Description

Technical Field

[0001] This utility model belongs to the field of rust removal machines, and in particular relates to a rust removal and grinding machine suitable for long pipes of different diameters. Background Technology

[0002] Before assembling pipe fittings into membrane structure frames, columns, etc., the pipe fittings need to be derusted and ground to facilitate subsequent processing (welding, painting, etc.). Of course, shot blasting is also available now. After metal shot blasting, tiny pits will appear on the surface of the parts. For projects such as landscape engineering and fitness equipment, the surface smoothness of the parts is required to be high. Shot blasting cannot meet the smoothness requirements. Generally, the pipe fittings used as columns, frames, etc. have various diameter specifications, ranging from 4.8-50cm, and lengths from 1 meter to 12 meters. These factors also make the pipe fittings relatively heavy. Ordinary rust removal and grinding machines cannot support long pipes or are not suitable for different pipe diameters. Utility Model Content

[0003] (1) Technical problem to be solved: Provide a rust removal and grinding machine suitable for long pipes of different diameters.

[0004] (2) The technical solution adopted by this utility model is as follows:

[0005] A rust removal and grinding machine suitable for long pipes of different diameters includes a frame, a power shaft mounted on the frame, multiple shaft stabilizing wheel sets between the bottom of the power shaft and the frame, both ends of the power shaft connected to the frame via bearing seats, a drive device connected to the power shaft, a movable base mounted on the frame, the movable base slidably connected to the frame, an adjusting assembly connected to the movable base, multiple guide wheels mounted on the movable base, the guide wheels arranged along the axial direction of the power shaft, the axial direction of the guide wheels forming an angle with the axial direction of the power shaft, the guide wheels connected to a wheel frame via axles, a connecting rod mounted at the bottom of the wheel frame, one end of the connecting rod rotatably connected to the movable base via a first positioning shaft, the other end of the connecting rod rotatably connected to a linkage base via a second positioning shaft, a positioning assembly connected to the linkage base, and a grinding device mounted on the frame.

[0006] A further technical solution is that the grinding device includes a base, on which a motor and a grinding wheel are mounted. The grinding wheel and the base are connected by a connecting shaft, which is coaxially fixed with the grinding wheel and rotatably connected to the base. The output shaft of the motor is connected to the connecting shaft through a transmission mechanism. The grinding device includes two parts.

[0007] A further technical solution is that the base is slidably connected to the frame, a first adjusting screw is rotatably connected to the frame, a first screw sleeve is provided on the base, and the first adjusting screw is connected to the first screw sleeve.

[0008] A further technical solution is that the adjusting assembly includes a second adjusting screw and a third adjusting screw, a second screw sleeve is fixedly provided on one side of the frame, the second adjusting screw is threadedly connected to the second screw sleeve, and the end of the second adjusting screw contacts the side of the movable base. A third screw sleeve is fixedly provided on the other side of the frame, the third adjusting screw is threadedly connected to the third screw sleeve, and the end of the third adjusting screw contacts the other side of the movable base.

[0009] A further technical solution is that the positioning component includes a fourth adjusting screw and a fifth adjusting screw, a fourth screw sleeve is fixedly installed on one side of the movable base, the fourth adjusting screw and the fourth screw sleeve are threadedly connected, the end of the fourth adjusting screw contacts the side of the linkage base, a fifth screw sleeve is fixedly installed on the other side of the movable base, the fifth adjusting screw and the fifth screw sleeve are threadedly connected, and the end of the fifth adjusting screw contacts the other side of the linkage base.

[0010] (3) Due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0011] By setting multiple shaft stabilizing wheel sets between the bottom of the power shaft and the frame, and connecting both ends of the power shaft to the frame through bearing seats, the power shaft can be made to be relatively long without bending or deformation in the middle, and the support capacity of the power shaft for the pipe fittings is also guaranteed.

[0012] A movable base is installed on the frame and is slidably connected to the frame. The movable base is connected to an adjustment assembly. Multiple guide wheels are installed on the movable base and are arranged along the axial direction of the power shaft. The axial direction of the guide wheels is set at an angle to the axial direction of the power shaft. In use, the pipe can be placed between the guide wheels and the power shaft. The power shaft is driven to rotate by the drive device, which in turn causes the pipe and guide wheels to rotate. Because the axial direction of the guide wheels is set at an angle to the axial direction of the power shaft, the pipe moves while rotating. The distance between the movable base and the power shaft can be adjusted by using the adjustment assembly, thereby adjusting the distance between the power shaft and the guide wheels. This method is suitable for pipes with different diameters.

