DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] A steel rust removal device for construction engineering, such as Figure 1-Figure 5 As shown, it includes a base 1, side panels 2, a rotating shaft 3, a grinding roller 5, a driving assembly, a fixing mechanism and a transmission mechanism. The left and right sides of the top of the base 1 are connected to the side panels 2, the rotating shaft 3 is rotatably connected between the two side panels 2, the rotating shaft 3 is connected to the grinding roller 5, the base 1 is provided with a driving assembly for driving the rotating shaft 3 to rotate, the rotating shaft 3 is provided with a fixing mechanism for fixing the steel pipe 100, and a transmission mechanism is provided between the rotating shaft 3 and the fixing mechanism.

[0029] like Figure 2 As shown, the driving assembly includes a driving motor 41 and a belt transmission group 42. The driving motor 41 is installed on the right side of the base 1, and the belt transmission group 42 is connected between the output shaft of the driving motor 41 and the rotating shaft 3, so that the driving motor 41 can drive the rotating shaft 3 to rotate through the belt transmission group 42.

[0030] like Figure 2-Figure 4As shown, the fixing mechanism includes a rotating disk 61, a guide frame 62, a slider 63, a sliding shaft 64, a contact disk 65, an elastic member 66, a guide block 67 and an extension disk 68. The rotating disk 61 is rotatably connected to the left and right sides of the rotating shaft 3. Three guide frames 62 are evenly spaced along the circumferential direction on the rotating disk 61. The slider 63 is slidably connected in the guide frame 62. The slider 63 is slidably connected to the sliding shaft 64. The ends of the sliding shafts 64 on both sides that are close to each other are rotatably connected to the contact disk 65. An elastic member 66 is connected between the movable shaft 64 and the slider 63. The elastic member 66 is a connecting spring. The ends of the sliding shafts 64 on both sides that are away from each other are connected to extension plates 68. The lower parts of the sides of the two side plates 2 that are close to each other are connected to guide blocks 67. The guide blocks 67 are provided with inclined surfaces. The inclined surfaces of the guide blocks 67 are located at the moving track of the extension plates 68, so that the extension plates 68 will contact with the guide blocks 67 when moving and be squeezed and moved by the guide blocks 67, thereby driving the sliding shafts 64 to slide.

[0031] like Figure 3 and Figure 5 As shown, the transmission mechanism includes a small ring gear 71, a transmission gear 72, a connecting rod 73, a driving gear 74 and a large ring gear 75. The two ends of the rotating shaft 3 are connected to the small ring gear 71, and the upper parts of the two side plates 2 are rotatably connected to the connecting rods 73. The ends of the two connecting rods 73 that are away from each other are connected to the transmission gear 72, and the transmission gear 72 is meshed with the small ring gear 71. The ends of the two connecting rods 73 that are close to each other are connected to the driving gear 74. The two rotating disks 61 are connected to the large ring gear 75, and the driving gear 74 is meshed with the large ring gear 75, so that the rotating shaft 3 can drive the rotating disk 61 to rotate through the transmission of the small ring gear 71, the transmission gear 72, the connecting rod 73, the driving gear 74 and the large ring gear 75 when rotating.

[0032] When it is necessary to remove rust from the steel pipe 100, the rust removal device can be used. When in use, first control the drive motor 41 to operate to drive the rotating shaft 3 and the grinding roller 5 to rotate through the belt transmission group 42. When the rotating shaft 3 rotates, it will drive the rotating disk 61 to rotate through the small ring gear 71, the transmission gear 72, the connecting rod 73, the driving gear 74 and the large ring gear 75. When the rotating disk 61 rotates, it will drive the guide frame 62 to rotate. When the guide frame 62 rotates to its end facing downward, the slider 63 will slide down along the guide frame 62. At this time, the guide frame 62 continues to rotate and drives the extension disk 68 to contact the guide block 67, so that the extension disk 68 moves toward the side plate 2 through the inclined surface on the guide block 67. The elastic member 66 is stretched, and the extension disk 68 can drive the contact disk 65 to move through the sliding shaft 64 when moving, so that the two contact disks 65 are opened to each other. At this time, if the two contact disks 65 are connected There was originally a steel pipe 100 in the space, and the steel pipe 100 will fall on the base 1, and then the steel pipe 100 can be placed between the two contact plates 65. After placement, the guide frame 62 continues to rotate to drive the extension plate 68 to disengage from the guide block 67. At this time, under the action of the elastic member 66, the sliding shaft 64 is reset to drive the contact plate 65 to reset and resist the steel pipe 100. Then the guide frame 62 continues to rotate, which will make the end of the guide frame 62 face upward. At this time, the slider 63 slides down to drive the steel pipe 100 to move, so that the steel pipe 100 contacts the grinding roller 5, thereby grinding the steel pipe 100 through the grinding roller 5. This is repeated, and the steel pipe 100 can be added and ground. In the process of adding the steel pipe 100 and unloading the steel pipe 100, there is no need to shut down the device to process the steel pipe 100, which is more convenient to operate and effectively improves the rust removal efficiency.

