Description

Technical Field

[0001] The utility model relates to the technical field of spiral steel pipes, in particular to a spiral steel pipe weld grinding device which is convenient for slag removal. Background Art

[0002] For steel pipes with smaller diameters, they can be formed in one piece, but for steel pipes with larger diameters, it is not easy to form in one piece. For this reason, a spiral steel pipe has been derived. The spiral steel pipe is made of strip steel coils as raw materials, extruded at room temperature, and welded by automatic double-wire double-sided submerged arc welding process. The spiral weld needs to be ground. After searching, the patent with publication number CN115533703A discloses a spiral steel pipe weld grinding and polishing machine. When using it, the spiral steel pipe needs to be pushed horizontally from one side into the conveying component and extended into the rotating disk. , and grinding belts are set on both sides of the rotating disk to grind both sides of the bolt steel pipe. At the same time, the spiral steel pipe needs to be pushed horizontally. When the grinding is about to be completed, the spiral steel pipe is easy to tilt in the rotating disk, which can easily cause the grinding to be suspended. Through this processing method, the front and rear space requirements are relatively large, that is, the width of horizontal pushing and pushing out needs to be guaranteed, and the applicable site has requirements. For this reason, a spiral steel pipe weld grinding device is designed that can grind the spiral steel pipe without a large operating space, and at the same time it is convenient to collect the grinding slag, which is convenient for slag removal.

Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0022] Example:

[0024] Specifically, the grinding structure includes a horizontal moving platform 5 that can move horizontally under the two hosting rollers 2, and also includes a horizontal moving mechanism that drives the horizontal moving platform 5 to move horizontally. The grinding mechanism and the debris collection mechanism are both arranged on the horizontal moving platform 5 and are arranged on the horizontal moving platform 5 through a lifting mechanism. The horizontal moving mechanism facilitates the horizontal moving platform 5 to move horizontally under the two hosting rollers 2, thereby driving the grinding mechanism and the debris collection mechanism to move horizontally. The lifting mechanism facilitates the grinding mechanism and the debris collection mechanism to be raised and lowered.

[0025] Specifically, the debris collecting mechanism includes a debris collecting hopper 7, the grinding mechanism includes a grinding roller 4 and a grinding motor 8 that drives the grinding roller 4 to rotate, the grinding roller 4 is rotatably connected to the top of the debris collecting hopper 7, and the grinding motor 8 is fixedly installed on the debris collecting hopper 7. The top of the lifting mechanism is connected to the bottom of the debris collecting hopper 7. By starting the grinding motor 8, it is convenient to drive the grinding roller 4 to rotate, thereby driving the grinding roller 4 to grind the spiral weld, and the debris collected by the debris collecting hopper 7 is convenient to receive the fallen debris. Further, the lifting mechanism includes a lower lifting drive cylinder 9 fixedly installed on the bottom of the horizontal moving platform 5, and the output shaft of the lower lifting drive cylinder 9 is fixedly installed with a support frame 6 that is vertically guided and slidably matched with the horizontal moving platform 5. The top of the support frame 6 is fixedly connected to the bottom of the debris collecting hopper 7, and the lower lifting drive cylinder 9 is used to facilitate the lifting and lowering of the debris collecting hopper 7 and the grinding roller 4 through the support frame 6.

[0026] Specifically, the horizontal moving mechanism includes a one-way screw 10 that is horizontally rotated and connected to the hosting frame 1. The horizontal moving platform 5 is threadedly connected to the one-way screw 10. A guide cross bar 11 that is parallel to the one-way screw 10 is provided on one side of the one-way screw 10.

It also includes a moving motor 12 that drives the one-way screw 10 to rotate. When the moving motor 12 is started, the output shaft of the one-way screw 10 rotates clockwise or counterclockwise, which facilitates the one-way screw 10 to rotate clockwise or counterclockwise, and then drives the horizontal moving platform 5 to move horizontally to the left or right under the guide sliding cooperation of the guide cross bar 11.

[0027] Specifically, a vertical frame 13 is fixedly connected to one side of the middle of the hosting frame 1, and a lifting plate 15 is vertically slidably fitted on the vertical frame 13 through an upper lifting drive cylinder 14. The rotating roller 3 is rotatably connected to the bottom of the lifting plate 15, and a rotating drive component for driving the rotating roller 3 to rotate is also provided on the lifting plate 15. Through the upper lifting drive cylinder 14, it is convenient to drive the lifting plate 15 and the rotating roller 3 to move up and down as a whole, and start the rotating drive component to drive the rotating roller 3 to rotate.

[0028] Specifically, the rotating rollers 3 are provided in two groups and are respectively arranged on both sides of the bottom of the lifting plate 15. The bottom of the lifting plate 15 is rotatably connected to the rotating shaft 16. The rotating driving member is used to drive the rotating shaft 16.

When the spacing adjustment member is started, the output shaft of the spacing adjustment member rotates clockwise or counterclockwise, synchronously driving the bidirectional screw 18 to rotate clockwise or counterclockwise, thereby driving the two guide frames 19 to move toward the middle or to both sides, and then driving the two rotating rollers 3 to move toward the middle or to both sides on the rotating shaft 16, thereby facilitating the passage of spiral welds suitable for different pitches between the two rotating rollers 3.

[0030] When in use, a crane can be used to directly place the spiral steel pipe between the two hosting rollers 2, and then the rotating roller 3 can be lowered to be close to the spiral steel pipe, and then the rotating roller 3 can be rotated to drive the spiral steel pipe to rotate, and then the grinding structure can be moved to the lower side of one end of the spiral steel pipe, and the grinding mechanism can be moved up to grind the spiral weld through the grinding mechanism. While grinding, the grinding mechanism can be driven to move to the other side at a uniform speed to ensure that the grinding mechanism always grinds the spiral weld. After grinding is completed, the rotating roller 3 can be moved up, and then the spiral steel pipe can be lifted down, and then the above operation can be repeated.
