Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, and specifically to a ceiling polishing device. Background Technology

[0002] In engineering fields such as building construction and post-construction maintenance, roof structures such as building roofs and outdoor baffles need to undergo surface grinding to ensure the smoothness of the appearance or the quality of subsequent coating.

[0003] Currently, the industry mainly relies on handheld grinders for manual ceiling grinding, which has significant technical shortcomings and cannot meet the demands for efficient and high-quality operations. First, ceiling work is conducted at height, requiring operators to use ladders, scaffolding, or other climbing equipment, or to hold the grinder by hand with their arms raised for extended periods. This can easily lead to arm fatigue, and the climbing equipment is difficult to move, requiring frequent adjustments to cover the entire ceiling area, resulting in low work efficiency and unsuitability for large-area operations. Second, because the ceiling is located above the operator, their line of sight is obstructed, and the fit depends entirely on the operator's judgment by feel. This can easily lead to insufficient fit, resulting in localized missed areas, or excessive fit, resulting in over-grinding, which in turn affects the flatness of the ceiling surface. In addition, there are no effective collection measures for the grinding dust, which will scatter everywhere. This dust will further obstruct the operator's view, pollute the working environment, and further restrict the quality and efficiency of the work.

[0004] In summary, existing ceiling sanding methods and devices have significant shortcomings in terms of ease of operation, accuracy of fit judgment, and dust disposal. In order to solve the above problems, we propose a ceiling sanding device. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings mentioned in the background art and provide a ceiling grinding device.

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figures 1-10 The present invention will describe the above technical solution in detail through the following embodiments:

[0047] The ceiling grinding device in this embodiment, such as Figure 1 , Figure 2 As shown, in order to be suitable for large-area grinding operations on the ceiling and different working height requirements, the grinding device in this embodiment includes a stacking mobile vehicle 1 with a lifting pallet 11 installed on it. At the same time, a balance four-bar linkage 2 is installed on the pallet via an electric cylinder 3. The balance four-bar linkage 2 adopts the four-bar linkage structure below the pantograph collector head of rail transit, which can keep the buffer mounting seat 4 installed at the top of the balance four-bar linkage 2 horizontal during the lifting process. This part of the structure is an application of existing product technology, so it will not be explained in detail.

[0048] Traditional disc-type rotary grinders cannot discharge the grinding powder in the middle part in time during the grinding process when they are attached to the ceiling. Repeated grinding will affect the surface grinding quality. Therefore, this device needs to throw off and discharge the grinding powder in time during the grinding process to avoid repeated friction. Therefore, in this embodiment, a limiting grinding component 5 is horizontally installed above the buffer mounting base 4.

[0049] Specifically, such as Figures 3-6 To prevent excessive impact damage to the structure or ceiling caused by the device, the structure is equipped with a buffer mounting base 4, which includes a base plate 41 installed at the top of the balance four-bar linkage 2. A stop arm 43 is rotatably mounted on the base plate 41 via a mounting bracket 42. The stop arm 43 is in an inclined state. A first rotating block 422 is rotatably mounted on the inner end of the mounting bracket 42, and a second rotating block 431 is rotatably mounted on the outer end of the stop arm 43. A plug rod 44 fixedly connected to the first rotating block 422 is inserted into the second rotating block 431, and a spring 45 is fitted on the plug rod 44 to maintain the compressed state of the stop arm 43 being pushed upward.

[0050] To obtain a buffer space, a vertical plate 47 is vertically installed by means of protrusions 421 on both sides of the mounting bracket 42, and a bearing plate 48 is installed above the vertical plate 47. The vertical plate 47 is inserted into the protrusion 421 through a slot 471, and a limiting bolt 46 is threaded on the protrusion 421. The vertical plate 47 moves up and down along the limiting bolt 46 through the vertical lifting groove 472 to obtain a buffer space. It is necessary to keep the stop arm 43 in contact with the top of the slot 471. When pressure is applied from above, it will press down on the vertical plate 47 and compress the spring 45 to maintain a reliable upward reset action and prevent separation during the grinding process.

[0051] However, it should be noted that this embodiment does not use disc grinding, but instead uses a limiting grinding component 5 whose rotating axis is perpendicular to the grinding ceiling, i.e. Figure 3 and Figures 7-10 As shown, the limiting grinding assembly 5 includes a mounting chamber 51 on which a grinding unit 54 is rotatably mounted via a drive motor 53. In this embodiment, the grinding unit 54 includes a collar 542 on which a central cylindrical block 541 is detachably mounted. The collar 542 has grinding discs 543 evenly distributed along its axis on its outer surface. Figure 10 As shown, if the grinding disc 543 is pressed tightly, the clamping cavity 5404 between adjacent grinding discs 543 will close, which will affect the collection of grinding powder.

[0052] Specifically, such as Figure 8The structure shown includes a limiting unit 52 comprising an intermediate frame 521 fixedly mounted on the mounting chamber 51, with two symmetrically arranged side frames 522 rotatably mounted at both ends of the intermediate frame 521. A tension spring 524 is installed between the two side frames 522, and a roller 523 is rotatably mounted at the outer end of the side frame 522 for contacting the roof. The limiting unit 52 avoids the problem of unreliable contact with the roof during the lifting process, allowing for excessive lifting. A buffer space is obtained through the buffer mounting seat 4. In this embodiment, a distance sensor is installed between the bearing plate 48 and the base plate 41 to avoid large-scale errors that could lead to a collision at the top. In addition, this embodiment creatively installs a limiting unit 52 on the top of the mounting chamber 51, which can fit against the roof to be ground, ensuring that when the roller 523 opens and presses against the mounting chamber 51, the clamping cavity 5404 remains open and is not compressed and closed, providing a channel for collecting grinding powder.

[0053] like Figures 8-10 The structure shown has an opening 5401 on the collar 542 that corresponds to and is connected to the clamping cavity 5404. A shaft hole 5403 is provided at the center of the central column block 541. A dust suction chamber 5402 is provided between the shaft hole 5403 and the opening 5401. The dust is sucked up during the grinding process by installing a vacuum cleaner 55 at the shaft hole 5403 at the outer end. The vacuum cleaner has a built-in suction fan and filter, which is existing technology and will not be described in detail. Its main function is to suck the grinding powder onto the filter to reduce the dispersion of grinding powder and its impact on the working environment.

[0054] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