[0013] The guide wheel is connected to the wheel frame via an axle. A connecting rod is installed at the bottom of the wheel frame. Since one end of the connecting rod is rotatably connected to the movable base via a first positioning shaft, and the other end of the connecting rod is rotatably connected to the linkage base via a second positioning shaft, moving the linkage base can change the angle of the wheel frame, thereby changing the angle between the axial direction of the guide wheel and the axial direction of the power shaft, thus controlling the moving speed of the pipe fitting. For pipe fittings with larger diameters, the moving speed can be slowed down to ensure the effect of rust removal and grinding. For pipe fittings with smaller diameters, the moving speed can be increased to ensure the speed of rust removal and grinding. The linkage base can be moved and positioned using the positioning component. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] like Figures 1-16 As shown. A rust removal and grinding machine suitable for long pipes of different diameters includes a frame 1, a power shaft 2 mounted on the frame 1, multiple shaft stabilizing wheel sets 3 between the bottom of the power shaft 2 and the frame 1, both ends of the power shaft 2 connected to the frame 1 via bearing seats 4, the power shaft 2 connected to a drive device, a movable base 5 mounted on the frame 1, the movable base 5 slidably connected to the frame 1, the movable base 5 connected to an adjustment component, multiple guide wheels 6 mounted on the movable base 5, the multiple guide wheels 6 arranged along the axial direction of the power shaft 2, the axial direction of the guide wheels 6 forming an angle with the axial direction of the power shaft 2, the guide wheels 6 connected to a wheel frame 7 via axles, a connecting rod 8 mounted at the bottom of the wheel frame 7, one end of the connecting rod 8 rotatably connected to the movable base 5 via a first positioning shaft 9, the other end of the connecting rod 8 rotatably connected to a linkage base 15 via a second positioning shaft 10, the linkage base 15 connected to a positioning component, and a grinding device mounted on the frame 1.

[0032] In use, this utility model applies to round pipes. The frames and columns of the membrane structure are basically round pipes (it can also be used for round pipes of different lengths, square pipes of different diameters and lengths, and long steel pipes of other shapes). The pipes can be manually lifted between the power shaft 2 and the guide wheel 6 or hoisted between the power shaft 2 and the guide wheel 6 by a crane. The drive device is started, which drives the power shaft 2 to rotate. The power shaft 2 drives the pipe to rotate. When the pipe rotates, it moves towards the grinding device under the action of the guide wheel 6. The grinding device includes a base 11. A motor 12 and a grinding wheel 13 are mounted on the base 11. The grinding wheel 13 is connected to the base 11 via a connecting shaft 14. The connecting shaft 14 and the grinding wheel 13 are coaxially fixed and rotatably connected to the base 11. The output shaft of the motor 12 is connected to the connecting shaft 14 via a transmission mechanism. The grinding device includes two parts. When the motor 12 in the two grinding devices is started, the motor 12 drives the connecting shaft 14 and the grinding wheel 13 to rotate via the transmission mechanism (chain drive or belt drive). The grinding wheel 13 removes rust and grinds the pipe until the grinding is completed.

[0033] The driving device is a geared motor 12, which is fixed to the frame 1. The output shaft of the geared motor 12 is connected to the power shaft 2 through a transmission mechanism (chain drive or belt drive), thereby driving the power shaft 2 to rotate. The geared motor 12 can generate a torque at the output end that is much greater than that of a regular motor 12, so it can be used in this utility model to drive the power shaft 2 to rotate in high-load or high-torque applications.

[0034] The rotation direction of the drive shaft 2 should cause the pipe to move upward. In the figure, the drive shaft 2 rotates counterclockwise and the pipe rotates clockwise. The orientation of the guide wheel 6 determines the direction of the pipe's movement. The pipe's movement speed varies depending on the angle between the axis of the guide wheel 6 and the axis of the drive shaft 2 (provided that the speed of the drive shaft 2 driven by the reducer remains constant). The larger the angle, the faster the speed.

[0035] The structure in which the movable base 5 is slidably connected to the frame 1 is that the frame 1 is provided with two first sliding grooves 26, and the bottom of the movable base 5 is provided with a first limiting block 27 that matches the sliding groove. The first limiting block 27 is located inside the first sliding groove 26. Alternatively, the structure in which the movable base 5 is slidably connected to the frame 1 can be that the frame 1 is provided with two first guide rails, and a first slider is provided on the first guide rail. The first slider is fixed to the movable base 5 by bolts.

[0036] The shaft stabilizing wheel assembly 3 includes two stabilizing wheels arranged opposite each other. The stabilizing wheels are connected to the frame 1 via wheel brackets, which are fixed to the frame 1. The stabilizing wheels are rotatably connected to the wheel brackets. The two stabilizing wheels of the shaft stabilizing wheel assembly 3 support the bottom of the power shaft 2. Multiple shaft stabilizing wheel assemblies 3 can accommodate the length of the power shaft 2; the specific number is determined based on the length of the power shaft 2.