[0033] like Figure 6 As shown, it also includes a power transmission mechanism, which includes a connecting gear 81, a cylindrical gear 82 and an outer ring gear 83. The left and right sides of the rotating shaft 3 are connected with connecting gears 81, and the sides of the two rotating disks 61 close to each other are connected with three cylindrical gears 82 that rotate evenly at intervals along the circumferential direction. The three cylindrical gears 82 are all meshed with the connecting gear 81, and each contact disk 65 is connected with an outer ring gear 83. The movement of the contact disk 65 can drive the outer ring gear 83 to mesh with the cylindrical gear 82.

[0034] When the end of the guide frame 62 rotates upward, the slider 63 slides downward along the guide frame 62. At this time, the slider 63 can drive the sliding shaft 64 and the contact plate 65 to move together. After the contact plate 65 moves, it can drive the outer ring gear 83 to engage with the cylindrical gear 82. When the rotating shaft 3 rotates, it can drive the outer ring gear 83 to rotate through the connecting gear 81 and the cylindrical gear 82. The rotation of the outer ring gear 83 can drive the contact plate 65 to rotate, thereby driving the steel pipe 100 to rotate. The rotation of the steel pipe 100 cooperates with the grinding roller 5, so that the steel pipe 100 can be polished and rust-removed.

[0035] like Figure 7 and Figure 8 As shown, it also includes a feeding mechanism, which includes a side frame 91, a belt conveyor group 92, a connecting shaft 93, a reduction motor 94 and a material shifting rod 95. The left and right sides of the base 1 are connected to the side frames 91, and the connecting shafts 93 are rotatably connected between the lower front parts and the upper rear parts of the two side frames 91. The belt conveyor groups 92 are wound around the left and right sides and the middle parts of the two connecting shafts 93. The belt conveyor groups 92 are evenly spaced and connected to the material shifting rods 95. When placing the steel pipes 100, the steel pipes 100 can be placed on the three belt conveyor groups 92, and the steel pipes 100 are separated by the material shifting rods 95. When the belt conveyor group 92 rotates, the steel pipes 100 can be transported by the material shifting rods 95. A reduction motor 94 is installed on the right side of the base 1, and the output shaft of the reduction motor 94 is connected to the connecting shaft 93 on the front side.

[0036] When adding steel pipes 100, the steel pipes 100 can be placed between the three belt conveyor groups 92. When the steel pipes 100 need to be transported between the two contact plates 65, the reduction motor 94 can be used to drive the connecting shaft 93 to rotate. When the connecting shaft 93 rotates, it can drive the belt conveyor group 92 to rotate. When the belt conveyor group 92 rotates, it can drive the material moving rod 95 to rotate. When the material moving rod 95 rotates, it can move the steel pipe 100 between the two contact plates 65, so as to facilitate the addition of the steel pipes 100. During manual operation, it is only necessary to place multiple steel pipes 100 on the belt conveyor group 92 at one time, which is more convenient to operate.

[0037] like Fig. 9 As shown, a protective cover 10 is also included. The protective cover 10 is connected between the upper parts of the two side panels 2. The protective cover 10 can shield the grinding debris during the grinding process to prevent the debris from splashing.

[0038] like Fig.10 As shown, it also includes a clamping frame 11 and an elastic member 12. A plurality of clamping frames 11 are evenly spaced and slidably connected to the top of the protective cover 10. An elastic member 12 is connected between the clamping frame 11 and the protective cover 10. The elastic member 12 is a tension spring. When the contact plate 65 presses against the steel pipe 100 to transmit the steel pipe 100, the steel pipe 100 will contact the bottom of the clamping frame 11 and squeeze the clamping frame 11 to move upward, so that the elastic member 12 is stretched. At this time, the elastic member 12 can apply downward pressure to the clamping frame 11, so that the clamping frame 11 presses the steel pipe 100 and makes the steel pipe 100 close to the grinding roller 5, so as to facilitate the grinding of the grinding roller 5.

[0039] like Fig.11As shown, a waste box 13 is also included. The lower part of the base 1 is slidably connected to the waste box 13. The top of the base 1 is evenly spaced with a plurality of drop holes. When debris falls on the base 1, the debris will fall into the waste box 13 through the drop holes. The waste box 13 is used to collect and process the debris generated during the grinding process.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
