniently penetrate through the rectangular blocks 3.
A bearing seat 15 is arranged outside the two sleeves 1, and the sleeves 1 are arranged in the bearing seats 15 through bearings 16.
The utility model discloses a second bevel gear 8 is by motor drive, when using, at first adjust each threaded rod 2 and stretch into the length in the sleeve pipe 1, make the distribution circle diameter of a plurality of abrasive discs 4 in each sleeve pipe 1 slightly less than the external diameter of waiting to grind the pipeline, then start motor, motor drive second bevel gear 8 rotates, second bevel gear 8 drives two first bevel gear 7 rotations, the direction of rotation of two first bevel gear 7 is opposite, two first bevel gear 7 drive two sleeve pipes 1 through two straight-toothed gear 6 and two outer ring gears 5 with the same speed contrarotation; at the moment, one end of the pipeline sequentially penetrates through the two sleeves 1, the pipeline sequentially penetrates through the grinding sheets 4 in the two sleeves 1, the grinding sheets 4 on the two sleeves 1 are both contacted with the outer wall of the pipeline and are pressed by the pressure spring 10, and the grinding sheets 4 rotate along with the sleeves 1 to polish and derust the outer wall of the pipeline; and pushing the pipeline to completely penetrate through the two sleeves 1, and finishing the rust removal of the outer wall of the whole pipeline.
Because the rectangular block 3 can move relative to the threaded rod 2, even if the threaded rods 2 cannot completely align when being adjusted, when the pipeline passes through the sleeve 1, the rectangular block 3 compresses the pressure spring 10 to move relative to the threaded rod 2, so that automatic alignment can be realized, and each abrasive disc 4 can effectively contact and press the outer wall of the pipeline.
Two sets of abrasive disc 4 antiport in two sleeve pipes 1 can guarantee on the one hand that the rust cleaning is more comprehensive, and on the other hand, because two sleeve pipes 1 rotate the opposite phase, the torque of two sets of abrasive disc 4 that consequently the pipeline received is approximate balanced, and the pipeline can not violently rotate, is convenient for grip the propulsion, also safer.
When the pipeline with different outer diameters is derusted, the threaded rods 2 are screwed, so that the diameter of the distribution circle of the grinding sheet 4 is matched with the outer diameter of the pipeline.
The above "inner" refers to the direction towards the centre of the sleeve and "outer" refers to the direction away from the centre of the sleeve.
The utility model discloses a set up two sets of circumference equipartitions and reverse rotation's abrasive disc 4, can be quick comprehensive polish the rust cleaning to the pipeline outer wall, improved work efficiency greatly, moreover, through the diameter of adjusting a plurality of abrasive discs 4's distribution circle, can polish to the pipeline of various pipe diameters, strong adaptability.