[0037] The linkage base 15 is not connected to the movable base 5. The linkage base 15 is simply placed on the movable base 5 and can move on the movable base 5.

[0038] The grinding wheel 13 is the existing wire mesh grinding wheel 13 (also known as wire wheel, rust removal grinding wheel 13).

[0039] The base 11 is slidably connected to the frame 1. A first adjusting screw 16 is rotatably connected to the frame 1. A first threaded sleeve 17 is fixedly installed on the base 11. The first adjusting screw 16 is connected to the first threaded sleeve 17. The sliding connection structure between the base 11 and the frame 1 is that the frame 1 is provided with two second sliding grooves 30. The bottom of the base 11 is provided with a second limiting block 31 that matches the second sliding groove 30. The second limiting block 31 is located inside the second sliding groove 30. Alternatively, the sliding connection structure between the base 11 and the frame 1 can be that a second guide rail is provided on the frame 1, and a second slider is provided on the second guide rail. The second slider is fixed to the base 11 by bolts. A handwheel is provided at the end of the first adjusting screw 16. Rotating the first adjusting screw 16 can drive the base 11 to move, thereby controlling the distance between the grinding device and the pipe fitting, and adapting to pipe fittings of different diameters.

[0040] The distance adjustment assembly includes a second adjusting screw 18 and a third adjusting screw 19. A second screw sleeve 20 is fixedly installed on one side of the frame 1, and the second adjusting screw 18 is threadedly connected to the second screw sleeve 20. The end of the second adjusting screw 18 contacts the side of the movable base 5. A third screw sleeve 21 is fixedly installed on the other side of the frame 1, and the third adjusting screw 19 is threadedly connected to the third screw sleeve 21. The end of the third adjusting screw 19 contacts the other side of the movable base 5. Both the second adjusting screw 18 and the third adjusting screw 19 are equipped with handwheels. Rotating the second adjusting screw 18 can push the movable base 5 closer to the power shaft 2 (first loosen the third adjusting screw 19 to move it away from the movable base 5, and then tighten the third adjusting screw 19 after the second adjusting screw 18 has been adjusted). Rotating the third adjusting screw 19 can push the movable base 5 away from the power shaft 2 (first loosen the second adjusting screw 18 to move it away from the movable base 5, and then tighten the second adjusting screw 18 after the third adjusting screw 19 has been adjusted), thereby realizing the distance adjustment between the guide wheel 6 and the power shaft 2.

[0041] The positioning assembly includes a fourth adjusting screw 22 and a fifth adjusting screw 23. A fourth screw sleeve 24 is fixedly installed on one side of the movable base 5. The fourth adjusting screw 22 and the fourth screw sleeve 24 are threadedly connected. The end of the fourth adjusting screw 22 contacts the side of the linkage base 15. A fifth screw sleeve 25 is fixedly installed on the other side of the movable base 5. The fifth adjusting screw 23 and the fifth screw sleeve 25 are threadedly connected. The end of the fifth adjusting screw 23 contacts the other side of the linkage base 15. The fourth adjusting screw 22 and the fifth adjusting screw 23 are respectively set at both ends of the movable base 5. Vertical plates are set on both sides of the linkage base 15. Handwheels are set on both the fourth adjusting screw 22 and the fifth adjusting screw 23. When the fourth adjusting screw 22 and the fifth adjusting screw 23 simultaneously press against the vertical plates on both sides of the linkage base 15, the position of the linkage base 15 can be locked. Loosening the fourth adjusting screw 22 and rotating the fifth adjusting screw 23 can push the linkage base 15 towards the fourth adjusting screw 22. Loosening the fifth adjusting screw 23 and rotating the fourth adjusting screw 22 can push the linkage base 15 towards the fifth adjusting screw 23, thus enabling the movable and positioned linkage base 15. Moving the linkage base 15 changes the angle of the wheel frame 7, thereby changing the angle between the axial direction of the wheel 6 and the axial direction of the power shaft 2, and thus controlling the moving speed of the pipe fitting.

[0042] In addition, compared with shot blasting, grinding for rust removal reduces energy consumption, is simpler to operate, and requires less space. It has wide applications: it is highly valuable for secondary rust removal in remote areas and for steel markets, compensating for the lack of mobility in shot blasting equipment. It is environmentally friendly and energy-saving: it does not produce harmful waste liquids or gases during operation, making it more environmentally friendly. At the same time, its high efficiency also reduces energy consumption and carbon emissions. It is also quieter; compared with shot blasting equipment, this rust removal and grinding machine operates at below 60 decibels, a reduction of 30-40 decibels.

[0043] The above are merely preferred embodiments of this utility model.
