[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.
[0029] Example:
[0030] refer to Figures 1 to 4 This embodiment provides a wall grinding device that can be used for building wall repair work, including: a grinding mechanism, a lifting mechanism, a swing mechanism, a height adjustment mechanism, and a support mechanism.
[0031] The sanding mechanism is used to sand the wall surface. In one specific embodiment, the sanding mechanism includes a sanding disc 19, which can sand the wall surface while rotating.
[0032] The grinding mechanism is mounted on the lifting mechanism, which is used to make the grinding mechanism reciprocate along the lifting direction when grinding the wall.
[0033] The lifting mechanism is mounted on the swing mechanism, which is used to make the lifting mechanism rotate.
[0034] The swing mechanism is mounted on the height adjustment mechanism, which is used to adjust the vertical height of the swing mechanism.
[0035] The height adjustment mechanism is located on the support mechanism.
[0036] By cooperating with the swing mechanism and the height adjustment mechanism, the grinding disc 19 can rotate and rise, thereby enabling free adjustment of the small-area grinding position on the wall. Combined with the lifting mechanism, the rotation diameter of the grinding disc 19 can be freely adjusted, thus enabling large-area grinding of the wall, replacing manual grinding, effectively reducing the labor intensity of workers, and the rotation radius during grinding can be freely adjusted, so that the grinding disc 19 rotates in a vortex shape, which can improve the grinding speed and improve work efficiency.
[0037] In a preferred embodiment, the grinding mechanism includes a third motor 16, a mounting shaft 17 fixed to the output end of the third motor 16, a mounting bracket 18 fixed to the other end of the mounting shaft 17, and a grinding disc 19 fixed to the mounting bracket 18. A bearing 15 is provided on the lifting mechanism. The bearing 15 is hollow cylindrical and is sleeved on the surface of the mounting shaft 17. The third motor 16 is located at the end of the bearing 15 away from the mounting bracket 18 through a fixed mounting seat (not shown). The mounting shaft 17 rotatably passes through the bearing 15. The bearing 15 and the mounting shaft 17 can rotate relative to each other through a bearing. In use, the grinding surface of the grinding disc 19 is in close contact with the wall surface. The third motor 16 works and drives the grinding disc 19 to rotate through the mounting shaft 17 to grind the wall surface.
[0038] In a preferred embodiment, the support mechanism includes a base 1 and two parallel first fixing rods 2 fixed to the base 1 at a distance from each other. A first fixing seat 3 and a second fixing seat 4 are fixedly mounted on the two first fixing rods 2. The first fixing seat 3 is located between the two ends of the first fixing rod 2, for example, near the midpoint of the length direction of the first fixing rod 2. The second fixing seat 4 is located at or near the top of the first fixing rod 2. The support mechanism can raise the height adjustment mechanism, thereby providing space for the lifting mechanism and the rotation of the grinding disc 19. When the grinding disc 19 rotates to the lowest point, it will not touch the ground or the collection hopper 21 on the base 1.
[0039] In a preferred embodiment, the height adjustment mechanism includes a first sliding lifting seat 5 slidably sleeved on the surfaces of the two first fixed rods 2, and a lifting drive assembly for driving the first sliding lifting seat 5 to slide and rise. The lifting drive assembly preferably includes a first motor 6 fixed on the first fixed seat 3, a screw 7 fixed to the output end of the first motor 6, and a threaded cylinder 8 fixed inside the first sliding lifting seat 5. The threaded cylinder 8 is sleeved on the surface of the screw 7, and the two are threadedly connected. The end of the screw 7 away from the first motor 6 is rotatably connected to the second fixed seat 4, and the bottom surface of the screw 7 and the second fixed seat 4 are rotatably connected via bearings. Next, the two first fixed rods 2 play a role in positioning and guiding the first sliding lifting seat 5, preventing the position of the first sliding lifting seat 5 from shifting during the up and down movement, so that the grinding disc 19 can always be in close contact with the wall. The first motor 6 drives the screw 7 to rotate. The screw 7 converts the rotational motion of the screw 7 into the linear motion of the threaded cylinder 8 through the threaded connection with the threaded cylinder 8. The threaded cylinder 8 drives the first sliding lifting seat 5 to rise and fall, thereby achieving the purpose of adjusting the grinding height. Under the guidance of the two first fixed rods 2, the first sliding lifting seat 5 slides in a preset direction, which will not cause the grinding disc 19 to deviate from the wall.
