Description

Technical Field

[0001] The utility model relates to the technical field of grinding, in particular to a pipeline outer wall grinding device. Background Art

[0002] Pipes are generally factory-fixed in length. In actual use, the lengths of pipes vary, so cutting, splicing and welding are more common. After the pipes are spliced ​​and welded into one, the external welds of the pipes need to be polished. In actual use, manual polishing is used. The original polishing method is time-consuming and labor-intensive, and the polishing efficiency is low. There is also a separate polishing device, which places the pipe on its operating table and then rotates to polish the annular weld, or drives the pipe to rotate and then polishes the annular weld on the outer wall. This polishing method also requires the pipe to be moved up and down, which poses a safety risk. At the same time, the energy consumption of driving the pipe to rotate is high. For this reason, a pipe outer wall polishing device is designed that can be directly tied to the pipe and can rotate circumferentially along the outer wall of the pipe. It can be polished as it rotates, which improves the polishing efficiency while eliminating the safety risk of moving the pipe for pipe polishing, and reduces energy consumption.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-5 A pipeline outer wall grinding device includes a bandage 1, a plurality of sliding sleeves 2 that can be locked on the bandage 1 are provided on the guide sliding cooperation on the bandage 1, a grinding mechanism is provided on the sliding sleeve 2, and a moving mechanism is provided around the grinding mechanism, and also includes a grinding depth adjustment mechanism for adjusting the distance between the grinding mechanism and the sliding sleeve 2. Furthermore, the bandage 1 can be set as a belt structure and can be customized accordingly according to the outer diameter of the pipeline.

[0024] Specifically, the grinding mechanism includes a U-shaped frame 7 which is slidably matched with the guide sleeve 2, and a grinding roller 8 is rotatably connected to the U-shaped frame 7. The U-shaped frame 7 also includes a grinding drive component which drives the grinding roller 8 to rotate. When the grinding drive component is started, the grinding roller 8 is driven to rotate, and the raised portion of the weld on the outer wall of the pipe can be ground by the rotating grinding roller 8.

[0025] Specifically, the grinding drive component includes a grinding motor 9 fixedly mounted on the U-shaped frame 7. The output shaft of the grinding motor 9 and one end of the grinding roller 8 are fixedly connected with a bevel gear 10, and the two bevel gears 10 are meshed. When the grinding motor 9 is started, the output shaft of the grinding motor 9 rotates, and the meshing of the two bevel gears 10 facilitates the rotation of the grinding roller 8.

[0026] Specifically, a guide clamping rod 12 that is in sliding cooperation with the guide limiting sliding of the sliding sleeve 2 is fixedly connected to the side of the U-shaped frame 7 away from the grinding roller 8. A plurality of positioning holes 13 that are compatible with the guide clamping rod 12 are spaced apart along the length direction on the binding belt 1. A compression spring 11 is arranged between the U-shaped frame 7 and the sliding sleeve 2. The guide clamping rod 12 is used to guide and limit the U-shaped frame 7 to prevent the U-shaped frame 7 from being separated from the connection with the sliding sleeve 2. The setting of the compression spring 11 makes it easy to separate the guide clamping rod 12 from the positioning hole 13 in a natural state. When the binding belt 1 is tied tightly to the outer wall of the pipe, the grinding roller 8 is first pushed toward the sliding sleeve 2, so that the compression spring 11 is further compressed, and the guide clamping rod 12 passes through the positioning hole 13. Furthermore, the two ends of the compression spring 11 are respectively fixedly connected to the U-shaped frame 7 and the sliding sleeve 2.

[0027] Specifically, the grinding depth adjustment mechanism includes a limit frame 14 arranged on the side of the sliding sleeve 2 away from the U-shaped frame 7, and the side of the guide clamping rod 12 away from the U-shaped frame 7 can contact the side of the limit frame 14 close to the sliding sleeve 2. The sliding sleeve 2 is fixedly connected with a guide rod 17 parallel to the guide clamping rod 12, and the limit frame 14 slides with the guide rod 17. A screw 15 is threadedly connected to the limit frame 14, one end of the screw 15 is rotatably connected to the sliding sleeve 2, and the other end of the screw 15 is fixedly connected with a dovetail button 16. By rotating the dovetail button 16 clockwise or counterclockwise, it is easy to drive the screw 15 to rotate clockwise or counterclockwise, and then under the guiding action of the guide rod 17, the limit frame 14 can be moved to the side close to or away from the sliding sleeve 2, and then the guide clamping rod 12 that penetrates to the other side of the sliding sleeve 2 can be contracted and adjusted under the cooperation of the compression spring 11, so that the indirection between the grinding mechanism and the sliding sleeve 2 can be adjusted, and then the grinding depth can be adjusted.

[0028] Specifically, the moving mechanism includes a moving roller 3 rotatably connected to the sleeve 2, and also includes a moving driving member that drives the moving roller 3 to rotate. Starting the moving driving member is convenient to drive the moving roller 3 to rotate. Through the rotation of the moving roller 3, the sleeve 2 can be driven to rotate circumferentially around the outer wall of the pipeline. The moving driving member includes a moving motor 5 fixedly mounted on the sleeve 2. The moving rollers 3 located on both sides of the grinding mechanism are fixedly connected through a rotating shaft 4. The moving motor 5 and the rotating shaft 4 are connected through a synchronous belt 6. Starting the moving motor 5 is convenient to drive the rotating shaft 4 to rotate through the transmission cooperation of the synchronous belt 6, and then drive the two moving rollers 3 on the same side to rotate.

[0029] When in use, the plurality of guide sleeves 2 sliding on the binding band 1 can be ring-bound on the pipe through the binding band 1, and the grinding mechanism is bound in the direction of the pipe, and the plurality of sleeves 2 are dispersed, so that the plurality of sleeves 2 are circumferentially arranged on the pipe, and the binding band 1 is separated from the contact with the pipe, and at the same time, the mobile mechanisms on all sides ride on both sides of the weld of the outer wall of the pipe and contact the pipe, and the grinding mechanism is started to grind the weld of the outer wall of the pipe in the middle position, and the moving mechanism drives the whole to move circumferentially around the outer wall of the pipe, thereby driving the grinding mechanism to grind the weld of the outer wall of the pipe, and then the distance between the grinding mechanism and the weld of the outer wall of the pipe can be adjusted by the grinding depth adjustment mechanism, thereby adjusting the grinding depth, so that the raised part of the weld can be completely ground flat in multiple times according to the raised height of the weld.