[0040] In a preferred embodiment, the swing mechanism includes a second motor 9 fixedly mounted on the first sliding lifting seat 5, a rotating rod 10 fixed to the output end of the second motor 9, and a connecting shaft 11 fixed to the other end of the rotating rod 10. The output end of the second motor 9 passes through the first sliding lifting seat 5 and achieves relative rotation with the first sliding lifting seat 5 through a sleeve. The second motor 9 is fixed on the vertical plate of the first sliding lifting seat 5, which has an "L" shaped cross-section, and the output shaft faces the wall to be polished. When the second motor 9 is working, it drives the rotating mounting seat 12 to rotate through the rotating rod 10 and the connecting shaft 11, thereby driving the lifting mechanism to rotate.
[0041] In a preferred embodiment, the output end of the second motor 9 and the connecting shaft 11 are perpendicular to both ends of the rotating rod 10 and are located on both sides of the rotating rod 10. The output shaft of the second motor 9, the rotating rod 10 and the connecting shaft 11 are arranged in a "Z" shape with an included angle of less than 90 degrees, thereby driving the lifting mechanism to rotate around the axis of the output shaft of the second motor 9.
[0042] In a preferred embodiment, the lifting mechanism includes a rotating mounting base 12 fixed to the other end of the connecting shaft 11, an electrically controlled telescopic air rod 24 fixed to the rotating mounting base 12, two parallel second fixed rods 13 spaced apart, a second sliding lifting seat 14 slidably sleeved on the surface of the second fixed rods 13, and a bearing bush 15 fixed on the second sliding lifting seat 14. The output end of the electrically controlled telescopic air rod 24 is fixedly connected to the second sliding lifting seat 14. The two second fixed rods 13 can limit and guide the second sliding lifting seat 14, preventing the second sliding lifting seat 14 from deviating during reciprocating motion. When the electrically controlled telescopic air rod 24 is working, it can drive the second sliding lifting seat 14 to reciprocate along the axial direction of the second fixed rods 13, thereby driving the grinding mechanism to reciprocate along the lifting direction when grinding the wall.
[0043] A limiting part may be provided at the top of the second fixed rod 13 to restrict the second sliding lifting seat 14 from sliding out or disengaging from the second fixed rod 13, thereby allowing the second sliding lifting seat 14 to move within a preset range.
[0044] In a preferred embodiment, a rotating frame 20 is provided on the base 1, and a collection hopper 21 is fixedly provided on the movable end of the rotating frame 20. The collection hopper 21 is located directly below the grinding mechanism when in use. The rotating frame 20 enables the collection hopper 21 to be rotated and folded for storage. When in use, the collection hopper 21 is rotated and unfolded. At this time, the collection hopper 21 adheres to the bottom of the wall under the action of gravity and the rotating frame 20, and the wall plaster under grinding can be collected through the collection hopper 21.
[0045] As a preferred embodiment, a handle 22 is provided on the base 1, and at least four casters 23 are provided on the bottom surface of the base 1. The free movement of the base 1 is achieved by the arrangement of the casters 23 and the handle 22, thereby driving the entire wall sanding equipment to move.
[0046] In use, the device is moved to the side of the wall to be sanded. When the sanding area is small, the first sliding lifting seat 5 is raised or lowered by the lifting drive assembly, thereby adjusting the relative height of the sanding disc 19. At the same time, the second motor 9 drives the rotating rod 10 to rotate. The rotating rod 10 drives the sanding disc 19 to rotate around the axis of the second motor 9 through the connecting shaft 11, thereby adjusting the relative angle of the sanding disc 19. The relative position of the sanding disc 19 is then adjusted according to the different sanding points. Then, the third motor 16 drives the mounting shaft 17 to rotate. The mounting shaft 17 drives the sanding disc 19 to rotate through the mounting bracket 18, thereby sanding the wall through the rotating sanding disc 19.
[0047] When the grinding area is large, the grinding disc 19 can be rotated by the third motor 16 for grinding. The grinding disc 19 can be rotated around the axis of the second motor 9 by the second motor 9. At the same time, the second sliding lifting seat 14 can be moved closer to the rotating mounting seat 12 by the electrically controlled telescopic air rod 24, thereby causing the grinding disc 19 to rotate in a vortex on the wall surface, thus automatically grinding a large area of the wall.
[0048] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
